The 1997 ESA revealed no indications of recognized environmental conditions. The 1998 ESA concluded that operations on the Control Data Campus did not pose a significant environmental concern. However, it was the recommendation of the 1998 ESA that a limited subsurface investigation be conducted in the vicinity of the former fuel oil underground storage tanks (USTs) and that sampling of elevator hydraulic fluids for polychlorinated biphenyls be conducted. A Spill Prevention Control and Countermeasures (SPCC) Plan and Risk Management Plan (RMP) was recommended for the Control Data Systems operations occurring on the site at the time of this ESA. The Guidant Corporation has an SPCC and RMp for their operations. . A subsurface investigation in the former UST area (identified in the 1998 ESA) was conducted. Fuel oil impacts were noted in two of the boring locations. Further investigation was conducted at these locations and it was determined that the impacts were limited to the shallow subsurface soils. The fuel oil impacted soils were removed and the MPCA stated that no further action was required related to the former fuel oil USTs. A liquid oil sample was taken from each of the four elevator hydraulic oil reservoirs. The test results revealed there were no concentrations of polychlorinated biphenyls (PCBs) at or above laboratory method detection limits and therefore, no recommendations were provided for further investigation. No further studies have been completed by Guidant for the remainder of the Guidant Campus not included in the aforementioned ESA's; however, in September 2001, as part of . the completion of the Arden Hills Local Storm Water Management Plan (February 2002), the Minnesota Pollution Control Agency provided the City of Arden Hills information regarding contaminated site in the vicinity of Arden Hills. No sites of concern were identified on or immediately adjacent to the AUAR study area. It is not anticipated that other environmental hazards will be encountered on the Guidant Campus site. 10.
