This environmental assessment is prepared pursuant to the National Environmental Policy Act (NEPA), 42 U.S.C. 4321 et seq. to assess the environmental impacts associated with the approval and implementation of the Coastal Nonpoint Pollution Control Program (coastal nonpoint program) submitted to NOAA and EPA by the state of Indiana. Section 6217 of the Coastal Zone Act Reauthorization Amendments (CZARA), 16 U.S.C. 1455b, requires states and territories with coastal zone management programs that have received approval under section 306 of the Coastal Zone Management Act to develop and implement coastal nonpoint programs. For purposes of this environmental assessment, the proposed action is the conditional approval of the Indiana coastal nonpoint program. The Indiana coastal nonpoint program includes the implementation of management measures for agriculture, urban development, marina, and hydromodification nonpoint source categories, and for wetlands, riparian areas, and vegetated treatment systems. The coastal nonpoint program will be implemented in the Indiana 6217 management area, which includes the Little Calumet-Galien watershed.
