1 PROJECT DESCRIPTION
1.1 Introduction
Zinoju Coal (Pty) Ltd (hereafter referred to as Zinoju) proposes the extension of the existing
discard dump facility at Magdalena Colliery, located approximately 25km north-northwest of
the town of Dundee, GPS Co-ordinates: 27° 56' 55.64”S; 30° 10' 39.28”E, KwaZulu-Natal. The
project is located within the magisterial district of Amajuba and the local Municipality of
Dannhauser in the KwaZulu-Natal Province (Figure 1).
In terms of the National Environmental Management Act, 1998 (Act No. 107 of 1998)
(NEMA), the proposed extension is listed as an activity that may be detrimental to the
environment and thus, requires authorisation from the Department of Economic
Development, Tourism and Environmental Affairs (DEDTEA), previously the KwaZulu-Natal
Department of Agriculture and Environmental Affairs (DAEA) before operations can
commence. The activities associated with the project are listed under both Government
Notice Regulations (GNR) 544 (Listing Notice 1) and GNR 545 (Listing Notice 2) and as such
require an application for Environmental Authorisation in the form of a full Environmental
Impact Assessment Process (EIA). Zinoju has appointed GCS as the Environmental Assessment
Practitioner (EAP) to undertake the EIA for the project and submit an application for
Environmental Authorisation (EA) to the DAEA. As part of this application process, an
Environmental Management Programme (EMP) (this document) has been developed in
compliance with Section 33 of GN. R543 of the 2010 Environmental Impact Assessment (EIA)
Regulations.
The relevant activities in terms of the Environmental Impact Assessment (EIA) Regulations
(Dated 2 August 2010) under NEMA are listed in Table 1 below:

1.2 Project Location
The Discard Dump is located at the Magdalena Colliery which is approximately 25km north-
northwest of the town of Dundee located on the Rem. of Farm Magdalena No. 7574 and
approximately 325km east-northeast of the City of Durban, in the province of KwaZulu-Natal.
The Colliery is located in the magisterial district of Amajuba and the local municipality of
Dannhauser. A locality map is presented in Figure 1. The Discard Dump extension is proposed
to be located contiguous to the existing Discard Dump and will be extended into Portion 1 of
the farm Mooidoorn Hoek No. 3722 as shown in Figure 3-2. Farm Magdalena No. 7574 is owned
by the Mchunu family and Portion 1 of Farm Mooidoorn Hoek No. 3722 is owned by Zinoju
Coal.
The proposed site for the discard dump extension at Magdalena is previously disturbed, and
was previously used for grazing by the local people surrounding the Magdalena Colliery.
Certain portions of the land have evidence of misuse in terms of large erosion gullies and
overgrazing. Local access roads are present throughout the site.

2 PROJECT DESCRIPTION
2.1 Existing Mining Operation
The existing Magdalena Colliery is operated by Forbes Coal (Pty) Ltd. The mineral deposit
extracted at the Magdalena Colliery is coal from two seams. The sub outcrop of the top seam
(Alfred) and the bottom seam (Gus). Mining occurs by opencast method using the sequential
roll over method and underground bord and pillar method accessed by an Adit system from an
old opencast high wall. The production rate of the mine is planned to increase to 152 000 Run
of Mine (ROM) tons per month. The life of the mine is expected to be 17 years.
The ROM from the underground operation is washed and screened at the washing plant
situated within the central section of the Magdalena site. The washed product is stockpiled
alongside the processing plant ready for distribution. The coal is transported from here by
road to the markets with a portion of the product being taken to the Coalfields site ready for
distribution by rail. All ROM from the open cast operation is however taken straight to the
Coalfields plant for washing and processing.
The site’s existing discard dump is located to the south of the washing plants. Deposition is by
upstream mechanical tipping truck. The dump maintains five metre wide berms at every 5
metres vertical lift to enable access by tipper trucks. However, Forbes is planning on creating
higher terraces of 13m. Slope stability is maintained by an overall slope of 1 in 3. Pollution
control measures are installed to ensure clean and dirty water separation such as cut off
trenches. An under drainage system is used to collect seepage.
The existing discard dump takes coal discard from both the Magdalena and Aviemore
collieries. Presently, the discard dump is nearing capacity and needs to be extended to
ensure disposal capacity requirements of the life of the mine for both these operations. The
existing dump has a design life of 3 years and storage capacity of circa 2 million tonnes
(53000 tonnes per month) and is therefore not sufficient to accommodate the life of mine
requirements. Therefore, it is proposed to extend the discard dump to achieve a design life
of 22 years with a maximum storage capacity of 9.5 million cubic metres. Refer to Figure 2
for the proposed discard dump extension layout.

2.2 Proposed Discard Dump Extension
The existing discard dump is 3.33ha in extent and is proposed to be extended (increased in
size) by approximately 36ha. The details of the discard dump extension have been taken
from the Draft Design Report prepared by AfriCan Innovative dated 19 June 2012. The
proposed project will involve establishment of the following:
1. New tailings storage facility (extension to existing)
2. Return water dam
3. Decant system
4. Under drainage
5. Clean and dirty water separation canals
6. Solution trench
7. Access road
2.2.1 Tailings Storage Facility (Discard Dump Extension)
The proposed geometry was influenced by the existence of underground mine workings to
the east of the discard dump extension stretching from the north to the south. The design
criteria are as follows:
• Type of facility: Coal discard dump
• Design life of mine: Estimated at: 22 years
• Tonnage production per year: 640 000t
• Assumed in-situ density: 1.469tm-3.
• Total tonnage in life of mine: 14 080 000t
• Total volume of residue: 9 584 751.5m3
2.2.2 Return Water Dam
The return water dam design will be designed to adhere to the National Water Act (1998)
and SANS 10286: 1998 regulations, and therefore the criteria for the design of the same are
as follows:
• Design return period: I:100year
• Design flood: 146.2mm
• Required volume: 14 500m3
• Freeboard: 0.8m
• Depth including freeboard: 4m
12-094 14 September 2015 Page 8
Zinoju Coal (Pty) Ltd Magdalena Colliery Discard Dump Extension: EMP
The return water dam will be designed with a clay / HDPE composite liner in line with
statutory requirements for surface and ground water pollution control.
Due to the topography of the site, two return water dams will be designed: one with a
capacity of 8000m3 and the other for a capacity of 7500m3. Under normal operations, the
volume of water in the return water dam will be kept not more than 4 000m3.
2.2.3 Decant System
The coal will be deposited in “dry” state and as such, no conventional decant system will be
designed for this project. However, momentary rising of the water table can be expected
from seepage especially after a prolonged low frequency storm. Thus, supernatant (surface)
water will need to be drained off the top of the dump as soon as possible. To achieve this,
an “emergency type” pump budge will be utilised. The system must be sized to decant a 24
hour 1:100 year storm in not more than 72 hours (three days).
2.2.4 Under Drainage
Previous site studies have indicated that the water table is high and that there is need for
pollution control measures to ensure seepage does not come into contact with groundwater
under the impoundment. The topography of the site is such that seepage flows downhill.
Thus, an under-drainage system will be incorporated at the toe to capture all seepage and
also help with consolidation necessary for strength gain and stability of the discard dump.
The system will consist of perforated or slotted geo-pipes just behind the starter push-up
walls connected to out-falling solid pipes discharging into the solution trench and then to the
return water dam.
2.2.5 Clean and Dirty Water Separation Canals
To prevent the contamination of stormwater, cut off trenches will be excavated in phases on
the upstream of the facility to divert “clean” storm water received on the upstream
catchment to the stream without passing through the contaminated site. The positions of
the storm diversion trenches will be clearly marked on the detailed layouts.
2.2.6 Solution Trench
The solution trench will be designed to contain flows resulting from the cumulative effects
of the seepage from the under drains and discard dump supernatant water resulting from a
1:100 year 24 hour storm.
2.2.7 Access Road
Since the envisaged method of deposition is upstream mechanical tipping by truck, the
12-094 14 September 2015 Page 9
Zinoju Coal (Pty) Ltd Magdalena Colliery Discard Dump Extension: EMP
impoundment has been designed with five metre wide berms at every five metre vertical lift
to enable access by tipper trucks at any point around the dam. Maintenance shall follow
procedures stipulated in the Operations Manual to ensure access under any weather
conditions and at any time.
2.2.8 Method of Deposition
The method of deposition will be by upstream mechanical tipping truck which is the current
method of deposition. In addition, 5 metre wide berms will be created at every 5 metres
vertical lift to enable access by tipper trucks. Slope stability will be maintained by an overall
slope of 1 in 3.
Pollution control measures such as cut off trenches will be installed to ensure clean and
dirty water separation. In addition, an under drainage system will be used to collect seepage
as process water which will initially be directed to a Return Water Dam.
3 OBJECTIVES AND PRINCIPLES
3.1 Objectives of the EMP
The purpose of the EMP is to manage the impacts associated with the construction,
operational and closure activities within the Magdalena Colliery Discard Dump Extension
project. Environmental impacts and associated mitigation measures and recommendations
identified during the course of the EIA are included to ensure they are adopted and
implemented. In addition, the EMP is designed to assist Zinoju and their contractor/s to
plan and implement effective site-specific strategies that will minimise the potential
environmental impacts associated with their activities and maintain compliance with
environmental legislative requirements. This EMP serves as a stand-alone document to be
disseminated to, and used by, the contractor/s and project managers during all phases of
the project. By its very nature, the EMP is a dynamic document and updating may be
required (with written approval from the DAEA).
Note that should the authorisation from the DEDTEA be granted for the project, this
document is to be updated with any specific conditions contained therein.
The purpose of the EMP is to:
• Promote understanding of the common environmental impacts associated with the
construction and possible mitigation measures.
12-094 14 September 2015 Page 10
Zinoju Coal (Pty) Ltd Magdalena Colliery Discard Dump Extension: EMP
• Ensure that the construction activities associated with the project are undertaken
in a controlled and organised manner, thereby managing and minimising potential
environmental and social impacts.
• Encourage good management practices through planning and commitment to
environmental issues.
• Outline the developer’s environmental management commitments for the site.
• Recognise health and safety issues related to the project.
• Act as a performance standard that activities can be audited against.
• Provide rational and practical environmental guidelines to:
- Minimise disturbance of the natural environment.
- Prevent or minimise all forms of pollution.
- Comply with all applicable laws, regulations, standards and guidelines for
the protection of the environment.
- Adopt the best practicable means available to prevent or minimise adverse
environmental impacts.
- Develop waste management practices based on prevention, minimisation,
recycling, treatment or disposal of waste.
- Describe all monitoring procedures required to identify impacts on the
environment.
3.2 Environmental Principles and Best Practice Guidelines
• The environment is considered to be composed of both biophysical and social
components.
• Construction is a disruptive activity and all due consideration must be given to the
environment, including the social environment during the execution of the project
to minimise the impact on affected parties.
• Minimisation of areas disturbed by construction activities (i.e. the ‘footprint’ of the
construction area) should minimise many of the construction related environmental
impacts of the project and reduce rehabilitation requirements and costs.
• All relevant standards relating to international, national, provincial and local
legislation, as applicable, should be adhered to. This includes requirements relating
to waste generation and emissions, waste disposal practices, noise regulations, road
traffic ordinances, etc.
• Every effort should be made to minimise, reclaim and/or recycle waste materials.

