Version 3.0 Created June 10, 2020

Preamble

  • This technical standard is an industry standard as defined in section 1 of O. Reg. 419/05.
  • With respect to facilities, this industry standard applies to every facility that is part of a class identified by NAICS code: 325110 (Petrochemical Manufacturing).
  • With respect to contaminants, this industry standard applies to contaminants listed in Appendix 7-A.
  • Each source of contaminant associated with NAICS code 325110 that discharges a contaminant mentioned in the above bullet has been considered in development of this industry standard. As such, a person that meets the criteria set out in subsection 42 (1) or subsection 44 (1) of O. Reg. 419/05 is, in general, exempt from Part II of the Regulation in respect of the facility and contaminant(s) for which it is registered. In other words, there is no need to model, in a facility’s Emission Summary and Dispersion Modelling report, discharges of a registered contaminant from any source of contaminant associated with NAICS code 325110. (For more information, please see the Introduction to the Technical Standards Publication.)
  • In accordance with subsection 38 (3) of O. Reg. 419/05, compliance with this industry standard, in accordance with subsection 42 (5) or subsection 44 (3) of O. Reg. 419/05, may reduce the regulatory burden applicable to facilities in this class.
  • This standard contains requirements that relate to sources of contaminant associated with the following:
    • storage vessels
    • equipment leaks
    • sewage treatment operations
    • truck and railcar product loading racks and marine vessel loading berths
  • For this industry standard, with respect to benzene, the publication of this industry standard indicates that the following criteria of paragraph 3 of subsection 38 (1) of O. Reg. 419/05 are met:
    1. with respect to at least two facilities located in Ontario to which this standard applies, it is not technically feasible to comply with section 20 of O. Reg. 419/05; and
    2. compliance, in accordance with subsection 42 (5) of O. Reg. 419/05, with this standard,
      1. is technically and economically feasible with respect to at least one facility located in Ontario to which this industry standard applies,
      2. will permit efforts that would otherwise be made to comply with section 19 or 20 of O. Reg. 419/05 to be put to better use to protect the natural environment, having regard to clause (a), and
      3. including this industry standard in the “Technical Standards to Manage Air Pollution” is more efficient than having the Director consider separate requests under section 32 of O. Reg. 419/05 to set site-specific standards for the contaminant that would otherwise apply to facilities in the class.
