On June 26, 2019 EPA received a call from the South Dakota Department of Environment & Natural Resources (DENR) requesting assistance with a 900-gallon pesticide spill resulting from the rollover of a flatbed tractor trailer. The trailer had rolled over next to the Big Sioux River. The tractor trailer also ruptured the diesel tanks causing a discharge to the road ditch adjacent to the River. The State Patrol, the Sheriff’s Department, and County fire and EMS all arrived on Site to assess the situation. A containment berm was constructed around the area of the crash to help contain spill contaminants by the county.

An EPA Region 8 On-Scene Coordinator (OSC) and START contractor were deployed and arrived on-scene on June27, 2019. The OSC will meet with the South Dakota Department of Environment & Natural Resources (DENR) to continue to assess and provide oversight.
