No. 05-0065 PurePak Corporation 324 S. Bracken Lane, Suite #3 Chandler, AZ 85224 Dear Mr. Giaccio: This is in response to your March 22, 2005, letter requesting clarification of the Hazardous packagings for the combination packaging specified in §173.158(f(3) must have a maximum Materials Regulations (HMR; 49 CFR Parts 171-180). Specifically, you ask if plastic inner capacity that is not greater than 2.5 L or whether a larger container can be used and only filled to 2.5 L. Nitric acid of 70% or less concentration offered for transport by rail, highway, or water may be packaged in certain combination packagings with plastic inner packagings not over 2.5 L capacity further individually overpacked in tightly closed metal packagings (§ 173.158(f)(3)). The use of the term "not over" means that you may not use a plastic inner packaging with a maximum capacity greater than 2.5 L. I hope this satisfies your request. Sincerel John A.
