Ozone pollution continues to be a problem along the Lake Michigan shoreline, with rising temperatures and “drift” from states to the south of the border playing a large role. The American Lung Association’s 2018 “State of the Air” report found that while year-round particle pollution (PM) levels are greatly improving nationwide, ozone levels worsened in some counties, much of which was due to warmer temperatures in 2016, the second warmest year on record in the U.S.  As a result, the federal Environmental Protection Agency (EPA), has informed the state that parts of Milwaukee, Ozaukee, Racine, Washington, Waukesha, Kenosha, Door, Manitowoc and Sheboygan counties will be designated “non-attainment” under the latest standard of 70ppb.  However, all Wisconsin counties are expected to be classified at the lowest possible level – marginal – meaning that they will likely meet the standard by the 2020 deadline with measures already in place.

The Lung Association’s report issued the following grades:

 County  Ozone Grade  Short-Term PM  Yearly PM
 Dodge  D  B  Pass
 Jefferson  D  Did Not Collect (DNC)  DNC
 Kenosha  F  B  Pass
 Milwaukee  F  A  Pass
 Ozaukee  F  A  Pass
 Racine  INC  DNC  DNC
 Sheboygan  F  DNC  DNC
 Walworth  F  DNC  DNC
 Waukesha  C  A  Pass

Of those counties, Kenosha reported the highest number of ozone violations with 10.3 days.

Each year the “State of the Air” provides a report card on the two most widespread outdoor air pollutants, ozone pollution and PM. The report analyzes particle pollution in two ways: through average annual particle pollution levels and short-term spikes. Both ozone and particle pollution are dangerous to public health and can increase the risk of premature death and other serious health effects such as lung cancer, asthma attacks, cardiovascular damage, and developmental and reproductive harm.

Ozone Pollution
Warmer temperatures brought by climate change make ozone more likely to form and harder to clean up. Over the past decades, ozone pollution has decreased nationwide because the nation has cleaned up major sources of the emissions that create ozone, especially coal-fired power plants and vehicles. However, rising temperatures threaten those gains.

Several counties along Lake Michigan continue to be plagued with ozone that originates south of the state line, but is transported upwind. In recent state action, the Wisconsin legislature passed Wisconsin Act 159 that prohibits the use of the Sheboygan Kohler-Andrea State Park air quality monitor, which consistently records high levels of ozone, in the state monitoring network plan.

“While Sheboygan County is understandably frustrated with ozone that is often not of their making, removing the monitor is not the solution,” said Dona Wininsky, spokesperson for the Lung Association in Wisconsin.  “It is vitally important to maintain that monitor, as it is the only source of air pollution information for residents who live and work nearby. Removing the monitor doesn’t remove the problem – it only ignores it, which isn’t good for anyone’s health. Additionally, the monitor is the only tool Wisconsin has to document how ozone from the south is impacting Sheboygan County.”

In Racine County, state officials at the Wisconsin Department of Natural Resources (DNR) are predicting that emissions from the planned Foxconn development also will increase ozone pollution.  The DNR report stated that there will be an approximate four percent increase in volatile organic compounds (VOCs) and nitrogen oxides (NOx), both of which contribute to the formation of ozone.

Particle Pollution (PM)
Nationwide, the best progress in this year’s report came in reducing year-round levels of PM. Nine Upper Midwest cities, including Milwaukee improved their year-round particle levels to their lowest ever. PM is made of tiny particles that come from coal-fired power plants, diesel emissions, wildfires and wood-burning devices. These particles are so small that they can lodge deep in the lungs and trigger asthma attacks, heart attacks and strokes, and can even be lethal.

The report also tracks short-term “spikes” in PM. Many of these spikes can be directly linked to weather patterns like drought or to events like wildfires which are likely to increase because of climate change.

The Lung Association in Wisconsin calls on our members of Congress to defend the Clean Air Act, currently under threat from those who want to weaken this effective public health law. We also call on the U.S. Environmental Protection Agency to implement and enforce the law instead of trying to roll back major safeguards like the Clean Power Plan and cleaner cars, both steps that help us fight climate change and reduce air pollution.

While the report examined data from 2014-2016, this 19th annual report provides online information on air pollution trends back to the first report covering 1996-1998. Learn more at Lung.org/sota.
