§ 63.1513
THC emission limit.
Use Equation 6 to determine compliance with an emission limit for THC:
E = Emission rate of measured pollutant, kg/Mg (lb/ton) of feed;
C = Measured volume fraction of pollutant, ppmv;
MW = Molecular weight of measured pollutant, g/g-mole (lb/lb-mole): THC (as propane) = 44.11;
K1 = Conversion factor, 1 kg/1,000 g (1 lb/lb);
K2 = Conversion factor, 1,000 L/m3 (1 ft3/ft3);
Mv = Molar volume, 24.45 L/g-mole (385.3 ft3/lb-mole); and
PM, HCl and D/F emission limits.
Use Equation 7 of this section to determine compliance with an emission limit for PM or HCl:
Use Equation 7A of this section to determine compliance with an emission limit for D/F:
HCl percent reduction standard.
Use Equation 8 to determine compliance with an HCl percent reduction standard:
%R = Percent reduction of the control device;
Li = Inlet loading of pollutant, kg/Mg (lb/ton); and
Lo = Outlet loading of pollutant, kg/Mg (lb/ton).
Conversion of D/F measurements to TEQ units.
To convert D/F measurements to TEQ units, the owner or operator must 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 § 63.1502 of this subpart, available from the National Technical Information Service (NTIS), 5285 Port Royal Road, Springfield, Virginia, NTIS no. PB 90-145756.
Use the procedures in paragraphs (e)(1), (2), and (3) or the procedure in paragraph (e)(4) of this section to determine compliance with emission limits for a secondary aluminum processing unit.
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 § 63.1505(k).
EcPM = The mass-weighted PM emissions for the secondary aluminum processing unit;
EtiPM = Measured PM emissions for individual emission unit i;
Tti = The average feed rate for individual emission unit i during the operating cycle or performance test period; and
n=The number of emission units in the secondary aluminum processing unit.
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 § 63.1505(k).
EcHCl = The mass-weighted HCl emissions for the secondary aluminum processing unit; and
EtiHCl = Measured HCl emissions for individual emission unit i.
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 (LcD/F) calculated using Equation 3 in § 63.1505(k).
EcD/F = The mass-weighted D/F emissions for the secondary aluminum processing unit; and
EtiD/F = Measured D/F emissions for individual emission unit i.
As an alternative to using the equations in paragraphs (e)(1), (2), and (3) of this section, 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 § 63.1505(i) and that each existing in-line fluxer is in compliance with the emission limits for a new in-line fluxer in § 63.1505(j).
