Upper risk thresholds
 30. (1) A person who discharges or causes or permits the discharge of a contaminant listed in Schedule 6 into the air shall comply with subsections (3) and (4) if there is reason to believe, based on any relevant information, that discharges of the contaminant may result in the concentration of the contaminant exceeding, (a) the half hour upper risk threshold set out for that contaminant in Schedule 6 at a point of impingement, if section 19 applies to the person in respect of the contaminant; or (b) the other time period upper risk threshold set out for that contaminant in Schedule 6 at a point of impingement, if section 20 applies to the person in respect of the contaminant.  O. Reg. 516/07, s. 24 (1); O. Reg. 507/09, s. 30 (1); O. Reg. 109/18, s. 8. (1.1) The two items in Schedule 6 that set out upper risk thresholds for total reduced sulphur (TRS) compounds specify the facilities to which they apply.  O. Reg. 516/07, s. 24 (1). (2) Without limiting the generality of subsection (1), the reference in that subsection to relevant information includes relevant information from predictions of a dispersion model, including, (a) an approved dispersion model or other dispersion model; or (b) a dispersion model that is not used in accordance with this Regulation.  O. Reg. 419/05, s. 30 (2). (3) If subsection (1) applies to a discharge, the person who discharged or caused or permitted the discharge of the contaminant shall immediately notify the Director in writing.  O. Reg. 419/05, s. 30 (3). (4) If subsection (1) applies to a discharge, the person who discharged or caused or permitted the discharge of the contaminant shall, within three months after the discharge, prepare a report in accordance with section 26 and submit the report to the Director.  O. Reg. 419/05, s. 30 (4). (5) If a person is required to prepare a report under subsection (4) and section 20 does not apply to the person in respect of the contaminant, section 20 shall be deemed to apply for the purpose of preparing the report and for the purpose of subsections (7) and (8).  O. Reg. 419/05, s. 30 (5). (5.1) A person who prepares a report required by subsection (4) shall prepare the report using, (a) the AERMOD dispersion model described in paragraph 1 of subsection 6 (1); or (b)  Revoked: O. Reg. 507/09, s. 30 (2). (c) a dispersion model or combination of dispersion models that, (i) pursuant to subsection 7 (3), is deemed to be included in references in this Part to approved dispersion models, and (ii) is capable of providing the information referred to in subsection (7).  O. Reg. 516/07, s. 24 (2); O. Reg. 507/09, s. 30 (2). (5.2) Despite subsections 10 (1) and (2), a person who prepares a report required by subsection (4) shall use an approved dispersion model in accordance with both of the scenarios described in subsection 10 (1).  O. Reg. 507/09, s. 30 (3). (6) Paragraphs 1, 1.1, 2 and 2.1 of subsection 13 (1) do not apply to a person who prepares a report required by subsection (4) unless meteorological data described in paragraphs 3 and 4 of subsection 13 (1) is not available and cannot reasonably be available in time to prepare the report within the three-month period referred to in subsection (4).  O. Reg. 419/05, s. 30 (6); O. Reg. 516/07, s. 24 (3). (6.1) If a report is required by subsection (4) to be prepared in accordance with section 26, it is not necessary for the lists of contaminants required by paragraphs 2 and 4 of subsection 26 (1) to include any contaminant other than the contaminant in respect of which the Director must be notified under subsection (3).  O. Reg. 516/07, s. 24 (4). (6.2) A person who is required to prepare a report under subsection (4) shall ensure that the table required by paragraph 14 of subsection 26 (1) contains the following additional information: 1. The other time period upper risk threshold set out for the contaminant in Schedule 6. 2. A comparison of the concentration referred to in subparagraph 14 v of subsection 26 (1) and the other time period upper risk threshold set out for the contaminant in Schedule 6, expressed as a percentage of the threshold.  O. Reg. 516/07, s. 24 (4). (7) If, according to an approved dispersion model that is used for the purpose of preparing a report under subsection (4), discharges of a contaminant may result in a contravention of section 20 because of the concentration of the contaminant at a point of impingement located on a place referred to in subsection (8), the person who prepares the report shall include the following in the report: 1. A statement or map identifying the place that the point of impingement is located on. 2. A statement specifying the highest concentration of the contaminant that the approved dispersion model predicts for the point of impingement. 3. A statement specifying the number of averaging periods for which the approved dispersion model predicts that discharges of a contaminant may result in a contravention of section 20 because of the concentration of the contaminant at the point of impingement, expressed as a percentage of the number of averaging periods in, i. a period of five years, if the approved dispersion model was used in accordance with meteorological data described in paragraph 1, 1.1, 2 or 2.1 of subsection 13 (1), ii. a period equal to the length of the period over which the meteorological data was collected, if the approved dispersion model was used in accordance with local or site-specific meteorological data described in paragraph 3 of subsection 13 (1), or iii. a period equal to the length of the period that was used for the purposes of the computational method, if the approved dispersion model was used in accordance with meteorological data obtained from a computational method in accordance with paragraph 4 of subsection 13 (1).  O. Reg. 516/07, s. 24 (5). (8) The following places are the places referred to in subsection (7) and in subsection 35 (2): 1. A health care facility. 2. A senior citizens’ residence or long-term care facility. 3. A child care facility. 4. An educational facility. 5. A dwelling. 6. A place specified by the Director in a notice under subsection (9) as a place where discharges of a contaminant may cause a risk to human health.  O. Reg. 419/05, s. 30 (8); O. Reg. 507/09, s. 30 (4). (9) For the purpose of paragraph 6 of subsection (8), the Director may give written notice to a person who is required to notify the Director under subsection (3) stating that the Director is of the opinion that the discharge may cause a risk to human health at a place specified in the notice.  O. Reg. 419/05, s. 30 (9). (10) Before the Director gives a person a notice under subsection (9), the Director shall give the person a draft of the notice and an opportunity to make written submissions to the Director during the period that ends five business days after the draft is given.  O. Reg. 419/05, s. 30 (10). (11) If, according to measurements of air samples collected at a point of impingement, discharges of a contaminant may result in a contravention of section 19 or 20 because of the concentration of the contaminant at the point of impingement, a person who prepares a report under subsection (4) shall include in the report, (a) a statement or map identifying the place that the point of impingement is located on; (b) a statement specifying the number of air samples that were collected at the point of impingement and measured for the contaminant; and (c) a statement specifying the number of air samples that were collected at the point of impingement and measured for the contaminant and that indicated that discharges of the contaminant may result in a contravention of section 19 or 20 because of the concentration of the contaminant at the point of impingement, expressed as a percentage of the number of air samples referred to in clause (b).  O. Reg. 419/05, s. 30 (11); O. Reg. 507/09, s. 30 (5, 6). (12) Subsection (4) does not apply if the Director is satisfied that discharges of the contaminant will not result in a contravention of section 19 or 20 and will not cause an adverse effect.  O. Reg. 419/05, s. 30 (12); O. Reg. 507/09, s. 30 (7). (13) Subsection (4) does not apply if, (a) a report in accordance with section 26 that relates to the contaminant is already required to be submitted to the Director within the three-month period referred to in subsection (4); or (b) a report that relates to the contaminant has previously been submitted to the Director under subsection (4) and the Director is satisfied that another report is not necessary.  O. Reg. 605/05, s. 9. (14) Subsections (3) and (4) do not apply if the reason to believe referred to in subsection (1) is based on predictions of a dispersion model that is used in the preparation of a report under subsection (4).  O. Reg. 605/05, s. 9.
