No. 16-0100\nDear Mr. Smith:\nThis responds to your June 7, 2016 email requesting clarification of the Hazardous Materials\nRegulations (HMR; 49 CFR Parts 171-180) applicable to anhydrous ammonia being regulated\nas a marine pollutant. Your questions are paraphrased and answered as follows:\nQ1. What does the \"(I)\" located behind \"Ammonia, anhydrous\" in Appendix B of the\n§ 172.101 Hazardous Materials Table indicate?\nAl. It indicates that a hazardous material that has been classified under the international\nentry, \"UN 1005, Ammonia, anhydrous, 2.3\"' is regulated as a marine pollutant if it also meets\nthe definition of a marine pollutant in § 171.8.\nQ2.\nWhy is \"Ammonia, anhydrous\" transported under the domestic entry not listed as a\nmarine pollutant under Appendix B of the HMT while \"Ammonia solutions\" is regulated as a\nmarine pollutant domestically?\nA2. A final rule published on January 8, 2014 [(HM-215M); 80 FR 1075] revised\nAppendix B to § 172.101 by adding sixty-two new entries to the List of Marine Pollutants to\nharmonize with the International Maritime Dangerous Goods (IMDG) Code. However, we\nchose not to impose new requirements on the transportation of \"ammonia, anhydrous\"\ndomestically because of the authorized classification as Division 2.2 for domestic\ntransportation.\nI trust this satisfies your inquiry. Please contact us if we can be of further assistance.\nSincerely,\nLet the\n1. 9\nDirk Der'\nChief, Standards Development Branch\nStandards and Rulemaking Division\n\n<<<PAGE 2>>>\n\nCiccarone\n§172.101\nHMT\nDodd, Alice (PHMSA)\n16-0100\nFrom:\nRivera, Jordan CTR (PHMSA)\nSent:\nTuesday, June 07, 2016 11:45 AM\nTo:\nHazmat Interps\nSubject:\nFW: Request Formal Interpretation on Ammonia, Anhydrous (I) in Appendix B of HMT\nHi Shante/Alice,\nPlease submit this as a letter of interpretation.

The only place I see the \"(I)\" mentioned is in 172.101(a)(5)\nbut that only address the HMT column 1 entries?\nQ2: If Ammonia, anhydrous is only regulated as a \"Marine Pollutant\" for international shipments; why wouldn't Ammonia\nSolutions be considered exempt from domestic shipments as well; since they are environmentally less toxic to the Marine\nenvironment than Anhydrous Ammonia which is in a 99 - 100% concentration of Ammonia?\nThank you very much,\nMailing Address is :\nNorthbrook, IL 60062\n1101 Skokie Blvd., Ste 400\nMr. Tracey G.
