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 (O3);– Particulate Matter (PM);– Nitrogen Dioxide (NO2);
– Sulfur Dioxide (SO2);– Carbon Monoxide (CO); and– Lead (Pb).
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)
• States with areas failing to meet the NAAQS (nonattainment) are required to develop and submit to the EPA state implementation plan (SIP) revisions.

Current NAAQS
Note: Secondary NAAQS are the same as the primary NAAQS for all pollutants EXCEPT SO2, which has a
secondary NAAQS of 0.5 ppm over three hours, and PM2.5, which has a secondary NAAQS of 15.0 µg/m3 annually.
More information can be found at EPA’s NAAQS webpage (http://epa.gov/air/criteria.html)
* 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”).

Design Values
Air Quality Division • Update on the NAAQS and the SIP for Texas • KS and BF • May 5, 2015 • Page 9
Data Completeness
• Most design value calculations require a data completeness check
• Data completeness checks vary by NAAQS, but in general:– A design value must have at least 75% complete
data for the year– A design value that exceeds the NAAQS but has
incomplete data is still considered valid– Additional tests can be used to validate a design
value with incomplete data• See the Federal Register for an individual
criteria pollutant for more information (http://www.epa.gov/air/criteria.html)
Air Quality Division • Update on the NAAQS and the SIP for Texas • KS and BF • May 5, 2015 • Page 10
Calculating Eight-Hour Ozone Design Values
• Find the fourth highest eight-hour daily peak at each monitor
• Average those fourth highest values from the most recent three years; do this for each monitor. This is the design value for your monitor.
• The design value for a county or Metropolitan Statistical Area (MSA) is the maximum design value from all of the monitors located within that county or MSA.
Air Quality Division • Update on the NAAQS and the SIP for Texas • KS and BF • May 5, 2015 • Page 11
Calculating Eight-Hour Ozone Design Values: An Example
1. Monitor A has three years of complete data4th Highest Peak Eight-Hour Ozone for Monitor A was 95 in 2009, 88 in 2010 and 86 in
2011.
2. Take the 4th highest peak-hour ozone from each year and find the average
3. Now truncate the average so there are no decimal places and you have the design value
2011 2012 2013
Maximum Peak Eight-Hour Ozone 87 85 86
2nd Highest Peak Eight-Hour Ozone 85 83 80
3rd Highest Peak Eight Hour Ozone 70 78 75
4th Highest Peak Eight-Hour Ozone 69 73 72

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.

Comparing Design Values to the NAAQS
• Design values must be greater than the NAAQS for an area to exceed.
• If the NAAQS are set at 70 ppb (0.070 ppm):– 70.99999 ppb -> 70 ppb -> MEETS NAAQS– 71.00001 ppb -> 71 ppb -> EXCEEDS NAAQS
• If the NAAQS are set at 65 ppb (0.065 ppm):– 65.99999 ppb -> 65 ppb -> MEETS NAAQS– 66.00001 ppb -> 66 ppb -> EXCEEDS NAAQS

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.
