OILY USA INC. )ay: a ichae .premn Vice President and General Counsel c( OLSSON ASSOCIATES OXY USA WTP LP Centralized Water Handling Facility and Accessory Storage including Laydown Yards Project Narrative The enclosed Limited Impact Review (LIR) application is intended to facilitate permitting of two (2) proposed land uses according to the Garfield County Unified Land Use Resolution (January 2009) on fee surface lands. The proposed uses are contained within a single parcel, they are interrelated and in close proximity to each other. They are as follows: 1) Water Handling Facility 2) Accessory Storage including Laydown Yards As detailed in this application, OXY USA WTP LP's (Oxy) Centralized Water Handling and Accessory Storage Facility is intended to accommodate Oxy's requirement for disposal, storage, and reuse of produced water resulting from natural gas development activities in its Piceance Basin operations area. The facility is also intended to provide Oxy with areas for general storage and laydown of supplies, machinery, equipment or products and provide accessory storage/warehousing of materials or equipment within a variety of permitted structures. The proposed facility will facilitate the collection, storage, disposal and transfer of produced water from Oxy's natural gas wells. The primary use of the water will be for reuse in Oxy's natural gas drilling and completion operations. Any water that cannot be reused as part of Oxy's operations will be injected into the proposed onsite salt water disposal well that has been properly permitted with the Colorado Oil & Gas Conservation Commission (COGCC), or taken to other appropriate disposal facilities. The facility will be located on Oxy owned property off Oxy's private road about 1.25 miles north of the terminus of Garfield County Road (CR) 213 (Conn Creek Rd). The site is approximately 5.5 miles north of the County Road 204/County Road 213 intersection. The proposed Centralized Water Handling Facility (along with the proposed Accessory Storage) is located in the northwest quarter of the northwest quarter of Section 29, Township 6 south, Range 97 west, in Garfield County, Colorado. Water Handling Facility The proposed Centralized Water Handling Facility will consist of a system of closed -tank gravity separation tanks. The typical closed -tank gravity separation system will comprise of settling tanks, final water handling tanks and include access to the salt water disposal well. Additional ancillary infrastructure will consist of a pump building to house the proposed water pumps, electrical buildings for power phase controls, structures to contain other electrical components and other small structures required to house pump controls including a piping valve control set. 1 Oxy will utilize the closed -tank gravity separation system to recycle water for reuse during their operations in the area. Condensate separated at the facility will be stored in tanks located at the facility. Condensate haul trucks will periodically come and remove the condensate for sales. The facility will also be served by a salt water disposal injection well which will be monitored by Oxy's CC I control room. Further details and facility diagrams are provided in this application. The proposed operation of this facility is intended to reuse and/or dispose of water gathered from Oxy's natural gas well sites in the area. Produced water will be transported primarily via existing water pipelines. In the areas of Oxy's operations not currently serviced by pipelines for produced water, trucks will be utilized for transport of water to the water handling facility. Prior to transport of water to the water handling facility, residual oil or condensate will be allowed to separate by gravity from the produced water and then removed via a series of gravity separator tanks on the well pads. After the first stage of residual oil/condensate removal at the well pads, the water will be piped to the water handling facility. After the water is piped to the water handling facility, it will be stored in a number of tanks which will be configured to allow for additional gravity separation and removal of residual oil/condensate, The water will also have impurities removed as it is passed through a series of filters and an additional 2 -phase separator. The proposed tank batteries provide settling time to allow the remaining oil/condensate to break out and rise to the top of the tanks where the material is then directed into designated oil/condensate storage tanks. The oil/condensate stored in these tanks will then be sold just as it is from typical production sites. The high emission tank system will be a closed vapor control system utilizing one or more enclosed -flame combustors, similar to those used on producing wells, to collect and destroy hydrocarbon emissions. The combustor destruction efficiency will meet or exceed the appropriate CDPHE requirement for air -emission health standards. Oxy will secure all appropriate air quality permits for the operation of these units. From the facility's settling tank batteries, the water will then be pumped to existing storage ponds for future reuse, off-site disposal or to the injection well for onsite disposal. Additionally, Oxy's proposed reuse of this water will alleviate the heavy demand on local sources of water by recycling water back into operations versus obtaining fresh water from local sources for drilling and completion operations. Reuse of water in proximity to where it is generated will also reduce the heavy truck traffic currently traveling down CR 213 and 1-70 to disposal facilities. The water handling and laydown yard facilities will be accessible to Oxy personnel and contractors 24 hours -a -day, 365 -days -a -year. Both the laydown facilities will generally be unmanned; however, daily inspections will be conducted by local operation personnel. This facility will also be permitted as a Centralized E&P Waste Management Facility through the COGCC. The COGCC permit will also contain requirements for environmental protection/mitigation that will be adhered to during the construction and operation of the facility. 2 Accessory Storage and Laydown Yards In addition to the proposed water handling facility, Oxy is also proposing to permit a series of four (4) Iaydown and storage yards. These yards will provide logistical support for operation of the Water Handling Facility and will be an integral part of Oxy's natural gas drilling, completion and production in Oxy's Piceance Basin area production units. The relatively remote nature of Oxy's operations also necessitates the construction of this facility so that equipment and materials may be stored in a central location. The construction of a lay down yard at this location will minimize the need for materials to be transported to the area during times of inclement weather thereby increasing the safety of Oxy's operations. The four (4) storagellaydown yards will range from approximately 2 to 2.7 acres in size. They will be constructed of native soils, and compacted as needed. The surface will be covered with no less than 6 inches of gravel to form a year-round working surface suitable for heavy truck traffic. Each storagellaydown area will have access points to allow safe ingress and egress of truck traffic. The proposed locations will be utilized for the storage of equipment including, but not limited to: production units, tubulars (flow piping, tubing, and casing), excess tankage, miscellaneous valves, fittings, barriers, pit fabric, emergency response materials and other essential items to be used in the drilling, completion, and production processes. They will also be used for staging the transport of tankage utilized in the well completion and stimulation of drilling locations. The storagellaydown yards may also be utilized for the temporary storage of vehicles, heavy equipment and jobsite trailers prior to transport to well pad sites. Two new structures, designed to prevent exposure to the elements and accommodate long term storage of equipment, are also proposed for construction. The first will be a temporary enclosure approximately 50 feet by 70 feet in size. The second proposed structure will be a warehouse. This structure will provide accessory storage/warehousing of materials or equipment associated with Oxy's natural gas drilling operations. The second structure will be approximately 60 feet by 120 feet in size. A jobsite trailer and two temporary storage/fabrication structures and will also be utilized on one of the storage yards. A portable storage shed will be temporarily located on one of the storage yards to accommodate assembly and storage of a variety of operations equipment. Additional details specific to all proposed structures provided in the attached diagrams. All appropriate Garfield County building permits will be secured for any structure that requires permitting. Wastes and trash generated as a result of Oxy's operations will be collected and stored prior to disposal according to waste type at an appropriate waste handling facility. No hazardous wastes are anticipated to be stored on site. The facility also will be covered by Oxy's Spill Prevention, Control and Countermeasures (SPCC) Plan that addresses measures that will be taken to prevent, control and respond to spills. Both the water handling facility and the storagellaydown areas will be included within the common plan of development purposes of Oxy's Storm Water Management Plan. As such, the fill slopes on the pad will be reseeded and revegetated to minimize erosion. BMPs such as silt 3 fence, sediment ponds, rock socks, rock dams, or erosion blankets may be utilized to contain or minimize erosion until the site has been stabilized. 4 Adloiniag 2134 R. 28 W.

Public Access Access to the subject property is from a private road accessed from County Road 213 (Conn Creek RD). There are no historic access points to public lands within the property boundaries. Article IV, 4-502 D.2. Access to Adjoining Roadways County Road 213 intersects with County Road 204 (Roan Creek RD) approximately 5.5 miles south of the proposed facility. Impacts to adjoining roadways are not anticipated. Article IV, 4-502 D.3. Easements All easements within the vicinity of the project area are shown as required on the site plan. The proposed facility will not impact existing easements found on the subject property. Article IV, 4-502 D.4. Topography and Slope As demonstrated on the slope hazards map included as figure 3, the proposed facility is located adjacent to areas of steep slope. The Geologic and Soils Hazards Report included with the supplemental information details the area of concern within the project area. OXY USA WTP LP (Oxy) will implement appropriate mitigation measures to stabilize slopes and control stormwater runoff in order to minimize erosion. Article IV, 4-502 D.5. Natural Features Natural features including soils, vegetation and terrain are detailed in various reports included in the supplemental information. Vegetation primarily consists of widely scattered pinon juniper, sagebrush and mountain shrub. Terrain at the project area varies from flat to moderately steep hillsides. The project area is adjacent to a section of Conn Creek classified as an intermittent stream. (Wildlife and Sensitive Areas Report, WestWater Engineering — Integrated Vegetation and Noxious Weed Management Plan, WestWater Engineering) Article IV, 4-502 D.6. Drainage The proposed facility is situated to the west of Conn Creek on an alluvial fan formed at the base of a steep drainage off of the plateau to the west. Although not a requirement of the Limited Impact Review Process, an Erosion Control, Grading & Drainage Plan was prepared due to the proposed facility's proximity to steep drainage and Conn Creek. Numerous BMP's including culverts, stormwater catch basins and a rock dam are proposed to ensure historic drainage patterns are preserved. This plan has been included under a separate tab for staff review. 1 Article IV, 4-502 D.7. Water The proposed project will not require a source of water during the operation or construction of the facility. Therefore, no demand will be placed on local water resources. The proposed water treatment facility will store and treat only water produced from Oxy's natural gas wells in the area. Article IV, 4-502 D.B. Floodplain The project site is not within a floodplain as demonstrated in figure 4. Article IV, 4-502 D.9. Soils A copy of a Natural Resources Conservation Service (NRCS) Custom Soil Resource Report for the project site has been provided under the supplemental material tab for Planning Staff review. Additionally, soil characteristics are detailed in §2.2 of the Wildlife and Sensitive Areas Report, prepared by WestWater Engineering (WWE). The two soils types found on-site are Happle very channery sandy loam and Happle-Rock outcrop association. The project location is primarily underlain by Happle very channery sand loam. The NRCS soils report for this area provides information regarding the suitability or limitations of these soils for the proposed use --- shallow excavations and roads. The primary limitations identified by the NRCS for this proposed use are based on the slopes, limited depth to bedrock and the potential for cutbanks to cave. These limitations are most pronounced in the northwestern portion of the site where a storage facility is proposed. Consideration will be given to the design and construction of this facility to ensure that slopes are graded appropriately to minimize the potential for cutbank caving. (Geologic and Soil Hazards Report, Olsson Associates) Article IV, 4-602 D.10. Hazards The proposed Water Treatment and Storage Facility is situated to the west of Conn Creek on an alluvial fan formed at the base of a steep drainage off of the plateau to the west. Ground cover consists primarily of dry grasses and sagebrush, with some pinon. No geologic hazards have been mapped by Garfield County in this area and no faults or other hazards are evident on the Geologic Map of Colorado. However, evidence of land instability is visible in proximity to the site. Rock fall from the canyon walls is common. The wide, shallow, and steep channels of streams and drainages experience flash flooding and occasional debris flow during prolonged or extreme storm events. The nearest perennial surface water feature is Conn Creek which flows north to south and is located adjacent to the proposed facility, however, numerous dry channels, including a relatively Targe drainage immediately to the west of the facility, transect the steep slopes to the west of the facility and will carry water during storm events. Geologic hazard potential is likely high to very high. In order to mitigate this concern consideration of rock fall and debris flow has been considered in the design and construction of the facility. 2 Article IV, 4-502 D.11. Natural Habitat Potential impacts to natural habitat are discussed in detail within the Wildlife and Sensitive Areas Report prepared by WWE. WWE gathered information of critical habitats for federally - listed threatened, endangered, and candidate fish and wildlife species from the Federal Register, U.S. Department of the Interior, U.S. Fish and Wildlife Service. In addition to data collected during the field survey, wildlife habitat maps from Colorado division of Wildlife and Natural Diversity Information Source referencing mule deer, elk, black bear, mountain lion and state -listed threatened, endangered and species of special concern were utilized and incorporated into the report. As outlined in this report. No federally listed threatened, endangered or candidate wildlife species are known to occupy the project area. WWE biologists identified one (1) species included as a state -listed threatened, endangered or special concern species that could potentially occur within or be affected by the proposed project. The habitat of Colorado River cutthroat trout is listed as perennial mountain streams on the Roan Plateau in drainages of the Parachute and Roan Creeks. WWE research determined that the project area is not known to Colorado Division of Wildlife (CDOW) to be habitat for this species. There were no Birds of Conservation Concern observed during the site -survey conducted by WWE biologists. An unoccupied accipiter nest was observed to the northeast of the project area. There are no known Bald Eagle nest sites within the project area. The Greater Sage -Grouse is identified by the Bureau of Land Management and CDOW as a species of Special Concern. The proposed project area is not located within the normal habitat for Greater Sage -Grouse. No signs of sage -grouse were observed during the site survey. The project area is situated within the mule deer and American elk overall and winter range. Deer droppings and fresh tracks were observed throughout the project area. Produced water stored on-site for treatment will be contained within a tanked system at all times eliminating the attraction of elk and mule deer on-site. The proposed project area is relatively small in size and will not impact the movement or migration within the identified ranges. The project area is not mapped by the CDOW as a potential black bear or mountain lion conflict area. Due the size of the proposed facility and existing activity in close proximity to the project area, impacts to natural habitat are anticipated to be minimal. Article IV, 4-502 D.12. Resource Areas A Class 1 cultural resource inventory was prepared by Flattops Archaeological Consultants (supplemental material). The inventory determined that no protected or registered archaeological, cultural, paleontological or historic resources exist on the subject property. 3 Article IV 4-502 E Impact Analysis OXY USA WTP LP Centralized Water Handling Facility and Accessory Storage including Laydown Yards Limited Impact Review %OLSSON ASSOCIATES OA Project No. 009-0420 February 2010 826 21 '/z Fio44 _Grand -Jun` tr 6"3 OLSSON ASSOCIATES Article IV, 4-502 E.1.

The two soils types found on-site are Happle very channery sandy loam and Happle-Rock outcrop association. The project location is primarily underlain by Happle very channery sand loam. The NRCS soils report for this area provides information regarding the suitability or limitations of these soils for the proposed use -- shallow excavations and roads. The primary limitations identified by the NRCS for this proposed use are based on the slopes, limited depth to bedrock and the potential for cutbanks to cave. These limitations are most pronounced in the northwestern portion of the site where a storage facility is proposed. Consideration will be given to the design and construction of this facility to ensure that slopes are graded appropriately to minimize the potential for cutbank caving. (Geologic and Soil Hazards Report, Olsson Associates) Article 1V, 4-502 E.S. Geology and Hazard Oxy's proposed facility is situated to the west of Conn Creek on an alluvial fan formed at the base of a steep drainage off of the plateau to the west. Ground cover consists primarily of dry grasses and sagebrush, with some pinon. No geologic hazards have been mapped by Garfield County in this area and no faults or other hazards are evident on the Geologic Map of Colorado. However, evidence of land instability is visible in proximity to the site. Rock fall from the canyon walls is common. The wide, shallow, and steep channels of streams and drainages experience flash flooding and occasional debris flow during prolonged or extreme storm events. The nearest perennial surface water feature is Conn Creek which flows north to south and is located adjacent to the proposed facility, however, numerous dry channels, including a relatively large drainage immediately to the west of the facility, transect the steep slopes to the west of the facility and will carry water during storm events. Geologic hazard potential is likely high to very high. In order to mitigate this concern consideration of rock fall and debris flow has been considered in the design and construction of the facility. Article IV, 4-502 E.6. Effects on Exiting Water Supply and Adequacy of Supply The proposed facility will store only water produced from Oxy's natural gas wells in the area, therefore, no supply of water is required and no demand will be placed on local water resources. Article IV, 4-502 E.7. Effects on Groundwater and Aquifer Recharge Areas The facility has been designed to eliminate the potential of produced water or fuels impacting surface or ground waters. All tanks used to store the produced water and fuel will have secondary containment. The facility will be covered under Oxy's area wide Spill Prevention Control and Counter Measures plan (SPCC) and Colorado Department of Public Health and Environment (CDPHE) construction stormwater management plans and Colorado Oil and Gas Conservation Commission.(COGCC) post construction stormwater management plans. 3 A single injection well (identified as the Cascade Creek #629-1) is located on the proposed facility. This injection well will be utilized to dispose of a portion of the water treated and stored at this facility. Oxyrs Cascade Creek 629-1 injection well has been permitted and approved for operation by the COGCC. The COGCC review process is intended to address any issues related to potential impacts to groundwater. This well will be operated in strict accordance with COGCC regulations and the approved permit criteria. Please see the attached injection well permit application package and the approved COGCC permit for additional details. The assigned injection well permit number is 159281. Environmentally sound and safe operation of Oxy's Cascade Creek 629-1 injection well is assured with the implementation of the following leak detection and emergency controls: • Low Suction Press Alarm, monitors suction pressure to the pump • Low and High Discharge Alarms, which monitors downstream pressures • Bradenhead Pressure Alarm, monitors surface casing pressure • Wireless Casing Pressure Monitor/Transmitter, monitors casing pressure • Wireless Tubing Pressure Monitor/Transmitter, monitors tubing pressure • Remote Telemetry Unit, the injection well is equipped with a standalone remote telemetry unit that would allow the injection well to continue to operate in the event that the operator loses contact with the injection well; it is solar powered and has a backup battery power supply. Each control is designed to notify the operator regarding any issues with the injection well and the controls have the capability to remotely shut in the well, without operator assistance. In addition to the above injection well controls, the equipment supporting the Cascade Creek 629-1 injection well also have controls, which consist of: • Filter Pod Pressure Alarms, monitors filters and notifies operator when to replace filter • Pump(s) supporting the injection well are equipped with Programmable Logic Controls, which monitors the pump package and pressures • The pump(s) are also equipped with Low Oil Level Alarms and monitor flow rates, including the maximum daily pressure/volume (as set by the COGCC). Article IV, 4-502 E.8. Environmental Effects Environmental effects resulting from this use are addressed in the Wildlife and Sensitive Areas Report prepared by WWE. Field surveys were performed by WWE biologists on April 6th, 2009. The report concludes that there are no federally listed threatened, endangered, or candidate wildlife species known to occupy the area on or around the project area. Due to the relative small size of the project area, minimal impacts to wildlife are anticipated. The WVVE report is included in the supplemental information for staff review. The existing environmental conditions are described in the Land Suitability Analysis and various reports contained in the supplemental information. Each of the factors that are required to be considered in this Impact Analysis is discussed below. 4 Article IV, 4-502 E. 8, a - Determination of the long term and short term effect on flora and fauna. The impacts to flora and fauna from this facility and measures that can be taken to mitigate those impacts are described in detail in the Wildlife and Sensitive Areas Report and Integrated Vegetation and Noxious Weed Management Plan prepared by WWE. Oxy will implement the mitigation measures prescribed by this document as needed. Article IV, 4-502 E. 8. b. - Determination of the effect on significant archaeological, cultural, paleontological, historic resources.

Traffic A Basic Traffic Analysis has been prepared demonstrating the impacts of the proposed facility (supplemental materials tab). Due to the limited impacts of traffic generated by the proposed use, improvements to the County Roads 213 or 204 are not required. The proposed use will not increase traffic by 20% on any County, State or Federal roadway or intersection. Article IV, 4-502 E.l0. Nuisance Adjacent lands will not be impacted by the generation of vapor, dust, smoke, noise, glare or vibration. This use will comply with Colorado Revised State Statute regarding noise at all times. 5 Article IV, 4-502 E.11. Reclamation Plan Reclamation Plan Oxy estimates that the proposed facility will be in operation for an anticipated period of approximately twenty-five (25) years during development and production of Oxy's Garfield County operations. Upon termination. of the development and production activities, the project area 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 CDPHE Stormwater Permit for the site. 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 approved native seed mixtures identified below: 6 rbed Areas Reclamation Common Name Scientific Name Pounds Pure Live Seed (PLS) per acre Western wheatgrass Pascopyrum smithii 8.0 Sideoats Grama TOTAL PLS 8.0 Final Reclamation Seed Mixture 1 Common Name Scientific Name Pounds Pure Live Seed (PLS) per acre Alkali Sacaton Sporobolus airoides 1.0 Sideoats Grama Bouteloua curfipendula 2.0 Basin Wildrye Leymus cinereus 2.0 Western wheatgrass Pascopyrum smithii 4.0 TOTAL PLS 9.0 Final Reclamation Seed Mixture 2 and 3 Low -Elevation Salt -Desert Scrub/Basin Big Sagebrush Common Name Scientific Name ' Form PLS. lbsiactex Fourwing Saltbush Awl -pia; canescens Shrub 1.9 Shadscale Atriplez confer1ifolia Shrub 1.5 Galleta Pleuraphis (Hiiariaj jarnesii Bunch 2.5 Alkali Sacati'art Sporabolus air oides Builth 0.2 Sfreambauk \Vlieat ass Elynnas lanceolatusssp. psammophilus, Agropyron npanum Sod -forming 2.5 Slender Wheatgzass Elynnts trachycauius, Agropyron trachycaulutn Bunch 1.8 Sandberg Bluegrass Poa sandbergii (Poa secunda) Bunch 0.3 *Based on 45 pare live seeds (PLS) per square foot, chili -seeded.

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: • 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. 9 • 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 025 — 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. Mulch: With 24 hours of reseeding (weather permitting) hydromulch will be applied to all reclaimed and reseeded surfaces. Areas where the erosion potential is such that biodegradable blankets will be used will not be hydromulched. 10 OXY USA INP LP Material Handling and Storage, Article VII Standards OLSSON ASSOCIATES Applicable Standards Olsson Associates (Olsson) on behalf of OXY USA WTP LP (Oxy) had reviewed the Garfield County Applicable Standards in support of Oxy`s proposed Water Treatment and Storage Facility (facility).

The location for the proposed Water Treatment and Storage facility is underlain by the lower part of the Green River Formation. This part of the Green River Formation consists of shale, mudstone and sandstones. The cliffs and plateau to the west of the location are comprised of the Parachute Creek Member of the Green River Formation and consist of oil shale, sandstone and mudstone. The rocks of the Green River Formation are the parent material for the soils that occur at this location. Figure 2 provides a soils map for the location of the proposed facility. This location is primarily underlain by soils of the Happle very channery sandy loam, 3 to 12 percent slopes (soil unit 44 on Figure 2), however, the northwestern most storage area is underlain by the Happle-Rock outcrop association 25 to 65 percent slopes (soil unit 46 on Figure 2). The Happle very channery sandy loam is a very well drained soil that is typically up to 60 - inches thick. The Happle-Rock outcrop association is a well drained soil that may reach 60 -inches thick but is typically much thinner and underlain by bedrock. Limitations of these soils in relation to the proposed project are discussed in detail below. Geologic and Soil Hazards The Natural Resources Conservation Service (NRCS) soils report for this area provides information regarding the suitability or limitations of these soils for the proposed use — shallow excavations and roads. The primary limitations identified by the NRCS for this proposed use are based on the slopes, limited depth to bedrock and the potential for cutbanks to cave. These limitations are most pronounced in the northwestern portion of the site where a storage facility is proposed. Consideration will need to be given to the design and construction of this facility to ensure that slopes are graded appropriately to minimize the potential for cutbank caving. In addition, the Happel -Rock outcrop association soils are noted as having a severe erosion hazard. Design considerations to stabilize slopes and control drainage and stormwater runoff will be required to minimize erosion. The NRCS also identifies these soils as having very limited capability for landscaping due to high gravel content and the droughty nature of this area. This limitation will need to be considered in the design and implementation of any landscaping for this facility. The proposed Water Treatment and Storage Facility is situated to the west of Conn Creek on an alluvial fan formed at the base of a steep drainage off of the plateau to the west. Ground cover consists primarily of dry grasses and sagebrush, with some pinon. No geologic hazards have been mapped by Garfield County in this area and no faults or other hazards are evident on the Geologic Map of Colorado. However, evidence of land instability is visible in proximity to the site. Rock fall from the canyon wails is common. The wide, shallow, and steep channels of streams and drainages experience flash flooding and occasional debris flow during prolonged or extreme storm events. The nearest perennial surface water feature is Conn Creek which flows north to south and is located adjacent to the proposed facility, however, numerous dry channels, including a relatively Targe drainage immediately to the west of the facility, transect the steep slopes to the west of the facility and will carry water during storm events. Geologic hazard potential is likely high to very high and consideration of rock fall and debris flow need to be considered in the design and construction of the facility.

Prepared for: OXY USA WTP, LP (OXY) 760 Horizon Drive, Suite 101 Grand Junction, CO 81505 Prepared by: WestWater Engineering 2516 Foresight Circle #1 Grand Junction, CO 81505 In coordination with: Cordilleran, a division of Olsson Associates May 2009 1.0 INTRODUCTION 1.1 Project Description Cordilleran Compliance Services, a division of Olsson Associates, has requested WestWater Engineering (WWE) to provide a Wildlife and Sensitive Areas Report for OXY USA WTP; LP (OXY). OXY is proposing to develop a water treatment and storage facility, which lies approximately 12 miles north of DeSeque, Colorado in Section 29, Township 6 South, Range 97 West (Figure 1). The treatment and storage facility is within Garfield County, Colorado and is located on private land. The facility is approximately 17 acres in size, and is located adjacent to Conn Creek. Most of the facilities associated with the project have already been constructed, and the time of construction required to complete the project will be minimal. Access to the project site is currently available via County Road 204 (Roan Creek Road), County Road 213 (Conn Creek Road), and a private road. The primary use of the site and surrounding area is rangeland, pasture, wildlife habitat, and natural gas extraction/development. The general project area is currently undergoing rapid natural gas development including driIIing of wells, construction of pipelines, compressors, and access roads. 1.2 General Survey Information In preparation for developing the following report, WWE biologists performed field surveys and assessments of wildlife, wildlife habitats, and habitats for sensitive plant species on the proposed project area. WWE conducted surveys on April 6, 2009. The purpose of the surveys were to determine the wildlife and sensitive plant species that occupy the project area at varying periods during the year, and species that would potentially be impacted as a result of the water treatment and storage facility and operational activities. Factors considered include: 1) soil type and texture; 2) existing land management; 3) absence or presence of wildlife and plant species including raptors, sage -grouse and other sensitive birds species; 4) special designations by Federal and State wildlife agencies; and 5) the existing natural vegetation community. This report provides written documentation that describes survey findings as well as recommended mitigation measures. 2.0 LANDSCAPE SETTING 2.1 Vegetation Vegetation communities around the water treatment and storage facility are a mixture of widely scattered pinon juniper, sagebrush dominated shrublands in the valley floor, and mountain shrub on the adjacent steep slopes. Agricultural meadows are present on private Iands only, about 0.1 miles south of the project location. Pifion-juniper woodlands are dominated by Utah juniper (Juniperus osteosperma) and occasional pifion pine (Pinus edulis) and are mixed with Wyoming sagebrush (Artemisia tridentata wyomingensis), forbs, and grasses. The water treatment and storage facility boundaries are immediately adjacent to Conn Creek, and therefore, riparian communities are present in the project area. Vegetation along the creek consists of cottonwood WestWater Engineering Page 1 of 20 May 2009 (Populus spp.), greasewood (Sarcobatus vermiculatus), Rabbitbrush (Chrysothamnus nauseosus), willows (Salix spp), alder (Alnus spp.), Gambel oak (Quercus gambelii), box -elder (Negundo aceroides) and basin big sagebrush (Artemisia tridentata tridentata). The shrublands within the project area are characterized by basin big sagebrush, greasewood, and green rabbitbrush (Chrysothamnus viscidiflorus). Non-native downy brome (Bromus tectorum) and annual wheatgrass (Eremopyrum triticeum) dominate the understory for this shrubland community. The adjacent mountain shrub vegetation consists primarily of serviceberry (Amelanchier alnifolia), Gambel's oak, and Wyoming big sagebrush with an understory of grasses and forbs. Bare ground is also present throughout much of the site due to impacts from development. The climate for the Piceance Basin is considered semi -arid with a wide range of temperatures and precipitation. The closest weather station is at the Altenbern Ranch on Roan Creek, which has provided reliable records to the National Oceanic and Atmospheric Administration (NOAA) since 1948. The average annual precipitation at the ranch is 16.41 inches, with a record low temperature of minus 38 degrees Fahrenheit and a record high temperature of 104 degrees Fahrenheit (NOAA website: www.noaa.gov). The average annual precipitation at the upper elevations in the project area should equal, and likely exceed, that observed along Roan Creek. 2.2 Soils Soil types include loams and sandy to gravelly loams that overlay broken shale derived from the Green River Formation. This formation is visible in the sheer canyons of Roan and Parachute Creek and the Roan Cliffs overlooking the towns of Rifle, Parachute, and DeBeque, Colorado. In many areas, soil profiles are shallow, with only 12-24 inches of soil overlying deep, broken shale deposits. Soil types and the vegetation supported vary with elevation and slope aspect. Mapped soil types, as published by the Natural Resources Conservation Service (NRCS), U.S. Department of Agriculture (USDA), were reviewed to determine the soil types and vegetation characteristics of the project site and surrounding property (NRCS 2009). Two soil types are found in the project area and include the following: 1. Happle very channery sandy loam with 3 to 12 percent slopes. 2. Happle-Rock outcrop association, with 25 to 65 percent slopes. 2.3 Terrain The terrain varies from flat to moderately steep hillsides with elevations ranging from about 5,900 ft to about 6,200 ft. The water treatment and storage facility lies adjacent to Conn Creek, the section of which is classified as an intermittent stream. No water was flowing in the creek at the time of the survey. Natural gas exploration and development is resulting in landscape/watershed scale habitat fragmentation. The physical loss of habitat is due primarily to the increase in roads, well pads, pipelines, compressor stations, and other ancillary facilities required to produce and transport natural gas. Additionally these activities contribute to the introduction and/or spread of invasive species. Generally the undisturbed area retains good vegetation cover, including native grasses such as Sandberg bluegrass (Poa sangbergii), Indian ricegrass (Achnatherum hymenoides), bottlebrush squirreltail (Elymus elmoides), galleta (Haiaria jamesii), and needle -and -thread grass (Hesperostipa comata), introduced and invasive grasses including downy brome, annual WestWater Engineering Page 2 of 20 May 2009 wheatgrass, and crested wheatgrass (Agropyron cristatum), as well as forbs and shrubs including sagebrush and greasewood. 3.0 WILDLIFE AND PLANT SURVEYS 3.1 Background Information Descriptions of critical habitats for federally -listed threatened, endangered, and candidate fish and wildlife species were reviewed in the Federal Register, U.S. Department of the Interior, U.S. Fish and Wildlife Service (USFWS). Wildlife habitat (activities) maps, provided via the Internet web by the Colorado Division of Wildlife's (CDOW) "Natural Diversity Information Source" (NDIS), were reviewed and incorporated into this report in reference to mule deer, elk, black bear, mountain lion, and state -listed threatened, endangered and species of "special concern"(CDOW 2008a). A list of Birds of Conservation Concern (BOCC) and their habitats was reviewed. This list is published by the USFWS through.a Memorandum of Understanding with the BLM and the U.S. Forest Service (USFS), which places high conservation priorities for BOCC species (USFWS 2002). Not all of these BOCC species occur regularly in Colorado, some are present only as seasonal migrants. Of those known to breed in Colorado, only a portion are known or suspected to breed within the vicinity of the proposed water treatment and storage facility. Avian literature sources such as the "Birds of Western Colorado Plateau and Mesa Country" (Righter et al. 2004) and the "Colorado Breeding Bird Atlas" (Kingery 1998) were reviewed to determine the likelihood for species occurrence within the project area. Bird identification and taxonomic nomenclature are in accordance with that applied by the Colorado Breeding Bird Atlas Project (Kingery 1998). The determination of the presence/absence of suitable habitat for Threatened, Endangered, and "Sensitive Species" (TESS) plants was based on previous WWE observations of typical habitat occupied by BLM or USFS sensitive plants, the Colorado Natural Heritage Program (CNHP) Rare Plant Field Guide (Spackman et al. 1997), and locations of species documented in the CNHP statewide database. 3.2 Survey Methods A preliminary review of the project area, using aerial photography maps, was conducted to familiarize personnel with vegetation types and terrain and as an aid to help determine the likelihood of the presence of threatened, endangered, or sensitive wildlife and plant species. Field data, including general project location, boundaries, and reported features, were verified and/or recorded with the aid of a handheld global positioning system (GPS) receiver utilizing NAD83/WGS84 map datum, with all coordinate locations based on the Universal Transverse Mercator (UTM) coordinate system within Zone 12. WWE biologists conducted pedestrian surveys of the area to identify and locate wildlife species, wildlife sign (tracks, fecal droppings, and vegetation disturbance), vegetation communities, and wildlife habitats. Vegetation types were determined through field identification of plants, aerial photography, and on -the -ground assessments of plant abundance. Identification of plant species was aided by using pertinent published field guides (Whitson et al. 2004, Weber and Wittman 2001, CWMA 2007, Kershaw et al. 1998). Visual searches for raptor and other bird species nests were focused on shale cliffs, scattered juniper trees, and the riparian areas along Conn Creek within a 0.25 mile distance from WestWater Engineering Page 3 of 20 May 2009 I(7 the water treatment and storage facility. Nest searches and bird identification were aided with the use of binoculars and song recognition, where needed. Photographs were taken of the general project location, surrounding vegetation, and terrain (Cover Photo). 4.0 RESULTS OF SURVEY 4.1 TESS Plant Species Special status species of plants that may be present in the project area, and their habitats, are listed in Tables 1 and 2. There are two categories for TESS plant listing, 1) Federal Threatened, Endangered and Candidate Species (2 species) and 2) BLM Sensitive Species (3 species). Nomenclature and habitat descriptions are based on the CHNP literature (Spackman et al. 1997). Table 1. Potential Federally -listed Threatened, Endangered, and Candidate plant species Scientific Name Common Name Status* Habitat Preference Phacelia scopulina var. submutica DeBeque phacelia C This plant grows only in Garfield and Mesa counties within the Piceance Basin in western Colorado. The plant is restricted to the barren, dark gray and brown, clay soils of the Atwell Gulch and Shire members of the Eocene and Paleocene Wasatch geological formation. Elevation; 4,700 to 6,200 feet Sclerocactus glaucus Colorado hookless cactus T Endemic to western Colorado; generally found on coarse soils derived from cobble and gravel river and stream terrace deposits, or rocky surfaces on mesa slopes at 4,400 to 6,200 feet in elevation. * E= Federal Endangered, T= Federal Threatened, C= Federal Candidate Table 2.

The project site and surrounding area potentially affected by the facility (silt loading) drain into Conn Creek and from there into the section of the Colorado River that is designated critical habitat for the Federally -endangered Colorado pikeminnow and razorback sucker (Maddux et aI. 1993). 4.3 State Listed Threatened, Endangered Special Concern Wildlife Species WWE biologists determined that one state -Listed threatened, endangered, or special concern species may occur within or be affected by the project and is listed in Table 3 (CDOW 2008b). Table 3. Potential State -listed Threatened, Endangered and Special Concern wildlife species Scientific Name Common Name State Status Habitat Preference Oncorhynchus clarki pleuriticus Colorado River cutthroat trout SC Perennial mountain streams on the Roan Plateau in drainages of Parachute and Roan Creeks. E= State Endangered, T= State Threatened, SC = Species of Concern The project area is not known to CDOW to be habitat for Colorado River cutthroat trout. There are no fisheries inventories of Conn Creek documented by CDOW or any other agency (Elrnblad 2008 pers. comm.). 4.4 Birds of Conservation Concern (BOCC) 4.4.1 Raptors Several raptor (birds of prey) species nest, reside, forage, or pass through the general area of the water treatment and storage facility. Raptor species that are common to the area include Golden Eagle, Bald Eagle, Red-tailed Hawk, American Kestrel, Cooper's Hawk, Sharp -shinned Hawk, Northern Harrier, Peregrine Falcon, Long-eared Owl, and Great Horned Owl. The riparian corridors and shale cliffs existing in the project area are of sufficient height and density for tree and cliff nesting raptors. Raptor species that are Iisted as BOCC within the Piceance Basin, which may occur in the project area, are Iisted in Table 4. In addition to the BOCC list, eight other species of raptors that could potentially be found nesting in the project area are also listed in Table 4. WestWater Engineering Page 5 of 20 May 2009 Table 4.

Swainson's Hawk Buteo swainsoni Y • Typically, arid grassland, desert, agricultural areas, shrublands and riparian forests. Nests in trees in or near open areas. Golden Eagle Aquila chrysaetos Y • Grasslands, shrublands, agricultural areas, pif on - juniper woodlands, and ponderosa forests. Prefers nest sites on cliffs and sometimes in trees in rugged areas. American Kestrel Falco sparverius N • Coniferous and deciduous forests and open terrain with suitable perches. Nests in cavities in trees, cliffs and buildings. Peregrine Falcon Falco peregrines Y • Pifon juniper woodlands and coniferous and riparian forest near cliffs. Nests on ledges of high cliffs away from human disturbance. Prairie Falcon Falco mexicanus Y • Grasslands, shrublands, and alpine tundra. Nests on cliffs or bluffs in open areas. Great Horned Owl Bubo virginianus N • Occupies diverse habitats including riparian, deciduous and coniferous forests with adjacent open terrain for hunting. Northern Saw- whet Owl Aegolius acadicus N • Mountain and foothills forest and canyon country. Significant use of pifion-juniper woodland and Douglas -fir. Long-eared Owl Asio otos N • Occupies mixed shrublands. Nests and roost in sites in dense cottonwoods, willows, scrub oak, junipers and dense forest of mixed conifers and aspens. Bald Eagle g Haliaeetus leucocephalus Y • Generally nest near larger bodies of water that support fish populations. Nests in large trees and cliffs. One raptor nest was observed in a cottonwood tree in the adjacent riparian area northeast of the water treatment and storage facility (Figure 1, Table 5, Photo 1). The nest was unoccupied with an unknown activity status and is likely an old accipiter nest. No known Bald Eagle nest sites are located within the project area. CDOW records (NDIS 2007) indicate Bald Eagle winter range is along the Roan and Conn Creek basins, south of the water treatment and storage facility (Figure 1). Bald Eagles often feed on the carcasses of mule deer, which have died due to winter stress or highway road -kills.

Lewis's Woodpecker Melanerpes lewis • Riparian habitats, nests in old decadent cottonwoods • Uncommon; individual bird observed by WWE biologist in May, 2005 on Clear Creek. No BOCC were observed during the survey. Suitable habitats for the species listed in Table 6 were observed in the area of the project. 4.4.3 Greater Sage -Grouse The Greater Sage -Grouse is recognized by the BLM and CDOW as a species of special concern. Greater Sage -Grouse occupy the sagebrush shrublands on the divide between the Parachute Creek and Roan Creek drainages. They require Large, continuous areas of sagebrush habitat on flat gently rolling terrain with vegetation dominated by sagebrush (Artemesia tridentata var. vaseyana) and, generally, lacking an overstory of mountain shrub or woodland species. Recent research by the CDOW reveals that approximately 80 percent of the females nest within a 4 -mile radius of the lek on which they were bred (Colorado Greater Sage -Grouse Conservation Plan 2008). WestWater Engineering Page 9 of 20 May 2009 The OXY Water Treatment and Storage Facility is located outside the normal habitat for Greater Sage -Grouse, but it falls within the 4 -mile radius from an active lek (Chimney Rock) and a historical lek (Long Point). No sage -grouse sign was observed during the surveys. It is unlikely that sage -grouse will occur on the project site due to the limited amount of sagebrush and the existing disturbance. Active and inactive lek sites can be seen in Figure 1. 4.5 Terrestrial Species 4.5.1 American Elk and Mule Deer The water treatment and storage facility lies within CDOW, Game Management Unit (GMU) 31. The project area is situated within mule deer and American elk overall range. It is also included in mule deer winter range and elk winter range. The water treatment and storage facility lies within an elk winter concentration area as mapped by CDOW "NDIS" (Figure 2). During the survey, deer droppings and fresh tracks were observed throughout the project area. Elk and mule deer utilize the winter range extensively on the Roan Creek drainage, following the snow line to higher elevations in the spring. Mule deer rely on the existing sagebrush and shrubs for their primary food source, while elk rely primarily on available grasses for food. Areas of pinon juniper woodlands and scattered oakbrush and serviceberry copses provide necessary forage and production areas as well as escape, thermal, and loafing cover for deer and elk, particularly during the summer period. 4.5.2 Black Bear and Mountain Lion CDOW "NDIS" mapping shows the water treatment and storage facility to be within overall range for black bear and mountain lion. It also lies within a black bear fall concentration area (Figure 1), which follows Conn Creek. Black bear are a common resident mammal on the Roan Plateau. Black bears are omnivorous and the diet depends largely on what kinds of food are seasonally available, although their mainstay is vegetation. In spring, emerging grasses and succulent forbs are favored. In summer and early fall, bears take advantage of a variety of berries and other fruits. In late fall, preferences are for berries and mast (acorns), where available. When the opportunity is present, black bears eat a diversity of insects, including beetle larvae and social insects (ants, wasps, bees, termites, etc.), and they kill a variety of mammals, including rodents, rabbits, and young or unwary ungulates. The Roan Plateau provides important habitat to black bear during the late spring, summer, and fall months with its abundance of berry and mast producing plants including serviceberry, chokecherry, and Gambel oak. Black bear are in hibernation from mid-November through May. The project area is not mapped by CDOW as a potential black bear conflict area. Mountain lion typically follow migrating deer herds in search of deer as the primary food source. Mountain lion have large territories and are highly mobile as they search for food or new territories. Mountain lion prefer to hunt in rocky terrain near woodland habitats. These habitat conditions occur within the project area. Mountain lion could travel through and hunt in the project area year-round. The project area is not mapped by CDOW as a potential mountain lion conflict area.

