demonstrated good compliance with rise and recession rate restrictions for the lower Pātea River. The
Company provided adequate residual flows within the Pātea River at all times.
The Company continues to have issues with the timely provision of reports required by consents, likely in
part due to the complex and significant monitoring and reporting requirements. However, with ongoing
liaison by the Council during the year under review there was an improvement by the Company and all draft

For reference, in the 2022-2023 year, consent holders were found to achieve a high level of environmental
performance and compliance for 878 (87%) of a total of 1007 consents monitored through the Taranaki
tailored monitoring programmes, while for another 96 (10%) of the consents a good level of environmental
performance and compliance was achieved. A further 27 (3%) of consents monitored required improvement
in their performance, while the remaining one (<1%) achieved a rating of
consents for discharges from mobile abrasive
blasting around the region. All of the consents include a set of conditions which impose ‘bottom-line’
requirements that minimise adverse environmental effects from the discharges. Through the monitoring
programme the Council assess compliance with these conditions.
During the monitoring year the Council conducted two deposition gauge surveys to quantify the rate of
dust deposition beyond the site boundaries to determine if the dust caused
majority of takes being well managed and operating within relevant consent
conditions during the 2022-2023 period. The Council was required to enter three incidents in relation to
irrigation consents over this period, with all non-compliances deemed sufficiently minor not to warrant
further action from Council. The overall rate of non-compliance across all exercised consents was 7%, which
was the same as that seen during the 2021-2022 period.
During the 2022-2023 year, 93% of exercised
stream gaugings.
The monitoring indicated that the operation of the sluicing of the weir has improved, with flows not falling
below 151 L/s. There was one unauthorised incident recording non-compliance in respect to the water take
consent between 30 July and 5 August 2022. Due to a lightning strike which destroyed the scheme’s
electronics, OWSL were required to take water in manual operation mode, which resulted in a breach of
abstraction rate until OWSL could fine-tune the process. The

CCCWSL’s compliance with abstraction rate limits had declined slightly. The maximum abstraction limit was
exceeded for an extended period of time in order to maintain water supply for consumers on two occasions
when pipes had burst. This was recorded as a non-compliance in respect to the resource consent, and an

inspections, sixteen water
samples collected for physicochemical analysis and three biomonitoring surveys of receiving waters. In
addition, monthly emission results and abstraction records were provided to the Council by the Company
which were reviewed.
The monitoring showed that the Stratford Power Station continued to be well managed with negligible
environmental effects as a result of the exercise of their consents.
Surface water abstraction was compliant with daily rate and volume. Process
two consents to discharge effluent and stormwater into the Waingongoro River, two
consents to discharge effluent and solids to land, two consents for structures in watercourses, and one
consent to discharge emissions into the air at the plant site.
Monitoring is carried out by both the Company and the Council. The Company monitors water abstraction
rate, effluent flow rate and composition, receiving water quality, odour at the plant boundaries, effluent
loadings and soil and herbage for
