1.1.4 Evaluation of environmental and administrative performance
Besides discussing the various details of the performance and extent of compliance by STDC, this report also
assigns a rating as to STDC’s environmental and administrative performance during the period under review.
Environmental performance is concerned with actual or likely effects on the receiving environment from
Waiwhakaiho, were the two most popular
river sites across the survey. Meanwhile, lake sites such as Lake Rotokare, Rotorangi and Ratapiko remain
popular for particular activities, including boating, jet skiing and camping.
Access to water recreational sites across the region was deemed to be relatively good, with 87% of
questionnaire respondents saying they had been able to access the sites they wanted, and 85% rating
overall levels of access as being good or excellent. The main factor determining …
showed that all daily volume limits and instantaneous abstraction rates were complied with.
During the year, NPDC demonstrated a high level of environmental and administrative
performance with the resource consents.
For reference, in the 2015-2016 year, 71% of consent holders in Taranaki monitored through
tailored compliance monitoring programmes achieved a high level of environmental
performance and compliance with their consents, while another 24% demonstrated a good
level of

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 the Trust’s approach to
demonstrating consent compliance in site operations and management including the timely provision of
information to Council (such as contingency plans and water take data) in accordance
with State of the
Environment monitoring requirements. The 2012-2013 programme continued to incorporate
these changes. A later consultant’s report (in 2000) re-confirmed trends (using up-dated
methodology) that the lake was phosphorus limited and remained mesotrophic. Further
trend reporting for the period 1990-2006 was provided as a component of the consents
renewal process and suggested that while there has been a very slow rate of increase in
trophic level, the lake would be classified as
accordance with State of the
Environment monitoring requirements. The 2011-2012 programme continued to incorporate
these changes. A later consultant’s report (in 2000) re-confirmed trends (using up-dated
methodology) that the lake was phosphorus limited and remained mesotrophic. Further
trend reporting for the period 1990-2006 was provided as a component of the consents
renewal process and suggested that while there has been a very slow rate of increase in
trophic level, the lake would be
be determined if the results originated from the activities at the consent holder’s site or from the
neighbouring properties. The guideline reflects a deposition rate that may cause complaints in a residential
area.
In the 2016-2017 year there were no unauthorised incidents related to discharges from any consent holders
in the Lower Waiwhakaiho area.
During the year, Downer EDI Works Ltd demonstrated a high level of environmental and administrative
performance with their resource
