Ocean Acidification and the Clean Water Act Section 303(d) Program
Ocean acidification awareness is in its infancy, but attention to this issue is increasing in both the public and private sectors. On November 15, 2010, the US Environmental Protection Agency (US EPA) issued a Memorandum to provide information to assist the Regions and States in preparing and reviewing Integrated Reports related to OA impacts under Sections 303(d), 305(b), and 314 of the CWA as part of a settlement agreement with the Center for Biological Diversity. One of the conditions of the agreement was that EPA would sign a Federal Register (FR) notice requesting comment on how to address OA under the CWA 303(d) program. In addition, EPA agreed to issue a Memorandum by November 15, 2010, describing how EPA will proceed with regard to the interplay between OA and the 303(d) program in light of the responses to the FR notice. This paper summarizes these actions, and presents additional information on assessment methods related to OA that could be useful to States as they move forward to address this important issue.
