Per the Garfield County Unified Land Use Resolution, Oxy is requesting a Limited Impact Review (LIR) 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 nontributary water source within the Williams Fork Formation. The Ponds are located in the NE 1/4 of the SE 1/4 and the SE 1/4 of the SE 1/4 of Section 4, Township 6 South, Range 97 West, of the 6th Principal Meridian, in unincorporated Garfield County, Colorado. The proposed Facility will allow for effective reuse 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 reuse 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 sent off site • Conservation of freshwater 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 13 E/W Centralized E&P Waste Management Facility • Reduced road maintenance • Reduction in overall development and operating cost Details of this request along with the information required by Garfield County's (GarCo) LIR application are provided within the context of this submittal. Since this application is to convert an existing production pond into a Centralized E&P Waste Management Facility, no proposed Facility structures, access roads, or surface water diversion structures will be required. The Facility has been constructed to contain 121,480 barrels of produced water which does not include the required two feet of freeboard, 68,010 barrels for Pond 13 East and 53,470 barrels for Pond 13 West. The Facility utilizes a 60 -mil high-density polyethylene (HDPE) liner and a geocomposite base liner to provide sufficient bedding material for the liner. Once the Facility is approved by the COGCC for conversion, Oxy will install a leak detection system and a second 60 -mil HDPE liner. The leak detection system will allow for fluid monitoring between the two HDPE liners at the Facility. In addition to the water impoundment, storage areas as depicted on the site plan are being requested. The proposed storage area will be utilized to store equipment and supplies on-site for convenient access as needed for Oxy's natural gas drilling and production activities. Hazardous materials will not be stored at this location. The proposed use will not require additional surface disturbance. Oxy employees and contractors will be on-site for short intervals picking up or dropping off supplies. Sanitation facilities and office space have not been proposed. Portable toilets are provided throughout the area for use by field employees.

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, Suite 102 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 currentiy 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 Ran: Not applicable. 22. Additional Information: None. 23. Signature Block: See below.

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 3.25 acre. (141,570 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 13 LOCATION: Garfield County, CO DATE: 8/13/13 Item Description (Source of Cost) Garfield County Vegetation Management Cost/ Acre $2,500 Total Acres 3.3 Estimated Total Cost $8,250 (costs have been provided by Garfield County Vegetation Management) 2 Drainage and Erosion Control Plan The primary disturbance anticipated with the closure Pond 13 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 CA04 and 0S18 drainage basins 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 (Dactylis 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. (Al 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. Attachment E Cascade Creek Stormwater Permit COR0038414 STATE OF COLORADO John W.

The project area is also located above Cascade Canyon and the Conn Creek drainage in Section 4, Township 6 South, Range 97 West of the 6th P.M. The site has been disturbed and contains two fenced and lined production water ponds. Prior to being disturbed, the site contained a mix of scrub -shrub upland habitat dominated by sagebrush and Gambel oak with aspen occurring along the adjacent drainages and higher elevations. 5. Soil Characteristics The soil at this location consists of 55 — Parachute — Irigul complex, 5 to 30 percent slopes and 56 -Parachute — Irigul-Rhone association, 25 to 50 percent slopes. 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 Pond 13 E/W Centralized E&P Waste Management Facility 6. Geology and Hazard Topography The Oxy Pond 13 Water Storage 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 water storage 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 8,600 feet above mean sea level. The elevation of Cascade Creek lies at approximately 8,200 feet or 400 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 — Irigul complex, which is 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 60 percent Parachute soil and 30 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 Irigul soil is shallow and well drained and is formed in residuum 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 7 inches thick, and siltstone is encountered at a depth of about 13 inches. Permeability is moderate and the available water capacity is very low. 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 siltstone and mudstone, becoming more coarse-grained and permeable toward the top of Impact Analysis Page 2 OXY Pond 13 E/W Centralized E&P Waste Management Facility 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 Structures The water storage facility is located on the northeastern limb of the Crystal Creek Anticline. 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). 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 Impact Analysis Page 3 OXY Pond 13 E/W Centralized E&P Waste Management Facility 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 waste management 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 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. Impact Analysis Page 4 OXY Pond 13 E/W Centralized E&P Waste Management Facility Surface Water Features Surface water features within two miles of the project site include Cascade Canyon located approximately 1,640 feet to the southwest of the water treatment facility, and Little Creek approximately 1,624 feet to the northeast. The site lies on a drainage divide between Cascade Creek to the southwest and Little Creek to the northeast. If a produced water spill were to occur and leave the site, it is expected that it would flow toward Cascade Canyon. Oxy USA WTP had another permitted pit named the MCM #83-92 Pit (COGCC facility ID #273647) located approximately 1,130 feet to the north. The MCM #83-92 pit is shown as being closed on the COGCC GIS database. 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 4, Township 6 South, Range 97 West. However, there are springs shown in adjoining Section 3, Section 5, Section 9 Section 10, Township 6 South Range 97W, and in Section 36, Township 5 South, Range 97 West, of the 6th Principal Meridian. These springs are all located at elevations of less than 8,400 feet and most are closer to an elevation of 8,200 feet above mean sea level. Shallow Groundwater and Major 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 8,600 feet. Cascade Canyon is the nearest surface water and lies at elevations of 8,200 feet to 8,400 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 4, Township 6 South, Range 97 West. There are no permitted water wells in close proximity to the site. The nearest permitted water wells are shown in Section 5, Township 6 South, Range 97 West, and are located across the Conn Creek drainage from the proposed site. These wells are identified as belonging to Williams Production RMT, Cliffs Engineering, and Cities Service Oil and Gas Corp. Some of these wells appear to have been abandoned, and others appear to be used as monitoring wells. They are all located at an elevation of approximately 8,400 feet above mean sea level. 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 Impact Analysis Page 5 OXY Pond 13 E/W Centralized E&P Waste Management Facility 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 — Animas 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 Tong -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 Pond 13 E/W Centralized E&P Waste Management Facility OXY commissioned ERO Resources Corporation (ERO) to prepare a biological resources survey of the site and that report is included as an attachment to this application. According to ERO, the site has the potential for one federally threatened, proposed and candidate species to occur near 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 was no raptor nests observed near the project area. 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 dust suppression during construction and operation of the facility. Any lighting on-site will be downcast. Impact Analysis Page 7 OXY Pond 13 E/W Centralized E&P Waste Management Facility 10. Hours of Operation The Pond 13 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 either recycled for well completions or eventually disposed of at a permitted facility. The facility is currently constructed as a production pond facility and is requesting approval as a Centralized E & P Waste Management facility. It is expected that the lifespan of the site will be approximately 30 years. The site is located approximately 23 travel miles north of the DeBeque interchange (MP 61.6) along Interstate 70 (1-70) at DeBeque. The facility is located in the Northeast 1/4 of the Southeast 1/4 of Section 4, Township 6 South, Range 97 West of the 6th Principal Meridian in unincorporated Garfield County. The subject site is located on a 640 acre parcel. The property is owned by and the facility is operated by Oxy. Oxy is in the process of permitting a number of facilities located in the general area. All of these facilities will individually generate low volumes of traffic. Two facilities are for storage and will reduce the current practice of hauling materials and equipment to and from the top of the plateau. Two facilities are for the storage and management of produced water and will allow for water recycling in the field and reduce the need for trucks to haul water for final disposal. The objective of this analysis is to review the existing road network, provide traffic projections and trip assignment for the facility, and assess the need for access permitting. EXISTING ROAD NETWORK Regional trips to this facility will use 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 until the road 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. These private roads are located on property owned by Oxy. The facility is located an additional 11 miles up Cascade Creek and on the top of the Roan Plateau. There are no County or public roads within a 1 -mile radius of the facility. Oxy Pond 13 E/W 1 August, 2013 Basic Traffic Analysis 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 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 county -wide traffic study where daily traffic was counted for county roads. The study concluded that the average daily traffic (ADT) was 337 vehicles per day (vpd) on this road 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. The 2002 Garfield County Road & Bridge conducted county -wide traffic study showed the CR 213 ADT to be 9 vpd for this road. There is a right -turn lane for northbound traffic on CR 204 turning right onto CR 213. The intersection is stop controlled with CR 213 as the minor leg. TRAFFIC PROJECTIONS Background traffic volumes were increased to present day values for comparison purposes. Given the lack of data regarding traffic growth for this area, a growth rate of 3% is assumed. This rate was applied to the existing counts to obtain background traffic for the year 2013. This results in an estimated ADT of 446 in 2013 for CR 204. The result for CR 213 in 2013 is an estimated ADT of 12 (Table 1). Table 1: Background Traffic Proiections — Pond 13 E/W Facility Oxy Pond 13 E/W Basic Traffic Analysis 2 August, 2013 2002 Actual 2013 Estimated CR 204 337 446 CR 213 9 12 Oxy Pond 13 E/W Basic Traffic Analysis 2 August, 2013 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 two (2) days. 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 one to two (1-2) transport trucks per day and one (1) additional pickup truck and one 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 13 E/W Facility Phase Average Trips/Day Maximum Trips/Day Percent Trucks Average Total Trips/Phase Phase Duration Operation 2 4 33 % 21,900 30 years Drilling & Completions 5 7 39% N/A N/A Combined 7 11 33% N/A N/A County Road 204 Based on the County's background traffic calculations, Oxy's Pond 13 E/W facility related traffic will have an average of <1% increase on daily traffic activity during operations of the facility in 2013 on CR 204. Traffic activities will increase from the 2013 estimate an average 2.45% during drilling and completion operations on CR204. 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 ponds are 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 Oxy Pond 13 E/W 4 August, 2013 Basic Traffic Analysis 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 intersects 1-70 at Exit 62 in 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. The US Highway 6 / 1-70 Frontage Road terminates at Mesa County 45 Road approximately 300 feet northwest of the DeBeque interchange. This intersection is two-way stop -controlled. Traffic traveling to this site from 1-70 would have the right-of-way at this intersection. Railroad Crossings Mesa County 45 Road crosses under a main railroad line approximately 0.5 miles north of 1-70. This line is generally used for the transport of freight, coal, and passenger rail traffic. This railroad crossing is grade separated. Clearance for transport trucks under this railroad bridge is adequate. The roadway access to this site does not cross any other active railroad right-of- ways. 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 Oxy Pond 13 E/W 5 August, 2013 Basic Traffic Analysis is associated with the natural gas industry. At worst, there would be a minor increase in traffic which would peak during drilling and completion activities. As mentioned in the Roadway Analysis, the addition of traffic generated by the proposed facility does not increase existing volumes to levels required for State or County permits.

