3 FOR OFFICIAL USE ONLY INDONESIA DAM SAFETY PROJECT LOAN AND PRoJEwr SuMMARY Borrower: Loan Amount: Terms: Project Description: Benefits and Risks: Republic of Indonesia US$55.0 million equivalent Twenty years, including five years of grace, at the Bank's standard variable interest rate. The main objective of the project is to reduce the risk of dam failures in Indonesia through establishment of national dam safety institutions and carrying out a program to improve the safety of existing dams. The project would be implemented over a six-year period ( ) and include the following main components: (a) support for the recently established Dam Safety Commission (DSC) and Dam Safety Unit (DSU) at central Government level and Dam Monitoring Units (DMU) at central and local dam owners' levels; (b) provision of basic dam safety facilities at dams where at present such facilities are lacking; and (c) implementation of remedial works at dams with safety deficiencies. Training and technical assistance would be provided to assist the Directorate General of Water Resources Development (DGWRD) with the implementation of the proposed project. The project's main benefit would be a reduction in the risk of dam failures and there are no major risks associated with its implementation. There is a relatively small risk that it may take longer than at present anticipated for the new dam safety institutions to become fully operational and for their staff to be trained to the level required to manage a nation-wide program. However, Government fully recognizes the importance of setting up a regulatory body to enhance the safety of the nation's dams. The Dam Safety Commission would be the key body to guide the dam safety program toward a national level with clear public accountability for safety while leaving operational accountability with the dam owners. Proper orientation and training of the members of the Dam Safety Commission would be a critical element of the project during the first one or two years of its implementation.

9 - 1 - CHAPTER 1 PROJECT AND SUBSECTOR BACKGROUND Background 1.1 Dams have been constructed in Indonesia since the early 1900s, initially for irrigation purposes, but increasingly as multi-purpose dams for irrigation, power generation and flood control. The development of Indonesia's water resources has been a key factor for rapid rural development, transition to rice self-sufficiency, and a notable drop in poverty levels. Agricultural growth has outpaced population growth by 1 percent per year for two decades, while even more rapid expansion of the services and manufacturing sectors have shrunk agriculture's share of GDP to 20 percent. Faced with growing non-agriculture water demands and diminished prospects for new irrigation, particularly on Java, the main challenges are sustaining existing infrastructure and increasing the efficiency of water use. The rapid economic development also has increased the awareness among the public for the need to protect society against potential disasters due to dam failures. The Government of Indonesia (GOI) has therefore requested Bank assistance for a Dam Safety Project which would help establish permanent dam safety institutions, provide basic safety facilities to all dams where such facilities currently are lacking, and implement remedial works at schemes with safety deficiencies. Dams in Indonesia 1.2 At present about 120 large 1/ and numerous small dams and weirs are in operation in Indonesia. The dams have significantly contributed to the country's development: they serve about 1 million hectares of irrigated lands, generate 6,000 GwH of electricity, protect large downstream areas from floods, and are a major source of water supply for urban centers. Over 100 of the dams are single purpose, of which over 90 serve irrigation schemes and 10 generate power. There are about 15 multi-purpose dams, serving irrigation and power, and in 10 cases also serving flood control and/or water supply. Some 100 of the 120 dams are located on Java, including 13 of the 15 multipurpose dams. The largest arable land resources are on Java and over 90 of the dams are being used for irrigation. Most of the older dams on Java are relatively small and were built to supply local irrigation systems and villages. The more recently built dams tend to be larger and serve larger areas. About one-third of the existing large dams were built before / Dams having a height of 15 meters or more and/or a reservoir capacity of at least 500,000 cubic meters.

