Heading: Clark County's New Source Review Program Revisions

Text: 13 At the time of enactment of the 1990 Amendments, Clark County's new source review program consisted of rules that were last approved by the EPA in 1981. 46 Fed. Reg. 21,758 (Apr. 14, 1981). The revised new source review program at issue here was approved by the EPA on May 11, 1999. 64 Fed. Reg. 25,210 (May 11, 1999). 14 Parts of Clark County, including the Las Vegas Valley, have been in nonattainment for particulate matter and carbon monoxide from the time of the EPA's approval of the 1981 Rules to, as far as the record shows, the present. 4 The 1990 Amendments required Clark County to submit revisions to its new source review program by November 1992. Clark County missed this deadline. But, from 1993 until submission to the EPA in 1999, Clark County engaged in an involved process of revising its new source review program. During this period, Clark County received substantial input from the EPA, the regulated community, and the public.
