The discharge must not cause flooding on land other than land within the Floodway Zone. 2.17.3.2. The discharge must not cause erosion at, or downstream of, the discharge point. 2.17.3.3. The discharge must not alter the natural course of the receiving water. 2.17.3.4. The discharge point and any associated structure must be maintained so that it is clear of debris and structurally sound. 2.17.3.5. The discharge must not contain stormwater from an area where a hazardous substance is stored unless: (a) the hazardous substance cannot enter the stormwater; (b) there is an interceptor system in place to collect any hazardous contaminant or diverted contaminated stormwater to a trade waste system. 2.17.3.6. If the discharge is from a reticulated community stormwater network administered by the Council as at 9 June 2016, the discharge must not be from stormwater sourced from land zoned Business 1, Business 3, Industrial 1 or Industrial 2. 2.17.4.

After reasonable mixing and disregarding any natural variations, the receiving coastal water quality must meet the following criteria: (a) The natural temperature of the receiving water must not be changed by more than 3°C; (b) The concentration of dissolved oxygen in the stormwater being discharged must not exceed 80% of the saturation concentration; (c) There must be no undesirable biological growth as a result of any discharge of a contaminant into the coastal water; (d) Aquatic organisms must not be rendered unsuitable for human consumption by the presence of contaminants; (e) Any pH change or increase in the deposition of matter on the foreshore or seabed on discharge of contaminant into the coastal water must not have any adverse effect on aquatic life. 2.17.5. Discharge of coastal water to coastal water in the Port, Port Landing Area and Marina and Coastal Marine Zones. 2.17.5.1. The natural temperature of the receiving water must not be changed by more than 3C within 10m from the discharge point. o 2.17.5.2. The concentration of dissolved oxygen in the water being discharge must exceed 80% of the saturation concentration or 6mg/l (whichever is the greater) within 10m from the discharge point. 2.17.5.3. Aquatic organisms must not be rendered unsuitable for human consumption by the discharge. 2 – 24
