Geothermal Technical Working Papers:
Interagency Collaboration with DOE's Geothermal Technologies Office and DOI's Bureau of Land Management

The Department of Energy's (DOE) Geothermal Technologies Office (GTO) and the Department of the Interior's (DOI) Bureau of Land Management (BLM) committed to develop and implement a formalized working agreement that will facilitate a technical evaluation of environmental impacts of geothermal technologies. This analysis will provide a comprehensive reference document which can form an analytical basis for future agency National Environmental Protection Act (NEPA) documents. The analysis will take the form of technical working papers that will be integrated into the NEPA processes of participating Agencies via internal mechanisms: BLM could issue an Instruction Bulletin/Memorandum; and DOE could issue guidance documents to Program and Field Offices. Technical working papers have been drafted for the following five topics:

  • Pre-production Drilling
  • Production Drilling
  • Downhole Fluids
  • Produced Fluids
  • Hydraulic Stimulation

These papers are currently under Agency review and will be available for public comment upon completion.
