Sec.  63.1501(b) if no initial performance test is required. The plan
must be accompanied by a written certification by the owner or operator
that the OM&M plan satisfies all requirements of this section and is
otherwise consistent with the requirements of this subpart. The owner
or operator must comply with all of the provisions of the OM&M plan as
submitted to the permitting authority, unless and until the plan is
revised in accordance with the following procedures. If the permitting
authority determines at any time after receipt of the OM&M plan that
any revisions of the plan are necessary to satisfy the requirements of
this section or this subpart, the owner or operator must promptly make
all necessary revisions and resubmit the revised plan. If the owner or
operator determines that any other revisions of the OM&M plan are
necessary, such revisions will not become effective until the owner or
operator submits a description of the changes and a revised plan
incorporating them to the permitting authority. The owner or operator
must not begin operating under the revised plan until approval is
received or until after 60 days, whichever is sooner. Each plan must
contain the following information:
* * * * *
    (5) Procedures for monitoring process and control device
parameters, including lime injection rates, procedures for annual
inspections of afterburners, and if applicable, the procedure to be
used for determining charge/feed (or throughput) weight if a
measurement device is not used.
* * * * *
    (9) Procedures to be followed when changing furnace classification
under the provisions of Sec.  63.1514.
* * * * *
    (d) * * *
    (2) Inspect each capture/collection and closed vent system at least
once each calendar year to ensure that each system is operating in
accordance with the operating requirements in Sec.  63.1506(c) and
record the results of each inspection. This inspection shall include a
volumetric flow rate measurement taken at a location in the ductwork
downstream of the hoods which will be representative of the actual
volumetric flow rate without the interference of leaks, the
introduction of ambient air for cooling, or other ducts manifolded from
other hoods. The measurement shall be performed using EPA Reference
Methods 1 and 2 in appendix A to 40 CFR part 60.
* * * * *
    (f) * * *
    (1) * * *
    (ii) Each bag leak detection system must be installed, calibrated,
operated, and maintained according to the manufacturer's operating
instructions.
* * * * *
    (i) * * *
    (4) At least once per month, verify that the lime injection rate in
pound per hour (lb/hr) is no less than 90 percent of the lime injection
rate used to demonstrate compliance during your performance test.
    (j) * * *
    (4) Calculate and record the total reactive flux injection rate for
each operating cycle or time period used in the performance test using
the procedure in Sec.  63.1512(o). For solid flux that is added
intermittently, record the amount added for each operating cycle or
time period used in the performance test using the procedures in Sec.
63.1512(o).
* * * * *
    (n) * * *
    (1) Record in an operating log for each tap of a sidewell furnace
whether the level of molten metal was above the top of the passage
between the sidewell and hearth during reactive flux injection, unless
the furnace hearth was also equipped with an add-on control device. If
visual inspection of the molten metal level is not possible, the molten
metal level must be determined using physical measurement methods.
    (2) Submit a certification of compliance with the operational
standards in Sec.  63.1506(m)(6) for each 6-month reporting period.
Each certification must contain the information in Sec.
63.1516(b)(2)(iii).

    (o) * * *
    (1) The owner or operator must develop, in consultation with the
responsible permitting authority, a written site-specific monitoring
plan. The site-specific monitoring plan must be submitted to the
permitting authority as part of the OM&M plan. The site-specific
monitoring plan must contain sufficient procedures to ensure continuing
compliance with all applicable emission limits and must demonstrate,
based on documented test results, the relationship between emissions of
PM, HCl (and, for uncontrolled group 1 furnaces, HF), and D/F and the
proposed monitoring parameters for each pollutant. Test data must
establish the highest level of PM, HCl (and, for uncontrolled group 1
furnaces, HF), and D/F that will be emitted from the furnace. This may
be determined by conducting performance tests and monitoring operating
parameters while charging the furnace with feed/charge materials
containing the highest anticipated levels of oils and coatings and
fluxing at the highest anticipated rate. If the permitting authority
determines that any revisions of the site-specific monitoring plan are
necessary to meet the requirements of this section or this subpart, the
owner or operator must promptly make all necessary revisions and
resubmit the revised plan to the permitting authority.
* * * * *
    (ii) The permitting authority will review and approve or disapprove
a proposed plan, or request changes to a plan, based on whether the
plan contains sufficient provisions to ensure continuing compliance
with applicable emission limits and demonstrates, based on documented
test results, the relationship between emissions of PM, HCl (for
uncontrolled group 1 furnaces, HF) and D/F and the proposed monitoring
parameters for each pollutant. Test data must establish the highest
level of PM, HCl (for uncontrolled group 1 furnaces, HF) and D/F that
will be emitted from the furnace. Subject to permitting agency approval
of the OM&M plan, this may be determined by conducting performance
tests and monitoring operating parameters while charging the furnace
with feed/charge materials containing the highest anticipated levels of
oils and coatings and fluxing at the highest anticipated rate.

