Ecology Ponders Hanford Tank Farm Closure

By Jeff Lyon, Nuclear Waste Program
I have some questions as Ecology’s Tank Systems, Operations, and Closure Project Manager:

How long should we wait to close the 149 single-shell tanks (SSTs) at Hanford?
What are the risks to humans and the environment if we wait?
If we wait for more money or better cleanup technologies (we may never get either), what should we do about the current soil
