Supplemental Environmental Projects

The San Diego County Air Pollution Control District (District) administers a Supplemental Environmental Project (SEP) Program to evaluate community-based projects that can be funded from a portion of the penalties received during settlement of enforcement actions. The SEP Program can improve public health, reduce pollution, increase environmental compliance, and bring public awareness to neighborhoods most burdened by environmental harm.  The District’s SEP Program Policy establishes the process for selection of SEPs and how the District will oversee implementation of SEPs that are included in settlement agreements. Eligible SEP proposals must promote public health, pollution prevention and reduction, environmental protection, or environmental compliance and must go beyond any federal, state, and local requirements.

Higher consideration will be given to projects within or that benefit disadvantaged communities. The District uses the CalEnviroScreen as a benchmark to define what communities in San Diego are located within the boundaries of a disadvantaged community. A community's score of 75 percent or greater is defined as a community disproportionality affected by pollution.
