Orange County Receives Federal Funding to Measure Outdoor Air Quality

Orange County’s Environmental Protection Division was recently awarded a federal grant to add an outdoor air quality monitoring station in order to measure air quality impacts from vehicle traffic. Due to population growth, the United States Environmental Protection Agency (EPA) is funding a fourth air quality monitoring station to be installed near an Orange County roadway to monitor peak nitrogen dioxide levels.  Nitrogen dioxide (NO2) is a typical pollutant emitted from gas-powered vehicles.

For this project, Orange County has already received $50,000 in federal grant funding from the EPA.  An additional $150,000 from the grant will cover the purchase of monitoring equipment and installation of a small protective building on the site. The grant does not require the County to use any matching funds.  The EPA and Orange County Environmental Protection Division’s goal is to have a new monitoring site location selected by mid-2020, and for it to become operational in 2021.

Air pollutants come from many sources such as vehicle exhaust, dust, and emissions from commercial activities.  Scientists and engineers at Orange County’s Environmental Protection Division routinely work with the USEPA and the Florida Department of Environmental Protection in efforts to continuously monitor air quality, enforce ordinances and implement programs designed to protect the health of County residents.

Air quality in Orange County typically falls within the Air Quality Index “good” range.  To check the current Air Quality Index, visit the Air Now website at  You can also subscribe to to have daily air quality forecasts sent to you via email and/or text message.  For more information, visit Orange County’s Air Quality Management webpage.
