Water Quality

Many parts of the Chesapeake Bay contain excess nitrogen, phosphorus and sediment, and are listed as impaired under the Clean Water Act. As part of the Chesapeake Bay Watershed Agreement, the Chesapeake Bay Program has adopted a goal to reduce pollutants to achieve the water quality necessary to support aquatic living resources and protect human health. Under this goal, our partners have adopted two outcomes:

  • 2017 and 2025 Watershed Implementation Plans (WIPs) Outcome: By 2017, have practices and controls in place that are expected to achieve 60 percent of the nutrient and sediment load reductions necessary to achieve applicable water quality standards compared to 2009 levels. By 2025, have all practices and controls in place to achieve applicable water quality (i.e., dissolved oxygen, water clarity/submerged aquatic vegetation and chlorophyll a) standards as articulated in the Chesapeake Bay Total Maximum Daily Load (Bay TMDL).
  • Water Quality Standards Attainment and Monitoring Outcome: Continually improve our capacity to monitor and assess the effects of the management actions being taken to implement the Chesapeake Bay Total Maximum Daily Load (Bay TMDL) and improve water quality. Use monitoring results to report annual progress being made in attaining water quality standards and trends in reducing nutrients and sediment in the watershed.

Track our progress toward these outcomes on ChesapeakeProgress, or through our TMDL tracker, Two-Year Milestone progress tool or Best Management Practice review table.

 

 

Best Management Practice Review

The Chesapeake Bay jurisdictions implement Best Management Practices (BMPs) to achieve the goals set forth in the 2010 TMDL. Through the Protocol for Development, Review and Approval of Loading and Effectiveness Estimates for Nutrient and Sediment Controls, newer practices and technologies are considered and evaluated for inclusion in the Chesapeake Bay Program partnership modeling tools. Existing practices are re-evaluated to ensure they reflect the best available scientific data and information. Below is a table depicting the BMPs identified for review and the status of those reviews.

Additionally, information is now available on receiving nutrient reduction credit for verifiable homeowner BMPs in Chesapeake Bay Program partnership modeling tools.

The Management Board agreed that the Tier I nitrogen and phosphorus efficiencies and the Tier II and Tier III nitrogen efficiencies stand. They additionally approved the Tier II efficiencies for phosphorus and agreed that acres being credited for Tier II phosphorus are conditional on the pending Nutrient Management Taskforce's cross-walk and on the states providing adequate compliance documentation for Tier II phosphorus.

The Nutrient Management Task Force will soon meet to discuss and develop a cross walk template between the state's nutrient management programs and the tiered definitions, as well as compliance documentation for Tier II phosphorus. This Task Force will work closely with the jurisdictions, the AgWG, and WQGIT on both developing and completing this cross walk.
