stormwater sampling and release records and inspections of the discharge
point and receiving waters in the Herekawe Stream. Scheduled inspections were carried out on 16 August
2021, 4 February 2022, 11 March 2022 and 21 June 2022. Notes from these visits are summarised below.
16 August 2021
On site 10:45 to 11:15. Weather was fine with a light northwesterly wind. 15 mm of rainfall had been
recorded over the previous week at the Brooklands Zoo station. Stormwater ponds were sampled for

e) Maintenance, monitoring and reporting procedures;
f) Rainfall response and contingency measures including procedures to minimise adverse effects in
the event of extreme rainfall events and/or the failure of any key erosion and sediment control
structures;
g) Procedures and timing for review and/or amendment to the erosion and sediment control
measures listed in the ESCP; and,
h) Identification and contact details of personnel responsible for

downstream of the dam, and allows for a lower minimum flow when less than normal
rainfall reduces inflows.
Conditions 9 to 12 define the minimum and maximum allowable lake levels for winter
and summer periods, specify the required spillway gate settings during a high lake
level, and allows for some flexibility in lake levels to allow for a short term electricity
shortage. When such a shortage occurs, the consent holder is required to notify

data were sorted into arrays for each individual year, and then ranked from the highest to
lowest values. After discarding the highest 5 (1) percent of the ranked values for each year
the next highest values for each year are the 95th (99th) percentiles
In this report the 95th (99th) percentiles of daily maximum gust speed will be called the
‘extreme intensity’. The frequency of daily maximum gust speed exceeding the 1972-2006
mean 95th percentile rainfall values will be called the
discharge from the work area to the environment;

e) Maintenance, monitoring and reporting procedures;
f) Rainfall response and contingency measures including procedures to minimise adverse effects in
the event of extreme rainfall events and/or the failure of any key erosion and sediment control
structures;
g) Procedures and timing
note that Council expects that all consents issued will require an exclusive
discharge to land and full storage after 1 December 2022. This means that any
consented discharge expiring in 2022 or later must discharge to land.
Dual discharges may be allowed if the farm is in a high rainfall area and provision of
adequate storage is impractical. This option needs to be discussed with Council Staff.

4.10. Has the discharge point
discharge of stormwater and
wastewater onto and into land and into an unnamed tributary of the Kahouri Stream.
During the monitoring period, Fletcher Concrete and Infrastructure Ltd (Fletcher Concrete) demonstrated
a good level of environmental performance and high level of administrative performance.
There was a breach of consent conditions identified from sampling undertaken during a heavy rainfall event.
Levels of total suspended solids exceeded those allowed for in condition 7.

Productive Land
Land is one of our most valuable assets, providing
recreational opportunities and giving us a sense of place
and connection to our local environment. Farming and
forestry provide dairy, meat, wool and timber products
that contribute significantly to the regional economy and
support communities.
The natural variations of climate, topography and soil shape
how land is used and managed across the region. Regular
rainfall and deep, fertile
