The site was busy with normal operations. Traffic was particularly busy within the scrap area and some swarf
was observed tracking to the drains. All drain screens were in place and appear to be regularly maintained
to prevent blocking. All hazardous chemicals were appropriately contained. Rainwater within bunding was at
a low level. Spill kits were in place throughout the site and

shown in Figure 3 for the Taranaki region which shows the strong spatial variation.
Heavy rainfall is meteorologically defined to be “when greater than 100 mm of rain falls
within 24 hours, or a pro rata amount” (Thompson et al. 2006). The regions heaviest
rainfall occurs when warm moist northerly airflow flow from the tropics flows onto the
district. These conditions can persist when fronts lying

the South Taranaki ring plain contains a very sparse bird life, owing to the lack of
habitat (Fish and Game, 2006).
2.1.2 Hydrological values
Intact small streams and wetlands provide natural flood control, absorbing significant
amounts of rain water and runoff before saturation and consequent flooding occurs.
Natural stream channels tend to meander and provide a variety of substrate types
which slow the flow and energy of water, aiding seepage
