2018 ‘State of the Air’ report for Delaware: Philadelphia metro area posts passing grades for fine particle pollution, but New Castle County worsens and fails for ozone

Kent, Sussex Counties cleanest for short-term particle pollution, continue passing grades for ozone smog, according to American Lung Association’s 19th annual air quality report

The American Lung Association’s 2018 “State of the Air” report found that ozone air pollution in Delaware and throughout much of the Mid-Atlantic worsened when compared with last year’s report, even as fine particle pollution levels continued their steady improvement.  The “State of the Air” report gives results for three measures of air pollution—days with elevated ozone, and daily and annual values for fine particle pollution.

The Philadelphia-Reading-Camden, PA-NJ-DE-MD metro area, which includes both New Castle and Kent Counties, again met the national standard for year-round particle pollution, according to the 19th annual “State of the Air report.  The metro area ranked 12th worst of 187 across the country in the current report, despite posting its best-ever results for the sixth consecutive year.

For the daily measure of fine particle pollution, Sussex County’s seventh straight “A” grade again placed the Salisbury, MD-DE metro area on the Cleanest U.S. Cities list for this measure.  Kent County also posted its seventh year with an “A” grade.  Not only did New Castle County show improvement, but for the first time, the Philadelphia metro area earned passing grades for all counties posting results.  The metro area’s rank also improved, from 20th worst last year to 31st worst of 201 metro areas in the current report.

For ozone, Delaware’s two metro areas told different stories:  With the sole exception of Atlantic County, NJ all monitored counties in the Philadelphia metro area, including Kent and New Castle Counties, posted worse results than in last year’s report.  As many other areas also had problems with ozone increases, the metro area’s rank nevertheless improved a bit from 22nd worst last year to 24th worst of 227 in the current report.  In contrast, with Sussex County recording its fourth consecutive best ozone result, its Salisbury, MD-DE metro area’s rank improved from 63rd to 72nd worst.

Compared to the 2017 report, the Philadelphia-Reading-Camden metro area has seen a distinct increase in unhealthy days for ozone and a continuing gradual improvement in both measures of particle pollution.  This is in keeping with trends seen across the nation for both higher ozone and lower particle pollution levels than in last year’s report. In the case of year-round particle pollution, the Philadelphia metro area posted its 14th consecutive improvement in its worst county’s level since the 2004 report, and the Salisbury metro area, its tenth since the 2008 report.

“The 2018 ‘State of the Air’ report finds that unhealthful levels of ozone in Delaware put our citizens at risk for premature death and other serious health effects such as asthma attacks and greater difficulty breathing for those living with a lung disease such as COPD. As long as there are many days with high ozone levels, people with lung diseases such as asthma will continue to need medical attention,” said Kevin Stewart, Director of Environmental Health, American Lung Association of the Mid-Atlantic. “Across the nation, the report found continued improvement in air quality, but still, more than four in 10 Americans – 133.9 million – live in counties that have unhealthful levels of either ozone or particle pollution, where their health is at risk.”

The trends in this year’s report, which covers data collected by states, cities, counties, tribes and federal agencies in 2014-2016, confirm the ongoing challenges to reduce each pollutant in the changing political and outdoor climate.

“We can and should do more to save lives,” Stewart said. “The American Lung Association in Delaware 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 such as the Clean Power Plan and cleaner cars, both steps that help us fight climate change and reduce air pollution.” 

“This year’s ‘State of the Air’ report once again shows that when critical protections under the Clean Air Act are implemented, they work, helping us make progress in reducing various air pollutants that increase asthma attacks, lung disease and premature death,” said Senator Tom Carper (D-Del.), top Democrat on the Senate Environment and Public Works Committee. “But human caused climate change is working against these efforts, increasing rates of high heat and bad ozone days. Instead of addressing climate change and finding ways to further protect communities from air pollution, President Trump and EPA Administrator Scott Pruitt are doing just the opposite. This year’s report makes it clear – moving backward on clean air efforts isn’t a boon for our economy, it is an assault on the health of our families and our communities.”

For 19 years, “State of the Air” has provided a report card on the two most widespread outdoor air pollutants, ozone pollution, also known as smog, and particle pollution, also called soot. The report analyzes particle pollution in two ways: through average annual particle pollution levels and short-term spikes in particle pollution. 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 in Delaware
Compared to the 2017 report, both Kent and New Castle Counties experienced more unhealthy days of high ozone in this year’s report. Kent County dropped from a “B” to a “C” while New Castle County again earned an “F”.

“Ozone especially harms children, older adults and those with asthma and other lung diseases,” said Stewart. “When older adults or children with asthma breathe ozone-polluted air, too often they end up in the doctor’s office, the hospital or the emergency room. Ozone can even shorten life itself.”

This report documents how warmer temperatures brought by climate change make ozone more likely to form and harder to clean up. This year’s report also revealed that ozone levels increased in most cities nationwide, in large part due to warmer temperatures in 2016, the second hottest year on record in the U.S. 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.

Particle Pollution in Delaware
For New Castle and Sussex Counties, the 2018 report also found year-round particle pollution levels were distinctly lower than in the 2017 report, continuing a steady decrease over at least a decade. Nationwide, the best progress in this year’s report came in reducing year-round levels of particle pollution.  Although this year Kent County posted an “Incomplete” grade, Delaware’s other values were much better than the national standard.

“Particle pollution is made of soot, chemicals, and 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,” said Stewart. “Year-round particle pollution levels have dropped thanks to the cleanup of coal-fired power plants and the retirement of old, dirty diesel engines.”

“State of the Air” 2018 also tracked short-term spikes in particle pollution, as these can be extremely dangerous and even lethal. According to the 2018 report, Kent and Sussex Counties had zero days when short-term particle pollution reached unhealthy levels in 2014-2016, and continued their streak among the nation’s cleanest counties for a seventh straight year.  In addition, New Castle County had few enough days with unhealthy air to return to a passing grade (a “D”). This improvement since the last report continues a general trend toward fewer short-term spikes in particle pollution in Delaware.

In other areas of the country, many of the daily spikes fine particle pollution were directly linked to weather patterns such as drought or to events such as wildfires, which are likely to increase because of climate change.  In some localities, high emissions from wood-burning devices have also been a factor.

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.
