Chapter NR 460

NR 460.07(6)(e)3. 3. The department shall review the permission to use an alternative to the CEMS relative accuracy test and may rescind the permission if the CEMS data from a successful completion of the alternative relative accuracy procedure indicate that the affected source’s emissions are approaching the level of the relevant standard. The criterion for reviewing the permission is that the collection of CEMS data shows that emissions have exceeded 70% of the relevant standard for any averaging period, as specified in the relevant standard. For affected sources subject to emission limitations expressed as control efficiency levels, the criterion for reviewing the permission is that the collection of CEMS data shows that exhaust emissions have exceeded 70% of the level needed to meet the control efficiency requirement for any averaging period, as specified in the relevant standard. The owner or operator of the affected source shall maintain records and determine the level of emissions relative to the criterion for permission to use an alternative for relative accuracy testing. If this criterion is exceeded, the owner or operator shall notify the department within 10 days of the occurrence and include a description of the nature and cause of the increased emissions. The department shall review the notification and may rescind permission to use an alternative and require the owner or operator to conduct a relative accuracy test of the CEMS as specified in section 7 of Performance Specification 2 in Appendix B of 40 CFR part 60, incorporated by reference in s. NR 484.04 (21).

NR 460.07(7) (7) Reduction of monitoring data.

NR 460.07(7)(a) (a) The owner or operator of each CMS shall reduce the monitoring data as specified in this subsection.

NR 460.07(7)(b) (b) The owner or operator of each COMS shall reduce all data to 6-minute averages calculated from 36 or more data points equally spaced over each 6-minute period. Data from CEMS for measurement other than opacity, unless otherwise specified in the relevant standard, shall be reduced to 1-hour averages computed from 4 or more data points equally spaced over each 1-hour period, except during periods when calibration, quality assurance or maintenance activities pursuant to provisions of 40 CFR part 63 or chs. NR 460 to 469 are being performed. During these periods, a valid hourly average shall consist of at least 2 data points with each representing a 15-minute period. Alternatively, an arithmetic or integrated 1-hour average of CEMS data may be used. Time periods for averaging are defined in s. NR 460.02.

NR 460.07(7)(c) (c) The data may be recorded in reduced or nonreduced form.

NR 460.07(7)(d) (d) All emission data shall be converted into units of the relevant standard for reporting purposes using the conversion procedures specified in that standard. After conversion into units of the relevant standard, the data may be rounded to the same number of significant digits as used in that standard to specify the emission limit.

NR 460.07(7)(e) (e) Monitoring data recorded during periods of unavoidable CMS breakdowns, out-of-control periods, repairs, maintenance periods, calibration checks and zero (low-level) and high-level adjustments may not be included in any data average computed under 40 CFR part 63 or under chs. NR 460 to 469. For owners or operators complying with the requirements of s. NR 460.09 (2) (b) 7., data averages shall include any data recorded during periods of monitor breakdown or malfunction.

The allowance in the previous sentence applies beginning one year after the stationary source is required to be in compliance with the relevant section 112 standard, or one year after the stationary source is required to be in compliance with the applicable 40 CFR part 60 or 40 CFR part 61 standard, whichever is latest. Procedures governing the implementation of this provision are specified in s. NR 460.08 (9).

NR 460.09(2) (2) General recordkeeping requirements.

NR 460.09(2)(b) (b) Recordkeeping requirements. The owner or operator of an affected source subject to the provisions of 40 CFR part 63 shall maintain relevant records for the source of all of the following:

NR 460.09(2)(b)1. 1. The occurrence and duration of each startup or shutdown when the startup or shutdown causes the source to exceed any applicable emission limitation in the relevant emission standards.
