1. A failure of the electrical
				  grid.
2. On-site disaster or
				  equipment failure.
3. Public
				  service emergencies such as flood, fire, natural disaster, or severe weather
				  conditions.
4. An ISO-declared

				  manual or automatic action to maintain system frequency, to prevent loss of
				  firm load, equipment damage, or tripping of system elements that could
				  adversely affect the reliability of an electric system or the safety of persons
				  or property.
b. Capacity deficiency
				  or capacity excess conditions.
c. A
				  fuel shortage requiring departure from normal operating procedures in order to
				  minimize the use of such scarce fuel.
d. Abnormal natural events or man-made
				  threats that would require conservative operations to posture the system in a
				  more reliable state.
e. An abnormal
				  event external to the ISO service territory that may require ISO action.
"Emergency generation unit or source" means a stationary
					 internal combustion engine that operates only during an emergency, required
					 maintenance, or operability and emissions testing.
"General permit" means, for an emergency generation unit,
					 the terms and conditions in Part IV (9VAC5-540-140 et seq.) of this
					 chapter that meet the requirements of Part II (9VAC5-540-30 et seq.) and Part III
					 (9VAC5-540-90 et seq.) of this
					 chapter and issued under the provisions of
					 9VAC5-80-1250.
"Identical affected unit" means electric generating units
					 that have the same make, manufacturer, model, year, size, and fuel
					 specifications.
"Independent system operator" or "ISO" means a person who
					 may receive or has received by transfer pursuant to § 56-576 of the Code
					 of Virginia, any ownership or control of, or any responsibility to operate, all
					 or part of the transmission systems in the Commonwealth.
"Integration operational period" means that period of time
					 beginning with the first time the affected unit is started on-site and ending
					 when the affected unit is fully integrated with the source's electrical system.
					 In no case shall this period exceed 30 days.
"ISO-declared emergency" means a condition that exists when
					 the independent system operator, as defined in § 56-576 of the Code of
					 Virginia, notifies electric utilities that an emergency exists or may occur and
					 that complies with the definition of "emergency" adopted by the board.
"Kilowatt (kW) to brake horsepower (bhp)" means the
					 conversion of 1 kW = 1.341 bhp.
"Load curtailment" means an action similar to demand
					 response, with the specific removal or reduction of electrical loads for a
					 limited period of time from a utility grid system in response to a request from
					 the utility or electrical grid system operator.
"Major new source review (major NSR) program" means a
					 preconstruction review and permit program (i) for new major stationary sources
					 or major modifications (physical changes or changes in the method of
					 operation), (ii) established to implement the requirements of §§ 112,
					 165, and 173 of the federal Clean Air Act ( 42 USC §§ 7401 et seq.)
					 and associated regulations, and (iii) codified in Article 1 (9VAC5-80-50 et seq.), Article 7
					 (9VAC5-80-1400 et seq.), Article 8
					 (9VAC5-80-1605 et seq.) and Article
					 9 (9VAC5-80-2000 et seq.) of Part II

"Manufacturer certified emissions" means the emission
					 levels from a stationary compression ignition engine as identified according to
					 the manufacturers' specifications applicable to that engine's family and model
					 year.
"Model year" means either (i) the calendar year in which
					 the engine was originally produced or (ii) the annual new model production
					 period of the engine manufacturer if it is different than the calendar year.
					 This must include January 1 of the calendar year for which the model year is
					 named. It may not begin before January 2 of the previous calendar year and it
					 must end by December 31 of the named calendar year. For an engine that is
					 converted to a stationary engine after being placed into service as a nonroad
					 or other nonstationary engine, model year means the calendar year or new model
					 production period in which the engine was originally produced.
"Nonattainment area" means any area that does not meet the
					 national ambient air quality standards for any pollutant pursuant to § 107
					 of the federal Clean Air Act ( 42 USC § 7401 et seq.) and listed in
					 9VAC5-20-204.
"Operation" means the burning of fuel regardless of whether
					 electricity is generated.
"Peak shaving" means measures aimed solely at shifting time
					 of use of electricity from peak-use periods to times of lower demand by
					 inducing retail customers to curtail electricity usage during periods of
					 congestion and higher prices in the electrical grid. Peak shaving is typically
					 undertaken at a source owner's discretion in order to reduce maximum electrical
					 usage and, therefore, cost of electrical service to the source owner.
"Reference method" means any method of sampling and
					 analyzing for an air pollutant as described in the following EPA
					 regulations:
1. For ambient air
				  quality standards in 9VAC5-30 (Ambient Air Quality Standards): the applicable
				  appendix of 40 CFR Part 50 or any method that has been designated as a
				  reference method in accordance with 40 CFR Part 53, except that it does not
				  include a method for which a reference designation has been canceled in
				  accordance with 40 CFR
				  53.11 or
				  40 CFR
				  53.16;
2. For emission standards in 9VAC5-40
				  (Existing Stationary Sources) and 9VAC5-50 (New and Modified Stationary
				  Sources): Appendix M of 40 CFR Part 51 or Appendix A of 40 CFR Part 60;
				  or
3. For emission standards in
				  9VAC5-60 (Hazardous Air Pollutant Sources): Appendix B of 40 CFR Part 61 or
				  Appendix A of 40 CFR Part 63.
"Spark ignition unit" or "SI unit" means a natural gas or
					 liquefied petroleum gas fueled engine or any other type of engine with a spark
					 plug (or other sparking device) and with operating characteristics
					 significantly similar to the theoretical Otto combustion cycle. Spark ignition
					 engines usually use a throttle to regulate intake air flow to control power
					 during normal operation. Dual-fuel engines in which a liquid fuel (typically
					 diesel fuel) is used for compression ignition and gaseous fuel (typically
					 natural gas) is used as the primary fuel at an annual average ratio of less
					 than 2 parts diesel fuel to 100 parts total fuel on an energy equivalent basis
					 are spark ignition engines.
"Startup" means the date on which each affected unit
					 completes the integration operational period, unless an extension for start-up
					 notification as stated in subdivision 4 of
					 9VAC5-540-210 is approved by the
					 department. An extension request must be submitted seven days prior to the end
					 of the 30-day integration operational period.
"Virginia Air Pollution Control Law" means Chapter 13
					 (§ 10.1-1300 et seq.) of Title 10.1 of the Code of
					 Virginia.
