SEMCOG Regional Update

Today and tomorrow – July 21 and 22 – are Ozone Action days
SEMCOG members: Please inform your residentsSEMCOG announces that today and tomorrow are the first Ozone Action days of the year. This is the 21st year of the voluntary program that helps keep Southeast Michigan’s air clean. There were three Ozone Action days in 2013; there were 20 in 2012.Summer-like conditions are returning to Southeast Michigan for the next few days. That means plenty of sunshine, warm temperatures, and increased humidity. Weak winds will come from the south/southwest on Sunday into Monday. Moisture moving in allows humidity levels to rise.

With mostly sunny skies, ozone levels will rise. Those favorable conditions will continue into Monday. Temperatures at both the surface and upper levels continue to increase, making an upsurge in ozone likely in Southeast Michigan.

Here are some simple things that Southeast Michigan residents can do to help keep the air clean on the region’s first Ozone Action day of the season:

  • Try not to refuel on Ozone Action days. If you can, refuel the night before. If you need to refuel on an Ozone Action day, fill up in the evening when the weather is cooler and don’t “top off” the tank. If you have a newer vehicle with a capless gas cap, that will lessen the chances of gas fumes releasing into the air.
  • Reduce automobile use on Ozone Action days. Plan to carpool, use public transit, walk, or work at home. Delay or combine errands.
  • Save the outdoor chores for another day. Choose the lawn chair over the lawn mower.

Additional information on Ozone Action days is available on SEMCOG’s website at www.semcog.org; look for Ozone Action under “Hot Topics” on the home page. Those interested can also follow us on , , or LinkedIn. In addition to our traditional e-mail notifications, we will use these pages to keep Southeast Michigan residents up-to-speed on a variety of topics related to air quality.

Residents wishing to be added to SEMCOG’s Ozone Action e-mail notification list should send an e-mail to ozoneaction@semcog.org; put “notification” in the subject line and include name, phone number, and e-mail in the body of the e-mail.

Thanks to a regionally coordinated effort, Southeast Michigan’s air quality has steadily improved over the past two decades. That is due, in part, to the actions that residents take on Ozone Action days – and that gives credence to one of SEMCOG’s key messages – that a single action by many can make a difference. View the positive trends in effect for ozone, carbon monoxide, and fine particulate matter.
