VIDEO: A fire at an asphalt processing plant resulted in a hazmat situation and evacuations in Camden County, New Jersey early Tuesday. Officials said a large tank containing asphalt began to smolder around 12:45 a.m. at Blueknight Energy Partners on the 200 block of Water Street in Gloucester City. Neighbors said they woke up to a loud bang and their homes shook. Kathy Geiser said she spent all morning in her car with her son worried about their home and neighborhood. "He came running downstairs screaming that he heard an explosion and the asphalt plant around the corner caught fire," said Geiser. "It's scary. It's only a block away." The Gloucester City Fire Department responded to the blaze along with other fire crews. A hazmat unit was also on the scene.
