In FY2022.3, there were 4 cases of nonconformity: 2 cases of exceeding the sewage elimination standard due to excess pH, 1 case of scattering ofasbestos spraying material during demolition, and 1 case of removal and disposal under an industrial waste contract with a primary subcontractor as
the discharging company.
The government issued a letter of guidance and a letter of recommendation, etc. We submitted an improvement report to the government in responseto the guidance and recommendation letters. As efforts to prevent recurrence, measures were taken at the work site (construction office), e-learning
was conducted within the company, a procedure manual was prepared and disseminated, and a notice was issued.
Note that we strive to prevent conflicts for reoccurring by aptly responding to the complaints we receive and caring for the environment surrounding
our sitesp. 2
