No new capabilities have been added,and none has been deleted. As indicated in Table 2.5.2-1, activity levels for all capabilities during the 1998 to2002 timeframe were less than levels projected by the SWEIS ROD.2.5.3 Operations Data for the Sigma ComplexLevels of research and operations were less than those projected by the SWEIS ROD; consequently,operations data were also below projections. Waste volumes and NPDES discharge volumes were all lowerthan projected by the SWEIS ROD except for chemical waste generated in 2002. Table 2.5.3-1 providesdetails.2.5.4 Cerro Grande Fire Effects at the Sigma ComplexCerro Grande Fire effects on the Sigma Key Facility and its associated operations were minimal. Programsat Sigma did suffer downtime and loss of productivity during the evacuation, initial damage assessment,and recovery and reentry phases. No direct fire damage occurred and recovery was limited to cleaning orreplacement of air system filters.SWEIS Yearbook—2002 2-75