Other common small mammal species (small game, furbearers, non -game) that may be present on the project site include valley pocket gopher (Thomomys bottae), cottontail rabbit (Sylvilagus spp.), white-tailed jackrabbit (Lepus townsendii), and least chipmunk (Tamias minimus). Species of bats from the genera Myotis may be present in the woodlands including two BLM sensitive species, Myotis yumanensis and Myotis thysanodes. 4.5.4 Other Bird Species The proposed project lies within overall range for wild turkey (Merriam's - Meleagris gallopavo merriami). Wild turkeys are commonly observed in the Roan Creek drainage area. The project areas' shrublands, woodlands, and understory grasses provide nesting and foraging habitats for various other migratory and non -migratory bird species, depending on the season of the year. Bird species observed during the surveys include American Crow (Corvus brachyrhynchos), Common Raven (Corvus corax), Northern Flicker (Colaptes auratus), Townsend's Solitaire (Myadestes townsedi), Mountain Bluebird (Sialia currucoides), American Robin (Turdus migratorius), Dark -eyed Junco (Junco hyemalis), Black -billed Magpie (Pica pica), Spotted Towhee (Pipilo maculatus), and Song Sparrow (Melospiza melodia). Other bird species that may occur on the project site include: Brewer's Sparrow (Spizella breweri), Vesper Sparrow (Pooecetes gramineus), Tree Swallows (Tachycineta thalassina), Cliff Swallows (Petrochelidon pyrrhonota), Turkey Vulture (Cathartes aura), and Green -tailed Towhee (Pipilo chlorurus). Two cavity nest holes were observed in the cottonwood trees (Photos 2 and 3), and one small nest was observed in a Gambel's oak near the southern end of the project area (Photo 4). IAD Photo 3. Cavity nest hole #2 WestWater Engineering Page 12 of 20 May 2009 Photo 4. Small nest observed in a Gambei's oak on southern end of project area. 4.5.5 Reptiles Plateau striped whiptail (Cnemidophorus velox), sagebrush lizard (Sceloporus graciousus), short - horned lizard (Phrynosoma hernandesi), collared lizard (Crotaphytus collar's), Western terrestrial garter snake (Thamnophis elegans), Racer (Coluber constrictor), bull snake (Pituophis catenifer), and western rattlesnake (Crotalus viridis) are reptiles potentially occurring in the project area. 4.6 Aquatic Species 4.6.1 Amphibians Two BLM sensitive species, the Northern Leopard frog (Rana pipiens) and the Great Basin spadefoot (Spea intermontana), along with the Tiger salamander (Ambystoma tigrinum) and Chorus frog (Pseudacris triseriata), may occur near the project in suitable ponds and in Conn Creek. 4.6.2 Fish Conn Creek is the only intermittent drainage within the project area. There are no data available from CDOW or other sources on fish populations for Conn Creek (Elrnblad 2008 pers. comm.). In the immediate vicinity of the project location, water was not flowing in Conn Creek during the survey. 5.0 AFFECTS TO WILDLIFE 5.1 Wildlife Impact Assessment The OXY Water Treatment and Storage Facility will affect site-specific native vegetation and wildlife habitat adjacent to the project site. Due to its relative small size and because the area within and around the water treatment and storage facility is already heavily developed, the project will minimally affect wildlife. The project will contribute to the overall cumulative impacts to the wildlife populations of the Roan PIateau that are experiencing gradual habitat loss, ' fragmentation, alteration, and displacement through increased development. WestWater Engineering Page 13 of 20 May 2009 ( 5.1.1 Terrestrial Species 5.1.1.1 Elk and Mule Deer Potential affects include the temporary loss of a small amount of elk and mule deer winter ranges. Human presence and activities during the project may create a direct disturbance for elk and deer populations within and immediately adjacent to the project area, although no hunting is authorized on properties controlled by OXY. 5.1.1.2 Birds Greater Sage -Grouse: Sage -grouse are highly dependent on sagebrush dominated habitats on the Roan Plateau. The quality and quantity of this habitat type dictates its suitability for sage - grouse. Disturbance to sagebrush shrublands that reduces the availability and suitability of presently occupied habitat would affect this species. However, no suitable sagebrush habitat is located within or near the proposed project. The nearest lek to the water treatment and storage facility is Long Point Lek (historical lek site, approximately 1.25 miles away), while the nearest active lek (Chimney Rock) is located approximately 2.25 from the project site (Figure 1). There is a large, steep canyon wall between both lek sites and the project site. Passerine Species: The affects to foraging and nesting habitat to a small number of bird species is expected to be minimal. The project will require the removal of vegetation for constructing and operating the facility. Affects to local bird species would be more significant should vegetation clearing occur during the breeding/nesting season. Raptors: One nest was observed within 0.25 miles of the project site. The activity status of this nest is currently unknown by CDOW definitions, as the nest has been observed for only one season. Raptor nesting within 0.25 miles of the water treatment and storage facility could potentially be indirectly affected by disturbance associated with the water treatment and storage facility, including equipment and human presence. Nest sites that are in direct -line of site of construction activities have the most potential for being adversely affected. Effects of disturbance to nest sites are often mitigated when Vegetation or terrain features are present to hide the nest from direct -line of sight. 5.1.1.3 Black Bear and Mountain Lion Due to the large home range of both black bear and mountain lions, and because of the extensive amount of available habitat for these species, no significant affects from this project for these species are expected. 5.1.1.4 Small Mammals The amount of available habitat for small mammals, including bats, should not be affected significantly by the water treatment and storage facility. 5.1.1.5 Reptiles The amount of available habitat for reptiles should not be impacted significantly by the water treatment and storage facility. Disturbance will occur primarily within an existing disturbed site, which is not expected to affect reptile populations. WestWater Engineering Page 14 of 20 May 2009 5.1.2 Aquatic Species 5.1.2.1 Amphibians Downstream individuals would be most susceptible in the event contaminates were introduced to surface water during construction or operational activities. The amount of available habitat for amphibians should not be affected significantly by the water treatment and storage facility. Disturbance will occur primarily within an existing disturbed site, which is not expected to affect amphibian populations. 5.1.2.2 Endangered Fish The Colorado pikeminnow and the razorback sucker are both federally -listed fish species that occur in the Colorado River. Potential impacts from the water treatment and storage facility include: water use, sedimentation of tributaries to the Colorado River, and spills of chemicals and fuels from equipment. It is not likely that endangered fish will be affected by this project, due to the distance from the Colorado River and the project size. Appropriate application of stormwater Best Management Practices (BMPs) and Spill Prevention Counter Control (SPCC) measures will also help reduce any potential impacts to aquatic species. 6.0 AFFECTS TO TESS PLANT SPECIES No TESS plants or their habitats were found during surveys, and therefore no affects on TESS plants are expected. 7.0 MITIGATION RECOMMENDATIONS The following recommendations for mitigation are presented for maintenance and improvement of wildlife habitat, quality, and prevention of human -caused impacts to resources. 7.1 Maintenance and Restoration of Habitat Sagebrush communities in the Piceance Basin have declined over the years and continue to do so as a result of development and loss of habitat. Noxious weeds and invasive plant species have now invaded many habitats due to construction and ground clearing of native vegetation. Woodlands, sagebrush and native grasses are key food sources for elk and mule and provide nesting and foraging habitat for a variety of migratory birds and small mammals. Reclamation plans should include efforts to restore these vegetation communities, particularly the sagebrush community for sage -obligate species. Reclamation recommendations include the following: 1. Seeding of native Wyoming and big basin sagebrush should be added to the re -vegetation plan. Local, ecologically adapted sagebrush seed from the existing sagebrush vegetation near the project area should be used in reclamation. 2. Ongoing control of noxious and invasive weeds is recommended as an additional method to maintain native vegetation communities and favorable wildlife habitats. An WestWater Engineering Page 15 of 20 May 2009 "Integrated Vegetation and Weed Management Plan" is provided for this project in a separate report. 3. Mitigation for wetland impacts will be provided in accordance with Army Corp of Engineers standards. 7.2 Planning for Sensitive Time Periods and Areas 7.2.1 Mule Deer and Elk Disturbance associated with construction equipment and personnel may cause elk and mule deer to select habitats in more secluded areas away from the water treatment and storage facility. Any construction and/or operational activities during the winter months will impact deer and elk winter range as mapped by the CDOW "NDIS". According to the Colorado Oil and Gas Conservation Commission's amended rules, effective April 1, 2009, elk winter range is excluded from the rules as sensitive wildlife habitat. Deer critical winter range and deer severe winter range are included in the new 2009 rules, neither of which are located within the project area (COGCC 2009). 7.2.2 Migratory Birds In order to comply with the Migratory Bird Treaty Act by showing a good faith effort to reduce potential impacts on nesting birds, brush/tree clearing should take place outside of the nesting seasons. Nesting season is generally considered between May 15 and July 31 in this area for most species. June 1 to July 15 is the peak period when most incubation and brood rearing takes place. If brush/tree clearing can occur prior to May 1, most affected birds will relocate to alternate nesting sites. After mid-to-late July, most fledging has occurred and brush/tree clearing impacts would be minimized. Pinyon Jays are an exception to typical nesting periods in this area and are known as an early nester. Records show nests with eggs as early as March 23. Often young birds have fledged by May 15. Because Pinyon Jay habitat makes up a lesser amount of the project site, the pre -May 1 vegetation clearing recommendation is acceptable and adequate to avoid destruction of active migratory bird nests. 7.2.3 Greater Sage -Grouse In order to reduce the likelihood that sage -grouse populations decline near the project area, effective natural gas pre -development planning and post -development practices offer the best prospect for mitigating adverse affects to sage -grouse populations. Planning development with projects engineered to avoid, minimize, and mitigate affects of natural gas development are approaches that result in the most favorable mitigation outcomes. No affects to sage -grouse are expected to occur as a result of the facility construction, operation, or maintenance. No specific planning is recommended in regards for Greater Sage -grouse. WestWater Engineering Page 16 of 20 May 2009 7.2.4 Raptors Activities associated with the water treatment and storage facility have the potential to impact raptor populations. In order to reduce the potential affects to nesting raptors, it will be important that the project proponent schedule construction activities such that they do not interfere with breeding, nesting, and brood rearing activities. CDOW's (Craig 2002 and Klute 2008) recommended raptor nest site avoidance standards for the species observed in this survey are summarized below (Table 7). If the project cannot be completed prior to, or after, the next nesting season, known nest sites should be re -inventoried by qualified biologists. If any birds are found behaving in a manner consistent with nesting, every effort should be made to apply the timing limitation and buffer distance stipulations. Table 7.

Keep activity to a minimum during breeding season. 7.3 Other Mitigation Practices 7.3.1 Erosion Efforts to control soil erosion within the project area should be implemented. Disturbed soils within the project area are susceptible to erosion and downstream water quality could be negatively affected by increased soil erosion. In addition to stormwater management around the project site, other current factors (noxious weeds, livestock grazing, other natural gas development) affecting soil erosion should be managed and remedial measures implemented. Prior to any construction which involves potential stream crossings, appropriate consultation with the U.S. Army Corps of Engineers (ACOE) is recommended. To protect the integrity of the stream ecosystems and the associated riparian habitat within the project area, precautions should be taken when crossing or intersecting the drainages identified. Implementation of a storm water management plan and standard best management practices, including adequate barriers and filtration methods, should be used to prevent and reduce soil from eroding into streams and riparian areas. This may include the installation of check dams along small ephemeral drainages and vegetation restoration. WestWater Engineering Page 17 of 20 May 2009 7.3.2 Black Bears Black bears will likely move through the general project area and could be attracted to human - related food sources (garbage, pet foods and barbeque grills). In order to prevent human injury and/or the un -wanted removal, injury, or destruction of bears, it is recommended that food and garbage storage and removal be done in a timely and secure manner so as to not habituate bears to the human activities of the project.

OXY has a Noxious Weed Management Plan in place; this is intended to augment the existing plan. OXY is proposing to develop a water treatment and storage facility, which lies approximately 12 miles north of DeBeque, Colorado in Section 29, Township 6 South, Range 97 West (Figure 1). The water treatment and storage facility is within Garfield County, Colorado and is located on private land. The facility is approximately 17 acres in size, and is located adjacent to Conn Creek. Access to the project site is currently available via County Road 204 (Roan Creek Road), County Road 213 (Conn Creek Road), and a private road. The primary use of the site and surrounding area is rangeland, pasture, wildlife habitat, and natural gas extraction/development. The general project area is currently undergoing rapid natural gas development including drilling of wells, construction of pipelines, compressors, and access roads. 1.2 General Survey Information Mapped soil types, as published by the Natural Resources Conservation Service (MRCS), U.S. Department of Agriculture (USDA), were reviewed to determine the soil types and vegetation characteristics of the water treatment and storage facility and surrounding area (NRCS 2009). Field inspection of the project area was conducted by WWE biologists on April 6, 2009. WWE biologists surveyed the area in and around the water treatment and storage facility to identify vegetation communities and to search for, identify, and map noxious weed species. Vegetation types were determined through field identification of plants, aerial photography, and on -the -ground assessment of plant abundance visible during the survey. Identification of plant species was aided by using pertinent published field guides (Whitson et al. 2001, CWMA 2007, Kershaw et al. 1998, Weber and Wittmann 2001). Photographs were taken of the general project location, vegetation, terrain, and other specific biological findings. Locations of weeds and other features included in this report were recorded with the aid of a handheld global positioning system (GPS) receiver using NAD83/WGS84 map datum, with all coordinate locations based on the Universal Transverse Mercator (UTM) coordinate system in Zone 12S. 2.0 LANDSCAPE SETTING 2.1 Vegetation Communities Vegetation communities around the water treatment and storage facility are a mixture of widely scattered pinon juniper, sagebrush dominated shrublands in the valley floor, and mountain shrub on the adjacent steep slopes. Agricultural meadows are present on private lands only, about 0.1 WestWater Engineering Page 1 of 14 May 2009 miles south of the project location. Pinon juniper woodlands are dominated by Utah juniper (Juniperus osteosperma) and occasional pinon pine (Pinus edulis) and are mixed with Wyoming sagebrush (Artemisia tridentata wyomingensis), forbs, and grasses. The water treatment and storage facility boundaries are immediately adjacent to Conn Creek, and therefore, riparian communities are present in the project area. Vegetation along the creek consists of cottonwood (Populus spp.), greasewood (Sarcobatus vermiculatus), Rabbitbrush (Chrysothamnus nauseosus),.willows (Salix spp), alder (Alnus spp), Gambel oak (Quercus gambelii), box -elder (Negundo aceroides) and basin big sagebrush (Artemisia tridentata tridentata). The shrublands within the project area are characterized by basin big sagebrush, greasewood, and green rabbitbrush (Chrysothamnus viscidorus). Non-native downy brome (Bromus tectorum) and annual wheatgrass (Eremopyrum triticeum) dominate the understory for this shrubland community. The adjacent mountain shrub vegetation consists primarily of serviceberry (Amelanchier alntfolia), Gambel's oak, and Wyoming big sagebrush with an understory of grasses and forbs. Bare ground is also present throughout much of the site due to impacts from development. The climate for the Piceance Basin is considered semi -arid with a wide range of temperatures and precipitation. The closest weather station is at the Altenbern Ranch 011 Roan Creek, which has provided reliable records to the National Oceanic and Atmospheric Administration (NOAA) since 1948. The average annual precipitation at the ranch is 16.41 inches, with a record low temperature of minus 38 degrees Fahrenheit and a record high temperature of 104 degrees Fahrenheit (NOAA website: www.noaa.gov). The average annual precipitation at the upper elevations in the project area should equal, and likely exceed, that observed along Roan Creek. 2.2 Soils Soil types include loams and sandy to gravelly loams that overlay broken shale derived from the Green River Formation. This formation is visible in the sheer canyons of Roan and Parachute Creek and the Roan Cliffs overlooking the towns of Rifle, Parachute, and DeBeque, Colorado. In many areas, soil profiles are shallow, with only 12-24 inches of soil overlying deep, broken shale deposits. Soil types and the vegetation supported vary with elevation and slope aspect. Mapped soil types, as published by the Natural Resources Conservation Service (NRCS), U.S. Department of Agriculture (USDA), were reviewed to determine the soil types and vegetation characteristics of the project site and surrounding property (NRCS 2008). Two soil types are found in the project area and include the following: 1. Happle very channery sandy loam with 3 to 12 percent slopes. 2. Happle-Rock outcrop association, with 25 to 65 percent slopes. 23 Terrain The terrain varies from flat to moderately steep hillsides with elevations ranging from about 5,900 ft to about 6,200 ft. The water treatment and storage facility lies adjacent to Conn Creek, the section of which is classified as an intermittent stream. No water was flowing in the creek at the time of the survey. Natural gas exploration and development is resulting in landscape/watershed scale habitat fragmentation. The physical loss of habitat is due primarily to the increase in roads, well pads, WestWater Engineering Page 2 of 14 May 2009 pipelines, compressor stations, and other ancillary facilities required to produce and transport natural gas. Additionally these activities contribute to the introduction and/or spread of invasive species. Generally the undisturbed area retains good vegetation cover, including native grasses such as Sandberg bluegrass (Poa sangbergii), Indian ricegrass (Achnatherum hymenoides), bottlebrush squirreltail (Elymus elmoides), galleta (Haiaria jamesii), and needle -and -thread grass (Hesperostipa comata), introduced and invasive grasses including downy brome, annual wheatgrass and crested wheatgrass (Agropyron cristatum), as well as forbs and shrubs including sagebrush and greasewood. 3.0 NOXIOUS WEEDS 3.1 Introduction to Noxious Weeds Noxious weeds are plants that are aggressive competitors when non-native to an area. Most have come from Europe or Asia, either accidentally or as ornamentals that have escaped. Once established in a new environment, they tend to spread quickly because the insects, diseases, and animals that normally control them are absent. Noxious weeds are spread by man, animals, water, and wind. Prime locations for the establishment of noxious weeds include roadsides, construction sites, areas that are overused by animals or humans, wetlands, and riparian corridors. Subsequent to soil disturbances, vegetation communities can be susceptible to infestations of invasive or exotic weed species. Vegetation removal and soil disturbance during construction can create optimal conditions for the establishment of invasive, non-native species. Construction equipment traveling from weed -infested areas into weed -free areas could disperse noxious or invasive weed seeds and propagates, resulting in the establishment of these weeds in previously weed -free areas. The Colorado Noxious Weed Act (State of Colorado 2005) requires local governing bodies to develop noxious weed management plans. Both the State of Colorado and Garfield County maintain a list of plants that are considered to be noxious weeds. The State of Colorado noxious weed list includes three categories. List A species must be eradicated whenever detected. List B species include weeds whose spread should be halted. List C species are widespread, but the State will assist local jurisdictions which choose to manage those weeds. The Garfield County Weed Advisory Board has compiled a list of 21 plants from the State list considered to be noxious weeds within the county (see Appendix A). Three of those weed species were found in, or near, the project area. The Garfield County Weed Advisory Board has duties to: 1. Develop a noxious weed list, 2. Develop a weed management plan for designated noxious weeds, and 3. Recommend to the Board of County Commissioners that identified landowners submit an integrated weed management plan for their properties. 3.2 Observations Six Colorado State listed weed species are found in the project area, three of which are listed by Garfield County (Table 1 and Appendix A). Colorado State B listed weeds (three) observed in the project area were musk thistle (Carduus nutans), bull thistle (Cirsium vulgare), and WestWater Engineering Page 3 of 14 May 2009 houndstongue (Cynoglossum officinale). Colorado State C listed weeds (three) observed in the project area were common burdock (Arctium minus), common mullein (Verbascum Thapsus), and downy brome (Bromus tectorum). Of these State listed weeds, houndstongue, common burdock, and musk thistle are listed by Garfield County. Heaviest infestations of Garfield County listed noxious weeds were found both along the banks of Conn Creek, adjacent to the project site, and along a natural gas pipeline right-of-way which runs north/south through the project area (Figure 1). Additional invasive plants were found in the project are that are not listed by the State of Colorado or Garfield County but may be considered nuisance weeds. These plants can negate revegetation efforts and cause losses due to decreased seeding success and associated costs. The presence of these plants creates increased competition for resources by desirable seeded and native young plants. Plants in this category observed in the project area include Russian thistle (Salso spp.) and annual wheatgrass (Eremopyrum triticeum). These species were noted in vegetation descriptions. The locations of the listed weeds are displayed in Figure 1, and listed in Table 1 and Appendix B. Table 1.

Care must be taken to prevent damage to desirable plant species during treatments to prevent further infestations by other pioneer invaders. Weed management is best achieved through a variety of methods over a long period of time including, inventory (surveys), direct treatments, prevention through best management practices, monitoring of treatment efficacy, and subsequent detection efforts. Weed management is often reserved to "control" of existing species and prevention of further infestations (existing and novel species) rather than eradication. After successful and effective management, decreases in infestation size and density can be expected, and after several years of successful management practices, eradication is sometimes possible. 3.3 Prevention and Assessment of Noxious Weed Infestations Weed management is costly and heavy infestations may exceed the economic threshold for practical treatment. Prevention is especially valuable in the case of noxious weed management. Several simple practices should be employed to prevent most weed infestations. The following practices should be adopted for any activity to reduce the costs of noxious weed control through prevention. The practices include: • Prior to delivery to the site, equipment should be thoroughly cleaned of soils remaining from previous construction sites which may be contaminated with noxious weeds; and • If working in sites with weed -seed contaminated soil, equipment should be cleaned of potentially seed -bearing soils and vegetative debris at the infested area prior to moving to uncontaminated terrain. • All maintenance vehicles should be regularly cleaned of soil. • Avoid driving vehicles through areas where weed infestations exist. Assessment of the existence and extent of noxious weeds for an area is essential for the development of an integrated management plan. This report provides an initial assessment of the occurrence of noxious weeds for the project area. In order to continue effective management of noxious weeds, further inventory and analysis is necessary to 1) determine the effectiveness of the past treatment strategies 2) modify if necessary the treatment plan and 3) detect early any infestations of new species or location and thus more economical treatments of such. 3.3 Treatment and Control of Noxious Weed Infestations Invasive and noxious weeds commonly occur along ditches, creek corridors and adjacent drainages (especially in riparian areas), abandoned fields, and disturbed areas such as well pads, pipeline routes, and roadsides. Control methods for the six noxious weed species found in the project area are described in Table 2. Included in Table 2 are weed life cycle type and recommended control methods for each weed species. WestWater Engineering Page 6 of 14 May 2009 Table 2.

Each of the weed species found on the project site are either biennials or annuals, and the treatment strategies for these plant types are summarized in Table 3. It should be noted that herbicides should not always be the first treatment of choice when other methods can be effectively employed. Some weeds, particularly annuals and biennials, can develop resistance to herbicides. The ability to quickly develop immunity to herbicides, especially when they are used incorrectly, makes it imperative to use the proper chemicals at the correct time in the specified concentration according to the product label. Most misuse is centered on excessive application, either in frequency or concentration. This results in mostly top kill and resistant phenotypes. WestWater Engineering Page 7 of 14 May 2009 Table 3. Treatment Strategies for Annual and Biennial Noxious Weeds Target: Prevent Seed Production 1. Hand grub (pull), hoe, till, cultivate in rosette stage and before flowering or seed maturity. If seeds develop, cut and bag seed heads. 2. Cut roots with a spade just below soil level. 3. Treat with herbicide in rosette or bolting stage, before flowering. 4. Mow biennials after bolting stage, before seed set. Mowing annuals will not prevent flowering but can reduce total seed production. (Sirota 2004) 3.5 Life Cycle and Management Calendars Best results in the control of certain specific noxious weeds can be achieved by following the recommended timetable presented in Table 4.

Regulations may require a Colorado licensed applicator. An applicator has the full range of knowledge, skills, equipment, and experience desired when dealing with tough noxious weeds. Reclamation farming services using multiple seed bin range drills and specialized related equipment is available and should be used for reclamation seeding projects. Common chemical and trade names may be used in this report. The use of trade names is for clarity by the reader. Inclusion of a trade name does not imply endorsement of that particular brand of herbicide and exclusion does not imply non -approval. Certified commercial applicators will decide which herbicide to use and at what concentration according to label directions. Landowners using unrestricted products must obey all label warnings, cautions, and application concentrations. The author of this report is not responsible for inappropriate herbicide use by readers. 3.7 Best Management Practices — Noxious Weeds Construction: The following practices should be adopted for any construction project to reduce the costs of noxious weed control and aid in prevention efforts. The practices include: • top soil, where present, should be segregated from deeper soils and replaced as top soil on the final grade, a process known as live topsoil handling; • wetland vegetation, if encountered, should be live handled like sod, temporarily watered if necessary, and placed over excavated sub -soil relative to the position from which the wetland sod was removed; WestWater Engineering Page 9 of 14 May 2009 • cut-off collars should be placed on all wetland and stream crossings to prevent back washing or draining of important aquatic resources; • in all cases, temporary disturbance should be kept to an absolute minimum; • equipment and materials handling should be done on established sites to reduce area and extent of soil compaction; • disturbances should be immediately reseeded with the recommended mix in the re- vegetation section; • topsoil stockpiles should be seeded with non-invasive sterile hybrid grasses, if stored longer than one growing season; • prior to delivery to the site, equipment should be cleaned of soils remaining from previous construction sites which may be contaminated with noxious weeds; and • if working in sites with weed-seed contaminated soil, equipment should be cleaned of potentially seed-bearing soils and vegetative debris prior to moving to uncontaminated terrain. In areas with slope greater than 3 percent, imprinting of the seed bed is recommended. Imprinting can be in the form of dozer tracks or furrows perpendicular to the direction of slope. When utilizing hydro-seeding followed by 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 should 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. Herbicides: Annual and biennial weeds are best controlled at the pre-bud stage after germination or in the spring of the second year. The species identified in the survey are susceptible to commercially available herbicides. Selective herbicides are recommended to minimize damage to desirable grass. Herbicide use in the riparian zone should be restricted to formulations that are approved for such use. Non-selective aquatic glyphosate formulations (e.g., Rodeo®) can be used in riparian areas with little danger to the ground or surface water, but desired grasses, forbs, shrubs and trees are susceptible to damage by direct contact. Professionals or landowners using herbicides must use the concentration specified on the label of the container in hand. Herbicides generally do not work better at higher concentrations. Most herbicide failures observed by WWE are related to incomplete control caused by high concentrations killing top growth before the active ingredient can be transported to the roots through the nutrient translocation process. Most herbicide applications should use a surfactant if directed on the herbicide label or other adjuvants as called for on the herbicide label. Grazing: Grazing should be deferred, in reclaimed areas, until the desired grass species are established. Mechanical: Many of the current infestations occur on disturbed surfaces that could be easily accessed and are relatively void of vegetation. These areas are ideal for mechanical control with a hand tool (shovel etc.) during infestation stages while numbers are relatively low and visibility is good. Mechanical methods are more difficult in riparian areas where heavy vegetation limits access WestWater Engineering Page 10 of 14 May 2009 ( and visibility. An aquatic labeled herbicide for near water use will need to be used to treat common burdock at the project site, because of its prevalence near perennial Conn Creek, Bio -control Agents: Alternative Methods: An alternative method, particularly where there is poor or destroyed topsoil, is the application of vesicular-arbuscular mycorrhizal fungi typically referred to as AMF. These fungi, mostly of the genus Glornus, are symbiotic with about 80 percent of all vegetation. Endo-mycorrhizal fungi are associated mostly with grasses and forbs and could be helpful when reclaiming this project. In symbiosis, the fungi increase water and nutrient transfer capacity of the host root system by as much as several orders of magnitude (Barrow and McCaslin 1995). Over-the-counter commercial products, which are better adapted to coating seeds when re- seeding and treating roots of live seedling trees and shrubs at time of planting, come in powder form and are available from many different sources. Some also come in granular form to be spread with seed from a broadcast spreader. The best AMF products should contain more than one species. All Colorado State Forest Salida District tree and shrub plantings include the application of AMF. According to District Forester Crystal Tischler, "AMF is worth it" (Tischler 2006). Most, if not all, Colorado Department of Transportation re-vegetation/reseeding projects now require use of AMF and BioSol, a certified by-product of the penicillin manufacturing process composed primarily of mycelium. Compacted soils respond well to fossilized humic substances and by- products called humates. These humates, including humic and fulvic acids and humin were formed from pre -historic plant and animal deposits and work especially well on compacted soils when applied as directed. Due to the investment of time necessary and occurrence of sensitive native thistle species in the area, biological insect control is not recommended for this specific project. 4.0 REVEGETATION — RECLAMATION 4.1 Project Area The project area is comprised of arid shrubland mesas, foothill woodlands, and the floodplain of Conn Creek, a perennial stream. Successful reclamation of the project area is dependent upon soil type and texture, slope gradient and aspect, proper weed control, available water, and re - vegetation with suitable plant species. Based on the soil types, terrain, and the presence of noxious weeds in the project area, successful reclamation is most likely if a seed mix of grasses and shrubs is used. In the washes and canyon bottoms, the seed mix from Table 5 is recommended. Riparian areas are very resilient but also subject to changing water levels; seeding is not recommended for the riparian areas inside the banks of Conn Creek. This will allow control of noxious weeds while establishing vegetation in the disturbed areas. The suggested seed mix is based on BLM recommendation for the elevation and vegetation type presently occurring in the project area (BLM 2008). For best results and success, the recommended grass mixture reseeding should be done in late autumn. The reseeding rate should be doubled for broadcast application (CNI P 1998). WestWater Engineering Page 11 of 14 May 2009 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: • harrow with just enough soil moisture to create a rough surface, broadcast seed and re - harrow, 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. After desired grasses are established and control of target weed species is successful, then shrubs, forbs, and trees can be planted without concern for herbicide damage. Few native forb seeds are available commercially as cultivars. Most are collected from natural populations. Native shrubs and forbs often do not establish well from seed, particularly when mixed with grasses. Past experience has shown that stabilizing the soil with grasses, accomplishing weed control, and then coming back to plant live, containerized woody species in copses has been the most cost effective method for establishing the woody species component of the plant community. For sites where soil disturbance will be temporary, grasses should be drilled after construction activities cease and the equipment removed from the site. After two years of controlling weeds (with herbicides) and allowing the grasses to become established, forbs and woody species should be inter -seeded or hand -planted to increase the diversity and value of the reclamation plantings.

