5 Much of the water supplied to the metropolitan areas and some mining developments is transferred from the Vaal River system via Rand Water. In many of the streams and impoundments, water quality is severely compromised by the proportionately large return flows. The utilisation of the projected surplus water in the Crocodile (West) River catchment will be for transfer to the Lephalale area (the Lephalale mineral belt in the Mokolo River is accorded by Government a Strategically Important Project) as well as for re-use schemes within the catchment.

6 Yield / Water Requirements (million m 3 / annum) INDICATORS: 1. High demand, with target WC/WDM achieved 2. AMD: Neutralised only, then discharged 3. Unlawful abstraction from Liebenbergsvlei eradicated 3800 High Water Requirement Scenario with Water Conservation and Demand Management Short-term excess yield Yield reduction due to dilution wastages 3200 Deficit System Yield Deficit Polihali Dam Yield Years AMD pumping commences. Yield increases by 76 million m 3 /annum First transfer from LHWP Phase II

Main source of the debt - money owed by the Water Trading Entity to the Trans Caledon Tunnel Authority. Auditor General Report: Qualified audit /16 financial year: significant irregular, fruitless and wasteful expenditure. Revenue Collection: Approximately R9.8 million is owed to the DWS by municipalities and Water Boards. Corruption Allegations: Lesotho Highlands Water Project, notably, the Polihali Dam

8 Department of Water and Sanitation Report (CER) (Continued) Legislation: Uncertainty and incoherence in the policy and legislative environment related to water and sanitation. (Water and Sanitation Bill; Water and Sanitation Master Plan; Proposed revision of the pricing strategy for water use charges; revision of the norms and standards for setting water services tariffs) Catchment Management Agencies and Water Tribunal Blue and Green Drop Reports: Blue Drop and Green Drop reports have not been published since 2013; DWS does not timeously remunerate laboratories and they subsequently withhold data or results; since 2015 Green Drop Assessments was not undertaken due to the lack of capacity. Dysfunctional wastewater treatment works and lack of remedial action: The majority of plants (259) assessed are in the high risk Compliance Monitoring And Enforcement, Licence Conditions And Reporting: in 2016 only 85 of the 177 vacant posts, for the Blue Scorpions, were filled; no reporting on compliance monitoring and enforcement; of the 111 mines 55 mines are significantly non-compliant

16 Rand Water Quarterly Water Quality Status of the Rietspruit Catchment 01 Oct Sep 2017

17 APRIL 2017 INTEGRATED ENVIRONMENTAL AUTHORISATION APPLICATION PROCESS FOR THE PROPOSED CESSATION OF PUMPING AND ASSOCIATED CLOSURE OF THE UNDERGROUND WORKINGS OF THE EZULWINI OPERATIONS OF SIBANYE GOLD Surface Water Based on the assessment of the impacts on surface water from the cessation of pumping from Ezulwini the following conclusions can be made: The cessation of pumping will have a very high impact on the surface water quantity in terms of availability, in the Kleinwes Rietspruit and in terms of the availability of water in the catchment. In addition, further downstream where water from urban areas is being discharged into the stream, water qualities with respect to e.coli may deteriorate due to the significantly reduced dilution from the water currently being discharged from the mine. However, although the impact on surface water quality further downstream on the Kleinwes Rietspruit has a high negative rating, Sibanye cannot be held accountable for the detrimental influences by third parties on water quality downstream of the operations.

18 National Water Act 36 of 1998 (NWA) Pollution means the direct or indirect alteration of the physical, chemical or biological properties of a water resource so as to make it- Less fit for any beneficial purpose for which it may reasonably be expected to be used Harmful or potentially harmful to the welfare, health or safety of human beings; to any aquatic or non-aquatic organisms, to the resource quality; or to property Who is responsible/liable? (Section 19 of the NWA) An owner of land, a person in control of land or a person who occupies or uses the on which- Any activity or process is or was performed or undertaken; or Any other situation exist, which causes, has caused or is likely to cause pollution of a water resource, must take all reasonable measures to prevent any such pollution from occurring, continuing or recurring. A CMA may direct any person who fails to take the measures required under subsection 1(1) to- commence taking specific measures before a given date Diligently continue with those measures Complete them before a given date Should a person fail to comply, or comply inadequately with a directive the CMA may take the measures it considers necessary and recover the costs jointly and severally fro the following persons Any person who is or was responsible or who directly or indirectly contributed to the pollution or the potential pollution The owner of the land at the time when the pollution or potential pollution occurred, or that owner s successor-in-title The person in control of the land or any person who has a right to use the and at the time when the activity or the process is or was performed or undertaken; or the situation came about or any person who negligently failed to prevent the activity or the process being perform or undertaken or the situation from coming about

