I want to know the procedures at the time of opening, operating, and closing the cleaning business.

The main procedures of environmental laws and regulations required before, during, and when the cleaning business is opened are posted to everyone in the cleaning business.
If you are using specific hazardous substances (Park Ren, etc.), please note that procedures will also take place for soil contamination measures.
Example during business: Record of use of specified hazardous substances (operators), sending records to landowners, etc. (from businesses to landowners) (for details, to businesses dealing with specified hazardous substances)
When closed: Notification of abolition (operator), obligation to report soil survey (land owner)

・I would like to know the procedures for abolishing factories and business sites. (Including the abolition of only some facilities in factories and business establishments.)
