Current through July 10, 2024
(a)
Definitions.
For purposes of this section:
(1) "Affected state" means "affected states"
			 as defined in section
			 22a-174-1 of the
			 Regulations of Connecticut State Agencies.
(2) "Affected unit" means a fossil-fuel
			 fired:
(A) Stationary source that serves a
			 generator with a nameplate capacity of 15 MW or more; or
(B) Boiler or indirect heat exchanger with a
			 maximum heat input capacity of 250 MMBtu/hr or more.
(3) "Average emissions rate" means a
			 determination of the rate of SO2 emissions, measured in
			 pounds of SO2 per MMBtu, in any calendar quarter from
			 either a single affected unit or from two or more affected units. Average
			 emissions rate for a single unit is calculated by dividing the total quarterly
			 SO2 emissions, in pounds, from such unit by the total
			 quarterly heat input, in MMBtu, for such unit. Average emissions rate for two
			 or more units is calculated by dividing the total quarterly
			 SO2 emissions, in pounds, from all such units by the
			 total quarterly heat input, in MMBtu, for all such units.
(4) "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.
(5) "Calendar quarter" means the period of
			 January 1 to March 31, inclusive, April 1 to June 30, inclusive, July 1 to
			 September 30, inclusive or October 1 to December 31, inclusive.
(6) "Connecticut State
			 SO2 Retirement Account" means a general allowance
			 tracking system account established by the commissioner under
			 40 CFR
			 73.31 for the purpose of permanently holding
			 SO2 allowances retired by the owners or operators of
			 affected units in accordance with the provisions of subsection (d) of this
			 section.
(7) "Continuous emissions
			 monitoring system" or "CEMS" means any equipment used to sample, analyze and
			 measure SO2 emissions to provide a permanent record of
			 such emissions expressed in pounds per MMBtu.
(8) "Emissions unit" means "emission unit" as
			 defined in section
			 22a-174-1 of the
			 Regulations of Connecticut State Agencies.
(9) "Indirect heat exchanger" means
			 combustion equipment in which the flame or products of combustion are separated
			 from any contact with the principal material in the process by metallic or
			 refractory walls, and that emits exhaust gases only through a stack. "Indirect
			 heat exchangers" include, but are not limited to, steam boilers, vaporizers,
			 melting pots, heat exchangers, column reboilers, fractioning column feed
			 preheaters, reactor feed preheaters, pyrolysis heaters and fuel-fired
			 reactors.
(10) "MMBtu" means
			 million BTU of heat input.
(11)
			 "Retire" or "retirement" when referring to SO2
			 allowances, means the permanent withdrawal of SO2
			 allowances by the Administrator from any allowance tracking system account to
			 the Connecticut SO2 Allowance Retirement Account in an
			 amount equal to the number of tons of SO2 emitted by
			 each affected unit.
(12) "Sulfur
			 dioxide" or "SO2" means a gas that at standard
			 conditions has the molecular form SO2.
(13) "Title IV SO2
			 allowance" or "SO2 allowance" means an authorization
			 allocated to a Title IV source by the Administrator, pursuant to Title IV of
			 the federal Clean Air Act (
			 42 USC
			 7651d, et seq.) and 40 CFR Parts 72 and 73,
			 to emit up to one ton of SO2 during or after a specified
			 calendar year.
(14) "Title IV
			 source" means an affected unit that is also subject to Phase II of the acid
			 rain control requirements set forth in Title IV of the federal Clean Air Act (
			 42 USC
			 7651d, et seq.).
