Ecological Values
Sustainability - Positive In good vegetative condition. Under appropriate management, the
forest fragments can remain resilient and continue to contribute to
the wider ecological context.
Representativeness - Low Cathie Native Bush is a good example of Rata, tawa, kamahi,
podocarp forest (MF7-2) and contains vegetation associated with
LENZ environment F5.3b. This type of forest is considered less
reduced and better protected in Taranaki due to extensive areas
falling under
infrastructure was present.
The areas where muds were historically applied were observed to have complete pasture cover across all
areas. The pasture was described as healthy. Due to recent heavy rain the paddock contained lots of ponded
water. The ponded water appeared free of hydrocarbons. The overland flow observed on the foreshore had
lots of iron oxide present and iron oxide was also prevalent at the face of the cliff.

Inspections
25 August 2017
This inspection was conducted in fine weather with a light northerly wind. The cap was very damp, with
minor ponding in multiple areas following heavy rain during the previous weeks. The most significant
ponding was on the eastern border of the cap, approximately 5 m2 in size, and up to 10 cm deep. The lack of
vegetation in this area indicated that the ponding had been occurring for some time. Widespread minor
vehicle and stock damage was noted on the cap and batters,
except
for the NGI000174 second post-fracturing survey. There was a substantial decrease in
taxa richness at the ‘control’ site between the first and second post-fracturing surveys
which would be unrelated to any wellsite discharges and probably due to a
combination of high flows and stream typology. There had been significant amounts of
rain prior to sampling and river flows had exceeded 50 x median base flow on three
separate occasions in the ten days prior to sampling. The ‘control’ site is
current MfE guideline value. Levels
of toluene and xylene are particularly low by comparison.
Number of NOx and BTEX monitoring sites falling into different air
quality categories. The Action BTEX concentrations were recorded at a
central New Plymouth petrol station.
Air quality in Taranaki
The Resource Management Act 1991 (RMA) requires
councils to have regional plans to address regional
resource management issues. The Regional Air Quality

Methanex currently holds a consent for a
flood control structure in the Waitara River.
Section 14 of the Resource Management Act stipulates that no person may take, use,
dam or divert any water, unless the activity is expressly allowed for by a resource
consent or a rule in a regional plan, or it falls within some particular categories set
out in Section 14. Methanex currently holds two abstraction consents for the Waitara
River.

at valuation. Donated assets are
recognised upon receipt of the asset if the asset has a useful life of 12 months or more, and the
current value of the asset is readily obtainable and significant. Significant donated assets for which
current values are not readily obtainable are not recognised. For an asset to be sold, the asset is
impaired if the market price for an equivalent asset falls below its carrying amount. For an asset to
