CAAR and Fertilizer Canada are in the process of completing an application for a Temporary Certificate in support of the anhydrous ammonia industry. A request for compliance reprieve for nurse and applicator tanks is in development to meet: 

  • Section 5.10 (1) of the TDGR; 
  • Visual Inspection requirements in Specific Requirement 55 of the CSA B622-14 Standard.

In support of this application, Transport Canada has requested additional information from anhydrous ammonia nurse and applicator tank owners. Specifically, the industry has been asked to provide a definitive number of nurse and applicator tanks that require a reprieve for the spring 2018 season. The criteria for reprieve applied for is as follows:

As per the references in the Transportation of Dangerous Goods Regulations, in particular Part 5.10 (1), regarding the testing/inspection requirements of the CSA B622-14: Non-specification tanks are required to be hydrostatically tested every 3 years (CSA B622-09 required every 5 years) and visually inspected annually as listed in Specific Requirement 55 (a).

Update on Temporary Certificate Application for Hydrostatic Testing Reprieve

In addition to the Temporary Certificate for Visual Inspection requirements currently in development, CAAR and Fertilizer Canada have already submitted an application to Transport Canada for a Temporary Certificate asking for compliance reprieve for nurse and applicator tanks required to meet Section 5.10 (1) of the TDGR; Hydrostatic testing requirements in Specific Requirement 55 of the CSA B622-14 Standard. Negotiations with Transport Canada are ongoing. CAAR will send further information on the requested reprieve from Hydrostatic testing requirements as soon as it is available.
