The Environmental Protection Agency requested information about the use and concentration of PCBs found in certain non-liquid PCB applications or products for the December 6,1994 Proposed rule
The following brief descriptions of non-liquid PCB use information submitted to EPA are taken from pages 69358-69364 [FR Doc. 99-32079]
Insulation (e.g., wool felt, foam rubber and fiberglass) and sound-dampening materials. These materials have been found to contain PCBs at concentrations which exceed 50 ppm. Fiberglass insulation containing PCBs has been found in federally owned buildings at various concentrations. Bulk PCB concentrations were reported to range between <1>
Plastics, small foam rubber and rubber parts, adhesive tape, and insulating materials used in electrical cabling.
Paint formulations
Fluorescent light ballast potting materialsGaskets in heating, ventilation and air conditioning (HVAC) and other duct systems.
Coatings for ceiling tiles. Ceiling tiles contaminated with PCBs have been found at educational institutions with surface level PCB concentrations at a maximum of 53 ppm.
Flooring and floor wax/sealants.
Roofing and siding materials. This material was manufactured and marketed worldwide as Robertson Protected Metal (RPM) and Galbestos to airlines, railroads, chemical plants, steel mills, mines, industrial/manufacturing facilities, and military facilities.
Caulking and grout. Samples of caulking that have been contaminated with PCBs have been found in a setting previously used as a school at a maximum concentration of 310,000 ppm PCBs
Waterproofing compounds, anti-fouling compounds, and fire retardant coatings.
Coal-tar enamel coatings for steel water pipe and underground storage tanks
