ARLINGTON, Va. — An initial refinery test showed the ultra-low-sulfur diesel fuel that federal rules will require in four years will not be drastically contaminated in oil pipelines as some had feared.

WASHINGTON — The state of California sets its own environmental laws and will not give heavy-duty diesel engine makers any delay beyond Oct. 1 to make cleaner diesel engines even if the federal government does, a California Air Resources Board official said here last week.

The government's refusal to extend the deadline for requiring cleaner-running diesel truck engines hit the truck manufacturing industry hard last week, as two major fleets said they would cut new truck purchases sharply and a large engine maker warned it would lay off production workers.

William D. Zollars, chairman and president of Yellow Corp., told financial news channel CNBC, Friday that, after improvements in tonnage and freight shipments during the second quarter, business has "flattened in the last six weeks."

Truck engines certified by the Environmental Protection Agency as meeting Oct. 1, 2002 standards may gather dust on the shelves for some time, if the results of an American Trucking Associations survey prove accurate.
