(2) The ASHRAE method of calculation may be used for the purposes of this Part with respect to a contaminant only with respect to a point of impingement that is located on the same structure as the source of contaminant. O. Reg. 516/07, s. 5. Operating conditions 10. (1) An approved dispersion model that is used for the purposes of this Part shall be used in accordance with one of the following scenarios for each averaging period applicable to the relevant contaminant: 1. A scenario that, for the relevant averaging period, assumes operating conditions for the facility that would result in the highest concentration of the contaminant at a point of impingement that the facility is capable of. 2. A scenario that, for the relevant averaging period, uses actual operating data for the facility for the occasion when the highest concentration of the contaminant at a point of impingement resulted during, i. the year preceding the year in which the model is being used, or ii. the year in which the model is being used, if the facility did not operate at any time during the year referred to in subparagraph i. O. Reg. 516/07, s. 6 (1); O. Reg. 507/09, s. 8 (1); O. Reg. 109/18, s. 3 (1). (1.1) If a facility is part of a class identified by NAICS code 324190 or 324110, in addition to being used in accordance with one of the scenarios mentioned in subsection (1), an approved dispersion model that is used for the purposes of this Part shall be used with respect to the discharge of sulphur dioxide from the facility in accordance with the scenario that, for a one-hour averaging period, assumes operating conditions for the facility that would result in the highest concentration of sulphur dioxide at a point of impingement that the facility is capable of when acid gas is flaring at the facility. O. Reg. 109/18, s. 3 (2). (1.2) In order to determine, for the purposes of subsection (1.1), which scenario will result in the highest concentration of sulphur dioxide at a point of impingement, only scenarios composed of one or more of the following types of scenarios shall be considered: 1. A scenario that assumes operating conditions that can occur when no sulphur recovery unit at the facility is operating and the flare system is receiving the mass flow rate of sulphur that would otherwise have been processed by all of the sulphur recovery units at the facility. 2. Any other scenario that can occur at the facility when acid gas is flaring at the facility. O. Reg. 109/18, s. 3 (2). (1.3) For the purposes of paragraph 1 of subsection (1.2), the mass flow rate of sulphur corresponds to the lower of, (a) the maximum combined processing capacity of all sulphur recovery units at the facility; and (b) the maximum combined processing capacity imposed by law, if any, of all of the sulphur recovery units at the facility. O. Reg. 109/18, s. 3 (2). (1.4) The Director may, by written notice, require a person making a determination for the purposes of subsection (1.1) to consider a scenario specified in the notice if the scenario is a type of scenario mentioned in subsection (1.2) and the Director is of the opinion that the specified scenario may result in the highest concentration of sulphur dioxide at a point of impingement that a facility is capable of when acid gas is flaring at the facility. O. Reg. 109/18, s. 3 (2). (1.5) In order to determine, for the purposes of paragraph 1 of subsection (1), which scenario would result in the highest concentration of the relevant contaminant at a point of impingement that a facility is capable of, only scenarios composed of one or more of the following types of scenarios shall be considered: 1. Scenarios that assume operating conditions that can occur when the operation of the facility or part of the facility is being increased from an inoperative state to normal operating conditions. 2. Scenarios that assume operating conditions that can occur when the operation of the facility or part of the facility is being decreased from normal operating conditions to an inoperative state. 3. Scenarios that assume operating conditions that can occur when the facility or part of the facility is operating at its maximum design capacity. 4. Subject to subsection (1.6), any other scenario that assumes operating conditions that can occur at the facility. O. Reg. 109/18, s. 3 (2). (1.6) The reference in paragraph 4 of subsection (1.5) to “any other scenario” does not include a scenario that assumes operating conditions that would occur if the facility or part of the facility were to fail to operate in a normal manner. O. Reg. 109/18, s. 3 (2). (1.7) For greater certainty, an operating condition mentioned in subsection (1.6) may be designed to occur or not designed to occur. O. Reg. 109/18, s. 3 (2).

