The Imperial Irrigation District (IID) and the U.S. Department of the Interior, Bureau of Land Management (BLM) have prepared a Final Environmental Impact Statement / Environmental Impact Report (EIS/EIR) to assess the environmental effects of constructing, operating, and maintaining a transmission line from the Blythe California area to the Southern California Edison Company's (SCE's) Devers Substation, approximately 10 miles north of Palm Springs, California, a distance of approximately 118 miles. The Proposed Project will operate at 500-kV and will provide increased transmission line capabilities from the Blythe area to the Devers Substation to meet existing and future transmission system requirements.

IID is the State of California Lead Agency for the preparation of this EIS/EIR in compliance with the requirements of the California Environmental Quality Act (CEQA) (Public Resources Code Section 21000 et. seq.), CEQA implementing guidelines (California Code of Regulations [CCR] Title 14, Section 15000 et. seq.), and IID's Rules and Regulations to Implement CEQA.

BLM is the federal Lead Agency for the preparation of this EIS/EIR in compliance with the requirements of the National Environmental Policy Act (NEPA), the Council on Environmental Quality (CEQ) regulation for implementing NEPA (40 Code of Federal Regulations [CFR] 1500 - 1508), and the BLM NEPA guidance handbook (H-1790-1).

The purpose of this document is to inform agency decision-makers and the general public about the potential adverse and beneficial environmental impacts of the Proposed Project and alternatives, and recommend mitigation measures that would reduce the significant adverse impacts to the maximum extent possible, and, where feasible, to a less than significant level. The information in an EIS or EIR does not dictate an agency's final determination on a project. However, under CEQA (Public Resources Code Section 21002.1), the state or local agency must adopt feasible mitigation measures or alternatives within its jurisdiction if they would avoid significant environmental effects identified for the Proposed Project.
