The temporary off-site shipment of hydrolysate, the wastewater product of the Pueblo Chemical Agent-Destruction Pilot Plant neutralization process, came to a successful conclusion Sept. 6.
“This took a huge effort before we transported a single gallon and much attention to detail during the transportation and receipt,” said Greg Mohrman, site project manager, PCAPP.
A total of 236,473 gallons of wastewater were transported in 52 truckloads from PCAPP to Veolia Environmental Services Hazardous Waste Incinerator, Port Arthur, Texas, for treatment and disposal, Mohrman said.
The shipments, which began on July 31, were scheduled to conclude at the end of August. However, Hurricane Harvey disrupted the transportation route and delayed delivery the final three truckloads.
Prior to the hurricane, 222,374 gallons of wastewater in 49 truckloads were safely transported. Although the Veolia facility experienced heavy rains, preparations made in advance of the storm allowed for a successful resolution, said Paul Dent, performance improvement manager, PCAPP.
“The shipments were well coordinated amongst PCAPP operations, operations waste management, Veolia and Tri-State Motor Transit,” said Dent.
This temporary shipment project involved one storage tank of material unsuitable for use in pilot testing, Mohrman said.
Late last year, challenges with Brine Concentrator Feed Tanks resulted in a pause to pilot testing of the Biotreatment Area (BTA), leaving a large quantity of untreated hydrolysate in storage tanks.
