SYNOPSIS Anglo American Inyosi Coal (Pty) Ltd (hereafter AAIC) proposes to develop an opencast coal mine, the New Largo Colliery, to supply coal to Eskom’s new Kusile Power Station that is currently under construction between Bronkhorstspruit and eMalahleni in the Nkangala District Municipality of the Mpumalanga Province.

The New Largo coal reserve lies within AAIC’s current prospecting right area / proposed mining right area. The total mining right area is 12 773 hectares (ha), of which the opencast mining area (mine pits) will occupy an area of approximately 5 600 ha. Both the No. 2 and No. 4 coal seams will be mined in two main phases:

Mining Phase 1 entails general construction, the development of the first opencast box-cut in the northern section of the mining area and the commissioning of the first dragline. Construction will commence in the second quarter of 2013 and mining operations are expected to commence in the first quarter of 2015. A truck and shovel fleet will be in operation until 2023. This coal is of such a quality that it does not require beneficiation. The coal in this area will therefore be dispatched directly from the tertiary crushing plants to the Kusile Power Station;

Mining Phase 2 construction will commence in the first quarter of 2020 and operations in the first quarter of 2023. This phase entails the development of opencast mining in the southern section of the mining area, commissioning of the second dragline in this section, as well as the commissioning of a coal processing plant. The water treatment plant (WTP) established during Stage 1 of AAIC’s coal supply to the Kusile Power Station (the Phola-Kusile Overland Conveyor), will also be expanded during this phase.

The colliery will be located in the B20F and B20G quaternary catchments of the Olifants River Water Management Area.

Various mining alternatives were considered in order to minimise environmental impacts while maximising the coal resource. Mine Plan Version 6 covers an area of approximately 5 600 ha and presents AAIC’s optimised mine plan on which this water use licence application is based. An alternative Mine Plan (Mine Plan Version 7d), was developed which excludes a section of the surface rights area in the north to avoid mining of the large pan on the farm Honingkrantz 536 JR and covers an area of approximately 4 800 ha. Most of the coal found in the northern part of the coal reserve is of high quality coal. The coal in the northern reserve is of good quality and reduces the challenges posed by Mine Plan Version 7d in terms of sequencing and blending of coal to meet the quality parameters for the Kusile Power Station. Mine Plan Version 6 will therefore ensure sustained supply of coal to the Kusile Power Station at the required quality. Financially, Mine Plan Version 6 is the preferred alternative, both in terms of capital expenditure and cost of coal to Eskom.

This document provides the detailed information in support of an Integrated Water Use Licence Application for the following water uses associated with the proposed mine (Mine Plan Version 6):

S21(a) Taking water from a water resource

Water for the construction phase, will be obtained from three boreholes drilled into the old New Largo Colliery underground workings. According to GN R399 dated March 2004 (as extended in GN 498 in Government Gazette 35477 of 28 June 2012) quaternary catchment B20F and B20G fall within Zone C. In this Zone, 75m3 of groundwater may be abstracted per hectare per property per annum. The boreholes are located on Portions 1 and 4 of the farm Klipfontein 566 JR, portions 1 (± 379 ha) and 4 (±159 ha). Therefore, 28 425 m3/annum and 11 925 m3/annum may be abstracted, respectively (total of 40 350 m3/a). These water uses were included in the Integrated Water Use Licence Application (IWULA) for the Phola-Kusile Overland Conveyor, and once authorised it will continue in terms of that license.

iii

During the construction phase (in June 2013), borrow pits will be developed at the box cut areas. The purpose will be for the removal of material for construction purposes and coal will not be exposed until mining commences in 2015. These borrow pits will be kept dry by pumping water from the borrow pits to a settling dam until coaling commences (also refer to S21(f), (g) and (j) water uses).

During the operational phase, water will be pumped from the old underground workings and from the advancing pit to ensure that mining activities continue (refer to S21(j) below).

S21(b) Storing water

Treated water from the WTP will be pumped to a 1 Mℓ potable water reservoir located at the WTP. From this reservoir, water will be pumped to a 250 kℓ elevated potable water tank provided as part of the Phola-Kusile Overland Conveyor. Water for Phases 1 and 2 of the New Largo Colliery will be provided from this elevated tank. An additional 1 Mℓ storage tank will be established close to the abovementioned reservoir during Phase 2 when the coal processing plant is developed. Potable water will gravitate to the reticulation system that supplies the buildings, workshops, offices, Tips 1 and 2 and the explosives magazine.

Potable water is required for dust suppression at the conveyor transfer points, as well as for dust suppression at Tips 1 and 2. This will be sourced from the elevated water tank and stored in tanks at the transfers and Tips.

Fire water will be sourced from two fire water tanks (420 kℓ each) next to the potable water reservoir. This will also be provided as part of the Phola-Kusile Overland Conveyor project and was included in the IWULA for the conveyor system.

S21(c) Impeding or diverting the flow of water in a watercourse and/or S21(i) altering the bed, banks, course or characteristics of a watercourse

A number of wetlands and other watercourses are present in the proposed mining area. These watercourses will be mined partially or completely, and/or will be altered due to the development of infrastructure in the vicinity, or within, the watercourses. Borrow pits will also be developed in the vicinity, or within, watercourses. This will result in the alteration of the characteristics of these watercourses.

S21(f) Discharging waste or water containing waste into a water resource through a pipe, canal, sewer, sea outfall or other conduit

Water (seepage and rain water) from the borrow pits developed at the box cut areas will be pumped to settling dams. Any suspended solids will be allowed to settle, where after it will be discharged into existing farm dams.

Treated water from the WTP will be re-used to meet the water demands of the mine (i.e. potable water, processing, dust suppression and fire water) and the remainder will be discharged back into the receiving catchment.

A preliminary assessment was done of the discharge points, based on surface water run-off considerations only and assuming proportional discharge amongst the affected streams. During this assessment, the proportional loss of catchment was determined at key stages in the life of mine. The proportional flow reduction was based entirely on the affected catchment areas (i.e. the assumption that the flow reduction will be directly proportional to the catchment area lost as a result of mining and mining related activities). A total of 16 discharge points were identified on this basis.

The final discharge volume and positions are, however, subject to the outcome of the Reserve Determination that is being conducted by Wetland Consulting Services (WCS). The expected date of completion is May 2013 and in light of the timeframes of the project and the issuing of the water use license, the preliminary discharge points are included in the IWWMP and IWULA.

iv

The Reserve Determination study will consider the Ecological Water Requirement (EWR) at key sites along the streams, close to the outlet of each of the preliminary identified Resource Units (RU’s), and will not provide details for each affected stream. The approach will therefore more likely focus on the combined discharge flows that will affect a particular EWR site downstream.

WCS has, however, indicated that the distribution of discharge volume amongst the preliminary positions referred to above makes sense from a mitigation perspective and the current understanding of the potential impacts on the water resources. The proposed approach is likely to reduce the flow volumes into each of the affected systems, thereby reducing the risks of erosion at any particular site. Furthermore, it serves as an attempt to restore some flow in those systems impacted by mining and dewatering in their watersheds. It may also have the added benefit of buffering water quality impacts across a wider front along the Wilge River and Saalklapspruit (reference: e-mail communication dated 30 May 2012).

Should the outcome of the Reserve Determination study result in changes to the preliminary list of discharge points, such changes will be addressed in an application for a water use licence amendment.

S21(g) Disposing of waste in a manner which may detrimentally impact on a water resource

Activities which may impact on the quality of the water resources are:

Settling dams/silt traps will be developed at the borrow pits developed at the box cut areas. Water removed from the borrow pits will be temporarily stored in these facilities to allow any suspended solids to settle out before the water will be discharged back into the water resource;

Overburden and topsoil dumps will be established in the north-west for the placement of spoils from the initial boxcut;

During the initial years, coal from the northern pit will be dispatched directly from the crushing plants to the Kusile Power Station and therefore no discard will be generated. In 2023 when Dragline 2 is commissioned, mining operations move to lower quality coal in the southern pit areas. The lower quality coal will need to be blended and/or beneficiated in order to ensure a consistent supply of coal to the Kusile Power Station that meets the quality specifications. The high contamination levels in the areas of previously mined workings and the deteriorating coal qualities in the southern portion of the mine, necessitates a coal processing plant. A coal processing plant will therefore be commissioned in 2023 and discard from the plant will be disposed of in-pit;

A temporary surface discard dump will be developed on a backfilled area to allow for the management of discard when spontaneous combustion or mine sequencing hampers in-pit discarding. This temporary surface discard dump is for 10 Mt discard disposal. This site will be equipped with pollution control facilities;

ROM stockpile in the plant area from where coal will be dispatched to the Kusile Power Station;

Emergency ROM stockpiles at Tip 1 and 2;

A number of pollution control facilities will be developed as part of the water management system. This includes the 36 Mℓ Plant Area Pollution Control Dam (PCD), the 15 Mℓ Admin Area PCD, the 1 200 Mℓ PCD and 100 Mℓ balancing dam at the WTP; as well as the eight pit ramp transfer dams and a PCD at Tip 2;

A 10 Mℓ bulk water supply storage dam will supply raw water for use as process water to the coal washing plant, washbays, dust suppression at the coal stockpile and for dust suppression on the haul roads;

The Final Void dam will be used for the storage of dirty water during extreme events.

v

Due to the rate of development in the field of water treatment, a decision has not been made regarding the technology that will be used in the permanent WTP. The waste streams associated with the WTP has therefore also not been identified. Although the generation of brine is expected to be unlikely, provision has been made for a brine disposal facility, in line with the precautionary approach, should it be required. The generation of a gypsum waste stream is expected and provision has been made for a gypsum handling facility, where gypsum will be temporarily stored and dried before it is removed. These facilities will be provided as part of the Phola-Kusile Overland Conveyor (or Stage 1 of the New Largo Colliery Project) when the mobile WTP will be commissioned. It has been included in the IWULA for the conveyor system.

Water for the operational phase will be sourced from the mobile WTP established as part of the Phola-Kusile Overland Conveyor (or Stage 1 of the New Largo Colliery Project). This WTP will initially have a treatment capacity of 4 Mℓ/day and will treat water pumped from the old underground workings. The capacity of the mobile WTP will be increased to 8 Mℓ/day by 2017 as part of the New Largo Colliery project and will be ramped-up to a final treatment capacity of 24 Mℓ/day.

Water will therefore be sourced from the underground workings initially during the de-watering stage, as well as from in-pit and on-site water make. Treated water from the WTP will be used as follows:

The portion of the treated water that will be used as potable water, therefore chlorinated, will be stored in a 1 Mℓ water reservoir from where water will be pumped to a 250 kℓ elevated water tank as described above;

Potable water from the WTP will also be used for dust and fire suppression along the conveyor systems;

Treated water, not chlorinated (i.e. not potable standards), will be used for wash-down water in the plant, conveyors and tips, as well as for dust suppression on the haul roads. The latter will be sourced from a bulk water storage dam, which will be supplied from a balancing dam at the WTP.

S21(j) Removing, discharging or disposing of water found underground if it is necessary for the efficient continuation of an activity or for the safety of people

During the construction phase, water will be pumped from the borrow pits developed at the box cut areas. These borrow pits need to be kept dry until coaling commences in 2015.

Dewatering of the underground workings of the old New Largo Colliery will take place to allow for continued mining. Initial dewatering is scheduled to commence in 2019, four (4) years prior to intersecting the underground workings by opencast mining activities. Following this initial dewatering period, continued dewatering from the underground workings will be required. The advancing opencast pit will also be dewatered to ensure the continuation of mining.

The New Largo Colliery will provide coal to the Kusile Power Station, which is of strategic importance in the current long-term power supply strategy for the country.

It will be an extensive opencast coal mine associated with impacts of a very high significance with regard to surface and groundwater that will require careful management and specialised long-term mitigation at considerable cost. In the opinion of the Environmental Assessment Practitioner, there is no alternative coal mine, or combination of smaller coal mines, that could supply the Kusile Power Station with coal on schedule and at the correct grade, quality and quantities – with less environmental impacts than those associated with the New Largo Colliery (Synergistics, 2012). It is therefore regarded as the best suited coal reserve to supply the Kusile Power Station and based on this, it is recommend that an integrated water use licence for mining Plan 6 be granted. It is requested that consideration be given to a phased approach in the issuing of the water use licence. The main reason for this request is that some of the water

uses, such as those associated with the construction phase are more urgent than others. The critical timeframes are indicated in the table below:

Definitions used in this report:

Clean water: Clean water is any water that has not been in contact with carbonaceous material or other potential contaminants and includes run-off from areas unaffected by mining activities, as well as areas that have been rehabilitated.

Dirty water: Dirty water is any water that has been in contact with carbonaceous material or other contaminants (i.e. water containing waste), and of which the water quality has been affected and therefore has the potential to cause pollution of a water resource.

Dirty water system: Any dam, or other form of impoundment, canal, works, pipeline, residue deposit and any other structure or facility constructed for the retention or conveyance of water containing waste (BPG A4).

Mine water: Mine water is water that accumulates in the underground workings or open pit and which may be of poor or good quality.

Groundwater Water that occurs in the voids of saturated rock and soil material beneath the ground surface is referred to as groundwater and the body within which the groundwater is found is referred to as an aquifer (DWAF, 2007).

Once groundwater enters the various pits and mining areas, it is considered to be dirty water.

Process water: Water that is used in the process of mining coal and includes plant water, water used for dust suppression and water used in slurry to allow the pumping of waste.

Product water: Permeate resulting from treatment at the water treatment plant.

Runoff: Surface runoff is water that finds its way into a surface water body without infiltration into the soil and may include overland flow, return flow, interflow and base flow (BPG G1).

Surface water: All water naturally open to the atmosphere (rivers, lakes, reservoirs, streams, impoundments, seas, estuaries, etc.); also refers to springs, wells, or other collectors that are directly influenced by surface water (DWAF, 2007).

Storm water: Water that accumulates on land as a result of precipitation events, and includes runoff from areas such as roads and roofs.

Watercourse: A river or spring; natural channel in which water flows regularly or intermittently; a wetland, lake or dam into which, or from which, water flows; and any collection of water which the Minister may, by notice in the Gazette, declare to be a watercourse, and a reference to a watercourse includes, where relevant, its bed and banks (NWA, 1998).

1. INTRODUCTION

1.1 Background

Anglo American Inyosi Coal (Pty) Ltd (hereafter AAIC) propose to develop a new opencast coal mine, the New Largo Colliery, to supply coal to Eskom’s new Kusile Power Station that is currently under construction between Bronkhorstspruit and eMalahleni in the Nkangala District Municipality of the Mpumalanga Province.

When fully operational, the Kusile Power Station will consist of six 800 megawatt (MW) units and hence will have a total capacity of 4 800 MW. At full production, the Kusile Power Station will require approximately 17 million tons (Mt) of coal per annum, depending on the quality of the coal. Anglo American Thermal Coal (AATC) has dedicated the New Largo coal resource to Eskom to supply the Kusile Power Station through its empowered subsidiary, AAIC, for a period of approximately 47 years commencing in 2013. A Memorandum of Understanding (MOU) with Eskom was signed in 2008. The intention is to source this coal from the New Largo Colliery, with supporting production from AAIC’s Zibulo No. 2 seam and Zondagsfontein No. 4 seam operations (AAIC, 2012b).

