From 5 November 2013 to 3 April 2014 a total of 13 samples were collected at each site
for the purpose of state of the environment monitoring (SEM). Whenever possible, no
SEM sampling was undertaken within three days following significant river freshes.
However, occasionally sampling was affected by localized rainfall and elevated river
flows. An additional seven samples were taken at five of the beaches (Onaero, Fitzroy,
Ngamotu, Oakura and Opunake) regardless of weather conditions for the
STDC landfills consent monitoring report - Taranaki Regional Council.
diversion of wastes to the Hawera WWTP in the 2010-2011 period, discharges from the Eltham
WWTP now occur only as a result of high rainfall events that exceed the storage capacity of the primary and
holding ponds, and the pumping capacity of the reticulated system to Hawera.
Analysis of the primary pond effluent was not required during the monitoring period, although the
condition of the pond and any associated odour continues to be monitored during routine inspections.

Any rainfall runoff and leachate that is generated, drains into a series of ponds for treatment referred to as
the pond treatment system (PTS). Between each pond is a baffle that skims off any floating hydrocarbons as
the leachate passes through. These ponds also treat the leachate and stormwater from pad 1 where

There were isolated showers with a light north westerly wind during the inspection. Rainfall of 60 mm had
been measured in the week prior at the Brooklands Zoo station, nearly all of which had occurred in the
preceding two days. SV8000 had recently been drained to accept stormwater from the hazardous
substances area. The water level in SV9100 was at 110

afforestation plan for the entire parcel attached to Mr Gibson’s evidence.

site office and about 100 m downstream of SH3/Mokau Road.

to ensure clean water running off the hills in rainfall events is diverted
around the active site areas.
