15.2 BMR
Bins are emptied on a daily basis and waste bags are taken to the airlock where Security
officers have to search through the bags. Security officers search these waste bags manually.
A separate hazardous waste bin is provided for broken glass at the Laboratory because it
creates a safety hazard for security personnel when mixed with general waste.
After leaving the airlock the waste bags are removed by the Production team to the different
waste telecon bins at the central waste facility area. If waste has to be sorted, appropriate PPE
must be used e.g. gloves and dust masks.
15.3 PMR
Management and control of the Waste Management Centre (WMC) remains the responsibility
of the Security Superintendent. No person is allowed to enter the area and remove any item
without permission of the Security Superintendent. Security standards shall be adhered to at
all times. No waste material will enter the Freight Centre after normal working hours or on
weekends except by prior arrangement. Only waste will be stored at the Skip Area. The
generator is responsible to separate all scrap before it will be collected by the Waste
Collectors to be transported to the Freight Centre, if waste is not separated correctly it will not
be removed. The person sealing the waste bag in the plant will conduct a visual check to
ensure no PGM’s are discarded into the waste bag / bin. The person sealing the bag should
capture the seal number, as well as his own details in the Seal Register. The seal is an
indication that the bag is full, a visual check has been conducted and is ready for collection. If
not sorted according to procedure, an environmental incident will be raised. Mop heads and
filter cloths from Level 2 (core production plants) must be separated from other contaminated
waste, and sealed in a separate waste bag as it is sent directly to MHD and not to the Freight
Centre. Mop heads and filter cloths from Level 3 (outside / services) are separated and sent to
the Freight Centre. All Level 2 waste is sent to the Central Plant Airlock (CPA) where it will go
through a goods scanner in order to ensure the waste is PGM free. Should any PGM’s be
recovered from the waste a sample will be taken for analysis and depending on the size of the
parcel, the rest will be returned to production. A security incident will be raised.
Security, in conjunction with the cleaners are responsible to remove all waste from the CPA to
the Freight Centre via forklift. All Level 3 waste is also separated according to the various
DOCUMENT NO. REVISION PRINT DATE PAGE
PD_ENV_001 19 2017/03/24 14 of 28

waste streams and transported to the Freight Centre via forklift. At the Freight Centre the
waste will once again go through a goods scanner to ensure the waste is PGM free. As a
return on investment items have been identified which could contain traces of PGM’s. These
are delivered to a Service Provider whereby the waste is reprocessed and the ash returned to
the PMR. All waste streams identified as possible PGM waste containing waste, is stored
within a dedicated storage area.
Items which cannot be washed out within the respective plants shall be escorted by a Security
Official to the Freight Centre whereby these items must be decontaminated within the
Decontamination Bay by the respective plant personnel under surveillance. The waste
generated from the washing activities within the Decontamination Bay will be returned to the
process, solid material is transferred to MHD and the liquor is pumped to RDD.
Items entering the Freight Centre should be of a reasonable size so that they can easily be
decontaminated (if need be) and placed into the respective waste skip. If there is a need to
dispose of items of a greater size, this will be done via prior arrangement with the Security
Superintendent who will be responsible for safe disposal. Where possible all recycle material
i.e. pvc, polypropylene pipe and lengths of steel, should be stockpiled for re-use where
possible.
Disposal of hazardous waste i.e. H/F containers etc. will continue as is current practice. These
containers shall be placed in clear plastic bag when empty; the bags are then sealed and
taken directly to the hazardous waste bin for safe disposal. Under no circumstance must the
cleaning of these containers be attempted.

1. Introduction The Western Platinum Refinery is located in Platinum Road, Vulcania, Brakpan Gauteng district
South Africa (Figure 1), approximately 1 km north of the N17 highway. The site lies at an
elevation of approximately 1640 m above mean sea level (ERM, 2008). The area is zoned
heavy industrial with the Refinery surrounded by a number of industrial complexes, informal and
formal residential establishments. The site drains in a south easterly direction towards a
tributary of the Klein Blesbokspruit. This tributary is characteristically a shallow reed and
bulrush-dominated non-perennial stream. The most prominent drainage in the area is the non-
perennial Klein Blesbokspruit which has its source approximately 2 km south east of the site
and drains in an easterly direction before joining the Blesbokspruit at a point roughly 10 km from
the site. The spruit is fed by a number of non-perennial streams which drain the residential
suburbs, agricultural lands and mining areas (ERM, 2008).
Figure 1.Location of the Western Platinum Refinery
The Western Platinum Refinery started operations in 1970, although it was officially opened in
1974, and has been substantially redeveloped in certain areas since then. The storm water
system has been added to and upgraded at various intervals during the life of the facility and is
4
constantly upgraded to comply with ever changing legal requirements and to reduce the impact
on the environment.
The four primary principles of storm water management as set out in DWAF’s Best Practice
Guideline for Storm Water Management (G1) (DWAF, 2006) is as follows:
1. Clean water must be kept clean and routed to a natural watercourse by a stream
separate from the dirty water system while preventing or minimising the risk of spillage of
clean water into the dirty water systems.
2. Dirty water must be collected and contained in a system separate from the clean water
system and the risk of spillage or seepage into the clean water systems must be
minimised.
3. The SWMP must be sustainable over the life cycle of the operation and over different
hydrological cycles and must incorporate principles of risk management.
4. The statutory requirements of various regulatory agencies and the interests of
stakeholders must be considered and incorporated.
These principles form the basis of the Western Platinum Refinery’s Storm Water Management
Plan.
This Storm Water Management Plan is outlined according to DWAF’s Best Practice Guideline
for Storm Water Management (G1) (DWAF, 2006):
Define the objectives of the storm water management plan (SWMP)
Technical situation analysis and evaluation
Conceptual design and review
Assess the suitability of the existing infrastructure
Define the infrastructure changes that are required
Undertake detailed design of all required infrastructure
Define operational, management and monitoring systems and responsibilities
Document the SWMP
Implement, manage and monitor the SWMP
Formally review/ audit the SWMP and systems at regular intervals.

R. Booysen / M. Jubileus
31/03/2014 15/02/2014
The Government Inspectorate visit conducted in November 2013 raised a number of concerns
surrounding the adequacy of the storm water management system, hence the need to revise
7
the storm water management plan. The following information was gathered and new objectives
were set:
During September 2008 ERM submitted a storm water design report. The existing storm water
system design was analysed to identify deficiencies and to evaluate the design compliance with
current legislation. The existing storm water system was analysed based on the design
requirements of the 1:50 year rainfall event and to evaluate the design compliance with GN704
legislation. Although this legislation is only applicable to mining, it was used for the purposes of
this evaluation as a best practice guideline. GN704 stipulates that clean and dirty water systems
must be separated and that one must not spill to the other more than once in 50 years. The
design approach adopted focuses on retaining the “first flush” of rainfall (usually the most
contaminated runoff from site) in a first flush retention dam. Further retention of storm water
on site will depend on the concentrations of contaminants within the storm water following the
first flush. The worst case design approach incorporates a second dam of equal capacity as
the first flush dam, to retain further contaminated discharge, and a final third dam of sufficient
capacity to retain the remainder of the runoff from the 24 hour 1:50 year flood event. Therefore
the first flush dam should be used as a temporary monitoring system to assess the quality and
quantity of the storm water leaving the facility. The total cost for the proposed design was
calculated at R 6 784240-32 (executed in a phased approach).
Table 2 (A & B): Calculations of current storage capacity vs. capacity required to store the 1:50 year flood event
Table 2A: Proposed design as follows:
First flush retention dam 600 m3
Second dam 600 m3
Third dam 4 500 m3
Total 5 700 m3
Table 2B: The current design is as follows:
Total bund & sump (55 m3) capacity 1 000 m3
Tank capacity (acid) 200 m3
Tank capacity (alkaline) 200 m3
Total 1 400 m3
Deficit 4 300 m3
8
The design report was not totally disregarded. During 2010/2011 the corroded concrete
pipelines were replaced with HDPE piping and HDPE welding. During 2013 the 20 m3 holding
tank for site run-off was removed and site run-off is now channelled to old D-Tank Farm (Table
2B). Although improvements were made, clean and dirty water are not separated and the
storage capacity to contain a 1:50 year flood is not adequate. During the investigation of an
uncontrolled discharge incident during December 2013, it was confirmed that the current design
(Table 2B above) is inadequate. In order to prevent future occurrences and to improve on the
overall storm water management on site the need to investigate and implement additional
measures was identified.

3. Technical situation and evaluation 3.1 Identification of clean and dirty areas Figure 2 indicates the areas identified as clean, moderately dirty and dirty. The Administration
block (including main Kitchen and Admin Canteen), Car Parks and Security area are classified
as clean. The Main Store, Projects and Rotable Stores, Security Offices, Training Centre,
Training Centre Canteen and Laundry are classified as moderately dirty. The Level 3 plant area
is classified as dirty. The Western Platinum Refinery is currently undergoing further studies
(Table 3, Item 1.4) inside the Level 3 plant area to determine the areas that have the most
significant effect on the quality of the storm water. These areas will be identified and mitigation
measures put in place to prevent contamination from entering the storm water system.
Figure 3 indicates the relationship between the clean, moderately dirty and dirty areas as well
as the flow of water into the receiving environment (in the event of an uncontrolled overflow).
The Klein Blesbokspruit is to the south east of the Western Platinum Refinery.