OXY is proposing to construct a water treatment facility, storage, and lay down yard located approximately 12 miles north of DeBeque, Colorado in Section 29, Township 6 South, Range 97 West. The proposed project will encompass approximately 17 acres in size and lies directly west of Conn Creek in Garfield County, Colorado. A wetlands impact assessment was performed by following the guidelines set forth by the regional supplement to the Corps of Engineers Wetland Delineation Manual: Arid West Region. On April 7, 2009 a field survey was conducted to determine the vegetation, soil, and hydrology of the project area. In order for an area to be considered a wetland, the site must include hydrologic features, hydrophytic vegetation must be dominant, and the soil must be hydric. The hydrology of the project site was evaluated based upon consultation of National Wetlands Inventory (NWI) maps and physical observation for the presence of typical wetland hydrological features. The NWI maps for the area indicate that there are no wetlands present within proximity of the project site, There also was no visual observation of inundation or soil saturation to the surface within the project boundaries. Several soil borings were made along the riparian corridor to determine if there is soil saturation within the top 12 inches. There was no saturation within the top 12" of the soil surface and given the potential capillary fringe for sandy loam to be 3.9-7.9", it is not likely that soil saturation to the surface occurs for more than 5% of the growing season. There were no other primary or secondary hydrological indicators observed during the survey. There are two vegetative communities located within the boundaries of the project site. The majority of the site is pinon-juniper woodlands, shrublands, and grasslands primarily dominated by Utah Juniper (Juniperus osteosperma), Pinon Pine (Pinus edulis), sagebrush (Artemsia tridentata), Rabbitbrush (Chrysothamnus nauseosus), Western Wheatgrass (Pascopyrum smithii), and Annual Wheatgrass (Eremopyrum triticeum). The other vegetative community is adjacent to Conn Creek along the riparian corridor and is dominated by Cottonwood (Populus balsamifera), Gambel Oak (Quercus gabelii), sagebrush, greasewood (Sarcobatus vermiculatus), Rabbitbrush, Dogwood (Cornus stolonifera), Redwool Plantain (Plantago eriopoda), and Annual Wheatgrass. Both vegetative communities also contain large areas bare ground due to disturbance caused by previous construction activities. Hydrophytic vegetation is not dominant in either of the vegetative communities, except within the banks of Conn Creek, which is out of the project boundary. The Hydric Soils list for Garfield County, Colorado was consulted for the presence of hydric soils with the project area. None of the soil map units on the project site are identified as being hydric soils or containing inclusions of hydric soils. The most current mapping from the Natural Resources Conservation Service (NRCS) Web Soil Survey shows the project site contains the following soil series: 1. Happle very channery sandy loam with 3 to 12 percent slopes. 82621V2 Road TEL 970.263.7800 Grand Junction, CO 81505 FAX 970.263.7456 www.oaconsulting.com 2. Happle-Rack outcrop association, 25 to 65 percent slopes. Additionally, soil samples indicated very little organic material within the top 12" of the surface indicative of well -drained non -hydric soil. There were no other indicators for hydric soils observed during the survey. Based on a survey and analysis of the proposed water treatment facility, storage, and lay down yard, Cordilleran did not locate any area within the project boundary that met all of the criteria to be considered a wetland. There is a presence of hydrophytic vegetation, but there were no visual indications of hydrology or presence of hydric soils. Therefore, Cordilleran has determined that the construction of the proposed project will not have any impacts to wetlands, or adversely affect water quality in any nearby waterways if appropriate best management practices are employed.

The site is approximately 5.5 miles north of the County Road 204/County Road 213 intersection. See the Figure 1 in Appendix A. The proposed facility will be constructed, operated, and reclaimed in three (3) phases. These phases include: • Construction (30 days) • Operation (25 years) • Reclamation (30 days) It is expected that the lifespan of the site will be approximately 25 years. EXISTING NETWORK This facility will be accessed from an internal private road. The subject property is accessed from CR 213. According to the Garfield County Road Inventory Report, this road is classified as Local. CR 213 consists of a two lane gravel surface roadway and has a posted speed limit of 30 mph. According to traffic counts (Garfield County October 2007) the ADT for CR 213 is 271 vehicles per day (vpd). OXY enforces a 20 MPH on the private road providing access to the proposed facility. TRAFFIC PROJECTIONS Traffic projections included in this analysis are intended to encompass all vehicular impacts to the roadway for the forecast years of 2019 and 2034. Traffic growth for this area is greatly dependent on regional economic activity and the impacts of the natural gas exploration and production industry. Based on an assessment of historic and current development activities, a conservative growth rate for all traffic of 5% was assumed. This rate was applied to the existing counts to obtain background traffic utilization encompassing the cumulative impacts for the forecast years of 2019 and 2034. This planning horizon was chosen as it corresponds with construction, operation and reclamation of the proposed office facility. This results in an expected ADT for CR 213 of 439 vpd in 2019 and 610 vpd in 2034. OXY USA WTP LP Basic Traffic Analysis . 1 May 7th, 2009 TRIP GENERATION/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 uses. To estimate trips expected for this site, information was gathered regarding the expected traffic based on production projections. The following table summarizes the expected average and maximum trips for each phase discussed previously. Table 1: Trip Generation — Water Storage Facility Phase Average Traffic/Day Maximum TrafficlDay Percent Trucks Total Traffic/Phase Phase Duration Construction 13 15 23 % 390 30 days Operation 21 24 29 % 189000 25 years Reclamation 13 18 25 % 390 30 days Note that the estimated lifespan of the site is expected to be approximately 25 years. The proposed water treatment facility will reduce the total number of trips generated by trucks transporting water off-site for disposal. The reuse of treated water will also eliminate truck traffic associated with delivery of water to OXY's drilling and production operations. The proposed storage area will allow for bulk shipment of supplies to the subject property. Current ADT's and expected trip generation are shown in Figure 2 in Appendix B. CONSTRUCTION PHASE Temporary access points will not be required during the construction phase for this project. No staging activity will be conducted within the County right-of-way. The access into this facility from CR 213 is already permitted by the Garfield County Road and Bridge Department; therefore, no additional permits are required. There will be no road closures or traffic interruptions. During the construction phase, it is not expected that a significant amount of the site traffic will be heavy truck traffic, 23% or less. These trips will be from the delivery of equipment on 18 -wheel flat bed trucks. AUXILIARY LANE ANALYSIS As defined in the Garfield County Road Inventory Report, CR 213 Functional Classification is Local, set by Colorado Department of Transportation (CDOT) and the Federal Highway Administration (FHWA). Auxiliary lanes will not be required as a result of the proposed facility. EXISTING PARCELS OXY USA WTP LP Basic Traffic Analysis 2 May 7th, 2009 Current land use on the parcel is primarily natural gas development and agricultural activity. One access exists and is permitted by Garfield County. No access to state highways or railroad crossings will be required. RECOMMENDATIONS Based on the expected trip generation rates discussed above, the increase in average daily traffic is not expected to be significant, and will not increase traffic volumes on county, state or federal road systems by 20%. The projected VPD increase on CR 213 is approximately B% Based on the results of the analysis, no mitigation is recommended for the Water Treatment/Storage Facility.

This overview was completed for Cordilleras, a division of Olsson Associates, as part of a Garfield County Building and Planning development plan application. The proposed project is a processing station that will rely on large tanks and several water purification systems, It is located along Conn Creek on private property. The project is located approximately 13 miles north of DeBeque in Section 29, T6S, R97W. The area covered by the Class 1 study includes the four legal sections surrounding the proposed processing station, and includes Sections 19-21, 28-33, T6S, R97W. The area of potential affect (APE) for the proposed project is approximately 25 acres. The investigation was performed under the stipulations of Colorado State Permit 2009-15, which expires on 2/28/10. File searches were conducted through the Colorado Office of Archaeology and Historic Preservation's (OAHP) on-line Compass database by FAC principal investigator Kae McDonald on March 11, 2009, and at the Bureau of Land Management, Grand Junction Field Office (BLM GJFO) on March 16, 2009. Effective Environment Physiographically, the project area is located along the interface of the Southern Rocky Mountains and the Colorado Plateau physiographic provinces. The Colorado Plateau is characterized by extensive horizontal, sedimentary formations, relatively high elevation, and an arid or semiarid climate (Fenneman 1931, as cited by Reed and Metcalf 1999:8). The Southern Rocky Mountains province is characterized by high and rugged ranges. The crest of the Southern Rocky Mountains forms the Continental Divide, which separates the watersheds of Pacific and Atlantic Ocean tributaries (Fenneman 1931, as cited by Reed and Metcalf 1999:7). The project area is located west of Conn Creek. Vegetation zone is pinyon juniper transitioning into montane. Elevation is approximately 6400 feet. Local bedrock geology is primarily elements of the Green River Formation (Tweto 1979). Soils are composed of warm, intermittently dry soils of the middle elevations (Reed and Metcalf 1999:14). These soils cover mesas, plateaus and lower mountain slopes, lying on top of sandstone, shale, and alluvium; depth of the soil may vary according to the topography and exposure with thinner soils along the slopes and tops of the steeper ridges, and deeper soils nearer the drainages. Deer, antelope, elk, raccoon, bears, coyotes, fox, and mountain lions, as well as numerous varieties of birds, are known to inhabit the area. The deer, antelope, and elle may have been an important part of the prehistoric diet. A variety of floral resources were probably available throughout the project area. Permanent water would have been readily available throughout the area via Conn Creek and its tributaries. Conn Creek flows south, draining into the Colorado River, which is approximately fourteen miles south of the project area. 0 0.5 1 2 1 inch equals 1 mile Mites Figure 1: OXY USA Central Water Handling Facility, Section 29, T6S, R97W, 6th PM, Garfield County (Red Pinnacle, Colo. 7.5' Quadrangle, 1962 [photoinspected 1973]). 2 Recreation, ranching, and oil and gas development are the most prominent activities in the vicinity of the project location. Paleoenvironmental models for the northern Colorado River Basin are not very complete, and tend to be contradictory if specific studies are applied to the entire region. The topography of this area of Colorado has a large effect on localized climates, and its latitudinal position is such that the effects of summer monsoon moisture vary with the strength of the monsoonal flow. This, in turn, may have affected the rate and timing of paleoclimatic events in localized areas. The key to current paleoenviromnental studies in the region is that the strength and northern limits of the summer monsoon is a critical influence in the paleoclimates (Reed and Metcalf 1999:26). Statement of Objectives General prehistoric research objectives for this area include further definition of the Paleolndlan tradition in the Northern Colorado Basin, addressing space/time systematics, settlement patterns, subsistence, technology, and origins and transitions for the Archaic, Formative, and Protohistoric eras (Reed and Metcalf 1999:170-179). Some important gaps in the understanding of the region's prehistory are also geographical (Reed and Metcalf 1999:170). Historic research objectives focus on clarifying the range, and the appropriate definition, of sites as to their historic purpose and use (Church et al. 2007; King 1984:22-28; Husband 1984). Following state and federal policies and regulations implementing the National Historic Preservation Act (Public Law 89-665) as amended, the Class 1 investigation was conducted to gather information about the number and types of cultural resources in the area surrounding the proposed water treatment facility. Culture History and Previous Work Culture History The project area is within the Northern Colorado River Basin Context (Reed and Metcalf 1999), which addresses the prehistory of the region. Northwestern Colorado historical contexts are defined in Husband (1984), as well as the recently published context for historical archaeology (Church et al, 2007). King (1984) was also consulted for discussions about engineering features, such as ditches, that might potentially be encountered in the project area. Several BLM-sponsored Class 1 overview and Class 11 sample inventories apply to this region as well. Athearn (1982) and Mehls (1982) provide details on the history of the general area, while Lutz et al. (1979), and Burgess et al. (1980) conducted sample inventories that recorded a number of prehistoric and historic resources. Excavations in the region that have contributed to a greater understanding of prehistoric activity including the Dotsero Burial (Hand and Gooding 1980), Vail Pass (Gooding 1981), the Yarmony Pit House Site (Metcalf and Black 1991), and Sisyphus Shelter (Gooding and Shields 1985). 3 Briefly, culture history reconstructions for the Northern Colorado River Basin include the Paleolndian (ca. 11,500 to 8,000 BP), the Archaic (9,00018,000 to 2,00011,500 BP), the Formative (ca. 2,000 to 700 BP, and includes Anasazi, Fremont, and Aspen Traditions), the Protohistoric (700 to 100 BP), and Historic (150 BP to Present) Eras. In the Northern Colorado River Basin, the Paleolndian era is represented by four traditions that can be distinguished primarily on the basis of projectile point styles. The earliest is the Clovis tradition, roughly dated from 13,400 to 12,500131' [cal]. Although no Clovis sites have been documented in Garfield County, both Mesa and Rio Blanco Counties boast one site each (Reed and Metcalf 1999:59). Following the Clovis tradition is the Folsom, dating from approximately 12,800 to 11, 500 BP [cal]. After the Folsom, there appears to be two traditions, each representing a distinct adaptation the Plano represents a continued focus on bison hunting on the plains, while the Foothill -Mountain complex occupied the more teer of Coer lo ado, Pitblado (1994) found ns. In a review of a fairly large sample of Paleolndian points from the so q that Foothill -Mountain projectile points (subsuming conventional types such as Pryor Stemmed, Lovell Constricted, Lusk, and Pine Springs points) are much more common in the region than point types associated with Plains -adapted groups or Great Basin groups. At least eleven sites have been recorded with as "other Paleolndian sites" (Reed and Metcalf 1999:59). Archaic -age sites are greater in number, and include a variety of site types representing a mobile lifestyle centered on hunting and the gathering of wild foods. Ground stone occurs in greater numbers after the Paleolndian Period, and probably represents an increasing reliance on vegetable foods. Higher frequencies of radiocarbon samples dating to the Late Archaic have been interpreted as an indication of increased population in the Late Archaic (Black 1986). Archaic -age sites are common throughout Garfield County (Reed and Metcalf 1999). The advent of bow -and -arrow technology, the reliance upon cultigens, and the occasional construction of masonry structures, marks the beginning of the Formative Era. Sites dating to this era are present in Garfield County, although most are found in the western half of the county (Reed and Metcalf 1999:99-104). These include one site with cultigens, three sites with Anasazi ceramics, and one site with probable Fremont ceramics (Reed and Metcalf 1999:100-103). Two rock art sites with either Fremont or Anasazi iconography have been recorded along the extreme western edge of Garfield County (heed and Metcalf 1999:104). In the current project area, however, horticulture was limited and the hunting and gathering tradition most likely continued from the Archaic. The Aspen tradition is defined as the taxonomic equivalent to other Formative -era traditions, dating roughly from 400 BC to AD 1300 (Reed and Metcalf 1999:141): The Utes were the last hunter -gatherer group known to have inhabited the area, and the Protohistoric Period is marked by the incursion of EuroAmerican explorers into their territory. The Ute culture is best known from descriptions of the last 150 years when acquisition of horses, guns, and other exotic items from contact with EuroAmericans altered their original cultural patterns to a significant degree. Before extensive exposure to EuroAmerican culture, however, these people constructed wickiups for shelter, manufactured brown ware ceramics, and hunted with bows and arrows. Typically, arrow points are classified as Desert Side -notched and Cottonwood Triangular projectile points. Occasionally, Uncompahgre Brawn Ware ceramics are encountered. Buckles (1971) initially developed a taxonomic scheme for the Protohistoric era. The Escalante phase (A.D. 1500 to 1880) refers to components that are probably related to Ute 4 occupation of the area, while the Camel Back phase (AD. 1300 to 1500) may not be as attributable to the Ute culture. Over the last twenty years, several taxonomic schemes have been presented to address the expanding database of the Protohistoric period. Reed and Metcalf (1999:150) propose that the Protohistoric period be divided into the Antero and Canalla phases (Reed 1988). The Canalla phase begins at approximately A.D. 1100, when Uncompahgre Brown Ware appears in the region's archaeological record (Reed 1994), and terminates at A.D. 1650. Projectile points include the Desert Side -notched and Cottonwood Triangular types. Wickiups and similar brush structures were used for shelter, and people engaged in pedestrian hunting and gathering. Toward the end of the Canalla phase, limited quantities of European trade goods occasionally appear. The Antero phase, dating AD. 1650 to 1881, represents a shift to a fully equestrian lifestyle and is characterized by the addition of EuroAmerican trade goods into Ute material culture. Desert Side -notched and Cottonwood Triangular projectile points continue in use, but were probably increasingly replaced by metal projectile points and firearms. Uncompahgre Brown Ware was also made, and common EuroAmerican trade items include glass beads, metal cone tinklers, cartridges, tin cans, and bits. The Historic period in the region began with the first Euro -American explorers, who were members of the Dominguez-Escalante Expedition which passed through or near the project area in the late summer of 1776 (Burgess et al. 1980). Explorers were followed by trappers, government surveyors, miners, and ranchers. Fur trappers in search of beaver were some of the first EuroAniericans to enter west -central Colorado, and were actively exploiting the area from as early as 1810. Fort Uncompahgre, or Fort Roubidoux, was built in 1828 near the junction of the Gunnison and Uncompahgre Rivers to provide protection and trade for the trappers. The trappers were followed shortly by explorers, and in the early 1830s, the Old Spanish Trail was laid out for use by future travelers and settlers. The Northern Branch of the Old Spanish Trail followed the Gunnison River north to the Grand (Colorado) River, then west along the river into Utah (Mehls 1982:75). The Grand Junction area was first settled in the 1880s, and was aided by numerous water projects (Mehls 1982:134-135). Frit orchards and sugar beets were two of the many crops that comprised the backbone of the fanning economy in the Grand Valley, while cattle and sheep ranching rounded out the agricultural economy. The mining boom in the Rockies and farther west in Utah drove the expansion of the railways and fostered the development of agriculture, ranching and other local industry that began primarily to support the mining. The opening of vast portions of the west for settlement with the various homestead acts sealed the fate of the area.

The Grand Junction area was first settled in the 5 1880s, and was aided by numerous water projects (Mehls 1982:134435). Fruit orchards and sugar beets were two of the many crops that comprised the backbone of the farming economy in the Grand Valley, while cattle and sheep ranching rounded out the agricultural economy. Historic Period resources in the vicinity of the Class I area include isolated fords, trash dumps, homesteads, roads, and irrigation ditches. Previous Work The files of the Colorado Office of Archaeology and Historic Preservation (OAHP) COMPASS database and the files of the BLM-GJFO were consulted on March 11 and 16, 2009, respectively. The 1885 General Land Office plat was also examined at the BLM GJFO; no historic features were observed within the Class I study area. In the legal sections surrounding the project area there are no recorded cultural resources. Three projects have taken place in the legal sections surrounding the project area including: • Twenty-six Geotechnical Locations and Access Roads at SOHIO Pacific Oil Shale Property (1982, Gilbert Conunonwealth, BLM-GJFO CRIR 18824); • Occidental Oil and. Gas Pipeline (2004, Uncompahgre Archaeological Consultants, BLM-GJFO CRIR 14504-04); • Oxy Cascade Creek 797-06-22D Pipeline and Access Road (2007, Superior Consulting Archaeology, BLM GJFO CRUZ 16807-02). Results, Evaluation, and Conclusion Based on the results of previous inventories in the Class I area and on examination of the historic General Land Office plats, FAC recommends that the potential for prehistoric properties is moderate to low. However, historic linear features have been recorded. in the area just outside the scope identified for this Class L The features identified are related to Conn Creek road, other historic trails, or ditches developed during the settlement of the DeBeque area in the late 19th and early -to -mid 20th century. Many of the historic trails, road and ditches in the region have been impacted by continued use, maintenance and improvements made to facilitate their function and do not retain historic integrity. Any discovered segments of an original road grade, tri, or ditch should be considered for their possible historic integrity and significance, and should be preserved and protected.

Where available space allows, aboveground piping is installed out of the way of vehicular traffic. In cases where aboveground piping is situated in high traffic areas, bollards and/or warning signs will be installed. 17.0 impracticability [112.7(d)]: 112.7(d) If the containment and/or diversionary structures or equipment required by the rule to prevent a discharge can be implemented, they are referred to by the rule as practicable and are described in the Plan. If not practicable, the following provides a description of the impracticability. As discussed in Section 12.1, secondary containment around loading/unloading areas can create a potential explosion hazard by trapping flammable vapors near an engine (an ignition source) that often must remain running during the loading operations to power the transfer pump. Because the tank truck should not be parked or left standing near a building or in a depressed or enclosed area that will trap vapors or collect liquids which are ignitable, it is not practicable to have secondary containment for the loading/unloading areas.

