Per the Garfield County Land Use and Development Code, effective July 15, 2013, Oxy is requesting a Limited Impact Review permit for "Materials Handling and Water Impoundment". The project area is situated in the Resource Land -Plateau zone district. The water to be handled at this facility is produced from drilling, completion and production operations associated with natural gas wells within Oxy's Cascade Creek Operations. Water that is produced from these operations is classified as an exploration and production (E&P) waste by the COGCC. Pursuant to COGCC Rule 908, this facility will also be permitted as a Centralized E&P Waste Management Facility with the COGCC. The existing produced water impoundments are currently permitted as a Form 15 use by the COGCC. Oxy is pursuing permitting for the existing water impoundments as E&P Waste Management facilities and is in the process of submitting a Form 28 to the COGCC for their review. All water stored at this location will be from a non -tributary water source within the Williams Fork and Niobrara formations. Pond G is in the SE 1/4 of the NW 1/4 of Section 16, Township 6 South, Range 97 West, of the 6th Principal Meridian, in unincorporated Garfield County, Colorado. Oxy is the surface owner. The proposed Centralized E&P Waste Management facility will allow for effective re -use of water volumes to conserve resources, improve safety and environmental exposure, and reduce costs. The goal of this water impoundment project is to conserve water by recycling flow -back and produced water for re -use in well stimulations or drilling. The ability to temporarily store water at this location has several key benefits: • Reduced trucking / improved safety • Use of engineering controlled transfer system • Reduction in volumes of disposed water • Conservation of freshwater • Reduced road maintenance • Overall reduction in development and operating cost 760 Horizon Dr., Suite 102 TEL 970.263.7800 Grand Junction, CO 81506 FAX 970.263.7456 www.olssonassociates.com Details of this request along with the information required by Garfield County's (GarCo) Limited Impact Review (LIR) application are provided within the context of this submittal.

The project has been designed in accordance with the Colorado Oil and Gas Conservation Commission (COGCC) standards. The planned use of the site is a water impoundment and storage area. A Reclamation Plan has been prepared by Olsson Associates to accommodate this project. Grading and Drainage Plan 1. Site Map: The proposed site will not differ from the existing site. The existing site features are identified within the Reclamation Plan. 2. Drainage Structures: Additional design is not anticipated since the proposed site and the existing site are the same. Additional disturbance is not anticipated. 3. Topography: The attached exhibit within the Reclamation Plan illustrates the existing topography of the site. Additional grading is not anticipated. 4. Grading Plan: The existing topography is anticipated to remain. 5. Soil Stockpile and Snow Storage Areas: Soil stockpiles and snow storage is not anticipated to differ from the existing use. 6. Drainage Plan: The existing drainage patterns are not anticipated to be modified. 7. Equipment Storage Areas: A proposed use of the facility is for storage. No hazardous material is expected to be stored at the site. Best management practices outlined within the stormwater management plan referenced in the Reclamation Plan will be followed. 8. Temporary Roads: Temporary roads are not anticipated with the development. The existing infrastructure is expected to serve the site. 9. Areas of Steep Slope: The existing side slopes surrounding the site are steeper than 20% and are expected to remain undisturbed. 10. Construction Schedule: A construction schedule is not anticipated since the site currently exists. 11. Permanent Stabilization: The site is currently stabilized through the use of existing vegetation. 760 Horizon Drive TEL 970.263.7800 Grand Junction, CO 81506 FAX 970.263.7456 www.oaconsulting.com 12. Erosion Control Measures: Erosion control measures are not anticipated since the site is currently stabilized. 13. Estimated Cost: Construction was under an APD. This is an existing site and no new construction is anticipated. 14. Calculations: Drainage design is not included since there are no anticipated changes to drainage patterns. 15. Neighboring Areas: The site is surrounded by oil and gas activity. 16. Stormwater Management: Stormwater management will be in accordance with the previously prepared stormwater management plan referenced within the Reclamation Plan. 17. Stormwater Management Plan: A copy of the permit is included within the Reclamation Plan. 18. Reclamation Plan: A Reclamation Plan is included with the submittal. 19. Hydraulic Calculations: Drainage design is not included since there are no anticipated changes to drainage patterns. 20. Maintenance Requirements: Maintenance requirements are discussed within the stormwater management plan referenced within the Reclamation Plan. 21. Spill Prevention Control and Countermeasures Plan: Not applicable. 22. Additional Information: None. 23. Signature Block: See below. Additional construction is not anticipated, therefore, the previously stabilized areas are not anticipated to be disturbed.

Upon closure of the site, revegetation activities are anticipated to take no longer than forty (40) days weather permitting. Upon closure of the site, the disturbed area will be re-contoured at slopes no greater than 2:1 to catch the existing terrain. Topsoil will be replaced on the disturbed areas. The entire disturbed area will be reseeded with the following seed mixture: Mixed Mountain Shrubland, Including Oakbrush Common Name Scientific Names Form PLS 1 bs/acre* Thickspike Wheatgrass Elymus lanceolatus ssp. lanceolatus, Agropyron dasystachyum Sod- forming 3.4 Bluebunch Wheatgrass Pseudoroegneria spicata, Agropyron spicatum Bunch 3.7 Bottlebrush Squirreltail Elymus elymoides, Sitanion hystrix Bunch 2.7 Slender Wheatgrass Elymus trachycaulus, Agropyron trachycaulum Bunch 3.3 Canby Bluegrass Poa canbyi, P. secunda Bunch 0.6 Mutton Bluegrass Poa fendleriana Bunch 0.6 Letterman Needlegrass Achnatherum [Stipa] lettermanii Bunch 1.7 Columbia Needlegrass Achnatherum [Stipa] nelsonii, Stipa Columbiana Bunch 1.7 Indian Ricegrass Achnatherum [Oryzopsis] hymenoides Bunch 1.9 Junegrass Koeleria macrantha, K. cristata Bunch 0.1 *Based on 60 pure live seeds (PLS) per square foot, drill -seeded. Double this rate (120 PLS per square foot) if broadcast or hydroseeded. Top Soil Management Topsoil has been reutilized during the initial construction of the site for initial reclamation. During closure of the site the topsoil will be re -stockpiled so that it will not interfere with closure activities. Should the reclamation activities during the closure phase exceed forty (40) days, appropriate measures will be taken to protect all topsoil stockpiles (covering, seeding, windbreaks, etc.). Following final contouring, all disturbed areas will be covered evenly with the stockpiled topsoil. The topsoil will be heavily pocked using the excavator bucket to form an uneven soil surface 1 complex which will aid in revegetation. Soil amendments or import of new topsoil is not anticipated. Review of the vegetation establishment will be required to determine whether soil amendments are required at a later date. (Attachment A). Seeding Procedures and Schedules As recommended grass mixture reseeding will be done in late autumn in order to take advantage of natural precipitation for the region. The reseeding rate should be doubled for broadcast application. Oxy's contractor will utilize a no -till -drill without any soil preparation other than simple grading to slope and waterbars, where applicable. It is anticipated that the disturbed areas will be returned to match the original vegetative state. Seeding will be conducted by means of drilling the prescribed seed mix according to the recommended rate. The seed will be drilled with a common range drill at a depth of 0.25 — 0.5 inch beneath the soil surface. The reseeding will be monitored and reseeded as appropriate until the reclamation standards are acceptable to Garfield County Vegetation Management. The reclaimed site will be monitored for stormwater and noxious weeds. Disturbance area The project has an anticipated total disturbance of approximately 4.1 acre. (178,596 square feet). Engineer's Opinion of Probable Cost Below is a table that outlines the estimated costs associated with the revegetation of the project during final closure. There are no costs associated with the initial reclamation. The estimate is an opinion of probable cost and may vary based upon site conditions encountered or market conditions related to the unit cost. (JoLssoN ASSOCIATES Olsson Associates 760 Horizon Drive, Suite 102 Grand Junction, CO 81506 REVEGETATION COST SUMMARY PROJECT: Pond G LOCATION: Garfield County, CO DATE: 8/1/13 Item Description (Source of Cost) Garfield County Vegetation Management Cost/ Acre $2,500 Total Acres 4.1 Estimated Total Cost $10,250 (costs have been provided by Garfield County Vegetation Management) 2 Drainage and Erosion Control Plan The primary disturbance anticipated with the closure Pond G is re -grading. Topsoil will be stockpiled so that it will not interfere with closure activities. Should the construction activities during the closure phase exceed forty (40) days, appropriate measures will be taken to protect all topsoil stockpiles (covering, seeding, windbreaks, etc.). The final reclamation plans prepared by D.R. Griffin and Associates, Inc illustrate the proposed final grades. Drainage Nolte Associates prepared the Regional Drainage Analysis. The improvements associated with this project are located within the CA02 drainage basin as described within the Regional Drainage Analysis. This project is not anticipated to significantly alter the drainage patterns or flow rates described within the Regional Drainage Analysis. Additional analysis may be warranted due to the nature of construction activity associated with this project. However, it is expected that existing drainage measures will be maintained. Deviation from the Regional Drainage Analysis is not expected, however, if site conditions dictate a deviation then a Colorado Registered Professional Engineer shall be consulted. The Regional Drainage Analysis prepared by Nolte Associates demonstrating drainage patterns for the project area is included as Attachment B. Erosion Control Measures Olsson Associates prepared a Stormwater Management Plan (SWMP) for Cascade Creek Development. It is anticipated that the project will be in conformance with Oxy's SWMP (permit no. COR038414). The Stormwater Management Plan will be revised accordingly. An exhibit demonstrating approximate locations of anticipated erosion control measures is included as Attachment C. Closure will be completed as described in the Reclamation Plan and SWMP. The recommendations associated with the Reclamation Plan and review of the Drainage and Erosion Control Plan were prepared on behalf of Olsson Associates under the supervision of: Wyatt E.

Background The Colorado Noxious Weed Act (C.R.S. Title 35, Article 5.5) requires that "noxious weeds" be managed on private and public lands. The Act further declares that control of noxious weeds should use methods that are least damaging to the environment but also practicable and economically reasonable. The state requires management of noxious weeds included on one of three lists (see Appendix A): List A — designated for statewide eradication; List B — managed to prevent further spread and, for selected species, designated for eradication in large areas; and List C — of more localized concern, but for which the State will provide education, research, and biological control assistance to jurisdictions that choose to manage the species. OXY USA WTP LP and OXY USA Inc. (individually and collectively referred to herein as "Oxy"), are affiliated companies that separately own and operate certain mineral properties in the State of Colorado. This plan is intended for all Oxy operations in order to comply with all state and federal requirements including the Colorado Noxious Weed Act, Colorado Oil and Gas Conservation Act, Bureau of Land Management (BLM) and Forest Service (FS) National Invasive Weed Strategies, Mesa County and Garfield County weed standards. 2. Compliance Statements Oxy will manage all noxious weeds, as defined by the Mesa County, Garfield County or State Law (CRS 35-5.5), in all newly disturbed project areas using recommendations identified in this plan or those provided by biological consultant at the time of project specific inventories. The term, "disturbed area" includes all access roads, easements, pipelines, special purpose pits, berms, soil stockpiles, well pads, electrical and compressor stations and other structures, and other areas disturbed by project activities. Oxy will immediately report all State List A and List B populations to be eradicated and any other species slated by Mesa and Garfield Counties for eradication upon discovery to the appropriate County designee. 3.

Locations Oxy has active and inactive leases for gas exploration in the following areas of Mesa and Garfield Counties: • Cascade Creek (Garfield County, Colorado) • Collbran Area (Mesa County, Colorado) Oxy operates on split estate, wholly federal (both BLM and USFS), and wholly private land and lease holdings. 5. Land Use Objectives Oxy conducts natural gas exploration on lease holdings in Colorado. Land uses and types of facilities to be developed include access roads, pipelines, well pads, compressor stations, staging/storage areas for equipment and supplies, and other associated natural gas development activities. Some of the developments are short- term temporary disturbances, such as staging areas and pipelines, while the roads and well pads will be in place for an estimated 20-30 years. 6. Weed Management Objectives and Implementation Strategies The following are the overall objectives of Oxy's weed management plan. Specific actions to be taken to meet these objectives are detailed in Section 6. 1) Inventory and monitor existing noxious weed infestations using GPS or other mapping techniques and consistent field documentation; 2) Prevent new infestations of noxious weeds; 3) Implement Integrated Weed Management (IWM) to control or manage noxious weed populations; 4) Maintain weed inventory, herbicide application and mapping records; 5) Restore disturbed areas to their proper ecological function to protect native plant ecosystems and watersheds from degradation by noxious weeds. 6.1 Inventory and Monitoring Before a new site is developed, Oxy will inventory the site and adjacent areas for noxious weeds, including access roads and other probable weed ingress routes. Noxious weed locations (List A and List B species) will be collected with a GPS unit. Any noxious weed infestations found will be treated before site disturbance, if timing is appropriate. If the season is not appropriate for weed treatment, activities may proceed and the weeds will be monitored and treated during the appropriate season. Weeds on adjacent properties may be treated as appropriate with permission of the landowner. Populations of Colorado or County List A and List B species (see Appendix A) will be reported immediately to the County Weed Manager. On Federal property or for federal projects, a Noxious Weed Inventory record will be completed each time a List A or B weed infestation is inventoried (with the exception of redstem filaree and quackgrass), and the populations will be reported. Monitoring will be conducted at least once a year, early in the growing season, by Oxy staff or contractors, and in coordination with BLM or FS staff on federal lands. For most of Oxy's operation areas, monitoring will occur between May and July. All previously treated noxious weed sites will be monitored for regrowth and scheduled for re -treatment as necessary. All disturbed areas under Oxy management will also be monitored to ensure there are no new weed infestations. 6.2 Prevention The purpose of prevention measures is to preclude the introduction of new or existing noxious weeds from the project area to un -infested areas or from adjacent land into the project area. 6.2.1 Construction Prevention Measures Construction equipment entering project areas (backhoes, trackhoes, dozers, blades, rollers, lowboys, equipment trailers, etc.) will be power washed or otherwise cleaned. "Equipment" is defined as any earth moving and any other machinery, trucks or vehicles, trailers and tools. On Federal property, equipment may be inspected by USFS or BLM personnel. Pickup trucks, SUVs, vans, water trucks, and pipe trucks should also be clean but do not require inspection prior to entering federal lands. Track pads, gravel beds or rumble strips will be installed at ingress/egress points to the site to limit weed propagules from entering or leaving the site. Soils from infested areas of the project site will not be moved off site, but will be stockpiled and treated for weeds as necessary. If infested soils are moved off site, they will be kept on Oxy -managed property, monitored, and treated as necessary. Stockpiled soils will be monitored and treated to control noxious weeds. All purchased products used in development and reclamation of a site will be inspected or certified as weed -free whenever possible, including soils, rock and gravel, seeds, mulch and erosion control products. 6.2.2 Revegetation The goal of reclamation and revegetation of a site after disturbance is timely establishment of a desirable plant community and prevention of noxious weed infestation. "Timely" is defined as "by the end of the second year of project completion" (BLM 2007). Elements of successful revegetation include the use of topsoil that was set aside during construction and kept weed -free; reseeding with appropriate species to establish plant cover, and stabilization of the soil surface with the appropriate mulches, tackifiers, and erosion control products as needed. Plans for revegetation and reclamation of disturbed areas are site-specific, and will include a plant list, method of seeding, how seeding success will be determined and how the revegetated area will be monitored. Most private landowners request re -seeding with common pasture grasses, including timothy, (Phleum pratense), brome grasses (Bromus or Bromopsis), orchardgrass (Dactylic glomerate), and oats, tricale, rye, or wheat as an annual covercrop. USFS and BLM seed mixes are compiled on a site-specific basis, according to elevation and existing vegetation community on the site. Non-native, non-persistent sterile grasses may be used to provide ground cover for soil stabilization and weed suppression during temporary reclamation on both private and federal land. See Appendix C for a sample Oxy Revegetation and Reclamation Plan. Certified weed seed free straw, hay, mulch, seed or other materials will be used for soil stabilization and/or revegetation purposes (Colorado Department of Agriculture certified inspector to State standards). Seed tags will be available for inspection upon request of the Inspector. Topsoil that is stock piled for more than one year will be seeded according to above standards at the earliest practical time to reduce the possibility of noxious weed establishment. Revegetation efforts will be monitored annually until successful establishment of desirable or intentionally planted seed or plants is confirmed. Noxious weeds found in revegetation will be documented, and managed per guidelines in this Weed Management Plan. 6.3 Control and Management A comprehensive multi -strategy approach utilizing IWM will be employed to detect, map, treat and control noxious weeds. Treatments will include herbicide, cultural, mechanical, revegetation, and biological control alone or in combination as necessary for efficient weed control. On Federal lands, control and management methods (including herbicide use) will be verified and approved with the appropriate land management agency representatives. Activities on BLM lands in Colorado requires submittal of a "Pesticide Use Proposal Form" (BLM 2007). The accompanying treatment tables describe the management methods, rates, and timing of control measures for specific targeted weeds (see Table 1 and Table 2). Treatment application records will be retained by Oxy and available for inspection by contacting personnel listed in Section 3.. Table 1.

Appendix B Excel Spreadsheet Components and Example Tables for Pesticide Reporting The Excel spreadsheet table will contain the data fields listed below. This information should have been recorded on Noxious Weed Inventory and Pesticide Application records completed during the field season. The Excel spreadsheet will contain a new entry for each weed inventory and/or pesticide application. Infestation Number (IN #): Needed when List A or List B species (with the exception of redstem filaree and quackgrass) are inventoried and treated. This is the unique number or code associated with each weed infestation. Date: Date of the weed inventory and/or treatment Observer/Applicator (Obs/Appl): Person conducting the inventory and/or applying the herbicide. Weed Name or Bare Ground: Common name of the weed. If it was a bare ground treatment state as such. UTM Easting (UTM E), Northing (UTM N) and Zone (Z) (should always be in NAD 83) or use Lat and Long if preferred. Be consistent with which one is used. Infested Acres (Inf Acres): List how many acres are covered with the weed. Density (Dens) i.e. Cover: L= Low (less than 5% total canopy cover) M = Moderate (5% - 25% canopy cover) H = High (more than 25% canopy cover) Surface ownership (Own): BLM, FS or private Herbicide Trade Name (Tr Name) or Treatment Method — if a manual or biological treatment state as such. Chemical Names (Chem Name) — Only needed when using an herbicide with multiple active ingredients or when using a mixture of chemicals. For example, if using Sahara DG which has two active ingredients, imazapyr and diuron, enter the first two letters of each active ingredient. e.g. im + di. See Excel spreadsheet example. Application Rate (Pounds Active Ingredient (A.I.)/Acre or Pounds Acid Equivalent (A.E.)/Acre): For those herbicides with multiple active ingredients, multiple columns for the application rates are provided. Application rates should be entered in the same order chemical names are entered. For example, for Sahara DG, the A.I./acre of imazapyr would be entered in the first Application Rate (AR #1) column. The A.I./acre of diuron would be entered in the second Application Rate (AR #2) column. If an additional chemical was used in the mix it would be entered in the third Application Rate (AR #3) column. Total Pounds Active Ingredient (A.I.) or Acid Equivalent (A.E.) Applied: For those herbicides with multiple chemicals, multiple columns for the pounds of A.I./A.E. are provided. Pounds of A.I./A.E. should be entered in the same order chemical names are entered. For example, for Sahara DG, the pounds of A.I. of imazapyr would be entered in the first Total Pounds A.I./A.E. (Al AE #1) column. The pounds of A.I. of diuron would be entered in the second Total Pounds A.I./A.E. (AI AE #2) column. If an additional chemical was used in the mix it would be entered in the third Total Pounds A.I./A.E. (Al AE #3) column. Acres Treated: This should equal the Total Pounds A.I./A.E. divided by the Application Rate in Pounds A.I./A.E.

Upon termination of the development and production activities, the facility will be reclaimed, as outlined below: • All equipment and structures will be removed. • OXY will remove all safety and storm water BMPs, and other surface objects from the premises. • OXY will restore the site to pre -facility conditions by re -contouring and re - vegetating the site. Top soil will be redistributed across the site and will be reseeded with an approved seed mix (see attached seed mix recommendation). • OXY will monitor the site to ensure that 70 percent of the pre-existing vegetation is achieved, per the requirements of the area wide CDPHE Stormwater Permit for Cascade Creek and Collbran Developments. Seedbed Preparation and Slope Reconstruction: Cut and fill slopes will be backfilled and re-contoured to a slope of 3:1 — 2.5:1 or less in instances where necessary to match the existing natural contours. Following final contouring, all backfilled or ripped surfaces will be covered evenly with topsoil. Re - contouring should form a complex slope with heavy pocking. In areas with slope greater than 3 percent, imprinting of the seed bed is recommended. Final seedbed prep will consist of scarifying/imprinting the topsoil prior to seeding. Imprinting can be in the form of dozer tracks or furrows perpendicular to the direction of slope. When hydro -seeding or mulching, imprinting should be done prior to seeding, unless the mulch is to be crimped into the soil surface. If broadcast seeding and harrowing, imprinting will be done as part of the harrowing. Furrowing can be done by several methods, the most simple of which is to drill seed perpendicular to the direction of slope in a prepared bed. Other simple imprinting methods include deep hand raking and harrowing, always perpendicular to the direction of slope. All compacted areas will be ripped to depth of 18" with max furrow spacing of 2'. Where practicable, ripping will be conducted in two passes at perpendicular direction. Topsoil: Following final contouring, all backfilled or ripped surfaces will be covered evenly with topsoil. The topsoil in the cut slope on the back of the pad will be heavily pocked using the excavator bucket to form an uneven soil surface complex which will aid in revegetation and help with slope stabilization. The fill slope, and remaining disturbed, and reclaimed areas will be track walked to aid in revegetation and slope stabilization. In areas that may not have been disturbed during the reclamation process or areas of suspected compaction that will be reseeded, measures will be taken to loosen and spread the topsoil. These measures may include scarifying the soil by racking or harrowing the soil. Seed Mix: Seed mix used for reclamation will be taken from the attached seed mixtures. Seeding Procedures: For best results and success, the recommended grass mixture reseeding should be done in late autumn in order to take advantage of natural precipitation for the region. The reseeding rate should be doubled for broadcast application. Preferred seeding method is multiple seed bin rangeland drill with no soil preparation other than simple grading to slope and imprinting and waterbars, where applicable. Alternative seeding methods include, but are not limited to: • No -till -drill (no soil preparation required); • harrow with just enough soil moisture to create a rough surface, broadcast seed and reharrow, preferably at a 90 degree angle to the first harrow; • hydro -seeding (most economical in terms of seed cost); and • hand raking and broadcast followed by re -raking at a 90 degree angle to the first raking. • These are not the only means of replanting the site. However, these methods have been observed to be effective in similar landscapes. The prepared soils will be seeded (weather permitting) no more than 24 hours following completion of final seedbed preparation. The seeding will be conducted by means of drilling the prescribed seed at prescribed seeding rate. The seed will be drilled with a common range drill at a depth of 0.25 — 0.5" beneath the soil surface. The seed will be drilled horizontally across the pad faces and perpendicular to the track walking when possible. When slope gradient less than 2.5:1 exists and drilling is not possible from a mechanical and safety standpoint the soils will be broadcast seeded at twice the prescribed amount. The reseeding will be monitored and reseeded as appropriate until the reclamation standards detailed above are met.

