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. false e3d16c2b-463a-4bde-ae3a-3f823b72665e 402008729 14 Drilling/Completion Operations 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, Bonanza Creek shall not produce the wells without an approved variance per Rule 805.b.(3)C. false 723bb889-e57d-46f7-9016-500989b90d09 402008729 7 Material Handling and Spill Prevention 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. false e2a9ca6d-e049-4d8b-bffd-55c0c5e62edb 402008729 17 Drilling/Completion Operations 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. false 1d4462ec-61f4-4ae6-b9a5-5d0688a8710d 402008729 10 Material Handling and Spill Prevention Monitoring Wells: Operator shall install one cross- and one down-gradient monitoring well in order to monitor and confirm that shallow groundwater has not been impacted by onsite activity. Monitoring wells will be installed and initial samples collected prior to well spud. Operator shall collect groundwater samples from each monitoring well semi-annually and analyze each sample for benzene, toluene, ethylbenzene, and total xylenes. If a release threatens to impact shallow groundwater, Operator shall collect groundwater samples from each well within 60 days of the release if a semi-annual monitoring event is not already scheduled. false dca326a3-468b-4368-9a9f-5d3ae1f99b06 402008729 5 Material Handling and Spill Prevention Separation Equipment Containment - Operator shall use separators with built-in containment to protect shallow groundwater, . false 455b76dc-89eb-4d27-aaad-636ce8cc54b4 402008729 15 Drilling/Completion Operations 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. false 06f04cdb-79d8-411e-8287-63e79260e219 402008729 12 Construction 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. false 91acc781-78b3-4b46-b8ba-6ebf8293479e 402008729 9 Material Handling and Spill Prevention 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. false fc1b406d-c4be-4881-b767-7fed0dffb6c6 402008729 2 Storm Water/Erosion Control Storm Water Control - Storm water controls will be constructed 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 used are determined 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 reaches final reclamation. false 3e1d5b55-0cd5-4ad3-be4a-958a367cb990 402008729 4 Material Handling and Spill Prevention Pipeline Protection- Operator Shall use protective barriers at pipeline risers when they are adjacent to areas with onsite traffic. false 6a162e04-91e0-4b1c-b403-a4fb47e2c914 402008729 16 Drilling/Completion Operations 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. false 79233281-f06f-46db-82a5-b18d587edaa0 402008729 8 Material Handling and Spill Prevention Removal of Onsite Produced Fluid Storage - To protect shallow groundwater and nearby surface water, Operator shall transfer, via flowlines, produced fluids to an offsite location for storage or final transportation to sales/disposal. This does not include the maintenance tank which is for well maintenance and only stores produced fluid temporarily for final disposal. false 8fa56efa-6300-423e-8433-ddc8ebb3d51e 402008729 3 Storm Water/Erosion Control Site Specific Storm Water Control - Due to the proximity of an adjacent surface water feature, Operator will install erosion control blankets on the disturbed (non-stabilized) areas. This additional control will significantly reduce the potential for wind and water erosion of the disturbed areas on location. false b4ea8272-9a22-4729-bd49-e33bf2fb59eb 402008729 11 Material Handling and Spill Prevention Offsite Produced Liquid Storage – To further reduce the risk of release, Operator will route all produced fluids offsite to a central production facility outside the floodplain approx. 9800-ft SE of the proposed Pronghorn 13-30 well location. false 46deac0a-eb21-4fcb-bf6d-ea06f3654c1f 402008729 6 Material Handling and Spill Prevention 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 well production 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 . false eff0b9f7-1c07-4061-9b9a-feb9e17bbe52 402008729 13 Drilling/Completion Operations Closed Loop Drilling - Operator shall utilize a closed loop drilling system false 402008729 The Riverside Club
