NR 440.207(7)(d)1.
1. For affected facilities combusting coal or oil, coal or oil samples shall be collected daily in an as-fired condition at the inlet to the steam generating unit and analyzed for sulfur content and heat content according to Method 19. Method 19 provides procedures for converting these measurements into the format to be used in calculating the average SO
2 input rate.
NR 440.207(7)(d)2.
2. As an alternative fuel sampling procedure for affected facilities combusting oil, oil samples may be collected from the fuel tank for each steam generating unit immediately after the fuel tank is filled and before any oil is combusted. The owner or operator of an affected facility shall analyze the oil sample to determine the sulfur content of the oil. If a partially empty fuel tank is refilled, a new sample and analysis of the fuel in the tank is required upon filling. Results of the fuel analysis taken after each new shipment of oil is received shall be used as the daily value when calculating the 30-day rolling average until the next shipment is received. If the fuel analysis shows that the sulfur content in the fuel tank is greater than 0.5 weight percent sulfur, the owner or operator shall ensure that the sulfur content of subsequent oil shipments is low enough to cause the 30-day rolling average sulfur content to be 0.5 weight percent sulfur or less.
NR 440.207(7)(d)3.
3. Method 6B may be used in lieu of CEMS to measure SO
2 at the inlet or outlet of the SO
2 control system. An initial stratification test is required to verify the adequacy of the Method 6B sampling location. The stratification test shall consist of 3 paired runs of a suitable SO
2 and carbon dioxide measurement train operated at the candidate location and a second similar train operated according to the procedures in
s. 3.2 and the applicable procedures in section 7 of Performance Specification 2 of
40 CFR part 60 Appendix B, incorporated by reference in
s. NR 440.17. Method 6B, Method 6A or a combination of Methods 6 and 3 or Methods 6C and 3A are suitable measurement techniques. If Method 6B is used for the second train, sampling time and timer operation may be adjusted for the stratification test as long as an adequate sample volume is collected; however, both sampling trains are to be operated similarly. For the location to be adequate for Method 6B 24-hour tests, then the mean of the absolute difference between the 3 paired runs shall be less than 10% (0.10).

s. NR 440.08, whichever date comes first, no owner or operator subject to the provisions of this section may cause to be discharged into the atmosphere from any affected facility any gases which contain particulate matter in excess of 0.18 g/dscm (0.08 gr/dscf) corrected to 12% CO
2.
NR 440.21(4)
(4) Monitoring of operations. The owner or operator of any incinerator subject to the provisions of this section shall record the daily charging rates and hours of operation.
NR 440.21(5)(a)(a) In conducting the performance tests required in
s. NR 440.08, the owner or operator shall use as reference methods and procedures the test methods in Appendix A of
40 CFR part 60, incorporated by reference in
s. NR 440.17, or other methods and procedures as specified in this subsection, except as provided in
s. NR 440.08 (2).
NR 440.21(5)(b)
(b) The owner or operator shall determine compliance with the particulate matter standard in
sub. (3) as follows:
NR 440.21(5)(b)1.
1. The concentration (C
12) of particulate matter, corrected to 12% CO
2, shall be computed for each run using the following equation:
C12 = Cs (12/%CO2)
where:
C12 is the concentration of particulate matter corrected to 12% CO2 g/dscm (gr/dscf)
Cs is the concentration of particulate matter, g/dscm (gr/dscf)
%CO2 is the CO2 concentration, percent dry basis
NR 440.21(5)(b)2.
2. Method 5 shall be used to determine the particulate matter concentration (C
s). The sampling time and sample volume for each run shall be at least 60 minutes and 0.85 dscm (30 dscf).
NR 440.21(5)(b)3.
3. The emission rate correction factor, integrated or grab sampling and analysis procedure of Method 3B shall be used to determine CO
2 concentration (%CO
2).
NR 440.21(5)(b)3.a.
a. The CO
2 sample shall be obtained simultaneously with, and at the same traverse points as, the particulate run. If the particulate run has more than 12 traverse points, the CO
2 traverse points may be reduced to 12 if Method 1 is used to locate the 12 CO
2 traverse points. If individual CO
2 samples are taken at each traverse point, the CO
2 concentration (%CO
2) used in the correction equation shall be the arithmetic mean of the sample CO
2 concentrations at all traverse points.
NR 440.21(5)(b)3.b.
b. If sampling is conducted after a wet scrubber, an “adjusted" CO
2 concentration, (%CO
2)
adj, which accounts for the effects of CO
2 absorption and dilution air, may be used instead of the CO
2 concentration determined in this paragraph. The adjusted CO
2 concentration shall be determined by either of the procedures in
par. (c).
NR 440.21(5)(c)
(c) The owner or operator may use either of the following procedures to determine the adjusted CO
2 concentration.
NR 440.21(5)(c)1.
1. The volumetric flow rates at the inlet and outlet of the wet scrubber and the inlet CO
2 concentration may be used to determine the adjusted concentration, (%CO
2)
adj, using the following equation:
(%CO2)adj, = (%CO2)di (Qdi/Qdo)
where:
(%CO2)adj is the adjusted outlet CO2 concentration, percent dry basis
(%CO2)di is the CO2 concentration measured before the scrubber, percent dry basis
Qdi is the volumetric flow rate of effluent gas before the wet scrubber, dscm/min (dscf/min)
Qdo is the volumetric flow rate of effluent gas after the wet scrubber, dscm/min (dscf/min)
NR 440.21(5)(c)1.a.
a. At the outlet, Method 5 is used to determine the volumetric flow rate (Q
do) of the effluent gas.
NR 440.21(5)(c)1.b.
b. At the inlet, Method 2 is used to determine the volumetric flow rate (Q
di) of the effluent gas as follows: Two full velocity traverses are conducted, one immediately before and one immediately after each particulate run conducted at the outlet, and the results are averaged.
NR 440.21(5)(c)1.c.
c. At the inlet, the emission rate correction factor, integrated sampling and analysis procedure of Method 3B is used to determine the CO
2 concentration, (%CO
2)
di, as follows: At least 9 sampling points are selected randomly from the velocity traverse points and are divided randomly into 3 sets, equal in number of points; the first set of 3 or more points is used for the first run, the second set for the second run, and the third set for the third run. The CO
2 sample is taken simultaneously with each particulate run being conducted at the outlet, by traversing the 3 sampling points, or more, and sampling at each point for equal increments of time.
NR 440.21(5)(c)2.
2. Excess air measurements may be used to determine the adjusted CO
2 concentration, (%CO
2)
adj, using the following equation:
(%CO2)adj = (%CO2)di [(100 + %EAi)/ (100 + %EAo)]
where:
(%CO2)adj is the adjusted outlet CO2 concentration, percent dry basis
(%CO2)di is the CO2 concentration at the inlet of the wet scrubber, percent dry basis
%EAi is the excess air at the inlet of the scrubber, percent
%EAo is the excess air at the outlet of the scrubber, percent
