The fire from the truck did not spread to nearby buildings, despite earlier reports to the contrary, Comer said. No other vehicles were involved.
Maryland State Police said the truck was carrying gasoline, despite initial reports from police that the cargo was propane.
"Things are getting back to normal," Tome had said late Saturday afternoon. "Utilities are still being restored."
Tome said he was glad no civilians were hurt and appreciated the efforts by people who helped out. He predicted things would return to normal by Sunday.
Tome said he was helping shore up a foreclosed house on Main Street when the crash occurred. Like several people in the area, he took a photograph of the fireball from the explosion with his phone camera.
The area where the crash occurred is at the bottom of a steep hill where Route 222 makes a sweeping curve north to become Main Street, which then runs through the town parallel to the east shore of the Susquehanna River. The town's Marina Park is also by the crash site, as is a freight railroad line owned by Norfolk Southern Railroad, which runs through Port Deposit parallel to the river.
The truck ended up near an open area between the road and the railroad.
Photographs taken Saturday morning showed bits of wreckage remained, and marker paint lines had been sprayed on the ground around where the truck burned. Trains were running again after being kept out of the area following the crash, according to state police.
Delmarva Power spokesman Bill Yingling said 148 customers lost power as a result of the accident.
The majority had their power back by 4 a.m. Saturday. All customers had power restored by 6 p.m. Saturday, Yingling said Sunday afternoon.
The State Highway Administration said Route 222 was re-opened by 6:40 a.m. Saturday morning.
Jay Apperson, spokesperson for the Maryland Department of the Environment, said Saturday morning that the department's emergency response division went to the site and found there was "extremely minimal environmental impact, limited to the burn site."
A person who answered the telephone at Coraluzzo Trucking's offices in New Jersey Saturday morning said there was no one around on the weekends to give a statement.
Fire companies responding to the fire included Water Witch Fire Company of Port Deposit and Community Fire Company of Perryville responded from Cecil County, according to Cecil Fire Blog.
Level Volunteer Fire Company, Darlington Volunteer Fire Company, Susquehanna Hose Company of Havre de Grace and Aberdeen Fire Department, all from Harford County, also send personnel and equipment to Port Deposit, according to Rich Gardiner, spokesperson for the Harford County Fire and Ambulance Association.
Friday's night's crash occurred along the same street where another tanker, carrying propane, went out of control on the steep hill coming down Route 272 on Aug. 14 and overturned at Main Street, before striking the corner of a waterfront condominium building. The truck driver was injured and the building was damaged, but emergency personnel were able to avert an explosion and no one else was injured.
The potential danger posed by accidents involving heavy trucks, as well as trains, many carrying hazardous materials, is a situation Port Deposit's 700 residents have long learned to accept as a condition of living there. The town sits along a narrow area between the river shore and a steep bluff to the east, with a major freight railroad line and a state highway running through it from end to end.
As far as accident concerns on the particularly dangerous stretch of road where Friday's accident occurred, Tome said the town has "done what we can."
The town has "lobbied the state successfully," regarding speed limits, traffic signs warning of the dangerous conditions and attempting to get law enforcement aware of speeding commercial vehicles, the mayor explained. The problem, he believes, is that drivers are "not adhering to the signage."
"We encourage everybody to have awareness," Tome said.
