3. Definitions
Action Limit Is a limit set by BHOP to assist in the management of noise
levels and provide an opportunity to take action to prevent the
level exceeding regulated limits.
Person in Charge/Site Manager Is the most senior BHOP person at the Rasp Mine at the time.
BATEA Best Available Technology Economically Achievable.
BMP Best Management Practice.
dB(A)
Noise is measured in units called decibels (dB). There are
several scales for describing noise, the most common being the
‘A-weighted’ scale. This attempts to closely approximate the
frequency response of the human ear.
OEH Office of Environment and Heritage, formerly The NSW
Department of Environment, Climate Change & Water (DECCW).
INP NSW Industrial Noise Policy (Published by the Environment
Protection Authority (now DECCW) in 2000).
L1 The noise level exceeded for 1 % of a measurement period.
L10
A noise level which is exceeded 10 % of the time. It is
approximately equivalent to the average of maximum noise
levels.
L90 Commonly referred to as the background noise, this is the level
exceeded 90%of the time.
Leq
It is the energy average noise from a source, and is the
equivalent continuous sound pressure level over a given period.
The Leq,15min descriptor refers to an Leq noise level measured
over a contiguous 15 minute period.
Lmax The maximum root mean squared sound pressure level received
at the microphone during a measuring interval.
RBL
The Rating Background Level (RBL) is an overall single value
background level representing each assessment period over the
whole monitoring period. The RBL is used to determine the
intrusiveness criteria for noise assessment purposes and is the
median of the ABL’s.
SI SI (“Still Isothermal”) refers to calm weather conditions (ie The
absence of any wind or temperature gradients).
Sound Power Level
This is a measure of the total power radiated by a source. The
sound power of a source is a fundamental property of the source
and is independent of the surrounding environment.
Temperature Inversion A positive temperature gradient. A meteorological condition
where atmospheric temperature increases with altitude.
() sigma-theta The standard deviation of horizontal wind fluctuation.

It is useful also to have some appreciation of the scale of decibels, the unit of noise
measurement. The following gives some practical indication as to what an average person
perceives about changes in noise levels:
Differences of less than approximately 2dB are imperceptible in general, ie, most people
would find it difficult to discern which is the louder of two noise sources having levels
within 2dB of each other; and
A difference in noise levels of around 10dB appears as either doubling or halving of
loudness.
4. Responsibilities
4.1. Mobile monitoring equipment is operational.
4.2. Maintenance and calibration of equipment occurs as required to ensure equipment reliability.
4.3. Undertake noise monitoring and reporting.
4.5. File all electronic results from noise monitoring and store information on file for a period of not less than 4 years.
4.6. Report monitoring results to the Operations Manager.
4.7. Provide adequate and timely response to community complaints and that requirements of the Complaints Procedure are completed.
4.8. Review data and determine management actions as appropriate.
4.9. Ensure actions are taken to prevent exceedence of Project Approval conditions and actions are implemented.
4.10. Make reports available to the EPA as required.
5. Standards and Policies
The noise monitoring at Rasp Mine must be undertaken in accordance with all relevant
Australian Standards and EPA policies. At the time of writing this document these include:
Australian Standard AS 1055.1-1997: Acoustics – A description and measurement of
environmental noise; and
NSW Industrial Noise Policy (INP 2000), DECCW.

6. Noise Monitoring
6.1 Compliance
To check compliance with noise limits outlined in the Project Approval the following
monitoring shall be undertaken:
6.1.1 The attended short term readings will include 15-minute samples (more than
one) at each nominated location for each of the day, evening and night
periods. The instrument will include third-octave band centre frequency
filters to aid in removing non-site related noise. The attendant will be a
suitably trained person in the practice of compliance noise monitoring. The
attendant will document and quantify the site’s contribution to noise levels at
the monitoring location. Where this is not deemed possible, an adequate data
set will be captured to allow determination of whether compliance is achieved
through the observations documented by the attendant. The instrument will
meet Australian Standard Type 1 class sound meter specifications.
6.1.2 Weather conditions including wind speed at the microphone position will be
quantified and any data collected during wind speeds above 5m/s at the
microphone will be deemed unsuitable. Similarly, 10m elevation wind speed,
wind direction and temperature gradient data will be reported for the
duration of monitoring using the site’s automatic weather station (AWS). The
weather data will be used to assess compliance in accordance with consent
conditions.
6.1.3 In addition to the noise parameters listed in Table 2, the monitoring will also
capture background noise levels including L90,15minute and over time
establish trends in the rating background level (RBL) and whether this is
influenced by site noise or not.
Placement of instruments will consider extraneous sources such as roads and be
positioned on the site side of these sources where practicable. The instrument will
include low-pass frequency filters to exclude insect and other natural sounds above
1000Hz. The instrument will meet Australian Standard Type 1 class sound meter
specifications.
A continuous monitor was previously located at Piper Street North however this sampler
has been removed due to continued vandalism. In a situation where the site is found to
be non-compliant at a particular location the location will be assessed using attended
noise monitoring conducted by trained BHOP staff. Currently attended noise monitoring

6.3 Action Limits
During any attended noise monitoring, the following will apply:
Where the site’s contribution is 2dB below the operational license limits for a given
receiver, the main contributing source(s) will be noted;
Where the site’s contribution is at the operational license limit for a given receiver,
the main contributing source(s) will be identified and investigations undertaken to
determine reasonable and feasible mitigation.
Where the site’s contribution is above but within 2dB of the operational license
limits for a given receiver, the main contributing source(s) will be identified and
investigations undertaken to determine reasonable and feasible mitigation. Where
this cannot be resolved, replacement of the offending item will be considered.
Where the site’s contribution is more than 5dB above the operational license limits
for a given receiver, the main contributing source(s) will be identified and its
operations will cease until such time as suitable mitigation can be adopted to ensure
noise levels are reduced.

(iii) Enclosure by enveloping the noise source or those exposed.
7.3 Criteria exceedances will be determined with consideration of the operational noise
criteria as published in the Project Approval and the INP which states the following:
A development will be deemed to be in non-compliance with a noise consent or
licence condition if the monitored noise level is more than 2 dB above the
statutory noise limit specified in the consent or licence condition. This may occur
for two reasons:
• The noise from the development is excessive, in which case the development is
truly not complying with its consent or licence condition.
• The noise was increased by extreme, nonstandard weather effects—in which
case the development is not considered to be in noncompliance with its
consent or licence condition. Nonstandard weather effects can be considered
to be present during monitoring if the cloud cover is less than 40 per cent and
the wind speed (at 10 m height) is less than 1.0 m/s (represents an extremely
adverse weather condition for noise)—during the period from 6 pm to 7 am in
non-arid areas (see Section 9.2).
In this latter case, further monitoring at a later date is required to determine

The Environment and Community Officer shall notify the Department of Planning and
Infrastructure and any other relevant agencies, of any incident associated with the
Project in accordance with Schedule 4, item 5 of the Project Approval.
8. Noise Level Management
8.1 New Purchases
Noise levels shall be considered as part of the selection criteria for new plant and
equipment to ensure the best available technology economically achievable (BATEA) is
applied to reduce and or minimise noise levels at the operation
8.2 Best Management Practices
The following best management practices are used to minimise noise levels:
Independent noise audits will be undertaken as required by the EPA.
Noise awareness information is provided in employee and contractor inductions.
The crusher has been located behind the ore stockpile and in a gully to minimise
noise levels.
Construction of noise barriers with 4m high bunding along the southern side of the
haul road and the southern perimeter of the ROM pad mine truck haul route.
Re-locating the processing plant to the north-eastern end of the site, away from
residential dwellings to the south.
Cladding of the primary crusher and installing noise abatement bunding to the north
and south of the crusher.
Enclosed conveyors and transfer stations prior to the grinding circuit.
Installation of two overlapping bunds at the northern side of the wagon stockpile
area to shield Crystal Street residences.
Silencers installed on haul trucks and noise suppression kits on the loaders used on
the ROM pad, container stockpile and rail loading areas;
Properly maintained plant to ensure rated noise emission levels are not exceeded.
Mining ore transport trucks, once loaded, shall follow the designated heavy vehicle
route through Broken Hill.
Operational restrictions to minimise noise, including:
Crushing activities to occur 24 hours (on any day);
Shunting of concentrate wagons to occur only between 7am and 6pm (on any
day); and
Production rock blasting to occur only between 6:45am and 7:15pm (on any day).

