ALT Since February 3, Allegheny County Health Department staff have been monitoring the train derailment situation and its aftermath in East Palestine, Ohio. To date, our monitors and analysts reviewing the county’s air quality data have not seen any air quality changes that can be attributed to the derailment. The county’s air quality monitors do detect several of the pollutants like benzene and vinyl chloride. With more than 25 miles from East Palestine to the county border, any emissions would likely disperse before reaching the county, but will still continue to be monitored. Additionally, the U.S. Environmental Protection Agency (EPA), Pennsylvania, Department of Environmental Protection (PA DEP) and Ohio Department of Environmental Protection (Ohio EPA) have been on the scene monitoring air quality since the train derailment. These agencies have not reported any levels of volatile organic compounds (VOCs), hazards air pollutants (HAPs) or criteria pollutants from the train derailme
