The Bureau of Land Management recently released the scoping summary report for the proposed Southline Transmission Line project, ending the 90-day scoping period for the project environmental impact statement.
BLM and Western, as joint lead agencies in the preparation of the EIS, held six open houses in New Mexico and Arizona in May during the scoping phase. The scoping phase gives the public the opportunity to learn about a proposed project, share concerns and provide comments on what potential impacts should be analyzed in the draft EIS expected in 2013.
Major concerns discovered during the scoping process included the NEPA process and BLM’s management plan amendment, wildlife impacts and socioeconomic impacts.
Southline Transmission, LLC, proposes to construct, operate and maintain a 360-mile, high-voltage power line from Afton, N.M., to Saguaro substation northwest of Tucson, Ariz. About 240 miles would be new construction of a 345-kilovolt line on mostly BLM land while the rest would be an upgrade to an existing Western line. If completed, the line will add 1,000 megawatts of transmission capacity to the southwest.
After receiving a number of requests, the Department of Interior’s Bureau of Reclamation and U.S. Park Service decided to extend the scoping period for a new Environmental Impact Statement related to the operation of Glen Canyon Dam on the Colorado River from Dec. 30 to Jan. 31.
During the scoping period, agencies determine what factors to consider in the EIS and gather comments from the public to identify social, economic and environmental concerns and project alternatives to evaluate.
The EIS, which is jointly led by Reclamation and the Park Service, involves adopting a Long-Term Experimental and Management Plan for the Operation of Glen Canyon Dam.
The plan, the first comprehensive review of dam operations in 15 years, will ensure that regulated flows on the Colorado River meet the goals of supplying hydroelectricity and water for communities, agriculture and industry; protecting endangered species; and lessening the impact on downstream ecosystems, including the Grand Canyon and Glen Canyon.
Changes to current water flows will be evaluated as “alternatives” in the EIS.

Western is involved with many transmission projects throughout its 15-state territory. To ensure reliable service the system often needs upgrades, additions or other modifications. So in addition to maintenance of Western’s existing infrastructure, the agency often is involved with supporting or leading proposed construction projects to keep the bulk electrical system running smoothly.
You can learn more about several construction projects Western is currently involved in on our “Infrastructure projects” webpage.
As you click through the proposed upgrades, you will see Western’s strong commitment to complying with the National Environmental Protection Act. For nearly all projects, we conduct environmental studies to determine the impact these infrastructure projects will have on the area’s land, habitat, water, endangered and protected species and cultural and historical resources.
From our website you can see the proposed projects and construction planned for your local area to ensure the lights stay on in your home or business.
