Results 2.1 Water 2.1.1 Inspections Six inspections were carried out at the Rimu Production Station and associated wellsites in the 2014-2015 year. The following was found during the inspections: 15 July 2014 The site was found to be neat and tidy. Recent heavy rainfall had not resulted in any problems, with

Zealand, where high rainfall and poor drainage provide ideal conditions for it to establish. Due to land clearance and drainage, it is now quite scarce or absent over much of its former range. Swamp maire is an early to mid-succession canopy species that is frost tender and shade intolerant. It requires high light levels, caused by some disturbance event such as tree fall, for new seedlings to establish. SWAMP MAIRE IN TARANAKI Historically, swamp maire was plentiful

All aerators except the large Fonterra aerator were operating. A set of ‘4 Earth’ aerators had been set up on the pond inlet. There were numerous birds present on the pond with an estimated excess of 1,000 mallard and paradise ducks. Minor amounts of stormwater were noted in the holding pond following the recent wet

During high rainfall events, the maturation pond can overflow into the neighbouring emergency overflow/storage detention pond (capacity approximately 65,000 m3, NIWA 2012) with wastewater then being passed back into Pond 1.

number of land disposal systems and dual systems has been steadily increasing in recent years. The requirement for discharge to land would generally be phased in as current resource consents are renewed. Discretionary consents for discharge to water will still be available for the small percentage of farmers unable to discharge to land because of high rainfall and particular soil types. High levels of treatment would be required. Better farm management would also
samples were collected for analysis. One abatement notice was issued in relation to untreated silt and sediment discharges leaving the site due to heavy rainfall inundating the capacity of the silt and sediment controls. Four samples were obtained and analysed in conjunction with this incident. Follow up inspections found the abatement notice had been adhered to. These discharges were deemed unlikely to have any significant adverse effect on receiving waters as discharges were temporary in

The catchment geology in the Haehanga is dominated by Papa mudstones which are easily eroded and can contribute to poor water clarity in the water ways. 4.2.2.1 Haehanga Stream and tributaries The Haehanga Stream is an entrenched meandering stream below the site, but adjacent the composting facility the stream has been modified
