61. The updraft vertical exhaust velocity of combustion gas discharge into the atmosphere from equipment installed or put into operation after 14 November 1979, that has a rated power less than 3 MW, using wood or wood waste, wood or wood waste containing or saturated with formaldehyde-based glue or granules produced from lignocellulosic crops as fuel, alone or in combination with a fossil fuel, and whose combustion gases are discharged through a stack installed or built after that date, must be at least 10 m per second at the stack outlet, when the equipment is operating at its rated heat capacity.
The updraft vertical exhaust velocity of combustion gas discharge into the atmosphere from the following equipment must be at least 15 m per second at the stack outlet when the equipment is operating at its rated heat capacity or, where applicable, at its rated power:(1) fuel burning equipment, installed or put into operation after 14 November 1979, that uses heavy fuel oil and whose combustion gases are discharged through a stack installed or built on or after that date; and
(2) fuel burning equipment, installed or put into operation after 14 November 1979, that has a rated heat capacity equal to or greater than 3 MW, using a fuel referred to in Division IV or V of this Chapter, alone or in combination with a fossil fuel, and whose combustion gases are discharged through a stack installed or built after that date;
(3) (subparagraph revoked).
This section does not apply to fuel burning equipment using exclusively light fuel oil or fuel in a gaseous state at the feed point.
