Executive Summary

The Diamond Green Diesel LLC (DGD) facility is owned by Diamond Green Diesel Holdings LLC, which is a joint venture between Diamond Alternative Energy, LLC (a subsidary of Valero Energy Corporation - 50%) and Darling Green Energy,LLC (a subsidary of Darling International, Inc. - 50%). The facility will be capable of producing 10,000 barrels per day (BPD) of renewable diesel. The feedstock will consist mainly of refined animal fats, recycled cooking oil, and corn oil. The facility includes a Pretreatment Unit, which will remove metals and other contaminants from the feedstock. DGD also includes a small wastewater treating unit, rail and truck unloading facility, and tank farm area.



The DGD also includes the Ecofining Unit, which is a UOP licensed technology, that used Hydrotreating and Isomerization processes to convert the fats/oil feedstock into Green Diesel. This process contains at total of 14,609 pounds of flammables as the maximum intended inventories of vessels and piping and is therefore covered under the PSM and RMP regulations. However, the WCS and ACS have release potentials of less than the threshold of 10,000 pounds of flammables with impact zone of less than 0.1 mile each. The only receptor is the adjacent Valero Refinery. There are no toxic release scenarios.



On August 3, 2014, a fire occurred in the Ecofining Unit at the Diamond Green Diesel (DGD) facility in Norco, Louisiana when a 10" carbon steel pipe on the reactor effluent line near the isomerization liquid mix point ruptured. The failure on the reactor effluent line was caused by hydrochloric acid dew point corrosion resulting from a design configuration that did not account for the reduction in operating temperature at the isomerization liquid tie-in mix point. The carbon steel pipe experienced high corrosion rates in the wet chloride environment operating at temperatures at or near the dew point.
