24 March 2005, under Section 87(e) of the Resource Management Act. It is due to expire on 1 June 2022. Special conditions 1, 2, 3 and 4 relate to adopting the best practicable option and exercising the consent in accordance with the application, and notification requirements. Special condition 5 defines the information to be included in a Waste Burial Management Plan, and that the disposal shall be in accordance with this plan. 14 Special conditions 6 and 7 define the type of product and circumstances (emergency) in which this consent should be used. Special conditions 8 and 9 define boundaries beyond which no adverse effects shall occur and special conditions 10, 11, 12, 13, and 14 define the requirements to keep records of disposal, and burial cover and rehabilitation requirements. The last two conditions are consent lapsing and review requirements. The permits are attached to this report in Appendix I. 2.3 Monitoring programme The monitoring programme for Taranaki Abattoirs consisted of three primary components in addition to the programme liaison and management. 2.3.1 Site inspections The abattoir and rendering site was visited five times during the monitoring period for routine site inspections. With regard to consents for the abstraction of or discharge to water, the main points of interest were plant processes with potential or actual discharges to receiving watercourses, including contaminated stormwater and process wastewaters. Air inspections focused on plant processes with associated actual and potential emission sources and characteristics, including potential odour, dust, noxious or offensive emissions. Sources of data being collected by the consent holder were identified and accessed, so that performance in respect of operation, internal monitoring, and supervision could be reviewed by the Council. The neighbourhood was surveyed for environmental effects. 2.3.2 Chemical sampling The Taranaki Regional Council undertook sampling of both the discharges from the site (site 2, Figure 1) and the water quality upstream and downstream of the discharge point and mixing zone (sites 1 and 3, Figure 1). The aerobic pond discharge (site 2) was sampled on five occasions, and the sample analysed for conductivity, dissolved oxygen, ammonia and chemical oxygen demand. On one of these occasions (and in conjunction with the low flow survey of the receiving water), pH, suspended solids, biochemical oxygen demand, total nitrogen and total phosphorus were also analysed.
15 The water-monitoring programme also included one shared summer low flow survey of water quality in the Kahouri catchment. The programme specified that the discharges from the abattoir, tannery and Contact Energy's power station were to be monitored, together with six sites in the Kahouri receiving waters. The samples analysed for those parameters listed in Table 2. 2.3.3 Biomonitoring surveys One shared biological survey was performed in seven sites in the Kahouri Stream catchment on 17 April 2007 to determine whether or not the discharges from the various industries have had a detrimental effect upon the communities of the stream. The location of these sites is shown in Figure 1. When assessing the effects of the Taranaki Abattoir discharge, site A (in the Kahouri Stream, upstream of the tributary that receives the abattoir discharge) and C (in the Kahouri Stream, 50 m downstream of the tributary that receives the abattoir discharge) were used to assess the effects of the discharge on the biological communities of the stream. 2.4 Results 2.4.1 Inspections 2.4.1.1 Routine inspections Five routine inspections of the Taranaki Abattoir site were conducted during the 2006-2007 monitoring year. Inspections focus on the waste treatment and disposal systems, and on operation of the rendering plant, as a potential source of odour. Where appropriate, effluent sampling was undertaken in combination with the site inspections. Additional inspections were undertaken in relation to complaints. The first compliance monitoring inspection was undertaken on 14 December 2006. The inspection was undertaken with Frank Watty, the plant manager at the time. The rendering area looked tidy and the only off site material being received was frozen pork bones. It was noted that the area that is washed down near the tallow tank needs to have the waste water directed to the waste water system, and that it should not be running off towards the drain, as it contains spilt material e.g. meal. The pressure release valve had been changed, and is now a cap which pops off when pressures get too great. The wastewater ponds were checked, with only faint odours emanating from them. Sewage fungus was noted in the receiving water body below the wastewater discharge. It was not known how far downstream this sewage fungus extended. The site appeared to be well managed. On 20 December 2006 the Company was notified that a noticeable odour was present some distance from the abattoir. The site manager tracked this down to a new employee getting the pressures on the gas release slightly wrong. The following inspection was completed on 1 February 2007. Again, the site manager accompanied the officer during the inspection. There was a general clean up planned for site, including repairing of the driveway. The rendering area was looking clean, with the only issues being some material on the roof where it had fallen off the conveyor, a small leak from the tallow bund, and fat in the stormwater drain leading away from the fat trap area. The fat was sourced to the basket from the fat trap being placed where fat could enter the stormwater system. It was requested that rendering
