the
environment. Organochlorine pesticides and arsenic can leach
slowly down the soil profile and can contaminate groundwater.
The extent of leaching will depend on the soil type, with greater
leaching occurring in sandy soils. The amount of rainfall or
irrigation will also influence leaching of contaminants through
the soil. Leaching may mean that the highest concentrations
of contaminants are below the soil surface at some sites. Soil

compliance with consent defined conditions on the five occasions they were collected. It is noted that the
facility discharge to surface water only occurs during significant rainfall events.
Noticeable odour was observed on a few occasions during the quarterly compliance inspections. The facility
is allowed noticeable, not objectionable or offensive odour beyond the boundary of the site.

2015/2016 was completed during
2014/2015. Projects with clear benefit to Taranaki were identified
by Council staff and successfully advocated for: a review of a
national High Intensity Rainfall Design System (with benefits for
hydrology, river engineering and civil defence response), and
development of Discrete Water Quality Sampling Standards (SEM
and Policy/NPS-FW implementation benefits). The Envirolink

Inspection was carried out during an extended period of dry weather. Earthworks
were being undertaken on-site with works on both the access track and drilling pad
underway. No metal had yet been imported to the site, however it was anticipated
that metal would be brought onto site within the next week. The first culvert on the
access track was installed earlier in the day with earthworks continuing about the
access, bridge losses, silt deposition and stock and fence losses.
The focus of the strategy however was the establishment of a flood prediction and warning system to
provide warnings to the local community. An automated warning system was subsequently developed
and an additional telemetered rainfall site installed in the Ngutawera sub-catchment to assist with these
warnings.
In regard to river channel management, the Strategy recommended that arrangements be made in
