details of the performance and extent of compliance by the CCCWSL, this
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

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.

Chief Executive, upon request.
Advice Note:
It is acknowledged that there is potential for inaccurate flow records associated with
measuring the residual flow using water level data, given that a change in the rating curve
may result in there being less flow at the water level recorder than when the previous rating
was in use was established.
As such, in the event that the Taranaki Regional Council identifies (via its river gauging) that

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%
water take consent conditions to
determine your allowed rate of take. You need to know
your allowed rate of take to see if you are covered by
the regulations and the date by which you must comply.

There are around 20,000 consented water takes in New Zealand.
About three-quarters are for irrigation – most of the other
consents are for community water supplies and industry. About
one-third of all consented takes (and about one-third of the

1.0 INTRODUCTION
This report summarises earthquake occurrence and ground deformation in Taranaki for the
period 1 July 2018 to 30 June 2019. It compares the location and rate of earthquake
occurrence in the last year with recorded activity post-1994 and also examines the ground
deformation data. These are used in assessing the quiescent state of Taranaki volcano.
