Air Quality Matters!

RAPCA measures air quality with an extensive network of air quality monitors. Monitor locations are determined using criteria set by U.S.EPA's Office of Air Quality Planning and Standards.

The data from these monitors is used to calculate the Air Quality Index (AQI).  The AQI uses a simple color coded system (Green, Yellow, Orange and Red) to report daily air quality and focuses on health effects you may experience within a few hours or days after breathing polluted air.  

RAPCA issues AQI forecasts each day so if you’re interested in receiving these forecasts, or want to learn more about the AQI, please visit U.S. EPA’s Enviroflash website.  RAPCA’s air quality data is also used to determine whether our air meets U.S. EPA's National Ambient Air Quality Standards (NAAQS).

If you’re interested in learning more about our area’s designation status, please visit Ohio EPA's Attainment Designations page.

Beginning in 2016, RAPCA and Waste Management began a canister sampling project near the Stony Hollow landfill in Dayton.  In May 2017, RAPCA expanded the sampling with a community monitoring project.

* RAPCA was granted permission from U.S. EPA to stop monitoring for lead at Site 8 at the end of 2016.  RAPCA began sampling at this location in late 2011 and since sampling began, lead levels have shown to be less than 10% of the National Ambient Air Quality Standard, therefore eligible for cessation.

Asbestos is the name given to a group of minerals that occur naturally in the environment as bundles of fibers that can be separated into thin, durable threads. These fibers are resistant to heat, fire, and chemicals and do not conduct electricity. For these reasons, asbestos has been used widely in many industries, including the building and construction industries for roofing, fireproofing, sound absorption and thermal system insulation.  Asbestos has also been used in other building materials such as ceiling and floor tiles, adhesives, leveling compounds, drywall joint compound, plaster, pipe insulation, and cement board siding and shingles.

People may be exposed to asbestos if asbestos containing products are disturbed and tiny asbestos fibers are released into the air. When asbestos fibers are breathed in, they may get trapped in the lungs and remain there for a long time. Over time, these fibers can accumulate and cause scarring and inflammation, which can affect breathing and lead to serious health problems, including cancer.

RAPCA enforces federal, state, and local asbestos regulations to protect the public from asbestos fibers that may become airborne if strict adherence to regulations is not followed when a building is being renovated or demolished.

Owners and/or contractors are required to comply with asbestos regulations. Before any type of renovation or demolition project is to begin, you must determine if it is subject to the asbestos regulations.
