Appendix F1 Report 10-5055-R1 Page 1 of 4 BACKGROUND NOISE MONITORING RESULTS - DECEMBER 2006 Overview of Methodology A noise monitoring programme was commenced in December 2006 to quantify background noise levels (ie all noise sources) and to estimate industrial noise only (ie. in the absence of transport, natural and domestic noise). Four unattended noise loggers were positioned at representative residential localities adjacent to the Metropolitan Colliery site commencing Monday 29 December 2006 for a period of 10 days. In order to supplement the unattended logger measurements and to assist in identifying the character and duration of the noise sources, operator-attended daytime, evening and night-time surveys were also conducted at all four logging locations. The background noise monitoring programme was implemented in accordance with AS 1055-1997 “Acoustics-Description and Measurement of Environmental Noise” and the NSW Industrial Noise Policy (INP) 2000. 3.2 Instrumentation and Measurement Parameters Unattended Monitoring and Operator-Attended Surveys All acoustic instrumentation employed throughout the noise monitoring programme has been designed to comply with the requirements of AS 1259.2-1990, “Sound Level Meters” and carries current National Association of Testing Authorities (NATA) or manufacturer calibration certificates. A description of instrumentation, designated type and serial numbers is shown in Table 1. Table 1 Acoustic and Meteorological Instrumentation Schedule ID Location Noise Logger Weather Logger Serial Number 016 16 Oxley Place, Helensburgh Rear property boundary n/a 16-004-034 P55A 55A Parkes Street, Helensburgh Rear of property n/a 194591 P83 83 Parkes Street, Helensburgh Rear fence boundary n/a 16-203-506 F19 19 Old Farm Road, Helensburgh Front of property n/a 193410 n/a Mine Managers Residence n/a Front of property TBA All instrumentation was programmed to record continuously the noise exceedance levels in 15 minute intervals including the LAmax, LA1, LA10, LA50, LA90, LA99, LAmin and the LAeq. Instrument calibration was conducted before and after each measurement survey, with the variation in calibrated levels not exceeding ±0.5 dBA. Weather Station Local meteorological data was obtained from a portable Automatic Weather Station located at the Mine Managers Residence at the eastern end of the Colliery site. The AWS recorded wind speed and direction, air temperature, relative humidity and rainfall in 15 minute intervals. 3.3 Unattended Background Noise Monitoring Results The unattended background noise logger data from each monitoring location, together with the on-site weather conditions were analysed on a daily basis. The statistical noise exceedance levels (LAN) are the levels exceeded for N% of the interval period. The LA90 represents the level exceeded for 90% of the interval period and is referred to as the average minimum or background noise level. The LA10 is the level exceeded for 10% of the time and is usually referred to as the average maximum noise level. The LAeq is the equivalent continuous sound pressure level and represents the steady sound level which is equal in energy to the fluctuating level over the interval period.

Appendix F1 Report 10-5055-R1 Page 2 of 4 BACKGROUND NOISE MONITORING RESULTS - DECEMBER 2006 Prior to further analysis, the background noise data from each location which correlated with periods of unstable weather (eg rainfall greater than 0.5 mm or wind speed greater than 5 m/s) were discarded. The acceptable background noise data was then processed in accordance with the INP “Appendix B - Applying the Background Noise Policy” to derive the Monday to Sunday background noise levels presented in Table 2.
