RFI investigative activities began on-Site in January 2002 to determine if any impacts exist at the Plant. Supplemental investigations will be completed, as required, based upon the results of the initial sampling activities.

On-Site RFI investigation activities include the following:
• Soil sampling at the surface and below ground
• Groundwater sampling
• Sediment sampling
• Surface water and spring sampling
• Evaluation of on-Site geology
