The site was inspected following reasonably heavy rainfall over the preceding 12 to 18 hours. All ring drains
and bunds were clear of contamination and the skimmer pits were operating in a satisfactory manner. There
were no adverse effects of discharge observed in the nearby tributary. Full drums of oil were securely
contained in a bund while empty drums were awaiting removal.
No flaring was occurring.

Fern Farms staff member, who was also surprised to see ponding in the sandy bottomed paddock. This was
discussed and it was noted that best practice
growing as mats on the rocks of a river bed
(benthic) or floating and drifting in lakes
(planktonic). During the summer months,
increased water temperature, reduced rainfall
and increased daylight hours provide ideal
conditions for cyanobacteria to grow, sometimes
resulting in algal blooms. When in bloom,
cyanobacteria can produce toxins that can pose a
risk to the health of people and animals entering
the water.
Sites monitored for benthic cyanobacteria were
suitable for recreational
leachate generation from additional
stormwater infiltration. Figure 3 shows ammoniacal nitrogen results since 2005. Some of the higher results
(e.g. 2015), can be attributed to heavy rainfall preceding sampling.

shallow water table. Test bores were augured to 10 m in the pit area, revealing extensive compacted, low
permeable clays underlying coastal dune sands. Pit construction revealed mostly tightly packed sand at the
pit bases (approximately 4-5 m below surface). Average annual rainfall for the site is 1,023 mm (taken from
the nearby ‘Duffy’ monitoring station). As with the other South Taranaki coastal sites, this site is subject to
strong winds.

The inspection was carried out after sustained heavy rainfall earlier in the day. The site was operational with
casting and powder-coating underway. Small amounts of swarf were noted in the scrap loading yard and
some of this had collected on the filter screens installed in the stormwater sumps. Minor ponding was
observed in low-lying areas of the yard as a result of the
soil.
1.2.3 Site description
The Wellington Landfarm is located on Brown Road, Waitara, on marginal coastal farm land situated on
reworked dune fields. The predominant soil type has been identified as black loamy sand. Vegetation
growth is primarily a mixture of pasture and dune grasses. Prior to the Wellington property consent (7884-1)
being exercised, there were areas of pine (Figure 2) which were subsequently removed and processed.
Average annual rainfall for the site is 1,383 mm
