[email protected] MBI/CABB Ashtabula, Ohio Post Dredging Habitat Enhancement Plan March 30, 2008 Introduction The lower Ashtabula River has long been an area of environmental concern due to chemical contamination and long use as a deep draft commercial harbor. The lower river, from the 24th St. Bridge to the river mouth including the Lake Erie shoreline immediately east and west of the river mouth, was declared an Area of Concern (AOC) under the 1987 Great Lakes Water Quality Agreement. Documents detailing the status of the Area of Concern (AOC) have been developed by Ohio EPA, the Ashtabula River Partnership, the U.S. Army Corps of Engineers, and others. Most of these documents can be found at U.S. EPA’s Ashtabula River AOC web site at: www.epa.gov/glnpo/aoc/ashtabula.html. A Natural Resource Damage Assessment was conducted under the authority of the Superfund (CERCLA) program to assess injury to natural resources caused by the release of toxic substances.
