seed and for seedling
growth, as the tiny seed has few internal reserves. Plantation managers and
planting contractors note that seedlings grow faster on warm north facing
slopes.
• Climate: Mean annual temperature and rainfall determine the speed of seedling
growth, but the seedlings can germinate and grow in an extremely wide range
of conditions. Both species have woody roots that make them drought tolerant.
• Frosts: Once established, both species can withstand hard frosts and snow.

and vegetation growth consists mostly of pasture. Test pitting and the logging of
boreholes on site indicated a relatively shallow water table. Test bores were augured to
10 m both around the wastes 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
disc measurements were also taken upstream and downstream of the discharge to assess compliance
with the requirements of consent 2039-4.1.
Stormwater sampling was undertaken by the Council, during the two sampling rounds. Sampling was not
undertaken during or immediately following any heavy rainfall periods when stormwater runoff would be at
its highest.
The results of surface water sampling undertaken by the Council are included in Table 5 and Table 6 and are
presented against results

Prior to the
Wellington property consents (7670-1, 7884-1) being exercised there were areas of
pine which have been subsequently removed and processed.
Average annual rainfall for the site is 1383mm (taken from nearby Motunui
monitoring station). There are no significant surface water bodies located in the
immediate vicinity of the areas that are landfarmed, other than small farm drains.
Previous land use at the Wellington section of the landfarm has been a mixture of

giving a free
available chlorine of <0.01 g/m3. The weir inlet screens were cleaned during the inspection and the inlet
chamber was emptied. The screens were being cleaned frequently and this was due to increase further with
an anticipated increase in rainfall over winter and spring. A significant amount of work has been proposed
to upgrade the water pipe that carries water from the river to the plant. This work is in the planning process
and will include a more accurate flow meter at the river. …
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).
processed, compressed and piped to end
users. The produced water is disposed of by deep well injection.
Stormwater from the production station is collected and discharged at three separate points. The water level
in the firewater pond in the north western corner of the 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
