Current through August 26, 2024
(1)
SITE-SPECIFIC TEST PLAN. Prior to conducting any performance test required by
this subchapter, the owner or operator shall prepare a site-specific test plan
which satisfies all of the requirements of this section, and shall obtain
review and evaluation of the plan by the department pursuant to the procedures
in s.
NR 460.06.
(2) INITIAL PERFORMANCE TEST.
(a) Following the review and evaluation of
the site-specific test plan, the owner or operator shall 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 s.
NR 463.17(2). The owner or operator of
any existing affected source for which an initial performance test is required
to demonstrate compliance shall conduct this initial performance test no later
than the date for compliance established by s.
NR 463.115(1). The owner or operator of
any new affected source for which an initial performance test is required shall
conduct this initial performance test within 90 days after the date for
compliance established by s.
NR 463.115(2). Except for the date by
which the performance test shall be conducted, the owner or operator shall
conduct each performance test in accordance with the requirements and
procedures in s.
NR 460.06(2). 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 s.
NR 463.13(6) are not required to conduct
a performance test.
(b) The owner
or operator shall conduct each test while the affected source or emission unit
is operating at the highest production level with charge materials
representative of the range of materials processed by the unit and, if
applicable, at the highest reactive fluxing rate.
(c) Each performance test for a continuous
process shall consist of 3 separate runs; pollutant sampling for each run shall
be conducted for the time period specified in the applicable method or, in the
absence of a specific time period in the test method, for a minimum of 3
hours.
(d) Each performance test
for a batch process shall consist of 3 separate runs; pollutant sampling for
each run shall be conducted over the entire process operating cycle.
(e) Where multiple affected sources or
emission units are exhausted through a common stack, pollutant sampling for
each run shall be conducted over a period of time during which all affected
sources or emission units complete at least one entire process operating cycle
or for 24 hours, whichever is shorter.
(f) Initial compliance with an applicable
emission limit or standard is demonstrated if the average of 3 runs conducted
during the performance test is less than or equal to the applicable emission
limit or standard.
(3)
TEST METHODS. The owner or operator shall use the following methods in Appendix
A to 40 CFR part 60, incorporated by reference in s.
NR 484.04(13), to determine compliance
with the applicable emission limits or standards:
(a) Method 1 for sample and velocity
traverses.
(b) Method 2 for
velocity and volumetric flow rate.
(c) Method 3 for gas analysis.
(d) Method 4 for moisture content of the
stack gas.
(e) Method 5 for the
concentration of PM.
(f) Method 9
for visible emission observations.
(g) Method 23 for the concentration of
D&F.
(h) Method 25A for the
concentration of THC, as propane.
(i) Method 26A for the concentration of HCl.
Where a lime-injected fabric filter is used as the control device to comply
with the 90% reduction standard, the owner or operator shall measure the fabric
filter inlet concentration of HCl at a point before lime is introduced to the
system.
(4) ALTERNATIVE
METHODS. The owner or operator may use an alternative test method, subject to
approval by the department.
(5)
REPEAT TESTS. The owner or operator of new or existing affected sources and
emission units located at secondary aluminum production facilities that are
major sources shall conduct a performance test every 5 years following the
initial performance test.
(6)
TESTING OF REPRESENTATIVE EMISSION UNITS. With the prior approval of the
department, an owner or operator may utilize emission rates obtained by testing
a particular type of group 1 furnace which is not controlled by any add-on
control device, or by testing an in-line flux box which is not controlled by
any add-on control device, to determine the emission rate for other units of
the same type at the same facility. Emission test results may only be
considered to be representative of other units if all of the following criteria
are satisfied:
(a) The tested emission unit
uses feed materials and charge rates which are comparable to the emission units
that it represents.
(b) The tested
emission unit uses the same type of flux materials in the same proportions as
the emission units it represents.
(c) The tested emission unit is operated
utilizing the same work practices as the emission units that it
represents.
(d) The tested emission
unit is of the same design as the emission units that it represents.
(e) The tested emission unit is tested under
the highest load or capacity reasonably expected to occur for any of the
emission units that it represents.
(7) ESTABLISHMENT OF MONITORING AND OPERATING
PARAMETER VALUES. The owner or operator of new or existing affected sources and
emission units shall establish a minimum or maximum operating parameter value,
or an operating parameter range, for each parameter to be monitored as required
by s.
NR 463.15
that ensures compliance with the applicable emission limit or standard. To
establish the minimum or maximum value or range, the owner or operator shall
use the appropriate procedures in this section and submit the information
required by s.
NR 463.17(2) (d) in the notification of
compliance status report. The owner or operator may use existing data in
addition to the results of performance tests to establish operating parameter
values for compliance monitoring provided each of the following conditions are
met to the satisfaction of the department:
(a) The complete emission test report used as
the basis of the parameter or parameters is submitted.
(b) The same test methods and procedures as
required by this subchapter were used in the test.
(c) The owner or operator certifies that no
design or work practice changes have been made to the source, process or
emission control equipment since the time of the report.
(d) All process and control equipment
operating parameters required to be monitored were monitored as required in
this subchapter and documented in the test report.
(8) TESTING OF COMMONLY-DUCTED UNITS WITHIN A
SECONDARY ALUMINUM PROCESSING UNIT. When group 1 furnaces and in-line fluxers
are included in a single existing SAPU or new SAPU, and the emissions from more
than one emission unit within that existing SAPU or new SAPU are manifolded to
a single control device, compliance for all units within the SAPU is
demonstrated if the total measured emissions from all controlled and
uncontrolled units in the SAPU do not exceed the emission limits calculated for
that SAPU based on the applicable equation in s.
NR 463.13(11).
(9) TESTING OF COMMONLY-DUCTED UNITS NOT
WITHIN A SECONDARY ALUMINUM PROCESSING UNIT. With the prior approval of the
department, an owner or operator may do combined performance testing of 2 or
more individual affected sources or emission units which are not included in a
single existing SAPU or new SAPU, but whose emissions are manifolded to a
single control device. Any performance testing of commonly-ducted units shall
satisfy all the following basic requirements:
(a) All testing shall be designed to verify
that each affected source or emission unit individually satisfies all emission
requirements applicable to that affected source or emission unit.
(b) All emissions of pollutants subject to a
standard shall be tested at the outlet from each individual affected source or
emission unit while operating under the highest load or capacity reasonably
expected to occur, and prior to the point that the emissions are manifolded
together with emissions from other affected sources or emission
units.
(c) The combined emissions
from all affected sources and emission units which are manifolded to a single
emission control device shall be tested at the outlet of the emission control
device.
(d) All tests at the outlet
of the emission control device shall be conducted with all affected sources and
emission units whose emissions are manifolded to the control device operating
simultaneously under the highest load or capacity reasonably expected to
occur.
(e) For purposes of
demonstrating compliance of a commonly-ducted unit with any emission limit for
a particular type of pollutant, the emissions of that pollutant by the
individual unit shall be presumed to be controlled by the same percentage as
total emissions of that pollutant from all commonly-ducted units are controlled
at the outlet of the emission control device.