(1) The Director may approve a request under section 32 and set a site-specific standard for the contaminant that is the subject of the request if, (a) the person making the request has complied with sections 32 to 34.1; and (b) the Director is of the opinion that, (i) the person making the request cannot comply with section 20 with respect to the standard set out in Schedule 3 for the contaminant for the averaging period specified under paragraph 0.1 of subsection 33 (1) because, (A) it is not technically feasible for the person to comply, in the case of a person who is relying on any paragraph of subsection 32 (1), or (B) it is not economically feasible for the person to comply, in the case of a person who is relying on a paragraph of subsection 32 (1) other than paragraph 4, (ii) the difference between the standard set out in Schedule 3 for the contaminant for the averaging period specified in paragraph 0.1 of subsection 33 (1) and the site-specific standard set by the Director for the contaminant is the minimum difference necessary to enable the person to comply with section 20 with respect to the contaminant, and (iii) there is no public interest reason sufficient to require the denial of the request. O. Reg. 507/09, s. 32 (1); O. Reg. 282/11, ss. 10 (1-4). (2) Despite subsection (1), the Director shall not approve a request under section 32 to set a site-specific standard for a contaminant if the contaminant is listed in Schedule 6 and the Director is of the opinion that the site-specific standard is likely to permit discharges of the contaminant that too frequently result in the concentration of the contaminant at a point of impingement located on a place referred to in subsection 30 (8) exceeding the other time period upper risk threshold set out for the contaminant in Schedule 6. O. Reg. 507/09, s. 32 (1); O. Reg. 282/11, s. 10 (5). (3) The Director shall not approve or refuse to approve a request under section 32 unless the Director first gives the person making the request a draft of the approval or refusal and an opportunity to make written submissions to the Director during the period that ends 30 days after the draft is given. O. Reg. 507/09, s. 32 (1). (3.1) If the Director approves a request under section 32 and sets a site-specific standard, the approval shall specify that the standard applies only to the averaging period specified under paragraph 0.1 of subsection 33 (1).

(9.1) If an amendment to Schedule 3 that has not yet come into force sets out a standard for a contaminant, and a site-specific standard set by the Director applies to the same contaminant and the same averaging period, the period specified by the Director under subsection (9) shall not begin earlier than the date the amendment comes into force unless specifically requested by the person making the request. O. Reg. 282/11, s. 10 (10). (10) Subsection (9) does not prevent the making of further requests under section 32 in respect of the contaminant but, in considering a further request, the Director may consider the number of previous requests that have been made for the source of contaminant that is the subject of the request. O. Reg. 507/09, s. 32 (1). (11) If a site-specific standard for a contaminant is set by the Director under this section and a further request is made under section 32 in respect of the contaminant, subsections 32 (6) to (11) do not apply. O. Reg. 507/09, s. 32 (1, 6); O. Reg. 282/11, s. 10 (11). (12) The Director shall consider the following matters when he or she decides whether to impose conditions under subsection (6), what those conditions should be, and what period to specify under subsection (9): 1. The nature of the contaminant. 2. The frequency with which the inability to comply with section 20 referred to in subclause (1) (b) (i) would occur. 3.

