4 Glossary Acoustic and vibration related terms: Acoustic Spectrum: A representation of a sound sample (usually short term) of the amount of energy or sound level per frequency. Ambient Noise: Ambient noise encompasses all sound present in a given environment, being usually a composite of sounds from many sources near and far. CONCAWE: noise modelling algorithm to predict the geographical propagation of noise from various noise sources CoRTN: Calculation of Road Traffic Noise (CRTN - ISBN , UK Department of Transport 1988) db(a): A unit of sound measurement which has frequency characteristics weighted so that it approximates the response of the human ear to sound waves ENMM: Environmental Noise Management Manual (RMS, 1) evdv: Is the estimated vibration dose for predicting an assessing human comfort exposure, measured as ms -1.7 Heavy Vehicle: A truck, transport or other vehicle with a gross vehicle weight above a specified level (for example: over 8 tonnes) L A1 : Descriptor used to define noise level which is exceeded 1 per cent of the time and is to the average of maximum noise levels L A1 (18hr) : Is the arithmetic average of the L 1(1hr) levels for the 18-hour period between 6 and hours on a normal working day. L A9 : Is the noise level that is exceeded 9 per cent of the measurement time. This parameter is commonly referred to as the background noise level L Aeq : Noise level that represents the energy average noise from the source during a specified time period, and is the equivalent continuous sound pressure level for a given period L Aeq(1hr) : The L eq noise level for the period from 7 am to 1 pm. L Aeq(9hr) : The L eq noise level for the period from 1 pm to 7 am. NCA: Noise Catchment Area. Grouping dwellings or receivers together in terms of similar noise environment. Noise barrier: Generally a wall or an earth mound that obstructs or restricts the passage of sounds waves from a noise source Noise Logger: A data logging (data and audio in some cases) which records noise. Usually used for unattended noise monitoring of background or ambient noise. NML: Noise Management Level as detailed in the NSW Interim Construction Noise Guideline. The NML is the noise goal for construction activities. Octave Bands: Sounds that contain energy over a wide range of frequencies are divided into sections called bands. A common standard division is in 1 octave bands identified by their center frequencies 31., 63,,, 1,, and Hz PPV: Peak Particle Velocity is is used to measure vibration through a solid surface. When a vibration is measured, the point at which the measurement takes place can be considered to have a particle velocity. This particle vibration will take place in three dimensions (x, y and z) and will usually end up back where it started. The Peak Particle Velocity is the maximum velocity that is recorded during a particular event. 389_1429 Page iii

5 RBL: Rating Background Level is the overall single figure background level representing each assessment period over the whole monitoring period. The RBL is used for determining the appropriate construction noise criteria. RNP: Road Noise Policy (OEH, 11) Sound Level Meter: An instrument consisting of a microphone, amplifier and data analysis package for quantifying and measuring noise. Sound Power Level (L w ): Sound power level or acoustic power level is a logarithmic measure of the sound power in comparison to a specified reference level. Sound Pressure Level (SPL or L p ): The level of noise, usually expressed in db(a), as measured by a standard sound level meter. VDV: Measured vibration dose value to indicate compliance with human comfort criteria Vibration: Vibration is a force which oscillates about some specified reference point. Vibration is commonly expressed in terms of frequency such as cycles per second (cps), Hertz (Hz), cycles per minute (cpm) or (rpm) and strokes per minute (spm). This is the number of oscillations which occurs in that time period. The amplitude is the magnitude or distance of travel of the force. 389_1429 Page iv

7 1. Introduction 1.1 Background In May 12, 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 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. At the time of preparing this report, the B9 paper machine has been operating for months and is currently operating at 9% production. Traffic within the site accesses via Botany Road and exits via McCauley Road as per the site traffic plan. There are no recent modifications or upgrades to the site layout or operations and the B7 paper machine building, scheduled for demolition, remains in situ. 1.2 Objective This report presents the details of operational licence conditions for noise measurements of the noise environment 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 194 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 : 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 Monitoring limitations The Orora monitoring survey relies on the cooperation of the local community to place loggers in key locations used in the compliance assessment, and Orora gratefully acknowledges this fact. While the noise surveys are scheduled to give residents enough notice of upcoming activities, the meteorological conditions during these surveys are not always favourable to the collection of data. In the most recent noise monitoring survey, long term monitoring was undertaken over a period of about one week at five of the six receiver locations due to construction activities at one of the properties. The receiver at R1 (see Figure 1) was monitored using a handheld sound level meter for a 1 minute period. The results from this location have been used in the assessment of noise levels and the compliance monitoring for the April period. 1.4 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 _1429 Page 1

8 Figure 1 Compliance monitoring locations R1 R2 R3 R4 R ORORA R6 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. 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 Murrabbin 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 ::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. 389_1429 Page 2

