This MPG explains what actions need to be taken if old permissions for mineral workings and minerals waste deposits are to continue to have effect. The permissions concerned are those granted in the 1940s under Interim Development Orders (IDOs) and have remained in force even though they were granted before July 1948.
The guidance is addressed to owners or tenants of land with an IDO permission, persons with an interest in the minerals in such land, and minerals operators of sites currently being worked under an IDO permission.
It contains key points for action which such persons should take if they wish to have the permission preserved.
