Officials: Paulsboro evacuations extended through Dec. 8th
PAULSBORO, N.J. - December 2, 2012 (WPVI) -- Conrail crews had reports of signal problems at a New Jersey railroad bridge weeks before a train derailment Friday, and were studying the problem the day before the crash and resulting chemical leak, federal investigators said Sunday.
Seventy people went to a hospital following the derailment. More than 100 people are expected to remain out of their homes this week while crews try to remove the hazardous material, vinyl chloride, from a ruptured tanker.
"The evacuation area that is currently in place has been extended through Saturday," Chief Warrant Officer Amy Midgett and the Public Information Officer for the Unified Command for this response said during a press conference by the Coast Guard Sunday afternoon.
Noting that the hazardous material is still in the area, officials said Sunday that the Paulsboro, N.J. residents won't be able to return to their homes in the 12-block evacuation zone until at least Saturday.
The evacuation zone starts at Railroad Avenue and goes south to East Broad Street / Crown Point Road and from North Delaware Street heading east to Mantua Creek.
"We still have containers of vinyl chloride. We're taking all precautions to make sure the community stays safe. As long as we have vinyl chloride and the potential for that release, we're being very cautious for public safety purposes," Coast Guard Captain Todd Weimers said.
Officials hoped to start removing the hazardous material from the ruptured tanker sometime Sunday. It was not clear how long that would take to complete.
"We're starting pump operations today to transfer the material. We don't know how long that is going to take because we don't know what the consistency of the material that is in the container," Weimers said.
Public schools in the southern Jersey town will be open on Monday, and officials said air testing quality will be conducted to ensure students' safety. However, the Head Start Center is closed through Friday.
All Guardian Angels Regional School students currently in the Paulsboro campus are to report to the Gibbstown campus for the remainder of the week. All activities at the Paulsboro campus will be postponed to a later date.
Any residents with questions can call the Paulsboro Community Hotline at 1-800-230-7049.
The derailment Friday sent dozens of people to a hospital, but no serious injuries have been reported.
Federal investigators said Sunday that Conrail crews had studied reported signal problems at the railroad bridge where the derailment occurred.
The National Transportation Safety Board cannot examine the scene until the chemicals are removed. But the agency has begun reviewing records with a focus on both the signal problems reported recently and a 2009 train derailment on the same bridge.
Conrail regularly moves tons of hazardous material over the low bridge, which was originally built in 1873. The bridge straddles Mantua Creek, a tributary near the Delaware River in the industrial town of Paulsboro. The bridge operates like a garden fence, with a section that swings sideways to open for boat traffic, then closes and locks into place for freight trains.
The NTSB expects to focus its probe on that locking mechanism along with the signal devices, which are triggered by sensors on the bridge, not by dispatchers.
"This is a very complex (bridge) operation," Hersman said at a news conference Sunday. "There is a lot of tonnage that goes over this bridge and a lot of hazardous materials."
Conrail crews in recent days and weeks had been reporting problems with the signal, and the rail company had been looking into the problem only the day before, she said.
The veteran two-person crew was familiar with the route and had run it on the three previous nights. They had started their shift at 3 a.m. Friday and were surprised to get a yellow signal when they approached the bridge at about 7 a.m. They used a keypad device, similar to a garage door opener, to try to get a green light, but were unsuccessful. The pair stopped the train for several minutes, examined the tracks, and then got permission from a dispatcher to proceed, Hersman said.
The two locomotives and five cars made it across before the crew looked back to see the bridge "collapse" and a pileup of cars in the creek. The one that ruptured had been damaged by another tanker, Hersman said.
Recordings of various data so far support the crew's account, investigators said. However, authorities are not yet sure whether the bridge deck actually collapsed or shifted.
A team of NTSB investigators arrived in the region Saturday with scanners and other equipment to study the wreckage site, but they cannot get to the scene until the vinyl chloride is removed. The Coast Guard and other authorities were coordinating the cleanup.
The NTSB also plans to review how the bridge was rebuilt after the coal train derailed there in 2009.
Investigators also want to learn if the tidal surge or debris from Superstorm Sandy may have caused problems at the bridge, although the area was not among those hardest hit by the storm.
About 100 people are staying in motels due to the 12-block evacuation, while an unknown number are with friends and family, said state Assemblyman John Burzichelli, a former mayor of Paulsboro.
The bridge usually supports at least three major trains each day serving refineries and other customers in the area. The August 2009 derailment was believed to have been caused by a bridge misalignment.
The tanker that ruptured Friday contained 25,000 gallons of vinyl chloride, some of which spewed into the air, sickening dozens of people. About 70 people went to a nearby hospital complaining of respiratory problems and eye irritation. None of the injuries was believed to be serious.
The remaining gas in the tanker had turned into a solid and settled at the bottom of the tanker.
The removal of the vinyl chloride and the seven wrecked rail cars is expected to be a delicate operation. A huge crane was brought in from New York Harbor to pick up the tanker cars.
