The Department of State delisted the Presque Isle Area of Concern (AOC), located in northwestern Pennsylvania, at the recommendation of the Environmental Protection Agency. Areas of Concern are designated locations that have experienced environmental degradation. The Department of State has jurisdiction over the AOC listings under the Great Lakes Water Quality Agreement, which was recently amended in September 2012. The Presque Isle delisting is only the second in the United States; the State Department also delisted the lower Oswego River in New York. Northeast-Midwest Congressional Coalition Co-Chair Rep. Mike Kelly (PA-03), in whose district the Presque Isle is located, credits "the many conservation, environmental, and sportsman groups in Erie County who have made the health of Presque Isle Bay a community priority" for the delisting. Although delisted, Presque Isle Bay will continue to receive support from the Environmental Protection Agency to monitor ecological conditions.
