4/28/2020 | Prior to submittal, TEP conducted onsites and meetings with the Bureau of Land Management (BLM), Colorado Parks and Wildlife, and the associated private landowners. These onsites and meetings were held to discuss TEP’s proposed activities on the RWF 311-15 pad. Changes were made to the proposed development plan based on feedback received from all stakeholders and included in this sundry.
The RWF 311-15 pad was evaluated as a remote frac location to support completion operations for the ten (10) proposed wells on the Federal RWF 12-9 pad (COGCC Loc ID 335636). This location was chosen due to several factors including (1) its proximity to existing TEP operated facilities and existing pipeline infrastructure, (2) the location could be reconstructed to support temporary frac equipment, and (3) maximizes the utility of existing disturbance associated with previous oil and gas operations minimizing surface impacts to the greatest extent possible. |
| Pre-Construction | Form: (04 )
402350940
4/28/2020 | 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 pre-construction meeting. Staking will identify the boundaries of the proposed site to protect existing vegetation in areas that should not be disturbed. |

4/28/2020 | Storage of material and fluids on location during 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 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 completions operations. |
| Wildlife | Form: (04 )
402350940
4/28/2020 | The RWF 311-15 pad is located within Mule Deer Critical Winter Range sensitive wildlife habitat as currently mapped per COGCC geospatial data. The access road to the RWF 311-15 pad also traverses through Mule Deer Critical Winter Range sensitive wildlife habitat as currently mapped per COGCC geospatial data. TEP does not anticipate construction activities to occur during winter months (Dec. 1 - April 30.). However, completions operations may occur during this timeframe. TEP will consult with BLM and CPW to determine appropriate compensatory mitigation to offset impacts to wildlife if construction, drilling, or completions operations are planned to occur during winter months.
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 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. Exclusionary devices will be installed to prevent bird and other wildlife from accessing equipment stacks, vents, and openings.
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. 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. Please see the attached CPW correspondence for additional details. |
| Storm Water/Erosion Control | Form: (04 )
402350940
4/28/2020 | 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 COR404624). See the construction layout for the planned stormwater BMP’s proposed for installation at the site for further details. |
| Dust control | Form: (04 )
402350940
4/28/2020 | 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 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. |
| Construction | Form: (04 )
402350940
4/28/2020 | 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: (04 )
402350940
4/28/2020 | 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. All well fluids and gas will be directed to high pressure four phase separators. All produced water will be directed to a low-pressure separator to flash any remaining hydrocarbon. All unsaleable quantities of hydrocarbon will be sent to flare and water will be sent to sealed water tanks. The sealed water tanks will be emission controlled and manifolded to a combustion unit to incinerate any remaining odor causing vapors. All water flowing into the sealed water tanks will be pumped offsite to one of TEP’s produced water management facilities. |
| Drilling/Completion Operations | Form: (04 )
402350940
4/28/2020 | TEP will utilized the RWF 311-15 pad as a frac pad for centralized hydraulic fracturing operations during well completion operations for the proposed wells on the RWF 12-9 pad, minimizing unnecessary traffic. 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: (04 )
402350940
4/28/2020 | 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. |
