bayThe Chesapeake Bay Total Maximum Daily Load (Bay TMDL) is an effort to restore and protect the Chesapeake Bay and all the rivers and streams that feed into it. The Bay TMDL was established in 2010 by the U.S. Environmental Protection Agency and it applies to the District of Columbia, Delaware, Maryland, New York, Pennsylvania, Virginia and West Virginia.

The Bay TMDL is designed to ensure that all actions necessary to fully restore the health of the Bay and its tidal rivers are in place by 2025. By 2017, practices should be in place to meet 60 percent of the overall nitrogen, phosphorus and sediment reductions required to meet the Bay TMDL.

A midpoint assessment “check-in” is taking place in 2017 evaluate what progress has been made, account for new or additional pollution reduction practices, enhance tools with new scientific information and analyses and update pollution targets as needed. This will be used to inform the development of Phase III Watershed Implementation Plans (WIPs), which are states’ guide for meeting nitrogen, phosphorus and sediment pollution reduction targets.

Agriculture is the single, largest source of pollution in the Chesapeake Bay – and therefore must be a major contributor to the Bay cleanup effort. MCAC helps keep track of Maryland’s progress towards meeting its Bay cleanup goals, with a focus on the agricultural sector, and we will be reviewing Maryland’s Phase III WIPs and providing input.
