1/23/2012 | Communication plan for the Pratt 29H location:
a. Encana will hold a Community Meeting with the Vista Ridge neighborhood at least 45 days prior to re-entering the Pratt 29H location. The meeting will focus on addressing questions and concerns about all operations at the Pratt site.
b. Encana will follow the notification protocol that includes notifying all neighbors within a half mile of the Pratt location via a mailed notice that outlines the phases of activity and critical contact information. This mailed ‘Courtesy Notice’ will be sent 30 days before drilling starts on location. Addresses are to be pulled from the Weld County Assessors website.
c. Additional proactive communication to neighbors that Encana will do includes a phone call, email or text (neighbors can choose how to be contacted via Encana.com) within a half mile of the Pratt location, one week before starting construction, drilling and completions activity.
d. Encana will utilize the Town of Erie’s website and the Encana page to post the same notices that are sent to neighbors. The Encana activity map will be updated 30 days prior to activity starting on location. Erie’s LGD will also receive all notices and distribute via the Town’s communication system.
e. Encana can be reached with concerns and questions via their hotline 866-896-6371; email address communityrelationsUSA@encana.com; and their Encana Community Relations - Erie, Colorado Facebook Page. Encana will respond to most questions left at these channels within 24 hours. |

1/23/2012 | Noise: Will perform a baseline noise survey prior to any operational activity measuring the dBA at a distance of three hundred and fifty 350 feet from the noise source or sound level will be measured at a point twenty-five (25) feet from the structure towards the noise source. In situations where measurement of noise levels at 350 feet is impractical or unrepresentative due to topography, the measurement may be taken at a lesser distance and extrapolated to the 350-foot equivalent using the formula stated in Rule 802.
At a minimum Encana will:
a. Install 32’ temporary sound walls around the drill pad to minimize noise and light impacts during drilling and completions.
b. Install 16’ temporary sound wall along the south side of the access road.
c. Additional noise surveys will be completed during major change of operations and shared with COGCC inspectors when requested.
d. May place additional noise mitigation at operators discretion after review of noise surveys to ensure sound regulations are being met. |

10/4/2013 | Maximize equipment and wellhead setbacks from occupied buildings and residences to the extent feasible and practicable, as determined by Encana.
Prior to commencement of any new drilling or completion operations, provide notification to landowners within one-half (1/2) mile of the well-site.
Prior to commencement of any new drilling or completion operations, provide to an Erie designated staff member the following for the well-site for informational purposes only, which Encana may revise from time to time during operations:
a) A summary of planned operations, including identified access points and operational timeline, for posting to a local community information web-page
b) A site plan for site preparation, mobilization and demobilization
c) A plan for interim reclamation and vegetation of the site and final reclamation of the site
d) A plan for noise, light and dust mitigation, to the extent feasible
e) A traffic management plan
f) Updates of this information if any change during operations |

Utilize a high-low pressure vessel (HLP) and vapor recovery unit (VRU) for new wells drilled. Encana may remove the VRU system at such time Encana determines that the VRU system is no longer necessary due to reduced emission recoveries and/or efficiencies, but no earlier than one (1) year after the new well is drilled |
