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.

We hope everyone has been able to relax
and enjoy the wonderful summer
weather we have been having although
the rain that is falling this weekend is
very welcome from a gardening point
of view. Here in New Plymouth, albeit
the sunniest city in New Zealand, rain
fell on 4 days in January giving a total of
12.5ml. Yesterday alone we had 180ml,
twice the normal rainfall for February.

established environmental limits.
Environmental effects of exercise of consents
Potential environmental effects on the receiving environment at this site include contamination by
hydrocarbon spills and increased sediment during high rainfall events. These effects are considered to be a
low likelihood. At the time of the sampling on 21st August 2023 it was found that the exercise of the consent
was having no more than a minor effect on the tributary.

recorded at upstream site 2 (KHI000353) during both the December 2015 (150 g/m3)
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.

Historical and current results from the industrial discharge from the yellow novaflow
pipe (IND005014) samples are presented in Table 3. Due to a lack of flow

The 2015/2016 'Envirolink' projects are underway: a review of

development of Discrete Water Quality Sampling Standards.
MBIE approval now provided for 4 projects in 2016/2017: farm
scale soil
upstream 2 (0.724 g/m3). The reason why there was an increase in zinc concentration
for the December survey from site upstream 1 to site upstream 2 and a subsequent
decrease in zinc concentration from site upstream 1 to site upstream 2 during the May
survey is probably related to rainfall. The spring survey is a ‘dry run’ where no rainfall
can occur three days prior to sampling while the summer survey is a ‘wet run’ and
occurs during heavy rain.
The site upstream 1 had a low pH for the 9