Water Supply and Distribution Plan. The Oxy Pond 13 facility does not require potable water source for personnel or freshwater for sanitary facilities, landscaping or day to day operations of the facility. The operations of the facility will be similar to other natural gas operations in relatively remote areas of Garfield County. No potable water will be provided at this facility. The proposed use is an unmanned facility with personnel onsite only for short intervals. Personnel provide their own potable water carried in their vehicles. Oxy makes potable water available at their field office to staff and contractors. Sanitary facilities will not require a source of water and will be provided by portable toilets located at numerous sites in the field per OSHA standards. Landscaping is not being proposed and a water system is not required to maintain any plantings. The storage facility does not use water in its daily operation.

The short title of these rules and regulations is "Produced Nontributary Ground Water Rules" and in this document the rules and regulations may be referred to as "Rules," 17.2 Authority These Rules are promulgated pursuant to the authority granted the State Engineer in House Bill 09-1303, Section 3, as codified at section 37-90-137(7)(c), C.R.S.; and section 37-80-102(1)(g), C.R.S. 17.3 Scope and Purpose of Rules A. The purpose of these Rules is to assist the State Engineer with administration in the case of dewatering of geologic formations by withdrawing nontributary ground water to facilitate or permit the mining of minerals. B. These Rules establish procedures pursuant to which an operator may petition the State Engineer for a determination that water that is being or that may be withdrawn from geologic formations to facilitate or permit the mining of minerals is nontributary, as defined at section 37-90-103(10.5), C.R.S. These Rules further identify certain areas, locations and formations within the State of Colorado where the State Engineer shall regard ground water removed from geologic formations to facilitate or permit mining of minerals to be nontributary. C. These Rules provide for the use of engineering and scientific methodologies, including the use and results of ground water modeling or other ground water characteristics, such as water chemistry, hydrogeology, or other scientifically based approaches, that an applicant may rely upon in support of a petition for a nontributary determination. D. These Rules apply only to ground water removed from geologic formations to facilitate or permit mining of minerals. Consistent with section 37-90-137(7)(c), C.R.S., the State Engineer is adopting these Rules to assist with his administration of ground water withdrawn to facilitate or permit the mining of minerals. Consistent with the intent of House Bill 09-1303, such administration includes the State Engineer using nontributary Produced Nontributary Ground Water Rules 2 CCR 402-17 1 determinations made pursuant to these Rules for purposes of issuing water well permits pursuant to section 37-90-137(7), C.R.S., and to obviate the need for administration of wells subject to permitting consideration, as allowed by sections 37-90-137(7) and 37- 92-305(11), C.R.S.. The State Engineer shall not use these Rules for permitting of wells pursuant to section 37-90-137(4), C.R.S. E. These Rules do not apply to any aquifer or portion thereof that contains designated ground water and is located within the boundaries of a designated ground water basin. F These Rules and regulations shall not be construed to establish the jurisdiction of either the State of Colorado or the Southern Ute Indian Tribe over nontributary ground water within the boundaries of the Southern Lite Indian Reservation as recognized in Pub.

