water bodies^
,
artificial watercourses*
and the
coastal marine area
^ is prevented
run-off from the surrounding catchment is prevented from entering the area.

Discharges^
of
untreated human effluent*
directly into surface
water^

Prohibited
Rule Guide:
The location of archaeological sites when defined by a single co-ordinate is unlikely to define the true extent of subsurface archaeological evidence. The 50 metre rule should apply from the outer perimeter of the site.
Some discharges in
rare habitats*
,
threatened habitats*
and
at-risk habitats*
are regulated by
Rules 13-8
and
13-9
. Discharges at other locations are regulated as follows:
Activities not covered by rules
- Discharges of sewage pursuant to ss15(1) RMA that are not covered by the rules above are a discretionary activity under
Rule 14-30
.
Activities that do not comply
- Discharges of
domestic wastewater*
pursuant to ss15(1) or 15(2A) RMA that do not comply with the permitted activity, controlled activity or restricted discretionary activity rules above, but which are not prohibited, are a discretionary activity under
Rule 14-30
.
