12/10/2020 | Equipment shall be painted with uniform, non-contracting, non-reflective color tones and with colors matched to, but slightly darker than the surrounding landscape. Operator will maintain appearance with garbage clean up. A trash bin will be located on site to accumulate waste by the personnel drilling the wells. Any trash or unused equipment will be removed immediately. Operator will maintain the surface area and access roads free of trash, debris, and noxious weeds. |

12/10/2020 | Operator will implement and maintain Best Management Practices, including diversion ditches, sediment basins, and ponds as indicated on the construction layout drawings, to control stormwater runoff in a manner that minimizes erosion, transport of sediment off-site, and site degradation. The operator will co-locate gas and water gathering pipelines whenever feasible and will mitigate any erosion problems that arise due to the construction of any pipelines. Secondary containment will be installed around separators and treaters consisting of metal berm walls. The separators and treaters will be set on top of compacted road base.
During drilling and completions operations a temporary impermeable synthetic or geosynthetic liner will be utilized under the drilling rig, mud tanks, shakers, and drill cuttings bins. This liner will be installed to provide an additional layer of protection against spills. Secondary containment devices, such as duck ponds or equivalent type products, will be used to protect any pipe connections or equipment that carry, mix, or have the potential to leak fluids or chemicals. |

12/10/2020 | All material that is considered a fire hazard shall be a minimum of 25’ from the wellhead. Electrical equipment will comply with the current national electrical code. Flammable liquids shall not be stored within fifty (50) feet of the wellbore, except for the fuel in the tanks of operating equipment or supply for injection pumps. Where terrain and location configuration do not permit maintaining this distance, equivalent safety measures should be taken. |

12/10/2020 | Operator will have an MLVT Design Package, certified and sealed by a licensed professional engineer, which is on file in their office and available upon request. 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. In the event that a tank breach were to occur, the fabric reinforced liner will prevent a “zippering” failure from occurring. The liner will meet the specifications per the design package.
Operator acknowledges and will comply with the Colorado Oil & Gas Conservation Commission Policy on the Use of Modular Large Volume Tanks in Colorado dated June 13, 2014. |

12/10/2020 | Tank berms shall be constructed of steel rings with a synthetic or engineered liner and designed to contain 150% of the capacity of the largest tank. 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. Tanks will be designed, constructed, and maintained in accordance with NFPA Code 30. The tanks and berms will be visually inspected once a day for issues, and recorded inspections will be conducted once a month. |

12/10/2020 | Green Completions - Flow lines, separators, sand traps, and emission control systems shall be installed on-site to accommodate green completions techniques. When commercial quantities of salable quality gas are achieved at each well, the gas shall be immediately directed to a sales line or shut in and conserved. If a sales line is unavailable or other conditions prevent placing the gas into a sales line, the operator shall not produce the wells without an approved variance per Rule 805.b. (3)C. |

12/10/2020 | Except gas flared or vented during an upset condition, purging operations, or emergency situations, no gas shall be flared during the ozone peak season of June 1 – August 31.
To reduce the BTU content of the natural gas that is flared a Mechanical Refrigeration Unit skid will be utilized at this location, for as long as the gas is being flared, until such time that the Well is connected to a sales line. |
