9/29/2022 | If development is proposed to occur in a prairie dog colony that has been active within the past 10 years, CPW recommends the adherence to CPW’s Burrowing Owl survey protocol if development occurs during the spring or summer months (Feb 1 to Aug 31). If nesting burrowing owls are present, no human encroachment or surface disturbance should occur within a 660-foot buffer of nesting burrows from March 1 to August 31. If burrowing owls occupy the site, CPW recommends that earthmoving and other disturbance activities be delayed until late fall after they have migrated.
If there is suitable nesting for Mountain Plover habitat on site and the initial site disturbance is planned to occur between April and August CPW recommends the lessee survey suitable nesting habitat using USFWS protocols and any active mountain plover nests should be flagged. CPW recommends no surface disturbance (other than existing agricultural activities) within 300 feet of active nest sites until young are hatched, independent, and fledged (April 1 - August 15).
To minimize the impact of future oil and gas development on occupied, high quality swift fox habitat, CPW recommends the Operator coordinate pre-construction survey locations for active den sites with CPW. CPW also recommends no human encroachment, surface disturbance, or construction activity within 0.25-mile of an active maternal den site from March 15 through June 15. |

9/29/2022 | 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 ungulates out of the Location. |

9/29/2022 | Earthen Swale: An earthen swale shall be constructed around the east and partially south side of the pad to direct any surface run-on around the pad and away from any construction disturbance.
Silt Fence: There shall be a perimeter silt fence installed around the entire 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.
Sediment traps will be constructed on the northeast and southeast corners of the wellpad. |

9/29/2022 | Daily audio, visual, and olfactory (AVO) inspection of all above ground facilities.
Daily production monitoring.
Approved Instrument Monitoring Method (AIMM) Inspections with “FLIR” technology Camera on a bi-monthly basis and at other times as needed and appropriate.
Audio and visual inspections twice daily during drilling and completion operations.
Load out lines and valves are located within the containment. At those facilities where the load out is not completely within the containment, the piping is sloped back towards the tank or vessel as a spill prevention and control method.
Drip pans and load line buckets must be adequately sized to contain all discharge, drips and leaks inside the containment system.
Drip pans and load line buckets must be inspected by the Lease Operators on routine rounds and emptied as needed. |

9/29/2022 | Air drilled cuttings will be collected inside a partially buried laydown open top steel cuttings tank located immediately adjacent to the end of the rig’s blooey line. The placement of the tank will include first stripping and stockpiling all topsoil in the construction of an approximate 12 feet wide by 30 feet long opening that is up to 6 feet deep. This opening will include secondary containment berms completing surrounding the opening. The opening will then be lined with 130-mil rig liner before placing the temporary partially buried laydown open top steel cuttings tank into position. |

9/29/2022 | There will be no staging, refueling, or chemical storage areas on location.
Potential pollutants located onsite will be sealed, wrapped, covered when not in use so as to eliminate or minimize contact with stormwater runoff.
Proper storage, safe-handling, good housekeeping and spill prevention practices will be use to prevent pollutants from leaving the site.
During construction, disturbed slopes will be covered with coconut blankets, straw mulch, or straw waddles and maintained for the life of the project or until slopes are stabilized and revegetated.
With appropriate landowner authorization, baseline water quality samples will be collected from agency-approved water wells in the vicinity of the proposed oil and gas location. |

9/29/2022 | BNL will use a 130-mil rig liner during the drilling and testing of the well. The rig liner will be placed under critical wellsite components including the rig and any diesel motors. The entire location will not be lined. The wellpad will be constructed to a minimum size to accommodate all equipment but allowing for maximum safety precautions. The rig mat will eliminate fugitive dust from the wellpad.
Utilize existing vegetation, trees slash or brush piles to cover disturbed areas not used for vehicle traffic.
Application of fresh water during dry season.
Applications of approved chemicals may be applied to areas not needed for traffic to form a less erodible soil.
Operations will be confined to the wellpad working surface.
Continuous monitoring of disturbed areas to evaluate additional BMPs needed.
Fresh water application to disturbed areas during construction.
Fresh water or magnesium chloride application to graveled surfaced of the Location and associated roads.
Regular road maintenance such as grading and adding additional gravel as needed. |

A freshwater mud system will be used for surface hole.
Drill pipe will be wiped to remove residual mud upon tripping out of the hole. |
| Interim Reclamation | Form: (02A )
402880799
9/29/2022 | 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.
A seed mix will be approved by Colorado State Land Board and the Colorado Parks and Wildlife prior to interim reclamation and per their standard process.
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. |
