No. 07-0034 Motor Carrier Compliance Division jeorgia Department of Public Satet P.O. Box 1456 Atlanta, GA 30371-1456 Dear Captain Bugg: This responds to your February 12, 2007 letter requesting clarification on the applicability of § 172.328(d) of the Hazardous Materials Regulations (HMR; 49 CFR equipped with remote emergency closures, or only to specification cargo tanks that are Parts 171-180). Specifically, you ask if this section applies to any cargo tank that is required to have self-closing internal stop valves. Section 172.328(d) requires that after October 3, 2005, each on-vehicle manually- activated remote shutoff device for closure of the internal self-closing stop valve must be identified by marking "Emergency Shutoff" in letters at least 0.75 inches in height, in a color that contrasts with its background, and located in an area immediately adjacent to remote emergency closures. These cargo tanks include MC 330 and MC 331 the means of closure. This requirement applies to any cargo tank that is equipped with specification cargo tanks under Part 180, Subpart E, as well as non specification cargo tanks carrying liquefied petroleum gas in accordance with provisions in § 173.315(k). I hope this answers your inquiry. Sincerely, ( Chief, Standards Development Office of Hazardous Materials Standards 172.328 (d). 070034 173.315 (к)#
