LEA Advisory 20 Attachment- Inspection Guidance for SW Landfills Page 28 of 52 all fire control requirements of local fire control authorities or with fire control provisions in their SWFP. If it is determined that requirements are not being met, the local fire authority should be informed. The RWQCB should be informed of discharges resulting from fire or fire extinguishing. Discharges resulting from tire fires should be brought to the attention of the local Hazardous Materials Team and the Department of Toxic Substances Control (DTSC). Inspection guidance for tire facilities will be provided in a subsequent LEA Advisory. Leachate 17704 Leachate Control The operator shall take adequate steps to monitor, collect, treat, and effectively dispose of leachates. As defined in Section 17225.40, "leachate includes liquid that has come into contact with or percolated through waste materials and has extracted or dissolved substances therefrom." Leachate can contain pathogens, heavy metals, and a variety of organic chemicals including known carcinogens such as benzene and vinyl chloride. Note that water quality impairment can occur due to landfill gases that have entered groundwater. If the inspector is aware of potential or existing contamination of ground and surface waters by leachate, the RWQCB should be informed. During inspection preparation and review of the facility files, the inspector should contact the appropriate staff person at the applicable RWQCB to determine if they have discovered problems with the facility's leachate collection and recovery system and/or leachate management program. It is important to take detailed notes during the conversation with the RWQCB representative. This information, in conjunction with field observations, is used in evaluating the operator's compliance with the leachate standard and might be included in an inspection report. Inspectors should always make their own observations during the inspection and document any observations supporting or expanding on the status of the facility's leachate collection and recovery system and/or leachate management program. A violation will exist if: . the inspector observes liquid that has percolated through waste and flowed beyond the permitted boundary of the site, or . leachate management practices result in nuisances, vector problems, or contact of leachate with humans. An Area of Concern will exist if: . liquid that has percolated through waste is observed flowing or ponding on fill slopes, but is not migrating beyond the permitted site boundary (in such cases, other standards may apply, e.g., grading), or . during the perimeter walk, the inspector has reason to suspect that surface water leaving the site boundary is contaminated due to its appearance, odor or location, or . required leachate monitoring, control and/or treatment systems are determined to be deficient http://www.ciwmb.ca.gov/pe/advisory/20/attach2O/20attch l.htm 8/11/98
