4/7/2023 | A combination of wattles and a ditch will be implemented around the perimeter of the site in downsloping areas prior to earth disturbing activities taking place. The wattles will be the primary control measure installed until the pad is constructed and the associated ditch and basins can be completed. The sediment basins will have a spillway and a riprap apron outlet and will be installed on the west side of the pad and the northeast side of the pad. Diversion ditches will maintain positive drainage to the sediment basins to inhibit pooling within the ditch.
Sculpted slopes and berms will have seed & mulch, typically a tackifier, applied to provide resistance to erosion. Additionally, any area that is at final grade or not worked during 14 consecutive days will receive temporary stabilization methods, such as the tackifier application.
For the purposes of this location, inspections will be conducted every 14 calendar days and within 24 hours after the end of any precipitation or snowmelt event that causes surface erosion for active construction sites and up to 72 hours after the end of any precipitation or snowmelt event that causes surface erosion for sites that may be temporarily idle, but prior to re-commencing construction activities. Provided the timing is appropriate, the post-storm inspections may be used to fulfill the 14-day routine inspection requirement. Sites that have been completed and are awaiting establishment of vegetation will be on a 30-day inspection schedule where post-storm event inspections are not required.
A Post-construction Stormwater Program will be incorporated into the GMT Drilling Program following the guidelines set forth in COGCC Rule 1002.f.(3), except that such requirements are not applicable to Tier 1 oil and gas locations. Sites located in agricultural fields are not subject to these requirements but are instead measured against stunted crops and subsidence for compaction issues. Post-construction inspections are conducted annually unless more frequent inspections are deemed necessary. |

| Interim Reclamation | Form: (02A )
403090768
4/7/2023 | In areas that are disturbed by construction, topsoil will be stripped and stockpiled near the site. All brush, limbs, and other woody material will be stockpiled separately from the topsoil. Soil materials will be managed so that erosion and sediment transport are minimized. Nearby drainages will be protected by appropriate measures.
The salvaging and spreading of topsoil will not be performed when the ground or topsoil is frozen or too wet to adequately support construction equipment. If such equipment creates ruts in excess of four inches deep, the soil will be deemed too wet.
All earthwork for interim reclamation will be completed within six months of well completion or plugging (weather permitting). In areas that will not be drill-seeded, the seed mix will be broadcast-seeded at twice the application rate shown and covered 0.25 to 0.5 inches deep with a harrow or drag bar or will be broadcast-seeded into imprints, such as fresh dozer cleat marks.
Initial seedbed preparation will consist of backfilling, leveling, and ripping all compacted areas. Final seedbed preparation will consist of contour cultivating to a depth up to twelve inches within 24 hours prior to seeding. Seeding will be conducted no more than 24 hours following completion of final seedbed preparation. A certified weed-free seed as agreed upon with the private surface owner to meet reclamation standards will be used. The seed mix will be used on all disturbed surfaces.
Revegetation will be accomplished by planting a seed mix as agreed upon by the private surface owner. The seed mix will include a portion of vegetation occurring in the surrounding natural vegetation.
No seeding will occur from May 15 to September 15. Fall seeding is preferred and will be conducted after September 15 and prior to ground freezing. Spring seeding will be conducted after the frost leaves the ground and no later than May 15.
Annual or noxious weeds shall be controlled on all disturbed areas as directed by the private surface owner. An intensive weed monitoring and control program will be implemented beginning the first growing season after interim reclamation. Noxious weeds that have been identified during monitoring will be promptly treated and controlled. All reclamation equipment will be cleaned prior to use to reduce the potential for introduction of noxious weeds or other undesirable non-native species. The operator will coordinate all weed and insect control measures with state and/or local management agencies.
Reclaimed areas will be monitored annually. Actions will be taken to ensure that reclamation standards
are met as quickly as reasonably practical.
Traveled portion of production site will be gravel surfaced upon completion of production facility installation and prior to production.
Additional surface material will be obtained from commercial sources or an approved borrow area.
Construction and maintenance will not be performed when the ground or topsoil is frozen or too wet to adequately support construction equipment. If such equipment creates ruts in excess of four (4) inches deep, the soil will be
deemed too wet.
The wellpad 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, hydroseed, bonded fiber matrix, mulch, etc. as deemed appropriate for the site.
Any gathering line corridors will be contained within the working pad surface and will be reclaimed leaving only operational areas where necessary. Topsoil will be reapplied during interim reclamation to promote regrowth of vegetation.
Continual interim reclamation stabilization controls will be used during both active and post construction until permanent vegetation is established.
A wildlife fence is planned around the entire Location. Fencing will negate grazing of new vegetation and will reduce foot compaction by animals. |

4/7/2023 | During construction and development topsoil stockpiles should not exceed 3:1 (horizontal:vertical) to minimize erosion potential and facilitate interim stabilization.
Seeding and mulching on the western portion of the location will occur during interim reclamation to minimize the disturbed area to protect the topsoil and negate additional soil erosion.
Gravel will be installed on the wellpad and access road. Any area not needed for production activities will be interim reclaimed. |

4/7/2023 | One (1) 12” x 12” topsoil test pit will be hand dug in each quadrant to determine topsoil depth. Topsoil depth is not anticipated to be any deeper than twelve inches.
Access road and wellpad construction will be performed using conventional cut and fill construction. To the extent feasible, surface vegetation would be cleared by mowing, raking, and burning in preference to scraping to facilitate topsoil stabilization and reclamation potential. GMT will begin with the clearing of vegetation and removal of available topsoil material to a depth of 12 inches or maximum available.
Twelve (12) inches of topsoil (or maximum available) including the remaining vegetative materials will be bladed across the construction ROW and moved to the down-gradient side of the ROW for temporary storage as a linear storage berm. |
| Final Reclamation | Form: (02A )
403090768
4/7/2023 | A portion of the topsoil stockpile will be seeded and mulched and used in final reclamation.
Topsoil 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. |
