especially in the South Island.
On favourable higher altitude sites, Douglas-fir
exhibits a significant growth advantage over other
species. A high proportion of the tree’s wood is
heartwood, which is non-durable in ground contact.
Consequently, it is most commonly used for
structural purposes in engineering and construction.
Siting
Douglas-fir grows well over most of the country in
areas which receive moderately high rainfall (1000 to
1500mm annually). Growth is generally best on moist,
access to the local stormwater either through direct
discharge or by being washed off the site by rainfall or
by poor forecourt cleaning practices.

The Taranaki Regional Council recommends the
following service station requirements as best
management practices. Check this information when
operating your service station and when establishing or
upgrading daily site operational procedures. If all of the
items on the list are fully addressed then the potential

been recorded over the previous week at the Brooklands Zoo monitoring station. Stormwater pond SV8000
contained 550 m3 of stormwater, while SV9000 held 125 m3. The ponds were very clean and no sheens or
odours were noted. Recommissioning of the incinerator had begun following refractory work and it was
anticipated that this would be operating again shortly. Resurfacing of the dangerous goods area was well
underway, a new sump had been installed and two of the

A scheduled inspection of the quarry site was undertaken by an inspecting officer. At the time of the
inspection there had been significant rainfall at the site. The site was found to be well bunded with all
surface water either kept on site or directed to the treatment system. Since the previous inspection
significant work had been undertaken to install three new settlement ponds on the lower level of the quarry.
These ponds appeared to be working well and along with
The eastern hill country is
a steeper part of the region, and the sedimentary soil

regional land transport systems pass through this zone.
There are over 530 named rivers in the Taranaki region
and most flow from Mt Taranaki with short, narrow
catchments with steep gradients and sometimes high
amounts of sediment. High rainfall and hilly topography
means the region’s rivers can rise very rapidly.

The site was inspected during a rainfall event and south westerly wind conditions.
A reasonable quantity of green waste material was found to be present at the time of
inspection. It was observed that the lower western area was nearly full and green waste
material had been dumped towards the river mouth section.
It appeared that contractors were regularly removing material from the drop off areas
of the site that would not be
