EPA has undertaken a self-evaluation of its efforts, under the Pollution Prevention Act (P2 Act) of 1990, to integrate pollution prevention policy into its environmental programs, including air, water, toxics and hazardous waste. This evaluation also looked at the Agency's efforts to promote pollution prevention approaches at other Federal agencies, which is also authorized by the P2 Act. The P2 Act established a national policy that pollution should be prevented or reduced at the source whenever feasible. The P2 Act also directs EPA to consider the effects of its existing and proposed programs on source reduction, and to promote source reduction practices at other federal agencies.
