| Wildlife | Form: (02A )
403037904
2/15/2023 | • Operator will use Best Management Practices (BMPs) to protect wildlife in the operations area.
BMPs are but not limited to:
• The operator agrees to establish company guidelines to minimize wildlife mortality from vehicle collisions on road. Slow speed and increased awareness among employees and contractors should lessen impacts to wildlife.
• All open-vent exhaust stacks on production equipment shall be designed to prevent entry by birds and bats and to discourage nesting or perching. All tanks and above ground facilities shall be equipped with structures or devices that discourage nesting of raptors and corvids.
• The Location will be fenced if requested by the surface owner with wildlife friendly barb wire to keep livestock out of the Location if requested by the surface owner.
• The operator agrees to preclude the use of aggressive non-native grasses in habitat reclamation.
• Use remote monitoring of well production to the extent practicable
• Use topographic features and vegetative screening to create seclusion areas, where acceptable to the surface owner
• Mow or brush hog vegetation where appropriate, leaving root structure intact, instead of scraping the surface, where allowed by the surface owner. |
| Storm Water/Erosion Control | Form: (02A )
403037904
2/15/2023 | • Silt Fence: There shall be a silt fence installed around three-quarters of the location. It will be located on the north side, the northeast portion, the west side and the southwest portion of the location, to control run-on to the pad, and any stormwater flow to runoff the pad uncontrolled.
• Rock Rip-Rap: Rock rip-rap placed on both sides of the entrance road to the pad will slow/filter any stormwater runoff from the road itself.
• 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.
• Portable containment liners will be used under the drilling rig during drilling activities. The rig liner will be placed under critical wellsite components including the rig and any diesel motors. The entire location will not be lined. This liner will protect the underlying soils and vegetation from potential spills surrounding the rig during drilling and negate any topsoil clearing. Any liquid release will be vacuumed up from the liner. Upon completion of drilling activities, the liner will be removed.
• If necessary, an 18” culvert will be placed at the proposed access road into the wellpad.
• New roads will be minimally constructed until the well is drilled and tested.
o New access - ±2,011’ (2.3 acres)
o Total road for productive well - ±2,011’ x 50’ ROW = 2.3 acres
• During wellpad construction topsoil should be piled no higher than 3 to 5 feet high and slopes of the stockpiles should not exceed 2:1 (horizontal:vertical) to minimize erosion potential and facilitate interim stabilization. Perimeter control measures such as sediment control logs, rock socks, straw bales, ditch and/or berm with sediment trap(s) or sand bags will be used around the base of unstabilized stockpiles or where there is potential for sediment to come in contact with run off and leave the site
• The working pad surface area is 250’ x 170’. Please see wellsite diagrams. Topsoil material will be placed on the northwestern and southwestern portions of the cleared pad and will be approximately 1,216 CY.
• Top soil stockpiled for more than six months will be seeded and mulched with a temporary grass cover or will be stabilized using structural and/or non-structural control measures.
• To negate surface disturbance 12” x 12” test pits will be dug in the northwest corner and on the west side of the wellpad approximately at the halfway mark. The pits will be dug in a manner prior to wellpad construction so that will not require any compaction post construction.
• Training: Those persons responsible for inspections and monitoring will be trained on the contents of the Plan and the requirements herein.
• Minimize Compaction: BNL will limit traffic outside of the well pad footprint but within the disturbed area, to the extent possible, to reduce compaction.
• Stockpile Tracking: To prevent erosion, stockpiles will be tracked perpendicular to runoff direction. |
| Storm Water/Erosion Control | Form: (02A )
403037904
2/15/2023 | BNL intends to utilize the following structural control measures to control sediment migration from the facility during construction:
• Silt Fence or Straw Wattles: There shall be a perimeter silt fence installed around the northwest portion of the pad , less the entrance location, to control run-on to the pad, and any stormwater flow to runoff the pad uncontrolled.
• 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.
The surrounding topography of the location is relatively flat. As construction progresses, BMPs will be assessed, installed, and/or replaced as needed.
BNL intends to utilize the following non-structural control measures to control sediment migration from the facility during construction:
• Training: Those persons responsible for inspections and monitoring will be trained on the contents of the Plan and the requirements herein.
• Minimize Compaction: BNL will limit traffic outside of the well pad footprint but within the disturbed area, to the extent possible, to reduce compaction.
• Stockpile Tracking: To prevent erosion, stockpiles will be tracked perpendicular to runoff direction.
• Stockpile Location: Whenever possible, stockpiles will be located away from drainage system components and outfalls, and where practical, stockpiles should be placed in areas that will remain undisturbed for the longest period of time as the phases of construction progress.
BNL personnel and contractors will handle and store materials in a manner that prevents stormwater impacts and spills to the extent practicable. Where feasible, significant material storage areas will be kept covered to prevent contact with stormwater.
The following guidelines for storing and managing petroleum products will be implemented:
• Product containers will be clearly labeled.
• Drums (if present) will be kept within secondary containment or general site containment (i.e. perimeter berm), and may also need to be kept off the ground. Lids for drummed materials will be securely fastened.
• Fuel tanks will be stored within secondary containment, general site containment, or stored to minimize impacts to stormwater.
• Persons trained in handling spills will be on call at all times; BNL field personnel are trained on spill management procedures annually.
• Spill response equipment and materials (absorbent materials, shovels, etc.) will be easily accessible. Each BNL lease operator is equipped with a small spill response kit in their truck.
• Storage areas and containers will be regularly monitored for leaks and repaired or replaced as necessary.
Oily wastes such as used oil filters, empty containers, rags, and sorbent pads and socks containing oils will be placed in proper receptacles and disposed of or recycled. Routine inspections will be conducted to identify leaks from equipment and vehicles and if needed corrective actions will be implemented. |

| Interim Reclamation | Form: (02A )
403037904
2/15/2023 | • A ditch and berm created from excess topsoil material will be constructed on part of the northeastern
portion, the western portion, and a part of the southwestern portion of the Location.
• A silt fence will be installed along the perimeter of the Location.
• Rock rip-rap will be installed at the culvert at the entrance of the Location.
• The topsoil stockpile will be placed on a part of the southeastern portion, the eastern portion and part
of the southwestern portion of the Location.
• Following the drilling and completion activities, the well pad will be reduced, thus minimizing the area
of disturbance for the production life of the well. The pad will be recontoured, subsoil will be applied,
and any topsoil recovered during active construction will be applied over the subsoil. The reduced
area will be stabilized with seed, hydro-seed, bonded fiber matrix, mulch, etc. as deemed appropriate
for the site. Please see Production/Interim Reclamation Drawing.
• If weeds appear, an aggressive weed management program will be implemented. The program will
depend on if weeds appear and volume and type.
• A seed mix will be approved by the surface owner and the Colorado Parks and Wildlife prior to interim
reclamation and per their standard process.
• BNL will fence the location with wildlife friendly barb wire if requested by the surface owner to keep
livestock out of the Location.
• All earthwork for interim reclamation will be completed within six months of well completion or
plugging. Reclamation will be completed in the fall if possible; after September 15 and prior to ground
freezing. If spring seeding is necessary, seeding will be conducted after the frost leaves the ground
and no later than May 15.
• All interim reclaimed areas will be recontoured as much as possible to match the initial surrounding
topography while maintaining safe working areas. |
