EXECUTIVE SUMMARY

National Integrated Creative Solutions was commissioned by Stimson and Baker Planning on

behalf of Hanwha Australia Pty Ltd (the proponent) to prepare an Air Quality Impact

Assessment (AQIA) for the proposed activities, including the construction and operation stages

of an Ammonium Nitrate production plant. The proposed location is at the most eastern side of

1216 Braymont Road, Boggabri NSW (Lots 1 & 2 DP1145592).

The land is approximately 357.6 hectares (3,576,000 m2), however only a relatively small portion

of approximately 2.3 ha (23,000m2) of the land is the subject of the development and hence the

AQIA will focus on construction and operation related activities within this portion of the land.

In accordance with Narrabri Local Environmental Plan 2012, the land and obviously the proposed

site is located within the land which is zoned RU1 – Primary Production. The proposed activities

being Chemical Production are prohibited within this zone. However, a planning proposal has

already been submitted to Narrabri Council to re-zone the Eastern part of the site (approximately

36.7 ha) as Heavy Industrial. This part of the site includes the proposed development site.

In this report, we have made an assessment of all potential Air emission sources during both the

construction and operation of the plant to ensure that the surrounding environment is not

adversely impacted on by any activities associated with the proposed development. Our main

focus was on potentially sensitive receptors surrounding the site from all directions bearing in mind

that only rural residential dwelling are present in the vicinity of the site. No industrial or commercial

activities are present in the close proximity of the site. Hence, no industrial or commercial

receptors were considered in the AQIA.

Based on the previous inspections of the site as part of the assessments associated with the

preparation of the Environmental Impact Statement (EIS), we were able to identify the nearest

potentially sensitive receptors as outlined this report.

Based on our assessment, the findings, conclusions and recommendations are presented in this

document. The assessment has found that the proposed development has no potential impact on

any potentially sensitive residential receptor from air emission perspective.

The proposed operations will satisfy the acceptable air emission levels for all potential

pollutants. Approval is requested.

1. INTRODUCTION

National Integrated Creative Solutions (NICS) was engaged by Stimson & Baker Planning on

behalf of Hanwha Australia Pty Ltd (the proponent) to prepare an Air Quality Impact

Assessment (AQIA) for the proposed activities, including the construction and operation stages

of an Ammonium Nitrate production plant. The proposed location is at the most eastern side of

1216 Braymont Road, Boggabri NSW (Lots 1 & 2 DP1145592) as shown in Figure 1-1.

This report presents a brief description of the existing site and its various activities, including

the surrounding environment, the proposed activities, and an assessment of potential dust

impacts of the proposed development. The assessment has been carried out, as practically

and reasonably possible in accordance with the requirements listed in the document,

“Approved Methods for the Modelling and Assessment of Air Pollutants in NSW” published

initially by the Department of Environment and Climate Change NSW (DECC NSW 2005) and

then by the EPA in January 2017. However, the assessment outlines the air quality

assessment criteria based also on:

The Protection of the Environment Operations Act 1997

The Protection of the Environment Operations Regulation 2009

Protection of Environment Operations (Clean Air) Regulation 2002

Identifying potentially sensitive receptors

Analysing potential air emission generation from the proposed activities

The appropriate control measures to ensure compliance, if needed

It should be noted that due to the fact that the proposed activities, equipment and machinery

used have been previously assessed numerous times by highly qualified environmental

consultants at different sites across NSW, it was considered appropriate to utilise the air

quality-related information obtained from these assessments, where relevant, rather than re-do

the same assessments for the same activities, equipment and machinery. Other air emission

related information used in the assessment was obtained from the equipment manufacturers

and Hanwha’s Engineering Department.

Air emission modelling was undertaken using AERMOD, which is a NSW EPA-approved air

dispersion modelling program. Output from the modelling provides prediction of ground level

odour concentrations at the nearest potentially affected receptors from the subject site, which

are typically rural residential premises

All scenarios including worst case scenario demonstrated clear compliance with current NSW

criteria at all potentially sensitive residential receptors without the need to implement any

additional mitigation measures.

Due to the fact that the closest approved weather monitoring stations were more than 20 km

away from the proposed site, meteorological data was obtained from using the EPA’s approved

TAPM methodology by a very highly experienced company in Victoria called pDs.


13

Similarly, no local air quality data was available since no industrial or commercial activities, that

are likely to generate similar air pollutants, are in the vicinity of the site nor there is an approved

air monitoring station within 5 km of the proposed site

Figure 1-1: The Site Layout within the Relevant Portion of Land

1.1 SCOPE OF WORKS

To provide all stakeholders with greater confidence, it was determined that a list of agreed

scope of works for this assessment be outlined clearly at the outset of this document and is

shown below.

