(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 conduct performance tests while the product with the highest loss on ignition (LOI) expected to be produced by the affected facility is being manufactured.
(c) The owner or operator shall determine compliance with the particulate matter standard in § 60.682 as follows:
(1) The emission rate (E) of particulate matter shall be computed for each run using the following equation:
E=(Ct Qsd)/(Pavg K)
E = emission rate of particulate matter, kg/Mg (lb/ton).
Ct = concentration of particulate matter, g/dscm (gr/dscf).
Qsd = volumetric flow rate of effluent gas, dscm/hr (dscf/hr).
Pavg = average glass pull rate, Mg/hr (ton/hr).
K = 1,000 g/kg (7,000 gr/lb).
(2) Method 5E shall be used to determine the particulate matter concentration (Ct) and the volumetric flow rate (Qsd) of the effluent gas. The sampling time and sample volume shall be at least 120 minutes and 2.55 dscm (90.1 dscf).
(3) The average glass pull rate (Pavg) for the manufacturing line shall be the arithmetic average of three glass pull rate (Pi) determinations taken at intervals of at least 30 minutes during each run.
The individual glass pull rates (Pi) shall be computed using the following equation:
Pi=K′ Ls Wm M [1.0−(LOI/100)]
Pi=glass pull rate at interval “i”, Mg/hr (ton/hr).
