Monitoring coastal water quality. Coastal erosionOur coastal areas are constantly under pressure from the sea. The coastline can be naturally eroded by scouring at the floor of high cliffs, at the dunes or at the subtidal foreshore. It takes place mainly during strong winds, high waves, high tides and storm surge conditions which can all lead to coastal retreat and loss of land. Sand dunes — what are they and what do they do?A sand dune is an accumulation of sand formed by wind, waves and eroding

Executive summary
Lake Rotorangi was formed in May 1984 by the construction of an
substrate composition and grazer density influence periphyton growth.
Periphyton is measured by the concentration of chlorophyll-a per square metre (a pigment that plants use
for photosynthesis). Periphyton is also measured visually so that it can be compared to guidelines for
ecological health or aesthetic values. Weighted composite cover measures the combined cover of some of
the less desirable forms of periphyton, such as long filaments and thick mats. Monitoring is carried out

Executive summary
The South Taranaki District Council (STDC) operates a total of ten water treatment plants (WTPs) which
supply municipal water to the district’s towns and water to the rural communities.
This report for the period July 2022 to June 2023 describes the monitoring programme implemented by the
Taranaki Regional Council (the Council) to assess STDC’s environmental and consent compliance
performance during the period under review. The report also details the results of the monitoring
resource consent applications pursuant to the Resource
Management Act 1991.
Ensure adequate compliance monitoring of resource use consents and receive decisions on
enforcement actions in the event of non-compliance, pursuant to the Resource Management
Act 1991.
Consider and make decisions on monitoring and enforcement matters associated with plant
and animal pest management.
Other matters related to the above responsibilities.

2000’s. Nine sites were recently added to the programme and therefore did not have five years of data
available. For these sites partial/incomplete data were used to form a baseline. Additionally, two sites did not
have five years of data prior to 2017 so could not fulfil the requirement of sub-clause 1.4(c). For these two
sites, a more recent five year data range was the only option to form a baseline so still fulfilled sub-clause
1.4(a). In summary:
For MCI, 25 sites reflected
scenarios decreased by 21%. This is due to the greater irrigation area facilitating
additional removal of nitrogen as plant matter. A ‘best-case’ modelled scenario is presented in which a
change to current management practises has the potential to reduce the nitrogen leached (compared
to the current 2019 scenario) by an additional 64%.
Model sensitivity analysis shows that an increase in irrigation area, increase in production (in the form
of removal of hay bales) and decrease in compost
was surveyed for
environmental effects.
HWWTP monitoring
Physical and chemical properties of wastewater in the HWWTP were measured in order to ascertain plant
performance during the 2020-2021 monitoring period. The monitoring was undertaken by the Council and
STDC.
The Council collected samples from Ponds 1 and 2 on six occasions during the year. These samples were
analysed for temperature, dissolved oxygen (DO) and chlorophyll a. In order to satisfy Conditions 5 and 6 of
