Approaching the Chesapeake Bay Midpoint Assessment -- Part II

Yesterday in this space, I took a look at the progress that three Chesapeake Bay watershed states – New York, Pennsylvania, and West Virginia – have made in implementing their Watershed Implementation Plans (WIPs), on their way – perhaps – to meeting the Total Maximum Daily Load (TMDL) pollution reduction targets for 2025. In this post, I'll take a look at Delaware, Maryland, Virginia, and Washington, DC.


The Delaware Department of Natural Resources and Environmental Control (DNREC) is leading the WIP implementation effort in the state. The department has convened a Chesapeake Bay Interagency Workgroup made up of representatives from each DNREC Division, the Department of Agriculture, Department of Transportation, Office of State Planning Coordination, County Conservation Districts, and other stakeholders. The workgroup will focus on two selected sectors: agriculture and developed. They are responsible for recommending and reviewing sub-allocating methodologies to the various nonpoint sources within the basins, assessing current data tracking and reporting systems, and determining maximum implementation goals and methods to fill program funding gaps.

Prior to the Phase III WIP development, progress had been made to increase the acreage of forest and grass buffer best management practices, which have played a role in reducing nitrogen and phosphorus from the …

The Chesapeake Bay restoration effort is arguably one of the largest conservation endeavors ever undertaken. The Bay watershed is made up of 150 major rivers and streams and contains 100,000 smaller tributaries spread across Delaware, Maryland, New York, Pennsylvania, Virginia, West Virginia and the District of Columbia. It supplies drinking water for more than 17 million residents and is one of the most important economic drivers on the East Coast of the United States.

The Chesapeake Bay Total Maximum Daily Load (TMDL), enacted in 2010 by the Environmental Protect Agency (EPA) in collaboration with the Chesapeake Bay states, is a framework for allocating and eliminating excessive loads of nitrogen, phosphorus, and sediment polluting the watershed. It was designed to ensure that pollution control measures would reduce persistent dead zones in the Bay and its tidal tributaries by 2025. As part of the TMDL, the states and …
