Great Lakes AOCs

Restoring Ashtabula River AOC (timeline)

Year Critical Actions

Three Beneficial Use Impairments removed:

  • Restrictions on fish and wildlife consumption
  • Degradation of fish and wildlife populations
  • Loss of fish and wildlife habitat.

Strategic Navigation Channel dredging. 158,000 cubic yards dredged from the navigation channel to ensure future navigation activities.

The Ashtabula North Slip Great Lakes Legacy Act project was completed. 11,000 cubic yards were dredged to address the final pokcet of contamination in the AOC.


1,500 linear feet of fish shelves and plantings are created using funds from the Great Lakes Restoration Initiative at the 5 ½ slip.


The 5 ½ Slip project begins. The first phase is done under the Great Lakes Legacy Act at the northern end of the slip. Expected outcomes include remediated wetlands, thousands of feet of fish shelves, improved fish and wildlife habitat, improved oxygen levels and better flow rates.


Ohio EPA published delisting targets for the Ohio Areas of Concern.

A post-dredging habitat enhancement report was published that detailed potential future restoration plans. Land preservation and human recreation efforts were also considered in the report.



A Great Lakes Legacy Act cleanup was completed at the cost of approximately $60 million. Over 500,000 cubic yards of contaminated sediment was removed including 25,000 pounds of PCBs and other hazardous materials. Human health and ecological risks were reduced as a result.


Remediation activities at the Fields Brook Superfund site were completed. Monitoring will minimize future contamination in the AOC.


A comprehensive management plan for the river was issued that includes analyses from an investigative and feasibility study, an environmental impact statement, remedy selection and community support.


The first remedial action plan was published by Ohio EPA.
