This chapter applies to all air contaminant sources and to their owners and operators. For sources subject to an emission standard under chs. NR 460
or under 40 CFR part 63
, the requirements of ch. NR 460
apply in addition to the requirements of this chapter. In the case of any conflict between applicable provisions under chs. NR 460
and provisions of this chapter, the provisions under chs. NR 460
shall apply, this chapter not withstanding.
This chapter is adopted under ss. 285.11
, and 285.65
, Stats., to establish general reporting, recordkeeping, testing, inspection and determination of compliance requirements for all air contaminant sources. Individual chapters of chs. NR 400
, permits or orders may contain additional requirements.

NR 439.02 Definitions.
The definitions contained in chs. NR 400
apply to the terms used in this chapter. In addition, the following definitions apply to the terms used in this chapter:
“Audit samples" means glass vials, gas cylinders or other materials which contain a known concentration of a pollutant that may be used for the purpose of quality assurance of certain laboratory analyses required for the determination of compliance.
“Baghouse" means a control device in which dust-laden gases are forced through a fabric bag and particulates are retained by direct interception, inertial impaction, diffusion, electrostatic attraction or gravitational settling.
“Compliance emission test" means a performance test required by the department or conducted in cooperation with the department involving the quantitative measurement of air contaminants as they are emitted from a source to determine compliance with an emission limitation.
“Condensible particulate matter" means any material, except uncombined water, that may not be collected in the front half of the particulate emission sampling train but which exists as a solid or liquid at standard conditions.
“Continuous monitoring system" means the total equipment used to sample, to analyze and to provide a permanent record of emissions or process parameters.
“Emission sampling train" means the apparatus used to collect a representative sample in the performance of an emission test.
“Mechanical collector" means a broad class of particulate control devices that separate solid particles from a gas stream by a combination of mechanical forces which include centrifugal, gravitational and inertial. Such devices may include settling chambers, cyclones and multicyclone collectors.
“Monitoring device" means any instrument used to measure the operating parameters of a control device or process.
“Sampling port" means an opening through the wall of a stack or duct that is used to provide access for extraction of a sample.
“Sootblowing" means the cleaning of heat exchanger surfaces by the use of steam or air to dislodge accumulated material.

When requested by the department, a person shall furnish to the department information to locate and classify air contaminant sources according to the type, level, duration, frequency and other characteristics of emissions and such other information as may be necessary. The information shall be sufficient to evaluate the source's effect on air quality and compliance with chs. NR 400
The responsible official for a source which has been issued an operation permit under s. 285.62
, Stats., or an order under s. 285.13 (2)
, Stats., shall submit the results of monitoring required by the permit or order no less often than every 6 months, or more frequently if required by the department. In lieu of submission of all monitoring results, a summary of the monitoring results may be submitted to the department. The summary shall include sufficient data for the department to determine whether the source is in compliance with the applicable requirements to which the monitoring relates. The semiannual monitoring report may be consolidated with the quarterly excess emission report required under s. NR 439.09
when submission of both these reports is required. The department may reduce the frequency of submission of this semiannual monitoring report for non-part 70 sources. In addition to the reporting requirements under subs. (4)
, all deviations from and violations of applicable requirements shall be clearly identified in the monitoring reports.
After an operation permit has been issued to a source by the department, the responsible official for the source shall annually, or more frequently if specified in an applicable requirement or in the permit, certify the source's compliance status with the operation permit in accordance with subs. (8)
. The methods used to determine compliance status under this paragraph shall be the same methods which are required under s. NR 407.09 (1) (c) 1.
A person requested to submit information under sub. (1)
may subsequently be required to submit annually, or at such other intervals as specified by the department, reports detailing any changes in the nature of the source since the previous report and the total quantities of the air contaminants emitted.
When requested by the department, the owner or operator of a source shall submit to the department, within 60 days, a standard operating procedure which includes a detailed description of process and emission control equipment startup, operating and shutdown procedures designed to maintain compliance with emission limitations.
The owner or operator of a source shall report to the department the next business day following the onset, any malfunction or other unscheduled event at the source, not reported in advance to the department, which causes or may cause any emission limitation, including the visible emission limit, to be exceeded with the following exceptions:
Exceedances of visible emission limitations detected by a continuous emission monitor which are less than 10% opacity above the opacity limit for a period not to exceed 30 minutes. These exceedances shall be reported in the quarterly excess emissions reports required under s. NR 439.09 (10)
The person shall report the cause and duration of the exceedance, the period of time considered necessary for correction, and measures taken to minimize emissions during the period.
The owner or operator of a source which has been issued an operation permit shall report to the department by the next business day any deviation from permit requirements, the probable cause of the deviation, and any corrective actions or preventive measures taken or which will be taken to prevent future deviations.
The owner or operator of a source required to operate a continuous emission monitoring system or monitoring device shall notify the department of any shutdown, breakdown or malfunction of such device or system which is anticipated to continue in excess of one week. Notice shall occur at the next business day following the onset of the shutdown, breakdown or malfunction.
The owner or operator of a source shall report to the department in advance schedules for planned shutdown and startup of air pollution control equipment and the measures to be taken to minimize the down time of the control equipment while the source is operating. Scheduled maintenance or any other scheduled event, including startup, shutdown or sootblowing procedures which have been approved by the department under s. NR 436.03 (2) (b)
, which causes an emission limitation to be exceeded shall also be reported in advance to the department. Advance reporting under this subsection does not relieve any person from the duty to comply with any applicable emission limitation.
Any owner or operator of a coating or printing line achieving compliance by means of s. NR 422.04 (1)
shall, upon startup of the line, or upon changing the method of compliance to s. NR 422.04 (1)
, notify the department. The notification shall contain:
A description of the method by which the owner or operator will measure or calculate the volume of each coating or ink applied each day on each coating or printing line.
The responsible official required to certify the source's compliance status under sub. (1) (c)
shall include in each certification the following information:
