The Chesapeake Clean Water Blueprint is a collaborative effort between federal and state governments that includes the Chesapeake Bay TMDL—the Environmental Protection Agency's (EPA) established pollution limits for nitrogen, phosphorus, and sediment—and the state Watershed Implementation Plans.
Maryland and the other six Bay jurisdictions agreed to create state-specific roadmaps for how they will meet the pollution reduction requirements laid out in the TMDL by 2025. These roadmaps are called Watershed Implementation Plans or WIPs and give state, township, county, and local jurisdictions the power to cooperatively define the strategies that will be most effective for cleaning up their local waterways and achieving the TMDL.
The WIPs consist of three phases. This year, the Bay jurisdictions are introducing their Phase III WIPs, which will define the final commitments and controls necessary to fully achieve their 2025 pollution reduction targets. EPA is encouraging jurisdictions to include more local engagement strategies in their Phase III WIPs, a strategy that is crucial, as much of the implementation occurs at the local level.

Nitrogen: According to the Maryland Department of the Environment, if the reductions associated with the recent upgrade to the Back River sewage treatment plant, the largest plant in Maryland, were included, the overall 2017 nitrogen reduction goal would have been met.
