Another responsibility of the Committee has included an ongoing exchange of data acquired through 

 the monitoring programs. Exchanged data and reports are available for public viewing at the agencies 

 of the participating governments or from Committee members. 



2.4 Data Exchange 



The Committee is responsible for assuring exchange of data between governments. The exchange of 

 monitoring information was initiated in the first quarter of 1981 and was an expansion of the informal 

 quarterly exchange program initiated between the United States and Canada in 1 976. Until 1 991 , data 

 were exchanged on a quarterly basis. At the request of the Committee, the United States and Canada 

 agreed to replace the quarterly exchange of data with an annual exchange effective at the beginning of 

 the 1 992 calendar year. Henceforth, data will be exchanged once each year as soon after the end of the 

 calendar year as possible. However, unusual conditions or anomalous information will be reported 

 and exchanged whenever warranted. No unusual conditions occurred during 1 999 which warranted 

 special reporting.
