Thank you. After the issue has been studied for quite some time, and quite a bit of comprehensive discussion around this issue, we believe that given current technology, the in situ option that involves freezing is the safest and best, and most advantageous for us. So at this point we are supportive of that, but we don't believe that this is a walk away solution, and we are hopeful that future technology will allow...We are hopeful that at some point the material, the arsenic could be rendered inert or there would be some safe way to get it out of there and move it. At this point we believe that freezing is the safest option, so we are supporting it on that basis. Thank you.
