      A.1.        INTRODUCTION AND BACKGROUND

                  KV3 Engineers was appointed by Assmang Ltd to investigate the slag disposal facility and
                  plan and design a new slag disposal site and to apply for a waste licence for the
                  construction and operation thereof at their Cato Ridge Manganese Smelter plant in the
                  KwaZulu Natal Province near Pietermaritzburg. Various activities take place on the site
                  and a permit was issued for the dust storage and slimes dams to the south of the site and
                  an exemption given to store processed slag for use as aggregate. An EIA (attached to the
                  report as Annexure A) was done by Geomeasure and a Record of Decision (RoD) was
                  also issued for the establishment of an extended slag disposal facility to the north of the
                  site. Below is a schematic illustration of the process activities and related inputs and
                  product outputs at the Cato Ridge Manganese Smelter plant:

A.2.        SLAG PRODUCTION AND DISPOSAL

             Slag is produced in the furnaces as a waste product of smelting of a mixture of ore,
              reductants and some fluxes.           Molten slag is tapped into pots which are then
              transported by slag haulers to a processing location on the site.

             The slag is poured over an incline at the slag cooling area into trenches. When the
              slag has cooled down sufficiently and has solidified it is mined with loaders and loaded
              onto trucks for transportation to crushers at the Metal Recovery Plant (MRP) where it is
              crushed to a small size and reprocessed to remove more metal. The MRP is situated
              immediately north of the historic slag dump area.

             Slag is reprocessed in the MRP to remove residual metal which remained in the slag.
              The processed slag are then screened and washed and the suitable sizes used as
              concrete or cement block aggregate. The remaining fraction, which has no intrinsic
              value currently, is disposed of on the current slag dump.

             Slag is thus an inherent product of the smelting process. A typical slag would consist
              of residual oxides of manganese and iron together with the unreduced oxides such as
              lime (CaO), magnesia (MgO), alumina (Al2O3) and silica (SiO2).

             As described in the waste classification in section C of the report, the unusable slag is
              classified as hazardous and must be disposed of at a H:H facility. The purpose of this

                                                                                                     3
DEPARTMENT OF WATER AND ENVIRONMENTAL AFFAIRS

              waste licence application is to authorise the new proposed Class H:H slag disposal
              facility and to construct and operate the site in accordance with the design (to be
              approved by the authorities) and operational plans which are submitted as part of the
              application.

A.3         BACKGROUND AND STATUS QUO (Slag)

            A.3.1    Current slag dump

             Since the establishment of the smelter facility at Cato Ridge, the slag which had been
              produced was disposed of at the historic slag dump. When the slag dump was started
              in the 1950s, no legislative requirements existed to regulate the management of such a
              facility.

             There will always be slag production at a ferro-manganese production facility since ore
              contains only at best 48% manganese.

             The ratio of slag to metal usually varies between 0.8 and 1.2, given typical South
              African manganese ores.

             Slag is inert and does not generate gasses or leachate. Only under certain chemical
              conditions such as very high or low pH can elements be dissolved from the slag and
              washed out by water. At Cato Ridge such conditions do not occur.

             It is therefore of great importance that the management of slag at the facility be looked
              at holistically and includes historic, current and future slag production and management
              at Assmang Cato Ridge.

             To this end Assmang has appointed KV3, in conjunction with various other specialists
              and personnel from Assmang (SHEQ, production and materials management), to
              propose a slag management plan that will ensure responsible “cradle to grave”
              management of slag.

             Due to the fact that the current slag dump is not lined or permitted it was proposed to
              construct a properly designed slag disposal facility to the North of the existing slag
              dump and an EIA has been done and a RoD received for that as indicated under
              section A1.1 (c)((reference no: EIA/6804).



                                                                                                     4

            The plant, when in full operation, currently produces about 32 600 tonnes of slag per
             month.

            The MRP plant processes up to 52 000 tonnes of slag per month, which means that
             some processed slag is returned to the historic slag dump area.

            The processing of slag through the MRP and production of aggregate will consume a
             significant component of the total historic slag on site.

            The construction industry can only use a specific quality and size range of washed slag
             as aggregate for concrete or block making, and the unsuitable fraction has to be
             discarded.