The New Largo coal reserve lies within AAIC’s current prospecting right area / proposed mining right area. The total mining right area is 12 773 hectares (ha), of which the opencast mining area (mine pits) will occupy an area of approximately 5 600 ha. The majority of the coal reserve lies between the N4 highway in the north and the N12 highway in the south, with a small portion found to the south of the N12 highway. The intention is not to mine through the N12 highway but to leave a buffer zone for the highway and other linear infrastructure running parallel thereto, such as the Transnet National Multi Product Pipeline. Both the No. 2 and No. 4 coal seams will be mined (Synergistics, 2011).

During the initial 2 years of operation, the Kusile Power Station will utilise coal that is transported via the proposed Phola Kusile Overland Conveyor from the Phola Coal Processing Plant. The Phola Kusile Overland Conveyor is a standalone entity to the New Largo Colliery and will be used to transport AAIC middling coal, as well as other third party coal to the power station. The Phola Kusile Overland Conveyor forms part of Stage 1 of AAIC’s coal supply to the Kusile Power Station. The water uses for this Stage of the project is addressed in a separate Integrated Water Use Licence Application (IWULA) (report number JW117/11/C184).

Report JW194/11/C184 - Rev 3

Integrated Water Use Licence Application Report

The New Largo Colliery represents Stages 2 and 3 of AAIC’s coal supply to the Kusile Power Station. Implementation is planned in two main phases:

Mining Phase 1 (Stage 2 of AAIC’s coal supply to the Kusile Power Station) entails general construction, the development of the first opencast box-cut in the northern section of the mining area and the commissioning of the first dragline. Construction will commence in the second quarter of 2013 and operations are expected to commence in the first quarter of 2015. A truck and shovel fleet will be in operation until 2023. This coal is of such a quality that it does not require beneficiation. The coal in this area will therefore be dispatched directly from the tertiary crushing plants to the Kusile Power Station;

Mining Phase 2 (Stage 3 of AAIC’s coal supply to the Kusile Power Station) construction will commence in the first quarter of 2020 and operations in the first quarter of 2023. This phase entails the development of opencast mining in the southern section of the mining area, commissioning of the second dragline in this section, as well as the commissioning of a coal processing plant. The water treatment plant (WTP) established during the initial phases, will also be expanded during this phase.

2. PROJECT DESCRIPTION

2.1 Project description

2.1.1 Project location

The New Largo coal resource is located in the Mpumalanga province, situated approximately 30 kilometres west of eMalahleni and 100 kilometres east of Johannesburg. The proposed colliery will be located in the eMalahleni and Victor Khanye Local Municipalities, which forms part of the Nkangala District Municipality. It is bounded by the N12 highway to the south and the N4 highway to the north, with a portion of the resource lying to the south of the N12 highway. The regional setting is indicated in Figure 2.1.1(a) and the locality map is provided in Figure 2.1.1(b).

Portions of the No. 2 and No. 4 Seams have been previously mined by underground methods to supply the now defunct Wilge Power Station (refer to Figure 2.1.1(c)). The largest and most extensive underground mine is the now defunct New Largo Coal Colliery. It is estimated that these defunct collieries extend over an area of approximately 1 300 ha and an estimated 45 million tonnes have been mined. Reserves are contained both in pillars and roof and/or floor of the workings.

2.1.2 Description of activity

Coal from the No. 2 and No. 4 seam will be mined at the proposed New Largo Colliery through opencast mining as indicated on Figure 2.1.2(a). The No. 4 coal seam is found between 8 to 47 m (20 m on average) below natural ground level and is on average 4.5 m thick. Coal seam No. 2 is located on average 13 m below seam No. 4 and varies in thickness between 4.6 to 8.2 m. Both coal seams can be mined in their entirety except in certain areas of the No. 2 seam where thick intra-seam partings will need to be mined out separately to enhance coal quality (AAIC, 2012b).

The Run of Mine (ROM) coal reserves are approximately 642 million tons and a yield of 85% is anticipated.

The opencast mining method was selected due to the low strip ratio, the ability to maximise the coal extraction and use of the coal resource, and to recover the coal reserves remaining in the areas that were previously mined by underground methods.

5



Draglines will be used for the removal of primary overburden due to the lower operating costs and the safer exposure of coal in previously mined underground areas. Two draglines will be utilised over the life of mine. Truck and shovel operations will, however, also be used to load and transport the coal in order to meet the coal supply requirements.

Large 190 ton payload trucks will be used for the hauling of coal to the two primary crushing plants.

Coal from certain areas within the New Largo coalfield is of such quality that it does not require beneficiation. This is directed straight from the primary crushing plant to the primary screening and tertiary crushing plant, and then onto the Kusile feed conveyor system.

Coal from areas where the contamination is higher, will be dispatched from the ROM stockpile to the primary and secondary screening plants and then into the coal processing plant and tertiary crusher. From here, it will be dispatched to the Kusile Power Station via the feed conveyor.

The R545 provincial tar road between Kendal and Balmoral provides a north-south link between the N4 highway to the north and the N12 highway to the south of the mining area. A section of this road (approximately 17 km) is located in the centre of the proposed mining area and therefore needs to be demolished to allow mining operations to proceed. The demolition and re-alignment of the road will be done during Phase 1. The proposed realignment is indicated in Figure 2.1.2(b). The water uses associated with the R545 re-alignment is addressed in a separate IWULA (refer to report number JW078/12/C184).

2.1.3 Extent of activity

The total AAIC prospecting right area / proposed mining right area is currently 12 773 ha. Approximately 5 600 ha will be mined by opencast mining.

2.1.4 Key processes and products

A number of mining methods were evaluated as part of the New Largo project. Opencast mining with draglines were selected as the most suitable method. In the early years of the mine (up to 2022), a truck and shovel fleet will also be used to ensure that the demand at the Kusile Power Station is met. This will be downscaled once the second dragline is commissioned in 2023.

Dragline cuts will on average be in excess of 3 km long and 60 m wide in single seam areas and 130 m wide in double seam areas. The proposed mining process is illustrated in Figure 2.1.4(a) and can be described as follows:

Vegetation and topsoil is stripped ahead of mining. At least one cut (60 m) should already be stripped and available for drilling between the active topsoil stripping operation and the open void;

In certain areas where significant clay subsoil will be encountered, it will be stripped separately and placed on levelled spoils and below the topsoil layer. This practice will reduce water seepage into the spoils due to the impermeable clay layer;

The topsoil and subsoil are loaded onto 100 ton trucks by hydraulic excavators and is hauled to the back of the advancing pit for live placement on top of the levelled spoils;

Overburden and interburden drilling operations commence in the front of the advancing pit after the topsoil has been removed;

Overburden/interburden (spoils) is drilled, charged with explosives and blasted;

After blasting the dragline and dozers move the spoils into the open void created previously in order to expose the coal seams at the bottom;

Once the coal is exposed, the drilling, blasting, loading and hauling of coal and intra seam partings commence;

The levelling of spoils will follow within three strips behind the open void;

Topsoil is placed on top of the levelled spoils, after which it is levelled, seeded and fertilized.

Coal of consistent quality should be supplied to the Kusile Power Station to ensure that the required combustion efficiencies are achieved. A coal processing plant will be required when mining proceeds to the southern areas where poorer quality coal is located. Higher quality coal (from the northern areas) will have to be blended with lower quality coal to ensure a constant supply at the correct specifications to Eskom.

14



A 132 kV power line with associated substations from Eskom will be constructed to supply New Largo Colliery. In addition, there will be smaller power lines and substations to supply power to the various operational areas within the New Largo mining right area; and

A number of fuel storage facilities located throughout the mining area. Each of the facilities will consist of bulk diesel and bulk lubricants, piped to various dispensing points. Access to the facilities for the bulk delivery vehicle is on internal roads outside the mining area. The required fuel storage capacity is 1 245 m3 during Operational Year 1 to Year 30, to be increased to 1 370 m3 for LOM (beyond Year 30). This is based on a 14 day stock holding capacity.

An existing 400 kV transmission line which runs from east to west across the resource area, numerous rural power lines and the R545 provincial road have to be relocated. This will be phased in with the mine plan over the life of the mine.

It should be noted that the list above depicts the full complement of infrastructure that will be developed over the life of mine, but that this will take place in phases as discussed in section 2.1.6. The required phasing and timing of water and waste management infrastructure is indicated in Table 2.1.5(a). Due to the phasing, final details of the infrastructure to be developed during Phase 2 may not available at this stage.

Water for the construction phase, will be obtained from three boreholes drilled into the old New Largo Colliery underground workings. These boreholes will be utilised during Stage 1 and abstraction will continue during further phases of the project.

Water for the operational phase will be sourced from the WTP, initially a mobile treatment plant that will be established as part of the Phola-Kusile Overland Conveyor. The WTP will initially treat water from the old New Largo underground workings. The mobile WTP will initially have a treatment capacity of 4 Mℓ/day. The capacity of the mobile WTP will be increased to 8 Mℓ/day by 2017 as part of the New Largo Colliery project and will be ramped-up to a final treatment capacity of 24 Mℓ/day. Water will therefore be sourced from the underground workings, as well as from in-pit and on-site water make.

2.1.6 Activity life description

Based on official communication that AAIC has received from Eskom, the first coal at the Kusile Power Station is required in the October 2013 in order to lay down stockpile beds and commission the coal stockyard equipment. The first unit is scheduled to start commercial operations in 2014 and the last unit is expected to come online in 2018 (Synergistics, 2012). During the initial stages, the coal demand will be supplied via the Phola-Kusile Overland Conveyor from other mining operations.

16



Terracing for dragline assembly will commence in September 2012 and the first dragline for the New Largo Colliery will be assembled from January 2013 to September 2015.

Construction and ramp-up of the New Largo Colliery will take place from 2013 to 2017, in two phases:

Mining Phase 1 (Stage 2 of AAIC’s coal supply to the Kusile Power Station) entails general construction, the development of the first opencast box-cut in the northern section of the mining area and the commissioning of the first dragline. Construction will commence in the second quarter of 2013 and operations are expected to commence in the first quarter of 2015. A small truck and shovel fleet will be in operation until 2023. This coal is of such a quality that it does not require beneficiation. The coal in this area will therefore be dispatched directly from the tertiary crushing plants to the Kusile Power Station;

Mining Phase 2 (Stage 3 of AAIC’s coal supply to the Kusile Power Station) construction will commence in the first quarter of 2020 and operations in the first quarter of 2023. This phase entails the development of opencast mining in the southern section of the mining area, commissioning of the second dragline in this section, as well as the commissioning of a coal processing plant. The water treatment plant (WTP) established during the initial phases of the New Largo Colliery Project, will also be expanded during this phase.

The life of mine of the New Largo Colliery is approximately 50 years and the mine will be at full production between 2017 and 2059.

Post closure, the overburden dump material will be used to backfill the final pits and voids. Infrastructure will be removed if it cannot be re-utilised for a suitable purpose in line with the final land use. The topography around the opencast area will be rehabilitated and made free draining. The proposed post mining topography is presented in Figure 2.1.6(a). The post mining topography will be undulating and the ramp scars will act as drainage paths area to convey any run-off from the rehabilitated area towards the Wilge River (located to the west of the mine) and Saalklapspruit (located to the east of the mine).

3. PRESENT ENVIRONMENTAL STATUS

3.1 Topography and drainage

The topography comprise of moderately flat to gently undulating plains. The proposed pit areas are located within the higher lying areas and the topography gently drops to the east and west along the watershed. The western side of the mining area drains into the Wilge River system, and the eastern side of the mining area drains into the Saalklapspruit system. Part of the northern section drains into the Saalboomspruit. Due to the generally flat topography, several isolated surface water pans are present.

3.2 Land use

Current land use includes sand and coal mining and agriculture (crop irrigation and livestock farming). Chicken farming and brickmaking activities are also practiced. Coal mining activities exist to the south of the proposed New Largo Colliery. The Voltargo Village and Phola Township are to the east.

It is estimated that approximately 20% of the coal reserve area comprises defunct collieries. The largest and most extensive is the now defunct underground New Largo Colliery where bord and pillar mining was undertaken until 1989. Approximately 1 150 ha was mined on the No. 4 Seam horizon and 280 ha on the No. 2 Seam. The depth of mining is 10 – 50 m below surface level. Water levels in the underground workings are controlled by pumping the excess water to a pan on the farm Klipfontein 566 JR. These workings have filled with water and are currently decanting at an average rate of 1 500 m3/day.

Extensive sand mining operations exist within the coal reserve area.

The Kusile Power Station is being constructed adjacent to the proposed mining area and the Phola-Kusile Overland Conveyor is planned between the Phola Washing Plant and the Kusile Power Station.

3.3 Climate

3.3.1 Temperature

The Eskom Kendal 2 monitoring station is located to the south of the proposed New Largo Colliery. The annual average maximum, minimum and mean temperatures for this station are given as 26°C, 10°C and 16°C respectively, based on the records for 2005 to 2009. The average daily maximum temperatures range from 30°C in December, January and February to 20°C in June, with daily minimum temperatures ranging from 15°C in January and December to 3°C in July (Synergistics, 2011).

3.3.2 Rainfall

The average monthly rainfall for Ogies South African Weather Station (SAWS) (station number 0478093) based on the period 1908 to 2000, is indicated in Table 3.3.2(a).

3.4 Geology and soils

3.4.1 Geology

The regional geology is described by Jasper Muller and Associates (JMA, 2011b) as follows:

The geology of the greater study is highly diverse and ranges from sedimentary lithologies of the Karroo Supergroup, through to intrusives of the Bushveld Igneous Complex. The surface geology consists predominantly of the sedimentary lithologies of the Ecca Group, denoted Pe or Pv on Figure 3.4(a). These lithological units consist of shale, shaly sandstone, grit, sandstone, conglomerate and coal, and cover the majority of the southern and south-eastern extent of the study area. The extents of the open cast mining operations at New Largo are confined to these sedimentary lithologies of the Ecca Group.

The Ecca Group form part of the Permian Age Karroo Supergroup, and have been extensively mined for coal within the Witbank Coal Fields of South Africa. The New Largo study area lies along the north-western extent of the Witbank Coal Fields.

The Ecca Group lithological units lie unconformably on top of the tillites of the late Carboniferous to early Permian Dwyka Group (Pd/C-Pd), which forms the base of the Karroo Supergroup. The dwyka tillites outcrop extensively at the surface to the east and west of the proposed pits at New Largo.

The surface geology to the north and far west of the study area is dominated by fine to medium-grained diabase (di) intrusives ranging in age from Vaalian to post-Mogolian. These diabases intruded into and above the Pretoria Group Sediments as well as the Wilgerivier Formation (Mw) of the Waterberg Group. The Mogolian Age sedimentary litholigical units of the Wilgerivier Formation consist predominantly of sandstones and conglomerates and outcrop extensively to the north of the study area.

23



Nebo granite (Mn) is indicated to occur to the north of the proposed New Largo mining activities as well. The Nebo granite forms part of the Raashoop Granophyre Suite of the Rustenburg Layered Suite of the Bushveld Complex and consists of coarse grained granites.

