Regulations on Handling of Excavated Soil Based on Embankment Regulation Laws and Future Prospects

Abstract

Improper disposal of contaminated soil, landfill and embankment caused by soil mixed with waste, and excavated soil (such as embankment collapse disasters) were being handled under the sediment ordinances of municipalities in the Kanto region and other areas where these problems were becoming apparent. However, since May 26, 2023, a new law enacted in response to the massive mudslide disaster in Shizuoka Prefectureʼs Atami City in July 2021 has made it necessary to adopt uniform standards nationwide. This paper summarizes the new laws and regulations, and provides the authorʼs personal opinion on how municipal ordinances can respond.
