Pipeline and Hazardous Materials Safety Administration APR 7 2007 Mr. Mark Connolly Ref. No.: 07-0069 Akzo Nobel Chemicals Inc Manager Transportation Regulations and Security 300 South Riverside Plaza Chicago, IL 60606-6697 Dear Mr. Connolly: This is in response to your March 23, 2007 letter regarding the schedule for the periodic inspection and test of IM and UN portable tanks under the Hazardous Materials Regulations (HMR; 49 CFR Parts 171-180). In your letter you describe a scenario in which the initial inspection and test before the portable tank was put into service was performed in May of 2002 2004; that is, two months early. You ask if an additional intermediate periodic requalification and the intermediate periodic test and inspection (requalification) was performed in September of requalification. must be performed in March of 2007; that is, two months prior to the 5-year periodic The answer is no. In accordance with § 180.605(c)(1), an intermediate periodic requalification must be performed at least 2.5 years following the initial inspection and thereafter every 2.5 requalification schedule contained in the HMR with that contained in the United Nations' years following the 5-year periodic requalification. It was our intention to align the periodic Recommendations on the Transport of Dangerous Goods. Paragraph 6.7.2.19 of the UN Recommendations provides for the 2.5-year intermediate periodic requalification to be performed within 3 months of the specified date. We take a similar position in this matter. Therefore, in the scenario described in your letter, the next required inspection and test, the 5- year periodic requalification, is due May 2007. I hope this information is helpful. If you have further questions, please do not hesitate to contact this office. Sincerely. Hattie L.
