NR 440.52(3)(b)(b) When 2 or more facilities at the same plant (except the lead oxide manufacturing facility) are ducted to a common control device, an equivalent standard for the total exhaust from the commonly controlled facilities shall be determined as follows: where:
Se is the equivalent standard for the total exhaust stream
Sa is the actual standard for each exhaust stream ducted to the control device
N is the total number of exhaust streams ducted to the control device
is the dry standard volumetric flow rate of the effluent gas stream from each facility ducted to the control device is the total dry standard volumetric flow rate of all effluent gas streams ducted to the control device NR 440.52(4)(4) Monitoring of emissions and operations. The owner or operator of any lead-acid battery manufacturing facility subject to the provisions of this section and controlled by scrubbing systems shall install, calibrate, maintain and operate a monitoring device or devices that measure and record the pressure drop across the scrubbing systems at least once every 15 minutes. The monitoring device shall have an accuracy of ± 5% over its operating range. NR 440.52(5)(a)(a) In conducting the performance tests required in s. NR 440.08, the owner or operator shall use as reference methods and procedures the test methods in Appendix A of 40 CFR part 60, incorporated by reference in s. NR 440.17, or other methods and procedures as specified in this subsection, except as provided in s. NR 440.08 (2). NR 440.52(5)(b)(b) The owner or operator shall determine compliance with the lead standards in sub. (3), except sub. (3) (a) 4., as follows: NR 440.52(5)(b)1.1. Method 12 shall be used to determine the lead concentration and, if applicable, the volumetric flow rate (Qsda) 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). NR 440.52(5)(b)2.2. When different operations in a 3-process operation facility are ducted to separate control devices, the lead emission concentration (C) from the facility shall be determined as follows: where:
C is the concentration of lead emissions for the entire facility, mg/dscm (gr/dscf)
Ca is the concentration of lead emissions from facility “a”, mg/dscm (gr/dscf)
Qsda is the volumetric flow rate of effluent gas from facility “a”, dscm/hr (dscf/hr)
N is the total number of control devices to which separate operations in the facility are ducted
NR 440.52(5)(b)3.3. Method 9 and the procedures in s. NR 440.11 shall be used to determine opacity. The opacity numbers shall be rounded off to the nearest whole percentage. NR 440.52(5)(c)1.1. The emission rate (E) from a lead oxide manufacturing facility shall be computed for each run using the following equation: where:
E is the emission rate of lead, mg/kg (lb/ton) of lead charged
CPbi is the concentration of lead from emission point “i”, mg/dscm (gr/dscf)
Qsdi is the volumetric flow rate of effluent gas from emission point “i”, dscm/hr (dscf/hr)
M is the number of emission points in the affected facility
P is the lead feed rate to the facility, kg/hr (ton/hr)
K is the conversion factor, 1.0 mg/mg (7000 gr/lb)
NR 440.52(5)(c)2.2. Method 12 shall be used to determine the lead concentration (CPb) and the volumetric flow rate 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).
