Department Head:
Lynne A. LiddingtonThe primary responsibility of the Air Quality Management Division is to achieve and maintain the National Ambient Air Quality Standards in Knox County, for all criteria pollutants designed to protect health and welfare, as set by local and federal law.
This is accomplished through the following activities: the continuous monitoring of the ambient air to determine air quality levels; issuance of health alerts concerning air quality; permitting of industrial air contaminant sources; review of industrial source testing, computer modeling of air pollution dispersion; and air toxics evaluation and control. The department also performs compliance and complaint investigations, issues residential open burning permits and provides technical and educational services.
The smoke from a fire may not bother you but it could be a real problem and a serious health threat for your neighbors. Violations can result in substantial penalties. If you have any questions, or would like to report a suspected open burning incident, contact your Knox County Air Quality Office. Click here for more information on Open burning in Knox County.
Knox county air quality updateFor Knox County's air quality, there's good news and bad news. The good news is that all the air isn't unhealthy. In fact, today most areas are in the Green or good range. However, the air within the areas impacted by smoke from the mulch fire near downtown is unhealthy. And the affected area changes with weather and wind patterns that move the smoke through the air. This is important because where there is smoke, the air quality is unhealthy. If the air where you are looks smoky or if you can smell smoke, the air quality is poor. In the affected areas, Knox County Health Department officials recommend that everyone should avoid prolonged or heavy exertion outside. In smoky areas, the public is advised to stay inside with the air conditioning on and set to recirculate inside air, if the unit permits.
