The Association of American Railroads (AAR), along with the railway supply industry, formally petitions the Pipeline and Hazardous Materials Safety Administration (PHMSA) to amend the hazardous materials regulations to require the use of an enhanced Class-111 tank car to transport ethanol and petroleum crude oil. The industry’s designation for the new tank car standard is an “enhanced Class-111 tank car,” or a “CPC-1232 tank car,” based on the AAR circular letter number, “CPC-1232.” [Read Petition]
