Environment protection licences may be issued for the following purposes--
(a) to authorise the carrying out of scheduled development work at any premises, as required under section 47,
(b) to authorise the carrying out of scheduled activities at any premises, as required under section 48,
(c) to authorise the carrying out of scheduled activities not related to premises, as required under section 49,
(d) to control the carrying out of non-scheduled activities for the purpose of regulating water pollution resulting from any such activity, as referred to in section 122.
Note--: Scheduled activities for which a licence is required are set out in Schedule 1. Scheduled development work for which a licence is required is defined in section 47 (being generally work on premises, at which scheduled activities are not carried on, that is designed to enable scheduled activities to be carried on at the premises). This Act permits (but does not require) a licence to be issued for a non-scheduled activity--compliance with the conditions of the licence provides a defence to the offence of polluting waters under section 120.
