(8) PROCEDURES FOR CONDUCTING COMPLIANCE
EMISSION TESTS. In conducting any compliance emission test the following
procedures apply:
(a)
General
provisions. Except as provided for in par. (c), (d), (f) or (g), an
emission test shall consist of a minimum of 3 representative repetitions, as
determined by the department, of the applicable test method with a minimum
sampling time of one hour per repetition. Shorter sampling times as referenced
in par. (g) may be used with the written approval of the department. The
arithmetic mean of the results of all repetitions shall be used to determine
compliance with an emission limitation. In addition, the following requirements
apply:
1. The gas flow rate, in dry standard
cubic feet per minute, shall be determined during each repetition of an
emission test using Method 1, 1A, 2, 2A, 2B, 2C, 2D, 2E, 2F, 2G, 2H, 3, 3A, 3B,
and 4 in 40 CFR part 60, Appendix A, incorporated by reference in s.
NR 484.04(13), as applicable.
2. A record shall be maintained of all
persons who have handled the test samples.
(b)
Particulate matter. When
compliance with a particulate emission limitation is determined using Method 5,
5A, 5B, 5D, 5E, 5F, 5G, 5H, 5I, or 17 in 40 CFR part 60, Appendix A,
incorporated by reference in s.
NR 484.04(13), the test shall consist of
3 representative repetitions. In addition, the following provisions apply:
1. Sootblowing shall be performed during one
repetition of each test for particulate emissions on any boiler that routinely
employs sootblowing, unless the boiler uses a continuous sootblowing system. If
a continuous sootblowing system is operating during the test, compliance with
the emission limitation shall be determined by the arithmetic mean of the
results of all repetitions. If a continuous sootblowing system is not operating
during the test, the representative average pounds of particulate emissions per
million Btu heat input shall be determined by the following equation:
E = Es ((A + B) S/AR) +
Ens((R - S)/R - (BS/AR))
where:
E is the weighted average pounds of particulate matter per
million Btu heat input
Es is the pounds of particulate
matter per million Btu heat input for test runs during sootblowing
Ens is the arithmetic average pounds
of particulate matter per million Btu heat input for test runs with no
sootblowing
A is the hours of sootblowing during test runs containing
sootblowing
B is the hours with no sootblowing during test runs
containing sootblowing
R is the average hours of boiler operation per 24 hours
S is the average hours of sootblowing per 24 hours
2. Each repetition for a
particulate emission test shall have a sample volume of at least 30 dry
standard cubic feet.
3. Method 17,
for particulates, in 40 CFR part 60, Appendix A, incorporated by reference in
s.
NR 484.04(13), may not be used where
stack or duct temperatures exceed 320°F.
4. Heat input shall be equal to the fuel use
rate multiplied by the heat content of the fuel on an as-fired basis. Fuels
shall be analyzed for heat content using the procedures in Method 19 in 40 CFR
part 60, Appendix A, incorporated by reference in s.
NR 484.04(13).
5. Any boiler emission rate in pounds per
million Btu heat input shall be determined using the heat input based on fuel
use rate. The emission rate may be determined using the F-Factor calculation
shown in Method 19 in 40 CFR part 60, Appendix A, incorporated by reference in
s.
NR 484.04(13), with written approval
from the department. If the F-Factor method is used, an ultimate fuel analysis
shall be performed. An integrated gas sample, using Method 3, 3A or 3B in 40
CFR part 60, Appendix A, incorporated by reference in s.
NR 484.04(13), shall be collected and
analyzed for oxygen and carbon dioxide content. Other methods for determining
the boiler heat input may be used only if approved, in writing, by the
department.
6. If cyclonic flow is
a possibility at a particulate emission test location, a test for the presence
of cyclonic flow shall be performed before the particulate test using the
procedures in Method 1 in 40 CFR part 60, Appendix A, incorporated by reference
in s.
NR 484.04(13). If cyclonic flow is
present, the flow must be straightened before testing can begin unless the
source owner or operator demonstrates, to the department's satisfaction, the
acceptability of the location using the alternate procedure to Method 1. If
cyclonic flow is not present, testing can proceed.
7. Except for sources subject to emission
testing requirements in ch. NR 440, the department may require the owner or
operator of a source capable of emitting condensible particulate matter, to
include an analysis of the back half of the stack sampling train catch in the
total particulate catch for any emission test using Method 5, 5A, 5B, 5D, 5E,
5F, 5G, 5H, 5I, or 17, in 40 CFR part 60, Appendix A, incorporated by reference
in s.
NR 484.04(13). This procedure and
analysis shall be performed using Method 202 in 40 CFR part 51, Appendix M,
incorporated by reference in s.
NR 484.04(9).

3 repetitions. A repetition shall consist of 2 20-minute sampling periods with
each sampling period followed by a 15-minute fresh air purge. The 2 samples
shall be analyzed independently. The arithmetic mean of the results of the 2
samples shall be the result of that repetition.
2. When compliance with a sulfur dioxide
emission limitation is determined using Method 6B in 40 CFR part 60, Appendix
A, incorporated by reference in s.
