The Treasure Valley’s Inspection and Maintenance (I/M) p rograms were implemented to help reduce air pollutants. However, modeling results show I/M programs are not as effective as they once were due to vehicle turnover and new, stricter federal motor vehicle emissions standards. Additionally, air quality in the Treasure Valley has improved over the past three decades and the area is currently meeting all national health-based standards. In 2022, the Idaho Legislature passed a law to repeal the state requirement for vehicle I/M programs (e.g., emissions testing), effective July 1, 2023.
