81.The use as fuel of wood or wood waste containing one of the contaminants referred to in section 78 is permitted only in fuel burning equipment or an industrial furnace with a rated power or rated heat capacity equal to or greater than 3 MW that has a destruction and removal efficiency equal to or greater than 99.99% for each of the following substances:
(1) pentachlorophenol; and
(2) each of the organic compounds present as a result of creosote treatment and which would be a hazardous material if the compound were the sole component of the fuel.
For the purposes of this section, destruction and removal efficiency is calculated using the following formula:
Ed = (Qi - Qs) x 100 _________
“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 of the organic compound concerned by “Qi” that is present in the gases emitted, expressed in kg/h.
