Subsurface geologic information.
RCW 43.92.090
in effect(1) The geological survey shall compile and maintain a comprehensive database of publicly available subsurface geologic information relating to Washington state. The geological survey must make the database available to the public in a searchable format via the geological survey's website. (2) The subsurface geologic information contained on the website should include, but is not limited to, the following: (a) Temperature gradient logs; (b) Geothermal well records; (c) High resolution magnetotelluric surveys; (d) High resolution gravity surveys; (e) Geothermal play fairway studies; (f) Three-dimensional reflection seismic surveys; and (g) Rock properties databases. (3) The geological survey must: (a) Coordinate with federal, state, and local agencies, and tribal governments, to compile existing subsurface geologic information; (b) Acquire, process, and analyze new subsurface geologic data and update deficient data using the best practicable technology; (c) Using available data, characterize the hazard of induced seismicity for high-potential geothermal play areas. Results of induced seismicity hazard studies must be made publicly available and updated as new information is available; and (d) Provide technical assistance on the proper interpretation and application of subsurface geologic data and hazard assessments.
