Even though we know that heat and certain emissions create higher levels of ground-level ozone, we can’t always predict when those days will be. So, we created Ozone Awareness Days to give you a chance to practice all those behaviors that can reduce the pollutant – even on days when an Ozone Alert isn’t issued.

June 10 – 13
July 15 – 18
August 12 – 15

Ride the Metro bus on these days to get 50-cent fares and 25-cent transfers (exact change, please) – plus reduce the emissions from your exhaust. It’s one of the major sources of NOx and VOCs that cause ground-level ozone.
