- To curb pollution, the EPA demands tougher auto-emissions testing
-
-
- The Bush Administration may be making life easier for
- industries that pollute the air -- but not for motorists. Though
- the White House last month issued an environmental regulation
- enabling businesses to sidestep provisions of the 1990 Clean Air
- Act, the Environmental Protection Agency has now issued a rule
- that will enforce part of the same measure by requiring tougher
- emissions tests and more expensive repairs for car owners.
-
- The proposed regulations, which become final in November,
- require 55 new urban areas to begin testing emissions from cars
- and light trucks by next July. That would bring to 177 the
- number of regions conducting such tests. And in about 80
- metropolitan areas with the worst air problems -- home to more
- than 60 million automobiles -- the test will be made much
- tougher. The simple tail-pipe gauge that measures exhaust while
- the engine idles will be gone. The new test requires a high-tech
- treadmill device with the Jetson-ish name dynamometer. It
- collects exhaust while the car idles, accelerates and brakes.
- Then it runs the material through computerized equipment so
- sensitive that millions of cars now capable of passing
- inspection are likely to fail. And not just old smokies: the EPA
- estimates that as many as a third of recent-model cars will
- flunk, instead of the current 8% to 10%.
-
- The EPA had good reason to issue the new rules. More than
- 20 years after the government began requiring annual emissions
- tests for many cars, half of the smog and 90% of the carbon
- monoxide in the air still pours out of tail pipes; the rest
- comes mainly from the smokestacks of factories and oil
- refineries. The new regulations could reduce smog-producing
- emissions and carbon monoxide pollution from vehicles by 30% in
- many cities. But repairs to pass the test could cost drivers
- from $25 to $450, a stiff increase from the present average of
- $50 to $75. (Anyone whose car still can't make the grade even
- after an outlay of $450 will get a waiver until the next
- required test.) Maybe that kind of expense would be less painful
- if industry were also paying its share.