Produced Nontributary Ground Water Rules 2 CCR 402-17 2 17.5 Process for Obtaining a Determination of Nontributary Ground Water Any person may seek to amend these Rules, through applicable rulemaking procedures, to identify areas within the State of Colorado where the State Engineer shall regard Produced Water to be nontributary, or to amend, based on factual information not presented at the time of adoption, the Rules to exclude areas previously determined to be nontributary pursuant to these Rules or any amendment thereof. An amendment excluding areas previously determined to be nontributary will not invalidate any existing permits issued pursuant to these Rules or otherwise cause the State Engineer to change his administration of wells in existence prior to such amendment. As an alternative to requesting a rulemaking proceeding, an Operator may obtain a determination regarding the nontributary nature of Produced Water through an adjudicatory proceeding before the State Engineer. Any such request for a nontributary determination must be submitted pursuant to the procedures set forth in this Rule 17.5. These Rules do not preclude any Operator from obtaining a determination regarding the nontributary nature of Produced Water, for the purpose of section 37-90-137(7), C.R.S., through an appropriate proceeding before the Water Court. A. Submittal of Petition for a Determination of Nontributary Ground Water An Operator or group of Operators seeking a nontributary determination for Produced Water withdrawn from an existing well or group of wells, or for a well or welts to be constructed in one or more geologic formations within a geographically delineated area ("Applicant") shall file a petition in the form of a letter and accompanying professional report to the State Engineer. The petition shall at a minimum contain the following information: 1. Information indicating whether the ground water will be withdrawn to facilitate or permit the mining of minerals, or withdrawn for purposes other than the mining of minerals. 2. Information indicating whether the Applicant is seeking a nontributary determination for a single well, group of wells, or for all wells, whether such wells have been constructed or are proposed to be constructed in one or more geologic formations within a geographically delineated area. 3. Information sufficient to demonstrate, through analytic or numeric modeling, that the depletions that result from pumping at the location of the well, wells, or at any well constructed, or proposed to be constructed in one or more geologic formations within a geographically delineated area, meet the nontributary standard. In lieu of ground water modeling, the Applicant may provide geologic, hydrologic, and other information sufficient to demonstrate that each subject geologic formation at the well location or within the geographically delineated area is hydraulically disconnected from all surface streams such that there will be no depletions to any surface stream as a result of pumping. B. Notice and Comment 1. Concurrent with submission of the petition to the State Engineer, the Applicant shall file notice of the petition. The notice shall be sent to all parties on the Produced Nontributary Ground Water Notification List for the water division in Produced Nontributary Ground Water Rules 2 CCR 402-17 3 which the subject ground water is located and the primary newspapers in circulation in the affected watersheds. 2. The State Engineer shall establish a Produced Nontributary Ground Water Notification List for each water division within the State of Colorado for the purposes of ensuring that water users within each water division receive adequate notice of proceedings held pursuant to these Rules. In order to establish such notification list, the State Engineer shall, immediately upon effect of these Rules, and in January of each year thereafter, cause to have published in the water court resume for each water division an invitation to be included on such notification list for the applicable water division. Persons on the Produced Nontributary Ground Water Notification List shall be provided notice required pursuant to these Rules by either first-class mail, or, if a person so elects, by electronic mail. 3. The State Engineer shall allow 30 days for any person to respond to the petition. A person may respond to the petition by submitting written comments or by requesting that the matter be referred for hearing on the petition. The person must state the basis for such a request in sufficient detail to allow the State Engineer to determine whether a hearing is appropriate prior to an Initial Determination. The Applicant or the staff of the State Engineer may also refer the matter for hearing on the petition. If the State Engineer determines a hearing is appropriate, he shall schedule a hearing pursuant to the procedures described below. The State Engineer may submit the matter to a designated Hearing Officer at his discretion. C. Initial Determination 1. If no person requests a hearing, the staff of the State Engineer shall evaluate the petition and any written comments, and produce an Initial Determination with respect to whether water withdrawn from an existing well or wells proposed to be constructed in one or more geologic formations within a geographically delineated area is nontributary. The Initial Determination may find that water from only certain wells or certain locations is nontributary. 2. The staff of the State Engineer shall provide a copy of its Initial Determination to the Applicant, any person who submitted written comments, and any person who requested a copy of the Initial Determination. If no person objects to the Initial Determination within 30 days, the staff of the State Engineer will submit its initial determination to the State Engineer for review and certification as a Final Decision, as described below. D. Hearing 1. If any person objects to the Initial Determination, or if the State Engineer has determined a hearing is appropriate before an Initial Determination, the matter will be set for an adjudicatory hearing before the State Engineer. The person objecting must state in detail the basis for such an objection to the Initial Determination. Produced Nontributary Ground Water Rules 2 CCR 402-17 4 2. The hearing shall be conducted pursuant to the Division of Water Resources Procedural Regulations, 2 CCR 402-5, and applicable provisions of the State Administrative Procedure Act. The Applicant shall provide notice of the hearing to any person who responded to the petition. 3. For purposes of the hearing, the Applicant shall be considered the party requesting the hearing and the proponent of the order, and shall have the initial burden of proof. Any person who responded to the petition may participate as a party to the hearing. The staff of the State Engineer may participate as a party. 4. The State Engineer may consider the Initial Determination of the staff of the State Engineer as evidence; however, the hearing will be de novo, based upon the evidence presented at the hearing. E. Final Decision If no hearing is held, the Initial Determination shall become the Final Decision of the State Engineer ("Final Decision") with respect to the Applicant's petition. If there has been a hearing on the petition, the decision of the State Engineer shall become the Final Decision of the State Engineer pursuant to procedures set forth in the Division of Water Resources Procedural Regulations, 2 CCR 402-5, and applicable provisions of the State Administrative Procedure Act. F. Effect of Final Decision 1. The State Engineer shall rely upon the Final Decision to evaluate well permit applications submitted pursuant to section 37-90-137(7), C.R.S., where an operator is withdrawing nontributary ground water to facilitate the mining of minerals, and where the nontributary ground water being removed will be beneficially used. 2. The State Engineer shall rely upon the Final Decision to authorize the withdrawal of nontributary ground water to facilitate the mining of minerals without requiring a well permit, pursuant to section 37-90-137(7), C.R.S., where the nontributary ground water being removed will not be beneficially used. 3. Where a Final Decision is applicable to all wells to be constructed within a geographically delineated area, the State Engineer shall rely upon the Final Decision to evaluate all wells constructed within that area for the purposes set forth in the preceding paragraphs. 17.6 Engineering and Scientific Methodologies and Standards A. An Applicant shall comply with the engineering and scientific methodologies and standards described in Rule 17.6 of these Rules when submitting a petition for determination of nontributary groundwater made pursuant to Rule 17.5 of these Rules. B. Conceptual Model For any petition for determination of nontributary groundwater submitted pursuant to Rule 17.5 of these Rules, an Applicant shall include a conceptual model of the geologic Produced Nontributary Ground Water Rules 2 CCR 402-17 5 and hydrogeologic characteristics of the relevant area, formation or basin under consideration. The conceptual model shall adequately represent the known geologic and hydrogeologic characteristics of the ground water system. At a minimum, the conceptual model shall define the hydrostratigraphic units along with any known characteristics and boundary conditions. The conceptual model will determine whether numerical or analytical modeling, or alternative methodologies are appropriate for evaluating the petition for a determination of nontributary ground water. For numerical modeling, the conceptual model shall establish the preliminary water budget of the system, which should include sources of water, flow directions, and discharge or exit points. C. Ground Water Modeling 1. An Applicant may use mathematical ground water modeling simulating the ground water system through equations that describe the heads or flows with representative boundary conditions to demonstrate that the withdrawal of produced ground water that is, or is presumed to be, in hydraulic connection with the surface water system is nontributary, as defined at section 37-90-103(10.5), C.R.S. 2. Any ground water model used to demonstrate that the withdrawal of produced ground water that is, or is presumed to be, in hydraulic connection with the surface water system is nontributary shall comply with the protocol for development and use of a mathematical ground water model as generally agreed upon by technical experts in the water resources discipline. Many analytical and numerical models are available that may be found acceptable for use in the evaluation of an Application. However, the Applicant must demonstrate the model's suitability and applicability to determining that the ground water is nontributary. The Applicant should contact the State Engineer's Office regarding the use of models since certain models will have more or Tess credibility with ground water modeling experts. 