NTSB Releases Preliminary Report Into Derailment Of BNSF Train Near Doon
(Doon)-- The National Transportation Safety Board has released it's preliminary report into the June 22nd derailment of a BNSF train near Doon that spilled some 230,000 gallons of crude oil.
Investigators say the train was traveling at about 48 mph on tracks designed for 49 mph speeds when the incident occurred. A total of 10 tank cars were breached.
The preliminary report goes on to say that some 5 to 7 inches of rain had fallen in that area during the 48 hours prior to the derailment, washing out track and flooding a tributary of the Little Rock River and farm fields adjacent to the site of the derailment.
The NTSB says the train originated from Rosyth, Alberta, Canada and was destined for a refinery in Houston, Texas. The report says the material that was released was identified as a heavy crude oil with a diluent mixture.
The agency says the investigation is continuing, adding investigators are now examining parts removed from one of that tank cars.
Local officials are paying close attention to the findings of the report. Some contaminated soil and vegetation from the derailment site is being disposed of at the Dickinson County Landfill east of Arnolds Park. The board of supervisors again Tuesday requested a meeting be held with the various entities involved, including the Iowa Department of Natural Resources.
