Political controversies Responding to the immediate after-effects of the accident was the Unified Command response team. This group consisted of representatives of the U.S. Coast Guard, New Jersey Department of Environmental Protection, New Jersey Office of Emergency Management, the Paulsboro Fire Department and Conrail. However, the New Jersey Senate President Stephen Sweeney gave the response team an "F." Sen. Sweeney asserted that the team delayed scheduling public meetings, and that the team issued conflicting and confusing orders in the wake of the derailment. Additionally, area residents criticized Governor Chris Christie for giving inadequate attention to Paulsboro's environmental problems and that they concentrated more of their attention on Hurricane Sandy (which struck New Jersey on October 28–29). They complained that he did not visit Paulsboro and that instead he sent Lt. Governor Kim Guadagno. Area Congressional Representatives Rob Andrews (NJ 1st-D) and Frank LoBiondo (NJ 2nd-R) visited the area and expressed concern and surprise that federal, state or local laws require public oversight of private safety inspection procedures. Following the incident, Congressman Andrews criticized policies that may have led to the accident. He said that it was time to end the railroads' "culture of self-regulation . . . . We've got to come up with a sensible set of regulations." He also criticized the Unified Command's operation as confusing and ineffective. "When everyone's in charge, no one's in charge." Andrews also said that he expected Congress to hold hearings on the causes of the derailment and the response. Legacy The National Transportation Safety Board in a public hearing faulted the first responders for their actions. The investigators said that local authorities did not follow standard procedures for cleaning a chemical spill and that first responders were not provided proper breathing apparatuses, even though monitors indicated unsafe levels of chemicals in the air. They said that this led to further exposure of the first responders and the public to the vinyl chloride gas. Paulsboro police reported the gas as non-toxic, even after fire officials learned that the gas was highly flammable and dangerous to breathe. In March 2013, Conrail announced that the bridge would be replaced with an expected September 2014 operational date. Normally, between March 1 and November 30 the bridge would be left in the open position for maritime traffic and closed when trains approach. It remained locked in the closed position until the bridge was replaced. The new bridge
