Nitrogen, in particular ammoniacal nitrogen measurements in surface waterways indicates a much higher nitrogen loss to water is occurring than is a predicted by RNZ's OVERSEER analysis.20 This, together with groundwater results, suggests the irrigated wastewater is draining to groundwater with little renovation in the soil - "[t]his occurs when either the rate of
been an increase in the amount and rate of stream modification. The Taranaki Regional Council (the Council) and the wider community recognise the positive consequences of modifying small streams and that in some circumstances their modification may be appropriate. However, it is also recognised that small stream modification may result in significant adverse effects upon instream habitat and/or on other users and uses of freshwater, and that these effects should be avoided, remedied or
or it falls within some particular categories set out in Section 14. The Council determined that the application to take groundwater fell within Rule 49 of the Regional Freshwater Plan for Taranaki (RFWP) as the rate and daily volume of the groundwater abstraction may have exceeded that of the permitted activity (Rule 48). Rule 49 provides for groundwater abstraction as a controlled activity, subject to two conditions: • The abstraction shall cause not more than a 10% lowering of
an exceedance of the suspended solids limit on the Company’s stormwater discharge consent. During the year, TBS Coatings Limited demonstrated a good level of environmental and high level of administrative performance with the resource consents. One dust complaint was received, but this was not substantiated at the time of investigation. However, an exceedance of the dust deposition rate was observed in one of the five gauges deployed, which was likely to be a result of re-suspended yard
and recorded a peak of 15.192m. The estimated return period at Riminui was a 1-in- 37 year event. However this was based only on stage, and not corrected for flow or changes within the river system. The channel clearing works may have increased the rate of flow and at the same time, normal continuous river bank erosion worked to slow it down. 7.2.1.1 River level data The topography of the Waitotara catchment makes it extremely difficult if not impossible to establish sites for river
Limited and five at New Zealand Oil Services Limited. Water samples were collected for physicochemical analysis on selected inspections. During the period under review, Port Taranaki Limited obtained a ‘good’ rating for environmental and administrative performance and compliance with the resource consents. There was one incident in relation to port maintenance and one breach of stormwater discharge limits which required further investigation. The environmental performance of Port Taranaki

each FMU). Although indigenous forest is the dominant land cover in the upper sections of the Southern Hill Country and Northern Hill Country FMUs, the proportions of stream reach graded in band A appear relatively high considering that the geology and terrain in both of these FMUs are particularly prone to high rates of sediment erosion. It should be noted that there was limited available monitoring data to calibrate the model in these areas, with data from neighbouring
development of the region’s resources. 1.1.4 Evaluation of environmental and administrative performance Besides discussing the various details of the performance and extent of compliance by the consent holders, this report also assigns a rating as to each Company’s environmental and administrative performance during the period under review. Environmental performance is concerned with actual or likely effects on the receiving environment from the activities during the monitoring year.
