Current through Register Vol. 48, No. 6, June 28, 2024
The terms used in this regulation shall have the meanings
					 set forth in this section as follows:
(a) Account certificate of representation
				  means the completed and signed submission required by Subpart B of this
				  regulation for certifying the designation of a NOX
				  authorized account representative for a NOX Budget
				  source or a group of identified NOX Budget sources who
				  is authorized to represent the owners and operators of such source or sources
				  and of the NOX Budget units at such source or sources
				  with regard to matters under the NOX Budget
				  Program.
(b) [Reserved]
(c) [Reserved]
(d) [Reserved]
(e) Automated data acquisition and handling
				  system or DAHS means that component of the CEMS, or other emissions monitoring
				  system approved for use under Subpart H of this regulation, designed to
				  interpret and convert individual output signals from pollutant concentration
				  monitors, flow monitors, diluent gas monitors, and other component parts of the
				  monitoring system to produce a continuous record of the measured parameters in
				  the measurement units required by Subpart H of this regulation.
(f) Boiler means an enclosed fossil or other
				  fuel-fired combustion device used to produce heat and to transfer heat to
				  recirculating water, steam, or other medium.
(g) CAA means the Clean Air Act,
				  42 U.S.C.
				  7401,
et seq
., as amended by
				  Pub. L. No.
				  101-549 (November 15, 1990).
(h) Combined cycle system means a system
				  comprised of one or more combustion turbines, heat recovery steam generators,
				  and steam turbines configured to improve overall efficiency of electricity
				  generation or steam production.
(i)
				  Combustion turbine means an enclosed fossil or other fuel-fired device that is
				  comprised of a compressor, a combustor, and a turbine, and in which the flue
				  gas resulting from the combustion of fuel in the combustor passes through the
				  turbine, rotating the turbine.
(j)
				  Commence commercial operation means, with regard to a unit that serves a
				  generator, to have begun to produce steam, gas, or other heated medium used to
				  generate electricity for sale or use, including test generation. Except as
				  provided in Section
				  96.5, for a unit that is a
				  NOX Budget unit under Section
				  96.4 on the date the unit commences
				  commercial operation, such date shall remain the unit's date of commencement of
				  commercial operation even if the unit is subsequently modified, reconstructed,
				  or repowered. Except as provided in Section
				  96.5, for a unit that is not a
				  NOX Budget unit under Section
				  96.4 on the date the unit commences
				  commercial operation, the date the unit becomes a NOX
				  Budget unit under Section
				  96.4 shall be the unit's date of
				  commencement of commercial operation.
(k) Commence operation means to have begun
				  any mechanical, chemical, or electronic process, including, with regard to a
				  unit, start-up of a unit's combustion chamber. Except as provided in Section
				  96.5, for a unit that is a
				  NOX Budget unit under Section
				  96.4 on the date of commencement of
				  operation, such date shall remain the unit's date of commencement of operation
				  even if the unit is subsequently modified, reconstructed, or repowered. Except
				  as provided in Section
				  96.5, for a unit that is not a
				  NOX Budget unit under Section
				  96.4 on the date of commencement of
				  operation, the date the unit becomes a NOX Budget unit
				  under Section
				  96.4 shall be the unit's date of
				  commencement of operation.
(l)
				  Common stack means a single flue through which emissions from two or more units
				  are exhausted.
(m)
				  [Reserved]
(n) [Reserved]
(o) Continuous emission monitoring system or
				  CEMS means the equipment required under Subpart H of 40 CFR Part 75 to sample,
				  analyze, measure, and provide, by readings taken at least once every 15 minutes
				  of the measured parameters, a permanent record of nitrogen oxides emissions,
				  expressed in tons per hour for nitrogen oxides. The following systems are
				  component parts included, consistent with 40 CFR Part 75, in a continuous
				  emission monitoring system:
(1) Flow
				  monitor;
(2) Nitrogen oxides
				  pollutant concentration monitors;
(3) Diluent gas monitor (oxygen or carbon
				  dioxide) when such monitoring is required by Subpart H of this
				  regulation;
(4) A continuous
				  moisture monitor when such monitoring is required by Subpart H of this
				  regulation; and
(5) An automated
				  data acquisition and handling system.
