ISWG

About ISWG

ISWG (pronounced izzy-wig) is a coalition of 14 municipalities in the greater Portland and Saco areas (Biddeford, Cape Elizabeth, Cumberland, Falmouth, Freeport, Gorham, Old Orchard Beach, Portland, Saco, Scarborough, South Portland, Westbrook, Windham, and Yarmouth) that work collaboratively to implement Clean Water Act permit(s). The permit aims to reduce the impact of stormwater pollution on local waterways. In Maine, the Department of Environmental Protection administers this permit on behalf of the US Environmental Protection Agency.

The Cumberland County Soil and Water Conservation District (CCSWCD) coordinates ISWG and provides regional support and implementation of many of the permit’s six required minimum control measures (MCMs).
