HRES is an asset holding company operated by Encana. Encana personnel will operate and maintain the existing CDP facility. Some documents submitted with this application may reference Encana policies and procedures where applicable. The Wolf Ranch Compressor Station (facility) is proposed to be located in the NW 1/4 of section 24, Township 4 South, Range 96 West. It will be a grass roots facility that will boost medium pressure gas to high pressure for distribution to sales. The proposed unmanned facility is located approximately 25 miles north-northeast of Parachute, Colorado situated on Encana's North Parachute Ranch property. Natural gas will be compressed at the well pads and then transported to the proposed facility via pipeline. The gas will then enter the slug catcher where all the liquids will be separated. The gas then will flow to the compressors, which boost the gas to a higher pressure. From there, the gas goes on to sales. The free liquid then flows through a 3 phase gathering line to a central delivery point and then on to the main processing facility through existing pipelines. An amine plant, which removes CO2 from natural gas, is proposed to the north of the compressors in an open area, which also is proposed to be used as a storage/Iaydown yard. The Facility will consist of the following equipment: 3 Compressors - 2 Future Dehydrators 2 Generators - 1 Future Combustor 1 Slug Catcher - 3 Future Compressors 3 Filter Separators - 3 Future Filter Separators 1 Instrument Air Skid - 1 Future Amine Plant 1 Pig Receiver 2 Pig Launchers 1 BTEX Condenser 1 LACT 1 Storage/Maintenance Building 760 Horizon Dr. Suite 102 TEL 970.263.7800 Grand Junction, CO 81506 FAX 970.263.7456 www.oaconsulting.com Impact Analysis Hunter Ridge Energy Services LLC Wolf Ranch Compressor Station OLSSON ASSOCIATES OA Project No. 013-1093 760 Horizon Drive, Suite 102 1 Grand Junction, CO 81506 1 TEL 970.263.7800 1 FAX 970.263.7456 (YOLSSON ASSOCIATES ARTICLE 4 — IMPACT ANALYSIS HUNTER RIDGE ENERGY SERVICES, LLC WOLF RANCH COMPRESSOR STATION SECTION 4-203.G. IMPACT ANALYSIS 1. Adjacent Property Adjacent property owners are provided under a separate section of this application. 2. Adjacent Land Use Land uses adjacent to the project site are predominately natural gas operations and seasonal cattle grazing. The project site is located within a 15,800 acre parcel. Land uses on adjacent properties also include natural gas and agricultural operations. 3. Site Features The project is approximately 21 road miles north of Parachute, Colorado (17 linear air miles) on the Roan Plateau. The site is located in the Northwest 1/4 of Section 24, Township 4 South, Range 96 West of the 6th Principal Meridian, in Garfield County, Colorado. Primary access to the site is from County Road 215 and a series of private roads. The proposed project is on land owned by Encana Oil and Gas (USA) Inc. (Parcel No. 191727400012). The 15.98 acre project area is located on a ridge at approximately 8,140 feet in elevation. The site is located between two minor drainages. Native vegetation surrounding the site is consistent with sagebrush communities, mountain shrub, and aspen woodlands found throughout the region. 4. Soil Characteristics According to information prepared by the Natural Resources Conservation Service (NRCS) Soil Survey, soils in the area of this site have been mapped as the Parachute - Rhone loam (53) and Rhone loam (61). A copy of a NCRS Custom Soil Resource Report and a Geologic and Soils Hazards Report for the project site has been included with this application. The majority of the surface soil consists of the Parachute -Rhone loam (53) soils which are developed on 5 to 30 percent slopes, and consist of well drained soils on mountainsides and ridges, at elevations of 7,600 to 8,600 feet. The parent material of this soil is residuum weathered from sandstone. Depth to restrictive paralithic bedrock is 760 Horizon Drive, Suite 102 TEL 970.263.7800 Grand Junction, CO 81506 FAX 970.263.7456 www.olssonassociates.com Hunter Ridge Energy Services, LLC Wolf Ranch Compressor Station approximately 20 to 40 inches. This soil has a moderate corrosion of steel characteristics and low corrosion of concrete characteristics. A smaller portion of the site has surface soil consisting of Rhone loam (61) which have 30 to 70 percent slopes, and well drained soils on mountaintops and flanks, at elevations of 7,600 to 8,600 feet. The parent material of this soil is residuum weathered from sandstone. Depth to restrictive paralithic bedrock is approximately 40 to 60 inches. This soil has a moderate corrosion of steel characteristics and low corrosion of concrete characteristics. 5. Geology and Hazard A Geologic and Soil Hazard Report is included as part of this application under a separate tab. According to this report the overall geologic and soil hazards appear to be low. With proper engineering, the proposed location should be safe for construction and operation of the proposed Compressor Station. Stormwater controls and Best Management Practices (BMPs) should take into consideration the geology and soil types present at this location. These engineering controls and practices should be used temporarily and permanently to divert stormwater away from the construction areas and to prevent additional weight which could trigger landslide. Catchment basins should be sited and designed so as not to add weight to potentially unstable areas. 6. Groundwater and Aquifer Recharge Areas The proposed project site is not located in any mapped floodplain. An individual septic disposal system (ISDS) will not be used at this site so soils will not have to support waste disposal. The site will be graded so all on-site stormwater is directed to a stormwater settling basin before being released from the site. BMPs will be implemented to control stormwater run-off and soil erosion. Impacts to groundwater and aquifer recharge areas are not anticipated. 7. Environmental Impacts Hunter Ridge Energy Services (HRES) commissioned WestWater Engineering (WWE) to perform a biological survey of the project site and prepare a report addressing environmental impacts. This report is included as part of the LIR application and is incorporated in part into this narrative. a. Determination of long-term and short-term effects on flora and fauna FLORA Approximately 14.04 acres of native vegetation would be removed for construction. No Threaten and Endangered Species (TESS) plants would be affected. The landowner (Encana) has adopted an internal weed management program and implementation of the plan would reduce the effects of disturbance to the project site. Impact Analysis Page 2 • • Hunter Ridge Energy Services, LLC Wolf Ranch Compressor Station FAUNA Greater Sage -Grouse Approximately 14.04 acres of sagebrush habitat would be removed by the project. This sagebrush removal would take place within occupied habitat and a mapped sage -grouse production area. An increase in edge habitat could result in additional predation on sage -grouse. An increase in vehicle traffic could result in mortality due to collisions (road -kill), although the project would minimally contribute to a cumulative impact, given current traffic volumes on the Sprague Gulch Road. Raptors No raptor nesting habitat is directly affected. There is a possibility for long or short-term effects related to the increased human presence and activity associated with operation and maintenance of a compressor station site. American Elk and Mule Deer The construction of a compressor station will reduce available habitat for foraging, escape, and thermal cover by approximately 14.04 acres. Human presence and activity may affect animal distribution. No migration corridors will be affected. Deer and elk in this area have become somewhat habituated to human activity and any additional indirect impacts from construction of this project would be unlikely. An increase in vehicle traffic could result in mortality due to collisions (road -kill), although the project would minimally contribute to a cumulative impact, given current traffic volumes on the Sprague Gulch Road. Black Bear and Mountain Lion A small amount of serviceberry and Gambel oak has been affected by the existence of the compressor station site, minimally reducing the amount of available forage for black bears. Human presence and activity may affect animal distribution. Potential encounters of black bear with construction personnel could occur if garbage or food is available to resident bears and incidences of human -black bear interactions sometimes result in the euthanasia of offending bears by the Colorado Parks and Wildlife (CPW). An increase in vehicle traffic could result in mortality due to collisions (road -kill), although the project would minimally contribute to a cumulative impact, given current traffic volumes on the Sprague Gulch Road. Small Mammals, Birds (BCC), and Reptiles Habitat loss to these species would be approximately 14.04 acres. Human presence and activity may affect animal distribution. An increase in vehicle traffic could result in mortality due to collisions (road -kill), although the project would minimally contribute to a cumulative impact, given current traffic volumes on the Sprague Gulch Road. Impact Analysis Page 3 Hunter Ridge Energy Services, LLC Wolf Ranch Compressor Station Nesting habitat for migratory bird species, including BCC species, would be directly affected by the project. Construction activities have the potential to interfere with nesting birds if conducted during nesting season. b. Determination of the effect on significant archaeological, cultural, paleontological, and historic resources HRES commissioned Flattops Archeological Consultants to prepare a Class I Cultural Resource Study of the proposed site. This inventory found that no historical properties will be affected by this project. c. Determination of the effect on designated environmental resources, including critical Wildlife Habitat The development of the project is not expected to significantly affect any critical wildlife habitat for any wildlife species. Potential issues are outlined below. • Creation of hazardous conditions: Some passerine bird species may choose to nest in or on equipment or objects on the site, though inherent risks associated with these structures is low. By closing or covering all ports, hatches, cavities, and openings (such as the ends of pipes), this potential is decreased. Most non - game bird species and their nests are protected under the Migratory Bird Treaty Act (16 U.S.C. 703-712; Ch. 128; July 13, 1918; 40 Stat. 755) and damaging occupied nests could be considered a "take" resulting in a violation. • Indirect Construction Effects: Additional human presence and activity related to construction, operation, and maintenance of the compressor may influence spatial and temporal use of habitat surrounding the project by wildlife. Since the site exists amid significant human presence related to other activities in the area, the additional disturbance from this project is expected to be low, but does contribute to the cumulative effect of development in the area. ■ Alteration of Existing Vegetation: There would be approximately 14.04 acres of native vegetation removal related to this project. • Big Game Production Areas, Winter Range, and Migration Corridors: The project is located within an elk production area and near deer and elk winter ranges. No specific deer or elk migration