dominated by Papa mudstones which are easily eroded and can contribute to poor water
clarity in the water ways.

The Haehanga Stream is an entrenched meandering stream below the site, but adjacent the
composting facility the stream has been modified and channelized to provide drainage away
from the composting activities. The stream was

The site was inspected during a rainfall event and south westerly wind conditions.
A reasonable quantity of green waste material was found to be present at the time of
inspection. It was observed that the lower western area was nearly full and green waste
material had been dumped towards the river mouth section.
It appeared that contractors were regularly removing material from the drop off areas
of the site that would not be
environmental risks to staff and contractors
body_Text Train staff in Best Management Practice to reduce risk
body_Text Separate ie uncontaminated stormwater from flowing across potentially contaminated areas
body_Text Isolate ie contaminated areas using shut-off valves
body_Text Secure eg keep hazardous liquids or materials secure from tampering or spills
body_Text Clean eg keep outside working areas clean and tidy to prevent rainfall carrying contaminants off site, or clean vehicle
systems.
The treatment pond to the east of SH45 received stormwater and groundwater from
the quarry. Treated water was either discharged to the Waingongoro River, or
pumped to an adjacent dairy farm for pasture irrigation purposes.
The treatment pond to the west of SH45 received quarry washwater which was
recycled through the plant. An emergency overflow pipe installed in this pond
discharged to the river during very high rainfall events.

and May 2016 (370 g/m3) surveys (Table 2). The exact cause of this result could not be
identified but was likely due to rainfall and/or activities in the headwaters of the
stream.
