Sec. 60.404  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 for in Sec. 60.8(b).
    (b) The owner or operator shall determine compliance with the 
particulate matter standards in Sec. 60.402 as follows:
    (1) The emission rate (E) of particulate matter shall be computed 
for each run using the following equation:

E=(cs Qsd)/(P K)

where:

E=emission rate of particulate matter, kg/Mg (lb/ton) of phosphate rock 
feed.
cs=concentration of particulate matter, g/dscm (g/dscf).
Qsd=volumetric flow rate of effluent gas, dscm/hr (dscf/hr).
P=phosphate rock feed rate, Mg/hr (ton/hr).
K=conversion factor, 1000 g/kg (453.6 g/lb).

    (2) Method 5 shall be used to determine the particulate matter 
concentration (cs) and volumetric flow rate (Qsd) 
of the effluent gas. The sampling time and sample volume for each run 
shall be at least 60 minutes and 0.85 dscm (30 dscf).
    (3) The device of Sec. 60.403(d) shall be used to determine the 
phosphate rock feed rate (P) for each run.
    (4) Method 9 and the procedures in Sec. 60.11 shall be used to 
determine opacity.
    (c) To comply with Sec. 60.403(f), if applicable, the owner or 
operator shall use the monitoring devices in Sec. 60.403(c) (1) and (2) 
to determine the average pressure loss of the gas stream through the 
scrubber and the average scrubbing supply pressure during the 
particulate matter runs.
