3) Degradation of Fish & Wildlife Populations Typically broken into four sections when assessed: }} Degradation of Fish Populations }} Body Burdens of Fish }} Degradation of Wildlife Populations }} Body Burdens of Wildlife 3. Maintenance of fish community populations, on the Canadian side of the Niagara River, at or above suitable non-AOC reference sites OR meets fish community objective(s) identified through a fisheries management plan by Ontario Ministry of Natural Resources. 4. Maintenance of wetland-dwelling wildlife populations and diversity at or above suitable non-AOC reference sites (as determined by indicators such as Indices of Biotic Integrity and/or community status assessments derived from Bird Studies Canada’s Marsh Monitoring Program). 5. Maintenance of colonial nesting birds populations on the Canadian side of the Niagara River at or above suitable non-AOC reference sites, examined through the use of sentinel species (i.e., Black-crowned Night- Herons, Herring and/or Ring-billed Gulls). 6. Temporal trends in contaminant levels (PCBs and dioxin-like PCBs), examined through the use of sentinel species, (i.e., Herring Gull, night-heron, snapping turtle eggs, and/ or livers of mink), are stable or declining. Spatial comparisons show that contaminant concentrations in the eggs of the above species in areas under the influence of the Niagara River (Ontario) AOC are equal to or less than those from sites removed from any influence of the AOC. If the whole body burden concentrations do exceed this level then they must not result in a population level affect to the bird and/or wildlife populations. 7. OR if a contaminated site (as designated by the Niagara River Contaminated Sediment Technical Advisory Group*) fails to meet the criteria described above in regard to fish and wildlife body burdens, then a risk based Contaminated Sediment Management Strategy must be in place with appropriate monitoring and mitigation measures and/or administrative controls.

Niagara river remedial action plan stage 2 update 4) Fish Tumours and Other Deformities 5) Bird or Animal Deformities or Reproduction Problems 6) Degradation of Benthos Typically broken into two sections when assessed: }} Dynamics of Benthic Populations }} Body Burdens of Benthic Populations 7) Restrictions on Dredging Activities (Note: A delisting criteria will be developed if this BUI is shown to be Impaired) 8. When the types and frequency of deformities and/or reproduction impairments associated with contaminant exposure (PCBs and dioxinlike PCBs) are similar to those at a suitable non-AOC reference site or sites, examined through the use of sentinel species (i.e., snapping turtles, herring gulls). If the types and frequency of deformities and/or reproductive impairments exceed this target then they must not result in a population level affect to the bird and/or animal populations. 9. When acute and chronic toxicity, community composition and abundance in the benthic community are similar to non-AOC reference sites. 10. When benthic invertebrate tissue contaminant (PCBs and dioxin-like PCBs) concentrations are comparable in the AOC to those at a suitable non-AOC reference sites for contaminants that biomagnifies in the aquatic food chain and/or in cases where benthic invertebrate tissue contaminant concentrations are greater than reference sites but are below concentrations considered to impair the beneficial uses associated with the consumption of fish and wildlife. 11. OR if a contaminated site (as designated by the Niagara River Contaminated Sediment Technical Advisory Group*) fails to meet the criteria described above in regard to degradation of benthos, then a Contaminated Sediment Management Strategy must be in place including a risk management approach with appropriate monitoring and mitigation measures and/or administrative controls. (Note: Changed to Not Impaired as per the decision on May 4, 1998 by the Canada-Ontario Agreement RAP Steering Committee.)
