Section NR 439.02 - DefinitionsThe definitions contained in chs. NR 400 and 407 apply to the terms used in this chapter. In addition, the following definitions apply to the terms used in this chapter:
(1) "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.(2) "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.(3) "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.(4) "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.(5) "Continuous monitoring system" means the total equipment used to sample, to analyze and to provide a permanent record of emissions or process parameters.(6) "Emission sampling train" means the apparatus used to collect a representative sample in the performance of an emission test.(8) "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.(9) "Monitoring device" means any instrument used to measure the operating parameters of a control device or process.(11) "Sampling port" means an opening through the wall of a stack or duct that is used to provide access for extraction of a sample.(12) "Sootblowing" means the cleaning of heat exchanger surfaces by the use of steam or air to dislodge accumulated material.Wis.