5 IDENTIFICATION OF ENVIRONMENTAL IMPACTS
The negative environmental impacts and issues identified to date have been summarized
into the following categories:
5.1 Construction Phase
The construction phase consists of the following activities that may give rise to
environmental impacts:
• Construction of:
o tailings Storage Facility
o return water dam;
o under drainage;
o cut-off trenches and storm water berms
o Clean and Dirty Water Separation Canals;
o pollution control dam (s);
o Solution trench; and
o Access and haul roads
o Footprint area clearance.
o The maintenance and upgrading of the total clean water and dirty water
diversion trenches; and
o Handling of truck fuel and oil spills.
12-094 14 September 2015 Page 12
Zinoju Coal (Pty) Ltd Magdalena Colliery Discard Dump Extension: EMP
5.2 Operational Phase
During the operational phase of the proposed discard dump at Magdalena Colliery the
following activities that may impact on the health and social aspects of the surrounding
communities will occur:
• Use of slurry ponds to collect and keep or dam all the coal slurry coming from coal
mining and preparation processes;
• Use of return water to receive and temporarily store storm run-off from the slurry
dams;
• Maintenance and inspection of slurry dams, return water dam and the effluent
trench on a regular basis (deficiencies will be rectified immediately) and
• Stockpiling and transporting of coal discard material.
5.3 Decommission and Closure Phase
Closure for mining activities is highly important as far as the environmental factors are
concerned. If mitigation measures are not followed properly it could have devastating
impacts. As closure without mitigation factors could have permanent impacts on the
environment. The decommissioning of the proposed Magdalena Discard Dump extension will
form part of the mine closure.
The mine will be required to apply for a Closure Certificate according to Section 43 of the
MPRDA. Section 43 (1) of the MPRDA stated that “the holder of a … mining right …remains
responsible for any environmental liability pollution or ecological degradation, and the
management thereof, until the Minister has issued a closure certificate to the holder
concerned”.
During closure, most discard dump infrastructure will be dismantled and removed from site
and all disturbed areas will be rehabilitated, except a few roads remaining to provide
access for monitoring and follow-up rehabilitation.
It is therefore assumed that all environmental impacts will be successfully addressed and
managed at this phase. When the decision is taken to decommission the mine, the activities
below will be implemented:
• Dismantling of infrastructure / removal of infrastructure:
12-094 14 September 2015 Page 13
Zinoju Coal (Pty) Ltd Magdalena Colliery Discard Dump Extension: EMP
o Linear infrastructure constructed will be removed if it proves to inhibit land
use at decommissioning. Where possible, infrastructure will remain for
future operations as determined by Forbes Coal or future land use (social
investment opportunities). The soils and land capability will be
rehabilitated to near pre-mining conditions;
o All roads will be rehabilitated by ripping these structures to a depth of 500
mm; and
o All fences erected will be dismantled and either disposed of at a permitted
disposal site or sold as scrap (provided these structures will no longer be
required by the post-mining land owner). Fences erected to cordon-off
dangerous excavations will remain in place and will be maintained as and
when required.
• Removal of waste;
• Amelioration and vegetation of all disturbed areas;
• Maintenance the re-vegetated dump up until succession initiate to create a
sustainable cover;
• Monitoring of key environmental variables (i.e. soils, vegetation, groundwater and
surface water) in order to demonstrate stability of the rehabilitated dump;
• Weed management after closure, limited to discard dump activity affected area.
• Monitoring will be undertaken for a specific period after closure or up until the
discard dump area create a sustainable cover and ecosystem and
• Cessation of labor contracts.
• Rehabilitation of pollution control dams and reuse of water contained therein for
dust suppression.
• Surface and ground water monitoring.
A summary of the impact assessment ratings are tabulated below.

6.4 Environmental Awareness and Compliance
The philosophy adopted in this EMP is derived from the principles of the National
Environmental Management Act (No. 107 of 1998) (NEMA) which states that development
must be socially, economically and environmentally sustainable. Sustainable development
requires that:
• The disturbance of ecosystems and loss of biodiversity are avoided (minimised or
remedied).
• Pollution and degradation of the environment are avoided or minimised and
remedied.
• Waste is avoided or minimised and re-used or re-cycled where possible and
otherwise disposed of in a responsible manner.
• A risk averse and cautious approach is applied.
• Negative impacts on the environment and on people’s environmental rights be
anticipated and prevented, and where they cannot altogether be prevented, are
minimised and remedied.
NEMA makes provision that anyone who causes pollution or degradation of the environment
is responsible for preventing impacts occurring, continuing or recurring and for the costs of
repair of the environment.

6.5 Proposed Mechanisms for Monitoring Compliance and Performance
Assessment
Appropriate monitoring and review of the EMP is required to ensure effective
implementation of the EMP and to identify and implement corrective measures in a timely
manner. In the event where discrepancies are identified, the problem must be investigated
and attended to. All the results obtained during environmental monitoring must be
documented for audit purposes.
Compliance with the approved EMPR and EMPR Amendment has to be audited in terms of
the Mineral and Petroleum Resources Development Act (MPDRA), 2002 (R527 r55).
Specifically, the regulation requires that monitoring of the EMPR is undertaken on an
ongoing basis and performance assessments (audits) are undertaken every two years. The
continued appropriateness and adequacy of the EMPR needs to be evaluated during the
audits. The specifications contained within this EMP are included in the EMPR Amendment
to be submitted to the DMR, and will be audited against during the EMPR audits.
6.6 Amendments to the EMP
Amendments to the EMP may be required as the project proceeds. Any proposed
amendments to the EMP will be confirmed with Zinoju and the EAP prior to being issued as
a formal amendment to the DEDTEA. Copies of the amendments will be issued to all
relevant parties.
6.7 Roles and Responsibilities
The project applicant, Zinoju Coal (Pty) Ltd, will be ultimately responsible for
environmental management on site during all phases of the project. Contact details for
parties involved in the application and relevant authorities are outlined in Table 4 below.

7 ENVIRONMENTAL MANAGEMENT PROGRAMME
The management of Magdalena Colliery is committed to managing and rehabilitating the
mine area in a responsible manner. Magdalena Colliery will use cost effective Best Available
Technology (BAT) to adequately manage the mine so as to limit the negative environmental
impacts. These impacts may arise from normal mine operation or the expansion and
addition of mining infrastructure.
Where pertinent negative issues have been identified (impacts with a medium to high
significance), specific measures are presented to address the issue. For impacts not of a
significant nature, measures have been presented for the prevention of impacts as well as
the overall mitigation of impacts on specific biophysical and social aspects. Management
measures that the mine intends to implement are defined in terms of objectives. The
recommended management measures for each of the impacts are described in this section.
Management measures that the mine intends to implement are defined in terms of
objectives. The recommended management measures for each of the impacts are outlined
in Table 6-1 below.
NOTE: The management measures detailed below are specific to the extension of the
discard dump and are supplementary to those contained in the approved MPRDA EMPR
and Addendum.
