Best Management Practice Review Why evaluate BMPs? Partnership recognized best management practices (BMP) are based on currently available scientific information and best professional judgment at the time of their development. New scientific data may initiate a re-evaluation periodically to adjust associated definitions and effectiveness values. Partnership experiences in tracking, verification and reporting BMP implementation may also initiate a re- evaluation.

Best Management Practice Review Why evaluate BMPs? Similar to when the Tributary Strategies were developed in response to the Chesapeake 2000 agreement goals, implementation of currently approved BMPs may not achieve the goals set forth in the 2010 TMDL without incorporating new management opportunities. In addition to increasing implementation of the existing BMPs, new technologies are constantly arising, supplementing or replacing traditional practices that may have been in place for years.

Best Management Practice Review Why evaluate BMPs? Interim or provisional BMPs that have been proposed by the jurisdictions and approved by the CBPO are available for planning purposes only; e.g. WIPs, Milestones. To allow the reporting of these new interim BMPs for progress towards the 2010 TMDL goals, the interim BMPs must go through the partnership approved evaluation process to be officially recognized.

Best Management Practice Review Through the partnership approved “Protocol for Development, Review and Approval of Loading and Effectiveness Estimates for Nutrient and Sediment Controls”, new and interim BMPs are considered and evaluated for inclusion in the modeling tools, and long-standing BMPs are re- evaluated to be sure they are still properly portrayed. A number of workgroups have identified a listing of priority BMPs that, once incorporated, will improve the modeling tools.
