At the time of closure, three <br />underground storage tanks were removed. Soil sampling at the time of UST closure indicated <br />elevated concentrations of petroleum products were. present. In accordance with State <br />regulations, a required report was completed and submitted in May 1997 to the North Carolina <br />Department of Environment, Health and Natural Resources, Division of Water Quality, Ground <br />Water Section. <br />In August 2000, the North Carolina Department of Environment and Natural Resources, <br />Division of Waste Management, contacted the Public Works Department in follow-up to the <br />report the County submitted 3 '/2 years ago. Since 1997, potentially contaminated soil that was <br />excavated by the motor pool contractor from the area surrounding the old storage tanks <br />removed in 1997 has been .retained in a segregated area at the Public Works Department, <br />pending disposition instructions from the State. The State's UST Section recently advised that <br />a Soil Contamination Report and/or Limited Site Assessment Report (LSA) must now be <br />prepared and submitted to ascertain whether there is any remaining contamination in the <br />immediate vicinity of the 1997 tank excavation. Public Works Director Wilbert McAdoo recently <br />requested and received a 90-day extension to the 90-day deadline established in the August <br />2000 DENR letter, to allow completion of required work. <br />No member of County staff has the requisite technical knowledge and expertise to carry out the <br />highly specialized analytical work that must be done to support this latest report submission to <br />
