The updated PCPCMP will include the proposed final cover design configuration in compliance with current State and Federal regulatory requirements. The final cover system and the post-closure maintenance plan for the expansion area will be generally consistent with the current plan or an approved alternative final cover design utilizing a monolithic soil cover, as allowed under 27 CCR, Section 20080(b). Figure G shows conceptual final cover cross-sections. The actual final cover to be placed on the landfill will be designed by FL and approved by the RWQCB at the time either phased or final closure activities are implemented. 5.4 OPERATIONAL MODIFICATIONS The proposed operational modifications (changes) at the FL include solidification of higher liquid content wastes, the individual quantification of the beneficial reuse materials and limited reuse soil and an increase in the maximum traffic volume. Forward proposes no change to the receipt of up to 8,668 tons per day of refuse. However, the materials for beneficial reuse, limited reuse soil, and materials delivered to the MRF will be quantified separately and considered as an increase in the overall inflow rate for the FL. The following sections describe the operational changes proposed and the types and quantities of beneficial reuse materials to be utilized at the FL. 5.4.1 HIGH MOISTURE CONTENT WASTE SOLIDIFICATION Forward is proposing to accept non-hazardous liquid waste and sludge for solidification and disposal in the refuse fill area. Liquid waste means any non- hazardous waste material that is determined to contain "free liquids" as defined by United States Environmental Protection Agency (EPA) SW-846 Method 9095 A. All bulk and semi-solid wastes that do not pass the paint filter test (EPA-846- 9095A) will be solidified on site by mixing with a solidification agent (i.e., ash, soil, processed green or food material, etc.). After the waste has been solidified sufficiently to pass the paint filter test, the material will be transported to the working face for disposal. An example of the types of non-hazardous wastes which may require solidification include, but are not limited to, sewage sludge, off-specification food and other consumer products, and by-products from various food processing and other industrial operations.
