should these sites be converted to pasture.
Indigenous forest
As previously noted, we have discontinued the practice of comparing indigenous sites to
target values as they can be highly variable in soil quality indicators and there is generally
little that can be done to manage indicators that are outside target values. Nevertheless,
we still encourage sampling of indigenous sites as they form a baseline for rate of change
in other land uses.
It is interesting to note that

14 The Consent Holder must keep records of the volume and location of all wastewater irrigated to land under this consent.
a) From a date no later than two months after this consents commencing, the consent holder must measure and record the
rate and volume of discharge from the Irrigation Pond at intervals not exceeding 1 minute to an accuracy of +5%;
b) The consent holder must provide the Chief Executive, Taranaki
Lake Rotorangi is due to be performed in
the 2020-2021 period.
Lake condition, in terms of lake productivity, continued to be within the category of mesotrophic to possibly
mildly eutrophic (mildly nutrient enriched). However, taking into account the influence of suspended
sediment in this reservoir, and the moderately low chlorophyll levels, the classification is more appropriately
mesotrophic. Previous trending of these water quality data over time found a very slow rate of increase in
Besides discussing the various details of the performance and extent of compliance by
the Company, this report also assigns them a rating for their environmental and
administrative performance during the period under review.
Environmental performance is concerned with actual or likely effects on the receiving
environment from the activities during the monitoring year. Administrative
performance is concerned with the Company’s approach to demonstrating consent
compliance in site operations and
implications of wastage. This was especially evident in the industrial sector, and several
local businesses affiliated to large companies with head offices overseas noted that
environmental management was built into their systems.
There are however, significant areas where awareness is not high or opportunities to recycle
are limited, and also anecdotal evidence of poor practice in some sectors.
This points to the need for educational programmes targeting areas where recycling rates (if

NPDC monitors both the incoming wastewater and the treated wastewater
discharged from the WWWTP, for both chemical and microbiological parameters,
and analyses for various parameters at both weekly and monthly intervals. The
volume of incoming wastewater is measured and recorded continuously. The
treated effluent discharged has continuous measurement of flow rate and pH.

2018-2019 regional NOx study were also presented in this report. The associated analysis
indicated that the neighbouring Kapuni Production station was rated in the ‘good’ category (National
Environmental Standards) for 1 hour averages.
These results, and all regional monitoring to date, have shown that Taranaki has very clean air, and on a
regional basis there are no significant pressures upon the quality of the air resource.
Further, site specific ambient air quality monitoring is proposed
