time of the inspection with 6.5 mm of rain falling over the previous 48 hours.
Monk Rd Site:
The discharged wood waste appeared to be very clean and free of unacceptable wastes.
The new pond pipe had been connected to the existing pipe that led down to the
culvert under Monk Rd. Due to low flow conditions the culvert at Monk Road was only
discharging undiluted contaminated spring water (i.e. no freshwater flow was
occurring from
was potentially leaking, staff advised that this would be investigated in summer.
Ngatoro G: the ring drain had been redefined and metal placed alongside it to help filter sediment.
Kaimiro Production Station and Ngatoro-A: Heavy, persistent rain and strong winds had proceeded the
inspection and it was noted that the stormwater system on both sites was working well. All stormwater was
being collected and directed for treatment prior to discharge from the site. The sites were tidy and
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.

2.1 Inspections
27 August 2012
A site visit was made to conduct a compliance monitoring inspection and to take
groundwater samples. The weather was fine with 12 mm rain over the previous 24
hours.
Large areas of the crown of cap had been sown with grass. The re-grassed area had
been fenced off from stock. There were some areas of ponding around the stock
troughs and on the

trap, near the Firewater Pond. The carpark area project was on-going and a digger was working by burial pit.
The entrance to the old dairy factory on Old Normanby Road had traces of left over burial pit product in
front of the entrance. TBP staff were advised that this needed attention, as it was forming a crust and heavy
rain would likely cause it to discharge to the drain. A discussion was had about the importance of having
underground drain plans and these were again

in the skimmer pit under hot, sunny and
dry conditions, rather than any chemical source. The water level in the pit was very
low at the time of inspection. It was considered by Council officers that should
enough rain fall to cause a discharge, the pH would fall to well within consent limits
prior to any discharge occurring. No remedial action was required by the Council.
Also on 14 November 2012, a sample taken from the skimmer pit showed an elevated
suspended solids concentration. It
