The Environmental Protection Agency (EPA) has released draft guidance on ways of reducing nonpoint source pollution from farms, lawns, septic systems, and other sources across the Chesapeake Bay watershed. The guidance provides detailed recommendations and cost estimates for bayprotection activities that would reduce the risk of pollution from agriculture, urban and suburban development and septic tanks, and protect forestry, riverbanks and stream banks. The guidance urges that development and redevelopment projects maintain the land’s hydrology to the “maximum extent technically feasible” and presents background information and examples that demonstrate how to implement low-impact development and other green infrastructure techniques.
