By eliminating sewage in the disposal site, we will remove pollution sources and control the leakage of sewage. In addition, wells are installed at groundwater contamination points to prevent the spread of contamination by pumping up and removing contaminated groundwater.

After installing earth retaining, etc. (deep foundation wall), the steep slope is shaped into a stable slope to prevent waste from collapsing outside the site. In addition, the soil is covered with the waste after shaping to prevent the scattering and outflow of waste.

The Business Waste Management Section strengthens the monitoring system in the event of abnormal weather or an earthquake, and checks local safety.

We will continue to pursue responsibility for executors who have left improper conditions for many years, including the collection of administrative substitute execution costs. In addition, we will continue to investigate whether or not there is any violation of laws and regulations, and will pursue responsibility if there is a violation.

A payment order and reminder were issued to the executor using the expenses required for the construction that had already been finalized as receivables, but the payment was delinquent. For this reason, we have seized construction heavy equipment left in the disposal site and property (deposits, real estate, etc.) owned by former officers and exchanged them through public auctions, etc., and collected about 7 million yen so far.

We conducted a survey of waste discharge companies and received proposals from 25 companies for voluntary removal of waste.
