Enterprise Gas Processing, LLC Enterprise Well-Tie Yard Limited Impact Review Enterprise Gas Processing, LLC Enterprise Well-Tie Yard Limited Impact Review Submittal Item Tab 6 Land Suitability Analysis 4-502 (D) The Land Suitability Analysis includes the following information: 1. Public Access to site – There is no Public Access to the site. Authorized vehicles must enter off County Road 215 onto Garden Gulch road, which is privately owned and maintained. All traffic must sign in at a guard shack for clearance, upon entering and exiting Garden Gulch Road. 2. Access to adjoining Roadways – Garden Gulch Road is the only adjoining roadway to the proposed site. 3. Easements – There are two existing Easements. One located outside the southern fence line running East-West, and one located outside the eastern fence line running North-South. 4. Topography and Slope – The project area lies at the head of a draw on a relatively flat surface. Elevation at the site is approximately 8,300 feet. Rolling ridgetops, bisected by draws dominate the landscape view in the area. 5. Natural Features – The proposed site was previously used and abandoned as a laydown yard by IXP Inc. There are no significant natural features on-site or off-site. 6. Drainage Features – The project area is located in the Parachute-Rhone watershed, on a ridge between Circle Dot Gulch and Sheep Kill Gulch, where topography is generally flat. These gulches drain into the West Fork of the Parachute Creek. Flows then ultimately proceed to the Colorado River. There are no existing man-made drainages or impoundments. 7. Water – A potable water supply is not proposed on the property since the land use is for storage of construction operation and construction materials only and no habitated structures are proposed on site. 8. Floodplain – The Site is not located in a geographic region that is affected by a flood plain or flood fringe. 9. Soils –Three soil types are found in the project area and include the following: 1)Northwater-Adel complex is a well drained soil with 5 to 50% Slope, 2) Parachute-Irigul-Rhone association is a well drained soil with 25 to 50% Slope and 3) Parachute-Rhone loam is a well drained soil with 5 to 30% slope. 10. Hazards – Geological hazards in the Piceance Basin include seismicity, landslides and ground subsidence. Seismicity-There are no known faults in the area. It is very unlikely that the activity in the project area would be affected by seismicity. Landslides-No landslide deposits were identified in the vicinity of the proposed Project. Ground Subsidence-There is no documented ground subsidence in the project area. 11. Natural Habitats – Vegetation is dominated by a mixture of mountain big sagebrush, Gamble Oak, service berry, snowberry, and aspen. A variety of grasses and forbs are distributed throughout the understory in the project area. A few common species include various wheatgrass species, bluegrass, western yarrow, dandelion, and lupine. No TESS plants were observed at the laydown yard during the survey. The terrain and soils found at the project site did not appear to be suitable habitat for these species. No federally listed threatened, endangered or candidate wildlife species are known to occupy the laydown yard and, thus, none of these species will be affected as a result of the proposed project. No State-listed wildlife species were observed during the survey of the project area. Sage Grouse sign was not observed within 200 feet of the site. The nearest active Sage Grouse lek to the project area is the Garden Gulch Lek which is located approximately 1.8 miles east of the laydown yard. Several raptor species nest, reside, forage, or pass through the general area of the laydown yard. Aspen groves within the project area are of sufficient height and density for tree nesting raptors. There is one known raptor nest within 0.25 miles of the laydown yard, belonging to any unknown species. There is potential for Brewer’s Sparrows to nest and forage in the sagebrush shrublands near the project area. The site is located within mule deer and American elk overall ranges and mule deer and elk summer ranges. CDOW “NDIS” mapping shows the project area to be within overall range for mountain lion and black bear. Mountain lion could travel through and hunt in the project area year round. The project area is not mapped by CDOW as a potential mountain lion conflict area. Black bear are a common resident mammal on the Roan Plateau. No mountain lion or black bear sign were observed on the site. Black bear sign was observed in an aspen grove north of the site, however. Common small mammal species that may be present on the project site include coyote, bobcat, golden-mantled ground squirrel, northern pocket gopher, mountain cottontail, white-tailed jackrabbit and least chipmunk. The project area does not lie within overall range for Wild Turkey, although it is possible that Wild Turkeys could occur in the area. The project area’s nearby shrublands, understory grasses, and nearby aspen trees provide nesting and foraging habitats for various other migratory and non-migratory bird species, depending on the season of the year. Sagebrush lizard, short-horned lizard, Western terrestrial garter snake, and racer are reptiles potentially occurring in the project area. Due to lack of water resources in the area, no amphibian species that are known to occur in Garfield County are present at the site. No potential jurisdictional COE crossings were observed during the survey conducted by WestWater Engineering. 12. Resource Areas – Grand River Institute (GRI) conducted a Class I cultural resource inventory for the proposed laydown yard site. Findings show that no previously recorded sites are located within the project area, and that no further consideration of cultural resources is recommended for the proposed project.

Prepared for: Enterprise Gas Processing LLC Prepared by: WestWater Engineering 2516 Foresight Circle #1 Grand Junction, CO 81505 September 2009 INTRODUCTION WestWater Engineering at the request of Enterprise Gas Processing LLC (Enterprise), conducted a site survey to locate and identify noxious weeds that occur at the Enterprise well tie yard. The well tie yard is located in Section 2, Township 6 South, Range 97 West (Figure 1). The project site has been previously disturbed and is located near several developed oil and gas roads. This report provides site specific noxious weeds observed at the Enterprise well tie yard, recommended treatments and management strategies for weed species observed at the site can be found in the Piceance Basin Field Wide Integrated Noxious and Invasive Weed Management Plan for Enterprise (WestWater 2009). 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 includes three categories. List A species must be eradicated whenever detected (none were found). List B species include weeds whose spread should be halted (2 species found). List C species are widespread, but the State will assist local jurisdictions which choose to manage those weeds (1 species found). All observations were recorded using handheld Global Positioning System (GPS) receivers and locations were recorded as Universal Transverse Mercator (UTM) coordinates (Datum: NAD 83, Zone: 12). Photographs were taken of the project site and weed-infested areas found during the survey. LANDSCAPE SETTING The project area lies at the head of a draw on a relatively flat surface. Elevation at the site is approximately 8,300 feet. Rolling ridgetops, bisected by draws dominate the landscape view in the area. Vegetation in the area is dominated by a mixture of mountain big sagebrush (Artemisia tridentata var. vaseyana), Gambel oak (Quercus gambelii), serviceberry (Amelanchier alnifolia), snowberry (Symphoricarpos rotundifolius), and aspen (Populus tremuloides). Groves of aspen and prefer northern exposures where soil moisture and temperatures are suitable for these species. A variety of grasses and forbs are distributed throughout the understory in the lease area. A few common species include various wheatgrass species (Elymus spp. or Pascopyrum spp.), bluegrass (Poa spp.), western yarrow (Achillea lanulosa), dandelion (Taraxacum spp), and lupine (Lupinus spp). NOXIOUS WEEDS Colorado State listed noxious weeds found at the well tie yard site include: bull thistle (Cirsium vulgare), houndstongue (Cynoglossum officinale), and cheatgrass (Bromus tectorum). Other common annual weeds observed at the site include: prostrate knotweed (Polygonum aviculare), kochia (Kochia scoparia), Russian thistle (Salsola spp.), tumble mustard (Sisymbrium altissimum), lambsquarter (Chenopodium berlandieri), and pigweed (Amaranthus retroflexus).

Cary3 1GIS/CAD Specialist Bikis Water Consultants, LLC 555 RiverGate Lane, Suite B4-82 Durango, CO 81301 970-385-2340 [email protected] 2Associate Professor Department of Geosciences – Fort Lewis College 1000 Rim Drive Durango, CO 81301 970-247-7475 [email protected] 3Visiting Instructor Department of Geosciences – Fort Lewis College 1000 Rim Drive Durango, CO 81301 970-247-7620 [email protected] ABSTRACT The La Plata mining district is located in southwestern Colorado, and contains numerous gold, silver, and copper deposits. Geologic and structural data for the district was obtained from georeferencing and digitizing an historic geologic map. New stream sediment samples were collected at 41 locations throughout the area, and analyzed for metal concentrations. Using ArcGIS’s surface hydrologic modeling tools, individual watersheds were delineated upstream for each sediment sample location. A geodatabase has been created consisting of geologic formations and structures, veins, rock ages, historic mines, and geochemical anomalies associated with the 41 watersheds. The Spatial Analyst extension was used to analyze the data to aid in visualization and quantification of the relationships among geology, structure, and geochemistry. The results provide greater insight into regional geochemical domains of mineralization and in the modeling of spatial associations of known ore deposits within the mining district. 1 Introduction The objective of this project was to build a spatial database of structural, lithological, and geochemical data, so that a spatial model for gold exploration could be created. This model was created using the Fuzzy Logic Method developed by Graeme Bonham-Carter of the Geologic Survey of Canada, and Gary Reins of the USGS.

  • The Proposed Montezuma Forest Reserve Colorado
    THE PROPOSED MONTEZUMA FOREST RESERVE COLORADO ---- Examination, Report and Recommendations by Coert DuBois ---- Bureau of Forestry U. S. Department of Agriculture 1904 A facsimile of a copy acquired from the National Archives and Records Administration, Rocky Mountain Regional Office at Denver Federal Center December 2007 by David Bradford. 2 THE PROPOSED MONTEZUMA FOREST RESERVE, COLORADO ---- By Coert DuBois Forest Assistant, Forest Service ---- Location and Area The area included within the proposed Montezuma Forest Reserve lies in parts of San Miguel, Dolores, San Juan, La Plata, and Montezuma Counties in southwest Colorado, and includes the La Plata, Bear River, and San Miguel mountain ranges. The proposed boundaries include a total acreage of 570,260. Topography The mountains divide the area into three watersheds. On the north slope of the San Miguel Range are the headwaters of several small creeks which flow into the San Miguel River. The east slopes of the Bear River and La Plata Mountains are drained by Cascade, Hermosa, and Junction Creeks, all tributaries of the Animas River. The most important division is the drainage basin of the Mancos and Dolores Rivers, or the south and west slopes of the mountains. The heads of the Mancos River rise high up in the La Plata Mountains and consist of three forks fed by many smaller creeks, which join and form the main Mancos near the south boundary. A low mesa divides the waters of the Mancos from those of the Dolores. The Dolores River, the most important in the southwest part of the State, with the exception of the San Juan, has its sources in all three ranges, being fed by a great many mountain streams, the chief of which are the West Fork, Bear Creek, Beaver Creek, and Lost Canon Creek.

  • West Slope Mountain Lion Management Plan
    West Slope Mountain Lion Plan: Sept 2, 2020 Colorado Parks and Wildlife COLORADO WEST SLOPE MOUNTAIN LION (Puma concolor) MANAGEMENT PLAN Northwest and Southwest Regions September 2020 Colorado Parks and Wildlife Approved by the Parks and Wildlife Commission on September 2, 2020 1 West Slope Mountain Lion Plan: Sept 2, 2020 Executive Summary Colorado Parks and Wildlife’s (CPW) aim for mountain lion management on the West Slope of Colorado is to preserve, protect, enhance and manage mountain lions for the use, benefit, and enjoyment of the state’s citizens and visitors. CPW strives to ensure that mountain lions continue to exist in relatively stable numbers in western Colorado for current and future generations to enjoy through hunting, occasional observation, and for their scientific, ecological and aesthetic value. This mountain lion management plan provides the framework for how CPW will achieve this goal in the Northwest and Southwest CPW Administrative Regions and replaces all existing West Slope Data Analysis Unit (DAU) lion management plans. This West Slope Mountain Lion Management Plan operates with the assertion that CPW’s thirteen DAU plans in western Colorado, each written in 2004 to describe a single lion population, are too small in spatial scale to properly manage solitary, low-density, wide- ranging carnivores like mountain lions. In many cases, sample sizes of mountain lion mortality data have been too small to reduce uncertainty in management conclusions and have not effectively informed past DAU objectives. This plan increases the size of the management unit at which analysis and evaluation will occur to a more appropriate scale: the CPW Administrative Northwest and Southwest Regions.

Annual NMGS Fall Field Conference Guidebooks Every fall since 1950, the New Mexico Geological Society (NMGS) has held an annual Fall Field Conference that explores some region of New Mexico (or surrounding states). Always well attended, these conferences provide a guidebook to participants. Besides detailed road logs, the guidebooks contain many well written, edited, and peer-reviewed geoscience papers. These books have set the national standard for geologic guidebooks and are an essential geologic reference for anyone working in or around New Mexico. Free Downloads NMGS has decided to make peer-reviewed papers from our Fall Field Conference guidebooks available for free download. Non-members will have access to guidebook papers two years after publication. Members have access to all papers. This is in keeping with our mission of promoting interest, research, and cooperation regarding geology in New Mexico. However, guidebook sales represent a significant proportion of our operating budget. Therefore, only research papers are available for download. Road logs, mini-papers, maps, stratigraphic charts, and other selected content are available only in the printed guidebooks.
