摘要

Based upon this latest thorough review of the historical and current data base for Tanks 107-B, 110-B, 201-B, 101-C, 110-SX, 108-T, 111-T, 101-TY, and 112-U, Rockwell finds that Tanks 107-B, 201-B, 101-C, and 112-U should be relcassified as Confirmed Leakers. The volumes of liquid waste estimated to have leaked from these four tanks are: (1) Tank 107-B, 8,000 gallons (May 1968 to August 1969); (2) Tank 201-B, 1,200 gallons (April 1968 to June 1971); (3) Tank 101-C, 17,000 to 24,000 gallons (January 1968 to December 1969); and (4) Tank 112-U, 7,000 to 10,000 gallons (February 1969 to March 1970). Tanks 110-B, 110-SX, 108-T, 111-T, and 101-TY should continue to be classified as of Questionable Integrity. (ERA citation 05:013171)
