Fact Sheet, Agreement and Outcome

The U.S. Environmental Protection Agency (EPA) provided expectations for the Phase I and Phase II Watershed Implementation Plans (WIPs) in 2009 and 2011, respectively, for the seven Chesapeake Bay watershed jurisdictions to demonstrate reasonable assurance that those allocations assigned to the jurisdictions would be achieved and maintained, and that the 2017 targets would be achieved. Through signing the 2014 Chesapeake Bay Watershed Agreement, the jurisdictions reaffirmed their commitment to achieving these goals by 2025. In recent discussions, the jurisdictions remain committed to the 2025 goal.

EPA is now providing expectations for the jurisdictions’ Phase III WIPs to maintain accountability in the work under the 2010 Chesapeake Bay Total Maximum Daily Load (Bay TMDL), encourage continued adaptive management to the new information generated during and after the Bay TMDL 2017 midpoint assessment, and lay the groundwork for implementation of the next generation of innovative practices. In addition, the Principals’ Staff Committee (PSC) established expectations for how to account for changed conditions due to Conowingo Dam infill, climate, and growth. These expectations are directed toward ensuring that the seven jurisdictions, and their local, regional, and federal partners have all practices in place by 2025 that will achieve the Bay’s dissolved oxygen, water clarity/submerged aquatic vegetation, and chlorophyll-a standards.