3. For situations in which the hydrologic system is under confined or semi -confined conditions, model calculations shall utilize a storativity (storage coefficient). A specific yield value may be used in the calculations where water table (unconfined) conditions exist. 4. All data files used in a numerical or analytical ground water model shall be provided in an electronic format deemed acceptable to the State Engineer's Office. All data files shall include the model input files as well as any supporting data used in the development of the model input files. Any GIS shape files used in the development of the model shall also accompany submittal of the model. 5. Documentation to explain the context and methodology of all ground water modeling shall accompany the Professional Report as described in Rule 17.6.E. It is incumbent upon the Applicant to demonstrate to the satisfaction of the State Engineer's Office that the model code and input data are suitable and applicable for determining that the produced ground water is nontributary. Proprietary information and data need not be disclosed by an Applicant beyond that which is Produced Nontributary Ground Water Rules 2 CCR 402-17 6 deemed necessary by the State Engineer's Office to evaluate the model and verify model input parameters. 6. Any party objecting to a petition for an adjudicatory proceeding or objecting to an Initial Determination, as specified in Rule 17.5, may obtain all supporting information relied upon by an Applicant in developing any ground water modeling, or alternative methodologies. The Applicant's obligation to disclose such information arises upon request of any party and, to the extent that the Applicant deems and the State Engineer finds any such information sensitive, confidential, or proprietary, the parties and State Engineer shall agree to hold such information confidential and protect it from public dissemination under appropriate terms and conditions. D. Alternative Methodology 1. Geologic conditions at a site may effectively isolate the mineral -bearing production zones from the surface water system. An alternative method may be utilized to demonstrate that ground water produced in conjunction with the mining of minerals from the potential and existing production zones is nontributary. Alternative methodologies are intended to demonstrate that the production zones are disconnected from the surface water system by a lithologic discontinuity or structural separation between the production zone and its outcrop equivalent. 2. The criteria for demonstrating isolation of an existing or potential production zone from the surface water system may include both direct and indirect physical evidence such as that obtained from drilling, borehole geophysical logging, surface seismic and geophysical surveys, drill stem and pump tests, geochemical analyses and surface and subsurface mapping. Geologic and geophysical maps and cross sections shall be based on actual evidence obtained from drilling, geophysical and/or seismic surveys or other verifiable geotechnical investigations. Location, seismic and geophysical survey data, including GIS data, shall be submitted in a paper and/or electronic format deemed acceptable by the State Engineer's Office. 3. Published professional reports, investigations, or technical papers may be provided as a source of factual evidence in support of a petition. 4. Petrophysics, hydrogeologic data and water chemistry may be used to support the conclusions of a petition. Samples of water and gas, or other media to be subjected to chemical or isotopic analysis, shall be collected, handled and analyzed to ensure that the results are consistent with the intended use of the data. A detailed description of the sample collection procedures and analytical methods shall be submitted to the State Engineer's Office upon request. Laboratory data shall be submitted in a format deemed acceptable by the State Engineer's Office. 5. Copies of supporting evidence shall be provided to the State Engineer's Office upon request. Such evidence may include, but is not limited to, geophysical logs and surveys, pump and drill stem test data, lithologic descriptions or other Produced Nontributary Ground Water Rules 2 CCR 402-17 7 physical or hydrologic analyses and water quality/chemistry analyses on which the Applicant has relied to support a petition. Proprietary information and data need not be disclosed by an applicant beyond that which is deemed necessary by the State Engineer's Office to evaluate the petition and demonstrate that the data on which the Applicant's conclusions are based is valid. 6. Any party objecting to a petition for an adjudicatory proceeding or objecting to an Initial Determination, as specified in Rule 17,5, may obtain all supporting information relied upon by an Applicant in developing any ground water modeling, or alternative methodologies. The Applicant's obligation to disclose such information arises upon request of any party and, to the extent that the Applicant deems and the State Engineer finds any such information sensitive, confidential, or proprietary, the parties and State Engineer shall agree to hold such information confidential and protect it from public dissemination under appropriate terms and conditions. E. Professional Report 1. The supporting data for a petition shall be assernbled in a professional report and shall include appendices of the data and calculations used to demonstrate that the ground water is not connected to the surface water system or that the ground water otherwise meets the statutory definition of nontributary ground water as set forth at section 37-90-103(10.5), C.R.S. 2. A detailed map of the proposed nontributary area shall accompany the report and shall be overlain on a standard U.S.G.S. topographic map with scale 1:24000 inches when such area can be shown within the boundary of 7 mile by 14 mile map area. For larger areas, a topographic base map with a scale of 1:50000, 1:100000 or 1:250000 inches may be utilized; using the largest scale possible that will enclose the entire area of the nontributary ground water determination, wells, and locations of data points, surveys, and other features related to the petition. 3. Standard Data Format — For consistency in reporting, the following parameters shall be used as the standard format and units for reporting the stated types of data: Where: L = length (feet); t = time (day). a. Hydraulic conductivity (K) shall be reported in units of L/t (ft/day). b. Transmissivity [T] shall be reported in units of L2/t (ft2lday). c. Water production rate [Q] shall be reported in units of L3/t (ft3/day). d. Specific storage (S$) shall be reported in units of L-1(1/ft). e. Water volume shall be reported in units of L3 (ft3) f. Specific yield, storativity or storage coefficient shall be reported as a ratio. g. Thicknesses (aquifer, formation, etc.) shall be reported in units of L (feet). h. Distances shall be reported in units of L (feet). 4, The Applicant shall submit two paper copies of the report and appendices and one electronic copy, including GIS shape files, in a format deemed acceptable by the State Engineer's Office. Produced Nontributary Ground Water Rules 2 CCR 402-17 8 5. A petition for multiple production zones may be submitted with a single report utilizing data from a source or sources that include the same geographic/geologic area. 17.7 Specific Locations of Nontributary Ground Water in Colorado Ground water in the State of Colorado is legally presumed to be "tributary," or hydraulically connected to surface water in such a fashion so as to require administration within the prior appropriation system in conjunction with surface rights, unless it is demonstrated to be nontributary ground water in accordance with the law. See Simpson v. Bijou Irrigation Co., 69 P.3d 50, 57 n.7 (Colo. 2003). For purposes of administration under section 37-90-137(7), C.R.S. absent a determination made pursuant to Rule 17.5 of these Rules, or other Rulemaking, the State Engineer shall regard all Produced Water within the State of Colorado to be tributary, with the exception of the ground water described in Rule 17.7.A through D. A. The Denver Basin The State Engineer shall regard the bedrock aquifers of the Denver Basin (the Dawson, Denver, Arapahoe, and Laramie -Fox Hills) to be nontributary only where shown to be nontributary by the Denver Basin Rules, 2 CCR 402-6. Pursuant to section 37-90- 103(10.7), C.R.S., the State Engineer shall regard all remaining ground water in the bedrock aquifers of the Denver Basin subject to the Denver Basin Rules to be not nontributary. B. Water Rights Found to be Nontributary by a Valid Court Decree The State Engineer shall regard all water rights that are decreed nontributary by a court to be nontributary only to the extent provided by the court decree and only insofar as such water is used in a manner wholly consistent with the terms and conditions of such decree. C. Existing Ground Water Well Permits House Bill 09-1303, Section 3, codified at section 37-90-137(7)(c), C.R.S. provides "[a]ny rules promulgated pursuant to this subsection (7) shall not conflict with existing laws and shall not affect the validity of ground water well permits existing prior to the adoption of such rules." Therefore, the State Engineer shall regard as nontributary all ground water permitted for withdrawal as nontributary ground water pursuant to well permits issued by the State Engineer prior to the adoption of these Rules. D. For the purpose of meeting the objectives in the scope and purpose of these Rules, Rule 17.7.D. identifies geographically delineated areas under which the ground water in only certain formations is nontributary for the limited purposes of these Rules. Small-scale maps showing the extents of the delineated areas and identifying the geologic formations are included as a reference in an appendix to these Rules. Larger -scale maps are available on the Division of Water Resources' website along with an electronic version of these Rules. The small-scale and large-scale maps show identical areas and each are incorporated as part of the Rules. The delineated areas may be viewed through Division of Water Resources' public data viewing tools as they are developed Produced Nontributary Ground Water Rules 2 CCR 402-17 9 and the data files describing the areas are also available for downloading from the Division of Water Resources' website. 1.

