BACKGROUND:
On October 1, 2015, the U.S. Environmental Protection Agency (EPA) revised the 8-hour ozone National Ambient Air Quality Standard (NAAQS), lowering both the primary and secondary standards from 0.075 to 0.070 parts per million. The Las Vegas Valley (Hydrographic Area 212) was designated as a marginal nonattainment area for the 2015 ozone standard, effective August 3, 2018. On January 5, 2023, EPA determined that the area failed to attain the 2015 ozone NAAQS by the applicable marginal nonattainment date and reclassified the Las Vegas Valley as a moderate nonattainment area. The reclassification notice established a submission deadline of January 1, 2023, for the area’s moderate attainment plan. On October 18, 2023, EPA issued a finding of failure to submit a moderate attainment plan for the Las Vegas Valley nonattainment area by the submission deadline.
Under Sections 172 and 182(b) of the Clean Air Act, Clark County is required to submit a state implementation plan (SIP) that meets the following planning requirements for moderate nonattainment areas: emission inventories, attainment demonstration, nonattainment new source review, 15% rate of progress, reasonably available control measures, reasonably available control technology, motor vehicle inspection and maintenance, contingency measures, and a motor vehicle emissions budget for transportation conformity. The attached plan is intended to satisfy EPA's requirements for moderate nonattainment areas and resolve its finding of failure to submit. The plan and all attachments may be reviewed at the following link: https://publicinput.com/e58566.
The plan was made available for public comment from August 15 through September 16, 2024, on the Department of Environment and Sustainability, Division of Air Quality's website. One comment was received. Attachment K documents the public review process. Information not yet included in Attachment K will be added after the public hearing and upon Board approval of this plan.
Staff requests the Board approve and adopt this plan and authorize staff to submit it to the State of Nevada and EPA for approval as a revision to the Nevada SIP.
