EDITORIAL: Social agreement needed for disposing of Fukushima soil

The two main measures are to recycle some of it and to eventually dispose of all the soil outside of Fukushima Prefecture. However, no course for those measures has been laid down because of difficulties in finding a location to serve as a final disposal site. This is a grave issue that society as a whole must squarely face. Soil removed during decontamination work within Fukushima Prefecture has been accumulating at an interim storage facility near the nuclear plant so as not to interfere with reconstruction efforts in the prefecture. The equivalent volume of 11 Tokyo Domes has been collected. In order to obtain local understanding, the government has proposed moving that soil outside of Fukushima for final disposal by 2045. The Fukushima governor accepted that proposal, but said it was an 'agonizing decision.' Many blocs in the Diet supported a legal revision that clearly stated it was the central government's responsibility to dispose of the soil outside of Fukushima. There is major significance to the promise made to disaster-stricken areas that were forced to shoulder serious environmental pollution and the bitterness of losing one's hometown. Because there were doubts about whether that goal could be realized, it is also a fact that politicians made a decision before thorough discussion was conducted. With only 20 years before the deadline for final disposal, the most pressing issue will be recycling the soil so the volume for final disposal is reduced. The plan is to use about three-fourths of the total volume with radiation concentration levels under 8,000 becquerels per kilogram of soil in public works projects in various parts of Japan. In the recently decided basic policy, one measure included was using the soil in shrubbery planted within the grounds of the prime minister's office as a sign the central government was taking the lead in the matter. To ensure sufficient safety, the government has said the radiation exposure of workers handling the soil would be kept under international standards and that measures would be taken to prevent the soil from becoming airborne or spilling out from the work site. But understanding will not deepen if only scientific safety is emphasized. The Environment Ministry's plan for experimental use of the soil in the Tokyo metropolitan area never got off the ground because of opposition from local residents. When the government recently sought out views about the recycling soil standard, many concerns and doubts were submitted. There was a sharp difference of opinion regarding the radiation risk from the nuclear plant accident in relation to farm products and the release of treated water into the ocean. Rather than imposing its views, the government has the responsibility of making every effort to achieve social agreement by removing concerns through civil dialogue with local governments and citizens. Now is also the time to enter into serious discussions about final disposal that will come after recycling. There are many issues to discuss, such as the cost and burden, including recycling of the soil, and what plans the government has for the areas around the nuclear plant once final disposal is completed. The handling of the removed soil is an especially difficult matter for the processing of the nuclear accident. According to an Environment Ministry study, only one in four respondents outside of Fukushima Prefecture know about the policy of final disposal outside of that prefecture. That is much lower than the slightly more than half of the Fukushima Prefecture respondents who are aware of that policy. The accident of 14 years ago occurred while Japanese society continued to use nuclear power under a 'safety myth.' The electricity generated at the Fukushima No. 1 nuclear plant was mainly used in the Tokyo metropolitan area. There is a need for deep and careful consideration about how to achieve a resolution to the issue by having the entire nation tackle the task of dealing with the aftereffects. --The Asahi Shimbun, June 4

Local pushback halted plans to reuse soil from Fukushima
Local residents near Shinjuku Gyoen National Garden in Tokyo opposed a government plan to reuse soil from Fukushima decontamination efforts in the park. (Akira Hatano) The government's first attempt to reuse mildly radioactive soil from Fukushima Prefecture as landfill in public works projects around Japan has been scrapped due to local opposition. Protests from local communities apparently led the Environment Ministry to scuttle the pilot project in March of last year. The 540-million-yen ($3.8 million) project would have used a few truckloads of the soil as landfill for flowerbeds and lawns in Tokyo's Shinjuku Gyoen National Garden; the National Institute for Environmental Studies in Tsukuba, Ibaraki Prefecture; and locations in Tokorozawa, Saitama Prefecture. Safety concerns persisted, despite plans to use the soil as underfill beneath the topsoil layer. Following the 2011 triple meltdown at the Fukushima No. 1 nuclear power plant, topsoil was scraped off from areas across Fukushima Prefecture to lower radiation levels. The removed dirt has since been stored in an interim facility near the plant. The accumulation totals 14 million cubic meters—enough to fill 11 Tokyo Domes. Under a law enacted for the post-disaster cleanup effort, the soil must be disposed of outside Fukushima Prefecture by 2045. To reduce the volume of dirt requiring disposal, the government plans to repurpose the least contaminated soil—considered safe in terms of radioactivity—for civic projects. The goal is to shrink the amount in temporary storage to less than one-quarter of its current volume. However, the failure of the recent pilot project highlights the challenges of gaining local support for these plans. Amid the opposition, the ministry extended its contract with private contractors twice before eventually terminating it. During that period, the ministry conducted safety tests at the interim storage facility to assess whether the soil could be transported safely without dispersal, and how to respond in the event of spillage caused by traffic accidents. Ultimately, the ministry paid 210 million yen from the original contract to the contractors for this and other related work. Despite the challenges, the ministry has expressed its intention to pursue its goal, stating that the termination of this particular contract does not mean the end of the broader plan.
