Chesapeake Bay TMDL

Sector-Specific EPA Oversight in the Chesapeake Bay Watershed

Overview

Under the accountability framework associated with the Chesapeake Bay TMDL, EPA committed to conduct ongoing evaluations of Bay jurisdictions' Watershed Implementation Plans (WIPs) and two-year milestones. In addition to these on-going evaluations, EPA conducts periodic reviews of state programs as part of its oversight responsibilities under the Clean Water Act.  EPA works with the Bay jurisdictions (Delaware, Maryland, New York, Pennsylvania, Virginia, West Virginia and the District of Columbia) to make improvements to these programs. 

EPA's assessments evaluated the jurisdictions' implementation of programs to achieve reductions in the amount of nitrogen, phosphorus, and sediment required in the Chesapeake Bay TMDL.  The assessments looked at the jurisdictions' implementation of federal and state regulatory programs, as well as voluntary incentive-based programs.  EPA is using these assessments, coupled with ongoing WIP and milestone evaluations to ensure the jurisdictions have the programs, policies, and resources necessary to meet the Bay TMDL.

Trading and Offsets

EPA conducts periodic reviews of Bay jurisdiction programs as part of its oversight responsibilities under the Clean Water Act. The Bay jurisdictions include Delaware, Maryland, New York, Pennsylvania, Virginia, West Virginia and the District of Columbia. EPA completed its first review of the jurisdictions' offset and trading programs to meet target load reductions of nitrogen, phosphorus and sediment.

EPA provided drafts of its reviews to the jurisdictions and interested stakeholders in December 2011 and finalized these reports in 2012. Comments were received from interested stakeholders on the draft reports.

EPA continues to work with the jurisdictions to address areas of concern identified in the final reports. EPA has asked each jurisdiction to prepare a Sector Load Growth Demonstration using the Sector Growth Technical Memorandum as a guide.
