EPA Oversight of Watershed Implementation Plans (WIPs) and Milestones in the Chesapeake Bay Watershed
The TMDL is being implemented using an accountability framework that guides restoration efforts using four elements. These elements include Watershed Implementation Plans (WIPs), two-year milestones, EPA’s tracking and assessment of restoration progress and, as necessary, specific federal actions if the Bay states do not meet their commitments. Bay states include Delaware, Maryland, New York, Pennsylvania, Virginia, West Virginia and the District of Columbia.
Under the accountability framework, EPA committed to conduct ongoing oversight of Bay states' programs to ensure they are on track to meet the goals of their WIPs and two-year milestones.
EPA Evaluation of New York’s Amended Phase III WIP -EPA received and evaluated a draft amended Phase III Watershed Implementation Plan (WIP) from New York to meet the 2025 nitrogen target.
EPA assesses milestone progress and future commitments– EPA provided its final evaluations of progress toward meeting the 2018-2019 milestones and of the 2020-2021 milestone commitments to the seven Chesapeake Bay states and the federal agencies. The Chesapeake Bay Program partnership committed to have all practices and controls in place by 2025 to achieve applicable water quality standards for dissolved oxygen, water clarity/submerged aquatic vegetation and chlorophyll-a. Since 2012, the seven states and the federal agencies have established short-term goals, called two-year milestones, to help achieve the 2025 goal.

EPA's goal is for the Bay jurisdictions to successfully implement their Watershed Implementation Plans (WIPs) and two-year milestones to achieve the necessary nutrient and sediment reductions. However, EPA is prepared to take federal actions if it is necessary and appropriate to do so to help the jurisdictions reach their targets. Federal actions can be taken at any time. Potential actions could include:
- Expand National Pollutant Discharge Elimination System (NPDES) permit coverage to unregulated sources.
- Expand EPA oversight review of state-issued NPDES permits and EPA objection to inadequate permits.
- Require net improvement offsets for new or increasing loadings.
- Establish finer-scale waste load allocations and load allocations in the Chesapeake Bay TMDL.
- Require additional reductions of loadings from point sources.
- Increase and target federal enforcement and compliance assurance, including both air and water sources of nitrogen, phosphorus and sediment.
- Condition or redirect EPA grants.
- Federally promulgate local nutrient water quality standards (WQS).
