92. An industrial furnace using fuel other than fuel referred to in Divisions III and IV of this Chapter must not emit particles into the atmosphere in excess of the emission limits prescribed by Chapter IX of Title II for that type of industrial furnace or, in other cases, in excess of the limits prescribed by Chapter II of Title II.
The use in an industrial furnace of fuel other than that referred to in Divisions III and IV of this Chapter is subject to the following emission limits and other standards:
(1) the furnace must have a rated heat capacity equal to or greater than 3 MW, subject in the case of used oil to section 26 of the Regulation respecting hazardous materials (chapter Q-2, r. 32); and
(2) an emission limit of 114 mg/Rm3 of dry gas for carbon monoxide calculated as the running average of the emissions over a period of 60 minutes.
That limit value may however be exceeded if the features of the industrial furnace used do not allow compliance with that limit, provided the total hydrocarbon concentration, calculated according to the running average of the emissions during a period of 60 minutes, remains equal to or less than 20 ppm, expressed as propane on a dry basis, in combustion gases. The limit value of the carbon monoxide then applicable is established on the basis of the results obtained during burning tests and calculated according to the average of the highest running averages of the carbon monoxide emissions during a period of 60 minutes, obtained for each burning test;
(3) a destruction and removal efficiency equal to or greater than 99.9999% for each of the following substances contained in the fuel if the fuel consists of a residual hazardous material or is fuel if its total halogen content at the feed point is greater than 0.15% by weight:
(a) any halogenated organic compound in a concentration such that the fuel containing it at the feed point is a toxic material;
(b) any halogenated organic compound if the total halogen content in the fuel containing it at the feed point is greater than 0.15% by weight; and
(c) any PCB if the total PCB concentration in the fuel containing it at the feed point is greater than 50 mg/kg;
(4) a destruction and removal efficiency equal to or greater than 99.99% for each of the following substances:
(a) any organic compound, other than those referred to in subparagraph 3 of the second paragraph, in fuel consisting of a residual hazardous material or in fuel if its total halogen content at the feed point is greater than 0.15% by weight and would be a hazardous material if it were the sole component of the fuel; and
(b) any halogenated organic compound present in a gaseous effluent used as fuel and originating from a process;
(5) if the fuel used contains a contaminant listed in Schedule G, the furnace must not emit such a contaminant into the atmosphere in such manner that its concentration in the atmosphere exceeds the concentration prescribed by that Schedule according to an air dispersion model in accordance with Schedule H; and
(6) an emission limit of 0.08 ng/Rm3 of dry gas for polychlorinated dibenzofuran and polychlorinated dibenzo [b,e] [1,4] dioxin congeners if chlorinated compounds are present in the fuel used. The calculation of the contaminant concentration must take into account the toxicity equivalency factors listed in Schedule I.
Subparagraphs 2 to 6 of the second paragraph do not apply to the use of used oil as fuel in accordance with the second paragraph of section 26 of the Regulation respecting hazardous materials.
In addition, subparagraph 2 of the second paragraph does not apply to
(1) clinker kilns;
(2) lime kilns;
(3) furnaces of bituminous concrete plants using used oils whose contaminant content complies with the standards provided for in Schedule 6 to the Regulation respecting hazardous materials;
(4) furnaces with a destruction and removal efficiency prescribed by this Regulation that is equal to or greater than 99.9999%; or
(5) furnaces using carbon monoxide or hydrogen as fuel, alone or in combination with non combustible compounds.
For the purposes of subparagraphs 3 and 4 of the second paragraph, the destruction and removal efficiency is calculated using the formula in the fourth paragraph of section 90.
Subparagraphs 3 and 4 of the second paragraph do not apply to fuel consisting exclusively of used oil that has a contaminant content meeting the standards in Schedule 6 to the Regulation respecting hazardous materials.
