All berms will be visually checked periodically to ensure proper working condition. Containment berms shall be constructed and designed to prevent leakage and resist degradation from erosion or routine operation. Tertiary containment, such as an earthen berm, will be installed as required for Production Facilities within 500 feet of a down gradient surface water feature. All berms will be visually checked periodically to ensure proper working condition. false 4dab7a0d-9b8f-4ae3-a28a-a1a3be068d23 401805353 5 Material Handling and Spill Prevention SPCC control and counter measures plans will be in place to address construction, drilling, and operations associated with oil and gas development throughout the state of Colorado prior to any construction, drilling or operations related activity. false 182ca10b-5861-44d5-8792-b6410c5eedb1 401805353 3 Storm Water/Erosion Control Implement and maintain BMP’s to control storm water runoff in a manner that minimizes erosion, transport of sediment off site, and site degradation. Co-locate gas and water gathering lines whenever feasible and mitigate any erosion problems that arise due to the constructions pf any pipelines. The SWMP in place will be in accordance with CDPHE General Permit Rules. false d938dca0-c2a0-46b8-9a16-f4a96c136105 401805353 2 General Housekeeping Equipment shall be painted with uniform, non-contracting, non-reflective color tones and with colors matched to, but slightly darker than the surrounding landscape.

The site shall be prepared in accordance with the specifications of the design package prior to tank installation; including ensuring that proper compaction requirements have been met. The MLVT will be at least 75 feet from a wellhead, fired vessel, heater-treater, or a compressor with a rating of 200 horsepower or more. It will be placed at least 50 feet from a separator, well test unit, or other non-fired equipment. All liner seams will be welded and tested in accordance with applicable ASTM international standards. Operator will be present during initial filling of the MLVT and the contractor will supervise and inspect the MLVT for leaks during filling. Operator will comply with the testing and re-inspection requirements and associated written standard operating procedures (SOP) listed on the design package. Signs will be posted on the MLVT indicating that the contents are freshwater. The MLVT will be operated with a minimum of 1 foot of freeboard at all times. Access to the MLVT will be limited to operational personnel and authorized regulatory agency personnel. Operator or contractor will conduct daily visual inspections of the exterior wall and surrounding area for integrity deficiencies. Operator will have a contingency plan/emergency response plan associated with the MLVT and it is on file at their office. A fabric reinforced liner will be utilized.
