12/14/2018 | Multi-well Pads (Rule 604.c.(2)E.
GWOC strives to utilize multi-well pads wherever technically and economically
practicable to minimize potential impacts to neighbors and the environment. Multi-well
pads are not always feasible due to numerous possible issues including but not limited
to; landowner requirements, topographic constraints, well bore reaches, setback
requirements, etc. This pad will be constructed in such a manner that noise mitigation
may be installed and removed without disturbing the site or landscaping. The pad has
all weather access roads to allow for operator and emergency response. This pad has
been placed as far as possible from building units. |

12/14/2018 | Leak Detection Plan (Rule 604.c(2)F.
GWOC designs its new facilities to both avoid leaks or releases as well as to help
detect them in a time-efficient manner to minimize potential impacts. Tanks and all
visible pipelines and valves etc. are inspected informally on a daily basis by company
lease operators. In addition, GWOC also conducts formal annual SPCC inspections,
and formal site specific and random audits, by third-party consultants to inspect for
general site conditions as well as condition of tanks, pipelines, and containment
structures. In addition, our company lease operators and Production staff review
production records, including volumes and pressures, looking for irregularities that may
indicate a problem with a tank or pipeline. If an irregularity is detected that may
indicate a potential release the suspect tank and/or pipeline(s) are removed from
service, isolated, and either pressure tested or visibly inspected for indications of a
potential leak. |

| General Housekeeping | Form: (02A )
401292391
12/14/2018 | General housekeeping will consist of neat and orderly storage of materials and fluids.
Wastes will be temporarily stored in sealed containers and regularly collected and
disposed of at offsite, suitable facilities. If spills occur cleanup will be implemented
within 24-48 hours, as appropriate, to minimize any commingling of waste materials
with storm water runoff. Routine maintenance will be limited to fueling and lubrication
of equipment. Drip pans will be used during routine fueling and maintenance to
contain spills or leaks. Any waste product from maintenance will be containerized and
transported offsite for disposal or recycling. There will be no major equipment
overhauls conducted onsite. Equipment will be transported offsite for major overhauls.
Cleanup will consist of patrolling the roadways, access areas, and other work areas to
pick up trash, scrap debris, other discarded materials, and any contaminated soil.
These materials will be disposed of properly. |
| Storm Water/Erosion Control | Form: (02A )
401292391
12/14/2018 | Storm Water Management Plans (SWMP) are in place to address construction, drilling
and operations associated with Oil and Gas development throughout the state of
Colorado in accordance with Colorado Department of Public Health and Environment
(CDPHE). Storm water controls will be constructed around the perimeter of the site
prior to construction. Typically, GWOC utilizes a ditch and berm system of storm water
control at its sites. BMP’s used are determined just prior to construction by a thirdparty
storm water contractor and may vary according to the location. Storm water
controls will remain in place until the pad is stabilized or reaches final reclamation. |

area for dry bulk chemicals and miscellaneous fluids. The dry chemicals in the storage
area shall be adequately protected to prevent contact with precipitation, shall be
elevated above storm- or standing water, and shall provide sufficient containment for

12/14/2018 | BOPE for well servicing (Rule 604.c.(2)J
A BOPE with a minimum pressure rating of 3,000 psi will be utilized. At a minimum it
will consist of 2 ram preventers and 1 annular preventer. The blind rams will be
positioned below the pipe rams. A backup system of pressure control will be onsite
consisting of at a minimum 1,000 psi accumulator (backup pressure). Accumulator is
tested to 1,000 psi. Operator may use fixed sized pipe rams matching the tubular size.
The annular preventer will be pressure tested to 250 psi low and 2,000 psi high for 10
minutes each. The ram preventers will be tested to 250 psi low and 2,500 psi high for
10 minutes each. All remaining well control equipment will be tested to 250 psi low and
2,500 psi high for 10 minutes each. The pressure tests will be conducted when the
equipment is first installed and every 30 days thereafter. Pipe rams and blind rams will
be function tested before every well service operation. Annual BOP inspections and
pressure tests will be performed by the service company and will be charted & retained
for 1 year. Backup stabbing valves shall be used on operations that require reverse
circulation. Valves will be pressure tested before each well service operation in low
pressure and high pressure range. The GWOC onsite representative will be certified in
Well Control Operations by a Well-Cap certified training service. |

During the drilling and completions phase, Great Western plans to construct
sound/visual walls that will be placed along all edges of the pad. This will also assist to
block out any lighting from nearby occupied structures. This pad will be constructed in
such a manner that noise mitigation may be installed and removed without disturbing

Where possible, drilling rig and completion equipment engine exhaust will be directed
away from occupied buildings to assist in mitigating potential odors. Sealed tanks with
pressure relief valves and emissions controls will be utilized for the production phase.
Great Western will be using a synthetic oil based drilling fluid called D822. Based upon
