Universal Citation: WI Admin Code § NR 463.19

Current through August 26, 2024

(1)

(a) The owner or operator shall maintain files of all information, including all reports and notifications, required by s. NR 460.09(2) and this subchapter.

(b) The owner or operator shall retain each record for at least 5 years following the date of each occurrence, measurement, maintenance, corrective action, report or record. The most recent 2 years of records shall be retained at the facility. The remaining 3 years of records may be retained off site.

(d) The owner or operator may report required information on paper or on a labeled computer disk using commonly available and department compatible computer software.

(2) In addition to the general records required by s. NR 460.09(2), the owner or operator of a new or existing affected source, including an emission unit in a secondary aluminum processing unit, shall maintain records of all of the following:

(a) For each affected source and emission unit with emissions controlled by a fabric filter or a lime-injected fabric filter each of the following as applicable:

1. If a bag leak detection system is used, the number of total operating hours for the affected source or emission unit during each 6-month reporting period, records of each alarm, the time of the alarm, the time corrective action was initiated and completed and a brief description of the cause of the alarm and the corrective actions taken.

2. If a continuous opacity monitoring system is used, records of opacity measurement data, including records where the average opacity of any 6-minute period exceeds 5%, with a brief explanation of the cause of the emissions, the time the emissions occurred, the time corrective action was initiated and completed and the corrective action taken.

3. If an aluminum scrap shredder is subject to visible emission observation requirements, records of all observations made using Method 9 in Appendix A to 40 CFR part 60, incorporated by reference in s. NR 484.04(13), including records of any visible emissions during a 30-minute daily test, with a brief explanation of the cause of the emissions, the time the emissions occurred, the time corrective action was initiated and completed and the corrective action taken.

(b) For each affected source with emissions controlled by an afterburner, both of the following:

1. Records of 15-minute block average afterburner operating temperature, including any period when the average temperature in any 3-hour block period falls below the compliant operating parameter value with a brief explanation of the cause of the excursion and the corrective action taken.

2. Records of annual afterburner inspections.

(c) For each scrap dryer, delacquering kiln or decoating kiln and group 1 furnace, subject to D&F and HCl emission standards with emissions controlled by a lime-injected fabric filter, records of 15-minute block average inlet temperatures for each lime-injected fabric filter, including any period when the 3-hour block average temperature exceeds the compliant operating parameter value +14°C (+25°F), with a brief explanation of the cause of the excursion and the corrective action taken.

(d) For each affected source and emission unit with emissions controlled by a lime-injected fabric filter, the requirements in subd. 1. and either subd. 2. or 3.:

1. Records of inspections at least once every 8-hour period verifying that lime is present in the feeder hopper or silo and flowing, including any inspection where blockage is found, with a brief explanation of the cause of the blockage and the corrective action taken, and records of inspections at least once every 4-hour period for the subsequent 3 days. If flow monitors, pressure drop sensors or load cells are used to verify that lime is present in the hopper and flowing, records of all monitor or sensor output including any event where blockage was found, with a brief explanation of the cause of the blockage and the corrective action taken.

2. If the lime feeder setting is monitored, records of daily inspections of feeder setting, including records of any deviation of the feeder setting from the setting used in the performance test, with a brief explanation of the cause of the deviation and the corrective action taken.

3. If the lime addition rate for a noncontinuous lime injection system is monitored pursuant to the approved alternative monitoring requirements in s. NR 463.15(22), records of the time and mass of each lime addition during each operating cycle or time period used in the performance test and calculations of the average lime addition rate in lb/ton of feed or charge.

(e) For each group 1 furnace, with or without add-on air pollution control devices, or in-line fluxer, records of 15-minute block average weights of gaseous or liquid reactive flux injection, total reactive flux injection rate and calculations, including records of the identity, composition and weight of each addition of gaseous, liquid or solid reactive flux, including records of any period the rate exceeds the compliant operating parameter value and corrective action taken.

(f) For each continuous monitoring system, records required by s. NR 460.09(3).

(g) For each affected source and emission unit subject to an emission standard in kg/Mg (lb/ton) of feed or charge, records of feed or charge, or throughput, weights for each operating cycle or time period used in the performance test.

(h) Approved site-specific monitoring plan for a group 1 furnace without add-on air pollution control devices with records documenting conformance with the plan.

(i) Records of all charge materials for each thermal chip dryer, dross-only furnace, and group 1 melting and holding furnaces without air pollution control devices processing only clean charge.

(j) Operating logs for each group 1 sidewell furnace with add-on air pollution control devices documenting conformance with operating standards for maintaining the level of molten metal above the top of the passage between the sidewell and hearth during reactive flux injection and for adding reactive flux only to the sidewell or a furnace hearth equipped with a control device for PM, HCl and D&F emissions.

(k) For each in-line fluxer for which the owner or operator has certified that no reactive flux was used, one of the following:

1. Operating logs which establish that no source of reactive flux was present at the in-line fluxer.

2. Labels required pursuant to s. NR 463.14(2) which establish that no reactive flux may be used at the in-line fluxer.

3. Operating logs which document each flux gas, agent or material used during each operating cycle.

(L) Records of all charge materials and fluxing materials or agents for a group 2 furnace.

(m) Records of monthly inspections for proper unit labeling for each affected source and emission unit subject to labeling requirements.

(n) Records of annual inspections of emission capture and collection and closed vent systems.

(o) Records for any approved alternative monitoring or test procedure.

(p) Current copy of all required plans, including any revisions, with records documenting conformance with the applicable plan, including all of the following:

1. Startup, shutdown and malfunction plan.

2. Operation, maintenance and monitoring (OM&M) plan.

3. Site-specific secondary aluminum processing unit emission plan, if applicable.

(q) For each secondary aluminum processing unit, records of total charge weight, or if the owner or operator chooses to comply on the basis of aluminum production, total aluminum produced for each 24-hour period and calculations of 3-day, 24-hour rolling average emissions.
