The Environmental Protection Agency approved new rules today that will quadruple the amount of some toxic pollutants that companies can release before they have to reveal the amounts to the public.

Federal officials originally proposed a 10-fold increase in the trigger for public reports on most chemicals covered by the the 20-year-old “Toxic Release Inventory” program. EPA Deputy Administrator Marcus Peacock said the revised limits will ease regulatory burdens on industry while giving companies an incentive to recycle or better manage toxic compounds.
