• 2. (1) These Regulations do not apply to diesel fuel if

  • (a) the fuel is in transit through Canada, from a place outside Canada to another place outside Canada, and is accompanied by written evidence establishing that the fuel is in transit;

  • (b) the fuel is produced or sold for export and is accompanied by written evidence establishing that the fuel will be exported;

  • (c) the fuel is being imported for a use referred to in section 3, the fuel’s sulphur concentration exceeds the concentration referred to in that section and the fuel is accompanied by written evidence establishing that the fuel will meet the requirements of these Regulations before the fuel is used or sold; or

  • (d) the fuel is being imported in a fuel tank that supplies an off-road engine, a small stationary engine, a large stationary engine or the engine of a conveyance that is used for transportation by water, land or air.

• (2) These Regulations, except for section 1, subsections 5(4) to (7) and sections 5.2 and 6, do not apply in respect of diesel fuel for use in scientific research.

• 3. (1) For the purposes of section 139 of the Act and subject to subsection (2), the concentration of sulphur shall not exceed,

  • (a) in diesel fuel produced, imported or sold for use in on-road vehicles or off-road engines, 15 mg/kg;

  • (b) in diesel fuel produced or imported for use in locomotive engines or in vessel engines other than those installed on a vessel propelled by a large diesel engine, 15 mg/kg;

  • (c) in diesel fuel sold for use in locomotive engines, 500 mg/kg;

  • (d) in diesel fuel sold for use in vessel engines other than those installed on a vessel propelled by a large diesel engine, 500 mg/kg until May 31, 2014 and 15 mg/kg after May 31, 2014;

  • (e) in diesel fuel produced, imported or sold for use in vessel engines installed on a vessel propelled by a large diesel engine, 1000 mg/kg after May 31, 2014;

  • (f) in diesel fuel produced, imported or sold for use in small stationary engines, 15 mg/kg after May 31, 2014; and

  • (g) in diesel fuel produced, imported or sold for use in large stationary engines, 1000 mg/kg after May 31, 2014.

• (2) Paragraphs (1)(f) and (g) do not apply in respect of diesel fuel that is produced, imported or sold for use north of latitude 81°N.

4. The concentration of sulphur in diesel fuel referred to in section 3 shall be measured in accordance with the ASTM International method ASTM D5453-09, Standard Test Method for Determination of Total Sulfur in Light Hydrocarbons, Spark Ignition Engine Fuel, Diesel Engine Fuel, and Engine Oil by Ultraviolet Fluorescence.
