The Supplemental Environmental Projects (SEP) Database is a web application that contains information on historic and available environmental improvement proposals that have been reviewed and approved by DEQ Enforcement. A SEP is an environmentally beneficial project that a defendant/respondent agrees to undertake in partial settlement of a civil penalty action.The SEP Database connects environmental improvement project ideas with parties seeking to offset civil penalties through meaningful environmental action. Supplemental Environmental Projects, or SEPs, redirect penalty resources toward immediate environmental benefits—creating transparency, consistency, and tangible improvements for Virginia's communities and ecosystems.
