NR 463.166(2)(b)(b) The owner or operator of an emission unit subject to a D&F emission limit shall use Equation 7A to determine compliance with the emission limit in s. NR 463.13: where:
E is the emission rate of D&F, mg/Mg (gr/ton) of feed;
C is the concentration of D&F, mg/dscm (gr/dscf);

NR 463.166(3)(3) HCL percent reduction standard. The owner or operator of an emission unit subject to the HCl percent reduction standard shall use Equation 8 to determine compliance with the HCl percent reduction standard in s. NR 463.13: where:
%R is the percent reduction of the control device
Li is the inlet loading of pollutant, kg/Mg (lb/ton)
Lo is the outlet loading of pollutant, kg/Mg (lb/ton)
NR 463.166(4)(4) Conversion of D&F measurements to TEQ units. To convert D&F measurements to TEQ units, the owner or operator shall use the procedures and equations in Interim Procedures for Estimating Risks Associated with Exposures to Mixtures of Chlorinated Dibenzo-p-Dioxins and -Dibenzofurans (CDDs and CDFs) and 1989 Update (EPA-625/3-89-016), incorporated by reference in s. NR 484.05 (12). NR 463.166(5)(5) Secondary aluminum processing unit. The owner or operator of a secondary aluminum processing unit shall use the procedures in pars. (a) to (c) or the procedure in par. (d) to determine compliance with emission limits in s. NR 463.13 for a secondary aluminum processing unit. NR 463.166(5)(a)(a) Use Equation 9 to compute the mass-weighted PM emissions for a secondary aluminum processing unit. Compliance is achieved if the mass-weighted emissions for the secondary aluminum processing unit (EcPM) is less than or equal to the emission limit for the secondary aluminum processing unit (LcPM calculated using Equation 1 in s. NR 463.13 (11)). where:
is the mass-weighted PM emissions for the secondary aluminum processing unit is the measured PM emissions for individual emission unit i is the average feed rate for individual emission unit i during the operating cycle or performance test period n is the number of emission units in the secondary aluminum processing unit
NR 463.166(5)(b)(b) Use Equation 10 to compute the aluminum mass-weighted HCl emissions for the secondary aluminum processing unit. Compliance is achieved if the mass-weighted emissions for the secondary aluminum processing unit (EcHCl) is less than or equal to the emission limit for the secondary aluminum processing unit (LcHCl) calculated using Equation 2 in s. NR 463.13 (11). where:
