Oxy monitors and treats noxious weeds seasonally typically with bareground treatments in the early spring followed by hand -spray applications upon detection of noxious weeds. Oxy tracks noxious weed treatment in compliance with Oxy's Noxious Weed Management Plan. Federally threatened, endangered, proposed, and candidate Species No federally threatened, endangered, proposed, candidate or sensitive species occur in the project area. There are no anticipated impacts to this category of species. General Wildlife Temporary increases in human activity at the site may discourage use by some wildlife species; however, most species found in the project vicinity are acclimated to human presence and may temporarily alter their behavior patterns during active construction. The project would result in about 0.75 acres of regrading on the eastern edge of the site in existing minimally disturbed areas for purposes of improving sediment control. This area is low sagebrush vegetation on moderate slopes, which is poor shelter and forage habitat. There is little risk for wildlife, including deer, to pass fRD Resources Corporation into the pond area or become trapped in the pond; the proposed eight -foot fence with skirting would prevent both ungulates and small mammals from passing into the produced water storage impoundment. Oxy's wildlife policy states that Oxy employees or contractors will not harm or harass wildlife. Migratory Birds Clearing, grubbing, and increased human activity all have potential temporary and permanent impacts to migratory birds. No new surface disturbance in nesting areas is anticipated to result from proposed activities at Pond 10; therefore no permanent impacts to migratory birds are anticipated. Increased human activity may temporarily discourage use of the project area by migratory birds; however this impact would be limited to the construction period. Following construction activities, birds are anticipated to resume their normal pattern of use and activity. Bird -specific netting would be installed over the pond to preclude entry by migratory birds. (COGCC 2014b). Radiation and Other Hazards No radiation or hazardous materials, including liquids would be stored at the site. Recommendations • No wildlife or raptors were observed during the site visit in April 2013. Based on this site review, it is unlikely that raptors would be disturbed by construction at the site due to lack of nearby habitat. However, ERO understands that a follow-up site visit may be necessary in April or May 2014. • ERO recommends additional weed surveys and treatment be conducted prior to work at the site, in compliance with Oxy's Noxious Weed Management Plan. • New temporary disturbance areas should be reseeded with an appropriate seed mix similar to the mix shown in Table 5. Oxy will utilize the seeding mix identified in the SWMP. • Activities would adhere to Oxy policies, including traffic regulations and posted speed limits (25 mph in project area). Table 5.

Title 35, Article 5.5) ("Act"), Colorado Oil and Gas Conservation Act, local, and federal noxious weed management requirements, such as Garfield County Planning Department and the Bureau of Land Management (BLM). The Plan also covers special best management practices (BMP's) for management of noxious weeds in two designated State Natural Areas (SNA's) located on Oxy property. The Act requires that "noxious weeds" be managed on private and public lands. The Act further declares that control of noxious weeds should use methods that are least damaging to the environment but also practicable and economically reasonable. The state requires management of noxious weeds included on one of three lists (see Appendix A): List A — designated for statewide eradication; List B — managed to prevent further spread and, for selected species, designated for eradication in large areas; and List C — of more localized concern, but for which the state will provide education, research, and biological control assistance to jurisdictions that choose to manage the species. Oxy owns/leases and operates certain mineral properties in the Piceance basin, located in Western Colorado. This Plan is intended to manage Oxy's oil and gas operational areas in order to comply with all local, state and federal noxious weed management requirements including Garfield County, Colorado Oil and Gas Conservation Commission (COGCC), and the BLM. Compliance Statements Oxy will manage all noxious weeds, as defined by the Act, the guidelines in the Garfield County Noxious Weed Management Plan, the local BLM Pesticide Use Plan (PUP), any other approved noxious weed management conditions of approval (COA's) issued by a land management agency in existing surface disturbed areas managed by Oxy as well as newly disturbed project areas. Some noxious weed management COA's may be identified by a biological consultant at the time of project specific inventories. The term, "disturbed area" includes all well pads, access roads, easements, pipelines, and associated support facilities such as compressor stations, water management facilities, and other areas disturbed by project activities. Disturbed areas also include soil stockpiles, earthen berms and other erosion control BMP's that require ground disturbance for installation and maintenance. Oxy will comply with COGCC noxious weed management 1000 Series rules, which requires Oxy to keep all disturbed areas free of noxious weeds. Cascade Creek Noxious Weed Management Plan Page 2 Oxy will report all State List A and List B noxious weed populations inventoried and treated and any other species identified by Garfield County for eradication upon discovery to the appropriate County designee. The Colorado Natural Areas Program (CNAP), which manages the designated SNA's have provided Oxy with recommended noxious weed management BMP's that will aide in protecting native plant species. The recommended BMP's will be applied where feasible. Local Contacts The local contact for Oxy's Plan include the Regulatory Advisor, who serves as Oxy's noxious weed management coordinator and manages the noxious weed contractors. - Regulatory Advisor — Daniel I. Padilla, 970.263.3637 Garfield County's Vegetation Management contact number is 970.625.8601. Addition contact information is listed in local contacts section of the Plan. Operating Area Oxy manages active and inactive leases associated with natural gas exploration in the following areas of Garfield County: • Cascade Creek Operating Area, which is separated into three primary fields; o Valley o Mesa o Logan Wash; this area contains two SNA's: • Mount Callahan SNA • Mount Callahan Saddle SNA Oxy operates on split estate, where surface lands may be wholly federal (BLM) and minerals wholly fee owned and vice versa. Land Use Objectives Oxy conducts natural gas exploration and production activities on fee and federal lease holdings in Western Colorado. Land uses and types of facilities to be developed include access roads, pipelines, well pads, compressor stations, staging/storage areas for equipment and supplies, and other associated natural gas development activities. Some of the developments are short-term temporary disturbances, such as staging areas and pipelines, while the access roads, well pads, and other support facilities remain in active use for an estimated 20-30 years. Cascade Creek Noxious Weed Management Plan Page 3 Weed Management Objectives and Implementation Strategies The following are the overall objectives of the Plan: • Inventory and monitor existing or new noxious weed infestations using Global Positioning System (GPS) equipment or other mapping techniques. Inventories shall occur at least annually; • Prevent new infestations of noxious weeds; • Utilize state certified contractors to implement an Integrated Weed Management (IWM) protocol as recommended by the state or Garfield County Noxious Weed Management plan to control or manage noxious weed populations; • Maintain a noxious weed inventory, herbicide application and mapping records; • Restore disturbed areas to protect native plant ecosystems and watersheds from degradation by noxious weeds. Specific actions to be taken to meet these objectives include: • Bareground treatments will occur at existing facilities at the start of the spring season, prior to noxious weed emergence to reduce the emergence potential of noxious weeds. • Annual monitoring will occur at existing and new facilities, specifically looking for noxious weeds. If noxious weeds are identified, they will be mapped, treated, and the treatment event will be logged, • All treatment events will be logged by the noxious weed treating contractor using a Pesticide Application Record (PAR). See Appendix B for an example of what information should be collected; the contractor may choose their own format. The PAR will be use to report noxious weed management activities to federal land managing agencies. In addition to completing the PAR, the noxious weed contractor will complete Oxy's noxious weed tracking form, see Appendix C. • Completion of the PAR and Oxy's tracking form will serve as documentation of noxious weed management activities. • Where feasible implement area specific noxious weed management BMP's in the two designated state management areas, see Appendix E. Inventory and Monitoring Before a new site is developed and when practical, Oxy will inventory the site and adjacent areas for noxious weeds, including access roads and other probable weed ingress routes. If development activities are started in the winter months or when noxious weeds cannot be identified, the new disturbance area will be inventoried the next growing season. Noxious weed locations (List A and List B species) will be collected with a GPS unit or mapped in relation to the facility or landmark. Any noxious weed infestations found will be treated before site disturbance, if timing is appropriate. If the timing is not appropriate for noxious weed treatment, activities may proceed and the weeds will be monitored and treated during the appropriate season. Weeds on adjacent properties may be treated as appropriate with permission of the landowner. Populations of Colorado or County List A and List B species (see Appendix A) will be reported to the County Weed Manager. On federal lands or for federal projects, a Noxious Weed Inventory record will be Cascade Creek Noxious Weed Management Plan Page 4 completed each time a List A or B weed infestation is inventoried (with the exception of redstem filaree and quackgrass), and the populations will be reported. Monitoring will be conducted at least annually, early in the growing season, by Oxy staff or contractors, and in coordination with BLM staff on federal lands. For most of Oxy's operation areas, monitoring will occur between May and July. All previously treated noxious weed sites will be monitored for regrowth and scheduled for re -treatment as necessary. All disturbed areas under Oxy management will also be monitored to ensure there are no new weed infestations. Prevention The purpose of prevention measures is to preclude the introduction of new or existing noxious weeds from the project area to un -infested areas or from adjacent land into the project area. Construction Prevention Measures Construction equipment entering project areas (backhoes, trackhoes, dozers, blades, rollers, lowboys, equipment trailers, etc.) will be power washed or otherwise cleaned. "Equipment" is defined as any earth moving and any other machinery, trucks or vehicles, trailers and tools. On Federal property, equipment may be inspected by BLM or Forest Service (FS) personnel. Pickup trucks, SUVs, vans, water trucks, and pipe trucks should also be clean but do not require inspection prior to entering federal lands. Where required, track