The Coastal Zone Management Program was created by P.L. 92-583 (October 27, 1972). It provides grants to eligible states and territories as an incentive to prepare and implement plans guiding the use of coastal lands and resources. Thirty-four of the 35 eligible states and territories are implementing federally-approved plans. Amendments in 1990 require participants to develop agricultural nonpoint pollution programs. These programs must specify and implement management measures to restore and protect coastal waters. Management measures are specified for erosion, sediments, nutrients, pesticides, grazing, and animal waste. Participants must implement these management measures after they have been approved by whatever means necessary, including regulation. EPA and NOAA have conditionally approved all these programs; only a few states have received final approval.
