Current through Register 2024 Notice Reg. No. 28, July 12, 2024
(a)
				  Definitions. For the purposes of this section, the definitions set forth in
				  section 93108(a) shall
				  apply unless otherwise specified below:
(1)
				  "Administrator" means the Administrator of the United States Environmental
				  Protection Agency (or the implementing agency in accordance with any delegation
				  of authority to approve alternatives from the U. S. Environmental Protection
				  Agency).
(2) "Back-draft
				  valve/chamber exhaust stream" is the air stream which results from collection
				  of ethylene oxide-contaminated air which may be removed from the sterilizer
				  through a back-draft valve or rear chamber exhaust system during unloading of
				  the sterilized materials.
(3)
				  "Baseline temperature" means the range of temperatures at the outlet point of a
				  catalytic oxidation control device or at the exhaust point from the combustion
				  chamber for a thermal oxidation control device established during the
				  performance test at which the unit achieves at least 99 percent control of
				  ethylene oxide emissions.
(4)
				  "Manifolding emissions" means combining ethylene oxide emissions from two or
				  more vent types for the purpose of controlling these emissions with a single
				  control device.
(5) "Maximum
				  ethylene glycol concentration" means the concentration of ethylene glycol in
				  the scrubber liquor of an acid-water scrubber control device established during
				  a performance test when the scrubber achieves at least 99 percent control of
				  ethylene oxide emissions.
(6)
				  "Maximum liquor tank level" means the level of scrubber liquor in the
				  acid-water scrubber liquor recirculation tank established during a performance
				  test when the scrubber achieves at least 99 percent control of ethylene oxide
				  emissions.
(7) "Modification" means
				  either
(A) any physical change in, method of
				  operation of, or addition to, an existing permit unit that requires an
				  application for a permit to construct and/or operate. Routine maintenance
				  and/or repair shall not be considered a physical change. A change in the method
				  of operation of equipment, unless previously limited by an enforceable permit
				  condition, shall not include:
1. an increase
				  in the production rate, unless such increases will cause the maximum design
				  capacity of the equipment to be exceeded; or
2. an increase in the hours of operation;
				  or,
3. a change in ownership of a
				  source; or,
(B) the
				  addition of any new permit unit at an existing source; or,
(C) the replacement of components if the
				  fixed capital cost of the components exceeds 50 percent of the fixed capital
				  cost that would be required to construct a comparable new
				  source.
(8) "Oxidation
				  temperature" means the temperature at the outlet point of a catalytic oxidation
				  device or at the exhaust point from the combustion chamber for a thermal
				  oxidation device.
(9) "Parametric
				  monitoring" means monitoring of a specific operating parameter or parameters of
				  a control device established to demonstrate that the control device is
				  operating under conditions that meet a performance
				  standard.
