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.

contaminated
stormwater from three main processing areas. These are the greenwaste pad (Pad 1), the paunch pad (pad
2) and drilling waste pad (pad 3).
Pad 3, holds drilling muds, fluids and cuttings which are mixed with sawdust and/or other organic material
such as poultry waste. This is then composted in one very large pile which is turned to stimulate the
composting process in the initial phase.
Any rainfall runoff and leachate that is generated, drains into a series of ponds for treatment

Discharges to the Kahouri Stream
The stormwater pond was discharged on several occasions to the Kahouri Stream during the 2023/24
monitoring period. These discharges occurred during high rainfall events. During normal rainfall all
stormwater from both sites is collected and used within the process. Stormwater monitoring is undertaken
by the Company, including constituents and volume.
A variation for this consent was granted on 1 February 2024 to incorporate all

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

The maximum rainfall (43 mm/hr) used in
the application by Remediation (NZ) may be
a bit light.
This has been reviewed by the applicant in
their application.
The site needed to be tidied up generally.

Management plans and improved detail in
