CERTIFICATION 22. San Joaquin County will retain a registered civil engineer to certify that all WMUs at this facility meet the construction or prescriptive standards and performance goals of Subchapter 15. CEQA CONSIDERATIONS 23. The San Joaquin County Planning Commission has certified a final environmental impact report (EIR) on the project in accordance with the California Environmental Quality Act, (Public Resources Code Section 21000, et seq. ) , and the State Guidelines. The project may have the following significant impacts on water quality: Increased sedimentation in the South Fork of Paddy Creek below the landfill ; Potential contamination of ground water from leachate generated at the landfill ; Elimination of 1 - 10 acres of wetland habitat. 24. The Board has reviewed the EIR and these WDRs will mitigate or avoid the significant impacts on water quality as follows: construction of wide, shallow perimeter ditches, with vegetation encouraged in the ditch bottoms, will mitigate the increased sedimentation of surface waters; construction of a clay liner and LCRS in each WMU will mitigate possible leachate migration to groundwater; developement and implementation of a wetland restoration plan will mitigate the elimination of the wetland habitat.
