Abstract : The South Tank From Plume (STFP) is located in the southern half of sections 1 and 2. It is a composite plume of C6H6, MEC6H5, XYLEN, DCPD, and BCHPD which is migrating from the area of Tank 464A. Recent investigations have shown that the STFP is being biodegraded naturally and will not migrate into either Lake Ladora: or lower derby lake prior to implementation of the final remedy. Monitoring with the specific objectives of (1) verifying the rate of migration and (2) locating the leading edge of the plume over the time frame of the Ira is proposed as the preferred alternative action. Sections of this proposed decision document provide summaries of: (1). Site description - history, hydrogeology, extent of contamination (2). Ira objective (3). The IRA project (4). Chronology of events leading to the initiation of the IRA (5) Applicable or relevant and appropriate requirements,standards.
