1.2.1 Other resource consents A total of 29 resource consents, in addition to those referred to above, provide for a range of other activities in the Kahouri Stream catchment. 1.2.1.1 Water permits There is one consent held by a farmer to divert an unnamed tributary of the Kahouri Stream for land upgrading purposes. 1.2.1.2 Discharge permits Eighteen consents are currently held to discharge dairy shed wastewater, eight from oxidation ponds to the Kahouri Stream and its tributaries, and nine to land plus one that permits a discharge to land and water. An additional consent allows Taranaki Farmers to discharge effluent from Stratford stockyards to land. Standard conditions for the Taranaki region are imposed, controlling discharge rate and composition and effects on the receiving environment. Taranaki Stock Car Club Inc holds consent to discharge up to 25 litres per second of stormwater from a stock car racing complex to a tributary of the Kahouri Stream. Conditions define the component concentrations that shall not be exceeded in the discharge, and the effects that shall not be observed in the tributary below the 50metre mixing zone. Shell New Zealand Limited holds consent to provide for seepage from the site of a petroleum storage tank. 1.2.1.3 Land use consents Seven land use consents are held; two for bridges, one for a pipeline and four for culverts. 1.3 Monitoring programme 1.3.1 Introduction Section 35 of the Resource Management Act sets out an obligation for the Taranaki Regional Council to gather information, monitor, and conduct research on the exercise of resource consents, and the effects arising, within the Taranaki region. The Taranaki Regional Council may therefore make and record measurements of physical and chemical parameters, take samples for analysis, carry out surveys and inspections, conduct investigations, and seek information from consent holders. The monitoring programme for the Kahouri Stream catchment consisted of four primary components. 1.3.2 Programme liaison and management There is generally a significant investment of time and resources by the Taranaki Regional Council in ongoing liaison with resource consent holders over consent 4
5 conditions and their interpretation and application, in discussion over monitoring requirements, preparation for any reviews, renewals, or new consents, advice on the Council's environmental management strategies and the content of regional plans, and consultation on associated matters. 1.3.3 Site inspections Each site was scheduled for inspection in the monitoring programme. These inspections are detailed in the relevant sections related to each industry. 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. 1.3.4 Chemical sampling The Taranaki Regional Council undertook sampling of both discharges from industrial sites and the water quality in the receiving Kahouri Stream catchment. The locations of these sites are shown in Figure 1. The water-monitoring programme included one shared summer low flow survey of water quality in the Kahouri catchment. The programme specified that the discharges from the abattoir, tannery, Taranaki Galvanizers 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 are listed in Table 2. 1.3.5 Biomonitoring surveys One shared biological survey was performed at 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.
