B-7 – Area 7 - Assessment of Environmental Effects 135 Discharge Receiving Environment Alternative Methods of Discharge See Section 3.4 (Closure and Rehabilitation) and Figure 30 of this AEE and Sections 11.19 and 11.20 of EGL (2022c) for further description of the discharges. discharge, it will be allowed to overflow to the Ruahorehore Stream via a spillway. This can be undertaken as a permitted activity given the water is clean and will not result in adverse effects. Discharge of contaminants to air. Refer to Section 2.18 (Meteorology and Air Quality) of this AEE Beca (2022) considered alternative methods of managing the proposed discharges to air. The recommended methods are those considered to be most appropriate considering the nature of those discharges and the receiving environment. 7.10 SECTION 107 OF THE RESOURCE MANAGEMENT ACT 1991 Section 107(1)(a) and (b) of the RMA specify that the consent authority shall not grant a discharge permit allowing the discharge of water / contaminant into water or land if, after reasonable mixing, the contaminant or water discharged (either by itself or in combination with the same, similar, or other contaminants or water) is likely to give rise to all or any of the following effects in the receiving waters: the production of any conspicuous oil or grease films, scums or foams, or floatable or suspended materials; any conspicuous change in the colour or visual clarity; any emission of objectionable odour; the rendering of freshwater unsuitable for consumption by farm animals; or any significant adverse effects on aquatic life. Based on the assessments in Sections 5.5 (Groundwater and Surface Water) of this AEE, the discharge of water / contaminants to water or to land in circumstances where it may reach water will not give rise to any of the effects listed above after reasonable mixing.