3.2 Existing water management infrastructure
Figure 2 indicates the current storm water flow and drainage from the Western Platinum
Refinery premises. The following areas drain into the storm water drains indicated in Figure 2
below:
Drain 1, 2 and 3: Runoff from MHD, Primary Separation plant and Main Change Houses,
(mostly drain 3).
Drain 4, 5 and 6: Runoff from the Laboratory, area for the new Incinerator, Freight
Centre, PM plant, Ignition (PMD), OPM plant, B/C Tank Farms, Bulk Chemical Storage
and partial Effluent Storage area. Run-off from the Main Stores / Training Centre reports
to drain 6 as well.
Drain 7: Runoff from the Chlorine Bay, Weighbridge and partial Effluent Storage area.
Drain 9: Runoff from the Training Centre Laundry (minor washing taking place), Training
Centre Canteen, Change House and Car Park.
Drain 10: Runoff from Project Store and Car Park in front of Main Stores and Training
Centre buildings.

Storm water bund and tanks
13
The Western Platinum Refinery has identified and classified the old effluent dams (between
drains 6 and 7) as contaminated land and is currently waiting on a Remediation Order.
Runoff from drains 1-7 report to a 1000m3 concrete sump where the pH and electrical
conductivity of the water is tested. Runoff from drains 9 and 10 is considered moderately dirty
water and pumped to the effluent storage tanks for disposal to landfill.
The physical characteristics of the storm water management infrastructure are as such:
Storm Water Drains: 525mm and 700mm concrete drains as indicated in Figure 2
(drains 1-10) located inside Level 3 and the Training centre. The majority of these
pipelines were replaced in 2013 (Table 1).
Ekurhuleni storm water system: Located to the south east of the Western Platinum
Refinery. This storm water system transports storm water from upstream and in the
event of an uncontrolled overflow from the Refinery, towards the Klein Blesbokspruit.
Bunded areas: Areas storing chemicals or tanks containing chemicals in Level 3
(indicated as the “Dirty” area in Figure 3) are bunded. These bunded areas require
upgrading as there are signs of corrosion and cracking.
Storm water sump and water quality monitoring equipment: A 1000m3 storm water sump
receives all storm water from the storm water drains in Level 3 (dirty water area) as well
as a portion of storm water from the Training Centre (moderately dirty). The quality of the
water (electrical conductivity and pH) is tested. The water is pumped to the two 200m3
contaminated run-off tanks. From these tanks the contaminated water is pumped to D
Tank Farm for removal by a contractor for disposal to landfill.
The majority of the surface area of the Western Platinum Refinery is covered by paving, cement
or grass, therefore the contribution to erosion is minimised.
4. Conceptual Design, Review, Changes required and suitability of existing infrastructure
ERM (2008) conducted a Storm Water Management assessment on the design of the Storm
Water Management infrastructure in 2008 which highlighted the following issues (ERM, 2008):
14
The existing storm water system design was analysed to identify deficiencies in the system, and
to evaluate the design compliance with current legislation. The existing storm water system was
analysed based on the design requirements of the 1:50 year rainfall event, and to evaluate the
design compliance with current Government Notice 704 (GN704) legislation. The proposed
revised storm water system layout and design was discussed with Lonmin and the system
layout and design was revised to incorporate these comments. Details of the design are
discussed more fully in Section 6.
An analysis and a design check were performed on the existing system to determine the
deficiencies in the current system. The peak flows at each sub-catchment for both storm water
channels and storm water pipes were calculated using the rational runoff modelling program.
This design check was done using the 1:50 year flood event as prescribed by the Red Book
guideline document for industrial areas. The analysis indicated that some of the pipes are
inadequately sized to accommodate the 1:50 year flood event, and the pipes require increased
diameters in order to accommodate the design flows (discussed in more detail in Section 6).
The analysis also indicated that the existing channels can accommodate the 1:50 year flood
event. The existing channels only require upgrading where corrosion has occurred. The design
calculations also indicated that storm water may pond during rainfall events in the area of
manhole MH3 and manhole MH4. This known ponding problem was confirmed by Lonmin’s
PMR staff. GN704 stipulates that clean and dirty water systems must be separated, and that
one must not spill to the other more than once in 50 years.
The PMR facility does not have separate clean and dirty storm water systems, and the
separation of these two systems will require substantial investment from Lonmin to re-engineer
the facility’s bunded areas, dust collection and mitigation measures, road, plant, and building
drainage systems, etc. Therefore the design has assumed the entire facility contains dirty water.
It is good practice to design future upgrades to the facility with the ability to separate dirty water
from the clean water system. The storm water must be treated if required to ensure the
concentrations of contaminants present in the storm water discharge off site complies with the
screening levels for contaminants specified by Ekurhuleni Municipality (included in Annex E).
