Document Description
Johe Ranch Mining Project, by Diatom, LLC (project proponent), is requesting a Conditional Use Permit (CUP) for a 93.67-acre surface mining operation and development of a reclamation plan on approximately 331-acre project site, in accordance with the Surface Mining and Reclamation Act (SMARA) of 1975. The project proponent proposes to employ open pit mining techniques to mine diatomaceous earth (a mineral suitable for industrial uses including the production of cement) and overburden material (earth overlying the diatomaceous earth, proposed to be sold for use as a landfill liner, and to solidify liquid waste after it is deposited in a landfill). As proposed, all overburden material (typically considered as non-marketable waste in the mining industry) which is excavated will be exported from the project site and sold; as such, no waste is proposed to be generated.
