monitoring by OMV
OMV monitors the combined stormwater discharge from the site, with sampling triggered by rainfall events.
Table 3 shows the results obtained during the 2021-2022 monitoring year. There was no discharge at the
time of scheduled sampling during April 2022. In all samples pH, hydrocarbons, and suspended solids levels
were all within/below the limits set by consents 5997-1, 6269-1 and 10933-1, and were indicative of a
consistently clean discharge. OMV initiated daily stormwater

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 separator system to the
north east of the site. The effluent from this separator is discharged to a small unnamed tributary to the east
which joins the Ngaere Stream approximately 40 metres above its confluence with the Patea River.

Average annual rainfall for the site is 1,383 mm (taken from nearby Motunui monitoring station). There are
no significant surface water bodies located in the immediate vicinity of the areas that are landfarmed, other
than small farm drains. Previous land use at the Wellington section of the landfarm has been a mixture of
agriculture and small scale forestry. Further inland

Average annual rainfall for the site is 1,043 mm (taken from the nearby Patea
monitoring station). As with the other South Taranaki coastal sites, the Vanner site is
subject to strong winds predominantly from the N-NW at average speeds of 10-20
knots (taken from Hawera automated weather station).
The Mangaroa Stream runs through the northern extent of the site separating the
stockpiling facilities and some of the available spreading area from the main spreading
area at the southern end of
marginal coastal land situated on reworked
dune fields. The predominant soil type has been identified as black loamy sand, and
vegetation growth is primarily a mixture of pasture and dune grasses. Average annual
rainfall for the site is 1,122 mm (taken from the nearby Glenn Road monitoring station).
Two significant surface water bodies run adjacent to the spreading areas. The Waimate
Stream flanks the north-western side of the main western site, whilst the Rawa Stream
runs adjacent to the