paragraph (u) of this section, the owner or operator must calculate and
record the 3-day, 24-hour rolling average emissions of PM, HCl (for
uncontrolled group 1 furnaces, HF) and D/F for each secondary aluminum
processing unit on a daily basis. To calculate the 3-day, 24-hour
rolling average, the owner or operator must:
* * * * *
    (2) * * *
    (i) Where no performance test has been conducted, for a particular
emission unit, because the owner of operator has, with the approval of
the permitting authority, chosen to determine the emission rate of an
emission unit by testing a representative unit, in accordance with
Sec.  63.1511(f), the owner of operator shall use the emission rate
determined from the representative unit in the SAPU emission rate
calculation required in Sec.  63.1510(t)(4).
    (ii) If the owner or operator has not conducted performance tests
for HCl and HF for an uncontrolled group 1 furnace or for HCL for an
in-line fluxer, in accordance with the provisions of Sec.
63.1512(d)(3), (e)(3), or (h)(2), the calculation required in Sec.
63.1510(t)(4) to determine SAPU-wide HCl and HF emissions shall be made
under the assumption that all chlorine-containing reactive flux added
to the emission unit is emitted as HCl and all fluorine-containing
reactive flux added to the emission unit is emitted as HF.
* * * * *
    (4) Compute the 24-hour daily emission rate using Equation 4:
    [GRAPHIC] [TIFF OMITTED] TP14FE12.037

Where:

Eday = The daily PM, HCl, D/F and, for uncontrolled group
1 furnaces, HF emission rate for the secondary aluminum processing
unit for the 24-hour period;
Ti = The total amount of feed, or aluminum produced, for
emission unit i for the 24-hour period (tons or Mg);
ERi = The measured emission rate for emission unit i as
determined in the performance test (lb/ton or [micro]g/Mg of feed/
charge); and
n = The number of emission units in the secondary aluminum
processing unit.

    (5) Calculate and record the 3-day, 24-hour rolling average for
each pollutant each day by summing the daily emission rates for each
pollutant over the 3 most recent consecutive days and dividing by 3.
The SAPU is in compliance with an applicable emission limit if the 3-
day, 24-hour rolling average for each pollutant is no greater than the
applicable SAPU emission limit determined in accordance with Sec.
63.1505(k)(1)-(3).

    g. Adding paragraph (g)(5) to read as follows:

Sec.  63.1511  Performance test/compliance demonstration general
requirements.

    (a) Site-specific test plan. Prior to conducting any performance
test required by this subpart, the owner or operator must prepare a
site-specific test plan which satisfies all of the requirements, and
must obtain approval of the plan pursuant to the procedures, set forth
in Sec.  63.7(c). Performance tests shall be conducted under such
conditions as the Administrator specifies to the owner or operator
based on representative performance of the affected source for the
period being tested. Upon request, the owner or operator shall make
available to the Administrator such records as may be necessary to
determine the conditions of performance tests.
    (b) Initial performance test. Following approval of the site-
specific test plan, the owner or operator must demonstrate initial
compliance with each applicable emission, equipment, work practice, or

