Dear Mr. Forbes:
This letter is in response to your May 1, 2025 email requesting clarification of the Hazardous Materials Regulations (HMR; 49 CFR Parts 171-180) applicable to the marine pollutant marking requirements. Specifically, you ask if it is a violation of the HMR to not display a marine pollutant marking on a Commercial Motor Vehicle (CMV) carrying multiple hazardous materials (including a marine pollutant) that bears a placard or label specified in subparts E or F of Part 172 on said CMV?
No. As stated in § 172.322(d)(3), the marine pollutant mark is not required on a bulk packaging, freight container, or transport vehicle that bears a label or placard specified in subparts E or F of Part 172. As you stated in your letter, the CMV is placarded; therefore, the marine pollutant marking is not required.
I hope this information is helpful. Please contact us if we can be of further assistance.
Sincerely,
Alexander Wolcott
Acting Chief, Regulatory Review & Reinvention Branch
Standards and Rulemaking Division
172.322(d)(3)
