Box 16828\nPhiladelphia, P A 19142\nRef. No.: 10-0198\nDear Mr. Guevara:\nThis responds to your September 3, 2010 letter requesting clarification of the emergency discharge\ncontrol requirements for cargo tank motor vehicles (CTMVs) under the Hazardous Materials\nRegulations (HMR; 49 CFR Parts 171-180). You have attached a guidance document intended to be\ndistributed to your clients for compliance assistance. The guidance document summarizes the\npassive shut-down requirements in § 173.315(n) and includes a list of materials that would require\npassive shut-down capability under the HMR. Specifically, you ask confirmation that the list of\nproper shipping names in your guidance document accurately identifies materials that would require\npassive shut-down capability under § 173.315(n).\nThe table in § 173.315(n)(I) specifies emergency discharge control requirements for CTMV s in\nliquefied compressed gas service. The requirements are specific to the type of material being\ntransported, the type of service (Le., metered delivery or unmetered delivery), and whether the person\nattending the unloading operation has an unobstructed view ofthe cargo tank and delivery hose.\nPHMSA is supportive ofyour efforts to list all of the materials and the circumstances that would\nrequire a passive shut-down capability in accordance with §§ 173.315(n)(I) and (n)(2) in a single\nguidance document to assist your clients with compliance. However, it is not PHMSA's policy to\nreview, approve, or endorse specific guidance documents developed and published by nongovernment\nentities.\nI trust this satisfies your inquiry. Please contact us ifwe can be of further assistance.\nSincerely,\n~~\nBen Supko\nActing Chief, Standards Development\nOffice ofHazardous Materials Standards\n\n<<<PAGE 2>>>\n\nf:i ()~ tn IClUb\nStuart-Hose'\n~/13. 3/5(ni?)\n• CarSo T@J.\n~TECHNOLOGIES~\n•\nSeptember 3, 2010\nCharles E.

We have\nconducted a review of 49 CFR 173.315 (n)(2), specifically regarding which chemicals\nare included in the mandate for a passive shutoff device. Our review has resulted in\nthe attached list of materials. We would like to receive confirmation that our list is\ncorrect before we begin using the list to assist our customers. Your review and\ncomments would be greatly appreciated. Thank you.\nSincerely,\n~.~\nAndrea Guevara\nPresident\nMail to: P.O.