pads, gravel beds or rumble strips will be installed at ingress/egress points to the site to limit weed seed from entering or leaving the site. Soils from infested areas of the project site will not be moved off site, but will be stockpiled and treated for weeds as necessary. If infested soils are moved off site, they will be kept on Oxy -managed property, monitored, and treated as necessary. Stockpiled soils will be monitored and treated to control noxious weeds. All purchased products used in development and reclamation of a site will be inspected or certified as weed -free whenever possible, including soils, rock and gravel, seeds, mulch and erosion control products. Operational Prevention Measures Existing facilities such as well pads, valve/meter sites, and compressor stations that require work areas to be free of vegetation shall have bareground treatments at the start of spring. Existing facilities such as access roads and reclaimed pipeline right-of-ways shall be monitored through the growing season for noxious weeds and noxious weeds identified will be treated. Revegetation The goal of reclamation and revegetation of a site after disturbance is timely establishment of a desirable native plant community and prevention of noxious weed infestation. Elements of successful revegetation include the use of topsoil that was set aside during construction and kept weed -free; reseeding with appropriate species to establish plant cover, and stabilization of the soil surface with the appropriate mulches, tackifiers, and erosion control products as needed. Cascade Greek Noxious Weed Management Plan Page 5 Plans for revegetation and reclamation of disturbed areas are site-specific, and will include a plant list, method of seeding, how seeding success will be determined and how the revegetated area will be monitored. Oxy will rely on existing surface use agreements, revegetation plan, or Stormwater Management Plan, which has a recommended seed mix. BLM and FS seed mixes are compiled on a site-specific basis, according to elevation and existing vegetation community on the site. Non-native, non-persistent sterile grasses may be used to provide ground cover for soil stabilization and weed suppression during temporary reclamation on both private and federal land. See Appendix D for a sample Oxy Revegetation and Reclamation Plan. Certified weed seed free straw, hay, mulch, seed or other materials will be used for soil stabilization and/or revegetation purposes (Colorado Department of Agriculture certified inspector to State standards). Seed tags will be available for inspection upon request of the Inspector. Topsoil that is stock piled for more than one year will be seeded according to above standards at the earliest practical time to reduce the possibility of noxious weed establishment. Revegetation efforts will be monitored annually until successful establishment of desirable or intentionally planted seed or plants is confirmed. Noxious weeds found in revegetation will be documented, and managed per guidelines in this Weed Management Plan. Control and Management The noxious weed contractor will follow the guidelines identified in the Noxious Weed Management Plan developed by the Colorado Department of Agriculture and the Garfield County Noxious Weed Management Plan developed by the Garfield County Vegetation Management department to identify, treat, and control noxious weeds. Treatments will include herbicide, cultural, mechanical, revegetation, and biological control alone or in combination as necessary for efficient weed control. On federal lands, control and management methods (including herbicide use) will be verified and approved with the appropriate land management agency representatives. Noxious weed management activities on federal lands will comply with the BLM or other land management agencies PUP. Annual reporting to the BLM or other land management agency will be completed as prescribed in the PUP by the noxious weed contractor. The accompanying treatment tables describe the management methods, rates, and timing of control measures for specific targeted weeds (see Table 1 and Table 2). Treatment application records will be retained by Oxy and available for inspection by agency personnel listed in the contacts section below.

Upon termination of the development and production activities, the facility will be reclaimed, as outlined below: • All equipment and structures will be removed. • OXY will remove all safety and storm water BMPs, and other surface objects from the premises. • OXY will restore the site to pre -facility conditions by re -contouring and re -vegetating the site. Top soil will be redistributed across the site and will be reseeded with an approved seed mix (see attached seed mix recommendation). • OXY will monitor the site to ensure that 70 percent of the pre-existing vegetation is achieved, per the requirements of the area wide CDPHE Stormwater Permit for Cascade Creek and Collbran Developments. Seedbed Preparation and Slope Reconstruction: Cut and fill slopes will be backfilled and re-contoured to a slope of 3:1 — 2.5:1 or less in instances where necessary to match the existing natural contours. Following final contouring, all backfilled or ripped surfaces will be covered evenly with topsoil. Re -contouring should form a complex slope with heavy pocking. In areas with slope greater than 3 percent, imprinting of the seed bed is recommended. Final seedbed prep will consist of scarifying/imprinting the topsoil prior to seeding. Imprinting can be in the form of dozer tracks or furrows perpendicular to the direction of slope. When hydro -seeding or mulching, imprinting should be clone prior to seeding, unless the mulch is to be crimped into the soil surface. If broadcast seeding and harrowing, imprinting will be done as part of the harrowing. Furrowing can be done by several methods, the most simple of which is to drill seed perpendicular to the direction of slope in a prepared bed. Other simple imprinting methods include deep hand raking and harrowing, always perpendicular to the direction of slope. All compacted areas will be ripped to depth of 18" with max furrow spacing of 2'. Where practicable, ripping will be conducted in two passes at perpendicular direction. Topsoil: Following final contouring, all backfilled or ripped surfaces will be covered evenly with topsoil. The topsoil in the cut slope on the back of the pad will be heavily pocked using the excavator bucket to form an uneven soil surface complex which will aid in revegetation and help with slope stabilization. The fill slope, and remaining disturbed, and reclaimed areas will be track walked to aid in revegetation and slope stabilization. In areas that may not have been disturbed during the reclamation process or areas of suspected compaction that will be reseeded, measures will be taken to loosen and spread the topsoil. These measures may include scarifying the soil by racking or harrowing the soil. Seed Mix: Seed mix used for reclamation will be taken from the attached seed mixtures. Seeding Procedures: For best results and success, the recommended grass mixture reseeding should be done in late autumn in order to take advantage of natural precipitation for the region. The reseeding rate should be doubled for broadcast application. Preferred seeding method is Cascade Creek Noxious Weed Management Plan Page 19 multiple seed bin rangeland drill with no soil preparation other than simple grading to slope and imprinting and waterbars, where applicable. Alternative seeding methods include, but are not limited to: • No -till -drill (no soil preparation required); • harrow with just enough soil moisture to create a rough surface, broadcast seed and reharrow, preferably at a 90 degree angle to the first harrow; • hydro -seeding (most economical in terms of seed cost); and • hand raking and broadcast followed by re -raking at a 90 degree angle to the first raking. • These are not the only means of replanting the site. However, these methods have been observed to be effective in similar landscapes. The prepared soils will be seeded (weather permitting) no more than 24 hours following completion of final seedbed preparation. The seeding will be conducted by means of drilling the prescribed seed at prescribed seeding rate. The seed will be drilled with a common range drill at a depth of 0.25 -- 0.5" beneath the soil surface. The seed will be drilled horizontally across the pad faces and perpendicular to the track walking when possible. When slope gradient less than 2.5:1 exists and drilling is not possible from a mechanical and safety standpoint the soils will be broadcast seeded at twice the prescribed amount. The reseeding will be monitored and reseeded as appropriate until the reclamation standards detailed above are met. Cascade Creek Noxious Weed Management Plan Page 20 Appendix E Noxious Weed Management Protocols for Areas within the State Natural Areas Cascade Creek Noxious Weed Management Plan Page 21 In addition to Oxy's noxious weed management objectives for its Piceance Basin operations, Oxy has worked with the Colorado Natural Areas Program (CNAP) to develop additional guidance documents to complement Oxy's Noxious Weed Management Plan. The guidance documents provide detailed recommendations to address noxious weeds identified within the designated State Natural Areas. Additional measures that Oxy will take when practicable to take to manage noxious weeds includes: o Conduct pre -disturbance noxious weed inventories for proposed new activities, including access roads, pipelines, well pads, communications towers, or other oil and gas related facilities requiring ground disturbance. o Construction vehicles that will be used in the State Natural Areas will be power - washed to remove mud and debris from tires and the vehicle's undercarriage before use on the site to reduce the spread of noxious weeds from other areas. o Minimize to the extent possible oil and gas disturbance activities to. soil and native vegetation as much as possible. o Reclaim temporary construction areas as soon as practical with native seed mix or where appropriate a sterile hybrid. o Restrict motorized travel to designated access roads and oil and gas facilities. o Use CNAP prescribed native seed mix for revegetation efforts of disturbed areas ready for reclamation. o Protect cut and fil slopes against erosion with the use of water bars, lateral furrow or other appropriate stormwater best management control measures. o Conduct multiple visits to post disturbance areas during the growing season to monitor and treat as needed for noxious weeds. o Where feasible, follow CNAP's recommended Noxious Weed Treatment Methods, which include prioritizing noxious weed treatment activities by focusing on List A and B noxious weeds and associated treatment, utilizing integrated treatment techniques (limiting chemical controls, increasing mechanical controls, and utilizing qualified personnel familiar with the area to treat noxious weeds. o Conduct mapping and monitoring of noxious weeds treatment activities. To the extent practicable, Oxy will preplan all proposed oil and gas activities within the State Natural Areas to ensure that only areas required to conduct safe oil and gas operations are developed and utilized, which would include sizing of infrastructure in anticipation of future development, centralizing wells and associated production units and tanks, and consulting with CNAP for additional best management practices associated with development activities. For existing facilities, Oxy will post and maintain signage that reaffirms only authorized personnel are allowed in the area and that off -ROW excursions are prohibited. Attached are CNAP specific noxious weed management guidance documents.

