Starting in 2009, the Chesapeake Bay Program (CBP) launched a new and aggressive multi-state strategy to reduce the loading of nutrients and sediment to the Bay to increase the pace of restoration. Central to this program are the two-year milestone commitments from each state, which are integral steps toward reaching the newly released Total Maximum Daily Load (TMDL). A National Research Council committee is nearing completion of a 21-month review of the Chesapeake Bay Program’s nutrient reduction program, sponsored by the EPA, with funding support from Maryland, Virginia, Pennsylvania, and the District of Columbia. The report examines the CBP’s two-year milestone strategy and implementation as a means to reach the nutrient and sediment reduction goals. In its report, the committee also evaluates the tracking and accounting efforts that are used to monitor the implementation of best management practices and, thereby, determine the progress toward meeting the CBP goals. The committee evaluates the adaptive management strategies being developed by the CBP and the Bay states and discusses the most appropriate and useful applications for adaptive management in the Chesapeake Bay watershed. Finally, the report discusses improvements to the nutrient reduction strategies to help increase the likelihood of achieving the goals.
