AltaRock Engineered Geothermal System Demonstration Project
Document Type
EA - Environmental Assessment

Present Land Use
Federal land administered by the Bureau of Land Management

Document Description
The project would involve deepening existing injection well E-7 and injecting water into the rock formation below the existing steam reservoir at NCPA's Geysers facility. The purpose of the injection is to create a new, deeper steam reservoir that can be tapped to provide steam for the existing NCPA geothermal energy plants at the facility. A new well E-8 would be drilled adjacent to well E-8 for purpose of extracting steam from the new reservoir. If the demonstration project proves successful, NCPA may enter into an agreement with AltaRock to provide it steam from the new well. The proposal area does not include any site listed by the state as containing hazardous materials or wastes. The NCPA facility operates on federal land under lease from the Bureau of Land Management (BLM). Before the project can operate, it will need a permit from the BLM. A joint Environmental Assessment/Initial Study (EA/IS) has been prepared to analyze the potential environmental effects of the project under both the CEQA and NEPA.
