deposited sediment was not likely recorded.
In the instance of the non-compliant discharge sample, this event followed a period of
heavy rainfall with moderate flow in the Kurapete Stream. Relative to the period
surrounding the biomonitoring survey, the stream was likely less vulnerable to impacts
from the quarry at the time of this discharge. This is reflected in the results from the
receiving water samples, which were compliant. Furthermore, observations of the
Kurapete Stream noted that the
(approximately 3-4 m below surface).
Average annual rainfall for the site is 1,043 mm (taken from the nearby Patea
monitoring station). As with the other South Taranaki coastal sites, the Vanner site is
subject to strong winds predominantly from the N-NW at average speeds of 10-20
knots (taken from Hawera automated weather station).
The Mangaroa Stream runs through the northern extent of the site separating the
stockpiling facilities and some of the available spreading area from the main

The autumn samples were collected after heavy rainfall in the 2013-2014, 2014-2015 and 2015-2016 years
resulting in the ammoniacal nitrogen concentrations of the samples collected being elevated when compared
the 2009-2012 years. During the year under review, ammoniacal nitrogen concentration continued to be
elevated, (Figure 3), but to a slightly lesser extent due to the lower rainfall in the month preceding this

2.1.3.1 Stormwater monitoring by SENZL
SENZL monitors the combined stormwater discharge from the site, with sampling triggered by rainfall
events. Table 3 shows the results obtained during the 2016-2017 monitoring year. In all samples
hydrocarbons, pH, suspended solids and chloride levels were all below the limits set by consents 5997-1
