wastewater. These inspections provided for the operation, internal monitoring, and
supervision of the plant to be reviewed by the Council. An additional inspection was
required in relation to a heavy rainfall event and follow-up after remedial works and
another inspection in relation to issues with the Esk Road trade wastes facility.
1.4.4 Wastewater and receiving water quality sampling
The Taranaki Regional Council undertook sampling of wastewater quality and
receiving river water
contributing waterways drain off the high, steep, unstable slopes of
Mount Taranaki and are capable of transporting large amounts of coarse sediment as bed load, as
well as fine sediment (TRC, 2011). Additionally, the orographic influence of Mount Taranaki results in
high local rainfall and attracts high intensity rainfall events in the headwaters of rivers originating on
the Maunga. This means sediment transport rates, and the frequency of sediment transport events,
are likely to be relatively high in the
holiday periods. The season under review was the first in which the increased frequency
has been provided by the Council.
During the 2016-2017 summer season, median faecal indicator bacteria counts for the majority
of sites were elevated compared to previous years. The higher counts were likely influenced
by unusually heavy rainfall throughout the summer. Out of the 244 samples collected for both
SEM and for additional monitoring purposes, 91% were below the Alert level. Of the samples

this monitoring period were lake levels below the usable range, therefore, any inability to use the ramp was
a result of maintenance issues. Boat ramp usability is discussed later in this report. During large rainfall

extremely high rainfall and therefore when the valley is flooding

• Remember that waste solvents can be recycled
• Store all paints, thinners and other liquids under
cover to prevent rainfall washing out pollutants
• If liquids must be stored outside, keep lids and caps
on containers and use a secure area to avoid
vandalism
• Keep all areas exposed to rainfall clean, and keep all
wastes out of stormwater drains
• Dispose of all waste via the sewerage system or a
commercial waste contractor.

the Company, and consists of steep eroded hillsides, multiple side gullies, and small river flats distributed
along its length. The area receives more rainfall than the northern Taranaki coastline to the south-west. Soils
are generally poor and highly erodible. Patches of bush and planted trees cover most of the hillsides, with
grasses over the remainder and the flats.
1.3 Process description
The Company’s operations include composting, quarrying and vermiculture operations
produced water is disposed of by deep well injection.
Stormwater from the production station is collected and discharged at three separate points. The water level
in the firewater pond in the north western corner of the site is maintained by an abstraction from the
Ngaere Stream. Overflow due to rainfall entering this pond is discharged to land and to the Ngaere Stream
to the north of the pond. Stormwater from the process areas is directed to a large API separator system to
the north east of