Produced Nontributary Ground Water Rules 2 CCR 402-17 2 17.5 Process for Obtaining a Determination of Nontributary Ground Water Any person may seek to amend these Rules, through applicable rulemaking procedures, to identify areas within the State of Colorado where the State Engineer shall regard Produced Water to be nontributary, or to amend, based on factual information not presented at the time of adoption, the Rules to exclude areas previously determined to be nontributary pursuant to these Rules or any amendment thereof. An amendment excluding areas previously determined to be nontributary will not invalidate any existing permits issued pursuant to these Rules or otherwise cause the State Engineer to change his administration of wells in existence prior to such amendment. As an alternative to requesting a rulemaking proceeding, an Operator may obtain a determination regarding the nontributary nature of Produced Water through an adjudicatory proceeding before the State Engineer. Any such request for a nontributary determination must be submitted pursuant to the procedures set forth in this Rule 17.5. These Rules do not preclude any Operator from obtaining a determination regarding the nontributary nature of Produced Water, for the purpose of section 37-90-137(7), C.R.S., through an appropriate proceeding before the Water Court. A. Submittal of Petition for a Determination of Nontributary Ground Water An Operator or group of Operators seeking a nontributary determination for Produced Water withdrawn from an existing well or group of wells, or for a well or wells to be constructed in one or more geologic formations within a geographically delineated area ("Applicant") shall file a petition in the form of a letter and accompanying professional report to the State Engineer. The petition shall at a minimum contain the following information: 1. Information indicating whether the ground water will be withdrawn to facilitate or permit the mining of minerals, or withdrawn for purposes other than the mining of minerals. 2. Information indicating whether the Applicant is seeking a nontributary determination for a single well, group of wells, or for all wells, whether such wells have been constructed or are proposed to be constructed in one or more geologic formations within a geographically delineated area, 3. Information sufficient to demonstrate, through analytic or numeric modeling, that the depletions that result from pumping at the location of the well, wells, or at any well constructed, or proposed to be constructed in one or more geologic formations within a geographically delineated area, meet the nontributary standard. In lieu of ground water modeling, the Applicant may provide geologic, hydrologic, and other information sufficient to demonstrate that each subject geologic formation at the well location or within the geographically delineated area is hydraulically disconnected from all surface streams such that there will be no depletions to any surface stream as a result of pumping. B. Notice and Comment 1. Concurrent with submission of the petition to the State Engineer, the Applicant shall file notice of the petition. The notice shall be sent to all parties on the Produced Nontributary Ground Water Notification List for the water division in Produced Nontributary Ground Water Rules 2 CCR 402-17 3 which the subject ground water is located and the primary newspapers in circulation in the affected watersheds. 2. The State Engineer shall establish a Produced Nontributary Ground Water Notification List for each water division within the State of Colorado for the purposes of ensuring that water users within each water division receive adequate notice of proceedings held pursuant to these Rules. In order to establish such notification list, the State Engineer shall, immediately upon effect of these Rules, and in January of each year thereafter, cause to have published in the water court resume for each water division an invitation to be included on such notification list for the applicable water division. Persons on the Produced Nontributary Ground Water Notification List shall be provided notice required pursuant to these Rules by either first-class mail, or, if a person so elects, by electronic mail. 3. The State Engineer shall allow 30 days for any person to respond to the petition. A person may respond to the petition by submitting written comments or by requesting that the matter be referred for hearing on the petition. The person must state the basis for such a request in sufficient detail to allow the State Engineer to determine whether a hearing is appropriate prior to an Initial Determination. The Applicant or the staff of the State Engineer may also refer the matter for hearing on the petition. If the State Engineer determines a hearing is appropriate, he shall schedule a hearing pursuant to the procedures described below. The State Engineer may submit the matter to a designated Hearing Officer at his discretion. C. Initial Determination 1. If no person requests a hearing, the staff of the State Engineer shall evaluate the petition and any written comments, and produce an Initial Determination with respect to whether water withdrawn from an existing well or wells proposed to be constructed in one or more geologic formations within a geographically delineated area is nontributary. The Initial Determination may find that water from only certain wells or certain locations is nontributary. 2. The staff of the State Engineer shall provide a copy of its Initial Determination to the Applicant, any person who submitted written comments, and any person who requested a copy of the Initial Determination. If no person objects to the Initial Determination within 30 days, the staff of the State Engineer will submit its initial determination to the State Engineer for review and certification as a Final Decision, as described below. D. Hearing 1. If any person objects to the Initial Determination, or if the State Engineer has determined a hearing is appropriate before an Initial Determination, the matter will be set for an adjudicatory hearing before the State Engineer, The person objecting must state in detail the basis for such an objection to the Initial Determination. Produced Nontributary Ground Water Rules 2 CCR 402-17 4 2. The hearing shall be conducted pursuant to the Division of Water Resources Procedural Regulations, 2 CCR 402-5, and applicable provisions of the State Administrative Procedure Act. The Applicant shall provide notice of the hearing to any person who responded to the petition. 3. For purposes of the hearing, the Applicant shall be considered the party requesting the hearing and the proponent of the order, and shall have the initial burden of proof. Any person who responded to the petition may participate as a party to the hearing. The staff of the State Engineer may participate as a party. 4. The State Engineer may consider the Initial Determination of the staff of the State Engineer as evidence; however, the hearing will be de novo, based upon the evidence presented at the hearing. E. Final Decision If no hearing is held, the Initial Determination shall become the Final Decision of the State Engineer ("Final Decision") with respect to the Applicant's petition. If there has been a hearing on the petition, the decision of the State Engineer shall become the Final Decision of the State Engineer pursuant to procedures set forth in the Division of Water Resources Procedural Regulations, 2 CCR 402-5, and applicable provisions of the State Administrative Procedure Act. F. Effect of Final Decision 1. The State Engineer shall rely upon the Final Decision to evaluate well permit applications submitted pursuant to section 37-90-137(7), C.R.S., where an operator is withdrawing nontributary ground water to facilitate the mining of minerals, and where the nontributary ground water being removed will be beneficially used. 2. The State Engineer shall rely upon the Final Decision to authorize the withdrawal of nontributary ground water to facilitate the mining of minerals without requiring a well permit, pursuant to section 37-90-137(7), C.R.S., where the nontributary ground water being removed will not be beneficially used. 3. Where a Final Decision is applicable to all wells to be constructed within a geographically delineated area, the State Engineer shall rely upon the Final Decision to evaluate all wells constructed within that area for the purposes set forth in the preceding paragraphs. 17.6 Engineering and Scientific Methodologies and Standards A. An Applicant shall comply with the engineering and scientific methodologies and standards described in Rule 17.6 of these Rules when submitting a petition for determination of nontributary groundwater made pursuant to Rule 17.5 of these Rules. B. Conceptual Model For any petition for determination of nontributary groundwater submitted pursuant to Rule 17.5 of these Rules, an Applicant shall include a conceptual model of the geologic Produced Nontributary Ground Water Rules 2 CCR 402-17 5 and hydrogeologic characteristics of the relevant area, formation or basin under consideration. The conceptual model shall adequately represent the known geologic and hydrogeologic characteristics of the ground water system. At a minimum, the conceptual model shall define the hydrostratigraphic units along with any known characteristics and boundary conditions. The conceptual model will determine whether numerical or analytical modeling, or alternative methodologies are appropriate for evaluating the petition for a determination of nontributary ground water. For numerical modeling, the conceptual model shall establish the preliminary water budget of the system, which should include sources of water, flow directions, and discharge or exit points. C. Ground Water Modeling 1. An Applicant may use mathematical ground water modeling simulating the ground water system through equations that describe the heads or flows with representative boundary conditions to demonstrate that the withdrawal of produced ground water that is, or is presumed to be, in hydraulic connection with the surface water system is nontributary, as defined at section 37-90-103(10.5), C.R.S. 2. Any ground water model used to demonstrate that the withdrawal of produced ground water that is, or is presumed to be, in hydraulic connection with the surface water system is nontributary shall comply with the protocol for development and use of a mathematical ground water model as generally agreed upon by technical experts in the water resources discipline. Many analytical and numerical models are available that may be found acceptable for use in the evaluation of an Application. However, the Applicant must demonstrate the model's suitability and applicability to determining that the ground water is nontributary. The Applicant should contact the State Engineer's Office regarding the use of models since certain models will have more or less credibility with ground water modeling experts. 