NR 460.09(4)(a)(a) General. Notwithstanding the requirements in this subsection or sub. (5), and except as provided in s. NR 460.11, the owner or operator of an affected source subject to reporting requirements under 40 CFR part 63 or under chs. NR 460 to 469 shall submit reports to the department in accordance with the reporting requirements in the relevant standards. NR 460.09(4)(b)(b) Reporting results of performance tests. The owner or operator of an affected source shall report the results of any performance test under s. NR 460.06 to the department. The owner or operator of an affected source shall report the results of the performance test to the department before the close of business on the 60th day following the completion of the performance test, unless specified otherwise in a relevant standard or as approved otherwise in writing by the department. The results of the performance test shall be submitted as part of the notification of compliance status required under s. NR 460.08 (8). NR 460.09(4)(c)(c) Reporting results of opacity or visible emission observations. The owner or operator of an affected source required to conduct opacity or visible emission observations by a relevant standard shall report the opacity or visible emission results, produced using Method 9 or Method 22 in Appendix A of 40 CFR part 60, incorporated by reference in s. NR 484.04 (13), or an alternative to these test methods, along with the results of the performance test required under s. NR 460.06. If no performance test is required, or if visibility or other conditions prevent the opacity or visible emission observations from being conducted concurrently with the performance test required under s. NR 460.06, the owner or operator shall report the opacity or visible emission results before the close of business on the 30th day following the completion of the opacity or visible emission observations. NR 460.09(4)(d)(d) Progress reports. The owner or operator of an affected source who is required to submit progress reports as a condition of receiving a compliance date extension under s. NR 460.05 (7) shall submit the reports to the department by the dates specified in the written compliance date extension. NR 460.09(4)(e)1.1. ‘Periodic reports.’ If actions taken by an owner or operator during a startup or shutdown of an affected source, and the startup or shutdown causes the source to exceed any applicable emission limit in the relevant emission standards, or during a malfunction of an affected source, including actions taken to correct a malfunction, are consistent with the procedures specified in the source’s startup, shutdown and malfunction plan as required in s. NR 460.05 (4) (c), the owner or operator shall state the information in a startup, shutdown and malfunction report. Actions taken to minimize emissions during startups, shutdowns and malfunctions shall be summarized in the report and may be done in checklist form. If actions taken are the same for each event, only one checklist is necessary. The report shall also include the number, duration and a brief description for each type of malfunction which occurred during the reporting period and which caused or may have caused any applicable emission limitation to be exceeded. Reports shall only be required if a startup or shutdown caused the source to exceed any applicable emission limitation in the relevant emission standards or if a malfunction occurred during the reporting period. The startup, shutdown and malfunction report shall consist of a letter, containing the name, title and signature of the owner or operator or other responsible official who is certifying its accuracy, that shall be submitted to the department semiannually, or on a more frequent basis if specified otherwise in a relevant standard or as established otherwise in the source’s part 70 permit. The startup, shutdown and malfunction report shall be delivered or postmarked by the 30th day following the end of each calendar half, or other calendar reporting period, as appropriate. If the owner or operator is required to submit excess emissions and continuous monitoring system performance, or other periodic, reports under 40 CFR part 63 or chs. NR 460 to 469, the startup, shutdown and malfunction reports required under this subsection may be submitted simultaneously with the excess emissions and continuous monitoring system performance or other reports. If startup, shutdown and malfunction reports are submitted with excess emissions and continuous monitoring system performance or other periodic reports, and the owner or operator receives approval to reduce the frequency of reporting for the latter under sub. (5), the frequency of reporting for the startup, shutdown and malfunction reports also may be reduced if the department does not object to the intended change. The procedures to implement the allowance in the preceding sentence shall be the same as the procedures specified in sub. (5) (c). NR 460.09(4)(e)2.2. ‘Immediate reports.’ Notwithstanding the allowance to reduce the frequency of reporting for periodic startup, shutdown and malfunction reports under subd. 1., any time an action taken by an owner or operator during a startup or shutdown that caused the source to exceed any applicable emission limitation in the relevant emission standards or during a malfunction, including actions taken to correct a malfunction, is not consistent with the procedures specified in the affected source’s startup, shutdown and malfunction plan, the owner or operator shall report the actions taken for that event within 2 working days after commencing actions inconsistent with the plan followed by a letter within 7 working days after the end of the event. The immediate report required under this subdivision shall consist of a telephone call or facsimile (FAX) transmission to the department within 2 working days after commencing actions inconsistent with the plan, and it shall be followed by a letter, delivered or postmarked within 7 working days after the end of the event, that contains the name, title and signature of the owner or operator or other responsible official who is certifying its accuracy, explaining the circumstances of the event, the reasons for not following the startup, shutdown and malfunction plan, describing all excess emissions or parameter monitoring exceedances or both which are believed to have occurred, or could have occurred in the case of malfunctions, and actions taken to minimize emissions in conformance with s. NR 460.05 (4) (a) 1. NR 460.09(4)(e)3.3. ‘Alternative reporting arrangements.’ Notwithstanding the requirements of subd. 2., the owner or operator may make alternative reporting arrangements, in advance, with the department. Procedures governing the arrangement of alternative reporting requirements under this subsection are specified in s. NR 460.08 (9). NR 460.09(5)(5) Additional reporting requirements for sources with continuous monitoring systems. NR 460.09(5)(a)(a) General. When more than one CEMS is used to measure the emissions from one affected source, due to multiple breechings or outlets, for example, the owner or operator shall report the results as required for each CEMS. NR 460.09(5)(b)(b) Reporting results of continuous monitoring system performance evaluations. NR 460.09(5)(b)1.1. The owner or operator of an affected source required to install a continuous monitoring system by a relevant standard shall furnish the department a copy of a written report of the results of the continuous monitoring system performance evaluation, as required under s. NR 460.07 (5), simultaneously with the results of the performance test required under s. NR 460.06, unless otherwise specified in the relevant standard. NR 460.09(5)(b)2.2. The owner or operator of an affected source using a continuous opacity monitoring system to determine opacity compliance during any performance test required under s. NR 460.06 shall furnish the department 2 or, upon request, 3 copies of a written report of the results of the continuous opacity monitoring system performance evaluation conducted under s. NR 460.07 (5). The copies shall be furnished at least 15 calendar days before the performance test required under s. NR 460.06 is conducted. NR 460.09(5)(c)(c) Excess emissions and continuous monitoring system performance report and summary report. NR 460.09(5)(c)1.1. Excess emissions and parameter monitoring exceedances are defined in relevant standards. The owner or operator of an affected source required to install a continuous monitoring system by a relevant standard shall submit an excess emissions and continuous monitoring system performance report or a summary report or both to the department semiannually, except when any of the following occur: NR 460.09(5)(c)1.b.b. The department determines on a case-by-case basis that more frequent reporting is necessary to accurately assess the compliance status of the source. NR 460.09(5)(c)1.c.c. The affected source is complying with the Performance Track provisions of s. NR 460.11, which allows less frequent reporting. NR 460.09(5)(c)2.2. Notwithstanding the frequency of reporting requirements specified in subd. 1., an owner or operator who is required by a relevant standard to submit excess emissions and continuous monitoring system performance and summary reports on a quarterly or more frequent basis may reduce the frequency of reporting for that standard to semiannual if all of the following conditions are met: NR 460.09(5)(c)2.a.a. For 1 full year, the affected source’s excess emissions and continuous monitoring system performance reports, which may be quarterly or monthly, continually demonstrate that the source is in compliance with the relevant standard. NR 460.09(5)(c)2.b.b. The owner or operator continues to comply with all recordkeeping and monitoring requirements specified in this chapter and the relevant standard. NR 460.09(5)(c)2.c.c. The department does not object to a reduced frequency of reporting for the affected source, as provided in subd. 3. NR 460.09(5)(c)3.3. The frequency of reporting of excess emissions and continuous monitoring system performance and summary reports required to comply with a relevant standard may be reduced only after the owner or operator notifies the department in writing of his or her intention to make a change and the department does not object to the intended change. In deciding whether to approve a reduced frequency of reporting, the department may review information concerning the source’s entire previous performance history during the 5-year recordkeeping period prior to the intended change, including performance test results, monitoring data, and evaluations of an owner or operator’s conformance with operation and maintenance requirements. The information may be used by the department to make a judgment about the source’s potential for noncompliance in the future. If the department disapproves the owner or operator’s request to reduce the frequency of reporting, the department shall notify the owner or operator in writing within 45 days after receiving notice of the owner or operator’s intention. The notification from the department to the owner or operator shall specify the grounds on which the disapproval is based. In the absence of a notice of disapproval within 45 days, approval is automatically granted. NR 460.09(5)(c)4.4. As soon as continuous monitoring system data indicate that the source is not in compliance with any emission limitation or operating parameter specified in the relevant standard, the frequency of reporting shall revert to the frequency specified in the relevant standard, and the owner or operator shall submit an excess emissions and continuous monitoring system performance report and summary report for the noncomplying emission points at the next appropriate reporting period following the noncomplying event. After demonstrating ongoing compliance with the relevant standard for another full year, the owner or operator may again request approval from the department to reduce the frequency of reporting for that standard, as provided for in subds. 2. and 3. NR 460.09(5)(c)5.5. All excess emissions and monitoring system performance reports and all summary reports, if required, shall be delivered or postmarked by the 30th day following the end of each calendar half or quarter, as appropriate. Written reports of excess emissions or exceedances of process or control system parameters shall include all the information required in sub. (3) (a) 2. to 8., in s. NR 460.07 (3) (g) and (h), and in the relevant standard, and they shall contain the name, title and signature of the responsible official who is certifying the accuracy of the report. When no excess emissions or exceedances of a parameter have occurred, or a continuous monitoring system has not been inoperative, out of control, repaired or adjusted, this information shall be stated in the report. NR 460.09(5)(c)6.6. As required under subds. 7. and 8., one summary report shall be submitted for the hazardous air pollutants monitored at each affected source, unless the relevant standard specifies that more than one summary report is required, such as one summary report for each hazardous air pollutant monitored. The summary report shall be entitled “Summary Report - Gaseous and Opacity Excess Emission and Continuous Monitoring System Performance” and shall contain all of the following information: NR 460.09(5)(c)6.b.b. An identification of each hazardous air pollutant monitored at the affected source. NR 460.09(5)(c)6.e.e. The emission and operating parameter limitations specified in the relevant standards.

This section contains requirements for control devices used to comply with provisions in relevant standards. These requirements apply only to affected sources covered by relevant standards referring directly or indirectly to this section or to 40 CFR 63.11. NR 460.10(2)(a)(a) Owners or operators using flares to comply with the provisions of 40 CFR part 63 or chs. NR 460 to 469 shall monitor these control devices to assure that they are operated and maintained in conformance with their designs. Applicable subparts of 40 CFR part 63 or applicable parts of chs. NR 460 to 469 will provide provisions stating how owners or operators using flares shall monitor these control devices. NR 460.10(2)(b)(b) Flares shall be steam-assisted, air-assisted or non-assisted. NR 460.10(2)(c)(c) Flares shall be operated at all times when emissions may be vented to them. NR 460.10(2)(d)(d) Flares shall be designed for and operated with no visible emissions, except for periods not to exceed a total of 5 minutes during any 2 consecutive hours. Method 22 in Appendix A of 40 CFR part 60, incorporated by reference in s. NR 484.04 (13), shall be used to determine the compliance of flares with the visible emission provisions of 40 CFR part 63 or chs. NR 460 to 469. The observation period is 2 hours and shall be used according to Method 22. NR 460.10(2)(e)(e) Flares shall be operated with a flame present at all times. The presence of a flare pilot flame shall be monitored using a thermocouple or any other equivalent device to detect the presence of a flame. NR 460.10(2)(f)(f) An owner or operator has the choice of adhering to the heat content specifications in subd. 2., and the maximum tip velocity specifications in par. (g) or (h), or adhering to the requirements in subd. 1. NR 460.10(2)(f)1.a.a. Flares shall be used that have a diameter of 3 inches or greater, are nonassisted, have a hydrogen content of 8.0% (by volume) or greater, and are designed for and operated with an exit velocity less than 37.2 m/sec (122 ft/sec) and less than the velocity Vmax, as determined by the following equation: Vmax = (XH2 - K1) * K2
where:
Vmax is the maximum permitted velocity, m/sec
K1 is the constant, 6.0 volume-percent hydrogen
K2 is the constant, 3.9 (m/sec)/volume-percent hydrogen
XH2 is the volume-percent of hydrogen, on a wet basis, as calculated by using ASTM D1946-90, incorporated by reference in s. NR 484.10 (28) NR 460.10(2)(f)2.2.
