The driver of a tractor-trailer that overturned at the Bourne South Rotary last week, spilling about 5,000 gallons of gasoline, is being charged with three motor vehicle offenses, State Police said.
Thomas Medeiros, 47, of Westport, faces charges of negligent operation of a motor vehicle, operating at a speed greater than reasonable and proper, and failure to stay within marked lanes, State Police spokesman Dave Procopio said in a statement.
Medeiros was driving a tanker filled with about 11,500 gallons of gasoline when it overturned at about 11 p.m. on March 24, State Police said. The accident forced the rotary and the Bourne Bridge to close for about 10 hours, according to State Police.
Partial closures continue as environmental cleanup proceeds in the rotary area, Procopio said.
State Police said the accident occurred when the southbound tanker exited the Bourne Bridge but failed to make the turn into the rotary and instead continued straight ahead, jumped the curb, and struck the embankment.
Crews from the state Department of Environmental Protection, which began a cleanup Wednesday, will be continuing their work for “at least a number of days this week,” said Ed Coletta, a spokesman for the agency.
“The main focus at this point is the gasoline that spilled from the tanker into the soil within the infield of the rotary,” Coletta said.
Crews have removed about 1,200 cubic yards of contaminated soil so far, Coletta said. They are digging at least 8 feet deep into the area, he said.
Some of the gasoline also drained into catch basins and flowed into the Cape Cod Canal.
The drains were flushed and crews vacuumed a small amount of gasoline off the surface of the canal, Coletta said.
Authorities are also keeping an eye on nearby wetland areas for possible contamination, he said.