1 Review proposed activities associated with both the construction and operation stages,

2 Undertake a site investigation and surrounding properties to get a better understanding

of existing activities in the vicinity of the proposed development site,

3 Undertake research to obtain emissions data that best represents the potential air

emissions from the site,

4 Provide comprehensive and detailed calculations of all required values including air

emission rates,

5 Modelling of the proposed operations of the facility to determine the worst-case potential

air emission impacts at the nearest potentially affected sensitive receptors,

6 An assessment of the predicted levels of air emissions against NSW EPA guidelines,

7 The compilation of a report containing a summary of methods and a statement of the

potential air emission impacts from the proposed development,

8 Provide a statement of potential air emission impacts, as well as recommendations if

necessary.

1.2 THE PROPONENT

The proponent is Hanwha Australia Pty Ltd (Hanwha) which is part of the South Korean Hanwha

Group after it incorporated the Australian LDE Corporation.

2. SITE IDENTIFICATION

2.1 SITE LOCATION

The site is located at the eastern portion of 1216 Braymont Road in the suburb of Boggabri and

the Local Government area of Narrabri Shire Council (Council) in the State of New South

Wales (NSW). Full details of the site location are provided in Figures 2-1 and 2-2 as well as

Table 2-1. More Specifically, Figure 2-1 presents an aerial view of the site in the local context;

Figures 2-2 presents a closer aerial view of the site where site features can be easily identified

including the trees, farm dam and other features.

Figure 2-1: Aerial View of the Site in the Local Context

Figure 2-2: Aerial View of the Site – Closer View

2.2 SITE DESCRIPTION

The subject site is located in Boggabri, approximately 30 kilometres north of the centre of

Gunnedah (direct line) or 35 kilometres by road, and in the Narrabri Local Government Area

within the State of New South Wales. The site consists of one (1) Lot; part of Lot 1 DP

1145592. The total area of the lot is approximately 357.6 hectares (or 3,576,000 m2). The

proposed development is located at the eastern side of the existing access road where that

Section of the land is relatively flat, sloping gently towards the South and South West.

Based on Narrabri Shire Council (Council), none of the site is considered to be Environmentally

Significant Land and other than some trees, the site has one (1) farm dam. None of these

trees or the farm dam will be affected by the proposed development. On the contrary, these

existing structures will be preserved and maintained by the proponent in accordance with

current Council requirements. More details about the site characteristics and features are

included in Section 3.

The site is relatively rectangular in shape, and is surrounded by the following properties:

Northern boundary with Lots 1 and 2 DP 1131282,

Western boundary with Private Road (haul road) and then western part of Lot 1 DP

1145592,

Southern Boundary with Lot 4 DP 1015797 and Lot 5 DP 1145592, and

Eastern boundary with Lot 121 DP 834141.

A summary of site details are provided in Table 2-1.

2.3 TOPOGRAPHY

A comprehensive topographical survey was undertaken for the site. The survey included all site

features visible to the surveyor such as the dam and trees in the vicinity of the proposed

development area, the natural surface levels and contours. The survey also included measuring

the accurate dimensions of the site boundaries. A copy of the site survey was included in the EIS.

Generally speaking, the site is very flat with a gentle slope from North and North East to South and

South West.

2.4 EXISTING DEVELOPMENT

Currently, there are no developments (other than rural residential) on the site and no activities

undertaken other than normal cropping and grazing in addition to maintenance of existing

grassed areas. In addition, there is a farm dam that appears to be man-made.


18

There will be a change to the existing use of the site from rural residential to industrial, but we

believe that this will bring an improvement in the presentation/aesthetics and safety of people,

especially when the accessible areas are upgraded to a higher standard.

2.5 LAND ZONING

As previously stated, the subject site is also known as part of Lot 1 DP 1145592 which is

approximately 36.7 Hectares in area and is currently zoned as RU1 – Primary Production under

Narrabri Local Environmental Plan 2012 (NLEP 2012). The objectives of that zone, the

2.6 LOCAL TERRAIN AND STRUCTURAL EFFECTS ON DISPERSION

The meteorological condition known as katabatic flow (or katabatic drift) is often identified as

the condition under which maximum environmental impacts from primarily ground-based

sources are likely to occur. Katabatic flow is simply the movement of cold air down a slope,

generally under stable atmospheric conditions. Under such circumstances, dispersion of

airborne pollutants is generally slow and the associated impacts can reach their peak.

Katabatic flow is unlikely to affect emissions from the subject site, as the terrain is relatively flat

with a lack of significant nearby slopes.

A three-dimensional view of the site has been provided as Figure 2-6, showing the location of

the site. This figure shows the terrain with the z-axis (i.e. vertical axis) exaggerated by a factor

of 10 (i.e. a given distance on the x-axis or y-axis appears ten times as great on the z-axis) in

order to provide a clearer description of the topography. A coloured scale bar shows

elevations corresponding to the colours used in the figures. It should be noted that this figure is

an approximation of the actual terrain, based on terrain information obtained from satellite

imagery.

