## Abstract

EPA is taking final action to correct an error in a previous rulemaking that revised the boundaries between nonattainment areas in Southern California designated under the Clean Air Act for the national ambient air quality standard for one-hour ozone. EPA is also taking final action to revise the boundaries of certain Southern California air quality planning areas to designate the Indian country of the Morongo Band of Mission Indians, California as a separate air quality planning area for the one-hour and 1997 eight-hour ozone standards.