            It also happens in the course of normal handling of slag during operations that small
             quantities of the slag are mixed with soil or other waste material on the site, which then
             make it unsuitable for processing through the MRP and reuse as concrete aggregate.
             Such slag has also been discarded on the historic slag dump.

              Current slag dump

              The current slag dump consists of slag that has been placed on the site over more than
              fifty years. Some of the slag has been reworked already and does not possess any
              commercial value at this time. Some of the slag has also been contaminated with soil and
              has no value as it stands. The fact that the dump is inert in the absence of water (see
              Annexure K: Potential Leachate Testing Report) and the possible negative
              environmental impact of moving such a large amount of slag has informed the decision to
              shape the unusable slag and cap it to prevent any ingress of water. A separate waste
              licence application report has been compiled for the decommissioning of the existing slag
              dump and will be submitted to DEA simultaneously with this application for the proposed
              new slag disposal facility.

         A.4.2         Other waste generation at Assmang

              Other waste that is generated at the site is disposed of at Shongweni landfill, the waste is
              listed below. This waste is not for disposal on site and does not form part of this

        A.4.3       Classification of Proposed Slag Disposal Facility

          The classification of the proposed slag disposal facility has been undertaken using the
          DWAF guidelines provided in Section 3 of the Minimum Requirements for Waste Disposal
          by Landfill, as well as the Minimum Requirements for the Handling, Classification and
          Disposal of Hazardous Waste, 2nd Edition, 1998. This classification is based on the type
          and tonnage of waste to be disposed of and the climatic water balance of the area under
          consideration.


        A.4.3.1     Waste Stream

          The proposed slag disposal facility will accept only slag generated on site. From the
          information on the slag currently generated, the slag can broadly be described as slightly
          alkaline, manganese rich gravel that exhibits no other hazardous characteristics other
          than potential leachate toxicity under certain conditions of pH that are unlikely to occur
          under natural conditions.        Chemically the slag comprises mostly calcium, silica and
          manganese in a slag oxide form. Under the Toxicity Characteristic Leaching Procedure
          (TCLP) conditions only manganese and aluminium are present in the leachate at levels


                                                                                                        7

ASSMANG CATO RIDGE WASTE LICENCE APPLICATION FOR PROPOSED NEW SLAG DISPOSAL FACILITY


          greater than acceptable risk figures (according to the WHO drinking water standard) for
          these elements. The slag is classified as Hazard Rating 2 under TCLP conditions and
          hence the site is classified as a Class H:H site.


        A.4.3.2     Generation Rate

          The current waste generation rate of approximately 32 600 t/month represents an
          approximate maximum deposition rate of 1 087 t/d that will be disposed of at the proposed
          new slag disposal site. In general only slag that has been processed at the MRP and
          cannot be used will be disposed of on the new slag dump, so under normal operating
          conditions a much smaller quantity of slag than mentioned above will be disposed as part
          of the processed slag are supplied to the construction industry for use in concrete
          products.


        A.4.3.3     Conclusion on Site Classification

          Based on the waste data and climatic water balance, the proposed slag disposal facility
          will be classified as H:H with the potential to generate leachate requiring management.
          (Refer to Section C for Geomeasure EIA report, Annexure A)



A.5.      DEVELOPMENT OF THE SITE
          With respect to this application the following activities are included:

                 The phased construction of a new lined H:H slag disposal facility with a capacity of
                  830 000 m3 and footprint of potentially 42ha to the north of the historic slag dump.
                  The facility will be developed in cells in line with the Design, Annexure G.

                 The processing and storage of all the slag from the furnaces at the new planned
                  slag management facility in line with the Slag Dump operations plan (Annexure J).

                 The processing and storage of all the slag from the upgraded slag processing
                  facility.

                 Disposal of surplus processed slag emanating from the MRP,




                                                                                                    8

                 “Clean” storm water will be diverted around the site being developed by a drain
                  system, the drain will be constructed with a “clay cut-off key” below ground level to
                  prevent ingress of ground water underneath the dump site below ground on the
                  perched water table level.

                 All “dirty” (potentially impacted) water on the disposal site will be collected via an
                  on-site drainage systems and diverted to the planned lined collection dams where
                  the water will be treated at the proposed storm water treatment facility, for reuse in
                  the smelter plant.

                 The infrastructure, drainage and fence at the new slag dump, will be maintained on
                  a regular basis,

                 The slag dump will be developed in a phased manner and once a section is full it
                  will be closed and the site will thus be progressively rehabilitated as per an
                  approved capping design,

                 The final rehabilitated areas will be planted with local grass and plant species to
                  prevent erosion via wind or water.

B.1.      APPLICANT

          The slag disposal facility (landfill) falls under the jurisdiction of the Ethekwini Municipality
          and the property belongs to Assmang Ltd Cato Ridge.


          The person responsible for Waste Disposal Services and the operation and management
          of the Slag Disposal Facility at Assmang at this stage will be the Senior General Manager,
          who is currently Mrs Princess Thwala.


          The consultant responsible for the design, licensing and management of the slag disposal
          facility is KV3 Engineers (Pty) Ltd.


          The consultant responsible for the Environmental Impact Assessment process is
          Geomeasure Environmental Consultants.


          The consultant responsible for the geohydrological study is also Geomeasure
          Environmental Consultants.



B.2.      SPECIAL MEASURES

          Storm water cut-off drainage will be constructed on the upside of the footprint of the site to
          ensure that all “clean” storm water is directed around the site that falls in the catchment on
          the upstream side of the site. The cut-off drain will be constructed with a “clay cut-off key”
          below ground level to prevent ingress of ground water underneath the dump site below
          ground on the perched water table level.


          Groundwater monitoring boreholes downstream of the proposed slag dump have been
          installed and will continue to be monitored on a regular basis. During each monitoring
          occasion, background groundwater monitoring (in boreholes up gradient of the slag dump)
          and investigative monitoring (in boreholes down-gradient of the slag dump) will be done,
          to determine any impacts of the slag dump on the ground water regime.

                                                                                                       11

B.3.      PUBLIC OPINION

          Meetings were held with the following relevant authorities regarding the licensing of the
          proposed slag disposal facility and its location:

                   Department of Water Affairs & Forestry (DWAF),
                   The Department of Agriculture and Environment Affairs (DAEA),
                   Department of Environmental Affairs and Tourism, (DEAT)
                   Ethekwini Municipality.

          As part of the EIA, a public participation process was undertaken. Additional meetings
          were also arranged with DEAT where the proposed facility was discussed. The public
          participation is covered in the Geomeasure report that forms part of this application.



B.4.      GEOLOGY AND GEOHYDROLOGY

          GEOHYDROLOGY AND AMBIENT GROUNDWATER QUALITY


          The two lithologies underlying the peninsular landform and study area differ vastly in age
          and composition and two intrinsically different groundwater regimes operate beneath the
          slag dump.



        B.4.1       Natal Group

          The Natal Group represents a secondary or fractured rock aquifer which comprises a sub-
          horizontally bedded widely jointed “brittle” rockmass of about 40 - 60 m thick. This
          formation has negligible primary porosity and permeability and most groundwater storage
          and movement occurs within joints, fractures or bedding planes within the rock mass.
          Groundwater recharge within this elevated and exposed study area is totally rainfall
          dependent and can only gain access into the rock mass via the joints and fractures in the
          rock mass. Recharge is however limited to remnant pore-water absorbed by the sandy
          subsoils, which is not lost to the atmosphere via evaporation or evapo-transpiration. This
          recharge would be minimal and is estimated to be less than 2 % of MAP In areas of
          intense fracturing, which is normally associated with “brittle deformation” of the rock mass
          in close proximity of faults or dolerite intrusions, the joints are often dilated and “clean”


                                                                                                    12
DEPARTMENT OF WATER AND ENVIRONMENTAL AFFAIRS

          and these localised, highly permeable zones offer preferential groundwater flow paths
          which enhance recharge and rock mass permeability. Under ideal conditions borehole
          yields of up to 10 l/s can be obtained within these discrete fractured zones. The
          sustainability of these aquifers is a factor of rainfall recharge and aquifer through flow.
          However, in this study area, aquifer through-flow is insignificant due to the elevated and
          isolated nature of the geohydrological environment. The KwaZulu-Natal Hydrogeological
          Map for Unit 2, prepared by Groundwater Consulting Services, depicts this as an area of
          poor groundwater development potential with expected borehole yields ranging from 0.5 -
          1 l/s. Mean EC values range from 30 - 100 mS/m, and although the groundwater generally
          meets with most of the recommended limits of the SABS 0241 (1984) Standards for
          Drinking Water, the water is often slightly acidic and may contain high levels of iron and
          manganese, which detracts from the suitability of this source for domestic and industrial
          use. The groundwater gradient on the plateau area is very mild and mirrors the surface
          topography. This gradient is influenced by the bedding of the formations and proximity to
          the edge of the escarpment where localised steep gradients and changes in regional flow
          direction may occur.



        B.4.2       Maphumulo Granite

          Un-weathered granite is usually quite massive and as a result this formation is considered
          a marginal secondary or fractured rock aquifer. The unconformable sandstone/granite
          contacts is generally quite “tight” but as a result of the significant age difference (>1000
          million years) between these stratigraphic units, isolated thin zones of weathering occur
          sporadically below this contact zone to offer inter-granular storage and enhanced
          permeability. Boreholes drilled to intersect this contact zone usually produce yields
          ranging from 0.1 – 0.3 l/s. Geological reconnaissance carried out in the Nagle
          Dam/Reservoir Hills transfer tunnel has also shown that the granite/dolerite contact zones
          are generally quite tight due to “welding”. The groundwater gradient in this stratigraphic
          unit normally mirrors the surface topography and a spring line occurs at the foot of the
          sub-vertical cliff faces where the sandstone/granite contacts are day-lighted.




                                                                                                   13

B.5.      MONITORING

          Assmang has a continuous water quality monitoring plan where monitoring is done on a
          regular basis by outside specialist companies according to a monitoring plan which has
          been approved by DWA. See Annexure C for a copy of the Water Quality Monitoring
          Plan. KV3 Engineers has also been appointed to assist with the management of the
          operation of the slag dump and will as part of their responsibilities do continuous
          monitoring of the operations. Assmang will appoint an external company to do yearly
          independent audits of the site.            Assmang also have rigorous internal monitoring
          procedures as part of their SABS 14 000 certification.


          A Monitoring Committee of external stakeholders has already been established for
          monitoring as required in the permit for the slimes dams and dust disposal facility. It is
          proposed to broaden the scope of the existing monitoring committee to include monitoring
          of the new slag dump. Quarterly reports on the water quality and operations will be
          submitted to the Monitoring Committee.



B.6.      GROUNDWATER

          According to the South African Aquifer System Management Classification (CSIR, 19954),
          the deep aquifer is classified as a minor aquifer system. The depth to groundwater on site
          varies over the site, from 11.4m to 35.61m. For more detail refer to the Conceptual
          Hydrological Site Model attached in Annexure B. Although the existing slag dump has
          been operated for over 50 years, ongoing groundwater monitoring has demonstrated that
          no significant pollution of the deep aquifer has taken place. The threat to the groundwater
          will further be reduced as the existing dump will be worked away and the remaining
          portion capped.       The proposed new slag disposal facility will be properly lined in
          accordance with the design requirements for a Class H:H facility.


          All water, ground and surface, from higher laying properties is currently captured and
          diverted around the site and all the ground water that flows through the site along the
          perched water table is captured and will not leave the site. Drainage will be upgraded to
          include the new slag dump to ensure that these measures remain in place. The captured
          water will be used at the plant to reduce the demand on potable water.



                                                                                                  14
DEPARTMENT OF WATER AND ENVIRONMENTAL AFFAIRS
ASSMANG CATO RIDGE WASTE LICENCE APPLICATION FOR PROPOSED NEW SLAG DISPOSAL FACILITY



B.7.      REHABILITATION

          Rehabilitation will entail the capping of the slag dump as per the Closure Design
          Requirements set out the Minimum Requirements for Waste Disposal by Landfill
          document and the re-establishment of the natural plant growth in the area. Excessively
          rocky and other undesirable cover material will be removed. The top soil will not be
          compacted so as to allow natural settling of soil. The site infrastructure established for
          construction (such as offices, workshop areas and storage facilities) will be removed once
          construction is complete. All packaging material, danger tape and temporary markers,
          fences, etc. used for construction purposes will be removed (Refer to the EMP in
          Annexure H for further details).



B.8.      LAND-USE AND ZONING

          The land is already zoned for industrial activities and no change in zoning is required for
          the establishment of the new slag dump (extension of the existing slag dump).



