NR 463.14(1)(b)(b) The owner or operator of an existing sweat furnace that meets the specifications of s. NR 463.13 (6) shall operate the sweat furnace and control equipment according to the requirements of this section on and after the compliance date established by s. NR 463.115.

NR 463.14(1)(c)(c) The owner or operator of a new sweat furnace that meets the specifications of s. NR 463.13 (6) shall operate the sweat furnace and control equipment according to the requirements of this section by March 23, 2000 or upon startup, whichever is later.

a Thermal chip dryers, scrap dryers, delacquering kilns, dross-only furnaces, in-line fluxers and group 1 furnaces including melting and holding furnaces.

c Site-specific monitoring plan. Owners and operators of group 1 furnaces without control devices shall include a section in their OM&M plan that documents work practices and pollution prevention measures, including procedures for scrap inspection, by which compliance is achieved with emission limits and process or feed parameter-based operating requirements. This plan and the testing to demonstrate adequacy of the monitoring plan shall be developed in coordination with and approved by the department.

NR 463.14(2)(2) Labeling. The owner or operator shall provide and maintain easily visible labels posted at each group 1 furnace, group 2 furnace, in-line fluxer, scrap dryer, delacquering kiln and decoating kiln that identify the applicable emission limits and means of compliance, including all of the following:

NR 463.14(2)(a)(a) The type of affected source or emission unit, such as a scrap dryer, delacquering kiln or decoating kiln, group 1 furnace, group 2 furnace or in-line fluxer.

NR 463.14(2)(b)(b) The applicable operational standards and control methods, including work practice or control device. This includes the type of charge to be used for a furnace, including clean scrap only, all scrap, or other, flux materials and addition practices, and the applicable operating parameter ranges and requirements as incorporated in the operations maintenance and monitoring plan required by s. NR 463.15 (2).

NR 463.14(2)(c)(c) The afterburner operating temperature and design residence time for a scrap dryer, delacquering kiln or decoating kiln.

NR 463.14(3)(3) Capture and collection systems. For each affected source or emission unit equipped with an add-on air pollution control device, the owner or operator shall do all of the following:

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.
