Tank Waste Remediation System
This Supplement Analysis addresses the potential effect that new data and information developed since preparation of the Tank Waste Remediation System Environmental Impact Statement (DOE/EIS-0189), hereinafter referred to as the TWRS EIS, may have on the environmental impacts presented in that report to support a determination of whether these new data warrant further National Environmental Policy Act of 1969 (NEPA) analysis at this time. Examples of two changes resulting from the new information included a (1) deferral in single-shell tank (SST) retrieval and (2) expanded capacities for both the Phase I and Phase II pretreatment and vitrification facilities.