Mineral Owners See Adjacent Property Owners section for complete list of Mineral Rights Owners. 3. Adjacent Land Use Land uses adjacent to the project site are predominately natural gas operations and seasonal cattle grazing. The project site is located within a 7,732.52 acre parcel. Land uses on adjacent properties also include natural gas and agricultural operations. 4. Site Features The proposed site is located at an approximate elevation of 8,300 feet above sea level and is in Section 16, Township 6 South, Range 97 West of the 6th P.M. The project area is located above Cascade Canyon and the Conn Creek drainage. Prior to being disturbed for a production pond, the site contained a mix of scrub -shrub upland habitat dominated by sagebrush and Gambel oak. 5. Soil Characteristics The soil at this location consists of 52-Northwater - Adel, 5 to 50 percent slopes and 57 - Parachute — Rhone, 5 to 30 percent slopes. The majority of the actual storage area is located on the 57 -Parachute -Rhone soil type. Both soil types are considered to exhibit "well drained" qualities with no frequency of flooding or ponding. Both soil types have low characteristics for corrosion of concrete and moderate corrosion of steel. The characteristics of these soils will not create significant restrictions on the development of a Centralized E & P Waste Management Facility. 760 Horizon Drive, Suite 102 TEL 970.263.7800 Grand Junction, CO 81506 FAX 970.263.7456 www.olssonassociates.com OXY USA WTP LP Pond G Facility 6. Geology and Hazard Topography The Oxy Pond G Facility consists of adjacent ponds that are being permitted as one facility. The site is shown on the U.S.G.S. Circle Dot Gulch 7.5 -minute topographic map. The facility is located near the rim of Cascade Canyon approximately 15 miles north of the town of De Beque in western Garfield County, Colorado. The site is located near the center of the Piceance Basin, an elongated, irregularly-shaped structural depression in the earth's crust resulting from tectonic forces associated with the uplift of the Rocky Mountains through geologic time. The general terrain surrounding the facility consists of rugged canyons incised into the Roan Cliffs. The present topography is the result of uplift combined with stream erosion. The erosion produced a series of high plateaus and deep valleys associated with the down cutting of Colorado River located to the south. The site is located approximately 550 feet northwest of an unnamed drainage to Cascade Canyon. The site lies at an elevation of approximately 8,260 feet above mean sea level. The elevation of Cascade Creek lies at more than 1,000 feet below the site elevation. Soils The proposed facility is underlain by soils mapped by the U.S. Natural Resources Conservation Service as the Parachute — Rhone loams, which are found on mountain sides and on ridge crests with 5 percent to 30 percent slopes, at elevations of 7,600 feet to 8,800 feet above mean sea level. The unit is about 55 percent Parachute soil and 35 percent Rhone loam. The two soils occur as areas so intricately intermingled that mapping them separately was deemed impractical at the scale used in the soil survey. The Parachute soil is moderately deep and is well drained. It formed in residuum derived dominantly from sandstone, siltstone, and shale. Typically the surface layer consists of grayish brown loam and is about ten inches thick; while the subsoil is brown very channery loam about 15 inches thick, with rippable, fractured siltstone encountered at depths of about 25 inches. Permeability is moderate in the Parachute soil, and the available water capacity is very low. Runoff is medium or rapid, and the hazard of water erosion is moderate to very severe. The Rhone loam is deep and well drained and is formed in residuum and colluvium derived predominantly from sandstone or shale. Typically the surface layer is brown channery loam about six inches thick, the subsoil is very dark grayish brown loam about 10 inches thick, and the next layer is a dark grayish brown channery loam about 29 inches thick, and the subsoil is brown very channery loam about 16 inches thick. Rippable, fractured siltstone is encountered at depths of about 55 inches. Permeability of the Rhone loam soils is moderate, and the available water capacity is also moderate. Runoff is medium or rapid, and the hazard of water erosion is moderate to very severe. Bedrock Geology The bedrock underlying the proposed facility is composed of the Tertiary age Uinta Formation or the Parachute Creek Member of the Green River Formation. The Uinta Formation consists of permeable, poorly sorted, fine to coarse sandstone with some Impact Analysis Page 2 OXY USA WTP LP Pond G Facility siltstone and mudstone, becoming more coarse-grained and permeable toward the top of the formation. The Uinta Formation and the Parachute Member of the upper part of the Green River Formation comprise the Uinta — Animas aquifer in the Piceance Basin. The Uinta Formation lies stratigraphically above the Tertiary age Parachute Member of the Green River Formation. The Parachute Creek Member consists primarily of dolomitic marlstone. Kerogen, a waxlike hydrocarbon, is present in some parts of the Parachute Creek Member in the Piceance and Uinta Basins. Marlstone containing large concentrations of kerogen is referred to as "oil shale" and is generally not as fractured and contains smaller concentrations of kerogen. Fractures and dissolution openings along fractures in the marlstone form the principal pathways for water movement in the aquifer (Robson and Banta, 1995). Oil shale is generally less permeable and forms confining units. The Mahogany zone is an oil shale bed within the Parachute Creek Member that is an example of a confining unit found within the Piceance Basin. A saline zone in the lower marlstone of the Parachute Creek Member is found within the central part of the Piceance Basin and contains the minerals nahcolite and halite, is not extensively fractured, and forms part of the relatively impermeable lower confining unit of the aquifer (Robson and Banta, 1995). The depth to the top of the Mahogany zone in the vicinity of the site is expected to lie at an elevation of 6,000 feet. The Garden Gulch Member, Anvil Points Member, and Douglas Creek Member of the Green River Formation and the Tertiary age Wasatch Formation forms a confining unit that separates the Uinta — Animas aquifer from the underlying upper Cretaceous Mesaverde aquifer. Local and Regional Geologic Structure The water storage facility is located on the southwestern limb of the Crystal Creek Anticline and the northeastern limb of the Clear Creek Syncline. The northwest trending fold system of the Crystal Creek anticlinal nose and the Clear Creek Syncline begins near the Colorado River and extends northward for approximately 30 miles into the southwestern part of the Piceance Creek Basin. A part of the Clear Creek syncline occupies the southwestern part of this area and the trace of its axis is closely parallel to that of the Crystal Creek anticline. The Clear Creek syncline is a broad shallow fold the trace of which closely parallels the axis of the Crystal Creek anticline. The Crystal Creek anticlinal nose forms the southeastern element of an anticlinal fold that trends across the southwest part of the Piceance Basin. The fold plunges to the northwest and terminates near the western boundary of the area in a structural saddle (Hail, 1992). The anticline is somewhat asymmetrical and has steeper dips on its southwest limb of about 200 feet per mile and gentler dips on its northeastern limb of about 65 feet per mile (Hail, 1992). No major faults are present in the project area. Two small groups of normal faults are present in the southern extent of the Roan Plateau with one set approximately 15 miles northeast and a second smaller group about 20 miles northwest of the project site (Hail, 1992). Impact Analysis Page 3 OXY USA WTP LP Pond G Facility Geologic Hazards There are no major faults in the central Roan Plateau area (Hail, 1992). Minimal seismic activity near the proposed disposal facility has occurred in recent geologic time. One earthquake of magnitude greater than 5.0 occurred in Garfield County since the early 1960s when proper instrumentation was implemented in the state of Colorado. The epicenter of this earthquake was approximately 17 miles southeast of the project site. A second recorded earthquake greater than 5.0 occurred in Rio Blanco County with an epicenter about 20 miles northwest of the project site. Mesa County has historically experienced few earthquakes. The USGS has rated Mesa County as having low to moderate earthquake hazard, although no specific seismic study has been done in Mesa County. According to the Colorado Geological Survey, no Quaternary -age faults are present in the Roan Plateau area (Widmann and others, 1998). However, the Geologic Map of Colorado (Tweeto, 1979) shows northeast -southwest trending normal faults exist in the Cretaceous bedrock near the Douglas Creek Arch and the western edge of the Piceance Basin. In addition, a series of normal faults trace along the eastern Piceance Basin boundary near the Grand Hogback to the east. Although faults are not always visible at the surface, this does not preclude the chance of an earthquake happening in the area at some point in the future. According to the Colorado Earthquake Hazard Mitigation Council (2008), "Earthquakes can also occur on faults that do not rupture the ground surface or on faults that are not yet recognized as being hazardous. These so called "random" earthquakes are considered in most hazard analyses to help account for faults that are not apparent at the earth's surface." No surficial geologic hazards (landslide, mudflow, fan) or soils hazards have been mapped in the immediate vicinity of the proposed facility. The site is not located in an area mapped as a floodplain hazard by the Federal Emergency Management Agency (FEMA). However, because of the natural slope above the property within the northeast - to -southwest oriented drainage, overland flow is possible in the event of an extreme precipitation event. Although records of extreme rainfall events are unavailable for locations on top of the Roan Plateau, climate records since the mid -20th century indicate that the record 24-hour rainfall amounts at Grand Junction, Palisade, and Parachute have not exceeded 2 inches (Western Regional Climate Center, 2011). The duration of these events within a 24 hour period is not known, and it is possible that a short burst of intense rainfall event could cause local overland flow in the watershed that encompasses the project site if a precipitation rate exceeds the infiltration rate of the watershed soils. The primary limitations for shallow excavations are based on the slopes and severe seepage. Consideration will be given to the design and construction of this facility to ensure that slopes are graded appropriately to minimize the potential for cutback caving. The suitability of the soils in the project area is identified as being somewhat to very limited in regard to the construction of ponds and embankments. The limitations identified are primarily applicable to unlined water impoundments. Consideration will be given to design and construction characteristics related to the area soil thickness and Impact Analysis Page 4 OXY USA WTP LP Pond G Facility depth to bedrock to mitigate these limitations. Consideration will also be given to the design and operation of the high density polyethylene (HDPE) liner system for the impoundments, which will mitigate potential seepage and leaks. Surface Water Features Surface water features within two miles of the project site include Cascade Canyon located approximately 1,660 feet to the southeast of the water treatment facility, and an unnamed tributary drainage to Cascade Canyon located approximately 550 feet to the southwest. The site lies on a drainage divide between Cascade Creek to the east and Conn Creek to the west - northwest. If a produced water spill were to occur and leave the site, it is expected that it would flow toward Cascade Canyon. The site is shown on the USGS 1:24,000 topographic map (Circle Dot Gulch Quadrangle). Cascade Creek has perennial flow, although no flow records are available to determine the flow conditions in these drainages. There are no springs shown in Section 16, Township 6 South, Range 97 West. Shallow Groundwater and Maior Aquifers Shallow groundwater is not expected to occur in close proximity to the site due to the site being located on a prominence of Cascade Canyon at an elevation of approximately 8,400 feet. Cascade Canyon is the nearest surface water and lies at elevations of 7,400 feet to 8,200 feet. Major aquifers in the area consist of the Uinta — Animas aquifer, and according to published geologic maps, the bedrock exposed at the surface consists of the Uinta Formation. The Uinta — Animas aquifer in the Piceance Basin consists of the Uinta Formation and the Parachute Creek Member of the Green River Formation. Much of the intergranular space in the sandstone and siltstone is filled by sodium and bicarbonate cements; however, fractures are numerous and produce substantial permeability. Water Wells within the Site Boundary According to the COGCC website and the Colorado Division of Water Resources there are no permitted water wells within Section 16, Township 6 South, Range 97 West. The nearest permitted water wells are located in Section 17, Township 6 South, Range 97 West, at a distance of a mile away from the site. These wells are monitoring wells owned by Oxy, at a lower elevation than the site, but are located cross gradient to the site and are located across the Conn Creek and Cascade Creek drainages. No springs are shown in Section 16 or Section 17; however springs are shown in Section 15 to the southeast across the Cascade Canyon. The springs are located at an elevation of less than 8,200 feet above mean sea level and are cross gradient from the site. Hydrologic Properties of Shallow Groundwater and Major Aquifers The Uinta — Animas aquifer in the Piceance Basin receives about 24,000 acre-feet per year of recharge, primarily in the upland areas near the margins of the aquifer. Discharge is approximately equal to recharge and primarily occurs in the valleys of Piceance Creek and other tributaries to the White River or in the valley of the Colorado River and its tributaries (Robson and Banta, 1995). Impact Analysis Page 5 OXY USA WTP LP Pond G Facility The permeability of the major formations in the Piceance Basin aquifers is relatively low. Permeability of the Uinta — Anima aquifer is dependent on the location and orientation of fractures. The potentiometric surface of the Uinta — Animas aquifer generally ranges from about 100 feet above land surface to 500 feet below land surface; the surface generally is near or above land surface in valleys in areas of groundwater discharge. Larger depths to water are more common in highland areas that are remote from streams or other sources of recharge (Robson and Banta, 1995). In the Piceance Basin, the potentiometric surface ranges in altitude from about 6,000 feet to 8,500 feet, and groundwater primarily flows toward the discharge areas along Piceance and Yellow Creeks (Robson and Banta, 1995). The total dissolved solids in the aquifer range from 500 milligrams per liter (mg/L) to 3,000 mg/L. Site Location in Relation to Nearby Floodplains The facility is not within a mapped FEMA flood hazard zone; however, it is located near the rim of the Cascade Creek canyon an area that may be prone to flash floods. The site is located within 1560 feet of Cascade Creek, but is at an elevation of 200 feet to 400 feet above the creek. The site is not subject to COGCC Rule 317B since it is not close to the segment of the Colorado River that supplies the town of De Beque with drinking water. Existing Shallow Groundwater Quality Baseline groundwater quality sampling should occur prior to facility construction or modification to document pre -development conditions at the project site, as data in the area is currently not available. The groundwater quality, where it is present, is expected to be relatively fresh to `bicarbonate' type groundwater. Potential for Impacts to Nearby Surface Water and Groundwater Cascade Creek could potentially be adversely impacted if a release from the facility were to reach it. Shallow groundwater resources are not expected at this location. The pond will be constructed with a HDPE plastic liner to prevent seepage. 7. Groundwater and Aquifer Recharge Areas The proposed project site is not located in any mapped floodplain. An individual septic disposal system (ISDS) will not be used at this site so soils will not have to support waste disposal. The site has been graded for use as a pond facility. BMPs will be implemented to control stormwater run-off and soil erosion. 8. Environmental Impacts a. Determination of long-term and short-term effects on flora and fauna The conversion of the site will not have a significant effect on the local flora and fauna. The site has been previously disturbed and graded for a pond facility. No critical wildlife habitat will be lost due to the conversion of the pad site to a centralized E & P waste facility. Noxious weeds will be controlled on the site during the life of the project. The site will be reclaimed after it is no longer required for natural gas production. Impact Analysis Page 6 OXY USA WTP LP Pond G Facility Oxy commissioned ERO Resources Corporation (ERO) to prepare a biological resources survey of the site and that report is included as an exhibit to this application. According to ERO, the site has the potential for only one federally threatened, proposed and candidate species to occur in the project area. ERO surveyed the project site for the potential habitat for the greater sage grouse. They found the area to be poor habitat for this species. This conclusion corresponds with the Suitable Habitat Results Map of the adopted Garfield County Greater Sage - Grouse Conservation Plan. The project area is not located in an elk winter concentration area. ERO determined that there are no raptor nests near the project area. The proposed site is within one- half mile of raptor cliff habitat. b. Determination of the effect on designated environmental resources, including critical Wildlife Habitat As stated above, the site has been previously disturbed and graded for a production pond. No critical wildlife habitat will be lost due to the conversion of the pond to an E & P waste facility. Noxious weeds will be controlled on the site during the life of the project. The site will be reclaimed after it is no longer required for natural gas production. c. Impacts on Wildlife and domestic animals through creation of hazardous attractions, alteration of existing native vegetation, blockade of migration routes, use patterns, or other disruptions The proposed storage area will not create hazardous attractions or alter existing native vegetation. The proposal will not block wildlife migration routes or use patterns. d. Evaluation of any potential radiation hazard that may have been identified by the State or County Health Departments The proposed site is not located on or near a Uranium Mine Tailings Radiation Control Act (UMTRCA) Site or other known radiation hazard site. Radon is a naturally occurring, odorless and colorless radioactive gas that is produced by the radioactive decay of radioactive minerals present in the soils and bedrock. According to the Colorado Department of Public Health and Environment (CDPHE), Colorado has a moderate to high radon potential. Since the site is a facility that does not have buildings or an area that is occupied throughout the work day, the potential presence of radon is not expected to represent a geologic hazard or a significant worker exposure issue. 9. Nuisance Adjacent lands will not be impacted by the generation of vapor, dust, smoke, glare or vibration. In accordance with Oxy's Fugitive Dust Mitigation Plan, water will be used for Impact Analysis Page 7 OXY USA WTP LP Pond G Facility dust suppression during construction and operation of the facility. Any lighting on-site will be down cast. 10. Hours of Operation The Pond G facility will be accessible to Oxy personnel 24 hours a day, year around. No personnel will be stationed at the facility on a regular basis.

This facility will be used to store produced water that would be recycled for well completions or eventually disposed of at a permitted facility. The facility is currently constructed as a production pond and OXY is requesting approval as an E & P facility. It is expected that the lifespan of the site will be approximately 30 years. The site is located approximately 24 travel miles north of the Exit 62 interchange of Highway I- 70 at DeBeque, Colorado. The facility is located in the Southeast 1/4 of the Northwest 1/4 of Section 16, Township 6 South, Range 97 West of the 6th Principal Meridian in unincorporated Garfield County. The subject site encompasses approximately 14.88 acres on a 7,732.52 acre parcel and is located at an elevation of 8,300 feet. The property is owned by and the facility is operated by Oxy. The objective of this analysis is to review the existing road network, provide traffic projections for the facility, determine trip distribution, and analyze the need for roadway modifications. EXISTING ROAD NETWORK This facility will be accessed from the 1-70 exit at DeBeque, Colorado. Vehicles traveling to the site will drive north through the Town of DeBeque and on Mesa County 45 Road (Roan Creek Road) for approximately 3.75 miles. The road continues and crosses the Garfield/Mesa County Line where the road transitions to Garfield County Road (CR) 204. Approximately 4.25 miles north of the county line vehicles will turn right onto CR 213 (Conn Creek Road) and travel approximately 4 miles to the end of the county road. From this point travel is on a series of private roads that were built and are maintained for the exclusive use of the natural gas industry. The facility is located an additional 12 miles up Cascade Creek and on the top of the Plateau. Both CR 204 and 213 are preferred haul routes according to maps available on the Garfield County web -site. Both of these roads are generally used for access to ranches and agricultural operations, rural residential uses, oil and gas operations and access to public lands managed by the BLM. According to the Garfield County Road Inventory Report, CR 204 is classified as Local road and is a two lane asphalt roadway with gravel shoulders. The 2011 Garfield County HUTF Report OXY Pond G Complex 1 April, 2013 Basic Traffic Analysis describes the roadway as is in good condition. The road has a posted speed limit of 45 mph. During 2002, Garfield County Road & Bridge conducted a traffic study of CR 204. The study concluded that there were 337 average trips per day (ADT) at that time. According to the Garfield County Road Inventory Report, CR 213 is classified as Local road and is a two lane road consisting of a section constructed of a combination of soil, gravel, and stone and a section consisting of graded and drained natural soil. The 2011 Garfield County HUTF Report describes the roadway as is in good condition. During 2002, Garfield County Road & Bridge conducted a traffic study for CR 213. The study concluded that there were 9 average trips per day at that time. There is a deceleration/turn lane for north bound traffic on CR 204 turning right onto CR 213. A stop sign controls west bound traffic on CR 213 at the intersection of that road with CR204. TRAFFIC PROJECTIONS Given the lack of data regarding traffic growth for this area, a conservative growth rate of 3% is assumed. This rate was applied to the existing counts to obtain background traffic for the forecast years of 2013 and 2043, respectively. These planning horizon years were chosen as they correspond with the expected life of the facility. This results in an estimated ADT of 446 in 2013 and a projected ADT of 1132 in 2043 for CR 204. The result for CR 213 in 2013 is an estimated ADT of 12 and a projected ADT of 30 in 2043 (Table 1). Table 1: Background Traffic Projections — Pond G Facility TRIP GENERATION AND DISTRIBUTION Trip generation is generally determined using rates found in the ITE Trip Generation manual. Rates from this publication are applied to values related to the size of the proposed site to estimate the trips expected to enter and exit the site. In this case, no rates are provided for facilities similar to these. To estimate trips expected for this site, information was gathered regarding the expected traffic based on the existing operations. Vehicle activities during daily operations will consist of one (1) pickup truck per day and one (1) transport truck every day.

Oxy Pond G Complex 2 April, 2013 Basic Traffic Analysis One (1) additional pickup truck and one (1) additional transport truck will be used for maintenance purposes each quarter. Trip generation will increase by three (3) pickup trucks and two (2) transport trucks per day and one (1) additional pickup truck and one (1) additional transport each month during periods of drilling and completion. Drilling and completion activities will occur periodically throughout the life of the project. The following Table 2 summarizes the expected average and maximum trips for the operational life of the facility.

Additionally, the majority of traffic on this road is currently associated with the natural gas industry and the general public will not be impacted by the increase of traffic on this road. CONSTRUCTION PHASE The storage pond is currently built, and major excavation of the site will not be necessary. Only minor construction traffic will be generated by this project to bring the facility up to COGCC E&P Waste Management Facility standards. ROADWAY ANALYSIS Existing Parcel Current land use on the subject parcel is primarily natural gas development. The majority of existing traffic on CR 213 is related to natural gas development activities, very limited agricultural activities and very low density rural residential uses. State Highway Crossings and Access The roadway access to this site does not cross any highway right-of-ways managed by the Colorado Department of Transportation. CR 204 is accessed via Mesa County 45 Road which accesses the State of Colorado highway system at the 1-70, Exit 62, interchange at DeBeque, Colorado. This grade separated interchange access point is controlled by stop signs at the top of each exit ramp. Site distances are adequate in both directions at these control points. Additional traffic control is not needed at this location. US Highway 6 / 1-70 Frontage Road terminates at Mesa County 45 Road approximately 300 feet northwest of the DeBeque interchange. This intersection is controlled with a combination of stop Oxy Pond G Complex 4 April, 2013 Basic Traffic Analysis and yield signage on the state highway leg of the intersection. Traffic traveling to this site from 1-70 would have the right-of-way at this intersection. Additional improvements are not needed at this location. Railroad Crossings Mesa County 45 Road crosses under a main railroad line approximately 0.5 miles north of the 1-70. This line is generally used for the transport of freight, coal and passenger rail traffic. This railroad crossing is grade separated and warning signals are not present or warranted. The roadway access to this site does not cross any other active railroad right-of-ways. Additional improvements are not needed at this location. Intersection of CR 204 & 213 As noted above, there is a deceleration/turn lane for north bound traffic on CR 204 turning right onto CR 213. A stop sign controls west bound traffic on CR 213 at the intersection of that road with CR 204. Given the amount of traffic estimated to be generated from the proposed facility additional improvements at this intersection are not needed at this time. RECOMMENDATIONS Based on the expected trip generation rates discussed above, the increase in average daily traffic is not expected to be significant on roads generally used by the public. CR 204 will see only a minor increase in traffic. CR 213 will see a significant increase in traffic only because of a very low baseline of traffic volume. However, the total traffic volumes will remain very low and can be accommodated by the existing roadway. Additionally, the majority of traffic on this road is associated with the natural gas industry. The worst-case scenario is that there would be a minor increase in traffic which would peak during drilling and completion activities. Based on the results of the analysis, no mitigation is recommended for the facility. As mentioned in the Roadway Analysis, the addition of traffic generated by the proposed facility does not increase existing volumes to levels required for auxiliary lanes or other roadway modifications.

WILDLIFE HABITAT AREAS Oxy commissioned ERO Resources Corporation (ERO) to prepare a biological resources survey of the site and it is included as an attachment to this application. A. Buffers Visual or sound buffers are not necessary to screen structures or activity areas from habitat areas. The facility will be fenced with an eight -foot tall wildlife fence, and the pond will be netted to exclude water fowl from the facility. According to a Biological Resources Survey performed by ERO, the site has the potential for only one federally threatened, proposed and candidate species to occur in the project area. ERO surveyed the project site for the potential habitat for the greater sage grouse. They found the area to be poor habitat for the greater sage grouse. This conclusion corresponds with the Suitable Habitat Results map of the adopted Garfield County Greater Sage -Grouse Conservation Plan. B. Locational Controls of Land Disturbance The project area is currently disturbed after being previously developed as a production pond. No additional wildlife habitat disturbance will occur. According to the ERO survey, most wildlife species that are likely to occur in the project boundaries are adapted to human - caused disturbance. The conversion of the site to an E & P Waste Management facility should not alter current migration patterns. Standards Analysis Page 3 OXY USA WTP LP Pond G Facility C. Preservation of Native Vegetation The site will be reclaimed after the facility is no longer utilized and will be revegetated with native plant species. Noxious weeds will be controlled during the life of the facility and during the re-establishment of native plants. A Noxious Weed Management Plan specifically developed for this site is included with this application in the Grading and Drainage Plan section. D. Habitat Compensation No critical wildlife habitat will be disturbed in converting this site to an E & P facility. E. Domestic Animal Controls Domestic animals will not be kept on the site.

They highlight soil limitations that affect various land uses and provide information about the properties of the soils in the survey areas. Soil surveys are designed for many different users, including farmers, ranchers, foresters, agronomists, urban planners, community officials, engineers, developers, builders, and home buyers. Also, conservationists, teachers, students, and specialists in recreation, waste disposal, and pollution control can use the surveys to help them understand, protect, or enhance the environment. Various land use regulations of Federal, State, and local governments may impose special restrictions on land use or land treatment. Soil surveys identify soil properties that are used in making various land use or land treatment decisions. The information is intended to help the land users identify and reduce the effects of soil limitations on various land uses. The landowner or user is responsible for identifying and complying with existing laws and regulations. Although soil survey information can be used for general farm, local, and wider area planning, onsite investigation is needed to supplement this information in some cases. Examples include soil quality assessments (http://soils.usda.gov/sqi/) and certain conservation and engineering applications. For more detailed information, contact your local USDA Service Center (http://offices.sc.egov.usda.gov/locator/app? agency=nrcs) or your NRCS State Soil Scientist (http://soils.usda.gov/contact/ state_offices/). Great differences in soil properties can occur within short distances. Some soils are seasonally wet or subject to flooding. Some are too unstable to be used as a foundation for buildings or roads. Clayey or wet soils are poorly suited to use as septic tank absorption fields. A high water table makes a soil poorly suited to basements or underground installations. The National Cooperative Soil Survey is a joint effort of the United States Department of Agriculture and other Federal agencies, State agencies including the Agricultural Experiment Stations, and local agencies. The Natural Resources Conservation Service (NRCS) has leadership for the Federal part of the National Cooperative Soil Survey. Information about soils is updated periodically. Updated information is available through the NRCS Soil Data Mart Web site or the NRCS Web Soil Survey. The Soil Data Mart is the data storage site for the official soil survey information.

They include a description of the soils and miscellaneous areas and their location on the landscape and tables that show soil properties and limitations affecting various uses. Soil scientists observed the steepness, length, and shape of the slopes; the general pattern of drainage; the kinds of crops and native plants; and the kinds of bedrock. They observed and described many soil profiles. A soil profile is the sequence of natural layers, or horizons, in a soil. The profile extends from the surface down into the unconsolidated material in which the soil formed or from the surface down to bedrock. The unconsolidated material is devoid of roots and other living organisms and has not been changed by other biological activity. Currently, soils are mapped according to the boundaries of major land resource areas (MLRAs). MLRAs are geographically associated land resource units that share common characteristics related to physiography, geology, climate, water resources, soils, biological resources, and land uses (USDA, 2006). Soil survey areas typically consist of parts of one or more MLRA. The soils and miscellaneous areas in a survey area occur in an orderly pattern that is related to the geology, landforms, relief, climate, and natural vegetation of the area. Each kind of soil and miscellaneous area is associated with a particular kind of landform or with a segment of the landform. By observing the soils and miscellaneous areas in the survey area and relating their position to specific segments of the landform, a soil scientist develops a concept, or model, of how they were formed. Thus, during mapping, this model enables the soil scientist to predict with a considerable degree of accuracy the kind of soil or miscellaneous area at a specific location on the landscape. Commonly, individual soils on the landscape merge into one another as their characteristics gradually change. To construct an accurate soil map, however, soil scientists must determine the boundaries between the soils. They can observe only a limited number of soil profiles. Nevertheless, these observations, supplemented by an understanding of the soil -vegetation -landscape relationship, are sufficient to verify predictions of the kinds of soil in an area and to determine the boundaries. Soil scientists recorded the characteristics of the soil profiles that they studied. They noted soil color, texture, size and shape of soil aggregates, kind and amount of rock fragments, distribution of plant roots, reaction, and other features that enable them to identify soils. After describing the soils in the survey area and determining their properties, the soil scientists assigned the soils to taxonomic classes (units). Taxonomic classes are concepts. Each taxonomic class has a set of soil characteristics with precisely defined limits. The classes are used as a basis for comparison to classify soils systematically. Soil taxonomy, the system of taxonomic classification used in the United States, is based mainly on the kind and character of soil properties and the arrangement of horizons within the profile. After the soil scientists classified and named the soils in the survey area, they compared the 5 Custom Soil Resource Report individual soils with similar soils in the same taxonomic class in other areas so that they could confirm data and assemble additional data based on experience and research. The objective of soil mapping is not to delineate pure map unit components; the objective is to separate the landscape into landforms or landform segments that have similar use and management requirements. Each map unit is defined by a unique combination of soil components and/or miscellaneous areas in predictable proportions. Some components may be highly contrasting to the other components of the map unit. The presence of minor components in a map unit in no way diminishes the usefulness or accuracy of the data. The delineation of such landforms and landform segments on the map provides sufficient information for the development of resource plans. If intensive use of small areas is planned, onsite investigation is needed to define and locate the soils and miscellaneous areas. Soil scientists make many field observations in the process of producing a soil map. The frequency of observation is dependent upon several factors, including scale of mapping, intensity of mapping, design of map units, complexity of the landscape, and experience of the soil scientist. Observations are made to test and refine the soil - landscape model and predictions and to verify the classification of the soils at specific locations. Once the soil -landscape model is refined, a significantly smaller number of measurements of individual soil properties are made and recorded. These measurements may include field measurements, such as those for color, depth to bedrock, and texture, and laboratory measurements, such as those for content of sand, silt, clay, salt, and other components. Properties of each soil typically vary from one point to another across the landscape. Observations for map unit components are aggregated to develop ranges of characteristics for the components. The aggregated values are presented. Direct measurements do not exist for every property presented for every map unit component. Values for some properties are estimated from combinations of other properties. While a soil survey is in progress, samples of some of the soils in the area generally are collected for laboratory analyses and for engineering tests. Soil scientists interpret the data from these analyses and tests as well as the field -observed characteristics and the soil properties to determine the expected behavior of the soils under different uses. Interpretations for all of the soils are field tested through observation of the soils in different uses and under different levels of management. Some interpretations are modified to fit local conditions, and some new interpretations are developed to meet local needs. Data are assembled from other sources, such as research information, production records, and field experience of specialists. For example, data on crop yields under defined levels of management are assembled from farm records and from field or plot experiments on the same kinds of soil. Predictions about soil behavior are based not only on soil properties but also on such variables as climate and biological activity. Soil conditions are predictable over long periods of time, but they are not predictable from year to year. For example, soil scientists can predict with a fairly high degree of accuracy that a given soil will have a high water table within certain depths in most years, but they cannot predict that a high water table will always be at a specific level in the soil on a specific date. After soil scientists located and identified the significant natural bodies of soil in the survey area, they drew the boundaries of these bodies on aerial photographs and identified each as a specific map unit. Aerial photographs show trees, buildings, fields, roads, and rivers, all of which help in locating boundaries accurately. 6 Soil Map The soil map section includes the soil map for the defined area of interest, a list of soil map units on the map and extent of each map unit, and cartographic symbols displayed on the map. Also presented are various metadata about data used to produce the map, and a description of each soil map unit. 7 39° 31' 40" 39° 31' 26" Custom Soil Resource Report Soil Map 108° 13' 36" 108° 13' 50" Map Scale: 1:1,980 if printed on Asize (8.5" x 11") sheet.

The map unit descriptions, along with the maps, can be used to determine the composition and properties of a unit. A map unit delineation on a soil map represents an area dominated by one or more major kinds of soil or miscellaneous areas. A map unit is identified and named according to the taxonomic classification of the dominant soils. Within a taxonomic class there are precisely defined limits for the properties of the soils. On the landscape, however, the soils are natural phenomena, and they have the characteristic variability of all natural phenomena. Thus, the range of some observed properties may extend beyond the limits defined for a taxonomic class. Areas of soils of a single taxonomic class rarely, if ever, can be mapped without including areas of other taxonomic classes. Consequently, every map unit is made up of the soils or miscellaneous areas for which it is named and some minor components that belong to taxonomic classes other than those of the major soils. Most minor soils have properties similar to those of the dominant soil or soils in the map unit, and thus they do not affect use and management. These are called noncontrasting, or similar, components. They may or may not be mentioned in a particular map unit description. Other minor components, however, have properties and behavioral characteristics divergent enough to affect use or to require different management. These are called contrasting, or dissimilar, components. They generally are in small areas and could not be mapped separately because of the scale used. Some small areas of strongly contrasting soils or miscellaneous areas are identified by a special symbol on the maps. If included in the database for a given area, the contrasting minor components are identified in the map unit descriptions along with some characteristics of each. A few areas of minor components may not have been observed, and consequently they are not mentioned in the descriptions, especially where the pattern was so complex that it was impractical to make enough observations to identify all the soils and miscellaneous areas on the landscape. The presence of minor components in a map unit in no way diminishes the usefulness or accuracy of the data. The objective of mapping is not to delineate pure taxonomic classes but rather to separate the landscape into landforms or landform segments that have similar use and management requirements. The delineation of such segments on the map provides sufficient information for the development of resource plans. If intensive use of small areas is planned, however, onsite investigation is needed to define and locate the soils and miscellaneous areas. 10 Custom Soil Resource Report An identifying symbol precedes the map unit name in the map unit descriptions. Each description includes general facts about the unit and gives important soil properties and qualities. Soils that have profiles that are almost alike make up a soil series. Except for differences in texture of the surface layer, all the soils of a series have major horizons that are similar in composition, thickness, and arrangement. Soils of one series can differ in texture of the surface layer, slope, stoniness, salinity, degree of erosion, and other characteristics that affect their use. On the basis of such differences, a soil series is divided into soil phases. Most of the areas shown on the detailed soil maps are phases of soil series. The name of a soil phase commonly indicates a feature that affects use or management. For example, Alpha silt loam, 0 to 2 percent slopes, is a phase of the Alpha series. Some map units are made up of two or more major soils or miscellaneous areas. These map units are complexes, associations, or undifferentiated groups. A complex consists of two or more soils or miscellaneous areas in such an intricate pattern or in such small areas that they cannot be shown separately on the maps. The pattern and proportion of the soils or miscellaneous areas are somewhat similar in all areas. Alpha -Beta complex, 0 to 6 percent slopes, is an example. An association is made up of two or more geographically associated soils or miscellaneous areas that are shown as one unit on the maps. Because of present or anticipated uses of the map units in the survey area, it was not considered practical or necessary to map the soils or miscellaneous areas separately. The pattern and relative proportion of the soils or miscellaneous areas are somewhat similar. Alpha - Beta association, 0 to 2 percent slopes, is an example. An undifferentiated group is made up of two or more soils or miscellaneous areas that could be mapped individually but are mapped as one unit because similar interpretations can be made for use and management. The pattern and proportion of the soils or miscellaneous areas in a mapped area are not uniform. An area can be made up of only one of the major soils or miscellaneous areas, or it can be made up of all of them. Alpha and Beta soils, 0 to 2 percent slopes, is an example. Some surveys include miscellaneous areas. Such areas have little or no soil material and support little or no vegetation. Rock outcrop is an example. 11 Custom Soil Resource Report Douglas -Plateau Area, Colorado, Parts of Garfield and Mesa Counties 52—Northwater-Adel complex, 5 to 50 percent slopes Map Unit Setting

displayed as thematic maps with a summary table for the soil map units in the selected area of interest. A single value or rating for each map unit is generated by aggregating the interpretive ratings of individual map unit components. This aggregation process is defined for each interpretation. Building Site Development Building site development interpretations are designed to be used as tools for evaluating soil suitability and identifying soil limitations for various construction purposes. As part of the interpretation process, the rating applies to each soil in its described condition and does not consider present land use. Example interpretations can include corrosion of concrete and steel, shallow excavations, dwellings with and without basements, small commercial buildings, local roads and streets, and lawns and landscaping. Corrosion of Steel "Risk of corrosion" pertains to potential soil -induced electrochemical or chemical action that corrodes or weakens uncoated steel. The rate of corrosion of uncoated steel is related to such factors as soil moisture, particle -size distribution, acidity, and electrical conductivity of the soil. Special site examination and design may be needed if the combination of factors results in a severe hazard of corrosion. The steel in installations that intersect soil boundaries or soil layers is more susceptible to corrosion than the steel in installations that are entirely within one kind of soil or within one soil layer. The risk of corrosion is expressed as "low," "moderate," or "high." 15 39° 31' 40" 39° 31' 26" 738050 738100 Custom Soil Resource Report Map—Corrosion of Steel 738150 738200 738250 738300 738350 o 0 0 0 o O s- .rn CO M O 0 N 0) OD rn —co00— M r CO a V O o O O O o, coco V V O O LO LO OJ OJ M. .oJ r C -- OD M CO m- d OD 71 - CO CJ OJT CO 0) 738050 108° 13'50" 738100 738150 738200 Map Scale: 1:1,980 if printed on Asize (8.5" x 11") sheet.

A map unit is typically composed of one or more "components". A component is either some type of soil or some nonsoil entity, e.g., rock outcrop. For the attribute being aggregated, the first step of the aggregation process is to derive one attribute value for each of a map unit's components. From this set of component attributes, the next step of the aggregation process derives a single value that represents the map unit as a whole. Once a single value for each map unit is derived, a thematic map for soil map units can be rendered. Aggregation must be done because, on any soil map, map units are delineated but components are not. For each of a map unit's components, a corresponding percent composition is recorded. A percent composition of 60 indicates that the corresponding component typically makes up approximately 60% of the map unit. Percent composition is a critical factor in some, but not all, aggregation methods. The aggregation method "Dominant Condition" first groups like attribute values for the components in a map unit. For each group, percent composition is set to the sum of the percent composition of all components participating in that group. These groups now represent "conditions" rather than components. The attribute value associated with the group with the highest cumulative percent composition is returned. If more than one group shares the highest cumulative percent composition, the corresponding "tie-break" rule determines which value should be returned. The "tie-break" rule indicates whether the lower or higher group value should be returned in the case of a percent composition tie. The result returned by this aggregation method represents the dominant condition throughout the map unit only when no tie has occurred. Component Percent Cutoff: None Specified Components whose percent composition is below the cutoff value will not be considered. If no cutoff value is specified, all components in the database will be considered. The data for some contrasting soils of minor extent may not be in the database, and therefore are not considered. 18 Custom Soil Resource Report Tie-break Rule: Higher The tie-break rule indicates which value should be selected from a set of multiple candidate values, or which value should be selected in the event of a percent composition tie. Corrosion of Concrete "Risk of corrosion" pertains to potential soil -induced electrochemical or chemical action that corrodes or weakens concrete. The rate of corrosion of concrete is based mainly on the sulfate and sodium content, texture, moisture content, and acidity of the soil. Special site examination and design may be needed if the combination of factors results in a severe hazard of corrosion. The concrete in installations that intersect soil boundaries or soil layers is more susceptible to corrosion than the concrete in installations that are entirely within one kind of soil or within one soil layer. The risk of corrosion is expressed as "low," "moderate," or "high." 19 Custom Soil Resource Report MAP LEGEND MAP INFORMATION Area of Interest (AOI) Map Scale: 1:1,980 if printed on A size (8.5" x 11") sheet.

Water Features Water Features include ponding frequency, flooding frequency, and depth to water table. Flooding Frequency Class Flooding is the temporary inundation of an area caused by overflowing streams, by runoff from adjacent slopes, or by tides. Water standing for short periods after rainfall or snowmelt is not considered flooding, and water standing in swamps and marshes is considered ponding rather than flooding. Frequency is expressed as none, very rare, rare, occasional, frequent, and very frequent. "None" means that flooding is not probable. The chance of flooding is nearly 0 percent in any year.

A map unit is typically composed of one or more "components". A component is either some type of soil or some nonsoil entity, e.g., rock outcrop. For the attribute being aggregated, the first step of the aggregation process is to derive one attribute value for each of a map unit's components. From this set of component attributes, the next step of the aggregation process derives a single value that represents the map unit as a whole. Once a single value for each map unit is derived, a thematic map for soil map units can be rendered. Aggregation must be done because, on any soil map, map units are delineated but components are not. For each of a map unit's components, a corresponding percent composition is recorded. A percent composition of 60 indicates that the corresponding component typically makes up approximately 60% of the map unit. Percent composition is a critical factor in some, but not all, aggregation methods. The aggregation method "Dominant Condition" first groups like attribute values for the components in a map unit. For each group, percent composition is set to the sum of the percent composition of all components participating in that group. These groups now represent "conditions" rather than components. The attribute value associated with the group with the highest cumulative percent composition is returned. If more than one group shares the highest cumulative percent composition, the corresponding "tie-break" rule determines which value should be returned. The "tie-break" rule indicates whether the lower or higher group value should be returned in the case of a percent composition tie. The result returned by this aggregation method represents the dominant condition throughout the map unit only when no tie has occurred. Component Percent Cutoff: None Specified Components whose percent composition is below the cutoff value will not be considered. If no cutoff value is specified, all components in the database will be considered. The data for some contrasting soils of minor extent may not be in the database, and therefore are not considered. 27 Custom Soil Resource Report Tie-break Rule: More Frequent The tie-break rule indicates which value should be selected from a set of multiple candidate values, or which value should be selected in the event of a percent composition tie.

According to Article 4: Application and Review Procedures 4-203 Description of Submittal Requirements A. Professional Qualifications The professional qualifications for preparation and certification of certain documents is required by the Garfield County LUDC, and require that "Geology reports shall be prepared by either a member of the American Institute of Professional Geologists, a member of the Association of Engineering Geologists, or a qualified geotechnical engineer licensed in the state of Colorado." Garfield County LUDC 2013 Article 7-207 requires an assessment of Natural and Geologic Hazards as part of the SUP submittal. Garfield County defines a geologic hazard as "A geologic phenomenon that is so adverse to past, current, or foreseeable construction or land use as to constitute a significant hazard to public health and safety or to property." This term includes, but is not limited to avalanches, landslides, rock falls, mudflows, unstable or potentially unstable soils, seismic effects, radioactivity, and ground subsidence. This summary presents an assessment of geologic hazards potentially present in the vicinity of the OXY Pond G centralized E&P Waste Management Facility. Currently the state of Colorado does not require licensure or registration of geologists. However, Colorado Revised Statutes do require that geologic reports be prepared or authorized by a professional geologist. Professional Geologist is a term defined in Colorado Statutes. The references for these laws are shown here: 34-1-201. Definitions. As used in this part 2, unless the context otherwise requires: (1) "Geologist" means a person engaged in the practice of geology. (2) "Geology" means the science which treats of the earth in general; the earth's processes and its history; investigation of the earth's crust and the rocks and other materials which compose it; and the applied science of utilizing knowledge of the earth's history, processes, constituent rocks, minerals, liquids, gases, and other materials for the use of mankind. (3) "Professional geologist" is a person who is a graduate of an institution of higher education which is accredited by a regional or national accrediting agency, with a minimum of thirty semester hours (forty-five quarter) hours of undergraduate or graduate work in a field of geology and whose post baccalaureate training has been in the field of geology with a specific record of an additional five years of geological experience to include no more than two years of graduate work. (4) 34-1-202. Reports containing geologic information. Any report required by law or by rule and regulation, and prepared as a result of or based on a geologic study or on geologic data, or which contains information relating to geology, as defined in section 34-1-201 (2), and which is to be presented for any state agency, political subdivision of the state, or recognized state or local board or commission, shall be prepared or approved by a professional geologist as defined in section 34-1-201(3). Professional Geologist Certification By means of this certification, I attest that: - Although the Colorado Geological Survey does not currently have a licensing or registration program for professional geologists practicing in the state of Colorado, there are requirements within local and State statutes that require that geologic reports be prepared by a professional geologist. I attest that I meet the requirements of the Colorado Geological Survey's definition of a professional geologist having completed and met the educational requirements of the Colorado Geological Survey definition; - I am qualified to prepare a Natural and Geologic Hazard Summary in accordance with the provisions of Garfield County Colorado LUDC 2013; - I have reviewed published geologic reports and geologic maps prepared by the CGS and United States Geologic Survey (USGS), and others related to geologic conditions or hazards potentially present in the project area; - The conclusions and recommendations contained in this report are based on information available and known to me at the time of this report. Good scientific principles and standard engineering practices were taken into consideration in arriving at the conclusions and recommendations made in this report. James W. Hix Senior Geologist Date: 08/01/2013 Note: The PG's certification does not relieve the owner/operator of the facility of the duty of fully implementing the recommendations in accordance with all applicable Federal, State, and local requirements in order to achieve the desired goals or objectives. Form 28 - Centralized E&P Waste Management Facility Permit Application for COGCC ID #414402 Oxy Pond G Centralized E&P Waste Management Facility SE NW Section 16, T6S, R97W, 6th P.M., Garfield County, Colorado Rule 908.b (4) Topography The Oxy Pond G Centralized E&P Waste Management Facility consists of adjacent ponds that are being permitted as one facility. The site is shown on the U.S.G.S. Circle Dot Gulch 7.5 - minute topographic map. The facility is located near the rim of Cascade Canyon approximately 15 miles north of the town of De Beque in western Garfield County, Colorado. The site is located near the center of the Piceance Basin, an elongated, irregularly- shaped structural depression in the earth's crust resulting from tectonic forces associated with the uplift of the Rocky Mountains through geologic time. The general terrain surrounding the facility consists of rugged canyons incised into the Roan Cliffs. The present topography is the result of uplift combined with stream erosion. The erosion produced a series of high plateaus and deep valleys associated with the down cutting of Colorado River located to the south. The site is located approximately 550 feet northwest of an unnamed drainage to Cascade Canyon. The site lies at an elevation of approximately 8,260 feet above mean sea level. The elevation of Cascade Creek lies at more than 1,000 feet below the site elevation. Soils (Rule 908.b (7).A.i) The proposed facility is underlain by soils mapped by the U.S. Natural Resources Conservation Service as the Parachute — Rhone loams, which are found on mountain sides and on ridge crests with 5 percent to 30 percent slopes, at elevations of 7,600 feet to 8,800 feet above mean sea level. The unit is about 55 percent Parachute soil and 35 percent Rhone loam. The two soils occur as areas so intricately intermingled that mapping them separately was deemed impractical at the scale used in the soil survey. Please refer to the Pond G Complex Soils Map. The Parachute soil is moderately deep and is well drained. It formed in residuum derived dominantly from sandstone, siltstone, and shale. Typically the surface layer consists of grayish brown loam and is about ten inches thick; while the subsoil is brown very channery loam about 15 inches thick, with rippable, fractured siltstone encountered at depths of about 25 inches. Permeability is moderate in the Parachute soil, and the available water capacity is very low. Runoff is medium or rapid, and the hazard of water erosion is moderate to very severe. The Rhone loam is deep and well drained and is formed in residuum and colluvium derived from predominantly from sandstone or shale. Typically the surface layer is brown channery loam about six inches thick, the subsoil is very dark grayish brown loam about 10 inches thick, and Geohydrology Report Page 1 the next layer is a dark grayish brown channery loam about 29 inches thick, and the subsoil is brown very channery loam about 16 inches thick. Rippable, fractured siltstone is encountered at depths of about 55 inches. Permeability of the Rhone loam soils is moderate and the available water capacity is also moderate. Runoff is medium or rapid, and the hazard of water erosion is moderate to very severe. Bedrock Geology (Rule 908.b (7).A.ii) The bedrock underlying the proposed facility is composed of the Tertiary age Uinta Formation or the Parachute Creek Member of the Green River Formation. The Uinta Formation consists of permeable, poorly sorted, fine to coarse sandstone with some siltstone and mudstone, becoming more coarse-grained and permeable toward the top of the formation. The Uinta Formation and the Parachute Member of the upper part of the Green River Formation comprise the Uinta — Animas aquifer in the Piceance Basin. Please refer to the Pond G Complex Geology Map. The Uinta Formation lies stratigraphically above the Tertiary age Parachute Member of the Green River Formation. The Parachute Creek Member consists primarily of dolomitic marlstone. Kerogen, a waxlike hydrocarbon, is present in some parts of the Parachute Creek Member in the Piceance and Uinta Basins. Marlstone containing large concentrations of kerogen is referred to as "oil shale" and is generally not as fractured and contains smaller concentrations of kerogen. Fractures and dissolution openings along fractures in the marlstone form the principal pathways for water movement in the aquifer (Robson and Banta, 1995). Oil shale is generally less permeable and forms confining units. The Mahogany zone is an oil shale bed within the Parachute Creek Member that is an example of a confining unit found within the Piceance Basin. A saline zone in the lower marlstone of the Parachute Creek Member is found within the central part of the Piceance Basin and contains the minerals nahcolite and halite, is not extensively fractured, and forms part of the relatively impermeable lower confining unit of the aquifer (Robson and Banta, 1995). The depth to the top of the Mahogany zone in the vicinity of the site is expected to lie at an elevation of 6,000 feet. The Garden Gulch Member, Anvil Points Member, and Douglas Creek Member of the Green River Formation and the Tertiary age Wasatch Formation forms a confining unit that separates the Uinta — Animas aquifer from the underlying upper Cretaceous Mesaverde aquifer. Local and Regional Geologic Structures (Rule 908.b (7).A.iii) The Pond G facility is located on the southwestern limb of the Crystal Creek Anticline and the northeastern limb of the Clear Creek Syncline. The northwest trending fold system of the Crystal Creek anticlinal nose and the Clear Creek Syncline begins near the Colorado River and extends northward for approximately 30 miles into the southwestern part of the Piceance Creek Basin. A part of the Clear Creek syncline occupies the southwestern part of this area and the trace of its axis is closely parallel to that of the Crystal Creek anticline. The Clear Creek syncline is a broad shallow fold the trace of which closely parallels the axis of the Crystal Creek Geohydrology Report Page 2 anticline. The Crystal Creek anticlinal nose forms the southeastern element of an anticlinal fold that trends across the southwest part of the Piceance Basin. The fold plunges to the northwest and terminates near the western boundary of the area in a structural saddle (Hail, 1992). The anticline is somewhat asymmetrical and has steeper dips on its southwest limb of about 200 feet per mile and gentler dips on its northeastern limb of about 65 feet per mile (Hail, 1992). No major faults are present in the project area. Two small groups of normal faults are present in the southern extent of the Roan Plateau with one set approximately 15 miles northeast and a second smaller group about 20 miles northwest of the project site (Hail, 1992). Geologic Hazards (Rule 908.b (7).A.i) There are no major faults in the central Roan Plateau area (Hail, 1992). Minimal seismic activity near the proposed disposal facility has occurred in recent geologic time. One earthquake of magnitude greater than 5.0 occurred in Garfield County since the early 1960s when proper instrumentation was implemented in the state of Colorado. The epicenter of this earthquake was approximately 17 miles southeast of the project site. A second recorded earthquake greater than 5.0 occurred in Rio Blanco County with an epicenter about 20 miles northwest of the project site. Mesa County has historically experienced few earthquakes. The USGS has rated Mesa County as having low to moderate earthquake hazard, although no specific seismic study has been done in Mesa County. According to the Colorado Geological Survey, no Quaternary -age faults are present in the Roan Plateau area (Widmann and others, 1998). However, the Geologic Map of Colorado (Tweto, 1979) shows northeast -southwest trending normal faults exist in the Cretaceous bedrock near the Douglas Creek Arch and the western edge of the Piceance Basin. In addition, a series of normal faults trace along the eastern Piceance Basin boundary near the Grand Hogback to the east. Although faults are not always visible at the surface, this does not preclude the chance of an earthquake happening in the area at some point in the future. According to the Colorado Earthquake Hazard Mitigation Council (2008), "Earthquakes can also occur on faults that do not rupture the ground surface or on faults that are not yet recognized as being hazardous. These so called "random" earthquakes are considered in most hazard analyses to help account for faults that are not apparent at the earth's surface." No surficial geologic hazards (landslide, mudflow, fan) or soils hazards have been mapped in the immediate vicinity of the proposed facility. The site is not located in an area mapped as a floodplain hazard by the Federal Emergency Management Agency (FEMA). However, because of the natural slope above the property within the northeast -to -southwest oriented drainage, overland flow is possible in the event of an extreme precipitation event. Although records of extreme rainfall events are unavailable for locations on top of the Roan Plateau, climate records since the mid -20th century indicate that the record 24-hour rainfall amounts at Grand Junction, Palisade, and Parachute have not exceeded 2 inches (Western Regional Climate Center, 2011). The duration of these events within a 24 hour period is not known, and it is possible that a short Geohydrology Report Page 3 burst of intense rainfall event could cause local overland flow in the watershed that encompasses the project site if a precipitation rate exceeds the infiltration rate of the watershed soils. The primary limitations for shallow excavations are based on the slopes and severe seepage. Consideration will be given to the design and construction of this facility to ensure that slopes are graded appropriately to minimize the potential for cutback caving. The suitability of the soils in the project area is identified as being somewhat to very limited in regard to the construction of ponds and embankments. The limitations identified are primarily applicable to unlined water impoundments. Consideration will be given to design and construction characteristics related to the area soil thickness and depth to bedrock to mitigate these limitations. Consideration will also be given to the design and operation of the high density polyethylene (HDPE) liner system for the impoundments, which will mitigate potential seepage and leaks. Surface Water Features (Rule 908.b (7).B.i) Surface water features within two miles of the project site include Cascade Canyon located approximately 1,660 feet to the southeast of the water treatment facility, and an unnamed tributary drainage to Cascade Canyon located approximately 550 feet to the southwest. The site lies on a drainage divide between Cascade Creek to the east and Conn Creek to the west - northwest. If a produced water spill were to occur and leave the site, it is expected that it would flow toward Cascade Canyon. Please refer to the Pond G Complex Surface Water Map. The site is shown on the USGS 1:24,000 topographic map (Circle Dot Gulch Quadrangle). Cascade Creek has perennial flow, although no flow records are available to determine the flow conditions in these drainages. There are no springs shown in Section 16, Township 6 South, Range 97 West. Shallow Groundwater and Major Aquifers (Rule 908.b (7).B.ii) Shallow groundwater is not expected to occur in close proximity to the site due to the site being located on a prominence of Cascade Canyon at an elevation of approximately 8,400 feet. Cascade Canyon is the nearest surface water and lies at elevations of 7,400 feet to 8,200 feet. Major aquifers in the area consist of the Uinta — Animas aquifer, and according to published geologic maps, the bedrock exposed at the surface consists of the Uinta Formation. The Uinta — Animas aquifer in the Piceance Basin consists of the Uinta Formation and the Parachute Creek Member of the Green River Formation. Much of the intergranular space in the sandstone and siltstone is filled by sodium and bicarbonate cements; however, fractures are numerous and produce substantial permeability. Water Wells within the Site Boundary (Rule 908.b (7).B.iii) According to the COGCC website and the Colorado Division of Water Resources, there are no permitted water wells within Section 16, Township 6 South, Range 97 West. The nearest Geohydrology Report Page 4 permitted water wells are located in Section 17, Township 6 South, Range 97 West, at a distance of a mile away from the site. These wells are monitoring wells owned by OXY USA WTP LP, at lower elevation than the site, but are located cross gradient to the site and are located across the Conn Creek and Cascade Creek drainages. No springs are shown in Section 16 or Section 17; however springs are shown in Section 15 to the southeast across the Cascade Canyon. The springs are located at an elevation of less than 8,200 feet above mean sea level and are cross gradient from the site. Hydrologic Properties of Shallow Groundwater and Major Aquifers (Rule 908.b (7).B.iv) The Uinta — Animas aquifer in the Piceance Basin receives about 24,000 acre-feet per year of recharge, primarily in the upland areas near the margins of the aquifer. Discharge is approximately equal to recharge and primarily occurs in the valleys of Piceance Creek and other tributaries to the White River or in the valley of the Colorado River and its tributaries (Robson and Banta, 1995). The permeability of the major formations in the Piceance Basin aquifers is relatively low. Permeability of the Uinta — Anima aquifer is dependent on the location and orientation of fractures. The potentiometric surface of the Uinta — Animas aquifer generally ranges from about 100 feet above land surface to 500 feet below land surface; the surface generally is near or above land surface in valleys in areas of groundwater discharge. Larger depths to water are more common in highland areas that are remote from streams or other sources of recharge (Robson and Banta, 1995). In the Piceance Basin, the potentiometric surface ranges in altitude from about 6,000 feet to 8,500 feet, and groundwater primarily flows toward the discharge areas along Piceance and Yellow Creeks (Robson and Banta, 1995). The total dissolved solids in the aquifer range from 500 milligrams per liter (mg/L) to 3,000 mg/L. Site Location in Relation to Nearby Floodplains (Rule 908.b (7).B.v) The facility is not within a mapped FEMA flood hazard zone; however, it is located near the rim of the Cascade Creek canyon an area that may be prone to flash floods. The site is located within 1560 feet of Cascade Creek, but is at an elevation of 200 feet to 400 feet above the creek. The site is not subject to COGCC Rule 317B since it is not close to the segment of the Colorado River that supplies the town of De Beque with drinking water. The nearest mapped floodplains are approximately 12 miles to the south. Please refer to the Pond G Complex Floodplain Map. Existing Shallow Groundwater Quality (Rule 908.b (7).B.vi) Baseline groundwater quality sampling should occur prior to facility construction or modification to document pre -development conditions at the project site, as data in the area is currently not available. The groundwater quality, where it is present, is expected to be relatively fresh to `bicarbonate' type groundwater. Geohydrology Report Page 5 Potential for Impacts to Nearby Surface Water and Groundwater (Rule 908.b (7).B.vii) Cascade Creek could potentially be adversely impacted if a release from the facility were to reach it. Shallow groundwater resources are not expected at this location. The pond will be constructed with a HDPE plastic liner to prevent seepage.

The survey area is located approximately 10 miles north of DeBeque in Garfield County, Colorado. Location and Project Activities The survey area, which includes a uniform 0.5 -mile buffer around the existing project envelope, is located in southern Garfield County, Colorado (Figure 1). The legal location description of the approximate center of the project area is Section 16, Township 6 South, Range 97 West of the 6th PM; UTM NAD 83 Zone 12N, 783213m Easting, 4378834m Northing; Latitude, Longitude: 39.526480°N, -108.228776°W; USGS Circle Dot Gulch, CO Quadrangle. Oxy is the surface owner. An existing waste water pond occupies the site. The Pond G facility is fenced to exclude wildlife and for site security, and flagging deterrents have been installed to discourage birds from accessing the pond. Oxy proposes to made site modifications to improve long-term capacity and conditions at Pond G. There is no proposed change in disturbance footprint or type, timing, or number of vehicles accessing the site. The site is currently manned intermittently, as needed to support completion activities and would continue with this level of staffing based on activity level. The Pond G location is checked once per day for routine monitoring. The following modifications and activities are proposed within the existing previously disturbed footprint: 1. Drain, clean, and inspect the liner; make repairs as necessary; 2. Hydro -test for leaks; and 3. Drill 3 new groundwater monitoring wells. Activities 1 and 2 would require a total of about 3 weeks to complete. Activity 3 Durango would require about one week to complete. 1015'''/ Main Avenue Durango, CO 81301 970.422.2136 Setting Pond G occurs on a south-southeast aspect at an approximate elevation of 8,300 Western Slope feet above sea level (Figure 2).

Surrounding the disturbance area, the site primarily supports mixed mountain scrub -shrub habitat dominated by sagebrush (Artemesia tridentata sp.) and Gambel's oak (Quercus gambelii), with several narrow stringers of aspen (Populus tremuloides) occurring intermittently along the adjacent drainages. Dominant vegetation in the Pond G vicinity is shown in Table 1. Table 1. Vegetation observed near Pond G.

Sources: USFWS 2013 There is potential for one species with ESA "candidate status" — greater sage - grouse (Centrocercus minimus) — to occur near the project area. According to the Colorado Oil and Gas Conservation Commission (COGCC) maps developed by Colorado Parks and Wildlife (CPW), the project area is adjacent to a greater sage grouse production area (COGCC 2013, CPW 2013; ERO Figure 3). Most of the project area is disturbed, with graded slopes, pad/pond areas, facilities, and steep cut/fill slopes. Areas within the mapped project area (see Figure 2 and 3) are lacking in sage cover and bunch grasses required for sage -grouse production and forage. Some potential sage -grouse habitat occurs near the project area. Based on ERO's site review, sagebrush stands within and surrounding the Pond G project area are poor sage -grouse habitat for the following reasons, and are not anticipated to provide for sage -grouse life cycle needs: 1. Limited sage cover, with sage present belonging to a generally mature age class with relatively low recruitment; 2. Large interspaces and low cover of sage species; 3. Low percentage of bunch grasses in the understory; and 4. Hillsides are moderately to steeply sloped, and therefore do not provide optimal greater sage -grouse habitat. FRO Resources Corporatior. Page 4 Overall, the site contains relatively poor brood -rearing habitat for greater sage - grouse. The site was carefully reviewed, and no visible evidence — scat, secal dropping, tracks, or feathers — was observed during the site visit. General Wildlife A majority of the Pond G project envelope is disturbed or developed, and the facility is fenced to exclude wildlife. However, many wildlife species are known to occur in the area. Most are adapted to human -caused disturbances in the region. Species may include coyote, mice rats, raccoon, fox, various snakes, hawks, ground squirrels, and lizards. Oxy's wildlife policy states that Oxy employees and contractors will not harm or harass wildlife. A review of the NDIS map identified no sensitive ungulate habitat in the project area. Winter elk concentration areas occur about 0.5 mile south of the project area. No raptor nests or substrates were observed near the project vicinity at the time of the site visit. There also were no visual or auditory observations of raptors during the survey. Some aspen stingers are present though the trees are stunted and, based on past field observations, have low foliage cover during the growing season. The aspen stands likely do not provide suitable nesting raptor habitat and no raptors or nests were observed. Cliff habitat is present about 0.5 mile south of the project area. Migratory Birds Most birds in Colorado — with the exception of grouse and the non-native house sparrows, starlings, and rock pigeons — are protected by the MBTA. The regulatory definition of the MBTA prohibits, among other things, the act [or attempt] to pursue, hunt, shoot, wound, kill, trap, capture, or collect migratory birds, and applies to both live and dead birds as well as any part of their anatomy, nests, or eggs. However, the MBTA does not contain a prohibition that applies to the destruction of a migratory bird's habitat or the destruction of an inactive nest, as long as the nest or its contents are not collected. Nest destruction that results in the unpermitted take of migratory birds or their eggs is illegal and fully prosecutable under the rules of the MBTA (Migratory Bird Permit Memorandum, USFWS, April 15, 2003). The active nesting season for most migratory bird species in Colorado occurs between April 1 and August 31, which coincides with the peak construction season. Several state and federal agencies have adopted general species avoidance strategies, including vegetation removal outside of the breeding season, to preclude a violation of the MBTA. Impact Analysis The following sections evaluate the potential impacts from project implementation. The impacts can be completely mitigated; the approach to mitigate impacts is summarized in the "Recommendations" section that follows. Noxious Weeds No noxious weeds were observed during the site review; however, based on previous surveys, weeds likely are present. New activities, even if no new surface disturbance is proposed, can increase the distribution of noxious weeds via seeds trapped in equipment tires and crevices or personnel shoes and clothing. FRO Resources Corporatior. Page 5 Oxy monitors and treats noxious weeds seasonally, often beginning with bareground treatments in the early spring and spray applications as noxious weeds appear. Oxy tracks noxious weed treatment in compliance with Oxy's noxious weed management plan. TEPC Species No Threatened, Endangered, Proposed, Candidate, or other sensitive species occur in the project area. There are no anticipated impacts to this category of species. General Wildlife Temporary increases in human activity at the site may discourage use by some wildlife species; however, most species found in the project vicinity are acclimated to human presence and may temporarily alter their behavior patterns during active construction. The proposed project would not result in a permanent change in activity or any increase in the disturbance footprint; therefore no permanent impact to general wildlife habitat is anticipated. Oxy's wildlife policy states that Oxy employees and contractors will not harm or harass wildlife. Migratory Birds Clearing, grubbing, and increased human activity all have potential temporary and permanent impacts to migratory birds. No new surface disturbance is anticipated to result from proposed activities at Pond G; therefore no permanent impacts to migratory birds are anticipated. Increased human activity may temporarily discourage use of the project area by migratory birds; however this impact would be limited to the construction period. Following construction activities, birds are anticipated to resume their normal pattern of use and activity. Recommendations ERO recommends additional weed surveys and treatment be conducted prior to work at the site, in compliance with Oxy's Noxious Weed Management Plan. No new surface disturbing activities are proposed as part of the Pond G activities. If surface disturbance is required, ERO recommends the following step-down approach consistent with state and federal recommendations to avoid disturbing active bird nests during construction projects: 1. Conduct habitat -disturbing activities (tree removal, grading, scraping, grubbing, etc.) in the non -breeding season (September 1 to March 31) to the extent practicable. 2. If surface disturbing work activities are planned between April 1 and August 31, remove or alter vegetation within construction footprints and road right-of-ways (ROW) prior to April 1 to discourage nesting within areas scheduled for summer construction. Removal or alteration of vegetation will also discourage nesting in areas adjacent to the construction footprints and encourage birds to nest in more suitable habitat. Vegetation altering activities can include mowing or and/or trimming to a height of six (6) inches or less, grazing vegetation to a height of six (6) inches or less, disking, herbicide application, etc. FRO Resources Corporatior. Page 6 2a.Once vegetation has been removed and/or trimmed, appropriate measures, i.e. repeated mowing/trimming, should be implemented to assure vegetation does not grow more than six (6) inches. Note: Implementing these BMPs demonstrates a "Good Faith" effort to avoid incidental violation of the MBTA, but does not guarantee that migratory birds will not still nest in some areas despite these efforts. Additionally, depending on the elevation, weather, and species, the active nesting season may be earlier for species such as owls and raptors, or later at higher elevations. ERO recommends checking with a biologist to confirm the active nesting season in a particular location. No new surface disturbing activities are proposed as part of the Pond G activities. If surface disturbance is required, ERO recommends that all new temporary disturbance areas be reseeded with an appropriate seed mix, such as the mix shown in Table 3. Oxy will utilize the seeding mix identified in the SWMP. Table 3. Sample Montane Seed Mix.

