The Environmental Protection Agency EPA is taking final action to partially approve and partially disapprove the state implementation plan SIP revisions submitted by the State of California pursuant to the requirements of the Clean Air Act CAA
or Act for the implementation, maintenance, and enforcement of the 2015 national ambient air quality standards NAAQS or standards for ozone. Specifically, the EPA is approving the SIP revision for all elements except those that relate to prevention of significant deterioration PSD. EPA is partially approving and partially disapproving three elements of the SIP revision due to PSD deficiencies in certain air pollution control or air quality management districts APCD, AQMD, or district. The disapprovals will not create any new consequences for these districts or the EPA as the districts are already subject to the EPAs federal PSD program at 40 CFR 52.21.
As part of this action, we are also reclassifying certain regions of the State for emergency episode planning purposes with respect to ozone. We are also approving into the SIP two updated state provisions addressing CAA
conflict of interest requirements for the entire state, and emergency episode plans for the Amador County APCD,
