EIS-0189: Supplement Analysis

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.
