LDEQ, Ascension agree to handle 'red dust' from alumina plant…
The bauxite in question comes from LAlumina, a shuttered plant adjacent to Pelican Point that processes bauxite ores to produce alumina, a precursor to aluminum. The facility, which closed in 2020 due to low alumina prices, dumped its waste products into five large ponds across 500 acres on the facility.
