NR 463.12(43) (43) “Total reactive chlorine flux injection rate” means the sum of the total weight of chlorine in the gaseous or liquid reactive flux and the total weight of chlorine in the solid reactive chloride flux, divided by the total weight of feed or charge, as determined by the procedure in s. NR 463.163 (16)

NR 463.13 NR 463.13 Emission standards for affected sources and emission units.

NR 463.13(1) (1) Summary. The owner or operator of a new or existing affected source shall comply with each applicable limit in this section. The following table summarizes the emission standards for each type of source:

Table 1

Emission Standards for New and Existing Affected Sources

- See PDF for table

Table 1 (Continued)

Emission Standards for New and Existing Affected Sources

- See PDF for table

a D&F limit applies to a unit at a major or area source.

b Sweat furnaces equipped with afterburners meeting the specifications of s. NR 463.13 (6) are not required to conduct a performance test.

c These limits are also used to calculate the limits applicable to secondary aluminum processing units.

d Equation definitions:

  LiPM is the PM emission limit for individual emission unit i in the secondary aluminum processing unit [kg/Mg (lb/ton) of feed]

  Ti is the feed rate for individual emission unit i in the secondary aluminum processing unit

  LtPM is the overall PM emission limit for the secondary aluminum processing unit [kg/Mg (lb/ton) of feed]

  LiHCl is the HCl emission limit for individual emission unit i in the secondary aluminum processing unit [kg/Mg (lb/ton) of feed]

  LtHCl is the overall HCl emission limit for the secondary aluminum processing unit [kg/Mg (lb/ton) of feed]

  Li D&F is the D&F emission limit for individual emission unit i [mg TEQ/Mg (gr TEQ/ton) of feed]

  Lt D&F is the overall D&F emission limit for the secondary aluminum processing unit [mg TEQ/Mg (gr TEQ/ton) of feed]

  n is the number of units in the secondary aluminum processing unit

e In-line fluxers using no reactive flux materials cannot be included in this calculation since they are not subject to the PM limit.

f In-line fluxers using no reactive flux materials cannot be included in this calculation since they are not subject to the HCl limit.

g Clean charge furnaces cannot be included in this calculation since they are not subject to the D&F limit.

NR 463.13(2) (2) Aluminum scrap shredder. On and after the compliance date established by s. NR 463.115, the owner or operator of an aluminum scrap shredder at a secondary aluminum production facility that is a major source may not discharge or cause to be discharged to the atmosphere either of the following:

NR 463.13(2)(a) (a) Emissions in excess of 0.023 grams of PM per dry standard cubic meter (0.010 grain of PM per dry standard cubic foot).

NR 463.13(2)(b) (b) Visible emissions in excess of 10% opacity from any PM add-on air pollution control device if a continuous opacity monitor (COM) or visible emissions monitoring is chosen as the monitoring option.

NR 463.13(3) (3) Thermal chip dryer. On and after the compliance date established by s. NR 463.115, the owner or operator of a thermal chip dryer may not discharge or cause to be discharged to the atmosphere emissions in excess of either of the following:
