Negligible sources of contaminant

8. (1) It is not necessary, when using an approved dispersion model for the purposes of this Part, to consider a source of contaminant that discharges a negligible amount of the relevant contaminant, having regard to,

(a) the total amount of the contaminant that is discharged by all the sources of contaminant with which the approved dispersion model is used; and

(b) the nature of the contaminant.

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:

1. A scenario that assumes operating conditions for the facility that would result, for the relevant contaminant, in the highest concentration of the contaminant at a point of impingement that the facility is capable of.

2. A scenario that 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.

(2) Despite subsection (1), the Director may give written notice to a person who discharges or causes or permits discharges of contaminants from a facility requiring the person to use an approved dispersion model for the purposes of this Part in accordance with the scenario described in paragraph 2 of subsection (1), if,

2. The emission rate is derived from site-specific testing of the source of contaminant that meets all of the following criteria:

i. The testing must be conducted comprehensively across a full range of operating conditions.

ii. The testing must be conducted according to a plan approved by the Director as likely to provide an accurate reflection of emissions.

iii. The Director must be given written notice at least 15 days before the testing and representatives of the Ministry must be given an opportunity to witness the testing.

(b) the relevant contaminant is not listed in any of Schedules 1, 2 and 3 and the use of the model indicates that discharges of the contaminant may cause an adverse effect,

the approved dispersion model shall be used in accordance with the scenario described in paragraph 2 of subsection 10 (1) and with emission rates determined in accordance with paragraph 2 or 3 of subsection 11 (1).

(2) Despite subsection (1), an approved dispersion model may be used in accordance with the scenario described in paragraph 1 of subsection 10 (1) or with emission rates determined in accordance with paragraph 1 of subsection 11 (1), but not with both, if,

(a) the model does not indicate that discharges of the relevant contaminant from the property may result in a contravention of section 18, 19 or 20; or

(b) the relevant contaminant is not listed in any of Schedules 1, 2 and 3 and the use of the model does not indicate that discharges of the contaminant may cause an adverse effect.

(3) This section does not apply to a contaminant if a written abatement plan for discharges of the contaminant from the property has been prepared and submitted to a provincial officer in accordance with section 29.

(3) Before the Director gives a person a notice under subsection (2), 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 30 days after the draft is given.

(4) This section applies only if the approved dispersion model is used with respect to a person and contaminant to which section 20 applies.

Area of modelling coverage

14. (1) Subject to subsections (2) and (3), an approved dispersion model that is used for the purposes of this Part shall be used in a manner that predicts the concentration of the relevant contaminant at points of impingement separated by intervals of,

(a) 20 metres or less, in an area that is bounded by a rectangle, where every point on the boundary of the rectangle is at least 200 metres from every source of contaminant;

(b) 50 metres or less, in an area that surrounds the area described in clause (a) and that is bounded by a rectangle, where every point on the rectangle is at least 300 metres from the area described in clause (a);