operational standard for each affected source and emission unit, and
report the results in the notification of compliance status report as
described in Sec.  63.1515(b). The owner or operator of any existing
affected source for which an initial performance test is required to
demonstrate compliance must conduct this initial performance test no
later than the date for compliance established by Sec.  63.1501(a). The
owner or operator of any new affected source for which an initial
performance test is required must conduct this initial performance test
within 180 days after the date for compliance established by Sec.
63.1501(b). Except for the date by which the performance test must be
conducted, the owner or operator must conduct each performance test in
accordance with the requirements and procedures set forth in Sec.
63.7(c). Owners or operators of affected sources located at facilities
which are area sources are subject only to those performance testing
requirements pertaining to D/F. Owners or operators of sweat furnaces
meeting the specifications of Sec.  63.1505(f)(1) are not required to
conduct a performance test.
    (1) The performance tests must be conducted with the scrap
containing the highest level of contamination, at the highest rate of
production and using the highest reactive fluxing rate while an air
pollution control device is operating. Any subsequent performance tests
for the purposes of establishing new or revised parametric limits shall
be allowed upon pre-approval from the permitting authorities as
specified in the site-specific test plan. These new parametric settings
shall be used to demonstrate compliance for the period being tested.
* * * * *
    (6) Apply paragraphs (b)(1) through (5) of this section for each
pollutant separately if a different production rate, charge material
or, if applicable, reactive fluxing rate would apply and thereby result
in a higher expected emissions rate for that pollutant.
    (c) * * *
    (9) Method 26A for the concentration of HCl and HF. Where a lime-
injected fabric filter is used as the control device to comply with the
90-percent reduction standard, the owner or operator must measure the
fabric filter inlet concentration of HCl at a point before lime is
introduced to the system.
* * * * *
    (f) * * *
    (6) All 3 separate runs of a performance test must be conducted on
the same unit.
    (g) * * *
    (5) If the owner or operator wants to conduct a new performance
test and establish different operating parameter values, they must meet
the requirements in paragraphs (g)(1) through (4) of this section and
submit a revised site specific test plan and receive approval in
accordance with paragraph (a) of this section.
* * * * *

    a. Revising paragraph (e)(1);
    b. Revising paragraph (e)(2);
    c. Revising paragraph (e)(3);
    d. Adding paragraphs (e)(4);
    e. Adding paragraphs (e)(5);
    f. Revising paragraph (h)(1);

    i. Revising paragraph (j)(1)(i);
    j. Revising paragraph (j)(2)(i);
    k. Revising paragraph (o)(1);
    l. Revising paragraph (p)(2) to read as follows:

Sec.  63.1512  Performance test/compliance demonstration requirements
and procedures.

* * * * *
    (e) * * *
    (1) If the group 1 furnace processes other than clean charge
material, the owner or operator must conduct emission tests to measure
emissions of PM, HCl, HF, and D/F.
    (2) If the group 1 furnace processes only clean charge, the owner
or operator must conduct emission tests to simultaneously measure
emissions of PM, HCl and HF. A D/F test is not required. Each test must
be conducted while the group 1 furnace (including a melting/holding
furnace) processes only clean charge.
    (3) The owner or operator may choose to determine the rate of
reactive flux addition to the group 1 furnace and assume, for the
purposes of demonstrating compliance with the SAPU emission limit, that
all reactive flux added to the group 1 furnace is emitted. Under these
circumstances, the owner or operator is not required to conduct an
emission test for HCl or HF.
    (4) When testing an existing uncontrolled furnace, the owner or
operator must comply with the requirements of either paragraph
(e)(4)(i) or paragraph (e)(4)(ii) of this section at the next required
performance test.
    (i) Install hooding that meets ACGIH Guidelines, or
    (ii) Assume a 67-percent capture efficiency for the furnace exhaust
(i.e., multiply emissions measured at the furnace exhaust outlet by
1.5) if hooding does not meet ACGIH Guidelines. If the source fails to
demonstrate compliance using the 67-percent capture efficiency
assumption, the owner or operator must re-test with a hood that meets
the ACGIH Guidelines within 90 days, or petition the permitting
authority that such hoods are impracticable and propose testing
procedures that will minimize fugitive emissions.
    (5) When testing a new uncontrolled furnace the owner or operator
must either:
    (i) Install hooding that meets ACGIH Guidelines, or
    (ii) Petition the permitting authority that such hoods are
impracticable and propose testing procedures that will minimize
fugitive emissions.
* * * * *
    (h) * * *
    (1) The owner or operator of an in-line fluxer that uses reactive
flux materials must conduct a performance test to measure emissions of
HCl and PM or otherwise demonstrate compliance in accordance with
paragraph (h)(2) of this section. If the in-line fluxer is equipped
with an add-on control device, the emissions must be measured at the
outlet of the control device.
    (2) The owner or operator may choose to limit the rate at which
reactive flux is added to an in-line fluxer and assume, for the
purposes of demonstrating compliance with the SAPU emission limit, that
all chlorine in the reactive flux added to the in-line fluxer is
emitted as HCl. Under these circumstances, the owner or operator is not
required to conduct an emission test for HCl. If the owner or operator
of any in-line flux box which has no ventilation ductwork manifolded to
any outlet or emission control device chooses to demonstrate compliance
with the emission limits for HCl by limiting use of reactive flux and
assuming that all chlorine in the flux is emitted as HCl, compliance
with the HCl limit shall also constitute compliance with the emission
limit for PM, and no separate emission test for PM is required. In this
case, the owner or operator of the unvented in-line flux box must
utilize the maximum permissible PM emission rate for the in-line flux
boxes when determining the total emissions for any SAPU which includes
the flux box.
* * * * *
    (j) Secondary aluminum processing unit. The owner or operator must
conduct performance tests as described in paragraphs (j)(1) through (3)
of this section. The results of the performance tests are used to
establish emission rates in lb/ton of feed/charge for PM, HCl and HF
and [micro]g TEQ/Mg of feed/charge for D/F emissions from each emission
unit.

These emission rates are used for compliance monitoring in the
calculation of the 3-day, 24-hour rolling average emission rates using
the equation in Sec.  63.1510(t). A performance test is required for:
    (1) * * *
    (i) Emissions of HCl or HF (for the emission limits); or
* * * * *
    (2) * * *
    (i) Emissions of HCl or HF (for the emission limits); or
* * * * *
    (o) * * *
    (1) Continuously measure and record the weight of gaseous or liquid
reactive flux injected for each 15 minute period during the HCl, HF and
D/F tests, determine and record the 15-minute block average weights,
and calculate and record the total weight of the gaseous or liquid
reactive flux for the 3 test runs;
* * * * *
    (p) * * *
    (2) Record the feeder setting and lime injection rate for the 3
test runs. If the feed rate setting and lime injection rates vary
during the runs, determine and record the average feed rate and lime
injection rate from the 3 runs.
* * * * *
    10. Section 63.1513 is amended by:
    a. Revising paragraph (b) introductory text;
    b. Revising paragraph (b)(1);
    c. Revising paragraph (e)(1);
    d. Revising paragraph (e)(2); and
    e. Revising paragraph (e)(3)to read as follows:

Sec.  63.1513  Performance test/compliance demonstration requirements
and procedures.

* * * * *
    (b) PM, HCl, HF and D/F emission limits. (1) Use Equation 7 of this
section to determine compliance with an emission limit for PM, HCl or

[GRAPHIC] [TIFF OMITTED] TP14FE12.038

Where:

E = Emission rate of PM, HCl or HF, kg/Mg (lb/ton) of feed;
C = Concentration of PM, HCl or HF, g/dscm (gr/dscf);
Q = Volumetric flow rate of exhaust gases, dscm/hr (dscf/hr);
K1 = Conversion factor, 1 kg/1,000 g (1 lb/7,000 gr); and
P = Production rate, Mg/hr (ton/hr).
* * * * *
    (e) * * *
    (1) 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 Sec.  63.1505(k).
[GRAPHIC] [TIFF OMITTED] TP14FE12.039

