This subsidy supports prefectural/municipal governments and mine-drainage treatment operators carrying out works that prevent pollution and hazards arising from closed or abandoned non-coal/non-lignite mines. METI (via the Chubu-Kinki Industrial Safety and Inspection Department's Kinki Branch for this listing) covers eligible mines located in Fukui, Shiga, Kyoto, Osaka, Hyogo, Nara and Wakayama, with the goal of correcting the cost-burden imbalance when the original obligor is insolvent or no longer exists. Eligible applicants are (1) local governments executing pollution-prevention or hazard-prevention construction for subject mines whose responsible party is insolvent or no longer exists, and (2) mine-drainage treatment operators (and the designated mine-pollution-prevention organisations / JOGMEC etc. that succeed them) for mines whose mining right has lapsed or whose extraction ceased long ago with no resumption prospect. Organisations covered by the anti-organised-crime pledge are excluded. Covered expenses include pollution-prevention works (slag/spoil removal and transport, dike construction or refurbishment, drainage channels and culverts, gallery sealing, drainage water collection/conveyance/treatment facilities, prevention of dispersal of residual hazardous substances, backfilling of open-pit traces), hazard-prevention works (sealing of gallery mouths, residual-wall trimming and anti-collapse facilities), mine drainage water treatment, and post-completion facility upkeep works. Main construction cost, ancillary works, surveys and tests, land and compensation, miscellaneous works expense and administrative expense are recognised line items. The subsidy rate is up to 3/4 of the eligible expense; minimum award is in principle JPY 1,000,000. No fixed per-case upper cap is stated in the ordinance — amounts are individually appraised within the annual budget. The application deadline is 31 July of the relevant fiscal year for pollution-prevention works and mine-drainage treatment, and 31 August for hazard-prevention works (urgent cases excepted). Use Form 1 (local governments) or Form 24 (drainage operators) with a construction plan and itemised cost statement, file to the competent Industrial Safety Supervision Department Director; standard processing period is 30 days; electronic filing via the subsidy system is permitted. Final report is due within 30 days of completion or by 10 April of the following fiscal year, whichever is earlier.