3. For situations in which the hydrologic system is under confined or semi -confined conditions, model calculations shall utilize a storativity (storage coefficient). A specific yield value may be used in the calculations where water table (unconfined) conditions exist. 4. All data files used in a numerical or analytical ground water model shall be provided in an electronic format deemed acceptable to the State Engineer's Office. All data files shall include the model input files as well as any supporting data used in the development of the model input files. Any GIS shape files used in the development of the model shall also accompany submittal of the model. 5. Documentation to explain the context and methodology of all ground water modeling shall accompany the Professional Report as described in Rule 17.6.E. It is incumbent upon the Applicant to demonstrate to the satisfaction of the State Engineer's Office that the model code and input data are suitable and applicable for determining that the produced ground water is nontributary. Proprietary information and data need not be disclosed by an Applicant beyond that which is Produced Nontributary Ground Water Rules 2 CCR 402-17 6 deemed necessary by the State Engineer's Office to evaluate the model and verify mode! input parameters. 6. Any party objecting to a petition for an adjudicatory proceeding or objecting to an Initial Determination, as specified in Rule 17.5, may obtain all supporting information relied upon by an Applicant in developing any ground water modeling, or alternative methodologies. The Applicant's obligation to disclose such information arises upon request of any party and, to the extent that the Applicant deems and the State Engineer finds any such information sensitive, confidential, or proprietary, the parties and State Engineer shall agree to hold such information confidential and protect it from public dissemination under appropriate terms and conditions. D. Alternative Methodology 1. Geologic conditions at a site may effectively isolate the mineral -bearing production zones from the surface water system. An alternative method may be utilized to demonstrate that ground water produced in conjunction with the mining of minerals from the potential and existing production zones is nontributary. Alternative methodologies are intended to demonstrate that the production zones are disconnected from the surface water system by a lithologic discontinuity or structural separation between the production zone and its outcrop equivalent. 2. The criteria for demonstrating isolation of an existing or potential production zone from the surface water system may include both direct and indirect physical evidence such as that obtained from drilling, borehole geophysical logging, surface seismic and geophysical surveys, drill stem and pump tests, geochemical analyses and surface and subsurface mapping. Geologic and geophysical maps and cross sections shall be based on actual evidence obtained from drilling, geophysical and/or seismic surveys or other verifiable geotechnical investigations. Location, seismic and geophysical survey data, including GIS data, shall be submitted in a paper and/or electronic format deemed acceptable by the State Engineer's Office. 3. Published professional reports, investigations, or technical papers may be provided as a source of factual evidence in support of a petition. 4. Petrophysics, hydrogeologic data and water chemistry may be used to support the conclusions of a petition. Samples of water and gas, or other media to be subjected to chemical or isotopic analysis, shall be collected, handled and analyzed to ensure that the results are consistent with the intended use of the data. A detailed description of the sample collection procedures and analytical methods shall be submitted to the State Engineer's Office upon request. Laboratory data shall be submitted in a format deemed acceptable by the State Engineer's Office. 5. Copies of supporting evidence shall be provided to the State Engineer's Office upon request. Such evidence may include, but is not limited to, geophysical logs and surveys, pump and drill stem test data, lithologic descriptions or other Produced Nontributary Ground Water Rules 2 CCR 402-17 7 physical or hydrologic analyses and water quality/chemistry analyses on which the Applicant has relied to support a petition. Proprietary information and data need not be disclosed by an applicant beyond that which is deemed necessary by the State Engineer's Office to evaluate the petition and demonstrate that the data on which the Applicant's conclusions are based is valid. B. Any party objecting to a petition for an adjudicatory proceeding or objecting to an Initial Determination, as specified in Rule 17.5, may obtain all supporting information relied upon by an Applicant in developing any ground water modeling, or alternative methodologies. The Applicant's obligation to disclose such information arises upon request of any party and, to the extent that the Applicant deems and the State Engineer finds any such information sensitive, confidential, or proprietary, the parties and State Engineer shall agree to hold such information confidential and protect it from public dissemination under appropriate terms and conditions. E. Professional Report 1. The supporting data for a petition shall be assembled in a professional report and shall include appendices of the data and calculations used to demonstrate that the ground water is not connected to the surface water system or that the ground water otherwise meets the statutory definition of nontributary ground water as set forth at section 37-90-103(10.5), C.R.S. 2. A detailed map of the proposed nontributary area shall accompany the report and shall be overlain on a standard U.S.G.S. topographic map with scale 1:24000 inches when such area can be shown within the boundary of 7 mile by 14 mile map area. For larger areas, a topographic base map with a scale of 1:50000, 1:100000 or 1:250000 inches may be utilized; using the largest scale possible that will enclose the entire area of the nontributary ground water determination, wells, and locations of data points, surveys, and other features related to the petition. 3. Standard Data Format — For consistency in reporting, the following parameters shall be used as the standard format and units for reporting the stated types of data: Where: L = length (feet); f = time (day). a. Hydraulic conductivity (K) shall be reported in units of L/t (ft/day). b. Transmissivity [T] shall be reported in units of L2/t (ft2/day). c. Water production rate [Q] shall be reported in units of L3/t (ft3lday). d. Specific storage (S5) shall be reported in units of L-1(1/ft). e. Water volume shall be reported in units of L3(ft3). f. Specific yield, storativity or storage coefficient shall be reported as a ratio. g. Thicknesses (aquifer, formation, etc.) shall be reported in units of L (feet). h. Distances shall be reported in units of L (feet). 4. The Applicant shall submit two paper copies of the report and appendices and one electronic copy, including GIS shape files, in a format deemed acceptable by the State Engineer's Office. Produced Nontributary Ground Water Rules 2 CCR 402-17 8 5. A petition for multiple production zones may be submitted with a single report utilizing data from a source or sources that include the same geographic/geologic area. 17.7 Specific Locations of Nontributary Ground Water in Colorado Ground water in the State of Colorado is legally presumed to be "tributary," or hydraulically connected to surface water in such a fashion so as to require administration within the prior appropriation system in conjunction with surface rights, unless it is demonstrated to be nontributary ground water in accordance with the law. See Simpson v. Bijou Irrigation Co., 69 P.3d 50, 57 n.7 (Colo. 2003). For purposes of administration under section 37-90-137(7), C.R.S. absent a determination made pursuant to Rule 17.5 of these Rules, or other Rulemaking, the State Engineer shall regard all Produced Water within the State of Colorado to be tributary, with the exception of the ground water described in Rule 17.7.A through D. A. The Denver Basin The State Engineer shall regard the bedrock aquifers of the Denver Basin (the Dawson, Denver, Arapahoe, and Laramie -Fox Hills) to be nontributary only where shown to be nontributary by the Denver Basin Rules, 2 CCR 402-6. Pursuant to section 37-90- 103(10.7), C.R.S., the State Engineer shall regard al! remaining ground water in the bedrock aquifers of the Denver Basin subject to the Denver Basin Rules to be not nontributary. B. Water Rights Found to be Nontributary by a Valid Court Decree The State Engineer shall regard all water rights that are decreed nontributary by a court to be nontributary only to the extent provided by the court decree and only insofar as such water is used in a manner wholly consistent with the terms and conditions of such decree. C. Existing Ground Water Well Permits House Bill 09-1303, Section 3, codified at section 37-90-137(7)(c), C.R.S. provides "[a]ny rules promulgated pursuant to this subsection (7) shall not conflict with existing laws and shall not affect the validity of ground water well permits existing prior to the adoption of such rules." Therefore, the State Engineer shall regard as nontributary all ground water permitted for withdrawal as nontributary ground water pursuant to well permits issued by the State Engineer prior to the adoption of these Rules. D. For the purpose of meeting the objectives in the scope and purpose of these Rules, Rule 17.7.D. identifies geographically delineated areas under which the ground water in only certain formations is nontributary for the limited purposes of these Rules. Small-scale maps showing the extents of the delineated areas and identifying the geologic formations are included as a reference in an appendix to these Rules. Larger -scale maps are available on the Division of Water Resources' website along with an electronic version of these Rules. The small-scale and large-scale maps show identical areas and each are incorporated as part of the Rules. The delineated areas may be viewed through Division of Water Resources' public data viewing tools as they are developed Produced Nontributary Ground Water Rules 2 CCR 402-17 9 and the data files describing the areas are also available for downloading from the Division of Water Resources' website. 1.