Where,

EcPM = The mass-weighted PM emissions for the secondary
aluminum processing unit;
EtiPM = Measured PM emissions for individual emission
unit, or group of co-controlled emission units, i;
Tti = The average feed rate for individual emission unit
i during the operating cycle or performance test period, or the sum
of the average feed rates for all emission units in the group of co-
controlled emission unit i; and
n = The number of individual emission units, and groups of co-
controlled emission units in the secondary aluminum processing unit.
    (2) Use Equation 10 to compute the aluminum mass-weighted HCl or HF
emissions for the secondary aluminum processing unit. Compliance is
achieved if the mass-weighted emissions for the secondary aluminum
processing unit (EcHCl/HF) is less than or equal to the
emission limit for the secondary aluminum processing unit
(LcHCl/HF) calculated using Equation 2 in Sec.  63.1505(k).
[GRAPHIC] [TIFF OMITTED] TP14FE12.040

Where,

EcHCl/HF = The mass-weighted HCl or HF emissions for the
secondary aluminum processing unit; and
EtiHCl/HF = Measured HCl or HF emissions for individual
emission unit, or group of co-controlled emission units i.
    (3) 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 Sec.  63.1505(k).

[GRAPHIC] [TIFF OMITTED] TP14FE12.041

Where,

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, or group of co-controlled emission units i.

    15. Section 63.1520 is revised to read as follows:

Sec.  63.1520  Affirmative defense for violation of emission limit
during malfunction.

    In response to an action to enforce the standards set forth in this
subpart, you may assert an affirmative defense to a claim for civil
penalties for violations of such standards that are caused by
malfunction, as defined at Sec.  63.2. Appropriate penalties may be
assessed, however, if you fail to meet your burden of proving all of
the requirements in the affirmative defense. The affirmative defense
shall not be available for claims for injunctive relief.

    (a) To establish the affirmative defense in any action to enforce
such a limit, you must timely meet the notification requirements in
paragraph (b) of this section, and must prove by a preponderance of
evidence that:
    (1) The excess emissions:
    (i) Were caused by a sudden, infrequent and unavoidable failure of
air pollution control and monitoring equipment, process equipment, or a
process to operate in a normal or usual manner; and
    (ii) Could not have been prevented through careful planning, proper
design or better operation and maintenance practices; and
    (iii) Did not stem from any activity or event that could have been
foreseen and avoided, or planned for.
    (iv) Were not part of a recurring pattern indicative of inadequate
design, operation, or maintenance; and
    (2) Repairs were made as expeditiously as possible when the
applicable emission limitations were being exceeded. Off-shift and
overtime labor were used, to the extent practicable to make these
repairs; and
    (3) The frequency, amount and duration of the excess emissions
(including any bypass) were minimized to the maximum extent practicable
during periods of such emissions; and
    (4) If the excess emissions resulted from a bypass of control
equipment or a process, then the bypass was unavoidable to prevent loss
of life, personal injury, or severe property damage; and
    (5) All possible steps were taken to minimize the impact of the
excess emissions on ambient air quality, the environment and human
health; and
    (6) All emissions monitoring and control systems were kept in
operation if at all possible, consistent with safety and good air
pollution control practices; and
    (7) All of the actions in response to the excess emissions were
documented by properly signed, contemporaneous operating logs; and
    (8) At all times, the affected source was operated in a manner
consistent with good practices for minimizing emissions; and
    (9) A written root cause analysis has been prepared, the purpose of
which is to determine, correct, and eliminate the primary causes of the
malfunction and the excess emissions resulting from the malfunction
event at issue. The analysis shall also specify, using best monitoring
methods and engineering judgment, the amount of excess emissions that
were the result of the malfunction.
    (b) Reports. The owner or operator seeking to assert an affirmative
defense shall submit a written report to the Administrator within 45
days of the initial occurrence of the violation of the standards in
this subpart, which may be the end of any applicable averaging period,
to demonstrate, with all necessary supporting documentation, that it
has met the requirements set forth in paragraph (a) of this section.
The owner or operator may seek an extension of this deadline for up to
30 additional days by submitting a written request to the Administrator
before the expiration of the 45 day period. Until a request for an
extension has been approved by the Administrator, the owner or operator
is subject to the requirement to submit such report within 45 days of
the initial occurrence of the violation.
