procedure. Notifications to Council were expected throughout the entire process. All resource consent
conditions were compliant at the time of inspection.
11 May 2021
A site inspection was carried out in overcast weather with light wind conditions. Heavy rain had been noted
in days prior to the visit, and this had resulted in some ponding within the bunded areas, however there
were no visible hydrocarbons present. All major works to re-line the bunds had been completed, with only
was also some replacement of square kerbing with radial.
Mangaotaki Rockfall (2008)
Heavy rain triggered a large rock fall on 4th August 2008 at the Mangaotaki Bluffs. The large
rocks blocked SH3 for almost 48hrs and a route detour through local council roads was required
during this time.
Two stock truck effluent disposal facilities have been built along the route, one in each of the
regions – the Taranaki one at Ahititi on the northern
Ratapiko from the Manganui River through the Motukawa Race.
To allow the diversion of water from the Manganui River, a concrete weir was constructed across
the Manganui River downstream from Tariki Road. The weir is approximately 4 m high and was
constructed in 1927 (C. England pers. comm). The current consented take from the Manganui River
at the weir is 5.2 m3/s, with residual flows at the weir of 0.4 m3/s. However, when flow in the
Waitara River (at Bertrand Road gauge) falls below 5 m3/s, all of
14 of the Resource Management Act stipulates that no person may take, use,
dam or divert any water, unless the activity is expressly allowed for by a resource
consent or a rule in a regional plan, or it falls within some particular categories set
out in Section 14.

As Taranaki Ventures Limited was unable to estimate the rate or volume of the take,
and as such, might exceed the limits of the
Act). Rules 35 and 36 of the RFWP do not
include any matters of control that expressly allow for the consideration of matters such as those expressed in
the NPS-FM objective. Given that the Council can only consider policies that relate to the matters over which
the Council has reserved control through the plan itself, the Council is unable to take into account matters
that fall outside this scope.
In terms of the notification assessment and when deciding whether a person is an affected
sensor system, the Company can monitor the residual flows in the Manganui River, water levels in the
race and lake, and how much rain is falling locally. This has allowed the Company to manage race flows to
minimise flooding and has greatly improved the Company’s compliance with residual flow requirements.
Resource consents
The Company holds 13 resource consents, the details of which are summarised in the table below.
Summaries of the conditions attached to each permit are set out in Section
persistent rain and strong winds prior to the inspection and it was raining heavily at
the time of the inspection. The stormwater system was working well, with all stormwater being collected and
directed for treatment prior to discharge from the site. The site was tidy and processes appeared to be well
managed with no spills or stains evident on the ground. Operationally good practices were being adhered
to with drip trays and chemical bunding in use. The skimmer pits were full, free of hydrocarbon
source of the elevated hydrocarbons and
remove them, no further action was taken at this stage.

The sumps system was inspected and no accumulations of oil
was found. As a precaution the sumps were emptied by
vacuum truck. A total of 45 mm of rain was recorded on 17-
10-23 and it was possible that this may have swept residual oil
contamination through the system.
