SUPPLEMENTARY INFORMATION: 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.

    Authority:  40 CFR 1506.6, 40 CFR 1506.10.

Bishop Field Manager.