corridors are affected. In the project area, the migration patterns are not confined to any specific route. Elk and deer migrate through this area, although there is no restrictive feature confining animals to this route, and this project would not create such a feature. • Road -kill: Speed limits are 25 miles -per -hour or less on Encana's private property and most wildlife in the area have become habituated to vehicle traffic. The potential for road -kill for most species should be low, with the exception of small mammals, birds (including sage -grouse), and reptiles. ■ Bird Nesting Habitat: Bird nesting habitat will be lost within the footprint of the • project, including sage -grouse nesting and brood rearing habitat. • Impact Analysis Page 4 • Hunter Ridge Energy Services, LLC Wolf Ranch Compressor Station d. Impacts on wildlife and domestic animals through creation of hazardous attractions, alteration of existing native vegetation, blockade of migration routes, use patterns, or other disruptions These impacts are addressed above under section 4-203 G.7.c and the attached Wildlife and Vegetative Impact Analysis prepared by WWE. e. Evaluation of any potential radiation hazard that may have been identified by the State or County Health Departments The proposed site is not located on or near a Uranium Mine Tailings Radiation Control Act (UMTRCA) Site or other known radiation hazard site. Radon is a naturally occurring, odorless and colorless radioactive gas that is produced by the radioactive decay of radioactive minerals present in the soils and bedrock. According to the Colorado Department of Public Health and Environment (CDPHE), Colorado has a moderate to high radon potential. Since the site is a facility that does not have buildings or an area that is occupied throughout the work day, the potential presence of radon is not expected to represent a geologic hazard or a significant worker exposure issue. f. Spill prevention control and countermeasures plan, if applicable All hydrocarbon based liquid storage will be in accordance with the SPCC plan that will be developed and implemented within six months of the construction of the project. Secondary containment will be designed to accommodate the largest storage tank volume, with sufficient freeboard for precipitation. Secondary containment may include earthen berms, impervious liners and steel containment. 8. Nuisance Adjacent lands will not be impacted by the generation of vapor, dust, smoke, noise, glare or vibration. 9. Reclamation Plan A Reclamation Plan has been provided under a separate tab.

Portable toilets will be used, and wastes will be hauled to a licensed disposal facility. SECTION 7-106. ADEQUATE PUBLIC UTILITIES The facility will not require public utilities in order to operate. SECTION 7-107. ACCESS AND ROADWAYS A. Access to Public Right of Way The site will be accessed from CR 215 and an existing private roadway across land owned by Encana. B. Safe Access The private road system was designed and built by the property owner to provide exclusive access to the natural gas operations in the area and is not designed for public use. The roadway is constructed of gravel and native materials and is treated with a dust palliative as needed. The roadway is currently used by a variety of vehicles ranging from heavy haulers to pick-up trucks. The roadway is designed, constructed and maintained to support these uses. This roadway provides a safe access to the site for the applicant. C. Adequate Capacity The proposed facility will generate little traffic, and the current road system has adequate capacity to support the proposal. See Traffic Analysis included with this application for additional details. SECTION 7-108. NO SIGNIFICANT RISK FROM NATURAL HAZARDS A. Use of Land Subject to Natural Hazards The proposed site is located outside of the area mapped for slope, soils and surficial geology hazards on the Garfield County on-line GIS map resources. The site is in a moderate wildfire area according to the Garfield County on-line GIS map resources. The site is located in an area that has not been mapped by FEMA for flood plains. The proposed project is located on the apex of a ridgeline and receives little to no off-site water Standards Analysis Page 2 • • Hunter Ridge Energy Services, LLC Wolf Ranch Compressor Station flows. There is little risk of flooding at this location. There is little or no risk of avalanches, landslides, mudflows and rockfalls since the site is located on a ridgeline. The proposed use is not subject to significant natural hazard risks and will not exacerbate existing natural hazards. B. Platting of Land Subject to Natural Hazards This application is not proposing the platting of land. This standard is not applicable DIVISION 2. GENERAL RESOURCE PROTECTION STANDARDS FOR LAND USE CHANGE PERMITS SECTION 7-201. AGRICULTURAL LANDS A. No Adverse Affect to Agricultural Operations The applicant leases the parcel for seasonal cattle grazing on the property. The proposed use will not directly affect this operation. B. Domestic Animal Controls Dogs and other domestic animals will not be permitted on the property or allowed to interfere with livestock. C. Fences The site will not be fenced. The facility will not impact livestock operations. D. Roads No new roads will be constructed to access this facility and the existing road will be maintained. E. Irrigation Ditches The proposed use will not impact irrigation ditches. SECTION 7-202. WILDLIFE HABITAT AREAS A. Buffers HRES commissioned WestWater Engineering (WWE) to perform a biological survey of the project site and prepare a report addressing environmental impacts. This report is included as part of the LIR application and is incorporated in part into