NR 460.07(6)(b) (b) Disputed results. If the department finds reasonable grounds to dispute the results obtained by an alternative monitoring method, requirement or procedure, the department may require the use of a method, requirement or procedure specified in this section or in the relevant standard. If the results of the specified and alternative method, requirement or procedure do not agree, the results obtained by the specified method, requirement or procedure shall prevail.

NR 460.07(6)(c) (c) Request to use alternative monitoring procedure.

NR 460.07(6)(c)1. 1. An owner or operator who wishes to use an alternative monitoring procedure shall submit an application to the department as described in subd. 2. The application may be submitted at any time provided that the monitoring procedure is not the performance test method used to demonstrate compliance with a relevant standard or other requirement. If the alternative monitoring procedure will serve as the performance test method that is to be used to demonstrate compliance with a relevant standard, the application shall be submitted at least 60 days before the performance evaluation is scheduled to begin and shall meet the requirements for an alternative test method under s. NR 460.06 (5).

NR 460.07(6)(c)2. 2. The application shall contain a description of the proposed alternative monitoring system which addresses the 4 elements contained in the definition of monitoring in s. NR 460.02 (24w) and a performance evaluation test plan, if required, as specified in sub. (5) (c). In addition, the application shall include information justifying the owner or operator’s request for an alternative monitoring procedure, such as the technical or economic infeasibility, or the impracticality, of the affected source using the required method.

NR 460.07(6)(c)3. 3. The owner or operator may submit the information required in this subsection well in advance of the submittal dates specified in subd. 1. to ensure a timely review by the department in order to meet the compliance demonstration date specified in this section or the relevant standard.

NR 460.07(6)(c)4. 4. Application for minor changes to monitoring procedures, as specified in sub. (2) (a), may be made in the site-specific performance evaluation plan.

NR 460.07(6)(d) (d) Approval of request to use alternative monitoring procedure.

NR 460.07(6)(d)1. 1. The department shall notify the owner or operator of approval or intention to deny approval of the request to use an alternative monitoring procedure within 30 calendar days after receipt of the original request and within 30 calendar days after receipt of any supplementary information that is submitted. If a request for a minor change is made in conjunction with the site-specific performance evaluation plan, approval of the plan shall constitute approval of the minor change. Before disapproving any request to use an alternative monitoring method, the department shall notify the applicant of the department’s intention to disapprove the request together with all of the following:

NR 460.07(6)(d)1.a. a. Notice of the information and findings on which the intended disapproval is based.

NR 460.07(6)(d)1.b. b. Notice of opportunity for the owner or operator to present additional information to the department before final action on the request. At the time the department notifies the applicant of its intention to disapprove the request, the department shall specify how much time the owner or operator will have after being notified of the intended disapproval to submit the additional information.

NR 460.07(6)(d)2. 2. The department may establish general procedures and criteria in a relevant standard to accomplish the requirements of subd. 1.

NR 460.07(6)(d)3. 3. If the department approves the use of an alternative monitoring method for an affected source under subd. 1., the owner or operator of the source shall continue to use the alternative monitoring method until he or she receives approval from the department to use another monitoring method as allowed under this subsection.

NR 460.07(6)(e) (e) Alternative to the relative accuracy test. An alternative to the relative accuracy test for CEMS specified in a relevant standard may be requested as follows:

NR 460.07(6)(e)1. 1. An alternative to the test method for determining relative accuracy is available for affected sources with emission rates demonstrated to be less than 50% of the relevant standard. The owner or operator of an affected source may petition the department under subd. 2. to substitute the relative accuracy test in section 7 of Performance Specification 2 in Appendix B of 40 CFR part 60, incorporated by reference in s. NR 484.04 (21), with the procedures in section 10 if the results of a performance test conducted according to the requirements in s. NR 460.06, or other tests performed following the criteria in s. NR 460.06, demonstrate that the emission rate of the pollutant of interest in the units of the relevant standard is less than 50% of the relevant standard. For affected sources subject to emission limitations expressed as control efficiency levels, the owner or operator may petition the department to substitute the relative accuracy test with the procedures in section 10 of Performance Specification 2 if the control device exhaust emission rate is less than 50% of the level needed to meet the control efficiency requirement. The alternative procedures do not apply if the CEMS is used continuously to determine compliance with the relevant standard.

NR 460.07(6)(e)2. 2. The petition to use an alternative to the relative accuracy test shall include a detailed description of the procedures to be applied, the location and the procedure for conducting the alternative, the concentration or response levels of the alternative relative accuracy materials, and the other equipment checks included in the alternative procedures. The department shall review the petition for completeness and applicability. The department’s determination to approve an alternative shall depend on the intended use of the CEMS data and may require specifications more stringent than in Performance Specification 2.

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.
