1 INTRODUCTION 1.1 Assessment Requirements Helensburgh Coal Pty Ltd (HCPL) owns and operates the Metropolitan Colliery, located approximately 30 kilometres (km) north of Wollongong in New South Wales (NSW). The Metropolitan Colliery has a long history that extends back to the 1880s and longwall mining commenced at the Metropolitan Colliery in 1995. The mine currently produces approximately 1.5 million tonnes (Mt) of coking coal per year. HCPL proposes an expansion of the Metropolitan Colliery raw coal production and upgrade of the Coal Handling and Preparation Plant (CHPP) to increase saleable coal production which is referred to as the Metropolitan Coal Project (the Project). Heggies Pty Ltd (Heggies) has been engaged by HCPL to evaluate and assess the potential noise impacts associated with the Project. The assessment has been guided by the NSW Department of Planning (DoP) Environmental Assessment Requirements (EARs) which require consideration of potential construction, operational and on-site and off-site road and rail noise and vibration impacts. In accordance with the DoP requirements, the major sources of noise emissions may be grouped as follows: On-site Intrusive Noise Assessment Surface construction works would be undertaken intermittently over a period of up to five years, generally during daytime hours. Construction activity associated with the CHPP upgrade and establishment of a backfill paste plant would coincide with the end of Year 3 operations and have been assessed cumulatively with other on-site operational noise sources. Project operations in Year 15 coincide with peak coal production and have also been assessed. The NSW Industrial Noise Policy (INP 2000) provides non-mandatory procedures for setting acceptable LAeq(15minute) intrusive (and LAeq(period)) amenity noise levels for various receiver areas and guidelines for assessing noise impacts from on-site stationary noise sources. Cumulative Industrial Noise Amenity The INP also provides non-mandatory cumulative noise assessment guidelines that address existing and successive industrial development by setting acceptable (and maximum) cumulative LAeq(period) amenity levels for all industrial (ie non-transport related) noise in a receiver area. Note, the INP does not set acceptable cumulative LAeq(15minute) intrusive criteria for all industrial noise sources in a receiver area, but rather seeks to control cumulative noise via its amenity criteria. The existing Metropolitan Colliery is the only significant industrial development located to the east of the Helensburgh Township (excluding the municipal tip located to the north-east of the Metropolitan Colliery) and therefore the potential for cumulative industrial noise is minimal. Blast Emissions Underground Blasting: Use of explosives is not required for existing or proposed general underground coal mining. Occasionally the existing continuous miner encounters geological structures that are broken up by using very low explosive masses. The NSW Department of Environment and Climate Change’s (DECC’s) “Assessing Vibration: A Technical Guideline” dated February 2006 does not address blast-induced effects. However, Australian Standard AS 2187.2 - 2006 “Explosive - Storage and use Part 2: Use of Explosives - Appendix J” does provide guidance on relevant procedures for assessing the blast-induced noise and vibration effects on buildings and their occupants.
