Federal Geothermal Environmental Review(9-FD)

A geothermal developer needs to consider many environmental issues when developing a geothermal project. This section discusses the environmental review process under the National Environmental Policy Act (NEPA) and many related environmental topics typically found in a NEPA review document, including:

  • Cultural Resources;
  • Biological Resources;
  • Land Use Assessment;
  • Water Quality
  • Air Quality; and
  • Waste & Hazardous Materials.

Environmental Review

NEPA established policy and goals for the protection, maintenance, and enhancement of the environment and outlines the process for implementing these goals within federal agencies. Projects that involve a "major federal action" trigger the NEPA process. Generally, NEPA review is necessary if the project is on federal land, the federal government owns the mineral estate, the project receives federal funding or support, or if where the project requires a federal permit.

The level and scope of the NEPA review will vary depending on the nature of the project and the level of involvement by federal agencies. A small amount of project activities may qualify as “casual use” and are otherwise exempt form NEPA review. Other project activities are “categorically excluded” from NEPA review by statute or regulation. Most projects activities require either an Environmental Assessment or a more detailed and time-consuming Environmental Impact Statement. Finally, where previous NEPA review of related activities is sufficient, certain project activities may be exempt from NEPA review after a Determination of NEPA Adequacy.

Generally, NEPA review considers the social, environmental, and economic impacts of a proposed activity and considers alternatives. NEPA review takes a “hard look” at the proposed activity by encouraging agency cooperation, soliciting public input and conducting tribal consultation where applicable.

NEPA review is conducted by a "lead agency.” A “lead agency" is the federal agency responsible for producing the NEPA document(s) and coordinating with any other federal, state, or tribal agencies. For most projects, the lead agency will be the Bureau of Land Management (BLM), the United States Forest Service (USFS), the Department of Energy (DOE), or the United States Department of Defense (DOD). Each agency has specific regulations for implementing NEPA, however, all agencies’ regulations derive from and are guided by the procedural NEPA requirements outlined in the Council on Environmental Quality (CEQ) Regulations.

For any project, developers should initially determine which agency will be the “lead agency” for NEPA review. While not necessarily dispotive, developers can start by contacting the applicable land management agency based on the project location. If the applicable land management agency (likely BLM or USFS) is not the lead agency for project NEPA review, the agency will likely be able to assist the developer in determining which other agency is the lead agency for the project (potentially DOE or DOD).

Type of Environmental Review (Leasing Stage): Typically an Environmental Assessment (EA) is conducted for individual leases. An Environmental Impact Statement (EIS) may be required for programmatic environmental reviews or when reviewing multiple lease parcels in a single review.

Type of Environmental Review (Non-Invasive Exploration): A categorical exclusion is available for all activities covered under a Notice of Intent to Conduct Geophysical Exploration (NOI), subject to extraordinary circumstance review. Where the activity results in an extraordinary circumstance, an EA or EIS is required.

Where the activity results in an extraordinary circumstance, an EA or EIS is required.
Type of Environmental Review (Invasive Exploration): Temperature Gradient Holes are permitted under a categorical exclusion and subject to the same conditions as non-invasive exploration as discussed above. Any other exploration drilling activity to confirm the existence of a geothermal resource will likely require an EA.
