(a) The EPA is conditionally approving the SIP revision titled “Revision to Motor Vehicle Emissions Budgets in Ozone Redesignation Request and Maintenance Plan: Clark County, Nevada (October 2018).” The conditional approval is based on a commitment from the Clark County Department of Air Quality (DAQ) in a letter dated June 14, 2019, and a commitment from the Nevada Division of Environmental Protection (NDEP) dated June 21, 2019, to submit certain revised motor vehicle emissions budgets as a SIP revision to the EPA within one year of the effective date of the final conditional approval. If the Clark County DAQ or NDEP fail to meet their commitments within one year of the effective date of the final conditional approval, the conditional approval is treated as a disapproval.

(b) [Reserved]
