Additionally, monthly documented leak detection and repair inspections will be conducted using an infrared (IR) camera capable of identifying leaks of hydrocarbon vapor. Any leaks discovered during these inspections will be repaired in a timely fashion, typically the same day subject to the availability of parts and other operational considerations. false f9375e9b-0b6d-4519-ae75-7374f53fe6f5 401976837 12 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 salable quality gas is achieved at each well, the gas shall be immediately directed to a sales line or shut in and conserved.

Control measures consisting of a perimeter berm and ditch flowing to a sediment trap(s) will be implemented along the western, northern, and eastern edges of the spoils and topsoil stockpiles. Cut and fill slopes will be stablized via tracking or use of tackifier. During active construction stormwater inspections will be conducted either weekly (May-Aug) or every two weeks and after significant precipitation events the (Sept-April). After active construction and interim reclamation has been completed inspections will be conducted monthly until vegetation has been re-established on the interim reclamation area. false a550c2d0-6def-4a91-9de2-d38b2f121715 401976837 6 Storm Water/Erosion Control Drip pans or liners shall be used during equipment refueling and maintenance. false 021162ef-bfd3-435b-b634-de9b8f2fda5c 401976837 14 Drilling/Completion Operations Operator will be utilizing a closed loop system. false a2abac7a-ce19-47e3-a5a2-e67de55d30cb 401976837 2 Traffic control All Traffic Plans are approved per our Road Maintenance Agreement with Weld County as part of the COA attached to the WOGLA permit. false 18cf593d-f1b4-45f7-924a-e660e7fd790b 401976837 1 Planning Four-strand barbed wire will be installed around the perimeter of location.

Excessive precipitation accumulation within secondary containment that materially impacts storage capacity of the containment structure will be removed as and discharged or disposed of properly. All structural berms, dikes, and containment will be inspected periodically to ensure they are functioning as designed. false 517fffae-c34f-47c0-8ad2-3cf987f17886 401976837 13 Odor mitigation Vapor control equipment will be installed to capture and combust all vapors emanating from storage tanks during normal operations. The facility will be equipped with a LACT unit and remote tank liquid level sensors such that tank hatches will not need to be opened during normal operations. The facility will be equipped with vapor capture systems to capture and control tank truck emissions during hydrocarbon loading activities. Hydrocarbon odors from production facilities are minimized and eliminated by keeping produced fluid hydrocarbons and natural gas contained within pipes, separators, tanks and combustors. All tanks will be sealed with thief hatches and gaskets. Tank vapors are captured with properly sized piping and combustors. false e4943a7a-af60-46a0-99a4-22c8759a7d37 401976837 11 Construction • 5,000 psi rated flanged wellhead to lubricator. Wellhead tree companion flanged to double XH fittings, schedule 80 pipe. Rated to 3,000 psi. • 3,000 psi, schedule 80, connection to separator. • 250 psi MAWP minimum, horizontal separator. All separators are internally coated and fitted with sacraficial anodes for corrosion protection. • All separators are fitted with appropriately sized PSVs, and high pressure transducer/solenoid shutdowns. ESD valve is a pneumatic kimray valve (fail close), so loss of power does not impact ESD functionality. • Secondary static pressure shutdown tied to gas meter pressure transducer. • Separator dog house gas scrubbers are fit with PSVs • Water dump lines are carbon FP-150 steel flex steel (or flex pipe) with nickel coated fittings. • Any carbon steel flanged connections are above ground. • Water and oil lines dump into oil/water tanks above ground. All storage tanks (including water) are above ground inside of containment. • All storage tanks are contained within a berm that is lined with a double poly liner. All tanks are internally coated and fitted with internal sacrificial anodes. All storage tanks are fit with PRVs and ECD pressure relief. • Locations are monitored and visually inspected daily by lease operator. • All produced water lines exiting the facility are rated to 300 psi and are fit to the same below ground specs as noted above. false 401976837 Lloyd Farms
