Standards Page 1 Article VII, § 7-106 Adequate Central Water Distribution and Wastewater Safe operation of the Encana SMF facility will require the installation of a control building which will house equipment related to data monitoring and data collection. Encana will provide an adequate potable water supply and address wastewater storage to serve the proposed use of the control room facility. Both the potable water supplies and the wastewater controls will be provided by a licensed supplier of these services. Water and waste (sewage) from the facility will be handled via a vault and haul system designed to accommodate a single person and will meet all appropriate CDPHE requirements. A licensed water and sewage hauler will monitor the system approximately every seven days. The system will also be permitted according to Garfield County Building Department requirements. Article VII, § 7-107 Adequate Public Utilities Supply As required, electricity will be supplied on-site by either a new utility connect to Xcel Energy (via an existing line) or by diesel or natural gas generator(s). Encana has had discussions with Excel officials and it has been determined that the local distribution power line has adequate capacity for the electrical loads expected. If generators are used on site, they will comply with appropriate Colorado air emissions permitting regulation as applicable. Any fuel storage tanks located on-site for operation of the generator(s) will be included in the area wide Spill Prevention Control and Countermeasures (SPCC) plan. No additional public utilities will be utilized. Article VII, § 7-108 Access and Roadways The proposed facility will not adversely impact adjoining roadways due to the anticipated low operational traffic volumes. There is an existing access to this site that is located north of the Wheeler Gulch Road intersection. This access will be eliminated when the new access is constructed and the Water Facility is completed. The new access will be designed to Garfield County standards (Section 7-307) for grading, width and surface. Text describing the proposed access is also provided as part of the Project Narrative accompanying this submittal. Additional details are shown on Page C1 (Site Plan), Page C2 (County Road 215 Plan and Profile) and Page C3 (County Road 215 Striping and Signing Plan) of the complete site plan set submitted with this application. As detailed in the Auxiliary Lane Analysis, prepared by River City Consultants, access is proposed via a new access to County Road 215. This access will be the fourth leg of the County Road 215/Wheeler Gulch Road intersection. The Auxiliary Turn Lane Assessment addressed the sight distance, trip generation, directional distribution, site -assignment of trips, and recommendations for auxiliary turn lanes associated with the proposed Encana Oil & Gas South Middle Fork Water Facility near Parachute, Colorado. Based on the CDOT Access Code, the projected trip generation and directional distribution, a northbound left -turn deceleration lane is not warranted based on the revised use and trip generation but will be provided due to truck traffic. A copy of this report is included in the supplemental materials section. Standards Page 2 Article VII, § 7-109 No Significant Risk from Natural Hazards The proposed project site is located on the relatively level valley floor on the eastern edge of the Piceance Basin, at an elevation of approximately 5,577 feet approximately three miles north of the Town of Parachute. No geologic, slope, and soil hazards have been mapped by Garfield County in this area and no faults or other hazards are evident on the Geologic Map of Colorado. General Resource Protection Standards for Land Use Change Permits: Article VII, § 7-201 Protection of Agricultural Lands A. No Adverse Effect to Agricultural Operations The proposed facility will not adversely impact agricultural operations that are conducted on the subject property or adjacent lands. B.

Irrigation Ditches Implementation of the engineered drainage plan and conformance with stormwater best management practices will assure irrigation ditches on and adjacent to the subject property will not be impacted by the facility. Article VII, § 7-202 Protection of Wildlife Habitat Areas The Wildlife and Vegetative Impact Analysis Report included with this submittal concluded that the facility will not create hazardous attractions to avian or mammalian wildlife species, vegetation, block migration routes, or cause a change in habitat use. No impacts to federally listed or locally significant plant or animals are anticipated. Noxious weeds will be removed as applicable on site. To mitigate impacts to the natural habitat associated with the proposed project Encana will adhere to the recommendations included in the Wildlife and Vegetative Impact Analysis Report. During the reclamation phase, the property will be re -seeded and re- graded to pre -disturbance levels. Article VII, § 7-203 Protection of Wetlands and Water bodies There are no wetlands or water bodies in the proximity of the water impoundment facility. Engineering controls and storm water Best Management Practices (BMP's) will be utilized to ensure the continued protection of water bodies from stormwater runoff during operation of the facility. Article VII, § 7-204 Protection of Water Quality from Pollutants The operator will operate the facility in order to maintain the required buffer between the disturbed area and the natural vegetation and waterways. Implementation and adherence to Encana's Storm Water Management Plan (SWMP) Best Management Practices (BMPs) and Spill Prevention Control and Countermeasures Plan (SPCC) will assure that natural vegetation and waterways are protected. BMPs utilized during construction and operation will include (but not be limited to) straw wattles, check dams, hay bales and silt fencing. According to the SPCC criteria, secondary containment will be comprised primarily of berms, impervious synthetic liners an steel containment structures. Article VII, § 7-205 Erosion and Sedimentation Encana's Area Wide Stormwater Management Plan is currently being renewed and expaned to include this facility. No construction will begin until such time as said plan is approved. BMPs will be utilized to ensure the continued protection of water bodies from storm water runoff during construction of the facility. Article VII, § 7-206 Drainage: A. Site Design to Facilitate Positive Drainage This standard requires that lots be laid out to provide positive drainage. Lots are not proposed as part of this land use application. Because of the small size of the proposed Standards Page 4 project area, the site will not create any impacts to existing drainage patterns. Additional details are provided in the Grading Plan (Page C4 of the site plan set) and Construction Erosion Control Plan (Pages C7 to C9 of the site plan set) accompanying this submittal. B. Coordination with Area Storm Drainage Pattern This standard also addresses individual lot drainage within a residential development and is not applicable to this use. The proposed facility will not impact natural drainage patterns. Article VII, § 7-207 Stormwater Run -Off The SWMP has been included with this application and covers all applicable activities associated with the facility's disturbance. The facility is not within 100 feet of a water body; however it will require greater than 10,000 feet of impervious surface. Drainage details shown on the site plan demonstrate that the proposed facility will not impact the natural drainage patterns. Additionally, the facility will be permitted according to the COGCC criteria for E&P waste facilities which require the facility be engineered with run-on and run-off controls to accommodate a 100 year, 24-hour storm water event.
