incorporating
odour surveys and four surface water samples collected for physicochemical analysis.
The water samples from the unnamed tributary of the Waiongana Stream indicated that the Company were
in compliance with consent defined conditions on the four occasions they were collected. It is noted that the
stormwater facility discharge to surface water, only occurs during significant rainfall events.
The Company continues to be proactive in their response to objectionable odour
(NPS-FM) regarding water quantity and specifically the requirements to
set environmental flows and levels, and associated limits. The memorandum also provides information on the
current state of water allocation across Taranaki and details the technical work done to help support the
implementation of the NPS-FM requirements.
Overview of surface water quantity
Taranaki receives frequent and plentiful rainfall. The amount of rainfall is extremely variable however,
increases significantly from
forming a tributary of the much larger Mimitangiatua awa
catchment. It runs from south-east to north-west. Almost the entire valley formed by the Stream is owned
by the Company, and consists of steep eroded hillsides, multiple side gullies, and small river flats distributed
along its length. The area receives more rainfall than the northern Taranaki coastline to the south-west. Soils
are generally poor and highly erodible. Patches of bush and planted trees cover most of the hillsides, with

2.3 Mr B Pope, Compliance Manager, in response to the question regarding Clark Peters
Farms Limited, advised that every dairy effluent discharge application is assessed on a
case by case basis and there are a number of environmental factors that are looked at
including land area, land size, and rainfall in the area.
2.4 Mr K Holswich, Iwi Representative, noted that the reporting provided by officers in
relation to consent applications are appreciated, it is very useful for hapū
significant rainfall
events.
13. The Company continues to be proactive in their response to objectionable odour identification, with
areas of the main storage shed closed to prevent odour release. Mesh doors that were installed during
the 2020/21 period continue to prevent mass air movement from within the shed. The Company also
maintains shelter belts/vegetative environmental buffers (VEBs), as a passive odour mitigation
technique. These buffers continue to establish and mature.

Technical Memorandum | Draft Baseline State for Escherichia coli and Cyanobacteria (Planktonic) in Taranaki Rivers and Lakes
year at 40 popular primary contact sites, including a range of beaches, rivers and lakes around Taranaki. There
are 23 freshwater sites (i.e. rivers and lakes) included in the current CISH programme.
The monitoring results highlight the impact that rainfall has on recreational water quality. Escherichia coli
concentrations can be