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 near the project area. ERO surveyed the project site for 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. Standards Analysis Page 3 OXY USA WTP LP Pond 13 E/W E&P Waste Management Facility 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. 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 Waste 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.

Waiver Requests Page 2 OXY USA WTP LP Pond 13 E/W E&P Waste Management Facility Pursuant to Section 4-118 of the Garfield County Land Use and Development Code, Effective July 15, 2013, Oxy requests a waiver for the standards for Access and Roadways for the Pond 13 E/W Centralized E&P Waste Management Facility. Section 7-107 Access and Roadways The roadway between the end of CR 213 and the Pond 13 facility most closely resembles a Semi -Primitive roadway in Table 7-107 of the Garfield Land Use and Development Code based on the estimated number of average daily trips (ADT) that occur on this road. This road does not meet this standard due to a couple of sections that contain a 13 -percent grade where the maximum standard is 12 -percent. Additionally the surface material consists of native material, road base and gravel where the standard is a gravel surface only. A waiver of standards request shall be considered based on the following criteria: 1. Achieves the intent of the subject standard to the same and better degree than the subject standard: Response: The intent of the roadway standard is to provide safe and adequate access to a development. The Pond 13 Facility will be accessed from CR 213 and then by a series of private roads. These private roads are built and maintained by Oxy for the use of the natural gas industry and provides regular access to numerous facilities in the area. Oxy has spent a considerable amount of effort and capital to assure that the access to their facilities is safe and adequate. Oxy spent $2.5 million to maintain their private road system in 2012 and $371,149.06 for maintenance on the mountain road section in 2012. Oxy has spent over $1 million for maintenance on their private road system and $219,093.19 for just the mountain road so far this year. Oxy has significantly improved both the grade and radius on their road system in recent years. Additionally, the road system is posted with signs to allow only authorized personnel. During drilling and completion activities with higher traffic volumes, a security station is manned to prohibit unauthorized personnel from accessing the road. A security firm has been hired to use radar to enforce the speed limits that are posted on the roads. Chain -up rules are implemented during inclement weather through the use of a web site, call-in number, and a sign at the guard shack. Finally, the road can be closed and operations rescheduled if the weather makes the roadway unsafe. These measures achieve the intent of the subject standard to the same and better degree than subject standards alone. 2. Imposes no greater impacts on adjacent properties than would occur through compliance with the specific requirements of this Code. Response: This private road system does not provide access to residential uses nor is it used by the general public on a regular basis. Oxy does authorize government agencies such as the BLM and CPW, in -holders, those with grazing leases and rights to use their road system. Oxy has not received any complaints from these authorized parties Waiver Requests Page 3 OXY USA WTP LP Pond 13 E/W E&P Waste Management Facility regarding the condition of the road. The waiver of this standard will not create greater impacts on adjacent properties than would occur if it was in full compliance.

