This demonstration shall be made during the initial performance test, and a subsequent demonstration may be requested at any other time. If the demonstrated 24-hour average firing rate for the affected facility is less than the maximum design heat input capacity stated by the manufacturer of the affected facility, the demonstrated 24-hour average firing rate shall be used to the determine annual capacity factor for the affected facility; otherwise, the maximum design heat input capacity provided by the manufacturer shall be used.

sub. (3). Each 1-hour average SO
2 emission rate shall be based on at least 30 minutes of operation and include at least 2 data points representing 2 15-minute periods. Hourly SO
2 emission rates are not calculated if the affected facility is operated less than 30 minutes in a 1-hour period and are not counted toward determination of a steam generating unit operating day.

2 emission rate of the fuel combusted, and the span value of the SO
2 CEMS at the outlet from the SO
2 control device shall be 50% of the maximum estimated hourly potential SO
2 rate of the fuel combusted.
NR 440.207(7)(c)4.

2 control device is used, shall be 125% of the maximum estimated hourly potential SO
2 emission rate of the fuel combusted.

2 control device is used, as required under
par. (a), an owner or operator may elect to determine the average SO
2 emission rate by sampling the fuel prior to combustion. As an alternative to operating a CEMS at the outlet from the SO
2 control device, or outlet of the steam generating unit if no SO
2 control device is used, as required under
par. (a), an owner or operator may elect to determine the average SO

subd. 3.
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

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

(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
