## Abstract

The Environmental Protection Agency (EPA) is partially approving and partially disapproving State Implementation Plan (SIP) revisions submitted by the State of Utah on September 20, 1999. The September 20, 1999 submittal revised the numbering and format of the Utah Administrative Code (UAC) rules within Utah's SIP. In this action, EPA is acting on those rules from the September 20, 1999 submittal that still require EPA action. Specifically, EPA is approving R307-110-16, "Section IX, Control Measures for Area and Point Sources, Part G, Fluoride," and disapproving R307-110-29, "Section XXI, Diesel Inspection and Maintenance Program." In conjunction with our disapproval of R307-110-29, we are also disapproving the Utah Diesel Inspection and Maintenance Program, which Utah submitted as a revision to the SIP on February 6, 1996, and which was incorporated by reference in R307-110-29 as part of the September 20, 1999 submittal. This action is being taken under section 110 of the Clean Air Act (CAA).
