Terracon developed Spill Prevention, Control, and Countermeasure (SPCC) Plans for more than 200 sites owned by Wisconsin Public Service Corporation. The sites include electrical substations, hydroelectric facilities, coal, gas, and nuclear power plants and warehouse/garage facilities. Using resources from multiple offices, Terracon completed visits to each of the sites within a two-month period. Various types of petroleum-containing equipment were observed at these sites, including oil-filled electrical equipment, aboveground storage tanks (ASTs), drums, lube oil reservoirs and oil-containing generating turbines.
Terracon identified petroleum-containing equipment, along with probable drainage routes and surface water receptors in case of potential spills. Equipment containment structures were identified and measured for spill prevention purposes. The site characteristics were entered into personal digital assistants (PDAs) during site visits and were then downloaded from the PDAs to a database. SPCC Plans were created and linked to the database so that the SPCC Plans could be developed in a limited amount of time and in a cost-effective manner.
