Las Cruces, NM – The Draft Environmental Impact Statement, or EIS, for the proposed Southline Transmission Line Project was released today by the Bureau of Land Management and the Western Area Power Administration.

Southline Transmission, LLC, proposes building the 360-mile line from near Las Cruces, NM, to Tucson, AZ. The line would cross BLM-managed public land, state land, and private property. Southline indicates the line would improve reliability of the electrical grid and help facilitate renewable energy markets in the region.

With the release of the Draft EIS, the BLM and Western are commencing a 90-day comment period. The comment period ends July 10, 2014. Members of the public will have the opportunity to learn about the proposed project at a series of public hearings in New Mexico and Arizona. They can also make comments on the Draft EIS at the meetings.

Southline Transmission plans to construct a high-voltage power line in two segments. The first segment, 240 miles long, would be a new double-circuit 345-kilovolt (kV) line from a substation in Afton, New Mexico (south of Las Cruces), to the Apache Substation south of Willcox, Arizona. The second segment would be an upgrade and a rebuild of 120 miles of existing transmission lines between the Apache Substation and a substation north of Tucson.