The two fields operated by Oxy, the Cascade Creek Field and the Collbran Field, are both located within Garfield and Mesa Counties, Colorado, respectively. This operation includes +500 producing wells with associated production equipment and structures, several miles of natural gas and water gathering lines, satellite compressor stations and Targe compression facility. The office located in Grand Junction, Mesa County, Colorado serves as the support office for Piceance development. The business unit headquarters and additional support to Piceance operations is located in Houston, Texas. Most of the Oxy Piceance area operations in Garfield and/or Mesa County are located in rugged terrain, away from public access or direct influence. The enclosed maps show the general route of the field roads, well -site locations and major above -ground facilities. Natural gas is a safe, clean, dependable fuel used in millions of homes for cooking, heating, cooling and drying. It is also used by many commercial and industrial customers. Although typically safe to us, natural gas is an energy source and must be properly handled and does require a certain amount of caution when being produced and used. Natural gas is not poisonous; however, it does displace oxygen in enclosed spaces and may cause suffocation. In its pure state, natural gas is odorless. Odorants, in low concentrations, are added when the gas enters local distribution systems for safety purposes to serve as a warning of natural gas presence. DO NOT trust your sense of smell to identify a gas leak. The most effective method used by natural gas companies to locate leaks is with an instrument designed to "sniff" or locate leaks. A pipeline leak can be indicated by the following signs: (1) blowing sound; (2) dirt being blown into the air; (3) bubbles or water being blown into the air when the pipeline is located in a water source; (4) fire emanating from the ground or burning above the ground; (5) vegetation turning brown on or near the right-of-way; (6) persistent odor associated with natural gas. Natural gas is lighter than air and will not travel or accumulate close to the ground, as will liquefied petroleum gas (LPG) or gasoline fumes. It will rise quickly and be diluted in the atmosphere unless it is trapped within an enclosure. In order for natural gas to burn, it must be combined with air to a perfect mixture. When the gas is between 4 — 14% combined with air, it will readily ignite. Natural gas is compressible. It is compressed before entering transmission pipelines. Oxy Piceance area compressor and pipeline systems fully comply with state and federal standards for construction and operation. For production purposes, natural gas may also require the reduction and/or elimination of excess fluids and hydrocarbons. Separators and tri -ethylene glycol dehydration units are located at well locations and at the Conn Creek Compression Facility. The gas compression facility is not staffed 24 hours per day; however, emergency contacts are posted at the entry to the facility. Internal operations are monitored through electronic output with alerting capabilities 24 hours per day, 7 days per week. This facility is located on Oxy property. There are no residents within 1 mile of the facility. Public Safety Oxy Piceance area has operating procedures in place that are intended to protect the public and its employees from undue harm. In addition, the Company follows strict codes of compliance for the protection of public and Company property and the natural environment. When a concern for public safety is encountered within the Oxy Piceance area of operations, Oxy should be notified immediately! Oxy Piceance area employees and consultants are trained and equipped to handle unexpected conditions associated with the Company's natural gas production, gathering and processing systems. Emergency response organizations will be utilized where necessary and to assist with the public and neighboring properties during emergencies. Revised: 1 Aug 12 Oxy Piceance Area ERP Page 5 Emergency Response Plan (ERP) Components I. Pre -emergency Planning & Coordination With Outside Parties The following procedures cover emergency response guidelines that address anticipated emergency scenarios and define training required for employees engaged in oil or gas exploration and production (E&P) operations. The degree to which this ERP will be activated will depend entirely on the nature of the occurrence. There are (3) main options Oxy will decide when implementing the ERP, from most engaged to least engaged: offensive tactics, defensive tactics, and non-intervention. Remember, if offensive and defensive tactics are not feasible, there is always the option to non -intervene. The incident commander's option must account for life safety first, the environment second, and lastly, property (Oxy or non -Oxy). The Piceance ERP Manual will be reviewed and updated at least annually to reflect current activity and to increase effectiveness of the plan through discussions among all people involved. Each year Oxy employees are required to receive training on the ERP accompanied with real-life emergency drills, followed by a formal critique. These drills help improve the ER process, by addressing opportunities for improvement within the ERP system. This ERP has been shared with both Mesa and Garfield County officials, including the Local Emergency Response Commission (LEPC). The plan has also been distributed to the DeBeque Fire Department and the Plateau Valley Fire Department. II. Personnel Roles, Lines of Authority, Training, & Communication When feasible (dependent upon emergency severity) the Incident Command System (ICS) should be established consisting of a designated and trained incident commander, with assignments given to the four main categories for proper incident management: operations, logistics, planning, and finance. The incident commander will have the overall responsibility of determining what personnel best fits each needed function.

The purpose of this plan is to outline the responsibility for meeting such problems and to establish methods for handling the emergency with the least exposure to personnel, environment, and property. For the purpose of this plan, an emergency is considered to be any condition which requires assistance over and above that which can be supplied by the normal personnel present at the time or which cannot be handled in a routine manner. A first aid incident or minor fire which is limited to a small area, and which can be handled by the personnel present, does not fall under this plan. An emergency may include a medical emergency, fire, severe weather, explosion, uncontrolled release of natural gas or enemy action. Upon recognition of an emergency it is critical that the supervisor on location follow the appropriate incident notification outlined in Figure 1: Piceance Incident Notification Flowchart. Any lapse within the chain of Revised: 1 Aug 12 Oxy Piceance Area ERP Page 9 command locally, may severely damage the level of response needed, immediate crisis communication required to Oxy -Houston personnel, and Oxy's self-image and operating reputation within the community. Figure 2: Piceance Incident Notification Flowchart It is essential that all personnel are familiar with the location, operation and properly trained on fire extinguishers. Select personnel (i.e., plant operator) should be thoroughly familiar with all valves necessary to isolate the source of any natural gas leak, pipeline rupture, processing facility failure or other production related emergency. The location of all utility control points should be known by plant and field personnel, i.e., electric switch boxes, water and gas control valves. IV. Safe Distances & Places of Refuge Depending on the emergency, personnel shall evacuate to a location upwind and uphill, if possible. Personnel will meet at the designated safe area and a head count will be taken by the supervisor or the designee to ensure that everyone is accounted for. Each field area has specific pre -determined areas of refuge with a primary mustering point and a secondary mustering point (where applicable). It is important to note that each mustering point is identified with a mustering sign and a windsock (where applicable). Personnel should look for the mustering sign when evacuation is necessary. Below is a summary of the pre -determined mustering points for each field: (See the maps herein for aerial representation). Grand Junction Office: o Primary Mustering Point 4 Southeast corner of the parking lot o Secondary Mustering Point 4 Northeast corner of the parking lot Cascade Creek Field o Primary Mustering Point 4 Quadplex field office(s) o Secondary Mustering Point 4 Corral at Conn Creek Rd (GC Rd 213) & GC Rd 204 Collbran Field o East Plateau Area • Primary Mustering Point 4 East Plateau Field Office o Brush Creek Area • Primary Mustering Point 4 Brush Creek Field Office o Hell's Gulch Area • Primary Mustering Point 4 East of Compressor Station Site-specific evacuation routes, emergency procedures, and pre -selected muster points should be identified and confirmed at each pre -job and regularly scheduled safety meeting for daily work tasks. V. Site Security and Control The Operations Section, in conjunction with the incident commander shall be responsible for assigning company employees or contracted security forces to provide traffic control and establish a secure outside perimeter prior to being assisted by local emergency response personnel. Additionally, the hot, warm, and cold zones must be established for effective incident control. Figure 2 shows a generic incident layout. Revised: 1 Aug 12 Oxy Piceance Area ERP Page 10 Incident.

Revised: 1 Aug 12 Oxy Piceance Area ERP Page 31 VII. Decontamination Decontamination or DECON will be very limited to Oxy employees, due to the fact that offensive operations will be infrequent without the implementation of a respiratory protection program. However, it is the IC's responsibility to ensure that contract personnel involved with cleanup of hazardous materials follow proper DECON procedures. DECON shall always be established in the warm zone of an incident. VIII. Personal Protective Equipment (PPE) & Emergency Equipment PPE and emergency equipment is critical to an effective and safe emergency response for entry personnel. The Operations Section is responsible to ensure all entry team members are wearing the appropriate level of PPE. Currently, Oxy Piceance area have not implemented a respiratory protection program (RPP), since a program has not been deemed necessary for Oxy employees at this time. For this reason, PPE will strictly consist of an ANSI -approved hard hat and safety glasses w/ sideshields, ASTM -approved steel -toe boots or chemical resistant steel -toe boots, and 100% cotton/wool or FRC (flame resistant clothing). Additional PPE may include a Tyvek chemical splash suit, neoprene gloves, face -shield, goggles, etc., depending on the scenario. Of course, all emergencies shall require an appropriate PPE site analysis prior to entry. Emergency equipment is also critical to effective emergency response. Below is a general list of Oxy -provided equipment: (Note: this list may not be all inclusive) Emergency Equipment 1st Aid Kits 4 -Gas Monitor (CO, H2S, LEL, 02) Fire Extinguishers AED (automatic external defibrillator) (GJ office, CC Field office, CCCF Control room_) Backboard (located in CC Field Office) Explosion -Proof Flashlights Eyewash Stations & Bottles Spill Confinement Supplies (booms, diapers, pillows) (CCWHF, EPCS, Brush Creek office) Landing Zone LZ Turbo Lights (CC Field office, CCCF Control Room) St. Mary's Hospital Table 2: Emergency Equipment IX. Emergency Medical Treatment & First Aid In the event of an emergency involving injury to Oxy employees and/or contract personnel, immediate care shall be provided to the injured to abate any life-threatening injuries (e.g.; cardiac arrest, breathing stopped, and profuse bleeding, etc.), if deemed safe to do so. At least 50% of all Oxy employees are required to be trained in First Aid (FA), Cardiopulmonary Resuscitation (CPR), and the use of an Automatic External Defibrillator (AED). All other medical treatment beyond the first aid level, will require the evaluation of trained medical professionals from ambulance service to medical physicians at the clinic/hospital. The DeBeque Fire Department, the Plateau Valley Fire Department, and the St. Mary's Care Flight Helicopter can all provide advanced first aid at the Emergency Medical Technician (EMT) level. Hospital attention should be considered with respect to the below table, outlining medical facility protocol by priority. However, each emergency or incident should be managed case by case depending on injury severity. Priority Medical Facility Contact Number Non -Emergency Work Partners Occupational Clinic 970.241.5585 Non -Emergency Grand River Health & Safety Center 970.285.5731 Emergency St. Mary's Hospital 970.244.2990 Table 3: Medical Facility Protocol Revised: 1 Aug 12 Oxy Piceance Area ERP Page 32 X. Emergency Alerting and Response Procedure Once an employee recognizes the occurrence of an emergency, he/she will notify their immediate supervisor, following Figure 2: Incident Notification Flowchart. The on -scene Incident Command Staff shall notify the appropriate lines of authority and emergency response agencies as follows: A. Notify Mesa County Dispatch at 970.242.1234. B. Call law enforcement officers to help control traffic and the public, if necessary. If roadblocks are required and established during an emergency, advise the control points what outside help may be expected so that they can be admitted to the project area. C. Consider the necessity of evacuating any residents in the area. Currently, there are ranching interests and residential areas in the field(s) that may need notification. D. Establish contact with Civil Defense, Electric Companies, Gas Companies or other service organizations as needed. E. Contact Doctors, Hospitals, HAZMAT and ambulances as necessary. F. Contact any outside help necessary, such as construction contractors, tank trucks and other producers in the area which may be affected. G. Maintain communications and information flow with Oxy Piceance area and all potentially affected personnel. Notification to Oxy-MCBU management of any Health, Environment and Safety (HES) incident shall be made as soon as possible after the incident, so that additional steps can be taken as needed. Emergency response agencies as listed on page 3 of this plan shall be notified as needed. Below is the typical notification via the OXY chain of command, in accordance with OOG HES&S Procedure 60.400.0500 Incident Reporting and Investigation Standard.

Critique of Response & Follow-up Following all emergency response operations, a critique of the response efforts should be conducted to allow critical feedback that could improve the next potential emergency response management. This can be accomplished either verbally or in a structured, classroom setting outlining "what went right, what went wrong, and what can be improved on". The critique should always be documented for legality reasons. It is important to remember that a critique should be constructive, which means a positive effort is being conducted. An incident critique is not a "blame game". Additionally, all forms from each functional ICS group should be reviewed, for assistance with the critique. Any corrective actions developed from the critique should be documented and followed with action plans/target dates to ensure consistency with emergency response efforts throughout all operational phases. Revised: 1 Aug 12 Oxy Piceance Area ERP Page 34 Appendix A: Field Fire Prevention Plan Introduction The Fire Prevention Plan is a guide to help you know what to do and who to contact during a fire breakout in the mesa/valley where Oxy has operations. Having the available resources and knowing how to access them is crucial for someone who is involved in a fire incident and is injured or in critical condition. The information provided will help to increase an understanding of Oxy's policy and help in providing assistance to the general public and to Oxy should unexpected conditions arise which create a concern for public safety. All Oxy employees, contractors, sub -contractors, or anyone on Oxy -owned property should have the Emergency Response Plan (ERP) Manual available if needed for a resource in case of an emergency situation. The Fire Prevention Plan is in addition in the ERP Manual and specifically lays out a plan of action for workers to follow when an unexpected fire does happen. This section cannot cover all potential situations that may require emergency procedures. Check with the local Oxy representative for site specific procedures in effect for a particular work location. Types of Fires There are five general types of fires that have the possibility to occur on Oxy operations. They are lightning, smoking, flaring, hot work, and vehicle fires all which can result in a serious wild -land fire. Better understanding these types of hazards will only help you realize how to respond more efficiently if a wildfire occurs. Lightning Lightning is one of the most beautiful displays in nature. It is also one of the most deadly natural phenomena known to man. With bolts that are hotter than the sun, lightning can do some serious damage. One of the most common natural fires is caused by lightning. According to the Colorado Department of Local Affairs, "about half of all the wildfires in Colorado are lightning caused fires". Storms can move in very quickly on top of the mountain and lightning can become a severe hazard. In the United States alone, lightning sets 10,000 forest fires and causes $100 million in property damage every year. Always stay inside during a lightning storm; never go outside. If you are caught outside during a lightning storm avoid trees, fences, poles, or anything metal. Smoking The second type of fire is smoking. The best way to prevent a fire from smoking is to smoke only in designated smoking areas or in your vehicle. Never throw a cigarette butt outside. This is one of the most common ways fires are started. Pay attention to posted "NO SMOKING" signs and never smoke near flammable liquids or gases. Flaring Another potential fire hazard is flaring. Flaring or venting is a controlled burning process of natural gas that cannot be processed for sale or use because of technical reasons. Oxy has long used flaring and venting to Revised: 1 Aug 12 Oxy Piceance Area ERP Page 35 safely dispose of gases that occur in the production and processing of natural gas. In emergency situations, flaring provides a safe way to stabilize equipment. Hot Work A fourth fire danger is hot work which includes welding, grinding, and cutting. Each one of these is extremely dangerous because of the high fire danger they present. Dry, hot temperatures provide the perfect environment for sparks to ignite and start a wild -land fire. Every contractor who intends to perform one of these operations for Oxy must have a permit to do so before they start their job. Each contractor must have an established person that is the "fire watch" while the hot work is being performed. This person stands ready with an approved fire extinguisher to put out any fires that may start. The fire watch is required to remain at the hot work area for a period of 30 minutes after the job is complete. This lessens the chance of a fire occurring. Vehicle Hazards Another fire concern is vehicles that are equipped with catalytic converters. Catalysts reduce emissions by accelerating the combustion of pollutants leaving the engine. In doing this job, they get hot. The outside metal temperatures of some types of converters may approach 800 to 1000 F under conditions of extremely high engine loading. In other words, catalytic converters on vehicles get extremely hot after a long drive up the mountain. So parking should be only in a designated parking area at the location. Never park a catalyst - equipped vehicle, or any vehicle, on a pile of dry grass/brush or other dry vegetation. Always park where you can easily access the nearest exit by driving forward. Survey the scene so you know your exits for means of a quick escape. When a Fire Breaks Out: If a potential wildfire breaks out on the mesa, the most important thing is accountability. First of all notify someone of the fire, whether it be your supervisor, coworker, etc. Second, call the Mesa County Dispatch immediately at (970) 242-1234; the sooner the fire department is dispatched, the quicker the response time will be. All fires on federal lands should require immediate notification to the applicable Oxy personnel. Then analyze the situation and determine what the potential hazards are. Ask yourself these questions: Are there any hazardous or toxic chemicals at risk? Is the fire life threatening? Is there damage to public property? If possible and not a risk to life, isolate the fuel sources. Next, determine if the fire can be extinguished, if so, alert someone else of your plans, locate the nearest fire extinguisher and proceed to put the fire out. Every employee of Oxy should be trained on how to properly extinguish a fire. Note: Oxy recommends fighting a fire ONLY in the incipient stage. What is the incipient stage? A fire in its beginning stage. Incipient stage fires can be controlled with portable fire extinguishers. There are (4) steps to extinguish a fire called the PASS system: Pull - Pull the safety pin Aim - Remove the hose and aim the nozzle toward the fire Squeeze - Holding the handle, squeeze the trigger Sweep — Extinguish the fire in a sweeping motion, from left to right Revised: 1 Aug 12 Oxy Piceance Area ERP Page 36 When to Leave If the fire cannot be put out by the fire extinguisher in the incipient stage, it is time to evacuate the area immediately. Communication is key, inform everyone to evacuate the location and make sure everyone is accounted for. There should be designated meeting or muster points on location, where the entire crew/employees would meet in the event of an emergency. During the brief meeting, decide which route is the safest to use and evacuate as soon as possible. Cascade Creek There are (4) alternative routes of escape from Oxy Cascade Creek operations. The first three possible exits are drivable escape routes and the latter is a cow trail. The primary escape route is off the Oxy road leading to Conn Creek Road. The second is off Logan Wash Road if possible. The third alternative is to drive north on Trail Ridge Road, which is the road that lays directly north of the mesa well locations. If you stay on Trail Ridge Road it will eventually take you north to Rio Blanco County on County Road 5 and then to Colorado Highway 13. The other possible route would be to hike down the cow path that is connected to Oxy's valley operations. This allows (4) different evacuation routes where if one exit is blocked there is always an alternative. Please note the (3) secondary routes are ONLY for emergency access and are intended for the safe escape of Oxy contractors/sub-contractors. Collbran There are (3) alternative routes from the Oxy Collbran operations. All three are drivable escape routes on public highways. From the East Plateau area, one can take 60 Road, 59 '/2 Road, and Grove Creek Road North to Highway 330 and then head eastbound to Highway 65 to 1-70. A secondary escape route can be followed by heading South on 59 Road, to AA 50 Drive, to Lakeshore Drive, to Highway 65 southbound to Delta, then to the City of Cedaredge, to the City of Delta at Highway 92. The Brush Creek area primary escape route is Highway 330 eastbound to the City of Collbran and then eastbound to Highway 65, to 1-70. A secondary route can be followed westbound on Highway 330 to Northeast County Road 342, to North Divide Creek Road to the City of Silt and then 1-70. The Hell's Gulch area primary escape route is south on Canyon Road 342, to Highway 330 eastbound to the City of Collbran, and then eastbound to Highway 65, to 1-70. A secondary route can be followed westbound on Highway 330 to Northeast County Road 342, to North Divide Creek Road to the City of Silt and then 1-70. Where To Go Once you have evacuated the area, the primary muster point for each individual on the Cascade Creek lease would be the Oxy field offices. (Secondary is the cattle pens at Conn Creek Rd GC 213 & GC Rd 204.) Everyone should meet there and be accounted for by the supervisor in charge. If your path of escape is Trail Ridge Road, continue until you reach Piceance Creek, Rio Blanco county roads. Travel east on Rio Blanco County Road 5 to Colorado Highway 13 and then south on Highway 13 to Rifle, CO and Interstate 70. Revised: 1 Aug 12 Oxy Piceance Area ERP Page 37 Once you are in the safe zone contact your supervisor immediately for accountability. Drive careful and when emergency vehicles are met on the road, pull over and always give them the right away. Report all fires, regardless of the size to an Oxy representative as soon as possible. If a situation occurs where all exits are blocked, find a location with a bare, dirt pad and wait out the fire. Park your vehicle the farthest point away from all production units and methanol/condensate tanks and turn the engine off. Stay in your vehicle with the windows rolled up and the air conditioner/heater off, with all vents closed. This will keep smoke from entering the vehicle. Who/What is in Danger? There are several major operations that are in the danger zone if a fire breaks out. Drilling rigs, multiple production sites, various contractors on location, hunter/rancher cabins, and particularly temporary housing units are a major concern for Oxy. Also, other oil/gas companies in the area travel daily on Logan Wash Road and could also be affected. Temporary Housing Units One of the most susceptible places for a wild -land fire to catch employees off -guard is the temporary housing units. Remote locations provide an opportunity for a fire to easily arrive and trap employees with no access/egress to escape. The temporary housing units are being assessed per Colorado state and county regulations to ensure the health and safety of each employee. Fire Dangers/Hazards The following is a list of things that should be considered for fire prevention: • Temporary housing units must be a minimum of 75 feet from the well -head and condensate/methanol tanks. • Smoking is allowed only in designated smoking areas. Smoking is NOT ALLOWED inside any temporary housing units owned or leased by Oxy on Oxy property. Matches and all smoking equipment may not be carried into "No Smoking" areas. Butt disposal containers should be placed in the designated smoking areas. • Absolutely no drugs, alcohol, or firearms. Methamphetamine laboratories are EXTREMELY DANGEROUS and will not be tolerated on Oxy property. • All exits must be maintained free and clear of any obstructions. Exits must have free clearance of 10 feet. EXIT signs must be posted at each exit in the facility. Center to center between trailers must be maintained at a minimum of 20 feet.

How To Prepare for a Fire? Evacuation Drills/Training Every drilling rig crew, temporary housing occupants, and contractor that is staying on the mesa for a set time frame is required to have routine evacuation drills and training. Supervisors should provide information concerning the (4) evacuation routes, existing fire hazards, and important safety concerns on a weekly basis. Employees need to know the Fire Prevention Plan, so when the unexpected does happen, they will be ready. The Emergency Response Plan (ERP) Manual and Fire Prevention Plan is available upon request to each critical contractor/employee before employment, with the expectation that the critical contractors/employees will brief individuals and visitors they oversee. The fire hazards will be discussed and any questions or concerns should be brought to attention immediately. It is important to know the potential hazards that exist during a job and the resources that your safety depends on. Fire Prevention Checklist To ensure that you know this fire plan, ask yourself these questions: ✓ What fire hazards exist around me? ✓ What are the (4) evacuation routes that are available? ✓ What is the best exit for a means of escape? ✓ Who do I call in case of a fire? ✓ Where do I access emergency contact information? ✓ Is the fire life threatening? ✓ Where is the closest fire extinguisher? ✓ Where is the muster points in case of an emergency? ✓ What is the weather like, windy, thunderstorms, etc.?

Box 1628 • (;rand Junction, CO S1502-1628 11 St. Mary's CareFljght HOW TO PREPARE A LANDING ZONE 1-800-332-4923 Selecting an On -Scene LZ (Landing Zone) First, determine if the area is large enough to land the CareFlight helicopter safely.The landing surface should he flat, firm, and free of debris that would blow up into the rotor sys- tem or be a hazard to persons at the scene. Touchdown Area: The touchdown area should be square with a minimum of MO feet on each side. The landing site should be clear of people, vehicles, and obstructions such as trees, poles, and wires. Keep in. mind that wires cannot be seen from the air at night. The landing site must be free of stumps, brush, posts, and Targe rocks. Wind Direction & Touchdown Area Consider the wind direction. Helicopters land and take off into the wind. Inform the pilot of the direction from which the wincl is blowing. i.e. "Wind from the era>rtb.' Is the approach and departure path free of obstructions (wires, poles, antennas, trees, etc.)? If there arc obstructions, please tell the CareFlight team during the initial radio call. Illumination of the LZ at Night Mark the touchdown area with five lights/road flares (one in each corner and one indicating wind direction). When using automobile(~), place the vehicle(s) in position based upon the number of vehicles available. For instance, if only one vehicle is available, place it in vehicle #1 position (pointing into the wind). If two vehicles are available, place them In vehicle #1 and ?r2 positions, etc. Ilse any additional vehicles (if more than 3 available) to illuminate flight and land- ing surface obstacles. At night, assure that spotlights, floodlights, vehicle lights, and handlights used to define the I2. and obstacles are not pointed toward tlic helicopter.lurn off non-essential Iights.White lights, such as spotlights, flash bulbs, and headlights ruin the pilot's night vision and temporarily blind him. Red lights or blue lights, however, are very helpful in finding accident locations and do not have a detrimental effect on the pilot's night vision. Select a landing site clear of trees, pales and wires. Keep approach/departure path free of obstructions. When using automobiles to illuminate the nighttime landing zone, place in the positions as shown above. 11 Revised: 1 Aug 12 Oxy Piceance Area ERP Page 40 LISt. Mary's j CareFlight Personnel Safety Keep spectators at least 20() feet from the touchdown area. Keep emergency service personnel at least 100 feet away, if possible. Encourage everyone working near the helicopter to wear eye protection. Remove hats or helmets or fasten chin straps (no loose hats blowing up through rhe rotors)? Reties of Thumb for Safe Distances: • 100 feet from helicopter to waiting ambulance • 200 feet from helicopter to crowds & pedestrians • 300 feet from the helicopter to stopped traffic • 200-400 feet from accident victims to traffic Ground Guide: When CareFlight arrives at the scene, only one person should give 12, wind, and obstacle instructions. 'Ibat person should wear eye protection and they should stand with their hack to the wind and arms raised over head to indicate the direction of the wind, which will usually be the opposite of the landing direction. As the helicopter turns into the wind, and begins the final descent, the ground guide should leave to a safer area, Communications One person, the 1,Z coordinator, will be responsible for all communication with the pilot.The 12 coordinator should monitor the radio at all tithes when the helicopter is running. It is CareFlight's policy 0) monitor the 12 frequency for at least two minutes after departure_ Every attempt will he made to contact the 12 coordinator on the frequency specified in the dispatch call. In the event that communication cannot be established on that frequency, the helicopter will monitor NLEC (National Law Enforcement Channel). Please immediately report to the pilot any observed hazards and wait for his acknowledgement. TOUCH DOWN AREA WIND D!

General He[itopter Safety Rules • The pilot will perform as many high reconnaissance whit as they feel necessary to insure a safe landing. • When working around any helicopter, never approach from the rear.A1ways approach and depart the aircraft towards the front so you can see the pilot and so he ran see you, The I.7, coordinator will designate as many persons as neces- sary for crowd control. • If the helicopter is landed on a slope approach and depart .from the down-slope side, unless that is the rear of the heli- copter -An that circumstance, approach from the left or right from the most level ground and in plain Sight of the pilot. • "When the helicopter is loaded and ready for take -off, keep the departure path free of vehicles and spectators or rescue personnel. If an emergency were to occur during take -off, we would need this area to execute our landing. Assistinl� the CareFlight team Once CareFlight has landed, only briefed emergency person- nel should approach the helicopter. Be sure to receive a"go- ahead" sign from the pilot before stepping under the rotor tip path and then approach from the front of the helicopter h landing zone coordinator should be prepared to assist the crew by providing security for the helicopter The tail rotor is the most dangerous area -if asked to provide security, do not allow anyone but the crew to approach the helicopter.

Revised: 1 Aug 12 Oxy Piceance Area ERP Page 42 Hazardous Chemicals/Gases Accidents involving hazardous materials require special han- dling by Fire/Rescue units on the ground. The preparations far helicopters responding 0) these accidents also require spe- cial considerations. Helicopter medical craws normally do not carry protective snits or breathing apparatuses to protect them from hazardous materials. Upon initial radio contact, the CareFlight team must he made aware of any hazardous materials or gases in the area. If the aircraft were to fly through the hazardous gases, the crew could he poisoned and the engines could develop mechanical problems, or cause an explosion or fire, Never assume that the crew has already been informed of the 1-I oijnat situation. Hazardous materials of concerts are toxic, poisonous, flamma- ble, explosive, irritating, or radioactive in nature. Patients exposed to hazardous materials will require decontamination prior to air transport to avoid contamination of the crew and aircraft. Some radioactive materials are more dangerous than others, depending upon the type and amounts of those materials. In general, radioactive materials are difficult to ignite, but will born, and the smoke is toxic. The CareFlight team should he advised if victims niay be con- taminated by radioactivity. Hazardous Materials LZ Preparation and Considerations Ile[lcopter landing zones muse he selected to avoid possibility of compromising the safety of the CareFlight team and adja- cent people and property, When explosives, poisonous gases/vapors, or chemicals in danger of exploding and burning are on site, helicopter landing t zones must be prepared upwind, a safe distance (may he as much as one mile) from the hazardous material accident site, and never in low-lying areas.Tlte toxic gases or vapors may be heavier than air ala[ gather in these low-lying areas. For hazardous material accidents involving radioactive materi- als, the CareFlight 12 must be prepared upwind, a safe distance (mar be 1/4 mile) from accident, unless there are radioactive gases (steam or smoke), and in this case, the LI, must he at lease one mile upwind of the accident site. CareFlight must be notrfied of .hazardous materials on the scene in order to ovoid contamination of the flight tech -17 and aircraft.

Per the Garfield County Land Use and Development Code, effective July 15, 2013, Oxy is requesting a Limited Impact Review permit for "Materials Handling and Water Impoundment". The project area is situated in the Resource Land -Plateau zone district. The water to be handled at this facility is produced from drilling, completion and production operations associated with natural gas wells within Oxy's Cascade Creek Operations. Water that is produced from these operations is classified as an exploration and production (E&P) waste by the COGCC. Pursuant to COGCC Rule 908, this facility will also be permitted as a Centralized E&P Waste Management Facility with the COGCC. The existing produced water impoundments are currently permitted as a Form 15 use by the COGCC. Oxy is pursuing permitting for the existing water impoundments as E&P Waste Management facilities and is in the process of submitting a Form 28 to the COGCC for their review. All water stored at this location will be from a non -tributary water source within the Williams Fork and Niobrara formations. Pond G is in the SE 1/4 of the NW 1/4 of Section 16, Township 6 South, Range 97 West, of the 6th Principal Meridian, in unincorporated Garfield County, Colorado. Oxy is the surface owner. The proposed Centralized E&P Waste Management facility will allow for effective re -use of water volumes to conserve resources, improve safety and environmental exposure, and reduce costs. The goal of this water impoundment project is to conserve water by recycling flow -back and produced water for re -use in well stimulations or drilling. The ability to temporarily store water at this location has several key benefits: • Reduced trucking / improved safety • Use of engineering controlled transfer system • Reduction in volumes of disposed water • Conservation of freshwater • Reduced road maintenance • Overall reduction in development and operating cost 760 Horizon Dr., Suite 102 TEL 970.263.7800 Grand Junction, CO 81506 FAX 970.263.7456 www.olssonassociates.com Details of this request along with the information required by Garfield County's (GarCo) Limited Impact Review (LIR) application are provided within the context of this submittal.

