1. Introduction 1.1 Background In May 2012, ORORA Packaging began constructing the new B9 Paper Mill at its Botany site in Sydney, NSW. The New Paper Mill would replace the two existing papermaking machines (No. 7 and No. 8) at the site. The New Paper Mill is subject to operational noise conditions set out in Ministers Conditions of Approval (MCoA) (including subsequent modifications) and the Environment Protection Licence (EPL) No. 1594. As part of the EPL, there is a requirement to undertake quarterly monitoring at receivers surrounding the site to show compliance with set noise limits. Much of the detail in this report is unchanged since earlier compliance returns; as such the following information prior to Section 2 including noise limits and monitoring locations is for reference only. 1.2 Objective This report details the results of noise monitoring undertaken around the Orora site during a period of shut down and operations. The purpose of this document is to satisfy Condition M6.1 and M6.2 of EPL 1594 as follows: M6.1 The licensee must undertake noise monitoring at least once every three months to check compliance with the noise limits specified in Condition L4.1. M6.2 All monitoring required by this licence must be undertaken in accordance with Australian Standard 2659.1 1998: Guide to the use of sound measuring equipment Portable sound level meters, or any revisions of that standard which may be made by Australian Standards Authority, and the compliance monitoring guidance provided in the NSW Industrial Noise Policy. 1.3 Existing environment The site is located within a predominantly industrial area where residential properties located to its north and north east. The local noise environment beyond the Orora boundary varies throughout the day depending on traffic volumes and heavy vehicles using Botany Road, aircraft traffic, port traffic, local businesses on McCauley Road, and local traffic. Meteorological conditions also play an important role in the propagation of noise due to the site being located near the coast. These conditions include strong drainage flows for wind direction and also temperature inversions during the winter months. 1.4 Monitoring limitations Ambient noise at nearby receiver locations are the result, only in part, of Orora site operations. Direct monitoring of Orora noise emissions over several years has indicated that specific contribution from Orora cannot be provided with any certainty due to the multitude of audible sources adjacent to the site. In the most recent noise monitoring survey, long term monitoring was undertaken over a period of one week at six receiver locations. At one location, Receiver 3, the logger experienced a failure that resulted in some loss of data. The intermittent data collected during the week has been presented. 1.5 Receiver locations The EPL provides guidance on the location of six noise measurement sites to be reported for the quarterly monitoring. The position of these sites relative to the Orora site is presented in Figure 1-1. Page 1

R1 R2 R3 R4 R5 ORORA R6 Figure 1-1 Compliance monitoring locations Observations of the typical noise environment at each receiver location have been generalised to assist in the discussion and understanding of general noise impacts at these locations. Receiver 1: The receiver at this location has a large degree of acoustic shielding from local noise sources due to a boundary noise wall located on the opposite side of Australia Avenue. The noise environment at this location is heavily influenced by traffic on McCauley Street, Perry Street and Beauchamp Road. Local industrial noise from Raymond Avenue is also audible during the day and night time. Some construction work was in progress at the property during the monitoring period. Receiver 2: This receiver is located opposite the bottom apex of the Purcell Park on Australia Avenue. At this location residences have a clear line of sight to the paper mill. Noise walls have less effectiveness for the residences due to the large separation distances. Noise from port activities also has less shielding from the Orora site. Background noise levels are heavily dominated by road traffic noise from all sources. Receiver 3: These receivers are the closest and most exposed to general operational activities having less benefit of shielding from the boundary wall. At the end of Murrabin Avenue, the terrain is slightly elevated further reducing any attenuation from the noise wall. Receivers in Murrabin Avenue also have elevated background noise levels generated by Botany Road and Bunnerong Road. Receiver 4: The receivers at Partanna Avenue are physically the closest to the Orora site but have the benefit of significant shielding of operational activities from the B7 paper machine building and the No. 7 reel store. Road traffic noise contributes to background noise for this receiver. Receiver 5: Physically the furthest location from the Orora site, having a higher degree of influence from Botany Road, Bunnerong Road and the port. Noise from the Orora site is generally inaudible at this location although significant noise from the Orora site has been observed here during adverse meteorological conditions. Receiver 6: In this location receivers are well shielded from operational noise from the Orora site due to the presence of the redundant No. 7 and No. 8 paper machine buildings. Noise levels at this location are heavily influenced by local bird colonies, port noise, traffic on Botany road and traffic on Bunnerong Road. Page 2

