[en] The proposed waste treatment scheme known as the ''Clean Salt Process'' would make it possible to extract sodium salts of very low specific activity from Hanford's low level waste currently stored in underground single shell and double shell tanks. This document explores the regulations applicable to a number of disposition options for the recovered sodium salts. The current (baseline) plan is to vitrify the unrecovered sodium salts along with the low level waste from the tanks. Several options are available for disposition of the recovered salts, at far less cost. These options range from beneficial re-use or recycle of the recovered salts to disposal of the recovered salts as mixed waste at an on-site disposal facility. Federal and state regulations governing each disposition option are presented
