Condition 50
2.    For a minimum of 5 rainfall events per year, stormwater at the following locations and times
      must be collected and sampled for Total Nitrogen, Total Phosphorous and Total
      Suspended Solids using NATA accredited methods:
      a.   The release point from Precinct E2 for all waters directed to the Noosa Springs lake
           system.
      a.   At monitoring point W6 shown on Plan A – Water Quality Monitoring Locations Noosa
           Springs by Jelliffe Environmental (Qld) Pty Ltd.
      The time for collection of water samples for monitoring must be quantified by the
      applicant’s hydraulic engineer within the Operational Works application for stormwater.
      The time for water quality monitoring shall be a minimum of the time of concentration for all
      waters from Precinct E2 destined for the Noosa Springs Lake System to reach the release
      point from Precinct E2, and within a maximum of 24 hours of commencement of rainfall
      events that generate runoff from Precinct E2.
      Water quality monitoring required by this condition must commence at the commencement
      of operation of the first stage of the development until five (5) years following the
      completion of the final stage of the development
Applicant’s requested change
It is requested that this condition be amended to align requested monitoring periods detailed in
New Condition 49 above, to read as follows:
50.   For a minimum of 5 rainfall events per year, stormwater at the following locations and times
      must be collected and sampled for Total Nitrogen, Total Phosphorous and Total
      Suspended Solids using NATA accredited methods:
      a.   The release point from Precinct E2 for all waters directed to the Noosa Springs lake
           system.
      b.   At monitoring point W6 shown on Plan A – Water Quality Monitoring Locations Noosa
           Springs by Jelliffe Environmental (Qld) Pty Ltd.
      The time for collection of water samples for monitoring must be quantified by the

      waters from Precinct E2 destined for the Noosa Springs Lake System to reach the release
      point from Precinct E2, and within a maximum of 24 hours of commencement of rainfall
      events that generate runoff from Precinct E2.
      Water quality monitoring required by this condition must commence at the commencement
      of operation of the first stage of the development until five (5) two (2) years following the
      completion of the final stage of the development
Assessment
As per the request to amend Condition 49, the request to amend this condition was referred to
Council’s Environment Officer who advised:
2 years of monitoring data is not sufficient to determine any trends as a result of the
development. 5 sample events are the general minimum to establish statistical information if
necessary.
Due to the need to obtain suitable sample data it is recommended that this condition remain
unchanged.
