Japan’s environment ministry has lifted the radioactive designation it applied to a batch of waste after the 2011 Fukushima Daiichi nuclear accident.
About 200 kilograms of waste stored at a private facility in Yamagata Prefecture can now be disposed of as general waste.
People familiar with the matter say the radioactivity level of the waste was confirmed to be lower than the government-set level of 8,000 becquerels per kilogram.
The ministry said it sent a letter, dated January 13th, to notify the facility of its decision to lift the designation.
It is the first time the ministry has lifted the designation for waste kept by a private company in connection with the nuclear accident.
Last July, the ministry lifted the designation of radioactive waste stored in the city of Chiba, just outside Tokyo. It was the first case among municipalities storing radioactive waste from the Fukushima accident’s fallout.
Ministry officials say as of September 30th last year, there was about 179,000 tons of waste designated as radioactive across the country.
