Biomonitoring surveys
A biological survey was performed on two occasions on 16 February 2017 and 26 April 2017, in the Kurapete
Stream, to document recovery of the biological stream communities following the removal of a continuous
discharge to the Stream.

consent holders, site inspections, and data gathering, review and
assessment for compliance. It was a busy season for the Council’s hydrological unit, as the
weather conditions meant the demand for irrigation was high. All irrigation had commenced
by the middle of December.
Over the five month (summer irrigation) period, Mount Taranaki recorded between 71% and
77% of normal rainfall for which meant that rivers were running well below normal for the
entire period. The low stream flows

indicated that the Company were
in compliance with consent defined conditions on the four occasions they were collected. It is noted that the
stormwater facility discharge to surface water, only occurs during significant rainfall events.
The facility is allowed noticeable, but not objectionable or offensive odour beyond the boundary of the site.
In the past, noticeable odours have been noted during the loading and unloading exercises, when material
is agitated, or fresh from the supplier.
Environmental Plan scope covers all the farm accept the vermiculture and composting pads,
the wetlands and the treatment ponds. The range of geology and topography in the catchment
requires specific management practices and these are shown in the operating plans listed below.
5.0 Climate
The climate in the Uruti Valley is generally mild and temperate. Rainfall is high, even in the driest
months of the year, compared to other parts of the region (See Table). Rainfall is measured and
recorded

factors, combined with the sandy
substrate and low rainfall at the beach would be restricting the production of leachate from the green
waste. It is therefore considered that, so long as STDC continues to monitor for and remove exposed
unacceptable material from the coastline, the environmental effects from the activities at the site are likely
to be no more than minor.

the frequency of sample collection earlier in the period. Sampling commenced in
early November 2010 with three of the sampling surveys performed prior to January
2011. The majority of the surveys were performed over the latter half of the summer
period. Bathing water samples were normally taken between the hours of 0900 and
1800 hours (NZDST) with none collected within a three day period following
significant river fresh conditions. [NB: regional differences in rainfall patterns have
