results of municipal and industrial waste reduction and detergent 

 phosphorus control programs. 



The United States, in consultation with, affected States, has re- 

 Adewed the reductions in phosphorus loadings to Lakes Superior and 

 Pluron recommended by the International Great Lakes Water Quality- 

 Board, and believes that these recommendations provide a desirable 

 basis for an agreement on reductions in phosphorus loadings to be 

 sought in Lakes Superior and Huron. 



Accordingly, the Department of State proposes that the Govern- 

 ments of the LTnited States and Canada agree to seek to obtain the 

 gross reductions in inputs of phosphorus to Lakes Superior and Huron 

 as listed in the above tables, in implementation of Section 8 of Annex 

 2 of the Great Lakes Water Quality Agreement. 



If the foregoing proposal is acceptable to the Government of 

 Canada, the Department of State proposes that this Note and the 

 Embassy of Canada's reply shall constitute an agreement between the 

 Government of the United States and the Government of Canada. 

 The agreement shall enter into force on the day of the Embassy's 

 reply and shall constitute Appendix I of the Great Lakes Water 

 Quality Agreement.

 November 21, 1973 concerning Section 8 of Annex 2 of the Great 

 Lakes Water Quality Agreement, in wliich Canada and the United 

 States undertook jointly to determine gross reductions in inputs of 

 phosphorus loadings to Lake Superior and Lake Huron. 



The Government of Canada recognizes that this matter has been 

 considered by the International Great Lakes Water Quality Board, 

 and the International Joint Commission, which have recommended. 

 Trending further studies, the adoption of the tables of gross reductions 

 in phosphorus loadings which are contained in the Department of 

 State's Note. 



The Goveinment of Canada agrees that the amounts shown as 

 "residual loads'- iii the tables do not constitute allocations to the two 

 countries but represent anticipated results of municipal and industrial 

 waste reduction and detergent phosphorus control programs. 



The Government of Canada in consultation with the Provincial 

 Governments has reviewed the reductions in phosphorus loadings to 

 j^alffis Superior and Huron recommended by the International Great 

 Lakes Water Quality Board, and the International Joint Commission, 

 and proposed by the Department of State, and agrees that these 

 recommendations provide a desirable basis for an agreement to seek
