Kinder Morgan Ammonia Nitrate Spill; Wilmington, NC

Source report excerpt: “After being notified on incident, SSC contacted NOAA Seattle to obtain information about mixing of product spilled and oil residue in barge. RP would like to use barge for temporary storage of the spilled product but concerned about reactivity of mixing product with oil residue. SSC contacted Glen Watabayashi to get information on potential for reactivity. Jim Farr contacted SSC and explained that because the ammonia nitrate is a water based solution mixing this solution with the oil residue would not create a hazardous reactivity. This information waqs then passed along to MSU Wilmington.”

They used other storage tanks on the property to hold the rest of the product. 4-5 vacuum trucks were used during the weekend as well as up to 17 tank trucks. The tank is now empty and the company is removing saturated sediment to a tarp covered area. They are looking at options to sell the soil (consulting with USDA) for agricultural application. The company's environmental contractor did conduct core samples […]”
