or cause to be discharged to the atmosphere visible emissions in excess
of 10 percent opacity from any PM add-on air pollution control device if
a COM is chosen as the monitoring option.
(6) The owner or operator may determine the emission standards for a
SAPU by applying the group 1 furnace limits on the basis of the aluminum
production weight in each group 1 furnace, rather than on the basis of
feed/charge.
(7) The owner or operator of a sidewell group 1 furnace that
conducts reactive fluxing (except for cover flux) in the hearth, or that
conducts reactive fluxing in the sidewell at times when the level of
molten metal falls below the top of the passage between the sidewell and

the sidewell and the hearth.
(j) In-line fluxer. Except as provided in paragraph (j)(3) of this
section for an in-line fluxer using no reactive flux material, the owner
or operator of an in-line fluxer must use the limits in this paragraph
to determine the emission standards for a SAPU.

aluminum production facility that is a major source must not discharge
or cause to be discharged to the atmosphere visible emissions in excess
of 10 percent opacity from any PM add-on air pollution control device
used to control emissions from the in-line fluxer, if a COM is chosen as
the monitoring option.
(5) The owner or operator may determine the emission standards for a
SAPU by applying the in-line fluxer limits on the basis of the aluminum
production weight in each in-line fluxer, rather than on the basis of
feed/charge.
(k) Secondary aluminum processing unit. On and after the compliance
date established by Sec. 63.1501, the owner or operator must comply
with the emission limits calculated using the equations for PM and HCl
in paragraphs (k)(1) and (2) of this section for each secondary aluminum
processing unit at a secondary aluminum production facility that is a
major source. The owner or operator must comply with the emission limit
calculated using the equation for D/F in paragraph (k)(3) of this
section for each secondary aluminum processing unit at a secondary
aluminum production facility that is a major or area source.
(1) The owner or operator must not discharge or allow to be
discharged to the atmosphere any 3-day, 24-hour rolling average
emissions of PM in excess of:
[[Page 59]]
[GRAPHIC] [TIFF OMITTED] TR23MR00.000
Where,
LtiPM = The PM emission limit for individual emission unit i
in paragraph (i)(1) and (2) of this section for a group 1 furnace or in
paragraph (j)(2) of this section for an in-line fluxer;
Tti = The feed/charge rate for individual emission unit I;
and
LcPM = The PM emission limit for the secondary aluminum
processing unit.
Note: In-line fluxers using no reactive flux materials cannot be
included in this calculation since they are not subject to the PM limit.

discharged to the atmosphere any 3-day, 24-hour rolling average
emissions of HCl in excess of:
[GRAPHIC] [TIFF OMITTED] TR30DE02.001

LtiHCl = The HCl emission limit for individual emission unit
i in paragraph (i)(4) of this section for a group 1 furnace or in
paragraph (j)(1) of this section for an in-line fluxer; and
LcHCl = The HCl emission limit for the secondary aluminum
processing unit.
Note: In-line fluxers using no reactive flux materials cannot be
included in this calculation since they are not subject to the HCl
limit.
(3) The owner or operator must not discharge or allow to be
discharged to the atmosphere any 3-day, 24-hour rolling average
emissions of D/F in excess of:
[GRAPHIC] [TIFF OMITTED] TR23MR00.002
Where,
LtiD/F = The D/F emission limit for individual emission unit
i in paragraph (i)(3) of this section for a group 1 furnace; and
LcD/F = The D/F emission limit for the secondary aluminum
processing unit.
Note: Clean charge furnaces cannot be included in this calculation
since they are not subject to the D/F limit.
(4) The owner or operator of a SAPU at a secondary aluminum
production facility that is a major source may demonstrate compliance
with the emission limits of paragraphs (k)(1) through (3) of this
section by demonstrating that each emission unit within the SAPU is in
compliance with the applicable emission limits of paragraphs (i) and (j)
of this section.
(5) The owner or operator of a SAPU at a secondary aluminum
production facility that is an area source may demonstrate compliance
with the emission limits of paragraph (k)(3) of this section by
demonstrating that each emission unit within the SAPU is in compliance
with the emission limit of paragraph (i)(3) of this section.
(6) With the prior approval of the responsible permitting authority,
an owner or operator may redesignate any existing group 1 furnace or in-
line fluxer at a secondary aluminum production facility as a new
emission unit. Any emission unit so redesignated may thereafter be
included in a new SAPU at that facility. Any such redesignation will be
solely for the purpose of this MACT standard and will be irreversible.
