(1) For the Act, section 128(1), the point at which the standard of concentration, or rate of emission, of air impurities resulting from the carrying on of an activity, or the operation of plant, on premises must not be exceeded is the point between—

(a) the point of origin of the air impurities, that is—

(i) the point where the air impurities originate, or

(ii) if the air impurities subsequently pass through control equipment—the point where the air impurities emerge from that equipment, and

(b) the point of release of the air impurities, that is—

(i) the point where the air impurities pass into the atmosphere, or

(ii) if air, gas or vapour is added to the air impurities before that point after passing through control equipment—the point immediately before the point where the air, gas or vapour is added.

(2) If there is more than 1 point of release applying in relation to an activity or plant, a reference in subsection (1) to the point of release is a reference to all of the points of release applying in relation to the activity or plant.
