A representative of the National Federation of Federal Employees, Local 422 requested a study be made of skin problems being experienced by several employees of the Colorado River Agency (SIC- 4911) which might be linked to transformer oil or polychlorinated biphenyl (1336363) (PCB) exposures. Out of service transformers have been stored at the Agency which has operated as a power yard since the 1930's. Old transformer oil was being used as a spray to control dust in the yard at the Agency in 1982 until it was learned that it might contain PCBs. No oil samples contained PCBs, but samples of sprayed soil in 1982 contained 79ppm PCBs in 1982. Contaminated transformers and accessories were removed from the yard. Several air samples were collected in April of 1986 along with wipe samples. Bulk soil samples were also taken. According to the authors, no airborne exposures to PCBs could be documented but there was contamination of vehicles used to handle the transformers as determined by the wipe samples. Bulk soil samples indicated contamination of the yard, particularly at a low spot in the yard. The authors recommend that vehicles be wiped down with kerosene to obtain thorough decontamination and then the kerosene be disposed of as contaminated material.