The surface geology across the northern and far western extent of the study area consists of sedimentary lithologies of the Pretoria Group. These include quartzites of the Magaliesberg Formation (Vm), shales of the Silverton Formation (Vsi), quartzites of the Dasspoort Formation (Vd) as well as quartzites and shales of the Strubenkop Formation (Vst). The Pretoria Group sediments are the oldest within the study area and have intermittently been intruded by diabase.

Based on the information obtained from the 1:250 000 Geological Map Series of South Africa sheets, there is no evidence of large scale faulting within the study area. No dykes are indicated on the sheets either and the extent of the intrusive lithologies is confined to that of the diabase as well as the intrusives of the Bushveld Igneous Complex.

The 1:250 000 Geological Map Series of South Africa sheets indicate that coal has historically and is currently still being mined within the extent of the study area.

3.4.2 Soils

Soil characteristics in the area are as follows:

Highly variable depth characteristics occur, with relatively small areas of rocky outcrop and ferricrete exposure (< 400 mm depth), and large areas of relatively deep (600 – 800 mm) to very deep (800 mm to > 1 500 mm) in situ derived soils that are often associated with cultivated lands and commercial livestock farming;

Generally moderate to low clay soils (10 – 25%) with low reserves of organic carbon (< 0.5%) and resultant high potential erodibility on the sedimentary derived (in situ) soils, to moderate clay (18 – 35%) contents, that are associated with better than average soil water holding characteristics (80 – 120 mm/m) and moderate land capability potential on the more basic soils and colluvial/alluvial derived materials (lower slopes);

Poor nutrient stores in association with high permeability rates in the upper soil horizons and poor water holding characteristics for the sedimentary derived soils and impermeable to low permeability on the soils associated with the hydromorphic soils and transition zone materials (ferricrete layer – “C” Horizon) that underlies the relic land forms and lower slope positions in many cases;

A ferricrete layer that forms a relatively impermeable barrier to sub surface water infiltration, forming sub-surface ephemeral pans and palaeo channels (sub-surface), a zone of sensitivity (restrictive barrier) that has ecological ramifications; and

Variations in the sensitivity of the soils to a change in utilization, their workability and reaction to being disturbed, and the relative ease of re-instatement when replaced on rehabilitation (Earth Science Solutions, 2011).

3.5.1 Water Management Area

The proposed New Largo Colliery is situated in the Wilge River catchment, which forms part of the Loskop Dam catchment of the Olifants River Water Management Area. It is situated on a watershed, with the western side of the mining area draining into the Wilge River and its tributaries, and the eastern side of the mining area draining into the Saalklapspruit and its tributaries (quaternary sub-catchments B20F and B20G respectively as indicated on Figure 3.5.1(a)). The Saalboomspruit (a tributary of the Saalklapspruit) joins the Saalklapspruit, which in turn joins the Wilge River, which drains into the Olifants River. The Olifants River flows to the Loskop dam and then through the central part of the Kruger National Park and into Mozambique. It eventually joins the Limpopo River and discharges to the Indian Ocean on the east African coastline.

3.5.2 Mean Annual Runoff

The Mean Annual Runoff (MAR) for various sub-catchments was computed using the WRSM2000 synthetic streamflow generation model. The results of the modelling are shown in Table 3.5.2(a) and the catchments and nodes are shown in Figure 3.5.2(a).

The 1:100 year floodlines are indicated in Figure 3.5.3(a). The methodology used to determine this is described in detail in report number JW120/11/C184 (J&W, 2012).

3.5.4 Resource Class, Receiving Water Quality Objectives and Reserve

Water quality objectives

The Directorate National Water Resource Planning (DNWRP) of the (then) Department of Water Affairs and Forestry (DWAF) developed a water quality management strategy for the Upper and Middle Olifants River catchment, which was published in 2009 (DNWRP, 2009). One of the key elements of this strategy was the development of Resource Water Quality Objectives (RWQO).

Interim RWQO were determined based on a current set of objectives in the Witbank, Klipspruit and Middelburg Dam catchments, which was modified to account for the water quality component of the Ecological Reserve. Where previous RWQO were not available, the South African Water Quality Guidelines together with the present water quality status were used to determine RWQO. The set of RWQO determined are interim objectives that will be reviewed once the water quality component of the Ecological Reserve has been updated (DNWRP, 2009).

The proposed development is located within Management Unit (MU) 20 and 21 for the Saalklapspruit, and MU 22 for the Wilge River catchment respectively, as indicated in Figure 3.5.4(a). The Interim RWQO developed by the DNWRP for these management units are indicated in Table 3.5.4(a).

Resource class

The establishment of resource classes for the Olifants River WMA is still in process.

In terms of the river component of the National Spatial Biodiversity Assessment, quaternary catchment B20F is considered to have rehabilitation potential, while B20G is considered transformed (EcoInfo, 2011). The Wilge River is classed as a third order river, and under natural conditions is considered a perennial river. The Saalklapspruit is classed as a first order river, and under natural conditions is considered a non-perennial river. The assigned river signature2 for the Wilge River is “Highveld”, which is an endangered signature and the Saalklapspruit has a critically endangered river type (EcoInfo, 2011).

2 Assigned river signature reflects the conservation significance of a drainage system as determined by the National

Spatial Biodiversity Assessment

3.5.5 Surface water quality

The baseline water quality assessment is described in detail in the surface water report (JW120/11/C184). Water quality sampling and analyses was done according to the Surface Water Monitoring Protocol developed for the project (J&W, 2010).

The current water quality in the Wilge River catchment has not been impacted to a large extent and generally is within the interim RWQO’s for MU22 as developed by the DNWRP. The only exception is the Klipfonteinspruit, where an impact associated with the decant of mine water from the old underground workings (refer to Figure 2.1.1(c)) has been observed. The impact is noticeable in the macro and micro constituents of the water in the Klipfonteinspruit. The high dissolved aluminium values observed at this point is of particular concern. The poor quality water in the Klipfonteinspruit is, however, diluted with good quality water from reaches further upstream, resulting in water quality further downstream which generally is in the order of the interim RWQO for MU22. The exception is aluminium which exceeded the objective on most occasions. It should be noted that the interim RWQO for aluminium is based on the Aquatic Ecological Reserve determined in 2001 (DNWRP, 2009). When the aluminium levels are compared to the SA Water Quality Guidelines for irrigation and stock watering, the measured quality is below the target guideline of 5 mg/ℓ. The levels at most of the monitoring points are above the ideal domestic guideline of 0.15 mg/ℓ, but below the acceptable guideline for domestic use of 0.5 mg/ℓ.

Historical data for the DWA gauge B2H014 (at Onverwacht on the Wilge River) show a steady deterioration in the water quality in the Wilge River downstream of the proposed conveyor system, the proposed New Largo Colliery and the Kusile Power Station. The levels of sulphate, chloride, calcium and magnesium are approaching the interim RWQO set for the MU. Any further contribution of salt load into the system can therefore not be tolerated.

The water quality in the Saalklapspruit catchment is of poorer quality and does not comply with the interim RWQO’s for MU21. The mining and industrial activities in the upper reaches of the Grootspruit, a tributary of the Saalklapspruit, seem to have a high negative impact on the water quality. The Phola Sewage treatment plant also contributes to the poor water quality observed in the Saalklapspruit. This could have implications for the downstream water users as the water may not be fit for its intended use.

The DNWRP indicated that the system does not have any salinity assimilative capacity left and that the salinity load will have to be removed from the catchment in order to meet the RWQO’s for the Loskop Dam. This will involve the management of pollution sources such as decants and seepages from defunct mines. In future, mines will have to treat water to acceptable levels (DNWRP, 2009).

3.5.6 Surface water use

A survey was done of the current surface water use within the area as part of the surface water specialist study. This was done through a questionnaire in which information was requested regarding the source of water use, the purpose (e.g. crop irrigation or livestock watering) and an estimate of the extent of the use (e.g. area irrigated or number of livestock units). Details of the outcome of this study are not provided here and can be referenced in the surface water specialist report.

Surface water in the study area is used primarily for agricultural irrigation and livestock watering purposes. Approximately 1 000 ha of maize, wheat, soya and planted pastures is irrigated from surface water resources, mainly through centre pivot irrigation. On a smaller scale, crops such as potatoes, peanuts and cabbage are

33



irrigated from surface water resources using spray irrigation methods. Other commercial activities include chicken farming and brick making facility.

Domestic water use is mainly from groundwater resources. Rivers and dams are used for recreational activities such as swimming, fishing and canoeing (where water quality permits such activities).

Several mines (coal and sand mines) also make use of the surface water resources in the area.

Downstream water users include agricultural irrigation (Gouwsberg Irrigation Board area and the Loskop Dam Irrigation Board further downstream), as well as game farming.

3.5.7 Wetlands

A detailed wetland assessment was undertaken by Wetland Consulting Services (WCS) as part of the EIA.

The types of wetlands and area occupied are indicated in Table 3.5.7(a). Wetlands occupies a total of 1 600 ha represent 14% of the total study area of approximately 11 470 ha as defined by WCS. The distribution of wetlands is indicated in Figure 3.5.7(a).

Table 3.5.7(a): Types and area of wetlands (WCS, 2011)

Wetland type Area (ha) Percentage (%)

Valley bottom wetlands 413 26

Hillslope seepage wetlands 978 61

Pans 164 10

Dams 45 3

TOTAL 1 600 100

The proposed mining area straddles a catchment divide with flows to the east feeding the Saalklapspruit and those to the west the Wilge River. Three large and three small pans are located on the crest of this drainage divide. The flows off the “ridge”’ emerge as seepage wetlands where the aquiclude intercepts the side slopes and where flows concentrate in the valley bottoms.

The valley bottom wetlands on the tributaries of the Saalklapspruit are largely channelled, indicating that the energy associated with the flows is high enough to result in sediment transport. The large Phragmites stands in the Saalklapspruit are a reflection of the deposition of sediments emerging from the upstream catchment. The valley bottom wetlands associated with the tributaries of the Wilge River are largely un-channelled within the study area. Some evidence of channel development was observed in the systems on the farm Klipfontein. The absence of any extensive reed beds in the Wilge River suggest that the energy associated with flows out of this section of the catchment is high, thus transporting sediments to beyond the study area. The relatively large surface area representing seeps suggests that a considerable portion of the rainfall falling in this area enters the valley bottom systems as diffuse flow, over an extended period (WCS, 2011).

None of the wetlands in the area is regarded as pristine due to the agricultural and mining activities, as well as infrastructure development (roads and railways) that have taken place. Wetlands in the north eastern section are the least impacted. Cultivation

34



has mainly taken place outside of the boundaries of the valley bottom wetlands, and as such there has been little direct effect of cultivation on these wetland systems. The hillslope seepage wetlands have however been heavily impacted by agriculture and the smaller pans have similarly been impacted by cropping. In addition, return flows from the centre pivot irrigation systems are also likely to have affected the wetlands (WCS, 2011).

All the pans have hillslope seepage wetlands on the slopes of the pan basins, indicating the flow of water from the surrounding catchment into the pans. The pan on the Farm Klipfontein (east of the R545) is used for the discharge of mine water from the underground workings of the defunct New Largo Colliery. In addition, the pan also receives what appears to a low pH, sulphate rich decant in the vicinity of the old mine located immediately south of the pan. The remaining pans on the site have been affected by sand mining operations, as well as cultivation around the perimeters.

An assessment was done of the Present Ecological State (PES) of the wetlands. The results are summarised in Table 3.5.7(b) as a percentage of the area of each wetland type. The majority of the wetlands fall in Category C and D, implying that a large change in the ecosystems has occurred, but in the case of those in category C, the functioning of the system has not been severely compromised. The distribution of the wetlands in the classed identified is presented in Figure 3.5.7(b).

C (Moderately modified) 71.1 30.3 40.4

The Ecological Importance and Sensitivity (EIS) of the wetlands is summarised in Table 3.5.7(c) and indicated in Figure 3.5.7(c). Some discrepancies were observed between the PES and EIS assessments. This apparent contradiction can be explained as follows:

where water quality has been impacted, wetlands assume a more important role since they support processes that improve water quality;

as more and more wetlands are transformed or lost, the remaining wetlands take on a greater significance from both a biodiversity perspective, and what they reflect in terms of landscape hydrological processes (WCS, 2011).

3.5.8 Aquatic ecosystem

A detailed aquatic assessment was undertaken by EcoInfo as part of the EIA. The following standard bio-monitoring protocols were used to determine the PES of the rivers:

Invertebrate Habitat Assessment System (IHAS);

Index of Habitat Integrity (IHI);

Aquatic Macro invertebrates using South African Scoring System 5 (SASS5);

Fish using the Fish Response Assessment Index (FRAI); and

Diatom Assessment.

A description of the PES categories is provided in Table 3.5.8(a) and the outcome of the assessment is provided in Table 3.5.8(b). The position of the monitoring points is indicated on Figure 3.5.8(a).

The response metrics assessed indicated that the ecological integrity of the system is under threat due to current land use activities impacting on the general river system.

The observed present state of the river and habitat supports 10 confirmed species of fish from four families, and could potentially support another four species that occur in the general aquatic ecosystem. Of the species sampled, one can be considered highly sensitive to changes in water quality, namely Chiloglanis pretoriae. This is a rheophillic3 fish species that is highly sensitive to alterations in preferred habitat.

The Wilge River signature is Bushveld Basin 2 and the Saalboomspruit River signature is Highveld 1, which is respectively considered Critically Endangered and Endangered according the National Spatial Biodiversity Assessment. These systems are already under severe threat and pressure due to farming activities, as well as urban and mining development (EcoInfo, 2011).

3.6 Groundwater

3.6.1 Regional geohydrology

The regional geohydrological attributes of the study area are a function of the geological host matrix distribution. The central extent of the study area is underlain by arenaceous sedimentary lithologies of the Ecca Group. The geology of the north-western and south-eastern extents of the study area is predominantly underlain by tillites of the Dwyka Group. The surface geology to the north and east of Pit A consists predominantly of lithologies of the Pretoria Group.

The groundwater within the study area primarily occurs within the weathered zone or in joints and fractures of the competent arenaceous rocks, related to tensional or compressional stresses and offloading. Groundwater also occurs along sedimentary – sedimentary or sedimentary – igneous rock contacts. Localised large water bearing fractures generally occur along the sedimentary – igneous contact zones related to the heating and cooling of the arenaceous host rock caused by the intrusion of dolerite dykes and sills as well.

The average expected borehole yield within the central parts of the study area (Ecca Group) is between 0.1 and 0.5 ℓ/s. For the northern, north-eastern, far eastern and far western extents of the study area an average yield of between 0.5 ℓ/s and 2.0 ℓ/s is expected. No large scale groundwater abstraction is indicated to occur from these intergranular and fractured aquifers within the bounds of the study area. The groundwater potential within the study area is given as being between 40% and 60%, and indicates the probability of drilling a successful borehole (yield > 0.1 ℓ/s). The probability of drilling a borehole with a yield in excess of 2 ℓ/s is however given as between 10% and 20%.

The mean annual recharge to the groundwater system in the study area is estimated to be between 50 mm and 75 mm per annum, which relates to between 6.5 and 10% of the mean annual precipitation (MAP). The groundwater contribution to ground stream base flow is estimated to be between 10 and 25 mm per annum.

