6/4/2015 | Encana utilizes 24” tall corrugated galvanized metal berm walls with a capacity in excess of 150% of the largest tank contained within the wall. In addition, Encana best practices mandates the use of impervious liners that extends under each storage tank and up the walls, permanently affixed to the top of the metal berm wall. Protrusions of piping that come through the liner include a fully sealed “boot” to prevent leakage. |

6/4/2015 | Encana will perform a baseline noise survey prior to any operational activity measuring dBA at a distance 350 feet from the noise source (unless there is an occupied structure closer than that – then measurement will be taken 25 feet from the structure). If low frequency noise is a concern, measurement of dBC will be taken 25 feet from the occupied structure towards the noise source. As necessary, based on the survey, Encana will install temporary sound walls to minimize noise and light impacts during drilling and completions and will install permanent noise mitigation at the facility location as necessary to meet all COGCC regulations. |

required by Colorado Air Quality Control Commission Regulation Number 7. This will include at least monthly Audible,
Visual and Olfactory (AVO) inspections of the components and tanks at our Production Facilities at most weekly or at least
monthly starting on January 1, 2015. In addition, Encana will perform infra-red camera inspections of these components and the storage tanks at most monthly or at least annually. |

6/4/2015 | Current Encana drilling operations into and through productive horizons are planned to keep a hydrostatic “over-balance” on the formation. Encana does not intentionally drill ahead with flares and in cases where we do have flares, they are intermittent and only kept for the amount of time it takes to raise our drilling fluid weight to be over-balanced again. In more extreme cases of Well Control Operations, it’s possible to encounter a prolonged flare. This is required in order to bring operations back to normal and ensure proper safety of the rig/rig crews involved during this operation. These flaring instances are rare, but do occur. Encana typically has a good understanding of the pore pressures and will plan accordingly in order to help mitigate potential light impacts to nearby residents. |

Encana will maintain written records verifying proper design, construction, and maintenance, and will make these records available for inspection by the Director. In addition, onsite inspections are conducted internally to insure guidelines are met. |
