higher than consent limits. These
contaminants pose a minimal risk to the wider environment and will decrease with time by microbial
degradation or dilution. Recent site inspections reported that pasture strike is good in paddocks indicating
that residual contamination is having a negligible effect on pasture health.
On the basis that waste is no longer received, the soil sampling results, and recent observations, this report
recommends that the compliance monitoring programme may be reduced
or barriers
to good recycling behaviour. WasteMINZ is the largest representative
organisation comprised of members from across New Zealand working in the
resource recovery, waste minimisation, and contaminated land sectors.
Background and methodology
8. The key research questions were:
a) What are the public’s attitudes towards recycling? Do they have
understanding and belief in the system?
b) What level of knowledge do they have about what can be recycled and
how
and their significance for the environment in the Lower Waiwhakaiho area as a whole.

The Resource Management Act 1991 and monitoring
The RMA regulates 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
2023-2024 monitoring year.

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-
tested in July 2022.
Because the discharge of stormwater to the Herekawe Stream with even trace amounts of
herbicides is not permitted, Corteva elected to irrigate the affected ponds to the large
grassed areas of the site. This is permitted under Rule 29 of the Regional Freshwater Plan
(RFP) which provides for the discharge of contaminants from industrial and trade premises

Turangi Production Station showed that levels of nitrogen oxides were
below levels of concern at the time of sampling. No offensive or objectionable odours were detected
beyond the boundary during inspections.
For reference, in the 2022-2023 year, consent holders were found to achieve a high level of environmental
performance and compliance for 878 (87%) of a total of 1007 consents monitored through the Taranaki
tailored monitoring programmes, while for another 96 (10%) of the consents a good
The ambient air quality monitoring at the site showed that
concentration of nitrogen oxide during the survey was less than the relevant human health-based criteria at
the time of sampling. No significant odour or dust was observed during inspections and there were no air
quality-related complaints received.
During the site inspection on 31 May 2023 it was noted that hydrocarbon contaminated stormwater from
bunds had been discharged prior to the inspection. It is considered unlikely that
were measurable changes in some parameters, most of
these would have resulted in only minor transient effects at most. In terms of guidelines, there was no
exceedances of guidelines for pH, ammoniacal nitrogen, or biochemical oxygen demand. Dissolved copper
and zinc concentrations at the downstream site were found to be above the USEPA acute guidelines and
were the highest measured historically.
Overall, most consented discharges in the Waitaha catchment achieved a good level of
monitoring sites though annual programmes;
• the resource consents held by STDC for the closed landfills in their district;
• the nature of the monitoring programme in place for the period under review; and
• Each of the closed landfills is then discussed in a separate section (Sections 2 to 8).
In each subsection 1 (e.g. Section 2.1) there is a general description of the landfilled site and its discharges,
an aerial photograph or map showing the location of the former landfill, and an outline
