Volume Two 3. Rural Environment Zone 3.3.17.9. Within the Brancott FMU, the Benmorven FMU or the Omaka Aquifer FMU, the bore must not be located within 300m of an existing bore on an adjacent property in different ownership. 3.3.17.10. In all other areas, the bore must not be located within 50m of an existing bore on an adjacent property in different ownership. 3.3.18. Geotechnical bore drilling for the purposes of investigation of sub-surface conditions. 3.3.18.1. The bore must be drilled by a Recognised Professional. 3.3.18.2. A copy of the bore log, including a grid reference identifying the bore location, must be supplied to the Council in a suitable electronic format within 20 working days of the drilling of the bore. 3.3.18.3. On completion of the geotechnical investigation, the bore must be sealed or capped to prevent any potential contamination of groundwater. 3.3.19. Construction of an off-river dam. The construction of a dam does not authorise the taking, use, damming or diversion of water, rules for these activities are in the General Rules. 3.3.19.1. The dam must not be within 8m of a perennially flowing or intermittently flowing river. 3.3.19.2. The dam must not intersect the groundwater. 3.3.19.3. The dam must not be located in, or within 8m of, a Significant Wetland. 3.3.19.4. The dam must not be built within 500m upstream of a dwelling, formed public road or designated rail infrastructure. 3.3.19.5. The construction must comply with the Permitted Activity standards for Excavation, Filling, Indigenous Vegetation Clearance and Non-Indigenous Vegetation Clearance in the Rural Environment Zone. 3.3.19.6. The dam walls must comply with the setbacks for buildings in Standards 3.2.1.4 and 3.2.1.12. 3.3.20. Land disturbance to create and maintain a fire break. 3.3.20.1.

Live stock entering onto, or passing across, the bed of a river. 3.3.21.1. The entering onto or passing across the bed of a river of stock must not involve intensively farmed livestock if there is water flowing in the river. 3.3.21.2. After reasonable mixing, the entering onto or passing across the bed of a river by livestock must not cause any conspicuous change in the colour or visual clarity of a flowing river, measured as follows: (a) hue must not be changed by more than 10 points on the Munsell scale; (b) the natural clarity must not be conspicuously changed due to sediment or sediment laden discharge originating from the activity site; (c) the change in reflectance must be <50%. 3 – 21
