Specifically, you ask whether the HMR prohibits the transportation of a filled or partially filled CTMV on a RGN trailer. The answer is no, the HMR does not prohibit the transportation of a filled or partially filled CTMV on a RGN trailer. Please note that all applicable HMR requirements, including hazard communication such as markings and placards, continue to apply when the filled or partially filled CTMV is the object of carriage, rather than the actual vehicle used to transport the hazardous material cargo. Also, please be aware that§ 177.834(a) requires that the CTMV be secured against shifting during transportation while loaded on the RGN trailer. I hope this information is helpful. Please contact us if we can be of further assistance. Smc, ~_/4 2, ~ ei:7' Chief, Standards Development Branch Standards and Rulemaking Division#

Thanks, Kathryn, HMIC NOTE: Spoke with requester and he verified the bulk containers are approved for his specific materials. From: Tim Farrell [mailto:tim@aca-int.com] Sent: Tuesday, August 6, 2019 9:52 AM To: INFOCNTR (PHMSA) <INFOCNTR.INFOCNTR@dot.gov> Subject: REQUEST FOR LETTER OF INTERPRETATION: QUO0000024 Request regarding bulk movement of UN1202 and UN1978 Hello: We had sent a question in about the movement of bulk fuel vehicles by RGN trailer while filled with DG fuels. Robert from the DOT customer service center contacted us to advise it would be allowable as long as the vehicles are approved bulk fuel containers. In order to confirm to the carriers this is true, we are asking to be sent an official letter of interpretation on the matter. To restate our question: We are looking to move fuel trucks that are filled with fuel by loading them onto RGN trailers. During the shipment they would be filled with DG fuels such as UN1202 and UN1978 (SDS's attached). The vehicles we would be moving are DOT approved as bulk containers. We would use them as single packaging on the RGN trailer to carry the fuel to destination. We would like an official letter of interpretation to state that this is allowable under DOT /PHMSA guidelines. Requesting Party: ACA International LLC DOT# 3107313 MC #80822 129 Newbury Street 2nd Floor Boston, MA 02116 646-843-0700 Please let me know if you have any questions or if I can further clarify what we are looking for in our letter. 1#

I have a customer who owns a fuel company and they are looking for assistance to move their fuel tankers from the east to the west coast over the road. The vehicles are currently DOT certified for carrying the bulk DG but we were wondering if the trucks themselves could be considered single packaging if we wanted to load out multiple full trucks onto an RGN. Do you have any insight into the possibility of this or any suggestions on where to get more information? Please see sample SOS sheets for these commodities attached.

The information below is given to call attention to the issue of "Naturally occurring radioactive materials". Although Radon-222 levels in the product represented by this MSDS do not present any direct Radon exposure hazard, customers should be aware of the potential for Radon daughter build up within their processing systems, whatever the source of their product streams. Radon-222 is a naturally occurring radioactive gas which can be a contaminant in natural gas. During subsequent processing , Radon tends to be concentrated in Liquefied Petroleum Gas streams and in product streams having a similar boiling point range. Industry experience has shown that this product may contain small amounts of Radon-222 and its radioactive decay products, called Radon "daughters". The actual concentration of Radon-222 and radioactive daughters in the delivered product is dependent on the geographical source of the natural gas and storage time prior to delivery. Process equipment (i.e. lines, filters, pumps and reaction units) may accumulate significant levels of radioactive daughters and show a gamma radiation reading during operation. A potential external radiation hazard exists at or near any pipe valve or vessel containing a Radon enriched stream, or containing internal deposits of radioactive material due to the transmission of gamma radiation through its wall. Field studies reported in the literature have not shown any conditions that subject workers to cumulative exposures in excess of general population limits. Equipment emitting gamma radiation should be presumed to be internally contaminated with alpha emitting decay products which may be a hazard if inhaled or ingested. Protective equipment such as coveralls, gloves, and respirator (NIOSH/MHSA approved for high efficiency particulates and radionuclides, or supplied air) should be worn by personnel entering a vessel or working on contaminated process equipment to prevent skin contamination, ingestion, or inhalation of any residues containing alpha radiation. Airborne contamination may be minimized by handling scale and/or contaminated materials in a wet state. Notice to reader To the best of our knowledge, the information contained herein is accurate.
