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

It was found that the drain pipe for the contaminated spring water discharge had been
extended and it was noted that the downstream drain had recently been cleaned out.
The inspection at the sawmill site found that silt control sumps and stormwater
collection drains had recently been cleaned out. It was noted that heavy rainfall in the
past had caused excess stormwater runoff from the site to discharge to the
neighbouring railways site. The inspecting officer was informed that a ponding
loamy sand. Vegetation growth is primarily a mixture of pasture and dune
grasses. 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 1383 mm (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.

construction revealed
mostly coarse sand at the pit bases (approximately 3-4 m below surface).
Average annual rainfall for the site is 1043 mm (taken from the nearby Patea
monitoring stations). 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
was neat and tidy with all ring drains and bunds clear. The fire water pond
was clear and there was no stormwater discharge to the Kapuni Stream, and no effects
were noted of any previous discharge. A pilot flare only was in operation at the time of
the inspection.

An off-site inspection at the stormwater discharge point to the Kapuni Stream was
undertaken during significant rainfall to assess any possible effects to the river. The
discharge was observed to be minimal,
