SUPPLEMENTARY INFORMATION: Back to Top
The Draft EIS/EIR analyzes the potential impacts of authorizing the proposed Casa Diablo IV Geothermal Development Project near the Town of Mammoth Lakes in Mono County, California. In accordance with the Geothermal Steam Act of 1970, as amended (30 U.S.C. 1001 et seq.), the BLM Bishop Field Office is the lead Federal agency responsible for permitting the proposed project and for completing the required environmental analysis under NEPA. The USFS Inyo National Forest is a cooperating Federal agency. The GBUAPCD is the lead State agency responsible for permitting the proposed project and for completing the required environmental analysis under the CEQA.
The purpose and need for action is to respond to an application to construct and operate the proposed Casa Diablo IV Geothermal Development Project on Federal geothermal leases administered by the BLM Bishop Field Office. The proposed project would be located on Inyo National Forest lands and adjacent private lands within portions of Federal geothermal leases CACA-11667, CACA-14407, CACA-14408, and CACA-11672. The leases proposed for development are part of an existing geothermal unit, which is currently providing energy sufficient to power three operating geothermal plants.
The applicant's proposed action includes the construction of a new 33-MW binary geothermal power plant, which would be the fourth geothermal plant in the vicinity; up to 16 wells for production and reinjection, drilled to an approximate 1,600- to 2,500-ft depth; and associated pipelines. A 650-ft long transmission line is proposed to interconnect the new power plant to the existing Southern California Edison (SCE) substation at Substation Road. The proposed Casa Diablo IV plant, access roads, well pads, pipelines and transmission line would occupy approximately 80 acres. Of the 16 proposed production/injection well locations, 14 were previously analyzed and approved by the BLM as exploration wells in EA-170-02-15 (2001) and EA-170-05-04 (2005). Three of these exploration wells have already been drilled as of the time of the publication of this notice. The proposed well field contains two existing production wells and associated pipelines that currently serve the three existing power plants in the area.The BLM published a Notice of Intent (NOI) to prepare a joint EIS/EIR on March 25, 2011, in the Federal Register (76 FR 16806). Publication of the NOI initiated a public scoping period, which included two public scoping meetings. Comments received through the scoping process and consultations carried out pursuant to Section 106 of the National Historic Preservation Act and other Federal mandates identified the following issues and concerns that have been incorporated into the Draft EIS/EIR: Potential effects on air quality, biological resources including vegetation and wildlife, cultural resources and Native American concerns, public health and safety, recreation resources, and surface and groundwater resources.
Alternatives identified and evaluated in the Draft EIS/EIR include: Alternative 1, the applicant's proposed action which is outlined above; Alternative 2, which considers an alternative location for the proposed power plant; Alternative 3, which considers alternative pipeline alignments in Basalt Canyon and slightly alters the location of one proposed well; and Alternative 4, the no action alternative which would limit geothermal development activities on the affected leases to those previously authorized by the BLM. In accordance with NEPA (40 CFR 1502.14(e)), the BLM and USFS have identified Alternative 3 as the preferred alternative. The GBUAPCD has also identified Alternative 3 as the “environmentally superior alternative” pursuant to the CEQA (14 C.C.R. 15126.6(e)(2)).
Public comments and information submitted, including names, street addresses, and email addresses of persons who submit comments, will be available for public review at the above address during regular business hours (8 a.m. to 4 p.m.), Monday through Friday, except holidays.
Before including your address, phone number, email address, or other personal identifying information in your comment, you should be aware that your entire comment—including your personal identifying information—may be made publicly available at any time. While you can ask us in your comment to withhold your personal identifying information from public review, we cannot guarantee that we will be able to do so.
