WFR responds to fuel truck rollover at the intersection of SD Hwy 212 and I-29 at 1203 pm on Thursday Jun 12. Initial report was an 18 wheeler is on its side and the fire is now out with diesel fuel leaking. Upon arrival found that a semi truck / trailer had rolled onto its side from attempting to turn north bound on I-29 from Hwy 212 from the west. The trailer was loaded with approximately 8,000 gallons of diesel fuel and gasoline. The driver was un-injured and was able to climb out of the truck on his own. There were 2 small leaks that the rescue crews were able to stop and contain very quickly. Hwy 212 was closed for traffic immediately and remained partially closed for the entire time of the incident. WFR then assisted the trucking company with offloading the product into another fuel truck. After a little more than 3 hours we were able to get the truck up righted and towed off the roadway so the roadways could be opened back up. We were very lucky with the location and conditions of this accident, referring to the fact that there was a small fire that went out almost immediately on its own, the wind was out of the best direction to allow for safety of the crews to work on the rig, and the weather cooperated very well. It is estimated that 40 to 50 gallons of product were possibly spilled in total of the 8,000 gallons during the 3 hrs. plus incident. This could have easily been a large fire scene. Many agencies assisted with the incident to include WFR, WPD, Cod Co Sheriffs office, Cod Co Emergency Management, SD Highway Patrol, and Magellan Pipeline. The accident is under investigation by the SD Highway Patrol. There were no injuries reported from this incident. SD Hwy 212 was opened back to normal traffic at 1516. Battalion Chief McElhany
