The South
Carolina State Underground Petroleum Environmental Response Bank
(SUPERB) Act of 1988 was created to ensure owners and operators
of underground storage tanks (USTs) containing petroleum and
petroleum products had the availability of funds for the
rehabilitation of releases at sites contaminated with petroleum
or petroleum products released from a UST and for administration
of the UST regulatory program. For releases reported to the
Department on or after July 1, 1993 the owner/operator is
responsible for the first twenty-five thousand dollars of any
rehabilitation costs, after which additional funds are supplied
by the SUPERB account for qualified parties, if necessary. As
can be expected, releases posing the greatest identified risk to
human health and the environment receive SUPERB funding
priority.
The SUPERB Act requires that all the costs for site
rehabilitation receive prior approval from the Department. In
addition, any contractor who performs site rehabilitation work
in South Carolina must be certified by the Department. UST
owners or operators are rendered the ability to select their own
certified contractor to perform necessary actions in accordance
with the criteria and allowable costs established by the
Department. HRP’s South Carolina office has been a South
Carolina Department of Health and Environmental Control (SCDHEC)
certified contractor (#007) since 1993.
Through and on-going relationship with an existing client,
Echols Oil Company of Greenville, HRP has positioned itself to
inherit a number of sites currently under the SUPERB program.
Specifically, Echols Oil has begun the acquisition of a number
of regional fuel suppliers as well as service stations. In the
purchase process, Echols Oil has agreed to voluntarily incur the
existing environmental liability for many of these service
stations. In turn, Echols has contracted HRP to serve as the
certified environmental contractor for these sites.
One such site is the Gray Court Exxon, located in Gray Court,
South Carolina. The site had a reported release on August 8,
2001, and was already within the SUPERB program, with the IGWA
and Tier I Assessment previously performed. By request of Echols
Oil, HRP submitted the UST Owner/Operator Lead Information
Sheet, thus becoming the contractor of choice for the site. HRP
submitted a Freedom of Information (FOI) request for all
previous submittals (i.e. the IGWA and Tier I documents) in
order to facilitate the preparation of a technically proficient
and cost efficient Tier II Assessment Plan. Review of the
documents indicated that the site soil and groundwater was
highly impacted with petroleum compounds, with one (1) existing
monitoring well (the original IGWA monitoring well) containing
undetermined amounts of free product.
Based on this information, HRP submitted a Tier II Assessment
Plan to the SCDHEC consisting of 200 feet of soil screening
borings and subsequent sampling to determine the horizontal and
vertical extent of contamination, the installation and
subsequent sampling of nine bedrock wells on the site totaling
575 total feet, as well as aquifer characterization studies.
Based on the submitted Tier II Assessment Plan, SCDHEC approved
the project to allow HRP to characterize the site for Echols and
move forward towards corrective action.
Based on HRP’s in depth knowledge of the intricacies and
regulatory requirements of the SUPERB program, as well as
maintaining a high-quality working relationship with an existing
client, HRP can assist our client with developing a remedial
action plan that will allow for further site development and
economic growth for the property.
