Beneficial Use Impairments (BUIs)

Beneficial Use Impairments (BUIs) are any biological or economical uses of the natural resource that has been negatively impacted by environmental degradation. The Great Lakes Water Quality Agreement (GLWQA) outlines 14 BUIs as the criteria for listing AOCs.

The current status of each BUI is listed below:

Status - Southern AOCStatus - Northern AOC
1. Restrictions on Fish and Wildlife ConsumptionImpairedImpaired
2. Tainting of Fish and Wildlife FlavorNot impairedNot impaired
3. Degradation of Fish and Wildlife PopulationsImpaired Impaired
4. Fish Tumors or Other DeformitiesImpaired Requires further assessment
5. Bird or Other Animal Deformities or Reproductive ProblemsImpairedNot impaired
6. Degradation of BenthosImpaired Not impaired
7. Restriction on Dredging ActivitiesNot impairedNot impaired
8. Eutrophication of Undesirable AlgaeNot impairedImpaired
9. Restriction on Drinking Water or Taste and Odor ProblemsNot impaired
10. Beach ClosingsNot impairedImpaired
11. Degradation of AestheticsNot impairedNot impaired
13. Added costs to Agriculture or IndustryNot impairedNot impaired
13. Degradation of Phytoplankton and Zooplankton Populations RemovedRequires further assessment
14. Loss of Fish and Wildlife HabitatImpairedImpaired

The goal of the Remedial Action Plan (RAP) will be reached when none of these impairments exist.

The St. Lawrence River AOC Program at the Saint Regis Mohawk Tribe (SRMT) was developed in October 2010 from a competitive funding award from U.S. Environmental Protection Agency (EPA) Great Lakes National Program Office (GLNPO) Grant GL-9722130-10. SRMT has been working diligently to make advancements on delisting targets and updating BUI statuses in the St. Lawrence River AOC, under this funding source.

On-going projects under Grant GL-9722130-10 were developed to address the six impaired BUIs listed above.
