Section 28: Threshold assessments for control areas

(1) Without limiting the general effect of this Part, the Authority shall, in collaboration with the relevant lead agencies, undertake threshold assessments for control areas to ensure that the level of pollutants in ambient and in-door air quality are not exceeded, in compliance with Schedule 2 and Schedule 6 to these Regulations. (2) For the purposes of subregulation (1) and to minimise risk to human health arising from exposure to pollutants, the Authority and the relevant lead agencies shall, in accordance with management plans developed under regulation 23, establish thresholds of ambient and indoor air quality standards that shall not be exceeded in control areas. (3) For the purposes of these Regulations, control areas are- (a) residential areas; (b) hospitals; (c) universities, tertiary institutions, schools and other educational centres; (d) passenger carrying spaces and stations (terminals) of air, rail and road transport; (e) national parks, wildlife reserves and sanctuaries; (f) conservation areas; (g) central business districts; and (h) any other areas as may be determined by the Authority. (4) The Authority may, in collaboration with the relevant lead agency, periodically review the list of control areas set out in subregulation (3) where there are significant changes in the activities which may affect the levels of pollutants in ambient and indoor air.