Transition 37.1 (1) If, before the day this section came into force, the Director approved a request under section 32 to alter a standard set out in Schedule 3, the altered standard shall be deemed, for the purposes of this Regulation, to be a site-specific standard set by the Director. O. Reg. 282/11, s. 13. (2) If, before the day this section came into force, a person made a request under section 32 to alter a standard set out in Schedule 3 and the request was not approved or refused by the Director before that day, the Director shall consider the request as if it were a request for a site-specific standard and, for that purpose, the person who made the request shall be deemed, under paragraph 0.1 of subsection 33 (1), to have specified the averaging period of the standard set out in Schedule 3 that was the subject of the request. O. Reg. 282/11, s. 13. Technical Standards for Classes of Facilities Technical Standards publication 38. (1) The Minister shall ensure that, with respect to the Technical Standards publication, all of the following criteria are met: 1. Every technical standard set out in the Technical Standards publication is specifically identified in the publication as an industry standard or an equipment standard. 2. For each industry standard that is set out in the Technical Standards publication, i. the Technical Standards publication specifies which classes of facilities the industry standard applies to, and those classes are identified with reference to NAICS codes, ii. the Technical Standards publication specifies which contaminants the industry standard applies to, iii. the Technical Standards publication sets out the steps that shall be taken to comply with the industry standard, and iv. the Technical Standards publication sets out the time periods, if any, within which the steps specified under subparagraph iii shall be taken. 3. The Technical Standards publication indicates that, with respect to each class specified under subparagraph 2 i to which an industry standard applies, and with respect to at least one contaminant to which that standard applies, the Minister is of the opinion that, i. with respect to at least two facilities in the class that are located in Ontario, A. it is not technically feasible to comply with section 19 or 20, whichever is applicable, or B. it is not economically feasible to comply with section 19 or 20, whichever is applicable, ii. compliance, in accordance with subsection 42 (5), with the industry standard that applies to the class and the contaminant, A. is technically and economically feasible with respect to at least one facility in the class that is located in Ontario, and B. will permit efforts that would otherwise be made to comply with section 19 or 20 to be put to better use to protect the natural environment, having regard to subparagraph i, iii. including the industry standard that applies to the class and the contaminant in the Technical Standards publication is more efficient than having the Director consider separate requests under section 32 to set site-specific standards for the contaminant that would otherwise apply to facilities in the class. 4. For each equipment standard that is set out in the Technical Standards publication, i. the Technical Standards publication specifies which classes of facilities the equipment standard applies to, and those classes are identified with reference to NAICS codes, ii. the Technical Standards publication specifies which contaminants the equipment standard applies to, iii. the Technical Standards publication specifies which sources of contaminant the equipment standard applies to, iv. the Technical Standards publication sets out the steps that shall be taken to comply with the equipment standard, and v. the Technical Standards publication sets out the time periods, if any, within which the steps specified under subparagraph iv shall be taken. 5. The Technical Standards publication indicates that, with respect to each class specified under subparagraph 4 i to which a equipment standard applies and with respect to at least one contaminant and source of contaminant to which that standard applies, the Minister is of the opinion that, i. at least two facilities in the class that are located in Ontario have the source of contaminant, and ii. compliance, in accordance with subsection 43 (4), with the equipment standard that applies to the class, the contaminant and the source of contaminant is technically and economically feasible with respect to at least one facility in the class that is located in Ontario. O. Reg. 507/09, s. 32 (1); O. Reg. 282/11, s. 14. (2) Before a technical standard is set out in the Technical Standards publication, the Minister shall consider whether provisions dealing with the following matters should be included in the technical standard: 1. Notification of and consultation with affected persons before making an application for registration in respect of the technical standard. 2. The making and retention of records. 3. Circumstances in which notice is required to be given to the Ministry. 4. Progress reports relating to implementation of the technical standard. O. Reg. 507/09, s. 32 (1). (3) Before an industry standard that applies to a class of facilities is set out in the Technical Standards publication, the Minister shall consider whether compliance, in accordance with subsection 42 (5), with the industry standard may reduce the regulatory burden applicable to facilities in that class for which compliance with section 19 or 20 would otherwise be required. O. Reg. 507/09, s. 32 (1). (4) Before an equipment standard that applies to a class of facilities and a source of contaminant is set out in the Technical Standards publication, the Minister shall consider whether compliance, in accordance with subsection 43 (4), with the equipment standard may reduce the regulatory burden applicable to facilities in that class for which consideration of the source of contaminant would otherwise be necessary when using an approved dispersion model for the purposes of this Part. O. Reg. 507/09, s. 32 (1). Registration 39. (1) A person may apply to the Director for registration in the Ministry’s Technical Standards Registry – Air Pollution in respect of, (a) an industry standard, facility and contaminant; or (b) an equipment standard, facility, contaminant and source of contaminant.
