Evacuations have been ordered for a few residents who live south of Melissa after a chemical spill along state Highway 5.
The single-vehicle crash took place shortly after noon when the small tanker truck rolled down an embankment and spilled it's load.
The driver, who suffered minor injures, was transported to an area hospital and is expected to be OK.
Markings on the truck indicate it is owned by Douglass Distributing. A hazardous chemical placard for flammable Class 3 1268 petroleum distillates could be seen on the truck's tank.
Officials said the truck was believed to be carrying mineral spirits or other common household petroleum-based products.
The crash is located south of the intersection of Highway 5 and Collin County Road 275 south of Melissa and north of McKinney. There are several homes about a half-mile to the northeast of the crash site and residents are being sheltered at the First Baptist Church on W. Louisiana Street in McKinney.
Most of the residents who live near the crash site are believed to be at work. So far, only 3 people have been evacuated, officials said.
Highway 5 is closed between Farm-to-Market Road 543 and state Highway 121 while crews wait for a private HAZMAT cleanup team to clear the scene.
There is no word on when the roadway will open.
