Affected Source
-the collection of
					 equipment, activities, or both within a single contiguous area and under common
					 control that is included in a section 112(c) source category or subcategory for
					 which a section 112(d) standard or other relevant standard is established
					 pursuant to section 112 of the federal Clean Air Act.
Affected
					 source
may be further defined by the relevant standard.
Alternative Method

					 determination of compliance.
Area Source
- any stationary source that
					 is not a major source.
Certification of Compliance
- a statement
					 indicating that specific requirements under this Subchapter have been met,
					 including a description of measures used to meet such requirements.
Compliance Plan
- a description of
					 measures to be used to meet requirements under this Subchapter, including a
					 compliance schedule of dates by which such measures will be taken.
Compliance Schedule
- a sequence of events
					 leading to compliance with all requirements of this Subchapter including the
					 specified date by which the source must achieve compliance, and interim dates
					 by which all necessary milestones shall be achieved.
Continuous Monitoring System
- the total
					 equipment required under the emission monitoring sections in applicable
					 subchapters, used to sample and condition (if applicable), to analyze, and to
					 provide a permanent record of emissions or process parameters.
Control Measures
- any operating
					 procedures, abatement schemes, operational standards, or work practices used to
					 prevent or reduce air pollution.
Electric Utility Steam Generating Unit
-
					 any fossil fuel fired combustion unit of more than 25 megawatts that serves a
					 generator that produces electricity for sale. A unit that cogenerates steam and
					 electricity and supplies more than one-third of its potential electric output
					 capacity and more than 25 megawatts electrical output to any utility power
					 distribution system for sale shall be considered an electric utility steam
					 generating unit.
Existing Source
- any stationary source
					 that is not a new source.
Major Source
- any stationary source
					 (including all emission points and units of such source located within a
					 contiguous area and under common control) of air pollutants that emits, or has
					 the potential to emit, in the aggregate, 10 tons per year or more of any toxic
					 air pollutant listed in LAC 33:III.5112, Table 51.1 or 25 tons per year or more
					 of any combination of toxic air pollutants listed in LAC 33:III.5112,Table
					 51.1.
Maximum Achievable Control Technology
					 (MACT)
-
1. the maximum degree of reduction in emissions of each air
					 pollutant subject to this Subchapter (including a prohibition on such
					 emissions, where achievable) that the administrative authority, upon review of
					 submitted MACT compliance plans and other relevant information and taking into
					 consideration the cost of achieving such emission reduction, as well as any
					 non-air-quality health and environmental impacts and energy requirements,
					 determines is achievable through application of measures, processes, methods,
					 systems, or techniques including, but not limited to, measures that:
a. reduce the volume of, or eliminate emissions of such
					 pollutants through process changes, substitution of materials, or other
					 modifications; or
b. enclose systems or processes to eliminate emissions;
					 or
c. collect, capture, or treat such pollutants when released
					 from a process, stack, storage, or fugitive emissions point; or
d. are design, equipment, work practice, or operational
					 standards (including requirements for operator training or certification);
					 or
e. are a combination of the above;
2. the degree of reduction in emissions deemed achievable
					 for new sources in a category or subcategory shall not be less stringent than
					 the most stringent emissions level achieved in practice by the best controlled
					 similar source in the same category or subcategory, as determined by the
					 administrative authority upon review of submitted MACT compliance plans and
					 other relevant information, and may be more stringent where feasible;
3. emissions standards for existing sources in a category
					 or subcategory may be less stringent than standards for new sources in a
					 similar category or subcategory provided that the emissions limitation for
					 existing sources in the category or subcategory is not less stringent, and may
					 be more stringent, than:
a. for the categories or subcategories with 30 or more
					 sources, the average emission limitation achieved by the best performing 12
					 percent of the existing sources nationally in the category or subcategory;
					 or
b. for the categories or subcategories with fewer than 30
					 sources, the average emission limitation achieved by the best performing five
					 sources nationally in the category or subcategory.
Modification (Modify)
- any change in a
					 facility including, but not limited to, a physical change, a change in the
					 method of operation, or a change in the raw materials or feedstocks used for
					 products manufactured that increases or decreases the emission rate of any
					 toxic air pollutant by an amount that is greater than the minimum emission rate
					 listed for that pollutant in LAC 33:III.5112, Table 51.1, or that results in
					 the emission, at a rate greater than the minimum emission rate listed in LAC
					 33:III.5112, Table 51.1, of any toxic air pollutant not previously emitted. A
					 change in production rates (up to capacity) or hours of operation shall not be
					 considered a change in the method of operation.
New Source
- any stationary source for
					 which construction or reconstruction begins after December 20, 1991 and for
					 which the initial air quality operating permit is issued after December 20,
					 1991.
Owner or Operator
- any person who owns,
					 leases, operates, controls, or supervises a stationary source.
Permit
- written authorization by the
					 administrative authority to emit toxic air pollutants from or at a site or
					 facility, including all conditions set forth therein.
Potential to Emit
-the maximum capacity of
					 a stationary source to emit a pollutant under its physical or operational
					 design. Any physical or operational limitation on the capacity of the source to
					 emit a pollutant, including air pollution control equipment and restrictions on
					 hours of operation or on the type or amount of material combusted, stored, or
					 processed, shall be treated as part of the design if the limitation or the
					 effect it would have on emissions is specified by an existing state permit or a
					 permit issued under a program to prevent the significant deterioration of air
					 quality.
Reconstruction
- the replacement of
					 components of an existing major source to such an extent that:
1. the fixed capital cost of the new components exceeds 50
					 percent of the fixed capital cost that would be required to construct a
					 comparable entirely new source, and
2. is technologically and economically feasible for the
					 reconstructed source to meet the relevant emission standards. Upon
					 reconstruction, an affected source is subject to relevant standards for new
					 sources, including compliance dates, irrespective of any change in emissions of
					 hazardous air pollutants from that source.
Release
- accidental or intentional
					 emitting of toxic pollutants into the air.
Source Category
-a classification of
					 sources identified by EPA pursuant to section 112(c) of the Federal Clean Air
					 Act.

- a
					 scheme, plan, or set of operating procedures or practices intended to ensure
					 compliance with applicable standards.
Stationary Source
- any building,
					 structure, facility, or installation that emits or may emit any toxic air
					 pollutant designated by this Subchapter.
Toxic Air Pollutant (TAP)
