The Environmental Protection Agency (EPA) is proposing to determine that the San Joaquin Valley nonattainment area has attained the 1-hour ozone National Ambient Air Quality Standard. This proposed determination is based on the most recent three-year period (2012-2014) of sufficient, quality-assured, and certified data. Preliminary data for 2015 are consistent with continued attainment of the standard in the San Joaquin Valley.
