Questions and Answers on the Federal Sulphur in Gasoline Regulations

Questions on Sections of the Regulations

Section 1: Interpretation

  1. Can an officer of a corporation delegate a senior official of the corporation to act on his/her behalf for the purposes of being an "authorized official"?

    No. If the primary supplier is a corporation, the regulations require that an officer of the corporation sign the relevant forms.

  2. Why does the definition of "gasoline" have two parts?

    The first part of the definition means that any fuel generally sold or represented as gasoline is treated as gasoline for the purposes on the regulations. This part of the definition will usually suffice to distinguish whether or not a fuel is gasoline. The second part of the definition has measurable physical properties, and can be used to distinguish gasoline from other fuels to cover circumstances where the fuel is not readily identifiable as "gasoline".

    Note that a fuel is considered to be gasoline under the regulations if it meets either of the parts of the definition; the fuel is not required to meet both parts.

  3. Why does the definition of "gasoline" include sub-octane gasoline (i.e., a "road" octane of less than 86)?

    The second part of the definition of gasoline includes a specification for the antiknock index (the average of Research and Motor octane number and often referred to as road octane). The lowest antiknock index allowed in Canada under the Canadian General Standards Board for unleaded automotive gasoline is 86. At the request of industry, the definition of "gasoline" includes a limit at 80. This is to allow refiners, importers and blenders the flexibility to produce or import unfinished gasoline destined for subsequent blending at a downstream facility as "gasoline-like blendstock" (see below).

  4. What is "gasoline-like blendstock"?

    "Gasoline-like blendstock" is a fuel meeting either parts of the definition for gasoline which is intended to be further refined or blended to produce low-sulphur gasoline and has been identified as gasoline-like blendstock by the primary supplier under section 5. The concept of gasoline-like blendstock provides flexibility to dispatch or to import unfinished gasoline intended to be subsequently blended at a downstream blending facility. The requirements for gasoline-like blendstock are set out in section 6 of the regulations.

  5. What is the difference between "pool average" in the Sulphur in Gasoline Regulations and "yearly pool average" as defined in the Benzene in Gasoline Regulations?

    Under the Sulphur in Gasoline Regulations, during the first 2½ years, primary suppliers have the option of meeting an average limit for sulphur over the entire 2½-year period. The term "pool average" has therefore been used in these regulations.

    Under the Benzene in Gasoline Regulations, primary suppliers must meet the average limits for benzene and BEN each year. Hence, "yearly pool average" is used in those regulations.

  6. What is "low-sulphur gasoline"?

    "Low-sulphur gasoline" is gasoline that meets the compositional requirements of the regulations and is identified as low-sulphur gasoline by the primary supplier under section 5 of the regulations.

  7. Why does "scientific research" exclude marketing research?

    Scientific research means research that furthers scientific understanding. It includes research into the physical and chemical characteristics of gasoline and their effects on vehicles, the health of people, the environment, etc. It does not include any research undertaken by or for the seller of the gasoline into the preferences of the consumer or any type of market research.

  8. What are "sulphur-limited oxygenate" and "sulphur-limited butane"?

    Sulphur-limited oxygenate and sulphur-limited butane are oxygenate and butane that do not exceed the contaminate sulphur levels specified by the regulations. These maximum sulphur contaminate levels are (in % by weight):

    Commercially pure butane

    Comercially pure oxygenate

    Until January 1, 2005



    On and after January 1, 2005



    The limits prior to January 1, 2005 are the same as those specified in the Benzene in Gasoline Regulations for commercial oxygenate and commercial butane. Those levels were set based on recommendations from industry. The later set of limits are the same as the flat limit for sulphur in gasoline set in the Sulphur in Gasoline Regulations.

  9. What do I need to do if I blend gasoline with an oxygenate or butane that does not meet the applicable contaminate levels?

    Any person who blends an oxygenate or butane that does not meet the applicable contaminate levels with low-sulphur gasoline or any other type of gasoline is considered a primary supplier. Therefore, this person must comply with the requirements placed upon a primary supplier by the regulations.

  10. Why is "year" defined differently for the year 2002?

    Since the compositional requirements do not come into force until July 1, 2002, the pool average for 2002 is computed using only gasoline supplied during the last half of the year. Therefore the definition of "year" has been written so that the last half of 2002 is treated as a year.
