## Abstract

In this final action, EPA is approving the request by the Forest County Potawatomi Community's (FCP Community) Tribal Council to redesignate certain portions of the FCP Community Reservation as a non- Federal Class I area under the Clean Air Act (Act or CAA) program for the Prevention of Significant Deterioration (PSD) of air quality. These regulations are designed to preserve the air quality in national parks and other areas that are meeting the National Ambient Air Quality Standards (NAAQS). The Class I designation will result in lowering the allowable increases in ambient concentrations of particulate matter, sulfur dioxide, and nitrogen dioxide on the Reservation.
