Historically, wastes stored at these sites have been broadly classified as PCB wastes. In an effort to better manage these sites and in some cases to decommission and close these sites, there is a need for re-evaluation ofthe wastes, propercharacterization (with representative sampling and testing) and permanent disposal ofPCB wastes and non-hazardous wastes. The objective ofthis document is to provide standard procedures for sampling and testing (laboratory analysis) ofcontaminated materials stored at these PCB Storage Sites. The protocol can also be used for the decommissioning ofthese sites or for the clean up ofother PCB contaminated sites. Alternative procedures for sampling can be used for unusual situations, provided that the alternatives have been presented in writing to the Ontario Ministry ofthe Environment (MOE), and the document reviewed and accepted by MOE. Reference analytical methods are suggested but not required forthe analysis or testing ofthe samples. Wastes found at these sites are usually stored either in drums or accumulated in piles or in large containers. The protocol provides detailed procedures for sampling and testing for both methods ofstorage. Sampling and testing ofPCB contaminated materials in piles requires segregation of the various types ofmaterials, representative sampling ofthe segregated piles and statistical analysis ofthe results. Various types ofmaterials are stored in these drums or piles. Detailed procedures for sampling are identified for various type ofmaterials, including soil, rocks, concrete/asphalt, wood, electrical cables, liquid sludge materials, light ballasts and capacitors. This protocol does not include however standards for the classification and management ofPCB contaminated transformers, which are covered under the "PCB Transformer Decontamination Standards and Protocols" (CCME, 1995). Site decommissioning also requires proper sampling and testing ofcleaned surfaces inside buildings and cleaned land on the property. Methods for sampling at decommissioned sites are presented in the last chapter ofthis protocol.
