The Pollution Prevention Information Network (PPIN) grant program funds regional centers that serve both regional and national pollution prevention (P2) information needs. Grantees determine audience needs and then supply quality information and training on source reduction and related P2 practices. Grantees provide assistance and training to businesses whose lack of information may be an impediment to implementing source reduction, preventing pollution or adopting sustainable practices. Grantee activities must support regional P2 priorities and the national P2 information network. Proposals must describe P2 outputs and projected P2 outcomes for all activities. The work plan must describe how progress towards achieving the expected environmental outcomes will be measured.
