EPA
 and  Canada

 The  United States and  Canada  share a 5,100-mile
 border across which air and water pollution flow.  Both
 countries are concerned with control of this pollution,
 as well as with protection of shared  natural resources,
 such as the Great  Lakes. EPA is deeply involved in
 negotiations between the two countries on transboun-
 dary pollution problems, and plays a major role in  im-
 plementation of the Great  Lakes Water Quality Agree-
 ment, which the United States and  Canada signed in
 1972 and renewed in 1978. In  addition, the extensive
 trade  relations  between  the  two  countries  require
 cooperation to minimize potential hazards in the inter-
 national movement of toxic chemicals.
   A major forum for resolving transboundary pollution
 problems is the International Joint Commission,  estab-
 lished by the Boundary Waters Treaty of 1909. Through
 the IJC—made up of threeUnited States  and three Cana-
 dian representatives—the two countries are developing
 solutions to such problems as pollution  of U.S. air and
 water by Canadian power development projects, and
 threatened  pollution of Canadian waters by the pro-
 posed Garrison Diversion Project in North Dakota. EPA
 plays an advisory role in formulating IJC-recommended
 solutions to these problems.
   An important IJC concern is pollution of the Great
 Lakes, which contain 20 percent  of  the world's fresh
 water supply. Phosphorus introduced  into the  lakes
 has caused  excessive  organic growth,  resulting  in
 eutrofication. Drinking water supplies, fisheries, and
 other uses of Lake waters have been threatened by such
 toxic substances as pesticides, heavy  metals, and poly-
 chlorinated biphenyls (PCBs). The two nations, with ex-
 tensive  technical assistance from EPA, are  trying  to
 reverse the  deterioration of the Lakes.  The quality of
 Great  Lakes  waters  is  gradually  being  restored,
 although serious problems remain, particularly in Lakes
 Ontario and Erie.
   EPA is represented on the U.S. Canadian Consulta-
 tive Group on Long Range Transport  of Air Pollutants.
 This group was formed in 1978 to coordinate research
 on this issue. A particular concern is acid rain, which is
 seriously threatening forests and lakes in Ontario Prov-
 ince and the northeastern United States. The primary
 cause of acid rain is burning of sulfurous fuels, such as
 coal.
   EPA is actively engaged in Congressionally-mandated
negotiations with Canada seeking an air pollution agree-
ment under which transboundary air pollution problems
 can be resolved. These negotiations were initiated  in
 December, 1978.
   Some of the other areas in which EPA and Canada
 are working together include:

 •  Cooperation on the regulation of toxic chemicals, and
 harmonization of criteria,  testing and evaluation pro-
 cedures.

 •  Development of compatible regulations for toxic and
 hazardous waste disposal.

 •  Development of joint contingency plans to clean up
 oil spills in the Great Lakes and coastal waters.

 •  Regular exchanges of research data  concerning air
and water pollution.

• Cooperation and consultation on positions taken in
international forums.