This engine is equipped with no controls. This emission unit is used to power electric pumps, for heat tracing and facility lighting. This engine will be located at the Pond 10 Generator, in the SESW Section 5, Township 7S, Range 97W, in Garfield county, Colorado. It has been determined that this engine is exempt from permit requirements. The filing of an Air Pollutant Emissions Notice(s) (APEN) is required. The above emission unit is a listed source that Is specifically exempt from construction permit requirements, per Regulation No. 3, Part B, Section II.D.1.c.iii. Specifically, this exemption has been granted because emissions of nitrogen oxides and carbon monoxide are less than 10 tons per year each and the source is located in an attainment area. If this engine is replaced with another engine, with uncontrolled actual emissions Tess than 10 tpy or manufacturer's site -rated horsepower less than 100, this exemption shall remain valid as long as a revised APEN is filed with the Division reflecting the change in equipment. This source shall be limited to a maximum consumption rate as listed below and all other activities, operational rates and numbers of equipment as stated in the application: Consumption of natural gas as fuel shall not exceed 30.61 MMscf per year. This exemption from permit requirements is issued in reliance upon the accuracy and completeness of information supplied by the applicant and Is conditioned upon construction, installation and operation in accordance with this information and with representations made by the applicant or applicant's agents. AIRS: 045121291003 Page 1 of 2 NGEnglne XP Version 2009-1 According to the Division's preliminary analysis, based on the submitted data and information, the equipment dentified above will result in the emission of the following air pollutants. Annual fees will be billed for this source in accordance with and in the amounts and limits specified in the provisions of Colorado Revised Statutes section 25-7-114.1. Facility Equipment ID AIRS Point Tons per Year NOx CO VOC G01 003 8.15 7.21 2.61 It should be noted that although exempted sources may not need air emission permits, they are still required to meet all applicable standards and regulations of the Air Quality Control Commission, including visible emissions shall not exceed 20% opacity. A Revised Air Pollutant Emission Notice (APEN) shall be filed: (Reference: Regulation No. 3, Part A, Section II.C.) a. Annually whenever a significant increase in emissions occurs as follows: For any criteria pollutant: For sources emitting less than 100 tons per year, a change in actual emissions of five tons per year or more, above the level reported on the last APEN submitted; or For any non -criteria reportable pollutant: If the emissions increase by 50% or five (5) tons per year, whichever is less, above the level reported on the last APEN submitted to the Division. b. Whenever there is a change in the owner or operator of any facility, process, or activity; or c. Whenever new control equipment is installed, or whenever a different type of control equipment replaces an existing type of control equipment; or d. Whenever a permit limitation must be modified; or e. No later than 30 days before the existing APEN expires. The APEN associated with this exemption shall expire on 612012016. Any changes with respect to the original submittal which would result in increases in either emissions or ambient air impacts, or which would result in the emission of any pollutants not listed in the original submittal, automatically nullifies this exemption. Before actually making any such change, you must apply to the Division for a new exemption based on the anticipated change; if the Division denies the new exemption, you will have to obtain a permit before implementing the change.

This equipment, although currently installed at the facility, is not in operation. The intent of this assessment was to review the equipment specifications provided by the manufacturer (Attachment A), and determine if the equipment's operation would be in compliance with the noise limits set forth in the Colorado Oil and Gas Conservation Commission (COGCC) Rule 802 and Section 25-12- 103 of the Colorado Revised Statutes (CRS). The COGCC and CRS limits are the same for general noise measurements. Figure 1 shows the facility location, noise generating equipment location and distance to compliance point(s). Noise Generating Equipment The noise generating equipment is one generator enclosed in a fabricated enclosure. Compliance Point(s) The COGCC Rule 802 uses the property line or 350 feet from the noise generating equipment, whichever is greater, as the compliance point for oil and gas operations. The nearest property boundary is 570 feet south of the noise generating equipment. Therefore Olsson has used 570 feet away from the noise generating equipment as the compliance point. Olsson has also calculated the sound pressure levels at 2,100 feet from the noise generating equipment to ensure that noise would not be a nuisance at the nearest occupied structure(s), located over 2,100 feet to the south. Maximum Permissible Noise Levels As prescribed in COGCC Rule 802, in remote locations, where there is no reasonably proximate occupied structure or designated outside activity area, the light industrial standard may be applicable. The night time maximum permissible noise limit is 65 db(A) for light industrial areas. 760 Horizon Drive, Suite 102 TEL 970.263,7800 Grand Junction, CO 81506 FAX 970.263.7456 www.olssonassociates.com 013-0656 Noise Analysis - Oxy Pond 10 Generator Building 03/31/14 The night time maximum permissible noise limit is 50 dB(A) for residential areas. This noise pressure limit has been used to ensure that the noise generating equipment would not be a nuisance at the nearest occupied structure(s). Calculated Sound Pressure Levels The generator/enclosure is rated to a sound pressure level of 81.78 dB(A) at 15 meters (42.9 feet) by the manufacturer (see Attachment A). This sound pressure level includes sound generated from engine mechanics and exhaust and also accounts for building attenuation. Olsson has assessed the potential noise level at 570 feet using the noise/distance extrapolation equation provided in COGCC Rule 802 and the generator/enclosure rating. The calculated sound pressure level at 570 feet from the equipment will be approximately 60.5 dB(A) (see Attachment B). Olsson has also assessed the potential noise level at 2,100 feet using the noise/distance extrapolation equation and the enclosure. The calculated sound pressure level at 2,100 feet from the equipment will be approximately 49.2 dB(A) (see Attachment B). Conclusion The noise pressure calculation shows that the levels should be below the light industrial limit at 570 feet from the equipment and below the residential limit at the nearest occupied structure. These sound pressure levels are calculated and actual noise levels should be measured during equipment operation to insure regulatory compliance. Statement of Qualification I am a multi -disciplinary Project Manager at Olsson Associates. I have coordinated many Noise Control Regulation Compliance Assessments over 5 years at existing and planned noise generating equipment installations in Colorado.

Note that deration occurs as the methane number decreases. Methane number is a scare to measure detonation characteristics of various fuels. The methane number of a fuel is determined by using the Caterpillar Methane Number Calculation program. ALTITUDE DERATION FACTORS: This table shows the deration required for various air inlet temperatures and altitudes. Use this information along with the fuel usage guide chart to help determine actual engine power for your site. ACTUAL ENGINE RATING: Itis important to note that the Altitude/Temperature deration and the Fuel Usage Guide deration are not cumulative. They are not to be added together_ The same is true for the Low Energy Fuel deration (reference the Caterpillar Methane Number Program) and the Fuel Usage Guide deretion. However, the Altitude/Temperature deration and Low Energy Fuel deration are cumulative, and they must be added together in the method shown below_ To determine the actual power available, take the lowest rating behveen 1 j and 2). 1) (Altitude/Temperature Deration) + (Low Energy Fuel Derafion) 2) Fuel Usage Guide Deraticn Note: For NA's always add the Low Energy Fuel deration to the Altitude/Temperature deration. For TA engines only add the Low Energy Fuel deration to the Altitude/Temperature deretion whenever the Alfiiudelremperature deration is less than 1.0 (100%). This will give the actual rating for the engine at the conditions specified. AFTERCOOLER HEAT REJECTION FACTORS IACNRF): Anercooler heat rejection is given for standard conditions of 77°F and 500 ft altitude. To maintain a constant air inlet manifold temperature, as the air to turbo temperature goes up, so must the heat rejection. As altitude increases, the turbocharger must work harder to overcame tho lower atmospheric pressure. This increases tha amount of heat that must be removed from the inlet air by the altercooler. Use the altercooler heat rejection factor (ACHRF) to adjust for ambient and altitude conditions, Multiply this factor by the standard anerccoler heat rejection. Failure to properly account for these factors could result in detonation and cause the engine to shutdown or fail. SOUND DATA; Data determined by methods similar to ISO Standard DIS-852E-10.

