  Air pollution used to be something Utahns just griped about. That’s changing, according to Kerry Kelly a University of Utah scientist and member of the state Air Quality Board.

Many people think it’s a good idea to idle their cars for a few minutes to warm them up during cold weather. It used to be recommended.

Northern Utah is bracing for the first pollution episode of the new year, thanks to a multi-day inversion that has started building on the Wasatch Front.

State regulators say banning wood-burning in winter would protect northern Utah’s air from harmful pollution. The battle over that idea is about to heat up, about a year after Governor Gary Herbert announced plans to idle wood stoves in northern Utah for the entire winter.

Environmentalists want state regulators to come up with a tougher plan to clean up air pollution in rural Utah caused by coal-fired power plants.

A new study released from the Harvard School of Public Health shows a link between exposure to particulate air pollution and autism.


Atmospheric scientists at the University of Utah have installed an air quality monitor on a Utah Transit Authority TRAX train. It’s helping them get a detailed picture of air pollution around the Salt Lake valley.

Environmental Protection Agency Administrator Gina McCarthy announced plans Wednesday to tighten limits on ground-level ozone pollution.

“The science clearly tells us that ozone poses a real threat to our health,” said McCarthy in a conference call with reporters, “especially to growing children and older Americans and those of us with heart or lung conditions and those who are active or who work outside.”

Regulators are relying on a growing body of scientific information to craft better pollution controls for the energy industry. They’re drawing on some of the results that scientists have gathered on the Uinta Basin’s ozone pollution problem.

Utah’s winter pollution season officially gets underway this weekend, and thanks to $1 million from the Legislature, new research is focusing on what causes the state’s air-quality problems and how to solve them.

A dozen studies will look hard at what makes sooty winter pollution so nasty in Utah and why ground level ozone gets so high. They also will zero in on air chemistry and the weather’s role.

State air-quality officials are still trying to bring next-generation clean cars and clean fuel to Utah. They told lawmakers Wednesday they are making headway.

Ozone pollution in Utah barely reached unhealthy levels this year. The summer smog season ended Oct. 1, and the Utah Division of Air Quality reports none of its 15 sampling sites statewide exceeded the federal cap.

Kevin Seely sometimes gets lunch with his coworkers at downtown Salt Lake City taco cart that’s just a few blocks from where state air regulators monitor ozone pollution. He’s not surprised to learn regulators recorded so few smoggy days this summer, because that’s what Seely saw with his at-home pollution indicator: his four-year-old.

Families all over Utah celebrated Pioneer Day with fireworks. The festivities also pumped lots of unhealthy smoke into the air that spiked air pollution. KUER’s Judy Fahys reports on the trend and Salt Lake City’s plan to deal with it.

Polluted air has become a kind of day-after tradition for Independence Day and Pioneer Day in Utah. Monitors at the state Department of Environmental Quality show those pretty pyrotechnics created enough smoke to top federal health standards in Salt Lake, Utah, Weber, Cache and Tooele counties Thursday night.

Forecasters are predicting nice weather for the holiday weekend. But clear, quiet skies also mean higher ozone pollution that can cause health problems.

Ozone is Utah’s “other” pollution. It’s odorless and colorless. But this summertime pollutant still poses a hazard to health. Bo Call supervises pollution monitoring for the Utah Division of Air Quality.

The sixth annual Clear the Air Challenge begins on Tuesday.  The idea is to help people learn what they can do to help protect the air from pollution. 

July is a big month for Jonathan Johnson. He’s chairman of the board of and he leads the Salt Lake Chamber’s clean-air committee. The pressure’s on because his company edged out perennial rivals Fidelity Investments and ADP to clinch last year’s Clear the Air Challenge in the corporation category.

The Environmental Protection Agency released an ambitious plan Monday to reduce the pollution blamed for global warming. Several Utahns are already working on next steps.

David Folland, a leader of the grass roots Citizens Climate Lobby in Utah, is pleased to see progress finally being made on the issue.

Burning wood in fireplaces and stoves has been forbidden for years whenever air quality gets bad in parts of northern Utah.

Now the Division of Air Quality is considering similar regulations for businesses.

The idea first came up when regulators were brainstorming in a public workshop last winter: Why not make commercial and industrial facilities comply with the same no-burn standards that homeowners do?

Tooele County citizens met Wednesday night to talk about the possibility of letting Stericycle build a new medical waste incinerator in the area. After a series of informational meetings organized by Stericycle, this town hall was organized by residents.

The meeting at Stansbury High School was organized by Katrina Hill of Stansbury Park, who says she’s never done anything like this before.

A midwife in Vernal has brought attention to what she believes is an unusually high rate of infant mortality in Uintah County. She and some environmental activists believe the newborn deaths may be connected to pollution from oil and gas drilling in the area. State and local health officials are holding a public meeting Wednesday evening to discuss a possible study of the issue.

The American Lung Association released its annual report this week on the State of the Air across the country. The results for Utah are mixed.

Utah’s smog season is underway. Some call it Utah’s overlooked pollution problem.

Michelle Hofmann, a pediatrician and founder of the health advocacy group Breathe Utah, is used to hearing people complain about sooty pollution in the winter. But she says it’s harder for patients to grasp the impacts of ground-level ozone pollution, since it’s odorless and colorless.

Researchers, regulators and clean-air advocates gathered Monday to talk about Utah’s air pollution woes.

Jonathan Samet, chairman of Preventative Medicine at the University of Southern California’s Keck School of Medicine, focused his keynote speech on what else decision-makers need to know to build on America’s progress in tackling pollution.

“Research is important,” Samet said after his talk, “and we need it to guide the policymakers, so we can focus in on those sources that may be most critical.”

A new study from the University of Utah suggests yet another link between pollution and health hazards: a correlation between dirty air and suicide that’s spurring even more questions.

Amanda Bakian, an assistant professor of psychiatry, says preliminary findings show more people commit suicide when nitrogen dioxide is elevated. And when is fine-particle pollution is elevated. But she notes the correlation is puzzling because the suicide-pollution link is strongest in the seasons when pollution is generally not that high, spring and fall.

New clean fuel, clean car standards promise to be the single best way to clean up Utah’s air. State leaders say they want to accelerate these so-called Tier 3 rules in Utah. Yet, car buyers are already taking matters into their own hands, at the steering wheel.

Another air-scrubbing storm has just passed through Salt Lake City. But Tom Hemmersmeier is still thinking about clean cars.

Entrepreneurs, activists and policy makers are joining forces Wednesday to solve air quality problems along the Wasatch front. The new Impact Hub Salt Lake is hosting what they call an innovation lab focused on finding air pollution solutions.

Clean air advocates released their grades for Utah lawmakers Tuesday. Compared to past legislative sessions, lawmakers showed improvement, but advocates say there is still a lot of work to be done.

  The Salt Lake Valley was choking with winter pollution as the Legislature convened in January. Lawmakers were compelled to step up to the challenge to clear the air.

Thousands of Utahns rallied for air pollution solutions outside the state Capitol the weekend before lawmakers settled in. No one could remember another time that so many people came together to demand a stop to the smog. Sara Baldwin Auck is an advocate for Utah Clean Energy.
