When enforcement officers inspected a dry cleaner, they found six 10-litre barrels containing PERC residue, which had been in storage for three years. Samples from each barrel confirmed that all six contained PERC at concentrations ranging from 24,600 parts per million (ppm) to 503,000 ppm. Under the PERC regulations, the owner or operator of a dry cleaner must have all of its PERC residue transported to a waste management facility no less than once every 12 months. The dry cleaner and its owner were each ordered to pay $5,000 to the Environmental Damages Fund after pleading guilty to one offence each under the CEPA 1999 [Executive Cleaners and Donald Pattison, Govt.
