5. Mobile Crusher Plant 24 Hour Trial Noise Monitoring Results Date: Wednesday 18th March 2009 12.30am to 4.30am

6. Noise Abatement Initiatives  Noise monitoring program at Penrice Rd residents  Trial delayed start Train loading – 0730am start Monday to Friday – 0800hrs start Saturday and Sunday  Two trains on Thursday 9 th and Friday 17 th for Easter and Vintage Festival  Two Mobile Crushers removed from site – one located Council Pit and one on Brighton Lite Hill  Sales Yard 2 day trial 2 nd & 3 rd April oNo trucks to enter site prior to 0600hrs oNo loaded truck to leave site prior to 0630am  Investigate possibility to preload Nexy trucks PM on site, store off site for delivery AM next day

7. Tarp survey Letters to freight companies issued requiring tarping compliance by 30 th April Tarping survey conducted of trucks exiting site on 30/03/09, it was found;  89% of the trucks used the truck wash.  Of the 310 trucks exiting the site 80% of them, 247 trucks, were fitted with tarps.  Of those 247 trucks 63% used there tarp.  37% of trucks that could tarp, didn’t. This is a vast improvement from the last survey conducted and with further implementation we shall see all trucks tarping. Freight companies were recorded and non compliant drivers have been notified of the requirements to tarp.

8. Tarp Letter TARPING OF TRUCKS LEAVING PENRICE MINE SITE An EPA licence condition for Penrice Quarry & Mineral (PQM) is for all truck movements leaving the Quarry to be tarped. Penrice is a community caring business and is committed to eliminating any dust issues that may impact our neighbours. The tarping of vehicles is seen to be a step that is required to eliminate dust emission from vehicles leaving the Quarry. It is now PQM policy for all vehicles fitted with a tarp to comply with this by the end of April 2009. Should a tarp need to be installed to a vehicle, PQM require this to be undertaken to comply with this policy by the 30th June 2009. Regards Penrice SODA PRODUCTS PTY LTD Andrew Maynard Sales Manager – Quarry & Mineral