The aquifer storativity (S) for the intergranular and fractured aquifers in the study area is inferred to be between 0.01 and 0.001. The saturated interstice types (storage medium) are pores in disintegrated / weathered to partly weathered and fractured rocks, as well as fractures which are restricted principally to the zone directly below the groundwater level (JMA, 2011).

3.6.2 Aquifer characterisation

Two dominant aquifer types occur at New Largo:

a laterally extensive shallow weathered zone aquifer, and

more localized fractured aquifer systems.

The predominant aquifer type present within the study area is the laterally extensive shallow weathered zone aquifer which occurs within the weathered and weathering related fractured zone, within the Ecca Group, Dwyka Group and Pretoria Group host rock matrices. This aquifer extends across the entire extent of the study area and has an average vertical thickness of 20.77 m. This aquifer zone will store and transport the bulk of the groundwater in the study area, and will display unconfined to semi-unconfined piezometric conditions. Due to the unconfined nature of the aquifer zone, it is as a result, highly susceptible to surface induced activities and impacts.

43



The localized fractured aquifers present within the study area are restricted to the contact zones between the intrusive diabase bodies and the host rock. Although these semi-confined fractured aquifers may be high yielding, they will have limited storage capacities and recharge characteristics. The bulk of the water supplied by these aquifers will be drained laterally from storage within the shallow weathered zone aquifers neighbouring onto them.

Isolated perched aquifer conditions were observed to the north-east of the proposed mining area at New Largo, beyond the extent of the delineated pit boundaries. These isolated perched aquifers are responsible for the hill slope seepages observed on the surface, but could not be accurately delineated. It is however known that they are not laterally extensive but rather form discontinuous isolated lenses which are dependent on the underlying soil profiles.

The major aquifer zones present within the New Largo study area consist of unconfined to semi-unconfined unsaturated and saturated zones:

Unsaturated Zone:

Due to the nature of the shallow weathered zone aquifer at New Largo, the top of the unsaturated zone is defined by the land surface, whilst the bottom of the unsaturated zone is defined by the groundwater table/level. The thickness of the unsaturated zone is therefore defined as the depth to the groundwater level.

The thickness of the unsaturated zone was calculated using the water level data recorded in the geohydrological investigative boreholes as well as in the boreholes identified during the groundwater hydrocensus conducted on the farms adjacent to the proposed pit extents. The thickness of the unsaturated zone (depth to the water level) varies between 0.10 m and 50 m at which the groundwater level has been affected by groundwater abstraction. The natural groundwater level depths recorded at the geohydrological investigative boreholes indicate that the natural unsaturated zone thickness varies between 2.14 m and 19.86 m with an average thickness of 8.78 m within the study area.

Saturated Zone:

The saturated zone of the shallow weathered zone aquifer at New Largo is defined at the top by the groundwater table/level and at the bottom by the weathered/fractured and fresh bedrock interface. The natural saturated aquifer zone thickness of the shallow weathered zone aquifer at New Largo is thus calculated by subtracting the measured groundwater level depth from the weathered or weathering related fractured depth as recorded at the geohydrological investigative boreholes. The thickness of the saturated zone varies between 0.00 m, at which the water level is within the fresh host rock matrix, and 27.99 m. The average saturated zone thickness within the shallow weathered zone aquifer at New Largo is 11.45 m.

Further aquifer characteristics are as follows:

The blow yields recorded from 17 geohydrological investigative boreholes vary between 0.01 ℓ/s and 3.33 ℓ/s with an average yield of 0.23 ℓ/s;

The arithmetic mean permeability of 15 geohydrological investigative boreholes was 0.76 m/day;

The calculated average aquifer transmissivities of 15 geohydrological investigative boreholes was 5.06 m2/day;

44



The storativity (S) of an aquifer is defined as the volume of water that an aquifer releases from, or takes into, storage per unit surface area of the aquifer per unit hydraulic gradient. The average storativity of the shallow weathered zone aquifer at New Largo is taken as 0.002; and

The effective porosity in the weathered zone aquifers at New Largo will vary between 0.01 and 0.07, with a bulk probable effective porosity value of 0.05.

3.6.3 Aquifer dynamics

Recharge to the shallow weathered zone aquifers at New Largo will occur annually as a function of rainfall and infiltration. The mean annual recharge to the groundwater system for the study area is estimated to be between 3% and 7% of the MAP, putting it in the recharge range of 25 mm/annum to 55 mm/annum (taking the MAP as 736 mm/annum).

The depth to the natural groundwater level at New Largo varies between 2.14 m and 19.86 m with an average depth of 8.78 m within the study area.

The groundwater elevation within the study area ranges between 1513.30 mamsl and 1579.38 mamsl.

Groundwater generally flows from the topographical higher areas towards surface water features in the area.

3.6.4 Hydrocensus

The use of groundwater within the study area was assessed using the information obtained from the various hydrocensus’ conducted within the study area between 2004 and 2011. A total of 309 groundwater receptors were identified. Of the 309 sites identified during the hydrocensus’, 46 are fountains and 263 are boreholes or wells.

During the hydrocensus conducted in 2011 it was observed that around 270 people use groundwater that abstracted from within study area for domestic use. The groundwater abstracted from within the study area is used as a water supply for around 1250 large livestock, around 600 small livestock and for 2 dairy operations. Abstracted groundwater is also used in gardens, in a brick factory, for sand washing as well as the washing of coal.

Groundwater that emanates at the surface (fountains) is predominantly used as a water supply for around 1100 large livestock and 760 small livestock. Around 25 people use the water obtained from the fountains for domestic use and one fountain is identified as a water supply for a garden as well. The water obtained from several fountains is also used for sand-washing and as a water supply for dairy cattle as well.

Important to note is that 12 boreholes/wells and 5 fountains that were identified during the 2004 hydrocensus have since been destroyed as a result of dumping that has taken place to the west of the study area.

3.6.5 Groundwater quality

The groundwater quality is discussed in detail in the geohydrological report by JMA (JMA, 2011)

The groundwater quality at New Largo was observed to be fully compliant with regards to the SANS 241:2006 Drinking Water Standard. The groundwater sampled at 28 geohydrological investigative boreholes has a quality that falls within the quality range of the background groundwater quality.

45



1.1.1 Aquifer classification

The aquifer is rated as a Minor aquifer system in terms of the Aquifer System Management Classification with a high vulnerability in terms of the Vulnerability Classification. These ratings yield a Ground Water Quality Management Index of 6 for the shallow weathered zone aquifers, indicating that medium level ground water protection is required. (i.e. the pollution control dams and other waste and water management facilities need to be sufficiently lined to protect the ground water resource).

4. WATER USES

4.1 Water uses associated with the project

The water uses requiring authorisation for Phases 1 and 2 of the New Largo Colliery are summarised in Table 4.1(a). For ease of reference, each water use has been allocated a reference code that is reflected on a drawing that is referenced in the Table and attached in Appendix A. The water uses are described below and detailed information on the water uses are provided in water use tables in Appendix A.

It should be noted that not all the details of the Phase 2 water uses are available at this stage and any changes will be addressed in an application for an amendment of the water use license, if required.

4.1.1 S21(a) Taking water from a water resource

Abstraction of groundwater for construction purposes will be required during the construction phase. According to GN R399 dated March 2004 (as extended in GN 837 dated 23 September 2010) quaternary catchment B20F and B20G fall within Zone C. In this Zone, 75m3 of groundwater may be abstracted per hectare per property per annum. Boreholes BH2 and BH3 are located on Portion 1 of the farm Klipfontein 566 JR (± 379 ha), and BH1 is located on Portion 4 of the farm Klipfontein 566 JR (±159 ha). Therefore, 28 425 m3/a and 11 925 m3/a may be abstracted from these properties respectively (a total of 40 350 m3/a). These water uses were included in the IWULA for the Phola-Kusile Overland Conveyor, and once authorised it will continue in terms of that license.

During the construction phase (in June 2013), borrow pits will be developed at the box cut areas. The purpose will be for the removal of material for construction purposes and coal will not be exposed until mining commences in 2015. These borrow pits will be kept dry by pumping water from the borrow pits to a settling dam until coaling commences (also refer to S21(f), (g) and (j) water uses).

Water will be pumped from the old underground working and the advancing pit to ensure that mining activities continue (refer to S21(j) below). The water will be treated in a mobile treatment plant that will be established as part of the Phola-Kusile Overland Conveyor (or Stage 1 of the New Largo Colliery Project). The mobile WTP will initially have a treatment capacity of 4 Mℓ/day and will treat water pumped from the old underground workings. The capacity of the mobile WTP will be increased to 8 Mℓ/day by 2017 as part of the New Largo Colliery project and will be ramped-up to a final treatment capacity of 24 Mℓ/day. Water will therefore be sourced from the underground workings in the initial stages, as well as from in-pit and on-site water make to supply in the demand during the operational phase.

46



4.1.2 S21(b) Storing water

Treated water will be pumped to a 1 Mℓ potable water reservoir located at the WTP. From this reservoir, water will be pumped to a 250 kℓ elevated potable water tank provided as part of the Phola-Kusile Overland Conveyor. Water for Phases 1 and 2 of the New Largo Colliery will be provided from this elevated tank. Potable water will gravitated to the reticulation system that supplies the buildings, workshops, offices, Tips 1 and 2 and the explosives magazine.

Potable water is required for dust suppression at the conveyor transfer points, as well as for dust suppression at Tips 1 and 2. This will be sourced from the elevated water tanks and stored in tanks at the transfers and Tips.

An additional 1 Mℓ storage tank will be established close to the abovementioned reservoir during Phase 2 when the coal processing plant is developed.

Fire water will be sourced from two fire water tanks (420 kℓ each) next to the potable water reservoir. This will also be provided as part of the Phola-Kusile Overland Conveyor (or Stage 1 of the New Largo Colliery Project) and was addressed in the IWULA for that stage of the project (refer to report number JW117/11/C184).

4.1.3 S21(c) Impeding or diverting the flow of water in a watercourse and/or S21(i) altering the bed, banks, course or characteristics of a watercourse

A number of wetlands and other watercourses are present in the proposed mining area. These watercourses will be mined partially or completely as indicated on Drawing C184-04-002 in Appendix A. Co-ordinates for the affected watercourses are provided on Drawing C184-04-008.

A number of watercourses will also be altered due to the development of infrastructure in the vicinity, or within, the watercourses (as indicated on Drawing C184-04-002):

The haul road on the mine will cross a number of watercourses. Where the haul road crosses watercourses, box or pipe culverts will be provided that are designed to accommodate at least a 1:50 year rainfall event. Flood protection in the form of gabion mattresses and stone pitching will be provided at the inlet and outlet of the culvert crossings. Drainage facilities for polluted water run-off from the haul roads include concrete lined drains, junction boxes, culverts and sumps. These have been designed to accommodate a 1:50 year storm. The drains report to the closest pit water transfer dam or other dirty water management system (AAIC, 2012c) ;

One borrow pit will be established within a seepage wetland;

Two borrow pits will be developed on the edge of a pan and a valley bottom wetland respectively.

The current alignment of the 132 kV power line crosses or encroach a number of wetlands (refer to Figure 2.1.2(a), as well as Drawing C184-04-002 attached in Appendix A). Although the detailed design of this line still needs to be concluded, AAIC has committed to ensure that no structures associated with the line are located within wetlands or 500 m from wetlands. It is therefore assumed that there are therefore no S21(c)&(i) water uses associated with this infrastructure. Should this not be feasible and any water uses are identified at a later stage, a relevant application will be submitted to the Department.

47



4.1.4 S21(f) Discharging waste or water containing waste into a water resource through a pipe, canal, sewer, sea outfall or other conduit

Discharge from the settling dam at borrow pits at box cut areas

Water (seepage and rain water) from the borrow pits developed at the box cut areas will be pumped to settling dams / silt traps. Any suspended solids will be allowed to settle, where after it will be discharged into existing farm dams.

Discharge from WTP

Treated water that is not used towards the water demand of the mine, will be discharged to the receiving watercourses.

A preliminary assessment was done of the discharge points, based on surface water run-off considerations only and assuming proportional discharge amongst the affected streams (J&W, 2011), attached as Appendix B. During this assessment, the proportional loss of catchment was determined at key stages in the life of mine. The proportional flow reduction was based entirely on the affected catchment areas (i.e. the assumption that the flow reduction will be directly proportional to the catchment area lost as a result of mining and mining related activities). A total of 16 discharge points (NLD1 – NLD16) were identified on this basis.

Not all discharge points will therefore be used from the start. Initially, only discharge points NLD1, NLD12 and NLD13 (refer to Drawing number C184-04-009 attached in Appendix A) will be used since mining will commence in the north east of the mining rights area. As mining progresses to the east and south, additional discharge points will become operational.

The final discharge volume and positions are, however, subject to the outcome of the Reserve Determination that is being conducted by WCS. The expected date of completion is May 2013 and in light of the timeframes of the project and the issuing of the water use license, the preliminary discharge points are included in the IWWMP and IWULA.

The Reserve Determination study will consider the Ecological Water Requirement (EWR) at key sites along the streams, close to the outlet of each of the preliminary identified Resource Units (RU’s), and will not provide details for each affected stream as discussed in the preliminary discharge assessment by J&W. The approach will therefore more likely focus on the combined discharge flows that will affect a particular EWR site downstream.

WCS has indicated that the distribution of discharge volume amongst the preliminary positions referred to above make sense from a mitigation perspective and the current understanding of the potential impacts on the water resources. The proposed approach is likely to reduce the flow volumes into each of the affected systems, thereby reducing the risks of erosion at any particular site. Furthermore, it serves as an attempt to restore some flow in those systems impacted by mining and dewatering in their watersheds. It may also have the added benefit of buffering water quality impacts across a wider front along the Wilge River and Saalklapspruit (reference: e-mail communication dated 30 May 2012).

The impact of the additional discharge on flood flows within the receiving catchments was assessed in the surface water specialist report (JW120/11/C184). The expected discharge equates at maximum to 1% of the 1:2 year flood event. Due to the small flows associated with the discharge, erosion is not expected to be a concern but should be monitored to ensure that appropriate action is taken should it occur.

48



Should the outcome of the Reserve Determination study result in changes to the preliminary list of discharge points, such changes will be addressed in an application for a water use licence amendment.

Discharge from 1 200 Mℓ PCD

Due to the significant storage required during extreme events in excess of the legislated current design parameters, AAIC intend to discharge water (that complies with an acceptable and authorised quality standard) from predetermined compartments of the 1 200 Mℓ PCD to the receiving environment (at discharge point NLD12). This will not be a continuous discharge and no discharge volumes can be provided or predicted. Discharge will only be done if the water complies with the Interim RWQO for the Wilge River catchment (refer to MU 22 in Table 3.5.4(a)), or the water quality specified in the Reserve determination.

4.1.5 S21(g) Disposing of waste in a manner which may detrimentally impact on a water resource

Settling dams at borrow pits developed at box cut areas

Settling dams / silt traps will be developed at the borrow pits developed at the box cut areas. Water removed from the borrow pits will be pumped to the settling dams / silt traps to allow any suspended solids to settle out before the water will be discharged into existing farm dams.. Coal will not be exposed and therefore the risk is limited to increased suspended solids.

Overburden stockpile

Topsoil and spoils (overburden and interburden) from the initial box-cut will be placed on an overburden stockpile to the north west of the mining operation. Thereafter, live placement of the overburden and topsoil will take place and each consecutive strip will be dealt with in a continuous roll-over mining method.

It was recommended by the geohydrologial specialist that placement should be in the sequence of hard overburden at the bottom of the spoils, covered by soft overburden and then topsoil. The reason for this layering is to mimic the natural soil and lithological profile as far as possible. In order to do this effectively, the topsoil, soft overburden and hard overburden should be individually and separately stripped ahead of the advancing box-but, to minimize the mixing of the material (JMA, 2011b).

At the end of the life of the mine, the stockpiled material removed from the initial box-cut will be used in the rehabilitation of the final mining areas.

Discard disposal

During the initial years (mining Phase 1), coal from the northern pit will be dispatched directly from the crushing plants to the Kusile Power Station and therefore no discard will be generated. Waste rock will be disposed of in pit.

From 2023 when Dragline 2 will be commissioned and mining operations move to poorer quality coal in the southern pit, a coal processing plant will be commissioned. The overall yield per saleable tonne after the processing plant is commissioned is estimated to be in the region of 85%. This implies that 15% of the raw material feed to the processing plant will be removed as coal discard. The total estimated discards generated over the life of mine will be approximately 94 million tons. Following a conservative approach, disposal facilities for 100 million tons is being planned.

49



Discard from the coal processing plant will be disposed of in-pit in three compartments as indicated in Figure 4.1.5(a). Discard will be spread evenly on the No. 2 Seam floor. Details for each compartment are provided in Table 4.1.5(a).

Table 4.1.5(a): Details of in-pit discard disposal

Compartment number

Location Period in use Amount of

discard Depth of discard

Compartment 1 North pit 2023 – 2039 6.3 million tons 0.45 m

Compartment 2 Central pit 2023 – 2063 82.7 million tons 2.2 m

Compartment 3 South pit 2043 – 2058 4.8 million tons 0.5 m

In addition, a temporary surface discard dump will be developed on backfilled open cast workings. This facility will be used during circumstances when in-pit discard disposal is not possible. It will be located in the southern portion of the northern mining area as indicated on Drawing C184-04-005 attached in Appendix A. The material will eventually be backfilled into the pit.

Provision has been made for an area of 700 m x 700 m which will provide for 10 Mt temporary storage during the life of mine. In situ ground preparation is envisaged (impact roller or similar) or alternatively discard will be dumped and pushed out progressively (approximately 1 m thick) before the provision of compacted layers. The discard dump will have side slopes of 1:8, and progressive rehabilitation will be done. Provision will be made for clean water diversion (ref: summary received from Duncan Cameron, as updated by Cindy Smith). The design of the discard dump and associated PCD is indicated on Drawings number 0000-0130-CED-0202 and 0000-0130-CED-0203 by Semane attached in Appendix E of the IWWMP.

ROM stockpile and emergency ROM stockpiles

Although not a waste steam, the stockpiling of coal could potentially impact on the water resource and therefore appropriate protection should be provided.

A ROM stockpile will be located in the plant area as indicated on Drawing C184-04-005 in Appendix A. Coal will be dispatched from the stockpile to the Kusile Power Station.

The areas where coal will be stockpiled will be prepared as follows (from bottom to top):

Rip in situ material and re-compact to 93 % MOD AASHTO;

A 150mm layer of G7 material compacted to 95% MOD AASHTO;

GCL layer (Envirofix X100 or similar);

2 x 150 mm layer of G7 material compacted to 95% MOD AASHTO.

The lay-out and designs for the ROM stockpile area is indicated on Drawings number 0000-130-CED-0160 to 0000-130-CED-0163 by Semane, attached in Appendix E of the IWWMP.

50



Figure 4.1.5(a): In-pit discard disposal areas

51



An Emergency ROM stockpile will be located at each of the two Tips. The base of these facilities will be prepared by rip and re-compaction of the in situ material, followed by the provision of a 150mm bentonite augmented layer and a 150mm layer of G7 material compacted to 95% MOD AASHTO. Clean storm water diversion berms will be placed on the upstream sides and dirty water collection drains will be constructed from concrete to collect any seepage from the facilities. Dirty water will be conveyed to the closest PCD. Details of these facilities are indicated on Drawings number 0000-0130-CED-0127 and 0000-0130-CED-0128 by Semane, attached in Appendix E of the IWWMP.

Dirty water storage

A number of pollution control facilities will be developed as part of the water management system. This includes the 36 Mℓ Plant Area PCD, the 15 Mℓ Admin Area PCD, the 1 200 Mℓ PCD and 100 Mℓ balancing dam at the WTP; the 10 Mℓ bulk water supply storage dam, the PCD at Tip 2, the PCD at the surface discard dump, as well as eight pit ramp transfer dams.

Admin Area and Plant Area PCD’s

Contaminated run-off from the Admin Area and DMS plant will be collected in the Admin Area PCD and Plant Area PCD respectively. These dams will have a capacity of 15 Mℓ and 36 Mℓ respectively and will be lined with 2 mm HDPE. The details of the Admin Area PCD are indicated on Drawings number 000-0130-CED-0192 and 000-0130-CED-0193 and for the Plant Area PCD on Drawings number 000-0130-CED-0190 and 000-0130-CED-0191 by Semane (attached in Appendix E of the IWWMP).

The Plant Area PCD will also receive effluent from the sewage treatment plant.

These dams will each be equipped with a silt trap and will be designed to accommodate at least a 1:50 year flood event. Water from these dams will be pumped to the 100 Mℓ balancing dam.

Polluted water dam at Tip 2

Dirty water run-off at Tip 2 will be collected in a lined 10 Mℓ PCD indicated on Drawing 0000-0130-CED-0229 by Semane. This dam will be lined with 2 mm HDPE (similar to the Plant Area PCD as indicated on Drawing number 000-0130-CED-0190) and will be equipped with a silt trap.

Pit ramp transfer dams

Water make from the pits will be pumped into eight pit ramp transfer dams situated at the haul road ramps. These will each have a capacity of 5 Mℓ and will be lined with 2 mm HDPE (similar to the Plant Area PCD as indicated on Drawing number 000-0130-CED-0190) and will be equipped with a silt trap. Details of these dams are provided in Drawings number 0000-0130-CED-0232 to 0000-0130-CED-0236 for the five pit ramp transfer dams that will be constructed during Phase 1 (refer to Appendix E of the IWWMP).

From the storage dams, water will be pumped to stilling chambers via buried pipelines. Water will flow from the stilling chambers into a double silt trap upstream of the 100 Mℓ balancing dam situated at the WTP.

10 Mℓ bulk water storage dam

Water to be used for dust suppression on the haul roads will be stored in the 10 Mℓ bulk water supply storage dam which will be sourced from the 100 Mℓ balancing dam. This dam will be lined with 2 mm HDPE as indicated on Drawings number 0000-0130-CED-0278 and 0000-0130-CED-0279.

52



PCD at surface discard dump

The surface discard dump to be constructed on a backfilled area will be equipped with a 5 Mℓ PCD indicated on Drawing 0000-0130-CED-0203 by Semane. This dam will be lined with 2 mm HDPE (similar to the Plant Area PCD as indicated on Drawing number 000-0130-CED-0190) and will be equipped with a silt trap.

1 200 Mℓ dewatering reservoir and 100 Mℓ balancing dam

The 1 200 Mℓ dewatering reservoir and 100 Mℓ balancing dam will together comprise the central dirty water storage and will be located adjacent to the WTP. These dams will be the main supply to the WTP. The 1 200 Mℓ dewatering reservoir will consist of five compartments, each with differing capacity (refer to Drawings number 0000-0130-CED-0230 and 0000-0130-CED-0231 attached in Appendix E). It will be lined with 2 mm HDPE (similar to the Plant Area PCD as indicated on Drawings number 000-0130-CED-0190) and will be equipped with a silt trap and all inlet and outlet structures will consist of reinforced concrete.

Inflows into the 1 200 Mℓ dam are as follows (refer to the water flow diagram attached in Appendix E of the IWWMP).

Dirty water from the Admin Area PCD;

Dirty water from the Plant Area PCD;

Dirty water from the eight Pit Water Transfer Dams;

Dirty run-off from the ROM stockpiles and emergency ROM stockpiles;

Dirty run-off from the Tip 1 and Tip 2 areas;

Dirty water from the PCD at the discard dump; and

Mine water from the old underground workings.

Final void dam

The 1 200 Mℓ dam will be able to accommodate the 1:50 year event up to 2018 and the 1:100 and 1:250 year events up to 2017. Thereafter additional storage will be required for extreme events. Currently the preferred option is an in-pit dam (Final Void Dam) located in Pit G, in the north western corner of the mine. The dam has an estimated a capacity of 1 000 Mℓ and will become available in 2022. The dam basin will be shaped and lined with 2 mm HDPE (refer to Drawing number 000-0130-CED-0274 in Appendix E of the IWWMP).

Waste facilities at WTP

A brine pond and gypsum handling area will be constructed as part of the Phola-Kusile Overland Conveyor (or Stage 1 of the New Largo Colliery Project) for the mobile water treatment plant associated with that development. The location of these will be at the area earmarked for the permanent WTP of the New Largo Colliery. These facilities are addressed in a separate IWULA and IWWMP (JW117/11/C184 and C118/11/C184 respectively) and will therefore be authorised in terms of these applications. The facilities will, however, be used (and expanded as may be required) for the disposal of waste from further phases of the WTP at the New Largo Colliery. The waste streams generated by further phases of the WTP will also depend on the water treatment technology selected, which may change during the LOM.

53



Dust suppression

Dust suppression on haul roads and wash-down water at the coal washing plant, conveyors and tips will be done utilising treated water from the WTP (not chlorinated). The expected demand for dust suppression is 219 000 m3/annum (or 600 m3/day).

Sewage treatment plant

During the construction phase, sewage will be collected in 8 m3 conservancy tanks at the contractor’s camp and office. These tanks will be emptied on a regular basis by a contractor and disposed of at an authorised sewage treatment facility.

During the operational phase, domestic and sewage waste water will be combined and treated in a sewage treatment plant located on the western side of the plant area. It will be a low maintenance biological filter treatment plant that will adequately cater for the workforce during the mine’s operational phase, assuming a treatment rate of 110 ℓ per person per day. The first module will be commissioned in 2015 at the start of Phase 2. A second module will be added in 2018 as the workforce start increasing. In 2023, at the start of Phase 2, a second rotor will be added to the second module (Semane, 2012).

The preferred technology is a Becon Watertech Model 300, which comprises of a septic tank with rotating biological discs. This is followed sequentially by a humus settlement tank and then a chlorination contact tank. The reactor tanks will be constructed of reinforced concrete (Semane, 2012).

Effluent from the sewage treatment plant will gravity feed into the Plant Area PCD, from where it will be treated in the WTP.

Sewage sludge will be removed at dedicated intervals by a contractor and disposed of at a licensed waste disposal facility.

Fuel storage facilities

Although not a waste steam, the storage of fuel could potentially impact on the water resource and therefore appropriate protection should be provided.

The design of the proposed fuel storage facilities is in accordance with standard petroleum local Codes of Practice, namely South African National Standards (SANS 1200, SANS 10131 & SANS 10089 etc.). Local standards and regulation requirements are included in design.

Since no South African standard exists for secondary containment tanks at this stage, international marks of approval and certification of equipment will be used as a guideline of compliance and quality (for example UL142) (Synergistics, 2012).

4.1.6 S21(j) Removing, discharging or disposing of water found underground if it is necessary for the efficient continuation of an activity or for the safety of people

During the construction phase, water will be pumped from the borrow pits developed at the box cut areas. These borrow pits need to be kept dry until coaling commences in 2015.

In 2023, the opencast mining activities will intersect the existing underground workings. Based on the preferred mine plan it is estimated that approximately 4.16 million m3 needs to be dewatered from the old underground workings before mining can commence. Initial dewatering from boreholes is scheduled for a period of four (4) years (2019 – 2022) at a rate of 86 870 m3/month (2 896 m3/day).

54



The total volume to be dewatered from the old underground workings is estimated at some 7.27 million m3. Therefore, following the initial dewatering, on-going dewatering will be required at an expected average rate of 6 900 m3/month (230 m3/day). The actual dewatering rate will however vary with time as mining progresses up- and downhill on the coal seam floor.

The position of the proposed dewatering pumps is indicated in Drawing C184-04-007 attached in Appendix A. Details of the pumping positions are provided in the water use table in Appendix A.

Water will be pumped from the advancing pit to ensure the continuation of mining. Over the LOM, groundwater will therefore be pumped at a rate that is sufficient to maintain groundwater levels below the “Environmental Safe Water Level” (ESWL). This is to maintain all polluted water in-pit and prevent surface and sub-surface decant into the receiving environment.

5. IMPACT ASSESSMENT

A detailed environmental impact assessment was undertaken for the proposed mine by Synergistics and is therefore not repeated here. The detailed report was submitted separately to the authorities by Synergistics (refer to report number S0403/NL/EIA01). A detailed description of the EIA process, studies undertaken and consultation undertaken are provided in the EIA report. A summary of the outcome of the impact assessment methodology and outcome is provided below.

5.1 Impact assessment methodology

The identification and description of impacts are described by Synergistics as follows (Synergistics, 2012):

The identification and assessment of environmental impacts is a multi-faceted process, using a combination of quantitative and qualitative descriptions and evaluations. It involves applying scientific measurements and professional judgement to determine the significance of environmental impacts associated with the proposed project. The process involves consideration of, inter alia: the purpose and need for the project; views and concerns of interested and affected parties; social and political norms, and general public interest.

The methodology used for assessing impacts associated with the proposed project follows the philosophy of environmental impact assessments, as described in the booklet Impact Significance, Integrated Environmental Management Information Series 5 (DEAT, 2002b). The philosophy is summarised by the following extracts:

“The impact magnitude [or intensity] and significance should as far as possible be determined by reference to legal requirements, accepted scientific standards or social acceptability. If no legislation or scientific standards are available, the EIA practitioner can evaluate impact magnitude based on clearly described criteria. Except for the exceeding of standards set by law or scientific knowledge, the description of significance is largely judgemental, subjective and variable. However, generic criteria can be used systematically to identify, predict, evaluate and determine the significance of impacts.” (DEAT, 2002b).

“Determining significance [of impacts] is ultimately a judgement call. Judgemental factors can be applied rigorously and consistently by displaying information related to an issue in a standard worksheet format.” (Haug et al., 1984 taken from DEAT, 2002b).

The purpose of undertaking an impact assessment is to ensure that the project proactively considers environmental issues as part of the project planning and decision-making processes throughout the project life cycle.

For each environmental component (i.e. visual, air quality, health), impacts will be identified and described in terms of: detectability / visibility of the impact, exposure of receptors to the impact, compliance with legislation and standards, other applicable

64



targets, limits or thresholds of concern, the level of change / intrusion imposed, and receptor sensitivity.

The impact assessment considered:

Physical, biological, social and economic components of the environment and their interrelationships;

The ability of receptors and affected parties to adapt to changes and thus maintain livelihoods after the operation has closed;

The effects of all stages of the project life cycle, including planning construction, operation, decommissioning and post closure must be considered;

Positive and negative environmental and social impacts;

Direct, indirect, induced and cumulative impacts;

Short- and long-duration impacts within the zone(s) of influence, and extreme events;

Potential trans-boundary effects and global impacts (e.g. air pollution, withdrawal of water from an inter-provincial waterway and emission of greenhouse gasses);

Potential impacts on local communities and/or other vulnerable individuals or groups;

Socio-political risks (e.g. political instability);

Impacts associated with supply chains where the resource(s) utilised by the project are sensitive.

The perceived sensitivity of receptors (people and/or receiving environment) will be professionally judged based on available scientific data (fact) and feedback from public participation processes (views, opinions, attitudes, and concerns) as documented in the Public Consultation Documentation and the Impact Rating criteria. The following impacts will be described:

Existing Impacts (Impacts of Existing Developments within Project Impact Area)

The proposed coal mine is located in an area affected by various historical and existing activities including mining, processing, agriculture, residential, major roads and highways and other linear infrastructure as well as the Kusile Power Station which is currently under construction.

The assessment of existing impacts will consider the current level of environmental degradation associated with existing developments, as well as developments under construction and new or planned developments that will be operational at implementation of New Largo and for which the impacts have been defined – these new developments will include the Kusile Power Station, the R545 road relocation and the Phola-Kusile Coal Conveyor.

Defining the current level of degradation associated with existing developments is essential to understand and enable the assessment of cumulative impacts (see Section 0 below). The assessment of existing impacts is qualitative and limited to the area of impact for the individual environmental components.

Incremental Impacts

Incremental impacts refers to the impacts of an activity looked at in isolation (impacts of an individual activity), thus not considering the combined, cumulative or synergistic impacts of the activity, or the cumulative impacts of the activity with other activities or

65



the existing impacts. The environmental impact report will describe the incremental impacts of the development alternatives.

No-go Development Impacts

The no-go development is considered as an alternative in the evaluation of development alternatives. In the environmental impact assessment the no-go development impacts would be similar to the existing impacts.

The no-go development will have high negative impacts on the cost and timing of coal supply to Kusile Power Station, delivery of electricity to the national grid, and associated impacts on the national economy and it is therefore assumed that if the proposed New Largo Colliery is not allowed to be developed, an alternative coal supply and transportation of that coal supply will have to be found to supply Kusile.

Cumulative Impacts

For this project, cumulative impacts will be determined as:

Existing Impacts + Incremental Impacts

= Cumulative Impacts

Existing impacts within the project area of impact for individual project

components (current level of degradation) associated with

existing developments.

Impacts of the proposed New Largo

Colliery and associated activities

and infrastructure

Existing impacts (current level of degradation)

associated with existing developments and developments under construction combined with the impacts of the proposed New

Largo Colliery and associated activities and infrastructure

In the assessment above, existing impacts often also represent the impacts of the no-go development option.

6. MITIGATION

6.1 Wetland mitigation/ offset

The draft EIA Report listed potential alternative wetland mitigation and offset plan options (see Section 5 of that report). These were regarded as preliminary since the preferred mine plan was not defined at that stage. The purpose of listing potential alternative wetland offset options was to stimulate debate and obtain comments from I&APs and authorities during the review of the draft EIA Report.

AAIC is however motivating that Mine Plan Version 6 is to be adopted as the preferred mine plan (refer to section 8.2 of the IWULA, as well as Section 5.3.3.2 of the final EIA Report). AAIC has appointed Wetland Consulting Services to develop a wetland offset plan based on Mine Plan Version 6. It will thus address offsets for wetlands affected by this Mine Plan.

DWA, DMR and MDEDET have not given clear feedback on their requirements for wetland offsets / off-site mitigation and on-site mitigation for affected wetlands. Offset plans are not legislated and it is uncertain what potential future legislation on this topic would require. No National or Mpumalanga provincial guidelines currently exist for wetland offset projects despite numerous offset projects already been undertaken within the Mpumalanga coalfields with varying degrees of success. Each has had its own approach which has been project specific depending on objectives, requirements of the authorities and the willingness of different mining houses to pursue and/or embrace the approach.

Recognizing the need for such guidelines, the SANBI Grasslands Programme recently funded a project entitled Towards a best-practice guideline for wetland offsets in South Africa (a draft version of these guidelines has been published). The technical guidelines contained in this report, which were developed specifically for coal mining in the Mpumalanga Highveld, will be considered in as part to the strategy to develop a wetland offset plan for New Largo Colliery. Developing an offset plan could be a lengthy process of which the first step is to develop a strategy according to which the offset plan would be developed. The strategy as proposed by WCS is presented in Appendix C.

Part of the strategy would be to involve I&APs, stakeholders and authorities, through the environmental monitoring committee, in the process, to evaluate comments and recommendations received, evaluate alternative offset options, and develop a final offset plan on the selected offset options (Synergistics, 2012).

6.2 Environmental Management Programme

The Environmental Management Programme (EMPr) compiled for the construction and operation phase of the New Largo Colliery Project is attached in Appendix C.

6.3 Method statement

A method statement for the construction through watercourses was developed by Semane and is attached in Appendix C.

69



7. MONITORING AND CONTROL

A detailed monitoring programme (surface water-, ground water-, and bio-monitoring, as well as technical monitoring) is included in section 6.6 of the IWWMP (attached as Appendix D).

The audit system described in section 6.10 of the IWWMP should be adhered to.

8. MOTIVATION FOR LICENCE APPLICATION

8.1 Authorisations required

8.1.1 Water uses requiring authorisation

A description of the water uses at the New Largo Colliery is provided in section 4.1.

8.1.2 Existing lawful water uses

There are no existing water uses as this is a proposed new mine.

A separate application has been submitted as part of the Phola-Kusile Overland Conveyor for the following water uses that are relevant to the New Largo Colliery (refer to the IWULA (JW117/11/C184) and IWWMP (JW118/11/C184) for that project). Should these be authorised, the water uses will continue as part of the New Largo Colliery in the long term:

Abstraction of water from boreholes for construction purposes (section 21(a));

Brine disposal facility and gypsum handling facility at the WTP (section 21(g));

Storage of water for dust suppression and fire water (a 1 Mℓ treated water reservoir will be located at the mobile WTP and two 420 kℓ fire tanks) (section 21(b));

Storage of potable water in 250 kℓ tank (section 21(b)); and

A pre-treatment storage facility (7.5 Mℓ raw water storage) at the mobile WTP for the storage of abstracted water from the old mine workings (section 21(g)).

8.1.3 Relevant exemptions

Application is herewith made for exemption from the following provisions of GN R 704 dated 4 June 1999:

Regulation 4(a): Locate or place any residue deposit, dam, reservoir together with any associated structure or any other facility within the 1:100 year floodline or within a horizontal distance of 100 m from any watercourse

Five of the pit polluted water transfer dams, the Admin Area PCD and the overburden dump are located within 100 m from wetlands.

None of the infrastructure is located within the 1:100 year floodline.

Regulation 4(b): Conduct underground or opencast mining, prospecting or any other operation or activity under or within the 1:50 year floodline or within a horizontal distance of 100 m from any watercourse

70



A number of watercourses will be mined. Mining will also take place within a number of watercourses and wetlands as indicated on Drawing number C184-04-002.

Regulation 4(c): Place or dispose of any residue or substance which causes or is likely to cause pollution of a water resource, in the working of any underground or opencast mine excavation

The majority of the discard will be disposed of in the mine voids (refer to section 4.1.5). Provision is also made for a surface discard dump (10 Mt) on a backfilled area for the disposal of discard in circumstances where in-pit discarding may not be possible (e.g. spontaneous combustion).

The motivation for the authorisation of water uses in terms of the NWA as contained in this report is relevant to this exemption application.

8.1.4 General authorisations

The storage of potable water from the WTP in the 1 Mℓ storage facility and the 250 kℓ potable water tanks fall within the ambit of the General Authorisations published in GN 399 dated 24 March 2006.

8.1.5 Other

The 1 200 Mℓ PCD exceeds 50 Mℓ and a wall height of 5 m and therefore the dam has to be registered with the DWA in terms of the Dam Safety Regulations published in GN R139 in Government Gazette 35062 of 24 February 2012.

AAIC will also register the STP and WTP as waterworks in terms of GN R2834 dated 27 December 1985 in terms of the Water Act, 1956.

8.1.6 Critical timeframes

As a part of the authority discussions the Phola – Kusile Overland Conveyor and the New Largo Colliery project, a request was made that consideration be given to a phased approach in the issuing of the water use licence. The main reason for this request is that some of the water uses, such as those associated with the construction phase are more urgent than others. The critical timeframes are indicated in Table 8.1.6(a) below. Due to the national importance of this project, it is requested that the DWA take cognisance of these time frames and prioritise this particular water use licence.

8.2 Technical and Financial Motivation for Mine Plan 6

Various mining alternatives were considered in order to minimise environmental impacts while maximising the coal resource. This included underground mining, but due to the shallow reserves, this option is not technically viable.

Mine Plan Version 6 covers an area of approximately 5 600 ha and presents AAIC’s optimised mine plan on which this water use licence application is based.

An alternative Mine Plan (Mine Plan Version 7), was developed which excludes a section of the surface rights area in the north to avoid mining of the large pan on the farm Honingkrantz 536 JR and covers an area of approximately 4 800 ha. Most of the coal found in the northern part of the coal reserve is of high quality. This mine plan presented challenges in terms of mine plan sequencing and blending of coal to provide the Kusile Power Station with an adequate supply of coal at the correct specification. AAIC investigated a number of iterations of Mine Plan Version 7 and Version 7d was assessed in the EIA (Synergistics, 2012).

Mine Plan Version 6 is motivated as the preferred option by AAIC based on the following:

8.2.1 Implications for Kusile Power Station

AAIC believes that by excluding the coal in the Honingkrantz pan area from the mine plan, the balance of coal supply to the Kusile Power Station will be significantly disturbed in terms of qualities and volumes over the life of the project. The boilers at the Kusile Power Station were designed on the average coal quality obtained from the whole resource, including the reserves in the Honingkrantz pan area. With the exclusion of the coal reserves in this area, approximately 14 years of effective coal blending at the New Largo Colliery are lost, which poses significant risks to coal quality supplied to the Kusile Power Station and the efficiency of the facility as a result (Synergistics, 2012).

Using Mine Plan Version 6, the New Largo Colliery can supply 642 Mt of coal to the Kusile Power Station over a period of 49 years at full production. This is reduced to

72



542 Mt of coal provided to the Kusile Power Station over a period of 43 years at full production.

If coal associated with the Honingkrantz pan area is excluded from the mining plan, New Largo Colliery will lose approximately 7 years off its total life of mine and Eskom will have to source the coal deficit elsewhere.

8.2.2 Technical considerations

The technical constraints and disadvantages associated with Mine Plan Version 7 are as follows (AAIC, 2012):

It is an unbalanced mine plan over life in terms of good vs poor quality coal. The aim is to balance the good and poor quality coal over the life of the mine, this way the benefits of blending and the need for processing is minimized;

It is an unbalanced mine plan over life in terms of remnant coal reserves vs virgin coal reserves. The production and coal supply risk is reduced if remnant and virgin mining is balanced over the life of the mine;

It is an unbalanced mine plan over life in terms high vs low strip ratio reserves. By excluding the low strip ratio Honingkrantz reserves production risks are added to the operation and costs will increase. The Honingkrantz portion that is excluded in Mine Plan 7 contains coal within both the No 2 and No 4 seams, which contributes to it being a low strip ratio reserve area (the mine will get more coal for the same amount of overburden removed). By excluding this Honingkrantz portion, approximately 70% of the available mining area in the north remains which only containing coal in the No 2 seam (high strip ratio);

Production and safety risk increases due to both draglines mining in the UG workings under high strip ratio conditions simultaneously. There are significant safety risks associated with mining remnant coal reserves eg spontaneous combustion, flooding, sink holes, high risk blasting activities (hot hole blasting) etc. The best way of designing a high production mine like New Largo Colliery is to balance the coal qualities, strip ratio, remnant reserves and production rates over the life of the mine;

Mining of remnant workings requires the establishment of a buffer within the highwall so as to prevent oxygen from ingressing into the UG workings causing spontaneous combustion. Because of this requirement one is limited in using explosives to “throw” / “cast” the overburden into position and the dragline is basically the only way of moving the material. Because of this more inefficient mining method the dragline rehandle percentage (additional material) increases from 12% to 28%. This significantly influences the coal exposure rate of the dragline. In mine plan version 7 the two draglines are both mining in the UG workings between years 2030 to 2040. In these years they produce about 10.5 million sales tonnes per annum as opposed to 12 million tonnes required by Kusile Power Station due to the increased rehandle. Kusile Power Station will therefore need to source the shortfall from a third party;

With dragline mining sufficient pit length is required in order to sequence and schedule all the mining activities eg drilling, blasting, coal loading etc. By excluding the Honingkrantz portion the pit length is reduced from 6km down to 1.8km. This significantly jeopardises the efficiency of the whole mining process, especially for the size of dragline/s New Largo Colliery will be utilizing;

Because of the reduced ability to blend poor with good quality coal, the only way of getting the coal within specification will be to process all of it. This causes

73



unnecessary yield losses, increased coal discard and further reduces the coal tonnes to Kusile Power Station; and

If sufficient good quality coal is available to blend with poor quality coal, the need for beneficiation can be reduced which in turn will reduce discards and operating costs.

8.2.3 Financial considerations

Financially Mine Plan Version 7 has major cost implications for Eskom in that the establishment capital and operating expenses are substantially higher compared to Mine Plan Version 6. The expected financial implications for Mine Plan Version 7d compared to Mine Plan Version 6 are indicated in Table 8.2.3(a). From the Table it can be seen that there is no real difference in the Net Present Value from an AAIC perspective in going for either Mine Plan Version 6 or 7d. The biggest implication will be on Eskom to pay an additional tw0-thirds of the increase in establishment capital (R924.5 million x 0.667 = R616.3 million) and then also to pay an additional R22.65 per tonne of coal produced at New Largo Colliery over the mine’s life of approximately 45 years.

The scheduling of capital projects such as the coal processing plant and water treatment plant will be required much earlier in Mine Plan Version 7d. A comparison of the scheduling of capital expenditure (expressed as January 2012 values) is provided in Table 8.2.3(b). This will have an impact on the coal prices, which will ultimately be passed onto the electricity consumers.

8.3 Comparison of Mine Plan Version 6 and Mine Plan Version 7d based on environmental considerations

A detailed comparison of the environmental impacts associated with the two mine plans considered was done in the EIR by Synergistics. A summary of pertinent aspects related to the water resources are provided below.

8.3.1 Wetlands

The types of wetlands and their extent that will effectively be lost if Mine Plan Version 6 is implemented are indicated in Table 8.3.1(a). The area of wetland loss within the footprint of the opencast area is approximately 608 ha (WCS, 2011).

