PURPOSE: To consider retaining services of an environmental engineering firm to provide
technical services for preparation of a Limited Site Assessment Report (LSA) to the Ground
Water Section of the State Division of Water Quality.
BACKGROUND: Following construction of the automated fueling station at the Orange County
Public Works complex in 1997, the previous underground storage tanks (UST) and fuel pumps
were permanently closed and. removed on May 14, 1997. At the time of closure, three
underground storage tanks were removed. Soil sampling at the time of UST closure indicated
elevated concentrations of petroleum products were. present. In accordance with State
regulations, a required report was completed and submitted in May 1997 to the North Carolina
Department of Environment, Health and Natural Resources, Division of Water Quality, Ground
Water Section.
In August 2000, the North Carolina Department of Environment and Natural Resources,
Division of Waste Management, contacted the Public Works Department in follow-up to the
report the County submitted 3 '/2 years ago. Since 1997, potentially contaminated soil that was
excavated by the motor pool contractor from the area surrounding the old storage tanks
removed in 1997 has been .retained in a segregated area at the Public Works Department,
pending disposition instructions from the State. The State's UST Section recently advised that
a Soil Contamination Report and/or Limited Site Assessment Report (LSA) must now be
prepared and submitted to ascertain whether there is any remaining contamination in the
immediate vicinity of the 1997 tank excavation. Public Works Director Wilbert McAdoo recently
requested and received a 90-day extension to the 90-day deadline established in the August
2000 DENR letter, to allow completion of required work.
No member of County staff has the requisite technical knowledge and expertise to carry out the
highly specialized analytical work that must be done to support this latest report submission to
the State. Proposals were requested from several environmental engineering companies to
complete the necessary technical work to allow preparation of these reports. Proposals fior
provision of technical services were received from three firms -Engineering Consulting
Services, Ltd.; Quantum Environmental, Inc.; and Trigan Engineering Consultants, Inc. These
proposals are. reflected in the attached 'Bid Summary.
The staff recommendation to select Quantum Environmental Inc. is based on that firm's
demonstrated ability, qualifications and cost for providing the services required by the County.
FINANCIAL IMPACT: Quantum Environmental, Inc. submitted the lowest cost proposal far the
services outlined above. The company's proposal totals $18,145. Staff also requests
authorization of $2,500 for change orders, bringing the total project cast to $20,645. Funds to
cover $15,000 of the proposal cost are included in a previously approved County capital project,
Fuel Tank Replacements. Remaining funds for the proposal can be accommodated in the
current year Public Works budget.
RECOMMENDATION(S): The Manager recommends that the Board approve the bid award for
preparation of a Limited Site Assessment to Quantum Environmental, Inc. in an amount not to
exceed $18,145 and authorize the Chair to sign a contract with Quantum Environmental, Inc.,
subject to final review and approval by staff and the County Attorney, and that the Board also
authorize the Manager to sign any change orders for additional work required, in an amount not
to exceed $2,500.
