This Act is P.L. 92-583 (October 27, 1972) which created the Coastal Zone Management programme in 1972 to provide grants to eligible states and territories as an incentive to prepare and implement plans guiding the use of coastal lands and resources. Amendments in 1990 require participants to develop nonpoint pollution programs. These programmes must specify and implement management measures to restore and protect coastal waters. For agriculture, 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. Federal approval of state proposals is pending.
