This May 2010 guidance presents the most effective tools and practices to address nonpoint source pollution from federal land management activity in the Chesapeake Bay watershed. This guidance covers the following categories: agriculture, urban and suburban (including turf), forestry, riparian areas, decentralized wastewater treatment systems, and hydromodification. 

The guidance, a requirement of Section 502 of the President's Chesapeake Bay Executive Order 13508, provides federal land managers with a guide to implementing the best proven tools and practices to restore and protect the region's waterways and the Bay. The same techniques can be utilized by states, local governments, conservation districts, watershed organizations, developers, farmers and citizens in the Chesapeake Bay watershed.
