Capitol Buildings The The Environmental Protection Agency (EPA) published regulations (40 CFR Part In in September 1985 to the Chairman of the Senate Committee on Appropriations and $ 8,000,000 Supplemental Estimates SUPPLEMENTAL ESTIMATES FISCAL YEAR 1986 Capitol Buildings (continued) Replacement of PCB Transformers (continued) Presently, we have one hundred twenty five transformers that contain PCB's in There are two approved methods of handling the PCB problem: retrofilling and replacement. The EPA recognizes the process of retrofilling PCB transformers with non PCB liquids to obtain readings in the 500 PPM (parts per million) range. However, transformers with more than 50 PPM are considered to be PCB contaminated transformers. Present industry experience in retrofilling has not been successful. Initial flushing removes much of the PCB's so that the transformer may test relatively low PCB content. However, retesting later indicates that additional PCBs have leaked into the coolant from the core and coils in the transformer tank. Repeated flushings become uneconomical due to the cost of disposing of the PCB contaminated flushing material. Most of the existing transformers that service the Capitol Hill complex are of an age that warrants their replacement in the near future regardless of the PCB problem. It is therefore proposed to replace rather than retro fill all PCB transformers. The EPA also requires electrical protection for all PCB transformers. This The high voltage cable feeding these transformers is single conductor paper and lead. This consists of a copper conductor insulated with oil filled paper with an outer jacket of lead. No tests have been made to determine if the oil in the cable is contaminated with PCBs. There is no practical way to determine this without destroying the cable. Since this cable enters the high voltage switch on the transformer which is filled with PCBs, it is probable that some length of cable at the transformer switch is contaminated. This cable will be replaced as part of the transformer replacement program. 12.4 |
