12/5/2019 | 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 GR 14-28 pad. Changes were made to the proposed development plan based on feedback received from all stakeholders and included in this sundry.
The GR 14-28 pad was evaluated as a remote frac location to support completion operations for the sixteen (16) proposed wells on the Chevron GR 12-9 pad (COGCC Loc ID 335260) and the fourteen (14) proposed wells on the GM 12-20 pad (COGCC Loc ID 335426). 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 expanded to support temporary frac equipment without creating new disturbance, and (3) maximizes the utility of existing disturbance associated with previous Oil & Gas operations and minimizes surface impacts to the greatest extent possible. |
| Pre-Construction | Form: (04 )
402179706
12/5/2019 | 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. |
| General Housekeeping | Form: (04 )
402179706
12/5/2019 | 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 drilling and completions operations. |
| Wildlife | Form: (04 )
402179706
12/5/2019 | The GR 14-28 pad and the access road to the location is within Mule Deer Critical Winter Range and Elk Winter Concentration Area sensitive wildlife habitat boundaries per COGCC geospatial data. TEP does not anticipate construction activities to occur within during winter months (Dec. 1 – April 30.), however completions operations may occur during this time frame. TEP will consult with BLM and CPW to determine appropriate compensatory mitigation to off-set impacts to wildlife if activities (construction or completions) are planned to occur during winter months. The GR 14-28 pad is being proposed as a remote frac pad for the GR 12-29 and GM 12-20 pads to minimize activities and vehicle traffic minimizing impacts to wildlife. 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.
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.

| Storm Water/Erosion Control | Form: (04 )
402179706
12/5/2019 | 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). |
| Dust control | Form: (04 )
402179706
12/5/2019 | 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 )
402179706
12/5/2019 | 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 )
402179706
12/5/2019 | 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. To minimize odors during the flowback phase of well completion operations, all fluids will be sent through high pressure separation and low-pressure separation before being sent to sealed top flowback tanks. The sealed top flowback tank vents will be manifolded and piped to a combustion unit to incinerate all odor causing vapors. Emergency relief valves (ERV’s) on the sealed flowback tanks will be piped to an additional sealed tank. All water flowing into the sealed top flowback tank will be pumped off site to one of TEP’s produced water management facilities. |
| Drilling/Completion Operations | Form: (04 )
402179706
12/5/2019 | TEP will utilized the GR 14-28 pad as a frac pad for centralized hydraulic fracturing operations during well completion operations for the proposed wells on the GR 12-29 pad and GM 12-20 pad minimizing unnecessary 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.
To minimize light pollution during drilling and completions operations facility light will be directed downward toward the Oil & Gas Location wherever possible. Lighting directed way from the facility will be limited to those necessary to operate safely during nighttime operations. Lighting placement and direction will be evaluated during initial equipment setup to determine where adjustment can be made to minimize light pollution. Generally, lighting will be directed in a southerly direction, where possible, to minimize the lighting directed towards the building unit located approximately 1,500’ north of the pad. Light pollution is not expected to be problematic due to vegetative barriers (vegetation located along Parachute Creek) between the pad and the building unit. |

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. |