3. PLANT CONSTRUCTION AND OPERATION

This section presents information on the proposed activities associated with the construction and

operation of the Ammonium Nitrate production plant.

3.1 PLANT CONSTRUCTION STAGE

Based on our extensive experience with similar construction activities, we believe that the five

(5) construction phases included in Table 3-1 are very representative of what is likely to occur

on site during the construction stage. The equipment included in Column 4 is also very

representative of what is likely to be used during each of the five (5) phases of the construction

stage. Table 3-1 includes the phases, approximate timelines and equipment for the

construction stage.

Due to the flat nature of the proposed site, it is anticipated that the construction stage will

include minor earthworks that are limited to re-contouring and levelling of the site (less than

300mm). These activities are unlikely to generate any dust emissions that could be measurable

outside the boundaries of the site provided that the construction company implements the

minimal dust mitigation measures that are normally implemented on any similar activity with

minor soil disturbance activities.

3.2 PLANT OPERATION STAGE

The plant operation consists of several phases (also called nodes) and processes as outlined

below. The proposed site is shown in Figure 3-1.

Node Description

Node 1

Water unloading and StorageTanks TK-901, TK-902, TK-903, TK-904.

All water for the site will be purchased and brought in to the site by tankers and transferred to

the water holding tanks.

Water will be pumped and plumbed to the various water systems throughout the plant via 4 x

25 kL storage tanks (plant systems) and 1 x 25 kL storage tanks (cooling tower).

Water systems include:

1. Domestics supply to offices and crib rooms.

2. Various hose points (as required),

3. Boiler supply, steam system,

4. Cooling tower/heat exchanger,

5. Process/manufacturing water,

6. Eye wash stations and safety showers.

Node 2

Water Tank TK-905 to Cooling Tower and Safety Showers.

The Water Tank TK-905 has a capacity of 25 kL.

The cooling tower system will be integrated to the completed emulsion pipework.

This system will be able to draw water from the main water storage tanks into its own dedicated

and closed water system.

The water will be treated or conditioned as required to maintain a safe and uncontaminated

water source.

This water will not be used for any other purpose within the plant.

Node 3

Diesel unloading and Storage Tank TK-601 and Diesel Day Tank TK-602.

The site facility will consist of one 30 kL self-bunded storage tank, which will be connected as a

feed for the steam boiler and generator.

The diesel will be unloaded into the storage tank using the diesel tank truck pump.

Node 4


25

Mineral Oil Unloading and Storage Tanks TK-401, TK-402.

The site facility will consist of 1 x 68.8 kL and 1 x 73.86 storage tanks, which will be connected

to the Fuel Blend manufacture as a feed through the centrifugal Pump P-402.

The mineral oil will be unloaded into the storage tanks using a permanently installed pump P-

401.

Node 5

Emulsifier Storage TK-403 and TK-404 and transfer to blend tank Emulsifier will be delivered in

Intermediate Bulk Containers (IBC).

These IBCs will be unloaded and stored in a semi-bunded area with a capacity to store 50

IBC’s under a roof.

The loading point for the emulsifier and mineral oil will be contained in a bunded area for the

capturing of any spills during the blending process.

Node 6

Emulsifier / Mineral Oil Blend (Fuel Blend) Tank TK-405 Mineral oil and Emulsifier will be drawn

in the correct amounts into the fuel blend tank via pumps.

The fuel blend tank has a 5 kL capacity and is controlled by Programmable Logic Controller

(PLC) mounted on load cells.

The fuel blend tank will have a stirrer to combine the emulsifier and mineral oil correctly to the

desired mix. Once the correct batch make up has been blended, a transfer pump P-404 will

move the fuel blend to the manufacturing skid for use in the emulsion manufacturing phase.

Node 7

ANSOL Unloading and Storage TK-201 to TK-206.

There are 6 x 24 kL iso tanks plumbed to a process pump and load in pump.

All ANsol tanks will be on load cells for stock control, and process management of contents.

(QA/QC) ANsol will be sourced from Kooragang Island (Orica) manufacturing plant (hot 90%

ANsol) and be delivered to site by solution tankers. (450 kms)

All tanks will be temperature regulated by the steam boiler system to control the temperature of

the contents.

All tanks will be located on a concrete pad and contained within a concrete bund to control any

spills.

The loading point for the AN Solution will be sealed concrete area for capturing of any spills

during connection, disconnection and loading.

The storage tanks will hold the inventory of the delivery vehicle.


26

Node 8

Calcium Nitrite (CN) Solid Loading to Hopper and Augers.

A large shed adjacent to the manufacturing shed/skid will be constructed to store the CN bulka

bags. The shed will have capacity to store up to 416 bulka bags (500 t) stacked up to 3 tiers

high. Large access roller doors will provide adequate access for forklift operations to move and

manage stock rotation and usage.

