This chapter deals with the latest in a long series of attempts to streamline or integrate various industrial pollution control systems—a regime that began by bringing together integrated pollution prevention and control and waste management licensing but which now extends to water and groundwater discharge permits and controls on radioactive substances. The environmental permitting regime provides a broad, largely procedural, framework within which the substantive provisions of various European Directives are implemented across a range of industrial installations and waste management facilities. As such, it introduces few general changes of substance, merely reflecting, as many integrative measures have done, structural and administrative changes, and a reordering of what was already there.
