For First Time Ever, Johnson City Metro Ranked Among Cleanest Cities in the U.S. for Ozone, Daily and Year-Round Particle Pollution, According to the 25th Annual ‘State of the Air’ Report

For the first time ever, the Johnson City-Kingsport-Bristol, TN-VA metro area was named one of the cleanest cities in the nation for all three measures of air pollution covered in the American Lung Association’s 2024 “State of the Air” report, which was released today. The area earned its first A grade in ozone, and this year’s report also marks the metro area’s fourth consecutive year of posting an A grade for the daily measure of particle pollution.

The Lung Association’s 25th annual “State of the Air” report grades exposure to unhealthy levels of ground-level ozone air pollution, annual particle pollution and short-term spikes in particle pollution over a three-year period. This year’s report includes air quality data from 2020-2022 and is updated to reflect the new annual particle pollution standard that the U.S. Environmental Protection Agency (EPA) finalized in February.

“In the 25 years that the American Lung Association has been doing our ‘State of the Air’ report, we have seen incredible improvement in the nation’s air quality. Thankfully, the Johnson City metro area is listed as one of the cleanest cities for three measures of the most common air pollutants,” said Kevin Stewart, Director of Environmental Health for the American Lung Association. “Unfortunately, across the nation, there are more than 131 million people who live in areas with unhealthy levels of air pollution. Climate change is making air pollution more likely to form and more difficult to clean up. There are actions we can and must take to improve air quality. Many states have made strong commitments to healthy air policies, and the Lung Association supports these policy efforts and opposes policies that would threaten forward progress. We are also calling on the EPA to set long-overdue stronger national limits on ozone pollution.” 

Ground-level Ozone Pollution in the Johnson City-Kingsport-Bristol, TN-VA metro area:

The “State of the Air” report looked at levels of ozone “smog,” the air pollutant affecting the largest number of people in the United States. The Johnson City-Kingsport-Bristol, TN-VA metro area ranked among the nation's cleanest cities for ozone pollution. The ranking was based on the area’s only monitored county’s average number of unhealthy days—0 days per year, an A grade, in Sullivan County, TN. This was better than the area's ranking in last year's report of 111th worst, with 0.3 days per year, a B grade. 

Particle Pollution in the Johnson City-Kingsport-Bristol, TN-VA metro area:

The report also tracked short-term spikes in particle pollution, which can be extremely dangerous and even deadly. The Johnson City metro area ranked among the nation's cleanest cities for short-term particle pollution. The ranking was based on the area’s worst locations’ average number of unhealthy days—0 days per year, an A grade, in both Sullivan County, TN and Bristol City, VA. This was comparable to the area's ranking in last year's report among the nation's cleanest cities, also with 0 days per year, an A grade. 

For the year-round average level of particle pollution, the area’s only monitored location, Bristol City, VA, received a passing grade for pollution levels below the federal standard that was recently updated by the United States Environmental Protection Agency. The Johnson City metro area ranked 178th worst in the nation (tied for 25th best among the nation's cleanest cities). This was comparable to the area's ranking in last year's report of 176th worst in the nation (tied for 22nd best among the nation's cleanest cities).

In addition to the Johnson City metro area, other notable findings include:

• The Knoxville-Morristown-Sevierville, TN metro area remains at its best ever “B” grade for ozone smog, buts its unchanged measure of daily particle pollution and “C” grade ties the metro area for third worst in the Lung Association’s 4-state Midland States region.
• The Virginia Beach-Norfolk, VA-NC metro area (Hampton Roads) ranks among cleanest cities in the nation for daily measure of particle pollution for ninth consecutive year; earns B grade for ozone smog, but worse than last three reports that placed the metro area among nation’s cleanest. 
• The Roanoke, VA metro area continues to rank among nation’s cleanest cities for ozone smog for eighth consecutive year; daily measure of particle pollution remains unchanged at a “B” grade, but worse than several previous reports [eight altogether] that had placed metro area among nation’s cleanest; year-round measure again worsens, but earns passing grade.

The “State of the Air” report found that nationally, more than 131 million people live in an area that received a failing grade for at least one measure of air pollution, and 43.9 million people live in areas with failing grades for all three measures. In the three years covered by this report, individuals in the U.S. experienced the highest number of days when particle pollution reached “very unhealthy” and “hazardous” levels in the history of reporting the “State of the Air.” Communities of color are disproportionately exposed to unhealthy air and are also more likely to be living with one or more chronic conditions that make them more vulnerable to air pollution, including asthma, diabetes and heart disease. The report found that a person of color in the U.S. is more than twice as likely as a white individual to live in a community with a failing grade on all three pollution measures.

Both ozone and particle pollution can cause premature death and other serious health effects such as asthma attacks, heart attacks, strokes, preterm births and impaired cognitive functioning later in life. Particle pollution can also cause lung cancer.

Several states, including Virginia, have made strong commitments to healthy air policies such as Advanced Clean Cars II which would facilitate the transition to zero emission vehicles. The American Lung Association supports these policy commitments and opposes any polices that would threaten forward progress.   

EPA recently finalized new air pollution rules that will help clean up particle pollution and address climate change. Now, the Lung Association is urging EPA to set long overdue stronger national limits on ozone pollution. Stronger limits would help people protect themselves and drive cleanup of polluting sources across the country. See the full report results and sign the petition at Lung.org/SOTA.
