Title

Revised SMP-30 Use Permit, Sunol Valley Aggregate Quarry

Description

This proposed project includes the continuation of current Alameda County Surface Mining Permit (SMP) quarry operations as well as the 58-acre quarry expansion. The Sunol Valley Aggregates Quarry operating under SMP 30, which was approved by Alameda County in 1992, authorizes the mining of sand and gravel within a 323-acre area. Under the Revised SMP 30 permit, the Permittee proposes to expand the overall production potential of the quarry by increasing the area under the permit by approximately 58 acres. The expanded quarry pit will occupy approximately 32.5 acres and a haul road and berm will occupy 2.44 acres within the 58-acre expansion area. The project will result in impacts to 34.94 acres of California tiger salamander (Ambystoma californiense) habitat and is expected to result in incidental take of California tiger salamander, which is designated as a threatened species under CESA. Minor Amendment No. 2 makes a simple administrative extension to the deadline in which the completion of the Habitat Management land compensatory mitigation must occur for an additional six (6) months to 30 months from the date of issuance of the ITP. The ITP, as amended by CDFW, authorized incidental take of species listed under CESA that may occur as a result of Project implementation.
