Centroid point locations of ocean disposal sites designated under the MPRSA.  

 

The EPA designates and manages ocean sites for certain materials permitted under the MPRSA.  Locations for designated MPRSA ocean sites are selected to minimize the risk of potentially adverse impacts of the disposed material on human health and the marine environment.  

 

Designated ocean sites are published in the Code of Federal Regulations at 40 CFR 228.15. As of October 2024, the EPA’s Marine Protection Permitting Program manages 99 designated MPRSA ocean sites. The number of ocean sites may vary slightly from year to year as the EPA designates a new site or cancels (de-designates) a site that is no longer needed. All but one of the currently designated ocean sites are for dredged material permitted or authorized under the MPRSA. There is currently one EPA-designated ocean site for the disposal of fish processing wastes off American Samoa.