Table 8.3.1(a): Types of wetlands lost due to Mine Plan Version 6

Description

Wetland types

Total area (ha) Hillslope seepage

(ha)

(ha)

Dams (ha)

Coal reserve 413 32 160 3 608

Not directly impacted 565 381 4 42 992

If Mine Plan Version 7d is implemented, the area of wetland lost is reduced to 468 ha. It is expected that this area contributes to maintaining the ecosystems associated with the quartzite ridges, downstream seepage wetlands, as well as the associated landscapes. These catchments also contribute to the high quality water (sulphate concentrations below 10 mg/ℓ) (WCS, 2011).

If the Honingkrantz pan is utilised to mitigate impacts of Mine Plan Version 6, the long-term future of the pan will have to be looked into carefully. The extensive sand mining operations that are taking place within close proximity to the Honingkrantz pan are of concern in the sustainability of this option as an off-set project (Synergistics, 2012).

8.3.2 Catchment yield

75



The Version 7d mine plan causes a reduction in catchment yield of 0.46% as compared to Version 6 which causes a reduction of 0.5%.

8.3.3 Water balance

Based on the water balance, the post closure water make for Mine Plan Version 6 is 13% greater than for Mine Plan Version 7d (Version 6 water make post closure is approximately 22 100 m3/day and Version 7d is 19 200 m3/day). This equates to the potential salt loading from the mine being 13% greater for Version 6 than for Version 7d (J&W, 2012).

On average, over the life of mine, it is expected that clean water will be discharged to the system at an average rate of approximately 13 000 m3/day for Version 6 and 12 200 m3/day for Version 7d. Compared with the expected loss of yield due to the mining activities (2 600 m3/day), the net increase is conservatively estimated to be in the order of some 10 400 m3/day for Version 6 and 9 600 m3/day for Version 7d. This relates to an increase in MAR (i.e. over the mining area affected by mining activities) of some 400% for Version 6 and 369% for Version 7d (J&W, 2012).

8.3.4 Ecosystem services

The implication on Mine Plan Version 6 on ecosystem services was assessed as follows by Synergistics (Synergistics, 2012):

To effectively compare the value of mining coal to the value of aquatic ecosystem services would require a strategic assessment of the coal resources and aquatic ecosystems and wetlands in South Africa, including the need for coal in electricity generation and associated economic development, and the future of economic developments which are dependent on ecosystem services. A national strategic approach to mining and the protection of ecosystems is therefore required, which will require close cooperation between the DMR, DWA and DEA (representing mining, water and the environment respectively).

In the absence of such a strategy, and with the uncertainties around future land uses such as agriculture, sand mining and coal mining in the area around the Kusile Power Station and the proposed New Largo Colliery, the ability of the Honingkrantz pan to maintain its ecosystem services value in the long-term cannot be guaranteed even if Mine Plan Version 7 is adopted. It is therefore not realistic to attempt to compare the monetary value of the coal mine versus the value of the ecosystem services.

Mine Plan Version 7 will repeat what is currently occurring at various coal mines in South Africa – where mines are trying to, or are expected to as part of the EIA and IWULA approval processes, adapt their mine plans in order to protect a portion of the wetlands within their mining right areas. In the absence of a strategic plan, this ad hoc approach is an attempt by mines and the EIA and IWULA approval authorities to protect wetlands and associated ecosystems found within mining reserve areas. Unfortunately, this mine-by-mine / project-by-project basis of conserving wetlands remain ad hoc and is often resulting in a series of fragmented wetland habitats surrounded by mining and other incompatible land uses. This approach however is definitely better than nothing, but it cannot replace the need for a more strategic approach to guiding and managing coal mining and the protection of wetlands and other sensitive habitats in South Africa.

In the absence of a strategic plan for protecting wetlands and their associated ecosystem services, it is not realistic for AAIC or the EAP responsible for the New Largo Colliery EIA to provide a credible comparison of the monetary value of mining of the coal associated with the Honingkrantz pan versus the monetary value of the long-

76



term ecosystem services value that the pan could sustain in future. This is even more relevant due to the fact that that the future of the Honingkrantz pan is uncertain and questionable – even if an Alternative Mine Plan was adopted (i.e. Mine Plan Version 7D). For example:

It is questionable if the area around Honingkrantz pan that is excluded from Mine Plan Version 7 will safeguard the future of the large pan and its ability to sustain the ecosystem services provided by the plan;

If the Honingkrantz pan area is not mined by AAIC, AAIC will in effect give up (or lose) their mining right over the area. This would give other mining companies the opportunity to apply for a mining right over this area in the future;

Sand mining in the vicinity of the pan is continuing to impact on the pan;

The future of coal mining and plans by other mining companies to mine the coal reserves in close proximity to New Largo is uncertain, but based on current information in the public domain, it is likely that other coal mines may be established in future, which would affect areas downstream of the Honingkrantz plan, further questioning the future value of the pan’s ecosystem services – again highlighting a strategic rather than a project-by project approach to wetland protection and conservation.

In addition to these questions regarding the sustainability of the pan and it’s ecosystem services, it has to be considered that the ~100 Mt of coal has to found from elsewhere, and it is questionable if the coal) associated with New Largo.

AAIC has committed to a number of key environmental management measures. The two key ones are:

A progressive soil management and rehabilitation plan, more advanced that most other coal mines, especially mines using draglines. The soil management and rehabilitation adopted for New Largo increases the potential for the establishment of agricultural land uses post mining (this rehabilitation plan is discussed in detail in sections 4.1.1 and 5.7.2 of the EIR); and

A water treatment plant to treat water impacted by the mine and past mining activities within the mining area from day one, throughout the life of the mine and post closure until such time that monitoring results prove that treatment is no longer necessary.

The same cannot be guaranteed for the alternative mine(s) where the ~100 Mt of coal will have to be sourced.

8.4 Section 27 motivation

8.4.1 Existing lawful water uses

All the water uses associated with the proposed New Largo Colliery is new water uses which require authorisation in terms of the NWA. Water uses associated with the Phola-Kusile Overland Conveyor is discussed in section 8.1.2.

8.4.2 Redress the results of past racial and gender discrimination

AAIC is a broad-based black economic empowerment company in which Anglo American has a 73% shareholding and was formed in 2007. AAIC has a number of domestic and export-focused coal operations, including Kriel Colliery and Zibulo multi-product mine. Greenfield projects include New Largo, Elders and Heidelberg.

AAIC is led by the Lithemba Consortium and Pamodzi Coal, and has a beneficiary base that will benefit in excess of 27 000 individuals, the majority of whom are female Historically Disadvantaged South Africans. Women’s Development Bank Investment Holdings is also a shareholder.

An independent broad-based Community Trust that will benefit historically disadvantaged communities around AAIC operations has been formed (AATC, 2011).

A copy of the Social and Labour Plan for the New Largo Colliery is attached in the IWWMP, in which more details are provided of these initiatives.

8.4.3 Efficient and beneficial use of water in the public interest

South Africa’s national electricity utility, Eskom, currently relies on coal fired power stations to produce approximately 95% of the electricity generated in South Africa. Therefore, until alternative energy generation options are implemented on a large enough scale, Eskom is totally dependent on coal mining (Synergistics, 2011). The Kusile Power Station is aimed at meeting the growing energy demand in South Africa.

AAIC and Eskom maintain that the proposed New Largo Colliery is needed to:

Ensure the supply of a secure, long-term supply of coal to the Kusile Power Station;

Enable the Kusile Power Station to provide power to the national electricity grid on schedule;

Address power shortages in the national grid since there are no short to medium term options to replace the Kusile Power Station’s energy generation capacity at a national level;

Avoid negative impacts of energy shortages on national economic growth and development;

Achieve the objectives and targets set out in IRP2010 and the National Government’s national electricity generation strategy (Synergistics, 2012).

The water uses associated with the New Largo Colliery will therefore assist in ensuring the Eskom meets its objectives in terms of supplying in the electricity need of the country.

78



8.4.4 Socio economic impact of the water uses if authorised or of the failure to authorise the water uses

The total value of lost current economic activity totals R 707 million over 45 years as a result of the mining activity expanding in the mining area. However, the estimated turnover value of coal mining operations over the 45 years is estimated at R 48.9 billion (2011 values). The gained economic activity in mining is therefore much higher than the lost economic activity valued (Demacon, 2012).

Electricity supply is a critical issue in South Africa and the proposed project is expected to improve the stability of the service. From a greater societal perspective the project will therefore have a positive impact. Concerns do however exist about the long term impact on food security due to cumulative loss of high potential agricultural land. The proposed project will take place in an area surrounded by industrial development, and many of the impacts are already taking place and therefore stakeholders are familiar with potential impacts. A small number of stakeholders will bear the majority of impacts of a project that is in the interest of the country at large. The largest number of impacts will result from a change in land use and an influx of people (Ptersa, 2011).

8.4.5 Applicable catchment management strategy

The catchment management strategy for the Olifants River Water Management Area has not been developed. However, a number of studies and planning initiatives have been undertaken by the DWA for this area. This includes inter alia:

Development of an Interim Water Quality Management Plan for the Klipspruit catchment (1995);

Development of a Water Quality Management Plan for the Witbank Dam and Middelburg Dam catchments (1993);

Assessment of the impact of abandoned and defunct coal mines within the Loskop Dam Catchment (2001);

Ecological Water Requirements Assessment for the Olifants River (2001);

Validation study for the Olifants WMA (2006);

Development of a Reconciliation Strategy for the Olifants WMA;

Classification of significant water resources in the Olifants WMA (project commenced 2011).

8.4.6 Impact of the water uses on the water resource and on other water users

A detailed impact assessment was undertaken for the New Largo Colliery as described in section 5. Key findings of the impact assessment are as follows (Synergistics, 2012):

The New Largo Colliery is proposed to meet the future demand for coal at the Kusile power station. Kusile will require a constant supply of ~17 Mt per year over a life span of 55+ years. This requires a massive coal reserve. The New Largo Colliery coal reserve is located directly to the east of Kusile, between the N4 highway in the north and the N12 highway in the south, with a small portion of the coal reserve found to the south of the N12 highway.

With the design and location of Kusile, it was always intended that the New Largo coal reserve would supply the base load coal to Kusile. The boilers of Kusile were planned based on the coal quality average obtained from the whole of the New Largo coal

79



reserve including the Honingkrantz reserves. In essence – Kusile was designed in accordance with Mine Plan Version 6 coal quality average.

The larger part of the coal reserve is recognised to be of poorer quality which requires some form of beneficiation in order to improve the coal quality to the requirements stipulated in the coal sale agreement between AAIC and Eskom. The coal sale agreement stipulations are based on the design of Kusile.

New Largo Colliery will be an extensive opencast coal mine and, as for any coal mine of this scale, it would be associated with impacts of a very high significance that will require careful management and specialised long-term mitigation at considerable cost. Some of the impacts and mitigation will remain a risk and a cost for many years after mining has ceased.

The project will impact on a number of wetlands within in the mining area. Although alternative mine plans were evaluated to minimise impacts on wetlands, AAIC maintains that there are serious risks associated with the alternative mine plans and that their base case mine plan (Mine Plan Version 6) should be adopted as the preferred mine plan. AAIC has appointed Wetland Consulting Services to develop a wetland offset plan for wetlands affected by Mine Plan Version 6. The strategy as proposed by Wetland Consulting Services and adopted by AAIC is presented in Appendix U. Part of the strategy would be to involve I&APs, stakeholders and authorities through an environmental monitoring committee in the development of an offset plan.

Coal mines are often associated with significant long-term impacts on water quality. AAIC has committed to develop a water treatment plant to treat water impacted by the mine and past mining activities within the mining area from day one, throughout the life of the mine and post closure, until such time that monitoring results prove that treatment is no longer necessary. Although the active treatment of water will assist with reducing this impact by returning clean water to the streams and total stream flow is predicted to increase, the seasonality of the streams will be affected, which will impact on downstream wetlands and aquatic habitats.

Large parts of the mining have been cultivated in recent years. AAIC has adopted a soil management and rehabilitation plan that are more advanced that for most other coal mines, especially those using draglines. The adopted soil management and rehabilitation that was developed based on recommendations from various specialists on the EIA study team and comments received from authorities and I&APs (details of the plan presented in Section 4.11). The plan optimises the potential for the establishment of agricultural land uses post mining and should also reduce the need for post closure water treatment. Based on the adopted soil management and rehabilitation plan, a conceptual end land use plan was developed which indicates that it would be possible to achieve no net loss of food production and income generation from agriculture. At this stage, the conceptual end land plan was developed to optimise the use of the land for agriculture but obviously this plan will be revised and updated over the life of the mine in consultation with the I&APs and the environmental monitoring committee. From a biodiversity protection viewpoint, this plan support the ecological specialists recommendations to be done in such a manner that it limits the need to transform other areas for agricultural food production.

The various impacts of the New Largo Colliery are discussed in detail in Section 8 and have been rated, for all project activities and project phases, in Section 9, these sections clearly indicate that there are substantial negative impacts as well as substantial positive impacts.

80



Most of the negative social impacts of a project such as New Largo Colliery are often experienced locally by the people living in close proximity to the project. Impacts on the lives and livelihood of the project’s future neighbours will require pro-active mitigation (i.e. measures to avoid, reduce, manage and /or compensate for impacts). The EMP includes clear measures to address the need for continued stakeholder engagement, and deal with complaints, claims and potential disputes. It also allows for the establishment of an environmental monitoring committee.

When considering the impacts of the proposed New Largo Colliery, the importance of the project in the national (South African) interest must be considered. New Largo Colliery forms part of a much larger value chain for electricity production in South Africa. The mining development is an investment of R21.3 billion, and represent a part of the investment including the Kusile Power Station and conveyor belts that will invest over R90 billion in the local and national economy. All these projects are needed to ensure that electricity supply is increased to facilitate economic growth for the national economy.

The New Largo coal reserve consists of areas with high quality coal and areas with lower quality coal, which will have to be blended in order to ensure a consistent supply of coal that meets Eskom’s quality requirements for coal supply to Kusile, which uses pulverised coal combustion technology. There are several portions of the New Largo coal reserve where mining by underground methods has taken place in the past, the largest and most extensive being the now defunct underground New Largo Coal Mine. It is estimated that approximately 20% of the reserve area comprises of defunct collieries with reserves contained both in pillars and roof and/or floor of the workings. About ~45 Mt of coal over an area of 1 500 hectares have been extracted by previous mining activities.

Collapse of old underground workings and spontaneous combustion poses a hazard to both the workforce and equipment if not adequately managed. AAIC has extensive experience in opencast mining of previously mined underground workings and safe work practices employed at these collieries will be implemented. However, the presence of the old underground workings do pose significant limitations on the mining methods chosen as well as on mine scheduling / sequencing to achieve safe mining conditions and achieve the required coal qualities for Kusile. AAIC views opencast mining using draglines, supported by small shovel and truck operations, as the only viable mining method to recover coal reserves remaining in areas previously mined by underground methods and to produce the vast quantities of coal required by Kusile.

