Summary

The United States Environmental Protection Agency, Region 9 (EPA) is issuing its final decision to grant approval, in accordance with the Clean Air Act, of the operating permit renewal for the South Point Energy Center, a 500 megawatt power plant located in Mohave County, Arizona, on the Fort Mojave Indian Reservation.

This facility is required to renew its Clean Air Act Title V Operating Permit in accordance with 40 CFR Part 71. The permit contains all of the Clean Air Act requirements that apply to the source and requires that the source conduct monitoring sufficient to enable the EPA and the public to determine whether the source is complying with the applicable air quality requirements. This proceeding is subject to the administrative requirements of 40 CFR 71.11.

A request for public comment regarding EPA's proposed title V permit renewal was published on August 2, 2018. We provided a 30-day public comment period, and we received only one comment from Calpine Corporation requesting to update the name of the responsible official. After consideration of the pertinent federal statutes and regulations, the EPA hereby issues a renewed title V permit to operate the South Point Energy Center.

A copy of the final permit prepared from the EPA, the statement of basis, the application, and all supporting materials submitted by the source are available for review by the public at the following locations:
