Contents
Subpart BBBB_Emission Guidelines and Compliance Times for Small
Municipal Waste Combustion Units Constructed on or Before August 30,
1999
Sec. 60.1940 What definitions must I know?
Terms used but not defined in this section are defined in the CAA
and in subparts A and B of this part.
Administrator means the Administrator of the U.S. Environmental
Protection Agency or his/her authorized representative or the
Administrator of a State Air Pollution Control Agency.
Air curtain incinerator means an incinerator that operates by
forcefully projecting a curtain of air across an open chamber or pit in
which combustion occurs. Incinerators of that type can be constructed
above or below ground and with or without refractory walls and floor.
Batch municipal waste combustion unit means a municipal waste
combustion unit designed so it cannot combust municipal solid waste
continuously 24 hours per day because the design does not allow waste to
be fed to the unit or ash to be removed during combustion.
Calendar quarter means three consecutive months (nonoverlapping)
beginning on: January 1, April 1, July 1, or October 1.
Calendar year means 365 (or 366 consecutive days in leap years)
consecutive days starting on January 1 and ending on December 31.
Chief facility operator means the person in direct charge and
control of the operation of a municipal waste combustion unit. That
person is responsible for daily onsite supervision, technical direction,
management, and overall performance of the municipal waste combustion
unit.
Class I units mean small municipal waste combustion units subject to
this subpart that are located at municipal waste combustion plants with
an aggregate plant combustion capacity greater than 250 tons per day of
municipal solid waste. See the definition in this section of ``municipal
waste combustion plant capacity'' for specification of which units at a
plant site are included in the aggregate capacity calculation.
Class II units mean small municipal combustion units subject to this
subpart that are located at municipal waste combustion plants with
aggregate plant combustion capacity less than or equal to 250 tons per

railroad ties and telephone poles) that are exempt from the definition
of ``municipal solid waste'' in this section.
Co-fired combustion unit means a unit that combusts municipal solid
waste with nonmunicipal solid waste fuel (for example, coal, industrial
process waste). To be considered a co-fired combustion unit, the unit
must be subject to a federally enforceable permit that limits it to
combusting a fuel feed stream which is 30 percent or less (by weight)
municipal solid waste as measured each calendar quarter.
Continuous burning means the continuous, semicontinuous, or batch
feeding of municipal solid waste to dispose of the waste, produce
energy, or provide heat to the combustion system in preparation for
waste disposal or energy production. Continuous burning does not mean
the use of municipal solid waste solely to thermally protect the grate
or hearth during the startup period when municipal solid waste is not
fed to the grate or hearth.
Continuous emission monitoring system means a monitoring system that
continuously measures the emissions of a pollutant from a municipal

First calendar half means the period that starts on January 1 and
ends on June 30 in any year.
Fluidized bed combustion unit means a unit where municipal waste is

remain in the primary combustion zone or may be carried out of the
primary combustion zone and returned through a recirculation loop.

load capability and are measured downstream of all air pollution control
devices. Load restrictions based on permits or other nonphysical
operational restrictions cannot be considered in the determination.

municipal waste combustion unit that combusts municipal solid waste, is
not field-erected, and has multiple combustion chambers in which the
primary combustion chamber is designed to operate at substoichiometric