2. Operational noise monitoring Operational noise monitoring for the April 2016 quarter has been incorporated into an eight day monitoring survey with automatic noise loggers deployed at the six representative locations. The measurements were taken using Acoustic Research Laboratories Ngara Type 1 noise loggers, set to record noise levels continuously over consecutive 24 hour periods at each location. Weather conditions during the noise survey were obtained from the nearby Automatic Weather Station (AWS) maintained by the Bureau of Meteorology at Sydney Airport. Weather conditions for the monitoring period have been plotted showing daily trends in wind speed which are presented in Figure 2-1. Figure 2-1 Wind speed and direction during monitoring period (20 28 April 2016) The plotted data indicates that the wind during the period of the noise monitoring survey generally prevailed from the north-west. When winds prevail from the north-west direction the local noise environment at the receivers is influenced by industrial facilities and the Orora site. During the monitoring period, 21% of winds were measured above 5 m/s. 2.1 Monitoring results The results of long term monitoring are shown in Appendix A with areas of grey shading indicating periods when the paper mill was not operating. The L Aeq and L A90 noise descriptors are used to provide information for comparison against the project criteria and the background noise environment. As noted above, monitoring at R3 produced intermittent data during the monitoring period due to the noise logger malfunctioning. 2.1.1 Discussion of results Table 2 summarises the measured noise levels during the April 2016 monitoring period. The total level of ambient noise measured during the survey was observed to exceed the EPL criteria for day, evening and night during both operational and shut-down periods. Page 4

Observations during the survey period suggest that the Orora site was occasionally audible in the general acoustic environment but was not the dominant noise source. The total level of L Aeq noise at receivers is contributed to by relatively constant sources such as traffic as well as intermittent sources such as birds, aircraft, construction noise and vehicle movements on local roads. The Orora site has a noise profile consistent with plant and equipment that operate at more or less a steady state and therefore has little variability in noise emissions. The constancy of noise emitted from the Orora premises affords the opportunity to quantify its emission using the L A90 statistical parameter, which has been considered in conjunction with the L Aeq noise level when assessing compliance of the Orora site. It has previously been shown to be impractical to directly measure the contribution of Orora operational noise emissions when monitoring at nearby receiver locations. Evidence of this fact is provided where the measured L Aeq noise levels are consistently above the EPL criteria, even when the Orora site is not operational. Page 5

2.2 Comparison with previous monitoring Quantification of the contribution of Orora operational noise to the total level of ambient noise may be made using background noise levels measured during both shutdown and operational conditions. During the night time period fewer extraneous noise influences are present providing lower overall noise levels in the area. Under these conditions constant noise sources such as Orora operations are more likely to be apparent in the background noise levels measured during this time. The data in Figure 2-2 and Figure 2-3 provides a chronological progression of noise data for both shutdown and operational conditions over several years. These results demonstrate the degree of variability in the noise environment at these locations due to seasonal and local influences. During the April 2016 monitoring period the paper machine was shut-down from between 6:30am 21 April to 2:15am 22 April 2016. The background noise levels from Figure 2-2 and Figure 2-3 are not directly related to the L Aeq criteria; however, they provide an indication of the increase in background environmental noise levels during periods of activity within the Orora site. The results show that the monitoring conducted in April is consistent with the monitoring done in other periods. Page 8

3. Summary All previous quarterly noise monitoring surveys have demonstrated that the total ambient L Aeq noise level exceeds the EPL criteria for day, evening, and night periods whether the site is operational or in a shutdown. The most recent results for the April 2016 monitoring period indicates that an exceedance of the EPL criteria is apparent at all the representative receiver locations. These exceedances are not attributable to the operations of the B9 paper mill. From the April 2016 monitoring the following conclusions may be drawn. The most recent noise monitoring results indicate that the measured L A90 noise levels from all sources (including Orora) are consistent with monitoring from other corresponding periods on an annual basis. The meteorological conditions during the monitoring period were typically favourable to the propagation of noise to residences from the north-western industrial sources and the Orora B9 paper mill. These weather patterns typically generate an increase in noise impacts at receiver locations. The ambient noise environment in the local area is a product of the combined influence of all noise sources within the Port Botany area including the Orora site, confirming again that direct measurement of specific noise emissions is not possible. Based on the current monitoring data and using the L A90 background noise results as an indicator of noise influences from constant noise sources such as the Orora site, the current noise contribution from operations of the B9 plant are expected to be generally compliant with their EPL noise limits during operational periods.
