Know Your Ozone Action Days
Ozone Action Days are usually called on hot, muggy days with little wind, when the amount of ground-level ozone is predicted to approach unhealthful levels and the federal standard for ozone could be exceeded.
What steps should you take on Ozone Action days to help improve the air quality? Mow your lawn only when necessary and late in the evening or early in the morning. Avoid using outboard motors, off-road vehicles, or other gasoline powered recreational vehicles. If you are barbecuing, use an electric starter instead of charcoal lighter fluid.
