The U.S. Army Corps of Engineers, Honolulu Engineer District (USACE) and the U.S. Environmental Protection Agency, Region IX (EPA) have prepared a revised Site Management and Monitoring Plan (SMMP) for the five existing Ocean Dredged Material Disposal Sites (ODMDSs) serving Hawai‘i: South O‘ahu, Hilo, Port Allen, Nawiliwili, and Kahului.