All pipe supports are properly designed to minimize abrasion and corrosion and allow for expansion and contraction. 16.4 Aboveground Valve and Pipeline Examination 112.8(d) (4) (4) Regularly inspect all aboveground valves, piping, and appurtenances. During the inspection you must assess the general condition of items, such as flange joints, expansion joints, valve glands and bodies, catch pans, pipeline supports, locking of valves, and metal surfaces. You must also conduct integrity and leak testing of buried piping at the time of installation, modification, construction, relocation, or replacement. All aboveground valves and pipelines are scheduled for regular inspection to assess the general condition of items such as flange joints, expansion joints, valve glands and bodies, catch pans, pipeline supports, locking of valves, and metal surfaces. Integrity and leak testing of buried piping is also performed during installation, modification, construction, relocation, or replacement. OXY Cascade Creek Field SPCC Plan Page 20 KWh rivets, and bolts. You must promptly remove any accumulations of oil in diked areas. Any oil leaks identified through routine work activities or site inspections are promptly corrected by facility maintenance personnel. Minor spills due to Ieaks are cleaned up with absorbent material. A qualified spill contractor shall be used for Iarger spills and spills to navigable waters. 15.11 Appropriate Position of Mobile or Portable Oil Storage Tanks 112.8(c)(11) (11) Position or locate mobile or portable oil storage containers to prevent a discharge as described in Sec. 112.1(b). You must furnish a secondary means of containment, such as a dike or catchment basin, sufficient to contain the capacity of the largest single compartment or container with sufficient freeboard to contain precipitation. All mobile or portable oil storage tanks are placed in a means of secondary containment. Refer to the site specific forms in Attachment 1 for more information regarding the quantity, size, contents, location, and provided secondary containment for mobile or portable tanks. 16.0 Facility Transfer Operations [112.8(d)]: 16.1 Buried Piping Installation Protection and Examination 112.8(d)(1) Provide buried piping that is installed or replaced on or after August 16, 2002, with a protective wrapping and coating. You must also cathodically protect such hurled piping installations or otherwise satisfy the corrosion protection standards for piping in part 280 of this chapter or a State program approved under part 281 of this chapter. If a section of buried line is exposed for any reason, you must carefully inspect it for deterioration. If you find corrosion damage, you must undertake additional examination and corrective action as indicated by the magnitude of the damage. For information on specific well pad buried piping installation protection and examination refer to the site specific forms included in Attachment 1. The following are provided for the corrosion protection of flowlines: 1. Protective coatings 2. Cathodic protection (buried pipe) 3. Corrosion inhibitor is used to protect against internal corrosion when determined by testing or observation to be necessary. The following mechanical devices or controls are used for loss prevention or mitigation: 1. Check valves 2. High / Low pressure control OXY Cascade Creek Field SPCC PIan Page 19 hftWalsh heating coils that discharge into an open watercourse, or pass the steam return or exhaust lines through a settling tank, skimmer, or other separation or retention system. This section is not applicable as no internal hating coils are used. 15.8 Tank Installation Fail -Safe Engineered 112.8(c)(8) (8) Engineer or update each container installation in accordance with good engineering practice to avoid discharges. You must provide at least one of the following devices: (1) High liquid level alarms with an audible or visual signal at a constantly attended operation or surveillance station. In smaller facilities an audible air vent may suffice. (11) High liquid level pump cutoff devices set to stop flow at a predetermined container content level. (iii) Direct audible or code signal communication between the container gauger and the pumping station. (iv) A fast response system for determining the liquid level of each bulk storage container such as digital computers, telepulse, or direct vision gauges. If you use this alternative, a person must be present to monitor gauges and the overall filling of bulk storage containers. (v) You must regularly test liquid level sensing devices to ensure proper operation. The ASTs at the facility are constructed of welded steel in accordance with UL 2085, NFPA 20, and API standards, are grounded, and are compatible with the fuel products that they hold. High liquid level alarms are installed on several of the tanks at the facility. It is the intent of the owner to install high liquid level alarms on newly installed tanks. Not all tanks are equipped with high liquid level alarms; however, in all cases, qualified personnel are present during filling of bulk storage containers. Information regarding the presence of level alarm devices and the inspections and testing of these alarms is included on the monthly inspection forms included in Appendix B. 15.9 Observation of Disposal Facilities for Effluent Discharge 112.8(c)(9) Observe effluent treatment facilities frequently enough to detect possible system upsets that could cause a discharge to navigable waters. This section is not applicable, as no effluent treatment facilities are included in this Plan. 15.10 Visible Oil Leak Corrections from Tank Seams and Gaskets 112.8(c)(I0) Promptly correct visible discharges which result in a loss of oil from the container, including but not limited to seams, gaskets, piping, pumps, valves, OXY Cascade Creek Field SPCC Plan Page 18 15.4 Corrosion Protection of Buried Metallic. Storage Tanks 112.8(c)(4) Protect any completely buried metallic storage tank installed on or after January 10, 1974 from corrosion by. coatings or cathodic protection compatible with local soil conditions. You must regularly leak test such completely buried metallic storage tanks. This section is not applicable, as there are no buried metallic storage tanks on-site. 15.5 Corrosion Protection of Partially Buried Metallic Tanks 112.8(c)(5) Not use partially buried or bunkered metallic tanks for the storage of oil, unless you protect the buried section of the tank from corrosion. You must protect partially buried and bunkered tanks from corrosion by coatings or cathodic protection compatible with local soil conditions. There are several partially buried metallic tanks on-site. Information regarding the corrosion protection provided can be found on the individual site specific forms included in Attachment 1. 15.6 Aboveground Tank Periodic Integrity Testing 112.8(c)(6) (6) Test each aboveground container for integrity on a regular schedule, and whenever you make material repairs. The frequency of and type of testing must take into account container size and design (such as floating roof skid -mounted, elevated, or partially buried). You must combine visual inspection with another testing technique such as hydrostatic testing, radiographic testing, ultrasonic testing, acoustic emissions testing, or another system of non- destructive shell testing. You must keep comparison records and you must also inspect the container's supports and foundations. In addition, you must frequently inspect the outside of the container for signs of deterioration, discharges, or accumulation of oil inside diked areas. Records of inspections and tests kept under usual and customary business practices will suffice for purposes of this paragraph. Aboveground storage tanks, containment systems, and associated 'equipment are inspected on a monthly basis. During inspections, the above ground storage tanks, 'containment systems, surrounding surface areas, piping, valves, and all other applicable equipment are inspected for signs of deterioration and leaks. A formal visual external inspection will be performed every five years (API 653) or at the quarter corrosion -rate of the shell, whichever is less. Periodic internal inspections will be made in accordance with API 653 as well. Pressurized piping and leak detectors associated with the ASTs are tested annually in accordance with state regulations. 15.7 Corrosion Protection of Buried Metallic Storage Tanks 112 (7) Control of leakage through internal heating coils: 112.8(c)(7(7) Control leakage through defective internal heating coils by monitoring the steam return and exhaust lines for contamination from internal OXY Cascade Creek Field SPCC Plan Page 17 15.1 Tank Compatibility with its Contents 112.8(c) (1) Not use a container for the storage of oil unless its material and construction are compatible with the material stored and conditions of storage such as pressure and temperature. Information regarding tank compatibility with contents can be found in the site specific forms included as Attachment 1. In general, the material and construction of bulk storage containers are compatible with the material stored and conditions of storage such as pressure and temperature. 15.2 Secondary Containment 112.8(c)(2) Construct all bulk storage container installations so that you provide a secondary means of containment for the entire capacity of the largest single container and sufficient freeboard to contain precipitation. You must ensure that diked areas are sufficiently impervious to contain discharged oil. Dikes, containment curbs, and pits are commonly employed for this purpose. You may also use an alternative system consisting of a drainage trench enclosure that must be arranged so that any discharge will terminate and be safely confined in a facility catchment basin or holding pond. All bulk storage container installations are constructed so that a secondary means of containment is provided for the entire capacity of the largest single container and sufficient freeboard to contain precipitation. The secondary containment areas are sufficiently impervious to contain discharged oil. Specific information including the size and the configuration of the secondary containment structures at each well pad can be found in the site specific forms included in Attachment 1. Calculations conducted in order to determine whether the secondary containment structures were of sufficient size are included in Attachment 2 15.3 Diked Area Inspection and Drainage of Rainwater 112.8(c) (3) Not allow drainage of uncontaminated rainwater from the diked area into a storm drain or discharge of an effluent into an open watercourse, lake, or pond, bypassing the facility treatment system unless you: (1) Normally keep the bypass valve sealed closed. (ii) Inspect the retained rainwater to ensure that its presence will not cause a discharge as described in Sec. 112.1(h). (iii) Open the bypass valve and reseal it following drainage under responsible supervision; and (iv) Keep adequate records of such events, for example, any records required under permits issued in accordance with Secs. 122.416)(2) and I22.41(m) (3) of this chapter. Most stormwater which enters secondary containment areas that surround bulk storage containers is removed by natural infiltration and evaporation. Should drainage from dike/containment areas be necessary, it is performed using vacuum trucks. OXY Cascade Creek Field SPCC Plan Page 16 L= -Walsh 14.2 Valves used on Diked Area Storage 112.8(10(2) Use valves of manual, open -and -closed design, for the drainage of diked areas. You may not use flapper -type drain valves to drain diked areas. If your facility drainage drains directly into a watercourse and not into an on-site wastewater treatment plant, you must inspect and may drain uncontaminated retained stormwater, as provided in paragraphs (c)(3)(ii), (iii), and (iv) of this section. This section is not applicable, as no diked area drains or valves are used. 14.3 Plant Drainage Systems from Undiked Areas 112.8(b)(3) Design facility drainage systems from undiked areas with a potential for a discharge (such as where piping is located outside containment walls or where tank truck discharges may occur outside the loading area) to flow into ponds, lagoons, or catchment basins designed to retain oil or return it to the facility. You must not locate catchment basins in areas subject to periodic flooding. Facility drainage systems have been designed to handle stormwater events only. These drainage systems consist of ditches, culverts, and swales. 14.4 Final Discharge of Drainage 112.8(b)(4) If facility drainage is not engineered as in paragraph 0)(3) of this section, equip the final discharge of all ditches inside the facility with a diversion ,system that would, in the event of an uncontrolled discharge, retain oil in the facility. As discussed in the previous section, overall facility drainage is designed to handle only stormwater. All potential discharges will be contained by secondary containment structures designed with sufficient capacity to contain a discharge until clean up occurs. 14.5 Facility Drainage Systems and Equipment 112.7(e)(1) (5) Where drainage waters are treated in more than one treatment unit and such treatment is continuous, and pump transfer is needed, provide two `lift" pumps and permanently install at least one of the pumps. Whatever techniques you use, you must engineer facility drainage systems to prevent a discharge as described in Sec. 112.10) in case there is an equipment failure or human error at the facility. This section is not applicable, as no equipment is necessary in the facility drainage systems. 15.0 Bulk Storage Tanks/Secondary Containment [112.8(c)]: OXY Cascade Creek Field SPCC Plan Page 15 KWh It is the responsibility of each individual vehicle driver to closely inspect the vehicle drains and outlets for any discharges, loose caps, or necessary adjustments or replacements in order to prevent discharge while in transit. 13.0 Repair, Alteration, Reconstruction or Change in Service [112.7(1)]: 112.7(i) If a field -constructed aboveground container undergoes a repair, alteration, reconstruction, or a change in service that might affect the risk of a discharge or failure due to brittle fracture or other catastrophe, or has discharged oil or failed due to brittle fracture failure or other catastrophe, evaluate the container for risk of discharge or failure due to brittle fracture or other catastrophe, and as necessary, take appropriate action. As discussed previously in Section 9, per 112.6(c)(4), each aboveground container will be tested/inspected for integrity on a regular schedule and whenever material repairs are made. If the AST undergoes a repair, alteration, reconstruction, or change in service, it will be evaluated for the risk of discharge or failure due to brittle fracture or other catastrophe. Qualified contractors and personnel will perform all repair, alteration, and/or reconstruction activities according to accepted industry practices and regulations. 14.0 Facility Drainage [112.8(b)]: 14.1 Drainage Control 112.8(b)(1) Restrain drainage from diked storage areas by valves to prevent a discharge into the drainage ,system or facility effluent treatment system, except where facility systems are designed to control such discharge. You may empty diked areas by pumps or ejectors; however, you must manually activate these pumps or ejectors and must inspect the condition of the accumulation before starting, to ensure no oil will be discharged. Tank battery and separation and treating area dike/containment drains are not present at the sites. Should drainage from dike/containment areas be necessary, it is performed using vacuum trucks. If oil is detected in containment areas or in field drainage systems, the removal procedures and the requirements for disposition of the recovered product are included in Appendix C. Drainage from undiked areas is not confined in a catchment basin or holding pond. There are no bulk oil storage containers not within secondary containment present at the facility. OXY Cascade Creek Field SPCC Plan Page 14 AWalsh drainage system for tank car or tank truck loading and unloading areas. You must design any containment system to hold at least the maximum capacity of any single compartment of a tank car or tank truck loaded or unloaded at the facility. Condensate is unloaded from bulk storage tanks at each site using tank trucks. Secondary containment for tank trucks is not provided at the well pad sites based on several prohibitive and limiting site conditions. First, explosion hazards exist due to the potential for trapping flammable vapors near an engine (an ignition source). Therefore, a secondary containment or enclosed area is not practical. Second, very limited site sizes do not allow for the construction of additional containment specifically for the loading and unloading operations. Additionally, land uses require minimized surface impacts which preclude construction of major drainage systems at tank load out points. In order to maintain control of the loading and unloading operations, standard practices require that all tank truck loading is attended continuously by the track driver. In case of an incident, the truck driver can get to the controls to shut them off within 2 to 5 minutes. All loading and unloading trucks will be required to carry spill kits. 12.2 Warning or Barrier System for Vehicles 112.70)(2) Provide an interlocked warning light or physical barrier system, warning signs, wheel chocks, or vehicle break interlock system in loading/unloading areas to prevent vehicles from departing before complete disconnection offlexible or fixed oil transfer lines. The secondary containment structures (HESCO barrier or metal wall type) make up the barrier systems to prevent vehicle damage to the tanks at each pad. In cases where high traffic exists, metal or concrete bollards are installed. Refer to the field sketches contained in the site specific forms for detail on each well pad configuration (Attachment 1). Signs are posted as several of the individual well pads warning truck drivers to check all valves and connections to make sure they are securely tightened and closed before leaving the site. Example loading/unloading warning signs and procedures are included in Appendix F. 12.3 Vehicles Examined for Lowermost Drainage Outlets Before Leaving 112.70)(3) Prior to filling and departure of any tank car or tank truck, closely inspect for discharges the lowermost drain and all outlets of such vehicles, and if necessary, ensure that they are tightened, adjusted, or replaced to prevent liquid discharge while in transit. OXY Cascade Creek Field SPCC Pian Page 13 11.3 Starter Controls Locked 112.7(g)(3) Lock the starter control on each oil pump in the "off'position and locate it at a site accessible only to authorized personnel when the pump is in a non-operating or non -standby status. Information regarding the starter controls at each well pad can be found on the site specific forms included in Attachment 1. 11.4 Pipeline Loading/Unloading Connections Securely Capped 112.7(g)(4) Securely cap or blank flange the loading/unloading connections of oil pipelines or facility piping when not in service or when in standby service for an extended time. This security practice also applies to piping that is emptied of liquid content either by draining or by inert gas pressure. Information regarding the pipeline loading/unloading connections at each well pad can be found on the site specific forms included in Attachment 1. In addition, loading/unloading warning signs and procedures are included in Appendix F. 11.5 Lighting Adequate to Detect Spills 112.7(5) Provide facility lighting commensurate with the type and location of the facility that will assist in the: (i) Discovery of discharges occurring during hours of darkness, both by operating personnel, if present, and by non-operating personnel (the general public, local police, etc.); and (ii) Prevention of discharges occurring through acts of vandalism. No security lighting is in place, as it has been determined not necessary based on the overall security operations of the entire field. While no permanent site security lighting is used at the well pads, portable lighting is available for use during activities performed at night as well as for emergency operations. Additionally, permanent lighting is provided at the guard shacks as well as at the Gas Plant and Water Facilities.

API Tanks undergo: 1. Inspection by qualified inspection personnel when initiated by exception from Operational or Condition Examinations. 2. Periodic external andlor internal inspections by qualified inspection personnel are scheduled on the basis of corrosion rate and remaining life in accordance with industry standards. Brittle Fracture Consideration In the event that a field -constructed aboveground container undergoes a repair, alteration, reconstruction, or a change in service, the container is evaluated, in accordance with the relevant industry standard, for the risk of discharge or failure due to brittle fracture or other catastrophe. OXY Cascade Creek Field SPCC Plan. Page 9 KWh emergency response procedures for guidance on management and disposal of certain materials. 8.0 Containment and/or Diversionary Structures (112.7(c)]: 112.7(c) Provide appropriate containment and/or diversionary structures or equipment to prevent discharged oil from reaching a navigable water course. The entire containment system, including walls and floor, must be capable of containing oil and must be constructed so that any discharge from a primary containment system, such as a tank or pipe, will not escape the containment system before cleanup occurs. At a minimum, you must use one of the following prevention systems or its equivalent: (1) Onshore facilities: 8.1.1.1.1.1.1 Dikes, berms, or retaining walls sufficiently impervious to contain oil; 8.1.1.1.1.1.2 Curbing; 8,1.1.1.1.1.3 Culverting, gutters, or other drainage systems; 8.1.1.1.1.1.4 Weirs, booms, or other barriers; 8,1.1.1.1.1.5 Spill diversion ponds; 8.1.1.1.1.1.6 Retention ponds; 8.1.1.1.1.1.7 Sorbent materials. 8.1.1.1.2 (2) Offshore facilities: 8.1.1.1.3 (i) Curbing, drip pans; 8.1.1.1.4 (ii) Sumps and collection systems. Containment and diversionary structures are provided where appropriate. While the layout of each well pad varies, in general, secondary containment structures have been provided in order to prevent discharged oil from reaching navigable water course. The containment systems have been designed and constructed so that discharge from any of the primary containment systems (i.e. tanks) will not escape the containment system before cleanup occurs. In addition to secondary containment structures, in some cases diversionary structures such as ditches have been constructed in order to divert discharge away from water courses in the immediate vicinity of a potential spill source. The size and configuration of secondary containment structures at a particular well pad is based on the available space and the required containment of the tanks at that specific pad. Sketches and photographs of the secondary contahunent structures are included on the site specific forms contained in Attachment 1. 9.0 inspections, Tests and Records (112.7(e)]: 112.7(e)Conduct inspections and tests required by this part in accordance with written procedures that you or the certifiling engineer develop for the facility. You must keep these written procedures and a record of the inspections and tests, signed by the appropriate supervisor or inspector, with the SPCC Plan for a OXY Cascade Creek Field SPCC Plan Page 8 "Walsh The site specific forms for each of the well pads include summary tables which identify the quantities of each storage container (item 1) and the direction of flow (item 5). These forms can be found in Attachment 1. Discharge prevention measures, including procedures for routine handling of products (loading, unloading, facility transfers, etc.), are described in the loading/unloading procedures in Appendix F. Several scenarios have been evaluated to attempt to predict spill volumes and rates. In the first scenario a spill is predicted to occur from over filling of a tank due to the lack of a high level alarm. In this scenario, it is assumed that the loading truck would be pumping at approximately 20 gallons per minute. In a second scenario, a valve failure might result in a spill at a rate of 5 gallons per minute. The third scenario, involving a puncture or damage to the wall of a tank could potentially release at 250 gallons per minute. Again, each individual site will be addressed based on site specific conditions. While bulk storage containers at each of the well pads are handled individually, in general, bulk oil storage containers are placed inside of secondary containment. The capacity of secondary containment areas for bulk oil storage containers is sized to contain the capacity of the largest container plus allowance for precipitation freeboard. This method of establishing sufficient secondary containment capacity has been the industry standard and approved by EPA for years and is mentioned in the Preamble to the Final f' SPCC Rule (Federal Register Volume 67, Number 137). Piping or process equipment is either placed inside of secondary containment or operated in a manner to minimize the potential for leaks or spills. Drip pans are provided for equipment such as pumps, compressors, loading hoses, etc. that may have potential for drips and Ieaks . during operation. Equipment integrity assurance procedures and equipment inspections are key parts of these prevention efforts. The facility discharge discovery, response and cleanup capabilities are described in the discharge evaluation and event report and the emergency response procedures included in Appendices C and E, respectively. Housekeeping and early detection of leaks and spills are key parts of preventing oil from reaching waters of the U.S. Drainage ditches, process areas, and other areas where the potential of a spill entering a water source is most significant, are inspected on a regular basis. Prompt discovery, response and cleanup of oil will follow contingency plan procedures. The facility has established methods of disposal for recovered materials in accordance with applicable legal requirements in the emergency response procedures in Appendix E. In general, field personnel will coordinate the proper disposal of any waste materials as a result of a spill with the Operations Manager, with other assistance available as needed. Management and disposal of such materials will be conducted in accordance with applicable federal, state and local requirements. Personnel may also refer to the OXY Cascade Creek Field SPCC Plan Page 7 The Facilities Engineer will immediately report to the site and, if necessary, utilize equipment stored on-site to assist with cleanup operations. In addition, cleanup assistance can be obtained directly from Old West (contact information included in Appendix E). The Facilities Engineer will also contact theappropriate agencies and report the release. If there is a petroleum release or suspected release of harmful quantity to the navigable waters of the U.S., it will be reported to the following regulatory agencies immediately: 1) Colorado State Inspector of Oils Denver, CO 303-620-4029 2) National Response Center Washington, DC 800-424-8802 (24 hour phone) or US Environmental Protection Agency Region VIII Response Center One Denver Place - Suite 500 99918th Street Denver, Colorado 80202-2405 303-293-1788 (24 hour phone) When contacting these agencies, the following information must be provided: • responsible company/person, including exact address and telephone number; • name of person reporting the release; • date and time of release; • type of material discharged; • estimate of the quantity released; • waterway affected, including amount reaching water; • source of the discharge; • a description of all affected media; • cause of release; • damages or injuries caused by the discharge; • action taken to stop, remove, and mitigate the effects of the release; • whether an evacuation is needed; • names and/or organizations who have also been or will be contacted. 7.0 Potential Spill Predictions, Volumes, Rates, and Control [112.7(b)]: 112.7(b) Where experience indicates a reasonable potential for equipment failure (such as tank overflow, rupture, or leakage), the plan should include a prediction of the direction, rate of flow, and total quantity of oil which could be discharged from the facility as a result of each major type offailure. OXY Cascade Creek Field SPCC Pian Page 6 1WC� 4.3 Drainage Pathway and Distance to Navigable Waters This section should describe the facility's proximity to bays, rivers, streams (perennial or intermittent), creeks, ditches, flood control channels, storm drains, and other waterways. Hydrological systems should be diagramed or described. The well pads that make up the Cascade Creek Field are situated throughout a large area of varying terrain. Pads are located within one of three sub -fields: the Mesa, Logan Wash, and Valley fields. Each of these sub -fields has a separate drainage pattern based on the specific topography of each sub -field area. In some cases, pads are located within several feet of surface water bodies, and in other instances, flow distances exceed three quarters of a mile. Also, the flow paths range from flat terrain to extremely steep terrain. Flow patterns follow both natural and man-made drainage features. Each well pad is unique. Further detail regarding the drainage pathway and distance to navigable waters at each of the well pads included in this plan can be found in item 5 on the site specific forms. These forms are included in Attachment 1. 5.0 Physical Location and Diagram (112.7(a)(3)]: 112.7(a)(3) Describe in you Plan the physical layout of the facility and include a facility diagram, which must mark the location and contents of each container. The facility diagram must also include all transfer stations and connecting pipes. Figure 1 presents a Iayout of the sites within the Cascade Creek Field. The sites included in this plan are highlighted. The physical layout of each of the sites covered in this plan is included in Attachment 1. Also included in Attachment 1 is a site by site Iisting of containers, container contents, potential spill sources and an assessment of the existing secondary containment. 6.0 Reporting Information and Procedures (112.7(a)(4)]: 112.7(a)(4) Provide response information and procedures in your Plan to enable a person reporting a discharge to relate information on the exact address or location and phone number of the facility; the date and time of the discharge; the type of material discharged; estimates of the total quantity discharged; estimates of the quantity discharged as described in 112.10); the source of the discharge; a description of all affected media; the cause of the discharge; any damages or injuring caused by the discharge; actions being used to stop, remove, and mitigate the effects of the discharge; whether an evacuation may be needed; and the names of individuals and/or organizations who have also been contacted. Emergency personnel and equipment can be provided by the DeBeque Fire Authority (Call 911). If there is a petroleum release, the first responding employee that discovers the spill reports the spill to the Facilities Engineer or to the OXY Grand Junction office. Names and phone numbers for the individuals are located in Appendix A. OXY Cascade Creek Field SPCC Plan Page 5 �Wa1sh Numerous storage containers are used throughout the Field. The main purpose of these containers is the storage of produced materials, byproducts, water, treatment chemicals, and other liquids. There is a large amount of vehicle traffic to, from, and within the Field and a moderate amount of refueling of vehicles occurs on-site. Refueling and maintenance stations are treated in much the same manner as the other storage facilities on-site. Several minor treatment, preparation, and production processes take place at the Field. These processes take place in one of the following on-site facilities: gas plant, central water facility, evaporation ponds, production pits. Above ground piping and trucks are the primary modes transportation used for receiving and distributing products and raw materials at the Field. Pipes convey produced materials from the well pads to the gas plant. Trucks load and unload products and raw materials by hooking up to tank outlets and valves. 4.2 Facility Storage In this section describe all types of oil products storage at our facility including oil products stored in aboveground storage tanks (ASTs), underground storage tanks (USTs), oil filled electrical equipment (e.g., circuit breakers, transformers), spill tanks, oil/water separators, vapor recovery unit portable tanks, drum storage, and trucks which hold oil product and are parked on site. The Cascade Creek Field is made up of numerous natural gas well pads, each of which containing bulk storage containers used for the storage of products and materials key to the production and operation of the wells. Materials stored on-site consist of natural gas condensate, methanol, diesel, gasoline, bulk oil, used oil and other chemicals. Storage containers with the potential to spill at sites within the Field include aboveground storage tanks (ASTs), elevated tanks, and 55 -gallon drums. Each natural gas well pad is home to, among other various tanks, at least one natural gas condensate tank. In addition each pad may have containers containing methanol, corrosion inhibitors, water, diesel fuel, and other liquids key to the operation or maintenance of the wells. Further detail regarding the number, size, and contents of storage containers at each of the well pads included in this plan is included in the Bulk Storage Containers Tables (item 1) on the site specific forms. The identification and description of contents for each container listed in the tables is also noted on the site sketch diagrams included on the forms. These forms are included in Attachment 1.

