The previous licence conditions allowed the Linwood quarry to blast and maintain airblast readings under 120 dBL for 100% of the blasts. The new licence conditions required that 95% of the blasts registered an airblast reading of no greater than 115 dBL and all of the blasts must be under the 120 dBL airblast maximum limit.
