2. Last year when Mayor Koch appeared before this Committee, I 

 asked if the City would furnish for the Record the number of 

 tons of PCB's, mercury, cadmium, lead, copper and other 

 heavy metals and toxic materials which are routinely 

 deposited in the ocean each year out of New York City 

 through sewage sludge dumping. These figures were never 

 provided. Could you now provide this information to the 

 Committee? 



When the Committee originally requested this information, New 

 York City's consultant was in the process of preparing estimates 

 of annual contaminant loadings to the New York Bight apex from 

 all sources. The City submitted those estimates to EPA on March 

 9, 1983, in response to a December 9, 1982 letter from the EPA 

 Region II Administrator which requested technical information 

 concerning redesignation of the 12-Mile Site, and also in 

 response to EPA's December 20, 1982 Federal Register Notice (47 

 FR 56665) which requested similar information. Copies of the 

 submission to EPA have already been provided to the Committee. 



The City's comment documents to EPA provided the estimates 

 sought by the Committee and explain the methods employed to 

 prepare those estimates. In preparing those documents, the 

 City's consultant performed a thorough and extensive analysis of 

 mass constituent loadings to the New York Bight apex and 

 compared the relative contribution of most contaminants from 

 each source. The attached Tables 1 through 3 are the data 

 resulting from that analysis and are taken from the City's March 

 9, 1983 Comments to EPA (NYC 1983). Table 1 (Table 6-16 in the 

 City's 12-Mile Site comment document) presents estimates of the 

 current annual loads of contaminants from New York City and from
