Document Description
Revision to approved Surface Mine Permit SMP00102 to allow an approximately 59-acre expansion of an existing, 110.3-acre surface mine to include additional extraction of gypsum, as well as temporary stockpiling of excavated surface materials (overburden) for a period of 50 years. The proposed expansion would occur in two phases, with the first to occur through the year 2060, and the second, final phase comprising the last 10 years of the permit’s approval through 2070. The expanded mine would comprise 169.5 acres of a total 611-acre Project site. The total volume to be removed is estimated at 61 million tons over the lifetime of the mine. Following conclusion of Phase Two, the entirety of the mine, in addition to 21 acres outside of the footprint of proposed operations, would be “reclaimed” – restored in accordance with a revised Reclamation Plan, requirements of the Surface Mine and Reclamation Act (SMARA) and County Ordinance 555 – ultimately returning a total of 190.5 acres to open space, habitat and restored drainage courses.
