9/24/2021 | Light Mitigation: Operator will install an engineered perimeter sound wall on all sides of location during all drilling and completion operations to block light from the buildings in the vicinity of the site. Light sources will be directed downward during all phases of operations. |
| Dust control | Form: (04 )
402790170
9/24/2021 | Dust mitigation measures shall include but are not limited to the use of speed restrictions, regular road maintenance, restrictions of construction activities during high wind days, and silica dust controls when handling sand used in hydraulic fracturing operations. The access road will be constructed with road base aggregate material. Additional management practices such as road surfacing, wind breaks and barriers may be used. In terms of silica dust controls when handling sand used in hydraulic fracturing operations, Operator's vendors will use an advanced Containerized Sand System for
proppant delivery, storage on location and ultimately delivery to the blender and frac
fluid system. The containers use gravity (not pneumatics) to drop sand into the
blender??s sand hopper that drastically reduces dust generation. This system also
removes people and equipment from the proppant handling operations during
fracturing treatments, considerably reducing exposures and EHS risks to individuals from dust and older sand handling equipment (like conveyor belts). Remote controls are used to open and close sand gates on the bins to further reduce silica dust exposure to workers and scales are used to weigh the boxes so people are not required to open boxes and visually inspect how much proppant is remaining. PPE is worn as required for each job/ task including respirators when exposure to silica dust require them. |

5/7/2025 | The wells drilled are using a “closed loop” mud handling system. 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.
During well stimulation, water and sand are injected into the target formation. A portion of the water and sand stay in formation during completion operations. Diesel fuel (generally) is used to power all equipment on location such as pumps, cranes, light towers, generators, etc. Any fuel that is not consumed at the end of the project will be reused elsewhere. Likewise, remaining water in frac or modular tanks that has been treated with biocide will either be used for future frac operations or pumped into trucks, removed from the Location and disposed of at a permitted water recycling/disposal facility. Flowback After conclusion of completions activity, the injected water, formation fluid and frac sand are produced by the well. The liquid and gas is separated from the sand and is produced into permanent production facilities. 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 Produced water is separated from other produced fluids via a three-phase separator and diverted to 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.
All trash will be contained in a portable, completely enclosed, wire mesh trash cage. Upon completion of the drilling operation, the trash cage will be removed and hauled to the nearest authorized sanitary landfill. A portable self-contained chemical toilet will be supplied on location for human waste temporarily during drilling and completion operations. As necessary the holding tank will be pumped and disposed of at an approved sewage facility. Garbage and the chemical toilet will be disposed of on a weekly basis.
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.
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.

5/7/2025 | Offsite sediment tracking by vehicles is a potential pollutant source to stormwater and waters of the State. To address this, POCO will install a stabilized track pad at the access road’s intersection with the nearby county road. The well pad will be surfaced with rock, as needed, to reduce sediment pick-up.
POCO intends to utilize the following structural control measures to control sediment migration from the facility during construction: • Earthen Berm: An earthen berm will be constructed along the southern boundary of the pad. Smaller berms will be constructed along portions of the northern and eastern pad boundaries. • Drainage Ditch: A drainage ditch shall be constructed along the northeast boundary of the well-pad and run in a northerly and westerly direction to direct water from an “Unnamed Ditch” around the well-pad perimeter. A second drainage ditch shall be constructed along the southern boundary of the pad in a westerly and northerly direction to direct water around the well-pad perimeter. • Sediment Control Log: A sediment control log will be placed on the southern boundary of the topsoil stockpile. • Mulch/Seed: Topsoil stockpiles that will be exposed for more than six months will be mulched and/or seeded as a stabilization technique to control sediment loss. • Sediment Control Trap: Pads with rip-pad protected outfalls designed to allow sediment to precipitate out of water and allow the water without sediment out off the property will be constructed on the northwest corner of the pad. • Vehicle Tracking Pad: Vehicle tracking pads are a type of vehicle tracking control which minimize tracking of sediments from the well pad to paved road surfaces. A vehicle tracking pad will be constructed along the access road. • Rock Check Dams: Rock check dams are temporary grade control structures placed in drainage channels to limit the erosivity of stormwater by reducing flow velocity. Rock check dams shall be constructed within the drainage ditches at the well-pad. |

5/7/2025 | DRILLING: During drilling operations, POCO keeps an accurate account of volume levels on all tanks, in particular the mud volumes in the active pits / tanks. This is done with PVT alarms to assist with monitoring overall active tank levels and ensure spills don’t occur, via surges or a severe downhole loss. When completing transfers between the tank farm to the active system or the solids control equipment, POCO will always use two people: one person will be at each end with a radio so they can communicate and don’t overfill or leave a pump running. For containment, POCO uses a liner under all drilling equipment holding oil bearing materials, distillate or diesel so leaks cannot touch the ground and are easier to identify. The liner is boarded by “duck pond” barriers to prevent a spill from leaving the lined area. Any time valves or fittings are damaged or broken, they are immediately replaced and retested to ensure proper function. Crews perform multiple inspections per day around the backyard and rig to ensure there are no spills or minor leaks on any hose, connection, or other equipment.
COMPLETIONS: During completion operations, POCO keeps an accurate account of volume levels on all tanks, and transports. Automation and alarms are used for fuel. When completing transfers between the transports, there are always two people on the transfer: one person at each end with a radio so they can communicate and don’t overfill or leave a pump running. All transfers are done on containment. For containment, POCO uses an approved and inspected liner under all completions equipment holding any type of fluid, chemical or diesel so leaks cannot touch the ground and are easier to identify. The liner is boarded by “duck pond” barriers to prevent a spill from leaving the lined area. Any time there needs to be a connection, fluid is pumped to frac tanks. The lines are then pressure tested to ensure there are no leaks when reconnected. Crews/consultants perform multiple inspections per day around the equipment the pad to ensure there are no spills or minor leaks on any hose, connection, or other equipment.
PRODUCTION: Sized secondary containment for the tank batteries and production equipment; o Containment will be sufficiently sized to contain at least 150% of the volume of the largest single tank within the containment o Containment will be designed, constructed, and installed to prevent leakage and resist degradation from erosion or routine operation o Containment will be lined with an impervious layer underlying all primary containment vessels o Secondary containment will be designed to prevent spills or releases from primary containment vessels from migrating horizontally or vertically prior to clean-up
Aboveground flowlines will be visually inspected on a weekly basis and tested triennially for leaks. Underground lines will be pressure tested every 3 years. Pressure testing records will be maintained by operator for a minimum of 10 years.
