Sulphur in Diesel Fuel Regulations
The regulations set maximum limits for sulphur in diesel fuel for use on-road, off-road, in rail (locomotive), marine vessels, and stationary engines. The current maximum sulphur limits and effective dates for production, import and sales of diesel fuel in Canada are available in the compliance promotion information package for the federal fuels regulations. The goals of the regulations are to reduce air pollutant emissions and to ensure that the level of sulphur in diesel fuel used in Canada will not impede the effective operation of advanced emission control technologies installed on vehicles and engines.

The Sulphur in Diesel Fuel Regulations include provisions that allow for alternative analysis methods to be used for reporting under Schedule 1. Each person who wishes to use an equivalent test method for reporting purposes must provide, to Environment and Climate Change Canada (ECCC), at least 60 days’ notice before using the method, a description of the method and evidence that it is equivalent to the reference method, referred to in section 4 of the Regulations. Equivalency of the desired method must be validated in accordance with ASTM D6708-16, and the method is to be used for reporting purposes only. It shall not be used to determine compliance with the sulphur concentration requirements referred to in section 3 of the Regulations. The requirements may be found in section 5 of the Regulations.
The following table summarizes the methods for which equivalency for reporting purposes has been demonstrated. Those who wish to use these methods for reporting under the Regulations may refer to this information; however, a notice must still be submitted to ECCC at least 60 days before using one or more of the following methods:
Reference method: ASTM D5453
Sulphur - ASTM D2622
Sulphur (2 to 500 ppm) - ASTM D7039
Sulphur (6 to 50 mg/kg) - ASTM D7220
Sulphur (100 to 5 000 ppm) - CAN/CGSB-3.0 No. 16.0
