Odour
An odour report was submitted with the application, the purpose of the report was to determine
the potential for odour impacts on the proposed hotel due to the Noosa Wastewater Treatment
Plant. The development site is located within approximately 220 metres of the STP. The
accommodation buildings are located approximately 270 metres from the existing Noosa STP
infrastructure.
The odour impact assessment report was prepared on the basis of site-specific odour monitoring
conducted at the STP and use of meteorological and dispersion modelling to assess resultant
odour levels at the proposed development site.
The odour assessment adopted the Queensland Odour Guideline odour criterion of 2.5 Odour
Units, 1 hour average, 99.5%ile which is considered the appropriate basis for assessment, and
notably the benchmark considered in Planning and Environment Court appeals. The criterion
requires the prescribed odour concentration to be achieved 99.5% of the time, being measured at
one-hour intervals.
Council’s consulting odour expert reviewed the development application odour report and the
response to information request and considers that the reporting provides adequate assessment
for the purpose of understanding the potential odour impact of the STP upon the proposed
development. The application material has demonstrated the proposed buildings and pool and
communal area between the buildings comply with the odour criterion at all hours of the day. The
swimming pools and tennis courts comply between 6am to 12am and 6am to 10pm respectively.
Conditions establishing times which these areas can be used were proposed by Council’s external
consultant, the times are reflective of the hours which the areas comply with the odour criterion.
The conditions are included within the recommendation of this report.
Comments by Council’s consulting odour expert include:
     This further peer review of the odour impact assessments, modelling and information
     responses identifies that odour from the Noosa STP does impact upon the proposed
     development and that exceedance of the 2.5 OU 1 hour 99.5%ile criterion will occur in
     outdoor areas to the North of the proposed accommodation buildings and compliance is just
     achieved at the facades of the proposed buildings nearest the STP.
     The development is proposed to be located in relatively close proximity to the STP and, on
     this basis, appropriate care and consideration is necessary to ensure that future
     development does NOT:
     (i) Experience excessive odour impact leading to potential complaints; and
     (ii) Does not result in an unacceptable reverse amenity constraint upon the existing and
     future operation of the WWTP (on the basis of potential odour complaints).
     Given that the odour assessment identifies compliance in some outdoor areas (pool,
     gardens and tennis court) is not achieved at all times, and that compliance is only achieved
     on the basis of limited hours of use of these outdoor areas it is considered appropriate to
     limit, by way of conditions, the hours of use (access) of certain outdoor areas to prevent
     potential adverse odour experiences and complaints by guests.
     Further, as the odour impact assessment identifies that 2.5 Odour Unit, 1 hour 99.5%ile is
     predicted just external the façade of the nearest accommodation buildings, it is considered
     appropriate to include conditions requiring accommodation use areas be fully air-
     conditioned and that outdoor fresh makeup air to the rooms be drawn from locations as
     distant from the STP as practical.
     The requirement for disclosure of the potential for odour to guests should also be
     considered to minimise the potential for complaints about perceived odour.
