The requirements for intergovernmental cooperation and public participation continue after program approval.(c) This subpart deals with requirements for coordination with governmental entities, interest groups and the general public to assure that their interests are fully expressed and considered during the program development process and that procedures are created to insure continued consideration of their views during program implementation.
