that is used to produce steam for purposes other than generating electricity.
An auxiliary steam boiler produces steam as a replacement for steam
produced by another piece of equipment that is not operating due to
planned or unplanned maintenance.
(4) Average activity level for fuel oil firing--The
product of an electric utility unit's maximum rated capacity for fuel
oil firing and the average annual capacity factor for fuel oil firing
for the period from January 1, 1990, to December 31, 1993.
(5) Block one-hour average--An hourly average of data,
collected starting at the beginning of each clock hour of the day
and continuing until the start of the next clock hour.
(6) Boiler--Any combustion equipment fired with solid,
liquid, and/or gaseous fuel used to produce steam or to heat water.
(7) Btu--British thermal unit.
(8) Chemical processing gas turbine--A gas turbine
that vents its exhaust gases into the operating stream of a chemical
process.
(9) Continuous emissions monitoring system (CEMS)--The
total equipment necessary for the continuous determination and recordkeeping
of process gas concentrations and emission rates in units of the applicable
emission limitation.
(10) Daily--A calendar day starting at midnight and
continuing until midnight the following day.
(11) Diesel engine--A compression-ignited two- or four-stroke
engine that liquid fuel injected into the combustion chamber ignites
when the air charge has been compressed to a temperature sufficiently
high for auto-ignition.
(12) Duct burner--A unit that combusts fuel and that
is placed in the exhaust duct from another unit (such as a stationary
gas turbine, stationary internal combustion engine, kiln, etc.) to
allow the firing of additional fuel to heat the exhaust gases.
(13) Electric generating facility (EGF)--A unit that
generates electric energy for compensation and is owned or operated
by a person doing business in this state, including a municipal corporation,
electric cooperative, or river authority.
(14) Electric power generating system--One electric
power generating system consists of either:
(A) for the purposes of Subchapter C, Divisions 1 and
4 of this chapter (relating to Beaumont-Port Arthur Ozone Nonattainment
Area Utility Electric Generation Sources; and Dallas-Fort Worth Eight-Hour
Ozone Nonattainment Area Utility Electric Generation Sources), all
boilers, auxiliary steam boilers, and stationary gas turbines (including
duct burners used in turbine exhaust ducts) at electric generating
facility (EGF) accounts that generate electric energy for compensation;
are owned or operated by an electric cooperative, municipality, river
authority, public utility, independent power producer, or a Public
Utility Commission of Texas regulated utility, or any of its successors;
and are entirely located in one of the following ozone nonattainment
areas:
(i) Beaumont-Port Arthur; or
(ii) Dallas-Fort Worth eight-hour;
(B) for the purposes of Subchapter C, Division 3 of
this chapter (relating to Houston-Galveston-Brazoria Ozone Nonattainment
Area Utility Electric Generation Sources), all boilers, auxiliary
steam boilers, and stationary gas turbines (including duct burners
used in turbine exhaust ducts) at EGF accounts that generate electric
energy for compensation; are owned or operated by an electric cooperative,
municipality, river authority, public utility, or a Public Utility
Commission of Texas regulated utility, or any of its successors; and
are entirely located in the Houston-Galveston-Brazoria ozone nonattainment
area;
(C) for the purposes of Subchapter B, Division 3 of
this chapter (relating to Houston-Galveston-Brazoria Ozone Nonattainment
Area Major Sources), all units in the Houston-Galveston-Brazoria ozone
nonattainment area that generate electricity but do not meet the conditions
specified in subparagraph (B) of this paragraph, including, but not
limited to, cogeneration units and units owned by independent power
producers; or
(D) for the purposes of Subchapter E, Division 1 of
this chapter (relating to Utility Electric Generation in East and
Central Texas), all boilers, auxiliary steam boilers, and stationary
gas turbines at EGF accounts that generate electric energy for compensation;
are owned or operated by an electric cooperative, independent power
producer, municipality, river authority, or public utility, or any
of its successors; and are located in Atascosa, Bastrop, Bexar, Brazos,
Calhoun, Cherokee, Fannin, Fayette, Freestone, Goliad, Gregg, Grimes,

(ii) the period of time that an Electric Reliability
Council of Texas, Inc. (ERCOT)-issued emergency notice or energy emergency
alert (EEA) (as defined in ERCOT Nodal Protocols,
Section 2: Definitions and Acronyms (August 13, 2014) and issued
as specified in ERCOT Nodal Protocols, Section
6: Adjustment Period and Real-Time Operations (August 13, 2014))
is applicable to the serving electric power generating system. The
emergency situation is considered to end upon expiration of the emergency
notice or EEA issued by ERCOT;
(iii) an unforeseen failure of on-site electrical transmission
equipment (e.g., a transformer);
(iv) an unforeseen failure of natural gas service;
(v) an unforeseen flood or fire, or a life-threatening
situation;
(vi) operation of emergency generators for Federal
Aviation Administration licensed airports, military airports, or manned
space flight control centers for the purposes of providing power in
anticipation of a power failure due to severe storm activity; or
(vii) operation of an emergency generator as part of
