EMPr: Midmar Crushers Expansion 41717 ENVIRONMENTAL MANAGEMENT PROGRAMME: PROPOSED EXPANSION OF THE MIDMAR CRUSHERS (PTY) LTD DOLERITE QUARRY SITE, UMNGENI LOCAL MUNICIPALITY, KWAZULU-NATAL 1. INTRODUCTION Terratest (Pty) Ltd has been appointed by Midmar Crushers (Pty) Ltd to undertake the environmental services required for the proposed amendment of the Midmar Crushers (Pty) Ltd Mining Right, uMngeni Local Municipality, KwaZulu-Natal. The amendment is in terms of Section 102 of the Mineral and Petroleum Resources Development Act (Act No. 28 of 2002), as amended and the Environmental Impact Assessment Regulations (2014), as amended. The existing Mining Right1 which Midmar Crushers (Pty) Ltd holds is for dolerite and the proposed amendment of the Mining Right includes for the extension of the Mining Right Area and development of an additional dolerite quarry pit within the extended Mining Right Area. The proposed development requires Environmental Authorisation from the Department of Mineral Resources (DMR) prior to construction commencing. The amendment proposal includes for the westward extension of the existing Midmar Crushers (Pty) Ltd Mining Right Area. The extension of the current Mining Right Area will be limited to approximately 19.4ha and will include for the construction of a new access road, dolerite quarry pit, stockpiles, ablution facilities and site offices. Post construction, two operational dolerite quarries will be available for Midmar Crushers (Pty) Ltd to utilise (i.e. the existing quarry located in the current Mining Right Area and the proposed new quarry in the extension area) until such time as the existing quarry pit is rehabilitated. However, in order to limit the cumulative impacts of operation, only one quarry will be utilised at any one time. As a result, blasting and associated quarrying activities will only occur within one quarry pit at a time and not simultaneously. This EMPr has been compiled in accordance to Government Notice (GNR) 982, Appendix 4 of the Environmental Impact Assessment (EIA) Regulations (2014, as amended). In this regard, the EMPr provides mitigation measures for impacts identified in the Basic Assessment (BA) Report by defining the relevant objectives, outcomes and actions. In accordance with the Integrated Environmental Management Guidelines published by the Department of Environmental Affairs & Tourism (DEAT) in 1992, the purpose of an EMPr is “to describe how negative environmental impacts will be managed, rehabilitated or monitored and how positive impacts will be maximised”. Section 28 of NEMA (National Environmental Management Act, Act 107 of 1998) which pertains to “Duty of care and remediation of Environmental Damage” states that: "(1) Every person who causes, has caused or may cause significant pollution or degradation of the environment, must take reasonable measures to prevent such pollution or degradation from occurring, continuing or recurring, or, in so far as such harm to the environment is authorised by law or cannot be reasonably avoided or stopped, to minimise and rectify such pollution or degradation of the environment." This EMPr must therefore form an integral part of the contract documents between Midmar Crushers (Pty) Ltd and the appointed contractor/s during the construction and operational phases of the development. This document outlines the methodology and duties required, such that construction, operation and rehabilitation can be achieved in an environmentally sustainable manner; with particular reference to the prevention and 1 DMR ref KZN30/5/1/2/2/188 MR. Page | 3
EMPr: Midmar Crushers Expansion 41717 mitigation of environmental impacts caused by activities associated with the project. Such mitigation measures will have a financial impact on the projects costings. This EMPr is a dynamic document that may need to evolve during its implementation period, such that it recognises any new issues that may arise; or changes in the parameters of identified issues which can be addressed with required / amended mitigation. Midmar Crushers (Pty) Ltd and its contractors are formally notified and are therefore required to take cognisance of the following principles throughout construction, operation and rehabilitation: 1.1 THE POLLUTER-PAYS PRINCIPLE This principle provides for “the costs of remedying pollution, environmental degradation and consequent adverse health effects and of preventing, controlling or minimizing further pollution, environmental damage or adverse health effects must be paid for by those responsible for harming the environment.” The Polluter Pays Principle must be rigorously applied throughout the construction and operational phases of this project. 1.2 PROGRESSIVE REHABILITATION Progressive rehabilitation must be undertaken throughout the various phases of the project where areas have been impacted. Rehabilitation should commence as soon as activities have been completed in specific areas and not at the end of the entire project. 2. ENVIRONMENTAL ASSESSMENT PRACTITIONER The EMPr was prepared by Terratest (Pty) Ltd. The details of the representative Environmental Assessment Practitioners (EAPs) who prepared the report are detailed in Table 2-1. Further, Curriculum Vitae of the detailed EAPs are provided in Appendix 1.