19 Chapter 15 Appeals and Dispute resolution This Chapter establishes the Water Tribunal to hear appeals against certain decisions made by a responsible authority, catchment management agency or water management Institution under the Act. The Tribunal is an independent body, whose members are appointed through an independents selection process and which may conduct hearings throughout the Republic. A person may appeal to a High Court against a decision of the Tribunal on a question of law. This chapter also provides for disputes to be resolved by mediation, if so directed by the Minister.

20 NATIONAL ASSEMBLY FOR WRITTEN REPLY QUESTION NO 2306 DATE OF PUBLICATION IN INTERNAL QUESTION PAPER: 14 AUGUST 2017 (INTERNAL QUESTION PAPER NO. 26) Mr N R Mashabela (EFF) to ask the Minister of Water and Sanitation: (1) Have any appeals been lodged with her in terms of section 41(6) of the National Water Act, Act 36 of 1998; if not, why not; if so, how many have been (a) lodged and (b) decided; (2) will the Water Tribunal be retained as an appeal authority in the upcoming draft Water and Sanitation Bill; if not, why not? NW2545E REPLY: ---00O00--- (1) From 2008 to 2017, a total of 414 appeals have been lodged, and 4 decided; 74 withdrawn by appellants. (2) No. The reason for discontinuation Water Tribunal is that the Water Tribunal is not an efficient, cost effective and speedy mechanism for the resolution of appeals arising from the implementation of the Act. The new Bill seeks to provide for an administrative dispute resolution mechanism which is more efficient, cost effective, and quicker O00---

21 Chapter 7 Catchment Management Agencies This Chapter provides for the progressive establishment by the Minister of CMA. The purpose of establishing these agencies is to delegate water resource management to the regional or catchment level and to involve local communities, within the framework of the national water resource strategy established in terms of Chapter 2. THE PROPOSED CONSOLIDATION OF THE CATCHMENT MANAGEMENT AGENCIES INTO ONE NATIONAL CATCHMENT MANAGEMENT AGENCY It has recently come to our attention that the Minister of Water and Sanitation (Minister) has taken the decision to commence the process of consolidating the nine catchment management authorities (CMAs) into a single national CMA. It would fly in face of existing national water policy that provide for the decentralisation of and public participation in water governance.

22 Acid Mine Drainage (AMD) AMD associated with mining activity long recognised problem. In 1903 referred to as an established phenomenon concerning pumped water on the Witwatersrand. The highest cost burden of combating salinity is currently being carried by the household sector and not by industry as might be expected. Internalising externalities the polluter pays principle is based on the internalisation of externalities and there is central to the equitable resolution of pollution costs currently being borne by the end user. The following determinants in the mine void water exceed the Maximum Allowable Limits (Class II) of the SABS 241 Drinking Water Standard, in many cases by several orders of magnitude: ph, EC, TDS, So4, Fe, Mg, Ca, Mn, Al, Pb, Co and Ni. It can be assumed with a reasonable amount of certainty that most of the other metals would also be present in elevated concentrations. (O Flaherty 1903). (WRC Report No 486/1/95.

24 Figure 2: Dilution Releases from the Vaal Dam Ref. Richard Holden. TCTA Failure to establish a sustainable long-term solution to AMD would lead to the prolonged reliance upon funding from the general fiscus, increase of the salt load in the Vaal River, which could only be mitigated by releases from the Vaal Dam, and a subsequent deficit in the Upper Vaal which could have severe economic impacts if a drought occurs (the last drought ended in December 1995).

25 AMD: CURRENT STATUS 2012: Immediate and Short Term Treatment of AMD (High Cost High Energy Pump and Treatment Option) ph adjustment: It should be noted that the metals have not simply disappeared but that they have merely changed to a different oxidation state, which changed them from a soluble form to a solid form. The process could be reversed and the contaminants mobilised, should the water become acidic. Reference: Harmony EIA.
