E.3.4 Hazardous Chemical Risks/Effects Calculations (continued)

Tables E.3.4-1 through E.3.4-30 show the chemicals associated with the various activities and the various sites considered for each alternative. The increment added by each activity to the site is totalled to show how much the risk at the site would increase should that alternative be implemented. Calculations used to derive the hazard indices for workers and for the public are presented as footnotes to each of the appendix tables. In addition, the slope factor used to calculate the cancer risk for workers and for the public are presented as footnotes in the appendix tables, and the footnotes to the tables show how the cancer risk was performed.

The following chemicals have not been subjected to hazard quotient or cancer risk analysis. They were contained in a list of chemicals used at Pantex for reporting to the State of Texas under SARA Title III. In all cases, the emissions were estimated using product throughput for 1993. They do not represent employee exposure. Therefore, the chemicals remain listed, but are not included in calculations for hazard index and cancer risk to the public and the onsite worker.
