Atlanta Environmental Management, Inc., (AEM) performed
emergency corrective action for No. 2 fuel oil-contaminated
soil and
free liquids in an area adjacent to a 400,000-gallon above-ground
No. 2 fuel oil storage tank. During a three-day period in
February 2000, AEM was responsible for the immediate development
of the corrective action plan and implementation of the
cleanup
of contaminated soil and free liquids at the site. The tank
is located approximately 100 feet from a major coastal waterway.
The fuel oil tank is located within an earthen secondary
containment diking area covered with an impermeable synthetic
liner. A drainage pipe equipped with a valve was used to release
storm water that collects inside the containment area. Subsequent
to a heavy rain, the facility's staff noted a release of fuel
oil caused by the valve that apparently clogged and released
rainwater mixed with oil. It was critical that the contamination
be removed as quickly as possible, due to the proximity to
the Savannah River.
AEM immediately implemented corrective action to address
the oil release. The corrective action included the 1) excavation
of visibly contaminated soil, 2) removal of
free-floating fuel oil on the standing water in the drainage
ditch, 3) proper off-site transport and disposal of the
excavated soil as a special waste, 4) re-grading the excavated
area with clean fill, and 5) re-vegetation of the area using
native flora. AEM documented the sealing of the stormwater
release pipe so that any future storm water that collects
in the containment will be manually pumped from the containment
area for disposal or treatment.
AEM successfully achieved all goals regarding the emergency
response activities to the fuel oil spill. The stormwater
release pipe was repaired to prevent future releases from
the fuel oil containment area. The contaminated soil and free
liquid fuel oil were removed from the release area. Due to
the expedient cleanup, the adjacent area was not impacted
by the fuel oil release. The removal of the contaminated soil
and free liquids also eliminated the possibility of gradual
subsurface migration of fuel oil contaminants in the critical
area near the river.