this narrative. WWE does not recommend the use of buffers to mitigate the impact on wildlife in the area. B. Locational Controls of Land Disturbance The project area is mapped mule deer and American elk overall range. The site is completely within a mapped elk production area and an elk winter concentration area. The site is approximately 215 meters south of mapped mule deer severe winter range, and is Standards Analysis Page 3 Hunter Ridge Energy Services, LLC Wolf Ranch Compressor Station 375 meters from a mapped mule deer winter concentration area. Both species utilize the area extensively throughout the year. The construction of a compressor station will reduce available habitat for foraging, escape, and thermal cover by approximately 14.04 acres. Human presence and activity may affect animal distribution. According to the WWE report, no migration corridors will be affected. Deer and elk in this area have become somewhat habituated to human activity and any additional indirect impacts from construction of this project would be unlikely. An increase in vehicle traffic could result in mortality due to collisions (road -kill), although the project would minimally contribute to a cumulative impact, given current traffic volumes. C. Preservation of Native Vegetation The application of the landowner's noxious weed management and revegetation plan will provide a basis for appropriate mitigation. Reducing the amount of vegetation removed to only the area needed for construction will help reduce the effect of the project on native vegetation and wildlife habitat. The best method to mitigate loss of wildlife habitat is to increase the availability of native forage in the form of grasses and shrubs. Revegetation with native species would provide the greatest benefit for wildlife. D. Habitat Compensation As stated above, the best method to mitigate habitat Toss is to reestablish native forage when the site is reclaimed and revegetated. E. Domestic Animal Controls Domestic animals will not be kept at this facility. SECTION 7-203. PROTECTION OF WETLANDS AND WATERBODIES A. Minimum Setback The proposed site will be more than 35 feet from the Typical and Ordinary High Water elevation of any waterbody. B. Structures Permitted in Setback There will not be any structures located in this setback area. C. Structures and Activity Prohibited in Buffer Zone There will not be any structures or activities located in the buffer zone. SECTION 7-204. WATER QUALITY FROM POLLUTANTS A. Compliance with State and Federal Regulations HRES will comply with all applicable state and federal water quality regulations. Implementation and adherence to HRES's Stormwater Management Plan (SWMP) BMPs, project specific BMPS included with the site plan documents and Spill Prevention Control Standards Analysis Page 4 • • Hunter Ridge Energy Services, LLC Wolf Ranch Compressor Station and Countermeasures Plan (SPCC) will assure that natural vegetation and waterways are protected. B. Storage Near Waterbodies Restricted There will be no storage of hazardous materials within 100 feet of any waterbody. C. Spill Prevention HRES will comply with their Spill Prevention Control and Countermeasures Plan (SPCC). If any spill occurs, it will be cleaned up immediately and disposed of properly. D. Machine Maintenance There will be no maintenance of vehicles or mobile machinery at this site. Any emergency maintenance will be conducted only until these types of equipment can be moved. E. Fuel Storage Areas Fuel will not be stored at this proposed site. F. Waste Storage Any temporary storage of waste will be placed within a secondary containment facility. SECTION 7-205.

The drainage plan incorporates the use of a settlement pond with an outlet structure. Stormwater will be directed to this pond prior to being released from the site. SECTION 7-206. DRAINAGE A. Site Design to Facilitate Positive Drainage This standard requires that lots be laid out to provide positive drainage. The proposal will not be creating lots. This standard is not applicable. B. Coordination with Area Storm Drainage Pattern The proposal will not be creating Tots. This standard is not applicable. SECTION 7-207. STORMWATER RUN-OFF HRES commissioned River City Consultants to develop a drainage plan and report. These documents are included as part of this application and were developed to comply with Garfield County Unified Land Use Resolution. A. Avoid Direct Discharge to Streams or Other Waterbodies The drainage plan incorporates the use of a settlement pond with an outlet structure. Stormwater will be directed to this pond prior to being released. Standards Analysis Page 5 Hunter Ridge Energy Services, LLC Wolf Ranch Compressor Station B. Minimize Directly -Connected Impervious Areas The site will have minimal impervious areas. Equipment and structures will be placed on foundations and pads. Only the roofs and pads will contribute to the total impervious area. The balance of the site will be covered by gravel and native soil. C. Detain and Treat Runoff The water quality from the site will be addressed by revegetation of disturbed areas, check dams in the ditches, sediment basins, outlet structures, level spreaders, and surface stabilization/hardening (e.g., gravel surfaces and rip -rap). The sediment ponds were not designed to provide detention or retention. However, by their nature the ponds will slow runoff and will retard the peak flow from the site. SECTION 7-208. AIR QUALITY This facility will not cause air quality to be reduced below acceptable levels established by the Colorado Department of Public Health and Environment (CDPHE) Air Pollution Control Division and will comply with appropriate Colorado air emissions permitting regulations as applicable.

