Equations for determining compliance

Equations for determining compliance. (1) THC emission limit. The owner or operator of an emission unit subject to a THC emission limit shall use Equation 6 to determine compliance with the THC emission limit in s. NR 463.13 : (2) PM, HCL and D&F emission limits. (a) The owner or operator of an emission unit subject to a PM or HCl emission limit shall use Equation 7 to determine compliance with the PM or HCl emission limit in s. NR 463.13 : (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 : (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 : (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) . (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. (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 (E cPM ) is less than or equal to the emission limit for the secondary aluminum processing unit (L cPM calculated using Equation 1 in s. NR 463.13 (11) ). (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 (E cHCl ) is less than or equal to the emission limit for the secondary aluminum processing unit (L cHCl ) calculated using Equation 2 in s. NR 463.13 (11) . (c) Use Equation 11 to compute the aluminum mass-weighted D&F emissions for the secondary aluminum processing unit. Compliance is achieved if the mass-weighted emissions for the secondary aluminum processing unit is less than or equal to the emission limit for the secondary aluminum processing unit. The emission limit for the secondary aluminum processing unit (L cD&F ) is calculated using Equation 3 in s. NR 463.13 (11) . (d) As an alternative to using the equations in pars. (a) to (c) , the owner or operator may demonstrate compliance for a secondary aluminum processing unit by demonstrating that each existing group 1 furnace is in compliance with the emission limits for a new group 1 furnace in s. NR 463.13 (9) and that each existing in-line fluxer is in compliance with the emission limits for a new in-line fluxer in s. NR 463.13 (10) .
