A Brandon-based chemical plant has been the subject of scrutiny since 2017 as its wastewater disposal methods have resulted in numerous regulatory orders and lawsuits by the cities of Brandon and Jackson.
There's also an ongoing federal investigation that has resulted in one guilty plea.
Gold Commodities utilizes a process to transform used cooking oil and soapstock — which is a malodorous byproduct resulting from the refining of soybean and other oils — into animal feed and biodiesel using sulfuric acid. The wastewater from this process is mixed with caustic material and maintained a high temperature to prevent it from congealing into a pipe-clogging sludge that is also corrosive.
Environmental regulators have now ordered the company to stop dumping its wastewater into Brandon, Jackson and now Pelahatchie.
