Limited Approval and Disapproval of Air Quality Implementation Plans; Nevada; Clark County; Stationary Source Permits

EPA is proposing a limited approval and limited disapproval of revisions to the Clark County portion of the applicable state implementation plan (SIP) for the State of Nevada. The submitted revisions include new and amended rules governing the issuance of permits for stationary sources, including review and permitting of major sources and major modifications under parts C and D of title I of the Clean Air Act (CAA). The intended effect of this proposed limited approval and limited disapproval action is to update the applicable SIP with current Clark County permitting rules and to set the stage for remedying certain deficiencies in these rules. If finalized as proposed, this limited disapproval action would trigger an obligation on EPA to promulgate a Federal Implementation Plan unless Nevada submits and we approve SIP revisions that correct the deficiencies within two years of the final action, and for certain deficiencies the limited disapproval would also trigger sanctions under section 179 of the CAA unless Nevada submits and we approve SIP revisions that correct the deficiencies within 18 months of final action.
