The strict emission policies
unanimously approved Oct. 25 by California's Air Resources Board won't take
effect until 2007. When the rules do kick in, however, the states says the
inclusion of required clean air devices will add from $2,000 to $6,000 to
the cost of each truck and bus.

on Oct. 25 take aim at reducing the amount of pollutants emitted by diesel
engines, which are used in most big rigs, buses, trash trucks and other large
commercial vehicles. The rules would bring California in line with standards
set by the federal Environmental Protection Agency.
"These new regulations
will reduce diesel soot and smog-forming emissions from new, large diesel
engines by another 90 percent," said Dr. Alan Lloyd, Chairman of the
California Environmental Protection Agency's Air Resources Board (ARB). The
agency says it plans to reduce emission reductions by equipping new diesel
engines with exhaust after-treatment devices. The state estimates the devices
will add from $2,000 to $6,000 to the cost of each vehicle.
Jerry Martin, a spokesman
for ARB, said one of the things the group hopes to accomplish is to revamp
all old heavy-duty vehicles. "We expect to increase the fuel efficiency
of trucks, he said. "If we can't retrofit them, we hope to get rid of
