Areas of Concerns (AOCs)

About AOCs

exit EPA (About PDF)

Forty-three AOCs have been identified: 26 located entirely within the United States; 12 located wholly within Canada; and five that are shared by both countries. RAPs are being developed for each of these AOCs to address impairments to any one of 14 beneficial uses (e.g., restrictions on fish and wildlife consumption, dredging activities, or drinking water consumption) associated with these areas.  USEPA has assigned RAP Liaisons for AOCs.  Sediments have been identified as serious problems in many AOCs. AOC Principles and Guidelines have been finalized for formally delisting these areas as beneficial uses are restored.
