review can be summarised by the following main points:
Surface soils across the site are dominated by semi-porous silty clay-loams, overlying more
impervious clay soils
Soils below 2000 mm have not been characterised
Chloride concentrations in the soil beneath the irrigation zone are highly elevated compared
to non-irrigated areas
The shallow groundwater table is in direct connection with semi-porous loamy silty-clay
Due to high rates of irrigation loading, shallow

cannot be directly translated to NOF bands.
Trend analysis was performed by applying a LOWESS fit (tension 0.4) to a time scatterplot
of the percentage cover of thick mats, and long filaments of periphyton for all sites and by
testing the significance of any trend using the Mann-Kendall test at the 5% level, followed by
Benjamini-Hochberg False Discovery Rate (FDR) analysis.

1.1.4 Evaluation of environmental and administrative performance
Besides discussing the various details of the performance and extent of compliance by Methanex, this report
also assigns them a rating for their environmental and administrative performance during the period under
review.

which was occurring at a rate greater than the natural rate of supply.
It has been ten years since the Taranaki Regional Council (the Council) adopted the Freshwater
Plan. The Freshwater Plan contains a suite of policies, objectives, and methods associated with
riverbed gravel extraction.
In 2011 the Council undertook a preliminary analysis of river aggradation1 in Taranaki. The

made in respect of the Hangatahua (Stony) River catchment where the effect of doing
so would be that the provisions of the Notice could not remain in force without change
or variation. The fourth provision of the Notice stated that the quantity and rate of flow
in the Hangatahua (Stony) River and its tributaries, and the quantity and level of natural
water in the ponds and tarns that form part of the protected waters, were to be retained

detrimental effects were found at the time of the November survey. At the time of the March
survey the results suggested poor preceding water quality that may be indicative of adverse effects
associated with the landfill leachate.
Air quality monitoring showed that there were no significant adverse effects in relation to suspended
particulates, dust deposition rates or odour beyond the site boundary.

Good, as although the performance against most consent conditions with respect to the
administrative compliance was high, issues around testing of the integrity of the water take
pipeline and meeting the requirements of the Resource Management (Measurement and Reporting
of Water Takes) Regulations 2010 are yet to be resolved. Methanex have been open and
participative in their communication with regard to their progress on these issues.
For reference, in the 2015-2016 year, 71%

report also assigns them a rating for their environmental and administrative performance during the period
under review.
Environmental performance is concerned with actual or likely effects on the receiving environment from the
activities during the monitoring year. Administrative performance is concerned with CCCWSL’s approach to
demonstrating consent compliance in site operations and management including the timely