The project has been designed in accordance with the Colorado Oil and Gas Conservation Commission (COGCC) standards. The planned use of the site is a water impoundment and storage area. A Reclamation Plan has been prepared by Olsson Associates to accommodate this project. Grading and Drainage Plan 1. Site Map: The proposed site will not differ from the existing site. The existing site features are identified within the Reclamation Plan. 2. Drainage Structures: Additional design is not anticipated since the proposed site and the existing site are the same. Additional disturbance is not anticipated. 3. Topography: The attached exhibit within the Reclamation Plan illustrates the existing topography of the site. Additional grading is not anticipated. 4. Grading Plan: The existing topography is anticipated to remain. 5. Soil Stockpile and Snow Storage Areas: Soil stockpiles and snow storage is not anticipated to differ from the existing use. 6. Drainage Plan: The existing drainage patterns are not anticipated to be modified. 7. Equipment Storage Areas: A proposed use of the facility is for storage. No hazardous material is expected to be stored at the site. Best management practices outlined within the stormwater management plan referenced in the Reclamation Plan will be followed. 8. Temporary Roads: Temporary roads are not anticipated with the development. The existing infrastructure is expected to serve the site. 9. Areas of Steep Slope: The existing side slopes surrounding the site are steeper than 20% and are expected to remain undisturbed. 10. Construction Schedule: A construction schedule is not anticipated since the site currently exists. 11. Permanent Stabilization: The site is currently stabilized through the use of existing vegetation. 760 Horizon Drive TEL 970.263.7800 Grand Junction, CO 81506 FAX 970.263.7456 www.oaconsulting.com 12. Erosion Control Measures: Erosion control measures are not anticipated since the site is currently stabilized. 13. Estimated Cost: Construction was under an APD. This is an existing site and no new construction is anticipated. 14. Calculations: Drainage design is not included since there are no anticipated changes to drainage patterns. 15. Neighboring Areas: The site is surrounded by oil and gas activity. 16. Stormwater Management: Stormwater management will be in accordance with the previously prepared stormwater management plan referenced within the Reclamation Plan. 17. Stormwater Management Plan: A copy of the permit is included within the Reclamation Plan. 18. Reclamation Plan: A Reclamation Plan is included with the submittal. 19. Hydraulic Calculations: Drainage design is not included since there are no anticipated changes to drainage patterns. 20. Maintenance Requirements: Maintenance requirements are discussed within the stormwater management plan referenced within the Reclamation Plan. 21. Spill Prevention Control and Countermeasures Plan: Not applicable. 22. Additional Information: None. 23. Signature Block: See below. Additional construction is not anticipated, therefore, the previously stabilized areas are not anticipated to be disturbed.

Upon closure of the site, revegetation activities are anticipated to take no longer than forty (40) days weather permitting. Upon closure of the site, the disturbed area will be re-contoured at slopes no greater than 2:1 to catch the existing terrain. Topsoil will be replaced on the disturbed areas. The entire disturbed area will be reseeded with the following seed mixture: Mixed Mountain Shrubland, Including Oakbrush Common Name Scientific Names Form PLS 1 bs/acre* Thickspike Wheatgrass Elymus lanceolatus ssp. lanceolatus, Agropyron dasystachyum Sod- forming 3.4 Bluebunch Wheatgrass Pseudoroegneria spicata, Agropyron spicatum Bunch 3.7 Bottlebrush Squirreltail Elymus elymoides, Sitanion hystrix Bunch 2.7 Slender Wheatgrass Elymus trachycaulus, Agropyron trachycaulum Bunch 3.3 Canby Bluegrass Poa canbyi, P. secunda Bunch 0.6 Mutton Bluegrass Poa fendleriana Bunch 0.6 Letterman Needlegrass Achnatherum [Stipa] lettermanii Bunch 1.7 Columbia Needlegrass Achnatherum [Stipa] nelsonii, Stipa Columbiana Bunch 1.7 Indian Ricegrass Achnatherum [Oryzopsis] hymenoides Bunch 1.9 Junegrass Koeleria macrantha, K. cristata Bunch 0.1 *Based on 60 pure live seeds (PLS) per square foot, drill -seeded. Double this rate (120 PLS per square foot) if broadcast or hydroseeded. Top Soil Management Topsoil has been reutilized during the initial construction of the site for initial reclamation. During closure of the site the topsoil will be re -stockpiled so that it will not interfere with closure activities. Should the reclamation activities during the closure phase exceed forty (40) days, appropriate measures will be taken to protect all topsoil stockpiles (covering, seeding, windbreaks, etc.). Following final contouring, all disturbed areas will be covered evenly with the stockpiled topsoil. The topsoil will be heavily pocked using the excavator bucket to form an uneven soil surface 1 complex which will aid in revegetation. Soil amendments or import of new topsoil is not anticipated. Review of the vegetation establishment will be required to determine whether soil amendments are required at a later date. (Attachment A). Seeding Procedures and Schedules As recommended grass mixture reseeding will be done in late autumn in order to take advantage of natural precipitation for the region. The reseeding rate should be doubled for broadcast application. Oxy's contractor will utilize a no -till -drill without any soil preparation other than simple grading to slope and waterbars, where applicable. It is anticipated that the disturbed areas will be returned to match the original vegetative state. Seeding will be conducted by means of drilling the prescribed seed mix according to the recommended rate. The seed will be drilled with a common range drill at a depth of 0.25 — 0.5 inch beneath the soil surface. The reseeding will be monitored and reseeded as appropriate until the reclamation standards are acceptable to Garfield County Vegetation Management. The reclaimed site will be monitored for stormwater and noxious weeds. Disturbance area The project has an anticipated total disturbance of approximately 4.1 acre. (178,596 square feet). Engineer's Opinion of Probable Cost Below is a table that outlines the estimated costs associated with the revegetation of the project during final closure. There are no costs associated with the initial reclamation. The estimate is an opinion of probable cost and may vary based upon site conditions encountered or market conditions related to the unit cost. (JoLssoN ASSOCIATES Olsson Associates 760 Horizon Drive, Suite 102 Grand Junction, CO 81506 REVEGETATION COST SUMMARY PROJECT: Pond G LOCATION: Garfield County, CO DATE: 8/1/13 Item Description (Source of Cost) Garfield County Vegetation Management Cost/ Acre $2,500 Total Acres 4.1 Estimated Total Cost $10,250 (costs have been provided by Garfield County Vegetation Management) 2 Drainage and Erosion Control Plan The primary disturbance anticipated with the closure Pond G is re -grading. Topsoil will be stockpiled so that it will not interfere with closure activities. Should the construction activities during the closure phase exceed forty (40) days, appropriate measures will be taken to protect all topsoil stockpiles (covering, seeding, windbreaks, etc.). The final reclamation plans prepared by D.R. Griffin and Associates, Inc illustrate the proposed final grades. Drainage Nolte Associates prepared the Regional Drainage Analysis. The improvements associated with this project are located within the CA02 drainage basin as described within the Regional Drainage Analysis. This project is not anticipated to significantly alter the drainage patterns or flow rates described within the Regional Drainage Analysis. Additional analysis may be warranted due to the nature of construction activity associated with this project. However, it is expected that existing drainage measures will be maintained. Deviation from the Regional Drainage Analysis is not expected, however, if site conditions dictate a deviation then a Colorado Registered Professional Engineer shall be consulted. The Regional Drainage Analysis prepared by Nolte Associates demonstrating drainage patterns for the project area is included as Attachment B. Erosion Control Measures Olsson Associates prepared a Stormwater Management Plan (SWMP) for Cascade Creek Development. It is anticipated that the project will be in conformance with Oxy's SWMP (permit no. COR038414). The Stormwater Management Plan will be revised accordingly. An exhibit demonstrating approximate locations of anticipated erosion control measures is included as Attachment C. Closure will be completed as described in the Reclamation Plan and SWMP. The recommendations associated with the Reclamation Plan and review of the Drainage and Erosion Control Plan were prepared on behalf of Olsson Associates under the supervision of: Wyatt E.

Background The Colorado Noxious Weed Act (C.R.S. Title 35, Article 5.5) requires that "noxious weeds" be managed on private and public lands. The Act further declares that control of noxious weeds should use methods that are least damaging to the environment but also practicable and economically reasonable. The state requires management of noxious weeds included on one of three lists (see Appendix A): List A — designated for statewide eradication; List B — managed to prevent further spread and, for selected species, designated for eradication in large areas; and List C — of more localized concern, but for which the State will provide education, research, and biological control assistance to jurisdictions that choose to manage the species. OXY USA WTP LP and OXY USA Inc. (individually and collectively referred to herein as "Oxy"), are affiliated companies that separately own and operate certain mineral properties in the State of Colorado. This plan is intended for all Oxy operations in order to comply with all state and federal requirements including the Colorado Noxious Weed Act, Colorado Oil and Gas Conservation Act, Bureau of Land Management (BLM) and Forest Service (FS) National Invasive Weed Strategies, Mesa County and Garfield County weed standards. 2. Compliance Statements Oxy will manage all noxious weeds, as defined by the Mesa County, Garfield County or State Law (CRS 35-5.5), in all newly disturbed project areas using recommendations identified in this plan or those provided by biological consultant at the time of project specific inventories. The term, "disturbed area" includes all access roads, easements, pipelines, special purpose pits, berms, soil stockpiles, well pads, electrical and compressor stations and other structures, and other areas disturbed by project activities. Oxy will immediately report all State List A and List B populations to be eradicated and any other species slated by Mesa and Garfield Counties for eradication upon discovery to the appropriate County designee. 3.

Locations Oxy has active and inactive leases for gas exploration in the following areas of Mesa and Garfield Counties: • Cascade Creek (Garfield County, Colorado) • Collbran Area (Mesa County, Colorado) Oxy operates on split estate, wholly federal (both BLM and USFS), and wholly private land and lease holdings. 5. Land Use Objectives Oxy conducts natural gas exploration on lease holdings in Colorado. Land uses and types of facilities to be developed include access roads, pipelines, well pads, compressor stations, staging/storage areas for equipment and supplies, and other associated natural gas development activities. Some of the developments are short- term temporary disturbances, such as staging areas and pipelines, while the roads and well pads will be in place for an estimated 20-30 years. 6. Weed Management Objectives and Implementation Strategies The following are the overall objectives of Oxy's weed management plan. Specific actions to be taken to meet these objectives are detailed in Section 6. 1) Inventory and monitor existing noxious weed infestations using GPS or other mapping techniques and consistent field documentation; 2) Prevent new infestations of noxious weeds; 3) Implement Integrated Weed Management (IWM) to control or manage noxious weed populations; 4) Maintain weed inventory, herbicide application and mapping records; 5) Restore disturbed areas to their proper ecological function to protect native plant ecosystems and watersheds from degradation by noxious weeds. 6.1 Inventory and Monitoring Before a new site is developed, Oxy will inventory the site and adjacent areas for noxious weeds, including access roads and other probable weed ingress routes. Noxious weed locations (List A and List B species) will be collected with a GPS unit. Any noxious weed infestations found will be treated before site disturbance, if timing is appropriate. If the season is not appropriate for weed treatment, activities may proceed and the weeds will be monitored and treated during the appropriate season. Weeds on adjacent properties may be treated as appropriate with permission of the landowner. Populations of Colorado or County List A and List B species (see Appendix A) will be reported immediately to the County Weed Manager. On Federal property or for federal projects, a Noxious Weed Inventory record will be completed each time a List A or B weed infestation is inventoried (with the exception of redstem filaree and quackgrass), and the populations will be reported. Monitoring will be conducted at least once a year, early in the growing season, by Oxy staff or contractors, and in coordination with BLM or FS staff on federal lands. For most of Oxy's operation areas, monitoring will occur between May and July. All previously treated noxious weed sites will be monitored for regrowth and scheduled for re -treatment as necessary. All disturbed areas under Oxy management will also be monitored to ensure there are no new weed infestations. 6.2 Prevention The purpose of prevention measures is to preclude the introduction of new or existing noxious weeds from the project area to un -infested areas or from adjacent land into the project area. 6.2.1 Construction Prevention Measures Construction equipment entering project areas (backhoes, trackhoes, dozers, blades, rollers, lowboys, equipment trailers, etc.) will be power washed or otherwise cleaned. "Equipment" is defined as any earth moving and any other machinery, trucks or vehicles, trailers and tools. On Federal property, equipment may be inspected by USFS or BLM personnel. Pickup trucks, SUVs, vans, water trucks, and pipe trucks should also be clean but do not require inspection prior to entering federal lands. Track pads, gravel beds or rumble strips will be installed at ingress/egress points to the site to limit weed propagules from entering or leaving the site. Soils from infested areas of the project site will not be moved off site, but will be stockpiled and treated for weeds as necessary. If infested soils are moved off site, they will be kept on Oxy -managed property, monitored, and treated as necessary. Stockpiled soils will be monitored and treated to control noxious weeds. All purchased products used in development and reclamation of a site will be inspected or certified as weed -free whenever possible, including soils, rock and gravel, seeds, mulch and erosion control products. 6.2.2 Revegetation The goal of reclamation and revegetation of a site after disturbance is timely establishment of a desirable plant community and prevention of noxious weed infestation. "Timely" is defined as "by the end of the second year of project completion" (BLM 2007). Elements of successful revegetation include the use of topsoil that was set aside during construction and kept weed -free; reseeding with appropriate species to establish plant cover, and stabilization of the soil surface with the appropriate mulches, tackifiers, and erosion control products as needed. Plans for revegetation and reclamation of disturbed areas are site-specific, and will include a plant list, method of seeding, how seeding success will be determined and how the revegetated area will be monitored. Most private landowners request re -seeding with common pasture grasses, including timothy, (Phleum pratense), brome grasses (Bromus or Bromopsis), orchardgrass (Dactylic glomerate), and oats, tricale, rye, or wheat as an annual covercrop. USFS and BLM seed mixes are compiled on a site-specific basis, according to elevation and existing vegetation community on the site. Non-native, non-persistent sterile grasses may be used to provide ground cover for soil stabilization and weed suppression during temporary reclamation on both private and federal land. See Appendix C for a sample Oxy Revegetation and Reclamation Plan. Certified weed seed free straw, hay, mulch, seed or other materials will be used for soil stabilization and/or revegetation purposes (Colorado Department of Agriculture certified inspector to State standards). Seed tags will be available for inspection upon request of the Inspector. Topsoil that is stock piled for more than one year will be seeded according to above standards at the earliest practical time to reduce the possibility of noxious weed establishment. Revegetation efforts will be monitored annually until successful establishment of desirable or intentionally planted seed or plants is confirmed. Noxious weeds found in revegetation will be documented, and managed per guidelines in this Weed Management Plan. 6.3 Control and Management A comprehensive multi -strategy approach utilizing IWM will be employed to detect, map, treat and control noxious weeds. Treatments will include herbicide, cultural, mechanical, revegetation, and biological control alone or in combination as necessary for efficient weed control. On Federal lands, control and management methods (including herbicide use) will be verified and approved with the appropriate land management agency representatives. Activities on BLM lands in Colorado requires submittal of a "Pesticide Use Proposal Form" (BLM 2007).

Appendix B Excel Spreadsheet Components and Example Tables for Pesticide Reporting The Excel spreadsheet table will contain the data fields listed below. This information should have been recorded on Noxious Weed Inventory and Pesticide Application records completed during the field season. The Excel spreadsheet will contain a new entry for each weed inventory and/or pesticide application. Infestation Number (IN #): Needed when List A or List B species (with the exception of redstem filaree and quackgrass) are inventoried and treated. This is the unique number or code associated with each weed infestation. Date: Date of the weed inventory and/or treatment Observer/Applicator (Obs/Appl): Person conducting the inventory and/or applying the herbicide. Weed Name or Bare Ground: Common name of the weed. If it was a bare ground treatment state as such. UTM Easting (UTM E), Northing (UTM N) and Zone (Z) (should always be in NAD 83) or use Lat and Long if preferred. Be consistent with which one is used. Infested Acres (Inf Acres): List how many acres are covered with the weed. Density (Dens) i.e. Cover: L= Low (less than 5% total canopy cover) M = Moderate (5% - 25% canopy cover) H = High (more than 25% canopy cover) Surface ownership (Own): BLM, FS or private Herbicide Trade Name (Tr Name) or Treatment Method — if a manual or biological treatment state as such. Chemical Names (Chem Name) — Only needed when using an herbicide with multiple active ingredients or when using a mixture of chemicals. For example, if using Sahara DG which has two active ingredients, imazapyr and diuron, enter the first two letters of each active ingredient. e.g. im + di. See Excel spreadsheet example. Application Rate (Pounds Active Ingredient (A.I.)/Acre or Pounds Acid Equivalent (A.E.)/Acre): For those herbicides with multiple active ingredients, multiple columns for the application rates are provided. Application rates should be entered in the same order chemical names are entered. For example, for Sahara DG, the A.I./acre of imazapyr would be entered in the first Application Rate (AR #1) column. The A.I./acre of diuron would be entered in the second Application Rate (AR #2) column. If an additional chemical was used in the mix it would be entered in the third Application Rate (AR #3) column. Total Pounds Active Ingredient (A.I.) or Acid Equivalent (A.E.) Applied: For those herbicides with multiple chemicals, multiple columns for the pounds of A.I./A.E. are provided. Pounds of A.I./A.E. should be entered in the same order chemical names are entered. For example, for Sahara DG, the pounds of A.I. of imazapyr would be entered in the first Total Pounds A.I./A.E. (Al AE #1) column. The pounds of A.I. of diuron would be entered in the second Total Pounds A.I./A.E. (AI AE #2) column. If an additional chemical was used in the mix it would be entered in the third Total Pounds A.I./A.E. (Al AE #3) column. Acres Treated: This should equal the Total Pounds A.I./A.E. divided by the Application Rate in Pounds A.I./A.E.

Upon termination of the development and production activities, the facility will be reclaimed, as outlined below: • All equipment and structures will be removed. • OXY will remove all safety and storm water BMPs, and other surface objects from the premises. • OXY will restore the site to pre -facility conditions by re -contouring and re - vegetating the site. Top soil will be redistributed across the site and will be reseeded with an approved seed mix (see attached seed mix recommendation). • OXY will monitor the site to ensure that 70 percent of the pre-existing vegetation is achieved, per the requirements of the area wide CDPHE Stormwater Permit for Cascade Creek and Collbran Developments. Seedbed Preparation and Slope Reconstruction: Cut and fill slopes will be backfilled and re-contoured to a slope of 3:1 — 2.5:1 or less in instances where necessary to match the existing natural contours. Following final contouring, all backfilled or ripped surfaces will be covered evenly with topsoil. Re - contouring should form a complex slope with heavy pocking. In areas with slope greater than 3 percent, imprinting of the seed bed is recommended. Final seedbed prep will consist of scarifying/imprinting the topsoil prior to seeding. Imprinting can be in the form of dozer tracks or furrows perpendicular to the direction of slope. When hydro -seeding or mulching, imprinting should be done prior to seeding, unless the mulch is to be crimped into the soil surface. If broadcast seeding and harrowing, imprinting will be done as part of the harrowing. Furrowing can be done by several methods, the most simple of which is to drill seed perpendicular to the direction of slope in a prepared bed. Other simple imprinting methods include deep hand raking and harrowing, always perpendicular to the direction of slope. All compacted areas will be ripped to depth of 18" with max furrow spacing of 2'. Where practicable, ripping will be conducted in two passes at perpendicular direction. Topsoil: Following final contouring, all backfilled or ripped surfaces will be covered evenly with topsoil. The topsoil in the cut slope on the back of the pad will be heavily pocked using the excavator bucket to form an uneven soil surface complex which will aid in revegetation and help with slope stabilization. The fill slope, and remaining disturbed, and reclaimed areas will be track walked to aid in revegetation and slope stabilization. In areas that may not have been disturbed during the reclamation process or areas of suspected compaction that will be reseeded, measures will be taken to loosen and spread the topsoil. These measures may include scarifying the soil by racking or harrowing the soil. Seed Mix: Seed mix used for reclamation will be taken from the attached seed mixtures. Seeding Procedures: For best results and success, the recommended grass mixture reseeding should be done in late autumn in order to take advantage of natural precipitation for the region. The reseeding rate should be doubled for broadcast application. Preferred seeding method is multiple seed bin rangeland drill with no soil preparation other than simple grading to slope and imprinting and waterbars, where applicable. Alternative seeding methods include, but are not limited to: • No -till -drill (no soil preparation required); • harrow with just enough soil moisture to create a rough surface, broadcast seed and reharrow, preferably at a 90 degree angle to the first harrow; • hydro -seeding (most economical in terms of seed cost); and • hand raking and broadcast followed by re -raking at a 90 degree angle to the first raking. • These are not the only means of replanting the site. However, these methods have been observed to be effective in similar landscapes. The prepared soils will be seeded (weather permitting) no more than 24 hours following completion of final seedbed preparation. The seeding will be conducted by means of drilling the prescribed seed at prescribed seeding rate. The seed will be drilled with a common range drill at a depth of 0.25 — 0.5" beneath the soil surface. The seed will be drilled horizontally across the pad faces and perpendicular to the track walking when possible. When slope gradient less than 2.5:1 exists and drilling is not possible from a mechanical and safety standpoint the soils will be broadcast seeded at twice the prescribed amount. The reseeding will be monitored and reseeded as appropriate until the reclamation standards detailed above are met.

Mineral Owners See Adjacent Property Owners section for complete list of Mineral Rights Owners. 3. Adjacent Land Use Land uses adjacent to the project site are predominately natural gas operations and seasonal cattle grazing. The project site is located within a 7,732.52 acre parcel. Land uses on adjacent properties also include natural gas and agricultural operations. 4. Site Features The proposed site is located at an approximate elevation of 8,300 feet above sea level and is in Section 16, Township 6 South, Range 97 West of the 6th P.M. The project area is located above Cascade Canyon and the Conn Creek drainage. Prior to being disturbed for a production pond, the site contained a mix of scrub -shrub upland habitat dominated by sagebrush and Gambel oak. 5. Soil Characteristics The soil at this location consists of 52-Northwater - Adel, 5 to 50 percent slopes and 57 - Parachute — Rhone, 5 to 30 percent slopes. The majority of the actual storage area is located on the 57 -Parachute -Rhone soil type. Both soil types are considered to exhibit "well drained" qualities with no frequency of flooding or ponding. Both soil types have low characteristics for corrosion of concrete and moderate corrosion of steel. The characteristics of these soils will not create significant restrictions on the development of a Centralized E & P Waste Management Facility. 760 Horizon Drive, Suite 102 TEL 970.263.7800 Grand Junction, CO 81506 FAX 970.263.7456 www.olssonassociates.com OXY USA WTP LP Pond G Facility 6. Geology and Hazard Topography The Oxy Pond G Facility consists of adjacent ponds that are being permitted as one facility. The site is shown on the U.S.G.S. Circle Dot Gulch 7.5 -minute topographic map. The facility is located near the rim of Cascade Canyon approximately 15 miles north of the town of De Beque in western Garfield County, Colorado. The site is located near the center of the Piceance Basin, an elongated, irregularly-shaped structural depression in the earth's crust resulting from tectonic forces associated with the uplift of the Rocky Mountains through geologic time. The general terrain surrounding the facility consists of rugged canyons incised into the Roan Cliffs. The present topography is the result of uplift combined with stream erosion. The erosion produced a series of high plateaus and deep valleys associated with the down cutting of Colorado River located to the south. The site is located approximately 550 feet northwest of an unnamed drainage to Cascade Canyon. The site lies at an elevation of approximately 8,260 feet above mean sea level. The elevation of Cascade Creek lies at more than 1,000 feet below the site elevation. Soils The proposed facility is underlain by soils mapped by the U.S. Natural Resources Conservation Service as the Parachute — Rhone loams, which are found on mountain sides and on ridge crests with 5 percent to 30 percent slopes, at elevations of 7,600 feet to 8,800 feet above mean sea level. The unit is about 55 percent Parachute soil and 35 percent Rhone loam. The two soils occur as areas so intricately intermingled that mapping them separately was deemed impractical at the scale used in the soil survey. The Parachute soil is moderately deep and is well drained. It formed in residuum derived dominantly from sandstone, siltstone, and shale. Typically the surface layer consists of grayish brown loam and is about ten inches thick; while the subsoil is brown very channery loam about 15 inches thick, with rippable, fractured siltstone encountered at depths of about 25 inches. Permeability is moderate in the Parachute soil, and the available water capacity is very low. Runoff is medium or rapid, and the hazard of water erosion is moderate to very severe. The Rhone loam is deep and well drained and is formed in residuum and colluvium derived predominantly from sandstone or shale. Typically the surface layer is brown channery loam about six inches thick, the subsoil is very dark grayish brown loam about 10 inches thick, and the next layer is a dark grayish brown channery loam about 29 inches thick, and the subsoil is brown very channery loam about 16 inches thick. Rippable, fractured siltstone is encountered at depths of about 55 inches. Permeability of the Rhone loam soils is moderate, and the available water capacity is also moderate. Runoff is medium or rapid, and the hazard of water erosion is moderate to very severe. Bedrock Geology The bedrock underlying the proposed facility is composed of the Tertiary age Uinta Formation or the Parachute Creek Member of the Green River Formation. The Uinta Formation consists of permeable, poorly sorted, fine to coarse sandstone with some Impact Analysis Page 2 OXY USA WTP LP Pond G Facility siltstone and mudstone, becoming more coarse-grained and permeable toward the top of the formation. The Uinta Formation and the Parachute Member of the upper part of the Green River Formation comprise the Uinta — Animas aquifer in the Piceance Basin. The Uinta Formation lies stratigraphically above the Tertiary age Parachute Member of the Green River Formation. The Parachute Creek Member consists primarily of dolomitic marlstone. Kerogen, a waxlike hydrocarbon, is present in some parts of the Parachute Creek Member in the Piceance and Uinta Basins. Marlstone containing large concentrations of kerogen is referred to as "oil shale" and is generally not as fractured and contains smaller concentrations of kerogen. Fractures and dissolution openings along fractures in the marlstone form the principal pathways for water movement in the aquifer (Robson and Banta, 1995). Oil shale is generally less permeable and forms confining units. The Mahogany zone is an oil shale bed within the Parachute Creek Member that is an example of a confining unit found within the Piceance Basin. A saline zone in the lower marlstone of the Parachute Creek Member is found within the central part of the Piceance Basin and contains the minerals nahcolite and halite, is not extensively fractured, and forms part of the relatively impermeable lower confining unit of the aquifer (Robson and Banta, 1995). The depth to the top of the Mahogany zone in the vicinity of the site is expected to lie at an elevation of 6,000 feet. The Garden Gulch Member, Anvil Points Member, and Douglas Creek Member of the Green River Formation and the Tertiary age Wasatch Formation forms a confining unit that separates the Uinta — Animas aquifer from the underlying upper Cretaceous Mesaverde aquifer. Local and Regional Geologic Structure The water storage facility is located on the southwestern limb of the Crystal Creek Anticline and the northeastern limb of the Clear Creek Syncline. The northwest trending fold system of the Crystal Creek anticlinal nose and the Clear Creek Syncline begins near the Colorado River and extends northward for approximately 30 miles into the southwestern part of the Piceance Creek Basin. A part of the Clear Creek syncline occupies the southwestern part of this area and the trace of its axis is closely parallel to that of the Crystal Creek anticline. The Clear Creek syncline is a broad shallow fold the trace of which closely parallels the axis of the Crystal Creek anticline. The Crystal Creek anticlinal nose forms the southeastern element of an anticlinal fold that trends across the southwest part of the Piceance Basin. The fold plunges to the northwest and terminates near the western boundary of the area in a structural saddle (Hail, 1992). The anticline is somewhat asymmetrical and has steeper dips on its southwest limb of about 200 feet per mile and gentler dips on its northeastern limb of about 65 feet per mile (Hail, 1992). No major faults are present in the project area. Two small groups of normal faults are present in the southern extent of the Roan Plateau with one set approximately 15 miles northeast and a second smaller group about 20 miles northwest of the project site (Hail, 1992). Impact Analysis Page 3 OXY USA WTP LP Pond G Facility Geologic Hazards There are no major faults in the central Roan Plateau area (Hail, 1992). Minimal seismic activity near the proposed disposal facility has occurred in recent geologic time. One earthquake of magnitude greater than 5.0 occurred in Garfield County since the early 1960s when proper instrumentation was implemented in the state of Colorado. The epicenter of this earthquake was approximately 17 miles southeast of the project site. A second recorded earthquake greater than 5.0 occurred in Rio Blanco County with an epicenter about 20 miles northwest of the project site. Mesa County has historically experienced few earthquakes. The USGS has rated Mesa County as having low to moderate earthquake hazard, although no specific seismic study has been done in Mesa County. According to the Colorado Geological Survey, no Quaternary -age faults are present in the Roan Plateau area (Widmann and others, 1998). However, the Geologic Map of Colorado (Tweeto, 1979) shows northeast -southwest trending normal faults exist in the Cretaceous bedrock near the Douglas Creek Arch and the western edge of the Piceance Basin. In addition, a series of normal faults trace along the eastern Piceance Basin boundary near the Grand Hogback to the east. Although faults are not always visible at the surface, this does not preclude the chance of an earthquake happening in the area at some point in the future. According to the Colorado Earthquake Hazard Mitigation Council (2008), "Earthquakes can also occur on faults that do not rupture the ground surface or on faults that are not yet recognized as being hazardous. These so called "random" earthquakes are considered in most hazard analyses to help account for faults that are not apparent at the earth's surface." No surficial geologic hazards (landslide, mudflow, fan) or soils hazards have been mapped in the immediate vicinity of the proposed facility. The site is not located in an area mapped as a floodplain hazard by the Federal Emergency Management Agency (FEMA). However, because of the natural slope above the property within the northeast - to -southwest oriented drainage, overland flow is possible in the event of an extreme precipitation event. Although records of extreme rainfall events are unavailable for locations on top of the Roan Plateau, climate records since the mid -20th century indicate that the record 24-hour rainfall amounts at Grand Junction, Palisade, and Parachute have not exceeded 2 inches (Western Regional Climate Center, 2011). The duration of these events within a 24 hour period is not known, and it is possible that a short burst of intense rainfall event could cause local overland flow in the watershed that encompasses the project site if a precipitation rate exceeds the infiltration rate of the watershed soils. The primary limitations for shallow excavations are based on the slopes and severe seepage. Consideration will be given to the design and construction of this facility to ensure that slopes are graded appropriately to minimize the potential for cutback caving. The suitability of the soils in the project area is identified as being somewhat to very limited in regard to the construction of ponds and embankments. The limitations identified are primarily applicable to unlined water impoundments. Consideration will be given to design and construction characteristics related to the area soil thickness and Impact Analysis Page 4 OXY USA WTP LP Pond G Facility depth to bedrock to mitigate these limitations. Consideration will also be given to the design and operation of the high density polyethylene (HDPE) liner system for the impoundments, which will mitigate potential seepage and leaks. Surface Water Features Surface water features within two miles of the project site include Cascade Canyon located approximately 1,660 feet to the southeast of the water treatment facility, and an unnamed tributary drainage to Cascade Canyon located approximately 550 feet to the southwest. The site lies on a drainage divide between Cascade Creek to the east and Conn Creek to the west - northwest. If a produced water spill were to occur and leave the site, it is expected that it would flow toward Cascade Canyon. The site is shown on the USGS 1:24,000 topographic map (Circle Dot Gulch Quadrangle). Cascade Creek has perennial flow, although no flow records are available to determine the flow conditions in these drainages. There are no springs shown in Section 16, Township 6 South, Range 97 West. Shallow Groundwater and Maior Aquifers Shallow groundwater is not expected to occur in close proximity to the site due to the site being located on a prominence of Cascade Canyon at an elevation of approximately 8,400 feet. Cascade Canyon is the nearest surface water and lies at elevations of 7,400 feet to 8,200 feet. Major aquifers in the area consist of the Uinta — Animas aquifer, and according to published geologic maps, the bedrock exposed at the surface consists of the Uinta Formation. The Uinta — Animas aquifer in the Piceance Basin consists of the Uinta Formation and the Parachute Creek Member of the Green River Formation. Much of the intergranular space in the sandstone and siltstone is filled by sodium and bicarbonate cements; however, fractures are numerous and produce substantial permeability. Water Wells within the Site Boundary According to the COGCC website and the Colorado Division of Water Resources there are no permitted water wells within Section 16, Township 6 South, Range 97 West. The nearest permitted water wells are located in Section 17, Township 6 South, Range 97 West, at a distance of a mile away from the site. These wells are monitoring wells owned by Oxy, at a lower elevation than the site, but are located cross gradient to the site and are located across the Conn Creek and Cascade Creek drainages. No springs are shown in Section 16 or Section 17; however springs are shown in Section 15 to the southeast across the Cascade Canyon. The springs are located at an elevation of less than 8,200 feet above mean sea level and are cross gradient from the site. Hydrologic Properties of Shallow Groundwater and Major Aquifers The Uinta — Animas aquifer in the Piceance Basin receives about 24,000 acre-feet per year of recharge, primarily in the upland areas near the margins of the aquifer. Discharge is approximately equal to recharge and primarily occurs in the valleys of Piceance Creek and other tributaries to the White River or in the valley of the Colorado River and its tributaries (Robson and Banta, 1995). Impact Analysis Page 5 OXY USA WTP LP Pond G Facility The permeability of the major formations in the Piceance Basin aquifers is relatively low. Permeability of the Uinta — Anima aquifer is dependent on the location and orientation of fractures. The potentiometric surface of the Uinta — Animas aquifer generally ranges from about 100 feet above land surface to 500 feet below land surface; the surface generally is near or above land surface in valleys in areas of groundwater discharge. Larger depths to water are more common in highland areas that are remote from streams or other sources of recharge (Robson and Banta, 1995). In the Piceance Basin, the potentiometric surface ranges in altitude from about 6,000 feet to 8,500 feet, and groundwater primarily flows toward the discharge areas along Piceance and Yellow Creeks (Robson and Banta, 1995). The total dissolved solids in the aquifer range from 500 milligrams per liter (mg/L) to 3,000 mg/L. Site Location in Relation to Nearby Floodplains The facility is not within a mapped FEMA flood hazard zone; however, it is located near the rim of the Cascade Creek canyon an area that may be prone to flash floods. The site is located within 1560 feet of Cascade Creek, but is at an elevation of 200 feet to 400 feet above the creek. The site is not subject to COGCC Rule 317B since it is not close to the segment of the Colorado River that supplies the town of De Beque with drinking water. Existing Shallow Groundwater Quality Baseline groundwater quality sampling should occur prior to facility construction or modification to document pre -development conditions at the project site, as data in the area is currently not available. The groundwater quality, where it is present, is expected to be relatively fresh to `bicarbonate' type groundwater. Potential for Impacts to Nearby Surface Water and Groundwater Cascade Creek could potentially be adversely impacted if a release from the facility were to reach it. Shallow groundwater resources are not expected at this location. The pond will be constructed with a HDPE plastic liner to prevent seepage. 7. Groundwater and Aquifer Recharge Areas The proposed project site is not located in any mapped floodplain. An individual septic disposal system (ISDS) will not be used at this site so soils will not have to support waste disposal. The site has been graded for use as a pond facility. BMPs will be implemented to control stormwater run-off and soil erosion. 8. Environmental Impacts a. Determination of long-term and short-term effects on flora and fauna The conversion of the site will not have a significant effect on the local flora and fauna. The site has been previously disturbed and graded for a pond facility. No critical wildlife habitat will be lost due to the conversion of the pad site to a centralized E & P waste facility. Noxious weeds will be controlled on the site during the life of the project. The site will be reclaimed after it is no longer required for natural gas production. Impact Analysis Page 6 OXY USA WTP LP Pond G Facility Oxy commissioned ERO Resources Corporation (ERO) to prepare a biological resources survey of the site and that report is included as an exhibit to this application. According to ERO, the site has the potential for only one federally threatened, proposed and candidate species to occur in the project area. ERO surveyed the project site for the potential habitat for the greater sage grouse. They found the area to be poor habitat for this species. This conclusion corresponds with the Suitable Habitat Results Map of the adopted Garfield County Greater Sage - Grouse Conservation Plan. The project area is not located in an elk winter concentration area. ERO determined that there are no raptor nests near the project area. The proposed site is within one- half mile of raptor cliff habitat. b. Determination of the effect on designated environmental resources, including critical Wildlife Habitat As stated above, the site has been previously disturbed and graded for a production pond. No critical wildlife habitat will be lost due to the conversion of the pond to an E & P waste facility. Noxious weeds will be controlled on the site during the life of the project. The site will be reclaimed after it is no longer required for natural gas production. c. Impacts on Wildlife and domestic animals through creation of hazardous attractions, alteration of existing native vegetation, blockade of migration routes, use patterns, or other disruptions The proposed storage area will not create hazardous attractions or alter existing native vegetation. The proposal will not block wildlife migration routes or use patterns. d. Evaluation of any potential radiation hazard that may have been identified by the State or County Health Departments The proposed site is not located on or near a Uranium Mine Tailings Radiation Control Act (UMTRCA) Site or other known radiation hazard site. Radon is a naturally occurring, odorless and colorless radioactive gas that is produced by the radioactive decay of radioactive minerals present in the soils and bedrock. According to the Colorado Department of Public Health and Environment (CDPHE), Colorado has a moderate to high radon potential. Since the site is a facility that does not have buildings or an area that is occupied throughout the work day, the potential presence of radon is not expected to represent a geologic hazard or a significant worker exposure issue. 9. Nuisance Adjacent lands will not be impacted by the generation of vapor, dust, smoke, glare or vibration. In accordance with Oxy's Fugitive Dust Mitigation Plan, water will be used for Impact Analysis Page 7 OXY USA WTP LP Pond G Facility dust suppression during construction and operation of the facility. Any lighting on-site will be down cast. 10. Hours of Operation The Pond G facility will be accessible to Oxy personnel 24 hours a day, year around. No personnel will be stationed at the facility on a regular basis.

