Dear Mr. Stuhl:
This responds to your August 19,2009 email requesting clarification on the use of a proper
shipping name under the Hazardous Materials Regulations (HMR; 49 CFR Parts 17 1 - 180).
You state that that the proper shipping name "Nitric acid other than red fuming, with more
than 70% nitric acid" no longer appears on the Government Printing Office Electronic Code
of Federal Regulations (eCFR) website in the Hazardous Materials Table (HMT: 49 CFR
172.1 01). Specifically, you ask if we have issued a rulemaking to remove this shipping
description from the HMR, and if not, if you may continue to use the proper shipping name
in compliance with the HMR.
We have not issued any final rules to remove "Nitric acid other than red fuming, with more
than 70% nitric acid" from the HMR. It appears that the shipping description was
inadvertently removed from the eCFR website. You may continue to use this shipping
description in compliance with the HMR. We will work to resolve this discrepancy with the
Government Printing Office as soon as possible.
I hope this answers your inquiry. If you need further assistance, do not hesitate to contact
this Office.

On July 18, 2009, I spoke with Tanikka in your Hazardous Materials Information Center
regarding to the removal from the eCFR HMT of the proper shipping name "Nitric acid other
than red fuming, with more than 70 percent nitric acid". There was a recent Federal
Register notice removing a special provision from that PSN, but there is no indication
that that PSN would be deleted. Tanikka advised me that that PSN was still valid and the
eCFR was in error.
Because the use of that PSN is importannt to our business, and continued use of the PSN
when it is not on the eCFR could be interpreted as a violation, I request DOT provide a
written confirmation that that PSN remains vaild.
