NR 463.16(2)(a)(a) Following the review and evaluation of the site-specific test plan, the owner or operator shall demonstrate initial compliance with each applicable emission, equipment, work practice or operational standard for each affected source and emission unit, and report the results in the notification of compliance status report as described in s. NR 463.17 (2). The owner or operator of any existing affected source for which an initial performance test is required to demonstrate compliance shall conduct this initial performance test no later than the date for compliance established by s. NR 463.115 (1). The owner or operator of any new affected source for which an initial performance test is required shall conduct this initial performance test within 90 days after the date for compliance established by s. NR 463.115 (2). Except for the date by which the performance test shall be conducted, the owner or operator shall conduct each performance test in accordance with the requirements and procedures in s. NR 460.06 (2). Owners or operators of affected sources located at facilities which are area sources are subject only to those performance testing requirements pertaining to D&F. Owners or operators of sweat furnaces meeting the specifications of s. NR 463.13 (6) are not required to conduct a performance test.

NR 463.16(2)(b)(b) The owner or operator shall conduct each test while the affected source or emission unit is operating at the highest production level with charge materials representative of the range of materials processed by the unit and, if applicable, at the highest reactive fluxing rate.

NR 463.16(2)(c)(c) Each performance test for a continuous process shall consist of 3 separate runs; pollutant sampling for each run shall be conducted for the time period specified in the applicable method or, in the absence of a specific time period in the test method, for a minimum of 3 hours.

NR 463.16(2)(d)(d) Each performance test for a batch process shall consist of 3 separate runs; pollutant sampling for each run shall be conducted over the entire process operating cycle.

NR 463.16(2)(e)(e) Where multiple affected sources or emission units are exhausted through a common stack, pollutant sampling for each run shall be conducted over a period of time during which all affected sources or emission units complete at least one entire process operating cycle or for 24 hours, whichever is shorter.

NR 463.16(2)(f)(f) Initial compliance with an applicable emission limit or standard is demonstrated if the average of 3 runs conducted during the performance test is less than or equal to the applicable emission limit or standard.

NR 463.16(3)(a)(a) Method 1 for sample and velocity traverses.

NR 463.16(3)(b)(b) Method 2 for velocity and volumetric flow rate.

NR 463.16(3)(c)(c) Method 3 for gas analysis.

NR 463.16(3)(d)(d) Method 4 for moisture content of the stack gas.

NR 463.16(3)(e)(e) Method 5 for the concentration of PM.

NR 463.16(3)(f)(f) Method 9 for visible emission observations.

NR 463.16(3)(g)(g) Method 23 for the concentration of D&F.

NR 463.16(3)(h)(h) Method 25A for the concentration of THC, as propane.

NR 463.16(3)(i)(i) Method 26A for the concentration of HCl. Where a lime-injected fabric filter is used as the control device to comply with the 90% reduction standard, the owner or operator shall measure the fabric filter inlet concentration of HCl at a point before lime is introduced to the system.

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(6)(a)(a) The tested emission unit uses feed materials and charge rates which are comparable to the emission units that it represents.

NR 463.16(6)(b)(b) The tested emission unit uses the same type of flux materials in the same proportions as the emission units it represents.

NR 463.16(6)(c)(c) The tested emission unit is operated utilizing the same work practices as the emission units that it represents.

NR 463.16(6)(d)(d) The tested emission unit is of the same design as the emission units that it represents.

NR 463.16(6)(e)(e) The tested emission unit is tested under the highest load or capacity reasonably expected to occur for any of the emission units that it represents.

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:
