Drilling/Completion Operations | Form: (02 ) 400450055 9/19/2013 | Prior to drilling operations, Operator will perform an anti-collision scan of existing offset wells that have the potential of being within close proximity of the proposed well. This anti-collision scan will include definitive MWD or gyro surveys of the offset wells with included error of uncertainty per survey instrument, and compared against the proposed well path with its respective error of uncertainty. If current surveys do not exist for the offset wells, Operator may have gyro surveys conducted to verify bottomhole location. The proposed well will only be drilled if the anti-collision scan results indicate that there is not a risk for collision, or harm to people or the environment. For the proposed well, upon conclusion of drilling operations, an as-constructed gyro survey will be submitted to COGCC with the Form 5.

as specified by the then current requirements of the Code. |
General Housekeeping | Form: (02 ) 400868294 11/5/2015 | Road repairs.
(a) Erie and Encana recognize that truck traffic accessing the Identified Well Pads may
cause damage to Erie roads and that road repairs may be needed to mitigate such
damage. To this end, Encana will arrange for a qualified outside consultant to perform
a road impact study for all Erie roads that are used to access an Identified Well Pad
during the Term of this Agreement. The consultant will conduct the first part of the
study prior to Encana’s operations at such Well Pad and the second part of the study
after Encana completes all drilling and hydraulic fracturing at such Well Pad. Encana
and Erie will use these studies to determine the extent of any damage accruing to the
road during the study period. Encana will then promptly pay Erie to repair such
damage or else arrange and pay the cost of such repairs itself whichever Erie prefers.
(b) Encana shall maintain Financial Assurance to secure its road repair obligations
under this Agreement. The amount of such Financial Assurance shall equal Erie’s
annual road maintenance budget as of the Effective Date multiplied by the percentage
yielded by dividing the total number of Erie road miles as of the Effective Date into the
number of such road miles that Encana will use to access the Identified Well Pads.
Encana shall select the form of such Financial Assurance and shall maintain such
Assurance until Encana fulfills its obligation to repair road damage under Subsection
(a).

subject to the light industrial zone noise standard under COGCC Regulations 802.b
and 604.c.(2)(A) does not exceed sixty (60) db(A) and that the noise level from
operations subject to the industrial zone noise standard under COGCC Regulations
802.b and 604.c.(2)(A) is reduced at least five (5) db(A) below the maximum level
permitted by those Regulations. For this purpose, the noise level shall be measured
as set forth in COGCC Regulations 802.b & c, except no measurements shall be taken
when traffic is passing the sound level meter, Encana shall be present during all
measurements, and building units shall be limited to those units existing as of the
Effective Date. As set forth in COGCC Regulation 802.b, the noise levels shall be
subject to increase for a period not to exceed fifteen (15) minutes in any one (1) hour
period and reduction for periodic, impulsive or shrill noises.
(b) For db(C) scale noise, Encana shall comply with the requirements of COGCC
Regulation 802, as such requirements may be amended during the term of this

Emissions mitigation | Form: (02 ) 400868294 11/5/2015 | Well leak detection and repair
(a) To identify leaks, Encana will perform audio, visual and olfactory inspections on a
monthly basis at all of its new and existing wells and related facilities and equipment
within Erie’s Town Limits, provided that such related facilities and equipment are
located on the pads for such wells, are part of adjacent tanks used for such pad sites,
or are part of storage tanks for such pad sites authorized under Article IV, Section 4 of
the Operator Agreement. Encana will also inspect each such well with an infra-red
camera on a monthly basis. The initial baseline inspections will occur within sixty (60)
calendar days after the Effective Date. After a well has produced for twelve (12)
months, the frequency of such inspections shall decrease from monthly to quarterly. If
Encana determines that any repairs are required based on these inspections, Encana
will promptly initiate these repairs.
(b) Encana will report to Erie on the inspection results and any associated repairs the
month after the inspection or repair occurs. This information will be collectively
reported on a monthly basis in the same format that Encana uses for reporting to the
Air Pollution Control Division under Regulation 7, but that is specific to wells located
within the Erie Town Limits. Erie will make this information publicly available.
(c) This BMP will terminate five (5) years after the Effective Date, after which Encana
will continue to comply with the leak detection, repair, and reporting requirements of
Regulation 7, as such requirements may be amended. |
Emissions mitigation | Form: (02 ) 400868294 11/5/2015 | In an effort to reduce air emissions, Encana intends to construct a central gathering
and storage facility at a location in 1N-68W-Section 21 (the “Hub”) to receive liquids
from the wells which are the subject of this Agreement. As a result, Encana will not
install hydrocarbon storage tanks at these pad sites, which will eliminate potential
sources of hydrocarbons from the sites. However, Encana will still install at the pad
sites all other equipment and facilities necessary for the production of hydrocarbons,
including wellhead equipment, separation equipment, electrical equipment, and
temporary flowback equipment (including temporary storage tanks). In addition, this
BMP is subject to Article IV, Sections 3 and 4 of the Agreement. |
