BACKGROUND:
On October 1, 2015, the U.S. Environmental Protection Agency (EPA) revised the 8-hour ozone National Ambient Air Quality Standards (NAAQS), lowering both the primary and secondary standards from 0.075 to 0.070 parts per million. When EPA establishes or revises an existing NAAQS, EPA must designate areas as meeting or not meeting the standard, and states are required to develop state implementation plans (SIP) that outline how it will attain or maintain the standard. The Las Vegas Valley was designated as a marginal nonattainment area for the 2015 ozone standard, effective August 3, 2018.
Under the Clean Air Act and final implementation rule for the 2015 standard, Clark County is required to meet certain SIP requirements for marginal nonattainment areas. The purpose of the attached SIP revision is to address the nonattainment new source review program requirements for the Las Vegas Valley nonattainment area under the 2015 ozone standard.
The proposed revision was made available for public comment from May 26, 2021, through June 25, 2021. A public hearing on July 20, 2021, will provide the public with an additional opportunity to provide comments prior to the Board of County Commissioners' consideration of the revision.
