the
environment. Organochlorine pesticides and arsenic can leach
slowly down the soil profile and can contaminate groundwater.
The extent of leaching will depend on the soil type, with greater
leaching occurring in sandy soils. The amount of rainfall or
irrigation will also influence leaching of contaminants through
the soil. Leaching may mean that the highest concentrations
of contaminants are below the soil surface at some sites. Soil
contamination has been measured to a depth of five
volume of wastewater irrigated to land and discharged to water,
compared with the monthly rainfall totals. Rainfall figures are from the
rainfall recorder located at TRC, Stratford. 27
Figure 9 Monthly wastewater volume compared with monthly total kill and total
monthly rainfall, including the R2 value. The closer the R2 value is to 1, the
stronger the relationship. 27

2015/2016 was completed during
2014/2015. Projects with clear benefit to Taranaki were identified
by Council staff and successfully advocated for: a review of a
national High Intensity Rainfall Design System (with benefits for
hydrology, river engineering and civil defence response), and
development of Discrete Water Quality Sampling Standards (SEM
and Policy/NPS-FW implementation benefits). The Envirolink
process for soliciting projects for funding in 2016/2017 has been
1987). The climate is generally
mild, with relatively high humidity and fairly high, evenly distributed annual rainfall .
Soils are volcanic and varied, and include deep ash soils, well-drained alluvial soils
along rivers, and sandy soils near the coast. Slopes within the broader landscape
around the potentially affected sites range from gently undulating to strongly
rolling. The Waiwhakaiho River is a narrow, single channel river, typically 10-m to
30-m wide, set within a

any stormwater treated in accordance with a finalised
Soil Erosion and Sediment Control Plan that has been approved by the Chief Executive,
Taranaki Regional Council, acting in a certification capacity. This finalised plan shall
conform to the Waikato Regional Council’s Guidelines for Soil Disturbing Activities and
shall detail methodology/ design of stormwater drainage from the cleanfill, and
maintenance of sediment control practices, with a specific focus on rainfall events.

Inspection was carried out during an extended period of dry weather. Earthworks
were being undertaken on-site with works on both the access track and drilling pad
underway. No metal had yet been imported to the site, however it was anticipated
that metal would be brought onto site within the next week. The first culvert on the
access track was installed earlier in the day with earthworks continuing about the
