Transport Canada’s May 1st announcement of a TDGR amendment was formalized in the May 20th edition of CGII. This amendment, SOR/2015-100 (“TC 117 Tank Cars”), phases in the requirement for the upgraded TC 111 and basic-enhanced TC 117 rail tank cars for flammable liquid service (see my Blog of May 4th).
The amendment details the enhancements required to the basic tank car design and construction in TP14877 for use in service for flammable liquids. TP14877, published in 2013, was formally adopted in July 2014 and became mandatory in January. Subsequent incidents and recommendations have led to these extra measures to provide a stronger tanker in conjunction with other operating procedures to improve rail safety for flammable DG transportation.
On the related topic of rail tanker ERAP (emergency response assistance plans-TDGR Part 7), the amendment clarifies the requirements as they apply to rail tankers and true flammables.
