Polychlorlnatod Biphenyl* NO TYPE OP EXPOCURE TO PCBa It INSIGNIFICANT, EOF TELLS EPA Because of their persistence in the environment and highly toxic effects, no type of exposure to polychlorinated blphonyl* can be termed as insignificant, according to Joseph Hyland of the Environmental Defense Fund. Al an Environmental Protection Agency hearing July 15 in Washington, Hyland told an agency panel that the use of PCBa in a "totally enclosed manner" Is impossible. SPA held the hearing to receive comments from the public Klor to proposal of regulations for carrying out the phased n on PCBs, the second phase of action against the chemicals under (he Toxic Substances Control Act. Section 6(e) of TSCA provides that after January 1, 2979, PCBs may not be manufactured, processed, distributed in com merce, or used in other than a "totally enclosed manner." After July 1. 1979, no PCBs may be manufactured, process ed, or distributed in commerce. . EPA currently is considering comments on Us proposed - regulations for the labeling and disposal of PCBs -- the first phase of action Against the chemicals under TSCA (Current Report, July J, p. 603). Reside Provisions Herbert T. Gllky, director of public affairs. Air Con- diliumng and Kcfvigcrntion Institute, said his industry is co<t* cerned with the resale provisions of TSCA -- when docs one stop selling PCBs as such and start selling something that contains PCBs? Cilky rai l that capacitors weighing three pounds or lers. which contain l*CBs as a dielectric, are a small, but impor tant part of air-conditioning units. ilylaml commented. however, that even exposure to sealed capacitors is significant through the production and disposal of the capacitors. Hyland said that EDF is opposed to the further sale of ex isting stockpiles of PCBs and believes that such stockpiles should be incinerated. EDF also advocates slricl restric tions on the disposal of PCB-contaminated sludge on land, he said. PCB use should be restricted only to the servicing of ex isting equipment. Hyland said, and no further production of the chemicals should be permitted. Government Stockpiles Although the paper manufacturing process does not use PCBs, contamination from PCBs in recycled paperboard Is posing a problem for the paper industry, accoroing to an in dustry official. Richard Wicchmann, director of environmental affairs for the American Paper Institute, told the EPA panel that PCBs were used as an encapsulating agent in ink at a concentra tion of about 3 percent. Although the practice was stopped in 1971, he said, the ink was used mainly on business forms used primarily by the Government for such uses as Internal Revenue Service W-2 forms. A problem now exists with the Government stockpiling the old forms and then recycling them, he said. The contaminated business forms, which have a PCB con tent of about 30,000 parts per million (ppm), are iccycled Into pui>erbonrd, Wiecbmann said. The Food ami Drug Ad ministration has sot a tolerance of 10 ppin for PCBs in recycled foodboard, he saidnind the paper industry has set up a quality control program to prevent contamination of the foodboard. No such program exists to prevent contamination of other forms of paperboard, however, he said. Contaminated Waate Oil Robert Magruder, Continental Forests industries, Hopewell, Va.. told the EPA panel that his company is con cerned about its future use of PCB-contaminated waste oil. Magruder said his company uses used crankcase oil, collected mainly from service stations in Maryland, North Carolina, and Virginia, in the operation of about one-half of their steam generating units. Although the company has In formed their collectors that they do not want the con taminated oil, he said, they have no way of assuring that the used waste oil will be free of contamination. Magruder said that the impact of burning the con taminated waste oil is "minimal" and the process "almost qualifies as a PCB incinerator." Reprocessing the con taminated oil does not remove the PCBs, he said. If the use of PCB-contaminated waste oil is banned after 1979 or 1979, Magruder said, the company will be forced to turn to more expensive oil, thereby increasing energy im ports and eliminating a means of disposing of the PCB-contaminatod oil at low cost. Mining Operations James Petrie, health specialist for the Interior Department's Mining Enforcement and Safety Administra tion, queflioned wlictbei the use of PCB-cnoted oneiric motors in mining operations would be considered a "totally enclosed manner."
