78. If the wood or wood waste used as fuel has been treated with a product containing creosote or pentachlorophenol, the fuel burning equipment must have a rated power equal to or greater than 3 MW and must not emit into the atmosphere(1) carbon monoxide in a concentration that exceeds the limit of 114 mg/Rm3 of dry gas calculated on the running average of the emissions taken over a period of 60 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 taken over a period of 60 minutes, remains equal to or less than 20 ppm, expressed as propane on a dry basis, in the combustion gases. The limit value of 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 emissions of carbon monoxide taken over a period of 60 minutes, obtained for each burning test;
(2) particles in a concentration that exceeds the limit prescribed by paragraph 1 of section 77.
In addition, if the wood or wood waste used as fuel has been treated with a product containing pentachlorophenol, the fuel burning equipment must not emit polychlorinated dibenzofurans or polychlorinated dibenzo [b,e] [1,4] dioxins into the atmosphere in excess of the limit of 0.08 ng/Rm3 of dry gas; 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.
