Groundwater and Surface Water Resources
- Closed loop (pitless) drilling systems; no reserve, drill cuttings or frac/flowback pits will be constructed
- Water used for well completions will be recycled as practicable
- Frac/Flowback tank area lined and/or tanks equipped with portable spill berm containment structures
- Production tank containment area bermed and lined with plastic
- Well pad location perimeter berms to contain unintended fluid releases
- Voluntary Water Well Testing Program
- Pre – all water wells/springs within ½ mile radius of the surface-hole location for each well on a well pad location
- Post – within one year a follow-up test on the pretest wells/springs or when all wells drilled and completed on a well pad location
- Where practical water quality testing as requested by landowner for water wells, springs, potable water and agriculture water
- Comply with provisions of water well testing in surface use agreements
- Wetland/drainage survey and mapping conducted prior to site disturbance
- Containment for well pad location within 500 feet of surface water is 110 percent secondary containment for any volume of fluids contained at a well pad location during drilling and completion operations
Planning Infrastructure and Development Activities which Minimize Impact
- Antero setbacks of 500 feet from dwelling units – COGCC setbacks are 150-200 feet
- Well pad location construction not to exceed 3.5 acres
- Bury all gas and water pipelines adjacent to roads whenever possible
- Water used for well completions will be recycled as practicable
- Above-ground facilities located to minimize visual effects (e.g. production tanks will be low profile tanks and painted to mitigate visual impacts)
Spill Prevention, Control and Countermeasure (SPCC Program)
- Annual SPCC Training
- SPCC inspections conducted quarterly
- Well pad location perimeter berms will be constructed
- Purpose is to provide tertiary spill containment for production tanks and separators
- Provides secondary spill containment for all material activities on site not just oil storage.
- Provides a barrier between well pad location activities and surrounding areas
- Frac/Flowback tank area will be located in an area with down gradient well pad location perimeter berm
- Frac/Flowback tank area lined to mitigate seepage losses from the unintended spillage of well completion fluids, or frac/flowback tanks will be placed in portable spill berms
- Standard Operating Procedures (SOPs) training performed for handling and transfer of frac/flowback and produced fluids
- High level overflow alarms installed on production tanks
- Covered drip buckets for condensate and produced water tanks and loadout lines
- Purpose is to minimize spillage and drips that occur during normal loading activities
- Designed to catch residual liquids that remain in lines after the tank valves and truck valves have been closed
- Covers minimize VOC emissions and exposure to storm water
