PITTSBURGH — A federal judge says a trucking company’s insurer must cover some of the claims associated with the spill of a sticky goo over a 40-mile stretch of the Pennsylvania Turnpike last year.

U.S. District Judge Joy Flowers Conti said Hallmark Specialty Insurance must pay for all nonpollution related claims against MTS Transport over the Nov. 22 spill. A tanker hauling asphalt flux spilled the substance over a stretch of the Turnpike from New Castle to Oakmont. An estimated 1,000 vehicles were damaged by the goo.

A Pittsburgh newspaper said MTS said the insurance plan wasn’t enough to cover all the claims and Hallmark had refused to pay out on a $4 million excess liability policy.
