Polluted Air Welcomes Summerfest; Walker DNR Now Holds Back Information

If the Wisconsin DNR hadn't ended "air quality watches" under new Walker administration procedures about publicizing dirty air conditions as they build to unhazardous levels, people making plans to hoof it across the Summerfest grounds on opening night might have thought twice about it.

But the DNR, since this March 11, 2001 email, now issues an "air quality advisory" only after conditions are already at an unhealthy stage:

"Wisconsin Department of Natural Resources"

 

To:

As of March 15, 2011, the Wisconsin DNR will no longer issue Air Quality Watches for ozone and particle pollution due to limited staff resources and the potential increase in the number of air quality notices under proposed revisions to federal air standards.

In the past, an air quality watch was issued when conditions were favorable for pollutants to reach unhealthy levels.

So today, Bucky, you're advised that ozone, a component of smog from tailpipe and smokestack emissions, is at an unhealthy stage for seniors, children, people doing outdoor exercises, and others with lung problems, such as asthma:
