PROPOSED PROJECT:
Gasco proposes to drill proposed well Quarter-Quarter42, Section 7, Township 11 South,and Range 17 East, in Duchesne County, Utah. The proposed well is locatedapproximately 25 miles southwest of Myton, Utah on Federally owned land managed byBureau of Land Management (BLM). Mineral extraction activities, transportationcorridors, agricultural and ranching activities, livestock grazing, and erosion havehistorically impacted the project area.
PROJECT AREA DESCRIPTION:
The proposed project area is underlain by sedimentary deposits of the Uinta Formation ofLate Middle Eocene age at an elevation of approximately 6,000 feet. Soils in the projectarea are sandy with overlaying surface rock. The project area contains variable slopesdominated by perennial shrubs. Additionally, there were rock outcrops scatteredthroughout the proposed location. Slopes within the project area boundaries range from0-5%.
The vegetation in the project area is alkaline shrub community consisting of shadscale,budsage, greasewood, and prickly pear. Halogeton and cheatgrass can be found in smallamounts within the native vegetation. For a complete list of common plants associatedwith the desert shrub community in the project area see Appendix A.
SURVEY METHODOLOGY:
In May 2007 the Utah Department of Wildlife Resources website{http://dwredc.nr.utah.gov/uedc/)was reviewed for Uintah County. This site contains theU.S. Fish and Wildlife Service list of threatened, endangered and candidate species aswell as the BLM/Utah State sensitive species list. In addition, past survey reports andenvironmental documents were reviewed to determine which federally listed threatened,endangered and candidate species, and which BLM/Utah sensitive species (collectivelyreferred to as special status species) have the potential to occur in the project area. For
complete list of special status plant species within the county of the project area see
Appendix B.
Data on existing soils, geology, elevations, and vegetation types within the proposedproject area were used to determine which of these species have potential to occur within
the project area. In-house Geographic Information System (GIS) layers were examined
for known locations of and suitable habitat for special status plant species within theproject area. From this pre-project assessment, it was determined that Sclerocactuswetlandicus has a low potential to occur within the proposed project area.
In addition to the above existing data research, a site-specific survey of the proposed well
location, access road, and pipeline was conducted on the above mentioned date.
SURVEY RESULTS:There was approximately 5 percent potential S. wetlandicus habitat identified in theproposed project area. No S. wetlandicus individuals were located.

GEOLOGY/TOPOGRAPHY: Rock exposures in the area are of the lower part of the lowermember (bottom) of the Uinta Formation, Upper Eocene age. There is an existing two track roadthrough the well pad. The pipeline follows along side the road. Most of the area along theroad/pipeline and the well pad has a thin cover of slope wash, sand, silt, and rock fragments. Thepad is on a flat bench with the same cover.

No recommendations are made for this well location, road or pipeline.
There is always some potential for discovery of significant paleontological resources in the UintaFormation. If significant vertebrate fossils (mammals, crocodiles, complete turtle shells, etc.) areencountered during construction, work should stop in that area and a paleontologist contacted toevaluate the material discovered.

4. State approval of this well does not supersede the required federal approval, which must beobtained prior to drilling.
5. This proposed well is located in an area for which drilling units (well spacing patterns) havenot been established through an order of the Board of Oil, Gas and Mining (the "Board").In order to avoid the possibility of waste or injury to correlative rights, the operator isrequested, once the well has been drilled, completed, and has produced, to analyzegeological and engineering data generated therefrom, as well as any similar data fromsurrounding areas if available. As soon as is practicable after completion of its analysis,and if the analysis suggests an area larger than the quarter-quarter section upon which thewell is located is being drained, the operator is requested to seek an appropriate orderfrom the Board establishing drilling and spacing units in conformance with such analysis
