Summary

Defines key words used in the chapter. "Secretary" means the U.S. Secretary of the Interior. "Geothermal lease" means a lease issued under this chapter. "Geothermal resources" covers steam, hot water, hot brines, gases from fluids put into geothermal formations, the heat or energy in those formations, and any byproducts from them. "Byproduct" means any mineral (not including oil, hydrocarbon gas, or helium) found with geothermal steam that is worth less than 75 percent of the steam’s value or is not worth extracting by itself because of small amount, poor quality, or technical difficulty. "Known geothermal resources area" means an area that, in the Secretary’s judgment, experienced people would think has good enough prospects for geothermal recovery to justify spending money. "Significant thermal features within units of the National Park System" includes thermal features listed or designated in Section 1026(a)(1) and in the Federal Register notice of August 3, 1987 (Vol. 52, No. 148 Fed. Reg. 28790), Crater Lake National Park, features in Big Bend National Park and Lake Mead National Recreation Area proposed as significant in the Federal Register notice of February 13, 1987 (Vol. 52, No. 30 Fed. Reg. 4700), and any features later added under section 1026(a)(2). "Direct use" means using geothermal resources for energy needs other than making electricity, such as commercial, home, farm, or public facility heating.

(c)“geothermal resources” means (i) all products of geothermal processes, embracing indigenous steam, hot water and hot brines; (ii) steam and other gases, hot water and hot brines resulting from water, gas, or other fluids artificially introduced into geothermal formations; (iii) heat or other associated energy found in geothermal formations; and (iv) any byproduct derived from them;
(d)“byproduct” means any mineral or minerals (exclusive of oil, hydrocarbon gas, and helium) which are found in solution or in association with geothermal steam and which have a value of less than 75 per centum of the value of the geothermal steam or are not, because of quantity, quality, or technical difficulties in extraction and production, of sufficient value to warrant extraction and production by themselves;
(e)“known geothermal resources area” means an area in which the geology, nearby discoveries, competitive interests, or other indicia would, in the opinion of the Secretary, engender a belief in men who are experienced in the subject matter that the prospects for extraction of geothermal steam or associated geothermal resources are good enough to warrant expenditures of money for that purpose.

(1)Thermal features within units of the National Park System listed in section 1 1026(a)(1) of this title and designated as significant in the Federal Register notice of August 3, 1987 (Vol. 52, No. 148 Fed. Reg. 28790).
