1998) Environmental Impact Assessment regulations.
1.4
The National Environmental Management Act (NEMA) EIA
regulations list activities that may have a significant impact on the
environment, and which consequently require authorisation from the
Department of Economic Development, Environmental Affairs and
Tourism (DEDEAT). The regulations further specify the assessment
process and the information that is required to enable DEDEAT to
make a decision regarding the activity. It is understood that a BA
process is required in terms of the NEMA EIA regulations as the
project may involve (as a minimum) the following activity:
The BAR provides information about the proposed activity, a
description of the affected environment (including ecological, land
use and socio-economic aspects), a description of the process
undertaken in order to consult the public on the activity, as well as a
basic assessment of the potential impacts of the activity on the
receiving environment.

Site Location and Surroundings
The proposed Air Separation Plant is to be located in Zone 3 (light
industrial cluster) of the Coega IDZ between Hamile Road to the
south and Bumba Road to the north.
1.6
The Proposed Development
The project involves the construction and operation of a new ASP to
supply various customers in Port Elizabeth as well as the Eastern
Cape region with Oxygen, Nitrogen and Argon. The ASP includes
an ASU for the production of Oxygen, Nitrogen and Argon, storage
tanks for the on-site storage of the liquefied gases LOX, LIN and
LAR and associated infrastructure.
The new ASP has a total design production capacity of 150 tons per
day (tpd) which is made up of 100 tpd LIN, 50 tpd LOX and 3 tpd
Argon.

Figure S-1: Typical Basic Assessment Process
Process Description
The plant is to use the process of cryogenic air separation for the
production of the gaseous products. The Pure gases can be
separated from air by first cooling it until it liquefies, then selectively
distilling the components at their various boiling temperatures. The
operation process follows a number of steps, the first of which is the
air is drawn into the process and compressed and cooled. The
condensed water is removed before the process air passes through
the molecular sieve station which removes any remaining water
vapour, carbon dioxide and any hydrocarbons. After passing through
the Molecular Sieve the process air is further passed through a
series of compressors and coolers and then enters the coldbox. In
the coldbox the process air undergoes the process of rectification.
This process results in the production of Lox and Lin which are then
fed to the storage tanks. During this rectification process a vapour
side draw is taken from where the argon concentration is highest
and sent to the argon column system for further processing, from
here where pure argon is withdrawn and fed to the storage tank.
The process entails the assessment of the activity and the
compilation of a BAR (see Section 2) for public comment. Issues
and concerns raised by the public after the distribution of the Draft
BAR have informed the Final BAR which, together with the
prescribed Comment and Reponses Report, have been submitted to
DEADEAT for a decision. A typical Basic Assessment process is

transport. Since LOX and LIN have a very low temperature (approx.
-200 C), special storage tanks are required. The storage tanks are
constructed with a double shell; whereby the inner vessel is made of

regarding the proposed activity.
 High: the potential impact will affect a decision regarding the
proposed activity.
 Very High: the proposed activity should only be approved
under special circumstances.
To ensure the distribution of the liquid products (LOX, LIN or LAR),
three filling pumps are included in with the ASP. The filling pumps

Public Consultation Process
A public participation process aimed at allowing the public to
participate and to be involved in the environmental process has
been carried out. The public participation process completed to date
includes the following:
 Newspaper advert (Die Burger);
 Screening of an E-Notice on the CDC’s electronic notice board
in the foyer of the Coega Business Centre;
 Distribution of an Executive Summary of the Draft BAR to IAPs
for comment; as well as the placement of copies of the Draft
BAR in public libraries for public review for a period of 40 days.
Comments received on the Draft BAR have been included in the
Final BAR.
1.9
Assessment of Potential
Environmental Impacts
A number of potential impacts of the proposed development were
identified by the project team and specialists. The project
alternatives, and most of the identified impacts, were considered by
the Environmental Assessment Practitioner.
Potential impacts were assessed using SRK’s impact assessment
methodology. The significance of an impact is defined and
assessed as a combination of the consequence of the impact
occurring (based on its extent, intensity and duration) and the
probability that the impact will occur.
For all potentially significant impacts, the significance of the
anticipated impact was rated with and without recommended
mitigation measures. These are presented in Table 1 (refer to
section D of the BAR form for a complete list of impacts assessed)
which summarises:
 The impacts that were assessed;
 Their significance following the implementation of mitigation
measures; and
 The key mitigation measures on which the significance rating
is based.
The impact significance rating should be considered by the
competent authority in their decision-making process based on the
definitions of ratings ascribed below.
 Insignificant: the potential impact is negligible and will not
have an influence on the decision regarding the proposed
activity.
 Very Low: the potential impact is very small and should not
have any meaningful influence on the decision regarding the
proposed activity.
 Low: the potential impact may not have any meaningful
influence on the decision regarding the proposed activity.
GARR/ELSR
 A very low noise impact was predicted during construction
activities as this would be temporary. With mitigation, these
impacts could be reduced to insignificant;
 Socio economic impacts were determined to be insignificant, in
the construction phase of the development, due to the
relatively small scale nature and short time period of the
construction activities. With the use of local labour and other
measures this can be increased to a very low (+ve)
significance;
 The potential impacts from the loss of indigenous flora and
fauna on the site during the construction phase are considered
to be very low (-ve) with mitigation;
 The potential heritage impacts (archaeological &
palaeontological) during the construction phase are considered
to be of a very low (-ve) significance; however with mitigation
the significance of these potential impacts could be optimised
to a very low (+ve) significance;
 The potential air quality impacts (dust) on the site during the
construction phase are considered to be very low (-ve), as
construction will be over a short period. With mitigation, the
significance of these potential impacts could be reduced to
insignificant;
 Waste management impacts were anticipated to be very
low (-ve) due to the limited construction activities. With correct
disposal of waste this impact can be reduced to insignificant;
 Traffic impacts during the construction phase are considered
to be insignificant;
 Safety impacts during the operational phase are predicted to
be very low due to the safety measures that are to be
incorporated;
 Noise during the operational phase is rated as a low (-ve)
significance as the plant is to be located in an industrial area
and is it is anticipated that the noise emissions will remain
within the permissible limits;
 The proposed operational phase of the plant is anticipated to
result in approximately 20 jobs, which was rated to be of a
low (+ve) socio economic significance;
 The significance of the contamination of surface and ground
water was rated as very low (-ve) which could be reduced to
insignificant with the implantation of mitigation measures;
 Traffic impacts during the construction phase are considered
to be very low (-ve) due to the measures that have been
incorporated into the plant layout, as well as it is anticipated
that a maximum of 7 trucks will access the plant in a 24 hour
period;
 The cumulative effect of surrounding developments on safety
is rated as very low (-ve) as a result of the safety measures
that are to be incorporated into the plant;
 The cumulative effect on noise impacts is rated as low as the
anticipated noise levels of the plant are shown to be below the

Introduction and Background:
African Oxygen (Pty) Ltd (Afrox), part of the Linde Group, proposes to construct and operate a
new Air Separation Plant (ASP) that includes an Air Separation Unit (ASU) and associated
infrastructure for the storage and handling of liquefied gases. It is proposed that the ASP be
located in Zone 3 (Light Industrial Cluster) of the Coega Industrial Development Zone (IDZ), a
locality map has been attached in Appendix A of this final Basic Assessment Report (BAR).
At the ASP ambient air is to be used in the ASU, without any intermediates or chemical
conversions, to produce Oxygen, Nitrogen and Argon. The products will be stored in storage
tanks as liquefied gases; liquid cryogenic Oxygen (LOX), liquid cryogenic Nitrogen (LIN) and
liquid cryogenic Argon (LAR).
Of the gases that are going to be handled and stored on site (Oxygen, Nitrogen and Argon)
only Oxygen is classified as a dangerous good according to SANS No. 10234, supplement
2008, Edition 1.00. Nitrogen and Argon are not listed in SANS No. 10234, supplement 2008,
Edition 1.00. Based on the design capacity of the ASU and the capacity of the storage tanks,
the total storage capacity of dangerous goods (Oxygen) in the new ASP, as shown in table 3
below, is within the thresholds listed in Activity No. 13 of Listing Notice 1 (GNR 544,

Process Description
Pure gases can be separated from air by first cooling it until it liquefies, then selectively
distilling the components at their various boiling temperatures. The air is used as an industrial
source of nitrogen, oxygen, argon for technical and medical uses.
The separation process requires a very tight integration of heat exchangers and separation
columns in order to be efficient. A prerequisite of an ASU is a refrigeration cycle which is
required to achieve the low distillation temperatures required. The cooling will be achieved
through compression and expansion as well as through heat exchange against liquid products.
A simplified flow diagram of the process (Appendix C2) shows the main components as well as
the supply- and product streams of the ASU and storage systems. The reference numbers
provided in brackets in the section below refer to the more technical process flow diagram
which is attached as Appendix C3.
The operation process is as follows:
1. Air compression and precooling system
Ambient air is drawn into the process at the ‘air intake’ point, the incoming air is first
cleaned from dust and other particles in an air filter (S1146) and then compressed to a
pressure of approximately 6 bar by a multistage turbo-type air compressor (C1161). This
compressed air enters the ‘cooling water after cooler’ (E1121) and subsequently the
‘chilled water after cooler’ (E2418) where it is finally cooled down to around 15°C. It then
passes through a water separator (D2431) which removes the condensed water before
entering the molecular sieve station.
2. Molecular sieve station (air purification)
The process air passes through the molecular sieve station; which removes any remaining
water vapour, carbon dioxide (CO2) and any hydrocarbons.
The adsorbents have a limited adsorption capacity and need to be regenerated after a
certain time. While the air passes through one adsorber vessel, the other adsorber vessel
goes through a regenerating cycle. This regeneration process involves a heating cycle
whereby a hot dry stream of nitrogen gas is heated by an electric heater (E2618), and
passed through the molecular sieve in the opposite direction to the normal process air flow.
This is followed by a cooling cycle during which the adsorber is cooled with dry nitrogen
gas which bypasses the electric heater.
The adsorbers are continuously alternating between the adsorption cycle and the
regeneration cycle, in this way one adsorber is always available for the air purification
process.
3. Process streams distribution and refrigeration, air recycle
After passing through the Molecular Sieve the process air is further passed through a
series of compressors and coolers. The compressed chilled air enters the coldbox (see
box 1 below) where it is further cooled to around condensing temperature.
Box 1: Description of the coldbox
The coldbox houses the equipment for the cryogenic air separation process. It is
positioned between the Machine House and Storage Tanks in a vertical position; its
anticipated dimensions are 34.59 x 4.2 x 4 m. The coldbox is completely assembled off
site.
4. Rectification (Oxygen & Nitrogen) pressure column
In the pressure column (T3211) the air is separated into pure nitrogen, yielding at the top of
the column and into oxygen enriched liquid at the bottom of the column; through a process
of repeated distillation known as rectification.
Liquid oxygen product (LOX) is withdrawn from the sump of the low pressure column, subcooled and fed to the LOX storage tank; with the liquid nitrogen product (LIN) being
withdrawn from the top of the low pressure column to the LIN storage system.
5. Argon Extraction
When argon is produced, a vapour side draw is taken from the low pressure column where
the argon concentration is highest and is sent to the crude argon column system which is
separated into two column sections (T4110/ T4111) in order to keep the cold box height in
reasonable limitations. The pure liquid argon product (LAR) is withdrawn from the bottom of
the pure argon column and fed to the LAR storage tank.
6. Product storage
Liquid oxygen (LOX), liquid nitrogen (LIN) and liquid argon (LAR) are each stored in
large-capacity tanks at a slight overpressure ready for liquid transport. Since LOX and LIN
have a very low temperature (approx. -200 C), special storage tanks are required. The
storage tanks are constructed with a double shell; whereby the inner vessel is made of
stainless steel, and acts as the liquid storage vessel, and the outer vessel is made of
carbon steel. The storage tanks are vacuum insulated and equipped with appropriate
safety valves.
The three 300 m³ and one 10 m³ LIN tanks, as well as the one 50 m³ LAR tank, are
positioned vertically while the one 300 m³ LOX tank is positioned horizontally (see
diagrams included in Appendix C). This allows for the different products to be gravity fed to
the storage tanks from the pressure columns situated in the coldbox, thereby eliminating
the need for pumps.
7. Filling System
To ensure the distribution of the liquid products (LOX, LIN or LAR), three filling pumps are
included in with the ASP. The filling pumps are positioned near the storage tanks and each
pump is fed from a separate storage unit to ensure that there is no mixing of the products.
The liquefied products are transferred into trucks for distribution; it is anticipated that
approximately 6 trucks will be required per day in order to meet the demand.
In order to ensure that the trucks do not exceed the total weight allowed to drive on public
roads, every truck will be weighed upon arrival and departure via a central truck weigh
bridge. The filling process is then controlled via a flow meter in order monitor, measure
and record the loading of the trucks. Each distribution order will be controlled by a Linde
process-system called “SALSA”. The SALSA system ensures, among other things,
checking of the suitability and permission of vehicles for the desired product, determination
of the allowed cargo load, material identification and protection against overfilling.
Associated Infrastructure
Truck Service Point
The truck service point consists of a wash bay, a truck service area and a small tyre and
spares store of approximately 10 m² in size. In this way trucks can be washed and receive
attention for small maintenance issues (e.g. replace tyres).
Fuel Filling Station (Diesel)
The fuel station allows trucks to be filled up with Diesel if necessary. The filling station includes
a 25 000 litre double walled underground storage tank, equipped with a leak detection system,
and a filling pump.
Operating Hours and Staff
The ASU is designed for continuous on-site operation from a local control room or via remote
operation control from a remote central control room. AFROX are responsible for the proper
operation of the ASP and for performing regular inspection, maintenance, servicing and repair
work on site.
The plant is designed for continuous operation, 24 hours a day 365 days a year. In order to
operate effectively the ASP will require 8 persons for transport-works and an additional
12 persons for plant operation. The plant operators are to work in three shifts resulting in
4 operators per shift. The plant is to be staffed around the clock by at least one trained and
skilled employee.
Utilities
Electrical Power
The new ASP will be connected to a 11 kV, 50 Hz substation (see appendix C14) by Nelson
Mandela Bay Municipality (NMBM). The substation is to be located on the western boundary of
the site as indicated in the layout plan (Appendix C1). The 11kV cable system between the
NMBM substation and the ASU plant will be directly buried. The ASU plant requires 4250 kW
for operation.
Water
The new ASU plant is anticipated to utilise 14 m³/h of potable water for make-up water.

Site Access and Plant Safety
The ASU is to be situated in Zone 3 of the Coega IDZ between Hamile Road to the south and
Bumba Road to the north. Access to Zone 3 can be gained from two points, namely; from the
Coega IDZ via Neptune Road and from the R102. The whole plant site will be fenced and
access to the plant will only be permissible via authorisation and will be from the south side of
the plant, via a controlled entrance off Hamile Road.
The plant is provided with safety-related monitoring and protection equipment as well as being
fitted with automatic shut-offs and emergency stop switches. In addition, a risk analysis
(“HAZOP-Study”) will be performed for the entire system, in which the proposed measures
against hazards are evaluated. As a result dangerous conditions such as excessive pressures,
extreme temperatures and the accumulation of critical materials or leakages will be prevented.
Timeline
It is envisaged that the plant is to be operational by March 2015.
2.
FEASIBLE AND REASONABLE ALTERNATIVES
“alternatives”, in relation to a proposed activity, means different means of meeting the general
purpose and requirements of the activity, which may include alternatives to—
(a)
the property on which or location where it is proposed to undertake the activity;
(b)
the type of activity to be undertaken;
(c)
the design or layout of the activity;
(d)
the technology to be used in the activity;
(e)
the operational aspects of the activity; and
(f)
the option of not implementing the activity.
Describe alternatives that are considered in this application. Alternatives should include a consideration
of all possible means by which the purpose and need of the proposed activity could be accomplished in
the specific instance taking account of the interest of the applicant in the activity. The no-go alternative
must in all cases be included in the assessment phase as the baseline against which the impacts of the
other alternatives are assessed. The determination of whether site or activity (including different
processes etc.) or both is appropriate needs to be informed by the specific circumstances of the activity
and its environment. After receipt of this report the competent authority may also request the applicant
to assess additional alternatives that could possibly accomplish the purpose and need of the proposed
activity if it is clear that realistic alternatives have not been considered to a reasonable extent.
ALTERNATIVES CONSIDERED
1. Location
Port Elizabeth was chosen as the location to establish the new Air Separation Plant due to its
proximity to Afrox’s main clients in the region. The Coega IDZ was specifically chosen due to the
benefits of being associated with an IDZ, the infrastructure and the future development growth of
the area. The specific site within Zone 3 of the IDZ was identified by the CDC.
As such no alternative site is proposed.
2. Type of activity
Afrox specialises in the gas industry and currently supplies gas products (specifically Oxygen,
Nitrogen and Argon) to the Eastern Cape region. As the demand for these products grow Afrox
have had to assess the most effective way to continue supplying the area in the future. Afrox have
an existing filling station in Port Elizabeth which relies on the importing of the gas products from
other regions of the country which is expensive and not viable in the long term, due to this reason
expanding the filling station was deemed non-viable. A smaller type of ASU, which involves a
pressure separation process, was considered but this was removed as an option due to the low
purity that of the resulting products. Therefore the only viable option is to install a cryogenic ASU
plant capable of meeting the current as well as future anticipated demands.
As such no alternative activity is proposed.
3. Design and layout
The design and layout of the plant has been altered to incorporate the CDC Architectural
Guidelines, this included the relocation of the car park to the front of the building to meet the
requirement of not building within the identified reserve; the accommodation of trucks on the Afrox
property (i.e. off the road) to avoid traffic congestion and the design of the building to fit in with
required guidelines. The buildings have also incorporated environmentally sustainable design
measures to improve the efficiency of the heating and cooling systems of the buildings by insulating
them as well as glazing the windows.
As such no alternative design/layout is proposed
4. Technology alternatives
The Linde Group, of which Afrox is a member, is a world leading supplier of industrial, process and
specialty gases. They have been in industry for 130 years during which time they have made major
technological advances which have resulted in the increased efficiency of the process. This best
available technology is to be utilized in the proposed Air Separation Plant.
As such no alternative technology is proposed
5. Operational aspects
As part of the operations of the plant a fully closed cooling system was considered, however; this
option was eliminated as a result of the increased power and reduced efficiency that it would cause.
As such no alternative operational aspects are proposed
6. No go alternative
The No Go alternative would result in Afrox having to continue importing products from other
regions of the country. This method is expensive and results in a large amount of trucks having to
travel long distances on the roads transporting the products. This approach is considered to not be
economically viable to continue to meet the current and future demand requirements of the
industry.
Paragraphs 3 – 13 below should be completed for each alternative.

