Sec. 60.85  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). 
Acceptable alternative methods and procedures are given in paragraph (c) 
of this section.
    (b) The owner or operator shall determine compliance with the 
SO2 acid mist, and visible emission standards in Sec. Sec. 
60.82 and 60.83 as follows:
    (1) The emission rate (E) of acid mist or SO2 shall be 
computed for each run using the following equation:

E=(CQsd)/(PK)

where:

E=emission rate of acid mist or SO2 kg/metric ton (lb/ton) of 
100 percent H2SO4 produced.
C=concentration of acid mist or SO2, g/dscm (lb/dscf).
Qsd=volumetric flow rate of the effluent gas, dscm/hr (dscf/
hr).
P=production rate of 100 percent H2SO4, metric 
ton/hr (ton/hr).
K=conversion factor, 1000 g/kg (1.0 lb/lb).

    (2) Method 8 shall be used to determine the acid mist and 
SO2 concentrations (C's) and the volumetric flow rate 
(Qsd) of the effluent gas. The moisture content may be 
considered to be zero. The sampling time and sample volume for each run 
shall be at least 60 minutes and 1.15 dscm (40.6 dscf).
    (3) Suitable methods shall be used to determine the production rate 
(P) of 100 percent H2SO4 for each run. Material 
balance over the production system shall be used to confirm the 
production rate.
    (4) Method 9 and the procedures in Sec. 60.11 shall be used to 
determine opacity.
    (c) The owner or operator may use the following as alternatives to 
the reference methods and procedures specified in this section:
    (1) If a source processes elemental sulfur or an ore that contains 
elemental sulfur and uses air to supply oxygen, the following procedure 
may be used instead of determining the volumetric flow rate and 
production rate:
    (i) The integrated technique of Method 3 is used to determine the 
O2 concentration and, if required, CO2 
concentration.
    (ii) The SO2 or acid mist emission rate is calculated as 
described in Sec. 60.84(d), substituting the acid mist concentration 
for Cs as appropriate.
