In April 2003, the U.S. Environmental Protection Agency (EPA) published the Ambient Water Quality Criteria for Dissolved Oxygen, Water Clarity and Chlorophyll a for the Chesapeake Bay and Its Tidal Tributaries (Regional Criteria Guidance) in cooperation with and on behalf of the six watershed statesNew York, Pennsylvania, Maryland, Delaware, Virginia and West Virginiaand the District of Columbia. At the time of publication of the Regional Criteria Guidance document, a number of technical issues still remained to be worked through, resolved and documented. This first EPA published addendum to the 2003 Ambient Water Quality Criteria for Dissolved Oxygen, Water Clarity and Chlorophyll a for the Chesapeake Bay and Its Tidal Tributaries documents the resolution of and recommendations for addressing a number technical issues and criteria attainment procedures. This document should be viewed by readers as supplemental chapters and appendices to the original published Regional Criteria Guidance document. The publication of future addendums by EPA is likely as continued scientific research and management application reveal new insights and knowledge to be incorporated into revisions of state water quality standards regulations in upcoming triennial reviews.
