evident on the site and in some places within the ring drains. The majority of
ring drains were vegetated with grasses that helped with controlling and treating sediment laden
stormwater. Other sediment controls were in place within the ring drains such as rock weirs and silt fences.
Hydrocarbon sheens were not observed within the skimmer pits or in puddles on any of the sites. The
skimmer pits were all in good order with goose neck pipes functioning as required. Following heavy rainfall

measuring the water level, at a minimum of 15 minute intervals, in the race at the
locations specified in condition 2, and shall make records of such measurements

boreholes on site indicated a relatively shallow water table. Test bores were augured to 10 m both around
the waste holding pit area and to the south-western site boundary, revealing alternating layers of sand and
clays. Bore construction also revealed localised peat layers within some augured cores (approximately 4–8 m
below surface). Average annual rainfall for the site is 1,043 mm (taken from the nearby Patea monitoring

Origin Energy Ltd’s Kauri D wellsite is situated in the eastern corner of the site, and there is a small coastal
lake inland and to the northeast (up gradient) of the storage pit area. Both of these operational features are

site is maintained by an abstraction from the
Ngaere Stream. Overflow due to rainfall entering this pond is discharged to land and to the Ngaere Stream
to the north of the pond. Stormwater from the process areas is directed to a large separator system to the
north east of the site. The effluent from this separator is discharged to a small unnamed tributary to the east
which joins the Ngaere Stream approximately 40 metres above its confluence with the Patea River.

animals is the predominant land use in Taranaki. Associated
with that land use is the discharge of animal excreta onto land with associated faecal
microorganisms, which can end up in waterways through overland flow during rainfall
events. These microorganisms can affect human health and animal health if ingested and
impact the instream values of waterways.
In Taranaki, and in other parts of New Zealand, there has been significant investment in
recent times by the farming sector in adopting a
