NR 463.09(5)(a)(a) This subsection identifies procedures for measuring the outlet chromium concentration from an add-on air pollution control device that is used to control multiple sources that may or may not include sources not affected by this subchapter. NR 463.09(5)(b)(b) When multiple affected sources performing the same type of operation (for example, all are performing hard chromium electroplating), and subject to the same emission limitation, are controlled with an add-on air pollution control device that is not controlling emissions from any other type of affected operation or from any sources not affected by this subchapter, the applicable emission limitation identified in s. NR 463.04 shall be met at the outlet of the add-on air pollution control device. NR 463.09(5)(c)(c) When multiple affected sources performing the same type of operation and subject to the same emission limitation are controlled with a common add-on air pollution control device that is also controlling emissions from sources not affected by this subchapter, the following procedures shall be followed to determine compliance with the applicable emission limitation in s. NR 463.04: NR 463.09(5)(c)1.1. Calculate the cross-sectional area of each inlet duct (uptakes from each hood) including those not affected by this subchapter. NR 463.09(5)(c)2.2. Determine the total sample time per test run by dividing the total inlet area from all tanks connected to the control system by the total inlet area for all ducts associated with affected sources, and then multiply this number by 2 hours. The calculated time is the minimum sample time required per test run. NR 463.09(5)(c)4.4. Determine the total ventilation rate from the affected sources by using equation 1: where VRtot is the average total ventilation rate in dscm/min for the 3 test runs as determined at the outlet by means of the Method 306 testing; IDAi is the total inlet area for all ducts associated with affected sources; IAtotal is the sum of all inlet duct areas from both affected sources and sources not affected by this subchapter; and VRinlet is the total ventilation rate from all inlet ducts associated with affected sources.
NR 463.09(5)(c)5.5. Establish the allowable mass emission rate of the system (AMRsys) in milligrams of total chromium per hour (mg/hr) using equation 2: where S VRinlet is the total ventilation rate in dscm/min from the affected sources, and EL is the applicable emission limitation from s. NR 463.04 in mg/dscm. The allowable mass emission rate (AMRsys) calculated from equation 2 shall be equal to or more than the outlet 3-run average mass emission rate determined from Method 306 testing in order for the source to be in compliance with the standard. NR 463.09(5)(d)(d) When multiple affected sources performing different types of operations (for example, hard chromium electroplating, decorative chromium electroplating or chromium anodizing) are controlled by a common add-on air pollution control device that may or may not also be controlling emissions from sources not affected by this subchapter, or if the affected sources controlled by the common add-on air pollution control device perform the same operation but are subject to different emission limitations (for example, because one is a new hard chromium plating tank and one is an existing small, hard chromium plating tank), the following procedures shall be followed to determine compliance with the applicable emission limitation in s. NR 463.04: NR 463.09(5)(d)2.2. Determine the total ventilation rate for each type of affected source using equation 3: where VRtot is the average total ventilation rate in dscm/min for the 3 test runs as determined at the outlet by means of the Method 306 testing; IDAi,a is the total inlet duct area for all ducts conveying chromic acid from each type of affected source performing the same operation, or each type of affected source subject to the same emission limitation; IAtotal is the sum of all duct areas from both affected sources and sources not affected by this subchapter; and VRinlet,a is the total ventilation rate from all inlet ducts conveying chromic acid from each type of affected source performing the same operation, or each type of affected source subject to the same emission limitation.
NR 463.09(5)(d)3.3. Establish the allowable mass emission rate in mg/hr for each type of affected source that is controlled by the add-on air pollution control device using equation 4, 5, 6 or 7 as appropriate: where “hc” applies to the total of ventilation rates for all hard chromium electroplating tanks subject to the same emission limitation, “dc” applies to the total of ventilation rates for the decorative chromium electroplating tanks, “ca” applies to the total of ventilation rates for the chromium anodizing tanks, and EL is the applicable emission limitation from s. NR 463.04 in mg/dscm. There are 2 equations for hard chromium electroplating tanks because different emission limitations may apply (for example, a new tank versus an existing, small tank). NR 463.09(5)(d)4.4. Establish the allowable mass emission rate (AMR) in mg/hr for the system using equation 8, including each type of affected source as appropriate: The allowable mass emission rate calculated from equation 8 shall be equal to or more than the outlet 3-run average mass emission rate determined from Method 306 testing in order for the source to be in compliance with the standards in s. NR 463.04. NR 463.09(5)(e)(e) Each owner or operator that uses the special compliance provisions of this subsection to demonstrate compliance with the emission limitations of s. NR 463.04 shall submit the measurements and calculations to support these compliance methods with the notification of compliance status required by s. NR 463.106 (5). NR 463.09(5)(f)(f) Each owner or operator that uses the special compliance provisions of this subsection to demonstrate compliance with the emission limitations of s. NR 463.04 shall repeat these procedures if a tank is added or removed from the control system regardless of whether that tank is not an affected source. If neither the new tank nor the existing tank is an affected source and the new tank replaces an existing tank of the same size and is connected to the control system through the same size inlet duct, then this procedure does not have to be repeated. NR 463.09(6)(6) Compliance provisions for mass rate emission standard for enclosed hard chromium electroplating tanks. NR 463.09(6)(a)(a) This subsection identifies procedures for calculating the maximum allowable mass emission rate for owners or operators of affected sources who choose to meet the mass emission rate standard in s.

NR 463.09(6)(b)(b) The owner or operator of an enclosed hard chromium electroplating tank that is an affected source other than an existing affected source located at a small hard chromium electroplating facility who chooses to meet the mass emission rate standard in s. NR 463.04 (3) (b) 4. shall determine compliance by not allowing the mass rate of total chromium in the exhaust gas stream discharged to the atmosphere to exceed the maximum allowable mass emission rate calculated using equation 9: MAMER = ETSA x K x 0.015 mg/dscm Equation (9)
where:
MAMER is the alternative emission rate for enclosed hard chromium electroplating tanks in mg/hr
ETSA is the hard chromium electroplating tank surface area in square feet (ft2)
K is the conversion factor, 425 dscm/(ft2 x hr)
NR 463.09(6)(c)(c) Compliance with the alternative mass emission limit in s. NR 463.04 (3) (b) 4. is demonstrated if the 3-run average mass emission rate determined from Method 306 in Appendix A of 40 CFR part 63, incorporated by reference in s. NR 484.04 (25), testing is less than or equal to the maximum allowable mass emission rate calculated from equation 9 in par. (b). NR 463.09(6)(d)(d) The owner or operator of an enclosed hard chromium electroplating tank that is an existing affected source located at a small hard chromium electroplating facility who chooses to meet the mass emission rate standard in s. NR 463.04 (3) (b) 5. shall determine compliance by not allowing the mass rate of total chromium in the exhaust gas stream discharged to the atmosphere to exceed the maximum allowable mass emission rate calculated using equation 10: MAMER = ETSA x K x 0.03 mg/dscm Equation (10)
where:
MAMER is the alternative emission rate for enclosed hard chromium electroplating tanks in mg/hr
ETSA is the hard chromium electroplating tank surface area in square feet (ft2)
K is the conversion factor, 425 dscm/(ft2 x hr)
NR 463.09(6)(e)(e) Compliance with the alternative mass emission limit in s.
