BLM MISSION STATEMENT 

The Bureau of Land Management is responsible for the stewardship of our public lands. It is 

committed to manage, protect, and improve these lands in a manner to serve the needs of the 

American people for all times. 

Management is based upon the principles of multiple use and sustained yield of our nation's 

resources within a framework of environmental responsibility and scientific technology. These 

resources include recreation, rangelands, timber, minerals, watershed, fish and wildlife, 

wilderness, air and scenic, scientific, and cultural values.

Dear Reader: 

In accordance with the National Environmental Policy Act (NEPA) of 1969, this Environmental 

Assessment (EA) has been prepared for the Overland Pass Pipeline Piceance Basin Lateral Natural Gas 

Liquids Project as applied for by the Overland Pass Pipeline Company, LLC (OPPC). This EA analyzes 

impacts that would be expected from the Proposed Action and the No Action Alternative. The Bureau of 

Land Management (BLM) is the lead federal agency in the preparation of the Overland Pass Pipeline 

Piceance Basin Lateral Natural Gas Liquids Project EA. Approximately 48 percent of the total pipeline 

would be located on Federal lands administered by the BLM. 

The proposed 152-mile natural gas liquids (NGL) pipeline project consists of construction, operation, and 

maintenance of a 14-inch diameter buried steel NGL pipeline and related facilities that would originate 

southwest of Meeker, Colorado and terminate southeast of Wamsutter, Wyoming. Facilities would include 

a 2,000-foot, 6-inch-diameter lateral, manual shut-off valves at regular intervals, pigging facilities, and two 

meter stations. The pipeline would transport a total of 100,000 barrels of Y-grade NGL per day. Initially, 

20,000 to 30,000 barrels per day (bpd) would be transported; however, the pipe would be designed to 

hold more NGL as the need increases. Should volumes of NGL increase above approximately 70,000 

bpd, a pump station would be constructed at the approximate midpoint of the pipeline route. With the 

pump station installed, the capacity of the pipeline would be 100,000 bpd. Approximately 96 percent of 

the proposed pipeline route would primarily run parallel to existing pipelines and/or other utility corridors. 

 Compact discs of the EA are available for review at the BLM offices listed below. The EA is also 

available for review and downloading from the BLM website at:
