| | News Release: 1990-06-14 ARB Tightens Tailpipe Emission Limits for Light Trucks |
 | | The standards, phased in over the 1995 and 1996 model years, would reduce emissions of smog-forming hydrocarbon and nitrogen oxide, as well as carbon monoxide, by 223 tons per day, compared to the 15,000 tons emitted by all vehicles in the state every day. |
 | | Vehicles covered by the new standards, however, would have their emissions cut from 26 to 75 percent, depending on the model and its curb weight. |
 | | Besides approving the tighter tailpipe limits, the ARB also doubled the amount of time that manufacturers must meet them, from 50,000 miles to 120,000 miles, after research showed that the vehicles are driven an average of 140,000 miles during their road life and emit 70 percent of their pollution past the 150,000 mile mark. |
