					 engine.
"Demand response" means measures aimed at shifting time of
					 use of electricity from peak-use periods to times of lower demand by inducing

					 D975-10b.
"Electric generating unit" means a stationary internal
					 combustion engine that participates in a nonemergency voluntary demand response
					 program (i.e., load curtailment, demand response, peak shaving or like
					 program).
"Emergency" means a condition that arises from sudden and
					 reasonably unforeseeable events where the primary energy or power source is
					 disrupted or disconnected due to conditions beyond the control of an owner or
					 operator of a source including any of the following:
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
				  emergency where an ISO emergency is any of the following:
a. An abnormal system condition requiring
				  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 generator or generation 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 electric generating unit or
					 units, the terms and conditions in either Part IV (9VAC5-530-140 et seq.) or Part V
					 (9VAC5-530-220 ) of this chapter
					 that meet the requirements of Part II (9VAC5-530-30 et seq.) and Part III
					 (9VAC5-530-90 et seq.) of this
					 chapter and issued under the provisions of
					 9VAC5-80-1250.
"Identical affected units" means electric generating units
					 that have the same make, manufacturer, model, year, size, and fuel
					 specifications.
"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.
"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
					 (Permit Procedures) of 9VAC5-80 (Permits for Stationary Sources).
"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

				  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 two 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 period, unless an extension for start-up notification
					 as stated in
					 9VAC5-530-210 A 4 or
					 9VAC5-530-290 A 4 is approved by
					 the department. An extension request must be submitted seven days prior to the
					 end of the 30-day integration operational period.
"Tier 4 engine or equivalent" means a compression ignition
					 electric generating unit that meets Tier 4 standards of 40 CFR Part 1039 or,
					 for engines greater than 10 liters per cylinder, 40 CFR Part 1042, whether by
					 Tier 4 certification or by add-on controls to meet the applicable emission
					 standards for the model year and size of the engine.
"Virginia Air Pollution Control Law" means Chapter 13
					 (§ 10.1-1300 et seq.) of Title 10.1 of the Code of
					 Virginia.