8.3 Best Available Technology Economically Achievable (BATEA)
Where an Action Limit is exceeded and it is attributed to truck haulage operations
(trucks in and out of Kintore Pit or processing plant), investigations shall be undertaken
to identify ways to reduce noise levels by way of best management practices as detailed
in Section 8.2.
Where best management practices are unable to minimise noise emissions sufficiently,
the BATEA methods such as those listed below should be considered:
Adjustment of reverse alarms to reduce acoustic range and or tone.
Use of acoustically efficient muffler design.
Substitution of louder engines.
Enclosing noise sources.
Increasing surface roughness.
Use of alternative methods to pneumatic/hydraulic rock hammers.
Maintaining levels in ore bins to minimise impact when filling.

Appendix A
Email correspondence with relation to submitted Management Plans to Department of
Environment and Planning under Mod 3 from the EPA is as follows:
Good morning Len, as per our recent discussions all of the management plans submitted (Apart from “Air Quality”) have previously be lodged with the EPA as part of Pollution Studies and Reduction Programs attached to the Environment Protection Licence. Hence, the EPA has no further comment in relation to these. The Air Quality Management Plan & Air Quality Monitoring Program Management Plan have been reviewed. The EPA advise that given the data information now available BHOP should propose licence limits to the EPA for the Mill Baghouse – Total Solid Particles and Type 1 and Type 2 substances emissions as per project approval requirements. The EPA support the methods being implemented in the Air Quality Management Plan however advise that the timeframe's for the implementation of these controls needs to be formalised specifically the irrigation system for the tailings facility and the video recording system for dust emissions. The EPA also advise that air pollution methods could be improved via the introduction of policies and procedures to ensure that controls are implemented more routinely and automated systems installed removing human interpretation and or error. For example: •Tailings Storage Facility 2 (TFS2) Operation: An irrigation system is proposed as dust management - This should be installed to ensure controls are in place before any issues arise and could be an automatic system that is weather activated Eg. If wind speed exceeds a certain nominated kilometre per hour sprinklers activate and or deactivate. Any manual watering systems need activation procedures (trigger points) to avoid methods based on individual interpretations; •Unloading Ore to ROM stockpile: Manual water sprays could converted to weather activated and automatic and routine to avoid human error (Weather activated); •Exposed Areas: Chemical dust suppression use could be applied over set time periods and subject to set time frame inspections to determine if additional application is required prior to the rostered application; •Sealed Roads: Street sweeper could be routinely rostered for use at set time periods with additional inspections to determine if more frequent use is required;

•ROM Stockpile Wind Erosion: Stockpiles should be kept below surrounding bunds removing the “as much as practicable” component; •Frontend loader Operation/Apron Feeder Hopper at ROM Pad: Inspection of the irrigation system could be more frequent with set time frames and the cessation of works procedure could be formalised through guidelines Eg. If wind speed exceeds a certain nominated kilometre per hour a stop work is activated; and •Concentrate Handling: Works are undertaken within an enclosed building however truck drivers are responsible for manually opening and closing the entry/exit doors - the doors could be automatic.
The EPA concur with the NSW Department of Planning and Environment’s comments in relation to their review of the management plans submitted.

