OPERATIONAL PHASE - SURFACE & GROUND WATER QUALITY

This element to be read in conjunction with the Stormwater Management Plan & Sediment/Erosion Control Plan (Simmonds & Bristow, 2010) (Appendix A). Relevant
information has been extracted from this document for inclusion in this element of the EMP.

Performance Criteria          •    No deterioration in water quality in adjacent waters;
                              •    Long-term median stormwater quality objectives as recommended in the Stormwater Management Plan / Sediment and Erosion Control Plan
                                   (Simmonds & Bristow, 2010) (Appendix A):
                                          Suspended solids <15 mg/L:
                                          Total phosphors <35 ug/L;
                                          Total nitrogen <350 ug/L; and
                                          pH 5.0 - 7.0.
                              Maintaining 3m3 rainwater tank volume associated with each beach shack
                              n    Water quality parameters should conform to the ANZECC 2000 guidelines for primary contact (to be used for laundry, toilet use and
                                   irrigation) as outlined below:
                                          Microbial: the median bacterial count should not exceed 150 faecal coliform organisms/100mL or 35 enterococci organisms/100mL.
                                          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
                                          Surface films, oil and petrochemicals: should not be noticeable as a visible film on the water nor should they be detectable by odour.
                              Maintaining underground rainwater tanks associated with the ornamental garden Irrigation scheme
                              n    Water quality parameters should conform to the ANZECC 2000 guidelines for secondary contact (to be used for irrigation) as outlined below:
                                     -    Microbial: Median bacterial count should
                                                                             ............. not
                                                                                            ... exceed
                                                                                                 .     1000 faecal coliform organisms/100mL or 230 enterococci organisms/100mL.