Access to the proposed site will be through Hunter Ridge Energy Services and Encana's North Parachute Ranch gate at the north end of Garfield County Road 215 (Parachute Creek Road). Traffic from the gate will travel over private roads approximately 8 miles to the north to reach the site. No new or improved access onto a County or State roadway will be necessary or proposed. The site is approximately 17 miles northwest of the Town of Parachute. WRCS will be constructed, operated, and reclaimed in three phases. These phases include: • Facility Construction (10-11 months) • Operation (30 years) • Reclamation (45 days) EXISTING NETWORK • WRCS will be accessed from County Road 215 and an existing private roadway. According to the guidelines in the Colorado Department of Transportation (CDOT) • State Highway Access Code, this road is classified as a Rural Highway (R -B). CR 215 is a two lane asphalt roadway with gravel shoulders. The road has a posted speed limit of 35 mph. TRAFFIC VOLUMES Traffic volumes on CR 215 were provided by the County for the South Middle Fork Water Facility Auxiliary Lane Study. These counts were collected in April, 2007. Background traffic projections for the Year 2027 were obtained by applying a 4% annual increase to the traffic volumes on CR 215. These numbers were rounded to the nearest five vehicles. The Year 2027 Background traffic volumes are shown on Figure 4. The site -generated traffic, Figure 5, was added to the existing and background traffic projections to develop total traffic projections. These projections are shown in Figures 6 and 7. Heavy vehicles will only be utilized for construction, repairs, and reclamation. Light vehicles will visit the site routinely to insure the WRCS is operating safely. S:\PROJECTS\1311 Hunter Ridge Energy Services\006 - Wolf Ranch Compressor Station\Design\Traffic\1311-006 WRCS-Traffic Study.docx Page 2 of 4 TRIP GENERATION/DISTRIBUTION • Trip generation is generally determined using rates found in the ITE Trip Generation manual. Rates from this publication are applied to values related to the size of the proposed site to estimate the trips expected to enter and exit the site. However, the manual does not provide for facilities similar to this use. To estimate trips expected for WRCS, existing traffic at sites with similar uses was evaluated. The following table summarizes the expected average and maximum trips for each phase. • • Table 1: Trip Generation - Wolf Ranch Compressor Station Phase Average Trips/Day Maximum Trips/Day Percent Trucks Total Trips/Phase Phase Duration Construction - Site Preparation Phase 16 173 53% 2195 27 weeks Operation 1 1 0 % 7300 30 years* Reclamation 7 7 14 % 42-84 45 days *Note that the estimated lifespan of the site is expected to be approximately 30 years. AUXILIARY LANE ANALYSIS As defined in the Garfield County Road Inventory Report, CR 215's Functional Classification is Local, set by Colorado Department of Transportation (CDOT) and the Federal Highway Administration (FHWA). With this classification, auxiliary lanes are required for left turns greater than 10 vehicles per hour (vph) and right turns greater than 25 vph during the peak hour. Traffic to the proposed site will enter onto private roads directly from the end of CR215 without turning movements. Therefore, no auxiliary lanes are warranted as part of this project. S:\PROJECTS\1311 Hunter Ridge Energy Services\006 - Wolf Ranch Compressor Station\Design\Traffic\1311-006 WRCS-Traffic Study.docx Page 3 of 4 EXISTING PARCELS Current land uses on the surrounding parcels are primarily natural gas development with rural residential and agricultural use. The majority of existing traffic is related to natural gas development activities. An existing private, aggregate roadway known as County Road 401 will primarily serve the existing site. No new access to state highways or railroad crossings will be required. RECOMMENDATIONS and CONCLUSIONS Based on the expected trip generation rates and traffic movement discussed above, the increase in average daily traffic is not expected to be significant. The one trip per day during normal operation will likely coincide with trips already being generated and servicing multiple sites in the vicinity on the same day. Only during construction and reclamation will there be an increase in traffic as a result of this site. This will be intermittent and short term. The additional traffic from the WRCS will not have a significant impact on the existing low levels of traffic on CR215. No roadway improvements or turn lanes are anticipated to be required to support this project.

