U.S. Federal Agencies Publish Final PEIS on Western Energy Corridor Designation

December 5, 2008 // Published as a news service by IHS

The U.S. Department of the Interior's (DOI) Bureau of Land Management (BLM) and the U.S. Departments of Energy (DOE), Agriculture (DOA) and Defense (DoD) prepared the Final PEIS as part of their work to implement Section 368 of the Energy Policy Act of 2005.

The proposed energy corridors would facilitate future siting of oil, gas and hydrogen pipelines, as well as electricity transmission and distribution facilities on federal lands in the West to meet the region's increasing energy demands while mitigating potential harmful effects to the environment.

"Up to now, federal land management agencies have often designated energy corridors and rights-of-way when local projects were proposed," said Assistant Secretary of the Interior C. Stephen Allred.

"Designating energy corridors using a PEIS allows the participating agencies to mitigate environmental effects and reduce conflicts with other uses of federal land. The results of this work will speed the process of siting energy infrastructure on federal lands in the West."

The Energy Policy Act of 2005 directs the secretaries of the DOA, DoD, DOE and DOI to designate energy transport corridors for oil, gas and hydrogen pipelines and electricity transmission and distribution facilities on federal lands in Arizona, California, Colorado, Idaho, Montana, Nevada, New Mexico, Oregon, Utah, Washington and Wyoming.

The act further directs that environmental reviews be completed for the designation of such corridors and that the designated corridors are incorporated into the relevant agency land-use and resource management plans or equivalent plans.

Energy transport corridors are agency-preferred locations where pipelines and transmission lines may be sited and built in the future. Having a network of corridors that could accommodate transportation systems for multiple energy types potentially minimizes the proliferation of energy utility rights-of-way on the federal landscape, said DOE. 82% of the corridors analyzed in the Final PEIS are located on BLM-managed lands, while 16% are on U.S. Forest Service lands.

The remaining proposed corridor segments are on lands managed by the Interior's Bureau of Reclamation and National Park Service, or by the DOD. Individual projects proposed for these corridors would undergo further, project-specific environmental analysis before being granted permits or rights-of-way.

Corridors were sited using a four-step process that identified a number of important lands and resources to be avoided to the fullest extent possible. The agencies examined factors that constrain where a network of energy transport corridors could be located - including topographical, environmental and regulatory constraints - as well as the overall suitability of particular lands to support development and operation of energy transport infrastructure.

In some cases, corridors intersect or approach sensitive lands or resources. Most often these intersections follow existing infrastructure such as highways, transmission lines or pipelines to avoid placing corridors in "greenfield" (undeveloped) locations.

The PEIS identifies a number of requirements that will help ensure that energy transport projects within Section 368 energy corridors are planned, implemented and operated in a manner that protects and enhances environmental resources.

Prepared under provisions of the National Environmental Policy Act, the Final PEIS outlines the potential environmental effects of two alternatives developed, in part, by using comments received during a scoping period in fall 2005, public responses to preliminary maps published in June 2006 and public comments on the draft PEIS during a 90-day comment period earlier this year.

The agencies worked closely with local federal land managers as well as local government agencies to ensure that the proposed corridors were consistent with local land management responsibilities and resource constraints.

In preparing the Final PEIS, the agencies reviewed and considered all of the comments received on the draft during the 90-day comment period and made revisions to the PEIS and adjustments to the corridors as appropriate and applicable, said DOE. Aspects of the alternatives were clarified or expanded to provide additional information on the purpose and need for corridor designation, potential impacts to resources, locations of sensitive resources or areas or other concerns.

The Final PEIS and related documents, including detailed maps, are available at the West-wide Energy Corridor Programmatic EIS Information Center.