10 2. Operational noise monitoring Operational noise monitoring for the April 1 quarter has been incorporated into a six day monitoring survey. Due to access issues at receiver R1, noise loggers were deployed at five of the six representative locations and were operational for the duration of the survey. 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 BOM and the nearby automatic weather station located at Sydney Airport. The weather data was incorporated into the monitoring results to provide an indication of the quality of the data. Weather conditions for the monitoring period have been sourced from the Bureau of Meteorology (Sydney Airport) and plotted showing daily trends in wind speed which are presented in Figure 2. Figure 2 Wind speed and direction during monitoring period The plotted data indicates that the wind direction generally blew from between the north west to westerly directions affecting receiver locations in the south east and east of the Orora site. Stronger winds from the south and south-south west were also recorded for the monitoring period. These conditions typically favour an increase in the local noise environment with noise from sources such as Botany Road and Sydney Ports having a greater contribution to ambient noise levels. Wind speeds during the monitoring period included about % of measured velocities above m/s. 389_1429 Page 4

11 2.1 Monitoring results The purpose of the noise monitoring survey is to distinguish the noise emissions from the Orora site from the ambient noise environment Noise sources audible at the monitoring locations represent a large variety of acoustic influences from the area, which contribute to the overall local noise environment. The L Aeq noise level parameter that is the basis of the Orora operational criteria is therefore affected by all other extraneous noise sources in the area. Generally Orora operations have a noise profile consistent with plant and equipment that operate at more or less a steady state level and therefore there is little variability in noise emissions from the site. This type of noise emission is in contrast with other noise sources in the local area. To assist in identifying the site noise emissions, the L A9 statistical parameter has been considered in conjunction with the L Aeq noise level to provide additional information for assessment of impacts. The parameters of L Aeq and L A9 are used to provide information for comparison against the project criteria and the background noise environment. Noise levels at R1 are reported against attended monitoring only for the April monitoring period. A summary of the noise monitoring results is presented in Table 2. The results of long term monitoring have been graphed and are shown in Appendix A with areas of grey shading indicating adverse weather conditions recorded at the time of monitoring. The most recent round of compliance measurements presents details of the noise environment with the Orora site operational. Table 2 presents the assessment background noise levels and the rating background noise levels as well as the L Aeq, 1 minute for each assessment period. Due to the complex noise environment surrounding the Orora site, it is impractical to directly measure the contribution of Orora operations when monitoring at nearby receiver locations. Evidence of this is provided in earlier studies where the measured L Aeq noise levels at compliance locations are consistently above the EPL criteria, even when the Orora site is not operational. To further assist in the understanding of the local noise environment, additional graphs of the measured 1 minute results for the L Aeq and L A9 parameters have been plotted against time of day over the duration of the noise survey at each of the monitoring sites. These results demonstrate the spread of noise levels recorded at each site and are presented in Appendices B and C Discussion of results 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. Some activities such as truck movements (deliveries or pick ups) represent the more audible components of site activities however; these audible events tend to be infrequent. The ambient measured noise levels during the survey are consistently above the EPL criteria for day evening and night operations of the Orora site, but these levels are not wholly attributable to Orora s contribution. The measured levels indicate a significant variation in the short term noise levels at all sites throughout the day evening and night. The typically high noise levels measured during this survey period are expected to be influenced by the prevailing strong winds, predominantly from the south, south-west and westerly directions. 389_1429 Page

14 2.2 Comparison with previous monitoring An indicator of the contribution of Orora operational noise to existing noise levels may be made using background noise levels measured during survey. 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 during this time. The data in Table 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. The background noise levels from Table 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. Measurements recorded in July 14 (shaded) are representative of background noise levels resulting from adverse meteorology (temperature inversion), and are not typical of noise influences in the area.

15 3. Summary When the L Aeq measured noise levels during the April monitoring survey are compared to the criteria outlined in Orora s EPL No. 194, exceedances of the day, evening, and night time periods are indicated. Observations from previous studies indicate that the Orora B9 operations have only a minor contribution to the noise environment in the local area and therefore the measured noise levels do not solely reflect emissions from the site. The local meteorological conditions have a significant influence on the measured noise levels. The weather patterns recorded during the April survey generally favoured the propagation of noise from the direction of the major noise sources such as Orora, Botany Road, and Sydney Ports. These conditions influence the measured noise levels for the April period towards the residential locations to the east and north-east of the Orora site. It is expected that continued compliance monitoring will add more detail to the noise emission data collected in the area and enhance the current understanding of Orora s operational noise contribution. Currently, it is the opinion of the Jacob s representative, that Orora is operating within the noise goals outlined in its EPL. 389_1429 Page 9