This facility will be used to store produced water that would be recycled for well completions or eventually disposed of at a permitted facility. The facility is currently constructed as a production pond and OXY is requesting approval as an E & P facility. It is expected that the lifespan of the site will be approximately 30 years. The site is located approximately 24 travel miles north of the Exit 62 interchange of Highway I- 70 at DeBeque, Colorado. The facility is located in the Southeast 1/4 of the Northwest 1/4 of Section 16, Township 6 South, Range 97 West of the 6th Principal Meridian in unincorporated Garfield County. The subject site encompasses approximately 14.88 acres on a 7,732.52 acre parcel and is located at an elevation of 8,300 feet. The property is owned by and the facility is operated by Oxy. The objective of this analysis is to review the existing road network, provide traffic projections for the facility, determine trip distribution, and analyze the need for roadway modifications. EXISTING ROAD NETWORK This facility will be accessed from the 1-70 exit at DeBeque, Colorado. Vehicles traveling to the site will drive north through the Town of DeBeque and on Mesa County 45 Road (Roan Creek Road) for approximately 3.75 miles. The road continues and crosses the Garfield/Mesa County Line where the road transitions to Garfield County Road (CR) 204. Approximately 4.25 miles north of the county line vehicles will turn right onto CR 213 (Conn Creek Road) and travel approximately 4 miles to the end of the county road. From this point travel is on a series of private roads that were built and are maintained for the exclusive use of the natural gas industry. The facility is located an additional 12 miles up Cascade Creek and on the top of the Plateau. Both CR 204 and 213 are preferred haul routes according to maps available on the Garfield County web -site. Both of these roads are generally used for access to ranches and agricultural operations, rural residential uses, oil and gas operations and access to public lands managed by the BLM. According to the Garfield County Road Inventory Report, CR 204 is classified as Local road and is a two lane asphalt roadway with gravel shoulders. The 2011 Garfield County HUTF Report OXY Pond G Complex 1 April, 2013 Basic Traffic Analysis describes the roadway as is in good condition. The road has a posted speed limit of 45 mph. During 2002, Garfield County Road & Bridge conducted a traffic study of CR 204. The study concluded that there were 337 average trips per day (ADT) at that time. According to the Garfield County Road Inventory Report, CR 213 is classified as Local road and is a two lane road consisting of a section constructed of a combination of soil, gravel, and stone and a section consisting of graded and drained natural soil. The 2011 Garfield County HUTF Report describes the roadway as is in good condition. During 2002, Garfield County Road & Bridge conducted a traffic study for CR 213. The study concluded that there were 9 average trips per day at that time. There is a deceleration/turn lane for north bound traffic on CR 204 turning right onto CR 213. A stop sign controls west bound traffic on CR 213 at the intersection of that road with CR204. TRAFFIC PROJECTIONS Given the lack of data regarding traffic growth for this area, a conservative growth rate of 3% is assumed. This rate was applied to the existing counts to obtain background traffic for the forecast years of 2013 and 2043, respectively. These planning horizon years were chosen as they correspond with the expected life of the facility. This results in an estimated ADT of 446 in 2013 and a projected ADT of 1132 in 2043 for CR 204. The result for CR 213 in 2013 is an estimated ADT of 12 and a projected ADT of 30 in 2043 (Table 1). Table 1: Background Traffic Projections — Pond G Facility TRIP GENERATION AND DISTRIBUTION Trip generation is generally determined using rates found in the ITE Trip Generation manual. Rates from this publication are applied to values related to the size of the proposed site to estimate the trips expected to enter and exit the site. In this case, no rates are provided for facilities similar to these. To estimate trips expected for this site, information was gathered regarding the expected traffic based on the existing operations. Vehicle activities during daily operations will consist of one (1) pickup truck per day and one (1) transport truck every day.

Oxy Pond G Complex 2 April, 2013 Basic Traffic Analysis One (1) additional pickup truck and one (1) additional transport truck will be used for maintenance purposes each quarter. Trip generation will increase by three (3) pickup trucks and two (2) transport trucks per day and one (1) additional pickup truck and one (1) additional transport each month during periods of drilling and completion. Drilling and completion activities will occur periodically throughout the life of the project. The following Table 2 summarizes the expected average and maximum trips for the operational life of the facility. Table 2: Trip Generation — Pond G Facility Phase Average Trips/Day Maximum Trips/Day Percent Trucks Average Total Trips/Phase Phase Duration Operation 2 4 33 % 20,900 30 years Drilling & Completions 5 7 38.5% N/A N/A Combined 7 11 33% N/A N/A Based on the County's traffic study, OXY's Pond G facility related traffic will have a maximum 2.45% increase on daily traffic activity during operations, maintenance, drilling and completion activities associated with the facility in 2013 and will have a maximum 0.97% increase on daily traffic activity during 2043 on CR 204. The following Table 3 summarizes the expected percentage of trips this facility will generate on CR 204.

Additionally, the majority of traffic on this road is currently associated with the natural gas industry and the general public will not be impacted by the increase of traffic on this road. CONSTRUCTION PHASE The storage pond is currently built, and major excavation of the site will not be necessary. Only minor construction traffic will be generated by this project to bring the facility up to COGCC E&P Waste Management Facility standards. ROADWAY ANALYSIS Existing Parcel Current land use on the subject parcel is primarily natural gas development. The majority of existing traffic on CR 213 is related to natural gas development activities, very limited agricultural activities and very low density rural residential uses. State Highway Crossings and Access The roadway access to this site does not cross any highway right-of-ways managed by the Colorado Department of Transportation. CR 204 is accessed via Mesa County 45 Road which accesses the State of Colorado highway system at the 1-70, Exit 62, interchange at DeBeque, Colorado. This grade separated interchange access point is controlled by stop signs at the top of each exit ramp. Site distances are adequate in both directions at these control points. Additional traffic control is not needed at this location. US Highway 6 / 1-70 Frontage Road terminates at Mesa County 45 Road approximately 300 feet northwest of the DeBeque interchange. This intersection is controlled with a combination of stop Oxy Pond G Complex 4 April, 2013 Basic Traffic Analysis and yield signage on the state highway leg of the intersection. Traffic traveling to this site from 1-70 would have the right-of-way at this intersection. Additional improvements are not needed at this location. Railroad Crossings Mesa County 45 Road crosses under a main railroad line approximately 0.5 miles north of the 1-70. This line is generally used for the transport of freight, coal and passenger rail traffic. This railroad crossing is grade separated and warning signals are not present or warranted. The roadway access to this site does not cross any other active railroad right-of-ways. Additional improvements are not needed at this location. Intersection of CR 204 & 213 As noted above, there is a deceleration/turn lane for north bound traffic on CR 204 turning right onto CR 213. A stop sign controls west bound traffic on CR 213 at the intersection of that road with CR 204. Given the amount of traffic estimated to be generated from the proposed facility additional improvements at this intersection are not needed at this time. RECOMMENDATIONS Based on the expected trip generation rates discussed above, the increase in average daily traffic is not expected to be significant on roads generally used by the public. CR 204 will see only a minor increase in traffic. CR 213 will see a significant increase in traffic only because of a very low baseline of traffic volume. However, the total traffic volumes will remain very low and can be accommodated by the existing roadway. Additionally, the majority of traffic on this road is associated with the natural gas industry. The worst-case scenario is that there would be a minor increase in traffic which would peak during drilling and completion activities. Based on the results of the analysis, no mitigation is recommended for the facility. As mentioned in the Roadway Analysis, the addition of traffic generated by the proposed facility does not increase existing volumes to levels required for auxiliary lanes or other roadway modifications.

GENERAL RESOURCE PROTECTION STANDARDS SECTION 7-201. AGRICULTURAL LANDS A. No Adverse Affect to Agricultural Operations The applicant leases the parcel for seasonal cattle grazing on the property. The proposed use will not directly affect this operation. B. Domestic Animal Controls Dogs and other domestic animals will not be permitted on the property or allowed to interfere with livestock. C. Fences The site will be fenced. The facility will not impact livestock operations. D. Roads No new roads will be constructed to access this facility and the existing road will be maintained. E. Irrigation Ditches The proposed use will not impact irrigation ditches. SECTION 7-202. WILDLIFE HABITAT AREAS Oxy commissioned ERO Resources Corporation (ERO) to prepare a biological resources survey of the site and it is included as an attachment to this application. A. Buffers Visual or sound buffers are not necessary to screen structures or activity areas from habitat areas. The facility will be fenced with an eight -foot tall wildlife fence, and the pond will be netted to exclude water fowl from the facility. According to a Biological Resources Survey performed by ERO, the site has the potential for only one federally threatened, proposed and candidate species to occur in the project area. ERO surveyed the project site for the potential habitat for the greater sage grouse. They found the area to be poor habitat for the greater sage grouse. This conclusion corresponds with the Suitable Habitat Results map of the adopted Garfield County Greater Sage -Grouse Conservation Plan. B. Locational Controls of Land Disturbance The project area is currently disturbed after being previously developed as a production pond. No additional wildlife habitat disturbance will occur. According to the ERO survey, most wildlife species that are likely to occur in the project boundaries are adapted to human - caused disturbance. The conversion of the site to an E & P Waste Management facility should not alter current migration patterns. Standards Analysis Page 3 OXY USA WTP LP Pond G Facility C. Preservation of Native Vegetation The site will be reclaimed after the facility is no longer utilized and will be revegetated with native plant species. Noxious weeds will be controlled during the life of the facility and during the re-establishment of native plants. A Noxious Weed Management Plan specifically developed for this site is included with this application in the Grading and Drainage Plan section. D. Habitat Compensation No critical wildlife habitat will be disturbed in converting this site to an E & P facility. E. Domestic Animal Controls Domestic animals will not be kept on the site. SECTION 7-203. PROTECTION OF WATERBODIES A. Minimum Setback The proposed site will be more than 35 feet from the Typical and Ordinary High Water elevation of any waterbody. B. Structures Permitted in Setback There will not be any structures located in this setback area. C. Structures and Activity Prohibited in Buffer Zone There will not be any structures or activities located in the buffer zone. SECTION 7-204. DRAINAGE AND EROSION The site is an existing disturbed surface area. No additional surface disturbance is planned. BMPs will be used to protect waterbodies from stormwater runoff during the operation of this facility. This facility is more than 100 feet from a waterbody, and it does not create more than 10,000 square feet of impervious area outside of the pond area which is designed to accommodate precipitation within the maintained freeboard.

They highlight soil limitations that affect various land uses and provide information about the properties of the soils in the survey areas. Soil surveys are designed for many different users, including farmers, ranchers, foresters, agronomists, urban planners, community officials, engineers, developers, builders, and home buyers. Also, conservationists, teachers, students, and specialists in recreation, waste disposal, and pollution control can use the surveys to help them understand, protect, or enhance the environment. Various land use regulations of Federal, State, and local governments may impose special restrictions on land use or land treatment. Soil surveys identify soil properties that are used in making various land use or land treatment decisions. The information is intended to help the land users identify and reduce the effects of soil limitations on various land uses. The landowner or user is responsible for identifying and complying with existing laws and regulations. Although soil survey information can be used for general farm, local, and wider area planning, onsite investigation is needed to supplement this information in some cases. Examples include soil quality assessments (http://soils.usda.gov/sqi/) and certain conservation and engineering applications. For more detailed information, contact your local USDA Service Center (http://offices.sc.egov.usda.gov/locator/app? agency=nrcs) or your NRCS State Soil Scientist (http://soils.usda.gov/contact/ state_offices/). Great differences in soil properties can occur within short distances. Some soils are seasonally wet or subject to flooding. Some are too unstable to be used as a foundation for buildings or roads. Clayey or wet soils are poorly suited to use as septic tank absorption fields. A high water table makes a soil poorly suited to basements or underground installations. The National Cooperative Soil Survey is a joint effort of the United States Department of Agriculture and other Federal agencies, State agencies including the Agricultural Experiment Stations, and local agencies. The Natural Resources Conservation Service (NRCS) has leadership for the Federal part of the National Cooperative Soil Survey. Information about soils is updated periodically. Updated information is available through the NRCS Soil Data Mart Web site or the NRCS Web Soil Survey. The Soil Data Mart is the data storage site for the official soil survey information. The U.S. Department of Agriculture (USDA) prohibits discrimination in all its programs and activities on the basis of race, color, national origin, age, disability, and where applicable, sex, marital status, familial status, parental status, religion, sexual orientation, genetic information, political beliefs, reprisal, or because all or a part of an individual's income is derived from any public assistance program.

They include a description of the soils and miscellaneous areas and their location on the landscape and tables that show soil properties and limitations affecting various uses. Soil scientists observed the steepness, length, and shape of the slopes; the general pattern of drainage; the kinds of crops and native plants; and the kinds of bedrock. They observed and described many soil profiles. A soil profile is the sequence of natural layers, or horizons, in a soil. The profile extends from the surface down into the unconsolidated material in which the soil formed or from the surface down to bedrock. The unconsolidated material is devoid of roots and other living organisms and has not been changed by other biological activity. Currently, soils are mapped according to the boundaries of major land resource areas (MLRAs). MLRAs are geographically associated land resource units that share common characteristics related to physiography, geology, climate, water resources, soils, biological resources, and land uses (USDA, 2006). Soil survey areas typically consist of parts of one or more MLRA. The soils and miscellaneous areas in a survey area occur in an orderly pattern that is related to the geology, landforms, relief, climate, and natural vegetation of the area. Each kind of soil and miscellaneous area is associated with a particular kind of landform or with a segment of the landform. By observing the soils and miscellaneous areas in the survey area and relating their position to specific segments of the landform, a soil scientist develops a concept, or model, of how they were formed. Thus, during mapping, this model enables the soil scientist to predict with a considerable degree of accuracy the kind of soil or miscellaneous area at a specific location on the landscape. Commonly, individual soils on the landscape merge into one another as their characteristics gradually change. To construct an accurate soil map, however, soil scientists must determine the boundaries between the soils. They can observe only a limited number of soil profiles. Nevertheless, these observations, supplemented by an understanding of the soil -vegetation -landscape relationship, are sufficient to verify predictions of the kinds of soil in an area and to determine the boundaries. Soil scientists recorded the characteristics of the soil profiles that they studied. They noted soil color, texture, size and shape of soil aggregates, kind and amount of rock fragments, distribution of plant roots, reaction, and other features that enable them to identify soils. After describing the soils in the survey area and determining their properties, the soil scientists assigned the soils to taxonomic classes (units). Taxonomic classes are concepts. Each taxonomic class has a set of soil characteristics with precisely defined limits. The classes are used as a basis for comparison to classify soils systematically. Soil taxonomy, the system of taxonomic classification used in the United States, is based mainly on the kind and character of soil properties and the arrangement of horizons within the profile. After the soil scientists classified and named the soils in the survey area, they compared the 5 Custom Soil Resource Report individual soils with similar soils in the same taxonomic class in other areas so that they could confirm data and assemble additional data based on experience and research. The objective of soil mapping is not to delineate pure map unit components; the objective is to separate the landscape into landforms or landform segments that have similar use and management requirements. Each map unit is defined by a unique combination of soil components and/or miscellaneous areas in predictable proportions. Some components may be highly contrasting to the other components of the map unit. The presence of minor components in a map unit in no way diminishes the usefulness or accuracy of the data. The delineation of such landforms and landform segments on the map provides sufficient information for the development of resource plans. If intensive use of small areas is planned, onsite investigation is needed to define and locate the soils and miscellaneous areas. Soil scientists make many field observations in the process of producing a soil map. The frequency of observation is dependent upon several factors, including scale of mapping, intensity of mapping, design of map units, complexity of the landscape, and experience of the soil scientist. Observations are made to test and refine the soil - landscape model and predictions and to verify the classification of the soils at specific locations. Once the soil -landscape model is refined, a significantly smaller number of measurements of individual soil properties are made and recorded. These measurements may include field measurements, such as those for color, depth to bedrock, and texture, and laboratory measurements, such as those for content of sand, silt, clay, salt, and other components. Properties of each soil typically vary from one point to another across the landscape. Observations for map unit components are aggregated to develop ranges of characteristics for the components. The aggregated values are presented. Direct measurements do not exist for every property presented for every map unit component. Values for some properties are estimated from combinations of other properties. While a soil survey is in progress, samples of some of the soils in the area generally are collected for laboratory analyses and for engineering tests. Soil scientists interpret the data from these analyses and tests as well as the field -observed characteristics and the soil properties to determine the expected behavior of the soils under different uses. Interpretations for all of the soils are field tested through observation of the soils in different uses and under different levels of management. Some interpretations are modified to fit local conditions, and some new interpretations are developed to meet local needs. Data are assembled from other sources, such as research information, production records, and field experience of specialists. For example, data on crop yields under defined levels of management are assembled from farm records and from field or plot experiments on the same kinds of soil. Predictions about soil behavior are based not only on soil properties but also on such variables as climate and biological activity. Soil conditions are predictable over long periods of time, but they are not predictable from year to year. For example, soil scientists can predict with a fairly high degree of accuracy that a given soil will have a high water table within certain depths in most years, but they cannot predict that a high water table will always be at a specific level in the soil on a specific date. After soil scientists located and identified the significant natural bodies of soil in the survey area, they drew the boundaries of these bodies on aerial photographs and identified each as a specific map unit. Aerial photographs show trees, buildings, fields, roads, and rivers, all of which help in locating boundaries accurately. 6 Soil Map The soil map section includes the soil map for the defined area of interest, a list of soil map units on the map and extent of each map unit, and cartographic symbols displayed on the map.

The map unit descriptions, along with the maps, can be used to determine the composition and properties of a unit. A map unit delineation on a soil map represents an area dominated by one or more major kinds of soil or miscellaneous areas. A map unit is identified and named according to the taxonomic classification of the dominant soils. Within a taxonomic class there are precisely defined limits for the properties of the soils. On the landscape, however, the soils are natural phenomena, and they have the characteristic variability of all natural phenomena. Thus, the range of some observed properties may extend beyond the limits defined for a taxonomic class. Areas of soils of a single taxonomic class rarely, if ever, can be mapped without including areas of other taxonomic classes. Consequently, every map unit is made up of the soils or miscellaneous areas for which it is named and some minor components that belong to taxonomic classes other than those of the major soils. Most minor soils have properties similar to those of the dominant soil or soils in the map unit, and thus they do not affect use and management. These are called noncontrasting, or similar, components. They may or may not be mentioned in a particular map unit description. Other minor components, however, have properties and behavioral characteristics divergent enough to affect use or to require different management. These are called contrasting, or dissimilar, components. They generally are in small areas and could not be mapped separately because of the scale used. Some small areas of strongly contrasting soils or miscellaneous areas are identified by a special symbol on the maps. If included in the database for a given area, the contrasting minor components are identified in the map unit descriptions along with some characteristics of each. A few areas of minor components may not have been observed, and consequently they are not mentioned in the descriptions, especially where the pattern was so complex that it was impractical to make enough observations to identify all the soils and miscellaneous areas on the landscape. The presence of minor components in a map unit in no way diminishes the usefulness or accuracy of the data. The objective of mapping is not to delineate pure taxonomic classes but rather to separate the landscape into landforms or landform segments that have similar use and management requirements. The delineation of such segments on the map provides sufficient information for the development of resource plans. If intensive use of small areas is planned, however, onsite investigation is needed to define and locate the soils and miscellaneous areas. 10 Custom Soil Resource Report An identifying symbol precedes the map unit name in the map unit descriptions. Each description includes general facts about the unit and gives important soil properties and qualities. Soils that have profiles that are almost alike make up a soil series. Except for differences in texture of the surface layer, all the soils of a series have major horizons that are similar in composition, thickness, and arrangement. Soils of one series can differ in texture of the surface layer, slope, stoniness, salinity, degree of erosion, and other characteristics that affect their use. On the basis of such differences, a soil series is divided into soil phases. Most of the areas shown on the detailed soil maps are phases of soil series. The name of a soil phase commonly indicates a feature that affects use or management. For example, Alpha silt loam, 0 to 2 percent slopes, is a phase of the Alpha series. Some map units are made up of two or more major soils or miscellaneous areas. These map units are complexes, associations, or undifferentiated groups. A complex consists of two or more soils or miscellaneous areas in such an intricate pattern or in such small areas that they cannot be shown separately on the maps. The pattern and proportion of the soils or miscellaneous areas are somewhat similar in all areas. Alpha -Beta complex, 0 to 6 percent slopes, is an example. An association is made up of two or more geographically associated soils or miscellaneous areas that are shown as one unit on the maps. Because of present or anticipated uses of the map units in the survey area, it was not considered practical or necessary to map the soils or miscellaneous areas separately. The pattern and relative proportion of the soils or miscellaneous areas are somewhat similar. Alpha - Beta association, 0 to 2 percent slopes, is an example. An undifferentiated group is made up of two or more soils or miscellaneous areas that could be mapped individually but are mapped as one unit because similar interpretations can be made for use and management. The pattern and proportion of the soils or miscellaneous areas in a mapped area are not uniform. An area can be made up of only one of the major soils or miscellaneous areas, or it can be made up of all of them. Alpha and Beta soils, 0 to 2 percent slopes, is an example. Some surveys include miscellaneous areas. Such areas have little or no soil material and support little or no vegetation. Rock outcrop is an example. 11 Custom Soil Resource Report Douglas -Plateau Area, Colorado, Parts of Garfield and Mesa Counties 52—Northwater-Adel complex, 5 to 50 percent slopes Map Unit Setting

displayed as thematic maps with a summary table for the soil map units in the selected area of interest. A single value or rating for each map unit is generated by aggregating the interpretive ratings of individual map unit components. This aggregation process is defined for each interpretation. Building Site Development Building site development interpretations are designed to be used as tools for evaluating soil suitability and identifying soil limitations for various construction purposes. As part of the interpretation process, the rating applies to each soil in its described condition and does not consider present land use. Example interpretations can include corrosion of concrete and steel, shallow excavations, dwellings with and without basements, small commercial buildings, local roads and streets, and lawns and landscaping. Corrosion of Steel "Risk of corrosion" pertains to potential soil -induced electrochemical or chemical action that corrodes or weakens uncoated steel. The rate of corrosion of uncoated steel is related to such factors as soil moisture, particle -size distribution, acidity, and electrical conductivity of the soil. Special site examination and design may be needed if the combination of factors results in a severe hazard of corrosion. The steel in installations that intersect soil boundaries or soil layers is more susceptible to corrosion than the steel in installations that are entirely within one kind of soil or within one soil layer. The risk of corrosion is expressed as "low," "moderate," or "high." 15 39° 31' 40" 39° 31' 26" 738050 738100 Custom Soil Resource Report Map—Corrosion of Steel 738150 738200 738250 738300 738350 o 0 0 0 o O s- .rn CO M O 0 N 0) OD rn —co00— M r CO a V O o O O O o, coco V V O O LO LO OJ OJ M. .oJ r C -- OD M CO m- d OD 71 - CO CJ OJT CO 0) 738050 108° 13'50" 738100 738150 738200 Map Scale: 1:1,980 if printed on Asize (8.5" x 11") sheet.

