5/30/2014 | 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.

6/20/2019 | All produced fluids will be routed to new separation equipment. To protect shallow groundwater, Bonanza Creek uses separators with built-in containment. Following separation, the produced fluids will then be routed via flowline to an off-site central production facility with existing tank containment. |

6/20/2019 | Test separators and associated flow lines, 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, Bonanza Creek shall not produce the wells without an approved variance per Rule 805.b.(3)C. |

6/20/2019 | Bonanza Creek utilizes 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. |

12/16/2019 | Storm water controls have been constructed around the perimeter of the site. Stormwater controls are constructed in a manner consistenet with good engineering practices and will prevent offsite migration of sediment/contaminant. Storm water controls will remain in place until the pad is stabilized or reaches final reclamation.

12/16/2019 | All tanks are constructed within lined containment. The containment consists of a synthetic liner keyed into steel-ring berms. Containment is constructed in a manner consistent with good engineering practices to prevent migration of contaminants into the underlying soil and groundwater. |

12/16/2019 | Leak Detection Plan - Operations personnel are on location daily conducting routine operations and maintenance activity. If any leaks are to occur on site, they will be quickly identified by personnel. Operator utilizes SCADA information systems that have the ability to remotely monitor production tank levels onsite and activate specific valves, which can stop a release on location. |

12/16/2019 | Tank Battery Storage in excess of 5,200 bbls – This location is being amended to increase production facilities to allow multiple central production facilities to produce to this tank battery. Produced fluids are transported off-site through a pipeline gathering system to limit truck traffic from the location.

12/16/2019 | Waste Management- General housekeeping consists of neat and orderly storage of materials and fluids. Wastes are 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 is limited to fueling and lubrication of equipment. Any waste product from maintenance is containerized and transported offsite for disposal or recycling. There are no major equipment overhauls conducted onsite. Equipment will be transported offsite for major overhauls. Cleanup consists of patrolling the roadways, access areas, and other work areas to pick up trash, scrap debris, other discarded materials, and any contaminated soil.

12/16/2019 | Operator constructs its locations 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.

12/16/2019 | Green Completions- Test separators and associated flow lines, 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, Bonanza shall not produce the wells without an approved variance per Rule 805.b.(3)C.

12/16/2019 | Flowback Activity Containment – Operator utilizes portable containment beneath temporary produced liquid storage tanks. This protects 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.

12/16/2019 | Drilling Activity Containment – Operator utilizes 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 is vacuumed up from the liner. When drilling activity is completed, the liner is removed and transferred to the next drilling location.

12/16/2019 | Pigging Activity– Operator uses 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 will use a small containment under the receiver when removing the pig to reduce the potential for spills.

4/29/2021 | Bonanza Creek respectfully requests to add two (2) vaults under the Launcher/Receivers on the North Platte I-24 (Location ID: 429060). The proposed installation of the double walled concrete vaults will be utilized as Best Management Practice to reduce the risk of surficial oil releases when opening the launchers/receivers. Any free liquid will be drained directly into the vaults where it will be collected regularly. The vaults are fitted with steel covers that should eliminate overflow risks associated with wind or precipitation events. The steel covers will drastically reduce adverse impacts and interactions with wildlife compared to the standard use of bird netting. |
