Axios Des Moines: A fertilizer manufacturing and storage facility would be constructed on Des Moines’ south side — across the road from an airport clear zone — under a proposal that goes before the City Council this evening. Fertilizer plant emergencies can result in widespread safety and environmental contamination. The proximity to the Des Moines International Airport elevates safety concerns, Councilperson Josh Mandelbaum told Axios Friday. Spraytec Fertilizers would construct a $7 million, 51,000-square-foot manufacturing, warehouse and office facility at 7404 SW 37th St. under the proposal. The facility would be the headquarters for the Brazil-based company’s North America production.