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° 32' 59" 39° 32' 49" a 0 O Custom Soil Resource Report Soil Map CO 0 Map Scale: 1:2,150 if printed on A size (8.5" x 11") sheet. 0 25 50 100 Meters 150 0 100 200 400 Feet 600 108° 12' 52 Custom Soil Resource Report MAP LEGEND Area of Interest (AOI) Area of Interest (AOI) Soils Soil Map Units Special Point Features Blowout Borrow Pit Clay Spot Closed Depression Gravel Pit Gravelly Spot Landfill Lava Flow Marsh or swamp Mine or Quarry Miscellaneous Water Perennial Water Rock Outcrop Saline Spot Sandy Spot Severely Eroded Spot Sinkhole Slide or Slip Sodic Spot Spoil Area Stony Spot Very Stony Spot I, Wet Spot A Other Special Line Features Gully Short Steep Slope Other Political Features 0 Cities Water Features Streams and Canals Transportation +++ Rails /wr Interstate Highways US Routes Major Roads y Local Roads MAP INFORMATION Map Scale: 1:2,150 if printed on A size (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 55—Parachute-Irigul complex, 5 to 30 percent slopes Map Unit Setting

The Suitabilities and Limitations for Use section includes various soil interpretations 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 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." 16 39° 32' 59" 39° 32' 49" co O 7389 00 73750 73700 739050 Custom Soil Resource Report Map—Corrosion of Concrete 739100 7391150 73700 73y50 739.300 N 0 0 39° 32' 59" R `J.

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. 19 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 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." 20 39° 32' 59" 39° 32' 49" 7389 00 738.950 739.000 739050 Custom Soil Resource Report Map—Corrosion of Steel 739100 739.150 7391 00 739.250 7391300 N 0 jjr' M c0 41 414 0 0 v 0 M 0 ▪ 00 - 00 00 O 1 J O aco e� # co a 0 W O 0 O N 0 NI- 1 738900 0 738950 739000 739050 Map Scale: 1:2,150 if printed on A size (8.5" x 11") sheet. 0 25 50 100 1 739100 Meters 150 Feet 100 200 400 600 1 739150 1 739200 739250 739300 108° 12' 52 39° 32' 59" 0 O N ▪ 39° 32' 49" Custom Soil Resource Report MAP LEGEND MAP INFORMATION Area of Interest (AOI) Map Scale: 1:2,150 if printed on A size (8.5" x 11") sheet.

The site is shown on the U.S.G.S. Circle Dot Gulch 7.5 -minute topographic map. The water storage 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 8,600 feet above mean sea level. The elevation of Cascade Creek lies at approximately 8,200 feet or 400 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 — Irigul complex, which is 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 60 percent Parachute soil and 30 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 Irigul soil is shallow and well drained and is formed in residuum 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 7 inches thick, and siltstone is Geohydrology Report Page 1 encountered at a depth of about 13 inches. Permeability is moderate and the available water capacity is very low. Runoff is medium or rapid, and the hazard of water erosion is moderate to very severe. According to the Soil Survey the Parachute and Irigul soils are listed as "severe" for shallow excavations due to slope, and shallow depth to bedrock. A `severe' limitation indicates that one or more soil properties or site features are so unfavorable or difficult to overcome that a major increase in construction effort, special design, or intensive maintenance is required. In this case the ponds have been designed with synthetic liners and engineered to overcome these limitations. Since this application is to convert an existing production pond into a Centralized E&P Waste Management Facility, no proposed Facility structures, access roads, or surface water diversion structures will be required. The Facility has been constructed to contain 121,480 barrels of produced water which does not include the required two feet of freeboard, 68,010 barrels for Pond 13 East and 53,470 barrels for Pond 13 West. The Facility utilizes a 60 -mil high-density polyethylene (HDPE) liner and a geocomposite base liner to provide sufficient bedding material for the Facility. Once the Facility is approved by the COGCC for conversion, Oxy will install a sump and sight pipe and a second 60 -mil HDPE liner. The sump and sight pipe will allow for fluid monitoring between the two HDPE liners at the Facility. 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. 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. Geohydrology Report Page 2 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 water storage facility is located on the northeastern limb of the Crystal Creek Anticline. 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). 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 Geohydrology Report Page 3 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 disposal 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 depth to bedrock to mitigate these limitations. Consideration also will 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 1,640 feet to the southwest of the water treatment facility, and Little Creek approximately 1,624 feet to the northeast. The site lies on a drainage divide between Cascade Creek to the southwest and Little Creek to the northeast. If a produced water spill were to occur and leave the site, it is expected that it would flow toward Cascade Canyon. Oxy USA WTP had another permitted pit named the MCM #83-92 Pit (COGCC facility ID #273647) located approximately 1,130 feet to the north. The MCM #83-92 pit is shown as being closed on the COGCC GIS database. 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 4, Township 6 South, Range 97 West. However, there are springs shown in adjoining Section 3, Section 5, Section 9 Section 10, Township 6 South Range 97W, and in Section 36, Township 5 South, Range 97 West, of the 6th Principal Meridian. These springs are all located at elevations of less than 8,400 feet and most are closer to an elevation of 8,200 feet above mean sea level. Geohydrology Report Page 4 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 8,600 feet. Cascade Canyon is the nearest surface water and lies at elevations of 8,200 feet to 8,400 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 4, Township 6 South, Range 97 West. There are no permitted water wells in close proximity to the site. The nearest permitted water wells are shown in Section 5, Township 6 South, Range 97 West, and are located across the Conn Creek drainage from the proposed site. These wells are identified as belonging to Williams Production RMT, Cliffs Engineering, and Cities Service Oil and Gas Corp. Some of these wells appear to have been abandoned, and others appear to be used as monitoring wells. They are all located at an elevation of approximately 8,400 feet above mean sea level. 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. Geohydrology Report Page 5 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. 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. 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. Olsson Associates, Inc. w�u.� a) /74x James W.

