Geothermal Laws and Standards

Here you can find lists of U.S. federal geothermal laws and statutes under mineral, lands, and mining; conservation; and public health and welfare. You'll also find U.S. geothermal standards covering terminology, thermal performance specifications, testing of seal materials, and sampling for chemical analysis.

Mineral Lands and Mining

• Geothermal Steam and Associated Geothermal Resources

• Geothermal Energy Research, Development, and Demonstration

Conservation

• Public Utility Regulatory Policies

Public Health and Welfare

• Energy Conservation and Resource Renewal

U.S. Geothermal Standards