The site will be used to store oilfield equipment including pipe, fittings, valves, and tanks. No occupied structures are planned to be constructed onsite. The site lies at an elevation greater than 5,800 feet above mean sea level (amsl). The Location Map shows the general location of the Pond 10. The purpose of this report is to identify geologic conditions that may pose hazards to a land development project in order that appropriate mitigation or avoidance techniques may be implemented as described in the Garfield County LUDC. According to the Garfield County LUDC, Section 7-207, the types of natural and geologic hazards identified pertain to the following: A. Utilities; B. Development in Avalanche Hazard Areas; C. Development in Landslide Hazard Areas; D. Development in Rock Fall Hazard Areas; E. Development in Alluvial Fan Hazard Areas; F. Slope Development; G. Development on Corrosive or Expansive Soils and Rock; H. Development in Mudflow Areas; and I. Development Over Faults. This report presents Olsson findings following an evaluation of these and other geologic hazards potentially affecting the site and proposed development. The site was found to be suitable for the proposed development, but is in an area of steep slopes within Conn Creek canyon. Although the area has not been mapped for geologic hazards, there is a potential for unstable or potentially unstable slopes and associated rock fall and slides to impact the development. Steep slopes are found in areas to the northeast and east of the Pond 10 Site. There is an intermittent drainage on the north side of the Pond 10 Site that drains to Conn Creek. Rockfall and slide mitigation should be designed by a qualified and licensed professional engineer in accordance with Section 4-203 and Section 7-108 of the LUDC. A qualified licensed professional engineer should make the final determination on how to best mitigate these risks. A diversion ditch has been constructed around the perimeter of the produced water pond. A stormwater retention pond is proposed on the southeast corner of the site. A low hill located on the east side of the site is proposed to be graded with a 2:1 slope. This hill separates the Pond 10 Site from the drainage swale and the steep slopes to the east and northeast of the Site. This report should be read in its entirety, including but not limited to the conclusions and recommendations in section 4.0. Geologic Hazard Report OXY Pond 10 Garfield County, CO Project #013-0656 1 Olsson Associates Golden, Colorado March 2014 2.0 GENERAL SITE LOCATION AND BACKGROUND Oxy contracted Olsson Associates (Olsson) to conduct a natural and geologic hazards assessment as part of the proposed development of the Pond 10 Site. The following sections provide information about the proposed development and the site geologic setting. The Topographic Map shows the location of the Pond 10 Site. 2.1 Project and Site Description The Oxy Pond 10 Site will be used as a centralized exploration and production (E&P) waste management facility per the Colorado Oil and Gas Conservation Commission (COGCC) Rule 908. The site consists of adjacent ponds that are being permitted as one facility for the storage of produced water. The Pond 10 Site is located near Conn Creek north of the town of DeBeque in western Garfield County, Colorado. The site is located in the southeast quarter of the southwest quarter of Section 5, Township 7 South, Range 97 West, of the 6th Principal Meridian. 2.2 Structural Geology The proposed Pond 10 Site is located in the south-eastern part of the Piceance Basin; an irregularly-shaped elongated basin formed by tectonic forces associated with the Laramide orogeny. Tectonic forces downwarped the earth's crust to form the Piceance Basin as a result of the uplift of the surrounding Colorado Rocky Mountains and the Colorado Plateau. The site is located on the Roan Plateau in the proximity of Red Pinnacle. The site is located on the Red Pinnacle 7.5 -minute topographic map. The Piceance Basin is the major structural geologic feature in the region. It is bound to the east by the Grand Hogback monocline, the White River Uplift to the northeast, the Gunnison Uplift to the south, the Uncompahgre Uplift to the southwest, the Douglas Creek Arch to the west- northwest, and the axial basin uplift to the north (Grout and Verbeek, 1992). The central Roan Plateau area covers an area of approximately 230 square miles in Garfield and Rio Blanco Counties in the south-central part of the Piceance Basin in northwestern Colorado. Sedimentary rocks in the southwestern Piceance Basin gently dip to the north - northeast except where this regional dip is interrupted by low -amplitude folds. Numerous small sub - parallel northwest trending folds have been identified in the Green River Formation within the basin. The project site is located approximately 3 miles to the south of the Crystal Creek anticline. The Pond 10 storage Site is located near the axis of the Clear Creek syncline which passes through the southwest quarter of Section 5. The Crystal Creek anticline and the Clear Creek syncline are a northwest trending fold system that start near the Colorado River and extend for a distance of approximately 30 miles. The Crystal Creek anticline forms the southeastern element of an anticlinal fold that trends across the southwestern part of the Piceance Basin. The Clear Creek syncline is a parallel fold located to the southwest (Hail, 1992). Geologic Hazard Report OXY Pond 10 Garfield County, CO Project #013-0656 2 Olsson Associates Golden, Colorado March 2014 A fault is a fracture in rock along which movement has occurred. No significant faulting is known in the project area, but some jointing may occur in proximity to the folds. Three narrow down -dropped block valleys, known as grabens, and bound by normal faults are present along a northwest trending fracture zone in the northern part of the area. The maximum stratigraphic displacement on these faults does not exceed 120 feet and most displacements are considerably less. Small northwest striking faults between the graben in the central part of Township 4 South, Range 97 West and the graben in southwestern part of Township 4 South, Range 96 West suggest that the grabens lie along a single fracture zone that extends for a total distance of approximately nine miles (Hail, 1992). 2.3 Site Bedrock Geology As shown on the attached Geology Map, the bedrock underlying the proposed Site is composed of the lower part of the Green River Formation. These units are composed of claystone, siltstone, shale, and marlstone. The Roan Cliffs expose hundreds of feet of the Green River Formation. The Green River Formation has been subdivided into four members which include the basal Douglas Creek member, Garden Gulch member, the Anvil Points member, and the Parachute Creek Member. Underlying the Green River Formation are the early Eocene and Paleocene Wasatch and Fort Union Formations as well as the Cretaceous Mesaverde Group (Robson and Banta, 1995). The lower part of the Green River Formation is comprised of the Douglas Creek and Garden Gulch members and is considered a confining unit that separates the overlying Lower Piceance Basin aquifer in the Anvil Points Member from the underlying Fort Union and Mesaverde aquifer. A thin layer of modern alluvium associated with the Conn Creek drainage covers the bedrock near the site. 2.4 Site Surficial Geology and Soil The proposed Pond 10 Site is located on Pleistocene and Holocene deposits that include alluvium, alluvial fans, talus, and slope wash. These surficial deposits consisting of silt, sand, and clay were derived primarily from the weathering of the Green River Formation and . Erosional processes dominate in this setting, as the weathered soils are drawn toward the surrounding canyons by precipitation, snowmelt, and wind. The Soils Map shows the soil types beneath the site and surrounding properties. The proposed Site is underlain by soils mapped by the U.S. Natural Resources Conservation Service as the Happle very channery sandy loam, which is a deep, well -drained soil found on alluvial fans occupying 3 percent to 12 percent slopes, at elevations of 5,200 to 6,000 feet, It is formed in alluvium derived dominantly from the Tertiary Green River Formation. The surface layer is typically light gray very channery sandy loam in the upper 7 inches and grades into a very pale brown. Permeability is moderate, and the available water capacity is low in the Happle soil. The effective rooting depth is 60 inches or more. Runoff is slow, and the hazard of water erosion is severe. Geologic Hazard Report OXY Pond 10 Garfield County, CO Project #013-0656 3 Olsson Associates Golden, Colorado March 2014 The Happle very channery sandy loam has a pH range of 7.4 to 8.4 standard units. According to the Soil Survey of the Douglas -Plateau Area, Colorado these soils are somewhat limited for local roads and streets due to frost action, are somewhat limited for shallow excavations due to cutbank caves. Small commercial buildings are limited due to slope; however, small dwellings with or without basements are not limited. 2.5 Hydrologic Setting Surface water features within two miles of the project site include Conn Creek, approximately 450 feet to the west. The confluence of Conn Creek and Gilman Gulch is located approximately one mile to the northwest, and the confluence of Conn Creek with East Fork Canyon is located approximately one mile south. The proposed Pond 10 Site will be located adjacent to an existing facility, Coyote Pond/10 South, COGCC facility ID #291946. There is a chute with an intermittent drainage located to the north of the facility. The site is shown on the USGS 1:24,000 topographic map (Red Pinnacle Quadrangle). Conn Creek has perennial flow, although no flow records are available to determine the flow conditions in these drainages. Evaluation of aerial imagery in Google Earth taken in August 2011 shows very little to no flow in Conn Creek near the proposed storage facility. A stock pond is located approximately 330 feet to the southwest of the site. The Surface Water Map shows the site in proximity to Conn Creek and the stock pond. 2.6 Aquifers The Pond 10 Site is located on a low alluvial terrace above Conn Creek. Shallow groundwater is contained within the modern alluvium and is directly in communication with surface water in Conn Creek. The Uinta — Animas aquifer in the Piceance Basin consisting of the Uinta Formation and the Parachute Creek Member of the Green River Formation lie topographically and stratigraphically above the Site and therefore would not be affected by the site. The bedrock in the area of the Pond 10 Site consists of the lower part of the Green River Formation and the Wasatch Formation which form a confining unit Groundwater is expected to lie at depths more than 40 feet below ground surface based on area water well records from the Colorado Division of Water Resources for nearby wells. This groundwater is contained within alluvium and terrace deposits and is in communication with the flow in Conn Creek. A spring is shown on the Red Pinnacle topographic map in the northern part of Section 5. Geologic Hazard Report OXY Pond 10 Garfield County, CO Project #013-0656 4 Olsson Associates Golden, Colorado March 2014 3.0 NATURAL AND GEOLOGIC HAZARD ASSESSMENT The following sections present the assessment of geologic hazards in the vicinity of the proposed Pond 10 Site. This site was previously developed for use as a produced water storage facility. 