Geothermal Steam Act of 1983

Geothermal Steam Act of 1983 - Amends the Geothermal Steam Act of 1970 to authorize the Secretary of the Interior to issue geothermal leases in any land administered by another Federal agency or department, including public, withdrawn, or acquired lands.

Redefines the term "known geothermal resource area" to mean an area where the prospects for extraction of geothermal resources for generating electricity in commercial quantities warrant substantial expenditures for that purpose.

Requires lands within a known geothermal resource area which are offered for lease and which receive no bids to be declassified and leased to the first qualified applicant.

Entitles the first qualified applicant for a lease not within a known geothermal resource area to a noncompetitive lease if the land involved is not designated a known geothermal resource area within one year of the application being filed and before the lease is issued. Permits such an applicant to match the highest competitive bid for such land if it is designated as a known geothermal resource area within such time period.

Entitles the applicant or lessee responsible for the exploration resulting in the designation of a known geothermal resource area to a noncompetitive lease for all lands in the designated area for which the applicant lessee had filed applications prior to such exploration.

Requires that geothermal leases provide for a royalty of: (1) not less than ten percent or more than 15 percent of the value of the energy produced and sold for electrical generation; or (2) not less than five percent or more than 15 percent of the value of energy produced and sold for nonelectrical use.

Eliminates the limits on the duration of: (1) geothermal leases with respect to which geothermal steam is produced or utilized in commercial quantities (under current law, such leases may not be extended beyond the primary term of ten years for more than 40 additional years); and (2) leases with respect to which actual drilling operations were commenced before the end of their primary terms and geothermal steam is produced or utilized in commercial quantities (under current law, such leases may not be extended beyond the primary term for more than 35 additional years).

Provides that, in certain cases, the term "commercial quantities" shall include a drilled well and either a bona fide sale for delivery to utilization facilities installed or to be constructed or proof of commitment to construct such facilities. Requires the Secretary to grant extensions of up to 15 years on a primary lease if construction of such facilities has not been possible due to administrative delays beyond the lessee's control or due to the demonstrated marginal economics of such facilities.

Increases the State-wide acreage limitation for Federal geothermal leases from 24,480 acres to 51,200 acres. Authorizes the Secretary to increase the maximum holding in any one State, after public hearings, to a maximum of 115,200 acres. Exempts from such limitations those leases which contain wells capable of commercial production and those leases operated under approved operating, drilling, or development contracts.

Permits readjustment of geothermal lease terms and conditions at 20 year intervals beginning: (1) 20 years after the date commercial production is commenced for nonelectric uses; and (2) 20 years after the first generation of electricity for sale for electric generation use.

Prohibits the Secretary from issuing leases on the acquired lands of other Federal agencies or departments without the consent of the agency or department head.

Directs the Secretary to identify and publish in the Federal Register the geothermal features located on lands within national parks and monuments. Authorizes the issuance of geothermal leases on Federal land within specified geographic zones outside such parks or monuments only after a determination that geothermal exploration activities pursuant to such a lease will not adversely affect nationally significant geothermal features.

Authorizes the issuance of free use permits for: (1) noncommercial applications of geothermal resources in lands administered by the Secretary; and (2) surface use and use of geothermal resources for the continued operation of any geothermal energy research and development facility, pilot plant, or demonstration facility the Federal interest in which is transferred. Permits the head of each Federal agency to develop, for the benefit of the agency, the geothermal energy resources within the lands under its jurisdiction, provided such use is in the public interest and will not deter commercial development which might be more beneficial.
