The above tables show that one blast results in 16/02/2012 were above 5mm/sec but below the 10mm/sec

criteria, which is allowable only for 5% of blasts in a 12 month period. The compliance against the overall 12

month period will be reported in the EPL Annual Return and Annual Environmental Management Report.

The blasting limits applying to Integra Coal are detailed in the tables below.

5.35.35.35.3 Noise Monitoring ResultsNoise Monitoring ResultsNoise Monitoring ResultsNoise Monitoring Results

Attended noise monitoring was undertaken by Spectrum Acoustics Pty Ltd on the 23rd February 2012. The

overall results were then analysed to determine the contribution of the mine and satisfaction or adherence

of the relevant noise criterion as specified in PA 08_0102.

Noise monitoring results from the surveys are presented in the table below.

A review of the above tables shows that noise levels monitored at all the above residences complied with

the criterion with the exception of a 3 dB exceedance at Richards during the night time measurement. This

receiver is in the Integra Coal noise acquisition zone and no complaints were lodged at the time of the

exceedance.

5.45.45.45.4 Water Monitoring ResultsWater Monitoring ResultsWater Monitoring ResultsWater Monitoring Results

Monthly surface water monitoring in the North Open Cut was conducted on the 22nd February 2012.

Surface water monitoring involves collecting water samples from a number of locations around site and

analysing for several physical and chemical parameters including pH, electrical conductivity and total

suspended solids.

Ground water monitoring in the North Open Cut was conducted on the 22nd February 2012 and involved

measuring the depth of each water source as well as analyzing for several physical and chemical

parameters including pH, electrical conductivity and TSS.
