Consolidation of Environmental Authorisations for the Sasol Mining (Pty) Ltd. Impumelelo Mine
Sasol Mining is an existing coal mining company situated in close proximity to Secunda, located approximately 16 km south-east of Kinross and 26 km south-west of Bethal in the Mpumalanga Province. Sasol Mining has been mining coal in the Secunda area for more than 30 years. The main purpose of Sasol Mining’s Secunda operations is to supply coal to Sasol Synfuels, which utilises various processes and beneficiates the coal into a number of products such as petrol, diesel, plastics and various chemicals.
In order to continue to satisfy existing market requirements of Synfuels, Sasol Mining has recently developed the Impumelelo Mine (also previously known as Block 2). The Impumelelo Mine is located to the south-west of Secunda, east of Greylingstad and north-west of Standerton in the Mpumalanga Highveld. The Impumelelo Mine commenced with operations in 2014 and has replaced the Brandspruit Mine operation.
The existing Impumelelo Mine consists of an area of approximately 30 000 ha in size. Coal is mined from the site utilising a combination of underground mining methods (bord and pillar, and high extraction / stooping). A conveyor from the Impumelelo Mine to the existing Sasol Coal Supply (SCS) blending plant located close to Brandspruit Colliery has been constructed, and is in regular use. The servitude for the conveyor belt includes a service road, water pipelines, power and communication lines.
Sasol Mining operates the Impumelelo Mine in line with several different approvals due to extensions and amendments that were applied for on the initial approvals. Sasol Mining wishes to consolidate their various approvals into two single working documents to streamline the mining and the management thereof for both the mine and the Competent Authorities that oversee the activities. The two documents to be compiled are:
- A single Environmental Impact Report (EIR) and Environmental Management Programme Report (EMPR) to consolidate the two EMPRs and four approvals currently applicable to the mine. This document has been compiled to comply with the requirements of the Mineral and Petroleum Resources Act (MPRDA), 2002 (Act No. 28 of 2002), as amended, and the National Environmental Management Act, 1998 (NEMA) (Act 107 of 1998), as amended.
- A single Integrated Integrated Water and Waste Management Programme (IWWMP) to consolidate the approved Water Use Licence (WUL) and various associated amendments and general authorisation confirmations. This document is intended to comply with the requirements of the National Water Act, 1998 (NWA) (Act 36 of 1998).
Sasol Mining does not intend to change or alter any of the approved activities included in the existing approvals, but does wish to consolidate the various documents to bring them in line with the latest requirements as well as in line with the approved Mining Right Boundary area.
Legislative Requirements – Consolidation of Environmental Impact Report (EIR) and Environmental Management Programme Report (EMPR)
Sasol Mining does not require approval of any new activities in terms of the MPRDA (2002) and the NEMA (1998). As there is not a legislated process for the consolidation of documents, the Competent Authority (the Department of Mineral Resources, DMR) was consulted and have advised that the EIR and EMPR can be consolidated without following the process for Environmental Authorisation due to the fact that no new activities or changes to approved activities are applicable. The DMR does, however, require the consolidated document to be subject to a Public Consultation Process.
Legislative Requirements – Water Use Licence (WUL)
The NWA (1998) requires an applicant to follow the Water Use Licence Application (WULA) process for all and any changes to a WUL. Sasol Mining will therefore be following the formal application process for the consolidation of their approved WULs for the Impumelelo Mine.
Purpose of this Background Information Summary
It is the purpose of this Background Information Document to form part of the environmental application processes undertaken in terms of the requirements of the:
- The National Environmental Management Act, 1998 (Act no 107 of 1998) and the Regulations thereunder.
- The Mineral and Petroleum Resources Development Act, 2002 (Act 28 of 2002), as amended December 2014, and the Regulations thereunder.
- The National Water Act, 1998 (Act 36 of 1998), and the Regulations thereunder.
Sasol Mining (Pty) Ltd. has appointed Clean Stream Environmental Consultants (Pty) Ltd. (CSEC), as required by Regulation 12(1) of the NEMA (1998), as the independent Environmental Assessment Practitioner (EAP), for the purpose of consolidating their approved EIRs and EMPRs as well as applying for a WUL in order to consolidate and replace their various Water related approvals (Water Use Licences and confirmations of General Authorisations).
Specialist Studies and Assessment of Impacts
As this project entails the consolidation of existing approvals, no new / additional specialist studies were undertaken, however all the previous studies undertaken were referenced and were applicable new monitoring data was also included in the document to describe the baseline as well as the current status of the environment. Impacts were assessed in line with the legislative requirements and available information, and are in line with the impacts identified as part of the approved documents.
Possible Environmental Impacts
The NEMA (1998) requires that the anticipated environmental, social, and cultural impacts be identified and described.
The impacts identified have been assessed in detail as part of the compilation of the previously approved documents, and are again included in the consolidated documentation. The following are some of the most notable impacts that may be associated with the Impumelelo Mine in the long term:
- Some noise may be generated by activities at and near the surface infrastructure areas.
- The underlying geology of the area may be disrupted.
- The groundwater quantity may be negatively affected due to the practising of high extraction mining.
- Subsidence may occur due to underground mining.
- Catchment yield may be affected.
- It is anticipated that a pollution plume and decant will develop after cessation of mining.
Benefits of the Project
The Impumelelo Mine is expected to have the following benefits over its life of mine:
- Sasol Mining will continue supplying jobs to its current employees.
- The surrounding communities will continue to benefit through direct and indirect income; as well as the mine’s use of local contractors and suppliers.
- The surrounding communities will benefit by the implementation of the approved mine Social and Labour Plan.
- Sasol Mining will continue to supply coal to the existing plant, which produces various products to market (including coal for power, fuel, etc.).
After mining has been completed, Sasol Mining (Pty) Ltd is committed to rehabilitate the site to a status as close as possible to that of the pre-mining status. In order to achieve this, the following closure objectives are included in the EIR and EMPR
- Rehabilitate any subsided land to be free draining, and vegetated (if required).
- Ensure all rehabilitated areas are free of alien invasive plant species and self-sustaining in terms of vegetation community.
- Ensure that any long-term impacts to groundwater have been effectively managed.
