Company notified the Council that a damaged irrigation
line had been discovered and that there was the potential that the resource consent conditions could be
breached. The damaged line was repaired without any discharges to surface water occurring.
Particulate deposition from air emissions was, in general, similar to the previous monitoring periods. At the
monitoring site east of the taker bay the lactose deposition rate was found to be almost four times the
guideline value and was the

expectations remain high.
Strong financial position
The Council finished the 2015/2016 year with a surplus of
$963,000 (total comprehensive income). Expenditure was
$373,000 over budget, in large part due to the Council
providing unbudgeted emergency funding to assist those in
need following the severe winter storm damage. Overall it
was a good result, noting that general rates increases have
been at or below the rate of inflation for the past few years.

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
report entitled Aggradation in rivers and streams
right should be granted and no general authorisation
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
in
productivity, continued to be within the category of mesotrophic to possibly
mildly eutrophic (mildly nutrient enriched). However, taking into account the influence of suspended
sediment in this reservoir, and the moderately low chlorophyll levels, the classification is more appropriately
mesotrophic. Previous trending of these water quality data over time found a very slow rate of increase in
trophic level. Updated trend analysis, for the period 1990-2018, reconfirmed the rate of increase in trophic
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.
