(a) In conducting the performance tests required in §60.8, the owner or operator shall use as reference methods and procedures the test methods in appendix A of this part or other methods and procedures as specified in this section, except as provided in § 60.8(b).

(b) The owner or operator shall determine compliance with the particulate matter standard in §60.52 as follows:

(1) The emission rate (C12) of particulate matter, corrected to 12 percent CO2, shall be computed for each run using the following equation:

C12 C, (12/%CO2) where:

C12=concentration of particulate matter, corrected to 12 percent CO2, g/dscm (gr/dscf). c,=concentration of particulate matter, g/ dscm (gr/dscf).

%CO2-CO2 concentration, percent dry basis.

(2) Method 5 shall be used to determine the particulate matter concentration (c,). The sampling time and sample volume for each run shall be at least 60 minutes and 0.85 dscm (30 dscf).

(3) The emission rate correction factor, integrated or grab sampling and

analysis procedure of Method 3B shall be used to determine CO2 concentration (%CO2).

(1) The CO2 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 CO2 traverse points may be reduced to 12 if Method 1 is used to locate the 12 CO2 traverse points. If individual CO2 samples are taken at each traverse point, the CO2 concentration (%CO2) used in the correction equation shall be the arithmetic mean of all the individual CO2 sample concentrations at each traverse point.

(ii) If sampling is conducted after a wet scrubber, an "adjusted" CO2 concentration [(%CO2)adj], which accounts for the effects of CO2 absorption and dilution air, may be used instead of the CO2 concentration determined in this paragraph. The adjusted CO2 centration shall be determined by either of the procedures in paragraph (c) of this section.

con

(c) The owner or operator may use elther of the following procedures to determine the adjusted CO2 concentration.

(1) The volumetric flow rates at the inlet and outlet of the wet scrubber and the inlet CO2 concentration may be used to determine the adjusted CO2 concentration [(%CO2)adj] using the following equation:

(%CO2)adj=(%CO2)di (Qdi/Qdo)

where:

(%CO2)adj-adjusted outlet CO2 concentration, percent dry basis.

(%CO2)di=CO2 concentration measured before the scrubber, percent dry basis. Qd=volumetric flow rate of effluent gas before the wet scrubber, dscm/min (dscf/ min). Qdo-volumetric flow rate of effluent gas after

the wet scrubber, dscm/min (dscf/min).

(1) At the outlet, Method 5 is used to determine the volumetric flow rate (Qdo) of the effluent gas.

(ii) At the inlet, Method 2 is used to determine the volumetric flow rate (Qi) 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.

(iii) At the inlet, the emission ra correction factor, integrated samplin and analysis procedure of Method 3B used to determine the CO2 concentr tion [(%CO2)di] as follows: At least ni sampling points are selected random from the velocity traverse points an are divided randomly into three set equal in number of points; the first se of three or more points is used for th first run, the second set for the secon run, and the third set for the third ru The CO2 sample is taken simulta neously with each particulate ru being conducted at the outlet, by tra versing the three sampling points (0) more) and sampling at each point fo equal increments of time.

(2) Excess air measurements may be used to determine the adjusted Co concentration [(%CO2)adj] using the fol lowing equation:

(%CO2) adj=(%CO2)di [(100+%EA;)/(100+%EA,)] where:

(%CO2)ad-adjusted outlet CO2 concentration percent dry basis.

(%CO2)di=CO2 concentration at the inlet o the wet scrubber, percent dry basis. %EA;-excess air at the inlet of the scrubber, percent.

%EA.-excess air at the outlet of the scrubber, percent.

(1) A gas sample is collected as in paragraph (c)(1)(iii) of this section and the gas samples at both the inlet and outlet locations are analyzed for CO2, O2, and N2.

(ii) Equation 3B-3 of Method 3B is used to compute the percentages of excess air at the inlet and outlet of the wet scrubber.
