a peak of 15.192m. The estimated return period at Riminui was a 1-in- 37 year event.
However this was based only on stage, and not corrected for flow or changes within
the river system. The channel clearing works may have increased the rate of flow and
at the same time, normal continuous river bank erosion worked to slow it down.

The topography of the Waitotara catchment makes it extremely difficult if not
impossible to establish sites for river

Oil Services Limited. Water samples were collected for physicochemical analysis on selected
inspections.
During the period under review, Port Taranaki Limited obtained a ‘good’ rating for
environmental and administrative performance and compliance with the resource consents.
There was one incident in relation to port maintenance and one breach of stormwater
discharge limits which required further investigation. The environmental performance of Port
Taranaki
expressly allowed for by resource consent or a rule in a
regional plan, or it falls within some particular categories set out in Section 14.
The Council determined that the application to take groundwater fell within Rule 49
of the Regional Freshwater Plan for Taranaki (RFWP) as the rate and daily volume of
the groundwater abstraction might exceed that of the permitted activity (Rule 48).
Rule 49 provides for groundwater abstraction as a controlled activity, subject to two
conditions:
•
within twelve months; and
soon after planting, if only a knock-down pre-plant
herbicide was used. Further releasing may be
needed depending on the growth rate of the
plants. At least two years is usual; several years
longer if the species is slow-growing.
If possible, all weeds should be controlled before
reaching ten centimetres height, either by spraying
or handweeding. Where vegetation does become
rank, hand-grubbing or line-trimming should be
carried out prior.

1.1.4 Evaluation of environmental performance
Besides discussing the various details of the performance and extent of compliance by the consent holders,
this report also assigns a rating as to each Company’s environmental and administrative performance during
the period under review. The rating categories are high, good, improvement

Environmental performance is concerned with actual or likely effects on the receiving
environment from the activities during the monitoring year.
waters were typically disposed of by release into surface streams.
Today, approximately 95% of produced waters in the US are disposed of via underground
injection at an estimated volumetric flow rate on the order of 10 million m3/day (Otton and
Mercier, 2012).

Habitat loss (through land
clearance and drainage) has
historically been the main
pressure on biodiversity. While
the rate of land clearance and
drainage has declined in recent times, the
ongoing loss and modification of remnant
habitats remains an issue, particularly on
privately owned land in Taranaki. Even
small losses of habitat can now have a
disproportionate impact on remaining
biodiversity – not only in terms of remnant

Environmental performance is concerned with actual or likely effects on the

Administrative performance is concerned with the Company’s approach to
demonstrating consent compliance in site operations and management including the
timely provision of information to Council (such as contingency plans