B.9.      OPERATION

          The operation of slag processing from the furnace to the placement of the processed slag
          on the slag disposal site is captured in the slag operational plan that forms part of the
          application in Annexure J.


          The slag is tapped, transported to the slag cooling facility and left to cool. Sufficient
          capacity is provided at the slag cooling area to allow slag to cool before it is excavated for
          processing at the MRP. The excavated slag is taken to the MRP and once it has been
          segregated into metal, aggregate and unusable product, the metal is returned to Assmang
          for sale into the market, the aggregate is sent to a company that sells the aggregate for
          mixing in concrete and the leftover fines are taken to the slag dump.




                                                                                                     15

B.10. HEALTH AND SAFETY

          Cato Ridge obtained OHSAS 18001 certification on 4 October 2006 and has maintained
          certification since. Continued OHSAS certification requires commitment to high standards
          and continued improvement on all aspects of health and safety management.


          In line with legislation, Cato Ridge Works performs medical surveillance on employees in
          accordance with their potential risk of exposure. Employees undergo induction training at
          the start of employment and thereafter at least annually. The induction training identifies
          and creates awareness of the potential risks to health and safety of employees as well as
          the management systems and mitigation measures implemented by the Works.


          In addition, job-specific training is scheduled throughout the year together with detailed
          health & safety awareness training such as first aid, fire fighting, waste management, etc.
          The SHEQ department also coordinates the implementation and management of an
          emergency preparedness and response plan for the site.


          Occupational hygiene surveillance is performed to quantify hazards that e.g. noise and
          dust poses to employees. Areas are classified accordingly and employees are provided
          with appropriate PPE (personal protective equipment) for their protection. The use of PPE
          in designated areas is compulsory. .



B.11. ENTRY AND SECURITY

          The slag dump is located within the Smelter plant complex and as such will be provided
          with the same standard of security and access control as the plant. An access gate with
          security personnel will control entry to the site, and the slag dump will be individually
          fenced where necessary to restrict access from outside the plant area, and internally to
          safeguard workers at the plant but also to suit the operational requirements. Fencing of
          the site with a 2.1 m high fence will take place to keep unauthorised persons out, and the
          fence will be maintained on a regular basis.


          All activities that are undertaken on the site fall within the secure boundary of the site. 24
          hour access control is enforced and personnel are not allowed on the site without the
          proper Personal Protective Equipment (PPE) and if they have not completed the required

          induction. The proposed new slag dump will fall outside the current perimeter fence but a
          new fence will be erected around the site that forms part of the existing perimeter fencing
          to ensure that access to the dump will be regulated.



B.12 ENVIRONMENTAL IMPACT ASSESSMENT

          The site was designed and the operational plan been drafted to ensure that the long term
          impacts of the site are minimised to inter alia control the ingress of surface and
          groundwater into the site and thereby limit the production of leachate.         Any leachate
          produced will be captured and treated. A detailed rehabilitation plan will be designed and
          implemented for the closure of the existing slag dump. The design and operation of the
          slag dump is provided and forms part of this application (Annexure G and J
          respectively). Implementation of (and auditing against) the EMP will ensure that any of
          the issues that relate to operational standards of the slag dump are addressed and the
          negative effects on the environment mitigated at all times.


          There is no threat to indigenous species as the footprint of the dust storage facility, current
          slag dump, MRP and related facilities are already in place and the proposed slag dump is
          situated on disturbed grassland with invader species. The possible hazardous effect of
          dust is negated by the fact that the nearest affected residents are 2 km’s from the site and
          due care will be taken to suppress dust as far as possible. Dust fallout from the plant and
          the ancillary activities such as the operation of the slag dump will be continuously
          monitored in line with the current Integrated Air Quality Monitoring Plan (IAQMP).


          The aesthetics will not be impacted as the site has been in existence for 50 years and its
          appearance will be improved with the rehabilitation of the existing slag dump.            The
          environmental impact of the proposed facilities is not considered to be significant and
          measures have been incorporated into the design and operational management plan to
          minimise any detrimental impacts.


          A draft Environmental Management Plan has been compiled and is attached in Annexure
          H. It must be noted that the EMP is still in a draft format and will be finalised once the
          Licence conditions are known.



                                                                                                      17

C.1.      SITE CLASSIFICATION
          The classification of the existing and proposed extended slag dump has been undertaken
          using the DWAF guidelines provided in Section 3 of the Minimum Requirements for Waste
          Disposal by Landfill, as well as the Minimum Requirements for the Handling, Classification
          and Disposal of Hazardous Waste, 2nd Edition, 1998. This classification is based on the
          type and tonnage of waste to be disposed of and the climatic water balance of the area
          under consideration.



C.2.      WASTE STREAM
          The existing and proposed dumps accept and will accept only slag generated on site. The
          slag can broadly be described as slightly alkaline, manganese rich gravel that exhibits no
          other hazardous characteristics other than potential leachate toxicity under certain
          conditions of pH that are unlikely to occur under natural conditions. Chemically the slag
          comprises mostly calcium, silica and manganese in a slag oxide form. Under the Toxicity
          Characteristic Leaching Procedure (TCLP) conditions only manganese and aluminium are
          present in the leachate at levels greater than acceptable risk figures (according to the
          WHO drinking water standard) for these elements.                The slag is classified as Hazard
          Rating 2 under TCLP conditions and hence the site is classified as a Class H:H site.



C.3.      GENERATION RATE

          The current waste generation rate of approximately 32 600 t/month represents an
          approximate maximum deposition rate of 1 087 t/d that will be disposed of at the proposed
          new slag disposal site. In general only slag that has been processed at the MRP and
          cannot be used will be disposed of on the new slag dump, so under normal operating
          conditions a much smaller quantity of slag than mentioned above will be disposed as part
          of the processed slag are supplied to the construction industry for use in concrete
          products.

                                                                                                       19

C.4       CLIMATIC WATER BALANCE

          Based on the Climatic Water Balance, Assmang is located in a water surplus area and is
          therefore (B+).



C.5       CONCLUSION ON SITE CLASSIFICATION

          Based on the waste data and climatic water balance, the proposed slag dump will be
          classified as Class H:H with the potential to generate some leachate that may require
          management.        (For more detail refer to Section C for Geomeasure EIA report,
          Annexure A).

                                               E.        OPERATING AND MAINTENANCE PLAN



E.1.      FACILITY AND RESOURCES

    When the slag dump was started there was no legislation governing the operation of such a
    facility. New legislation has however been promulgated and Assmang are implementing
    various projects to comply with legislation. Assmang have identified the operational
    management of the slag dump as one area for improvement and have set about improving the
    operations and developing a management plan for the slag dump.                     The detailed Slag
    Operational Plan is attached as Annexure J to the report.


    As a result of concern from DEAT the Environmental Management Inspectorate did an
    inspection in September 2007 and issued directives for Assmang to ensure future compliance
    with legislation at the smelter. As a result Assmang has appointed various specialists to make
    sure that operations comply with all the regulatory and statutory requirements.


    Assmang have identified the management of the slag dump and related operations as a prime
    area for improvement and are currently investigating where improvements can be made. The
    following describes certain of the improvements that form part of the investigation.


    The main access roads for the slag haulers will be a surfaced roadway with the minimum
    gradient to ensure that the haulers operate within the design parameters of the vehicles. All
    roadways will be properly maintained and dust suppression compound applied to relevant
    areas to ensure that dust is kept to a minimum.


    Once the first step of upgrading has taken place, the site will be managed according to an
    approved operational plan i.e. the cell method. Once cells have been filled to capacity, they
    will be capped and rehabilitated in line with the EMP by planting local grasses to minimise
    possible erosion.


    Drainage canals that capture storm water on the slag dump will be maintained at all times to
    ensure the effective disposal of any contaminated water to the proposed polluted storm water
    treatment facility.


                                                                                                     24

E.2.      ACCESS CONTROL

          The following measures will be implemented to ensure control over access to the slag
          dump:

                   Access to the site will be controlled to prevent unauthorised entry and illegal
                    dumping on the site.        It is proposed that responsible security personnel are
                    present at the slag dump during operating hours for access control and that after
                    hours the gate should be locked to ensure that no illegal entry takes place.

                   Security personnel will ensure that only slag that has been processed is allowed
                    on the site for disposal. No other waste products will be allowed to be disposed of
                    at the site.

                   The amount of slag disposed of at the site will be recorded (i.e. Tonnages).



E.3.      CONTROL OF NUISANCE


        E.3.1       Fires

          No fires will be allowed on the site therefore no special permission will be required. The
          slag that has been processed at the MRP is a non-flammable substance and cannot burn
          under any circumstances. There is a potential fire risk where molten slag is deposited but
          all vehicles will have the relevant fire fighting equipment and personnel will be trained in
          fire fighting procedures. The proper operation of the slag cooling area also ensures that
          empty and full slag haulers do not occupy the same stretch of road when depositing slag
          reducing the possibility of an accident. Personnel are also not allowed near the operation
          when the slag is being poured. Limiting access to the area also reduces the possibility of
          burns to personnel.


        E.3.2       Littering

         Since only slag, that has been processed at the MRP and has no further value, will be
         deposited on the proposed slag dump, littering will not pose any threat at the site. With
         proper access control to ensure that no other waste streams are deposited on the slag
         dump, littering will not be a problem at the site.

                                                                                                    25
DEPARTMENT OF WATER AND ENVIRONMENTAL AFFAIRS
ASSMANG CATO RIDGE WASTE LICENCE APPLICATION FOR PROPOSED NEW SLAG DISPOSAL FACILITY



          According to the waste management plan for the entire facility at Assmang, and the
          contract between Assmang and a waste management company, all other waste streams
          will be collected for disposal at an off-site landfill but the control will be done by Assmang
          Cato Ridge Works.


        E.3.3        Dust

          Unsurfaced roads and ungrassed or unpaved areas, which generate dust, are and will
          continue to be regularly watered to restrict dust generation to levels which do not pose
          any nuisance to personnel and other people at the facility or in the surrounding area.

          At all areas where there is a potential for dust generation, the areas are regularly watered
          to minimise dust. Assmang has also embarked on a dust minimisation programme where
          products such as Dustacide are used to bind dust to prevent it from being picked up by
          wind and deposited elsewhere. Treated water from the storm water treatment facility is
          used to ensure that the reliance on potable water is reduced without increasing the risk of
          contaminating groundwater.


        E.3.4        Noise

          Noise created by the operational activities is created by the material moving equipment
          such as:

                    Front End Loaders;

                    Excavators;

                    Haulage trucks,

                    Bulldozers;

                    Water Tankers,

                    LDVs

          Similar machines are operational at all times at the smelter plant next to the disposal site,
          so this operation will not have any new noise impact. There is also a significant distance
          to the nearest dwellings. Vehicles and equipment will be maintained to ensure that they
          are in a good operational condition and that the exhaust silencers are in a normal working
          condition for the type of equipment.

                                                                                                     26

E.4.      RECYCLING

          Slag is sent to the MRP for processing to extract the remaining manganese and to screen
          the waste slag into usable fractions of aggregate that can be used in the construction
          industry in concrete products. The MRP uses a hydro jigging process to separate the
          heavier manganese from the slag. The remaining slag is then screened into the different
          sizes for use as aggregate for concrete production.



E.5.      CONCLUSION

          The Slag Operations Plan will, when properly implemented and monitored, ensure that the
          slag is effectively and efficiently managed to minimise the impact of the facility on the
          receiving environment.




                                                                                                27

F.1.      ONGOING INSPECTIONS AND MAINTENANCE

          The waste stream will be monitored via visual inspection at the entrance to the slag
          dump.     A weighbridge is also in operation to ascertain the amount of slag that is
          generated. The amount that goes for sale, the amount of metal recovered and dust and
          slimes that are disposed of will also be measured. Details of the information that will be
          gathered are set out in the Waste Operational Plan.                   An employee will be made
          responsible for ensuring that all waste streams are monitored and also that only dust,
          slimes and slag is disposed of at the relevant facilities on site.



F.2.      DISPOSAL FACILITY AUDITING

          The slag disposal facility will be audited at least once per year or as prescribed in the
          licence conditions by an independent external auditor appointed by the licence holder.
          The audit frequency and procedure will adhere to the license conditions that will be
          stipulated by the DEA.



