"Electric utility steam generating unit" means any fossil fuel fired combustion unit of more than 25 megawatts that serves a generator that produces electricity for sale. A unit that co-generates steam and electricity and supplies more than one-third of its potential electric output capacity and more than 25 megawatts electric output to any utility power distribution system for sale shall be considered an electric utility steam generating unit.
"Emergency" means, in the context of 9VAC5-80-1580 C, a situation where immediate action on the part of a source is needed and where the timing of the action makes it impractical to meet the requirements of this article, such as sudden loss of power, fires, earthquakes, floods, or similar occurrences.
"Emissions unit" means any part of a stationary source that emits or would have the potential to emit any hazardous air pollutant.
"Enforceable as a practical matter" means that the permit contains emission limitations that are enforceable by the department and meet the following criteria:

"Federal operating permit" means a permit issued under Article 1 (9VAC5-80-50 et seq.) or Article 3 (9VAC5-80-360 et seq.) of this part.
"Federally enforceable" means all limitations and conditions that are enforceable by the administrator and citizens under the federal Clean Air Act or that are enforceable under other statutes administered by the administrator. Federally enforceable limitations and conditions include the following:
"Fixed capital cost" means the capital needed to provide all the depreciable components of an existing source.
"Fugitive emissions" means those emissions which could not reasonably pass through a stack, chimney, vent, or other functionally equivalent opening.
"Hazardous air pollutant" means any air pollutant listed in § 112(b) of the federal Clean Air Act as amended by 40 CFR Part 63, Subpart C.
"Locality particularly affected" means any locality that bears any identified disproportionate material air quality impact that would not be experienced by other localities.
"MACT standard" means (i) an emission standard; (ii) an alternative emission standard; or (iii) an alternative emission limitation promulgated in 40 CFR Part 63 that applies to the stationary source, the group of stationary sources, or the portion of a stationary source regulated by such standard or limitation. A MACT standard may include or consist of a design, equipment, work practice, or operational requirement, or other measure, process, method, system, or technique, including prohibition of emissions, that the administrator establishes for new or existing sources to which such standard or limitation applies. Every MACT standard established pursuant to § 112 of the federal Clean Air Act includes subpart A of 40 CFR Part 63 and all applicable appendices of 40 CFR Part 63 or of other parts of Title 40 of the Code of Federal Regulations that are referenced in that standard.
"Major process or production unit" means any process or production unit which in and of itself emits or has the potential to emit 10 tons per year of any hazardous air pollutant or 25 tons per year of any combination of hazardous air pollutants.
"Major source" means any stationary source or group of stationary sources located within a contiguous area and under common control that emits or has the potential to emit considering controls, in the aggregate, 10 tons per year or more of any hazardous air pollutant or 25 tons per year or more of any combination of hazardous air pollutants, unless the department establishes a lesser quantity, or in the case of radionuclides, different criteria from those specified in this definition.
"Maximum achievable control technology (MACT) emission limitation" means the emission limitation that is not less stringent than the emission limitation achieved in practice by the best controlled similar source and that reflects the maximum degree of reduction in emissions that the department, taking into consideration the cost of achieving such emission reduction and any nonair quality health and environmental impacts and energy requirements, determines is achievable by the constructed or reconstructed major source.
"New source review program" means a program for the preconstruction review and permitting of new stationary sources or expansions to existing ones in accordance with regulations promulgated to implement the requirements of §§ 110(a)(2)(C), 165 (relating to permits in prevention of significant deterioration areas) and 173 (relating to permits in nonattainment areas) and 112 (relating to permits for hazardous air pollutants) of the federal Clean Air Act.
"Permit" means a document issued pursuant to this article containing all federally enforceable conditions necessary to enforce the application and operation of any maximum achievable control technology or other control technologies such that the MACT emission limitation is met.
"Potential to emit" means the maximum capacity of a stationary source to emit a pollutant under its physical and 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 its design only if the limitation or its effect on emissions is state and federally enforceable.
"Presumptive MACT" means a preliminary MACT determination made by EPA, in consultation with states and other stakeholders, after data on a source category's emissions and controls have been collected and analyzed, but before the MACT standard has been promulgated.
"Process or production unit" means any collection of structures or equipment or both, that processes, assembles, applies, or otherwise uses material inputs to produce or store an intermediate or final product. A single facility may contain more than one process or production unit.
"Public comment period" means a time during which the public shall have the opportunity to comment on the permit application information, exclusive of confidential information, the preliminary review and analysis, and the preliminary decision of the department regarding the permit application.
"Reconstruct a major source" means to replace components at an existing major process or production unit whenever:
"Reconstruction" means the replacement of components at an existing major process or production unit whenever:
"Research and development activities" means activities conducted at a research or laboratory facility whose primary purpose is to conduct research and development into new processes and products, where such source is operated under the close supervision of technically trained personnel and is not engaged in the manufacture of products for sale or exchange for commercial profit, except in a de minimis manner.
"Similar source" means a stationary source or process that has comparable emissions and is structurally similar in design and capacity to a constructed or reconstructed major source such that the source could be controlled using the same control technology.
"Source category list" means the list and schedule issued pursuant to § 112(c) and (e) for promulgating MACT standards issued pursuant to § 112(d) of the federal Clean Air Act and published in the Federal Register at 63 FR 7155, February 12, 1998.
"State enforceable" means all limitations and conditions that are enforceable as a practical matter, including those requirements developed pursuant to 9VAC5-170-160, requirements within any applicable order or variance, and any permit requirements established pursuant to this chapter.
"Stationary source" means any building, structure, facility, or installation that emits or may emit any air pollutant.
"Uncontrolled emission rate" means the emission rate from a source when operating at maximum capacity without air pollution control equipment. Air pollution control equipment is equipment that enables the source to conform to applicable air pollution control laws and regulations and that is not vital to its operation.
