Additional obligations to prepare ESDM report
 24. (1) The Director may give a person written notice requiring the person to prepare a report in accordance with section 26 and to submit the report to the Director, not later than a date specified in the notice, if the Director has reasonable grounds to believe that, (a) the person may contravene section 19 or 20; (b) the person discharges or causes or permits the discharge of a contaminant into the air and the discharge may cause an adverse effect; or (c) the person discharges or causes or permits discharges of a contaminant into the air from two or more different sources of contaminant, the sources of contaminant are all located on the same property, and the person has never prepared a report in accordance with section 26 or a report that the Director considers equivalent to a report prepared in accordance with section 26.  O. Reg. 419/05, s. 24 (1); O. Reg. 516/07, s. 18 (1); O. Reg. 507/09, s. 23 (1). (1.1) A notice given under subsection (1) that requires a report to be prepared in accordance with section 26 may provide that the lists of contaminants required by paragraphs 2 and 4 of subsection 26 (1) only need to include contaminants specified in the notice.  O. Reg. 516/07, s. 18 (2). (2) If a notice is given under subsection (1) to a person to whom section 19 applies in respect of a contaminant, (a) the notice may require that the report be prepared as if section 20 applied instead of section 19 and, in that case, section 20 shall be deemed to apply for the purpose of preparing the report; or (b) the notice may require that the report be prepared so that, in addition to setting out the information required by this Regulation based on the application of section 19, the report contain a part that sets out the information that would be required by this Regulation if section 20 applied and, in that case, section 20 shall be deemed to apply for the purpose of preparing that part of the report.  O. Reg. 516/07, s. 18 (3); O. Reg. 507/09, s. 23 (2-4). (2.1) If a notice is given under subsection (1) and the notice includes a requirement referred to in clause (2) (a) or (b), the notice may also require that the report include the following in accordance with the notice: 1. A written statement or map identifying the location of any point of impingement where the use of the approved dispersion model indicates that discharges of the contaminant may result in a contravention of section 19 or 20 or cause an adverse effect. 2. A written statement specifying the highest concentration of the contaminant that the approved dispersion model predicts for the point of impingement. 3. A written statement specifying the number of averaging periods for which the approved dispersion model predicts that discharges of the contaminant may result in a contravention of section 19 or 20 or cause an adverse effect 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. 18 (3); O. Reg. 507/09, s. 23 (5, 6). (2.2) Subsection (2.1) does not apply if a notice is given under subsection (1), the notice includes a requirement referred to in clause (2) (a) or (b) and the notice requires that the report include the following in accordance with the notice: 1. A written statement or map identifying the location of points of impingement specified in the notice. 2. A written statement specifying the concentration of the contaminant that the approved dispersion model predicts at points of impingement specified in the notice. 3. A written statement specifying the number of averaging periods for which the approved dispersion model predicts that discharges of the contaminant may result in a contravention of section 19 or 20 or cause an adverse effect because of the concentration of the contaminant at points of impingement specified in the notice, 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. 18 (3); O. Reg. 507/09, s. 23 (7). (2.3) A person who is required to prepare a report under subsection (1) that includes the information referred to in subsection (2.1) or (2.2) 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. 23 (8). (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 (2.1) or (2.2), as the case may be.  O. Reg. 516/07, s. 18 (3); O. Reg. 507/09, s. 23 (8). (3) Before the Director gives a person a notice under subsection (1), 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 15 days after the draft is given.  O. Reg. 419/05, s. 24 (3). (4) If, for the purpose of preparing a report required by this section, a person is required under subsection 10 (2) or 12 (1) to use an approved dispersion model in accordance with the scenario described in paragraph 2 of subsection 10 (1), the person shall also use the model in accordance with the scenario described in paragraph 1 of subsection 10 (1).  O. Reg. 507/09, s. 23 (9).
