COGIS - Conditions of Approval Results

Type	Source Document	Conditions of Approval
OGLA	Form: (02A) 400159816 05/10/2011	GENERAL SITE COAs: Operator must implement best management practices to contain any unintentional release of fluids, including any fluids conveyed via temporary surface pipelines or buried pipelines. Any pit constructed to hold fluids (reserve pit, production pit, frac pit; except for flare pit, if built) must be lined, or a closed loop system (as indicated by operator on the Form 2A) must be implemented . Operator must ensure secondary containment for any volume of fluids contained at well site during drilling and completion operations; including, but not limited to, construction of a berm or diversion dike, diversion/collection trenches within and/or outside of berms/dikes, site grading, or other comparable measures (i.e., best management practices (BMPs) associated with stormwater management) sufficiently protective of nearby surface water. Any berm constructed at the well pad location will be stabilized, inspected at regular intervals (at least every 14 days), and maintained in good condition. The moisture content of any drill cuttings in a cuttings pit, trench, or pile shall be as low as practicable to prevent accumulation of liquids greater than de minimis amounts. At the time of closure, the drill cuttings must also meet the applicable standards of table 910-1. Flowback and stimulation fluids must be sent to tanks to allow the sand to settle out before the fluids can be placed into any pipeline or pit located on the well pad. The flowback and stimulation fluid tanks must be placed on the well pad in an area with additional downgradient perimeter berming. The area where flowback fluids will be stored/reused must be constructed to be sufficiently impervious to contain any spilled or released material (per Rule 604.a.(4)). Berms or other containment devices shall be constructed in compliance with Rule 604.a.(4) around crude oil, condensate, and produced water storage tanks.
Engineer	Form: (04) 401217548 12/28/2017	1) Operator shall submit an Application for Permit to Drill, Form 2 for each preset conductor by June 1, 2018. Operator shall maintain a valid permit for each preset conductor until the well has been drilled or the conductor has been plugged.

COGIS - Best Management Practice Results

BMP Type	Source Document	Best Management Practices
Wildlife	Form: (02A ) 400159816 5/31/2011	Wildlife Mitigation Plan Supplemental Best Management Practices Antero Rifle-Silt (Gravel Trend) Leasehold – March 24, 2010 1.Drilling and Production No reserve, drill cuttings or frac/flowback pits will be constructed Well pads will be constructed with perimeter berm on downslope area Well pads, access roads will be graveled to reduce fugitive dust, sediment run-off Above-ground facilities will be located to minimize visual effects (e.g. production tanks will be low profile tanks and painted to mitigate visual impacts.) Combustor controls will be used to mitigate odors from production tanks Well completions will utilize flowback completion technologies and/or flares to reduce odors from plug drillout, and venting of salable and non-salable gas High level alarms will be installed on production tanks Production tank containment area will be lined with plastic 2.Invasive Non-Native Vegetation Control Weed management plan will be developed and implemented to monitor and control noxious and invasive weeds Noxious weed control includes three treatments per year Existing weed infestations will be mapped prior to the development of each pad, access road and pipeline when practicable Reclamation/revegetation will be used as a weed management tool 3.Planning Infrastructure and Development Activities Directional drilling will be implemented to minimize habitat loss and habitat fragmentation Remote monitoring using SCADA systems to reduce truck traffic, fugitive dust Water pipeline infrastructure will be installed concurrently with the gas pipeline infrastructure where possible. SPCC inspections will be conducted quarterly Water used for well completions will be recycled as practicable Baseline and post drilling/completion water well testing will be performed for permitted water wells within ½ mile of down-hole location Annual planning meeting to be conducted with Rifle-Silt-New Castle Community 4.Stormwater Management Facilities will be operated with a Water Quality Control Division (WQCD) stormwater construction permit. Stormwater BMPs in accordance with the Stormwater Management Plan will be implemented in a manner that minimizes erosion, transport of sediment offsite, and site degradation. Inspections will be conducted every two weeks or monthly and in accordance with WQCD General Permit to confirm that applicable BMPs are in place, maintained and functioning properly. 5.Public Water System Protection Section 317B(d) Best management practices will be implemented to contain any unintentional releases of fluids for locations within 500 feet of surface water Locations within 500 feet of surface water will ensure 110 percent secondary containment for any volume of fluids contained at a well site during drilling and completion operations 6.Mitigation Plan Best Management Practices Mitigation Plan signed by Ron Velarde, CDOW NW Regional Manager and Kevin Kilstrom, Antero Resources VP Production, on March 24, 2010. Closed loop (pitless) drilling system. Participation in raptor and other birds (great blue heron) monitoring and surveying with protocol to be developed by CDOW and implemented by Antero when practicable. Buried water and gas pipelines as means to reduce truck traffic. Seasonal raptor RSOs for species not included in new COGCC rules will be considered where practicable. Avoidance/seclusion area in the northeast corner of the CDP (Burning Mountain) unless lease expiration warrants development. Restricted rig operation to less than 2 per section within the big game seclusion areas during the winter (to be determined in consultation with CDOW). Maintaining a ¼ mile no surface occupancy buffer around active bald eagle nests. New pad construction not to exceed 3 acres. Pad density not to exceed 1 pad per 120 acres. Bury all gas and water pipelines adjacent to roads whenever possible. The mitigation opportunities/projects will be defined by the Mitigation Plan for each well pad. The mitigation opportunities/projects will be determined cooperatively with the CDOW during the annual Antero Mitigation Plan Review. CDOW Actions to Minimize Adverse Impacts to Wildlife Resources is attached to the March 22, 2010 Mitigation Plan
