construction also revealed localised peat layers within some augured cores (approximately 4–8 m below
surface). Average annual rainfall for the site is 1,043 mm (taken from the nearby Patea monitoring station).

bases (approximately 4-5 m below surface). Average annual rainfall for the site is 1023
mm (taken from the nearby ‘Duffy’ monitoring station). As with the other South
Taranaki coastal sites, the Remediation site is subject to strong winds.

The site was neat and tidy. Ring drains and bunds were clear. The skimmer pits were
clear of debris following high winds in the weekend. The discharge was not causing
any visual impact in the receiving waters. No flaring was occurring.

The Taranaki region has a temperate climate with
generally abundant rainfall. The incised nature of
ring plain streams means that flooding is not a
major problem. However, occasional intense rainfall
events can lead to rapid rises in river levels and
flooding in hill country valleys and elsewhere.

Now all mixing and blending of material is undertaken in a dry, sealed, storage depot. There are two
discharges from the facility. One, a wastewater discharge, which is to land via land soakage, the other, a
stormwater discharge, is also to land. In extreme rainfall the Company may discharge to the unnamed
tributary of the Waiongana, a surface water monitoring site has been established to monitor such a
discharge.
There were zero

• Regular inspections of the interceptor pits occurred; and
• Maintenance and repairs were carried out if required.
Interceptor pits do not discharge directly to surface water, instead they discharge
onto and into land where the discharge usually soaks into the soil before reaching
any surface water. However, if high rainfall had resulted in the discharge reaching
the surface water, significant
