produced water is disposed of by deep well injection. Stormwater from the production station is collected and discharged at three separate points. The water level in the firewater pond in the north western corner of the site is maintained by an abstraction from the Ngaere Stream. Overflow due to rainfall entering this pond is discharged to land and to the Ngaere Stream to the north of the pond. Stormwater from the process areas is directed to a large API separator system to the north east of
contributing waterways drain off the high, steep, unstable slopes of Mount Taranaki and are capable of transporting large amounts of coarse sediment as bed load, as well as fine sediment (TRC, 2011). Additionally, the orographic influence of Mount Taranaki results in high local rainfall and attracts high intensity rainfall events in the headwaters of rivers originating on the Maunga. This means sediment transport rates, and the frequency of sediment transport events, are likely to be relatively high in the
With a loading rate of 4mm/day for the disposal field. • 30% buffer area for the disposal field to allow for separation from water ways and any land unsuitable for disposal which may be present in the land parcel. • Disposal only when the day’s rainfall is <10mm. • The approximate 4 year period for which data is supplied is representative of all foreseeable flow scenarios. • The scheme should give consideration to the maximum flows, successive days of maximum flows and be
points (when allowed) the Company is required to put out signs at predefined locations discussing limited access. At no point during this monitoring period were lake levels below the usable range, therefore, any inability to use the ramp was a result of maintenance issues. Boat ramp usability is discussed later in this report. During large rainfall events the 78 m upper limit was briefly exceeded during this monitoring period. The Company is to page 13 endeavor to ensure

The rainfall recorded at the Inglewood WWTP council weather station in the month prior was 147 mm. NPDC contractors were onsite carrying out maintenance around the primary screen influent area. Mild odours were noted in the vicinity of the step screen. The primary
Experts generally agree that climate change is affecting New Zealand’s weather patterns. In Taranaki, rainfall is predicted to decrease in summer and increase in winter. An increase in extreme rainfall is likely as the temperature increases through the 21st century, potentially increasing both the severity and frequency of flooding. South Taranaki is predicted to become drier on average, with more frequent droughts. Gale and storm force winds from the west are also predicted to

is owned by the Company, and consists of steep eroded hillsides, multiple side gullies, and small river flats distributed along its length. The area receives more rainfall than the northern Taranaki coastline to the south-west. Soils are generally poor and highly erodible. Patches of bush and planted trees cover most of the hillsides, with grasses over the remainder and the flats. 1.3 Process description The Company’s operations include composting, quarrying and vermiculture operations
