Riepilogo

Environmental Protection Agency (EPA) is re-issuing a general permit under the Marine Protection, Research, and Sanctuaries Act (MPRSA) authorizing the National Science Foundation (NSF) to dispose of ice piers in ocean waters. The permit conditions are substantively the same as those established in the permit issued on April 22, 2014. Permit re-issuance is necessary because the current permit has expired.
