This chapter also discusses Non-Key Facilities, which include all buildings and structures not part of a KeyFacility, or the balance of LANL. Although operations at Non-Key Facilities do not contribute significantlyto radiation doses or generation of radioactive wastes, the Non-Key Facilities represent a significant fractionof LANL. The Non-Key Facilities comprise all or the majority of 30 of LANL’s 49 technical areas, andapproximately 14,224 of LANL’s estimated 26,480 acres. The Non-Key Facilities also employ about half theLANL workforce. The Non-Key Facilities include such important buildings and operations as the CentralComputing Facility, the TA-46 sewage treatment facility, and the Main Administration Building. Table 2.0-17identifies and compares the acreage of the 15 Key Facilities and the Non-Key Facilities. Figure 2-1 shows thelocation of LANL within northern New Mexico, while Figure 2-2 illustrates the technical areas. Figure 2-3shows the locations of the Key Facilities.With the issuance of Nuclear Safety Management (10 CFR 830) on January 10, 2001, on-site transportationalso needs to be addressed relative to nuclear hazard categorization (FR 2001). This is a change from theSWEIS. At the time the SWEIS was published, on-site transportation was considered part of the affectedenvironment in Section 4.10.3.1. The on-site transportation of nuclear materials greater than or equal toHazard Category 3 quantities is addressed in a DOE approved safety analysis (LANL 2002c, DOE 2002a,Steele 2002). The implementation of the analysis and associated controls is under development.Table 2.0-17.