3.1 Utilities Installation of buried utilities may be affected by the relatively shallow depth to sedimentary bedrock and fractures within the bedrock substrate. The Pond 10 Site is to be used for the storage of produced water as a Centralized E&P Waste Management Site and has been engineered and designed to have a double -liner system. An access road that is approximately 750 feet will be constructed around the perimeter of the produced water storage facility. 3.2 Avalanche Hazard Area The site is not located in a known avalanche hazard area. Winters are cold in the mountainous areas of Garfield County and valleys are colder than the lower pars of adjacent mountains due to cold air drainage. Average seasonal snowfall in Garfield County is 50 inches. The greatest snow depth at any one time during the period of record from 1951 to 1974 was 29 inches recorded at Rifle, Colorado. The Pond 10 Site and the access road are not expected to be within an avalanche prone area. Therefore, avalanches are not expected to pose a hazard to the proposed development. 3.3 Landslide Areas or Potential Landslide Hazard Areas The site and access road are not located within an area that has been mapped with landslide hazard areas. It is on an alluvial terrace in an area surrounded by steep slopes composed of the Green River Formation. It appears that there are slide areas located to the north and south of the Pond 10 Site based on site photographs and aerial photography. Debris fans appear at the base of the slopes and appear to have mature vegetation covering them. It is possible for future slides and rock fall to occur in this area. 3.4 Rockfall Areas The Site and access road are in an area of rockfall or potential for rockfall. Rockfall areas are present to the northeast and east-southeast in the steep precipices as shown on the adjacent land use map and the parcel location map. The site is located in between two chutes where rocks have slid down the steep sides of the canyon in the past, and therefore have the potential for future rockfalls. Geologic Hazard Report Oxy Pond 10 Facility Garfield County, CO OA Project #013-0656 5 Olsson Associates Golden, Colorado March 2014 The Site will be constructed with a buffer area around the perimeter to protect it in the event of rock falls. According to draft working copy plans prepared by DR Griffin & Associates, of Rock Springs, Wyoming, dated 03/06/2014 the pond will be located approximately 25 feet from the toe of the slope and a low hill to the east of the Site will have a maximum height of 5 feet to 10 feet above the base of the swale, and 35 feet above the base of the Pond 10 pad. The swale will vary in width from 12 feet to 2 feet, and in depth from one foot to five feet. The access road coming into the south side of the Site is at the toe of a historic rock slide. A qualified licensed professional engineer in accordance with Section 4-203 and 7-108 of the LUDC should make the final determination on how to best mitigate rockfall risks. 3.5 Alluvial Fan Hazard Areas The Site is not located in a mapped alluvial fan hazard area. Alluvial fans are present at the mouths of the canyons where they discharge onto the Colorado River floodplain. 3.6 Unstable or Potentially Unstable Slopes Slopes to the north and east are potentially unstable. The pond has an access road and water diversion around the uphill side and the sides of the pond are built up with gabions. These engineering controls are expected to mitigate rockfall, slides, or debris flows. Development of areas with moderate slope hazard consisting of debris fans and minor rockfall areas should include a detailed geologic investigation to accompany an engineering study including test drilling, simple strength tests, groundwater evaluation and stability analysis. Mitigation is usually possible, but could be expensive and may involve large scale construction work. Much of the area immediately north and west of the towns of DeBeque and Parachute is considered to have major slope hazards. An area of major hazard, such as active landslide area, may include more investigation which includes geologic study, intensive drilling, and sophisticated strength testing stability analyses, and monitoring of soil, rock, and groundwater conditions during the engineering and design phase of the project. Mitigation may be possible, but also may be expensive, may require special siting, and will involve some risk. Avoidance may be recommended for projects of lower economic value (Garfield County, Slope Hazard Study 2002). 3.7 Corrosive or Expansive Soils and Rock The Pond 10 Site and access road are not located in an area known to have expansive soil or rock types, although building site development for local roads and streets is somewhat limited due to frost action, and shallow excavations are somewhat limited due to cutbank caving. Sedimentary rock containing high salt content, such as bicarbonate, chloride or sulfate, and soils derived from these rock types, may be corrosive to concrete or metal, causing damage to Geologic Hazard Report Oxy Pond 10 Facility Garfield County, CO OA Project #013-0656 6 Olsson Associates Golden, Colorado March 2014 structures built upon them. The potential for the Happle soils have a high potential of corrosion to uncoated steel, but a low potential of corrosion to concrete. This is not expected to be an issue with the proposed development since the project involves construction of a produced water pond. This site was previously developed for use as a produced water storage facility. Some Tertiary and Cretaceous age sedimentary rocks with high clay content are capable of accepting water into their chemical structure and expand many times their volume when dry. These sedimentary rocks, and soils formed from these rock types, may expand or contract as they become wet and then dry out resulting in damage to structures built upon them. Expansive soil conditions are not expected to constitute a hazard at this Site. 3.8 Mudflow and Debris Fan Areas The Pond 10 Site is not located in an area mapped as having mudflows or debris fans. However, it appears that there is a drainage on the north side of the Pond 10 Site and there does appear to have small debris fans supporting vegetation to the northeast of the Site. There is also a slide area and debris fan to the east-southeast of the Site. The toe of the slide is close to the location of the proposed stormwater retention pond. There is a slope and escarpment adjacent to the Site and they have built a berm to channel water away from the pads. Engineering controls may be needed to divert debris fans away from the Site. 3.9 Development Over Faults No significant faulting is known in the project area, but some jointing may occur in proximity to the folds mentioned in the structural geology section. Three narrow down -dropped block valleys, known as grabens, and bound by normal faults are present along a northwest trending fracture zone several miles north of the Pond 10 Site. The maximum stratigraphic displacement on these faults does not exceed 120 feet and most displacements are considerably less. Small northwest striking faults between the graben in the central part of Township 4 South, Range 97 West and the graben in southwestern part of Township 4 South, Range 96 West suggest that the grabens lie along a single fracture zone that extends for a total distance of approximately nine miles (Hail, 1992). According to the Geologic Map of the Red Pinnacle Quadrangle Map (Donnell et al, 1992) does not show any faults in proximity to Pond 10 Site. There are no mapped faults in the immediate vicinity of the proposed site. Colorado is considered a region of minor earthquake activity; however, there is uncertainty due to the relatively short historic record. According to the USGS Colorado Earthquake History online, newspaper accounts were the primary source of earthquake data in Colorado prior to 1962. Few earthquakes have been reported in this part of Colorado. The Roan Plateau is not in an area of known seismic activity; and therefore, earthquakes are not expected to present a significant hazard. Geologic Hazard Report Oxy Pond 10 Facility Garfield County, CO OA Project #013-0656 7 Olsson Associates Golden, Colorado March 2014 3.10 Flood Prone Areas According to available information from the Federal Emergency Management Agency (FEMA) National Flood Insurance Program, Flood insurance Rate Map (FIRM), the site is not located within the 100 -year floodplain or 500 -year floodplain. The Floodplain Map was prepared for the vicinity of the town of De Beque and along the Colorado River. It is not in close proximity to the Pond 10 Site. Flash floods could pose a hazard for the small intermittent drainage located to the north of the Site. The engineering and design of the Pond 10 Site include a drainage plan to address this issue and divert storm water away from the ponds. 3.11 Collapsible Soils Collapsible soil conditions may be present in alluvial fan, alluvial, colluvial, and eolian depositional environments, and are found in some areas along the Colorado River drainage where fine-grained sediments have been deposited from higher elevations, but are not expected to be present in the vicinity of the Pond 10 Site. Collapsible soils are another type of subsidence that occurs in parts of Colorado where unconsolidated sediments are present. This ground settlement can damage man-made structures such as foundations, pavements, concrete slabs, utilities, and irrigation works. Hydrocompactive soils are the most common type of collapsible soils. The presence or introduction of water causes the soils to compact once they become wet. Hydrocompactive soils form in semi -arid to arid climates in the western United States and large parts of Colorado in specific depositional environments. Collapsible soils have a low density and low moisture content where the grains are not packed tightly together. These soils are strong in dry conditions, where the loose skeletal fabric of these soils is preserved because the grains are "tack -welded" due to the presence of binding agents, such as clay or silt, soil suction pressures, or other binding agents that can break, soften, disperse, or dissolve when wet causing subsidence or settling. Silty clay and clayey sandy soils onsite are potentially collapsible, although less likely onsite than subsidence due to expansive soils. 