Katestone Recommended Response

 

The analysis of the site-predicted

impacts.

10. Supply of the requested PRTMET
file is requested to assist in review of this
matter. Provide justification as to
whether the assessment has suitably
considered calm/ low wind speed
conditions.

Katestone has provided the requested file (NoosaSprings_Prtmet.DAT) in a separate email
dated 23 August 2021. The windrose for the site indicates that six percent of winds are less
than 1 m/s at the site.

Katestone has provided an excel spreadsheet (AMG_NewPlan_Results.xlsx) containing a

12. Please describe how the results for
the reduced hours for the outdoor
recreation areas was generated, i.e
removal of predicted concentrations
from unoccupied hours and
regeneration of 99.5th percentile or
maximum?

Predicted odour concentrations for the hours when recreational areas are allowed to be
occupied were generated as follows:

1. Removed 1-hour concentrations for hours when recreational areas were not occupied. (e.g.
for the tennis court hours 9pm to 6am, for the swimming pool hours 8pm to 6am)

2. Calculate 99.5" percentile on the remaining hours.

 

 

13. For Figure 12 and Figure 13, clarify
the location of the receptor(s) used to
generate these figures, eg
accommodation or outdoor recreation
areas.

 

The location (508.697kmE 7078.109kmS) is representative of the outdoor recreational areas.
It is located between the pool and tennis courts. The figures included all hours of the year
(8760 hours). (The timeseries data (Odour_met.csv) is provided in a separate email dated 23
August 2021.)
