BLM Seeks Public Comment on Moxa Arch 3-D Geophysical Project EA

The Kemmerer BLM Office is seeking public participation and comment on the Moxa Arch 3-D Geophysical Project Environmental Assessment (EA). Mowrey Seismic filed a Notice of Intent (NOI) to Conduct Geophysical Operations, on behalf of Eagle Geophysical, Inc. (Eagle Geophysical) and Seitel Data, with the Bureau of Land Management (BLM), Kemmerer Field Office on January 24, 2006.

The proposed project is located approximately 5 miles southeast of the town of Opal on the northwestern corner of the project and the project’s southeastern border is approximately 2 miles east of the town of Granger. The proposed project would encompass approximately 130 square miles, of which approximately 68 square miles is federally managed, about 8 square miles of state managed land, and approximately 65 square miles of privately owned land, within Townships 19 and 20 North, Ranges 112 and 113 West, 6th Principal Meridian. Those portions of the project occurring on state and private lands are not subject to BLM authorization and would be permitted separately by Wyoming Oil and Gas Conservation Commission.

Receiver lines are oriented in an east-west direction with source lines generally oriented north-south. Sources lines are approximately 10 miles in length and are spaced approximately at 1,540-foot intervals with receivers being spaced approximately every 220 feet. Source lines are spaced in intervals of approximately 1,760 feet with source points occurring approximately 220 feet apart.

The proponent will stage all office and support operations in Rock Springs. Equipment will be positioned by helicopter and personnel on foot that access the location via the nearest access point to the pre-positioned equipment. Landing zones will be positioned at established sites within the project area and will be utilized for operations. In addition, a variety of standard vehicles (i.e. trucks, vans, etc.), ATVs, and support equipment tractor trailers and fuel trucks would be utilized throughout this project.

Energy generation will be accomplished by using five articulating buggy mounted vibrators. Buggies are equipped with low pressure tires, which have a tire pressure of approximately 10 to 13 pounds per square inch. The initial survey of the project is anticipated to begin in mid April to mid May and recording is anticipated to occur from August 1 through October 21.

Relationship to Existing Plans and Documents

Resource Management Plan – The document that directs management of the BLM-administered lands within the analysis area is the June 1986 Resource Management Plan (RMP). The objective for management of geophysical exploration is to provide opportunity for exploration of mineral resources and collection of geophysical data, while protecting resource values.

The following issues and concerns have been identified by the BLM to date. It is not meant to be an all-inclusive list, but rather a starting point for public input and a means of identifying the resource disciplines needed to conduct the analysis.

· Raptor nesting habitat
· Greater sage-grouse habitat
· Big game winter ranges
· Steep slopes
· Riparian areas
· Cultural resources including Sublette Cutoffs of the Oregon-California Trail
· Native American religious sites
· Paleological rock outcrops
· Abandoned mines
· Residential areas
· Underground utilities and other facilities
· Stream crossings
· Weeds
· Hunting areas and other recreation
· Grazing
· Sensitive soils
· Sensitive plant species
· Steep slopes
· Threatened and Endangered Species

The public is encouraged to participate in the environmental analysis process to help identify the level of analysis needed, alternatives to the proposed action, other issues or concerns that should be analyzed, mitigation opportunities, and any other comments or ideas to help ensure the completeness of the analysis process.

Please submit your comments by May 15, 2006. Written comments should be mailed to:
