Executive SummaryAECOM have been engaged by Penrice to conduct a survey of the existing mobile and fixed plant at the Penricemine/quarry to develop a detailed noise model for the mine/quarry. This assessment is for onsite noise sourcesonly and specifically excludes noise associated with trucks entering and leaving the mine/quarry on public roads.

A site survey was conducted by AECOM on 9 and 11 July, 2009. During this time, all plant was measured, withthe exception of the mobile rock breaker, which was measured at a later date.

The Penrice mine/quarry site has a number of different development plan localities surrounding it. This leads to avariety of noise criteria under the South Australian Environment Protection Authority Environment Protection(Noise) Policy 2007.

Based on the calibrated noise model and current operations, Penrice are compliant with criteria provided by theSouth Australian Environmental Protection Agency Environment Protection (Noise) Policy 2007 undermeteorological conditions conducive to the propagation of noise from the mine/quarry.

However, due to community concerns Penrice advise that they will reduce noise emissions from the mine/quarry.

In order to reduce noise emissions from the mine/quarry, we make the following recommendations (prioritised inorder of treatment):

1) Treatment of aggregate plant:- Install enclosure (or acoustic equivalent), with acoustic insulation over the first and second vibrating

screens associated with the aggregate plant- Enclose bottom of the aggregate plant feed enclosure- Construct a shed with fast-action roller doors around the opening for the aggregate plant crusher

2) Install a horizontal barrier over the train loading facility with acoustic insulation installed on the underside3) Extend train loading barrier by 10 metres to the south4) Clad vibrating screen structure for train loader

We have applied a higher priority to reducing night time noise levels over train loading during the daytime period.

These measures are expected to result in reductions in night time noise levels, and annoyance associated withimpact noise during train loading.

Noise levels during the daytime period are generally from a variety of sources and not controlled by a singlesource. Treatment of some sources is not likely to result in a significant decrease in daytime noise levels.

1.0 IntroductionThe Penrice mine/quarry located in the township of Penrice is operated by Penrice Soda Holdings Ltd. Due tocommunity concerns regarding noise emissions from the mine/quarry, AECOM have been engaged by PenriceSoda Holdings Ltd. (Penrice) to create a noise model of the existing site and noise sources, and advise onappropriate measures to reduce the overall noise emissions from the mine/quarry. This assessment is for onsitenoise sources only and specifically excludes noise associated with trucks entering and leaving the mine/quarry onpublic roads.

This report presents the findings of our study on the existing site conditions, and the likely outcomes fromtreatments proposed through discussions with Penrice.

Definitions for acoustic terms used in this report are attached as Appendix A.

2.0 BackgroundThe Penrice mine/quarry is located near the township of Penrice in the Barossa Valley. The mine/quarry isbounded on the southern side by the township of Penrice, with residences located on Salem Road and PenriceRoad in the township of Penrice.

On the western and northern side, the mine/quarry site is bounded by agricultural industry, including vineyardsand broadacre farming. There are a number of detached dwellings located in this area, with generally lowdensity.

Under the Barossa Council Development Plan, the Penrice mine/quarry is located within the Extractive IndustryZone. The Penrice mine/quarry site is adjacent four zones containing residences. Figure 1 shows thedevelopment zones from the Barossa Council Development Plan in the area around the Penrice mine/quarry.

3.0 Noise criteriaThe Penrice mine/quarry is located in the Extractive Industry zone. There are residences in four different zonesadjacent to the Extractive Industry zone. Noise criteria for each zone are presented in Table 1. Details on theselection of noise criteria are attached in Appendix C.Table 1: Noise criteria for Penrice mine/quarry in zones adjacent the mine/quarry site

Development Plan Zone Noise EPP land use category Noise criteria in dB(A)Day Night

Rural (Valley Floor) Rural Industry 64 55Rural (Moculta) Rural Industry 64 55Rural Living (1) Rural Living 59 50Residential Residential 61 53

Under the Noise EPP, the measured source noise levels must be adjusted by the following amounts if the noisesource contains the amplitude modulating, tonal, impulsive or low-frequency characteristics:

noise source contains 1 characteristic, add 5 dB(A) noise source contains 2 characteristic, add 8 dB(A) noise source contains 3 or 4 characteristics, add 10 dB(A)

As there is variability in criteria, as well as the character and type of noise sources over the mine/quarry site, thesurrounding areas have been broken up based on the location of the residence to group properties with exposureto similar sources.

