The operator of a steel mill with a production capacity equal to or greater than 5,000 ton per year must, at least once a year, take samples of the gases at the stack or at the emission point into the atmosphere from the scrubbers connected to the furnace and, every 3 years, take samples of the gases from the building housing the furnaces, calculate the rate or concentration, as the case may be, of the contaminants to which this Division applies, and for that purpose, measure each of the parameters necessary for the calculation and determination of the applicable limit.
The operator must also take the first sample and calculation of the gases from the building housing the furnaces within 2 years as of 30 June 2011 in the case of an existing plant or, in the case of a new plant, within 1 year as of the date on which it is put into operation.
The operator of a steel mill with a production capacity equal to or greater than 5,000 ton per year carrying out the activities referred to in section 150 must, at least once every 5 years, take samples of the gases at the emission point into the atmosphere of the local ventilation system, calculate the particle emission rate, and for that purpose, measure each of the parameters necessary for the calculation.
