- NATION, Page 29American NotesSMOGPollution Tests On the Run
-
-
- The war against smog may soon get a new high-tech weapon. A
- device being tested in Provo, Utah, uses an infrared beam,
- computer software and a video camera to add up the carbon
- monoxide and hydrocarbons billowing from the tail pipes of
- passing cars -- and to automatically record their license
- numbers.
-
- If the new device proves accurate, it could go into
- widespread use next year, when the Clean Air Act of 1990 will
- require 18 states and 33 cities that have excessive carbon
- monoxide or ozone levels to begin extensive pollution tests,
- including on-road exams.
-
- Some prosecutors think the device could also be used to
- issue pollution tickets to motorists who have deliberately
- tampered with their cars to get around the new rules. But for
- the moment at least, about 100 drivers in Provo face a far more
- desirable consequence if the roadside detector flunks their cars
- twice: private sources will pay for the necessary repairs.
