Project Name: Hydrocarbon
Impacted Soil Remediation Facility
Project Location: Bedford,
Nova Scotia
Owner’s Name: Municipal
Group of Companies
Project Description:
Found in 1992, the Envirosoil
facility in Bedford, Nova Scotia was designed
and constructed to provide a solution for the
treatment and disposal of hydrocarbon impacted
soil and was the first commercial soil treatment
facility in Atlantic Canada. The demand for soil
remediation came into being as a result of leaking
oil tanks and subsequent regulations imposed in
late 1988 requiring operators to remove the tanks
and make reparations. The regulations, enacted
by the Departments of Environment for each of
the Atlantic Provinces, focused on the contamination
of soil and subsequently the underground water
supply from petroleum hydrocarbons.
Initially, contractors were hauling petroleum
hydrocarbon impacted soils to landfills but this
proved unsatisfactory in part because the landfills
were not appropriate disposal and not all jurisdictions
had landfills available.
Initially the Envirosoil facility
was approved for the use of biological treatment
methods to treat impacted soils but by the end
of 1994 this technology proved to be inadequate
for the desired goals of the company. Envirosoil
abandoned biological treatment and procured a
Low Temperature Thermal Desorption (LTTD) unit
in 1995 from Astec Industries located in Tennessee.
At that time, Astec as well as several other major
asphalt plant manufacturers had been designing
and building “soil treatment plants”
for over 10 years in the United States. They had
become popular as a remediation technology due
to the quality, certainty, and timeliness of the
soil treatment achieved.
Although, the Envirosoil facility was originally
designed and constructed to address fuel oil spills
from residential and commercial facilities, the
evolution of the entire environmental and remediation
industry has proven to expand the focus of the
facility. One of the largest drivers behind the
requirement to treat impacted soil is the remediation
that is often required when properties are being
sold. New owners and mortgage companies are often
less likely to buy a contaminated site. The addition
of treatment for Bunker, PAH and PERC have permitted
the facility to provide more solutions to the
remediation.
With the growth of the Offshore Oil & Gas
Industry in Atlantic Canada has materialized another
opportunity for Envirosoil to provide a solution
for the treatment and disposal of Oil Based Mud
Cuttings for offshore drilling activities.
The combined results of brownfield development,
oil & gas exploration and residential and
commercial fuel spill remediation have resulted
in an ever increasing demand for an effective
soil treatment facility in Atlantic Canada and
Envirosoil has the facility to provide the solutions
required.
