If you are interested in air quality for our Region, please visit the Killeen-Temple Metropolitan Planning Organization (KTMPO) air quality page at

The Killeen and Temple urbanized areas have experienced considerable growth during the past 10 years, and it is projected to continue. On average, 65,000 cars travel through the region daily on Interstate 35. The harmful emissions from these vehicles contribute to the region’s air quality concerns. The Central Texas Air Information and Research (CTAIR) program has been established to carry out studies and activities to help ensure that the CTCOG region does not fall into the non-attainment status regarding current air quality standards.


***Rider 7 funding for the FY2018/2019 biennium was vetoed by the governor on June 12, 2017. For an explanation, please visit***

OZONE:  Good Up High, Bad Nearby!

Our region’s air quality is measured by the presence of ground-level ozone. Currently, ozone levels are considered safe in the Killeen-Temple region. Since ground-level ozone is caused largely by human activities, we must all do our part to keep our air clean.