A map unit is typically composed of one or more "components". A component is either some type of soil or some nonsoil entity, e.g., rock outcrop. For the attribute being aggregated, the first step of the aggregation process is to derive one attribute value for each of a map unit's components. From this set of component attributes, the next step of the aggregation process derives a single value that represents the map unit as a whole. Once a single value for each map unit is derived, a thematic map for soil map units can be rendered. Aggregation must be done because, on any soil map, map units are delineated but components are not. For each of a map unit's components, a corresponding percent composition is recorded. A percent composition of 60 indicates that the corresponding component typically makes up approximately 60% of the map unit. Percent composition is a critical factor in some, but not all, aggregation methods. The aggregation method "Dominant Condition" first groups like attribute values for the components in a map unit. For each group, percent composition is set to the sum of the percent composition of all components participating in that group. These groups now represent "conditions" rather than components. The attribute value associated with the group with the highest cumulative percent composition is returned. If more than one group shares the highest cumulative percent composition, the corresponding "tie-break" rule determines which value should be returned. The "tie-break" rule indicates whether the lower or higher group value should be returned in the case of a percent composition tie. The result returned by this aggregation method represents the dominant condition throughout the map unit only when no tie has occurred. Component Percent Cutoff: None Specified Components whose percent composition is below the cutoff value will not be considered. If no cutoff value is specified, all components in the database will be considered. The data for some contrasting soils of minor extent may not be in the database, and therefore are not considered. 18 Custom Soil Resource Report Tie-break Rule: Higher The tie-break rule indicates which value should be selected from a set of multiple candidate values, or which value should be selected in the event of a percent composition tie. Corrosion of Concrete "Risk of corrosion" pertains to potential soil -induced electrochemical or chemical action that corrodes or weakens concrete. The rate of corrosion of concrete is based mainly on the sulfate and sodium content, texture, moisture content, and acidity of the soil. Special site examination and design may be needed if the combination of factors results in a severe hazard of corrosion. The concrete in installations that intersect soil boundaries or soil layers is more susceptible to corrosion than the concrete in installations that are entirely within one kind of soil or within one soil layer. The risk of corrosion is expressed as "low," "moderate," or "high." 19 Custom Soil Resource Report MAP LEGEND MAP INFORMATION Area of Interest (AOI) Map Scale: 1:1,980 if printed on A size (8.5" x 11") sheet.

Water Features Water Features include ponding frequency, flooding frequency, and depth to water table. Flooding Frequency Class Flooding is the temporary inundation of an area caused by overflowing streams, by runoff from adjacent slopes, or by tides. Water standing for short periods after rainfall or snowmelt is not considered flooding, and water standing in swamps and marshes is considered ponding rather than flooding. Frequency is expressed as none, very rare, rare, occasional, frequent, and very frequent. "None" means that flooding is not probable. The chance of flooding is nearly 0 percent in any year. Flooding occurs less than once in 500 years. "Very rare" means that flooding is very unlikely but possible under extremely unusual weather conditions. The chance of flooding is less than 1 percent in any year. "Rare" means that flooding is unlikely but possible under unusual weather conditions. The chance of flooding is 1 to 5 percent in any year. "Occasional" means that flooding occurs infrequently under normal weather conditions. The chance of flooding is 5 to 50 percent in any year. "Frequent" means that flooding is likely to occur often under normal weather conditions. The chance of flooding is more than 50 percent in any year but is less than 50 percent in all months in any year. "Very frequent" means that flooding is likely to occur very often under normal weather conditions. The chance of flooding is more than 50 percent in all months of any year. 24 Custom Soil Resource Report MAP LEGEND MAP INFORMATION Area of Interest (AOI) Map Scale: 1:1,980 if printed on A size (8.5" x 11") sheet.

A map unit is typically composed of one or more "components". A component is either some type of soil or some nonsoil entity, e.g., rock outcrop. For the attribute being aggregated, the first step of the aggregation process is to derive one attribute value for each of a map unit's components. From this set of component attributes, the next step of the aggregation process derives a single value that represents the map unit as a whole. Once a single value for each map unit is derived, a thematic map for soil map units can be rendered. Aggregation must be done because, on any soil map, map units are delineated but components are not. For each of a map unit's components, a corresponding percent composition is recorded. A percent composition of 60 indicates that the corresponding component typically makes up approximately 60% of the map unit. Percent composition is a critical factor in some, but not all, aggregation methods. The aggregation method "Dominant Condition" first groups like attribute values for the components in a map unit. For each group, percent composition is set to the sum of the percent composition of all components participating in that group. These groups now represent "conditions" rather than components. The attribute value associated with the group with the highest cumulative percent composition is returned. If more than one group shares the highest cumulative percent composition, the corresponding "tie-break" rule determines which value should be returned. The "tie-break" rule indicates whether the lower or higher group value should be returned in the case of a percent composition tie. The result returned by this aggregation method represents the dominant condition throughout the map unit only when no tie has occurred. Component Percent Cutoff: None Specified Components whose percent composition is below the cutoff value will not be considered. If no cutoff value is specified, all components in the database will be considered. The data for some contrasting soils of minor extent may not be in the database, and therefore are not considered. 27 Custom Soil Resource Report Tie-break Rule: More Frequent The tie-break rule indicates which value should be selected from a set of multiple candidate values, or which value should be selected in the event of a percent composition tie.

According to Article 4: Application and Review Procedures 4-203 Description of Submittal Requirements A. Professional Qualifications The professional qualifications for preparation and certification of certain documents is required by the Garfield County LUDC, and require that "Geology reports shall be prepared by either a member of the American Institute of Professional Geologists, a member of the Association of Engineering Geologists, or a qualified geotechnical engineer licensed in the state of Colorado." Garfield County LUDC 2013 Article 7-207 requires an assessment of Natural and Geologic Hazards as part of the SUP submittal. Garfield County defines a geologic hazard as "A geologic phenomenon that is so adverse to past, current, or foreseeable construction or land use as to constitute a significant hazard to public health and safety or to property." This term includes, but is not limited to avalanches, landslides, rock falls, mudflows, unstable or potentially unstable soils, seismic effects, radioactivity, and ground subsidence. This summary presents an assessment of geologic hazards potentially present in the vicinity of the OXY Pond G centralized E&P Waste Management Facility. Currently the state of Colorado does not require licensure or registration of geologists. However, Colorado Revised Statutes do require that geologic reports be prepared or authorized by a professional geologist. Professional Geologist is a term defined in Colorado Statutes. The references for these laws are shown here: 34-1-201. Definitions. As used in this part 2, unless the context otherwise requires: (1) "Geologist" means a person engaged in the practice of geology. (2) "Geology" means the science which treats of the earth in general; the earth's processes and its history; investigation of the earth's crust and the rocks and other materials which compose it; and the applied science of utilizing knowledge of the earth's history, processes, constituent rocks, minerals, liquids, gases, and other materials for the use of mankind. (3) "Professional geologist" is a person who is a graduate of an institution of higher education which is accredited by a regional or national accrediting agency, with a minimum of thirty semester hours (forty-five quarter) hours of undergraduate or graduate work in a field of geology and whose post baccalaureate training has been in the field of geology with a specific record of an additional five years of geological experience to include no more than two years of graduate work. (4) 34-1-202. Reports containing geologic information. Any report required by law or by rule and regulation, and prepared as a result of or based on a geologic study or on geologic data, or which contains information relating to geology, as defined in section 34-1-201 (2), and which is to be presented for any state agency, political subdivision of the state, or recognized state or local board or commission, shall be prepared or approved by a professional geologist as defined in section 34-1-201(3). Professional Geologist Certification By means of this certification, I attest that: - Although the Colorado Geological Survey does not currently have a licensing or registration program for professional geologists practicing in the state of Colorado, there are requirements within local and State statutes that require that geologic reports be prepared by a professional geologist. I attest that I meet the requirements of the Colorado Geological Survey's definition of a professional geologist having completed and met the educational requirements of the Colorado Geological Survey definition; - I am qualified to prepare a Natural and Geologic Hazard Summary in accordance with the provisions of Garfield County Colorado LUDC 2013; - I have reviewed published geologic reports and geologic maps prepared by the CGS and United States Geologic Survey (USGS), and others related to geologic conditions or hazards potentially present in the project area; - The conclusions and recommendations contained in this report are based on information available and known to me at the time of this report. Good scientific principles and standard engineering practices were taken into consideration in arriving at the conclusions and recommendations made in this report. James W. Hix Senior Geologist Date: 08/01/2013 Note: The PG's certification does not relieve the owner/operator of the facility of the duty of fully implementing the recommendations in accordance with all applicable Federal, State, and local requirements in order to achieve the desired goals or objectives. Form 28 - Centralized E&P Waste Management Facility Permit Application for COGCC ID #414402 Oxy Pond G Centralized E&P Waste Management Facility SE NW Section 16, T6S, R97W, 6th P.M., Garfield County, Colorado Rule 908.b (4) Topography The Oxy Pond G Centralized E&P Waste Management Facility consists of adjacent ponds that are being permitted as one facility. The site is shown on the U.S.G.S. Circle Dot Gulch 7.5 - minute topographic map. The facility is located near the rim of Cascade Canyon approximately 15 miles north of the town of De Beque in western Garfield County, Colorado. The site is located near the center of the Piceance Basin, an elongated, irregularly- shaped structural depression in the earth's crust resulting from tectonic forces associated with the uplift of the Rocky Mountains through geologic time. The general terrain surrounding the facility consists of rugged canyons incised into the Roan Cliffs. The present topography is the result of uplift combined with stream erosion. The erosion produced a series of high plateaus and deep valleys associated with the down cutting of Colorado River located to the south. The site is located approximately 550 feet northwest of an unnamed drainage to Cascade Canyon. The site lies at an elevation of approximately 8,260 feet above mean sea level. The elevation of Cascade Creek lies at more than 1,000 feet below the site elevation. Soils (Rule 908.b (7).A.i) The proposed facility is underlain by soils mapped by the U.S. Natural Resources Conservation Service as the Parachute — Rhone loams, which are found on mountain sides and on ridge crests with 5 percent to 30 percent slopes, at elevations of 7,600 feet to 8,800 feet above mean sea level. The unit is about 55 percent Parachute soil and 35 percent Rhone loam. The two soils occur as areas so intricately intermingled that mapping them separately was deemed impractical at the scale used in the soil survey. Please refer to the Pond G Complex Soils Map. The Parachute soil is moderately deep and is well drained. It formed in residuum derived dominantly from sandstone, siltstone, and shale. Typically the surface layer consists of grayish brown loam and is about ten inches thick; while the subsoil is brown very channery loam about 15 inches thick, with rippable, fractured siltstone encountered at depths of about 25 inches. Permeability is moderate in the Parachute soil, and the available water capacity is very low. Runoff is medium or rapid, and the hazard of water erosion is moderate to very severe. The Rhone loam is deep and well drained and is formed in residuum and colluvium derived from predominantly from sandstone or shale. Typically the surface layer is brown channery loam about six inches thick, the subsoil is very dark grayish brown loam about 10 inches thick, and Geohydrology Report Page 1 the next layer is a dark grayish brown channery loam about 29 inches thick, and the subsoil is brown very channery loam about 16 inches thick. Rippable, fractured siltstone is encountered at depths of about 55 inches. Permeability of the Rhone loam soils is moderate and the available water capacity is also moderate. Runoff is medium or rapid, and the hazard of water erosion is moderate to very severe. Bedrock Geology (Rule 908.b (7).A.ii) The bedrock underlying the proposed facility is composed of the Tertiary age Uinta Formation or the Parachute Creek Member of the Green River Formation. The Uinta Formation consists of permeable, poorly sorted, fine to coarse sandstone with some siltstone and mudstone, becoming more coarse-grained and permeable toward the top of the formation. The Uinta Formation and the Parachute Member of the upper part of the Green River Formation comprise the Uinta — Animas aquifer in the Piceance Basin. Please refer to the Pond G Complex Geology Map. The Uinta Formation lies stratigraphically above the Tertiary age Parachute Member of the Green River Formation. The Parachute Creek Member consists primarily of dolomitic marlstone. Kerogen, a waxlike hydrocarbon, is present in some parts of the Parachute Creek Member in the Piceance and Uinta Basins. Marlstone containing large concentrations of kerogen is referred to as "oil shale" and is generally not as fractured and contains smaller concentrations of kerogen. Fractures and dissolution openings along fractures in the marlstone form the principal pathways for water movement in the aquifer (Robson and Banta, 1995). Oil shale is generally less permeable and forms confining units. The Mahogany zone is an oil shale bed within the Parachute Creek Member that is an example of a confining unit found within the Piceance Basin. A saline zone in the lower marlstone of the Parachute Creek Member is found within the central part of the Piceance Basin and contains the minerals nahcolite and halite, is not extensively fractured, and forms part of the relatively impermeable lower confining unit of the aquifer (Robson and Banta, 1995). The depth to the top of the Mahogany zone in the vicinity of the site is expected to lie at an elevation of 6,000 feet. The Garden Gulch Member, Anvil Points Member, and Douglas Creek Member of the Green River Formation and the Tertiary age Wasatch Formation forms a confining unit that separates the Uinta — Animas aquifer from the underlying upper Cretaceous Mesaverde aquifer. Local and Regional Geologic Structures (Rule 908.b (7).A.iii) The Pond G facility is located on the southwestern limb of the Crystal Creek Anticline and the northeastern limb of the Clear Creek Syncline. The northwest trending fold system of the Crystal Creek anticlinal nose and the Clear Creek Syncline begins near the Colorado River and extends northward for approximately 30 miles into the southwestern part of the Piceance Creek Basin. A part of the Clear Creek syncline occupies the southwestern part of this area and the trace of its axis is closely parallel to that of the Crystal Creek anticline. The Clear Creek syncline is a broad shallow fold the trace of which closely parallels the axis of the Crystal Creek Geohydrology Report Page 2 anticline. The Crystal Creek anticlinal nose forms the southeastern element of an anticlinal fold that trends across the southwest part of the Piceance Basin. The fold plunges to the northwest and terminates near the western boundary of the area in a structural saddle (Hail, 1992). The anticline is somewhat asymmetrical and has steeper dips on its southwest limb of about 200 feet per mile and gentler dips on its northeastern limb of about 65 feet per mile (Hail, 1992). No major faults are present in the project area. Two small groups of normal faults are present in the southern extent of the Roan Plateau with one set approximately 15 miles northeast and a second smaller group about 20 miles northwest of the project site (Hail, 1992). Geologic Hazards (Rule 908.b (7).A.i) There are no major faults in the central Roan Plateau area (Hail, 1992). Minimal seismic activity near the proposed disposal facility has occurred in recent geologic time. One earthquake of magnitude greater than 5.0 occurred in Garfield County since the early 1960s when proper instrumentation was implemented in the state of Colorado. The epicenter of this earthquake was approximately 17 miles southeast of the project site. A second recorded earthquake greater than 5.0 occurred in Rio Blanco County with an epicenter about 20 miles northwest of the project site. Mesa County has historically experienced few earthquakes. The USGS has rated Mesa County as having low to moderate earthquake hazard, although no specific seismic study has been done in Mesa County. According to the Colorado Geological Survey, no Quaternary -age faults are present in the Roan Plateau area (Widmann and others, 1998). However, the Geologic Map of Colorado (Tweto, 1979) shows northeast -southwest trending normal faults exist in the Cretaceous bedrock near the Douglas Creek Arch and the western edge of the Piceance Basin. In addition, a series of normal faults trace along the eastern Piceance Basin boundary near the Grand Hogback to the east. Although faults are not always visible at the surface, this does not preclude the chance of an earthquake happening in the area at some point in the future. According to the Colorado Earthquake Hazard Mitigation Council (2008), "Earthquakes can also occur on faults that do not rupture the ground surface or on faults that are not yet recognized as being hazardous. These so called "random" earthquakes are considered in most hazard analyses to help account for faults that are not apparent at the earth's surface." No surficial geologic hazards (landslide, mudflow, fan) or soils hazards have been mapped in the immediate vicinity of the proposed facility. The site is not located in an area mapped as a floodplain hazard by the Federal Emergency Management Agency (FEMA). However, because of the natural slope above the property within the northeast -to -southwest oriented drainage, overland flow is possible in the event of an extreme precipitation event. Although records of extreme rainfall events are unavailable for locations on top of the Roan Plateau, climate records since the mid -20th century indicate that the record 24-hour rainfall amounts at Grand Junction, Palisade, and Parachute have not exceeded 2 inches (Western Regional Climate Center, 2011). The duration of these events within a 24 hour period is not known, and it is possible that a short Geohydrology Report Page 3 burst of intense rainfall event could cause local overland flow in the watershed that encompasses the project site if a precipitation rate exceeds the infiltration rate of the watershed soils. The primary limitations for shallow excavations are based on the slopes and severe seepage. Consideration will be given to the design and construction of this facility to ensure that slopes are graded appropriately to minimize the potential for cutback caving. The suitability of the soils in the project area is identified as being somewhat to very limited in regard to the construction of ponds and embankments. The limitations identified are primarily applicable to unlined water impoundments. Consideration will be given to design and construction characteristics related to the area soil thickness and depth to bedrock to mitigate these limitations. Consideration will also be given to the design and operation of the high density polyethylene (HDPE) liner system for the impoundments, which will mitigate potential seepage and leaks. Surface Water Features (Rule 908.b (7).B.i) Surface water features within two miles of the project site include Cascade Canyon located approximately 1,660 feet to the southeast of the water treatment facility, and an unnamed tributary drainage to Cascade Canyon located approximately 550 feet to the southwest. The site lies on a drainage divide between Cascade Creek to the east and Conn Creek to the west - northwest. If a produced water spill were to occur and leave the site, it is expected that it would flow toward Cascade Canyon. Please refer to the Pond G Complex Surface Water Map. The site is shown on the USGS 1:24,000 topographic map (Circle Dot Gulch Quadrangle). Cascade Creek has perennial flow, although no flow records are available to determine the flow conditions in these drainages. There are no springs shown in Section 16, Township 6 South, Range 97 West. Shallow Groundwater and Major Aquifers (Rule 908.b (7).B.ii) Shallow groundwater is not expected to occur in close proximity to the site due to the site being located on a prominence of Cascade Canyon at an elevation of approximately 8,400 feet. Cascade Canyon is the nearest surface water and lies at elevations of 7,400 feet to 8,200 feet. Major aquifers in the area consist of the Uinta — Animas aquifer, and according to published geologic maps, the bedrock exposed at the surface consists of the Uinta Formation. The Uinta — Animas aquifer in the Piceance Basin consists of the Uinta Formation and the Parachute Creek Member of the Green River Formation. Much of the intergranular space in the sandstone and siltstone is filled by sodium and bicarbonate cements; however, fractures are numerous and produce substantial permeability. Water Wells within the Site Boundary (Rule 908.b (7).B.iii) According to the COGCC website and the Colorado Division of Water Resources, there are no permitted water wells within Section 16, Township 6 South, Range 97 West. The nearest Geohydrology Report Page 4 permitted water wells are located in Section 17, Township 6 South, Range 97 West, at a distance of a mile away from the site. These wells are monitoring wells owned by OXY USA WTP LP, at lower elevation than the site, but are located cross gradient to the site and are located across the Conn Creek and Cascade Creek drainages. No springs are shown in Section 16 or Section 17; however springs are shown in Section 15 to the southeast across the Cascade Canyon. The springs are located at an elevation of less than 8,200 feet above mean sea level and are cross gradient from the site. Hydrologic Properties of Shallow Groundwater and Major Aquifers (Rule 908.b (7).B.iv) The Uinta — Animas aquifer in the Piceance Basin receives about 24,000 acre-feet per year of recharge, primarily in the upland areas near the margins of the aquifer. Discharge is approximately equal to recharge and primarily occurs in the valleys of Piceance Creek and other tributaries to the White River or in the valley of the Colorado River and its tributaries (Robson and Banta, 1995). The permeability of the major formations in the Piceance Basin aquifers is relatively low. Permeability of the Uinta — Anima aquifer is dependent on the location and orientation of fractures. The potentiometric surface of the Uinta — Animas aquifer generally ranges from about 100 feet above land surface to 500 feet below land surface; the surface generally is near or above land surface in valleys in areas of groundwater discharge. Larger depths to water are more common in highland areas that are remote from streams or other sources of recharge (Robson and Banta, 1995). In the Piceance Basin, the potentiometric surface ranges in altitude from about 6,000 feet to 8,500 feet, and groundwater primarily flows toward the discharge areas along Piceance and Yellow Creeks (Robson and Banta, 1995). The total dissolved solids in the aquifer range from 500 milligrams per liter (mg/L) to 3,000 mg/L. Site Location in Relation to Nearby Floodplains (Rule 908.b (7).B.v) The facility is not within a mapped FEMA flood hazard zone; however, it is located near the rim of the Cascade Creek canyon an area that may be prone to flash floods. The site is located within 1560 feet of Cascade Creek, but is at an elevation of 200 feet to 400 feet above the creek. The site is not subject to COGCC Rule 317B since it is not close to the segment of the Colorado River that supplies the town of De Beque with drinking water. The nearest mapped floodplains are approximately 12 miles to the south. Please refer to the Pond G Complex Floodplain Map. Existing Shallow Groundwater Quality (Rule 908.b (7).B.vi) Baseline groundwater quality sampling should occur prior to facility construction or modification to document pre -development conditions at the project site, as data in the area is currently not available. The groundwater quality, where it is present, is expected to be relatively fresh to `bicarbonate' type groundwater. Geohydrology Report Page 5 Potential for Impacts to Nearby Surface Water and Groundwater (Rule 908.b (7).B.vii) Cascade Creek could potentially be adversely impacted if a release from the facility were to reach it. Shallow groundwater resources are not expected at this location. The pond will be constructed with a HDPE plastic liner to prevent seepage.

The survey area is located approximately 10 miles north of DeBeque in Garfield County, Colorado. Location and Project Activities The survey area, which includes a uniform 0.5 -mile buffer around the existing project envelope, is located in southern Garfield County, Colorado (Figure 1). The legal location description of the approximate center of the project area is Section 16, Township 6 South, Range 97 West of the 6th PM; UTM NAD 83 Zone 12N, 783213m Easting, 4378834m Northing; Latitude, Longitude: 39.526480°N, -108.228776°W; USGS Circle Dot Gulch, CO Quadrangle. Oxy is the surface owner. An existing waste water pond occupies the site. The Pond G facility is fenced to exclude wildlife and for site security, and flagging deterrents have been installed to discourage birds from accessing the pond. Oxy proposes to made site modifications to improve long-term capacity and conditions at Pond G. There is no proposed change in disturbance footprint or type, timing, or number of vehicles accessing the site. The site is currently manned intermittently, as needed to support completion activities and would continue with this level of staffing based on activity level. The Pond G location is checked once per day for routine monitoring. The following modifications and activities are proposed within the existing previously disturbed footprint: 1. Drain, clean, and inspect the liner; make repairs as necessary; 2. Hydro -test for leaks; and 3. Drill 3 new groundwater monitoring wells. Activities 1 and 2 would require a total of about 3 weeks to complete. Activity 3 Durango would require about one week to complete. 1015'''/ Main Avenue Durango, CO 81301 970.422.2136 Setting Pond G occurs on a south-southeast aspect at an approximate elevation of 8,300 Western Slope feet above sea level (Figure 2).

Sources: USFWS 2013 There is potential for one species with ESA "candidate status" — greater sage - grouse (Centrocercus minimus) — to occur near the project area. According to the Colorado Oil and Gas Conservation Commission (COGCC) maps developed by Colorado Parks and Wildlife (CPW), the project area is adjacent to a greater sage grouse production area (COGCC 2013, CPW 2013; ERO Figure 3). Most of the project area is disturbed, with graded slopes, pad/pond areas, facilities, and steep cut/fill slopes. Areas within the mapped project area (see Figure 2 and 3) are lacking in sage cover and bunch grasses required for sage -grouse production and forage. Some potential sage -grouse habitat occurs near the project area. Based on ERO's site review, sagebrush stands within and surrounding the Pond G project area are poor sage -grouse habitat for the following reasons, and are not anticipated to provide for sage -grouse life cycle needs: 1. Limited sage cover, with sage present belonging to a generally mature age class with relatively low recruitment; 2. Large interspaces and low cover of sage species; 3. Low percentage of bunch grasses in the understory; and 4. Hillsides are moderately to steeply sloped, and therefore do not provide optimal greater sage -grouse habitat. FRO Resources Corporatior. Page 4 Overall, the site contains relatively poor brood -rearing habitat for greater sage - grouse. The site was carefully reviewed, and no visible evidence — scat, secal dropping, tracks, or feathers — was observed during the site visit. General Wildlife A majority of the Pond G project envelope is disturbed or developed, and the facility is fenced to exclude wildlife. However, many wildlife species are known to occur in the area. Most are adapted to human -caused disturbances in the region. Species may include coyote, mice rats, raccoon, fox, various snakes, hawks, ground squirrels, and lizards. Oxy's wildlife policy states that Oxy employees and contractors will not harm or harass wildlife. A review of the NDIS map identified no sensitive ungulate habitat in the project area. Winter elk concentration areas occur about 0.5 mile south of the project area. No raptor nests or substrates were observed near the project vicinity at the time of the site visit. There also were no visual or auditory observations of raptors during the survey. Some aspen stingers are present though the trees are stunted and, based on past field observations, have low foliage cover during the growing season. The aspen stands likely do not provide suitable nesting raptor habitat and no raptors or nests were observed. Cliff habitat is present about 0.5 mile south of the project area. Migratory Birds Most birds in Colorado — with the exception of grouse and the non-native house sparrows, starlings, and rock pigeons — are protected by the MBTA. The regulatory definition of the MBTA prohibits, among other things, the act [or attempt] to pursue, hunt, shoot, wound, kill, trap, capture, or collect migratory birds, and applies to both live and dead birds as well as any part of their anatomy, nests, or eggs. However, the MBTA does not contain a prohibition that applies to the destruction of a migratory bird's habitat or the destruction of an inactive nest, as long as the nest or its contents are not collected. Nest destruction that results in the unpermitted take of migratory birds or their eggs is illegal and fully prosecutable under the rules of the MBTA (Migratory Bird Permit Memorandum, USFWS, April 15, 2003). The active nesting season for most migratory bird species in Colorado occurs between April 1 and August 31, which coincides with the peak construction season. Several state and federal agencies have adopted general species avoidance strategies, including vegetation removal outside of the breeding season, to preclude a violation of the MBTA. Impact Analysis The following sections evaluate the potential impacts from project implementation. The impacts can be completely mitigated; the approach to mitigate impacts is summarized in the "Recommendations" section that follows. Noxious Weeds No noxious weeds were observed during the site review; however, based on previous surveys, weeds likely are present. New activities, even if no new surface disturbance is proposed, can increase the distribution of noxious weeds via seeds trapped in equipment tires and crevices or personnel shoes and clothing. FRO Resources Corporatior. Page 5 Oxy monitors and treats noxious weeds seasonally, often beginning with bareground treatments in the early spring and spray applications as noxious weeds appear. Oxy tracks noxious weed treatment in compliance with Oxy's noxious weed management plan. TEPC Species No Threatened, Endangered, Proposed, Candidate, or other sensitive species occur in the project area. There are no anticipated impacts to this category of species. General Wildlife Temporary increases in human activity at the site may discourage use by some wildlife species; however, most species found in the project vicinity are acclimated to human presence and may temporarily alter their behavior patterns during active construction. The proposed project would not result in a permanent change in activity or any increase in the disturbance footprint; therefore no permanent impact to general wildlife habitat is anticipated. Oxy's wildlife policy states that Oxy employees and contractors will not harm or harass wildlife. Migratory Birds Clearing, grubbing, and increased human activity all have potential temporary and permanent impacts to migratory birds. No new surface disturbance is anticipated to result from proposed activities at Pond G; therefore no permanent impacts to migratory birds are anticipated. Increased human activity may temporarily discourage use of the project area by migratory birds; however this impact would be limited to the construction period. Following construction activities, birds are anticipated to resume their normal pattern of use and activity. Recommendations ERO recommends additional weed surveys and treatment be conducted prior to work at the site, in compliance with Oxy's Noxious Weed Management Plan. No new surface disturbing activities are proposed as part of the Pond G activities. If surface disturbance is required, ERO recommends the following step-down approach consistent with state and federal recommendations to avoid disturbing active bird nests during construction projects: 1. Conduct habitat -disturbing activities (tree removal, grading, scraping, grubbing, etc.) in the non -breeding season (September 1 to March 31) to the extent practicable. 2. If surface disturbing work activities are planned between April 1 and August 31, remove or alter vegetation within construction footprints and road right-of-ways (ROW) prior to April 1 to discourage nesting within areas scheduled for summer construction. Removal or alteration of vegetation will also discourage nesting in areas adjacent to the construction footprints and encourage birds to nest in more suitable habitat. Vegetation altering activities can include mowing or and/or trimming to a height of six (6) inches or less, grazing vegetation to a height of six (6) inches or less, disking, herbicide application, etc. FRO Resources Corporatior. Page 6 2a.Once vegetation has been removed and/or trimmed, appropriate measures, i.e. repeated mowing/trimming, should be implemented to assure vegetation does not grow more than six (6) inches. Note: Implementing these BMPs demonstrates a "Good Faith" effort to avoid incidental violation of the MBTA, but does not guarantee that migratory birds will not still nest in some areas despite these efforts. Additionally, depending on the elevation, weather, and species, the active nesting season may be earlier for species such as owls and raptors, or later at higher elevations. ERO recommends checking with a biologist to confirm the active nesting season in a particular location. No new surface disturbing activities are proposed as part of the Pond G activities. If surface disturbance is required, ERO recommends that all new temporary disturbance areas be reseeded with an appropriate seed mix, such as the mix shown in Table 3. Oxy will utilize the seeding mix identified in the SWMP. Table 3. Sample Montane Seed Mix.

