About unreported case of report based on Soil Contamination Countermeasures Law in city ordering construction

　In November 2020, the Ministry of the Environment issued a warning regarding the implementation of the notification obligation under the Soil Contamination Countermeasures Act.
　In response to this, we conducted a survey on city ordering work, and found that there were 83 unreported cases in the past six years based on the Soil Contamination Countermeasures Law and the ordinance on the conservation of the Living Environment in Yokohama City.
　At the earth and sand export destination of each construction, the specified earth and sand certification etc. are performed appropriately.
　After confirming the construction contents of these works, no effect that would lead to health damage was confirmed.
