Savage When dealing with historical production and sales figures for dielectrics it becomes quite Important for all concerned to put them Into proper perspective, especially from the stand point of the higher PCB (Aroolor 1254 and Aroclor 1260) con tent relative to the PCB pollution problem. Product ohangeB took plaoe. 7or example In the capacitor In dustry: Approx. Higher PCB Prime Product Prime Product Content 5 Cl and higher gee Period %Aroolor 1254 Aroolor 1242 Aroclor 1016 To about 1952 1952-1970 1971 1970 was the historical high year for pounds of capacitor Aro olor use In the USA at near 26 H lbs. We do not expect this level to be exceeded for some years to come. Mow to reflect the elimination of higher PCBs from oapac^tor Aroolor,taking In account product changes and using, iX97tsales as basis for comparison we have: 1970 Basis for Comparison Product Higher PCB Involvement Pounds Aroclor 1254 26 R x 7638 19,760,000 Aroclor 1242 26 R x 7J* 1,820,000 Aroclor 1016 26 R x 0.3 78,000 1. If Aroolor 1254 had continued In use the higher PCB In volvement would have been near 20 R pounds. 2. In 1970 Aroolor 1242 was the prime product and the higher PCB involvement was 1.82 R pounds. 3. Now Aroclor 1016 Is used exclusively and the higher PCB Involvement based on 1970 sales would have been 78,000 pounds. MONS -2Conoluslon At this time and for the foreseeable future the Involvement with the acknowledged non-blodegradable 5 chlorine and higher PCBs from the entire USA capacitor Industry does not appear to exceed about Vo,066 pounds annually.
