Firefighters and hazmat crews responded to the spill near East 30th Street around 11:45 a.m., according to a fire department spokesperson. A truck owned by the company, Approved Oil, had a hose connected to a building on the block before its haul spilled all over the roadway, bystanders said. “That was when the oil started spilling,” said Millo, 70. Diellza Krasniqi said a man riding a bicycle slipped and crashed when he ran over the slick. “Some of the passerbyers were getting into the bike lane and trying to stop people from riding in the bike lane.”
