Section NR 463.16 - Performance test and compliance demonstration general requirements(1) SITE-SPECIFIC TEST PLAN. Prior to conducting any performance test required by this subchapter, the owner or operator shall prepare a site-specific test plan which satisfies all of the requirements of this section, and shall obtain review and evaluation of the plan by the department pursuant to the procedures in s. NR 460.06.(2) INITIAL PERFORMANCE TEST. (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.(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.(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.(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.(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.(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.(3) TEST METHODS. The owner or operator shall use the following methods in Appendix A to 40 CFR part 60, incorporated by reference in s. NR 484.04(13), to determine compliance with the applicable emission limits or standards: (a) Method 1 for sample and velocity traverses.(b) Method 2 for velocity and volumetric flow rate.(c) Method 3 for gas analysis.(d) Method 4 for moisture content of the stack gas.(e) Method 5 for the concentration of PM.(f) Method 9 for visible emission observations.(g) Method 23 for the concentration of D&F.(h) Method 25A for the concentration of THC, as propane.(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.(4) ALTERNATIVE METHODS. The owner or operator may use an alternative test method, subject to approval by the department.(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.(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: (a) The tested emission unit uses feed materials and charge rates which are comparable to the emission units that it represents.(b) The tested emission unit uses the same type of flux materials in the same proportions as the emission units it represents.(c) The tested emission unit is operated utilizing the same work practices as the emission units that it represents.(d) The tested emission unit is of the same design as the emission units that it represents.(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.(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: (a) The complete emission test report used as the basis of the parameter or parameters is submitted.(b) The same test methods and procedures as required by this subchapter were used in the test.(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.(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.(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).(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: (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.(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.(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.(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.(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.Wis.
