Department\nof Transportation\n400 Seventh Street, S.W\nWashington, D.C\n20590\nResearch and\nAdministration\nSpecial Programs\nMAY 1 7 2001\nMr. Clay Sutter\nRef. No. 01-0119\nShop Foreman\nWhite Tank and Truck Repair\nP.O. Box 469\nBelleville, Illinois 62222\nDear Mr. Sutter:\nThis responds to your May 13, 2001 letter concerning specification requirements for MC 306\ncargo tanks authorized for the transportation of hazardous materials by the Hazardous Materials\nRegulations (49 CFR Parts 171-180; HMR). Specifically, you ask about damage protection\nrequirements for a rubber vapor boot and connecting metal piping installed on the top of an\nMC 306 cargo tank.\nGenerally, the HMR permit a rubber attachment, such as the vapor boot pictured in your letter, to\nextend beyond a cargo tank's accident damage protection device. However, metal piping that\nextends above the accident damage protection may result in leakage of the lading if struck during\na rollover. Any device that could result in leakage of lading if struck during a rollover may not\nextend beyond an accident damage protection device unless it is equipped with a stop valve and a\nsacriticial device such as a shear section. The sacrificial device must be located in the piping\nsystem outboard of the stop valve and within the accident protection device to prevent any\naccidental loss of lading. If the metal piping pictured in your letter is not equipped with a stop\nvalve and a sacrificial device, then the cargo tank should be removed from service until\nappropriate modifications to the piping are completed.\nI hope this information is helpful. If you have further questions, please do not hesitate to contact\nthis office.\nSincerely,\nhomas G.
