Supplementary Information

Section 169A of the Clean Air Act (CAA) establishes as a national goal the “prevention of any future, and the remedying of any existing, impairment of visibility in mandatory Class I Federal areas which impairment results from manmade air pollution.” Arizona has twelve mandatory Class I areas; several Class I areas in other states are also affected by emissions from Arizona facilities.

Regional haze is visibility impairment caused by the cumulative air pollutant emissions from numerous sources over a wide geographic area. EPA's proposed Regional Haze Federal Implementation Plan (FIP) for Arizona addresses the requirements of the CAA and EPA's regional haze regulations pertaining to Best Available Retrofit Technology (BART) for three electric generating stations in Arizona: Apache Generating Station, Cholla Power Plant and Coronado Generating Station. EPA will propose to address other facilities and other elements of the Arizona SIP in a later action. The proposed rule, “Approval, Disapproval and Promulgation of Air Quality Implementation Plans; Arizona; Regional Haze State and Federal Implementation Plans”, was published in theFederal Registeron July 20, 2012 (77 FR 42833).

The proposed rule and information on which the proposed rule relies are available in the docket for this action. Generally, documents in the docket for this action will be available electronically at and in hard copy at EPA Region IX, 75 Hawthorne Street, San Francisco, California. While all documents in the docket are listed at, some information may be publicly available only at the hard copy location (e.g., copyrighted material, large maps), and some may not be publicly available in either location (e.g., Confidential Business Information).

At the public hearings, the hearing officer may limit the time available for each commenter to address the proposal to five minutes or less if the hearing officer determines it is appropriate.
