Document Description
The Niles Canyon Quarry, owned by SRDC Inc., was purchased in 1984. SRDC renewed the reclamation plan in 1996 for mining and reclamation, as allowed by the Alameda County (County) Surface Mining and Reclamation Plan Permit (SMP) 34. The approved 1996 mine plan was designed with the expectation that the property would be mined to consist of two pits, with a total of 1,850,000 cubic yards (cu. yd.) of material to be excavated over a 25-year period. The quarry has not been in operation since 2012. The Niles Canyon Quarry site has not been in compliance with many of the its SMP conditions of approval (COA), the California Surface Mining and Reclamation Act (SMARA), County Surface Mining Ordinance (SMO), and County zoning requirements, which has led to County enforcement actions, including notices of violation and an order to comply. A key element of bringing the site into compliance is the development and processing of a reclamation plan amendment. This project description provides a description of the major elements of the reclamation plan amendment and will be used by the County to evaluate the environmental impacts of the construction and implementation of the reclamation plan amendment. See NOC for full details.