The amendment proposal includes for the westward extension of the existing Midmar Crushers (Pty) Ltd Mining Right Area. The extension of the current Mining Right Area will be limited to approximately 19.4ha and will include for the construction of a new access road, dolerite quarry pit, stockpiles, ablution facilities and site offices. The stages of development are detailed below: A. PRE-CONSTRUCTION / PLANNING PHASE: The Pre-construction / Planning Phase of the proposed extension will include for: The demarcation and survey of the 19.4ha area of land which will be cleared and grubbed; The surveying of the access road and two low-level bridge (causeway) crossings; The identification and cordoning off of ‘no-go’ areas for the construction and operational phases; and The planned layout of the operational area including for the location of stockpiles, overburden material, topsoil, ablution area, office area, emergency assembly point and stormwater controls. Page | 8
EMPr: Midmar Crushers Expansion 41717 The Pre-Construction and Planning Phase will also entail the finalisation of the Mining Plan and the methodology in which to undertake the mining activities. B. CONSTRUCTION PHASE: Construction Phase activities will include the following: a) Clear and grubbing All areas required for development will be cleared of vegetation and all topsoil removed and stockpiled on site, as per the Layout Plan, for use during the rehabilitation phase. All topsoil stockpiles will be surrounded by silt traps and/or berms to prevent run-off and siltation of watercourses (i.e. the Nguklu River). Topsoil stockpiles shall be kept separate from overburden stockpiles and will not be used for maintaining access roads. b) Levelling and platforming As the site is located on the side of a hill, a certain amount of levelling will be required prior to operation. In this regard, blasting, cut, fill and compaction activities will need to be implemented in order to create level platforms for the development of the quarry site and for the site camp. The overburden and topsoil stockpiles will be stored on the platforms and will be surrounded by silt traps and/or berms to prevent run-off and siltation of the nearby watercourse. c) Access road One new gravel access road from the existing quarry site, located to the east of the Nguklu River, will need to be cut to allow for the construction of the proposed low-level bridges (causeways). On the opposite side of the Nguklu River, on the southern corner of the proposed extension site, the road will be extended up from the existing Mining Right Area to the new site camp and quarry area. The gravel road will be 6m wide or less and will be approximately 790m long. An additional low-level bridge (causeway) is proposed to be constructed approximately 400m downstream (i.e. north) of the first low- level bridge. The gravel access road will tie into the second low-level bridge (causeway) to create a loop which will accommodate one-way traffic only. The one-way traffic system will eradicate the need for vehicle turning areas and will also increase road safety on the site. d) Low-level bridge (causeway) construction: Two low-level access bridges (causeways) will require construction across the Nguklu River. The low- level access bridges will be 6m wide or less. The carrying capacity of both bridges will be 50 tons each in order to allow for laden construction vehicles and operational vehicles to cross safely. Construction will necessitate the temporary impedance of water in the river during construction as a result of cofferdam2 construction. Conduits, such as pipes, will be placed in the watercourse during construction to allow for the free flow of water through built infrastructure where necessary. The causeway will be built to the KwaZulu-Natal (KZN) Department of Transport requirements for construction on bedrock, as detailed in Figure 4-2. Each access low-level bridge will allow for the single passage of one heavy construction vehicle or operational vehicle at a time. 2 A watertight enclosure pumped dry to permit construction work below the waterline. Cofferdams are commonly used for construction of bridge piers and other support structures built within water. Page | 9

EMPr: Midmar Crushers Expansion 41717 C. OPERATIONAL PHASE The operational phase of the quarry will involve: Blasting of the hard rock (dolerite) in the quarry; Utilising a rock breaker pecker where necessary to break blasted rock into further fragments for sizing purposes; and The loading of blasted dolerite onto tipper trucks and the transportation of loaded material along the dedicated access road to the existing processing area on the eastern side of the Nguklu River. The rock will be crushed and processed at the existing operational area (i.e. within the current Mining Right Area). The operational activities are described in further detail below: a) Defined quarrying area The quarry area will be clearly demarcated by beacons at its corners and along the boundaries to ensure visibility. The beacons will be firmly erected and maintained in their correct position throughout the life of the operation. This is likely to be conducted via the placement of large white painted boulders on the periphery of the site. The proposed quarry area will be approximately 9.73ha in size, comprised of approximately five benches with an average depth