marine outfall discharge on the local intertidal communities were not evident from the 2022
summer survey results. Two potential impact sites had greater species richness and diversity results than the
control site, Waihi Reef, while the other site (350 m NW of the outfall) had recently experienced a natural
rock fall event and was buried by large boulders and other debris. Seven years ago, the site 200 m SE of the
outfall was also buried during a rock fall event. Species richness and diversity

the time of the inspection. The stormwater system was working well, with all stormwater being collected and
directed for treatment prior to discharge from the site. The site was tidy and processes appeared to be well
managed with no spills or stains evident on the ground. Operationally good practices were being adhered
to with drip trays and chemical bunding in use. The skimmer pits were full, free of hydrocarbon

1.3.1 Water abstraction permit
Section 14 of the RMA stipulates that no person may take, use, dam or divert any water, unless the activity is
expressly allowed for by a resource consent or a rule in a regional plan, or it falls within some particular
categories set out in Section 14.

f. Cliff erosion
Sedimentary rocks in cliffs in the ‘papa’ areas of north and south Taranaki are relatively
young geologically speaking, so are soft, unconsolidated and easily eroded. Cliffs with
waves lapping at the base at high tide are vulnerable to episodic erosion events with the
steep faces falling away catastrophically. Compounding this process is groundwater seepage
through the cliffs which intensifies after heavy rain. When the top layers are saturated, they
