Note: All consents issued will require an exclusive discharge to land and full storage after
1 December 2022. This means that any consented discharge expiring in 2022 or later
must discharge to land when the consent is renewed.
Dual discharges may be allowed if the farm is in a high rainfall area
August 2023 and 20 June 2024, at
the site during the monitoring period to assess compliance with resource consent conditions.
The site was empty and no activity was occurring during either inspection. The site was clean and tidy. Re-
grassing had been undertaken place to aid in better absorption for storm water. Despite heavy rainfall
preceding the August inspection, the site appeared to be containing storm water generated within it.

year under review some unacceptable material was dumped at the Pātea Beach green waste
discharge site, but it was removed promptly by STDC. There was no leachate observed discharging from the
sand dune area or the stockpiled green waste during the period under review, or in previous years. These
factors, combined with the sandy substrate and low rainfall at the beach should be restricting the
production of leachate from the green waste. It is therefore considered that, so long as STDC continues
showers at the time of the survey. Based on the Council’s rainfall data from
Brookland’s Zoo, rainfall intensity peaked at 1.5 mm/hour between 0900 and 1000. There had been
intermittent rainfall in the seven days leading up to the survey. With respect to the consent limits, there
were two non-compliant results. Total suspended solids (TSS) was 120 g/m3 in the sample from STW001089,
which discharges stormwater from the B log yard and the railway area, and pH (5.6) at STW001159, which

and then piled up on the remediation pad. Any rainfall runoff and leachate that is
generated, drains into a series of ponds for treatment. Between each pond is a baffle
that skims off any floating hydrocarbons as the leachate passes through. These ponds
also treat the leachate and stormwater from pad 1 where remediated drilling wastes are

stored and/or processed further. The treated liquid from the pond treatment system
currently monitored by TRC on a regular long-term basis. In addition, the Northern
Hill Country FMU is under-represented in the monitoring network with only one monitoring site.
At a catchment level, the monitoring sites generally over-represent catchments with:
mean annual temperature <12°C;
mean annual effective precipitation >1500mm;
50% of the cumulative rainfall volume fell between 400m and 1000m;
volcanic acidic dominant geology, and pastoral land cover.
nitrogen per hectare per year (KG/HA/YR), often called units of N.
This is the difference between the total units of nitrogen
brought onto the farm and the total units of nitrogen that
leave the farm as products.
A high amount of surplus nitrogen can indicate an inefficient
conversion of available nitrogen into milk protein.

jetties to the outlet grids had been constructed by the consent holder relatively recently
for cleaning and maintenance purposes.
The new outlet from the final pond was clear of debris on all of the inspection
occasions. The provision for influent splitting at the entrance to the ponds’ system had
been designed for use only under high (stormwater infiltration) flows. The influent
splitter is checked after heavy rainfall and on a regular weekly basis by the consent
holder’s contractor
