Clean Data Determination for 1997 PM2.
The Environmental Protection Agency (EPA) is extending the existing public comment period for a proposal published in the Federal Register on December 9, 2014. In that action, pursuant to the Clean Air Act, EPA proposed to determine that the Los Angeles-South Coast Air Basin (South Coast) air quality planning area in California has attained the 1997 annual and 24-hour fine particle (PM2.5) National Ambient Air Quality Standards. This proposed determination is based upon complete (or otherwise validated), quality-assured, and certified ambient air monitoring data showing that the area has monitored attainment of the 1997 annual and 24-hour PM2.5 standards based on the 2011-2013 monitoring period. If the EPA finalizes this determination of attainment, the requirements for the area to submit certain State implementation plan revisions shall be suspended for so long as the area continues to attain the 1997 annual and 24-hour PM2.5 standards. One commentor requested an extension of the comment period for this proposed rulemaking. EPA is now extending the public comment period for fourteen days.

Approval of Tribal Implementation Plan and Designation of Air Quality Planning Area; Pechanga Band of Luiseño Mission Indians
The Environmental Protection Agency (EPA) is proposing to revise the boundaries of the Southern California air quality planning areas to designate the reservation of the Pechanga Band of Luise[ntilde]o Mission Indians of the Pechanga Reservation, California as a separate air quality planning area for the 1997 8-hour ozone National Ambient Air Quality Standard. The EPA is also proposing to approve the Tribe's tribal implementation plan for maintaining the 1997 ozone standard within the Pechanga Reservation through 2025 because it meets the Clean Air Act's and the EPA's requirements for maintenance plans. Lastly, based in part on the proposed approval of the maintenance plan, EPA is proposing to grant a request from the Tribe to redesignate the Pechanga Reservation ozone nonattainment area to attainment for the 1997 8-hour ozone standard because the area meets the statutory requirements for redesignation under the Clean Air Act.
