1. Introduction
1.1 Purpose
This document is entitled ‘Regional Stock Truck Effluent Disposal Strategy for
Taranaki’ (this Strategy). The purpose of this Strategy is to set out the strategic
and planning framework for avoiding or minimising stock truck effluent
discharges onto roads in the Taranaki region.

1.2 Compliance monitoring and the Resource Management Act
1991
The Resource Management Act 1991 (RMA) primarily addresses environmental 'effects'
which are defined as positive or adverse, temporary or permanent, past, present or
future, or cumulative. Effects may arise in relation to:
(a) the neighbourhood or the wider community around an
nine incidents which resulted in discharges from the
wider wastewater network to waterways. Five of these incidents were related to pipe blockages or
breakages, two were related to mechanical or technical failures and two were related to power outages. No
unauthorised discharges were caused by high rainfall events during the year under review. The number of
incidents has continued to decrease from recent years (40 incidents in the 2014-2015 year, 24 in 2015-2016,
20 in 2016-2017 and 16 in
the plant. Current effluent application is considerably lower than previous
application rates. However nitrate concentrations in the soil profile underneath the
irrigation areas and in the tributaries flowing through or adjacent to the site remain
elevated.
A narrow but concentrated plume of ammonia is present in the groundwater and extends
from a previous leak in an effluent storage basin. This basin has since been repaired. A
second more recent and more concentrated ammonia plume extends
in the 2014-2016 monitoring
period.

1.1.3 The Resource Management Act 1991 and monitoring
The Act primarily addresses environmental ‘effects’ which are defined as positive or
adverse, temporary or permanent, past, present or future, or cumulative. Effects may
arise in relation to:
(a) the neighbourhood or the wider community around a discharger, and may
include cultural and socio-economic effects;
(b) physical effects on the
tributary a result of the Company’s activities. Environmental performance by
Winstone Aggregates was high.
No incidents or complaints were reported in relation to operations carried out at the Winstone
Aggregate, Wiremu Road quarry.
For reference, in the 2012-2013 year, 35% of consent holders in Taranaki monitored through
tailored compliance monitoring programmes achieved a high level of environmental
performance and compliance with their consents, while another 59% demonstrated a good

contamination reduces water quality, and has the potential to have both chronic and acute
impacts on the stream biota, which either leads to fish emigration, or death. It is understood
that the lower stream catchment is earmarked for urban development, with some thought
being given to establishing a reserve and walkway, similar to that alongside the Mangati
Stream. While this has the potential to improve habitat conditions in the lower catchment, it is
