1/24/2020 | Prior to submittal of the Application for Permit to Drill (BLM-APD/COGCC-Form 2) and the Oil and Gas Location Assessment (COGCC-Form 2A), TEP conducted onsites and meetings with the Bureau of Land Management (BLM), Colorado Parks and Wildlife, COGCC, and the associated private landowners. These onsites and meetings were held to discuss TEP’s proposed development plan for the GR 12-29 pad and associated support facilities. Changes were made to the proposed development plan based on feedback received from all stakeholders and included in the APD.
The development plan for the GR 12-29 pad was prepared to minimize surface impacts to the greatest extent possible through the development of multiple wells from one location by utilizing directional drilling technology, co-locating access road and utilities corridors within the same area, and through the transportation of fluids to a centralized storage location at the GM Chevron Tank Facility (Fac ID #452926) and the Starkey Production Pit (Fac ID #414554) minimizing the surface area needed to conduct operations on the GR 12-29 pad location. |

1/24/2020 | Prior to commencement of construction activities, TEP will hold a pre-construction meeting with contractors to review proposed construction activities and installation of stormwater control measures. The site will be staked for construction prior to a pre-construction meeting. Staking will identify the boundaries of the proposed site to protect existing vegetation in areas that should not be disturbed. |

1/24/2020 | Storage of material and fluids on location during drilling, completion, and production operations will be conducted in a neat and orderly manner with regards to potential fire hazards on site. All garbage and trash will be stored in enclosed bear proof trash containers and transported to an approved disposal facility periodically and upon completion of construction, drilling, and completion operations on the location. No garbage or trash will be disposed of on location. The well site and access road will be kept free of trash and debris at all time. Disposal of garbage and trash will occur approximately once per week during drilling and completions operations. |
| Wildlife | Form: (02A )
401991715
1/24/2020 | The GR 12-29 pad is located within Mule Deer Critical Winter Range sensitive wildlife habitat boundary as currently mapped per COGCC geospatial data. The access road to the GR 12-29 pad traverses through Mule Deer Critical Winter Range and Elk Winter Concentration Area sensitive wildlife habitat as currently mapped per COGCC geospatial data. To minimize the potential for wildlife related traffic accidents, TEP has implemented speed restrictions for all lease roads, and requires that all TEP employees and contractors adhere to these posted speed restrictions. TEP has consulted with CPW and BLM and will be providing compensatory mitigation to offset impact to wildlife (including Mule Deer) for operation which may occur within the Big Game Winter Range Timing Limitation (BLM lease stipulation), beginning January 1st and ending March 1st annually. Please see CPW Correspondence attached to the APD for additional details.
TEP agrees to report any bear conflicts immediately to CPW. TEP will implement COGCC Rule 1204.a.1 by utilizing bear proof dumpsters and trash receptacles for all food related trash. TEP will preclude from the use of aggressive CPW-identified non-native grasses and shrubs in mule deer and elk habitat and will reclaim the site using CPW-identified native shrubs, grasses and forbs appropriate to the ecological site disturbed. |
| Storm Water/Erosion Control | Form: (02A )
401991715
1/24/2020 | Stormwater BMP’s will be in place during all phases of development to control stormwater runoff in a manner that minimizes erosion, transportation of sediment offsite, and site degradation. Stormwater BMP’s will include perimeter controls such as sediment traps, diversion ditches, check dams, waddles, and others control measures necessary to control stormwater run-on and run-off and minimized offsite movement of sediment. Stormwater BMP’s will also include site degradation control measures such as grading, slope stabilization methods (i.e. seeding, mulching, surface roughening), perimeter berms, surfacing materials (i.e. gravel), and others necessary to minimize site degradation. Stormwater controls will be installed with consideration given to worker safety, wildlife, and site access. A post-construction stormwater program will be developed for the facility as required per Rule 1002.f.(3). Stormwater is also addressed under a field-wide Stormwater Management Plan (CDPHE Certification COR404626). See the construction layout for the planned stormwater BMP’s proposed for installation at the site for further details. |
| Dust control | Form: (02A )
401991715
1/24/2020 | Fugitive dust control measures will be employed during all phase of development to minimize dust pollution. Dust control measures include but are not limited to the application of fresh water via water truck along access road during construction, drilling, and completion operations, speed restrictions, periodic road maintenance, road surfacing (i.e. gravel), and automation of wells to reduce truck traffic. Dust control measures will be employed on an as needed based during all phases of development. |
| Construction | Form: (02A )
401991715
1/24/2020 | All construction equipment and materials will be contained within the proposed limits of the oil and gas location, access roads, or pipeline corridors. Topsoil will be stripped from the site and segregated from subsoil for reuse during pad reclamation. Fugitive dust control measures will be implemented as described in the dust control section of this document. |
| Emissions mitigation | Form: (02A )
401991715
1/24/2020 | Dual fuel generators will be utilized during drilling operations to minimize air emission associated with the use of diesel fuel. Green completion practices will be employed to reduce emissions of gas and condensate vapor utilizing separators, tanks, sand traps, and other facilities to minimize emissions. |
| Drilling/Completion Operations | Form: (02A )
401991715
1/24/2020 | Closed loop drilling system will be utilized during drilling of all wells at this location. TEP will utilized remote centralized hydraulic fracturing operations during well completion operations minimizing un-necessary traffic and activities at the pad location. TEP will ensure 110 percent secondary containment for any volume of fluids contained at the well site during drilling and completions operations. |
| Interim Reclamation | Form: (02A )
401991715
1/24/2020 | Onsite production facilities will be minimized on the oil and gas location by transporting fluids off-site via pipelines and managing fluids at existing facilities. One (1) four-inch (4”) water pipeline will be installed from the pad to the Starkey Production Pit to minimize operational activities on the GR 12-29 pad. Additionally, three (3) two-inch (2”) condensate pipelines will be installed from the GR 12-29 pad to the GM Chevron Tank Facility to further minimize operational activities on the GR 12-29 pad and centrally locate similar operations in one location. This will also reduce vehicle traffic to the location, and minimize the overall disturbance footprint at the GR 12-29 pad. Additionally, remote telemetry equipment will be installed on location to minimize site visitation and truck traffic.
Exclusionary devices will be installed to prevent bird and other wildlife from accessing equipment stacks, vents, and openings. Certified weed-free native seed in seed mixes, except for non-native plants that benefit wildlife will be used. TEP will use certified, weed free grass hay, straw, hay or other mulch materials used for the reseeding and reclamation of disturbed areas. Soil amendments may be added to topsoil during reclamation actives to promote vegetation growth. |