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 Sections 3 and 4, Township 6 South, Range 97 West of the 6th PM; UTM NAD 83 Zone 12N, 739145m Easting, 4381365m Northing; Latitude, Longitude: 39.548748°N, - 108.216934°W; USGS Circle Dot Gulch, CO Quadrangle. Oxy is the surface owner. The site contains an existing waste water evaporation pond with fencing for site security purposes, including but not limited to wildlife exclusion. Flagging deterrents are installed to discourage birds from accessing the pond. Oxy proposes several site modifications to improve long-term capacity and conditions at Pond 13 E/W. There are no proposed changes to disturbance footprint or type, timing, or number of vehicles accessing the site. The site is currently manned intermittently, as needed to support completion activities; this level of staffing is anticipated to continue. Pond 13 E/W 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 remove the existing pond liner (disposal of E&P waste will be in accordance with COGCC regulations); 2. Conduct geotechnical survey work of the pond base material and make bedding improvements if recommended; 3. Install a geocomposite clay liner; 4. Install a 60 mil liner; 5. Install a leak detection system; Consultants in Natural Resources and the Environment Page 2 6. Install a new primary 60 mil liner and hydro -test the liner and leak detection system; and 7. Drill three new groundwater monitoring wells; Activity one will take up to two weeks to complete; activities 2 through 6 would take up to five weeks to complete; and activity 7 would take approximately one week to complete. ENVIRONMENTAL SETTING Pond 13 E/W occurs on a slightly -southern aspect at an approximate elevation of 8,400 feet above sea level (Figure 2). The existing pond location and parking/access areas consist of graveled and maintained surfaces with minimal to no vegetation. These developed areas are surrounded by aspen (Populus tremuloides) forest to the north, across the road, and mixed mountain scrub -shrub habitat on the other three borders. The scrub -shrub habitat is dominated by sagebrush (Artemesia tridentata sp.) and Gambels oak (Quercus gambelii), with several narrow stringers of aspen (Populus tremuloides) occurring intermittently along the adjacent drainages. The project area was moderately to heavily grazed at the time of the site visit, particularly toward the southern boundary. Dominant vegetation in the Pond 13 E/W vicinity is shown in Table 1. Table 1. Vegetation observed near Pond 13 E/W. Common Name Scientific Name Serviceberry Amelanchier alnifolia Sagebrush Artemisia tridentata sp. Lupine Lupinus sp. Indian paintbrush Castilleja sp. Gambels oak Quercus gambelii Aspen Populus tremuloides Yarrow Achillea lanulosa Wheatgrasses Thinopyrum spp. Rye Elymus spp. Crested wheatgrass Agropyron cristatum Rabbitbrush Ericameria nauseosa Mountain brome Bromus marginatus Noxious Weeds No noxious weeds were observed at the time of the site visit. However, the site visit was performed early in the season, and germination and emergence was minimal. FRO Resources Corporatior.

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 within a greater sage grouse production area (COGCC 2013, CPW 2013; ERO Figure 3). Most of the project area is disturbed, with graded slopes, pad areas, facilities, and steep cut/fill slopes. Areas within the mapped project area (see Figure 2 and 3) are lacking in suitable cover and bunch grasses required for sage -grouse production and forage. Some potential sage -grouse habitat occurs near the project area. FRO Resources Corporatior. Page 4 Based on ERO's site review, sagebrush stands within and surrounding the Pond 13 E/W project area are not anticipated to provide for sage -grouse life cycle needs. They are poor sage -grouse habitat for the following reasons: 1 Limited 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. Overall, the site contains relatively poor brood -rearing habitat for greater sage - grouse. The site and vicinity (see Figure 2, Project Area) 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 13 E/W project envelope is disturbed or developed. 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 COGCC/CPW maps identified no sensitive ungulate habitat within or in the vicinity 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. 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. FRO Resources Corporatior. Page 5 IMPACT ANALYSIS The following sections evaluate 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. 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. Implementation of the Noxious Weed Management Plan minimizes the risk of the spread of noxious weeds. TEPC Species No federally threatened, endangered, proposed, candidate, or 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. 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 13 E/W; 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. Implementation of wildlife flagging, including appropriate spacing/interval, will be negotiated with COGCC as part of the Form 28 approval. No new surface disturbing activities are proposed as part of the Pond 13 E/W 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: FRO Resources Corporatior. Page 6 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. 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 project activities. If surface disturbance is anticipated, ERO recommends that new temporary disturbance areas be reseeded with an appropriate seed mix similar to 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.

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.?

When using automobile(s), 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 rwo vehicles are available, place then[ in vehicle -1 and =2 positions, etc. Ilse any additional vehicles (if more than 5 available) to illuminate flight and land- ing surface obstacles. At night, assure that spotlights, floodlights, vehicle lights, and handlights used to define the 12 and obstacles Are not pointed toward the helicopler.Turn off non-essential lights. 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 veru helpful in finding accident locations and do not have a detrimental effect on the pilot's night vision. ® ® ® Keep approach/departure path free of obstructions.

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 for helicopters responding to these accidents also require spe- cial considerations. Helicopter medical craws normally do not carry protective suits 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 be poisoned and the engines could develop mechanical problems, or cause an explosion or tire, Never assume that the crew has already been informed of the 1-iazmat situation. Hazardous materials of concern are toxic, poisonous, flamma- ble, explosive, irritating, or radioactive in nature. Patients exposed to hazardous materials will require decontamination prior to air transport 10 avoid contamination of die crew and aircraft. Sonne radioactive materials are more dangerous than others, depending upon the type and amounts of those materials.

The upgrades triggers a review of air permitting regulatory (local, state, and federal) requirements. Oxy has hired an air consultant to prepare a Reasonably Available Control Technology (RACT) analysis for determination of appropriate control of hydrocarbons from the produced water and flowback water storage impoundments. The RACT analysis covers the following facilities: - Pond 10, Pond 13 East and West, and Pond G. Once the RACT control method and facility wide potential emissions are identified and analyzed, Oxy will respond accordingly, which may include preparing and submitting any required APENs to the CDPHE. The target completion and submittal date for this activity is November 30, 2013. Oxy will provide the Garfield County Community Development Department (CDD) with the results of the RACT analysis and if APEN application submittal's are required, Oxy will also provide them to CDD. Copies of approved APEN's will be provided to CDD. Please contact me if you have any questions, comments, concerns, or if you require additional information.

