Garretson, S.D. — Winds in excess of 100 mph upended four of six fertilizer tanks at the Koch Nitrogen facility here June 22, according to Fire Chief J.R. Hofer. “We had calls stacking up on each other, but we went on scene to check for spills and found that Koch already had people in the area,” he said. Hofer figures there was less than 100 gallons spilled at the site. The kind of fertilizer spilled was not identified. While Koch declined to participate in the story, the facility, which Koch acquired in 2012 (GM Dec. 31, 2012), is heavily into UAN and starter solutions.
