Tips are offered to help clean air

As summer heats up, many Utahns will change the temperature of the air by turning on swamp coolers or air conditioners.

It's pretty simple — just flick a switch for cool air.

But two state agencies want them to know they can also change the quality of their air.

And it's almost as easy — just modify a few habits and change a few behaviors for clean air.

"The summertime is a very popular time for people to drive," said Dianne Nielson, executive director of the Utah Department of Environmental Quality. "It's also one of the highest air pollution times.

"Emissions from vehicles cause about 50 percent of our summertime smog."

Nielson and Utah Department of Transportation director John Njord joined forces Tuesday to remind Utahns they can do a lot of little things that will add up to make a big impact on both air quality and traffic congestion this summer.

"We can all make a difference collectively, as individuals," Nielson said. "The decisions you make as an individual are the choices that help us all keep the air clean and keep congestion off the roads."

The most helpful decision Utahns can make, Nielson said, may be difficult for most people: "If you can, park your own vehicle. Don't drive."

But if that measure seems too drastic, there's still plenty that can be done, including:

Keep your vehicle tuned up. Replace the air filter and keep the tires properly inflated.

Refuel only when it's cool, in the morning or evening, and don't top off the tank. Make sure the gas cap closes tightly; if not, replace it.

Don't allow your car to idle. Avoid using drive-through windows, and when you must, turn off the ignition while waiting.

Accelerate gradually, not quickly, and obey speed limits.

Avoid sitting in traffic. Don't drive during rush hours, if possible.

Be sure your car's catalytic converter is hooked up and operating normally.

Another way to help, Njord said, is to cancel one or more errands, short trips or other outings that may have been planned or contemplated.

"You can choose to skip a trip. Just don't make that trip," he said. "You can choose to use transit. . . . You can also choose to walk or ride a bike."

Njord brought along his Chevy Impala and demonstrated how to check the car's oil level and tire pressure. Both should be done regularly, he said.

"Knowing your vehicle is really important to improving air quality," he said.

He said proper planning for any vacation or road trip is vital, as well.

"Planning your trip in advance can help you avoid road construction and traffic accidents, not to mention make your trips quicker," Njord said.

With high temperatures in the mid- to upper 90s all week, it might be a good time for Utahns to see if they can flick the switch and start cleaning their air.
