(a) Subsections (b)
						and (c) apply to all processes except combustion units, incinerators and pulp
						mill smelt dissolving tanks.
(b) No
						person may permit the emission into the outdoor atmosphere of particulate
						matter from a process listed in the following table, at any time, either in
						excess of the rate calculated by the formula in paragraph (2) or in a manner
						that the concentration of particulate matter in the effluent gas exceeds .02
						grains per dry standard cubic foot, whichever is greater:

Formula.
A = .76E0.42
where:
A = Allowable emissions in pounds per hour.
E = Emission index = F X W pounds per hour.
F = Process factor in pounds per unit, and
W = Production or charging rate in units per
						  hour.
The factor F shall be obtained from the table in
						  paragraph (1). The units for F and W shall be compatible.
(3)
Allowable emissions.
Allowable emissions under this subsection are graphically indicated in Appendix
						B.