3.12 Mining Activity A review of the Red Pinnacle 7.5 -minute topographic map shows several drill holes for exploration of oil shale, but does not show underground mining of oil shale in the vicinity of the Pond 10 Site. Subsidence is not expected to be a geologic hazard affecting the Pond 10 Site. 3.13 Radioactivity According to Colorado Geologic Survey Bulletin 40, Radioactive Mineral Occurrences of Colorado, the only naturally occurring radioactive mineral occurrences in Garfield County Geologic Hazard Report Oxy Pond 10 Facility Garfield County, CO OA Project #013-0656 8 Olsson Associates Golden, Colorado March 2014 include uranium and vanadium deposits that occur near the town of Rifle (Nelson -Moore, Collins, Hornbaker, 2005). These deposits are located in older Jurassic age sediments, are not exposed in the vicinity of the site, and lie stratigraphically below the zones that are developed for oil and gas production. Therefore, radioactivity is not expected to pose a hazard. The Colorado Department of Public Health and Environment (CDPHE) has posted a statewide radon potential map on their website based on data collected by the EPA and the U.S. Geological Survey. Garfield County and most of Colorado has been mapped as being within Zone 1 — High Radon Potential, or having a high probability that indoor radon concentrations will exceed the EPA action level of 4 picocuries per liter (pCi/L). Radon is not expected to be a hazard at the Pond 10 Site since the site will generally not be occupied for extended periods and will not have occupied structures containing basements or substructures in which radon can accumulate. Colorado oil and gas operations are not known to have a significant problem with naturally occurring radioactive materials (NORM) or technologically enhanced naturally occurring radioactive materials (TENORM); however, there have been some instances where pipe scale has contained radium and associated radon gas. Geologic Hazard Report Oxy Pond 10 Facility Garfield County, CO OA Project #013-0656 9 Olsson Associates Golden, Colorado March 2014 4.0 Conclusions and Recommendations The following conclusions and recommendations were made following a review of the available site data for natural and geologic hazards in the vicinity of the Oxy Pond 10 storage Site located in Garfield County, Colorado. • Geologic hazards were identified in the immediate vicinity of the Oxy Pond 10 Site. These include steep slopes and potential landslides, debris flow, and rock fall. • Avalanche areas are present in the northeastern parts of Garfield County in parts of the Park Range and Flat Tops mountain range. Avalanche conditions are not expected to be a hazard in area of the Pond 10 Site. • Landslide areas have not been mapped in the vicinity of the Pond 10 Site. However, there is evidence of slides or debris flows located to the northeast and east-southeast of the Pond 10 Site. • Rockfall areas are present to the south along steep cliff faces of the Conn Creek Canyon and Gilman Gulch. Rockfall mitigation should be designed by a qualified licensed professional engineer in accordance with Section 4-203 and 7-108 of the LUDC. • Alluvial fan hazard areas are not present in the vicinity of the Pond 10 Site, but are present further to the south in some areas along the Colorado River drainage. • Slope development is not expected to be an issue on the Pond 10 Site, but there are steep slopes to the northeast and east of the Site. Engineering controls may be needed to control rock fall and slides. • Corrosive or expansive soils and rock are not present in the vicinity of the Pond 10 Site. • Collapsible soils are not present in the vicinity of Pond 10 Site. • No significant faulting is known in the Pond 10 Site. • No flood prone areas are mapped in the vicinity of the Pond 10 Site. Flash flooding is an issue for lower elevations along Conn Creek, and areas along the Colorado River are prone to flood risks. • There are no mining activities shown in the vicinity of the site. • There are no naturally occurring radioactive mineral deposits known in the site area. NORMITENORM may be an issue with exploration and production. The Pond 10 Site is not expected to have any occupied structures constructed on it, and the Site will be used for the storage of produced water. Slopes to the north and east are potentially unstable. An access road and diversion ditch have been constructed around the perimeter of the produced water pond. There is a setback of approximately 25 feet to 30 feet from the slopes to the east and northeast. These engineering controls are expected to mitigate potential rockfall, slides, or debris flows from steep slopes to the northeast and east. Appropriate risk mitigation design should be determined by a qualified, licensed professional engineer should be performed as a part of this upgrade development. Geologic Hazard Report Oxy Pond 10 Facility Garfield County, CO OA Project #013-0656 10 Olsson Associates Golden, Colorado March 2014 5.0 Natural and Geologic Hazard Report Background Garfield County Colorado finalized the Land Use and Development Code (LUDC) with an effective date of July 15, 2013. According to Section 7-108 Use of Land Subject to Natural Hazards of the Garfield County LUDC "Land subject to identified Natural and Geologic Hazards, such as falling rock, landslides, snow slides, mud flows, radiation, flooding, or high water tables, shall not be developed unless it has been designed to eliminate or mitigate the potential effects of hazardous site conditions as designed by a qualified professional engineer and as approved by the County." The LUDC requires a Natural and Geologic Hazard Study be prepared by a qualified professional geologist be submitted with a development plan or plat. The LUDC defines a geologic hazard as "A geologic phenomenon that is so adverse to past, current, or foreseeable construction or land use as to constitute a significant hazard to public health and safety or to property." The LUDC defines a Hazard Area as "An area that contains or is directly affected by a geologic hazard, including but not limited to the following types of areas." A. Avalanche Area. "A mass of snow or ice and other material that may become incorporated therein as such mass moves rapidly down a Slope." B. Landslide Area. "An area with demonstrably active mass movement of rock and soil where there is a distinct surface rupture or zone of weakness that separates the landslide material from more stable underlying material." C. Mudflow Debris Area. "An area subject to rapid mud and debris movement or deposit occurring after mobilization by heavy rainfall or snowmelt runoff. Such areas are formed by successive episodes of deposition of mud and debris." D. Radioactive Area. "An area subject to various types of radiation emission from radioactive minerals that occur in natural or manmade deposits of rock, soil, or water." E. Potentially Unstable Soils. "An area of land identified as having soils that may cause damage to structures, such as buildings and roadways, as a result of over saturation or some other outside influence."

Geology reports shall be prepared by either a member of the American Institute of Professional Geologists, a member of the Association of Engineering Geologists, or a qualified geotechnical engineer licensed in the State of Colorado." Geologic Hazard Report Oxy Pond 10 Facility Garfield County, CO OA Project #013-0656 11 Olsson Associates Golden, Colorado March 2014 A search of the Colorado Department of Regulatory Agencies (DORA), Licensed Professionals and Businesses indicates that Colorado licenses "professional engineers" and "engineer interns" but does not appear to have a license specific to "geotechnical engineers." Currently the state of Colorado does not require licensure or registration of geologists. Colorado Revised Statutes do require that geologic reports be prepared or authorized by a professional geologist. "Professional Geologist" is a term defined in Colorado Statutes.

Pond 10 Upgrade: Landslide and Rockslide Assessment 19 March 2014 POND 10 UPGRADE PROJECT LANDSLIDE AND ROCKSLIDE ASSESSMENT ASSESSMENT OVERVIEW There is minimal risk to personnel or infrastructure from rocksiides or landslides. The configuration of the facility, the frequency of personnel exposure, and a lack of oil and gas infrastructure mitigate potential risk. This facility is an impoundment for storing approximately 90,000 bbl of produced water. The water enters the impoundment through belowground pipelines or water trucks. There is no storage or processing equipment for oil or natural gas on the site. There is a buffer zone to the east which consists of a berm and swale, that in conjunction with distance, will arrest rolling or falling debris. Examination of the site reveals no evidence of large rocks or debris having made it past this buffer to impact the facility. Personnel risk is further reduced by the fact that the facility is not continuously manned. EXISTING CONFIGURATION The imagery above shows the four reference points from which the following photographs were taken. The satellite photo is oriented with north towards the top of the page. The photographs show that the berm and swale serve as an obstacle to debris and that there is no evidence of significant rockslide or landslide activity. 2 QXY Pond 10 Upgrade.

From Reference 4 Facing North FUTURE CONFIGURATION The following drawing is from the design of the future facility. It shows that the existing buffer zone will be maintained so that there is no increased risk. The north -south running swale and berm will be reconfigured, but will retain their character as a trap and barrier to arrest possible debris. The drawing is oriented with north towards the top of the page. 6 Pond 10 Upgrade: Landslide and Rocksilde Assessment 19 March 2014 • ‘11 ♦\\1 1114 • • 1\1 -- I 1\\ ,`,:, \1\ ♦♦♦ `♦ ▪ • ♦\ 1\ �`1� 5ti I�i� 111 1 1 1 1 - \ \\ •1 ( ``�., 1\ \\ \ 11 1 wet i e -V,-.5' 1�,1i - \1 11 1• N. ,87.E ♦IAEA 2 ♦ \` ., ♦♦ \\ ▪ \ ▪ ~`�♦- \1 1 •1. ` 11f1 4' 1 ;'\ 1 w s. . �. .+int.., ♦♦` ♦��,,��` 11 �1 \ �` li:�y. �;��.
