ALERT

Diesel Fuel in Non-Specification
Slip Tanks—Permit Expiring

by Zenon Lewycky

The Permit for Equivalent Level of Safety that granted an extension allowing use of non-specification tanks for transporting diesel, heating oil and Jet A fuel,¹ by road is expiring on January 1, 2005. Most tanks affected are the so-called ‘slip tanks’, mounted on pickup trucks or small trailers.

After January 1, 2005, all tanks of over 450L capacity, in use for transportation of these substances by road, must be in conformity with the Transportation of Dangerous Goods Regulations. Non-specification tanks may still be used until 2010, but only if they are qualified to Specific Requirement 5(b) of Standard CAN/CSA-B621-98.

To qualify under SR 5(b), the tank must be brought for inspection to a facility registered by Transport Canada for inspecting TC306 or TC406 tanks. The facility will perform a visual inspection as well as a leak and pressure test at 21 kPa (3psi).² If the results are satisfactory, the facility will attach a “non-specification flammable liquids tank” nameplate for identification. Non-specification tanks under SR 5(b) must also be periodically inspected following application of the non-specification nameplate. The periodic inspection includes an annual visual inspection and leak test at a Transport Canada registered facility. Tanks that are beyond their due date for inspection may not be refilled.

Slip tanks complying with ULC/ORD C142.13, manufactured before 2003, may be used until 2010 and they do not need the non-specification nameplate described above. They are, however, required to undergo the periodic inspections and tests for “mobile IBC’s” as prescribed under standard CAN/CGSB 43.146-2002. This includes internal and external visual inspection every 60 months. The 60-month period is counted from the date of manufacture or subsequent inspection.

Any slip tank built after January 1, 2003 must be a UN Standard Mobile IBC, as prescribed by the CAN/CGSB 43.146-2002 standard, if it is to be used for transport of flammable liquids.

Refer to the summary table on the next page for details on the various containers that are permitted for use in transport of gasoline and diesel fuel. For information on the registered tank inspection facilities in your area, please visit the TDG Web site at:
