The north side of Mosaic Fertilizer’s large phosphogypsum stack at its Uncle Sam plant rises in 2015 near Convent in St. James Parish. At the time, the stack was 187 feet high. It holds phosphogypsum, a waste byproduct from processing phosphate rock to make fertilizer. State officials said Friday, Jan. 25, 3019, that parts of this wall are shifting slowly and could be at risk of collapse. The wall holds back acidic process water from the plant.