ranging between 9m and 15m. b) Blasting The existing Blasting Management Plan and principles utilised by Midmar Crushers (Pty) Ltd currently at the existing site will be implemented for the new extension site, with prior approval from the DMR, Quarry Operator and Owner. The Blasting Management Plan will make allocations for the undertaking of the following pre-blasting activities: Informing surrounding landowners and communities that may be impacted by the blasting of the timing and procedures of any blasting event; Inspection and photographic recording of all structural damage to any structures (buildings, roads etc.) within a radius of 500m of the blasting site, by an independent assessor, before any blasting is to take place; Making allocations for the use of nitrate-free explosives where-ever possible (i.e. methods such as drilling and black powder, expanding mortar or old fashioned “plugs and feathers”); and The use of noise mufflers and/or soft explosives during blasting. The Blasting Management Plan will include early warning specifications prior to blasting taking place informing surrounding residents of the intended blast. This will take the form of a siren that will sound 15 minutes before blasting that will be audible up to a radius of 1km from the site. During blasting events, if deemed necessary through an internal risk assessment, traffic signs will be utilised on the Main Road R617 advising motorists of scheduled blasting dates and times. In addition, traffic points men will be employed to temporarily stop vehicles travelling past the site. The Blasting Management Plan will include suitably approved noise and dust prevention measures, as well as approved measures to contain and limit the occurrence of fly rock during blasting. Further, the Blasting Management Plan will include the post-blasting monitoring of all structures identified to be of risk and recorded prior to the blasting activity. Any damage resulting from vibrations caused by blasting will be recorded and corrected by suitable measures in agreement with the owners of these structures. Upon implementation of mitigation measures to the structures, a photographic record will again be taken Page | 11
EMPr: Midmar Crushers Expansion 41717 of these structures. This assessing process and recording will be completed by an independent assessor. Any damage caused by possible fly rock will be recorded and addressed in a manner agreed to by the owner of the damaged structures. Upon completion of these mitigation measures, the affected structures will again be recorded photographically. c) Benching Depending on the bench configurations adopted and assuming average depths of exploitation ranging between 9m and 15m, a conservative estimate would yield between 1 and 2 million m3 of commercially crushable dolerite rock. A preliminary plan is provided in Section 7. d) Site camp and operational areas All areas required for operational activities will be cleared and grubbed as detailed previously. A detailed layout plan will be drafted detailing storage areas for stockpiles, laydown areas, as well as the office, ablution and eating areas. e) Crushing Blasted dolerite will be collected onsite via tipper trucks and transported back to the current Midmar Crushers (Pty) Ltd site via the dedicated access road and low-level bridges. All crushing activities will occur at the existing, authorised Midmar Crushers (Pty) Ltd site (ref: KZN30/5/1/2/2/188 MR) between 6am and 6pm. No crushing activities will occur at the extension area. f) Stormwater All stormwater from operational areas will be channelled into the operational dolerite pit on the extension site. This will be implemented via the construction and maintenance of diversions berms around the operational area. Berms will also be constructed on the downside gradient of the access road to prevent run-off from entering the Nguklu River and to prevent sedimentation thereof. The stormwater collected in the operational dolerite pit will be pumped into a bowser for use as a dust suppression mechanism on surrounding roads. g) Air quality Dust-buckets will be installed around the site to determine the impact of quarrying operations on air quality. All results will be recorded monthly in the Environmental File. Dust suppression mechanisms will be implemented on all access roads and all necessary areas within the pit. This will either be conducted via the spraying of water as collected in the quarry pit, or via chemical means. D. DECOMMISSIONING / REHABILITATION PHASE The decommissioning of the quarry will occur once the available resource (i.e. dolerite) has been quarried. All infrastructure will be demolished and moved off site. The overburden stockpile will be disposed of in the quarry pit and the benches sloped to allow for a gentler gradient. All compacted areas, including the access roads, laydown areas and platforms, will be ripped, topsoiled and seeded. The low-level bridges (causeways) will be removed and the profile of the Nguklu River reinstated. All disturbance associated with the extension area alongside the Nguklu River and within the riverine zone, will be rehabilitated. The following best practice procedures will also be followed: The excavated area (quarry pit) will serve as a final depositing area for the placement of overburden material; Page | 12
EMPr: Midmar Crushers Expansion 41717 Rocks and coarse material removed from the excavation will be dumped into the pit simultaneously with the overburden; Under no circumstances will waste be permitted to be deposited in the quarry pit; Waste material of any description, including receptacles, scrap, rubble and tyres, will be removed entirely from the quarry area and disposed of at a recognised landfill facility; Waste will not be permitted to be buried or burned on the site; Once excavations have been refilled with overburden, rocks and coarse natural materials and profiled with acceptable contours and erosion control measures, the topsoil previously stored, will be returned to its original depth over the area; The area will be fertilised, if necessary, to allow vegetation to establish rapidly; The site will be seeded with a local or adapted indigenous seed mix in order to propagate the locally or regionally occurring flora; and All infrastructure, equipment, plant and other items used during the quarrying period will be removed from the site. 3.2 SPECIFIC SPECIALIST REQUIREMENTS 3.2.1 Biodiversity and Wetland requirements A Biodiversity and Wetland Assessment was conducted by Terratest (Pty) Ltd with the following requirements being presented: LOSS OF VEGETATION Mitigation measures must include the following actions: No indigenous vegetation outside of the amended Mining Right Area footprint may be damaged. The area between the new quarry boundary (i.e. extension site) and the stream must be maintained as a buffer strip. This strip must have a minimum width of approximately 40m. An alien plant eradication programme must be undertaken and sustained in the 40m river buffer area. Key species to be targeted include Black Wattle, Lantana, Bugweed, Bramble, Syringa and Castor-oil Plant. The grassland areas must be managed for maximum biodiversity conservation. The first two actions are relevant and a regime of veld burns on a biannual basis must be established. The woody vegetation along the river must be protected by burning a five metre break along it’s margin each year. This action will encourage a natural ecotonal plant community to develop. While the above measures are intended to protect the remaining indigenous vegetation on the property, they will not be able to reduce the intensity or the significance of the proposed quarrie’s impact. However, they will prevent the secondary footprint of the operation from increasing. LOSS OF FAUNA Mitigation measures must include the following actions: Shortly prior to the start of any construction on the site, a chameleon capture and translocation operation must be undertaken. The animals captured must be translocated to a nearby site with suitable habitat. This site could be in the indigenous vegetation alongside the tributary stream west of the existing quarry. Page | 13
EMPr: Midmar Crushers Expansion 41717 The mitigation suggested will not prevent the impact on larger animal species from taking place. However, careful preservation of some natural vegetation will provide habitat for smaller species. WETLANDS No impacts on wetlands are anticipated. NGUKLU RIVER Prior to any work being conducted in the Nguklu River, the contractor must provide a method statement, wihc must be approved by the engineer and an appropriate environmental specialist. Mitigation measures put forward include the following actions: The lower end of the new quarry area should be enclosed by an earthen berm which will catch and contain dirty water and other materials from passing down the slope into the river. All the area between the new quarry boundary and the stream should be maintained as a buffer strip. This strip must have a minimum width of approximately 40m. An alien plant eradication programme must be undertaken, and sustained, in the buffer area including the strip of woody vegetation. Key species to be targeted include Black Wattle, Lantana, Bugweed, Bramble, Syringa, and Castor-oil Plant. Protect the woody vegetation from fire by burning a five metre break along its margin each year. This action will encourage a natural ecotonal plant community to develop. 3.2.2 Heritage requirements A Heritage Impact Assessment was undertaken by UMLANDO: Archaeological Surveys and Heritage Management, the results of which identified the following heritage features noted in Table 3-2. TABLE 3-3: Identified heritage features NO. SITE SOUTH EAST 1 Potential house or grave 29°34'38.85"S 30° 9'57.16"E 2 Potential grave 29°34'38.68"S 30° 9'57.62"E 3 Potential grave 29°34'37.82"S 30° 9'56.43"E 4 Potential grave 29°34'38.78"S 30° 9'56.70"E The specialist presented the following requirement: A 50m no-go buffer must be implemented around the areas identified or an extensive process of Public Participation is to be held as conducted in accordance to the National Heritage Resources Act (Act No. 25 of 1999) and the KwaZulu-Natal Heritage Acts of 1997 and 2008. As per the Layout Map, a 50m buffer has been implemented around the identified sites and as a result they do not fall within the site. Figure 3-4 highlights the no-go areas as identified by the Biodiversity and Wetland Specialist and Heritage Specialist. It further identifies 100m buffers from the Main Road R617 and existing Eskom powerlines which may not be encroached on (i.e. quarrying activities are not permitted in the buffer areas) unless permission is granted by the servitude holder.

EMPr: Midmar Crushers Expansion 41717 3.2.3 Noise requirements A Noise Impact Assessment was undertaken by IMA Trader 20 cc, the results of which produced a Noise Impact Management Plan, which is attached to this report as Appendix 2 and must be implemented. 3.3 APPLICABILITY OF EIA REGULATIONS (2014, AS AMENDED) In terms of the Environmental Impact Assessment (EIA) Regulations (2014, as amended), promulgated in terms of the National Environmental Management Act, 1998 (NEMA), certain Listed Activities are specified for which either a Basic Assessment (GNR 983 and GNR 985) or a full Scoping and EIA (GNR 984) is required. The following Listed Activities in Government Notice (GNR 983 (Listing Notice 1) and GNR 985 (Listing Notice 3) requiring a Basic Assessment (BA) Process are applicable to the proposed Mining Right amendment and associated development: GNR 983, Activity 12: “The development of (ii) infrastructure or structures with a physical footprint of 100 square metres or more where such development occurs a) within a watercourse b) in front of the development setback; or c) if no development setback exists, within 32 metres of a watercourse, measured from the edge of the watercourse, excluding (dd) where such development occurs within an urban area; (ee) where such development occurs within existing roads, road reserves or railway line reserves.” The proposed development will necessitate the construction of an access road and associated low-level bridges (No. two) over the Nguklu River. This will therefore require construction within a watercourse, thereby triggering this Listed Activity. GNR 983, Activity 19: “The infilling or depositing of any material of more than 10 cubic metres into, or dredging, excavation, removal or moving of soil, sand, shells, shell grit, pebbles or rock or more than 10 cubic metres from (i) a watercourse.” The construction of an access road and associated low-level bridges (No. two) over the Nguklu River will result in the deposition and / or removal of more than 10m3 from the watercourse, thereby triggering this Listed Activity. GNR 983, Activity 27: “The clearance of an area of 1 hectare or more, but less than 20 hectares of indigenous vegetation”. Construction activities will require the clearance of more than 1 hectare of indigenous vegetation on site, but less than 20 hectares. Therefore, this Listed Activity is triggered. GNR 985, Activity 4: “The development of a road wider than 4 metres with a reserve less than 13,5 metres in (d) KwaZulu-Natal (xii) outside urban areas (aa) areas within 10 kilometres from national parks or world heritage sites or 5 kilometres from any terrestrial protected area identified in terms of NEMPAA or from the core areas of a biosphere reserve”. The site falls within 5km of the Midmar Nature Reserve, a protected area, and construction of the proposed access roads will be wider than 4 metres. This Listed Activity is therefore triggered. GNR 985, Activity 14: “The development of (ii) infrastructure or structures with a physical footprint of 10 square metres or more in (d) KwaZulu-Natal (x) Outside urban areas (aa) Areas within 10 kilometres from national parks or world heritage sites or 5 kilometres from any terrestrial protected area identified in terms of NEMPAA or from the core area of a biosphere reserve.” Page | 16
EMPr: Midmar Crushers Expansion 41717 The construction of an access road and associated low-level bridges (No. two) across the Nguklu River will have a physical footprint larger than 10m2, within 5km of the Midmar Nature Reserve. Therefore, this Listed Activity is triggered. Page | 17
