Further to SEQ Water’s Third Party Advice dated 23 August 2016 we now respond to each of the items
raised.

1.   In accordance with the Seqwater Development Guidelines, development is to ensure that
     stormwater is of a quality that is fit for purpose as drinking water supply. Seqwater recommends
     that the applicant demonstrate that the reduction in pollutant load calculations can achieve the
     relevant Water Quality Objectives identified in the Environmental Protection (Water) Policy 2009. It
     is recommended that the applicant specifically state the annual rainfall assumptions uses in the
     calculations. It is further recommended that any stormwater management plan be signed off by a
     Registered Professional Engineer Queensland (RPEQ).

Response
Covey Associates provide the following response:

In response to the Stormwater Management items requested by Seqwater we have included the
following information within the Stormwater Management Plan. The MUSIC modelling rainfall data
used to model pollutant reduction targets is from Cooroy Composite Station 1973 to 1983 as this is
the most continuous dataset available. The annual rainfall for each year has been included within the
SWMP as requested. Refer to Table 3: Annual Rainfall in the report.

The report demonstrates that the measures proposed to reach the WQOs identified in the
Environmental Protection (Water) Policy 2009. The proposed measures significantly exceeded the
required pollutant reduction targets by State Planning Policy and Noosa Shire Council to ensure the
best possible change of meeting the WQOs and prevent any potential adverse impacts on Lake
Macdonald. The daily loads estimated in MUSIC for TSS and TN are mean values and only marginally
