6.2 ConclusionsIn conclusion, LANL operations data mostly fell within projections. Operations data that exceededprojections, such as number of employees or chemical waste from cleanup, either produced a positive impacton the economy of northern New Mexico or resulted in no local impact because these wastes were shippedoffsite for disposal. Overall, the 1998 through 2002 operations data indicate that the Laboratory was operatingwithin the SWEIS envelope.The 1998 through 2002 data indicate that LANL operations typically remained below levels projected bythe SWEIS ROD. There are two main reasons for this fact. The ROD was not issued until September 1999;consequently, operations were more likely to be at levels consistent with pre-ROD conditions. Moreover, datain the SWEIS were presented for the highest level projected over the 10-year period 1996–2005. Thus, thedata from early years in the projection period (1996–2002) would be expected to fall below the maximum.One purpose of the 2002 Yearbook is to compare LANL operations and resultant 1998 through 2002data to the SWEIS ROD to determine if LANL was still operating within the environmental envelopeestablished by the SWEIS and the ROD. Data for 1998 through 2002 indicate that positive impacts (such associoeconomics) were greater than SWEIS ROD projections, while negative impacts, such as radioactive airemissions and land disturbance, were within the SWEIS envelope.6.3 To the FutureThe Yearbook will continue to be prepared on an annual basis, with operations and relevant parameters in agiven year compared to SWEIS projections for activity levels chosen by the ROD. The presentation proposedfor the 2003 Yearbook will follow that developed for the previous Yearbooks—comparison to the SWEISROD. As requested by DOE/NNSA, the Laboratory will include the results of an updated wildfire analysis inthe 2003 Yearbook.The 2002 Yearbook is an important step forward in fulfilling a commitment to make the SWEIS for LANLa living document. Future Yearbooks are planned to continue that role.Wetland in Pajarito Canyon6-6SWEIS Yearbook—2002
