Public Scoping Meetings Scheduled, Comment Period Extended for Proposed Geothermal Project near Mammoth

The Bureau of Land Management, in cooperation with the Inyo National Forest and the Great Basin Unified Air Pollution Control District, will hold two public scoping meetings to gather input on a proposal to develop additional geothermal resources near Mammoth Lakes in Mono County, California.

The BLM also has extended the public comment period 15 days to May 9, 2011.

The meetings will provide an opportunity for the public, interested groups and local, state and federal agencies to learn about the proposed project and comment on potential environmental issues or concerns. Information gathered during public scoping will help shape the content of a joint Environmental Impact Statement/Environmental Impact Report (EIS/EIR) that is being developed for the proposed project.  Public scoping meetings have been scheduled for both the community of Crowley Lake and the Town of Mammoth Lakes.

The proposed Casa Diablo IV Geothermal Development Project would include construction of a new 33- megawatt geothermal power plant east of U.S. Highway 395 and the Town of Mammoth Lakes.  The new plant would be located north of existing geothermal facilities in the area.  The proposed project would also include an expanded geothermal well field, pipelines to transport geothermal brine to the new power plant and cooled brine to post-production injection wells, and an electric transmission line to interconnect to the existing Southern California Edison substation at Substation Road.

To learn more about the project proposal and to provide written comments in person, the public is encouraged to attend either of the following scheduled meetings:

Crowley Lake: April 18, 6 p.m.

Crowley Lake Community Center
458 South Landing Road
Crowley Lake

Mammoth Lakes: April 19, 6 p.m.

1000 Forest Trail
Town of Mammoth Lakes
