Niagara River Remedial Action Plan Stage 2 Update Report

Niagara River Remedial Action Plan Stage 2 Update Report

(3) Public Advisory

(3) Public Advisory Committee - comprised of various organizations and citizens to effectively involve the community in this review of the Stage 2 RAP (see Appendices 3 and 11). The results of the technical reviews were presented to the Steering Committee as recommendations and suggested new delisting criteria. This work was then compiled in the Technical Review 2007 document 88 for presentation to, and input from, the PAC. In 2008, the Niagara River RAP Coordinating Committee wrote a report to provide an explanation of how the new Niagara River AOC delisting criteria were adapted from the suggested criteria in the Technical Review 2007 (see Appendix 12). From this review several modifications were made to the suggested delisting criteria. These modifications were due to the significant progress that had been made towards refining delisting criteria, as well as further progress made on implementation actions in the Niagara River AOC. In March 2009, the new delisting criteria were presented to the RAP Science Committee and the PAC for discussion and endorsement. 3.3 New Delisting Criteria The refinement of the delisting criteria is intended to lead to a more efficient and effective implementation of remedial action, and better monitoring. Knowing specifically what will bring the AOC closer to delisting, through an improved set of delisting criteria, will help to better screen and prioritize remedial projects. This approach is consistent with what is being done in other Canadian AOCs. The table below shows the new delisting criteria for the Niagara River AOC. Note: Delisting criteria for Eutrophication and Undesirable Algae could not be developed due to lack of information about the Welland River ecosystem. Additional assessment studies have been recommended by the reviewers in order to develop delisting criteria. 88 The Niagara River (Ontario) Remedial Action Plan Team. April 12, 2006.

Niagara river remedial action plan stage 2 update Table 11: Updated Niagara River (Ontario) AOC delisting criteria. Under the status changed column “X” signifies that the delisting criteria has been met under current conditions and a blank cell signifies that it has not yet been met Beneficial Use Impairment 1) Restrictions on Fish and Wildlife Consumption Typically broken into two sections when assessed: }} Fish Consumption }} Wildlife Consumption New Delisting Cirteria 1. No restrictions on the consumption of sport fish in the Ontario portion of the AOC due to locally-controllable contaminant (PCBs and dioxin-like PCBs) sources. The probable sources of contaminants causing the restrictions will be considered; locally-controllable contaminant sources will be addressed by the Niagara River RAP. Any regional or upstream sources that are likely the cause of remaining restrictions on sport fish consumption in the AOC will be identified and referred to a broader regional program (i.e., Lake Ontario Lakewide Management Plan, Lake Erie Lakewide Management Plan and Niagara River Toxic Management Plan). Restrictions on sport fish consumption in the AOC will be evaluated through comparison to restrictions present in appropriate fish species from a suitable non-AOC reference site or sites. 2. 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 consumption, then a risk based Contaminated Sediment Management Strategy must be in place with appropriate monitoring and mitigation measures and/or administrative controls. (Note: A delisting criteria was never developed as this BUI component was never shown to be Impaired only Requiring Further Analysis.) Status Impaired Not Impaired Status Change X 2) Tainting of Fish and Wildlife Flavour Not Impaired 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., Blackcrowned Night-Herons, Herring and/or Ring-billed Gulls).
