23.   The Geotechnical Engineer or other suitably qualified person must identify any
      infrastructure expected to be located in the expected cone of depression and likely to be
      within previously un-oxidised Potential Acid Sulfate Soils. Dilapidation report of this
      infrastructure must be completed prior to commencement of any dewatering activities
      on the site.
24.   All excavation and dewatering works must be undertaken in a manner that will not cause
      environmental harm or damage to surrounding infrastructure as a result of the
      developments interaction with actual or potential Acid Sulphate Soils. An environmental
      professional with a minimum of 5 years’ experience in the management and treatment
      of Acid Sulfate Soils must be engaged to supervise and certify compliance with this
      condition.
25.   All treated material must undergo verification testing to achieve neutralisation in
      accordance with the Queensland Acid Sulfate Soil Technical Manual: Soil Management
      Guidelines v4.0.
26.   Surface waters must be sampled and tested at a NATA certified laboratory to confirm
      the following water parameters are met prior to release from the site:
      a.    a pH range of 6.5-8.5 pH units;
      b.    50mg/L maximum total suspended solids concentration;
      c.    0.3mg/L maximum total iron concentration;
      d.    0.2mg/L maximum total aluminium concentration.
27.   Groundwater monitoring bores must be established and installed by a Geotechnical
      Engineer or other suitably qualified person experienced with Acid Sulfate Soils
      Management. The location of the groundwater monitoring bores must be certified by the
      Geotechnical Engineer or other suitably qualified person to be sufficient to identify any
      changes in groundwater levels as a result of proposed construction activities.
28.   Groundwater levels must, be monitored weekly for at least one month prior to
      construction activities likely to affect groundwater levels and daily during construction of
      those activities. Within 24 hours of identifying a reduction in groundwater levels below
      the lowest measured pre-construction levels, the Geotechnical Engineer must provide
      Council and Contractor with remediation strategies, and these must be implemented to
      prevent harm to receiving environments.
29.   All pipework within the saturated zone, that outlets direct to waterways must be fitted
      with buried headstocks at suitable intervals to prevent ongoing dewatering of
      groundwater along pipework bedding.
4.    REASONS FOR INCLUSION OF CONDITIONS

The proposal is subject to specific built form parameters outlined in The Noosa Plan.
5.    ADVISORY NOTES

The following notes are included for guidance and information purposes only and do not form
part of the referral agency conditions:
      Aboriginal Cultural Heritage Act 2003
1.    There may be a requirement to establish a Cultural Heritage Management Plan and/or
      obtain approvals pursuant to the Aboriginal Cultural Heritage Act 2003 (ACH Act).
      The ACH Act establishes a cultural heritage duty of care which provides that: “A person
      who carries out an activity must take all reasonable and practicable measures to ensure
      the activity does not harm Aboriginal cultural heritage”. It is an offence to fail to comply
      with the duty of care. Substantial monetary penalties may apply to individuals or