This report satisfies the requirements of the Garfield County Unified Land Use Resolution, Article IV Section 4-502E part 8b: A determination of the effect on significant archaeological, cultural, paleontological, historic resources. . The project is located within Section 24, Township 4 South, Range 96 West (6th Principal Meridian); cultural resource files for Section 24 were reviewed for this study. The proposed project area is situated south of Litchliter Gulch and west of the West Fork of Story Gulch at an elevation of approximately 8150 feet above sea level. It is approximately 21 miles north of Parachute, Colorado. Access to the project area will utilize existing roads. The file search was conducted on May 21, 2013, by reviewing the Colorado Office of Archaeology and Historic Preservation's COMPASS database. Three previous cultural resource inventory projects have taken place in Section 24, T4S, R96W (Table 1); no cultural resources have been recorded as a result of these projects. Thus, based on the results of this Class I inventory, Flattops Archaeological Consultants recommends a finding of no historic properties affected. However, should cultural resources be unearthed during ground -disturbing activities, a qualified archaeologist should be notified. If you have questions or concerns, please do not hesitate to contact me at your convenience.

The proposed compressor is located along the west side of the Sprague Gulch Road and is located entirely on privately owned lands in Section 24, Township 4 South, Range 96 West; Sixth Principal Meridian. The current primary uses of the land are natural gas development, rangeland, and wildlife habitat. 1.2 General Survey Information Pedestrian surveys of the project area, including a 30 -meter radius, were conducted on May 9, 2013, which is early in the growing season for noxious weeds in this region. Identification of plant species was aided by using pertinent published field guides (Whitson et al. 2001, CWMA 2007, Kershaw et al. 1998, Weber and Wittmann 2012). Noxious weed locations were recorded with the aid of handheld global positioning system (GPS) receivers using NAD83 map datum, with all coordinate locations based on the Universal Transverse Mercator (UTM) coordinate system in Zone 12. Mapped soil types, as published by the Natural Resources Conservation Service (NRCS), U.S. Department of Agriculture (USDA), were reviewed to determine the soil types and vegetation characteristics at the project site (NRCS 2013). 2.0 LANDSCAPE SETTING 2.1 Terrain The terrain surrounding the project consists primarily of gently northerly sloping ridge tops and the sometimes steep adjacent hillsides. Elevation in the project area is approximately 8,200 feet. 2.2 Vegetation Native vegetation in the project area is consistent with sagebrush communities, mountain shrub, and aspen woodlands found throughout the region. Common plant species observed near the site are included in Table 1. WestWater Engineering Page 1 of 8 May 2013 Table 1. Common plant species observed near the site.

These plants compete aggressively with native vegetation and tend to spread quickly because the environmental factors that normally control them are absent. Disturbed soils, altered native vegetation communities, and areas with increased soil moisture often create prime conditions for weed infestations. The primary vectors that spread noxious weeds include humans, animals, water, and wind. The Colorado Noxious Weed Act (State of Colorado 2005) requires local governing bodies to develop noxious weed management plans. Both the State of Colorado and Garfield County maintain a list of plants that are considered to be noxious weeds. The State of Colorado noxious weed list segregates noxious weed species based by priority for control: 1. List A species must be eradicated whenever detected. 2. List B species spread should be halted. 3. List C species are widespread and the State will assist local jurisdictions which choose to manage those weeds. The Garfield County Weed Advisory Board has compiled a list of 21 plants from the State list considered to be noxious weeds within the county (Appendix A). The Garfield County Weed Advisory Board has duties to: 1. Develop a noxious weed list; 2. Develop a weed management plan for designated noxious weeds; and, 3. Recommend to the Board of County Commissioners that identified landowners submit an integrated weed management plan for their properties (Garfield County 2002). 3.2 Observations Noxious weeds observed in the project area include Canada thistle (Cirsium arvense — State B List), cheatgrass (Bromus tectorum — State C List), common mullein (Verbascum thapsus — State C List), houndstongue (Cynoglossum officinale — State B List), and spotted knapweed (Centaurea maculosa — State B List) (Figure 1; Appendix B). Canada thistle, houndstongue, and spotted knapweed are listed by Garfield County. No other state listed weeds were observed. In areas where soil disturbances have created growing conditions that favor non-native vegetation, several unlisted nuisance weed species are present. These plants can negate revegetation efforts and cause financial losses due to decreased seeding success and associated costs. The presence of these plants creates increased competition for resources and can negatively affect desirable native plant species. Plants in this category observed or known to exist in the project area include kochia (Bassia scoparia), Russian thistle (Salsola spp.), and yellow sweet clover (Melilotus officinalis). WestWater Engineering Page 2 of 8 May 2013 • • • • 3.3 Integrated Weed Management Control of invasive species is a difficult task and requires intensive on-going control measures. Care must be taken to avoid negatively impacting desirable plant communities and inviting infestation by other pioneer invaders. Weed management is best achieved by