8/5/2017 | Leak Detection Plan: To ensure protection for the surface during fracturing treatment, the location will be specifically constructed to contain any releases or spills. All containment will be steel with impermeable barriers installed inside and along the internal sidewalks of the containment. Volume capacity will be 110% or greater of the largest tank plus largest annual rainfall. The majority of the product will be piped out of the location.
Leak detection will be monitored by daily operator inspections and remote hi/lo pressure monitoring with electronic shut down functionality. Secondary containment from any chemical spills or leaks will surround any trucks that carry, mix, or add chemicals to the flow stream as well as connections that could possibly leak fluid. Should any spill or release occur, every reasonable step will be taken to quickly remediate the area disturbed. One to seven inspections per week will be recorded and kept in the district office and available to regulatory agencies. Records will be kept electronically indefinitely. All tanks will have hi level shut down for all producing wells on the pad.
Both gas and oil will be sold via pipeline and consequently will have remote ESD system functionality and independently tied to the operational status of the purchasing line(s) as well as high pressure ESD for all lines and vessels.
Flowlines will either be welded or threaded, some lines may be non-metallic. Welded Flowlines will be installed with welded or flanged connections. All threaded metallic pipe will be joined with appropriate lubricant/sealant. All non-metallic pipes that require welded joints will be installed with appropriate equipment to meet manufacturer recommendations and welded with qualified welders. All buried non-metal Flowline installation will contain a continuous metallic tracer line attached to the pipeline with surface access or other means of surface location. All flowlines will be pressure tested to their maximum manufactured value (at minimum 70%) prior to hydrocarbon production use. 10% of welds will be x-rayed for integrity. Chemical inspection program begins as soon as well begins flowback. A contractor for PetroShare will perform daily flowline inspections to ensure flowline integrity and prevent leaks/spills. Records of inspections will be available to COGCC upon request.

11/29/2023 | Waste Management
Drilling:
The water-based drilling fluid is reused for each surface casing borehole on a well pad. Oil-based drilling fluid can be recycled much longer than water-based drilling fluid. Drill Cuttings are stored in an above ground container and hauled offsite. Drill cuttings are mechanically separated and stored in a 20-cubicyard metal roll-off container. The cuttings are transferred from the roll-off container to a transport truck and hauled to a permitted disposal facility.
Flowback:
Recovered flowback fluids are then transported to a permitted water recycling/disposal facility
via vacuum truck or transport tanker truck. The sand is hauled offsite as a solid and disposed of at an
approved waste disposal facility.
Production:
Produced water is separated from other produced fluids via a three-phase separator and diverted to a steel produced water storage vessels. Produced water storage tanks are emptied on a routine basis and the produced water is transported to a permitted water recycling/disposal facility via vacuum truck or transport tanker truck. Produced water is transported to a permitted recycling/disposal facility under waste manifest to ensure chain of custody control.
Liquid waste consisting of sand/bacteria/water, resulting from cleaning an oil production tank or produced water tank, is transferred via hydro-vac truck to a permitted water recycling/disposal facility via vacuum truck or transport tanker truck. Liquid waste is transported to permitted recycling/disposal facilities under waste manifest to ensure chain of custody control. Solid waste at the bottom of oil production tanks and produced water tanks, including, but not limited to, sand, sludge, and other solids, is transported to a permitted disposal facility via transport truck. Solid waste is transported to permitted disposal facilities under waste manifest to ensure chain of custody control.
Spills: General housekeeping of production facilities, including cleanup of limited drips and spills, may generate small quantities of exploration and production (E&P) exempt impacted soil and/or gravel. This includes soil or gravel from secondary containment. The covered waste containers are emptied on an as needed basis. The impacted soil/gravel is transported to a permitted disposal facility under waste manifest to ensure chain of custody control. Storage/disposal is only related to housekeeping activities and is not meant for large release cleanup or remediation. |
