## Abstract

The Environmental Protection Agency (EPA) is taking final action to partially approve and partially disapprove State Implementation Plan (SIP) revisions submitted by the State of Utah on September 15, 2006. The September 15, 2006 revisions contain new, amended and renumbered rules in Utah Administrative Code (UAC) Title R- 307 that pertain to the issuance of Utah air quality permits. The September 15, 2006 revisions supersede and entirely replace an October 9, 1998 submittal that initially revised provisions in Utah's air quality permit program, and partially supersede and replace a September 20, 1999 submittal. In this action, we are fully approving the SIP revisions in the September 15, 2006 submittal with the following exceptions: we are disapproving the State's rules R307-401-7 (Public Notice), R307-401-9(b) and portions of (9)(c) (Small Source Exemption), R307-401-12 (Reduction in Air Contaminants), and R307-410-5 (Documentation of Ambient Air Impacts for Hazardous Air Pollutants); we are limitedly approving and limitedly disapproving R307-410-6 (Stack Heights and Dispersion Techniques); and we are not acting on R307-101- 2, R307-401-14, R307-401-15, and R307-401-16 for the reasons explained in this action. This action is being taken under section 110 of the Clean Air Act (CAA).
