The Administrator and the Under Secretary shall periodically review the guidelines and protocols issued under this subsection to evaluate their effectiveness, the degree to which they continue to answer program objectives and provide an appropriate degree of uniformity while taking local conditions into account, and any need to modify or supplement them with new guidelines and protocols, as needed.
The Administrator or a State permitting authority shall ensure that compliance monitoring conducted pursuant to section 402(a)(2) of the Federal Water Pollution Control Act (33 U.S.C. 1342(a)(2)) for permits for discharges to coastal waters is consistent with the guidelines issued under this subsection. Any modifications of discharge permits necessary to implement this subsection shall be deemed to be minor modifications of such permit. Nothing in this subsection requires dischargers to conduct monitoring other than compliance monitoring pursuant to permits under section 402(a)(2) of the Federal Water Pollution Control Act (33 U.S.C. 1342(a)(2)).
In addition to the criteria listed in paragraph (4), the intensive monitoring program for Massachusetts and Cape Cod Bays shall establish baseline data on environmental phenomena (such as quantity of bacteria and quality of indigenous species, and swimmability) and determine the ecological impacts resulting from major point source discharges.
Prior to implementing any intensive coastal water quality monitoring program under this subsection, the Administrator and the Under Secretary shall enter into a Memorandum of Understanding to implement the intensive coastal water quality monitoring programs and may extend the memorandum  of Understanding to include other appropriate Federal agencies. The Memorandum of Understanding shall identify the monitoring and reporting responsibilities of each agency and shall encourage the coordination of monitoring activities.
The Administrator and the Under Secretary shall consult with the National Academy of Sciences, the Director of the United States Fish and Wildlife Service, the Director of the Minerals Management Service, the Commandant of the Coast Guard, the Secretary of the Navy, the Secretary of Agriculture, the heads of any other relevant Federal or regional agencies, and the Governors of coastal States in developing the Strategy.
Within 1 year after submission of the Strategy under paragraph (1), the Administrator and the Under Secretary shall enter into a Memorandum of Understanding with appropriate Federal agencies necessary to effect the coordination of Federal coastal monitoring programs. The Memorandum of Understanding shall identify the monitoring and reporting responsibilities of each agency and shall encourage the coordination of monitoring activities where possible.
