10/27/05, Anchorage Daily News, The City wants to borrow your car; I/M study to start next week, by Doug O'Harra. The Department of Health and Human Services will be conducting a study this winter to find out how well the I/M program works. Between Nov. 1 and April, contractors will test more than 200 vehicles - 1996 or newer -- that initially fail the I/M test on a special emission system at a municipal I/M station off B Street. The test will measure CO emissions from the failed vehicle during simulated winter driving conditions, and then test the vehicle again after the owner has gotten it fixed. **** See details in article.

• Oxygen Sensor Replacement Study

  12/29/02, Fairbanks Daily News-Miner, Heartland Magazine "Oxygen Sensors May improve our air," by Ned Rozell, Alaska Science Forum, Geophysical Institute, University of Alaska Fairbanks. Replacing oxygen sensors in cars and trucks may make the air in Alaska's cities cleaner. **** See details in article.

Background information on oxygen sensor replacement - The oxygen sensor is an important component in controlling CO emissions from motor vehicles. Replacement of oxygen sensors in high mileage vehicles that originally met the 50,000 mile durability standard has been identified as a potenetial area for controlling CO emissions in Fairbanks. **** See background for additional information.
