EPA is issuing this RFA to support the Chesapeake Bay Program (CBP) partnership's continuing mission of evaluating the effectiveness of implemented and proposed management actions taken to reduce nutrient and sediment pollutant loads and to improve Chesapeake Bay water quality through the seven watershed jurisdictions' WIPs under current and future climate change and growth. The CBP's mission includes enhancing and maintaining the accountability of systems dependent on tracking, verifying, reporting, and quantifying the estimated pollutant load reduction potential of practices, treatments, and technologies implemented throughout the watershed and assessing their collective influence on Chesapeake Bay tidal water quality.
