DES MOINES -- The DNR's new program that allows citizens to call in license numbers of vehicles with smoking tailpipes is a hit, according to state officials.

"Over 400 calls, emails and faxes have been submitted since this summer," said Brian Button, DNR air information specialist. "We've been pleased to have so many citizens respond."

After an Iowa license number is reported, the vehicle owner is sent educational materials to help them identify the probable causes of smoke and potential repairs. He said repair choices are left to the owner.

"The program is totally voluntary. Similar efforts in other states show about half of those reported will take action. That's a good number for a voluntary program." He said people decide to take action after learning smoke can be unburned fuel, caused by a malfunction or that delayed action can lead to more serious problems. He noted some repairs have pocketbook benefits such as higher resale value, longer vehicle life and fuel savings.

"Of course some vehicles aren't worth extensive repairs. But sometimes a simple tune-up or air filter change makes the difference. At least the owner can make an informed choice with the materials," said Button.

Over half of all toxic air emissions in Iowa come from mobile sources versus smokestacks. The majority comes from cars, buses, trucks and other vehicles. Button said the program helps maintain Iowa's air quality by cleaning up the heaviest emitters. "One smoking tailpipe can emit the same as 25 properly running cars," he said. And with statewide vehicle usage and annual miles traveled projected to keep increasing, the program helps offset emission increases.
