The 2022 AQMP presents a combined state and local strategy for attaining the 2015 federal 8-hour ambient air quality standard for ozone, the only federal clean air standard Ventura County does not meet, by the statutory compliance deadline of August 3, 2027. It was prepared to satisfy federal Clean Air Act planning requirements for areas designated as serious federal 8-hour ozone nonattainment areas, including, but not limited to, updated air quality information, an updated emissions inventory, local and state air pollutant control measures, new emission forecasts and projections, a new federal conformity budget for transportation projects, a reasonable further progress demonstration for precursors of ozone (reactive organic gases and nitrogen oxides), a new countywide emission carrying capacity, and a demonstration that Ventura County will attain the federal 8-hour ozone standard.
Photochemical air quality modeling indicates that Ventura County will attain the 2015 federal 8-hour ozone standard by 2026 using local, state, and federal clean air programs. The previous Ventura County AQMP, prepared in 2016, projected attainment of the 2008 federal 8-hour ozone standard by 2020. The United States Environmental Protection Agency (EPA) published a notice of proposed rulemaking on July 14, 2022, determining that Ventura County has attained that standard by its July 20, 2021 attainment date.
