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)

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.
