NBCRightNow.com -- A spokesman for Oregon Senator Ron Wyden says the senator will ask the Government Accountability Office to investigate a monitoring and maintenance program for underground waste tanks at the Hanford site.
The request follows news that six tanks at the site are leaking.
Wyden toured the site on Tuesday after Washington State Governor Jay Inslee announced last week that one tank was leaking.
Wyden is the new chairman of the Senate Energy and Natural Resources Committee.
As the search to replace current Energy Secretary Steven Chu begins, Wyden has said he'll seek a commitment during confirmation hearings for the next energy secretary that all radioactive waste at Hanford will be cleaned up.
