About 50,000 heavy-duty diesel trucks and buses in California need to be retrofitted with special filters by the end of the year. If the filters aren’t installed, the truck and bus owners face hefty fines.
The vehicles are what the California Air Resources Board calls "heavy, heavy-duty" buses and trucks -like semis and dump trucks that can haul more than 26,000 pounds. Such trucks with engines made from 2000-to-2004 will be required to have soot filters for the new year.
Bruce Tuter is with the California Air Resources Board. He's in Southern California this week trying to get the word out, "Places such as border crossings like we are now, where we're getting out-of-state trucks coming in. Maybe we're at ag stations -again, out of state trucks, or where we know the need for education is the greatest."
Engines made from 1996-to-1999 are already required to have
soot filters.
The filters need to be installed by a professional and cleaned
to avoid loss of engine power.
The state says the emissions of 900,000 trucks and buses that
regularly travel in California must be reduced by 85 percent by
2023.
