Air Quality in Clermont County

Resize font A- A A+

The Southwest Ohio Air Quality Agency (SOAQA) is the regional agency that works with local, state and federal government agencies, businesses, communities and citizens to achieve and maintain healthy air quality for southwestern Ohio. SOAQA serves Clermont County, as well as Hamilton, Butler, and Warren counties. Some of the Division's many responsibilities include:

  • coordinating permitting of air emissions
  • conducting facility inspections
  • responding to complaints
  • providing open burning permits
  • monitoring of air pollutants, and
  • issuing smog alerts.

The complaint program focuses on outreach activities and operating the air quality hotline. The 24-hour hotline (513-946-7777 or 800-889-0474), established in 1991, provides prompt service to the air quality concerns of residents in the four-county area of Butler, Clermont, Hamilton, and Warren counties. The hotline enables residents to call a SOAQA staff member 24-hours a day, seven days a week (with the exception of major holidays) to report any outdoor air quality concerns. For more information, see filing a complaint.

SOAQA also monitors air pollutants daily at several sites in the region, including one site in Clermont County. Continuous ozone levels and particulate matter are monitored at a station near Batavia.  For more information visit SOAQA's Air Quality Monitoring Network

Twice a day, monitoring data at all stations are assembled into a regional Air Quality Index (AQI). The index is a scale that measures five major air pollutants - inhalable particulates, ozone, sulfur dioxide, carbon monoxide and nitrogen dioxide. SOAQA provides local media and the public with daily AQI values as an indication of that day's air quality.
