Ozone Action Season

The 2015 Ozone Action Season has ended
The Ozone Action Season extends from May through September. The ozone forecasts will resume again in May 2016. Thank you to the City of Toledo Division of Environmental Services staff for distributing forecasts throughout the ozone season and
for conducting the Gas Cap Replacement Program. Both efforts help to protect residents sensitive to ozone and other airborne pollutants.

Ozone Forecast:  
Monday, September 14, 2015 - Good
Tuesday, September 15, 2015 – Good
Wednesday, September 16, 2015 – Good
Thursday, September 17, 2015 – Good

The levels of ozone (from best conditions to worst):
Precautionary Measures Should be Taken by Sensitive Groups

2015 Ozone Action Program
During the months of May through September, ozone forecasts will be made predicting one of four levels of air quality conditions: Good, Satisfactory, Precautionary Measures should be taken by Sensitive Groups, and Caution. Forecasted air quality levels will be made available a minimum of twice each week; more frequent updates may occur during periods of unusual weather conditions.
Please send an email to if you would like to be included on or removed from the ozone forecast email list.

Ground level ozone is a lung irritant and can be especially dangerous to those with respiratory conditions, children, the elderly, and those who do a lot of outdoor exercise.
To help reduce pollution levels, we encourage you to:

  • Carpool, use public transportation, bike or walk whenever possible
  • Refuel vehicles after dark
  • Conserve energy - at home, at work, everywhere
  • Use environmentally safe paints and cleaning products whenever possible

Ozone Action Season Best Management Practices to Reduce Ground-level Ozone Formation

10 Tips for the Public

- Drive less. Drive more slowly. Share a ride, chain trips, walk or bike. Take public transportation.

- Refuel your car or fill gas cans in the morning or after 6 p.m. Avoid spilling gas or releasing vapors.

- Conserve energy in your home to reduce energy needs: hang clothes outside to dry rather than operate a dryer, set your thermostat between 76-78 degrees in the summer to reduce air conditioner use.

- Properly maintain your vehicle. Get a tune up and inflate tires to the correct pressure.

- Turn your car off. Park the car and walk into the building instead of using the drive thru.

- Change your mowing habits. Mow the lawn less frequently or mow earlier in the morning or in the evening.

- Insulate and weather-strip your home.

- Run dishwasher and washing machines only when fully loaded.

- Turn off lights and appliances when not in use.

- Apply paint with rollers and brushes instead of sprays to cut down on fumes and to save paint.

6 Tips for Business and Industry - Implement an Ozone Action Season Plan.

- Encourage employees to share rides or carpool.

- Use conference calls to avoid travel.

- Coordinate voluntary efforts to reduce emissions through technological advances.

- Delay fleet fueling until late in the day.

- Publicize Ozone Action Season on government broadcast channels.

Ozone and Health
Ozone that is part of the Earth's upper atmosphere is helpful to us; it shields us from ultraviolet radiation. But ozone that accumulates at ground level is dangerous. Ozone at ground level damages lung tissue in people, and new research shows that it also damages growing plants and can affect agriculture. Breathing ozone can worsen bronchitis, emphysema, and asthma. "Bad" ozone (ground-level ozone) also can reduce lung function and inflame the linings of the lungs. Repeated exposure may permanently scar lung tissue. Healthy people also experience difficulty breathing when exposed to ozone pollution. Ozone can trigger a variety of health problems including chest pain, coughing, throat irritation, and congestion. Because ozone forms in hot weather, anyone who spends time outdoors in the summer may be affected, particularly children, outdoor workers and people exercising. Children are especially vulnerable because of their developing lungs. Millions of Americans live in areas where the national ozone health standards are exceeded. Ground-level ozone also damages vegetation and ecosystems. It leads to reduced agricultural crop and commercial forest yields, reduced growth and survivability of tree seedlings, and increased susceptibility to diseases, pests, and other stresses such as harsh weather. In the United States alone, ground-level ozone is responsible for an estimated $500 million in reduced crop production each year. Ground-level ozone also damages the foliage of trees and other plants, affecting the landscape of cities, national parks and forests, and recreation areas.

Why Individual Actions Matter
Half of the hydrocarbons that lead to ozone come from the actions of individuals - driving cars, maintaining a home, using chemicals like paint or lighter fluid. This means that individuals can have a significant effect on reducing ozone through conscious efforts.

Protect Your Health
People can reduce their exposure to ozone by changing the time of their activity or simply taking it easier on days when ozone levels are expected to be high. For example, a runner could run in the morning when ozone levels are lower, instead of in the afternoon when conditions tend to be more favorable for ozone formation. During the hottest time of the day, children and people with asthma or breathing problems should spend more time in air-conditioned areas.

Ground level ozone is a lung irritant and can be especially dangerous to those with respiratory conditions, children, the elderly, and those who do a lot of outdoor exercise.
