The proposed site will be located on private property, owned by OXY USA WTP LP, approximately 12 miles north of DeBeque, Colorado. The site will be defined as a Water Impoundment with storage as an accessory use. TheAfacility’sAmainA function will be to store produced water in a location centralized to OXY’sAproduction field. 1.1 Description The purpose of the proposed Pond 10 site is to increase efficiency in the transportation and use of produced water within the OXY Cascade Creek field. The proposed water impoundment site will reduce overall heavy traffic on county roads by allowing vehicles to transport produce water to a pond within OXYs property. The parcel is currently owned by OXY USA WTP LP. Pond 10 will eliminate the need to transport fresh water for natural gas extraction and the transportation of produced water to a disposal facility. The produced water will have several stages of treatment prior to storage at the proposed Pond 10 facility. When a natural gas well is drilled, water from the drilled formation is extracted along with the natural gas and classified as produced water. The produced water will contain natural gas and other products and must be treated by a separation process on the well pad. 2- and 3-phase separators will initially treat the produced water by gravity separation and skimming inside storage tanks. After the separation phase, the produced water is transported in a water hauling truck or pipeline to the centralized water facility. The Central Water Handling Facility, OXY’sAcentralizedAwaterAfacilityAtreats the produced water to remove additional solids and oil. Once the produced water has been treated it will be transported to the Pond 10 water impoundment site for storage. The water will be stored until it is required for completions activities. Anticipated completion activities will take approximately 5 days to complete. OXY will be the sole operator and user of the subject site. Oxy will install a loading/unloading station (or equivalent delivery/retrieval system) next to the multi-well/production pit, to deliver fluids or to remove fluids from the pit by truck. The loading/unloading station shall be designed and utilized to prevent hoses from being dropped into the pits and dragged over the liner, which could lead to liner damage. The loading/unloading station will be the only permitted access for manual fluids transfers to or from the pit. Vehicles will not be allowed to approach the pit any closer than the loading/unloading station. Each station will have a catch basin in case a leak occurs while operations personnel are connecting or disconnecting hoses. Signs clearly marking the truck loading/unloading station shall be provided and maintained by the operator. Pond 10 will be 1.47 acres and have a storage capacity of 90,000 barrels. Hydrocarbons on the fluid surface of the Facility will be removed and recovered within 24 hours of discovery. Recovered oil will be stored in oil tanks which will go to market for sale, while solids separated from the produced water will be disposed of in accordance with applicable COGCC regulations. Safety containment systems for Pond 10 include a geosynthetic clayAliner,AaAdoubleA60‐milAHDPEA liner system with sandwiched geonet and two site wells to check for seepage through the primary liner. The pump pad adjacent to the south edge of Pond 10 will consist of a concrete pad with an exterior lip to ensure containment in case of spills. OXY USA WTP LP Pond 10 Application Narrative Garfield County Limited Impact Review, 2014 Page 2 of 5 The Pond 10 site has been designed to mitigate potential risks to wildlife. Mitigations efforts include netting and fencing. Netting would exclude birds from entering the produced water storage impoundment and would eliminate the harming of birds protected under the Migratory Bird Protection Act. Fencing, specifically a chain link fence with 1 foot below grade and 2 feet above grade mesh prevent both large mammals (including game species) and small mammals from entering the produced water storage impoundment. The Environmental Impact Assessment is located in the Impact Analysis tab. The Wildlife Habitat Report for the water impoundment use is located in the Standards tab. The site location was previously developed as a water impoundment site. Two ponds were located on the site and will be removed prior to the installation of Pond 10. Pumps, natural gas generator, and other use specific equipment exist on site. The subject application includes previously installed equipment and structures that were previously unaddressed to bring the site into compliance with the Garfield County Land Use and Development Code. The As-Built figure is located in the Maps and Plans tab. The Pond 10 will not require personnel to be staffed at the site on a regular basis. Personnel will only be on-site during completions of a well and access the site for transportation of the produced water. A copy of the Emergency Response Plan is provided in the Maps and Plans Tab. Certifications of training can be provided upon request. The subject site will be permitted as a Centralized E&P Waste Management Facility under Colorado Oil and Gas Conservation Commission (COGCC) rules 908. Currently a Form 15 and Form 2A has been submitted to the COGCC. Copies of the COGCC applications are provided in the Supporting Documents tab. The site will be inspected regularly to identify potential conditions that could cause a release. To monitor for impacts to the subsurface at the Pond 10, three site-specific monitoring wells will be installed, two monitoring wells will be installed down gradient and one installed up-gradient. The location and sampling plan of the monitoring wells will be determined once the COGCC has reviewed the Form 28. The monitoring wells will be installed at least 20 feet below ground surface. These wells will be monitored to detect possible releases from the water impoundment operations. Proposed storage sites, an accessory to the subject application, will be located within the perimeter of the subject site. Storage site locations are identified on the Site Plan, provided in the Maps and Plans tab. Three storage sites are proposed, with Storage Site 3 strictly for the use of the proposed water impoundment. The two additional storage sites, north of the pond, are proposed for additional storage sites for the Cascade Field. Details and standards for the proposed storages sites are located in the Storage tab. A majority of the site was previously graded and developed. The site is located within the 7732 acre parcel. An access road to the site location is maintained and owned by OXY. Access roads details are located in the Standards tab. A site plan is located in the Maps and Plans tab. The construction phase will be approximately 13 weeks for the site grading and construction of the water impoundment pond. Average daily traffic during this construction period will be eight vehicles. Approximately 5 percent of these vehicles will consist of large trucks. OXY USA WTP LP Pond 10 Application Narrative Garfield County Limited Impact Review, 2014 Page 3 of 5 The traffic report determined that the increase in traffic is negligible and no significant improvements to the county roads are warranted. The site will generate 4-14 vehicles on average per daily, 33% of vehicles are classified as trucks. A traffic report is located in the Impact Analysis tab and the access route figure is located in the Maps and Plans tab. OXY will obtain all necessary permits (building, electrical, etc.) from the Garfield County Building and Planning Department as required before the start of any future construction activities at the Pond 10 site. 1.2 Purpose and Need The proposed water impoundment site will result in improved efficiency in transportation and use of produced water. The proposed site is located on OXY’sAproperty and within the Cascade Creek field. Pond 10 will support existing wells in the Cascade Creek field and the completion of future wells on Cascade Creek acreage for the Mesa, Valley, and Logan Wash areas. The Pond 10 site is critical to OXY’sAabilityAtoAproduceAnaturalAgasAinAGarfieldACounty.
