Which organization focuses on regulating the extraction of geological resources in California?

The California Geologic Survey is the organization specifically tasked with regulating the extraction of geological resources in California. Its primary role includes overseeing the responsible use and conservation of California's mineral resources, including the issuance of permits and ensuring compliance with state laws regarding resource extraction. The organization also conducts geological mapping and assessment that contribute to sustainable resource management and public safety.

While other organizations listed engage with geological matters or environmental protection, they do not have the same regulatory focus on geological resource extraction. The California Bureau of Mines, for instance, historically handled mining matters but has been integrated into other agencies over time, thus having a reduced role in current regulatory functions. The California Environmental Protection Agency is primarily concerned with the broader implications of environmental protection and policy rather than specific geological resource extraction. Lastly, the California Geological Society is a professional organization dedicated to the advancement of geological science, which does not have regulatory authority.
