Dear David


Re:    Dust Deposition Monitoring Adjacent to Top Forestry Road –
       Proposed Poultry Growing Sheds, Ridgewood


Further to your request, MWA Environmental has undertaken dust deposition monitoring over a
three month period at two locations in proximity to the unsealed Top Forestry Road at
Ridgewood. The monitoring has been conducted to characterise the dust deposition rates from
existing vehicular traffic prior to commencement of the proposed poultry growing operations.

The monitoring and analysis has been undertaken in accordance with AS3580.10.1:2003
Methods for sampling and analysis of ambient air – Determination of particulate matter –
Deposited matter – Gravimetric method.

The monitoring locations were selected as representative of the typical minimum setback
distances from the edge of the Top Forestry Road to residential dwellings. It is noted that the
monitoring locations did not fully comply with Australian Standard siting guidance due to
constraints in relation to available setbacks from vegetation, however it was not considered to
affect the representativeness of the monitoring.

Dust monitoring locations A & B are shown on Figure 1.

The monitoring locations are described as follows:

       Location A:        Approximately 43 metres to roadway at Lot 20 on SP226606
                          Approximately 130 metres east of the poultry farm access to Top
                          Forestry Road

       Location B:        Approximately 20 metres to roadway at Lot 5 on RP838769
                          At the northwestern corner of the intersection of Top Forestry Road and
                          King Parrot Lane
