permit was issued by the Taranaki Regional Council on 28 January 2004 under Section 87(e) of the Resource Management Act. It is due to expire on 1 June 2016. 52 There are 17 special conditions attached to this consent. Special condition 1 requires the consent holder to adopt the best practicable option. Special conditions 2 and 3 relate to offensive odours which are not to occur beyond the site boundary. Special condition 4 states that the consent shall be undertaken in accordance with documentation submitted with the application. Special condition 5 defines emissions from activities excluded from this consent. Special conditions 6 to 10 provide conditions for the management and condition of animals received on site and defines conditions for removal from site. Special conditions 11 and 12 require the consent holder to provide an operations and maintenance manual to the Taranaki Regional Council. Special condition 13 defines pH limits in the effluent holding tanks, and 14 and 15 provide for maintenance of buildings and storage of organic solvent-based degreasing processes. Special condition 16 requires the consent holder to provide a written agreement for the reception of skinned carcasses from the tannery, and the last condition is a consent review condition. The permit is attached to this report in Appendix I. 4.2.4 Discharges of wastes to land Sections 15(1)(b) and (d) of the Resource Management Act stipulate that no person may discharge any contaminant onto land if it may then enter water, or from any industrial or trade premises onto land under any circumstances, unless the activity is expressly allowed for by a resource consent, a rule in a regional plan, or by national regulations. Egmont Tanneries holds discharge permit 5708 to cover the discharge of animal material from tannery operations by burial into land. This permit was issued by the Taranaki Regional Council on 1 May 2001 under Section 87(e) of the Resource Management Act. It is due to expire on 1 June 2016. Special conditions 1, 2 and 3 define disposal in relation to ground and surface water. Special conditions 4 and 5 relate to covering of waste on a temporary and permanent basis. Records of disposal are required to be kept by special condition 6 and the last condition is a review condition. The permit is attached to this report in Appendix I.
4.3 Monitoring programme The monitoring programme for Egmont Tanneries consisted of three primary components in addition to programme liaison and management. 4.3.1 Site inspections 53 The tannery site was visited once 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. The neighbourhood was surveyed for environmental effects. 4.3.2 Chemical sampling The Taranaki Regional Council undertook sampling of both the discharges from the site (site 5, Figure 1) and the water quality downstream of the discharge point and mixing zone (site 6, Figure 1). The effluent tanks were sampled on one occasion to determine potential for odour, and the sample analysed for pH and sulphide. The discharge from the stormwater pipe was sampled on one occasion, and the samples analysed for conductivity, pH, chromium and zinc. This sampling was conducted in conjunction with the low flow survey of the receiving water and included the parameter turbidity. The low flow survey included sampling of discharges from several industries, together with six sites in the Kahouri receiving waters. The samples analysed for those parameters are listed in Table 2. 4.3.3 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 Egmont Tanneries discharge, site D (in the tributary of the Kahouri Stream downstream of the tannery discharge) was used to assess the effects of the discharge on the biological communities of the stream. 4.4 Results 4.4.1 Water 4.4.1.1 Inspections One compliance monitoring inspection of the Egmont Tanneries site was conducted during the 2006-2007 monitoring year. Inspections focused on the waste treatment and disposal systems, and stormwater management, as well as potential sources of odour. Where appropriate, effluent sampling was undertaken in combination with the site inspections.
