  • TEP Application for PSD Authorization

    TEP Irvington

    Tucson Electric Power Company (TEP) operates its Irvington Generating Station (IGS) under Class I Air Quality Operating Permit No. 1052 issued by the Pima County Department of Environmental Quality (PDEQ). IGS consists mainly of four steam boiler generating units, specifically, Unit 1, Unit 2, Unit 3 and Unit 4. TEP is proposing to modernize the station by replacing two 1950's era steam units (i.e., Units 1 and 2) with ten high-efficiency, fast-responding, state-of-the-art reciprocating internal combustion engines (RICE), each having a generating capacity of nearly 19 MW.  The RICE project expects to trigger a major modification for CO, PM2.5/PM10 and VOCs subject to the Prevention of Significant Deterioration (PSD) permitting. As such, air quality dispersion modeling analysis is required to demonstrate that new emissions from the major modification, will not cause or contribute to a violation of any National Ambient Air Quality Standards (NAAQS).
