PUBLIC NOTICE | Significant Permit Revision No. 63088 to Air Quality Control Permit No. 52639 for Salt River Project- Coronado Generating Station

ADEQ proposes two actions through this public notice: a revision to the Arizona State Regional Haze State Implementation Plan (SIP) and Significant Permit Revision No. 63088 to Air Quality Control Permit No. 52639 for Salt River Project — Coronado Generating Station located 6 miles northeast of St. Johns off U.S. Highway 191 in St. Johns, Apache County, Arizona.  

Facility mailing address:
     Salt River Project  Coronado Generating Station
     P.O. Box 52025
     Phoenix, AZ 85072-2025

The significant revision to the permit is intended as a component of the SIP revision to assist in satisfying the Arizona Regional Haze Best Available Retrofit Technology (BART) requirements. The SIP and permit revisions will become effective following EPA’s approval and final action rescinding the current Federal Implementation Plan. This permit revision requires SRP to select the option of either installing Selective Catalyst Reduction system on Unit 1 or shut down Unit 1 by Dec. 31, 2029. Until the time SRP decides either of these options, the Permittee will be required to seasonally curtail the operation of Unit 1 by selecting one of four interim operational strategies. The facility is subject to the requirements of the Federal Clean Air Act, Code of Federal Regulations, Arizona Revised Statute 49-426, and the Arizona Administrative Code, Title 18, Chapter 2.
