Thurston County is currently updating how mineral resource lands are managed. The Growth Management Act (GMA) requires that counties designate mineral resource lands (RCW 36.70A.060). In the past, the Thurston County mapped only existing mining locations. Going forward, the County is required to map mineral lands more broadly, based on underlying geology. This update consists of four main stages:
1. Identify & classify • mineral deposits in a countywide inventory based on geology;
2. Designate • priority areas where minerals exist and are compatible with land uses;
3. Conserve • through policies that ensure future uses are compatible with mining;
4. Permit • new mining operations will still be reviewed before they are permitted.
The mineral lands update is part of the Comprehensive Plan Update. All final decisions about mineral lands will be part of the overall Comprehensive Plan Update in 2020.
