Regulatory Proposals under Development

(New Class TC140 Tank Cars for the Transport of Dangerous Goods)


This proposed amendment is provided for informal comment which means that it has not been published in the Canada Gazette.

Transport Canada has adopted on July 2nd 2014, new requirements for TC/DOT-111 tank cars used in the transport of dangerous goods by rail by incorporating by reference the technical standard TP14877, Containers for the Transport of Dangerous Goods by Rail (CPC 1232). These requirements establish a minimum threshold for rail cars transporting dangerous goods, including petroleum crude oil and ethanol.

Transport Canada is currently considering the development of specifications for an even more robust class of tank cars (known as the “Class TC-140 tank car”) based on industry and the Association of American Railroad Tank Car Committee proposals as well as through technical discussions with the U.S. Pipeline and Hazardous Material Safety Administration (PHMSA). Technical discussions with PHMSA have led to the development of even stricter requirements such as full head-shields, thicker steel, electronically controlled braking systems and improved bottom outlet valves.

This regulatory proposal presents the proposed requirements for this new class of tank cars that would be used for the transport of flammable liquids including petroleum crude oil and ethanol by rail.

Transport Canada expects industry to manufacture any new rail tank car coming into flammable liquid service to meet the new Class TC-140 requirements, once it is in force. Further, Transport Canada also expects that once the standard is adopted in the TDG Regulations, that industry will retrofit all TC/DOT-111 tank cars that transport flammable liquids within the timeframes outlined by these proposed regulations.

Stakeholders are requested to provide their comments on the new proposed Class TC-140 tank car to Transport Canada within 45 days. Following review of comments submitted during this consultation, Transport Canada will move expeditiously with the pre publication of these new requirements in Part I of the Canada Gazette I later in the fall of 2014.
