8/29/2014 | The following procedure describes BCEI standard construction practices for setting a partially buried pre-cast cement water vault and new tank battery construction.
1) The excavation will first be lined with 4” of clay or other low permeability soil.
2) A 30 mil liner will be installed on top of the low permeability soil. The 30 mil liner will be a contiguous liner which will underlay the entire tank battery.
3) The tank battery / water vault liner will be keyed into a galvanized steel containment ring installed surrounding the tank battery.
4) Sand bedding will be installed to protect the synthetic liner prior to placing equipment in the containment area.

6/25/2020 | Development from existing well pads - Operator has planned the expansion of an existing location to minimize impacts to neighbors and the enviornment by reducing surface distubance. |
| General Housekeeping | Form: (02A )
402090153
6/25/2020 | Waste Management- General housekeeping will consist of neat and orderly storage of materials and fluids. Wastes will be temporarily stored in sealed containers and regularly collected and disposed of at offsite, permitted facilities. If spills occur, cleanup will be implemented within 24-48 hours, as appropriate, to minimize any commingling of waste materials with storm water runoff. Routine maintenance will be limited to fueling and lubrication of equipment. Any waste product from maintenance will be containerized and transported offsite for disposal or recycling. There will be no major equipment overhauls conducted onsite. Equipment will be transported offsite for major overhauls. Cleanup will consist of patrolling the roadways, access areas, and other work areas to pick up trash, scrap debris, other discarded materials, and any contaminated soil. |
| Storm Water/Erosion Control | Form: (02A )
402090153
6/25/2020 | Storm Water Control - Operator shall construct storm water controls around the perimeter of the site prior to construction. Typically, Operator utilizes a ditch and berm system of storm water controls on location. BMP’s design is finalized just prior to construction by a third party storm water contractor and may vary according to the location. Storm water controls will remain in place until the pad is stabilized or reaches final reclamation. |

6/25/2020 | Flowback Activity Containment – Operator shall utilize portable containment beneath temporary produced liquid storage tanks. This will protect shallow groundwater from any potential spills during completions activity. When flowback activity is complete, the containment and temporary produced liquid storage tanks will be removed and transferred to the next location. |
| Material Handling and Spill Prevention | Form: (02A )
402090153
6/25/2020 | Completions Activity Containment – Operator will utilize portable containment beneath the liquid storage and mixing equipment. Containment will be constructed in a manner consistent with good engineering practices to prevent migration of contaminants into the underlying soil and groundwater. |
| Material Handling and Spill Prevention | Form: (02A )
402090153
6/25/2020 | Drilling Activity Containment – Operator shall utilize a portable containment liner under the drilling rig during drilling activities. This protects shallow groundwater from any potential spills surrounding the rig during drilling. A liquid release would simply be vacuumed up from the liner. When drilling activity is completed, the liner is removed and transferred to the next drilling location. |

402090153
6/25/2020 | Separation Equipment Containment - To protect shallow groundwater, Operator shall use separators with built-in containment. |

402090153
6/25/2020 | Leak Detection Plan- Operator shall have personnel on location daily conducting routine operations and maintenance activity. If any leaks occur on site, they will be quickly identified and mitigated by operator's personnel. Operator shall use SCADA information systems that have the ability to remotely monitor production tanks onsite and shut in wells to stop a fluid release during upset conditions. In addition to daily operations and maintenance performed at the location, operator shall conduct required inspections for SPCC, Stormwater, and LDAR compliance. |
| Material Handling and Spill Prevention | Form: (02A )
402090153
6/25/2020 | Pigging Activity– Operator shall conduct closed loop pigging to maintain flowlines. This practice removes deposits in flowlines without open-ended liquid collection. The deposits are flushed through the active flowlines to the production equipment. This practice reduces the potential for releases and emissions related to open loop methods. Operator shall use a small containment under the receiver when removing the pig to reduce the potential for spills. |

402090153
6/25/2020 | Maintenance Tank Containment – Operator shall construct maintenance tanks inside lined containment. The containment will be constructed to hold the entire contents of the maintenance tank in the event of a potential fluid release. |

402090153
6/25/2020 | Construction – Operator shall construct this location with a compacted road base surface. This surface is at least 4 inches thick and compacted to prevent surface degradation from drilling and production activity and traffic. This layer of road base protects shallow groundwater by containing liquids and preventing vertical migration of a potential spill. |

6/25/2020 | Green Completions (Rule 604.c.(2)C.) - Operator shall install test separators, associated flow lines, sand traps, and emission control systems 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, Operator shall not produce the wells without an approved variance per Rule 805.b.(3)C. |

10/18/2022 | All operations previously delayed due to BUOW presence; CPW consulted/concurred regarding delay. Third party biologists will confirm owls are no longer present prior to operations. Previously consulted on 10/5/22 for pump repair job on same well pad. |

10/18/2022 | If operations occur during the pronghorn winter season, operations will be restricted to 2 hours post-sunrise to 2 hours pre-sunset between Jan 1 - Apr 30.(Operator will try to schedule operations outside pronghorn winter season; however, avoidance of burrowing owl nesting season is higher priority for this particular location.) |
