Gaffney Senior Vice President Reference No.: 00-0212 Jones Chemicals, Inc. .. 100 Sunny Sol Boulevard Caledonia, NY 14423 Dear Mr. Gaffney: This is in response to your July 26, 2000 letter concerning the periodic requalification requirements in 49 CFR 173.34(e) and 49 CFR 180.519(a). You asked if a cylinder or a multi- unit tank car tank that was filled prior to the retest due date may be offered for transportation or continued in transportation after the retest due date, without being retested. The answer is yes, provided the cylinder or multi-unit tank car tank is in proper condition for transportation. See §§ 173.301(c) and 173.31(a)(3). You are also correct in your understanding that a cylinder may not be refilled after the last date of the month of the calendar year during which the retest is due unless it has been retested. That is, using your example, a cylinder with a July 1995 test date and on a five-year retest schedule may not be refilled after July 31, 2000, unless the retest has been performed. You are also correct in your understanding that a multi-unit tank car tank may be retested anytime during the calendar year the retest falls due. See § 180.519(a). Again, using your example, a multi-unit tank car tank with a July 1995 test date and on a five-year retest schedule been performed. may not be refilled and offered for transportation after December 31, 2000, unless the retest has I hope this information is helpful.

Regarding 49 CFR 180.519(a), it is our understanding that multi-unit tank car tanks (for example DOT- 106A500 with a retest interval of 5 years) cannot be refilled after the last day of the YEAR during which he retest is due, unless it has been retested. As an example, a multi-unit tank car tank with a test date of interpret the sentence in these regulations "Retests may be made at any time during the calendar year the July 1995 cannot be refilled after December 31, 2000, unless it has been retested.