Properties have been grouped in the following catchments:

South: properties located in the Residential and Rural Living (1) zones on Penrice and Salem Roads andRowland and Murdock Streets

North-east: properties located in the Rural (Moculta) Zone, including properties on Salem and KalimnaRoads

North-west: properties located in the Rural (Valley Floor) Zone, including properties on Stockwell Road West: properties located on Penrice Road

Figure 2 shows residences located near the Penrice mine/quarry. Table 2 gives Noise EPP criteria for theidentified residences.Table 2: Summary of noise criteria for assessed receivers

4.0 Mine/quarry noise survey and calibrationA survey of the existing noise sources at the mine/quarry site was conducted on 9 and 11 July, 2009. During thissurvey, noise measurements of all mobile and stationary plant were taken, with the exception of the mobile rockbreaker which was undergoing off-site repairs. Noise levels from the mobile rock breaker were measured on 23July 2009 after repairs had been completed.

Mobile plant measured during the survey included:

60 tonne and 90 tonne haul trucks Front end loaders Tracked excavators Grader Tracked bulldozer Mobile rock drills Skidsteer Mobile crusher Mobile rock breaker Mobile vibrating screen

Fixed plant included:

Glass sand compressor shed Train loader, conveyor and vibrating screens associated with train loading Aggregate plant crusher and vibrating screens Tertiary building Primary crusher Primary screen building Stacker for train stockpiles Pugmill Transfer station

Measured noise levels and sound power levels1 used for noise modelling are attached as Appendix B.

Noise levels for individual sources were calibrated using measurements from plant while undergoing standardoperations.

Measurements were taken at nine locations around the Penrice mine/quarry boundary on 11 July 2009 to use forvalidation of the noise model. The median difference between measured and predicted noise levels was+0.5 dB(A) (i.e. the model over predicted by 0.5 dB(A)) with a standard deviation of 1.5 dB(A). Predicted noiselevels at the boundary were within ±2 dB(A) of measured levels. This is considered to be a good correlationbetween predicted and measured noise levels.

Noise level predictions for validation were done using the CONCAWE2 prediction methodology, which takes intoaccount meteorological conditions and windspeed during the times of measurement.

5.0 Assessment

5.1 Existing noise environmentNoise levels at residences around the mine/quarry site have been predicted under worst case meteorologicalconditions (i.e. most conducive to increased noise levels at the receiver) and compared to the relevant noisecriteria from the Noise EPP.

Where noise is likely to be from a source containing annoying characteristics, such as impulsive noise from rockdrills, adjustments have been made as required under the Noise EPP.

The following table presents a summary of the highest predicted noise levels around the site for the noisecatchments.Table 3: Highest predicted noise levels in dB(A) at residences surrounding Penrice mine/quarry site

Catchment Daytime Night timeCriteria Noise level Criteria Noise level

North-west – normal 64 54 55 51West – train loading 64 59(4) 55 N/AWest – normal 64 55 55 44Notes:

(1) Noise level has been adjusted by 5 dB(A) due to impulsive characteristics from rock breaker attached to the primary crusher

(2) Noise level has been adjusted by 5 dB(A) due to impulsive characteristics from the mobile rock breaker

(3) Noise level has been adjusted by 5 dB(A) due to impulsive characteristics from rock drill

(4) Noise level has been adjusted by 5 dB(A) due to impulsive characteristics from loading of train carriages

Based on the calibrated noise model, it is likely that Penrice are compliant with criteria provided by Noise EPPunder meteorological conditions conducive to the propagation of noise from the mine/quarry.

Noise contours for the area under worst case meteorological conditions during the following three operationalscenarios are attached in Appendix D:

typical daytime operations (Map D-1) typical night time operations (Map D-2) daytime operations during train loading. (Map D-3)

It should be noted that the contours have not been adjusted due to noise characteristics.

5.2 Noise source identificationThree main operational scenarios were identified for the Penrice mine/quarry: daytime operation, night timeoperation and daytime train-loading operations. Noise levels for each source under meteorological conditionsmost conducive to increased noise levels at receivers have been predicted for the various scenarios.

