Past Project #1: Decommissioning of Underground Odorant Storage Tanks
Location: Nebraska
MRR was contracted to remove two underground 4000- and 5000-gallon odorant storage tanks and several above-ground smaller tanks. The remaining odorant in the tanks was filtered and transferred to another station for re-use using MRR bobtail truck.
The project included the odorant transfer, tanks’ decommissioning, excavation and back-filling. Afterwards, the tanks were brought to Philippi, WV for thermo-chemical treatment, i.e. to decontaminate them from residual mercaptan. The tanks were then recycled for metal.
In other cases with large underground odorant tanks, depending on environmental constraints, the client may opt to have MRR perform on-site treatment of the tanks, then fill them with an inert (e.g. sand) and abandon them.
MRR hires and coordinates the work of local contractors for excavation, loading, etc, within the requirements of the gas company.
