Throughout the September 2017 source noise level measurements metal fabrication activities within the
Allstar Metal Fabrication building were representative of normal activities and all of equipment
associated with the highest potential noise sources was being operated.

Subsequent to the installation of a new guillotine and metal folding machine, a further source noise
assessment was conducted on Wednesday 28 March 2018, with the following results:

        Metalmaster guillotine, model number MG-840, serial number 1711042, at 3 metres from the
         guillotine inside the workshop:

              o    cutting composite sheet 2 mm thick:
                         73.5 dB(A) LAeq,T;
                         81.7 dB(A) LA1,T;
                         77.8 dB(A) LA10,T;

              o    cutting 3 mm thick aluminium checker plate:
                         78.3 dB(A) LAeq,T;
                         85.9 dB(A) LA1,T;
                         82.8 dB(A) LA10,T

        Metalmaster hydraulic NC pan folder, model number PB-820L, serial number 1709034, at 2
         metres inside the workshop:

              o    folding metal sheet 2mm thick:
                         67.0 dB(A) LAeq,T;
                         68.5 dB(A) LA1,T;
                         67.2 dB(A) LA10,T.
