Ozone Forecast Restrictions for
Sources With Schedule Modifications
Section 22a-174-22(i) of the Regulations of Connecticut State Agencies (RCSA) provides an alternate form of compliance for sources that can prove that it is not technologically or economically feasible to comply with NOx emission limits:
(1) If the owner or operator of a stationary source subject to this section proves to the satisfaction of the Commissioner that it is not technologically or economically feasible for such source to comply with the emission limitations in subsections (e) through (g) of this section, except the emission limitation in subsection (e)(3) of this section, the Commissioner may by permit require NOx emission reductions through modifications of the schedule of NOx-emitting activities and implementation of other measures to reduce NOx emissions at such source. Such permit may include restrictions on operations on any day for which the Commissioner has forecast that ozone levels will be "moderate to unhealthly for sensitive groups," "unhealthly," or "very unhealthly."
(2) This subsection shall only apply to the following:
(A) Oil-fired turbine engines or fast-response double-furnace Naval boilers that generate power to create simulated high-altitude atmospheres for the testing of aircraft engines;
(B) Testing of fuel-burning equipment undergoing research and development; or
(C) Compression-ignition reciprocating engines used exclusively for the training personnel in the operation and maintenance of such engines aboard submarines.

A small number of sources operate under a Section 22a-174-22(i) schedule modification. Please contact CTDEEP at 860-424-4152 to obtain a list of affected sources and the specific order language for these facilities.
