All records will be kept readily available. false c938b30f-a728-4dbd-89d4-2d0de7d08f02 402405742 8 Emissions mitigation 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, the operator shall not produce the wells without an approved variance per Rule 805.b. (3)C. false 737e8c8f-eedb-419b-bf6d-547bbf16c72f 402405742 9 Emissions mitigation Tanks and all visible pipelines and valves etc. are inspected daily by company lease operators or contract operators, when possible. In addition, Bison Oil & Gas II conducts formal annual spill prevention inspections, and formal site-specific audits by third-party consultants to inspect for general site conditions as well as visible inspections for the condition of tanks, pipelines, and containment structures. Company lease operators and Production staff review production records, including volumes and pressures, looking for irregularities that may indicate a problem with a tank or pipeline. If an irregularity is detected that may indicate a potential release the suspect tank and/or pipeline(s) are removed from service, isolated, and either pressure tested or visibly inspected for indications of a potential leak. false 4f6f980e-67ef-4d62-946a-773c3005472d 402405742 4 Material Handling and Spill Prevention Operator shall install a 30mil reinforced polyethylene liner, or liner of comparable material, under the drilling rig and associated equipment for use during drilling operations. false 52bd4916-3f21-4fd5-bb9c-7ca352383319 402405742 1 General Housekeeping 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. Site will have unused equipment, trash and junk removed immediately. false 6a164748-a82a-482c-8e4a-8833c2022c0f 402405742 3 Material Handling and Spill Prevention Tank berms shall be constructed of steel walls with an engineered synthetic liner and designed to contain 100% of the capacity of the largest tank (or manifolded tanks) with the addition of rain water and additional freeboard to account for any small piping or equipment that may be in containment. Operator will place separators within secondary containment composed of steel berms with a minimum containment capacity of 100% of the single largest storage vessel inside the containment. The engineered secondary containment system will be constructed of a perimeter of walls around a flexible geotextile base. All components will then be sprayed with a polyurea liner technology or covered with an equivalent synthetic or engineered liner. This liner technology maintains impermeability and puncture resistance under exposure to UV rays, weather extremes, and chemicals commonly encountered in oil and natural gas production, and provides protection of the liner seams. All berms will be visually checked weekly to ensure proper working condition false 34b8abb1-b668-42f2-b0f0-a87b417bab5c 402405742 5 Material Handling and Spill Prevention Operator shall use a Supervisory Control and Data Acquisition (SCADA) system in conjunction with tank level indicators which have the ability to automatically shut in wells during an upset condition. false fdc4b161-3319-4d70-b15e-abd7c06f183e 402405742 12 Drilling/Completion Operations Operator has 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 or designated company representative 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 has developed a contingency plan/emergency response plan associated with the MLVT and it is on file at their office. 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 false 83d1c8eb-31b1-4b37-b2f3-beb602f20bbd 402405742 11 Odor mitigation Drilling rig and completion equipment engine exhaust will be directed away from occupied buildings to assist in mitigating potential odors. Sealed tanks with pressure relief valves and emissions controls will be utilized for the production phase. Bison Oil & Gas II will use an invert-based drilling fluid with diesel or a similar fluid for the base oil. If odor complaints are received and it is determined that they are caused by the invert drilling fluid, then an odor neutralizing agent or similar product will be added to the mud system to eliminate the odor. Cuttings are removed daily, with the exception being conductor hole cuttings which remain on location to be used as dry mix for the wet cuttings. false ff7a09a7-dbcb-4c5d-bf5d-d0268998cdde 402405742 2 Storm Water/Erosion Control Storm water controls will be constructed around the perimeter of the site prior to construction. Typically, Bison Oil & Gas II utilizes a ditch and berm system of storm water control at its sites. BMPs used are determined prior to construction and may vary according to the location. Storm water controls will remain in place until the pad is stabilized or reaches final reclamation. false 784c896b-c0d3-44a0-89f2-e3a5d6923cc5 402405742 6 Dust control Practices for control of fugitive dust caused by operations may include but are not limited to treating- roads and location with water, the use of speed restrictions, regular road maintenance, and silica dust controls when handling sand used in hydraulic fracturing operations. false aef44065-7667-4093-9af5-04133daf1ba6 402405742 7 Construction Any temporary or permanent lighting installed on location shall be directed downward to illuminate key areas within the facility, while minimizing the amount of light projected outside the facility. false 402405742 Joe & Anni Ross