This SWMP addresses construction activities associated with development of the natural gas resources for OXY USA WTP LP, in the Cascade Creek Common Plan of Development. A copy of this permit can be found in Appendix A. This field -wide SWMP was prepared to address storm water management practices at areas disturbed by construction and drilling activities associated with natural gas development within Cascade Creek (Permit No. COR -038414.) This SWMP is intended to be revised as necessary to address planned developments, new disturbances, and other changes needed to manage storm water and protect surface water quality. Storm Water Runoff Permitting Requirements The Federal Clean Water Act [Section 402(p)] requires that discharges of pollutants to waters of the U.S. from any point source be regulated by NPDES permits. In November 1990 the EPA published final regulations that established application requirements for storm water associated with construction activity for soil disturbances of 5 acres or more be regulated as an industrial activity and covered by an NPDES permit. In December 1999 the EPA published final Phase 11 NPDES regulations that established application requirements for storm water associated with construction activity for soil disturbances to be regulated as an industrial activity and covered by an NPDES permit. These regulations became effective July 1, 2002. On June 30, 2005, Colorado storm water regulations went into effect to require Colorado Discharge Permit System (CPDS) permits for storm water discharges from construction activities for (1 acre or greater) oil and gas activities. Federal permit coverage for these discharges was conditionally exempted from the Federal Clean Water Act by the 2005 Federal Energy Bill. On February 1, 2006, the CDPHE issued a letter clarifying that the CDPHE Water Quality Control Commission decided to maintain the existing requirements for storm water permitting for oil and gas construction sites greater then 1 acre. Project Description The Cascade Creek wells will be located within Sections 3, 4, 5, 6, 7, 8, 9, 10, 15, 16, 17, 18, 19, 20, 21, 26, 28, 29, 32, 33, and 34 of Township 6 South, Range 97 West; Sections 9, 10, 15, 16, 17, 18, 19, 20, 26, 35, and 36 of Township 7 South, Range 96 West; and Sections 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15, 16, 17, 18, 19, 20, 21, 22, 23, 24, 25, 27 and 28 of Township 7 South, Range 97 West, of Garfield County in Colorado. The town of Debeque, Colorado is the nearest population center. The Cascade Creek Common Plan of Development will be located approximately 13 miles north of DeBeque (Figurel). The current drilling and development plan includes pad construction, access road improvement/construction, pit construction, installation of associated facilities, well drilling, well completion, well testing and pipeline construction. The total area of site including the Page 1 Cascade Creek SWMP OXY USA natural gas well pads, the access roads and gathering system pipeline will be 25,000 acres. Total disturbed area is approximately 350 acres. Project Owner and Operator The property owner and operator is OXY USA WTP LP.

Contractor(s) will perform the actual construction and drilling, but all work will be supervised by OXY and all decisions will be made by OXY. This SWMP will be revised as necessary to address new disturbances, construction or operation. Depending on the type and location of new facilities there may be a need for inclusion of new and different BMPs. In general, new development should be planned with consideration for storm water quality (e.g. minimize disturbed area and maximize distance from surface water drainages, as practicable). Page 2 1 CONSTRUCTION SITE DESCRIPTION The following sections describe the site locations and provide a description of the construction areas( Runoff characteristics of these areas are also described. 1. a Nature of Construction Activity The Cascade Creek wells will be constructed using conventional cut and fill earthmoving techniques. Typically, the working pad surface will have dimension of approximately 200 feet by 400 feet. Specific pad dimensions vary depending on the planned drill rig, number of wells to be drilled from each pad, and local terrain conditions. The well pad will be graded to drain the pad surface to the reserve pit and to direct runoff from surrounding areas away from the well pad and reserve pit. Each pad may have a reserve pit that is approximately 60 feet by 250 feet. Reserve pits will be used during activities to contain drilling fluids and cuttings. The reserve pits will be designed, constructed, and reclaimed according to Colorado Oil and Gas Conservation Commission (COGCC) requirements. In areas that are disturbed by well construction, topsoil will be stripped and stockpiled near the site. Soil materials will be managed so that erosion and sediment transport are minimized. Nearby drainages will be protected by appropriate measures. If the well is not productive, it will be plugged according to COGCC rules and the pad area reclaimed to approximate pre -construction contours, Reclamation and final stabilization will be conducted as described in Sections 4 and 7. Cascade Creek Common Plan of Development well pads and facilities are surrounded by the following Colorado Land Cover Classification Systems: • Low Elevation Salt -Desert Scrub/Basin Big Sagebrush • Pinyon -Juniper Woodland, Mountain/Wyoming Big Sagebrush Shrubland • Mixed Mountain Shrubland including Oakbrush • Spruce -Fir, including Mountain Meadows A vegetation description for each Cascade Creek pad is provided in Tables 1 & 2. Vegetative cover surrounding Cascade Creek Common Plan of Development ranges from 30-85%. Regional precipitation amounts vary from 10.7 inches per year in Palisade, Colorado to 14.8 inches in Colbran, Colorado (Western Regional Climate Center). A Spill Prevention and Countermeasures Plan (SPCC) has been prepared for the Cascade Creek Common Plan of Development (Walsh, 2007). The SPCC plan will be updated as needed to incorporate new oil and gas facilities. 1. b Proposed Sequence for Major Activities Natural gas exploration, development and production activities are currently underway within the Cascade Creek Common Plan of Development. For new disturbances, Best Management Practices (BMPs) will be installed prior to, during, and immediately following construction as practicable with consideration given to safety, access, and ground conditions (e.g. frozen ground) at the time of construction. The development of natural gas wells is generally accomplished in three distinct work phases. The first, phase is the Development (Construction/Drilling/Completion/Initial Reclamation), the second phase is ti( Production (Operation/Maintenance), and the third phase is the Abandonment and Final Reclamation. Ef, work phase is briefly discussed below. Page 3 Development (Construction/Drilling/Conn letionllnitial Reclamation The Development phase includes the following activities; road and well pad construction, well drilling, well completion, gas line installation, and pad area reclamation. The well pad will be constructed and graded with a gentle slope to drain surface water to the reserve pit. Initial pad reclamation is accomplished by backfilling the reserve pit, contouring disturbed soils to conform with the surrounding terrain, replacing stockpiled topsoil, seeding of disturbed soil areas in order to reestablish a cover vegetation, and construction of erosion and sediment control structures. The completion of a well (gas production) generally triggers a one-year time period in which the reclamation phase of work should be completed. A listing of approved seed mixtures per vegetation land cover classification system identification is provided in Table 3. Production (Operation/Maintenance) The production phase includes the operation and maintenance activities during natural gas production. Gas pipelines are installed during this phase of work. Typical well pad equipment includes a wellhead, a separation unit and one to several 210-400-barrel capacity aboveground storage tanks (ASTs) containing condensate or produced water. Smaller sized ASTs may contain lube oil, methanol, and triethylene glycol. Reclamation activities during this phase include maintenance of revegetated areas and maintenance of the erosion and sediment control structures. Development of natural gas resources and associated construction activities will likely continue for the next 3 to 5 years. Natural gas wells in the Cascade Creek area are projected to produce for approximately 20 to 30 years. Abandonment and Final Reclamation When the natural gas production of a well is exhausted it will be abandoned. Upon well abandonment each borehole will be plugged, capped, and all surface equipment will be removed. Subsurface pipelines will be removed to specified locations and plugged. The pad area will be reclaimed by contouring disturbed soils to conform to the surrounding terrain, by replacing the stockpiled topsoil, by seeding of disturbed soil areas in order to reestablish cover vegetation, and by construction of erosion and sediment control structures as needed. Once stabilization is achieved, defined as uniform vegetative cover established with a density of at least 70 percent of pre-disturbance levels, a well pad may be removed from this SWMP for sediment controls. However, if petroleum hydrocarbons or other chemicals impact storm water as a result of industrial activities onsite, the well pad will maintain permit coverage and ensure SPCC plan BMPs are maintained. 1. c Estimates of Site Acreages The total permitted area of the Cascade Creek Common Plan of Development is approximately 25,000 acres. The total disturbed area is approximately 350 acres. 1. d Soil Data and Erosion Potential Runoff characteristics are based on site topography, soil type, and soil/vegetative cover. The soil types in this permitted area along with native vegetation land cover are described below in the Cascade Creek Soil Descriptions. The slopes range from 3% to steep rock outcroppings. Pre-disturbance ground cover varies from 30 to 85 percent. For specific pad percent ground cover information refer to Tables 1 & 2. Storm water runoff receiving waters include unnamed tributaries Conn Creek and Cascade Canyon. The ultimate receiving water is the Colorado River.

Vegetative cover surrounding Cascade Creek Common Plan of Development ranges from 30-85%. Regional precipitation amounts vary from 10.7 inches per year in Palisade, Colorado to 14.8 inches in Collbran, Colorado (Western Regional Climate Center). A Spill Prevention and Countermeasures Plan (SPCC) has been prepared for the Cascade Creek Common Plan of Development (Walsh, 2007). The SPCC plan will be updated as needed to incorporate new oil and gas facilities. 1. f Potential Pollution Sources Due to numerous sites within the Cascade Creek Common Plan of Development, a list of locations of potential pollution sources would be too expansive and not comprehensive. For an accurate location and listing of potential pollutants please refer to the site specific inspection forms. The following paragraphs list the possible pollutants. Potential pollution sources associated with construction sites and natural gas development include: • Sediment resulting from erosion of soil stockpiles and other areas cleared of vegetation; ▪ Sediment discharges from vehicle tracking; Page 6 • Leakage of fuels and lubricants from equipment and spills from fueling; • Trash and debris from clearing activities, construction materials, and workers and; • Leakage or spills from storage tanks and process equipment associated with the natural gas development activities. The most common source of pollution from pad and access road construction is sediment, which can be carried away from the work site with storm water runoff and impact the water quality of a receiving stream. Clearing, grading, and otherwise altering previously undisturbed land can increase the rate of soil erosion over pre -disturbance rates. Petroleum products can also be potential storm water pollutants. These products are. used in construction activities to power or lubricate equipment and include: fuel, gear oil, hydraulic oil, brake fluid, and grease. Debris from laydown areas, residue from equipment cleaning and maintenance, and solid waste generated from land clearing operations and human activity (trees, brush, paper, trash, etc.) present other potential pollution sources within the construction site. Additionally, one or more facilities may contain construction supplies such as various sized pipe, culverts, metal sheds, empty tanks, drums and vessels, fencing and stairs. Construction of new production facilities may require the use of concrete. Concrete wash out waters will be managed to prevent them from reaching waters of the state. Typically concrete wash out waters will be diverted to the well pad flare pit or other type of earthen impoundment to capture and evaporate wash out water. Loading and unloading of condensate and produced water from above ground storage tanks are common and regular activities within the Cascade Creek. Spills and or tank over flows can contaminate storm water runo Magnesium chloride solution or other chemical dust suppressants may be applied during the summer to unpaved roads to order to reduce fugitive dust generation. Magnesium chloride solution is used in the winter for roadway deicing and in the summer for dust suppression by county and state government entities. The solution is typically delivered to the site by contractors in Department of Transportation (DOT) approved tanker trailers and generally is quickly applied to the road surface. Occasionally, depending on work site conditions, the tanker trailers may be staged along the road until ready for application (typically no longer than overnight). Spills or leaks from potential sources are described in the SPCC plan; the SPCC plan can be located at the Conn Creek Facility. Response to certain events may require specialized training due to health and safety concerns. For a list of down -hole chemicals/MSDS inventory used during development activities please refer to Appendix B. 1. g Anticipated allowable non-stormwater discharges Non-stormwater discharges are not expected from the construction projects. Possible exceptions include fire prevention/suppression or dust control activities. If there are any uncontaminated springs located within the construction sites, they will be listed on the site specific maps. Landscape irrigation return flow, construction dewatering, and concrete washouts are slated to be a part of this operation. If these are encountered, they will be noted in the SWMP and an the site specific maps. Construction dewatering will also be covered under the appropriate permitting if found. 1. h Receiving waters f For a list of the receiving waters for the Cascade Creek Common Plan of Development, please refer to Tawe 4 -OXY Drainages spreadsheet.

BMPs will be chosen according to the potentials on a case by case basis. 3) management of contaminated soils will be done by containment immediately and disposing of them at an appropriate disposal facility. 4) loading and unloading operations will be evaluated and identified for potential for pollution. The following is the procedure fordealing with liquid loading and unloading procedures; Oxy/Cascade Creek Water Handling Procedure: * Authorization for Cascade Creek on -lease water movement shall be approved by OXY Plant Operator, Production Technician or Production Coordinator * Point of origin and discharge shall be identified prior to the movement of any water (produced, flowback or fresh). * Discharge valve at point of discharge shall be verified in open position and secured in open position. * Operator shall drive distribution system route verifying all risers are blind flanged (tapped w/needle valve) and valves are properly secured open. * Operator shall be present at discharge point before transfer pumps are started and engaged. * Operator shall inspect transfer pump according to check -list to identify and correct any operational issues. * Point of origin operator shall notify point of discharge operator of intent to engage and pump water. * Point of origin operator shall monitor rate and pressure maintaining acceptable limits within the design capabilities of distribution system. * Point of discharge operator shall monitor discharge into permitted water storage pond. * Point of discharge operator shall then drive distribution route and inspect for leaks or spills. * Upon completion of water movement, lines shall be purged of all liquids to prevent freezing, pumps shall be drained and properly secured, and all valves shall be secured properly. Spills will be handled according to the SPCC guidelines. 5) outdoor storage activities will be evaluated for potential to pollute StormWater runoff. Appropriate BMPs will be implemented on a case by case basis. Containment and prevention of contact with stormwater will be achieved by keeping materials with potentia! for pollution covered or enclosed in containers or packaging. 6) vehicle and equipment maintenance and fueling procedures require the operators to ensure that no fluids or materials are spilled. If they are spilled, they will be immediately contained and disposed of at an appropriate disposal facility. 7) significant dust or particulate generating processes will be evaluated and regulated by the application of water to eliminate possible wind erosion or transport. 8) routine maintenance activities involving fertilizers, pesticides, detergents, fuels, solvents, & oils will be very infrequent. When applying pesticides or herbicides, wind and moisture conditions will be evaluated and if either are found to be present and could possibly lead to contamination, such procedures will be delayed and attempted again when conditions are conducive to application without elevated pollution possibilities. Page 9 9) on-site waste management practices (waste piles, liquid wastes, dumpsters, etc.) will be enacted on all sites. Trash receptacles will be located on all active sites. Good housekeeping principles will be enacted throughout the entire permitted area. Disposal will be by contractors with appropriate handling equipment. 10) concrete truck/equipment washing, including the.concrete truck chute and associated fixtures and equipment will be infrequent within the permitted area. These procedures are covered under the permit. If washing of concrete trucks and equipment takes place, the water will be contained in an earthen basin. The location will be noted on site specific maps. 11) dedicated asphalt and concrete batch plants will not be present within the permitted area. 12) non -industrial waste sources such as worker trash and portable toilets will be contained in receptacles designed for the specific purpose. These will be disposed of by contractors with specially designed equipment and dispose ofaccording to local requirements at appropriate facilities. 13) other areas or procedures where potential spills can occur will be evaluated on a case by case basis and BMP's will be implemented according to the specific potential for pollution. 3.c BMPs for StormWater Pollution Prevention 3.c.1 Structural Practices The description and application practices of structural practices available and/or implemented can be found in the BMP manual. The location of structural BMPs will be found in the site specific maps. 3.c.2 Non -Structural Practices The description and application practices of non-structural BMPs available and/or implemented will be found in the BMP manual. The location of non-structural practices will be found in the site specific maps. 3.c.3 Phased BMP installation For a list of phased BMP installations, please refer to Table 2. 3.c.4 Materials Handling and Spill Prevention Fuels and Materials Management Petroleum products which may be present at the construction site include: gasoline, diesel fuel, lubricant oils, hydraulic oils, used oils, and solvents. Gasoline and diesel fuel will be stored in portable storage tanks with secondary containment. Lubricant, hydraulic, and miscellaneous oils and solvents will be stored in 55 -gallon or smaller containers. Pollutants from petroleum products used during construction activities adhere easily to soil particles and other surfaces. In case of a spill or leak, soils contaminated with petroleum products will be contained and removed to a proper disposal site. Proposed soil erosion and sediment control practices will aid in retention of spills or leaks. Use of secondary containment and drip pans will reduce the likelihood of spills or leaks contacting the ground. Proposed maintenance and safe storage practices will reduce the chance of petroleum products contaminating the road site. Oily wastes such as crankcase oil, cans, rags, and paper containing oils will be placed in proper receptacles and disposed of or recycled. An additional source of petroleum contamination is leaks from equipment and vehicles. Routine daily inspections will be conducted to identify leaks and initiate corrective actions, if needed. The following guidelines for storing and managing petroleum products will be used: • All product containers will be clearly labeled. • Drums will be kept off the ground within secondary containment and stored under cover if needed. • Fuel tanks will be stored within secondary containment. • Lids of drummed materials will be securely fastened. • Emergency spill response procedures will be available on-site. Persons trained in handling spills will be on call at all times. Page 10 • Spill clean up and containment materials (absorbent, shovels, etc.) will be easily accessible. Spills will be immediately cleaned up and contaminated materials will be properly stored on site until they can b disposed of in accordance with applicable regulations. • Storage areas and containers will be regularly monitored for leaks and repaired or replaced necessary. Contractors and subcontractors should be reminded about proper storage, handling and transferring of petroleum products or other hazardous materials during safety meetings. Oxy's Health and Environmental Regulatory Advisor (HES) will coordinate agencies reporting and statements. AU spills and releases of exploration and production waste or produced fluid exceeding 5 barrels (210 gallons) including those contained within unlined berms, shall be reported in writing on the COGCC Spill/Release Report Form 19 within 10 days of discovery of the spill. All spills/releases that exceed 20 barrels (840 gallons) of exploration and production liquids/waste shall be verbally reported to the COGCC at (303) 894-2100 within 24 hours of discovery. Spills or releases of any size that impact or threaten to impact any waters of the state, residence or occupied structure, livestock or public byway, shall be verbally reported to the COGCC as soon as practical after discovery (COGCC Rule 906). If the spill may reach waters of the state (which includes surface water, ground water and dry gullies or storm sewers leading to surface water), it must also be reported immediately to the Colorado Department of Public Health and Environment (CDPHE) at 1-877-518-5608. Spills or releases of more than 25 gallons of refined petroleum crude oil products such as gasoline, diesel fuel, oil, or derivatives of mineral, animal or vegetable oil shall be reported to the state of Colorado Division of Oil and Public Safety at (303) 318-8547 within 24 hours. A hazardous substance release in any amount which enters or threatens to enter waters of the state shall be reported to Colorado Department of Public Health & Environment (CDPHE). •( All spills, leaks, or overflows that result in the discharge of pollutants will be documented. Other Chemicals Products Management Additional materials will be used and stored on site for use in construction. These materials will be stored appropriately and managed to minimize spills and leaks. Storage areas will be regularly inspected and any minor spills or leaks will be cleaned up immediately. Materials Management The construction contractor will maintain a laydown or staging area for equipment and materials storage on site. These areas will be maintained with good housekeeping and will be inspected on a regular basis for spills, leaks, and potential of materials commingling with storm water runoff. 3.c.5 Dedicated Concrete or Asphalt Batch Plants There will be no dedicated Concrete or Asphalt batch plants within the permitted area. This SWMP will be amended if this changes in the future. 3.c.6 Vehicle Tracking Control Vehicle tracking control will be minimized by the construction of roads and travel areas by good engineering principles. Roads will be properly graded to control runoff and erosion. Road surfaces will be upgraded by the addition of gravel or roadbase being placed on the roadway surface. BMPs will be installed along roadways to control runoff and sediment. 3.c,7 Waste Management and Disposal including Concrete Washout Waste Management and Disposal Page 11 Weil pad construction and drilling will generate various other wastes during the course of construction (please refer to the SPCC plan & the Waste Management Plan (WMP). Other wastes may include the following: Sagebrush, shrubs and trees from clearing operations; Trash and debris from construction materials and workers; Drill cuttings, drilling fluids; and Sanitary sewage. Each of these wastes will be managed so as to not contribute to storm water pollution. Construction trash and debris will be collected in containers and hauled off-site for disposal in suitable landfills. Sanitary waste will be containerized in portable toilets or other 'storage tanks with waste materials regularly pumped and transported off-site for disposal at approved facilities. 3.0.8 Groundwater and Stormwater Dewatering Stormwater runoff will be separated from contamination and dewatering by diversion and grading. The two will not be allowed to come in contact with each other. This is not anticipated at this time. if in the future dewatering of any kind takes place, the SWMP will be amended to reflect the changes. For the installation and implementation details and specifications associated withal BMPs, please refer to the BMP manual. 4 FINAL STABILIZATION AND LONG TERM STORMWATER MANAGEMENT Areas which have been disturbed are considered to be stabilized when a uniform vegetative cover with a density of 70 percent of the pre-disturbance levels has been established or when an equivalent permanent, physical erosion reduction method is in-place. The disturbed areas will be seeded and mulched for final stabilization. Table 3 contains state approved seed mixtures and distribution rates for the Cascade Creek area. Typical Pure Live Seed (PLS) application rates are recommended to be doubled if seeding is performed by hydroseed or broadcasting. Seed mixtures and application rates are also specified in Application to Drill documents and are based upon several factors including facility and well pad surrounding vegetation, soil types, elevation and surface relief. Areas not used for facilities, access roads, materials storage yards, or other work areas will be stabilized with vegetation. Areas that are.stabilized with vegetation will be considered to have achieved final stabilization when a uniform stand of vegetation with a density of at least 70 percent of the pre-disturbance has been established. Sprayed on mulches and other slope stabilization materials may be used in combination with seeding techniques in select areas to promote and establish surface vegetation cover. Other areas which may include facilities, access roads, materials storage yards, and other work areas will be stabilized with the use of permanent, physical erosion reduction methods which include, but are not limited to: • Surface hardening — covering of the soil surface with hardened products such as concrete or asphalt pavement. • Surface covering — covering of the surface soil with structure that inhibits contact of precipitation with the soil surface which is generally considered to be placement of a structure (building or tank) over the soil surface. • Gravel surfacing — gravel surfacing will be applied in areas such as access roads, materials storage yards, and other work surfaces. Some gravel may be lost due to erosion from intense precipitation events or due to vehicle traffic. Gravel surfaces will be periodically inspected to determine the need for gravel replacement. Gravel surfaces will be replaced or repaired (through grading) when inspection reveals that the gravel surface is no longer effectively covering the soil surface. Page 12 5 INSPECTION AND MAINTENANCE To meet requirements of Storni Water General Permit No. COR -038414, inspection and maintenance erosion and sediment controls must occur during the construction project. Continued inspection a�-\ maintenance is required for specific structures after construction is completed. A complete list of active inspection locations, site diagrams and site specific storm water BMPs are provided in the inspection report book kept with the SWMP. Inspections will occur at least once every 14 calendar days and after a precipitation event or snowmelt events that cause surface erosion. The inspection of stormwater BMPs serves as a preventative maintenance plan for the control devices and practices designed to prevent and minimize the pollution of state waters. The inspections procedures will document the following items; 1) The inspection date; 2) Name(s) and title(s) of personnel making the inspection; 3) Location(s) of discharges of sediment or other pollutants from the site; 4) Location(s) of BMPs that need to be maintained; 5) Location(s) of BMPs that failed to operate as designed or proved inadequate for a particular location; 6) Location(s) where additional BMPs are needed that were not in place at the time of inspection; 7) Deviations from the minimum inspection schedule as provided in Section C.6.a above; 8) Description of corrective action for items 3, 4, 5, and 6, above, dates corrective action(s) taken, and measures taken to prevent future violations, including requisite changes to the SWMP, as necessary; and 9) After adequate corrective action(s) has been taken, or where a report does not identify any incidents requiring corrective action, the report shall contain a signed statement indicating the site is in compliance with the permit to the best of the signer's knowledge and belief. Permanently stabilized areas will be inspected at least once per month. A log of inspections will be completed and maintained at the Conn Creek Facility, and the Colorado office for a minimum of three years. Inspections are not required for disturbed areas when snow cover exists over the entire site for an extended period as long as melting conditions do not exist. Part I.D.6(a)(3) • Snow cover conditions where there is no risk of surface erosion can exist at high elevations within the Colorado mountains during some periods of the year. It is not necessary for inspections to be conducted during these periods. (taken from Public response 5/31/07) Water quality will be visually assessed for all receiving streams and discharge areas during each inspection if present. Disturbed areas and material storage areas that are exposed to precipitation will be inspected for evidence of pollutants entering nearby drainages. Check dams, wattles, and other BMPs will be inspected for evidence of deterioration, under -cutting, and build up of sediment. Sediment will be removed when it has built up one-third to one-half the height of the hay bales or wattles. Roads used for vehicle access will be inspected for evidence of off-site sediment transport. For maintenance procedures of BMPs, please refer to the BMP manual. This will also show criteria for maintenance. ( ; The SWMP will be modified as necessary whenever there is a change in design, construction or operation that changes the potential for pollutant discharge to waters of the state. Page 13 An inspection report summarizing the scope of the inspection, the name of the person conducting the inspection, date of inspection, and observations relating to the implementation will be. prepared. An inspection report is provided in Appendix D. Actions taken to modify storm water control measures will be recorded and maintained with the SWMP. If no deficiencies are found during the inspection, the report contains a certification statement that the site is in compliance with the SWMP and the General Permit. Personnel performing facility inspections such as access roads, well pads or other operational facilities will record site conditions on the Storm Water Field Inspection Report form in Appendix D. When deficiencies are discovered, the OXY Storm Water Administrator will be contacted and will direct designated subcontractors to perform BMP maintenance or replacement.

