186. A primary copper production plant must not emit mercury into the atmosphere in excess of the limit of 2 g/t of anodes produced in the case of an existing plant, or in excess of the limit of 0.2 g/t of anodes produced in the case of a new plant.
For the purposes of this section, mercury emissions are calculated by the sum of the emissions from the reactor, converters and anode furnaces. Emissions are calculated on an annual basis in grams of mercury per ton of copper anodes produced.
