One Vehicle HazMat-Semi Rollover Leaves Highway 550 Closed South of Silverton

From CSP:

The Colorado State Patrol is investigating a single-vehicle semi rollover on Highway 550 at milepost 69.8. Highway 550 remains closed between milepost 50 at the bottom of Coal Bank Pass and milepost 70 at Silverton.
At approximately 7:30 PM on November 14, 2018, a red Peterbilt truck-tractor hauling a tank semi-trailer lost control while northbound on Highway 550 at milepost 69.8, just south of Silverton. The semi drove across the oncoming (southbound) lane and up a small embankment. The semi overturned onto its right side. The tank trailer separated from the tractor and rolled an additional ½ time coming to rest on its left side, near the road.
The driver of the semi, Micah Rodgers, 45, of Pineville, LA, was transported to Montrose Memorial Hospital for evaluation. The semi, operated by Miller Transporters of Jackson, MS, was hauling stabilized methyl methacrylate monomer (MMA), a very flammable liquid used in a variety of plastics. The tank did not rupture, but an undetermined amount leaked from a valve. Colorado State Patrol Hazardous Materials technicians as well as clean-up and remediation crews are on scene. Plans are underway for an operation to empty the tank before it can be safely righted and removed.
Highway 550 remains closed due to flammability concerns. There are no health hazards or concerns at this time. Motorists and pedestrians will be required to keep a safe distance, behind the road closure. At this time, off-loading, righting, and removal operations will take place in the daylight, and may conclude as early as early afternoon on November 15. Highway 550 will remain closed until that time.
Silverton San Juan Fire and Rescue Authority, Silverton San Juan County Ambulance Association, San Juan County Sheriff’s Office, Durango Fire Rescue, and the Colorado Department of Transportation are assisting with this incident.
