Speak of the Devil

Speaking of unhealthy ozone pollution, yesterday marked the first day this year that monitors in the Denver metro area registered an exceedance of current health standards. The monitor in Fort Collins had a reading of 0.081 parts per million; the current standard is 0.080 parts per million. Here's an overview from the state:

Sat. 6/24: Max 8-hour = 0.081 ppm at Fort Collins-West
(For the Denver area, max 8-hour = 0.075 ppm at Rocky Flats-N)

This value at Fort Collins-West is the first time this season that we have gone over 0.080 ppm for an 8-hour average.
