This is a message from Allegheny Alerts. ACHD has preliminary information that all three ozone monitors in the county (Harrison, Lawrenceville and South Fayette) had an exceedance of the 8-hour NAAQS (National Ambient Air Quality Standards) on Monday, July 6. The 8-hour standard is .70 parts per million. Harrison registered .74 and both Lawrenceville and South Fayette registered .71. This is the first exceedance at a county ozone monitor since 7/10/2018. There were no such exceedances in 2019. Ozone is overwhelmingly weather dependent, and exceedances are likely during periods of high temperatures and no precipitation, which we’ve had across the region over the past week. Given the current forecast there may be additional ozone exceedances this week. Higher concentrations of ozone may cause breathing problems for the elderly, children, pregnant women and people with heart or respiratory disease. We encourage residents to view our Air Quality Dashboard ( http://bit.ly/2LJ6xv9) for the latest ozone levels and remind the public to protect themselves and to help reduce air pollution by voluntarily limiting pollution-producing activities such as: • Limit daytime driving. Combine trips when possible. • Don’t refuel. If you must, do so after 7 p.m. • Postpone mowing the lawn until after 7 p.m. • Save energy. Wash dishes and clothes with full loads. • Keep window shades/blinds closed during the day to cut down on air conditioning.
