Title 30 › Chapter 23— GEOTHERMAL RESOURCES › § 1001
Defines key words used in this chapter. Secretary means the Secretary of the Interior. Geothermal lease means a lease issued under this chapter. Geothermal resources include steam, hot water, and hot brines that occur naturally or that form after fluids are put into geothermal formations, the heat or other energy in those formations, and any byproducts from them. Byproduct means a mineral (not oil, hydrocarbon gas, or helium) found with geothermal steam that is worth less than 75% of the steam’s value or is not worth extracting by itself because of small amounts, poor quality, or technical problems. Known geothermal resources area means a place that, in the Secretary’s judgment, has geology or other signs that would lead experienced people to believe extracting geothermal steam or related resources is likely enough to justify spending money. Significant thermal features in National Parks include the thermal areas listed in section 1026(a)(1) and named in the Federal Register notice of Aug. 3, 1987 (Vol. 52, No. 148, p. 28790); Crater Lake National Park; thermal areas in Big Bend National Park and Lake Mead National Recreation Area noted in the Feb. 13, 1987 Federal Register (Vol. 52, No. 30, p. 4700); and any units added under section 1026(a)(2). Direct use means using geothermal resources for energy needs — like commercial, residential, agricultural, or public facility uses — but not for producing electricity for sale.
