Section III-5103 - Definitions, Units, and Abbreviations
A. The terms in this Subchapter are used as defined in LAC 33:III.111 except for those terms defined herein as follows.

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- any method of sampling and analyzing for a toxic air pollutant that is not a reference method, but that has been demonstrated to the administrative authority's satisfaction to produce results adequate for the administrative authority's 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.

Standard- any criterion or prohibition as set forth in this Subchapter to control the emission of toxic air pollutants.

Standard Operating Procedure (SOP)- 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)- any substance listed in LAC 33:III.5112, Table 51.2 or 51.3. Toxic air pollutants are listed pursuant to R.S. 30:2060 and, except for lead, do not include those pollutants for which National Ambient Air Quality Standards have been established under section 108 of the Federal Clean Air Act.

Virgin Fossil Fuel-any solid, refined solid, refined liquid, or refined or natural gaseous fossil fuel with a Btu content greater than 7,000 Btu/lb that is not blended with reprocessed or recycled fuels. Group 1 virgin fossil fuels consist of natural gas, liquid petroleum gas, distillate fuel oil, gasoline, and diesel fuel. Group 2 virgin fossil fuels consist of coal, residual fuel oil, and petroleum coke.
