As a precautionary response to COVID-19, Ohio EPA is currently operating with most staff working remotely. If you are working with our staff on a current project and you know the name of the employee you are working with, email them at firstname.lastname@epa.ohio.gov or call them directly. The Agency website has contact information for every district, division, and office. In order to reach us, please contact Ohio EPA’s main phone line at (614) 644-3020 or the main line for the division or office you are trying to reach.

After March 23, our district offices and Central Office will be temporarily closed and will have increasingly limited ability to receive deliveries, plans, etc. All entities are encouraged to submit plans, permit applications, etc., electronically where there are existing avenues to do so, such as the eBusiness Center (eBiz). Please refer to the list of available services on the main eBiz webpage. We encourage you to make use of all that apply, even if you have not used eBiz in the past. Plans under 25 MB can be emailed. For large plans over 25 MB, entities should work with the reviewer/division to upload via LiquidFiles. Directions for submitting docs via LiquidFiles is available on YouTube. We apologize for the inconvenience and thank you in advance for your understanding. If you wish to send hard copies of documents to any of Ohio EPA’s district offices, the best method to ensure we receive these documents is to send them via U.S. Mail. Since all offices are closed, deliveries outside of U.S. Mail (FedEx, UPS) will likely be returned because the offices are closed and deliveries cannot be made.

To report a spill or environmental emergency, contact the spill hotline (800) 282-9378 or (614) 224-0946

How Smog Affects Health

The U.S. Environmental Protection Agency has found that tailpipe emissions from cars and trucks account for at least one-third of the air pollution in the United States. Exposure to the pollutants found in vehicle emissions have been shown to cause serious health problems. Although today's cars emit much less pollution than in the past, there are more cars on the road traveling more miles than ever before. Ohio E-Check is an important initiative aimed at improving the air we breathe. Modeling by Ohio EPA shows that emissions testing removes a minimum of 74 tons per day of volatile organic compounds (VOCs), carbon monoxide (CO) and nitrogen oxides (NOx).


Pollutants

Carbon Monoxide

Carbon monoxide is a colorless, odorless, poisonous gas emitted from the vehicle's exhaust as a result of an incorrect air and fuel mixture resulting in incomplete combustion. Carbon monoxide interferes with the blood's ability to carry oxygen to the brain, heart and other tissues. Unborn or newborn children and people with heart disease are in the greatest danger from this pollutant, but even healthy people can experience headaches, fatigue and reduced reflexes due to CO exposure.

Six Common Air Pollutants - Carbon Monoxide

Ozone

Ozone is the major component in what we know as smog at ground level. Ozone is not emitted directly into the air but is produced in the lower atmosphere as a result of chemical reactions between oxygen and oxides of nitrogen in the presence of sunlight, especially in warm weather. This reaction normally results in a constant cycle where ozone is created and immediately broken down back into oxygen and NOx. However, hydrocarbons and other VOCs exist in the air which prevent ozone from breaking down, therefore increasing ozone concentrations. In the body, ozone reacts with lung tissue, causing inflammation of the lungs. Ozone can cause harmful changes in breathing passages, decrease the lungs' working ability and cause coughing and chest pains. Even healthy people are found to be sensitive to ozone exposure.

Six Common Air Pollutants - Ozone

Nitrogen Oxide

Nitrogen oxides (NOx) are produced when fuel is burned at excessive temperatures. These compounds are essential to ozone formation and are a health problem themselves. The effect of NOx exposure on the respiratory system is similar to that of ozone and sulfur dioxide.

Hydrocarbons (Volatile Organic Compounds)

Hydrocarbon emissions result from fuel that does not burn completely in the engine. Hydrocarbons are a type of volatile organic compound (VOC). VOCs are chemicals containing hydrogen, carbon and possibly other elements that evaporate easily. Hydrocarbons and other VOCs contribute to the formation of ozone by increasing the amount of nitric dioxide in the air, which then combines with oxygen molecules to produce nitrogen and ozone. A number of exhaust hydrocarbons are also toxic, with the potential to cause cancer.

Particulate Matter

Particulate matter includes microscopic particles and tiny droplets of liquid. Because of their small size, these particles are not stopped in the nose and upper lungs by the body's natural defenses but go deep into the lungs, where they may become trapped and cause irritation. Exposure to particulate matter can cause wheezing and similar symptoms in people with asthma or sensitive airways. Particulate matter can serve as a vector for toxic air pollutants.