Included in this package are: 1. Response to questions. 2. Revised application with changes to the waiver requests. 3. Deed to the parcel which was omitted from the original application. 4. Revised Waiver Request. 5. Water Supply Plan including Nontributary Ground Water Analysis. 6. Wastewater Management Plan. 7. Oxy Mesa Operational Map (source of fluids and transportation pipelines). 8. Revised Project Description. 9. Revised Vicinity Map. 10. Revised Site Plan. 11. Signed Geohazard Report. 12. Letter from Oxy regarding Air Quality Permitting. Please let us know if you need any additional information. Be advised that Craig Richardson is no longer with Olsson. I will be representing Oxy for this and future land use permitting. Thank you for your consideration of this application. Sincerely, Jeff Hofman, AICP Associate Scientist Cc: Oxy File 760 Horizon Drive, Suite 102 TEL 970.263.7800 Grand Junction, CO 81506 FAX 970.263.7456 www.olssonassociates.com OOLSSON ASSOCIATES OXY USA WTP LP Pond 13 E/W Waste Management Facility NTC Response In regard to Garfield County's Not Technically Complete Letter dated August 28, 2013, Oxy has prepared the following responses: 1. GarCo Comment: Is this application resulting from a violation? It does not appear that the existing ponds are located within the area of a COGCC-approved well pad, if not located on a pad the pond would be required to obtain County permitting prior to construction. Can you provide information on this issue? Response: There is no COGCC violation. This is a COGCC approved Form 15 site. This facility is located immediately adjacent to Oxy's 604-44 pad (COGCC Facility ID: 335849). 2. GarCo Comment: The request for waiver of submittal requirements is vastly different from a request of waiver of the standards contained in the LUDC. A waiver of submittal of the Landscape Plan does not negate the requirement to satisfy the standards of the code contained in 7-303. The Director of Community Development may waive submittal requirements however only the BOCC may waive compliance with minimum standards. If you are requesting a waiver from the standard please add that to the application form and provide adequate justification for the Board to make a decision on the waiver. Response: We are requesting a waiver of submittal for the Landscape Plan (please see the Waiver Requests section of the application). No landscaping is being proposed for this site as it is located in a rural and remote area of Garfield County. The site is within a large property and only accessible via a private road system. We have addressed the landscape standards on page 7 of the Standards Analysis. If a Landscape Plan waiver is not required, please disregard the request. 3. GarCo Comment: The request for waiver of submittal of a Water Supply Plan and the Wastewater Management and System Plan are not appropriate and therefore the waiver is not granted. Regardless of the fact that you provide no information in support of the request for waiver the information in a Water Supply Plan and Wastewater Treatment Plan is necessary to determine if the water and wastewater systems proposed for the site are sufficient to serve the project. These plans are required even if no potable water or ISDS is planned, as it is these reports that will provide evidence that bottled water / porta-potties are sufficient to serve the intermittent employees at the site. Therefore please provide information compliant with Sections 4-203 (M) and 4-203 (N) of the LUDC. Response: We have removed the indication for a waiver of the submittal requirement for a Water Supply Plan and the Wastewater Management and System Plan from the Application form. Please see the Water Supply Plan and Wastewater Management and System Plan sections of the application for these submittal items. 760 Horizon Drive, Suite 102 TEL 970.263.7800 Grand Junction, CO 81506 FAX 970.263.7456 www.olssonassociates.com OXY USA WTP LP October 8, 2013 Pond 13 E/W Waste Management Facility 4. GarCo Comment: There is no indication that the project site is located within a Special Flood Hazard Area, nor is this a request for a PUD >5 acres or proposing 50 lots or greater, so there is no requirement for a Floodplain Analysis. This submittal requirement will not be waived as it simply is not applicable to this site. Response: Please disregard the waiver request for a Floodplain Analysis as it is not required for this application. 5. GarCo Comment: The Landscape Plan is a submittal requirement for all Limited Impact applications however Section 7-303 excludes industrial uses from a requirement to meet Landscape Standards making this submittal requirement 'not applicable'. No waiver is required. Response: Agreed. Please see response to Item 2 above. 6. GarCo Comment: The remainder of the items requested to be waived as submitted requirements- the Improvements Agreement and Development Agreement - are hereby waived as submittal requirements. Response: Noted. 7. GarCo Comment: The pre -application summary lists the parcel as being 10,303 -acres, the application states that the site is 640 -acres and the parcel number provided is shown as a 1,053.08 -acre parcel. Please clarify. Response: The 10,303 acreage listed in the Preapplication Summary is incorrect. It is based on contiguous parcels of which this parcel, 216904400003, is a small part. The project is located on this smaller 640 acre parcel. This is the parcel referred to throughout the application. The 1,053.08 acre parcel is a larger parcel owned by Oxy that is adjacent to the project parcel. 8. GarCo Comment: The applicant is responsible for demonstrating legal and physical access to the site- are there easements or agreements related to the private road system? What are the physical characteristics of the road and does it meet County Standards in Article VII? Response: No easements exist for the private road system. It is completely contained within Oxy owned property. Please see the Access and Roadways Standards Waiver Request. 9. GarCo Comment: The application states that the fluids will be transported via pipelines to the ponds. How will the water be transported post -storage when it will be re -used? In the same pipeline? Trucked? This information is necessary to determine the potential impacts of the project. Response: All water will be transported to and from the site via water distribution pipelines. Please see the attached GIS map indicating distribution and gathering pipelines and well pad locations. The same water pipelines serve as inflow and outflow pipelines. 10. GarCo Comment: It does not appear that a full description of the proposal was included in the Project Description section of the submittal. There appears to be a significant amount of storage that may or may not be related to, or accessory, to the use of the impoundment- two areas on the site plan appear to be dedicated for storage yet no mention of this is found in the project description. Please provide additional information on what will be stored there and if the storage is directly related to the impoundments. If additional equipment, materials, NTC Response Page 2 OXY USA WTP LP October 8, 2013 Pond 13 E/W Waste Management Facility and supplies unrelated to the impoundment are proposed to be located on this site then a request must be made to add the use of "storage" into this application. Response: Please see revised Project Description. 11. GarCo Comment: The site plan requirement has not been adequately addressed as indicated by the items below: a. Sheet 1 of 2 is unnecessary as a smaller vicinity map would suffice. It is confusing to have a "Site Plan" at a scale of 1" = 2000'. Response: Sheet 1 of 2 has been removed. b. Location and dimension of easements or location of the pipelines transporting the water to the site are required - one appears to be located at the north end of the project area, is this the only pipeline that will serve these impoundments? Response: The site plan has been revised. c. Does the legal description of the project area (Detail A Area) include 21.47 -acres? The legal description doesn't include the acreage so it is difficult to ascertain what it incorporates. The pre -application summary indicates a project area of 17.67 -acres which is resulting in confusion; Response: The legal description is for the whole parcel that the project is on. The Project Area Description below Detail A is the legal description for the project area and includes the square footage and area of the project. d. Elevation drawings showing existing grade, finished grade, and height of the proposed structures above existing grade are required. Response: The site plan has been revised. e. The location of fencing is shown around the ponds, will the storage areas be fenced? Response: No hazardous material or other items requiring fencing will be kept at the storage area. Fencing is not proposed at this time. 12. GarCo Comment: Provide information and a comprehensive map that indicates location of the wellpads from which the water will be produced, along with the location of pipelines and an indication of all surface owners related to the above. If the well pads and pipes are all on Oxy -owned land then please provide a statement to that effect. Response: A GIS map showing the location of pipelines and well pads is included with this letter and will be included in the referral copies. All pads and pipelines are on Oxy -owned land. 13. GarCo Comment: The NRCS soil survey was provided which indicates the soils type found on-site, however no analysis of that type of soil impact on the proposed development was included.