5.2.1 Daytime operation

During daytime operation, all fixed and mobile plant are normally operating, with the exception of the train-loadingplant and associated screens and conveyors.

Noise predictions from all operational plant have been predicted for all properties adjacent the Penrice plant.

In order to quantify which plant are contributing the greatest to the majority of properties, the logarithmic averageof noise levels for each source have been predicted to give a weighted ranking. A summary of the top tenweighted rankings for the entire mine/quarry site during daytime operations is presented in Table 4.Table 4: Top ten noise source weighted rankings in dB(A) during daytime operation

Rank Source Weighted rank1 Tertiary building 422 Primary screen building 423 Mobile rock breaker 404 Vibrating screens associated with aggregate plant 405 Rock breaker operating on primary crusher 396 Aggregate plant crusher 387 Front end loader loading aggregate plant 378 90 tonne haul trucks 369 Tracked dozer 35

10 Transfer platform from primary crusher 35

As can be seen from the table, daytime noise levels around the mine/quarry site are a combination of similarstrength noise sources. Treatment of one noise source is not expected to provide significant benefit to themajority of residences around the mine/quarry, although it may provide benefit to those residences which aremore exposed to that source.

Tables 5 to 8 present the top five weighted rankings for properties in each catchment.Table 5: Top five noise source weighted rankings in dB(A) during daytime operation in the southern catchment

Rank Source Weighted rank1 Tertiary building 482 Primary screen building 483 Limestone stacker 454 Primary crusher rock breaker 445 Transfer platform from primary crusher 40

Noise levels in the southern area are likely to be highly variable, with noise levels from mobile plant varying as theplant moves around the site. Noise levels from the rock breakers will be highly impulsive and require adjustmentunder the Noise EPP.

Noise levels in the north-eastern area are also likely to be highly variable, and controlled by mobile plant. As plantmoves around the site, noise levels are expected to rise and fall. Noise levels may contain amplitude modulatingor impulsive characteristics from mobile plant or the rock drill and adjustment may be required under the NoiseEPP.

Noise levels in the north-western and western catchments are likely to be fairly steady and broadband in nature,and it is unlikely that adjustments under the Noise EPP will be required.

5.2.2 Night time operation

During night time operation, the majority of fixed and mobile plant is not operating, although some items willremain in operation until midnight. Some of the non-operating plant may be used in emergency situations or ifdemand requires it. Based on information provided by Penrice of plant that operates at night, Table 9summarises the top ten noise sources by weighted rank for all nearby residences.Table 9: Top ten noise source weighted rankings in dB(A) during night time operation

Rank Source Weighted rank1 Aggregate plant vibrating screens 402 Aggregate plant crusher 383 Front end loader loading aggregate plant 374 Front end loader picking up material for aggregate plant 315 Contractor rock drill 296 Front end loader working in pit 287 Mobile crusher 288 Pugmill 279 Mobile rock breaker 23

10 Front end loader loading trucks 22

As seen in Table 8, night time noise levels are controlled by the aggregate plant, with noise from the vibratingscreens, crusher and loading of the crusher noticeably higher than other noise sources.

Weighted rankings for the catchments defined in Section 5.1 are presented in Tables 10 to 13.

Night time noise levels are controlled in all catchments except the north-eastern catchment by noise from theaggregate plant, including crusher noise, vibrating screens and loading of the crusher.

Mitigation of noise from the aggregate plant is likely to result in noticeable reductions in night time noise levels forthe majority of residences adjacent the Penrice mine/quarry.

5.2.3 Train loading

During train loading operations, noise levels at properties located in the western catchment are controlled bynoise from the train loader. Train loading typically occurs between 8am and 11am daily, with most fixed andmobile plant also in operation. Table 14 presents the top five noise sources by weighted rank during train loadingfor all properties.Table 14: Top ten noise source weighted rankings in dB(A) during train loading

Rank Source Weighted rank1 Train loader 442 Tertiary building 423 Primary screen building 424 Mobile rock breaker 405 Vibrating screens associated with aggregate plant 40

Train loading is the controlling source during operation, primarily due to levels in the western catchment abovethose for typical daytime operations by up to 9 dB(A).

Mitigation of noise from train loading would result in noticeable reductions in noise levels in the westerncatchment.

6.0 Conceptual noise mitigationSection 5.2 showed that during night time operations, noise levels around the plant are generally controlled by theaggregate plant and the vibrating screens associated with it. Treatment of the aggregate plant would producenoticeable reductions in night time noise levels at nearby residences.

During the train-loading, activities associated with the train loader control noise levels around the plant.Treatment of the train loader is likely to result in reducing the annoying characteristics of noise from Penriceassociated with impacts of limestone as it is loaded in wagons.

6.1 Aggregate plantBased on discussions with Penrice, it is proposed to provide mitigation to noise from the aggregate plant. Thiswould include providing enclosures to vibrating screens 1 and 2. Vibrating screen 3 is more than 10 dB(A) quieterthan screens 1 and 2, and does not significantly contribute to the overall noise level at residences. It is alsoproposed to close off the bottom of the aggregate plant where it is currently open as seen in Figure 2.

Figure 3: Openings at the bottom of the enclosure around the aggregate plant crusher

Where there is an opening at the top of the aggregate plant enclosure for a front end loader to supply aggregateto the crusher, it is proposed to provide an airlock with a shed and automatic roller doors. During night timeperiods it is proposed that the front end loader would enter the air lock with the roller door closing behind toensure that unloading noise and noise from the crusher is reduced. During the day, the roller doors would remainopen to allow for access.

The sheds surrounding the vibrating screens should be constructed from Colorbond or equivalent with acousticlining such as 100 mm thick Tontine AcoustiSorb 2 (similar to the construction of the existing aggregate plantcrusher enclosure). Roller doors should be fast acting automatic doors, such as 4 mm thick PVC MTI See-ThruRoll-Fast door or acoustic equivalent.

P:\60099270\4. Documents\60099270-A9K01RP-1.docxRevision 1 - 2 March 2010 11

The effects of these treatments would be a noticeable reduction in night time noise levels for the majority ofresidences located near the mine/quarry.

Daytime noise levels would remain relatively unchanged for most residences.

Table 15 presents some typical noise levels for worst case meteorological conditions at receivers adjacentPenrice during daytime and night time operations with the proposed mitigation measures in place (excluding trainloading, see Section 6.2).Table 15: Predicted noise reductions in dB(A) achieved with proposed mitigation measures in place under worst case meteorological

Daytime noise levels are not likely to be noticeably reduced around the majority of the mine/quarry. Night timenoise levels on the western side of the mine/quarry are likely to be significantly reduced, with noise levels atreceivers on Penrice Road expected to experience a significant reduction in night time noise levels.

6.2 Train loadingUpgrading the existing train loading barrier in order to reduce noise emissions during train loading has beenproposed through discussions with Penrice.

The proposed noise mitigation measures include providing horizontal barriers above the train loader forapproximately 12 metres in each direction. In addition to this, we recommend that the existing barrier beextended by 10 metres at the southern end to reduce noise leaking around the end of the barrier.

The horizontal barrier should be constructed from Colorbond or equivalent, with acoustic lining installed on theunderside of the barrier, such as 100 mm thick Tontine AcoustiSorb 2.

It is not expected that overall noise levels will be significantly reduced during train loading activities due to othernoise from screens associated with train loading, however there will be a noticeable reduction in impact noiseassociated with limestone being loaded into the wagons and noise at nearby residences would be more steadyand broadband similar to typical operations. This would reduce the annoying character of noise at nearbyresidences and lead to not applying adjustments for impulsive noise.

This would produce a 5 dB(A) reduction in the adjusted noise level when assessed under the Noise EPP.

In order to produce further reductions from train loading, noise attenuation measures from the vibrating screenslocated behind the train loader would be required. Cladding of the train loading vibrating screens in Colorbond orequivalent would provide up to 4 dB(A) reduction in noise levels at the closest residences during train loading.

6.3 Noise Contours – With MitigationNoise contours have been prepared for four noise mitigation scenarios and attached in Appendix D, as follows:

noise mitigation to aggregate plant only- daytime operation (Map D-4)- night time operation (Map D-5)

noise mitigation to train loader only, daytime operation with train loader (Map D-6) noise mitigation to aggregate plant and train loader, daytime operation with train loader (Map D-7).

