Underground Tank Closure in Place
An alternative to underground storage tank removal is tank abandonment or “closure-in-place”. To completely remove the tank is often the safest option. However, structural considerations and underground utility placement don’t always allow for this option. Closure-in-place can offer a cost effective solution.
Closure-in-place involves leaving a UST in the ground and filling the tank with a non-hazardous substance, such as sand or concrete slurry. Prior to closure of the tank, soil sampling is performed to ensure there hasn’t been a leak. Any soil contamination must be handled before tank abandonment can begin. The tank is then cleaned of all liquids, hazardous vapors, and sludge. It is bad practice to fill an abandoned tank with water. Since metal tanks are prone to corrosion, this method only causes the tank to corrode faster. Any metals or materials absorbed in the water will eventually leach into the soil. This is why tanks are filled with sand or concrete slurry to prevent a collapse. PMSI offers the safest technology and practices to keep your company and our environment safe from damage.