Hello Tansley,
I’ve just been in contact with Stephen Shoesmith from Planning (details attached) and he has
given me feedback on the attached management plans for the project approval. The 2 Air
quality plans and the 3 blasting/noise plans relate to conditions 11 and 20 respectively in the
project approval. As such planning require these plans to be prepared I consultation with the
EPA which is a whole step I missed for these particular plans. Planning have already reviewed
the documents, their feedback I s attached. Would you be able to review these documents
and provide feedback to ensure they meet the requirements of the EPA in relation to our
licence?

The feedback does not have to be exhaustive just establish whether or not the you consider
the documents to be adequate and if needed what changes are necessary.
Air Quality Management Plan 11. The Proponent shall prepare and implement a detailed Air Quality Management Plan for the project to the satisfaction of the Secretary. This plan must: (a) be prepared in consultation with EPA and submitted to the Secretary for approval prior to the commencement of construction on the site; (b) identify all major sources of particulates and other air pollutants that may be emitted from the project, being both point source and diffuse emissions, including identification of the potential for lead contamination to be carried by these particulates; (c) include an air quality monitoring program that: • provides for periodic point source monitoring at Point 1 (Ventilation Shaft) and Point 2 (Process Enclosure/ Baghouse Stack); • provides for continuous ambient monitoring across an ambient air quality and dust monitoring network comprising no fewer than ten monitoring locations (Points 3 to 12) for total suspended particulates, PM10, lead and dust deposition. Monitoring locations shall be informed by the outcomes of the air quality assessments presented in the EA and PPR and identified in consultation with EPA; and • provides for continuous meteorological monitoring using a meteorological monitoring station located on the site; • is consistent with the requirements of Approved Methods for the Sampling and Analysis of Air Pollutants in New South Wales (DECC, 2007), the Protection of the Environment Operations Act 1997 and the Protection of the Environment (Clean Air) Regulation 2010. (d) pro-active and reactive management and response mechanisms for particulates with specific reference to measures to be implemented and actions to be taken to minimise and prevent potential elevated air quality impacts (including ambient air and deposited dust impacts) on surrounding land uses as a consequence of meteorological conditions, upsets within the project, or the mode of operation of the project at any time; (e) procedures and processes for monitoring ambient dust and deposited dust impacts; (f) provision for regular review of dust monitoring data, with comparison of monitoring data with that assumed and predicted in the documents referred to under Condition 2 of Schedule 2; (g) details of measures to be implemented to address any situation in which monitored dust impacts exceed those assumed and predicted in the documents referred to under Condition 2 of Schedule 2; (h) specific complaints management procedures in the event that dust monitoring indicates elevated off-site impacts; (i) procedures for the minimisation of dust generation on the site; (j) protocols for regular maintenance of plant and equipment to minimise the potential for elevated dust generation, leaks and fugitive emissions; and (k) a contingency plan should an incident, upset or other initiating factor lead to elevated dust impacts, whether above normal operating conditions or above environmental performance goals/ limits.
Noise and Blast Management Plan 20. The Proponent shall prepare and implement a Noise Management Plan for the project to the satisfaction of the Secretary. This plan must: (b) be prepared in consultation with EPA, and submitted to the Secretary for approval by the end of June 2011; (c) describe the noise mitigation measures that would be implemented to ensure compliance with the relevant conditions of this approval, including a real-time noise management system that employs both reactive and proactive mitigation measures; (d) include a noise monitoring program that: • uses a combination of real-time and supplementary attended monitoring to evaluate the performance of the project; and • includes a protocol for determining exceedances of the relevant conditions of this approval; (e) describe the blast management measures that would be implemented to ensure compliance with the blast criteria and operating conditions of this approval; and (f) include a blast monitoring program that: • evaluates the performance of the project, including compliance with the applicable criteria; • uses a combination of roving blast monitors (at least 1) and fixed blast monitors (at least 6); and • includes a protocol for determining and responding to exceedances of the relevant conditions of this approval.