7.0 RecommendationsNoise levels at residences surrounding the Penrice mine/quarry are predicted to achieve criteria from the SouthAustralian Environmental Protection Agency Environment Protection (Noise) Policy 2007 under worst casemeteorological conditions during both day and night time, including during train loading.

In order to reduce noise emissions from Penrice, we make the following recommendations (prioritised in order oftreatment):

1) Treatment of aggregate plant:- Install enclosure (or acoustic equivalent), with acoustic insulation over the first and second vibrating

screens associated with the aggregate plant- Enclose bottom of the aggregate plant feed enclosure- Construct a shed with fast-action roller doors around the opening for the aggregate plant crusher

2) Install a horizontal barrier over the train loading facility with acoustic insulation installed on the underside3) Extend train loading barrier by 10 metres to the south4) Clad vibrating screen structure for train loader

These measures are expected to result in reductions in night time noise levels, and annoyance associated withimpact noise during train loading.

Appendix A Acoustic terms

A-weighted The A-weighting scale is designed to adjust the absolute sound pressure levels tocorrespond to the subjective response of the human ear.

dB(A) Unit for A-weighted overall sound pressure level measured in decibels re 20 Pa.

Leq The Leq is defined as the equivalent noise level and is the energy averaged noise levelover the measurement period. This measure is commonly used by legislation whensetting limits for environmental noise.

Lmax The maximum noise level during the measurement period.

Sound PressureLevel

The Sound Pressure Level can be directly measured using a sound level meter and for agiven noise source varies with distance to the source. Measured in dB, referenced to20 Pa.

Sound PowerLevel

The Sound Power Level is a measure of the acoustic energy produced by a source and ismeasured in dB relative to 10-12 Watts. The sound power level is not directly measurableusing a sound level meter and is independent of the distance from the source. It iscalculated from the sound pressure level, taking into account the distance of themeasurement from the noise source and the size of the noise source.

Appendix C Noise criteria selectionClause 25 of the Environment Protection Act 1993 provides the following general environmental duty:

“A person must not undertake an activity that pollutes, or might pollute, theenvironment unless the person takes all reasonable and practicable measures toprevent or minimise any resulting environmental harm.”

The Environment Protection (Noise) Policy 2007 sets noise goals that compliance with will satisfy the generalenvironmental duty. These noise goals are based on the uses principally promoted by the relevant DevelopmentPlan (The Barossa Council Development Plan).

The indicative noise factors from the Noise EPP for determining noise goals are presented in Tables 19 and 20(labelled Tables 1 and 2 in the Noise EPP). Indicative noise factors are selected from Table 1 when both thenoise source and noise-affected premises fall within one of the two specified land uses. The day period refers tothe time between 7am and 10pm, and the night period from 10pm to 7am.Table 19: Table 1 (subclause (1)(a)) from the Noise EPP

The Penrice mine/quarry is located in the Extractive Industry zone under The Barossa Council Development Plan.The measurement locations are located in the following zones:

Location 1 — Rural (Valley Floor) Zone Location 2 — Residential Zone Location 3 — Rural Living (1) Zone Locations 4 to 7 — Rural (Moculta) Zone Locations 8 to 10 — Rural (Valley Floor) Zone

The Development Plan provides the following objectives for the assessed zones.

Extractive Industry Zone

Objective 1: A zone primarily for mining operations protected from incompatible development.Objective 2: Protection of existing watercourses and vegetation.Objective 3: Mining operations undertaken in a manner which minimises environmental and visualimpact.

Based on these objectives, we believe that the Extractive Industry Zone would be classified as Special Industryunder the Noise EPP.

Residential Zone

Objective 1: A zone primarily for residential use with a range of dwelling types to accommodate variedsocio-economic needs.Objective 2: A zone accommodating educational uses and other non-residential activities which are smallin scale, benign in external impact and serve the needs of the local community.

