Current through June 24, 2024
The owner or operator of a source conducting continuous
			  emission monitoring under s.
			  NR
			  439.095 shall use the methods and procedures listed in
			  this section to install, calibrate, maintain and operate a continuous emissions
			  monitoring system, or other methods and procedures approved, in writing, by the
			  department:
(1) Continuous emissions
			monitoring systems for measuring opacity shall comply with all the provisions
			and requirements in Performance Specification 1 in 40 CFR part 60, Appendix B,
			incorporated by reference in s.
			NR
			484.04(21).
(2) Continuous emissions monitoring systems
			for measuring sulfur dioxide or nitrogen oxides shall comply with all the
			provisions and requirements in Performance Specification 2 in 40 CFR part 60,
			Appendix B or, for affected units, the performance specifications in 40 CFR
			part 75, Appendices A to I, incorporated by reference in s.
			NR
			484.04(21) and (27).
(3) Continuous emissions monitoring systems
			for measuring oxygen or carbon dioxide shall comply with all the provisions and
			requirements in Performance Specification 3 in 40 CFR part 60, Appendix B or,
			for affected units, the performance specifications in 40 CFR part 75,
			Appendices A to I, incorporated by reference in s.
			NR
			484.04(21) and (27).
(4) Continuous emissions monitoring systems
			for measuring carbon monoxide shall comply with all the provisions and
			requirements in Performance Specification 4 in 40 CFR part 60, Appendix B,
			incorporated by reference in s.
			NR
			484.04(21).
(5) Continuous emissions monitoring systems
			for measuring total reduced sulfur shall comply with all the provisions and
			requirements in Performance Specification 5 in 40 CFR part 60, Appendix B,
			incorporated by reference in s.
			NR
			484.04(21).
(6) Continuous emission rate monitoring
			systems shall comply with all the provisions and requirements in Performance
			Specification 6 in 40 CFR part 60, Appendix B, incorporated by reference in s.
			NR
			484.04(21).
(7) Continuous emissions monitoring systems
			for measuring hydrogen sulfide shall comply with all the provisions and
			requirements in Performance Specification 7 in 40 CFR part 60, Appendix B,
			incorporated by reference in s.
			NR
			484.04(21).
(7m) Continuous emissions monitoring systems
			for measuring VOCs shall comply with all the provisions and requirements in the
			department's approval issued under s.
			NR
			439.095(1).
(8) The owner or operator of a continuous
			emissions monitoring system shall comply with the quality control and quality
			assurance plan submitted by the owner or operator of the source and approved by
			the department.
(9) Continuous
			emissions monitoring systems shall meet the following minimum frequency of
			operation requirements:
(a) Opacity monitors
			shall complete one cycle of sampling and analyzing for each successive
			10-second period and one cycle of data recording for each successive 6-minute
			period.
(b) Sulfur dioxide,
			nitrogen oxides, oxygen, carbon dioxide, carbon monoxide, hydrogen sulfide,
			total reduced sulfur and VOC monitors shall complete one cycle of sampling,
			analyzing and data recording for each successive 15-minute period. The values
			recorded shall be averaged hourly. Hourly averages shall be computed from 4
			data points equally spaced over each 1 hour period, except during periods when
			calibration, quality assurance or maintenance activities are being performed.
			During these periods, a valid hour shall consist of at least 2 data points
			separated by a minimum of 15 minutes.
