layer will be planted with drought-resistant native vegetation having appropriate <br /> root depths for the vegetative layer thickness. <br /> 3.2.3 SOURCES OF COVER MATERIAL <br /> Materials for construction of the final cover will be obtained from soils stockpiled <br /> during excavation of the waste management units or imported, if necessary. The <br /> CQA program for the final cover construction is included in Appendix A and <br /> summarized in the following section. <br /> 3.2.4 FINAL COVER CONSTRUCTION QUALITY ASSURANCE <br /> The construction of the final cover system shall be carried out in accordance <br /> with the CQA Plan included in Appendix A. The implementation of the CQA <br /> Plan will provide documentation that suitable materials and standard <br /> construction practices are used to place the final cover system and to document <br /> that placement is consistent with the closure plan design specifications in 27 <br /> CCR, Section 20323 and 20324. Elements of the CQA Plan include: project <br /> description and definitions, qualifications and responsibilities, requirements for <br /> the final cover evaluation, inspection standards, testing frequencies, meetings <br /> and documentation. This information will be collected during final closure <br /> construction and incorporated into the project's final closure construction CQA <br /> Report which will be submitted to the appropriate agencies for recording and <br /> reporting purposes. The design professional who prepares the CQA Plan shall <br /> be a registered civil engineer or certified engineering geologist. <br /> 3.3 FINAL GRADING <br /> This section describes the proposed final grading contours for the Forward <br /> Landfill which were designed to promote lateral run-off of surface water and <br /> minimize the effects of settlement. Perimeter maintenance and deck access <br /> roads are also designed to provide for maintenance of the final cover and <br /> environmental control systems throughout the post-closure maintenance period. <br /> The final grading plan (Drawing 4 of the JTD) presents the landfill configuration <br /> after closure. Upon completion of refuse placement, the deck area will be set at <br /> a minimum gradient of three percent which will provide adequate drainage from <br /> the top deck, while taking into account projected landfill settlement (see Section <br /> Forward Landfill PCPCMP 3-5 <br /> L:\Allied\2000.193\Reports\FinaIPCPCMP:FL-sec3.doc:5/21/02 BRYAN A.STIRRAT&ASSOCIATES <br />
