Part 217 - NITROGEN OXIDES EMISSIONS
Subpart U - NO[x] CONTROL AND TRADING PROGRAM FOR SPECIFIED NO[x] GENERATING UNITS
Section 217.472 - Low-Emitter Requirements
Current through Register Vol. 48, No. 38, September 20, 2024
Starting with the effective date of the permit referred to in Section 217.454(c), the budget unit electing low-emitter status shall be subject only to the requirements of this Section.
a) For each control period the owner or operator elects low-emitter status, the federally enforceable permit conditions must:
b) The Agency will notify the USEPA in writing of each unit electing low-emitter status pursuant to the requirements of subsection (a) of this Section and when any of the following occurs:
c) The unit shall become subject to the requirements of this Subpart if, for any control period under this Section, the fuel use restriction or the operating hours restriction under subsection (a) of this Section is removed from the unit's permit or otherwise is no longer applicable, or the unit does not comply with the fuel use restriction or the operating hours restriction under subsection (a) of this Section. Such unit shall be treated as commencing operation on September 30 of the control period for which the fuel use restriction or the operating hours restriction is no longer applicable or during which the unit does not comply with the fuel use restriction or the operating hours restriction.
d) The owner or operator of a unit to which the Agency has ever allocated allowances under Appendix E of this Part may elect low-emitter status. In that case, the Agency will reduce the Subpart U NOx budget by the number of allowances equal to the amount of NOx emissions the unit is permitted to emit during the control period, pursuant to a federally enforceable condition in the unit's permit. The owner or operator of a unit electing low-emitter status may demonstrate that it holds sufficient allowances to cover the unit's NOx emissions by offsetting the emissions from such unit, not to exceed its permitted emission limit as included in its federally enforceable permit, with allowances issued for voluntary NOx reductions meeting the requirements of Subpart X of this Part. The Agency will not reduce the Subpart U NOx budget by the allowances issued for NOx reductions obtained in accordance with Subpart X of this Part.
