CONSTRUCTION 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) and the Erosion
and Sediment Control Element (Section 3.1).

Performance Criteria                          n   Performance requirements for water discharge(s) during construction of the site include (in accordance with the
                                                  construction phase objectives in the Noosa River: Environmental Values and Water Quality Objectives 2007 and
                                                  Queensland Water Quality Guidelines 2009):
                                                         Total suspended solids <50 mg/L and/or 80% reduction in suspended solids compared to untreated stormwater
                                                         runoff from the developed part of the site;
                                                         60% reduction in Total Phosphorus compared to untreated stormwater runoff from the developed part of the site;

                                                         45% reduction in Total Nitrogen compared to untreated stormwater runoff from the developed part of the site;
                                                         pH 6.5 - 8.5; and
                                                         Turbidity: Discharge <50NTU and/or released waters from approved discharge point/s have turbidity less than 10%
                                                         above that of receiving waters (measured immediately upstream of the site).
                                              n   No exposure of acid sulfate soils (ASS) to the external environment;
                                              n   Correct management of acid sulfate soils if exposure occurs;
                                              •   No discharge of contaminated water to receiving waters;
                                              n   No deterioration in water quality in adjacent surface waters; and
                                              •   No deterioration in groundwater quality.
Implementation Strategies                     n   Implement all erosion and sediment temporary control measures (as outlined in the Soil Erosion and Sediment Control
                                                  element of this EMP; Section 3.1, and the Stormwater Management Plan / Sediment and Erosion Control Plan Appendix
                                                  A) prior to the commencement of bulk earthworks;
                                              n   Implement all Hazardous Substances and Waste Management implementation strategies (as outlined in the EMP;
                                                  Section 3.3 & Section 3.10);
                                              n   All contractors are to be trained during site inductions on the identification of Potential Acid Sulfate Soils (PASS) and ASS.
                                                  Common indicators of PASS or ASS include:
