Emerging Miners Workshop on Water Management

4 October 2016

Background - SWPN

Public-private-civil society

partnership

Launched

at COP 17 in Durban, South

Africa in 2011Members include DWS, Anglo, Exxaro, Nestle, SAB, Sasol, Eskom, SALGAThe SWPN strives to contribute to efficient, equitable and sustainable water supply and access to water for all South Africans through the identification and application of innovative and cost effective solutions and programmes. The mission of the SWPN is to close the projected 17% water gap by 2030 with the goal of improving water security in South Africa.Slide3

Accumulation of Mine Affected Water

Water Accumulation / Water contamination

Mine Residue deposits

Surface runoff

from dumps

Seepage through dump into groundwater

Plant and surface operationsRainfall runoff from plant and stockpile areas, haul roads, maintenance areas etc.Influx of water related to mining methods:Bord and pillar : 1-3%Stooping : 6-11%Opencast : 20%Opencast (rehab) : 14%Slide7

Water Hierarchy

Pollution Prevention

Minimization of Impacts

Reuse and Reclamation

Water Treatment

Discharge and DisposalSlide8

The mine affected water from the above areas

will

accumulate over time, resulting in excess polluted water, which

needs

to be managed

During the operational phase of a mine, the excess water can be managed and reused in the operationHowever this water accumulation creates a different challenge post closure and finding long-term sustainable solutions Slide9

Facility-level Factors

Regional Factors

Non-operational(old)Mining AMDIneffective water use licensingWeak DWA water use enforcement

Uneven DMR mining enforcement

Inconsistent regulation of mining

Inadequate regional planning

Unclear closure & liability requirements

Viability of collaborative models

Fragmented cooperation

Inadequate non-op AMD financing

Non-op decant & runoff

Problem Statement

Mine Water Management is a regional challenge

The need develop long-term sustainable solutions for water management and mine closure

The need to address the water gap facing the country

Organisations are working independently when implementing solutions

Challenges related to legislative approvals for water related activities and closure programmes e.g. Gaining approval and timeframes Requirement for significant technical, financial and legal inputWater pricing models for the treatment and re-use of mine affected water Institutional arrangements for the development, funding, build, operation and maintenance of mine water treatment projectsLack of a platform to facilitate collaboration between partiesThe Witbank Coalfields have 30-40 years remaining LOMSlide14

Current situation

M

ining

companies in the

region face similar challenges

Recent changes in legislation e.g. closure and financial provisionThe country is facing an increasing water deficit and the Olifants River catchment is currently one of the most stressed catchmentsIndustry has tried to collaborate previously by establishing committees and joint initiatives but with limited impact and not all stakeholders participated e.g. JIA, ORF Slide15

Mine Water Coordinating Body (MWCB)

Possible solution identified

The concept of the MWCB was born out of several studies undertaken by

the SWPN Effluent Waste Water Management Working Group

Proposed that the Body will initially consist of members from

key government departments and the mining industry Also proposed the other key stakeholders will be invited as the MWCB gains momentum e.g. local government, downstream irrigation schemes, agriculture sector, etc.Slide16

Value Proposition

Opportunity to address new legislation on Mine Closure and Financial Provision

NEMA now specifically provides that

liability includes

the responsibility for

extraneous or polluted water, continues after closure.The government may retain any portion of such financial provision for latent and residual safety, health and environmental impact which may become know in the futureSignificant financial implicationsJoint solutions to long-term water managementshared funding Previously funding only from large mining houses operating in catchmentFunding for the MWCB and its projects will come from public and private funding as well as other avenues such as international research and project fundingCompliance will be more financially viable and attractive to all membersSlide17

Value proposition

Create a neutral platform to discuss common challenges

Collectively address these challenges

Shared funding opportunities

Provision of

Financial and Administrative StructureProject management Research and implement short, medium and long term solutions for water management challenges Facilitate collaboration between members from both the public and private sectors Project OriginProject DestinationInceptionFeasibility

Actions to date

Appointment of Project Manager

engage with stakeholders

establish Mine Water Coordinating Body

Engagement with Proto CMA Chief Executive

Support for Mine Water Coordinating Body to become a committee under the CMA if selectedEngagement with DWS Mine Water Directorate teamSupport and will be a member of the MWCBEngagement with Anglo Coal, South 32, Exxaro, Eskom and Chamber of Mines All have indicated their willingness to join the MWCBChamber of Mines is the first to sign a letter of intentSlide20

Actions to date

Engagement with mining houses at Chamber of Mines Environmental Policy Committee (EPC) meeting in August

Concept of MWCB welcomed

Concerns raised as to how the Body will achieve it’s objectives

How will the MWCB be funded and continuity established

The MWCB must be formally constituted Engagement with Emerging Miners through Chamber Emerging Miners DeskSent overview of MWCB, and related documentation to all membersPresent MWCB at the Mine Water Workshop on 4 October 2016Slide21

Mine Water for Irrigation (Flagship Project)

First project underway

Irrigation with Mine Water

Project initiated together with WRC

Use of saline mine water for soy bean and wheat production

Partnership project – WRC, SWPN (MWCB), Anglo American, Exxaro, South32Demonstration project 60 hectares at Mafube Colliery mixture of rehabilitated and virgin landLand to be irrigated with mine water using centre pivots± 1 Ml/per day mine water required for irrigationSlide22
