2.1.3.1 Stormwater monitoring by OMV
OMV monitors the combined stormwater discharge from the site, with sampling triggered by rainfall events.
Table 4 shows the results obtained during the 2019-2020 monitoring year. In all samples pH, hydrocarbons,

Taranaki region has a temperate climate with generally abundant rainfall. The incised nature
of ring plain streams means that flooding is not a major problem. However, occasional intense rainfall events can
lead to rapid rises in river levels and flooding in hill country valleys and elsewhere.

in discrete areas, such as near river mouths
and in close proximity to wastewater discharges. At river mouths, water quality can be
reduced as a result of contaminants from land use and development (e.g. farming,
earthworks, urban centres, industrial sites) entering waterways, particularly during or
following heavy rainfall events. Accidental discharges of largely untreated wastewater can
have temporary adverse effects on coastal water quality. Wastewater discharges from
large population
also undertaken by the Council, from a stormwater drain located directly above the
weir on the Waingongoro River, to ensure any stormwater discharged meets consent requirements.
Sampling was not undertaken during or immediately following any heavy rainfall periods when stormwater
runoff would be at its highest.
The results of surface water sampling undertaken by the Council are included in Table 4 and Table 5 and are
presented against results undertaken during the previous reporting period