Need and desirability of the activity
Motivate and explain the need and desirability of the activity (including demand for the activity):
Currently Afrox purchases LIN & LOX from PetroSA in Mosselbay to supply the Eastern Cape market
(approximately 400 km away from the market). This source is no longer sufficient to meet the demand
and the shortfall is imported from Afrox’s Cape Town facility, more than 800 km away. Argon is
imported from Afrox facilities in the inland power zone (either Witbank or Pretoria) more than 1 100 km
away from the market.
Afrox proposes to invest in a 150 tpd (100 tpd LIN, 50 tpd LOX, 3 tpd LAR) stand-alone merchant plant
in Port Elizabeth. Establishment of the ASU in Port Elizabeth will provide Afrox with a cost effective
and reliable solution, compared to the traditional expensive and unreliable model of transporting the
products across large distances. Building a plant of this size will allow Afrox the opportunity to protect
its current market position, but to also capitalize on future growth opportunities that are anticipated for
this region.
It is proposed that the ASU be located within the Coega IDZ. More than 90% of the LIN and 60% of
the LOX demand is centred in Port Elizabeth.
Indicate any benefits that the activity will have for society in general:
The establishment of an ASU in the region will have the following associated benefits:
 Afrox’s merchant market in the Eastern Cape comprises of 25 LOX customers (19 of which are
hospitals), the ASU will improve reliability of LOX supply for these hospitals by reducing the
dependency on supply from sources outside of the province;
 The reduction of transportation distances resulting from bringing in LIN, LOX & LAR from outside of
the province;
 Competitive pricing structure for industries reliant on LIN, LOX & LAR in the region; and
 Jobs will be created during the construction phase of the ASU.
Indicate any benefits that the activity will have for the local communities where the activity will be
located:
The local communities will benefit from the employment opportunities that will be created during the
construction phase of the air separation plant.

WASTE, EFFLUENT, EMISSION AND NOISE MANAGEMENT
11(a) Solid waste management
Will the activity produce solid construction waste during the
YES
construction/initiation phase?
If yes, what estimated quantity will be produced per month?
Minimal
How will the construction solid waste be disposed of (describe)?
Small quantities of solid waste produced during the construction phase of the proposed
development and will primarily consist of building rubble and litter (e.g. plastic, glass, etc.). The
contractor will remove and discard any waste resulting from construction to the closest
registered waste disposal site. Where possible, construction waste will be re-used and/or
recycled.
Any hazardous waste will be collected and stored separately according to the specific
requirements of the waste type and will be collected by an approved waste disposal service
provider and will be disposed of at an approved hazardous waste disposal landfill site.
Where will the construction solid waste be disposed of (describe)?
As above
Will the activity produce solid waste during its operational phase?
YES
Minimal
How will the solid waste be disposed of (describe)?
Very small quantities of waste will be generated during the operational phase and are readily
accommodated within the existing waste management infrastructure within the Nelson Mandela
Bay Municipal area.
An integrated waste management approach that is based on waste minimisation will be used
and should incorporate reduction, recycling, re-use and disposal where appropriate. All general
waste material (e.g. non-hazardous waste) will be contained in general waste bins and
disposed of via the municipal waste system.
Hazardous substances (e.g. oil rags, oil cans, spent molecular sieve, etc.) will be disposed of at
an appropriate classified waste site (unless it is to be recycled by approved methods), as per
the National Environmental Management Waste Act, 2008 (Act 59 of 2008).
Where will the solid waste be disposed if it does not feed into a municipal waste stream
(describe)?
As above
If the solid waste (construction or operational phases) will not be disposed of in a registered
landfill site or be taken up in a municipal waste stream, then the applicant should consult with
the competent authority to determine whether it is necessary to change to an application for
scoping and EIA.
Can any part of the solid waste be classified as hazardous in terms of the
NO
relevant legislation?
If yes, inform the competent authority and request a change to an application for scoping and
EIA.
Is the activity that is being applied for a solid waste handling or treatment
NO
facility?
If yes, then the applicant should consult with the competent authority to determine whether it is
necessary to change to an application for scoping and EIA.
11(b)
Liquid effluent
Will the activity produce effluent, other than normal sewage, that will be
NO
disposed of in a municipal sewage system?
Will the activity produce any effluent that will be treated and/or disposed of on Yes
NO
site?
If yes, the applicant should consult with the competent authority to determine whether it is
necessary to change to an application for scoping and EIA.
Will the activity produce effluent that will be treated and/or disposed of at
NO

