Background and Purpose
On January 5, 2023, the U.S. Environmental Protection Agency (EPA) reclassifi­ed the Las Vegas Valley as a moderate nonattainment area for the 2015 ozone National Ambient Air Quality Standard. These regulations, adopted to satisfy EPA planning requirements for moderate nonattainment areas, address the Reasonably Achievable Control Technology (RACT) requirements in EPA’s control technology guidelines (CTG) for reducing VOC emissions associated with the production of ground-level ozone (smog). They establish emissions standards, compliance obligations, work practices, emissions control systems, registration, notification, recordkeeping, and reporting requirements, and new permitting or registration requirements for applicable owners or operations (“sources”).
