Q-2, r. 4.1 - Clean Air Regulation

Section 90 Disposition versions

2012-09-01

90. The use in fuel burning equipment of fuel other than fuel referred to in Divisions III and IV of this Chapter is also subject to the following emission limits and other standards:

(1)  the fuel burning equipment must have a rated heat capacity or rated power, as the case may be, equal to or greater than 3 MW, subject to the use of biogas or granules produced from lignocellulosic crops and, in the case of used oil, to the provisions of section 26 of the Regulation respecting hazardous materials (chapter Q-2, r. 32);

(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 consecutive minutes.

That limit value may however be exceeded if the features of the fuel burning equipment 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 limit of 0.15% by weight of total halogens at the feed point;

(4)  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 organic compounds are present in the fuel used. The contaminant concentration in the combustion gases is obtained by adding the concentrations of each of the congeners listed in Schedule I and multiplying the sum obtained by the corresponding toxicity equivalency factor listed in that Schedule; and

(5)  a destruction and removal efficiency equal to or greater than 99.99% for each of the following substances:

(a)  any organic compound in fuel consisting of a residual hazardous material that 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.

The contaminant concentration measured pursuant to this section is expressed on a dry basis corrected to 7% oxygen according to the formula referred to in the first paragraph of section 79.

Despite the foregoing, the contaminant concentration measured pursuant to subparagraph 4 of the first paragraph is expressed on a dry basis corrected to 11% oxygen according to the formula referred to in the second paragraph of section 79.

For the purposes of this section, destruction and removal efficiency is calculated using the following formula:

---

Ed = (Qi - Qs) x 100
    _________

        Qi
        

where

“Ed” is the destruction and removal efficiency of the organic compound concerned;

“Qi” is the feed rate expressed in kg/h of the most thermally stable organic compound concerned by the prescribed destruction and removal efficiency; and

“Qs” is the rate of emission into the atmosphere of the organic compound referred to “Qi” that is present in the gases emitted, expressed in kg/h.

---

Subparagraphs 2, 4 and 5 of the first paragraph do not apply to biogas or granules produced from lignocellulosic crops or used oil used in accordance with the second paragraph of section 26 of the Regulation respecting hazardous materials.

In addition, subparagraph 5 of the first paragraph does 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.
