NR 463.18(2)(c)(c) The owner or operator shall submit the results of any performance test conducted during the reporting period, including one complete report documenting test methods and procedures, process operation and monitoring parameter ranges or values for each test method used for a particular type of emission point tested.

NR 463.18(3)(3) Annual compliance certifications. For the purpose of annual certifications of compliance required by s. NR 439.03 (1) (c), the owner or operator shall certify continuing compliance based upon, but not limited to, both of the following conditions:

NR 463.19(1)(a)(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.

NR 463.19(1)(b)(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.

NR 463.19(1)(d)(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.

NR 463.19(2)(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:

NR 463.19(2)(a)(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:

NR 463.19(2)(a)1.1. 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.

NR 463.19(2)(a)2.2. 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.

NR 463.19(2)(a)3.3. 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.

NR 463.19(2)(b)1.1. 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.

NR 463.19(2)(b)2.2. Records of annual afterburner inspections.

NR 463.19(2)(c)(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.

NR 463.19(2)(d)(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.:

NR 463.19(2)(d)1.1. 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.

NR 463.19(2)(d)2.2. 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.

NR 463.19(2)(d)3.3. 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.
