be determined if the results originated from the activities at the consent holder’s site or from the
neighbouring properties. The guideline reflects a deposition rate that may cause complaints in a residential
area.
In the 2016-2017 year there were no unauthorised incidents related to discharges from any consent holders
in the Lower Waiwhakaiho area.
During the year, Downer EDI Works Ltd demonstrated a high level of environmental and administrative
performance with their resource
exceeded six of the 12 samples
collected, while Downer EDI exceeded one sample from 10. The highest result during the year
under review was obtained by one of the Fitzroy Engineering Group Ltd gauges, which was
more than twice the guideline rate. The guideline reflects a deposition rate that may cause
complaints in a residential area.
In the 2015-2016 year there were no unauthorised incidents related to discharges from any
consent holders in the Lower Waiwhakaiho area.
During the year,
mornings the two week rain forecast is received from ‘WeatherWatch’, a
professional weather forecasting business.

9.4 The Uruti Site operator records the level in the irrigation pond Monday morning.
9.5 The Site Manager plans the weeks irrigation based on the irrigation pond level, the rain
forecast, and the application rate (rates are attached see Irrigation Areas/Rates). This
information is posted on the

development of the region’s resources.
1.1.4 Evaluation of environmental and administrative performance
Besides discussing the various details of the performance and extent of compliance by
the consent holder during the period under review, this report also assigns a rating as
to the Company’s environmental and administrative performance.
Environmental performance is concerned with actual or likely effects on the receiving
environment

The monitoring indicated the following:
The discharge of cooling water recorded an increasing ammonia concentration throughout the monitoring
period, though the impact to the Inaha stream was minimal. The thermal effect of the plant discharges were
within the thermal limits for the duration of the monitoring year. The abstraction of surface water and
groundwater was undertaken within compliance standards for the duration of the year. The dilution rate for
the surface water
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
trophic level. Updated trend analysis, for the period 1990-2018, reconfirmed the rate of increase in trophic
