BLM Extends Comment Period on Public Input on Proposed SunZia Southwest Transmission Project

Santa Fe, N.M. – The Bureau of Land Management (BLM) is extending the public comment period on the proposed SunZia Southwest Transmission Line Project through August 28, 2009. The initial public scoping comment period was scheduled to end July 13, 2009; however, due to numerous requests from interested groups, organizations and citizens, the BLM has made a decision to grant an extension to the formal comment period.

“The extended scoping comment period will give the public more time and an additional opportunity to share comments and concerns and identify issues and alternatives to be considered during the Environmental Impact Statement (EIS) process,” said Linda Rundell, BLM New Mexico State Director. The BLM is the lead federal agency for a proposal by SunZia Transmission LLC to construct, operate, and maintain a high-voltage 500 kilovolt (kV) power transmission line (or two parallel lines) across southern New Mexico and Arizona. SunZia’s proposed transmission line would be about 460 miles in length and originate at a new substation site in either Socorro or Lincoln County, New Mexico; it would terminate in Pinal County, Arizona. The proposed line – or parallel lines - would be located on federal, state, and private lands. The purpose of the project would be to transport electricity, generated primarily from renewable resources, to western power markets and centers. 

The BLM, as the lead federal agency, will oversee the preparation of the EIS that will identify environmental impacts and evaluate alternatives for the project. The final agency decision for the proposed route, which would involve decisions on federal Right-of-Way designations, will only affect public lands administered by the BLM.

Cooperating agencies invited to participate include the U.S. Fish and Wildlife Service, Bureau of Reclamation, U.S. Army Corps of Engineers, the New Mexico State Land Office and the Arizona State Land Department and other state agencies and local governments. Consultation will also occur with tribal governments.

Comments can be made to the BLM via the BLM Project Website at, via the project email address at,  or in writing to the Bureau of Land Management, SunZia Transmission Line Project, P.O Box 27115, Santa Fe, NM 87502-0115. Deliveries will be accepted via courier/hand delivery to the Bureau of Land Management, SunZia Transmission Line Project, 1474 Rodeo Road, Santa Fe, NM 87505.

The BLM manages more than 245 million acres of public land, the most of any Federal agency. This land, known as the National System of Public Lands, is primarily located in 12 Western states, including Alaska. The BLM also administers 700 million acres of sub-surface mineral estate throughout the nation. The BLM's mission is to sustain the health, diversity, and productivity of America’s public lands for the use and enjoyment of present and future generations. In Fiscal Year 2015, the BLM generated $4.1 billion in receipts from activities occurring on public lands.
