Several environmental groups have sued EPA over an alleged failure to meet a May 2011 deadline for determining whether California’s San Joaquin Valley has met a national one-hour ozone standard set in 1979. Med. Advocates for Healthy Air v. EPA, No. n/a (N.D. Cal. filed 7/18/11). The complaint accuses EPA of missing one deadline after another for determining the San Joaquin Valley’s compliance with the Clean Air Act and of failing to act on a petition seeking an official finding that the Valley’s plan to address ozone pollution had failed. It seeks a court order forcing EPA to determine whether the Valley attained the one-hour ozone standard and an award of attorney’s fees and costs.
