Port Taranaki. The Taranaki
region has a temperate climate with generally
abundant rainfall. The incised nature of ring plain
streams means that flooding is not a major problem.
However, occasional intense rainfall events can lead to
rapid rises in river levels and flooding in hill country
valleys and elsewhere.

erosion were being removed as they became exposed. There has been no leachate observed discharging
from the sand dune area or the stockpiled green waste during the period under review, or in previous years.
These 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
The limit of 460 gm/m3 soil, is (assuming a soil bulk density of
about 1) equivalent to a MAF soil Na reading of about 20. Thus, while some
elevated soil Na levels were recorded during the disposal process the current
levels (0-75 mm) are normal (Table 2). This is also apparent in the SAR levels.
The likely reason for this is that Na (and the same applies to chloride) are very
mobile and will readily leach out of soils, especially sandy soils with a good
rainfall and under irrigation, noting

During this inspection, no runoff was observed offsite or past bunded areas. There was some ponding of
water beneath pig pens, with recent heavy rainfall likely a contributing factor. The methane generator was
not running at time of inspection and the methane pit was half full with some water present atop cover.

Any rainfall runoff and leachate that is generated on pad 3, drains into a series of ponds for treatment
referred to as the pond treatment system (PTS). Between each pond is a baffle that skims off any floating
hydrocarbons as the leachate passes through. These ponds also treat the leachate and stormwater from pad
