2. This Regulation applies to every source of atmospheric contamination, subject to the following cases:
(1)  in the case of bituminous concrete plants, only the fuel sulphur content standards set out in section 57, the combustion gas discharge velocity standards set out in section 61, the standards that apply to the use of a fuel referred to in Division V of Chapter VI of Title II and the air quality standards referred to in section 197 apply;
(2)  in the case of quarries and sandpits, only the emission opacity standards set out in section 16, the fuel sulphur content standards set out in section 57, the combustion gas discharge velocity standards set out in section 61, the standards that apply to the use of a fuel referred to in Division V of Chapter VI of Title II and the air quality standards referred to in section 197 apply;
(3)  in the case of production equipment subject to the provisions of Chapter III of the Regulation respecting pulp and paper mills (chapter Q-2, r. 27), only the emission opacity standards set out in section 16, the fugitive particle emission standards set out in Division III of Chapter II of Title II, the fuel sulphur content standards set out in section 57, subparagraphs 1 and 2 of the first paragraph and subparagraph 1 of the second paragraph of section 58, the combustion gas discharge velocity standards set out in section 61, the standards that apply to the use of a fuel referred to in Division V of Chapter VI of Title II and the air quality standards referred to in section 197 apply;
(4)  in the case of flour mills and other grain processing facilities whose production is not commercialized or whose drying capacity does not exceed 15 tons per hour, only the emission opacity standards set out in section 16, the fugitive particle emission standards set out in Division III of Chapter II of Title II, the fuel sulphur content standards set out in section 57 and the air quality standards referred to in section 197 apply;
(5)  in the case of fuel burning systems used for domestic heating, only the fuel sulphur content standards set out in section 57 apply.
Subject to the first paragraph, the emission standards referred to in section 9 apply to every source of contamination other than the facilities referred to in sections 132 and 138 for which no specific particle emission standards are determined under this Regulation or any other regulation made under the Environment Quality Act (chapter Q-2).
In the event that the provisions of this Regulation are inconsistent with those of any other Regulation made under the Environment Quality Act, the provisions that ensure greater protection of the environment are to prevail.
The provisions of this Regulation also apply in a reserved area or an agricultural zone established under the Act respecting the preservation of agricultural land and agricultural activities (chapter P-41.1).