Describe the measures that will be taken to ensure the optimal reuse or recycling of waste
water, if any:
The ASU will generate condensate, on a continuous basis, from the following sources:
 Condensate from compressor: 7.2 m³/h (172.8 m³/day)
 Side-stream blow down: 23.76 m³/h for 20 minutes every two hours (95.04 m³/day)
 Cooling water blow down: 7 m³/h (168 m³/day)
This water will be discharged to the municipal sewer and is expected to meet the municipal
effluent discharge standards (being essentially condensation from the atmosphere containing
no additives from the process). No treatment or re-use of this water will take place.
A control pit will be installed to ensure that only rainwater is sent to the collection system. The
course of the pipelines for surface water and for sewerage is shown in Appendix C15.
11(c)
Emissions into the atmosphere
Will the activity release emissions into the atmosphere?
If yes, is it controlled by any legislation of any sphere of government?
If yes, the applicant should consult with the competent authority to determine
whether it is necessary to change to an application for scoping and EIA.
If no, describe the emissions in terms of type and concentration:
NO
NO
It is probable that dust will be generated during the construction phase, particularly during high
wind conditions. Mitigation measures are provided in the EMPr and will become legal and
binding once authorisation is received from the authorities.
During operation of the plant the ambient air is sucked in and separated as product streams in
the elements Oxygen, Nitrogen and Argon. The remaining air is discharged back to the
atmosphere. Only small amounts of evaporation losses from the storage tanks for liquefied
gases (Oxygen, Nitrogen and Argon) and some further amounts of impure Oxygen, Nitrogen
and Argon at the ASU are emitted. All emitted gases are components of the ambient air
originally drawn in, and contain no additional components.
11(d)
Generation of noise
Will the activity generate noise?
YES
If yes, is it controlled by any legislation of any sphere of government?
NO
If yes, the applicant should consult with the competent authority to determine
whether it is necessary to change to an application for scoping and EIA.
If no, describe the noise in terms of type and level:
Noise will temporarily be generated during the construction phase due to plant machinery,
equipment and vehicle movement; however, due to the location of the plant as well as the short
term of the construction period it is not anticipated to result in a significant impact.
During the feasibility study of the new air separation plant a noise impact assessment was
undertaken by the engineering office of IBAS (Ingenieurgesellschaft für Bauphysik, Akustik und
Schwingungstechnik mbH). A copy of the assessment has been attached to this BAR as
Appendix G. The operation is anticipated to operate 24 hours a day 365 days a week and as
such the basis for the calculation refers to normal operating conditions of a stationary operation
(24 hours a day), with a constant noise level by the process plant. Additional truck driving and
loading takes place 24 hours a day.
The assessment has taken into consideration that during operation the relevant sound sources
(compressors, pumps etc.) of the new ASP will be erected inside soundproofed buildings
(machine house, pump house). The anticipated preliminary construction methods result in a
transmission loss from the walls of ≥ 42 dB, roofs of ≥ 37 dB and the doors and gates of 22 dB
and 24 dB respectively. Noise levels from all the outdoor equipment, vehicular traffic as well as
the wash bay was taken into consideration in the assessment.
The results of the assessment show that the ASP will lead to the following sound pressure
levels at specific points within the area being developed on the Afrox property:
Point on site boundary
Sound pressure level
IP 1 (Southwest)
66 dB(A)
IP 2 (Northwest)
65 dB(A)
IP 3 (Northeast)
68 dB(A)
IP 4 (Southeast)
62 dB(A)
(The figures in the assessment attached in Appendix G shows the position of the identified points).
As shown above the noise levels at the fence line of the site should not exceed 70 dB(A) at any
point during the day or night; In accordance with SANS 10103:2008 (note 4) for industries
legitimately operating in an industrial district during the entire 24 h day/night cycle, L R,eq,d =
LR,eg,n = 70 dB(A) can be considered as typical and normal. As such the results of this report
demonstrate that the sound technical requirements can be fulfilled with the planned design.
Furthermore the sound pressure level of 85 dB(A) at the working areas will not be exceeded.

Affairs?
If yes, please submit the necessary application to the Department of Water Affairs and attach
proof thereof to this application if it has been submitted.
13.
ENERGY EFFICIENCY
Describe the design measures, if any, that have been taken to ensure that the activity is energy
efficient:
This refrigeration cycle requires a large amount of energy to work; this energy is provided by
the compression of the air at the inlet of the unit. For improved efficiency the proposed ASU
includes an expansion turbine for cooling; the output of the expander helps drive the air
compressor. In addition, the cold equipment has to be kept within an insulated enclosure
called a ‘cold box’ to maximise efficiency.
For reasons of energy efficiency and to minimize heat input into the system all parts with
cryogenic liquefied gases are insulated with a state of the art cold insulation system.
All compressors of the air separation plant will be driven by medium-voltage motors.
For refrigeration in the ASU turbines are used, in which the gas is expanded. The turbines are
coupled with a compressor and an electric generator. Thus, the released energy of the
expanding gas can be partially recovered.
The buildings of the new plant (i.e. machine house, pump house) will be insulated with 100 mm
mineral fibre board (Rg > 50 kg/m³).
The windows to the buildings will be glazed in order to improve heating and cooling efficiency
and additionally the parking areas will be covered; resulting in energy savings due to the
reduced operation of car air-conditioning systems.
Describe how alternative energy sources have been taken into account or been built into the
design of the activity, if any:

SECTION D: IMPACT ASSESSMENT
The assessment of impacts must adhere to the minimum requirements in the EIA Regulations, 2010,
and should take applicable official guidelines into account. The issues raised by interested and
affected parties should also be addressed in the assessment of impacts.
1.
ISSUES RAISED BY INTERESTED AND AFFECTED PARTIES
List the main issues raised by interested and affected parties.
The issues raised by Interested and Affected Parties (IAPs) on the Draft BAR can be summarised as
follows:
1. Power and water consumption requirements and power source;
2. Permits / licenses required (if any);
3. Waste products particular to this industry;
4. Identify design measures that will be incorporated into the design / operation of the plant to
improve efficiency and no contamination of water sources;
5. What technology will be used and how does rate environmentally to alternative technology;
6. Main operational risks associated with this type of industry; and
7. Cumulative noise levels.
Response from the practitioner to the issues raised by the interested and affected parties (A full
response must be given in the Comments and Response Report that must be attached to this report):
The response from the Consultant/Client to the listed issues on the Draft BAR were as follows:
1. Electrical requirements
 The plant will be connected to an 11 kV, 50 Hz substation by the NMBM and will require
approximately 4250 kW for operation.
Water requirements
 14 m³/h of potable water for make-up water.
No boiler or fuel burning appliance is required.
2. The application is for authorisation for the construction for storage and handling of a
dangerous good (Oxygen). As the proposed plant is to be located in the Coega IDZ a search
and rescue permit will be required for the clearing of the site. There is no evidence for the
requirements of any other permits/licenses.
3. Very small quantities of waste will be generated during the operational phase and are readily
accommodated within the existing waste management infrastructure within the Nelson
Mandela Bay Municipal area. Potentially small amounts of hazardous substances (e.g. oil rags,
oil cans, spent molecular sieve) will be disposed of at an appropriate classified waste site.
4. Items included in the design to improve efficiency of the plant and to prevent contamination of
surface and ground water are provided in section 13 and section D-2 (Operational Impacts) of
the report (for a detailed response see the comments and response table attached as
Appendix E to this report).
5. The air separation plant will make use of the cryogenic air separation process with the use of
best available technology. The Linde Group, of which Afrox is a member, is a world leading
supplier of industrial, process and specialty gases. They have been in industry for 130 years
during which time they have made major technological advances which have resulted in the
increased efficiency of the process, as such no alternative technology is proposed.
6. A risk analysis (“HAZOP-Study”) will be performed for the entire operational system of the air
separation plant, in which the proposed measures against hazards are evaluated. The plant is
to be provided with safety-related monitoring and protection equipment as well as being fitted
with automatic shut-offs, emergency stop switches and spill kits. As a result dangerous
conditions such as excessive pressures, extreme temperatures and the accumulation of critical
materials or leakages will be prevented or contained.
7. During the feasibility study of the new air separation plant a noise impact assessment was
undertaken by the engineering office of IBAS. The results of the assessment show that the
noise levels at the fence line of the site should not exceed 70 dB(A) at any point during the day
or night; in accordance with SANS 10103:2008 (note 4) for industries legitimately operating in
an industrial district during the entire 24 h day/night cycle, LR,eq,d = LR,eg,n = 70 dB(A) can
be considered as typical and normal. As such the results of this report demonstrate that the
sound technical requirements can be fulfilled with the planned design. As the anticipated levels
are shown to be below 70 dB(A) at the fence line of the site the cumulative levels are not
anticipated to exceed the 70 dB(A) threshold; unless the sound levels form neighbouring
properties are in excess of the 70 dB(A) threshold at the border of their sites.

IMPACTS THAT MAY RESULT FROM THE PLANNING AND DESIGN, CONSTRUCTION,
OPERATIONAL, DECOMMISSIONING AND CLOSURE PHASES AS WELL AS PROPOSED
MANAGEMENT OF IDENTIFIED IMPACTS AND PROPOSED MITIGATION MEASURES
List the potential direct, indirect and cumulative property/activity/design/technology/operational
alternative related impacts (as appropriate) that are likely to occur as a result of the planning and
design phase, construction phase, operational phase, decommissioning and closure phase, including
impacts relating to the choice of site/activity/technology alternatives as well as the mitigation measures
that may eliminate or reduce the potential impacts listed.

Mitigation measures that may eliminate or reduce the potential impacts listed above:
N/A
CONSTRUCTION PHASE
Direct impacts
1. Noise Emissions
Background
Noise will result mostly from the increase in vehicular traffic on the roads to the site as well as from
the movement of vehicles and use of machinery (plant) for construction related activities. In all
likelihood the construction noise will have little impact on the surrounding community or
businesses, as it will most likely occur during the day when the ambient noise is louder and there
are unstable atmospheric conditions. Based on the timelines provided, the construction noise will
also be short lived as the construction phase of the project is expected to take less than two years
to complete.
Assessment
The significance of the impact resulting from construction activities is rated as VERY LOW (-ve) for
the proposed development as the site is classified as industrial with very low baseline noise levels
and it is not near any residential areas. With the implementation of mitigation measures the impact
can be reduced to INSIGNIFICANT.

2. Socio-economic impacts
Background
The project will result in direct investment into the economy, consisting of capital expenditure,
including engineering, procurement and construction; additionally approximately 200 - 300 job
opportunities will be created during the construction phase. As the plant is to be located within the
Coega IDZ, it is required to comply with the Zone Labour Agreement as provided by the CDC.
Assessment
Given the size of the local economy and the relative scale of investment during the construction
phase, the impact is expected to be of low intensity over the short-term period. The overall impact
is thus considered to be of VERY LOW (+ve) significance with the implementation of proposed
optimisation measures.
Not implementing the proposed development would mean that the potential for induced stimulus
on regional production, and associated secondary economic development would not occur. The
no-go alternative associated with this impact is expected to be of a VERY LOW (-ve) significance.

3. Removal of Indigenous Vegetation
Background
According to Mucina and Rutherford, (2006), the site falls within the Albany Thicket Biome with the
vegetation type of the area consisting of Coega Bontveld which is also known as Grass Ridge
Bontveld (Vlok & Euston-Brown, 2002). The distribution of this vegetation type is restricted to
shallow stony soils strongly influenced by an underlying calcareous substrate. The Coega
Bontveld has many Species of Special Concern (SSC), often in the form of small succulents and
geophytes. According to the FSR, of the proposed Kalagadi Manganese Smelter in Coega, a
previous study conducted on this vegetation type within the Coega IDZ by Dold (2002) reported
140 species, 19 of which are protected in terms of the National Forest Act and the Provincial
Nature Conservation Ordinance (PNCO). He also found one endangered plant and 10 species
endemic to the Albany Centre of Endemism. In his report, Dold recommended that 13 species
would need to be relocated from the Bontveld community (Coastal & Environmental Services,
2008). A list of SSC is provided in the EMPr.
Assessment
Clearing of the vegetation will occur but before this takes place a search and rescue process is to
be undertaken by a specialist to identify and remove species of special concern (SSC) (see list in
EMPr). As such the impact of the clearing of vegetation is considered a LOW (-ve) which can be
reduced to VERY LOW (-ve) with the implementation of mitigation measures.

