The Arizona Department of Environmental Quality has issued an Ozone High Pollution Advisory for Saturday, May 20 and Sunday, May 21.
Due to unhealthy levels of ozone, Maricopa County Air Quality Department requests all Transportation Coordinators to email employees and activate your HPA plans. The department encourages the use of alternative modes of transportation, especially when pollution levels are expected to be on the rise.
Remind employees that they are encouraged to make more clean air. By taking small, simple steps every day, we can all make a difference. Additional tips on how to reduce air pollution can be found at www.CleanAirMakeMore.com.
Ozone: Ground level ozone is formed by a chemical reaction that needs heat from sunlight, nitrogen oxides and VOCs to form. The months of April through September make up our Valley’s longer-than-normal "ozone season."
"High Pollution Advisory" or "HPA" means the highest concentration of pollution may exceed the federal health standard. Active children, adults and people with lung disease such as asthma should reduce prolonged or heavy outdoor exertion. Maricopa County employers enlisted in the Travel Reduction Program are asked to activate their HPA plans on high pollution advisory days.
