California ARB passes new diesel emissions standards

| 10/30/2001

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.

The ARB approved rules 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 them."
