IDAHO FALLS, Idaho (AP) — Federal officials are planning to look into alternative treatment methods for the 900,000 gallons of liquid radioactive waste stored at an eastern Idaho facility.

The Post Register reports that the Integrated Waste Treatment Unit was supposed to have turned the liquid waste into solid form three years ago. But malfunctions at the facility have continued to stall progress.

Department of Energy deputy manager of the Idaho Cleanup Project, Jack Zimmerman, says a team will consider changes to the current plan to get things up and running, but that making the original plan a success remains the top priority.

Testing at the plant earlier this year uncovered some glitches. Officials say another round of testing is set to begin in coming days.
