Petroleum Impacted Soils Remediation, Northern New York
PROJECT HIGHLIGHTS:
Use of a slide rail shoring system
Business remained open during remediation
Removal of all site utilities for remediation
Restoration of utilities during backfilling
Excavation and management of 700 tons of contaminated soil
This Northern New York bus station (once a fuel services station) required the removal of petroleum impacts associated with its former use. The site featured a 1,100-square-foot structure currently serving as a Trailways bus station, with subsurface impacts primarily in the front area, among water and sewer utilities, unidentified pipes, and overhead electric lines.
Before intrusive excavation, SES conducted a survey of subsurface utilities using ground-penetrating radar (GPR) and soft dig methods. Twenty subsurface soil borings were then completed at depths up to 15 feet below grade, pre-cleared to 4 feet below grade.
The excavation, done in cells with a slide rail shoring system, reached depths between 10 and 12 feet below grade. Impacted soils were excavated, loaded onto trucks, and transported off-site for disposal at a Shell-approved facility with waste manifests. ORC pellets were spread at the excavation bottom, and clean crushed stone was placed in one-foot lifts and compacted with a remote vibratory roller before moving to the next cell.
Upon completion of backfilling, subsurface, and overhead utilities were restored to the Trailways building, and temporary services were removed. The impacted parking lot was paved, and parking spaces were repainted.