 Before clearing takes place a search and rescue process is to be undertaken by a specialist to
identify and remove SSC (as identified by the CDC – see list in EMPr). The plants rescued off
the site are to be held in the CDC's nursery and reused in landscaping of the same site. In the
case that all of the rescued plants cannot be used in the landscaping of the Afrox site, then the
CDC will use these plants to rehabilitate identified sites within the IDZ (this will only be
confirmed on completion of the final designs).
4. Loss of Indigenous Fauna
Background
There is a general lack of pristine terrestrial habitats in the Coega region. This means that some
components of the terrestrial fauna have been severely impacted by previous human activity,
particularly the loss of vegetation, invasion of alien vegetation, local extinction of large mammals,
and varied industrial developments. However, despite the construction and development activity
within the IDZ the following fauna have been observed in area, these are namely; kudu, duiker,
steenbok, grysbok, tortoises, rabbits, jackal, mongooses, herons and numerous raptor species.
Assessment
Loss of fauna will take place owing to the loss of the habitat that will result due to the
establishment of the plant. Although the intensity is considered to be low the impact will be long-
term as the plant is not anticipated to be decommissioned in the near future. During the clearing
process care is to be taken so as not to harm fauna, including reptiles, should it be required a
specialist is to be called in to assist in the relocation. As such the impact is considered a VERY
LOW (-ve) impact, with or without the implementation of mitigation measures.

5. Impact on Heritage (Archaeology and Palaeontology)
Background
According to the Archaeological Impact Assessment of the greater Coega IDZ, undertaken by Dr
Johan Binneman in 2010, zone 3 has a well-developed infrastructure and at the time had several
large buildings already built while others were under construction. During the assessment the
occasional quartzite Middle Stone Age stone tools similar to those found in other zones of the IDZ
were found where pebble/cobble gravels were exposed, however these were not recorded. The
assessment identified that although the area/zones investigated were occupied extensively in the
past, the area is relatively poor in large and important ecological sites. It was noted that materials
may be covered by soil and vegetation and may only be exposed when development takes place.
Assessment
Based on the above there is a chance that archaeological remains/sites may be uncovered during
the clearing of the site. The impact is considered to be VERY LOW (-ve), however with the
implementation of mitigation measures the impact can be changed to a VERY LOW (+ve).

 If concentrations of archaeological heritage material, human remains or fossils are uncovered
during construction, all work must cease immediately and be reported to the Albany Museum
(046 622 2312) and/or the South African Heritage Resources Agency (SAHRA)
(021 642 4502) so that systematic and professional investigation/ excavation can be
undertaken; and
6. Dust emissions
Background
During the construction phase areas of vegetation and land will be stripped in preparation for the
construction process. During this phase areas will be left bare and the movement of large
machinery will result in the creation of dust.
Assessment
The intensity of the impact is rated as medium, primarily due to dust normally settling up to a
distance of 2 km from the source; however the duration is short-term. As a result, the significance
rating for the air impact on the receptors associated with the facility is VERY LOW (-ve), which can
be reduced to INSIGNIFICANT with the implementation of mitigation measures.

Mitigation Measures
 Dust suppression techniques, such as wetting or covering potential dust sources should be
implemented to minimise the impact of dust, when necessary;
 Construction vehicles must adhere to speed limits; and
 Prompt rehabilitation of cleared areas should take place to reduce exposure.
7. Waste Management
Background
The accumulation of solid domestic waste at any site can result in unpleasant odours and the
attraction of vermin (i.e. flies, rats etc.). Dispersal of these solid wastes, particularly nonbiodegradable items such as plastic and polystyrene, either by animals or wind can also cause
harm to animals if ingested or if they become entangled.
Assessment
A VERY LOW (-ve) impact is expected due to incorrect disposal of construction waste which could
lead to other visual impacts and loss of natural habitat. However, the probability of this impact
occurring is low if standard management practices are followed. Therefore, with mitigation the
impact is reduced to INSIGNIFICANT.

disperse to surrounding areas;
All personnel shall be instructed to dispose of all waste in the proper manner;
The Contractor shall identify and separate materials that can be reused or recycled to
minimise waste e.g. metals, packaging and plastics, and provide separate marked bins for
these items;
All construction materials (e.g. bags of cement) must be suitably stored and protected, so that
they do not become damaged and unusable;
The Contractor shall be responsible for the regular disposal (at suitable and licensed municipal
waste disposal facilities) of all waste generated as a result of the construction. Waste disposal
slips shall be kept for auditing purposes;
No dumping within the surrounding area shall be permitted, and no waste may be buried or
burned. Where potentially hazardous substances are to be disposed of, a safe disposal slip
shall be kept on record as proof of final disposal; and
General waste is to be collected either by the Local Municipality or via a Municipal approved
waste transporting contractor. The frequency of collections will be such that waste
containment receptacles do not unduly accumulate or overflow.
8. Traffic Impacts
Background
During the construction phase materials and equipment will need to be transported to site by
means of road transportation, resulting in more traffic utilising the CDC road network. Additionally
certain parts of the plant (e.g. the cold box and storage tanks) will be brought in from the harbour
already assembled; which could result in some abnormal loads being transported from the harbour
to the site during the construction phase – this will only be confirmed on final design of the
structures.
Assessment
Due to the relatively small size of the development as well as the short construction time (less than
one year) the intensity of the impact is considered low. It was also taken into consideration that
the traffic from / to the Afrox site will be concentrated through the Neptune Road / Cable Road
intersection; however since access to the area can also be gained from the R102, it is not
anticipated that the construction traffic will result in congestion of traffic in the area. It is also
anticipated that the construction traffic generated will not exceed the vehicle carrying capacity of
any of the affected roads in the area.
Based on the above the significance of this negative impact on the congestion at the intersections,
as well wear and tear of the infrastructure, is rated as INSIGNIFICANT, with no mitigation
measures proposed.

