Dear Mr. Millan:
This is response to your letter dated October 1, 1999, concerning the definition of hazardous substance under the Hazardous Materials Regulations (HMR; 49 CFR Parts 171-180).
Under § 171.8, a hazardous substance is defined as a material, including its mixtures and solutions, that: (1) is listed in Appendix A to § 172.101 of the HMR; (2) is in a quantity, in one package, which equals or exceeds its reportable quantity; and (3) is in a concentration by weight which equals or exceeds the concentration corresponding to the RQ of the material, as shown in the table under § 171.8.
For example, n-Butyl phthalate has an RQ of 10 pounds. To meet the definition of a hazardous substance, the quantity of n-Butyl phthalate in each package must equal or exceed 10 pounds, and the concentration by weight must be equal to or be greater than 0.02% (200 ppm).
I hope this satisfies your request.
Sincerely,
John A Gale
