• R2/2708-3.1 Clark Peters Farms Limited – dairy effluent discharge.
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
August 2023 and 20 June 2024, at
the site during the monitoring period to assess compliance with resource consent conditions.
The site was empty and no activity was occurring during either inspection. The site was clean and tidy. Re-
grassing had been undertaken place to aid in better absorption for storm water. Despite heavy rainfall
preceding the August inspection, the site appeared to be containing storm water generated within it.

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
moderate temperatures and regular rainfall, but when the rainfall is heavy it can
cause flooding and landslips. In periods of low rainfall, the region can experience droughts. In some parts
of the region, and at certain times of the year, storms and tornadoes are a reasonably frequent occurrence.
Coastal erosion
Coastal erosion is the retreat of the shoreline caused by water currents, waves, and wind. It is a natural
process that can be influenced by human activity. The Taranaki coastline

rainfall prior to the inspection. No odour, foam or sheen was noted. The Mangatete weir appeared to be in
sound order as it had recently been repaired. The stream flowed freely over the structure. The flow was
moderate in height. A good level of residual flow was maintained over the fish pass. A small rock partially
blocked the structure. This should be removed if practicable as it may act as an obstruction which initiates
the accumulation of material at the fish pass. The rate
devices outlet structures.
