Inspection was carried out during wet weather following a period of rain throughout the
catchment. The influent screen was operating and wastes were fully contained. The main pond was dark
green/brown with a turbid appearance. A mild odour was noted downwind. Wildlife was numerous, with
over 450 mallard, paradise and teal ducks, Canadian geese and black swans.
Both wetland pond levels were normal. These were dark green/brown in colour and slightly turbid. No
ponding was noted in the vicinity of

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

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

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

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
inspection it was noted that the pedestrian entrances to the shed now had a protected
doorway porch to prevent wind and rain from entering the shed.
During each inspection a sample of the stream was obtained. The samples were clean and clear with no
sheen or odour, iron oxide is naturally present in the stream. There was no discharge from the stormwater
system to sample during any of the inspections.
At the time of each inspection the Company were operating in compliance with their resource
