Benzene in gasoline regulations

These regulations prohibit the supply of gasoline with a benzene concentration exceeding 1.0% by volume or a benzene emission number exceeding 71 during the summer and 92 during the winter. They also prohibit the sale of gasoline that contains a benzene concentration exceeding 1.5% by volume.

The Benzene in Gasoline Regulations include provisions that allow for alternative samples or analysis methods to be used by a primary supplier for reporting purposes. A primary supplier proposing to use an equivalent test methods 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. Where the sampling or analysis methods being used at a site have been demonstrated as equivalent methods pursuant to section 6 of the Benzene in Gasoline Regulations, those methods can be also be used for reporting purposes under the Sulphur in Gasoline Regulations.

The following table summarizes the methods for which equivalency for reporting purposes has been demonstrated. Those proposing to use these methods for reporting under the Benzene in Gasoline Regulations and Sulphur in Gasoline Regulations may refer to this information in respect to the evidence of equivalency requirements of section 6 of the Regulations:

Benzene emissions number calculation spreadsheet

The model for calculating benzene emission numbers is prescribed in Schedule 1 of the regulations. Environment and Climate Change Canada has developed a calculation spreadsheet for the benzene emissions number. For a copy of the spreadsheet, please contact Environment and Climate Change Canada at: ec.carburants-fuels.ec@canada.ca
