Thursday, April 20, 2017

ADEQ is issuing an ozone High Pollution Advisory (HPA) for Maricopa County, effective Thurs., April 20, 2017, and Fri., April 20, 2017. These HPAs are due to ozone levels expected to accumulate enough to exceed the federal health standard for ozone.

People most affected by ozone include children, senior citizens, people who work or exercise outdoors and people with pre-existing respiratory disease. Ozone can irritate the respiratory system, aggravate asthma and reduce the immune system’s ability to fight off respiratory infections. Ozone-related health problems include shortness of breath, coughing, wheezing, headaches, nausea, and throat and lung irritation.

Employers and Travel Reduction Program Transportation Coordinators are advised to activate their HPA Plans immediately. ADEQ further recommends that the general public limit outdoor activity while the HPA is in effect, especially children and adults with respiratory problems.

ADEQ, MCAQD and Valley Metro encourage residents and employers to use the following tips and resources to help make the air healthier to breathe:
  • Drive as little as possible, carpool, use public transit or telecommute
  • Re-fuel your vehicle after dark
  • Avoid waiting in long drive-thru lines, for example, at coffee shops, fast-food restaurants or banks – park your car and go inside
  • Visit valleymetro.org and ShareTheRide.com to plan a transit trip or find a carpool or vanpool
  • Use low-VOC (Volatile Organic Compounds) or water-based paints, stains, finishes and paint strippers and delay big painting projects
  • Make sure containers of household cleaners, garage and yard chemicals and other solvents are sealed properly to prevent vapors from evaporating into the air

While the new, more stringent federal health standard for ozone triggers more frequent Health Watches and HPAs, the fact is that over the past two decades, Arizona has achieved significant improvements in our overall air quality and more specifically, lower ozone levels. Each and every one of us can make a difference in continuing to improve the quality of the air we breathe through simple actions that follow.
