14 recorded at upstream site 2 (KHI000353) during both the December 2015 (150 g/m3) and May 2016 (370 g/m3) surveys (Table 2). The exact cause of this result could not be identified but was likely due to rainfall and/or activities in the headwaters of the stream. 2.1.2.2 Industrial discharge site (IND005014) Historical and current results from the industrial discharge from the yellow novaflow pipe (IND005014) samples are presented in Table 3.

upstream 2 (0.724 g/m3). The reason why there was an increase in zinc concentration for the December survey from site upstream 1 to site upstream 2 and a subsequent decrease in zinc concentration from site upstream 1 to site upstream 2 during the May survey is probably related to rainfall. The spring survey is a ‘dry run’ where no rainfall can occur three days prior to sampling while the summer survey is a ‘wet run’ and occurs during heavy rain. The site upstream 1 had a low pH for the 9

This could be attributed to the frequent rainfall during summer, as these flow conditions reduce the influence of the HEP scheme activities. This is evident in the significant improvements in the macroinvertebrate community health at the impact sites, while the control site was in average to above average health. Consequently, based on the current (and previous) survey

Rainfall patterns and intensity, and their influence on fluvial and cliff sediment supply; and • Geomorphology and geological make up of the coast. The rate of erosion of sea cliffs in particular, depends on the following factors (Lumsden, 1995): • Available wave energy producing both impact and abrasion (this can be altered by refraction and diffraction of waves from reefs and off-shore bathymetry); • The presence of absence of a protective beach at the base of the cliffs and type of

Roofing – a simple solution Roofing your bunds avoids human error and dispenses with the need for stormwater valves altogether. Further benefits include: • Stopping rainfall coming into contact with contaminants and washing them into the stormwater system • Preventing accidents from valves being left open
the risk of this happening again. The maximum rainfall (43 mm/hr) used in the application by Remediation (NZ) may be a bit light. This has been reviewed by the applicant in their application. The site needed to be tidied up generally. The untidiness does not given them confidence that it is being managed appropriately. Management plans and improved detail in job descriptions for site and management staff are intended to address this, along with better recording of
