AfriSam (South Africa) Properties (Pty) Ltd: Ulco Cement Plant and Mining Operation Integrated Water and Waste Management Plan Project number: AFR-ULC-17-08-16 Report date: August 2020 Ulco Cement Plant and Mining Operation Integrated Water and Waste Management Plan i Executive summary AfriSam (South Africa) Properties (Pty) Ltd (“AfriSam”) appointed Shangoni Management Services (Pty) Ltd. (“Shangoni”) to compile an Integrated Water and Waste Management Plan (“IWWMP”) for the Ulco Cement Plant and Mining Operation (“Ulco operation”) and to also include information relating to the proposed Bergville Project in support of a Water Use Licence Application (“WULA”). The existing Ulco operation is situated adjacent to the R31, and 8 km north-west of the R370. The town of Delportshoop is situated approximately 13.6 km south-east of Ulco operation, while Kimberley is situated approximately 65 km in the same direction. The Ulco operation is situated within the Dikgatlong Local Municipality and the Frances Baard District Municipality. Mining of high-grade secondary limestone reserves began in 1936, when Union Lime mined it for lime. In 1949, it was decided to mine the low-grade limestone material for cement and the company built two wet process kilns (Kiln 1 and Kiln 2) and associated cement mills for the cement manufacturing process. Subsequently in 1964, two further kilns (Kiln 3 and Kiln 4) were added on to increase the production capacity. In 1985, Union Lime Company was purchased by Anglo Alpha. In 1985, Anglo Alpha began mining primary limestone reserves and commissioned a fifth kiln (UK5), with a capacity to produce a maximum of 4 400 tonnes of clinker per day. The old lime kilns and cement kilns were decommissioned in 1992. In 1995, Anglo Alpha changed name to Alpha (Pty) Ltd, that subsequently changed its name to Holcim (South Africa) (Pty) Ltd in January 2004 and finally to AfriSam (South Africa) Properties (Pty) Ltd in April 2008. In addition to limestone, shale is also mined on site. The limestone and secondary components are all mined in multi-bench opencast quarries. Acceptable secondary limestone reserves in the current mining area at the Ulco operation are starting to run low (refer to item 1 on the layout map for the location of the existing quarry). The estimated time horizon remaining is less than 5 years. Already quality consistency on the limestone stockpiles are getting more difficult to maintain. Therefore, AfriSam is proposing to expand the Ulco operation’s mining operation onto the north-eastern portions that are adjacent to the current operation, and still within its existing mining right. The limestone resources are available north of the Ulco operation on the opposite side of the R31 provincial road and bounded by the rail line further north. The proposed new quarry will be accessed via a slot in the limestone barrier (~100 m) between the mining areas and the R31, and twin tunnels under the R31 large enough to safely get the existing side-tipping road trucks through. The Ulco operation is in possession of an approved water use as follows: AfriSam South Africa (Pty) Ltd.: Ulco operation (licence number 10/C33C/ABEGJ/1776), approved 11 January 2015 (refer to Annexure A). Purpose and scope The purpose of this document is to provide sufficient information that will enable informed decision making through a detailed description of the proposed water use scenario and shortcomings in respect to the relevant water management measures. A list of the general and specific management commitments pertaining to this IWWMP is also included in order to show Ulco operation’s commitment Ulco Cement Plant and Mining Operation Integrated Water and Waste Management Plan ii towards continuous improvement in water management and to reduce the impacts on water resources to as low as reasonably practicable. This IWWMP is also the technical information document in support of the WULA for the relevant water uses under Section 21 of the National Water Act, 1998 (“NWA”), associated with several water uses that were omitted from the current WUL. This document is based on the following technical guidelines: • Best Practice Guideline 1.1: Integrated Mine Water and Waste Management developed by the Department of Water Affairs (DWAF, 2008); • Operational Guideline to assist in the compilation of an Integrated Water and Waste Management Plan, First Edition: February 2010; • External Guideline: Generic Water Use Authorisation Application Process, as compiled by the DWA, dated November 2007; and • Regulations regarding the procedural requirements for water use licence applications and appeals, Government Notice 267, dated 24 March 2017. In summary, this IWWMP presents: • General information pertaining to the operation and a background description of the activity, description of the property and the specific purpose for the development of the IWWMP; • Broad description of the Ulco operation, products, business and corporate policies; • Water uses (new, existing, lawful, exemptions and general authorisations); • Environmental context (climate, surface water, groundwater and socio-economic environment); • Analysis and characterisation of activities (organisational structure, training, awareness, monitoring and control); • Risk assessment in relation to process water, storm water, groundwater and waste (methodology, potential impacts and significance of risks to the environment); • Water and waste management strategies, specifically focussing on process water, storm water, groundwater and waste); and • Regulatory status of water use activities accompanied by the section 27 motivation. Water use activities A detailed list of water use activities and description of these activities are included in Chapter 3 below. Ulco operation is currently engaging in the following water uses (as authorised under the WUL (Licence No.: Licence No.: 10/C33C/ABEGJ/1776): Section 21(a) of the Act: taking water from a water resource; Section 21(b) of the Act: Storing water; Section 21(e) of the Act: Engaging in controlled activity: irrigation of any land with waste or water containing waste; Section 21(g) of the Act: Disposing of waste in a manner which may detrimentally impact on a water resource, subject to the conditions as set out in Appendices I, III and VI of the Licence; and Ulco Cement Plant and Mining Operation Integrated Water and Waste Management Plan iii Section 21(j) - removing, discharging or disposing of water found underground if it is necessary for the efficient continuation of an activity or for the safety of people. The following water use activities are applied for as part of the Bergville Project: Section 21(a) of the Act: taking water from a water resource; Section 21(b) of the Act: storing water; Section 21(c) of the Act: impeding or diverting the flow of water in a watercourse; Section 21(f) of the Act: discharging waste or water containing waste into a water resource through a pipe, canal, sewer, sea outfall or other conduit; Section 21(g) of the Act: disposing of waste in a manner which may detrimentally impact on a water resource; Section 21(i) of the Act: altering the bed, banks, course or characteristics of a watercourse; and Section 21(j) of the Act: removing, discharging or disposing of water found underground if it is necessary for the efficient continuation of an activity or for the safety of people. Main water use and waste related risks and mitigation measures A detailed risk assessment for the activities at the Bergville Project is contained in Chapter 5 of this report. The main water use and waste related risks for the activities are associated with surface water, wetland and groundwater impacts. Mitigation measures are discussed in Chapter 5 of this report, with a detailed integrated water and waste management plan included in Chapter 6 of this report. The integrated water and waste management plan focuses on minimising the impact of the activities on the surface water and groundwater resource.
