Application 1.1 This Regulation does not apply with respect to motor gasoline that is reasonably expected to be transported for use or sale outside of Ontario. O. Reg. 533/22, s. 2. Summer Gasoline 2. (1) No person who owns or operates a bulk plant, service station or terminal shall cause or permit any motor gasoline to leave the bulk plant, service station or terminal in summer if the motor gasoline has a vapour pressure exceeding the volatility limit. O. Reg. 335/24, s. 2. (2) With respect to motor gasoline that is transported to the North, subsection (1) applies, (a) only in Northern summer; and (b) with the Northern volatility limit instead of the volatility limit. O. Reg. 335/24, s. 2. (3) A person who owns or operates a bulk plant or terminal and causes or permits motor gasoline to leave the bulk plant or terminal in summer shall comply with section 5 (Testing and Reporting). O. Reg. 335/24, s. 2. (4) This section does not apply in respect of motor gasoline at a bulk plant, service station or terminal unless, (a) the motor gasoline is provided to the bulk plant, service station or terminal directly from a refinery; or (b) the motor gasoline is imported to the bulk plant, service station or terminal directly from outside of Ontario. O. Reg. 335/24, s. 2. (5) For greater certainty, this section applies in respect of a bulk plant, service station or terminal whether or not the bulk plant, service station or terminal is located on the same site as a refinery. O. Reg. 335/24, s. 2. (6) Despite subsection (1), a person to whom subsection (1) applies may cause or permit motor gasoline that has a vapour pressure that exceeds the volatility limit to leave the bulk plant, service station or terminal during the period that begins on May 16 and ends on May 31 if it is done for the purpose of, (a) emptying the bulk plant, service station or terminal of motor gasoline that has a vapour pressure exceeding the volatility limit; or (b) transitioning the motor gasoline in the bulk plant, service station or terminal to gasoline that has a vapour pressure that does not exceed the volatility limit. O. Reg. 33/25, s. 1. 3. Revoked: O. Reg. 335/24, s. 3. Mixing 4. (1) No person shall, in late summer, cause or permit the mixing of or adding to gasoline or components of gasoline, such that the product is motor gasoline that has a vapour pressure exceeding the volatility limit. (2) No person who causes or permits the mixing of or adding to gasoline or components of gasoline shall, in late summer, cause or permit any of the motor gasoline product to leave the site where it was mixed or added to if it has a vapour pressure exceeding the volatility limit. O. Reg. 271/91, s. 4 (1, 2). (2.1) For the purposes of subsections (1) and (2), the Northern volatility limit applies instead of the volatility limit, (a) to motor gasoline that is transported to the North; and (b) in the North, so long as the motor gasoline is not transported to the Southern Ontario corridor. O. Reg. 45/97, s. 4 (1). (3) A person who, in late summer, causes or permits the mixing of or adding to gasoline or components of gasoline, such that the product is motor gasoline shall comply with section 5 (Testing and Reporting). O. Reg. 271/91, s. 4 (3). (4) Subsection (3) does not apply if the only mixing or adding to is the mixing of two or more motor gasolines and the person causing or permitting the mixing has reason to believe that none of such motor gasolines has a vapour pressure exceeding the volatility limit or the Northern volatility limit, as the case may be. O. Reg. 271/91, s. 4 (4); O. Reg. 45/97, s. 4 (2). (5) This section does not apply to a service station. O. Reg. 533/22, s. 3. Testing and Reporting 5. (1) The person required by section 2 or 4 to comply with this section shall cause the vapour pressure of every batch of motor gasoline described in those sections to be determined in accordance with a method referred to in section 6 and recorded by a laboratory, (a) which is accredited for the determination of vapour pressure by a laboratory accreditation program approved by the Director and sponsored by an organization under the auspices of the Standards Council of Canada; and (b) which both determines vapour pressure, subject to subsection (1.1), and makes a record of its determinations in a manner consistent with the accreditation program. O. Reg. 271/91, s. 5 (1); O. Reg. 533/22, s. 4 (1); O. Reg. 335/24, s. 4 (1, 2); O. Reg. 33/25, s. 2. (1.1) For the purposes of determining the vapour pressure of motor gasoline under subsection (1), if the determined vapour pressure is not a whole number, the vapour pressure must be rounded to the nearest whole number in accordance with the rounding method set out in ASTM E29, “Standard Practice for Using Significant Digits in Test Data to Determine Conformance with Specifications”, published by ASTM International, as it may be amended from time to time, and the vapour pressure must be recorded using that whole number. O. Reg. 533/22, s. 4 (2). (2) The person required by section 2 or 4 to comply with this section shall keep each record prepared under subsection (1) for at least five years. O.
