Only materials with Material Test Reports (MTRs) provided by the pipeline supplier are used in the construction of the flowlines. Audible, Visual, and Olfactory (AVO) inspections are of the facility are conduced daily by the Operator. Any valve or fitting that is found to be ineffective is either repaired immediately or well shut-in procedures are implemented. Documented AVO inspections and optical gas imaging surveys are conduced monthly by a third-party specialist. The location will utilize a SCADA (remote monitoring) system to monitor facility pressures and flows. Sensors are placed on multiple points throughout the facility and are designed to measure the system for irregularities that would indicate a leak in the system or change in production of oil, water, or gas. The SCADA system is designed with alarms that are triggered by irregularities will activate automatic shut-in of the well and facility. If a leak is discovered or suspected, the well will be shut in and the line will be hydrotested. If a leak is determined, the well remains shut in while the leak is located and repaired. Not until the line has passed hydrotesting, will the well be brought back online. false 21c2cee2-40a5-4f6d-89d1-3f62de302402 402372267 1 General Housekeeping 804. Visual Impacts: All long term facility structures will be painted a color that enables the facilities to blend in with the natural background color of the landscape, as seen from a viewing distance and location typically used by the public. 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 7772a8e8-e5a5-4713-a849-935137429f6c 402372267 7 Interim Reclamation Operator shall be responsible for segregating the topsoil, backfilling, re-compacting any backfill, reseeding, and re-contouring the surface of any disturbed area so as not to interfere with Owner??s operations and shall reclaim such area to be returned to preexisting conditions as best as possible with control of all noxious weeds. false c6b8a482-d795-4b37-93c5-c3a88ab453b2 402372267 2 Storm Water/Erosion Control Implement and maintain BMPs to control stormwater runoff in a manner that minimizes erosion, transport of sediment offsite, and site degradation. Co-locate gathering lines to mitigate erosion problems that arise due to the construction of any pipeline(s). false 3efeb2ab-2525-406b-892d-e1fc39f75b85 402372267 5 Construction Operator will have a 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. 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. MLVT 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. MLVT will be operated with a minimum of 1 foot of freeboard at all times. Access to 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 MLVT 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. false 83ad5bd1-d274-4f48-8877-f4dd66bfaeca 402372267 6 Emissions mitigation Operator has contracted with a third party to bring a gas sales lines to the location to send salable quality gas immediately down the sales line. In the event that a sales line connection is not available upon the completion of flowback, operator will follow the policy per the Notice to Operators "Rule 912 Venting or Flaring Produced Natural Gas". All salable quality gas shall be directed to the sales line as soon as practicable or shut in and conserved in accordance with Rule 805.b.(3)B.v. false 6e54a67c-a01f-41b1-a6e6-5b6f6439f98c 402372267 3 Storm Water/Erosion Control A sediment trap will be constructed to capture any sediment prior to leaving the location. The sediment trap has been sized in accordance with good engineering practices. A temporary diversion, consisting of a cut swale and compacted earthen berm, will be constructed along the pad edge and routed to the sediment trap to prevent offsite migration of sediment/contaminant into the nearby surface water features. If necessary, check dams will be constructed within the swale. false 402372267 Clinton Neil Bashor
