    Second Public Notice

    The Pima County Department of Environmental Quality (PDEQ) proposes to revise the existing Air Quality Permit No. 1052 to Tucson Electric Power (TEP) Irvington a.k.a. H.Wilson Sundt Generating Station (IGS) located at 3950 E. Irvington Rd. This significant permit revision amends the Class I Prevention of Significant Deterioration (PSD) permit for IGS and pertaining only to Unit 3. Unit 3 is not equipped with any pollution control device for Nitrogen Oxides (NOx) emissions. More stringent enforceable operational restrictions on Unit 3, to reduce (NOx) emissions, are identified in Section VI of the permit and shall become effective one year after the U.S. Environmental Protection Agency (EPA) approves the Arizona Department of Environmental Quality’s (ADEQ) Regional Haze (NOx) Reasonable Progress determination for Unit 3 and adopts Section VI of this permit as part of the State Implementation Plan (SIP) for Arizona.

    PDEQ is also proposing revisions to the Pima County portion of the Arizona SIP. PDEQ proposes the submittal of Section VI of the proposed revised permit to U.S. EPA for approval as a source-specific revision to the Pima County portion of the Arizona SIP. The PDEQ SIP revision will be included in ADEQ’s proposed comprehensive regional haze SIP revision and will support the enforceability of ADEQ’s long-term strategy pursuant to 40 CFR 51.308(f)(2) of the federal regional haze program. The program requires States to submit a long-term strategy for addressing regional haze visibility impairment in mandatory Federal Class I areas. These Federal Class I areas are granted special air quality protections under Clean Air Act section 162(a). ADEQ will provide for public notice and comment on the proposed Arizona comprehensive regional haze SIP separately.
