D.C. 20590 JUN 07 2010 Mr. Dave Finlay Regional HSSE Manager - Americas Wilhelmsen Ships Service 9400 New Century Drive Pasadena, TX 77507 Ref. No.: 10-0100 Dear Mr. Finlay: This responds to your April 19, 2010 email regarding the applicability ofthe Hazardous Materials Regulations (HMR; 49 CFR Parts 171-180) to a particular CGA publication. Specifically, you ask whether the HMR requires testing ofcylinder valves to be in accordance with the Compressed Gas Association publication, CGA V-9, "Standard for Compressed Gas Cylinder Valves." The answer is no. Currently, § 171.7(a)(2) ofthe HMR do not incorporate by reference the CGA V-9 publication. However, the outside of cylinders are required by § 173.301(a)(2) to be visually inspected prior to each filling. Any cylinder having a defective valve or other detrimental damage may not be filled and offered for transportation. 1 trust this satisfies your inquiry. Please contact us if we can be of further assistance. Hattie L. Mitchell Chief, Regulatory Review and Reinvention Office of Hazardous Materials Standards <<>> Drakeford, Carolyn (PHMSA) From: Finlay, David [David.Finlay@wilhelmsen.com] Sent: Tuesday, April 20, 2010 11 :38 AM To: INFOCNTR (PHMSA) Subject: FW: C02 valve reconditioning Attachments: CGA V9 Valves. pdf; WSE-50-03-018_Technical bulletin.doc Sir As discussed. We have always used CGA P-15 2.4.3 as our guide which states valve "outlets should be in good condition with clean sharp threads and an undamaged seating surface. If not the valve should be replaced". Although the damage to the valve outlet is minimal, our fear is that we could have liability if we follow the suggestion below. We are also asked to seek USDOT approval for this which is why your opinion is so important to us. My thanks for your quick response it is much appreciated.
