Underground Storage Tank Removal

Underground Storage Tank Closure Assessment

We started the new year reading a book on Selling 101 (what every successful sales professional needs to know) written by Zig Ziglar. What stood out, from the first few pages, was that the customer is always right and is actually the boss of the seller.  Advice to those seeking to perform Phase I environmental site investigation: Place your order at least a month or two in advance of closing on the property. Delays do occur if environmental issues are reported and are contained in the federal, state and local government database (though rush turn around could be done for an additional fee).

The UST was successfully removed and disposed of at a metal recycling facility.



The view above shows the initial layout of four-inch diameter PVC pipes for a sub-slab depressurization system (SSDS) at an e-designated site in New York City. The pipes are laid beneath a proposed eight-story residential building. SSDS are recommended for sites with soil vapor issues. The system is intended to mitigate soil vapors that could emanate beneath a Site.

For this Site, an active SSDS was recommended due to elevated levels of perchloroethylene (PERC - Tetrachloroethylene) that was detected in post excavation soil vapor samples. The
