This rule change updates the version of the Code of Federal Regulations (CFR) that is incorporated by reference throughout the Utah Air Quality rules. This rule does not cover rules that specify its own date for the version of the CFR they incorporate by reference, for example, Rules R307-210 and R307-214. There were no substantive changes to any specific portions of the CFR outside of the Code sections incorporated by Rules R307-210 and R307-214. A summary of every federal rule that is being incorporated by Section R307-101-3 can be found at http://www.deq.utah.gov/boards/airquality/docs/05May/May_4_2016_Packet.pdf (pgs. 56-57).
