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

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
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

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
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
