NR 419.02(3m)(3m) “Continuously monitor and record” means to measure data values of a parameter at least once every 15 minutes and to record either each measured data value or block average values for a 15-minute or shorter time period. A block average value is the average of all measured data values during the time period; or if data values are measured more frequently than once per minute, the average of measured data values taken at least once per minute during the time period.

NR 419.02(3s)(3s) “Control device” means any combustion device, recovery device for vapor vents, or recapture device. Control device includes absorbers, carbon adsorbers, condensers, incinerators, flares, boilers, and process heaters. A steam stripper’s primary condenser is not a control device.

NR 419.02(4)(4) “Core” means in foundry operations a separable part of a mold which is usually made of sand and is used to create openings and various cavities in the castings.

NR 419.02(5)(5) “Core binder” means any substance used to bind sand together to form a core.

NR 419.02(6)(6) “Core or mold coating” means a substance used to alter the surface of a core or mold through coating or cleaning after the core or mold has been manufactured.

NR 419.02(6m)(6m) “Cover” means a device or system which is placed on or over a waste management unit containing wastewater or residuals so that the entire surface area is enclosed to minimize emissions of affected VOC.

NR 419.02(7)(7) “Floating roof” means a storage tank cover consisting of a double deck or pontoon single deck, which rests upon and is supported by the petroleum liquid being contained, and is equipped with a closure seal or seals to seal the space between the roof edge and tank wall. The floating roof may be either a covered external floating roof in an open storage tank or an internal floating cover beneath a fixed roof.

NR 419.02(7m)(7m) “Fuel gas system” means the off-site and on-site piping and control system that gathers gaseous streams generated by on-site operations, which may be blended with other sources of gas, and transports the gaseous stream for use as fuel gas in combustion devices or in in-process combustion equipment such as furnaces and gas turbines, either singly or in combination.

NR 419.02(8)(8) “Hydrocarbon” means any organic compound containing carbon and hydrogen.

NR 419.02(8e)(8e) “Individual drain system” means the stationary system used to convey wastewater streams or residuals to a waste management unit or to discharge or disposal. “Individual drain system” includes hard-piping, all process drains and junction boxes, together with their associated sewer lines and other junction boxes, manholes, sumps, and lift stations conveying wastewater streams or residuals. A segregated storm water sewer system, which is a drain and collection system designed and operated for the sole purpose of collecting rainfall runoff at a facility, and which is segregated from all other individual drain systems, is excluded from this definition.

NR 419.02(8m)(8m) “Junction box” means any structure where sewer lines meet with one or more waste streams co-mingled.

NR 419.02(9)(9) “Landfill” has the meaning given in s. NR 500.03.

NR 419.02(10)(10) “Landspreading facility” has the meaning given in s. NR 500.03.

NR 419.02(10g)(10g) “Liquid-mounted seal” means a foam or liquid-filled seal mounted in contact with the liquid between the wall of the storage vessel or waste management unit and the floating roof with the seal mounted continuously around the circumference of the vessel or unit.

NR 419.02(10r)(10r) “Maintenance wastewater” means wastewater generated by the draining of process fluid from components in the process unit into an individual drain system prior to or during maintenance activities. Any generation of wastewater that is routine or is generated by designed manufacturing processes is not maintenance wastewater.

NR 419.02 NoteNote: Examples of activities that can generate maintenance wastewaters include descaling heat exchanger tubing bundles, cleaning distillation column traps, draining low legs and high point bleeds, draining pumps into an individual drain system and draining portions of the process unit for repair.

NR 419.02(11)(11) “Maximum theoretical emissions” means the quantity of VOC emissions that theoretically could be emitted by a stationary source without consideration of control devices based on the design capacity or maximum production capacity of the source and 8,760 hours of operation per year. In determining the maximum theoretical emissions for a source, the design capacity or maximum production capacity shall include the use of necessary coatings and inks with the highest VOC content used in practice by the source. When appropriate, and upon request by the source owner or operator, maximum theoretical emissions may be limited by the imposition of conditions in a federally enforceable permit. Such conditions shall be used in place of design capacity or maximum production capacity in calculating the maximum theoretical emissions for the source and may include, among other things, the establishment of production limitations, capacity limitations, or limitations on the VOC content of coatings or inks, or the hours of operation of any emission source, or a combination of any such limitations. Production or capacity limitations shall be established on the basis of no longer than one month and may allow for averaging for up to 12 consecutive months.

NR 419.02(11m)(11m) “Mechanical shoe seal” means metal sheets that are held vertically against the wall of the storage vessel by springs, weighted levers, or other mechanisms and connected to a floating roof by braces or other means. A flexible coated fabric spans the annular space between the metal sheet and the floating roof.
