1.5 PURPOSE OF THE IWWMP
The purpose of the IWWMP is to provide the Department of Water Affairs and Sanitation (DWS) with the necessary information to amend the integrated water use license for the Uitkomst Colliery, to correctly reflect the current and future water uses on site.
The objectives of the IWWMP are to achieve holistic, resource focused water and waste management on site, as well as to achieve compliance with the NWA. It also expands on a monitoring system which will allow early detection of impacts, as well as proposed actions that should be considered should monitoring activities indicate environmental issues.
As monitoring activities proceed and annual audits are conducted, on-site management and monitoring may change. Changes may also occur through new legislation, new technology or improved monitoring or management practices. This will result in the IWWMP becoming an active document which will be regularly updated through the life of the mine.
In summary the IWWMP is:
A legal requirement; Takes into consideration: o Legislative requirements, such as GN704; o Environmental requirements such as the water quality guidelines and resource objectives; o Best practices available at the time for implementation and design of management features and water- and waste-related infrastructure and activities; o Uitkomst Colliery’s environmental policies; and o Closure objectives for the site.

Resource Estimate: 26 Million tons
Production Rate: 65,000 tons/month
Plant Design 75,000 tons/month Capacity:
Estimated Life of 18 years Mine:
Depth of Mining: Average depth 135 m Gus coal seam varies from 18 – 355 m
2.2 EXTENT OF ACTIVITY
The overall mineral area comprises of 11,169.0386 Ha, of which it is anticipated that approximately 1,100 Ha will be affected by underground mining. Plan 2 indicates the extent of the mining right area in relation to the underground mining and Adit areas.
Infrastructure and surface disturbance will be limited to the Adit areas, with the exception of a 22kv overhead powerline that will run from the Klipspruit Adit to the Uitkomst Adit.
2.3 KEY ACTIVITY RELATED PROCESSES & PRODUCTS
Coal is mined via underground bord-and-pillar methods. Mined coal is conveyed to surface where it is temporarily stockpiled before being fed to the existing plant for processing. The coal is fed to the primary crusher where it is crushed and then transported via conveyor to the screening section in order to achieve the required product specifications. Oversized material is sent to the secondary crushing section. Correctly sized material is then fed to the beneficiation plant.
The beneficiation plant includes a spiral section (-1.5 mm) and a dense medium cyclone section (+1.5 to -40mm). A product screening section provides the different size gradings for the various markets.

UITKOMST COLLIERY: IWWMP
The discard from the plant is trucked to the co-disposal facility, while slurry is pumped to surface ponds on the co-disposal facility. The slurry is reclaimed and sold to interested markets where possible. This co-disposal facility is also referred to as the Mine
Residue Disposal Site (MRDS). The figure below depicts a simplified diagram of the key activity processes (SLR, 2015).

2.5 ACTIVITY INFRASTRUCTURE DESCRIPTION
Uitkomst Colliery can essentially be divided into two sections, namely:
South Mine; and Klipspruit Mine The section below details the infrastructure associated with each of these areas.
2.5.1 South Mine
Operations commenced at the South Mine in 2006, the underground workings are accessed via a boxcut-adit (known as the Uitkomst Adit or Adit 1) cut into the hill slope in a north westerly direction. The adit was constructed into the mountain to allow for access to the Gus coal seam. Topsoil has been removed and stockpiled to the north east of the boxcut. The hards and softs from the boxcut were utilised to construct a platform on the low wall side (south east side) of the boxcut to accommodate the coal processing and load out activities.
The Adit and associated infrastructure area comprises approximately 37 Ha, and includes the following infrastructure (seeFigure 2):
Box cut and adit; Soils and spoils stockpiles; Crushing and Screening plant; Beneficiation plant; Product and RoM stockpiles; MRDS/Co-Disposal Dump; Settling dams; RWD; PCD; Security, access control and weighbridge; Offices, workshops and contractors laydown area; Change houses, lamp room, laundry and ablution facilities;
11 | P a g e
UITKOMST COLLIERY: IWWMP
Scrap yard and waste storage area; and Fuel and oil storage area. No additional infrastructure is envisaged for this area. It is however expected that the MRDS will need to be extended in future to cater for the additional life of mine (LoM).
The water management facilities, including the pollution control dam (PCD) and Return Water Dam (RWD) were recently accessed by a registered engineer. The findings of the assessment indicate that the design capacity of the designs are sufficient however, these are heavily silted and need to be cleared out and reinstated to the original capacities (Davel, 2017).

UITKOMST COLLIERY: IWWMP
2.5.2 Klipspruit Mine
The Klipspruit Mine was historically mined, but no infrastructure other than the remnants of an old Pollution Control Dam (PCD) and an Eskom sub-station remain on site.
It is anticipated that the Klipspruit reserves will be accessed via two adits, Adit 2 and Adit 3. See Plan 2 for the position of these in relation to the mining right and underground areas. The position of Adit 3 has been approximated and will be finalised in future on completion of the necessary feasibility studies; as such the mining and operations of Klipspruit Mine will be approached in two phases.
Phase I: Adit 2
It is anticipated that the coal from Adit 2 will be trucked to the South Mine (Uitkomst Adit 1) for processing, using the existing road system. Thus, it is expected that the infrastructure at Adit 2 will be limited to that associated with underground mining only (i.e. no processing) and comprising a total of 21Ha. The following infrastructure is currently envisaged:
Access road; Mini substation and overhead lines, including a line running from Adit 2 to Adit1 (see Plan 2); Box cut and adit; Soils and spoils stockpiles; Run of mine stockpiles; Clean and dirty water management facilities; Security, access control and weighbridge; Offices, workshops and contractors laydown area; Change houses, lamp room, laundry and ablution facilities; Scrap yard and waste storage area; and Fuel and oil storage area. Adit 2 and the associated infrastructure will be located within the area previously disturbed and rehabilitated by Kangra Coal (Pty) Ltd, as such it is envisaged that the existing, old PCD can be refurbished for utilisation (see Figure 3).
Phase II: Adit 3
Once the position of Adit 3 is finalised, it is likely that a full scale wash plant and associated infrastructure (MRDS) will be required at the Klipspruit Mine.
Note: Phase II has been excluded from the scope of this IWUL Amendment. A separate water use license will need to be applied for once the position of Adit 3 and associated infrastructure is finalised.

3. REGULATORY WATER & WASTE MANAGEMENT FRAMEWORK
3.1 SUMMARY OF ALL WATER USES
The NWA regulates water use within South Africa. In terms of Chapter 4 and Section 22 of the NWA a person may only use water –
Without a license if that water use is permissible in under Schedule 1; is a continuation of an existing lawful use; or if it falls under the ambit of a General Authorisation. If the water use is licensed under the NWA. If the responsible authority has dispensed with a license requirement under subsection (3) of the NWA. Uitkomst Colliery has an approved water use license for certain existing uses on site. See attached, APPENDIX 3 for a copy of the approved license. Changes to the current and future water uses have however since been identified for the operation and as such this IWUL Amendment and IWWMP has been compiled.
The table below summarises all the current and proposed water uses for the operations, and highlights those which require amendments and/or licensing where relevant.

3.2 EXISTING LAWFUL WATER USES
According to the NWA, an existing lawful water use is defined as follows:
“32.(1) An existing lawful water use means a water use – (a) Which has taken place at any time during a period of two years immediately before the date of commencement of this Act; or (b) Which has been declared an existing lawful water use under section 33, and which – (i) Was authorised by or under any law which was in force immediately before the date of commencement of this Act; (ii) Is identified as a stream flow reduction activity in section 36(1); or (iii) Is identified as a controlled activity in section 37(1). (2) In the case of – (a) A stream flow reduction activity declared under section 36(1); or (b) A controlled activity declared under section 38, existing lawful water use means a water use which has taken place at any time during a period of two years immediately before the date of the declaration”. The old PCD located at the Klipspruit Adit 2 area is an existing dam, constructed within a non-perennial water course. As this water use(s) was in existence prior to 1998, it must be considered as an existing lawful water use.

3.7 WASTE MANAGEMENT ACTIVITIES (NEM:WA) & AUTHORISATIONS
The National Environmental Management: Waste Act (No. 59 of 2008) (NEM:WA) came into operation on the 1 July 2009. It addresses waste generation, classification and management issues, including recycling of waste.
No waste management licenses in terms of NEM:WA have been applied for or granted to date.
General, industrial and hazardous waste is and will be disposed of at licensed facility and no landfill facilities have or will be constructed on site. The storage of waste must comply with the relevant requirements or standards determined by the Norms and Standards for the Storage of Waste (Government Gazette 37088, 2013). The construction of the MRDS was prior to the amendment of the NEM:WA for the inclusion of mine residue, and as such is deemed to be authorized in terms of NEM:WA (refer to the transitional arrangements under the EIA Regulations GN. 982 of 4 December 2014).

4.2 SURFACE WATER (Letsolo, 2016)
4.2.1 Water Management Area (WMA 7)
The study area falls within WMA 7 – Thukela. The Thukela WMA lies predominantly in the KwaZulu-Natal province. It is a funnel-shaped catchment, with several tributaries draining from the Drakensberg escarpment towards the Indian Ocean. It is characterised by mountain streams in the upper reaches, where several parks and conservation areas are located, as well as a number of important wetlands and vleis. Rainfall is highest near the mountains and along the coast, and the mean annual precipitation is in the range from 600 mm to 1 500 mm.
Because of the high mean annual runoff and favourable topography, the Thukela basin offers some of the best opportunities for water resources development in South Africa.
4.2.2 Mean Annual Runoff (MAR)
Five (5) site specific catchments were delineated in order to provide site specific storm water management measures (see Plan 4). The delineated catchment areas are summarised as follows:
Table 9: Delineated Catchments
Description Surface Area Hydraulic Change in Significant Water Resource (km2) Length (m) height (m)

The MAR for the study area was sourced from the Water Research Commission database (WR2005). Table 10 provides activity based MAR for the 5 catchments in the study area.

Catchment 5 5.3 50.58 268074
4.2.3 Flood peaks & volumes
Flow through the rivers will be largely dependent on rainfall and therefore occur through summer months. Groundwater reserves from the mountainous areas and escarpment will feed hillslope seeps and may contribute to flow in the perennial streams into the dry winter months. During droughts the systems will remain dry.
The flood calculation outputs are summarized in Table 11 for each of the catchments relevant to the study area.

4.2.4 Surface Water Quality
The water quality has been discussed in terms of the baseline data for Klipspruit Mine obtained during the recent assessment conducted by Letsolo and the existing water quality monitoring programme at South Mine (Uitkomst Adit).
Klipspruit Mine:
The Doringspruit is the most significant receiving water body for Klipspruit Mine. The stream was dry during the survey conducted by Letsolo in November 2015, largely due to the drought experienced in South Africa. Therefore no samples could be taken along the stream at points MP A to MP C. A sample was obtained downstream at point MP F, although flow was very low (see Plan 5: Baseline Monitoring Points: Klipspruit Mine).
Samples were also taken at upstream and downstream dams along the Doringspruit, including Dam A, Dam B and Old Mine Catchment Dam. The water quality data obtained for the November 2015 sampling is presented in Table 12.
Dam A, upstream of the proposed site, showed good quality water for parameters tested and no values exceeded DWS or SANS drinking water quality standards.
Dam B, immediately downstream of the proposed Klipspruit Mine, the Old Mine Catchment Dam, which is downstream of Dam B and MP F which is the southernmost sampling point in the Doringspruit all indicated generally good quality water, however Iron exceed DWS drinking water quality standards; however the Iron levels at all three sites were still within SANS drinking water quality standards. The small variation in Iron concentration between Dam A (0.072mg/l), Dam B (0.116mg/l), the Old Mine Catchment Dam (1.14mg/l) and MP F (0.242mg/l) and the stability of Sulphate concentrations and pH between the upstream and downstream sites suggests that the elevated Iron levels are due to the geological nature of the area rather than an anthropogenic impact.
The recorded Iron levels are not expected to cause any health effects and the Doringspruit water quality can be said to be good based on findings from the first sampling.

South Mine: Uitkomst Adit
Surface water monitoring is currently being undertaken as per the requirements of the approved water use license on a monthly basis. Plan 6 indicates the position of the monitoring points whilst the section below summarises the results for the period September 2016 – March 2017. Please refer to APPENDIX 5 for a copy of the latest water monitoring report for the full results.
All the surface water samples, besides the two Farm Dams and the two river samples (Upstream and Downstream), fall within the dirty water footprint of the Uitkomst Adit and infrastructure area. These dirty water dams are exposed to water that has come into contact with coal and carbonaceous shales and are expected to be polluted. These dirty water management facilities have Conductivity levels, Sodium, Sulphate, Magnesium and Calcium concentrations that exceed the SANS 241 Drinking Water Standards.
The approved water use license for the Colliery imparts water quality limits for the PCD. These limits are so stringent that the up gradient unpolluted water samples do not comply. It must be stressed that the chemical results obtained are as expected for polluted coal water contained in a PCD. It is therefore unrealistic to place water quality limits on a PCD with the purpose of storing dirty water (as required by GN704).
Farm Dam 1 is an up gradient water sample and is not being impacted on by the coal mining activities at the adjacent Uitkomst Colliery. The Sodium and Sulphate concentrations for the month of February were 6.67 and 13.5mg/l, both an improvement when compared to the November sample results. The water, however, not being impacted on by the mining operations contains elevated heavy metals such as Aluminium and Iron. This results in the water being unsuitable for human consumption.
Upstream sampling point is located along the Kweekspruit, up gradient of the plant area. Only the Sulphate concentration exceeded the stringent RQO limit of 7.24mg/l with a concentration of 13.3mg/l in February. This sampling point is not being impacted on by the mining activities.
Downstream sampling point is located along the Kweekspruit, down gradient of the plant area. Water quality, similarly to Upstream does not comply with the RQO limits. Whilst the water is considered of good quality, the water quality in Downstream has marginally deteriorated when compared to Upstream. The February Conductivity level, for example, for the Upstream was 16.6mS/m compared to 24.2 mS/m at Downstream.
Of concern, however, is water sample Farm Dam 2. This is a clean water dam, situated down gradient of the RWDs and MRDS. During the month of September the Sulphate and Sodium concentrations were1067 and 290mg/l. During November these two parameters decreased to 360mg/l and 97.2mg/l. During the second quarter sampling event (January and February), the Sulphate and Sodium concentrations again increased to 851 and 184 mg/l. These results indicated that the down gradient water system is being impacted on by the Colliery’s activities possibly through seepage or poor surface water management. During the month of February the Colliery received over 108mm of rain in short succession. This resulted in the RWD overflowing into Farm Dam 2, hence the elevated concentrations of parameters seen in February. This spill was reported to DWS on the 23rd of February 2017.

4.2.5 Resource Class & River Health
The site is discussed in terms of aquatic sensitivity based on national programmes such as FEPA rivers and wetlands, as well as provincial programmes such aquatic biodiversity and land use decision support (LUDS) plans. This information was obtained from SANBI which has been appointed to manage South Africa’s biodiversity in terms of the National Environmental Management: Biodiversity Act. Furthermore, the biomonitoring results for 2016 (Iggdrasil, 2016) have been included and summarised below.
FEPA wetlands (Figure 6) are scattered throughout the project area. These have been assessed as part of the wetland assessment which is detailed later in the IWWMP. In general, the proposed infrastructure associated with Klipspruit Adit 2 has been planned so as to avoid wetlands and their 100m buffer zones as far as possible. According to NFEPA data, the Doringspruit is classified as a D, the Kweekspruit is classified as a C, the Wasbankspruit is classified as a C and the Slang River situated to the north of the study area is classified as a B (Iggdrasil, 2016). The Slang River drains the northern extent of the mineral boundary, where no surface or underground activities are proposed. This system will be unaffected by mining.
The bulk of the area falls within an upstream catchment management area for fish (Figure 7), however the north eastern portion of the study area is categorised as a FEPA due to the presence of sensitive wetland systems as well as river ecosystems and fish species (Iggdrasil, 2016). This area will remain unaffected by surface infrastructure or underground mining.
According to KZN aquatic biodiversity conservation areas (Figure 8) the mineral boundary is split into areas available for development (north) and areas earmarked for conservation (south). Earmarked areas are prioritised for conservation planning and land use management and will be further assessed in the next 5 years for potential biodiversity
39 | P a g e
UITKOMST COLLIERY: IWWMP management. No conservation areas occur within the mineral boundary. The existing Uitkomst Adit and underground mine areas falls within an area earmarked for conservation.
The Sub Quaternary Reach (SQR) of the Slang River (V31A-02319) indicated that the SQR is regarded as largely natural has a high ecological importance and a very high ecological sensitivity (Iggdrasil, 2016). This system will be unaffected by mining.
The SQR of the Doringspruit (V31D-02387) indicated that the SQR is regarded as largely modified has a moderate ecological importance and a high ecological sensitivity (Iggdrasil, 2016). This is the main receiving water body for the proposed Klipspruit Mine.
The SQR Kweekspruit (V32B-02414) was moderately modified had a high ecological importance and a very high ecological sensitivity (Iggdrasil, 2016). This is the main receiving water body for the proposed Uitkomst Mine.
From an overall aquatic perspective the receiving water bodies on site can be considered as moderately modified but of moderate to high conservation value.

Aquatic biomonitoring was completed by Iggdrasil during the high and low flow seasons of 2016. However as South Africa was experiencing a severe drought not all sites visited had enough water to complete adequate assessments.
Plan 7 indicates the sites visited during the surveys and Table 13 and 14 summarise the biomonitoring findings. Some correlation was observed with regional data in the sense that the Slang River system indicated highest ecological class. The remaining systems varied between modified to seriously modified ratings for various ecological class ratings, indicating that the systems are more modified than regional data presents.

4.2.6 Receiving Water Quality Objectives & Reserve
The following has been extracted from the DWAF report (2004) on water availability in the Thukela Water Management Area. The Buffalo River includes the towns of Dundee, Newcastle, Dannhauser, Utrecht and Madadeni. The main storage dams in the Buffalo catchment are:
Ntshingwayo Dam (previously known as Chelmsford Dam) which has a capacity of 199 million m3. The dam was built to supply water to the town of Newcastle, Eskom’s thermal power station and irrigation farmers downstream. Releases are sometimes made to dilute factory spillages that end up in the river system. Zaaihoek Dam, which was has capacity of 193 million m3. Zaaihoek Dam is on the Slang River, a tributary of the Buffalo River, and is used to transfer water to the Vaal system and the Majuba Power Station. Zaaihoek Dam can also supply downstream requirements by releasing water into the Slang River.
The MAR of the Buffalo Key Area is 884 million m3/a. The gross available surface water in the Buffalo River based on current development levels is estimated at between 173 million m3/a and 205 million m3/a depending on where in the catchment the water is utilised. Most of this yield is derived from dams discussed above. The occasional surplus in the Zaaihoek Dam was not made available in water quantity calculations.

There are significant return flows from irrigation, the urban and commercial centres as well as the mining and industrial activities in the catchment; the return-flow volumes being similar to that of the requirements of the ecological Reserve.
Irrigation is the dominant water use. The urban, rural and mining/industrial requirements are also significant, largely due to the development in and around Newcastle.
There is surplus water available in the Buffalo River Key Area that can be allocated without affecting the reserve allocation. Priority must be given to redressing of inequities and poverty eradication. Allocations must however be dealt with cautiously and the location of the surplus identified before making allocations. New allocations should not be made upstream of the Zaaihoek or Ntshingwayo dams unless accompanied by the provision of additional yield through the construction of farm dams.
The upper Buffalo River is the most severely impacted from a water quality perspective within the Thukela WMA. Acid mine drainage from numerous old coal mines and industrial pollution from the Newcastle area and the Ngagane River area, requires special intervention. Water quality in the length of the Buffalo River has been described by the Regional Office as being very poor.
It appears that RQO’s for the catchment have not been specifically set. The mine-related contamination is however dealt with in this IWWMP as this would be relevant to the development and includes:
Addressing impacts associated with mining-related impacts, specifically decant water and AMD formation. Addressing salt- and contaminant-loading into the Buffalo River Catchment.
4.2.7 Surface water User Survey
Water requirements in the Buffalo River Key Area are largely for irrigation followed by urban, mining/industrial and rural requirements. The area has a total demand of approximately 96m3/a, around 55m3/a is released from the catchment and availability in the catchment is estimated at 206m3/a. The catchment has a surplus of 55m3/a (DWAF, 2004). It must be stressed that the reserve has not specifically been included within the DWAF (2004) report.
Groundwater is the primary water source. Surface water use around the mine on the mine portions is primarily from springs that occur in the area and farm dams fed in part by springs
48 | P a g e
UITKOMST COLLIERY: IWWMP and rainfall. This water is used for domestic purposes as well as agricultural use in stock watering
4.3 SENSITIVE AREAS SURVEY
The overall mining right area is largely natural to semi-natural vegetation used for grazing purposes. Smaller portions have been transformed for crops or specific grazing lands, possibly for milk-cows. It has been found that most of the tracts of lower-lying grasslands are ‘managed’, i.e. regularly burnt and possibly ploughed to some degree in the past, and species assemblages vary according to management actions. Most of the region around the Klipspruit Adit 2 is at best semi-natural, where old mining activities have been abolished and the area revegetated.
An established road system exists to the Uitkomst and Klipspruit Adits off the R34 between Newcastle and Utrecht. Several Eskom lines traverse the study area, with a substation close to the planned new Klipspruit Adit. As mentioned above, the Uitkomst Adit 1 is fully operational, with pollution control dams, ore stockpile area, mine residue disposal sites and all related mine infrastructure.
No formally protected areas occur on site, although large areas have been incorporated into the National Protected Expansion Areas.
No other threatened ecosystems occur on site.
The vegetation types on and in close proximity of the study area as described in Mucina and Rutherford (2006) are the KwaZulu Natal Highland Thornveld (Gs6); the Wakkerstroom Montane Grassland (Gs7); and the Income Sandy Grassland (Gm14) (Dimela, 2016). None of the vegetation units are listed as threatened.
According to Mucina and Rutherford (2006), the KwaZulu Natal Highland Thornveld vegetation type is relevant to the main infrastructure areas and underground mining areas. Contrary to this, when comparing species assemblages on the ground, the largest part of the study area appears to be covered with Wakkerstroom Montane Grassland, especially the central plateau and boulder ridges, or it is at least a very strong transition to this vegetation type. Its landscapes is comprised of low mountains and undulating plains, covered mostly by short montane grasslands (Dimela, 2016).
The EKZN Wildlife Minset database shows that portions of the mining right area are classified as Critical Biodiversity Areas (Figure 9) (EKZNW 2010). Note that the Adit and infrastructure areas do not fall within any of these areas. CBA1 priority areas are associated with the northern extent of the mineral area where no surface or underground activities are proposed. Portions of the southern half of the properties overlay areas that are classified as ‘Critical Biodiversity Priority Area (Type 3 Optimal).
This new infrastructure will be close to the western extent of the historical Klipspruit mine workings, and placed on either secondary vegetation or habitats of relatively low species diversity and accordingly low sensitivity (see (Dimela, 2017).

The mining right area falls within the extreme southern portion of the Grasslands IBA (IBA No SA020) (Figure 9). The IBA extends from Newcastle and Utrecht in the south to Amersfoort in the north. It is considered a very valuable IBA and supports bird populations that meet all three categories, and is most notable for holding particularly important populations of several highly threatened species. However, the areas and species of most importance mostly occur away from the study site, particularly around the towns of Wakkerstroom, Memel and Volksrust (Marnewick et al 2015, Taylor et al 2015). Nevertheless, a number of sensitive species do occur and are likely to occur within the mining right area. Three Red Data species, White-bellied Korhaan, Southern Bald Ibis and Blue Crane were recorded on site during the 2016 survey and are likely to be regular within the mining right area (Harvey, 2017).
Figure 10: Mining Right Area in relation to Important Bird Areas (Harvey, 2017)
The mining right area is characterised by many wetlands including five hydrogeomorphic (HGM) units, namely: hillslopes seeps, hillslope seeps linked to stream channel, valley bottom without channel, valley bottom with channel and pan wetlands. Please refer to the Wetland/Riparian Assessment Report for full details (Hydro Pedo, 2017; APPENDIX 6). The wetland systems within the overall mining right are were categorised according to their HGM state(s) as well as being significantly disturbed or not. Thus, 10 grouped wetland systems were identified (Table 16).
52 | P a g e
UITKOMST COLLIERY: IWWMP
Due to surrounding land uses and activities including construction of roads, abstraction of surface and borehole water, farming of livestock, agricultural activities and mining, many of these wetlands have been greatly impacted upon and are in a disturbed state. According to the assessment, “the geomorphology of these wetlands is mostly intact, while the vegetation component is the most modified. The absence of major infrastructure, large dams, and year-around irrigation sustains the hydrological function of the wetlands in the study area. The vegetation is mostly affected due to the removal of natural communities through the establishment of dams, the presence of erosion channels and gullies, and agricultural activities within the wetland boundary.” (HydroPedo, 2017).

Furthermore, the overall Ecological Importance and Sensitivity (EIS) of the wetlands in the study area is regarded as B: High, which are wetlands that are considered to be ecologically important and sensitive, where the biodiversity of these wetlands may be sensitive to flow and habitat modifications and they play a role in moderating the quality and quantity of water of major rivers.

Only a proportion of the assessed wetlands will be affected by the proposed surface and underground activities (Plan 11). The wetlands affected by the two surface infrastructure areas and underground mine plan are summarised in the sub-sections below.
Underground Mine Areas:
The underground mine plan is overlain on surface by some wetlands, dominated by two channeled valley bottom systems that drain into the Doringspruit (Plan 11). The wetland system in the north-western area consists of a combination of wetland type G and H (Table 16), being undisturbed and disturbed channeled valley bottom wetlands with an overall combined PES of C/D – Moderately to Largely modified. The central wetland system is characterised as type H, being a disturbed channeled valley bottom wetland system, with an overall combined PES of E – Seriously modified (Hydro Pedo, 2017).
These wetlands are largely fed by surface water from seasonal rainfall and the base flow from the upper weathered aquifer, which ranges from 5 to 20 mbgl. The underground mining ranges from a minimum depth of 18mbgl to a maximum of 350mbgl. The mining is largely occurring deeper than 100m, which has no interaction with surface water reserves (Future Flow, 2017). These areas of the underground mining are thus not expected to interact directly with the surface and shallow sub-surface hydrogeological processes significantly (Future Flow, 2017).
However, the area where the mining is within 20 to 100mbgl has the potential to negatively affect the upper weather aquifer and the surface wetland systems. The shallowest area of the coal seam is associated with the adit and this is where the largest impact could be. The impact to the wetland could be related to dewatering during operations and negative impacts on water quality post-mining.
It is important to note that the leach test results do not show significant acid generating potential, which lowers the potential negative water quality impacts the underground mining could have on the surface water resources (Future Flow, 2017).

Adit & Infrastructure Areas:
The Uitkomst Adit and associated infrastructure was constructed in a non-perennial stream and hillslope seep (Plan 12). The disturbed hillslope seep has been determined to be a ‘Type C’ wetland as per Table 16. This wetland has been assessed to have a PES of F – Critically modified (Hydro Pedo, 2017). The wetlands feed into a valley bottom wetland downslope (east) and these systems are identified broadly as wetland Type H, being disturbed valley bottom wetlands with a channel. These wetlands have been assessed to have a mean PES of E – Seriously Modified (Hydro Pedo, 2017).
Plan 12: Uitkomst Adit 1 and affected wetlands as delineated by Hydro Pedo (2017)
The proposed Klipspruit Adit 2 is not planned to be constructed within any delineated wetlands. This area has already been disturbed by previous mining and has been assessed to no longer function naturally within the hydrological landscape (Hydro Pedo, 2017). This infers that there will be no significant direct impact to wetlands as this area is already impacted upon.
However, this area is within 100m of a valley bottom wetland and stream associated with the Doringspruit. This wetland system consists of a combination of wetland type G and H (Plan 12), being undisturbed and disturbed valley bottom wetlands with a channel respectively. The overall combined PES of this system has been determined to be C/D – Moderately to Largely modified.
The proposed route of the overhead powerline has avoided wetlands as far as possible as no pylons are placed in wetlands; however some pylons and cables will be within 100m of the identified wetlands.

4.4 GROUNDWATER (Future Flow, 2017)
The section below is extracted from the Geohydrological Study completed by Future Flow in 2016, revised in 2017. Please refer to APPENDIX 8 for a copy of the full report. 4.4.1 Aquifer Characterisation
Two aquifers occur in the area. These two aquifers are associated with a) the upper weathered material, and b) the underlying competent and fractured rock material.
Upper weathered material aquifer:
The upper aquifer forms due to the vertical infiltration of recharging rainfall through the weathered material being retarded by the lower permeability of the underlying competent rock material. Groundwater collecting above the weather / unweathered material contact migrates down gradient along the contact to lower lying areas.
Aquifer thickness data was available from the monitoring borehole drilling results. The recorded data shows that the upper aquifer has an average thickness of approximately 12 m, and can range between 5 and 20 m in thickness. These minimum and maximum values are not absolute values for the entire study area. Lesser thicknesses can occur from the competent hard rock outcropping in places throughout the high lying area.
It is considered that effectively between 1 and 3 % of the mean annual rainfall eventually reaches the groundwater table in the form of recharge to the aquifers (Grobbelaar, Usher,
58 | P a g e
UITKOMST COLLIERY: IWWMP
Cruywagen, de Necker, & Hodgson, 2004). Typical transmissivity values for this aquifer range between 0.1 and 2 m2/day.
The borehole yields in this aquifer are seasonally variable due to the strong dependence on rainfall recharge. Generally, it can be said that the yields of this aquifer during the rainy season can be around 1 to 3 L/s while sustainable yields will decrease markedly during the dry season. In some areas this aquifer will be laid completely dry during the dry season.
The groundwater quality in undisturbed areas is good due to the dynamic recharge from rainfall. This aquifer is, however, more likely to be affected by contaminant sources situated on surface.
Based on the combined effect of the relatively shallow nature of the weathered zone, where a number of areas have the competent rock outcropping on site, and the dependence on recharge from rainfall, it can be said that this aquifer is expected to show significant seasonal fluctuations.
Lower fractured rock aquifer:
Although the lower permeability of the unweathered rock material will retard vertical infiltration of groundwater, a percentage of the water in the upper aquifer will recharge the lower aquifer. Direct recharge from rainfall can occur where the fractured, competent rock outcrops. In areas where the stream bases of the non-perennial rivers are located directly on top of the competent rock the aquifer can be directly recharged from the surface stream.
The competent rock is subjected to fracturing associated with tectonic movements that took place during intrusion of dolerite dykes and sills into the older Karoo aged sandstone and shale sediments. Groundwater flows in the lower aquifer are associated with the secondary fracturing in the competent rock and as such will be along discrete pathways associated with the fractures. Faults and fractures in the sandstone and shale can be a significant source of groundwater depending on whether the fractures have been filled with secondary mineralisation.
The aquifers present in the area are classified as minor aquifer, but of high importance to the local landowners as it is their sole source of water for domestic and agricultural (stock watering and irrigation) purposes.
4.4.2 Hydrocensus
A hydrocensus was undertaken on the 2nd of February 2016 to identify and document groundwater users in the region. An additional two monitoring boreholes were drilled in the project area. In total 15 boreholes were located in the field.
The results of the hydrocensus are summarised in Table 17 and shown graphically Figure 11Figure 12. From this it can be seen that the depth to groundwater level ranges between artesian and 20.29 mbgl. Boreholes BH9 and BH10 were not accessible and the depth to groundwater level could not be measured. The depth to groundwater level at the point “Fountain” is assumed to be 0 m.
The water level measured in borehole “De Jager” appears to be anomalously deep compared to other boreholes in the area and is possibly due to the borehole being pumped shortly before the water level was measured. Borehole “Community” that is located close by
59 | P a g e
UITKOMST COLLIERY: IWWMP shows a water level of 7.50 mbgl which is in line with the other groundwater levels measured in the area.
In addition, the depth to groundwater level in borehole “BH11” is also anomalously low at 20.29 m. The reason for this is not known.
In areas where there are no large scale external impacts on the groundwater environment, such as the lowering of groundwater level through dewatering, and where the geology and aquifer interactions are not excessively complex it is expected that the groundwater level contours will reflect topographical contours, although at a moderated gradient.
Plotting groundwater level elevation versus topographical elevation for this project area yields a 99 % correlation as shown in Figure 12. This is a very high correlation between the groundwater level elevation and topographical elevation, however only nine groundwater levels which were obtained from the hydrocensus were used and there is limited information available in the study area. From this it is concluded that the groundwater levels generally mimic topography in the areas where the boreholes are located.

4.4.3 Potential Pollution Source Identification
Pollution Sources on Site:
The underground mine area, MRDS, overburden and topsoil stockpile areas, process water dams and settling dams act as potential sources of contamination to the aquifers. For the purpose of this discussion it is assumed that good housekeeping such as storage of potentially hazardous material will be within properly constructed and lined or paved areas. Oil traps will be sized, operated and maintained to contain all discarded oil from working areas etc.
Leach testing and the results can be used to determine the potential source concentrations. From the leach testing it can be seen that all the samples comply with the IFC effluent guidelines. Therefore, it was decided to apply a generic approach during the impact assessment modelling. The results can then be applied to any contaminants that may be identified.
A value of 100 is assigned to the pollution source areas; in this case the underground mine area, mine residue, overburden and topsoil stockpile areas, process water dams and settling dams. In effect this represents 100 % of the starting concentration of any contamination. The plume distribution then represents the percentage of starting concentration that will be measured at a specific point. For example should the plume at a specific point indicate a value of 50, it indicates that the element concentration at the point and time is expected to be 50 % of the initial source concentration.
4.4.4 Groundwater Model Results: Operational
Groundwater level drawdown:
The mine floor elevations are below the general groundwater level thus causing groundwater flows into the underground mining area from the surrounding aquifers during operations.
The 3D numerical groundwater flow model was used to simulate the development of the drawdown cone over time in the vicinity of the underground mine area. The provided mine plan that indicates a nine year life of mine for the operations was used.
Numerical modelling shows that during the life of operations the groundwater flow directions in the vicinity of the underground mine will be directed toward the mine area. This is due to mine dewatering causing the groundwater levels to be drawn down to the mine floor elevations.
The maximum drawdown in the groundwater level from pre-mining levels in the upper weathered aquifer is negligible and calculated at less than 1 m. The maximum drawdown is calculated at 250 m for the lower fractured aquifers (Plan 15).
The direct impact of the mine dewatering on the fractured rock aquifer, within which the mining area is located, is greater than the impact on the weathered material aquifer which lies more than 100 metres above the underground workings and is to some extent disconnected from the impact of the mine dewatering by the semi-impermeable sandstone
64 | P a g e
UITKOMST COLLIERY: IWWMP and shale that overlies the mining area and separates the mine from the weathered material aquifer.
The drawdown in groundwater level and the associated cone of depression will develop over time in the fractured rock aquifer as the mining progresses. In the fractured rock aquifer the zone of influence of the groundwater level drawdown extends up to 1 400 m west and 1 100 m north and south of the mining area.
The springs located on the plateau and the escarpment are dependent on the upper weathered aquifer which is reliant on recharge from rainfall. Based on the disconnect between the deeper lying underground mine, and the shallow aquifer that feed the springs that occur on the plateau and escarpment as described above, the impact from mine dewatering on the springs on the escarpment is calculated to be minimal (<1%) because mining occurs within the fractured rock aquifer which will experience the greatest impact. The exception will be around the Klipspruit access point (proposed Adit 2) which will be directly connected to the upper weathered aquifer. The zone of influence of the impact on the groundwater levels in the weathered material aquifer is expected to be less than 500 m in extent.
Plan 15 shows that six of the hydrocensus boreholes (BH8, Klip1, Klip2, Landman, Community and de Jager) will be impacted by the groundwater level drawdown in the area. The maximum drawdown in groundwater level in each of the boreholes during the life of operations is calculated at:
BH8: 40.7 m; Klip1: 37.1 m; Klip2: 3.7 m; Landman: 1.9 m; Community: 12.8 m and De Jager: 12.8 m. Three of these boreholes are monitoring boreholes and are not used by private landowners for water supply. Three of these boreholes (Landman, Community and de Jager) are privately owned and used for water supply purposes, however the boreholes are located in the weathered material aquifer which shows an extent of disconnect with the fractured rock aquifer where the underground workings and associated dewatering will take place.
Groundwater inflows into the underground mine
Groundwater inflows volumes into the mine area over 9 years were calculated using the 3-D numerical groundwater flow model. The obtained results are summarised in Table 18.
65 | P a g e
UITKOMST COLLIERY: IWWMP
Table 18: Groundwater inflow volumes into the underground mining area
Year Expected groundwater inflow volume (m3/day)
1 3 510
2 3 870
3 4 840
4 6 400
5 7 385
6 8 275
7 8 930
8 9 490
9 8 365
The groundwater inflow volumes into the underground mining area are expected to range between 3 510 and 9 490 m3/day. The groundwater inflow volumes decrease slightly during the final year of mining.
The high inflow volume is due to the mining area expanding into areas where the host geology is not dewatered yet and water is released from storage, thus keeping the inflow volumes relatively high. During the last year of life of mine less statured rock is broken and the inflows decrease.
The flow model only takes average yearly values such as average annual recharge from rainfall into consideration. Therefore, no seasonality is included in the calculations. However, it is not expected that the fractured rock aquifer will show significant seasonal changes.
Groundwater contamination:
The pollution source areas (underground mine area, mine residue, overburden and topsoil stockpile areas, process water dams and settling dams) are located on the western and south eastern perimeter of the existing Uitkomst Adit area outside the zone of influence of the groundwater level drawdown cone; therefore it can be expected that contamination will migrate away from these sources during the operational phase. Similarly, the overburden and RoM stockpile area at the proposed Adit 2 fall outside the groundwater level drawdown cone and contamination is expected to migrate away from these point sources.
It must be noted however that leach test results show that the leach qualities are expected to comply with the LCT0 quality guidelines. Therefore, it can be said that the impact on the groundwater quality of any seepage that originates from the mining area will not exceed water quality guideline requirements. This should be kept in mind when interpreting the pollution plumes shown in Plan 16 and Plan 17 as well as the discussion below.
66 | P a g e
UITKOMST COLLIERY: IWWMP
The contaminant plumes are calculated to migrate 400 m and 1 000 m down gradient from the western and south eastern areas respectively. The wetland and three monitoring boreholes (BH1, BH20 and New BH3) will be impacted by seepage migration away from the potential pollution sources.
Contaminant migration away from the overburden and RoM stockpiles at the Adit 2 are expected to migrate approximately 300 m down gradient. Contamination is expected to reach the Doringspruit west of Adit 2K.
During the operational life of mine the mining area will be dewatered. This will cause the groundwater flow directions around the mining area to be directed towards the mine. Due to this, little to no contamination is expected to migrate away from the mining area during the life of mine.
Contamination that does escape the mining area is expected to migrate downgradient slightly as shown in Plan 17. It is not expected that streams in the area will be impacted significantly (>1 %) based on the fact that:
The contaminant migration will be along the fractured rock aquifer with no direct discharge into the streams; and Leach test results show the leachate that forms in the underground mine is expected to be of relatively good quality and all elements comply with LCT0 quality guidelines.

4.4.5 Groundwater Model Results: Long Term Post Operations
Recovery of groundwater levels and decant potential:
In the post operational environment groundwater levels and flow patterns in the area will recover to near pre-operational levels. The time required for recovery of the groundwater levels to near pre-operational levels in the study area will be dependent on a number of factors:
There will be inflows into the underground mine from the surrounding aquifers. The inflow rate will depend to a large extent on the groundwater flow gradient between the groundwater level in the surrounding aquifers and the water level in the underground mine; and Recharge from rainfall into the underground mine has been shown to range around 1 % of the mean annual rainfall (Grobbelaar, Usher, Cruywagen, de Necker, & Hodgson, 2004). This will contribute to the flooding of the underground mine. The rate of rise of the water level in the underground mining area can be calculated:
As described above the inflows into the underground mine areas will depend on inflows from the surrounding aquifers. The mining area is measured to be approximately 8.61 km2 (8.61×106 m2). Using an average void space of 70 % of the underground mining area with the pillars in place, the mining area of 8.61×106 m2 and an average seam thickness of 1.5 m, it can be calculated that approximately 9 040 500 m3 of void space has to be filled.
Inflows from the surrounding aquifers were calculated to be between 3 510 and 9 490 m3/day. The inflows are partly controlled by the groundwater flow gradient with increasing flow associated with higher flow gradients. The inflows will reduce over time as the water level in the underground mine area rise and the flow gradient decreases due to the reduced vertical difference between the surrounding regional groundwater levels and the water level in the underground mine. For the purpose of this discussion an average of 6 000 m3/ day is used.
From the above it is calculated that recovery of the groundwater levels will take 1 506 days or approximately 4.1 years.
At no point is the coal seam floor elevation above that of the surface elevation at the mine entrance. Therefore, no decant is expected.
Contaminant migration:
The groundwater levels in the mining areas will recover due to the mine dewatering stopping. The recovering groundwater levels will lead to a re-establishment of groundwater flow patterns away from the mining area. This will allow for contaminant migration away from the mining area in a down gradient direction.
The expected contaminant plume at 50 and 100 years after closure is shown in Plan 18Plan 19 respectively. From this it can be seen that the contaminant plume development is expected to follow topography and migrate 1 000 m west toward the Dorpspruit and 2 000 m east towards the Kweekspruit.

Leach test results show that the leach qualities are expected to comply with the LCT0 quality guidelines. Therefore, it can be said that the impact on the groundwater quality of any seepage that originate from the mining area will not exceed water quality guideline requirements.

5.2.1 Process Water
Water will be recycled on site as far as possible and dirty water will be prioritized for process needs (use in the process plant or for use underground). The process plant uses approximately 3,250m3 of water / day.
Dirty Water Dams:
There are four existing dirty water dams at Uitkomst Adit/Adit 1 and one existing dam at the proposed Klipspruit Adit 2 area.
Plant Water Dam A & Plant water Dam B: Receives water from the RWD. Fines are settled out and water is then fed to the plant for processing. Uitkomst PCD: The PCD has been designed to contain runoff from the processing and infrastructure area during a 1:50 year flood event. PCD water will be pumped to the RWD for water balance maintenance. Recent investigations indicate that this dam is heavily silted and must be cleaned out to its original capacity. Uitkomst RWD: will contain all dirty water runoff from the MRDS facility, as well as supernatant water pumped from slurry penstocks and seepage from the slurry collected from the under drainage at the MRDS facility. May also receive water from the PCD for water balance maintenance. Recent investigations indicate that this dam is heavily silted and must be cleaned out to its original capacity. Water will be pumped from the RWD to the Plant Dams for use in the plant. Water will also be abstracted from this dam for dust suppression. Klipspruit PCD: It is proposed that the existing PCD (Plate 1) be upgraded. The PCD extension has been designed to cater for a 1:50 year flood event with a 0.80m freeboard (capacity of 5,000m3). The dam will receive runoff water from the Klipspruit dirty footprint area as well as water from the underground workings. This water will be used for dust suppression. Please refer to APPENDIX 10 for the applicable engineering drawings.
Dust Suppression:
Water for dust suppression will be sourced from the Uitkomst RWD and the Klipspruit PCD. Dust suppression. Water sourced from these dams for dust suppression will only be used within the dirty footprint of the mine, to prevent contamination of clean areas with dirty water.
For dust suppression over clean areas, water will be sourced from Farm Dam 1.

Coal Stockpiling:
RoM and product stockpiles exist at the Uitkomst Adit/Adit 1 area and have been licensed. The overall capacity has however since increased and must be amended (see Figure 14 below for the individual stockpiles areas and maximum storage capacity at the Adit 1 area). The cumulative, maximum coal storage capacity at Uitkomst Adit 1 is 103,510m3.
RoM coal from the Klipspruit underground will be temporarily stockpiled on surface at Adit 2 (maximum capacity estimated at 7,500m3) before being trucked to the existing Uitkomst plant area for processing.
All the coal stockpile areas will be compacted and made as impermeable as possible; and slightly sloped to drain water into the PCDs or sump.

Mine Residue Disposal Site (MRDS):
The existing MRDS is operated as a co-disposal facility i.e. coarse discard at the perimeter and slurry placed to the inside. The MRDS will in future need to be expanded up the mountain slope to meet the additional capacity requirements as such the MRDS has been re-designed (see APPENDIX 10).
The MRDS has under drainage to collect seepage from the slurry. Installation of sub surface drainage will also be required in the future expansion areas. This seepage collection system would be installed below the coarse discard section of the waste facility assisting with structural stability and environmental protection. This drain would consist of 2.0m wide fin drains, collection and outfall pipes. All seepage would be collected at designate outfall locations in manholes. The manholes are linked with a 250 OD UPVC collection pipe. Seepage water will flow under gravity to the RWD.
The existing slurry compartments are equipped with a concrete intake tower slotted to one side, to allow for slurry and water level control. Normal operation requires the placement of planks in the slot to control water decant. This method allows for the settlement of solids and decanting of water only, if correctly implemented. It is however proposed that the slurry placement be in such a way that the low point is always at the penstock intake. This can be achieved with the extension of the slurry delivery system to the inside perimeter of the discard facility (Davel, 2017).
Discard placement must be completed systematically in layers and along the wall, providing in order to provide for the necessary freeboard in the slurry pond. Continuous compaction of the discard must be undertaken to prevent spontaneous combustion.
The cut off trench is designed to collect runoff from the co-disposal facility and drains to the RWD.

5.2.2 Storm Water
In general storm water management and drainage infrastructure onsite accommodates a 1:50 year storm event as required by legislation. Clean and dirty water will be separated and dirty water channeled into dirty water containment facilities. Clean water will be diverted around various dirty footprints by means of channels and berms to the natural environment. Please refer to APPENDIX 10 for the engineering designs specifying the dimensions and location of the storm water drains.

5.2.3 Groundwater
Dewatering activities will be carried out on site to allow for the safe continuation of mining. Electric pumps will be utilised to dewater the underground workings, and dispose of mine affected water into the boxcut sump prior for re-use. Water will be recycled as follows:
Water will be pumped to the underground for any necessary water requirements associated with underground dust suppression and drilling. Excess water will be stored underground within mined out sections. Water will be pumped to the mine dams for plant make-up water or dust suppression where required. During the operational phase the maximum drawdown in the groundwater level from pre- mining levels in the upper weathered aquifer is negligible and calculated at less than 1 m. The maximum drawdown is calculated at 250 m for the lower fractured aquifers.
The direct impact of the mine dewatering on the fractured rock aquifer, within which the mining area is located, is greater than the impact on the weathered material aquifer which lies more than 100 metres above the underground workings and is to some extent disconnected from the impact of the mine dewatering by the semi-impermeable sandstone and shale that overlies the mining area and separates the mine from the weathered material aquifer.
The drawdown in groundwater level and the associated cone of depression will develop over time in the fractured rock aquifer as the mining progresses. The zone of influence of the groundwater level drawdown extends up to 1 400 m west and 1 100 m north and south of the mining area (Future Flow, 2017).
5.2.4 Potable & Domestic Water Supply
Water for potable and domestic use is sourced from two boreholes (1 at Klipspruit and 1 at Uitkomst), as well as the nearby Farm Dam.
At Uitkomst Adit 1: water is pumped to two prefabricated reservoir tanks (each with a capacity of 250m3 - see Plate 2). From here it is circulated to a number of Jojo tanks for use within the change house, offices, ablutions and laundry. At Klipspruit Adit 2: water will be pumped from the borehole to Jojo tanks for use within the change house, offices, ablutions and laundry.

5.2.5 Water Balance
Currently the mine is water deficient. However the groundwater model predicts that as mining progresses underground, an inflow of between 3 510 and 9 490 m3/day is expected, and thus in the long run a surplus expected. Excess water will remain underground and pumped into mined out compartments / workings. The table below summarises the expected water balance for the operations.

5.9.3 Biomonitoring
Biomonitoring is currently undertaken as per the requirements of the approved water use license. With the inclusion of the Klipspruit reserves it is recommended that the biomonitoring programme be updated as follows:
Plan 22: Proposed biomonitoring points (KLB3 and KLB4 may be excluded if sites are not appropriate for biomonitoring and may be replaced with other sites)
Note: Sites KLB3 and KLB4 must be revisited to determine their appropriateness to include in the overall biomonitoring programme.
The following stressor, habitat and response indicators will be evaluated and will be included in the biomonitoring report:
In situ water quality assessment and determination of water quality variables of concern, where available. Identification of prevailing existing impacts. Habitat assessment, utilizing the Invertebrate Habitat Assessment Systems (IHAS). Macro invertebrate assessment, including the generation of reference conditions and determination of Present Ecological State utilizing the South African Scoring System Version 5 (SASS5) and the Macro-Invertebrate Response Assessment Index (MIRAI). Diatom assessment at sites KLB2, KLB6 and KLB7.

5.9.4 Waste Monitoring
The dirty water dams and associated dirty water management features must be regularly (weekly) inspected to ensure these are functioning optimally. Signs of erosion, spillages, and leaks will be investigated and repaired if observed. The capacities and freeboard will be maintained in all dams. Silt build-up and any obstructions will be cleared from dams, silt traps and diversion channels/trenches. Deposition cleared from dirty water infrastructure will be disposed of onto the MRDS. The Mine Manager and SHEQ Manager will inspect the MRDS facility at least weekly to ensure activities are being undertaken in line with standard operating procedures and engineered designs and plans. The SHEQ Manager will inspect the conservancy tank areas and portable toilet facilities at least weekly to ensure that no sewage leaks / spills are occurring and ensure sites are clean. The SHEQ Manager will also ensure that these are emptied / serviced by a reputable contractor on a regular basis. Records of all sewage removal will be kept in a detailed waste manifest register and waste certificates will be obtained from the disposal contractor. The SHEQ Manager will inspect areas at least monthly for illegally dumped waste and will ensure domestic waste bins/skips are ideally placed and ensure that all contractors and staff collect waste and dispose of waste into these skips or bins. The SHEQ Manager will inspect the bunded areas and associated oil traps weekly and after rainfalls to ensure taps are closed, oil traps are not over-flowing and bunded areas are not flooded.
5.9.5 Supplementary Monitoring Systems
As sedimentation can result in impacts to surface water bodies and wetlands, soil management principals must be applied on site. Furthermore, some alien invasive species are known to have detrimental effects on water resources and stream characteristics. Therefore the following monitoring is recommended and considered part of water management.
Any rehabilitated areas, such as the sides of the MRDS facility, and soil stockpiles will be monitored for soil quality and depth on an annual basis and recommendations made by the specialist pedologist, including the fertilization requirements, will be implemented on site. Surface area of underground mining areas will be monitored for any potential subsidence which will be rehabilitated if noted. The site will be monitored for alien invasive species on a 6 monthly basis (more frequently for herbaceous species) and an ecologically sensitive alien invasive eradication programme will be implemented on site. Any rehabilitated areas and soil berms and stockpiles will be surveyed visually for erosion vegetation cover on a monthly basis and any areas of failed germination or poor vegetation cover will be re-assessed and re-seeded. Consideration will be given to hand planting of seedling plugs if germination continues to be low in an area. Erosion control measures, such as gabions, will be implemented on persistently eroded areas or where erosion is severe.

5.12 ASSESSMENT OF LEVEL OF CONFIDENCE OF INFORMATION
All specialist studies are conducted to certain levels of confidence, and in all instances known methodologies have been used and confidence levels are generally high. This means that in most cases the situation described in is accurate at high certainty levels, but there exists a low probability that some issues have not been identified during the studies. Such situations cannot be avoided simply due to the nature of field work and have therefore not been further discussed. Furthermore, statistical analyses and mathematical models are merely tools which assist the researcher in assessing field observations and have innate assumptions which can reduce objectivity of the results obtained. This is not seen as a major flaw but should always be considered when assessing results.
6. WATER & WASTE MANAGEMENT
6.1 WATER & WASTE MANAGEMENT PHILOSOPHY
Uitkomst Colliery’s philosophies can be summarised as follows:
The attitude towards the mine project as a whole will be to: o Primarily pre-empt impacts and prevent the realisation of these impacts - PREVENTION. o To ensure that activities which are expected to impact on the environment are undertaken and controlled in such a way so as to minimise their impacts – MODIFY and/or CONTROL. Specific strategies include: . To ensure systems are in place for immediate and adequate treatment and/or rectification of any significant impacts that may occur due to the proposed activity – REMEDY. . To ensure the operation and rehabilitation is commenced and conducted in such a way so as to have minimal impact on the water resources and ensure post closure objectives are considered right from the onset to ensure these are attained at closure. Additional philosophies relating to storm water management on site will be to: o Prevent unnecessary decreases to the downstream water quantity and quality. o Prevent the clean storm water runoff from upstream locations outside the activity footprint from entering the activity footprint. o Ensure that all dirty water within the footprint is contained within the area and no deliberate discharge of dirty water to the environment takes place. Additional philosophies relating to process water management on site will be to: o Ensure that all dirty water within the footprint is contained within the area to reduce ensure maximum containment of mine water to reduce the need for make-up water. o On-site water is recycled as far as possible and prevents water wastage. Additional philosophies relating to groundwater management on site will be to: o Prevent unnecessary water supply disruption to surrounding groundwater users. o Contain dirty groundwater that develops due to mining activities.
112 | P a g e
UITKOMST COLLIERY: IWWMP
o Contain and/or treat any potential plume or decant that may arise after mining. Additional philosophies relating to waste and hazardous material management on site will be to: o Conduct hazardous material handling and storage in an environmentally conscious manner at all times on site. o Ensure a cradle-to-grave philosophy regarding any waste generated on site. o Create awareness of the creation, reuse and final disposal of waste and ensure all is conducted in an environmentally responsible manner. 6.2 STRATEGIES
Strategies that will be employed to ensure the above philosophies can be attained are discussed below. General strategies include:
Prevent, modify, remedy, control and/or stop any action, activity or process which causes pollution or environmental degradation. Prevent, contain and/or remedy the cause of pollution or degradation and migration of pollutants. Comply with any prescribed legislation, management standards and/or practices. Ensure responsible, thoughtful and well planned execution of activities on site. Ensure that formal response procedures are in place for various potential environmental emergencies. Good house-keeping practices. Contain dirty water on site, and limit the dirty footprint to as small an area as possible. Ensuring the storm water management plan is implemented on site prior to new activities taking place on site. Recycling water on site as far as possible on site. Recording water abstraction and dewatering and recycling water on site in order to reduce the need for abstraction of water from clean water resources for make-up water. Disposing of waste responsibly. Storing waste on site responsibly and for as short a duration as possible. Recycling waste as far as possible. Ensuring all contractors dispose of waste responsibly and that all certification for disposal of waste from the proposed mine is in obtained from the contractors. Establish and maintain a waste manifest. Implementing an adequate monitoring programme and schedule as detailed in this IWWMP to: o Ensure that mitigation and management measure are effective. o Allow quick detection of potential impacts/risks, which in turn will allow for quick response to issue/impacts. o Allow quick implementation of proposed action plans as set out in this IWWMP. o Reduce duration of any potential negative impacts. Ensuring quick access to necessary specialists to assist with any environmental issues to ensure the best possible action can be taken speedily. Ensure post closure objectives are considered right from the onset and throughout operations to ensure these are attained at closure.
113 | P a g e
UITKOMST COLLIERY: IWWMP
Ensure strategies are in place to compensate for any water losses to registered water users. 6.3 PERFORMANCE OBJECTIVES & GOALS
6.3.1 Environmental Objectives and Goals
Environmental objectives are:
Protect the biophysical environment as far as possible o Minimise impacts to the biophysical environment. o Ensure relevant legislation in terms of NEMA and Conservation of Agricultural Resources Act are applied on site including but not limited to alien invasive management and protection of ecologically sensitive species and environments. Protect the water resources in the area. o Ensure clean and dirty water separation systems are established on site from the onset. o Use water responsibly and recycle water as much as possible. o Ensure relevant legislation regarding the NWA are applied on site. Ensure atmospheric pollution is to a minimum: o Manage dust generation. o Ensure all pollutants are within levels stipulated in the National Air Quality Act. o Complete the NAEIS registration and continue annual reporting to the site as required. Ensure an adequate rehabilitation plan is followed to allow for adequate rehabilitation to a prescribed land use which will be grazing. 6.3.2 Closure Objectives
The overall closure objectives are:
To ensure that all impacts incurred during the operational phase are mitigated and that these are reduced over time, and that these mitigation measures are in line with best practices (existing at the time); To minimise the impacts on the local community; To ensure that as little poor quality water as possible decants from the mining areas; To rehabilitate the areas as soon as possible; To return the land to that of at least the pre-mining use which will be grazing land capability; To ensure that residual impacts after closure of the mine are minimal; and Apply for a closure certificate.
6.4 MEASURES TO ACHIEVE & SUSTAIN PERFORMANCE OBJECTIVES
Measures to achieve and sustain the abovementioned objectives are listed in Table 22 below, along with the responsible persons and timeframes for implementation.

6.5 OPTION ANALYSES & MOTIVATION FOR IMPLEMENTATION OF PREFERRED OPTIONS
Uitkomst Colliery is an operational mine, as such alternatives were not considered.
6.6 IWWMP ACTION PLAN
The management strategy and monitoring plan in the IWWMP has been devised for each phase of mining. Where necessary some measures must continue on into the next phase. Also indicated in the monitoring and action plan is the frequency at which monitoring/inspection is to be conducted, and the person/individual responsible for ensuring these monitoring/inspection activities are properly carried out (either carry these out personally or delegate to another individual who will report back to the responsible person). Therefore the above management strategy and monitoring plan already addresses the short-term, medium-term and long-term actions that will need to be considered in the form of a management plan for the construction and upgrade phase (immediate to short-term action), operations (short to medium-term actions that must be implemented over the next 1-2 years), decommissioning and post closure (long-term actions) phases of mining. A very brief summary is provided below.
Immediate to Short-Term Actions:
Immediate actions necessary are related to environmental authorisations and other authorisations related to the mining activities. Regarding the environmental authorisations the following will be necessary:
Ensure IWUL is amended/granted by DWS. Ensure all the monitoring programmes are implemented immediately and conducted at stipulated frequencies for the life of mine. Ensure all activities comply with GN704 unless relevant exemptions are granted by DWS. Ensure the management measures and performance assessment is applied as per this document. Ensure the monitoring programme as indicated in this document is applied.
Short-Term Actions:
Ensure the relevant EMPr and IWUL audits are scheduled and carried out and submitted to the authorities. Ensure the management measures and performance assessment is applied as per this document. Ensure the monitoring programme as indicated in this document is applied.
Medium-Term Actions:
Ensure the management measures and performance assessment is applied as per this document. Ensure the monitoring programme as indicated in this document is applied. Ensure the relevant compliance audits are carried out and submitted to the authorities.
116 | P a g e
UITKOMST COLLIERY: IWWMP
Ensure that the preferred option for decant management is largely drafted. Ensure the final rehabilitation plan is drafted.
Long-Term Actions
Ensure the management measures and performance assessment is applied as per this document. Ensure the monitoring programme as indicated in this document is applied. Ensure the relevant compliance audits are carried out and submitted to the authorities. Ensure closure applications are finalized and submitted.
6.7 CONTROL & MONITORING
The monitoring and audit reports discussed below will all be integral to the compilation of the annually updated IWWMP, which will essentially be composed of this IWWMP with updates to reflect any changes in activities on site, address any new management strategies that need to be incorporated as indicated through monitoring and audit reports and generally allow for the IWWMP to become a living document which can be updated with new technologies and new alternative management measures and best practices.
In addition, inspection and monitoring logs will be kept on site in terms of the general monitoring and inspection requirements indicated in Table 6. These logs must be made available to auditors and therefore be kept on site.
6.8 MONITORING OF CHANGE IN BASELINE
The baseline information has been reported for groundwater, surface water and aquatic Biomonitoring within the various license applications. The monitoring plan as elaborated within this IWWMP as well as the various EMP reports will continue and be upgraded when necessary. Monitoring data will be compared to the baseline data.
6.9 AUDIT & REPORT ON PERFORMANCE MEASURES
The monitoring plan has been established to determine if the performance objectives are being met through the implementation of the management strategies. Water quality and bio-monitoring reports will be compiled annually for submission to DWS. These reports will relate findings and trends related to the latest monitoring data in relation to past monitoring findings. If monitoring activities suggest that issues on site exist, then these monitoring reports should further identify the source and make recommendations to update management strategies in order to rectify or reduce these impacts.
An internal audit should be carried out by the person responsible for the implementation of the IWWMP to ensure that the general monitoring and inspection activities as indicated in Table 6 are adhered to and that appropriate and immediate action is taken to address any issues observed. This general monitoring plan will also assist in ensuring that the environmental
117 | P a g e
UITKOMST COLLIERY: IWWMP performance objectives are attained and should therefore form part of the audit process on general performance.
6.10 AUDIT AND REPORT ON RELEVANT OF IWWMP ACTION PLAN
An annual audit will be compiled by a suitably qualified, external party on the conditions of the IWUL and should also include an audit of activities against GN704. The conditions proposed by DWS within the IWUL and the requirements of GN704 will be critical to attaining performance objectives.
The IWUL and GN704 audit will compare activities on site and determine the status of thereof. These should be identified as compliant or non-compliant, and recommendations made to rectify any non-compliance identified.
Further, the IWWMP and associated monitoring programmes should be reviewed annually and updated where relevant.
6.3.3 Other Performance Assessments
All information as required by the various Government Departments should be captured and be readily available for submission when required. Therefore all monitoring data, inspections, incidences and remedial actions taken must be recorded and logged and be at the disposal of authorities during site visits. A monitoring/inspection and action log will be maintained on site which will record date of inspection, any evidence of non-compliance observed with regard to the EMP and IWUL, all issues observed during inspections or through monitoring data, and all remediation actions taken. This log will be part of the public domain and be available to authorities during site visits. A complaints register will be maintained on site and operated in much the same as the incident log as discussed above. An annual performance assessment (different timeframe may be stipulated by authorities which will then be relevant) will be conducted by an external consultant throughout the life of mine as required by the NEMA. This is conducted to assess the adequacy and compliance of the EMP, and the relevant legislation. This report will comply with the format as set out in NEMA’s EIA regulations and will be submitted to the DMR. The Quantum of the Financial Provision will be reviewed on an annual basis, and submitted to the DMR. Table 27: Monitoring Plan
