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 in § 60.8(b). (b) The owner or operator shall determine compliance with the particulate matter standards in § 60.342(a) 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 )/PK) where: E = emission rate of particulate matter, kg/Mg (1b/ton) of stone feed. c s = concentration of particulate matter, g/dscm (gr/dscf). Q sd = volumetric flow rate of effluent gas, dscm/hr (dscf/hr). P = stone feed rate, Mg/hr (ton/hr). K = conversion factor, 1000 g/kg (7000 gr/lb). (2) Method 5 shall be used at negative-pressure fabric filters and other types of control devices and Method 5D shall be used at positive-pressure fabric filters to determine the particulate matter concentration (c s ) and the 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 0.90 dscm (31.8 dscf). (3) The monitoring device of § 60.343(d) shall be used to determine the stone feed rate (P) for each run. (4) Method 9 and the procedures in § 60.11 shall be used to determine opacity. (c) During the particulate matter run, the owner or operator shall use the monitoring devices in § 60.343(c)(1) and (2) to determine the average pressure loss of the gas stream through the scrubber and the average scrubbing liquid supply pressure.
