# Con-Way Truckload — Hazardous Materials Safety Interpretation **Citation:** 13-0035 **Type / status:** guidance / guidance **Agency:** Pipeline and Hazardous Materials Safety Administration **Effective:** Not stated **Published:** 2013-11-13 13-0035 response to Con-Way Truckload concerning 171.2, 177.800, 177.843. ## Document text <<>> U.S. Department of Transportation Pipeline and Hazardous Materials Safety Administration 1200 New Jersey Avenue, SE Washington, D.C. 20590 NOV 1 3 2013 Mr. JeffMesser Safety Analyst Con-Way Truckload 4701 E. 32nd Street Joplin, MO 64803 Reference No. 13-0035 Dear Mr. Messer: This is in response to your e-mail and subsequent emails and telephone conversations supplying additional information pertaining to clarification of the Hazardous Materials Regulations (HMR; 49 CFR 171-180) applicable to a transporter relying on information concerning hazardous material shipments, when those shipments are prepared for transportation by the offeror. Specifically, you state that you are an over-the-road commercial carrier that transports trailers loaded and pre-sealed by the offeror. You further state that your drivers do not unseal the trailers and open them to inspect the loads. At times, your drivers have been subject to roadside inspections and required to open the trailers. As a result, the drivers have been cited for not complying with the requirements of § 177.834(a). You are requesting an interpretation to determine if you are correct in your understanding that the enforcement citation should go to the offeror. To support your understanding, you cite § 171.2(f), pertaining to exercising reasonable care in the reliance on information provided by an offeror or prior carrier; § 171.8, pertaining to the definitions for "person who offers or offeror" and "pre-transportation function," including "(12) loading, blocking, and bracing a hazardous materials package in a freight container or transport vehicle;" and§ 177.800(b), pertaining to a carrier's responsibility for compliance with Part 177, "Carriage by Highway," unless specifically provided that another person shall perform a particular duty. Additionally, you state that under§ 173.30, pertaining to the loading and unloading of transport vehicles, the responsibility falls on the person loading and unloading the hazardous material to comply with§ 177.834, although § 177.834 is a requirement under the Part 177, "Carriage by Highway." Lastly, you state it is your belief that§ 177.801 and not§ 177.834 is the correct citation reference for a violation. Your understanding of pre-transportation function responsibility is partially correct. Although responsibility for compliance with Part 177 of the HMR is inherently placed on the motor carrier, pre-transportation and other regulated functions (e.g., loading, blocking, and bracing of a hazardous materials package into or onto a motor vehicle) can be performed <<>> by more than one party. Thus, an offeror and a motor carrier may both be held responsible for non-compliance with applicable requirements of Part 177 of the HMR. However, in the scenario where trailers have Customs Seals or security seals (to prevent theft or contamination), and the driver has no way to inspect the load, the onus for compliance could fall on the shipper/offeror. Regarding a motor carrier's responsibility, no person may transport a hazardous material in commerce unless the hazardous material is transported in accordance with applicable requirements of the HMR. In other words, as specified in§ 177.800, unless otherwise provided, each carrier, including a connecting carrier, shall perform the duties specified and comply with applicable requirements in Part 177, including, but not limited to, the general package securement requirements specified in § 177.834. However, under§ 171.2(±), a motor carrier who transports a hazardous material in commerce may rely on information provided by the offeror of the hazardous material, unless the motor carrier knows or, a reasonable person, acting in the circumstances and exercising reasonable care, would have knowledge that the information provided by the offeror is incorrect. The degree of a motor carrier's culpability is measured by whether the loading, blocking, or bracing violation could have been avoided by exercising reasonable care. An example of exercising reasonable care could be where the trailer was not sealed until after motor carrier personnel, or someone acting on its behalf, examined the trailer for proper cargo securement. Regarding an offeror's responsibility, any person who performs, attempts to perform, or, under the circumstances involved, is contractually or otherwise responsible to perform, any of the regulated transportation functions subject to the HMR is legally responsible under the HMR for their proper performance. Thus, the degree of an offeror's culpability is also measured by whether the loading, blocking, or bracing violation could have been avoided by exercising reasonable care. I trust this information is helpful. Please contact this office should you have additional questions. Sincerely, T.

Thanks, Victoria From: Jeff Messer [mailto:me ser.·eff conwa ruckload.com] Sent: Monday, February 04, 2 13 4:09PM To:INFOCNTR(PHMSA) ' Subject: Formal Letter of Interpretation February 04, 2013 U.S. DOT \ PHMSA Office of Hazardous M~terials Standards Attn: PHH-10 East Building 1200 New Jersey Avenue, SE. Washington, DC 20590-0001 To Whom It May Concern: As an over-the-road commercia'! hauler, we are often. asked t~ pick up trailers that have already been loaded and pre- sealed by the offeror. Our drivdrs do not unseal the. trailer and open it to inspect the load. There have been times that we have been inspected by law ~nforcement and have· been required to 'open the trailer at that time. We have been cited '\ for not complying with the requ,rements of Subpart B-Loading and Unloading 177.834(a). We are requesting an interpretation to determine if Wf are correct in our assertion that the citation should go to the offeror based on the following logic: I i I 177.800{b) Responsibiltjty for compliance states that "Unless this subchapter specifically provides that another person shall perform a particular duty." I I 171.2(!) states that "Eac~ carrier who transports a hazardous material in commerce may rely on information provided by the offeror ~f the hazardous material or a prior carrier, unless the carrier knows ... that the information provided by the offeror $r prior carrier is incorrect". II 171.8 Person who offers pr offeror means (1) Any person who does either or both of the following: (i) Performs or is\ responsible for performing any pre-transportation function required under this subchapter for t~ansportation of the hazardous material in commerce. (ii) Tenders or mO,kes the hazardous material available to a carrier for transportation in commerce I 1 <<>> 171.8 Pre-transportation/unction means a function specified in the HMR that is required to assure the safe transportation of a hazardous material in commerce, including- (12) Loading, blocking, and bracing a hazardous material package in a freight container or transport vehicle Based on these citations, we feel that the requirements of 177.834 are a pre-transportation function for which we are relying on the offeror to perform correctly as is their regulatory responsibility. Furthermore all subsections of 177.834 specifically speak to load and unloading procedures done by the offeror. As such, it is our opinion that the offeror should be the entity who receives the citation if there is a violation of 177.834. Please feel free to contact me for further clarification of our position on this matter. Thank you in advance for your time.
