NR 463.14(3)(a)(a) Design and install a system for the capture and collection of emissions to meet the engineering standards for minimum exhaust rates as published by the American Conference of Governmental Industrial Hygienists in chapters 3 and 5 of Industrial Ventilation: A Manual of Recommended Practice, incorporated by reference in s. NR 484.11 (2) (d).

NR 463.14(3)(b)(b) Vent captured emissions through a closed system, except that dilution air may be added to emission streams for the purpose of controlling temperature at the inlet to a fabric filter.

NR 463.14(3)(c)(c) Operate each capture and collection system according to the procedures and requirements in the operation, maintenance and monitoring (OM&M) plan.

NR 463.14(4)(4) Feed or charge weight. The owner or operator of each affected source or emission unit subject to an emission limit in kg/Mg (lb/ton) or mg/Mg (gr/ton) of feed or charge shall comply with both pars. (a) and (b).

NR 463.14(4)(a)(a) Except as provided in par. (c), install and operate a device that measures and records or otherwise determine the weight of feed or charge (or throughput) for each operating cycle or time period used in the performance test.

NR 463.14(4)(b)(b) Operate each weight measurement system or other weight determination procedure in accordance with the OM&M plan.

NR 463.14(4)(c)(c) The owner or operator may chose to measure and record aluminum production weight from an affected source or emission unit rather than feed or charge weight to an affected source or emission unit, provided that both of the following conditions are met:

NR 463.14(4)(c)1.1. The aluminum production weight, rather than feed or charge weight is measured and recorded for all emission units within a SAPU.

NR 463.14(4)(c)2.2. All calculations to demonstrate compliance with the emission limits for SAPUs are based on aluminum production weight rather than feed or charge weight.

NR 463.14(5)(5) Aluminum scrap shredder. The owner or operator of a scrap shredder with emissions controlled by a fabric filter shall operate a bag leak detection system or a continuous opacity monitor or conduct visible emissions observations.

NR 463.14(5)(a)(a) If a bag leak detection system is used to meet the monitoring requirements in s. NR 463.15, the owner or operator shall do all of the following:

NR 463.14(5)(a)1.1. Initiate corrective action within one hour of a bag leak detection system alarm and complete the corrective action procedures in accordance with the OM&M plan.

NR 463.14(5)(a)2.2. Operate each fabric filter system such that the bag leak detection system alarm does not sound more than 5% of the operating time during a 6-month block reporting period. In calculating this operating time fraction, if inspection of the fabric filter demonstrates that no corrective action is required, no alarm time shall be counted. If corrective action is required, each alarm shall be counted as a minimum of one hour. If the owner or operator takes longer than one hour to initiate corrective action, the alarm time shall be counted as the actual amount of time taken by the owner or operator to initiate corrective action.

NR 463.14(5)(b)(b) If a continuous opacity monitoring system is used to meet the monitoring requirements in s. NR 463.15, the owner or operator shall initiate corrective action within one hour of any 6-minute average reading of 5% or more opacity and complete the corrective action procedures in accordance with the OM&M plan.

NR 463.14(5)(c)(c) If visible emission observations are used to meet the monitoring requirements in s. NR 463.15, the owner or operator shall initiate corrective action within one hour of any observation of visible emissions during a daily visible emissions test and complete the corrective action procedures in accordance with the OM&M plan.

NR 463.14(6)(6) Thermal chip dryer. The owner or operator of a thermal chip dryer with emissions controlled by an afterburner shall do all of the following:

NR 463.14(6)(a)(a) Maintain the 3-hour block average operating temperature of each afterburner at or above the average temperature established during the performance test.

NR 463.14(7)(7) Scrap dryer, delacquering kiln or decoating kiln. The owner or operator of a scrap dryer, delacquering kiln or decoating kiln with emissions controlled by an afterburner and a lime-injected fabric filter shall meet pars. (a), (d) and (e) and either par. (b) or (c) as applicable:

NR 463.14(7)(a)1.1. Maintain the 3-hour block average operating temperature of each afterburner at or above the average temperature established during the performance test.

NR 463.14(7)(a)2.2. Operate each afterburner in accordance with the OM&M plan.

NR 463.14(7)(b)(b) If a bag leak detection system is used to meet the fabric filter monitoring requirements in s. NR 463.15, do both of the following:

NR 463.14(7)(b)1.1. Initiate corrective action within one hour of a bag leak detection system alarm and complete any necessary corrective action procedures in accordance with the OM&M plan.

NR 463.14(7)(b)2.2. Operate each fabric filter system such that the bag leak detection system alarm does not sound more than 5% of the operating time during a 6-month block reporting period. In calculating this operating time fraction, if inspection of the fabric filter demonstrates that no corrective action is required, no alarm time shall be counted. If corrective action is required, each alarm shall be counted as a minimum of one hour. If the owner or operator takes longer than one hour to initiate corrective action, the alarm time shall be counted as the actual amount of time taken by the owner or operator to initiate corrective action.

NR 463.14(7)(c)(c) If a continuous opacity monitoring system is used to meet the monitoring requirements in s. NR 463.15, initiate corrective action within one hour of any 6-minute average reading of 5% or more opacity and complete the corrective action procedures in accordance with the OM&M plan.

NR 463.14(7)(d)(d) Maintain the 3-hour block average inlet temperature for each fabric filter at or below the sum of the average temperature established during the performance test, plus 14°C (25°F).

NR 463.14(7)(e)(e) For a continuous injection device, maintain free-flowing lime in the hopper to the feed device at all times and maintain the lime feeder setting at the same level established during the performance test.
