exposure of ASS during the works      a Site Based Acid Sulfate Soils Management Plan.                                               during
where possible and if exposure is     Where excavations occur in medium or high risk areas, any materials excavated or               excavation
necessary manage and treat            exposed should be tested and if required treated and neutralised.                              works
accordingly.
                                      Develop an ASS treatment pad to Soil Management Guidelines standards in a suitable
                                      location.
                                      Neutralisation treatment liming rates used must be in accordance with those prescribed
                                      under the Acid Sulfate Soils Management Plan recommendations.
                                      Neutralised material must be reused on-site where possible/feasible.
                                      Conduct verification testing of treated material prior to material re-use as fill or offsite
                                      removal.
                                      The construction works should be sequenced in order to minimise exposure of ASS
                                      where possible. For example no more ASS soils should be exposed than can be
                                      treated in the containment and treatment areas at any given time.
                                      Excavation works of ASS material must be staged in such a way to ensure that the
                                      excavated material is treated as soon as practicably possible and that exposed soil
                                      surfaces are refilled within, and not exposed for longer than, 24-48 hours.
                                      Appropriate management, treatment and disposal of potentially acid contaminated
                                      water runoff and leachate shall be designed and implemented.
Record keeping.                       Maintain appropriately detailed records of the following:                                      Ongoing        Contractor
                                            Results of any Acid Sulfate Soils testing as required by this Acid Sulfate
                                             Soils Management Plan, including verification testing;
                                            Location of soil during the treatment process and rates / total quantities of
                                             ameliorant added to the soil requiring neutralisation; and
                                            Results of surface and ground water monitoring as required by the Acid

                                      Contractor to record all onsite and offsite ASS material movements in a waste tracking
                                      form and provide to Principal at end of project.
                                      Ensure all records and reports are made available to relevant administering authorities
