New federal regulations to reduce the use and release of toxic substances into the environment

The Government of Canada today announced new
regulations that will significantly reduce future contamination of our air and
water from two toxic substances used in manufacturing processes across Canada.
The regulations, under the Canadian Environmental Protection Act (CEPA), will
bring about a 65% reduction in the use of trichloroethylene (TCE) and
tetrachloroethylene (PERC) in substances used in solvent degreasing
operations.
