Impacts to CTS would be mitigated through implementation of the Community earthwork and on- Department conservation and minimization measures outlined in the BA Development going during (ECORP Consulting,Inc.2009;Appendix D-1-a). These Department's construction measures include the following: satisfaction of this • Silt fencing will be installed around the perimeters of all implementation sediment catchment basins to prevent use as breeding sites. measure by survey or • All excavated,steep-walled holes or trenches more than 6 other appropriate inches deep will be covered with plywood or similar material, documentation. or provided with one or more escape routes constructed of earth fill or wooden planks. • Ground disturbance will be confined to the RMAs and haul roads. • A tightly woven fiber netting,coconut coir netting,or similar material(with openings less than 0.25-inch diameter)will be j used for erosion control or other purposes to ensure that salamanders do not become entrapped. • A water truck equipped with spray bars will be used to dampen unpaved roads for dust control. • To minimize potential for direct impacts to dispersing or migrating salamanders,excavation and hauling of aggregate will be limited to daylight hours. • A permanent rangeland/erosion control seed mix,approved by the County,will be applied to exposed soil surfaces to reduce or minimize invasive weeds. • Vehicle traffic will be restricted to established haul roads, RMAs,and other designated areas. Maintenance of vehicles or other equipment will not occur outside of the designated staging areas,which will be located at least 250 feet from vernal pools,seasonal wetlands,ponds,and riparian habitat. • At least 264.9 acres of land will be restored to conditions comparable or improved relative to pre-mining conditions to provide essential habitat for California tiger salamander and other sensitive species(vernal pool branchiopods,spadefoot i toad etc.).
