Managing Environmental Liability from Dry Cleaner Releases
The management of environmental liability from dry cleaner impacts is a challenging effort for retail properties. The chemical historically used for dry cleaning – tetrachloroethene (often referred to as PCE or “perc”) – is a chlorinated volatile organic compound that has also been used in various industrial operations. Once released, PCE can present long-lasting environmental and human health risks. Replacing dry cleaners that utilize PCE with those using alternative “green” chemicals can prevent future PCE releases, however in many cases the release has already occurred due to years of operations.
