(AP) Cleanup crews have removed the soil impacted after a Tuesday train derailment in northern Ohio damaged a railcar that leaked flammable liquid and forced the evacuation of hundreds of homes.

CSX Corp. spokesman Gary Sease said only five homes remained unoccupied as of yesterday. Authorities were attempting to reach those residents to let them know they could return after air testing at their homes.

Sease says environmental teams monitoring the air have determined it safe for those already allowed to return home.

The railcar damaged in the derailment in Willard leaked about half of its 26,000 gallons of styrene monomer, which is used to make plastic and rubber products. Willard is about 65 miles southwest of Cleveland.

Sease says an outreach center opened Saturday to answer residents' questions about compensation claims.