This operation includes drilling, producing wells with associated production equipment and structures, several miles of natural gas and water gathering lines, a compressor(� station and . a natural gas processing plant. The district office for Rockies is located in Grand Junction, Mesa County, Colorado. The corporate headquarters and support office for OXY -Rockies operations is in Houston, Texas. Most of the OXY -Rockies operations in Garfield 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 - Rockies compressor and pipeline systems fully complywith 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 triethylene glycol dehydration units are located at well locations and at the Conn Creek Treating Facility. The OXY -Rockies Conn Creek Treating Facility treats incoming natural gas for reduction of carbon dioxide through the use of Diethanolamine (DEA), as required prior to acceptance into the distribution pipelines. The gas processing facility is not staffed 24 hours per day; however, emergency contacts are posted at the entry to the facility or with the 24 hour security guard force at the property entrance. 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. Revised : 06/25/2008 OXY -Rockies ERP Page 4 Public Safety OXY-Rockies has operating procedures in place that are intended to protect the public and employees from undue harm. In addition, the Company follows strict codes of compliance for the )rotection of public and Company property and the natural environment, When a concern for public safety is encountered within the OXY-Rockies area of operations, OXY-Rockies should be notified immediately!!/ OXY-Rockies 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. 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 operations. The degree to which this emergency response plan will be activated will depend entirely on the nature of the occurrence. The Rockies Employee Emergency Response (ERP) Manual will be reviewed and updated annually to reflect current activity and to increase effectiveness of the plan through discussions among all people involved. This ERP has been shared with Garfield County officials including the Local Emergency Response Commission (LEPC). The plan has also been distributed to the Mesa County Fire and Emergency Services' Department in DeBeque, Colorado. OXY-Rockies coordinates routine visits to the OXY project area with the local responding units to better familiarize the responders and the OXY-Rockies employees with changes to current facilities, locations and hazardous substances which may be encountered during an actual emergency. These visits may include providing emergency services with access points, safe approach procedures and chemicals 'sed and/or stored on OXY property. The routine site visits also include training for OXY mployees and contractors on project layout, established muster locations and fire protection equipment. Many times, this information can mean ready control of a fire or other emergency instead of a disaster. Revised : 06/25/2008 OXY-Rockies'ERP Page 5 Emergency Response Plan (ERP) Outline I. Emergency Recognition and Prevention In the event of an emergency resulting from industrial accident, forces of nature, or enemy action,( there are certain problems that can be anticipated. 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 and property. For the purpose of this pian, 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. IL Emergency Alerting and Response Procedure Once an employee recognizes the occurrence of an emergency, he/she will notify their immediate supervisor who will determine if the emergency is of such a magnitude that outside help will be needed. This judgment may be influenced by the nature of the emergency and the presence of hydrocarbon vapors. If help is needed, the immediate supervisor will take the following steps: ( Notify the appropriate lines of authority and emergency response agencies as follows: A. Notify DeBeque Fire Protection District. B. Call law enforcement officers to help control traffic and the public. 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. At the current time there are no residents within the project area. There are however ranching interests in the area 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 -Rockies and all potentially affected personnel. t� Revised : 06/25/2008 OXY -Rockies ERP Page 6 111. Personnel Roles and Lines of Authority In the event of an emergency involving injury to OXY employees and/or contract personnel, Imediate care shall be provided to the injured to abate any life-threatening injuries (e.g.; cardiac arrest, breathing stopped, and profuse bleeding). i - Notification to OXY -Rockies 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 the cover page of this plan shall be notified as needed. In the case of a serious emergency, the supervisor, or the designee shall notify the OXY -Rockies Operations Manager and HES Personnel. Notification shall then be made to the General Manager and the Occidental Oil and Gas Corp. (OOGC) HES Department, as soon as possible, in accordance with 000C Procedure 60.400.110 "Incident Reporting and Investigation". It is essential that all personnel are familiar with the location, operation and properly trained on fire extinguishers. Personnel 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. Site Security and Control The supervisor or designee shall be responsible for assigning company employees or contracted scurity forces to provide traffic control and establish a secure perimeter prior to being relieved by C Qcal emergency response personnel. V. Evacuation Routes and Procedures Depending on the emergency, personnel shall evacuate to a location upwind, 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. Evacuation routes, procedures and pre -selected muster points should be identified and confirmed at each pre -job and regularly scheduled safety meeting. VI. Media Guide All inquiries/requests for information from the media and the public should be referred to the OXY - Rockies Operations Manager or Asset Manager.

You will not reach a local dispatcher. It is critical that the following information is provided when emergency services are needed in the OXY field: • Name and Phone Number of Caller. • Exact Location of Emergency- Provide Lat/Long and Elevation, at a minimum. This can be found in all Drill Plan Books located at Company Man and Tool Pusher Trailers. It is also located on new location signs. • If Lat/Long is not known, provide driving directions and plan to meet responding agencies at a suitable rendezvous point and inform personnel where that will be and that someone will be at the appointed place to meet them. Give landmarks, mileage and any other information to help responders find your location. Revised : 06/25/2008 OXY -Rockies ERP Page 10 Be aware that it may require more than one person to guide emergency personnel. (ambulance and fire may show up at different times) • Determine any hazardous substances located in or near the incident location • Provide number of victims. • Provide Mechanism of Injury (i.e. motor vehicle rollover, slip/trip/fall from elevated level, struck by heavy object, head-on collision, etc.) • Describe, to the best of your ability, the Type of Injury(ies) (i.e. Amputation, burn, sprain/strain/fracture, crushing, poisoning, loss of consciousness, etc.) • STAY ON LINE WITH THE DISPATCHER UNTIL TOLD TO HANG UP. DO NOT GET AGGRAVATED WITH THE TIME TAKEN TO GATHER INFORMATION. THE DISPATCHER WILL SEND ASSISTANCE WHEN THEY HAVE ALL PERTINENT INFORMATION GATHERED. THEY WILL NOT SEND RESPONDERS INTO A HAZARDOUS ENVIRONMENT. DISPATCHERS ARE TRAINED TO GATHER INFORMATION FOR THE RESPONDERS AND THEY ARE YOUR LINK TO GETTING HELP AS SOON AS PRACTICAL. 6. If the accident is severe enough, then it is feasible to call in flight support from St. Mary's CareFlight Helicopter. Refer to the attached brochure on "How To Prepare A Landing Zone" and to area maps with designated helipad locations. 7. Notify Supervisor or their designee Supervisor or their designee should: • Make sure EMS has been activated (See Item 5) • Notify other company personnel to perform previously discussed & planned rotes to secureg,., the area, assist in first aid, assist in evacuation, guide EMS etc. 8. Report any incident to the OXY -Rockies Management Team IMMEDIATELY. ** In some instances it may be more practical and efficient to notify the supervisor first and have them call EMS. See attached Emergency Contact List and the OXY -Rockies Contact List. Key Tips On How To Recognize Injury(ies) and Provide Initial Care: • Activate Emergency Medical Services' Assistance BEFORE it is too late - Call for help early. If it looks bad, feels bad, smells bad; it is probably bad. • ALWAYS activate the local (DeBeque) ground emergency service, even if you have notified CareFlight. Many times, the helicopter cannot reach an area because of bad weather conditions or a higher priority call out. Ground ambulance will verify landing zones and can provide guidance into an area for the helicopter. • DO NOT CAUSE MORE HARM AND DO NOT BECOME ANOTHER VICTIM BY RUSHING INTO A HAZARDOUS ENVIRONMENT. • Only provide care to the level of your training. • DO NOT move a victim unless there is imminent danger that could cause more harm. If available, communicate with CareFlight through the Emergency Services' radio channel for all landings The frequency is on all OXY -ROCKIES radios.

Evacuation drills/Training Flowchart 4 Fire prevention checklist Revised : 06/25/2008 OXY -Rockies ERP Page 26 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. According to the Colorado Department of(( Local Affairs, "The state saw the worst wildfire season in its history in 2002 with 3,072 wildfires burning over 600,000 acres - the most acreage in the nation following Alaska and Oregon. Three hundred -eighty houses and 624 outbuildings were lost. Insurance claims reached $79,3 million and firefighting and emergency rehabilitation efforts exceeded $200 million." 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 gerieral public and to OXY should unexpected conditions arise which create a concern for public safety. Ali OXY employees, contractors, sub -contractors, or anyone on. OXY -owned property should have the Emergency Response Plan (ERP) Manual available on hand 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. EMERGENC 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 wildland 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 Revised : 06/25/2008 OXY -Rockies ERP Page 27 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. 'n 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 from lit cigarettes. Cigarette fires cause an estimated $100,000 in the U.S. per year. 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 rear flammable liquids or gases. iFz k Flaring Another potential fire hazard is flaring on the drilling locations. 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 safely dispose of gases that occur in the production and processing of natural gas. The flare is always extended over the pit at a location, greatly reducing the chance for sparks to ignite a fire. In emergency situations, flaring provides a safe way to stabilize equipment. Flaring is always performed at well -site locations where there is no vegetation growth, decreasing the fire danger even more. 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 wildland fire. Every contractor who intends Revised : 06/25/2008 OXY -Rockies ERP Page 28 to perform one of these operations for OXY must have a Hot Work Permit 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. That is one of the main reasons why OXY contracts the security guards. They have a daily log of every individual that accesses OXY property. First of all notify someone of the fire, whether it be your supervisor, coworker, etc. Second, call the DeBeque Fire Department immediately at (970) 242- 1234; the sooner the fire department is dispatched, the quicker the response time will be. 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 - Pullthe 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 : 06/25/2008 OXY -Rockies ERP Page 29 hose andl or nozzle 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. You should become familiar with the alternative evacuation routes on the mesa/valley. There are (4) alternative routes of escape from OXY 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. Where To Go Once you have evacuated the area, the primary muster point for each individual would be the DeBeque baseball field, which is north of DeBeque on the west side of County Road 45. 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 Blanca 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. 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. Revised : 06/25/2008 OXY -Rockies ERP Page 30 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 wildland 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. To ensure the safety and health of occupants in the temporary housing units, inspections will have to be conducted on a monthly basis. The temporary housing units are being assessed per NFPA Life Safety Code, OSHA regulations, and 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. "No Smoking" signs shall be posted at fire hazard areas. Matches and all smoking equipment may not be carried into "No Smoking" areas. Butt disposal containers must 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 and shall be monitored for trash and debris on a daily basis. Revised : 06/25/2008 OXY -Rockies ERP Page 31 • 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 written OXY approval, but must be 50 feet away from the well -head. • Vegetation must be cleared within a 10 foot distance around the facility. • 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. • All small gas/diesel containers must be stored at least 50 feet away from the temporary facility, placed within secondary containment, 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 and leak detectors 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. • All temporary housing units located on OXY property will be monthly inspected and/or searched. 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. Fire drills need to be conducted to each hitch on a monthly basis. Employees need to know the Fire Prevention Plan, so when the unexpected does happen, they will be ready. Revised : 06/25/2008 OXY -Rockies ERP Page 32 The OXY Management Team will distribute an Emergency Response Plan (ERP) Manual containing the Fire Prevention Plan 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 resource 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.?

ECOLOGICAL INFORMATION Ecotoxlcity Data: Fate and Transport: Biodegradation: Bioconcentration: Aquatic Toxicity: Additional Ecological Information: Gas -phase methane will be very slowly degraded in the atmosphere by reaction with photochemically-produced hydroxyl radicals; the half-life for this reaction In air is estimated to be about 6 years.The biodegradation half life of methane was estimated to range from 70 days to infinity based on gas exchange biodegradation experiments conducted in model estuarine ecosystems. An estimated BCF of 1 suggests the potential for bioconcentration in aquatic organisms is low. Hydrolysis is not expected to be an important environmental fate process since methane lacks functional groups that hydrolyze under environmental conditions. If released to soil, methane is expected to volatilize from soil (both moist and dry) based upon its vapor pressure and an estimated Henry's Law constant of 0.66 atm - cu m/mole. 13.

HANDLING AND STORAGE General:- Electrical installations and equipment in hazardous locations should be installed according to the National Electric Code (U.S.A.). Empty containers retain residue and may be hazardous. Do not pressurize, cut, heat, weld or expose such containers to sources of ignition. . Handling Procedures: Avoid contact with skin and eyes. Remove and wash contaminated clothing before re- use. Keep contaminated clothing away from sources of ignition. Bond and ground all equipment when transferring from one vessel to another. Can accumulate static charge by flow or agitation. The use of explosion -proof equipment may be required by local fire codes, Storage Conditions: Keep containers tightly closed in a cool, well -ventilated place. Keep away from heat and sources of ignition. May be subject to storage regulations: U.S. OSHA 29 CFR 1910.106. Store only in approved containers. Keep away from incompatible materials. Incompatible Substances: Oxidizing materials. Additional information: Although Radon -222 levels which may be in the product represented by this MSDS do not present any direct Radon exposure hazard, customert should be aware of the potential for Radon daughter buildup within their processing systems. Radon -222 is a naturally occurring radioactive gas which can be a contaminant in natural gas. During processing, Radon tends to concentrate in liquefied petroleum gas streams and in product streams having a similar boiling point range. industry experience has shown that this product may contain small amounts of Radon -222 and its radioactive "daughters." The actual concentration of Radon -222 and radioactive daughters in the delivered product is dependent on the geographical souce of the natural gas and storage time prior to delivery. Process equipment, such as lines, filters, pumps and reaction units, may accumulate radioactive daughters and emit gamma radiation during operation. A potential external radiation hazard exists at or near any pipe, valve, or vessel containing a Radon -enriched stream, or containing internal deposits of radioactive material due to the transmission of gamma radiation through its wall. Field studies reported in the literature and conducted by company personnel at selected sites have not shown any conditions that subject workers to cumulative exposures in excess of general population limits. Equipment emitting gamma radiation should be presumed to be internally contaminated with alpha -emitting decay products which may be a hazard if inhaled or ingested. Before maintenance operations that require the opening of contaminated process equipment begin, the flow of gas should be stopped for four hours to allow the gamma radiation to drop to background levels. Protective equipment such as coveralls, gloves and respirators (NIOSH approved for particulates and radionuclides, or suplied-air) should be worn by personnel entering a vessel or working on contaminated process equipment to prevent skin contamination, ingestion, or inhalation of any residues containing alpha radiation. Airborne contamination may be minimized by handling scale and/or contaminated materials in a wet state. 8. EXPOSURE CONTROLS / PERSONAL PROTECTION Engineering Controls: Ensure compliance with applicable exposure limits (Section 2). Ensure adequate ventilation, especially in confined areas. Use explosion proof equipment and lighting in classified/controlled areas. Where possible, enclose operations. Use local exhaust ventilation at the site of chemical release.

Safety Keep spectators at [cast 200 feet from the touchdown area. Keep emergency service personnel at least 100 feet away, if possible. Encourage everyone working near the helicopter to wear eye protection. Remove bats or helmets or fasten chin straps (no loose hats blowing up through the rotors)! Rules of 11,r17;115 for Safe Distances: • 100 feet from helicopter to waiting ambulance • 200 feet from helicopter to crowds & pedestrians • 30() feet front the helicopter to stopped traffic • 200-400 feet from accident tictims to traffic Ground Grric e: When CareFlight arrives a the scene, only one person shoufd give 12, wind, and obstacle instructions. i'hat person should wear eye protection and they should stand with their back to the wind and anns raised over head to indicate the direction of the wind, which will usually be the opposite of the: landing direction. As the helicopter turas into the wind, and begins the final descent, the wound guide should leave to a safer area, Communications One person, the LZ coordinator, will be responsible for ail communication with the pilot.T'he LZ coordinator should monitor the radia at all times when the helicopter is running. it is Carellight's policy to monitor the 12 frcelueney far at least two minutes after departure. Every attempt will be made to contact the 12 coordinator on the frequency specified in the dispatch call. In the event that communication cannot be established on that frequency, the helicopter will monitor NLEC (National law Enforcement Channel).

Accidents involving hazardous materials require special han- dling by Firefittseuc units on the ground. The preparations for helicopters responding to these accidents also require spe- cial considerations. Tlclicopter medic:aE crews normally do not carry protective stilts or breath€rig apparatuses to protect them from hazardous materials. Upon initial radio contact, the CareFlight team must be made aware of any hazardous materials or gases in the area, Utile 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 Fire. Never assume that the crew has already been informed of the Hazniat situation. Hazardous materials of concern are toxic, poisonous, ffamma- hle, explosive, irritating, or radioactive in nature. Patients exposed to hazardous materials will require decontamination prior to air transport to avoid contamination of the crew and aircraft. Sono- radioactive materials are more dangerous than others, depending upon the type and amounts of those materials, In general, radioactive materials are difficult to ignite, but will burn, and the smoke Ls toxic. The CarcFlight team should be advised if victims may be con- taminated by radioactivity, Hazardous Materials LZ Preparation and Considerations IleIicopter landing zones must be selected to avoid possibility of compromising the safety of the CareBlil;ht team and adja- cent people and property. When explosives, poisonous gases/vapors, or chemicals in danger of exploding and burning arc ore site, helicopter landing zones must be prepared upwind, a safe distance (may be as much as one mile) from the hazardous material accident site, and never in low-lying arcas,The toxic gases or vapors may he lieavicr than air and gather in these low -tying areas. For hazardous material accidents involving radioactive materi- als, the CareFlight LZ arras€ be prepared aapwiiu4 a safe distance (may be 1/4 nate) from accident, unless there are radioactive gases (steam or smoke), and in this ease, the 12 must be at €ease one mike upwind of the accident site.

They highlight soil limitations that affect various land uses and provide information about the properties of the soils in the survey areas. Soil surveys are designed for many different users, including farmers, ranchers, foresters, agronomists, urban planners, community officials, engineers, developers, builders, and home buyers. Also, conservationists, teachers, students, and specialists in recreation, waste disposal, and pollution control can use the surveys to help them understand, protect, or enhance the environment. Various land use regulations of Federal, State, and local governments may impose special restrictions on land use or land treatment. Soil surveys identify soil properties that are used in making various land use or land treatment decisions. The information is intended to help the land users identify and reduce the effects of soil limitations on various land uses. The landowner or user is responsible for identifying and complying with existing laws and regulations. Although soil survey information can be used for general farm, local, and wider area planning, onsite investigation is needed to supplement this information in some cases. Examples include soil quality assessments (http://soils.usda.gov/sqi/) and certain conservation and engineering applications. For more detailed information, contact your local USDA Service Center (httpa/offices.sc.egov.usda.gov/locator/app? agency=nrcs) or your NRCS State Soil Scientist (http:/fsoils.usda.gov/contactl 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 sod 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 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 landfarms 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 Iandforms 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. 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. .,99 .£L .BOL ,.9Z <5L .90.f 21 a, N qN� m Ea ED .,8s ,£L .9oL Map Scala: 1:10,300 if printed onA 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 ofstrongly 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 10 Custom Soil Resource Report intensive use of small areas is planned, however, onsite investigation is needed to define and locate the soils and miscellaneous areas. 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 C 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.

