National Ambient Air Quality
Standards
• Required by the Federal Clean Air Act
• The United States Environmental
Protection Agency (EPA) sets these healthbased 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).

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.

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

Page 8
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)

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.

2. Take the 4th highest peak-hour ozone from
each year and find the average
69 + 73 + 72
= 71.334

3. Now truncate the average so there are no
decimal places and you have the design value
71.334 = 71 𝑝𝑝𝑏

Page 19
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.