F.3.      WATER QUALITY MONITORING

          Water quality monitoring of the slag dump forms part of the overall monitoring of the
          Assmang operations on site. Water quality monitoring will be done biannually for the
          parameters prescribed in the licence. The four new boreholes which were drilled during
          the geohydrological investigation will be used for groundwater quality monitoring.
          Background water quality monitoring will be done during each monitoring occasion.
          Groundwater levels will also be monitored. The analysis and interpretation of results will
          be forwarded to DEA as will be required in the licence. Assmang have made adequate
          budgetary provision for monitoring of groundwater and leachate for the site.              The
          monitoring will be done in line with the approved monitoring plan. The monitoring program
          is reported on during Monitoring Committee meetings.




                                                                                                     29

F.4.      LEAK DETECTION MONITORING

          The lining system of the slag dump is equipped with a leak detection system. This system
          will be constantly monitored to ensure that if leaks occur the necessary remedial action is
          implemented to minimise impacts on the environment.




                                                                                                  30

            G.        PRELIMINARY REHABILITATION, CLOSURE AND END-USE PLAN



G.1.      REHABILITATION OF PROPOSED SLAG DUMP EXTENSION

          Once portions of the proposed slag dump extension has reached capacity, the cells will be
          capped and covered with a clay layer, an engineered lining and then additional topsoil to
          control dust and avoid possible erosion. The whole area will be grassed to ensure the
          minimum environmental impact. The rehabilitation will therefore be done in line with Class
          H:H Closure Requirements as set out in the Minimum Requirements for Waste Disposal
          by Landfill document, 1998 and as required by DEA in the licence to be issued. Assmang
          have established an initial estimate for the rehabilitation cost of R 25 000 000. It must
          however be noted that this is only a first order estimation and the final rehabilitation cost of
          the slag dump will only be done in the future towards the closure of the site. The plan is
          also to develop the site in a phased manner and to cap and close completed phases
          progressively as operations proceed.

          A continued monitoring plan also forms part of the operations of the site and at the time of
          closure further testing will be done to ensure that the correct methodology is applied.

                                           H.        CONFIRMATION OF FATAL FLAW CHECKS


The site was investigated to confirm that no fatal flaws, as set out in the “Minimum Requirements
for Waste Disposal by Landfill”, are present. A “N/A” (not applicable) noted against the criteria
listed below indicates that the situation does not prohibit the development of an environmentally or
publicly acceptable waste disposal facility.

1.        3 000 m from the end of any airport runway or landing strip in the direct line of the flight
          path. Alternatively, within 500 m of an airport or airfield boundary.

          N/A.

2.        Areas below the 1:50 year flood line.

          N/A.

3.        Areas in close proximity to significant surface water bodies.

          N/A.

4.        Unstable areas.

          N/A.

5.        Sensitive ecological and/or historical areas.

          N/A.

6.        Catchment areas for important water resource areas.

          N/A.

7.        Areas characterised by flat gradients, shallow or emergent groundwater.

         Yes, there is a shallow aquifer underlying the site, however special mitigatory
         measures forms part of the slag disposal facility’s design to prevent ingress to this
         shallow groundwater from the slag dump i.e. to ensure containment. These include
         the placement of an engineered Class H:H liner below the new slag dump (extension
         of old slag dump) to ensure containment of any water that may penetrate the slag
         dump. A monitoring plan has also been developed and the terms of reference for



                                                                                                   34

         the existing Monitoring Committee will be broadened to include the slag dump to
         ensure compliance to the relevant licence conditions.

8.        Areas characterised by steep gradients, where stability of slopes could be problematic.

          N/A.

9.        Areas of ground water recharge because of topography and/or highly permeable soils.

          N/A.

10.       Areas overlying or adjacent to important or potentially important aquifers.

          N/A.

11.       Areas characterised by shallow bedrock with little soil cover.

          N/A.

12.       Areas in close proximity to land-uses that are incompatible with landfilling and where the
          requisite buffer zones are not possible, or areas that may attract community resistance.

          N/A.

13.       Areas where adequate buffer zones are not possible.

          N/A.

14.       Any area immediately upwind of the prevailing wind direction(s) of a residential area.

          N/A.

15.       Areas, which because of title deeds and other constraints, can never be rezoned to
          licence a waste disposal facility.

          N/A.

16.       Areas underlain by servitudes preventing the establishment of a waste disposal facility;
          examples include Rand Water, Eskom or Road Department servitudes.

          N/A.

17.       Any area characterised by any factor that would prohibit the development of a landfill
          except at prohibitive cost.

          N/A.

                                                                                                    35
