4. Air Quality Division Update on the NAAQS and the SIP for Texas KS and BF May 5, 2015 Page 4 National Ambient Air Quality Standards Required by the Federal Clean Air Act The United States Environmental Protection Agency (EPA) sets these health- based standards for clean air, called National Ambient Air Quality Standards (NAAQS), for six criteria air pollutants: –Ground-Level Ozone (O 3 ); –Particulate Matter (PM); –Nitrogen Dioxide (NO 2 ); –Sulfur Dioxide (SO 2 ); –Carbon Monoxide (CO); and –Lead (Pb).

5. Air Quality Division Update on the NAAQS and the SIP for Texas KS and BF May 5, 2015 Page 5 National Ambient Air Quality Standards The EPA is required to review the NAAQS every five years. For more information on the review process, go to the EPA’s NAAQS review Web page. (http://epa.gov/ttn/naaqs/review.html)EPA’s NAAQS review Web page States with areas failing to meet the NAAQS (nonattainment) are required to develop and submit to the EPA state implementation plan (SIP) revisions.

More information can be found at EPA’s NAAQS webpage (http://epa.gov/air/criteria.html)EPA’s NAAQS webpage * In 1997 EPA revoked the 1-hour ozone standard (0.12 ppm, not to be exceeded more than once per year) and in 2015 the EPA revoked the 1997 eight-hour ozone NAAQS (0.08 ppm); however, some areas have continued obligations under those standards (“anti-backsliding”).

20. Air Quality Division Update on the NAAQS and the SIP for Texas KS and BF May 5, 2015 Page 20 Proposed Revisions to the Ozone NAAQS On November 25, 2014, the EPA proposed to strengthen the primary and secondary NAAQS for eight-hour ozone. Primary NAAQS protect public health –Current NAAQS: 0.075 ppm –Proposed NAAQS: 0.065 ppm – 0.070 ppm –EPA will take comment on levels as low as 0.60 ppm and retaining the current standard of 0.075 ppm. Secondary NAAQS protect public welfare (trees, plants, ecosystems, etc.). –Current NAAQS: 0.075 ppm –Proposed NAAQS: 0.065 ppm – 0.070 ppm –Form is identical to the primary NAAQS but the target level will be based on the W126 index.

25. Air Quality Division Update on the NAAQS and the SIP for Texas KS and BF May 5, 2015 Page 25 Summary of the Proposed Revisions to the Ozone NAAQS In 2014: Ten Texas counties in three CSAs are above the current ozone NAAQS of 75 ppb. Eight additional Texas counties and four additional CSAs (18 counties and 7 CSA’s) would be above an ozone NAAQS set at 70 ppb. Ten additional Texas counties and five additional CSAs (28 counties and 12 CSA’s) would be above an ozone NAAQS set at 65 ppb. Six Texas counties in six CSAs have design values at or below 65 ppb. *It is expected that the secondary ozone NAAQS will be in a form identical to the primary ozone NAAQS.
