NR 439.06 NR 439.06 Methods and procedures for determining compliance with emission limitations (by air contaminant). When tests or a continuous monitoring system are required by the department, the owner or operator of a source shall use the reference methods listed in this section and in ss. NR 439.07 to 439.095 to determine compliance with emission limitations, unless an alternative or equivalent method is approved, or a specific method is required, in writing, by the department. Any alternative, equivalent or other specific method approved or required by the department for an ozone precursor shall be submitted to, and will not become effective for federal purposes until approved by, the administrator or designee as a source-specific revision to the department’s state implementation plan for ozone. The test methods shall include quality control and quality assurance procedures and the data reporting format which are specified and approved by the department for collection, analysis, processing and reporting of compliance monitoring data. Notwithstanding the compliance determination methods which the owner or operator of a source is authorized to use under this chapter, the department may use any relevant information or appropriate method to determine a source’s compliance with applicable emission limitations.

NR 439.06(1) (1) Nonfugitive particulate emissions. The owner or operator of a source shall use Method 5, 5A, 5B, 5D, 5E, 5F, 5G, 5H, 5I, or 17 in 40 CFR part 60, Appendix A, incorporated by reference in s. NR 484.04 (13), and when required, Method 202 in 40 CFR part 51, Appendix M, incorporated by reference in s. NR 484.04 (9), to determine compliance with a nonfugitive particulate emission limitation.

NR 439.06(1m) (1m) Nonfugitive PM10 particulate emissions. The owner or operator of a source shall use Method 201 or 201A in 40 CFR part 51, Appendix M, incorporated by reference in s. NR 484.04 (9), to determine compliance with a nonfugitive PM10 particulate emission limitation.

NR 439.06(3) (3) Organic compound emissions. The owner or operator of a source shall use the test methods and procedures listed in this subsection to determine compliance with an organic compound emission limitation. If a test method inadvertently measures compounds which are listed in s. NR 400.02 (162) as having negligible photochemical reactivity, the owner or operator may exclude these compounds when determining compliance with a VOC emission limit if the amount of these compounds is accurately quantified and the exclusion is approved by the department. As a precondition to excluding these compounds as VOC or at any subsequent time, the department may require an owner or operator to provide monitoring or testing methods and results demonstrating, to the satisfaction of the department, the amount of negligibly reactive compounds in the source’s emissions. Unless a source achieves compliance through an averaging method specifically authorized by the department, organic compound emission limitations in chs. NR 419 to 424 shall be achieved on an instantaneous basis.

NR 439.06(3)(a) (a) Method 18, 25, 25A, or 25B in 40 CFR part 60, Appendix A, incorporated by reference in s. NR 484.04 (13), shall be used to determine organic compound emission concentrations or emission rates.

NR 484.04 (9) and (24), shall be used to determine the capture efficiency of a control system for volatile organic compound emissions. The reporting and recordkeeping recommendations within a test method shall be followed unless alternative reporting or recordkeeping provisions have been approved in writing by the department. When determining the overall emission reduction efficiency of a volatile organic compound control system, simultaneous measurements of both the capture efficiency of the system and the pollutant reduction efficiency of the control device may be required.

NR 484.04 (13), shall be used to determine the organic solvent content, the volume of solids, the weight of solids, the water content and the density of surface coatings, inks, and cleaning materials.

NR 484.04 (13), shall be used to determine compliance with the aerosol can filling VOC emission limit in s. NR 424.04. If a flame ionization detector is used to test compliance with s. NR 424.04, test equipment calibration shall be conducted with propane. During the testing procedure, the flame ionization detector shall continuously measure VOC emissions for a minimum of one hour per aerosol can filling line with the control device not in operation and for a minimum of one hour with the control device in full operation. Production data taken concurrently with the testing procedure shall be used to calculate the VOC emission rates for the tested aerosol can filling line when the control device is not in operation and when the control device is in full operation.

NR 439.06(3)(h) (h) Compounds identified in s. NR 400.02 (162) as having negligible photochemical reactivity shall be treated as water to determine compliance with emission limitations which refer to water.

If a continuous sootblowing system is not operating during the test, the representative average pounds of particulate emissions per million Btu heat input shall be determined by the following equation:

E = Es ((A + B) S/AR) + Ens((R - S)/R - (BS/AR))

where:
