PO10 Development involving the use, storage or generation of hazardous chemicals minimises hazards and associated risks. Note – If development does not comply with AO10.1, in addition to PO10 development will be required to be assessed against PO12, PO13, PO14 and PO15. Note – To assist in demonstrating compliance with the performance outcomes, a Hazard Assessment Report may be required to be prepared and submitted by a suitably qualified person in accordance with the Planning Scheme development Code for Hazardous Industries and Chemicals. Note- Terms used in this section are defined in Model Planning Scheme development Code for Hazardous Industries and Chemicals. AO10.1 Development that involves the storage or handling of hazardous chemicals: (a) complies within the self-assessable thresholds contained within Table 9.4.5.3b development thresholds and complies with the self-assessable criteria contained within Table 9.4.5.3d criteria for Hazardous chemicals; (b) does not involve identified assessable thresholds contained within Table 9.4.5.3c Assessable development thresholds; Note – used in this section are defined in Model Planning Scheme development Code for Hazardous Industries and Chemicals. Contaminated land PO11 Development is located and designed to ensure that and nearby sensitive land uses are not exposed to unacceptable levels of contaminants. AO11.1 Development is located where soils are not contaminated by pollutants which represent a health or safety risk to users, or contaminated soils subject to a development are remediated prior to plan sealing, operational works permit, or issuing of building works permit. For assessable development Hazardous chemicals Note – Terms used in this section are defined in Model Planning Scheme development Code for Hazardous Industries and Chemicals. PO12 Off sites risks from foreseeable hazard scenarios involving hazardous chemicals are commensurate with the sensitivity of the surrounding land use zones. Note – To assist in demonstrating compliance with the performance outcomes, a Hazard Assessment Report may be required to be prepared and submitted by a suitably qualified AO12.1 Off-site impacts or risks from any foreseeable hazard scenario does not exceed the dangerous dose at the boundary of land zoned for vulnerable or sensitive land uses as described below: Dangerous dose: (a) for any hazard scenario involving the release of gases or vapours:
within a Local Government “flood hazard area” are located and designed in a manner to minimise the likelihood of inundation of flood waters from creeks, rivers, lakes or estuaries. Note – To assist in demonstrating compliance with the performance outcomes, a Hazard Assessment Report may be required to be prepared and submitted by a suitably qualified person in accordance with the Model Planning Scheme development Code for Hazardous Industries and Chemicals. (a) bulk tanks are anchored so they cannot float if submerged or inundated by water; and (b) tank openings not provided with a liquid tight seal, i.e. an atmospheric vent, are extended above the relevant flood height level. AO15.2 The lowest point of any storage area for packages >2,500 L or kg is higher than any relevant flood height level identified in an area’s flood hazard area. Alternatively, package stores are provided with impervious bund walls or racking systems higher than the relevant flood height level. 9.4.5.3.b – Self-assessable development thresholds Hazardous chemical PG or type Applicable storage and handling type Threshold quantity Exclusions Flammable gases – DG class 2.1 N/A Cylinder stores with natural ventilation > 1,000 – < 5,000 L (a) connected to a consuming device, fuel burning appliance or within a refrigeration system (b) Tanks with a WC > 500 L (c) Aerosols with a WC < 1 L (d) Cylinder exchange facilities that comply with AS1596, (e) Cylinders stores with any of the following attributes: within or attached to a building, mechanically ventilated.
