or, if necessary, dried before disposal. If disposed directly into the landfill, the <br /> sludge is mixed with refuse at a minimum solids-to-liquid ratio of 5:1 by weight. <br /> The mixed sludge will not exceed the ultimate moisture holding capacity of the <br /> refuse. <br /> Although sludges that are not dewatered have not been accepted at Forward <br /> for several years, sludges that are not dewatered are permitted to be dried in <br /> WMU H by spreading them on a 1-foot thick, compacted clay pad that is <br /> bermed to prevent runoff. Within 48 hours, the sludge is disced into the clay <br /> pad to allow drying of the sludge. Once dried, the sludge and any soil it has <br /> contacted are moved to appropriate WMUs for disposal. The clay pad is <br /> rebuilt to its original thickness after each drying cycle. <br /> Forward may decide to use sludge as an alternative daily cover (ADC) as <br /> allowed by 27 CCR, Section 20690(b)(4). The LEA will be notified prior to the <br /> use of sludge as an ADC. <br /> Current sludge operations consist only of direct disposal in the landfill or drying <br /> and disposing of sludge in permitted units. To allow recovery and secondary <br /> use of sludge as alternative cover or other soil amendments, the sludge must <br /> be processed and treated using various available methods to meet the <br /> applicable regulatory standards. <br /> Future sludge treatment may include processes that will be mandated by the <br /> final application. Methods using centrifuges are a possibility. Other processing <br /> treatments will be evaluated as they are developed. The proposed processes <br /> .will be discussed with the appropriate regulatory agencies before their use. <br /> 6.4.7.3 ASBESTOS DISPOSAL METHODS <br /> The existing Forward Landfill handles and disposes asbestos containing waste <br /> ACW in accordance with all applicable federal and state regulations. Forward's <br /> ACW Identification Number is EPA I.D. #CAL000190080. <br /> The health and safety of Forward employees and all persons involved in the <br /> disposal of asbestos at the landfill is provided through responsible site <br /> operations and employee medical surveillance.
