vegetation growth is primarily a
mixture of pasture and dune grasses. Test pitting and the logging of boreholes on site indicated a relatively
shallow water table. Test bores were augured to 10 m in the pit area, revealing extensive compacted, low
permeable clays underlying coastal dune sands. Pit construction revealed mostly tightly packed sand at the
pit bases (approximately 4-5 m below surface). Average annual rainfall for the site is 1,023 mm (taken from
the nearby ‘Duffy’ monitoring station).

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.

THE PEOPLE
Figures from the 2013 census show the total
severe coastal
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
