On December 20, 1987, EPA signed and issued a Record of Decision (ROD) (PB89-225544) for the Tar Pits site, located within the Commencement Bay-Nearshore/Tideflats Superfund Site. A number of changes to the remedy described in the ROD were developed based on studies conducted subsequent to the ROD. These changes are discussed in the Explanation of Significant Differences (ESD) dated November 10, 1991, and also in this revised ESD. This revised ESD is necessary because there have been additional changes in the remedy since the ESD was prepared.
