The Regional Administrator of the Environmental Protection Agency's (EPA) New England Regional Office is providing notice of a final residual designation determination made on October 28, 2009 in accordance with Section 402(p) of the Clean Water Act, and implementing regulations in 40 CFR 122.26(a)(9)(i)(D). The final determination requires that storm water discharges from impervious areas equal to or greater than one acre in the Long Creek watershed (South Portland, Westbrook, Scarborough, and Portland, Maine) be authorized by a permit under the federal Clean Water Act because those discharges contribute to a violation of water quality standards in Long Creek. Copies of the final residual designation and other materials are available for inspection online as described elsewhere in this notice document.
