on a calendar year basis, with the report for 1991 being the eleventh in the series. The 

 Committee is also responsible for drawing to the attention of Governments definitive 

 changes in monitored parameters which may require immediate attention. 



A responsibility of the Committee is to review the adequacy of the monitoring programs 

 In both countries and make recommendations to Government on the Technical Monitoring 

 Schedules. The Schedules are updated annually for new and discontinued programs and 

 for modifications in sampling frequencies, parameter lists, and analytical techniques of 

 ongoing programs. The Technical Monitoring Schedules listed in the annual report 

 (Annex 2) are given for the forthcoming year. The Committee will continue to review and 

 propose changes to the Technical Monitoring Schedules as information requirements 

 change. 



Another responsibility of the Committee has included an ongoing quarterly exchange of 

 data acquired through the monitoring programs. The exchange of monitoring information 

 was initiated with the first quarter of 1 981 , and was an expansion of the informal quarterly 

 information exchange program initiated between Canada and the United States in 1976. 

 At the request of the Committee, the two governments approved replacement of the 

 quarterly data exchange by an annual exchange effective at the start of the 1 992 calendar 

 year. Special reports dealing with aspects of monitoring and monitoring results requested 

 by the Committee are sometimes published. Reports reviewed by the Committee during 

 1991 are identified in Annex 3. Exchanged data and reports are available for public 

 viewing at the agencies of the participating governments or from Committee members.
