Appendix 2

Canada Ontario Agreement respecting the Great Lakes Basin Ecosystem

The Tier 1 listing includes the 11 critical pollutants identified by the International Joint Commission, plus critical pollutants identified in the Niagara River and Lake Ontario Toxic Management Plans and the Lake Superior Binational Program. Tier 1 pollutants are targeted for virtual elimination by adopting the philosophy of zero discharge for local or direct sources, and by encouraging similar actions binationally and globally in order to eliminate distant sources or long-range transport as inputs to the Great Lakes Basin.

Aldrin/dieldrin

Benzo(a)pyrene

Chlordane

DDT

Hexachlorobenzene

Alkyl-lead

Mercury

Mirex

Octachlorostyrene

PCBs

PCCD (dioxins)

PCDF (furans)

Toxaphene

 

Tier II compounds include substances identified by science-based screening methodologies or Lakewide Management Plans. These substances have the potential for causing widespread impacts, or have already caused local adverse impacts on the Great Lakes environment.

Anthracene

Cadmium

1,4-dichlorobenzene

3,3'-dichlorobenzidine

Dinitropyrene

Hexachlorocyclohexane

4,4'-methylenebis(2-chloraniline)

Pentachlorophenol

Tributyl tin

Plus 17 PAH's as a group, including but not limited to:

Benz(a)anthracene

Benzo(b)fluoranthene

Benzo(g,h,i)perylene

Perylene

Phenanthrene

Tier II will be updated periodically, on the basis of sound science, to ensure emerging contaminant issues are addressed as information becomes available. Persistent, bioaccumulative and toxic substances may be elevated from the Tier II listing through a weight-of-evidence approach, and through a process of stakeholder consultation.
