§ 52.2350 Emission inventories.
(a) The Governor of the State of Utah submitted the 1990 base year emission inventory of ozone precursors, which are volatile organic compounds, nitrogen oxides, and carbon monoxide, for the Salt Lake and Davis Counties ozone nonattainment area on January 13, 1995, as a revision to the State Implementation Plan (SIP). This inventory addresses emissions from point, area, non-road, on-road mobile, and biogenic sources. This Governor's submittal was followed by the submittal of corrections to the inventory, on April 20, 1995, from Russell Roberts, Director, Division of Air Quality, Utah Department of Environmental Quality. The ozone maintenance plan for Salt Lake and Davis Counties that the Governor submitted on February 19, 1997, incorporates by reference the corrected 1990 base year ozone emission inventory as background material. The 1990 ozone base year emission inventory requirement of section 182(a)(1) of the Clean Air Act, as amended in 1990, has been satisfied for the Salt Lake and Davis Counties area.
