Approval and Promulgation of Air Quality Implementation Plans; Utah; Foreword and Definitions, Revision to Definition for Sole Source of Heat and Emissions Standards, Nonsubstantive Changes; General Requirements, Open Burning and Nonsubstantive Changes; and Foreword and Definitions, Addition of Definition for PMINF10/INF Nonattainment Area

EPA is taking direct final action approving State Implementation Plan (SIP) revisions submitted by the Governor of the State of Utah. On July 11, 1994, the Governor submitted a SIP revision for the purpose of establishing a modification to the definition for ``Sole Source of Heat'' in UACR R307-1-1; this revision also made a change to UACR R307-1-4, ``Emissions Standards.'' On February 6, 1996, a SIP revision to UACR R307-1-2 was submitted by the Governor of Utah which contains changes to Utah's open burning rules, requiring that the local county fire marshal has to establish a 30-day open burning window in order for open burning to be allowed in areas outside of nonattainment areas. Other minor changes are made in this revision to UACR R307-1-2.4, ``General Burning'' and R307-1-2.5, ``Confidentiality of Information.'' In addition, on July 9, 1998, SIP revisions were submitted that would add a definition for ``PM<INF>10</INF> Nonattainment Area'' to UACR R307-1-1. This action is being taken under section 110 of the Clean Air Act.
