Dear Mr. Hayden:
This responds to your request for clarification of the procedures to be used when determining whether a mixture or solution meets the definition of a hazardous substance under the Hazardous Materials Regulations (HMR; 49 CFR Parts 171-180). Specifically, you ask if an item of oil filled electrical equipment (OFEE) that contains approximately 100 gallons of a non-hazardous mineral oil and may be contaminated with up to 500 ppm of polychlorinated biphenyl liquid (PCB) is regulated as a hazard substance under the HMR. The contaminated oil weighs approximately 7 pounds per gallon.
The answer is no. For the purposes of the HMR, a hazardous substance is a material, including its mixtures or solutions that: (1) is listed in Appendix A to the Hazardous Materials Table (HMT) in § 172.101; (2) is in a quantity in one package that meets or exceeds the reportable quantity (RQ) list in Appendix A; and (3) when in a mixture or solution, is in a concentration by weight that equals or exceeds the concentration corresponding to the RQ of the material shown in the table in § 171.8. As indicated in Appendix A to the HMT, the reportable quantity for PCB material is one pound. It would take 270 gallons of a solution weighing 7 pounds per gallon containing 500 ppm of PCB material to meet or exceed the RQ of one pound (7 X 270 = 1890; 1890 X .05 % = 0.945). The maximum amount of contaminated oil in the OFEE you offer for transportation is 100 gallons.
I hope this information is helpful. Please contact us if we can be of further assistance.
Sincerely,
Hattie L. Mitchell