P:\60099270\4. Documents\60099270-A9K01RP-1.docxRevision 1 - 2 March 2010 C-2

Objective 3: Safe, pleasant, convenient and distinctive living environments.Objective 4: Medium density residential development, including aged-persons accommodation, in closeproximity to centres and other suitable locations where the established character of the area is not likely tobe adversely affected.Objective 5: Development consistent with the Desired Character Statement for each town.Objective 6: Maintenance and and enhancement of:

(a) a substantial residential character and amenity;(b) areas of distinctive historical character; and(c) natural or cultural features, including stands of trees, landscaping, historical buildings and

watercourses.Objective 7: Reduction of the impact of established non-residential uses on the amenity of residentialareas.

Based on these objectives and the Town Character Statement for Angaston, we believe that the Residential Zonewould be classified as Residential under the Noise EPP.

Rural Living (1) Zone

Objective 1: A zone primarily for low density residential use in association with a range of low intensitysemi-rural and rural activities, including low-scale home based industry.Objective 2: Maintenance of an open, semi-rural and rural character which contrasts with the built-upareas and rural land.Objective 4: Development having a high standard of appearance, by reason of design, use, externalmaterials, colours, siting and landscaping, to blend with the semi-rural and rural character of the locality.

We believe Rural Living (1) Zone would be classified as Rural Living under the Noise EPP.

Rural (Moculta) Zone

Objective 1: A zone primarily for broadacre farming and winery development in appropriate locations.Objective 2: Preservation of rural land and landscape character by limiting additional dwellings and non-agricultural development.Objective 3: Winery facilities only where the character and function of broadacre farming areas are notadversely affected.Objective 4: Existing winery and industrial uses only expanded in association with improvements to theamenity, visual impact, site access and environmental protection standards of activities.

Rural (Valley Floor) Zone

Objective 1: A zone primarily for viticulture and associated winery, horticulture and farming uses.Objective 2: Preservation of rural land and landscape character by limiting additional dwellings and non-agricultural development.Objective 3: Winery and small-scale tourist facilities only where the character and function of viticultureactivities are not adversely affected.Objective 4: Existing winery and industrial uses only expanded in association with improvements to theamenity, visual impact, site access and environmental protection standards of activities.

Based on the objectives of the Rural (Moculta) Zone and Rural (Valley Floor) Zone, we believe these zones wouldboth be classified as Rural Industry under the Noise EPP.

As residences are not located inside a General Industry or Special Industry area, Table 2 must be used to selectindicative noise factors. Table 2 gives the following indicative noise factors for the source and measurementlocations:

Extractive Industry Zone (Special Industry) — 70 dB(A) day, 60 dB(A) night Rural (Valley Floor) Zone (Rural Industry) — 57 dB(A) day, 50 dB(A) night Rural (Moculta) Zone (Rural Industry) — 57 dB(A) day, 50 dB(A) night Residential Zone (Residential) — 52 dB(A) day, 45 dB(A) night Rural Living (1) Zone (Rural Living) — 47 dB(A) day, 40 dB(A) night

P:\60099270\4. Documents\60099270-A9K01RP-1.docxRevision 1 - 2 March 2010 C-3

From Clause 9 of the Noise EPP, if the source and the receiver are located within the same land use categories,then the noise criteria are the indicative noise levels for that category. If the source and the receiver are notlocated in the same land use category (and are not separated by a 100 metre buffer zone), then the noise criteriaare the average of the indicative noise factors for the source and measurement locations.

Based on Clause 9, the indicative noise level (or noise criteria) is the average of the indicative noise factors forthe source zone (Special Industry) and the receiver zone. The noise criteria for the different zones are presentedbelow in Table 21.Table 21: Noise criteria for Penrice mine/quarry in zones adjacent the mine/quarry site

Development Plan Zone Noise EPP land use category Noise criteria in dB(A)Day Night

Rural (Valley Floor) Rural Industry 64 55Rural (Moculta) Rural Industry 64 55Rural Living (1) Rural Living 59 50Residential Residential 61 53

Under the Noise EPP, the measured source noise level must be adjusted by the following amounts if the noisesource contains amplitude modulating, tonal, impulsive or low-frequency characteristics:

noise source contains 1 characteristic, add 5 dB(A) noise source contains 2 characteristics, add 8 dB(A) noise source contains 3 or 4 characteristics, add 10 dB(A)
