Production Station had caused adverse effects on the water quality of the Kapuni Stream.
There were no adverse effects on the environment resulting from the exercise of the air discharge consents.
The ambient air quality monitoring at the site showed that levels of carbon monoxide, combustible gases,
PM10 particulates, and nitrogen oxides were all below levels of concern at the time of sampling. No offensive
or objectionable odours were

1.1.3 The Resource Management Act 1991 and monitoring
The RMA primarily addresses environmental ‘effects’ which are defined as positive or adverse, temporary or
permanent, past, present or future, or cumulative. Effects may arise in relation to:
a. the neighbourhood or the wider community around an activity, and may include cultural and social-
economic effects;
b. physical effects on the locality, including landscape, amenity and visual effects;
c. ecosystems, including effects
the
conditions of the applicable resource consents. There is no evidence of any issues with any injection well
currently in use, or the ability of the receiving formations to accept injected fluids. The results of
groundwater quality monitoring undertaken show no adverse effects of the activity on local groundwater
resources. Inspections undertaken during the monitoring year found sites being operated in a professional
manner and there were no unauthorised incidents in relation to any of the
environmental ‘effects’ which are defined as positive or adverse, temporary or
permanent, past, present or future, or cumulative. Effects may arise in relation to:
a. the neighbourhood or the wider community around an activity, and may include cultural and social-
economic effects;
b. physical effects on the locality, including landscape, amenity and visual effects;
c. ecosystems, including effects on plants, animals, or habitats, whether aquatic or terrestrial;
d. natural and physical resources

results have shown that zinc concentrations have generally continued to decline over time. Sampling
undertaken in the current period found zinc concentrations were within the resource consent condition
limits and that there was no likely effect on the receiving environment downstream of the site.
In the reported period, no effects from the emissions to air from the galvanising site were detected at or
beyond the boundary of the site.

The existing residual flow regime supports a diverse native fish community, with
inanga, redfin bullies, longfin eels and torrentfish all present within the residual
river reach. Brown trout are also present throughout, and densities of juvenile trout
and redfin bullies in the residual reach are similar to or higher than that elsewhere
in the river. In addition to these species, banded and shortjaw
Mangamahoe, and small areas around key HEPs infrastructure. Trustpower
does not own or manage other land within the wider catchment.
