Historical sites
where PCBs were handled and stored.
Often in the past, before Swan Hills, Alberta, was open to PCB imports, owners stored PCB equip ment on their site. The MOE assigned a PCB site number and required the generator to register their PCB wastes. From that point on, an owner was in
Any rooms, substations or contain ers previously used for storage of PCBs must be wipe-tested for PCB residues. When floors or storage con tainers appear to be clean on visual inspection, wipe samples are taken without pre-cleaning. The PCB residues must be < 10 ug/100 cm sq or

wipe samples are taken. Where shipping containers are involved for storing PCB wastes out side, as opposed to inside of a build ing, samples of soil are taken from around the perimeter of the container and are submitted to the lab for direct
PCB analysis on each separate sample. In addition, based on site character istics, a modified leachate test is per formed on a composite of all soil sam ples taken to target other chlorinated hydrocarbons, heavy metals, PAHs, pesticides, etc., as the situation may dictate.
It must be kept in mind that even the most rigorous sampling and analy sis exercises cannot give the whole site a clean bill of health. It is not uncom
mon to find companies that are not aware that they still have PCBs in light ballasts, underground storage tanks, potheads, cables, compressors, electro magnets, rectifiers, circuit breakers,

receiving facility within 30 days to avoid having to re-register the site and go through the whole "decoimnissioning" process again. In these cases concerning PCBs, ignorance is not bliss. Before breaking out the champagne and celebrating your "freedom" from PCBs, it would be advisable to conduct a comprehen sive survey, preferably by a PCB spe cialist. Dr.