employing varied methods over several growing seasons, including inventory (surveys), direct treatments, prevention through best management practices, monitoring of treatment efficacy, and subsequent detection efforts. Weed management is often limited to controlling existing infestations and prevention of further infestations, rather than eradication, but through effective weed management practices eradication can be possible. Assessment of the existence and extent of noxious weeds for an area is essential for the development of an integrated weed management plan. This report provides an initial assessment of the occurrence of noxious weeds for the project area. In order to continue effective management of noxious weeds, further inventory and analysis is necessary to 1) determine the effectiveness of the past treatment strategies; 2) modify the treatment plan, if necessary; and 3) detect new infestations early, which would result in more economical treatments. 3.4 Prevention of Noxious Weed Infestations Weed management is usually costly, and heavy infestations may exceed the economic threshold for practical treatment. Prevention is an especially valuable and economical strategy for noxious weed management. Several simple practices should be employed to prevent weed infestations. The following practices will prevent infestation and thereby reduce costs associated with noxious weed control: • Prior to delivery to the site, all equipment and vehicles, including maintenance vehicles, should be thoroughly cleaned of soils from previous sites which may be contaminated with noxious weeds. • If working in sites with weed -seed contaminated soil, equipment should be cleaned of potentially seed -bearing soils and vegetative debris at the infested area prior to moving to uncontaminated terrain. • Avoid driving vehicles through areas where weed infestations exist. 3.5 Treatment and Control of Noxious Weed Infestations The landowner (Encana) has adopted an internal weed management program that is in compliance with all state and federal laws (WestWater 2009). The treatment method and timing will be determined by Encana and Encana's contracted licensed pesticide applicators. The recommendations provided in this report will be considered when developing annual treatment plans. General control methods for the species detected in the project area are provided for reference in Table 2. Table 2. General noxious weed control methods for species in the project area.

Biological controls (insects) may be an alternative in some cases. * Type: A = annual; B = biennial; P = perennial; Bold = Garfield County List 3.6 Recommended Treatment Strategies The following treatment strategies are presented for reference. It is important to know whether the weed species being managed is an annual, biennial, or perennial to select strategies that effectively control and eliminate the target. Treatment strategies vary depending on plant type, which are summarized in Tables 3 and 4. Herbicides should not always be the first treatment of choice when other methods can be effectively employed. Table 3. Treatment Strategies for Annual and Biennial Noxious Weeds Target: Prevent Seed Production 1. Hand grub (pull), hoe, till, cultivate in rosette stage and before flowering or seed maturity. If seeds develop, cut and bag seed heads. 2. Cut roots with a spade just below soil level. 3. Treat with herbicide in rosette or bolting stage, before flowering. 4. Mow biennials after bolting stage but before seed set. Mowing annuals will not prevent flowering but can reduce total seed production. (Sirota 2004) Table 4. Treatment Strategies for Perennials Target: Deplete nutrient reserves in root system, prevent seed production 1. Allow plants to expend as much energy from root system as possible. Do not treat when first emerging in spring but allow growth to bud/bloom stage. If seeds develop cut and bag if possible. 2. Herbicide treatment at bud to bloom stage or in the fall (recommended after August 15 when natural precipitation is present). In the fall plants draw nutrients into the roots for winter storage. Herbicides will be drawn down to the roots more efficiently at this time due to translocation of nutrients to roots rather than leaves. If the weed patch has been present for a long period of time another season of seed production is not as important as getting the herbicide into the root system. Spraying in fall (after middle August) will kill the following year's shoots, which are being formed on the roots at this time. WestWater Engineering Page 4 of 8 May 2013 • • Table 4. Treatment Strategies for Perennials Target: Deplete nutrient reserves in root system, prevent seed production 3. Mowing usually is not recommended because the plants will flower anyway, rather, seed production should be reduced. Many studies have shown that mowing perennials and spraying the regrowth is not as effective as spraying without mowing. Effect of mowing is species dependent therefore it is imperative to know the species and its basic biology. Timing of application must be done when biologically appropriate, which is not necessarily convenient. 4. Tillage may or may not be effective. Most perennial roots can sprout from pieces only 0.5 inch —1.0 inch long. Clean machinery thoroughly before leaving the weed patch. 5. Hand pulling is generally not recommended for perennial species unless you know the plants are seedlings and not established plants. Hand pulling can be effective on small patches but is very labor intensive because it must be done repeatedly. (Sirota 2004) Some weeds, particularly annuals and biennials, can develop resistance to herbicides. The ability to quickly develop immunity to herbicides, especially when they are used incorrectly, makes it imperative to use the proper chemicals at the correct time in the specified concentration according to the product label. Excessive application, either in frequency or concentration, can result in top kill. Repeated excessive applications may result in resistant phenotypes. 