Fort Collins is part of the ozone non-attainment area.
In November 2007, the U.S. EPA designated much of the entire Front Range region, including Fort Collins, as "non-attainment" for the federal health standard for ozone. Currently, Fort Collins remains part of this "non-attainment" region.
Frequently Asked Questions
- What is Ozone?
Ozone is a molecule of three oxygen atoms bound together (O3). It is unstable and highly reactive. "Good" ozone in the upper atmosphere protects us from harmful ultraviolet rays. However, the ozone that affects us negatively is ground-level air pollution that forms when emissions from cars, lawn & garden equipment or volatile substances (paints, solvents) bake in the sunshine. Ozone levels build up during the heat of the day under hot, sunny conditions with little to no wind.
- What is being done to bring the region into compliance?
The North Front Range Metropolitan Planning Organization is partnering with the Denver Regional Air Quality Council and the Colorado Department of Public Health and Environment to develop an ozone compliance plan, or SIP (State Implementation Plan).
- How does ozone affect human health?
The reactivity of ozone causes health problems because it damages lung tissue, reduces lung function, and increases the sensitivity of the lungs to other irritants. Symptoms of decreased lung function include chest pain, coughing, sneezing and pulmonary congestion. Ozone can also act as an irritant to the mucous membranes of the eyes and throat and can reduce immune system capacity. In high concentrations, ozone causes damage to plants and deteriorates materials such as rubber and nylon.
- Who is most at risk?
Scientific evidence suggests that ozone affects not only individuals with respiratory problems, but also affects healthy adults and children.
- What are ozone action alerts?
Ozone action alerts are issued by the Colorado Department of Public Health during the summer ozone season (June 1 - August 31) based on daily forecasts of conditions that produce higher ozone levels. Ozone messages on any alert will be tailored to the expected ozone level so that groups at particular risk can be advised. Individuals can obtain a daily air quality advisory on-line. The State also operates a toll-free telephone hotline to help keep Colorado residents informed about current and predicted air quality conditions. The number is 1-888-484-3247 (1-888-4-THE AIR).
- What happens if there is an ozone action alert day?
During ozone alert days, people can lower their risk of developing symptoms by limiting prolonged outdoor exposure. If ozone levels are moderately elevated, unusually sensitive individuals may experience symptoms and are encouraged to stay indoors as much as possible.
- What are ozone levels in Fort Collins?
- What can I do to help reduce ozone pollution?
During the summer season, and especially during ozone action alerts, everyone can do their part to reduce ozone pollution by taking voluntary and simple steps:
- Stop at the click when refueling
- Limit driving, combine trips or use alternative transportation
- Mow when the sun is low
- Use a spill-free gas can for fueling lawn and garden equipment
