Dear Mr. De Merdurio:

This is in response to your letter of February 19, 1999, regarding the Hazardous Material, Regulations (HMR; 49 CFR Parts 171-180).  Specifically, you asked us to provide reportable quantity values (RQs) for a hazardous material described as "Environmentally hazardous substance, liquid, n.o.s, UN3082," that contains 2,3,5,6,6- tetrafloro behzyl trans ­2,2,2 -dichlorovenyl and 3,3,dimethylcyclopropane carboxylate.

The HMR require the letters "RQ" to appear on is shipping paper if the haza dous material meets the definition of a hazardous substance (§ 172.20 (c) (2)). As defined in § 171.8, a hazardous substance is a material that is listed in Appendix A to  172.101, is in a package that meets or exceeds the RQ, and when in a mixture or solution, has a concentration by weight which equals or exceeds the concentration corresponding to the RQ of the material as listed in the table in § 171.8. A material must meet all of these requirements in order to be a hazardous substance.  Appendix A lists hazardous substances by their chemical name or waste name, and lists each substance's corresponding RQ value in pounds or kilograms.

You should review Appendix A to determine if the chemicals in your customer's material have RQs.  If the chemicals do not appear in Appendix A, then you need not mark RQ on your shipping paper.  I have enclosed copies of appropriate parts of §§ 171.8, Appendix A to 172.101, and 172.203.

I hope this satisfies your request.
