72. Fuel burning equipment referred to in any of sections 64 to 67 with a rated heat capacity equal to or greater than 15 MW must have a sampling system that continuously measures and records the particle concentration or opacity of the gases emitted into the atmosphere as well as the oxygen, carbon monoxide and nitrogen oxide concentration.
However, if such equipment is supplied exclusively with gaseous fuel or is supplied with liquid fossil fuel less than 500 hours per year, the opacity and particle concentration in the gases emitted need not be measured and recorded by the system.
The nitrogen oxide concentration, the opacity and the particle concentration need not be measured and recorded by the system where the fuel burning equipment is in operation less than 500 hours per year.
For the purposes of this section, for the measurement and recording of the particle concentration or opacity of the gases emitted into the atmosphere, all fuel burning equipment is considered to be a single unit of equipment emitting gases through a single stack.
This section applies to existing fuel burning equipment as of 30 June 2013.