In terms of scale and tonnages required, it is the opinion of the Environmental Assessment Practitioner that there is no alternative coal mine, or combination of smaller coal mines, that could supply this coal on schedule and at the correct grade, quality and quantities – with less environmental impacts than those associated with the New Largo Colliery. In the light of the discussions in Section 1.5 (Development Need and Desirability) and Section 8 (Environmental Impact Assessment) of the report, it is clear that New Largo Colliery is the best suited coal reserve to supply Kusile. This conclusion was reached based on the Environmental Assessment Practitioner’s professional experience working with coal mines throughout all the major coal fields in Mpumalanga, Kwa-Zulu Natal and Limpopo provinces of South Africa.

The Environmental Assessment Practitioner for this project is of the opinion that there are no notable uncertainties and knowledge gaps that should affect the approval of the New Largo Colliery project.

Regardless of the obvious need for the project to be approved timeously to supply coal to Kusile, and to continue to provide a constant supply of coal to Kusile, AAIC need to

81



keep to the strategy for developing a wetland mitigation and offset plan and summarised in the EMP.

The EAP is recommending that the project be approved by government subject to the implementation of the EMP.

8.4.7 Class and resource quality objectives

In 2010 the DWA identified the need to undertake the classification of significant water resources in the Olifants WMA in accordance with the Water Resources Classification System and has commissioned Golder Associates Africa to assist with the classification process. Zitholele Consulting is assisting with the public consultation process of this project. The determination of management classes of the significant water resources in the Olifants WMA will describe the desired condition of the resource, and conversely, the degree to which it can be utilised by incorporating the economic, social and ecological goals of the users and stakeholders (DWA, 2011). This project is still in process and the management class of water resources in the Olifants WMA has therefore not been concluded yet.

The Directorate National Water Resource Planning (DNWRP) of the (then) Department of Water Affairs and Forestry (DWAF) developed a water quality management strategy for the Upper and Middle Olifants River catchment, which was published in 2009 (DNWRP, 2009). Interim Resource Water Quality Objectives (RWQO) were determined that will be reviewed once the water quality component of the Ecological Reserve has been updated (in five years’ time) (DNWRP, 2009).

Quaternary catchment B20F is considered to have rehabilitation potential, while quaternary catchment B20G is considered transformed in terms of the river component of the National Spatial Biodiversity Assessment (EcoInfo, 2011).

8.4.8 Investments already made and to be made by the water user

Capex for New Largo Colliery (mine and WTP): R 21.3 billion

Capex for R545 re-alignment: R 196 million (AAIC, 2012).

According to AAIC, the capital cost for the WTP may vary between R 20 – R 25 million/Mℓ and operational costs between R 4.50 and R 7.00/m3 treated at current values (Synergistics, 2012).

8.4.9 Strategic importance of water uses

South Africa’s national electricity utility, Eskom, currently relies on coal fired power stations to produce approximately 95% of the electricity generated in South Africa. Therefore, until alternative energy generation options are implemented on a large enough scale, Eskom is totally dependent on coal mining (Synergistics, 2011). The Kusile Power Station is aimed at meeting the growing energy demand in South Africa.

AAIC and Eskom maintain that the proposed New Largo Colliery is needed to:

Ensure the supply of a secure, long-term supply of coal to the Kusile Power Station;

Enable the Kusile Power Station to provide power to the national electricity grid on schedule;

Address power shortages in the national grid since there are no short to medium term options to replace the Kusile Power Station’s energy generation capacity at a national level;

82



Avoid negative impacts of energy shortages on national economic growth and development;

Achieve the objectives and targets set out in IRP2010 and the National Government’s national electricity generation strategy (Synergistics, 2012).

8.4.10 Quality of water resource which may be required for the Reserve and to meet international obligations

The Reserve Determination will be completed by May 2013 and the final discharge from the WTP should be based on the outcome of this study.

8.4.11 Probable duration of any undertaking for which a water use is to be authorised

The New Largo Colliery will be operational for approximately 50 years. Some of the water uses, such as the watercourse crossings and mining within wetlands are permanent water uses. Treatment of impacted water and the discharge into the water resource is expected to continue well beyond the life of mine.

Both these documents included a response sheet and a request for written comments. The BID distributed in July 2011 also highlighted the proposed New Largo Colliery project and invited participants to participate in the EIA process.

9.1.7 General Public Meetings

General public meetings were held on 12 and 13 May 2011 at the ‘Ons Huisie’ guesthouse situated next to the Kendal/Balmoral road.

A meeting was also held on 20 May 2011 with Dr Koos Pretorius of the Federation for a Sustainable Environment, Ms Carol Wentzel and Ms Annamie Duvenhage from the Bronkhorstspruit and Wilge River Conservation Association in Witbank to discuss the proposed project with them.

A water focus group meeting was held on 26 July 2011 that was attended by almost 80 people. Concerns regarding water resources were discussed. This meeting came

86



about through a special request by stakeholders during the public meetings which were held on 12 and 13 May 2011.

9.1.8 Public feedback meetings and Open Day during the EIA Phase

During the EIA phase of the study, an open day and two public meetings were held on 6 March 2012 at the El Toro Conference Facility near Kendal Power Station where the results of the specialist studies and the evaluation of development alternatives, the EMP and the integrated water and waste management plan were presented. Registered I&APs were directly invited to attend the meetings and the open house sessions on that day. An open day and two meetings were held on this day to cater for those I&APs who could attend during the day and for those who could attend in the evening.

At these meetings, the Environmental Assessment Practitioner presented a comparative assessment of Mine Plan Version 6 and Version 7 and AAIC presented their motivation for maintaining Mine Plan Version 6 as their preferred mine plan. The team of environmental specialists were available with summarised presentations on their study results and large maps on the project zone of influence were also available to facilitate discussion.

9.1.9 Consultation with Landowners and Mining / Prospecting Right Holders

AAIC is in discussion with the owners of the affected properties:

Two meetings were held with Malachite Mining regarding access to their property should the proposed developments be implemented;

AAIC is in on-going discussions with Mr. Truter (from Truter Boerdery Trust), Mr. Cherry, SANRAL, Ingwe Coal Corporation and Eskom, directly affected landowners;

AAIC is in the process of requesting property valuations on directly affected land owned by Witbank Brickworks and Mr Van Heerden. A meeting was held between AAIC and Witbank Brickworks on 15 November 2011 regarding property purchases;

AAIC is in discussions with tenants and occupiers of land owned by AAIC;

AAIC is in on-going discussions with Mr Byrne (from Kendal Poultry Farm), a directly affected landowner, who is in the process of obtaining valuation on his properties;

Respective negotiations regarding property purchases are in process between AAIC and directly affected landowners, Ms Roos and Macphail Distributors;

A purchase agreement has been reached between AAIC and Mr Strick a directly affected farmer.

9.1.10 Consultation about the proposed Water Treatment Plants and the Waste Management License Application Process

The need for a waste management license was conveyed to I&APs and authorities at all of the public and authority meetings. During the initial meetings, the development of mobile WTPs and development of a permanent WTP later in the life of New Largo Colliery were presented as an integral part of the New Largo Colliery.

During July 2011, I&APs were informed of AAIC’s intention to develop the first 4 Mℓ mobile WTP at an earlier date to treat water currently found in the old mine workings and to supply a portion of the water to the Phola-Kusile Coal Conveyor for dust suppression and fire protection. Since this first 4Mℓ mobile WTP will be commissioned

87



before the New Largo Colliery, it will form part of a separate WML application. The second mobile WTP and waste activities associated with the mine form part of the WML application for New Largo Colliery.

A notification letter distributed to I&APs on 30 September 2011 included the announcement of the separate WML application for the first 4 Mℓ mobile WTP and its associated wastes. Site notices were placed on 27 October and an advertisement was published on 20 November 2011 to notify stakeholders of the proposed treatment plant and to invite comments from I&APs.

9.1.14 Review of the IWULA and IWWMP

The draft IWULA and IWWMP were made available for public and authority review from 12 March to 13 April 2012 (it should be noted that the water uses associated with the R545 re-alignment and the New Largo Colliery were combined into one IWULA at that stage. The decision was only taken to split it into two applications following a meeting with the DWA on 19 April 2012, as a result of the fact that the DPWRT will be the ultimate owner of the R545 road). All registered I&APs were notified in writing of the availability of the document for review, and they were requested to submit comments.

Electronic versions of the reports were published on www.synergistics.co.za and www.zitholele.co.za and were circulated to all landowners and registered I&APs who provided an e-mail address.

9.2 Issues and responses

Detailed issues and response register is contained in the EIA Report. In summary, the issues related to water resources are as follows (Synergistics, 2012):

Effects on water regime due to impact on wetlands;

Impacts on water quality in streams and boreholes and impacts on neighbours and downstream users;

Acid mine drainage / contaminated mine water (decant) reaching downstream environments;

Impacts on boreholes and springs and aquifers due to blasting and dewatering;

Impacts due to the disposal of coal discard in mine pit and/or on surface;

Impacts of old oil storage in nearby old underground mine workings;

Water monitoring positions, timeframes and adequacy of monitoring network to assess impacts on environment and neighbours;

Compensation for impacts on neighbours;

Recourse if neighbours are impacted but have difficulty proving the impact.

AAIC has committed to the installation of a WTP to treat all polluted water from start of project. The following concerns were raised regarding the treatment of water as mitigation measure for water quality management:

The WTP will have to stay in operation and be viable for many years (100+ years, or when water treatment is no longer required) after closure of the mine;

Financial provisions for management of water impacts during life of the mine for many years after closure;

What would the real capital and operational costs be?

Who will pay for it, especially many years after closure?

If the base case is to release water to streams, how will the operation of the WTP be financed as water will not be sold?

Future long-term energy source for WTP;

Seasonality of flow would be lost if constant releases from WTP will be made;

Positions of water released from the WTP should be chosen carefully to avoid erosion and impacts on downstream environments of the various streams affected;

The findings of the Reserve Determination should be used to determine points and quantities for release of treated water;

Ability of treatment plant to treat water contaminated due to stored bunker oil (subsequent to the assessment, AAIC confirmed with Oil Pollution Control, a subsidiary of the Strategic Fuel Fund, that the oil has been removed from the bunkers);

The impacts on streams and wetlands due to the change to topography (lowering of the open cast mining area after mining) should be considered.

Issues related to the impact on wetlands are as follows (Synergistics, 2012):

Impacts on biodiversity due to impacts on wetlands;

91



Mitigation of impacts on wetland;

Recreation / replacement of wetlands that will be destroyed;

There is a negative track record for recreation of wetlands in mined areas. Recreation as mitigation measure can therefore not be guaranteed;

Wetland offsets, in form of wetland rehabilitation in same catchment, should be seen as a last resort;

Potential wetland offsets were proposed;

Alternatives for mitigation of wetland impacts (not just offsets) should be considered;

Benefits of coal extracted from wetlands and surroundings to be assessed in light of permanent loss of wetlands from a water regime and biodiversity point of view;

Function of wetlands, i.e. water regime and biodiversity role, to be considered when mitigation options are considered;

Economics and sustainability of wetland mitigation to be compared to value of coal extracted from affected areas;

Consideration should be given to the exclusion of wetlands and watercourses from the mining plan;

Wetlands should be prioritised based on data bases developed by the DWA;

Buffer zones around wetlands should be considered;

The northern section of the mining area appears to be the most sensitive (around northern pan) – this area should be mined last and not first as per the current mine plan (version 6);

Mitigation measures for impact on the northern pan should be successfully implemented before disturbance of this area;

Alternative Mine Plans should be tabled to demonstrate efforts to exclude the most sensitive areas.

Detailed responses to all the issues raised during the EIA process are provided in Appendix D1 of the Final EIR compiled and submitted by Synergistics.

10. CONCLUSION AND RECOMMENDATION

10.1 Conclusion

The New Largo Colliery will provide coal to the Kusile Power Station, which is of strategic importance in the current long-term power supply strategy for the country.

It will be an extensive opencast coal mine associated with impacts of a very high significance with regard to surface and groundwater that will require careful management and specialised long-term mitigation at considerable cost. In the opinion of the Environmental Assessment Practitioner, there is no alternative coal mine, or combination of smaller coal mines, that could supply the Kusile Power Station with coal on schedule and at the correct grade, quality and quantities – with less environmental impacts than those associated with the New Largo Colliery (Synergistics, 2012). It is therefore regarded as the best suited coal reserve to supply the Kusile Power Station

92



and based on this, it is recommend that an integrated water use licence for Mine Plan Version 6 be granted.

A number of watercourses will be destroyed or impacted on due to the opencast mining activities. Although alternative mine plans were evaluated to minimise impacts on wetlands, AAIC maintains that there are serious risks associated with the alternative mine plans and that their base case mine plan (Mine Plan Version 6) should be adopted as the preferred mine plan. AAIC has therefore appointed Wetland Consulting Services to develop a wetland offset strategy based on Mine Plan Version 6 being implemented. Developing an offset plan for New Largo could be a lengthy process of which the first step is to develop a strategy according to which the offset plan would be developed. Involvement of I&APs, stakeholders and authorities through the environmental monitoring committee in this process, to evaluate comments and recommendations, evaluate alternative offset options, and develop a final offset plan on the selected offset options is crucial (Synergistics, 2012).

10.2 Recommended licence conditions

The following conditions are recommended for inclusion in the water use licence:

The water balance should be continuously monitored and reviewed on an annual basis, to enable calibration. This information should be used to continually review the scheduling of the WTP, as well as the dirty water storage requirements;

A waste inventory should be developed one year after the mine becomes operational. This should be used to develop an integrated waste management plan;

The IWWMP should be reviewed and updated annually to take cognisance of any changes in the water balance, any resultant changes in the water and waste management measures, as well as changes to the mining schedule or development;

Specific method statements should be developed for construction or mining activities within, or close to watercourses. This should be done in conjunction with a wetland and/or aquatic specialist and should be implemented during the construction phase;

Monitoring of surface water, groundwater and the aquatic ecosystem should be done according to the monitoring programme outlined in the IWWMP;

Annual external audits should be conducted of compliance with licence and EMPr conditions;

A catchment management forum must be established in order that the cumulative impacts of all role-players in MU 20 and 21 for the Saalklapspruit, and MU 22 for the Wilge River catchment can be managed in an integrated manner in order to ensure compliance with the RWQO;

An Operations, Maintenance and Emergency Preparedness Manual should be developed for all water and waste containment facilities;

The strategy for the development of a wetland offset plan as proposed by WCS should be implemented.

NOTES:

1. NC: not certain. Discharge to NLD13 will cease upon mine closure when the Admin area is rehabilitated. The other discharge points will be used post closure since water treatment will continue. The end date of discharge to these points cannot be predicted at this stage

2. Maximum discharge will be at the end of mining, just before closure when the mine has maximum water make. Total volume per year therefore calculated as the maximum water make (in 2060) proportioned according to discharge allocation in C184-MP-Disch-Rev0 (attached as Appendix B)

3. Calculated as the maximum discharge from the WTP (maximum treatment rate x peak factor x discharge allocation) 4. Based on treatment at full capacity until the 1 200 Mℓ dam runs dry, assuming average rainfall in 2060. These values disregard discharge requirements in terms of the Reserve and the need to manage the water level in the 1 200 Mℓ dam during the

winter months to ensure that the water demand on the mine is met. 5. Calculate from average monthly rainfall, considering the wettest month