3.7 Noxious Weed Management — Best Management Practices Construction: The following practices should be adopted for any construction project to reduce the costs of noxious weed control and aid in prevention efforts. The practices include: • Prior to delivery to the site, equipment should be cleaned of soils remaining from previous construction sites which may be contaminated with noxious weeds. • Equipment and material handling should be done on established sites to reduce the area and extent of soil compaction. • In all cases, temporary disturbance should be kept to an absolute minimum. • Top soil, where present, should be segregated from deeper soils and replaced as top soil on the final grade, a process known as live topsoil handling. • If stored longer than one growing season, topsoil stockpiles should be seeded with non-invasive sterile hybrid grasses. • Wetland vegetation, if encountered, should be live handled like sod, temporarily watered if necessary, and placed over excavated sub -soil relative to the position from which the wetland sod was removed. • Cut-off collars should be placed on all wetland and stream crossings to prevent back washing (seed vector) and to ensure that soil moisture conditions are not impacted after construction so that native plants can re-establish from the existing seed bank. • If working in weed infested sites, equipment should be cleaned of potentially seed -bearing soils and vegetative debris prior to moving to uncontaminated terrain. • After construction, disturbed areas outside the footprint of the development should be immediately reseeded with an appropriate seed mix. Herbicides: Many of the listed noxious weed species in Colorado can be controlled with commercially available herbicides. Annual and biennial weeds are best controlled at the pre -bud stage after germination WestWater Engineering Page 5 of 8 May 2013 or in the spring of the second year. Selective herbicides are recommended to minimize damage to desirable grass species. It is important that applicators adhere to concentrations specified on herbicide containers. Herbicides generally do not work better at higher concentrations. Herbicide failures are frequently related to high concentrations that result in top kill before the active ingredient can be transported to the roots through the nutrient translocation process. If directed on the herbicide label, herbicide applications should use a surfactant or other adjuvant. Grazing: In the event grazing is allowed in the project area, it should be deferred in reclaimed areas until revegetation of desirable species has been successfully established and seeded plants have had opportunity to reproduce. Monitoring: Areas where noxious weed infestations are identified and treated should be inspected over time to ensure that control methods are working to reduce and suppress the identified infestation. The sites should be monitored until the infestations are eliminated. These inspections can then be used to prioritize future weed control efforts. 3.8 Commercial Applicator Recommendations A certified commercial applicator is a good choice for herbicide control efforts. Restricted herbicides require a Colorado licensed applicator. An applicator has the full range of knowledge, skills, equipment, and experience desired when dealing with tough noxious weeds. 4.0 REVEGETATION — RECLAMATION The landowner (Encana) has adopted an internal revegetation and reclamation program for its North Parachute Ranch property (WestWater 2009). Recommendations provided in this report will be considered when developing annual treatment plans. Successful reclamation of the project area is dependent upon soil type and texture, slope gradient and aspect, proper weed control, available water, and revegetation with suitable plant species. Site-specific reclamation plans should be developed with a qualified reclamation contractor. Reclamation services using multiple seed bin range drills and specialized equipment is available and should be used for reclamation seeding projects. In areas with slope greater than three percent or where laminar flows from runoff could affect reseeding success, imprinting of the seed bed is recommended. Imprinting can be in the form of dozer tracks or furrows perpendicular to the direction of slope. When utilizing hydro -seeding followed by mulching, imprinting should be done prior to seeding unless the mulch is to be crimped into the soil surface. If broadcast seeding and harrowing, imprinting should be done as part of the harrowing. Furrowing can be done by several methods, the most simple of which is to drill seed perpendicular to the direction of slope in a prepared bed. Other simple imprinting methods include deep hand raking and harrowing, always perpendicular to the direction of slope. A potentially beneficial alternative method to enhance reclamation success, particularly where there is poor or destroyed topsoil, is the application of vesicular-arbuscular mycorrhizal fungi (AMF). These fungi, mostly of the genus Glomus, are symbiotic with about 80 percent of all vegetation. Endo- mycorrhizal fungi are associated mostly with grasses and forbs and could be helpful in reclamation. In symbiosis, the fungi can increase water and nutrient transfer capacity of the host root system (Barrow and McCaslin 1995). Over-the-counter commercial products are available, and the best products should contain more than one fungi species. Compacted soils respond well to fossilized humic substances and by-products called humates. These humates, including humic and fulvic acids and humin were formed from pre -historic plant and animal deposits and can benefit reclamation efforts on compacted soils when applied as directed.