Node 9

Meltdown Tanks TK-301 and TK-302 CN will be delivered to site in Bulka bags which will be

emptied into the CN hopper for inclusion into the ANSOL/CN melt tanks to create the correct

AN/CN solution.

ANSOL will be drawn by a pump into the AN/CN melt tanks. Steam will be used to maintain the

correct melt temperature, and the tanks will be mounted on load cells. The process is again

controlled by PLC panels. Once the correct AN/CN solution has been reached, transfer pumps

will move the solution into the emulsion batching tanks in the manufacturing skid along with fuel

blend and the emulsification pump to produce the final emulsion batch.

Node 10

Emulsifier Oil to Emulsifier Oil Tank TK-305

Node 11

Blend Tanks TK-303/TK-304, Pump P-301.

The process manufacturing skid is capable of drawing and mixing the correct LDE emulsion

formulation with AN/CN sol, fuel blend, steam, and emulsification pump to deliver the required

product. All process on the manufacturing skid is controlled by PLC integrated systems, with air

actuated valves, piping, and pumps.

Node 12

ANE Transfer to Storage through the heat exchanger HE-101.

Once the correct emulsion is produced in the batch/blend tanks TK-303/TK-304, the emulsion

is transferred via a pump and heat exchanger to the emulsion storage tanks ready for transport

to customer sites. The heat exchanger and associated cooling tower system will be integrated

to the completed emulsion pipework and be located between the manufacturing emulsion batch

tanks and the Emulsion storage tanks. This system will be used to reduce the ambient

temperature of the completed emulsion from the manufacturing skid from 70+ degrees Celsius

down to 55 degrees Celsius. This system will be able to draw water from the main water

storage tanks into its own dedicated and closed water system.

Node 13

Emulsion Storage Tanks TK-301/ TK-302/ TK303 2 x 55 kL (or 2 x 88 t) vertical tanks will be

used to store the completed emulsion.

The tanks will have high level alarms and trips so as to limit total storage in each tank, to

remain under the Major Hazard Facilities (MHF) limitations. The three storage tanks will be

located adjacent to the manufacturing skid and the weighbridge. A series of dedicated valves,


27

pipes and pump will be used to transfer the emulsion from the manufacturing skid to the

emulsion storage tanks, and separate series of valve, pipes and pump to load the emulsions

tankers from the storage tanks for outgoing loads to customers.

3.3 HOURS OF OPERATION

Under normal circumstances, the hours of operations are outlined below. However, these hours

may not be covered fully at the beginning as they will depend on demand with some periods

when activity is limited to the occasional loading of trucks. The proposed hours of operation

are:

Monday to Friday 6:00am - 6.00pm

4. SITE CONDITIONS AND SURROUNDING ENVIRONMENT

Land use in the surrounding area comprises of a mix of agricultural, rural and rural residential

development set within a rural landscape. Prominent rural land uses in the surrounding area

include a farm dams, several rural sheds and rural activities.

Rural residential development is the dominant land use in the surrounding area to the north,

east, south and west. The nearest residential dwelling to the development area is

approximately 1180m to the south west of the site (within Lot 4 DP 1145592). The site is

accessed from a privately owned haul road.

4.1 LOCAL TOPOGRAPHY

Based on the Aerial views obtained from Google Earth and SixMaps in addition to the

topographical survey previously mentioned, the proposed development area within the site is

reasonably flat except for the farm dam. A copy of the survey was included in the EIS.

4.2 SITE INSPECTIONS

During the preparation of the EIS and this AQIA, several site inspections were undertaken to

ensure that any assessment undertaken accurately reflected the current status of the site and

the surrounding environment. During our most recent inspection on 27 February 2017, we also

walked along both sides of the Private Road as well as Hoad Road for approximately 1km of

either sides of the subject land to ensure that several neighbouring properties located in the

vicinity of the site were briefly visited. This is extremely important in some cases where some

unapproved activities may generate offensive air emissions (or noise) including odour which

may have the potential of altering the cumulative impact on neighbouring residential receptors.

The site inspections confirmed also the previously stated surrounding environment of being

mainly of a rural residential nature with some minor agricultural activities and a few grazing

sheep here and there.

The driveway is mainly made of compacted road base and sandstone and is regularly

maintained since it is being used constantly by the owners. No major irregularities exist within

the driveway as a small sedan car as well as a relatively large truck can use the driveway

comfortably.

There is no evidence of any previous industrial or commercial activities (approved or not) within

the boundaries of the site.

The existing farm dam appears to be well maintained by the current occupier.

4.3 PHOTOGRAPHIC SECTION

Several photos were taken during the site inspections to provide the reader with a better

understanding of some of the site features. These photos are included below.
