NR 463.16(5)(5) Repeat tests. The owner or operator of new or existing affected sources and emission units located at secondary aluminum production facilities that are major sources shall conduct a performance test every 5 years following the initial performance test.

NR 463.16(6)(6) Testing of representative emission units. With the prior approval of the department, an owner or operator may utilize emission rates obtained by testing a particular type of group 1 furnace which is not controlled by any add-on control device, or by testing an in-line flux box which is not controlled by any add-on control device, to determine the emission rate for other units of the same type at the same facility. Emission test results may only be considered to be representative of other units if all of the following criteria are satisfied:

NR 463.16(7)(7) Establishment of monitoring and operating parameter values. The owner or operator of new or existing affected sources and emission units shall establish a minimum or maximum operating parameter value, or an operating parameter range, for each parameter to be monitored as required by s. NR 463.15 that ensures compliance with the applicable emission limit or standard. To establish the minimum or maximum value or range, the owner or operator shall use the appropriate procedures in this section and submit the information required by s. NR 463.17 (2) (d) in the notification of compliance status report. The owner or operator may use existing data in addition to the results of performance tests to establish operating parameter values for compliance monitoring provided each of the following conditions are met to the satisfaction of the department:

NR 463.16(7)(c)(c) The owner or operator certifies that no design or work practice changes have been made to the source, process or emission control equipment since the time of the report.

NR 463.16(7)(d)(d) All process and control equipment operating parameters required to be monitored were monitored as required in this subchapter and documented in the test report.

NR 463.16(8)(8) Testing of commonly-ducted units within a secondary aluminum processing unit. When group 1 furnaces and in-line fluxers are included in a single existing SAPU or new SAPU, and the emissions from more than one emission unit within that existing SAPU or new SAPU are manifolded to a single control device, compliance for all units within the SAPU is demonstrated if the total measured emissions from all controlled and uncontrolled units in the SAPU do not exceed the emission limits calculated for that SAPU based on the applicable equation in s. NR 463.13 (11).

NR 463.16(9)(9) Testing of commonly-ducted units not within a secondary aluminum processing unit. With the prior approval of the department, an owner or operator may do combined performance testing of 2 or more individual affected sources or emission units which are not included in a single existing SAPU or new SAPU, but whose emissions are manifolded to a single control device. Any performance testing of commonly-ducted units shall satisfy all the following basic requirements:

NR 463.16(9)(a)(a) All testing shall be designed to verify that each affected source or emission unit individually satisfies all emission requirements applicable to that affected source or emission unit.

NR 463.16(9)(b)(b) All emissions of pollutants subject to a standard shall be tested at the outlet from each individual affected source or emission unit while operating under the highest load or capacity reasonably expected to occur, and prior to the point that the emissions are manifolded together with emissions from other affected sources or emission units.

NR 463.16(9)(c)(c) The combined emissions from all affected sources and emission units which are manifolded to a single emission control device shall be tested at the outlet of the emission control device.

NR 463.16(9)(d)(d) All tests at the outlet of the emission control device shall be conducted with all affected sources and emission units whose emissions are manifolded to the control device operating simultaneously under the highest load or capacity reasonably expected to occur.

NR 463.16(9)(e)(e) For purposes of demonstrating compliance of a commonly-ducted unit with any emission limit for a particular type of pollutant, the emissions of that pollutant by the individual unit shall be presumed to be controlled by the same percentage as total emissions of that pollutant from all commonly-ducted units are controlled at the outlet of the emission control device.

NR 463.16 HistoryHistory: CR 04-023: cr. Register December 2008 No. 636, eff. 1-1-09; correction in (2) (a) made under s. 13.92 (4) (b) 7., Stats., Register December 2008 No. 636.

NR 463.163(1)(1) Aluminum scrap shredder. The owner or operator shall conduct performance tests to measure PM emissions at the outlet of the control system. If visible emission observations is the selected monitoring option, the owner or operator shall record visible emission observations from each exhaust stack for all consecutive 6-minute periods during the PM emission test according to the requirements of Method 9 in Appendix A to 40 CFR part 60, incorporated by reference in s. NR 484.04 (13).

NR 463.163(2)(2) Thermal chip dryer. The owner or operator shall conduct a performance test to measure THC and D&F emissions at the outlet of the control device while the unit processes only unpainted aluminum chips.

NR 463.163(3)(3) Scrap dryer, delacquering kiln and decoating kiln.

NR 463.163(3)(b)(b) If the scrap dryer, delacquering kiln or decoating kiln is subject to the alternative emission limits in s. NR 463.13 (5), the average afterburner operating temperature in each 3-hour block period shall be maintained at or above 760°C (1400°F) for the test.

NR 463.163(3)(c)(c) The owner or operator of a scrap dryer, delacquering kiln or decoating kiln subject to the alternative limits in s. NR 463.13 (5) shall submit a written certification in the notification of compliance status report containing the information required by s. NR 463.17 (2) (g).
