Current through August 26, 2024
(1)
(a) Except as provided in par. (c), the owner
or operator of an affected source shall use Method 311 in 40 CFR part 63, Appendix A, incorporated by reference in s.
NR 484.04(25), in conjunction with
formulation data, to determine the VHAP content of liquid coatings. Formulation
data shall be used to identify VHAP present in the coating. Method 311 shall
then be used to quantify those VHAP identified through formulation data. Method
311 may not be used to quantify HAP such as styrene and formaldehyde that are
emitted during the cure.
(b) Except
as provided in par. (c), the owner or operator of an affected source shall use
Method 24 in 40 CFR part 60, Appendix A, incorporated by reference in s.
NR 484.04(13), to determine the solids
content by weight and the density of coatings.
(c) If it is demonstrated to the satisfaction
of the administrator that a coating does not release VOC or HAP byproducts
during the cure, batch formulation information shall be accepted for
determining the VHAP or VOC content of the coating. The owner or operator of an
affected source may request approval from the administrator to use an
alternative method for determining the VHAP content of the coating. In the
event of any inconsistency between Method 24 or Method 311 test data for a
material and formulation data for the same material, the applicable test method
shall govern unless, after consultation, the owner or operator can demonstrate
to the satisfaction of the department that the formulation data are
correct.
(2) An owner or
operator demonstrating compliance in accordance with s.
NR 465.07(1) (d)
or (2) (b) or 465.08(1) (d) or (2)
(b), or complying with any of the other
emission limits of s.
NR 465.04 by operating a capture and control device,
shall determine the overall control efficiency of the control system (R) as the
product of the capture and control device efficiency, using the test methods in
sub. (3) and the procedures in sub. (4).
(3) When an initial compliance demonstration
is required by s.
NR 465.07(1) (d)
or (2) (b), the following test methods shall
be used:
(a) Method 18 in 40 CFR part 60,
Appendix A, incorporated by reference in s.
NR 484.04(13), shall be used to
determine the HAP concentration of gaseous air streams. The test shall consist
of 3 separate runs, each lasting a minimum of 30 minutes.
(b) Method 1 or 1A in 40 CFR part 60,
Appendix A, incorporated by reference in s.
NR 484.04(13), shall be used for sample
and velocity traverses.
(c) Method
2, 2A, 2C or 2D in 40 CFR part 60, Appendix A, incorporated by reference in s.
NR 484.04(13), shall be used to measure
velocity and volumetric flow rates.
(d) Method 3 in 40 CFR part 60, Appendix A,
incorporated by reference in s.
NR 484.04(13), shall be used to analyze
the exhaust gases.
(e) Method 4 in
40 CFR part 60, Appendix A, incorporated by reference in s.
NR 484.04(13), shall be used to measure
the moisture in the stack gas.
(f)
Methods 2, 2A, 2C, 2D, 3 and 4 in 40 CFR part 60, Appendix A, incorporated by
reference in s.
NR 484.04(13), shall be performed, as
applicable, at least twice during each test period.
(4) An owner or operator of an affected
source demonstrating compliance in accordance with s.
NR 465.07(1) (d)
or (2) (b) shall perform a gaseous emission
test using the following procedures:
(a)
Construct the overall HAP emission reduction system so that all volumetric flow
rates and total HAP emissions can be accurately determined by the applicable
test methods specified in sub. (3).
(b) Determine capture efficiency from the
affected emission points by capturing, venting and measuring all HAP emissions
from the affected emission points. The owner or operator shall isolate affected
emission points located in an area with other nonaffected gaseous emission
sources from all other gaseous emission points and shall determine capture
efficiency according to the following procedures as appropriate:
1. For temporary total enclosures, capture
efficiency shall be determined according to Method 204, and as applicable,
Methods 204A through 204F, in 40 CFR part 51, Appendix M, incorporated by
reference in s.
NR 484.04(9).
2. For permanent total enclosures built
around the affected emissions points, and where the building that houses the
process is used as the enclosure, capture efficiency shall be assumed to be
100% when the requirements for a permanent total enclosure in Method 204, in 40
CFR part 51, Appendix M, incorporated by reference in s.
NR 484.04(9), are satisfied.
Notwithstanding par. (e), when a permanent total enclosure is confirmed through
Method 204, a value of one shall be used for N when determining R under sub.
(5), (6), (7) or (8).
3. Use any
alternative protocol and test method provided they meet either the requirements
of the data quality objective (DQO) approach or the lower confidence level
(LCL) approach in 40 CFR part 63, Subpart KK, Appendix A, incorporated by
reference in s.
NR 484.04(24).
4. Shut down all nonaffected HAP emission
points and continue to exhaust fugitive emissions from the affected emission
points through any building ventilation system and other room exhausts such as
drying ovens. All exhaust air shall be vented through stacks suitable for
testing.
5. Use another methodology
approved by the administrator provided it complies with the criteria for
acceptance under Method 301 in 40 CFR part 63, Appendix A, incorporated by
reference in s.
NR 484.04(25).
(c) Operate the control device with all
affected emission points that will subsequently be delivered to the control
device connected and operating at maximum production rate.
(d) Determine the efficiency (F) of the
control device using the following equation:

(e)
Determine the efficiency (N) of the capture system using the following
equation:
