For terms not defined in this section, the definitions contained in chs

Current through June 24, 2024
NR 400 and 460 apply to the terms in this subchapter, with
					 definitions in ch. NR 460 taking precedence over definitions in ch. NR 400. If
					 this section defines a term which is also defined in ch. NR 400 or 460, the
					 definition in this section applies in this subchapter. In this
					 subchapter:
(1) "Always-controlled
				  work station" means a work station associated with a dryer from which the
				  exhaust is delivered to a control device with no provision for the dryer
				  exhaust to bypass the control device unless there is an interlock to interrupt
				  and prevent continued coating during a bypass. Sampling lines for analyzers,
				  relief valves needed for safety purposes and periodic cycling of exhaust
				  dampers to ensure safe operation are not considered bypass lines.
(2) "Applied" means the amount of organic
				  HAP, coating material or coating solids, as appropriate for the emission
				  standards in s.
				  NR
				  466.23(1) (b) used by the affected
				  source during the compliance period.
(3) "As-applied" means the condition of a
				  coating at the time of application to a substrate, including any added
				  solvent.
(4) "As-purchased" means
				  the condition of a coating as delivered to the user.
(5) "Capture efficiency" means the fraction
				  of all organic HAP emissions generated by a process that is delivered to a
				  control device, expressed as a percentage.
(6) "Capture system" means a hood, enclosed
				  room or other means of collecting organic HAP emissions into a closed-vent
				  system that exhausts to a control device.
(7) "Car-seal" means a seal that is placed on
				  a device that is used to change the position of a valve or damper, for example
				  from open to closed, in such a way that the position of the valve or damper
				  cannot be changed without breaking the seal.
(8) "Coating material" means all inks,
				  varnishes, adhesives, primers, solvents, reducers and other materials applied
				  to a substrate via a web coating line. Materials used to form a substrate are
				  not considered coating materials.
(9) "Control device" means a device such as a
				  solvent recovery device or oxidizer which reduces the organic HAP in an exhaust
				  gas by recovery or by destruction.
(10) "Control device efficiency" means the
				  ratio of organic HAP emissions recovered or destroyed by a control device to
				  the total organic HAP emissions that are introduced into the control device,
				  expressed as a percentage.
(11)
				  "Day" means a 24-consecutive-hour period.
(12) "Deviation" means any instance in which
				  an affected source subject to this subchapter or an owner or operator of an
				  affected source does any of the following:
(a) Fails to meet any requirement or
				  obligation established by this subchapter, including any emission limitation,
				  operating limit or work practice standard.
(b) Fails to meet any term or condition that
				  is adopted to implement an applicable requirement in this subchapter and that
				  is included in the operating permit for any affected source required to obtain
				  an operating permit.
(c) Fails to
				  meet any emission limitation, operating limit or work practice standard in this
				  subchapter during start-up, shutdown or malfunction, regardless of whether or
				  not the failure is permitted by this subchapter.
