Sec. 60.54  Test methods and procedures.

    (a) In conducting the performance tests required in Sec. 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 Sec. 60.8(b).
    (b) The owner or operator shall determine compliance with the 
particulate matter standard in Sec. 60.52 as follows:
    (1) The concentration (c12) of particulate matter, 
corrected to 12 percent CO2, shall be computed for each run 
using the following equation:

c12 = cs (12/%CO2)

where:

c12=concentration of particulate matter, corrected to 12 
percent CO2, g/dscm (gr/dscf).
cs=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 (cs). 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).
    (i) 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 the sample CO2 concentrations at all 
traverse points.
    (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 concentration shall be 
determined by either of the procedures in paragraph (c) of this section.
    (c) The owner or operator may use either 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.
Qdi=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).

    (i) 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 (Qdi) 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 rate correction factor, integrated 
sampling and analysis procedure of Method 3B is used to determine the 
CO2 concentration [(%CO2)di] as 
follows: At least nine sampling points are selected randomly from the 
velocity traverse points and are divided randomly into three sets, equal 
in number of points; the first set of three 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 CO2 sample is taken simultaneously with 
each particulate run being conducted at the outlet, by traversing the 
three sampling points (or more) and sampling at each point for equal 
increments of time.
    (2) Excess air measurements may be used to determine the adjusted 
CO2 concentration [(%CO2)adj] using the 
following equation:

(%CO2)adj=(%CO2)di 
    [(100+%EAi)/(100+%EAo)]

where:

(%CO2)adj=adjusted outlet CO2 
concentration, percent dry basis.
(%CO2)di=CO2 concentration at the inlet 
of the wet scrubber, percent dry basis.

[[Page 237]]

%EAi=excess air at the inlet of the scrubber, percent.
%EAo=excess air at the outlet of the scrubber, percent.

    (i) 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.
