Project Description                                                                                                       

AECS has been awarded multiple contracts by the US Postal Service Facilities Service Office in Atlanta, GA to remove underground storage tanks (UST), fueling facilities, contaminated soil, and all associated electrical and plumbing fixtures and other appurtenances associated with these facilities at various facilities located in Georgia, Alabama, and Florida.  In many instances AECS replaced the USTs with aboveground storage tanks (AST). 

Specific Projects:

USPS Waycross, GA – VMF, UST Removal/AST Installation

AECS was contracted by the US Postal Service to remove underground fuel and oil storage tanks and install an above-ground waste oil storage tank at its Waycross, GA Vehicle Maintenance Facility.   

The project involved the removal and disposal of brine, free product and sludge; the demolition and disposal of a concrete covering; the excavation and removal of one 2,000-gal and two 1,000-gal underground fuel storage tanks and the closure in place of one 300-gal underground waste oil storage tank.

When the tanks had been removed, the soil was sampled and analyzed, and it was discovered that they had leaked and contaminated both the soil and ground water. It was then necessary to excavate, load, transport and dispose of over 100 tons of contaminated soil and over 1,000 gal of contaminated groundwater.

AECS installed a 280-gal aboveground waste oil storage tank; backfilled the excavations; and restored the site with placement of asphalt and seeding, fertilizing, and mulching impacted grass areas.
