Current through Register Vol. 42, No. 9, June 28, 2024
(1) Except as otherwise required by the
				context, terms used in this Rule are defined in Rule
				335-3-1-.02 or in this paragraph
				as follows:
(a) "
Closed Vent
				System
" means a system that is not open to the atmosphere and that
				is composed of piping, connections, and, if necessary, flow indicating devices
				that transport gas or vapor from a piece or pieces of equipment to a control
				device.
(b) "
Coke
				By-Product Recovery Plant
" means any facility engaged in the
				separation and recovery of various fractions from coke oven gas, including tar,
				pitch, ammonium sulfate, naphthalene, and light oil.
(c) "
Connector
"
				means flanged, screwed, welded, or other joined fittings used to connect two
				pipe lines or a pipe line and a piece of process equipment.
(d) "
Conservation
				Vent
" means a pressure-vacuum valve installed on a napthalene
				separation unit cover that prevents the release of vapors during small changes
				in temperatures, barometric pressure, or liquid level.
(e) "
Control Device
"
				means an enclosed combustion device, vapor recovery system or flare.
(f) "
Equipment
"
				means each pump, valve, pressure relief valve, sampling connection, open-ended
				valve, and flange or connector in VOC service.
(g) "
First Attempt at
				Repair
" means taking rapid action for the purpose of stopping or
				reducing leakage of organic material to atmosphere using best
				practices.
(h) "
In Gas
				Service
" means that the piece of equipment contains process fluid
				that is in the gaseous state at operating conditions.
(i) "
In Light Liquid
				Service
" means that the piece of equipment contains or contacts a
				process fluid that is a liquid at operating conditions, one or more components
				having a vapor pressure greater than 0.3 kPa at 20° C (0.04 psia at 68°
				F), and the total concentration of the pure components, having a vapor pressure
				greater than 0.3 kPa at 20° C, is equal to or greater than 20 percent by
				weight.
(j) "
In Vacuum
				Service
" means that equipment is operating at an internal pressure
				which is at least 5 kPa (0.73 psia) below ambient pressure.
(k) "
In VOC Service
"
				means that the piece of equipment contains or contacts VOC.
(1) "
Naphthalene Separation
				Unit
" means the settling tank and associated equipment used in the
				recovery of naphthalene from the final cooler aqueous effluent.
(m) "
Open-Ended
				Valve
" means any valve, except pressure relief devices, having one
				side of the valve in contact with process fluid and one side open to the
				atmosphere, either directly or through open piping.
(n) "
Pressure
				Release
" means the emission of materials resulting from system
				pressure being greater than set pressure of the pressure relief
				device.
(o)
				"
Quarter
" means the following three-month periods:
				January through March, April through June, July through September, and October
				through December.
(p)
				"
Reference Method 21
" means Reference Method 21 of
				Appendix A of 40 CFR 60.
(q)
				"
Repaired
" means that equipment is adjusted, or
				otherwise altered, in order to eliminate a leak as indicated by one of the
				following: an instrument reading of 10,000 ppm or greater, indication of
				liquids dripping, or indication by a sensor that a seal or barrier fluid system
				has failed.
