Title

Major Modification (No. 8) Application Case No. LU07-0048 (CUP-3142)

Description

CDFW has executed lake and streambed alteration agreement no. 1600-2014-0087-R5, pursuant to section 1602 of the fish and game code, to the project applicant, Waste Management of California, Inc. The Simi Valley Landfill and Recycling Center (SVLRC) Conditional Use Permit (CUP) boundary for the landfill site is proposed to be expanded approximately 215 acres to increase capacity and the operational life of the SVLRC. Drainages that will be permanently impacted due to the expansion are designated as Drainages A, B, and C, and total 2.00 acres of permanent impact. Drainage A and Drainage B are sparsely vegetated, and are highly disturbed due to historic and ongoing cattle grazing operations. Drainage C is located in an area that supports almost entirely non-native grasses and rural vegetation. Construction activities will involve the sequential grubbing and excavation of separate phases. Phases II through IV will include land clearing, compacting, and preparing each Phase for landfilling. Each Phase contains a number of individual cells. Phase II expansion will permanently fill substantial portions of Drainages A and B. Drainage C and the remaining portions of Drainages A and B will be affected at an undetermined date during later phases of landfill expansion. As the Phase progress, the landfill surface will be contoured to drain runoff to perimeter ditches, and eventually, into permanent sediment basins. Initial impacts to jurisdictional drainages are expected to occur within the year following the execution of this agreement.
