Four Corners Power Plant 

Announcement of Proposed Permit, Public Hearings, and Request for Public Comment on the 

Proposed Clean Air Act Prevention of Significant Deterioration Permit and Minor NSR Permit in 

Indian Country 

PSD Permit No. NN 14-01 

Tribal Minor NSR Permit: T-002-NN 

The United States Environmental Protection Agency, Region 9 (EPA) provides notice of, and requests public 

comment on, EPA’s proposed action relating to the Prevention of Significant Deterioration (PSD) permit 

application (Application) for the addition of selective catalytic reduction (SCR) systems at Four Corners Power 

Plant (FCPP). EPA is issuing a proposed PSD permit and Minor New Source Review (NSR) Permit in Indian Country 

that would grant conditional approval, in accordance with the PSD regulations (40 CFR 52.21) and the Minor NSR 

regulations for Indian Country (40 CFR 49.151-161), to Arizona Public Service Company (APS). The permit would 

authorize APS to construct and operate SCR systems, including ancillary equipment, on two existing coal-fired 

electric steam generating units at FCPP (hereinafter, the FCPP SCR Project). The address for APS is P.O. Box 35, 

Fruitland, NM 87416-0355. The proposed location for the FCPP SCR Project is at the existing FCPP located at the 

end of San Juan County Road 6675 in Fruitland, NM. 

The proposed permit for the FCPP SCR Project would require the use of Best Available Control Technology 

(BACT) to limit emissions of sulfuric acid mist (SAM), to the greatest extent feasible. Air pollution emissions from 

the Project would not cause or contribute to violations of any National Ambient Air Quality Standards (NAAQS). 

All written comments must be received or postmarked by September 24, 2014. Comments must be sent or 

delivered in writing to Lisa Beckham at one of the following addresses:

Comments should address the FCPP SCR Project and the proposed permit, including such matters as: 

1. The best available control technology (BACT) determination for sulfuric acid mist; 

2. The effects, if any, on Class I areas; and 

3. The effect of the proposed modification, if any, on ambient air quality. 

Before the Public Hearings described below, EPA will hold two Public Information Meetings for the purpose of 

providing interested parties with additional information and an opportunity for informal discussion of the
