It looks like it was just an initial stakeholder meeting. With low level radioactive waste there are 3 classes based on isotopic characteristics (A, B, C, with A being the least toxic, C the most). The Utah-based EnergySolutions site can only accept Class A. If one dilutes Class B and C waste with larger quantities of very low Class A waste, all of the waste can fall within Class A and be disposed of there.
Historically, the saying "dilution is the solution" hasn't been well received.
