Chapter 446c - Air Pollution Control
Section 22a-197. - Sulfur dioxide emission standards: Definitions.

For purposes of this section, section 22a-198 and subsection (a) of section 16-245l:

(1) “Affected unit” means any emissions unit subject to the provisions of the Post-2002 Nitrogen Oxides Budget Program, as described in the regulations adopted under section 22a-174.
(2) “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.
(3) “Calendar quarter” means the period of January first to March thirty-first, inclusive, April first to June thirtieth, inclusive, July first to September thirtieth, inclusive, or October first to December thirty-first, inclusive.
(4) “MMBtu” means million BTU of heat input.
(5) “Sulfur dioxide” or “SO2” means a gas that at standard conditions has the molecular form SO2.
(6) “Sulfur Dioxide Discrete Emission Reduction Credit” or “SO2 DERC” means the reduction of one ton of sulfur dioxide at a stationary source during the generation period, which the commissioner has certified in writing as real, quantifiable, surplus, permanent and enforceable. Early reduction credits shall qualify as SO2 DERCs.
(7) “Early reduction credit” means a reduction of SO2 during calendar years 1999, 2000, 2001 or 2002 below the most stringent SO2 emission rate applicable to an affected unit.
(8) “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 72, 73, to emit up to one ton of SO2 during or after a specified calendar year.
(9) “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.
