AOCs are severely degraded geographic areas within the Great Lakes Basin and are defined by the U.S.-Canada Great Lakes Water Quality Agreement (GLWQA) as "geographic areas that fail to meet the general or specific objectives of the agreement where such failure has caused or is likely to cause impairment of beneficial use of the area's ability to support aquatic life" (GLIN 2005). An impaired beneficial use (IBU) is defined as a change in the chemical, physical or biological integrity of the Great Lakes system that is sufficient to cause any of the fourteen scenarios listed in Table 1. Table 1. Summary of Impaired Beneficial Uses, as defined by the Great Lakes Water Quality Agreement, for the Bay of Quinte Area of Concern. Bay of Impaired Beneficial Use Quinte 9 1. Restrictions on fish and wildlife consumption x 2. Tainting of fish and wildlife flavour 9 3.1 Degradation of fish populations x 3.2 Degradation of wildlife populations ? 4. Fish tumours or other deformities x 5. Bird or animal deformities or reproduction problems 9 6. Degradation of benthos 9 7. Restrictions on dredging activities 9 8. Eutrophication or undesirable algae 9 9. Restrictions on drinking water consumption, or taste and odour problems 9 10. Beach closings 9 11. Degradation of aesthetics x 12. Added costs to agriculture or industry 9 13. Degradation of phytoplankton and zooplankton populations 9 14.1 Loss of fish habitat 9 14.2 Loss of wildlife habitat 9 - identified as an IBU for the Bay of Quinte AOC x - not identified as an IBU for the Bay of Quinte AOC ? - undergoing further evaluation The GLWQA directs the Canadian and American federal governments to cooperate with state and provincial governments to develop and implement Remedial Action Plans (RAPs) for each AOC to restore and protect the impaired beneficial uses within their area (GLIN 2005). Remedial Action Plans identify specific problems in an AOC and provide recommended actions for correcting them. As outlined in Annex 2 of the GLWQA, each RAP should take an ecosystem approach to restoring and protecting beneficial uses in AOCs. Ten IBUs were identified for the Bay of Quinte AOC in the 1990 BQRAP Stage I document, Environmental Setting and Problem Definition (see Table 1). The IBU related to fish tumours is still being investigated to determine if it applies to the Bay of Quinte. Section 1: Introduction 1 One of the IBU’s identified was the loss of fish habitat (IBU #14.1). Given