The two fields operated by Oxy, the Cascade Creek Field and the Collbran Field, are both located within Garfield and Mesa Counties, Colorado, respectively. This operation includes +500 producing wells with associated production equipment and structures, several miles of natural gas and water gathering lines, satellite compressor stations and Targe compression facility. The office located in Grand Junction, Mesa County, Colorado serves as the support office for Piceance development. The business unit headquarters and additional support to Piceance operations is located in Houston, Texas. Most of the Oxy Piceance area operations in Garfield and/or Mesa County are located in rugged terrain, away from public access or direct influence. The enclosed maps show the general route of the field roads, well -site locations and major above -ground facilities. Natural gas is a safe, clean, dependable fuel used in millions of homes for cooking, heating, cooling and drying. It is also used by many commercial and industrial customers. Although typically safe to us, natural gas is an energy source and must be properly handled and does require a certain amount of caution when being produced and used. Natural gas is not poisonous; however, it does displace oxygen in enclosed spaces and may cause suffocation. In its pure state, natural gas is odorless. Odorants, in low concentrations, are added when the gas enters local distribution systems for safety purposes to serve as a warning of natural gas presence. DO NOT trust your sense of smell to identify a gas leak. The most effective method used by natural gas companies to locate leaks is with an instrument designed to "sniff" or locate leaks. A pipeline leak can be indicated by the following signs: (1) blowing sound; (2) dirt being blown into the air; (3) bubbles or water being blown into the air when the pipeline is located in a water source; (4) fire emanating from the ground or burning above the ground; (5) vegetation turning brown on or near the right-of-way; (6) persistent odor associated with natural gas. Natural gas is lighter than air and will not travel or accumulate close to the ground, as will liquefied petroleum gas (LPG) or gasoline fumes. It will rise quickly and be diluted in the atmosphere unless it is trapped within an enclosure. In order for natural gas to burn, it must be combined with air to a perfect mixture. When the gas is between 4 — 14% combined with air, it will readily ignite. Natural gas is compressible. It is compressed before entering transmission pipelines. Oxy Piceance area compressor and pipeline systems fully comply with state and federal standards for construction and operation. For production purposes, natural gas may also require the reduction and/or elimination of excess fluids and hydrocarbons. Separators and tri -ethylene glycol dehydration units are located at well locations and at the Conn Creek Compression Facility. The gas compression facility is not staffed 24 hours per day; however, emergency contacts are posted at the entry to the facility. Internal operations are monitored through electronic output with alerting capabilities 24 hours per day, 7 days per week. This facility is located on Oxy property. There are no residents within 1 mile of the facility. Public Safety Oxy Piceance area has operating procedures in place that are intended to protect the public and its employees from undue harm. In addition, the Company follows strict codes of compliance for the protection of public and Company property and the natural environment. When a concern for public safety is encountered within the Oxy Piceance area of operations, Oxy should be notified immediately! Oxy Piceance area employees and consultants are trained and equipped to handle unexpected conditions associated with the Company's natural gas production, gathering and processing systems. Emergency response organizations will be utilized where necessary and to assist with the public and neighboring properties during emergencies. Revised: 1 Aug 12 Oxy Piceance Area ERP Page 5 Emergency Response Plan (ERP) Components I. Pre -emergency Planning & Coordination With Outside Parties The following procedures cover emergency response guidelines that address anticipated emergency scenarios and define training required for employees engaged in oil or gas exploration and production (E&P) operations. The degree to which this ERP will be activated will depend entirely on the nature of the occurrence. There are (3) main options Oxy will decide when implementing the ERP, from most engaged to least engaged: offensive tactics, defensive tactics, and non-intervention. Remember, if offensive and defensive tactics are not feasible, there is always the option to non -intervene. The incident commander's option must account for life safety first, the environment second, and lastly, property (Oxy or non -Oxy). The Piceance ERP Manual will be reviewed and updated at least annually to reflect current activity and to increase effectiveness of the plan through discussions among all people involved. Each year Oxy employees are required to receive training on the ERP accompanied with real-life emergency drills, followed by a formal critique. These drills help improve the ER process, by addressing opportunities for improvement within the ERP system. This ERP has been shared with both Mesa and Garfield County officials, including the Local Emergency Response Commission (LEPC). The plan has also been distributed to the DeBeque Fire Department and the Plateau Valley Fire Department. II. Personnel Roles, Lines of Authority, Training, & Communication When feasible (dependent upon emergency severity) the Incident Command System (ICS) should be established consisting of a designated and trained incident commander, with assignments given to the four main categories for proper incident management: operations, logistics, planning, and finance. The incident commander will have the overall responsibility of determining what personnel best fits each needed function.

The purpose of this plan is to outline the responsibility for meeting such problems and to establish methods for handling the emergency with the least exposure to personnel, environment, and property. For the purpose of this plan, an emergency is considered to be any condition which requires assistance over and above that which can be supplied by the normal personnel present at the time or which cannot be handled in a routine manner. A first aid incident or minor fire which is limited to a small area, and which can be handled by the personnel present, does not fall under this plan. An emergency may include a medical emergency, fire, severe weather, explosion, uncontrolled release of natural gas or enemy action. Upon recognition of an emergency it is critical that the supervisor on location follow the appropriate incident notification outlined in Figure 1: Piceance Incident Notification Flowchart. Any lapse within the chain of Revised: 1 Aug 12 Oxy Piceance Area ERP Page 9 command locally, may severely damage the level of response needed, immediate crisis communication required to Oxy -Houston personnel, and Oxy's self-image and operating reputation within the community. Figure 2: Piceance Incident Notification Flowchart It is essential that all personnel are familiar with the location, operation and properly trained on fire extinguishers. Select personnel (i.e., plant operator) should be thoroughly familiar with all valves necessary to isolate the source of any natural gas leak, pipeline rupture, processing facility failure or other production related emergency. The location of all utility control points should be known by plant and field personnel, i.e., electric switch boxes, water and gas control valves. IV. Safe Distances & Places of Refuge Depending on the emergency, personnel shall evacuate to a location upwind and uphill, if possible. Personnel will meet at the designated safe area and a head count will be taken by the supervisor or the designee to ensure that everyone is accounted for. Each field area has specific pre -determined areas of refuge with a primary mustering point and a secondary mustering point (where applicable). It is important to note that each mustering point is identified with a mustering sign and a windsock (where applicable). Personnel should look for the mustering sign when evacuation is necessary. Below is a summary of the pre -determined mustering points for each field: (See the maps herein for aerial representation). Grand Junction Office: o Primary Mustering Point 4 Southeast corner of the parking lot o Secondary Mustering Point 4 Northeast corner of the parking lot Cascade Creek Field o Primary Mustering Point 4 Quadplex field office(s) o Secondary Mustering Point 4 Corral at Conn Creek Rd (GC Rd 213) & GC Rd 204 Collbran Field o East Plateau Area • Primary Mustering Point 4 East Plateau Field Office o Brush Creek Area • Primary Mustering Point 4 Brush Creek Field Office o Hell's Gulch Area • Primary Mustering Point 4 East of Compressor Station Site-specific evacuation routes, emergency procedures, and pre -selected muster points should be identified and confirmed at each pre -job and regularly scheduled safety meeting for daily work tasks. V. Site Security and Control The Operations Section, in conjunction with the incident commander shall be responsible for assigning company employees or contracted security forces to provide traffic control and establish a secure outside perimeter prior to being assisted by local emergency response personnel. Additionally, the hot, warm, and cold zones must be established for effective incident control. Figure 2 shows a generic incident layout. Revised: 1 Aug 12 Oxy Piceance Area ERP Page 10 Incident.

Evacuation Routes and Procedures The following are eight different potential emergencies that have been identified as having potential occurrence for Oxy's operations in the Piceance. It is imperative that employees familiarize themselves with each emergency procedure and varying evacuation route for each. The RED BOX is a quick tool to identify proper notifications, emergency tools, and forms that may need completion depending on emergency severity.

Revised: 1 Aug 12 Oxy Piceance Area ERP Page 31 VII. Decontamination Decontamination or DECON will be very limited to Oxy employees, due to the fact that offensive operations will be infrequent without the implementation of a respiratory protection program. However, it is the IC's responsibility to ensure that contract personnel involved with cleanup of hazardous materials follow proper DECON procedures. DECON shall always be established in the warm zone of an incident. VIII. Personal Protective Equipment (PPE) & Emergency Equipment PPE and emergency equipment is critical to an effective and safe emergency response for entry personnel. The Operations Section is responsible to ensure all entry team members are wearing the appropriate level of PPE. Currently, Oxy Piceance area have not implemented a respiratory protection program (RPP), since a program has not been deemed necessary for Oxy employees at this time. For this reason, PPE will strictly consist of an ANSI -approved hard hat and safety glasses w/ sideshields, ASTM -approved steel -toe boots or chemical resistant steel -toe boots, and 100% cotton/wool or FRC (flame resistant clothing). Additional PPE may include a Tyvek chemical splash suit, neoprene gloves, face -shield, goggles, etc., depending on the scenario. Of course, all emergencies shall require an appropriate PPE site analysis prior to entry. Emergency equipment is also critical to effective emergency response. Below is a general list of Oxy -provided equipment: (Note: this list may not be all inclusive) Emergency Equipment 1st Aid Kits 4 -Gas Monitor (CO, H2S, LEL, 02) Fire Extinguishers AED (automatic external defibrillator) (GJ office, CC Field office, CCCF Control room_) Backboard (located in CC Field Office) Explosion -Proof Flashlights Eyewash Stations & Bottles Spill Confinement Supplies (booms, diapers, pillows) (CCWHF, EPCS, Brush Creek office) Landing Zone LZ Turbo Lights (CC Field office, CCCF Control Room) St. Mary's Hospital Table 2: Emergency Equipment IX. Emergency Medical Treatment & First Aid In the event of an emergency involving injury to Oxy employees and/or contract personnel, immediate care shall be provided to the injured to abate any life-threatening injuries (e.g.; cardiac arrest, breathing stopped, and profuse bleeding, etc.), if deemed safe to do so. At least 50% of all Oxy employees are required to be trained in First Aid (FA), Cardiopulmonary Resuscitation (CPR), and the use of an Automatic External Defibrillator (AED). All other medical treatment beyond the first aid level, will require the evaluation of trained medical professionals from ambulance service to medical physicians at the clinic/hospital. The DeBeque Fire Department, the Plateau Valley Fire Department, and the St. Mary's Care Flight Helicopter can all provide advanced first aid at the Emergency Medical Technician (EMT) level. Hospital attention should be considered with respect to the below table, outlining medical facility protocol by priority. However, each emergency or incident should be managed case by case depending on injury severity. Priority Medical Facility Contact Number Non -Emergency Work Partners Occupational Clinic 970.241.5585 Non -Emergency Grand River Health & Safety Center 970.285.5731 Emergency St. Mary's Hospital 970.244.2990 Table 3: Medical Facility Protocol Revised: 1 Aug 12 Oxy Piceance Area ERP Page 32 X. Emergency Alerting and Response Procedure Once an employee recognizes the occurrence of an emergency, he/she will notify their immediate supervisor, following Figure 2: Incident Notification Flowchart. The on -scene Incident Command Staff shall notify the appropriate lines of authority and emergency response agencies as follows: A. Notify Mesa County Dispatch at 970.242.1234. B. Call law enforcement officers to help control traffic and the public, if necessary. If roadblocks are required and established during an emergency, advise the control points what outside help may be expected so that they can be admitted to the project area. C. Consider the necessity of evacuating any residents in the area. Currently, there are ranching interests and residential areas in the field(s) that may need notification. D. Establish contact with Civil Defense, Electric Companies, Gas Companies or other service organizations as needed. E. Contact Doctors, Hospitals, HAZMAT and ambulances as necessary. F. Contact any outside help necessary, such as construction contractors, tank trucks and other producers in the area which may be affected. G. Maintain communications and information flow with Oxy Piceance area and all potentially affected personnel. Notification to Oxy-MCBU management of any Health, Environment and Safety (HES) incident shall be made as soon as possible after the incident, so that additional steps can be taken as needed. Emergency response agencies as listed on page 3 of this plan shall be notified as needed. Below is the typical notification via the OXY chain of command, in accordance with OOG HES&S Procedure 60.400.0500 Incident Reporting and Investigation Standard.

Critique of Response & Follow-up Following all emergency response operations, a critique of the response efforts should be conducted to allow critical feedback that could improve the next potential emergency response management. This can be accomplished either verbally or in a structured, classroom setting outlining "what went right, what went wrong, and what can be improved on". The critique should always be documented for legality reasons. It is important to remember that a critique should be constructive, which means a positive effort is being conducted. An incident critique is not a "blame game". Additionally, all forms from each functional ICS group should be reviewed, for assistance with the critique. Any corrective actions developed from the critique should be documented and followed with action plans/target dates to ensure consistency with emergency response efforts throughout all operational phases. Revised: 1 Aug 12 Oxy Piceance Area ERP Page 34 Appendix A: Field Fire Prevention Plan Introduction The Fire Prevention Plan is a guide to help you know what to do and who to contact during a fire breakout in the mesa/valley where Oxy has operations. Having the available resources and knowing how to access them is crucial for someone who is involved in a fire incident and is injured or in critical condition. The information provided will help to increase an understanding of Oxy's policy and help in providing assistance to the general public and to Oxy should unexpected conditions arise which create a concern for public safety. All Oxy employees, contractors, sub -contractors, or anyone on Oxy -owned property should have the Emergency Response Plan (ERP) Manual available if needed for a resource in case of an emergency situation. The Fire Prevention Plan is in addition in the ERP Manual and specifically lays out a plan of action for workers to follow when an unexpected fire does happen. This section cannot cover all potential situations that may require emergency procedures. Check with the local Oxy representative for site specific procedures in effect for a particular work location. Types of Fires There are five general types of fires that have the possibility to occur on Oxy operations. They are lightning, smoking, flaring, hot work, and vehicle fires all which can result in a serious wild -land fire. Better understanding these types of hazards will only help you realize how to respond more efficiently if a wildfire occurs. Lightning Lightning is one of the most beautiful displays in nature. It is also one of the most deadly natural phenomena known to man. With bolts that are hotter than the sun, lightning can do some serious damage. One of the most common natural fires is caused by lightning. According to the Colorado Department of Local Affairs, "about half of all the wildfires in Colorado are lightning caused fires". Storms can move in very quickly on top of the mountain and lightning can become a severe hazard. In the United States alone, lightning sets 10,000 forest fires and causes $100 million in property damage every year. Always stay inside during a lightning storm; never go outside. If you are caught outside during a lightning storm avoid trees, fences, poles, or anything metal. Smoking The second type of fire is smoking. The best way to prevent a fire from smoking is to smoke only in designated smoking areas or in your vehicle. Never throw a cigarette butt outside. This is one of the most common ways fires are started. Pay attention to posted "NO SMOKING" signs and never smoke near flammable liquids or gases. Flaring Another potential fire hazard is flaring. Flaring or venting is a controlled burning process of natural gas that cannot be processed for sale or use because of technical reasons. Oxy has long used flaring and venting to Revised: 1 Aug 12 Oxy Piceance Area ERP Page 35 safely dispose of gases that occur in the production and processing of natural gas. In emergency situations, flaring provides a safe way to stabilize equipment. Hot Work A fourth fire danger is hot work which includes welding, grinding, and cutting. Each one of these is extremely dangerous because of the high fire danger they present. Dry, hot temperatures provide the perfect environment for sparks to ignite and start a wild -land fire. Every contractor who intends to perform one of these operations for Oxy must have a permit to do so before they start their job. Each contractor must have an established person that is the "fire watch" while the hot work is being performed. This person stands ready with an approved fire extinguisher to put out any fires that may start. The fire watch is required to remain at the hot work area for a period of 30 minutes after the job is complete. This lessens the chance of a fire occurring. Vehicle Hazards Another fire concern is vehicles that are equipped with catalytic converters. Catalysts reduce emissions by accelerating the combustion of pollutants leaving the engine. In doing this job, they get hot. The outside metal temperatures of some types of converters may approach 800 to 1000 F under conditions of extremely high engine loading. In other words, catalytic converters on vehicles get extremely hot after a long drive up the mountain. So parking should be only in a designated parking area at the location. Never park a catalyst - equipped vehicle, or any vehicle, on a pile of dry grass/brush or other dry vegetation. Always park where you can easily access the nearest exit by driving forward. Survey the scene so you know your exits for means of a quick escape. When a Fire Breaks Out: If a potential wildfire breaks out on the mesa, the most important thing is accountability. First of all notify someone of the fire, whether it be your supervisor, coworker, etc. Second, call the Mesa County Dispatch immediately at (970) 242-1234; the sooner the fire department is dispatched, the quicker the response time will be. All fires on federal lands should require immediate notification to the applicable Oxy personnel. Then analyze the situation and determine what the potential hazards are. Ask yourself these questions: Are there any hazardous or toxic chemicals at risk? Is the fire life threatening? Is there damage to public property? If possible and not a risk to life, isolate the fuel sources. Next, determine if the fire can be extinguished, if so, alert someone else of your plans, locate the nearest fire extinguisher and proceed to put the fire out. Every employee of Oxy should be trained on how to properly extinguish a fire. Note: Oxy recommends fighting a fire ONLY in the incipient stage. What is the incipient stage? A fire in its beginning stage. Incipient stage fires can be controlled with portable fire extinguishers. There are (4) steps to extinguish a fire called the PASS system: Pull - Pull the safety pin Aim - Remove the hose and aim the nozzle toward the fire Squeeze - Holding the handle, squeeze the trigger Sweep — Extinguish the fire in a sweeping motion, from left to right Revised: 1 Aug 12 Oxy Piceance Area ERP Page 36 When to Leave If the fire cannot be put out by the fire extinguisher in the incipient stage, it is time to evacuate the area immediately. Communication is key, inform everyone to evacuate the location and make sure everyone is accounted for. There should be designated meeting or muster points on location, where the entire crew/employees would meet in the event of an emergency. During the brief meeting, decide which route is the safest to use and evacuate as soon as possible. Cascade Creek There are (4) alternative routes of escape from Oxy Cascade Creek operations. The first three possible exits are drivable escape routes and the latter is a cow trail. The primary escape route is off the Oxy road leading to Conn Creek Road. The second is off Logan Wash Road if possible. The third alternative is to drive north on Trail Ridge Road, which is the road that lays directly north of the mesa well locations. If you stay on Trail Ridge Road it will eventually take you north to Rio Blanco County on County Road 5 and then to Colorado Highway 13. The other possible route would be to hike down the cow path that is connected to Oxy's valley operations. This allows (4) different evacuation routes where if one exit is blocked there is always an alternative. Please note the (3) secondary routes are ONLY for emergency access and are intended for the safe escape of Oxy contractors/sub-contractors. Collbran There are (3) alternative routes from the Oxy Collbran operations. All three are drivable escape routes on public highways. From the East Plateau area, one can take 60 Road, 59 '/2 Road, and Grove Creek Road North to Highway 330 and then head eastbound to Highway 65 to 1-70. A secondary escape route can be followed by heading South on 59 Road, to AA 50 Drive, to Lakeshore Drive, to Highway 65 southbound to Delta, then to the City of Cedaredge, to the City of Delta at Highway 92. The Brush Creek area primary escape route is Highway 330 eastbound to the City of Collbran and then eastbound to Highway 65, to 1-70. A secondary route can be followed westbound on Highway 330 to Northeast County Road 342, to North Divide Creek Road to the City of Silt and then 1-70. The Hell's Gulch area primary escape route is south on Canyon Road 342, to Highway 330 eastbound to the City of Collbran, and then eastbound to Highway 65, to 1-70. A secondary route can be followed westbound on Highway 330 to Northeast County Road 342, to North Divide Creek Road to the City of Silt and then 1-70. Where To Go Once you have evacuated the area, the primary muster point for each individual on the Cascade Creek lease would be the Oxy field offices. (Secondary is the cattle pens at Conn Creek Rd GC 213 & GC Rd 204.) Everyone should meet there and be accounted for by the supervisor in charge. If your path of escape is Trail Ridge Road, continue until you reach Piceance Creek, Rio Blanco county roads. Travel east on Rio Blanco County Road 5 to Colorado Highway 13 and then south on Highway 13 to Rifle, CO and Interstate 70. Revised: 1 Aug 12 Oxy Piceance Area ERP Page 37 Once you are in the safe zone contact your supervisor immediately for accountability. Drive careful and when emergency vehicles are met on the road, pull over and always give them the right away. Report all fires, regardless of the size to an Oxy representative as soon as possible. If a situation occurs where all exits are blocked, find a location with a bare, dirt pad and wait out the fire. Park your vehicle the farthest point away from all production units and methanol/condensate tanks and turn the engine off. Stay in your vehicle with the windows rolled up and the air conditioner/heater off, with all vents closed. This will keep smoke from entering the vehicle. Who/What is in Danger? There are several major operations that are in the danger zone if a fire breaks out. Drilling rigs, multiple production sites, various contractors on location, hunter/rancher cabins, and particularly temporary housing units are a major concern for Oxy. Also, other oil/gas companies in the area travel daily on Logan Wash Road and could also be affected. Temporary Housing Units One of the most susceptible places for a wild -land fire to catch employees off -guard is the temporary housing units. Remote locations provide an opportunity for a fire to easily arrive and trap employees with no access/egress to escape. The temporary housing units are being assessed per Colorado state and county regulations to ensure the health and safety of each employee. Fire Dangers/Hazards The following is a list of things that should be considered for fire prevention: • Temporary housing units must be a minimum of 75 feet from the well -head and condensate/methanol tanks. • Smoking is allowed only in designated smoking areas. Smoking is NOT ALLOWED inside any temporary housing units owned or leased by Oxy on Oxy property. Matches and all smoking equipment may not be carried into "No Smoking" areas. Butt disposal containers should be placed in the designated smoking areas. • Absolutely no drugs, alcohol, or firearms. Methamphetamine laboratories are EXTREMELY DANGEROUS and will not be tolerated on Oxy property. • All exits must be maintained free and clear of any obstructions. Exits must have free clearance of 10 feet. EXIT signs must be posted at each exit in the facility. Center to center between trailers must be maintained at a minimum of 20 feet. Exit stairs must be sturdy and level. • Areas around all temporary housing units shall be kept free of clutter. • All combustible waste materials must be disposed of daily. Bear -proof trash containers must be provided on the location. • No gas heaters are allowed on location. Only electric heaters or unit heaters are acceptable means of heating. • Absolutely no open -flame fires or charcoal grilling is allowed. Only gas cooking grills are allowable per Oxy approval, but must be 50 feet away from the well -head. • Vegetation must be cleared within a 10 foot distance around the facility. Revised: 1 Aug 12 Oxy Piceance Area ERP Page 38 • Fully charged and mounted fire extinguishers shall be available and accessible to all residents. They must be monthly and annually inspected and be located 75 feet (maximum) from any point in the facility. Access should be unobstructed and personnel trained to use the extinguisher. Extinguishers must be clearly marked. • Only non-flammable cleaning materials are allowed. • Flammable liquids shall not be stored within 50 feet of the well -head, unless otherwise approved. • All small gas/diesel containers must be stored at least 50 feet away from the temporary facility and the container must be an OSHA/NFPA approved safety can. • All electrical wiring and appliances shall be UL rated and shall meet all applicable federal, state and local building codes, OSHA standards and NFPA regulations. All units must be grounded. • Smoke alarms are required by NFPA Life Safety Code and will be inspected on a monthly basis. • Each site shall have a pre -determined muster point and all occupants of the temporary housing site shall be briefed on emergency action plans. How To Prepare for a Fire? Evacuation Drills/Training Every drilling rig crew, temporary housing occupants, and contractor that is staying on the mesa for a set time frame is required to have routine evacuation drills and training. Supervisors should provide information concerning the (4) evacuation routes, existing fire hazards, and important safety concerns on a weekly basis. Employees need to know the Fire Prevention Plan, so when the unexpected does happen, they will be ready. The Emergency Response Plan (ERP) Manual and Fire Prevention Plan is available upon request to each critical contractor/employee before employment, with the expectation that the critical contractors/employees will brief individuals and visitors they oversee. The fire hazards will be discussed and any questions or concerns should be brought to attention immediately. It is important to know the potential hazards that exist during a job and the resources that your safety depends on. Fire Prevention Checklist To ensure that you know this fire plan, ask yourself these questions: ✓ What fire hazards exist around me? ✓ What are the (4) evacuation routes that are available? ✓ What is the best exit for a means of escape? ✓ Who do I call in case of a fire? ✓ Where do I access emergency contact information? ✓ Is the fire life threatening? ✓ Where is the closest fire extinguisher? ✓ Where is the muster points in case of an emergency? ✓ What is the weather like, windy, thunderstorms, etc.?

Touchdown Area: The touchdown area should be square with a minimum of MO feet on each side. The landing site should be clear of people, vehicles, and obstructions such as trees, poles, and wires. Keep in. mind that wires cannot be seen from the air at night. The landing site must be free of stumps, brush, posts, and Targe rocks. Wind Direction & Touchdown Area Consider the wind direction. Helicopters land and take off into the wind. Inform the pilot of the direction from which the wincl is blowing. i.e. "Wind from the era>rtb.' Is the approach and departure path free of obstructions (wires, poles, antennas, trees, etc.)? If there arc obstructions, please tell the CareFlight team during the initial radio call. Illumination of the LZ at Night Mark the touchdown area with five lights/road flares (one in each corner and one indicating wind direction). When using automobile(~), place the vehicle(s) in position based upon the number of vehicles available. For instance, if only one vehicle is available, place it in vehicle #1 position (pointing into the wind). If two vehicles are available, place them In vehicle #1 and ?r2 positions, etc. Ilse any additional vehicles (if more than 3 available) to illuminate flight and land- ing surface obstacles. At night, assure that spotlights, floodlights, vehicle lights, and handlights used to define the I2. and obstacles are not pointed toward tlic helicopter.lurn off non-essential Iights.White lights, such as spotlights, flash bulbs, and headlights ruin the pilot's night vision and temporarily blind him. Red lights or blue lights, however, are very helpful in finding accident locations and do not have a detrimental effect on the pilot's night vision. Select a landing site clear of trees, pales and wires. Keep approach/departure path free of obstructions. When using automobiles to illuminate the nighttime landing zone, place in the positions as shown above. 11 Revised: 1 Aug 12 Oxy Piceance Area ERP Page 40 LISt. Mary's j CareFlight Personnel Safety Keep spectators at least 20() feet from the touchdown area. Keep emergency service personnel at least 100 feet away, if possible. Encourage everyone working near the helicopter to wear eye protection. Remove hats or helmets or fasten chin straps (no loose hats blowing up through rhe rotors)? Reties of Thumb for Safe Distances: • 100 feet from helicopter to waiting ambulance • 200 feet from helicopter to crowds & pedestrians • 300 feet from the helicopter to stopped traffic • 200-400 feet from accident victims to traffic Ground Guide: When CareFlight arrives at the scene, only one person should give 12, wind, and obstacle instructions. 'Ibat person should wear eye protection and they should stand with their hack to the wind and arms raised over head to indicate the direction of the wind, which will usually be the opposite of the landing direction. As the helicopter turns into the wind, and begins the final descent, the ground guide should leave to a safer area, Communications One person, the 1,Z coordinator, will be responsible for all communication with the pilot.The 12 coordinator should monitor the radio at all tithes when the helicopter is running. It is CareFlight's policy 0) monitor the 12 frequency for at least two minutes after departure_ Every attempt will he made to contact the 12 coordinator on the frequency specified in the dispatch call. In the event that communication cannot be established on that frequency, the helicopter will monitor NLEC (National Law Enforcement Channel). Please immediately report to the pilot any observed hazards and wait for his acknowledgement. TOUCH DOWN AREA WIND D!

General He[itopter Safety Rules • The pilot will perform as many high reconnaissance whit as they feel necessary to insure a safe landing. • When working around any helicopter, never approach from the rear.A1ways approach and depart the aircraft towards the front so you can see the pilot and so he ran see you, The I.7, coordinator will designate as many persons as neces- sary for crowd control. • If the helicopter is landed on a slope approach and depart .from the down-slope side, unless that is the rear of the heli- copter -An that circumstance, approach from the left or right from the most level ground and in plain Sight of the pilot. • "When the helicopter is loaded and ready for take -off, keep the departure path free of vehicles and spectators or rescue personnel. If an emergency were to occur during take -off, we would need this area to execute our landing. Assistinl� the CareFlight team Once CareFlight has landed, only briefed emergency person- nel should approach the helicopter. Be sure to receive a"go- ahead" sign from the pilot before stepping under the rotor tip path and then approach from the front of the helicopter h landing zone coordinator should be prepared to assist the crew by providing security for the helicopter The tail rotor is the most dangerous area -if asked to provide security, do not allow anyone but the crew to approach the helicopter. Note: 'Fite Bell 412 loads from the left or right side, feet first.

The preparations far helicopters responding 0) these accidents also require spe- cial considerations. Helicopter medical craws normally do not carry protective snits or breathing apparatuses to protect them from hazardous materials. Upon initial radio contact, the CareFlight team must he made aware of any hazardous materials or gases in the area. If the aircraft were to fly through the hazardous gases, the crew could he poisoned and the engines could develop mechanical problems, or cause an explosion or fire, Never assume that the crew has already been informed of the 1-I oijnat situation. Hazardous materials of concerts are toxic, poisonous, flamma- ble, explosive, irritating, or radioactive in nature. Patients exposed to hazardous materials will require decontamination prior to air transport to avoid contamination of the crew and aircraft. Some radioactive materials are more dangerous than others, depending upon the type and amounts of those materials. In general, radioactive materials are difficult to ignite, but will born, and the smoke is toxic. The CareFlight team should he advised if victims niay be con- taminated by radioactivity. Hazardous Materials LZ Preparation and Considerations Ile[lcopter landing zones muse he selected to avoid possibility of compromising the safety of the CareFlight team and adja- cent people and property, When explosives, poisonous gases/vapors, or chemicals in danger of exploding and burning are on site, helicopter landing t zones must be prepared upwind, a safe distance (may he as much as one mile) from the hazardous material accident site, and never in low-lying areas.Tlte toxic gases or vapors may be heavier than air ala[ gather in these low-lying areas. For hazardous material accidents involving radioactive materi- als, the CareFlight 12 must be prepared upwind, a safe distance (mar be 1/4 mile) from accident, unless there are radioactive gases (steam or smoke), and in this case, the LI, must he at lease one mile upwind of the accident site. CareFlight must be notrfied of .hazardous materials on the scene in order to ovoid contamination of the flight tech -17 and aircraft.
