despite the dry conditions and quite strong wind. There were no odours noted onsite. The truck
wash had recently been used and all washings were captured. The sand trap was cloudy in appearance, the
level was lower than the drain and this was not discharging. In general the site was tidy and no spills or
other issues were noted around the site.

It was raining with a light breeze at the time of the inspection. The cap was in good condition and was
showing no signs of slumping. There was some ponding present, but the inspection was during a rain event,
thus this would be expected. There was evidence of good stock rotation and

A winter Inspection was carried out during fine weather following a period of heavy rain throughout the
catchment. The influent screen was operating and wastes were fully contained. The main pond was
green/brown in colour with a slightly turbid appearance. Odour was noted as being ‘slightly noticeable’. In
excess of 250 Mallard ducks were present on the pond.
Both wetland pond levels were slightly high. These were green/brown in colour and slightly
however the bung was missing allowing rainwater and possibly contaminants to discharge onto the ground.
One solution would be to place an oliophillic mat below the pump to capture any hydrocarbon while
allowing rainwater to drain, this was discussed with staff at the time of the inspection. Also discussed was
the purposed and use of plastic matting under the rig. For some areas plastic matting is suitable, however
for others the matting needs to be used to capture solid/liquid that falls from the

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

Stream. The discharge had no significant visual effect downstream in the receiving waters. Samples were
collected of the discharge, upstream and two sites downstream.

The primary screen was operating and wastes were fully contained. The pond level had been lowered in the
primary lagoon to allow a survey to be carried out around the wave band perimeter (remedial works are
planned during the 22/23 summer). The pond was turbid and

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
