Table 7.3 Proposed Action and Limit Levels for Impact Monitoring

Parameter	Action Level ^(1)	Limit Level
TSP (24 hour average)	· BL £ 200 mg m^-3, AL = (BL * 1.3 + LL)/2 · BL > 200 mg m^-3, AL = LL	260 mg m^-3
TSP (1 hour average)	· BL £ 384 mg m^-3, AL = (BL * 1.3 + LL)/2 · BL > 384 mg m^-3,AL = LL	500 mg m^-3

BL = Baseline level, AL = Action level, LL = Limit level.