This letter serves as final approval of the disposal application dated March 12, 2009. This application has been assigned U1C Facility Number 159,281 and has a maximum injected fluid volume limitation of 2,000,000 BBL from the date of this approval. This volume limit was set by a joint agreement between Chevron USA, a mineral owner within one quarter mile of the 629-1 injection well, and OXY USA. Maximum authorized surface injection pressure has been set at 800 psig based on a fracture gradient of .82 psifft. Please perform a step rate test after commencing injection to verify the ,82 psi/ft frac gradient. Only approved fluids from approved source wells can be disposed of in Class Il disposal wells. Approved fluids include produced water, used drilling fluids, used workover fluids, used stimulation fluids, and used fluids from circulation during cementing operations recovered from production, injection, and exploratory wells. The Cascade Creek 629-1 Injection well is currently permitted to inject fluids from wells listed on Form 26 (Source of Produced Water for Disposal) approved on June 5, 2009. Sources of produced water and other approved Class II fluids may be added or deleted by submitting supplemental Form 26's. A water analysis of fluids injected into the Cascade Creek 629-1 Injection well is required within one year of commencement of injection. The injected water must be analyzed for total dissolved solids, major cations and major anions. The analytical data sheet must be submitted to COGCC along with for a Form 4 (Sundry Notice) which also includes the date of initial injection.

Therefore, a water analysis of fluids injected into the Cascade Creek 629-1 Injection well will be required as a Condition of Approval on supplemental fon-n 26's when sources are added or deleted. Also, a water analysis of fluids injected into the Cascade Creek 629-1 Injection well will be required at 5 -year intervals as a Condition of Approval on Form 21's (Mechanical Integrity Test) as required in accordance with COGCC Rule 326.a.(5). The volume of all produced water, used drilling fluids, used workover fluids, used stimulation fluids, and used fluids from circulation during cementing operations recovered from production, injection, and exploratory wells injected into this well must be measured and reported on COGCC Form 7 (Monthly Reported of Operations) 45 days following the month covered by the reports. Class II fluids, other than those described above, must be approved on Form 14A (Authorization of Source of Class II Waste for Disposal) by COGCC Staff prior to injection. These fluids must be reported on Form 14 (Monthly Report of Non -Produced Water Injected). This well is not permitted for the disposal of fluids that are not Class II waste (e.g., unused stimulation fluids, amine, motor oil, solvents, field -generated sanitary waste, storm water run-off, or other fluids from unapproved sources). In accordance with COGCC Rule 326.a.(5), mechanical integrity tests (MIT's) shall be performed at 5 -year intervals on the Cascade Creek 629-1 Injection well as long as it is used for the injection of fluids. The first 5 -year period shall commence on the date the initial mechanical integrity test is performed. An MIT is also required after resetting the tubing or packer whenever the tubing or packer is disturbed during workover operations. All injection well MIT's must be witnessed by COGCC Staff.

This site is just north of the OXY "Conn Creek" Natural Gas compression / treatment facility approved as a Special Use Permit by the BOCC in 2005. Staff will present a presentation that includes photos from the site visit held on Monday, October 26, 2009. II. GENERAL PROJECT DESCRIPTION The property owner (OXY USA WTP LP) requests approval for an already constructed (and proposed expansion) centralized water treatment and storage facility on their property that is currently used to treat and store produced water used in their natural gas drilling operations in the Piceance Basin area. Generally, produced water is primarily piped into the facility from the gas producing field to be initially held in tanks to allow for separation of the residual oil and condensate from the water. The water is sent through the treatment facility and the condensate is collected in another tank battery to be then hauled off and sold at market. The primary use of the treated water will be for reuse in OXY natural gas drilling and completion operations but the water may also be reused for dust control, disposal by an on-site permitted injection well (#629-1) injection into the Wasatch formation, or discharge to the surface with approvals from CDPHE. Additionally, the owner requests the ability to provide general storage in the form of 4 (four) laydown yards (storage yards that are each up to 2.7 -acres in size) as well as storage in 2 (two) warehouse structures on the site. The Application narrative states: The laydown / storage yards will provide logistical support for operation of the water treatment facility and will be an integral part of OXY's natural gas drilling, completion, and production in the Piceance Basin area. III. REVIEW STANDARDS & STAFF COMMENTS Limited Impact Reviews are required to adequately address topics in Section 4-502(D) Land Suitability Analysis, Section 4-502(E) Impact Analysis, the general development standards found in Article VII of the Garfield County Unified Land Use Resolution of 2008 (ULUR). The following section provides a review of those standards in bold italics below followed by a Staff Response. A. Section 4-502(E) Land Suitability Analysis 1. Public Access to Site. Show historic public access to or through the site. 2 Staff Response: The property has public access via CR 213 (Conn Creek Road) which dead - ends at the property boundary where OXY's private road system begins. This site is approximately 1.5 miles north of the end of the County road which is about 5.5 miles north of the "Cowboy Chapel" at the intersection of 204 (Roan Creek) and CR213. This site has legal access. 2. Access to adjoining Roadways. Identify access to adjoining roads and site distance and intersection constraints. Staff Response: CR 213 dead -ends into the property. There are other private roads within the property that serve uses on the property which are not part of the County's road system. 3. Easements. Show all easements defining, limiting or allowing use types and access. Staff Response: The facility and the property are both owned by OXY. The site plan does not show any easements that would impact / prevent the proposed use. 4. Topography and Slope. Topography and slope determination. Staff Response: The property is located in the valley floor of Conn Creek and is surrounded by significant talus slopes which provide a canyon effect. The plan includes several existing and proposed cuts and fills to the slopes in the area. There is one significant slope cut which is shown as an expansion to an existing laydown yard at the north portion of the site. It is difficult to determine how steep the slopes were that have already been cut and leveled. However, there is a proposed expansion of the most northerly laydown area to expand about 120 feet further to the north. The rise in slope is about 30 feet which results in a 25% slope cut into Talus Slopes (Area A on images on following page). The same is true for the proposed new laydown yard on the southern portion of the site which results in a 23% slope cut (Area B on images on following page). Section 7-210(H) requires that development on slopes greater than 20% be required to demonstrate that the cut and resulting pad have been properly engineered to mitigate any slope problems. Doug Dennison (Associate Geologist formerly with Olsson & Associates) prepared a geotech report that described the areas in proximity of this site as having high to very high geologic hazards (primarily rock fall / debris flow) which will need to be considered in the design and construction of the site. It is unknown how much engineering was done for the existing development; however, both newly proposed cuts mentioned above will require 3 proper engineering to ensure their safety and performance. Staff recommends this as a condition of approval. Area A: Slopes @ 25% 1 iY Area B: Slopes @ 23% rlila ri an AN. LAypoirry,pposer 'ARP c+reNaa 4 5. Natural Features. Significant natural features on-site and off-site. Staff Response: As mentioned above, the slopes of the canyon walls are the dominant natural feature. Additionally, Conn Creek cuts through this site toward its confluence with Road Creek well below the property. Precautions (storm water / buffer distance) should be required t be addressed to minimize any impacts to this water course. 6. Drainage Features. Existing drainages and impoundments, natural and manmade. Staff Response: As mentioned, Conn Creek flows in a southerly direction through the east portion of the site. The Application contains a report from Associate Scientist, Stuart Hall, who evaluated the site for wetlands and potential impact to waterways and determined that the proposed development "will not have any impacts to wetlands or adversely affect water quality in any nearby waterways if appropriate best management practices are employed." The Section 7-203(A)(1) of the ULUR requires that there is a 35 -foot minimum setback distance from high water mark of Conn Creek for this project. The site plan will need to verify or adjust the boundaries of two of the proposed laydown yards to achieve this distance. This shall be a condition of approval. 6,7 Need to verify 35 -foot Buffer from High Water Mark irt 5 7. Water. Historic irrigation, tailwater issues, water demands, adequate water supply plan pursuant to Section 7-104. Staff Response: The purpose of the site is to properly manage the water produced from OXY's natural gas production activities on this property which is a by-product of the drilling / completion / production process. In determining how this water is used / disposed of, recent court findings now require operators to demonstrate which formation and what depth the water came from to determine if is tributary or non -tributary so that a determination can be made to its legal existence in the eyes of the State Engineers office. In this case, the gas producing wells are located in the Williams and Iles formations which appear on the non -tributary list from the Colorado Division of Water Resources as shown in Exhibit I. In this case, the gas wells producing the water which is either disposed of in the permitted injection well or treated and reused in the drilling operations in the field are non -tributary and therefore do not need a well permit from the State Engineer's Office. The Applicant intends to testify to this at the hearing. 8. Floodplain. Flood plain and flood fringe delineations. Staff Response: While the project is proposed next to Conn Creek, the 100 -year floodplain for this upper reach of Conn Creek has not been officially mapped. As a result, 100 -year floodplain regulations do not apply. The County still requires a minimum setback of 35 -feet from high water area. Several points on the eastern most laydown yard appear to exceed this distance. The proposal must be revised to respect that required setback. 9. Soils. Soils determination, percolation constraints, as applicable. Staff Response: The Application contains a soils report that points out that generally, the NRCS analysis indicate that the soils are appropriate for the proposed / existing uses of roads and shallow cut excavations; however cutbanks can occur on steeper cuts such as the one for the proposed northern laydown yard expansion pointed out above. Consideration will need to be given so that slopes are graded appropriately to minimize this cutbanking. Staff is requesting an engineering report that proposes appropriate mitigation prior to approval of a land Use Change Permit for both areas depicted above for slopes greater than 20%. 6 10. Hazards. Geologic hazards on-site, and adjacent to site. Staff Response: As mentioned above, Doug Dennison (Associate Geologist formerly with Olsson & Associates) prepared a geotech report that described the areas in proximity of this site as having high to very high geologic hazards (primarily rock fall / debris flow) which will need to be considered in the design and construction of the site. It is unknown how much engineering was done for the existing development; however, both newly proposed cuts mentioned above will require proper engineering to ensure their safety and performance. Staff recommends this as a condition of approval. 11. Natural Habitat / Wildlife. Existing flora and fauna habitat, wetlands, migration routes. Staff Comments: While this is an already development site and impacts to wildlife are unknown, the Application contains a Wildlife and Sensitive Areas Report prepared by WestWater Engineering that does discuss the wildlife in the area. No federally or state T&E species were identified at the project site. The report concluded that: ...the facility will affect site-specific native vegetation and wildlife habitat adjacent to the project site. Due to its relative small size and because the area within and around the water treatment and storage facility is already heavily developed, the project will minimally affect wildlife. The project will contribute to the overall cumulative impacts to the wildlife populations of the Roan Plateau that are experiencing gradual habitat loss, fragmentation, alteration, and displacement through increased development. The report does contain a variety of mitigation recommendations. Staff recommends the Board require the Applicant to adhere to these recommendations as conditions of approval. 12. Resource Areas. Protected or Registered Archaeological, cultural, palentological and historic resource areas. Staff Comments: The Application contains a "Class I Cultural Resource Overview" prepared by Flattops Archaeological Consultants which ultimately found that "the potential for cultural properties within the area of potential effect of the proposed development is moderate to low." Section 4-502(E) Impact Analysis. The Impact Analysis shall provide a description of the impacts that the proposed land use change may cause, based upon the standards that the proposed use must satisfy. The Impact Analysis shall include a complete description of how the applicant will 7 ensure that impacts will be mitigated and standards will be satisfied. The following information shall be included in the Impact Analysis. 1. Adjacent Property. An address list of real property adjacent to the subject property, and the mailing address for each of the property owners. Staff Comments: This was provided in the Application. 2. Adjacent Land Use. Existing use of adjacent property and neighboring properties within 1500' radius. Staff Comments: Adjacent land uses are discussed in the Application that primarily consist of remote public lands, open range country and oil and gas development. 3. Site Features. A description of site features such as streams, areas subject to flooding, lakes, high ground water areas, topography, vegetative cover, climatology, and other features that may aid in the evaluation of the proposed development. Staff Comments: The sites two primary features include 1) Conn Creek that runs through the property and could be subject to flooding in a 100 -year event and 2) steep canyon slopes that surround the site presenting a rock of rock fall and debris flow hazards during a run-off event. These are discussed above. 4. Soil Characteristics. A description of soil characteristics of the site which have a significant influence on the proposed use of the land. Staff Response: The Application contains a soils report that points out that generally, the NRCS analysis indicate that the soils are appropriate for the proposed / existing uses of roads and shallow cut excavations; however cut -banks can occur on steeper cuts such as the one for the proposed northern laydown yard expansion pointed out above. Consideration will need to be given so that slopes are graded appropriately to minimize this cut -banking. Staff is requesting an engineering report that proposes appropriate mitigation prior to approval of a land Use Change Permit for both areas depicted above for slopes greater than 20%. 5. Geology and Hazard. A description of the geologic characteristics of the area including any potential natural or man-made hazards, and a determination of what effect such factors would have on the proposed use of the land. 8 Staff Response: As mentioned above, Doug Dennison (Associate Geologist formerly with Olsson & Associates) prepared a geotech report that described the areas in proximity of this site as having high to very high geologic hazards (primarily rock fall / debris flow) which will need to be considered in the design and construction of the site. It is unknown how much engineering was done for the existing development; however, both newly proposed cuts mentioned above will require proper engineering to ensure their safety and performance. Staff recommends this as a condition of approval. 6. Effect on Existing Water Supply and Adequacy of Supply. Evaluation of the effect of the proposed land use on the capacity of the source of water supply to meet existing and future domestic and agricultural requirements and meeting the adequate water supply requirements of Section 7-104. Staff Comments: Generally, this is a facility where employees do not stay for 8 hours a day. It is visited periodically by a variety of employees who are monitoring the facility, providing maintenance, on -loading of marketable materials (condensate), and bringing in and taking out supplies and machinery for the drilling operations in the field. Staff finds that there is no need to require a permanent drinking water source and wastewater service can easily be provided by portable toilets. As mentioned above, it appears that the gas wells producing the water are located in the Williams and Iles formation and are considered non -tributary and therefore no water well permits are required by the CDWR. Staff believes there is no effect on existing water supply and that the use of the produced water is adequate. 7. Effect on Groundwater and Aquifer Recharge Areas. Evaluation of the relationship of the subject parcel to floodplains, the nature of soils and subsoils and their ability to adequately support waste disposal, the slope of the land, the effect of sewage effluents, and the pollution of surface runoff, stream flow and groundwater. Staff Comments: Due to the limited / sporadic nature of employees visiting the site, Staff finds there is no need to require an ISDS at this location. Wastewater can easily and efficiently be handled by a portable toilet. There is also no need for the drilling of a well on this property for this use and thus no impact to groundwater / recharge areas. The project does have a Storm Water Management Plan and a Spill Prevention Containment and Control Plan in place as well as secondary containment systems to protect against leakage to groundwater and surface water contamination. See the photos on the following page that illustrate these protections. Also note that these water storage tanks are located well above Conn Creek. 9 8. Traffic. Assessment of traffic impacts based upon a traffic study prepared in compliance with Section 4-502(J). Staff Comments: The Applicant prepared a Basic Traffic Analysis which ultimately yielded that background traffic equals 439 vehicle trips per day (vpd) on Conn Creek Road in 2019 and 610 vpd in 2034. The proposal generates approximately 21 average daily trips once fully constructed yielding an 8% increase to traffic on CR 213 and even less onto CR 204. These trips will not adversely impact the current road system to the point that improvements are needed. The County Road and Bridge Department reviewed the proposal and has no objections to this application with the following comments. This application is exempt from the driveway access standard as the location is past the end of the County road 213 and is access by a private road. ➢ The reduction in the traffic impact on CR 204 and CR 213 is a significant impact on the County road system and to the safety of the traveling public using these roads. 10 ➢ All vehicles hauling equipment and materials for this application shall abide by Garfield County's oversize/overweight system. All vehicles requiring oversize/overweight permits shall apply for them at Garfield County Road and Bridge Department. All vehicles applying for these permits shall have on file with Garfield County Road and Bridge Department a letter or e-mail from OXY USA stating said vehicles can obtain oversize/overweight permits under their road bond on file with Garfield County. ➢ All vehicles using CR 204 shall abide by all construction signage, this could include reduced speed limits, one lane traffic and traffic stops. This construction could continue into 2010. 9. Nuisance. Impacts on adjacent land from generation of vapor, dust, smoke, noise, glare or vibration, or other emanations. Staff Comments: Laydown / storage yards, storage, treatment and disposal of produced water at this facility do not generate a constant source of noise, dust, smoke, glare, vapor or vibration that could be determined to be defined as a nuisance to adjacent property owners. The Applicant is required to adhere to noise levels required by state law at all times as well as state requirements for VOC emissions. Staff requests that the Applicant provide copies of the approved VOC emission control permits / other applicable site permits from CDPHE prior to the issuance of a Land Use Change Permit as a condition of approval. 10. Reclamation Plan. A reclamation plan consistent with the standards in Section 7-212. Staff Comments: The Applicant states that this site will be in operation for approximately 25 years. The application does propose a reclamation plan generally listed as: ➢ All equipment and strictures 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 revegetating the site. Topsoil will be redistributed across the site and will be reseeded with an approved seed mix; and ➢ OXY will monitor the site to ensure that 70% of the pre-existing vegetation is achieved. 11 Staff finds this reclamation plan acceptable with the following additional conditions prior to the issuance of the Land Use Change Permit: 1) All retaining walls made of wood, stone, vegetation or other materials that blend with the natural landscape shall be used to reduce the steepness of cut slopes and to provide planting pockets conducive to revegetation. 2) The Applicant shall meet with the County Vegetation Manager prior to issuance of a Land Use Change Permit so that every area disturbed shall have a time line approved for the reclamation of the site approved by the County and a security shall be provided to Garfield County in an amount of $2,500 per disturbed acre to be reclaimed prior to the issuance of a Land Use Change Permit. 11. Areas Subject to Wildfire Hazards (Section 7-209). Staff Comments: The site is not located in an area of known to be a wildfire hazard area. The county mapping shows the area to be in a moderate to low hazard area as it is down on the valley floor of Conn Creek. IV. SUMMARY COMMENTS The Applicant self reported the existence of this project on their property to County Planning Staff in the fall of 2009 and indicated they would be submitting an application in order to obtain the proper land use permits. It is unfortunate that the project is already constructed as that makes it difficult to properly assess land use impacts such as impacts to wildlife, surface water, and site engineering. The Applicant did submit a thorough application that has addressed all of the required standards and the resulting review found that the project concerns include: 1) Two proposed laydown yard sites / expansion areas are in slopes over 20% requiring proper engineering and / or avidance; 2) Reclamation plan needs to be approved by County and a bond tendered to ensure it takes place; 3) Wildlife recommendations need to be adhered to; 4) Stream setbacks from Conn Creek need to be verified and established on the site plan; and 5) Water usage is legally adequate so as it used for oil and gas purposes only. 12 V. SUGGESTED FINDINGS Should the BOCC decide to approve the request for MATERIAL HANDLING OF NATURAL RESOURCES (INCLUDING WATER STORAGE AND TREATMENT" and "INJECTION WELL"); and "STORAGE: SUPPLIES, MACHINARY, EQUIPMENT, OR PRODUCTS" through this Limited Impact Review, Staff suggests the BOCC make the following findings: 1.

Noxious weeds and invasive plant species have now invaded many habitats due to construction and ground clearing of native vegetation. Woodlands, sagebrush and native grasses are key food sources for elk and mule and provide nesting and foraging habitat for a variety of migratory birds and small mammals. Reclamation plans should include efforts to restore these vegetation communities, particularly the sagebrush community for sage -obligate species. Reclamation recommendations include the following: 1. Seeding of native Wyoming and big basin sagebrush should be added to the re -vegetation plan. Local, ecologically adapted sagebrush seed from the existing sagebrush vegetation near the project area should be used in reclamation. 2. Ongoing control of noxious and invasive weeds is recommended as an additional method to maintain native vegetation communities and favorable wildlife habitats. An WestWater Engineering Page 15 of 20 May 2009 "Integrated Vegetation and Weed Management Plan" is provided for this project in a separate report. 3. Mitigation for wetland impacts will be provided in accordance with Army Corp of Engineers standards. 7.2 Planning for Sensitive Time Periods and Areas 7.2.1 Male Deer and Elk Disturbance associated with construction equipment and personnel may cause elk and mule deer to select habitats in more secluded areas away from the water treatment and storage facility. „Ay construction and/or o+erational activities during the winter months will impact deer and elk winter ran t - ... ,. a+ s e+ s i P OW "NDIS". According to the Colorado Oil and Gas Conservation Commission's amended rules, effective April 1, 2009, elk winter range is excluded from the rules as sensitive wildlife habitat. Deer critical winter range and deer severe winter range are included in the new 2009 rules, neither of which are located within the project area (COGCC 2009). 7.2.2 Migratory Birds In order to comply with the Migratory Bird Treaty Act by showing a good faith effort to reduce potential impacts on nesting birds, brush/tree clearing should take place outside of the nesting seasons. Nesting season is generally considered between May 15 and July 31 in this area for most species. June 1 to July 15 is the peak period when most incubation and brood rearing takes place. If brush/tree clearing can occur prior to May 1, most affected birds will relocate to alternate nesting sites. After mid-to-late July, most fledging has occurred and brush/tree clearing impacts would be minimized. Pinyon Jays are an exception to typical nesting periods in this area and are known as an early nester. Records show nests with eggs as early as March 23. Often young birds have fledged by May 15. Because Pinyon Jay habitat makes up a lesser amount of the project site, the pre -May 1 vegetation clearing recommendation is acceptable and adequate to avoid destruction of active migratory bird nests. 7.2.3 Greater Sage -Grouse In order to reduce the likelihood that sage -grouse populations decline near the project area, effective natural gas pre -development planning and post -development practices offer the best prospect for mitigating adverse affects to sage -grouse populatioris. Planning development with projects engineered to avoid, minimize, and mitigate affects of natural gas development are approaches that result in the most favorable mitigation outcomes. No affects to sage -grouse are expected to occur as a result of the facility construction, operation, or maintenance. No specific planning is recommended in regards for Greater Sage -grouse. WestWater Engineering Page 16 of 20 May 2009 7.2.4 Raptors Activities associated with the water treatment and storage facility have the potential to impact raptor populations. In order to reduce the potential affects to nesting raptors, it will be important that the project proponent schedule construction activities such that they do not interfere with breeding, nesting, and brood rearing activities. CDOW's (Craig 2002 and Klute 2008) recommended raptor nest site avoidance standards for the species observed in this survey are summarized below (Table 7). If the project cannot be completed prior to, or after, the next nesting season, known nest sites should be re -inventoried by qualified biologists. If any birds are found behaving in a manner consistent with nesting, every effort should be made to apply the timing limitation and buffer distance stipulations. Table 7.

Keep activity to a minimum unng reeseason. 7.3 Other Mitigation Practices 7.3.1. Erosion Efforts to control soil erosion within the project area should be implemented. Disturbed soils within the project area are susceptible to erosion and downstream water quality could be negatively affected by increased soil erosion. In addition to stormwater management around the project site, other current factors (noxious weeds, livestock grazing, other natural gas development) affecting soil erosion should be managed and remedial measures implemented. Prior to any construction which involves potential stream crossings, appropriate consultation with the U.S. Army Corps of Engineers (ACOE) is recommended. To protect the integrity of the stream ecosystems and the associated riparian habitat within the project area, precautions should be taken when crossing or intersecting the drainages identified. Implementation of a storm water management plan and standard best management practices, including adequate barriers and filtration methods, should be used to prevent and reduce soil from eroding into streams and riparian areas. This may include the installation of check dams along small ephemeral drainages and vegetation restoration. WestWater Engineering Page 17 of 20 May 2009 7.3.2 , Black Bears Black bears will likely move through the general project area and could be attracted to human- related food sources (garbage, pet foods and barbeque grills). In order to prevent human injury and/or the un-wanted removal, injury, or destruction of bears, it is recommended thatfood_and garbage storage and removal be done in a timely and secure manner so . :toot-habitifate bears to the human activities oA"the pro3ect.
