PLANNING & ENVIRONMENT COMMITTEE MEETING AGENDA                             6 FEBRUARY 2018


Condition 49
49.   Where stormwater runoff from the site will enter the Noosa Springs Lake System, Quarterly
      monitoring is required of stormwaters directed from the development to the Noosa Springs
      Lake System. Monitoring must be undertaken by a suitably qualified person using NATA
      accredited methods for the following parameters.
         Nitrite plus Nitrate as N (NOx)
         Total Kjeldahl Nitrogen (TKN)
         Total Nitrogen as N (TKN + NOx)
         Total Nitrogen as N
         Total Phosphorus as P
         Reactive Phosphorus as P (Dissolved)
         Reactive Phosphorus – Filtered
      Water quality monitoring results must be retained in electronic form by the property owner
      for a minimum of 5 years and must be made available to Noosa Council on request. This
      monitoring must continue until notified by Noosa Council that it is no longer needed.
Applicant’s requested change
It is contended that a two (2) year monitoring period is an appropriate period within which a
measurable data set is able to be collated demonstrating appropriate stormwater quality
outcomes from the development. It is suggested that the previous condition be reintroduced with
amendments as outlined below:

         Reactive Phosphorus as P (Dissolved)
         Reactive Phosphorus - Filtered
      Water quality monitoring required by this condition must commence at the commencement
      of operation of the first stage of the development until two (2) years following the
      completion of the final stage of the development. Water quality monitoring results must be
      retained in electronic form by the property owner for the duration of the monitoring and
      must be made available to Noosa Council on request.
Assessment
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.
