Title 30 › CHAPTER 23 — GEOTHERMAL RESOURCES › § 1026
The Secretary must keep a list of important thermal features (as defined under section 1001(f)) found in National Park System units. The list includes many parks, for example Mount Rainier, Crater Lake, Yellowstone, Hot Springs, Hawaiʻi Volcanoes, Haleakala, Lake Mead, Big Bend, Lassen, and several Alaska parks such as Katmai, Wrangell‑St. Elias, Gates of the Arctic, Aniakchak, Lake Clark, and Bering Land Bridge, plus John D. Rockefeller, Jr. Memorial Parkway. The Secretary can add more features after notice and public comment. To decide if a feature is “significant,” the Secretary must weigh size and uniqueness, scientific and geologic importance, how natural and undisturbed it is, and how important it is to the park’s purpose. The Secretary must also run a monitoring and research program with the U.S. Geological Survey, starting with features near current or proposed geothermal development and also covering areas with potential development. When someone applies for a geothermal lease, the Secretary must use scientific evidence to decide if exploration or development is likely to cause a significant bad effect on a listed thermal feature. If it is likely, the lease must not be issued for those lands. Leases and drilling permits must include protections when needed, such as reinjecting geothermal fluids, annual reporting, continuous monitoring, and stopping work if serious harm is happening (and ending the lease if harm cannot be fixed in a reasonable time). The Secretary of Agriculture must consider these effects before allowing leasing on lands it manages. The ban on leasing in the Island Park Geothermal Area shown in the “Final Environmental Impact Statement of the Island Park Geothermal Area” (January 15, 1980, p. XI) and provided for in Public Law 98–473 remains in effect.
