OPERATIONAL PHASE - SURFACE & GROUND WATER QUALITY

                                               Pathogenic free-living protozoans should be absent.
                                               Nuisance organisms: Phytoplankton scums, filamentous algal mats, fungus, leeches should not be present. Direct contact activities
                                               should be discouraged if algal levels of 15 000 - 20 000 cells/mL are present, depending on the algal species. Large numbers of
                                               midges and aquatic worms should also be avoided.
                                               pH: 5.0 - 9.0;
                                               Toxic chemicals: Waters containing chemicals that are either toxic or irritating to the skin or mucous membranes are unsuitable. Toxic
                                               substances should not exceed values in tables 5.2.3 and 5.2.4 in the ANZECC 2000 guidelines; and
                              n       Surface films, oil and petrochemicals should not be noticeable as a visible film on the water nor should they be detectable by odour.
                              Maintaining the vegetated buffer zones
                                               No bare patches;
                                               Minimal entry of grass clippings and plant detritus into the bioretention trenches;
                              Maintaining bloretention trenches
                                               Bioretention trench and outlet weir grate are free of litter;
                                               Bioretention trench is free of silt drapes or disturbances that could affect water infiltration into the trench substrate;
                                               Bioretention trench has healthy growth of the required plant species and is free of weeds;
                              Maintaining Pipe Infrastructure
                                               Evidence of flow along pipework:
                                               No evidence of leaking pipework
                              Maintaining the constructed wetland system
                                               Absence of litter;
                                               Low, manageable presence of weeds;
                                               Water quality conforming to the listed objectives above.

Implementation Strategies             Install all stormwater management devices as outlined in the Stormwater Management Plan (Appendix A);
                              n       The On-Site Manager / Owner shall implement strategies recommended in the Stormwater Management Plan (Appendix A), including:
                                               Vegetated buffer zones are to be maintained by weed removal, mowing of lawns and pruning of gardens, with offsite disposal or
                                               composting of lawn and garden clippings. Composting area to be isolated from stormwater runoff to underground storage tanks;
                                               Avoid leaching of fertiliser nutrients from vegetated buffer zones into stormwater. This may require managing soil pH to manage