OPERATIONAL PHASE
Direct impacts
1. Safety Impacts (Risk of accidents in relation to the storage of dangerous goods)
Background
The entire plant site will be fenced; meaning any lawful access to the plant will only be gained by
authorisation with adherence to safety protocol. The ASU, storage facilities and associated
machinery are to be manufactured according to the relevant safety standards. The plant is
provided with safety-related monitoring and protection equipment. As a result dangerous
conditions such as excessive pressures, too high or too low temperatures, and accumulation of
critical materials or leakages can be prevented. Additionally the products are stored in double
shelled storage tanks so that in the case of any external incidents, if the external shell is punctured
the internal shell will remain intact.
There are management measures that will be implemented that are inherent in all of the
companies associated ASU’s, these include (but are not limited to):
1. A risk analysis (“HAZOP-Study”) is to be undertaken for the entire system, in which the
proposed measures against hazards are evaluated;
2. The plant is to be equipped with lights, and escapes routes from the systems are to be
clearly marked;
3. Regular maintenance of the machines is to be carried out.
The above form part of the design criteria for the plant and as such reduces the risk associated
with the plant.
Assessment
With consideration of the taken measures the significance is rated as a VERY LOW (-ve), no
additional mitigation measures are proposed.

2. Noise
Background
The noise impact assessment undertaken for the proposed plant shows that that the anticipated
noise levels at the boundaries of the property will not exceed the stipulated 70 dB(A). The noise
created from the machinery which operates 24 hours a day will result in an increase in the ambient
noise levels in the immediate vicinity; however as these are not anticipated to exceed the 70 dB(A)
threshold.
Assessment
The plant design has already taken into consideration the positioning of noise generating
equipment to reduce the noise levels at the boundaries and Afrox have also implemented
soundproofing of the structures housing noise generating equipment, as such the impact is rated
as a LOW (-ve), with no additional mitigation measures proposed.

3. Socio-economic impacts
Background
It is anticipated that the plant will result in approximately 20 job opportunities during the operation
phase (8 persons for transport-works and an additional 12 persons for plant operation).
Assessment
Although the intensity of the impact is low due to the small number of jobs required for the
operation of the plant, the period of the impact (25 to 30 years) results in the impact to be rated as
a LOW (+ve).

4. Contamination of surface water and ground water
Background
There is a potential for oil leaks from the compressors, hydraulic systems and transformers as well
as spills during maintenance. There is also the risk of diesel spills when filling up trucks at the
filling point as well as leaks from the storage tanks (above and below ground). However; the area
where the filling of trucks is to take place will be constructed out of an impermeable concrete slab,
and the above ground storage tanks, as well as equipment that could potentially result in spills or
leaks, are to be positioned within defined areas so as to contain any leaks or spills that may occur.
Additionally the underground diesel storage tank is to be manufactured of non-corrosive glass fibre
material, eliminating the chance of leaks.
Assessment
The significance of this impact is rated as a VERY LOW (-ve) which can be reduced to
INSIGNIFICANT with the implementation of mitigation measures.

Mitigation Measures
1. Use the minimum quantity of treatment chemicals necessary to achieve adequate system
protection;
2. Minimise leaks through preventative maintenance.
5. Traffic Impacts
Background
The plant is designed for the production of and distribution of products and not as an
administrative or sales base, therefore the only traffic that will be generated by the plant are the
employees, the distribution trucks and occasional service providers when required. The operation
of the plant requires approximately 20 employees throughout a 24 hour period, some of which are
shift workers. It is anticipated that the plant will require approximately 7 trucks per day, spread
throughout the 24 hour period, to fill up with products for distribution purposes. In a situation
where trucks have to wait to be filled, the plant layout has made accommodation for the on-site
parking of up to 6 trucks (excluding those being refilled or serviced), thereby eliminating the
chance of impeding the flow of traffic on the road outside the plant.
The ASP is located in Zone 3 of the IDZ, which is designated for light industrial development, as
such it is anticipated that each of the developments within the Zone will not have an exorbitant
amount of trucks making deliveries or collections. As it is an IDZ it is anticipated that the design of
the road infrastructure as well as the road network was done in accordance with required
specifications to handle the anticipated carrying capacity of the developed area on completion of
the IDZ. The addition of 7 trucks per 24 hours is not considered a large amount in terms of a light
industry development and as such should not interfere with the operations of other developments
in the Zone, and the other developments should not interfere with the operations of the Afrox plant
as the plant can be reached from two directions, minimising the chance of congestion.
Assessment
Based on the above the significance of this negative impact on the congestion at the intersections,
as well as wear and tear of the infrastructure, is rated as VERY LOW (-ve) due to the long term
operation of the plant, as such no mitigation measures are proposed.

6. Safety Impacts as a result of surrounding developments
Background
The Afrox site is situated adjacent to three other developments, of which the one stores Liquid
Oxygen. There are no inherent dangers of explosions from any of the existing adjacent properties.
However, if an explosion where to take place safety measures have been planned for to be put in
place on the Afrox site, these include (but are not limited to); double shell storage tanks, the layout
of the plant (i.e. being situated as far from the other developments as possible) and safety shutoff
valves.
Assessment
With consideration of the safety measures that are to be incorporated into the plant, the
significance is rated as a VERY LOW (-ve).

7. Noise
Background
The noise created from the machinery which operates 24 hours a day will result in an increase in
the ambient noise levels; as the anticipated levels are shown to be below 70 dB(A) at the fenceline
of the site the cumulative levels are not anticipated to exceed the 70 dB(A) threshold; unless the
sound levels form neighbouring properties are in excess of the 70 dB(A) requirements at the
border of their sites.
Assessment
The plant design has already taken into consideration the positioning of the plant on the site so as
to reduce the noise levels at the boundaries of the site and thereby reducing the combined sound
levels form neighbouring properties. As such the impact is rated as a LOW (-ve), with no additional
mitigation measures proposed.

The proposed activity is characterised by the separation of ambient air into the components Oxygen,
Nitrogen and Argon and the storage of these products. As per regulations Oxygen is listed as a
dangerous good and due to the proposed storage capacity of Oxygen on the site a Basic Assessment
is required.
It is evident from the above that the potential environmental and social impacts from the facility are of
low significance and should not influence a decision to approve the application.
