Notice to provincial officer as a result of modelling or measurements
 28. (1) A person who discharges or causes or permits the discharge of a contaminant shall, as soon as practicable, notify a provincial officer in writing if, (a) the person uses an approved dispersion model to predict concentrations of the contaminant that result from the discharges and, (i) the use of the model indicates that discharges of the contaminant may result in a contravention of section 19 or 20, or (ii) sections 19 and 20 do not apply to discharges of the contaminant and the use of the model indicates that discharges of the contaminant may cause an adverse effect; (b) measurements of air samples indicate that discharges of the contaminant may result in a contravention of section 19 or 20; or (c) sections 19 and 20 do not apply to discharges of the contaminant and measurements of air samples indicate that discharges of the contaminant may cause an adverse effect.  O. Reg. 419/05, s. 28 (1); O. Reg. 516/07, s. 23 (1, 2); O. Reg. 507/09, s. 28 (1-4). (1.1) The Director may give written notice to a person who discharges or causes or permits the discharge of a contaminant requiring the person to notify a provincial officer in writing, at regular intervals specified by the Director, of any circumstances described in clause (1) (a), (b) or (c).  O. Reg. 605/05, s. 7 (1). (1.1.1) Before the Director gives a person a notice under subsection (1.1), 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. 516/07, s. 23 (3). (1.2) Subsection (1) does not apply to a person who complies with a notice given by the Director under subsection (1.1).  O. Reg. 605/05, s. 7 (1). (2) If a person is required to give notice under subsection (1) or (1.1) of circumstances described in clause (1) (a) and, according to the approved dispersion model, 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 a point of impingement, the Director may give the person a written notice requiring the person to provide the Director with the following in accordance with the notice: 1. A written statement or map identifying the location of the point of impingement. 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. 419/05, s. 28 (2); O. Reg. 605/05, s. 7 (2); O. Reg. 516/07, s. 23 (4-6); O. Reg. 507/09, s. 28 (5, 6). (2.1) If subsection (2) authorizes the Director to give a person a notice, the Director may instead give the person a written notice requiring the person to provide the Director with 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. 23 (7); O. Reg. 507/09, s. 28 (7). (2.2) If a notice requires a person to provide the Director with information referred to in subsection (2) or (2.1), the person shall provide the information using, (a) the AERMOD dispersion model described in paragraph 1 of subsection 6 (1); or (b)  Revoked: O. Reg. 507/09, s. 28 (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) or (2.1), as the case may be.  O. Reg. 516/07, s. 23 (7); O. Reg. 507/09, s. 28 (8). (3) If a person is required to give notice under subsection (1) or (1.1) of circumstances described in clause (1) (b) or (c) and, according to measurements of air samples collected at a point of impingement, 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, the Director may give the person a written notice requiring the person to provide the Director in writing with the following in accordance with the notice: 1. A written statement or map identifying the location of the point of impingement. 2. A written statement specifying the number of air samples that were collected at the point of impingement and measured for the contaminant. 3. A written 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 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 air samples referred to in paragraph 2.  O. Reg. 419/05, s. 28 (3); O. Reg. 605/05, s. 7 (3); O. Reg. 516/07, s. 23 (8); O. Reg. 507/09, s. 28 (9, 10).
