191. A primary copper production plant must have systems that continuously measure and record
(1) the opacity or the concentration of the gas particles emitted into the atmosphere;
(2) the sulphur dioxide concentration and the flow of the gases emitted into the atmosphere; and
(3) sulphur dioxide in the atmosphere at not fewer than 5 sampling stations.
For the purposes of subparagraph 1 of the first paragraph, the emissions considered are those from sources not treated by a sulphuric acid plant referred to in the second paragraph of section 185.
A zinc production plant is subject to the continuous measuring requirements in subparagraph 2 of the first paragraph and the requirements in subparagraph 3 of the first paragraph for at least 2 sampling stations.
The sampling stations required for the purposes of subparagraph 3 of the first paragraph and the third paragraph must be situated in such manner as to be representative of the site where the concentration of contaminants emitted into the atmosphere is the highest.
This section applies to existing primary copper production plants and zinc production plants as of 30 June 2012, except subparagraph 1 of the first paragraph that applies to those plants as of 30 June 2013.
