§60.404 Test methods and procedures.

(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 for in �60.8(b).

(b) The owner or operator shall determine compliance with the particulate matter standards in �60.402 as follows:

(1) The emission rate (E) of particulate matter shall be computed for each run using the following equation:

E = (c_s Q_sd)/(P K)

where:

E = emission rate of particulate matter, kg/Mg (lb/ton) of phosphate rock feed.

c_s = concentration of particulate matter, g/dscm (g/dscf).

Q_sd = 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 (c_s) and volumetric flow rate (Q_sd) 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 �60.403(d) shall be used to determine the phosphate rock feed rate (P) for each run.

(4) Method 9 and the procedures in �60.11 shall be used to determine opacity.

(c) To comply with �60.403(f), if applicable, the owner or operator shall use the monitoring devices in �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.
