AJtTh> New PCB rules offer FYI: J. H. Craddock - B3WA J- G. Massif - E2ND more protection--CMA Dan Blahop 9-28-84 CMA considers EPA'* recently issued regulations governing the inadvertent generaln of polychlorinated biphenyls (PCBs) to be "effective, reasonable rales that wtti provide an increased level of protection for the environment/' The final regulations are based in large part on a consensus proposal submkted la iht agwey Imt April by CMA. the Natural Resources Defense Council and the Environmental Defense Fund. That propped was the reeuH of Defoliations --long the three orfanixations fottowinf a 1900 federal appeals court decision that struck down parts of the agency's original regulations implementing the Teak Substances Control Act ht 1979. the government banned the manufacture of PCBa because ofreports of widespread contamination in the en vironment, but it permitted the con tinued use ofPCBs in equipment such as tunsfnrmirs snd capacitors. PCBs an, however, inadvertently generated as un warned byproducts of various.manufac turing processes. Since the ban five years ago, the amount of PCBs in the swviromnsnt has stsadBy declined becauae of curtailed use, proper disposal and environmental degradation. Basically, the final EPA rale: Limiu PCBs inadvertently gener ated in products to an average mnual concentration of 25 parts per million (ppm), and sets s 50 ppm maximum. Establishes concentration limits of 10 ppm on releases of inadvertently generated PCBs to the air and 0.1 ppm to water. Specifies how inadvertently gener ated PCBe are to be measured. Specifies certification, reporting and record maintenance requirements. Dr. Kenneth Burgess, chairman of CMA's PCB Proyam Panel, said the publication of the new rules, "has sig nificance beyond the obvious reason that they establish affective controls. "They demonstrate quite convincing ly what government, industry and organ isations like NRDC and EDF can ac complish by working together to find effective, reasonsbit solutions to envi ronmental issues." The three groups, Burgess said, "have demonstrated ones again that negotia tion and agreement are not only possible between organisations like ours but are more beneficial and productive than litigation."
