The Cuyahoga River Area of Concern (AOC)

formerly Cuyahoga River Remedial Action Plan (RAP)

Bringing 1 river, 21 subwatersheds, and 10 miles of Lake Erie shore back to health

The Cuyahoga River is one of 43 Great Lakes Areas of Concern (AOC) – waters in the the U.S. and Canada that have experienced environmental degradation, fail to meet the objectives of the U.S.- Canada Great Lakes Water Quality Agreement (GLWQA,) and are impaired in their ability to support aquatic life or beneficial uses.

The GLWQA required that each of the Areas of Concern develop a Remedial Action Plan (RAP) to identify the Beneficial Use Impairments (BUIs) and their causes, develop criteria for restoration, implement remedial measures, monitor the effectiveness of such measures, and confirm that restoration is achieved.

The Cuyahoga River has 10 Beneficial Use Impairments, one of which is a locally-identified impairment for lack of public access. (See the list at "The Plan and Targets.")

OhioEPA is the state agency in charge of AOC delisting.
Each AOC has a local stakeholder committee. The Cuyahoga AOC Advisory Committee serves that purpose. The committee includes dozens of stakeholders – agencies, park systems, watershed stewardship groups, businesses, etc) who developed the Delisting Action Plan and are currently involved in implementing the plan.

The Cuyahoga River Area of Concern (AOC)

The lower 46.5 miles of the Cuyahoga River, including all the tributaries that drain to that section of river, and the adjacent Lake Erie shoreline and its tributaries, comprise the Cuyahoga River Area of Concern. The AOC begins at the head of the Gorge Dam pool in Akron/Cuyahoga Falls, ends at Lake Erie, and includes the shoreline from the western Cleveland border to Euclid Creek on the east.
