The driver of a tanker truck carrying liquid asphalt discovered what many weekend motorists in the Bay Area know all too well. Once you get lost and turn off a main road in the Santa Cruz Mountains, things can get dicey pretty quickly.

And, the lesson came at a steep cost. The U.S. Environmental Protection Agency has imposed a $60,000 penalty on a Sacramento construction company after one of the company’s tanker trucks rolled down a ravine while trying to negotiate a tight turn on a narrow, winding road near Portola Redwoods State Park in San Mateo County last fall. The crash sent roughly 1,000 gallons of asphalt emulsifier, an oily black chemical poured on roads as part of paving projects, flowing into a creek.
