3.3.2 Chemical WastesChemical waste generation in 2002 was slightly more than one-half of the waste volumes projected by theSWEIS ROD. Table 3.3.2-1 summarizes chemical waste generation from 1998 through 2002.ER Project wastes accounted for 66 percent of the total chemical wastes generated. The ER projects thatcontributed to the waste generated were the removal of contaminated soil at the TA-16-260 outfall and thecompletion of the cleanup of MDA-P.Table 3.3.2-1.

Most of the 14.5million kilograms of chemical waste generated by the ER Project resulted from remediation of PRSs at TA-16,particularly MDA-P. MDA-P was exhumed as part of a clean-closure under the RCRA.dClean-up efforts of the ER Project accounted for the large waste volumes. The continuing clean-up of MDA-P,remediation of PRS 3-056(c) at the upper end of Sandia Canyon in TA-03, and the accelerated clean-up of MDA-Rdue to the Cerro Grande Fire, were responsible for most of the chemical waste generation.eThe continuing clean-up efforts at MDA-P and PRS 3-056(c) accounted for most of the ER Project generated wastein 2001.Radiological worker in respirator and personal protective equipmentSWEIS Yearbook—2002 3-11