Best practice storm water management principles advocate the inclusion of treatment of
contaminated storm water before off site discharge because sites should retain their wastes
close to the source rather than discharging to the receiving water body downstream. ERM
understand that Lonmin are currently underway with a water treatment project which should
15
include the ability to treat contaminated storm water stored on site, prior to discharge to the
municipal storm water system. South African legislation requires that the industrial discharge of
storm water off site to the municipal storm water system must occur under the conditions
stipulated in a Water Use License. Therefore a Water Use Licence will be required for the
discharge of storm water off site, and the permit would be issued subject to the facilities storm
water quality meeting the stipulated water quality standards. The application for the Water Use
Licence must be submitted by Lonmin. The application can be supported by the following
documents:
Drawing number PGT421/804/5/2 (Annex B); and
Design analysis results (Annex C).
The following clarifications and assumptions apply to the work performed:
The upgrade to the storm water infrastructure considers the current layout of the
PMR facility only, and does not include future planned upgrades to the facility
(such as the D tank farm relocation, or any projects to control dust generation on
site).
ERM understand that there is currently little control of contaminated dust
generation and dispersion on site, therefore limiting the ability to declare areas of
the site as “clean” storm water areas. Should Lonmin undertake a project in the
future to prevent contaminated dust dispersion on site, this will materially impact
the design of the storm water system (note that the effect of Lonmin undertaking
a dust control project will not render the storm water system ineffective, it will
merely result in the storm water system design being conservative and the
system will process more storm water than would be required).
As indicated in section 2, the Western Platinum Refinery has implemented changes to deal with
some of the issues identified above. The 2014 objectives address the upgrading of the Storm
Water Management infrastructure as the current infrastructure it is not adequate to store the
1:50 year flood event (Table 2B) and is also not compliant to all legal requirements (GN704 and
Section 21 of NWA). Table 3 outlines the actions / objectives in order to get Western Platinum
Refinery to a point where it will achieve both goals.
A number of alternatives (identified in Table 3) are currently being considered such as treatment
of storm water for re-use in the process. Should additional storage for storm water be required
after these studies have been completed, the re-instatement of the old effluent dams for storage
of storm water should be considered. An audit has also been conducted inside Level 3 (dirty
water area) in order to determine possible sources of pollution, which impacts on the quality of
16
the storm water. The outcome of this audit will determine mitigation measures required in order
to isolate these areas from the storm water management system, hence improving on the water
quality of the storm water runoff.
The current infrastructure has proven inadequate to store storm water during extreme rainfall
events such as that of December 2013 and January 2014 where discharge incidents were
reported to the Department of Water Affairs.
The other inadequacy identified is that contaminated areas in Level 3 could be contributing to
events where storm water is not within the specifications of the Klein Blesbokspruit Catchment
guideline. The accuracy of the automatic water quality monitoring system will also be assessed
(pH and electrical conductivity).
Table 2A&B indicates the volumes of storage capacity required versus the capacity required in
order to contain a 1:50 year flood. This calculation indicates a 4300m3 deficit of storm water
storage capacity on site.
Once these studies have been completed, the Western Platinum Refinery will obtain detailed
designs of the required infrastructure.
5. Operational, management and monitoring systems
The existing storm water system is inspected daily for any irregularities such as issues with
pumps, the electronic water quality monitoring system and the level of the storm water sump.
These inspections are conducted by the relevant operational personnel. Quarterly storm water
quality monitoring takes place by a third party consultant in order to determine compliance with
the Klein Blesbokspruit Catchment Guideline. Rainfall monitoring also takes place on site.
Monthly Environmental Officer inspections are conducted to ensure that the storm water
management system complies with legal and ISO14001 standards.
Emergencies are dealt with as per Lonmin’s ISO14001 procedure PD_SHEQ_SYS_011 -
Emergency Preparedness and Response.
Any irregularities reported during these inspections or during emergency events are reported
and tracked as per PD_SHEQ_SYS_014 - Non Conformity Corrective and Preventive Action.

6. Revision of this document
Revision of the Storm Water Management Plan should take place at least annually after an
audit of the Storm Water Management Infrastructure has been conducted. This will take place
for the first three years, where after such revision will take place every two years. If significant
changes occur on site, a revision of the SWMP will also be required.