10 About 95 of the dams are owned by the Ministry of Public Works (MPW) and operated by the Provincial Water Resources Services (PWRS) with technical oversight by MPW's Directorate General of Water Resources Development (DGWRD). Prior to 1965 almost all dam projects were planned, constructed and operated under the direction of MPW. Since then the hydropower facilities were separated from MPW and placed under the State Electricity Corporation (PLN). The PLN is the second largest dam owner and operates at present nine dams. The Jatiluhur Authority operates 1 dam, the Jasa Tirta (Brantas Authority) 6 dams, and other public and private owners another 10 dams. Details on age, size and ownership of Indonesia's large dams are given in Annex 1, Table Several technical factors need to be considered with regard to the safety of the existing dams. First, where past maintenance programs have been weak, the probability of failures increases. Second, potential losses below dams due to failures are increasing with expanding populations and property development, often located near the banks of the downstream river channels. Third, the technical knowledge of dam design, hydrologic analysis, monitoring instrumentation, and quality control of materials and construction have improved over the past three decades. Many of these advances have occurred after the completion of some of the older facilities. Moreover, Indonesia is located in an active seismic zone which requires special attention in dam design and maintenance to assure greater strength or flexibility of the dams. The knowledge and methodology of estimating the potential magnitude of floods and earthquakes has improved over the past two decades and the stability and safety of some of the older facilities need to be reassessed in regard to these two factors. Institutional Framework for Damn Safety 1.5 The responsibility for inspection and monitoring of dams for safety lies at present entirely with the owner-operators. At most of the larger power and irrigation dams, staff is assigned full time to read monitoring instruments, keep operational records, and inspect the facilities for signs of distress. While these activities are vital for ensuring safety, a clear need exists for the establishment of a formal system of independent inspections and reporting on the safety and operational condition of the darns. Many countries have adopted formal dam safety regulations and publicly supported programs of inspection, evaluation and regulation to consistent standards in order to ensure adequate flood handling capabilities and structural soundness of the existing dams. In Indonesia the requisite regulations and organizational arrangements to ensure consistent dam safety actions still are lacking at this time. The DGWRD has therefore been charged with the preparation of a dam safety program which initially would cover all MPW-owned dams and eventually be expanded to include all large dams in Indonesia (see para. 5.1). This would require the establishment of a separate dam safety organization with a staff of technical specialists who are independent from the operating units. The envisaged dam safety organization would be a regulatory agency with the task of setting standards, making periodic inspections, conducting evaluation of the safety status, issuing notices of deficiencies to the owners, followed by monitoring of the corrective work performed. Such an organization should also review the designs and construction of new dams to assure that the necessary safety features are included.

11 The International Commission of Large Dams (ICOLD), made up of technical professionals and multi-country commissions from all over the world, produces technical guidelines and model dam safety programs. The ICOLD guidelines and other technical publications comprise the basic requirements for successful dam safety programs which Indonesia intends to follow. However, there are regional and local conditions that must be considered in the process of specifying the guidelines and standards for Indonesia. A country-wide commission of large dams exists in Indonesia which has access to all ICOLD reference materials. 1.7 Over the last decade staff of the Research Institute of Water Resources Development located in Bandung have received training in dam safety inspections and evaluation procedures. In some situations they have carried out safety assessments on MPW dams. However, they have not the administrative authority to direct owner agencies to take the necessary remedial actions. Many of the staff of the Institute are now involved in research programs and are qualified to provide the nucleus for a new dam safety organization.

13 -4 - Bank Involvement in Dams in Indonesia CHAPTER 2 BANK INVOLVEMENT 2.1 The Bank has supported a large number of irrigation, hydropower and water supply projects in Indonesia during the past 25 years. Some of these projects included the construction of dams but in most projects the head works already existed and the investments involved only down stream conveyance and distribution facilities. As the demand for dry season water supplies and power continues to increase in the country, the long-term operation of storage dams and ensuring their safety gains more importance. A summary of irrigation lending appears in Table During the last decade, the Bank has assisted GOI in carrying out regular safety evaluations on existing dams that would serve new Bank funded irrigation and municipal water projects. Under the agreement for the West Tarum Canal Improvement Project (Loan 2560-IND), the Bank required a safety evaluation of the Jatiluhur Darn whose operation was to provide the water for a new irrigation system as well as for expanding municipal supplies for the Jakarta metropolitan area. The Jatiluhur Dam has a net storage capacity of 2.4 billion cubic meters, a potential irrigated area of 300,000 hectares, and a power generating capacity of 900 Gwh per year. The safety inspection, investigation and evaluation was performed in 1992/93 by a foreign consultant firm which concluded that the dam was not of sufficient strength to withstand some of the loading conditions that could occur. The consultants also noted that for a number of years the dam's operators had been restricting releases because of apparent weaknesses observed when the reservoir level was lowered. Subsequently, a dam review panel was created to advise MPW on the results and conclusions of the investigations. In January 1993, MPW (the owner of Jatiluhur Dam), the consultant, the panel, the original design firm, and the Bank held a joint meeting to review the history of design and construction of the dan, discuss the subsequent observations and records, review the results of the current investigations, and evaluate the appropriateness of the proposed remedial actions. Based on the evaluations made by the consultant and the panel, MPW concluded that major remedial work should be performed at the dam. 2.3 The Bank's involvement in the inspection and safety evaluation at Jatiluhur led to detailed discussions with MPW on the broader issue of country-wide dam safety. During 1992, MPW employed foreign consultants to inspect and assess the safety status of several other dams under its jurisdiction. The extent of remedial work needed for these dams led to a full evaluation of Indonesia's dam safety procedures and a decision to institute a country-wide dam safety program. In February of 1993, the MPW issued a decree setting out the basic provisions for expanded dam safety activities and for the

14 -5 - creation of a dam safety organization. Subsequently, a special committee of MPW staff was assigned to outline a program for dam safety and propose a program suitable for funding by the Bank. Assisted by two consulting firms, the Directorate of Irrigation-I (DOI-1) prepared an initiating report for a proposed dam safety project which would include the establishment and support of a dam safety organization and implementation of remedial work for dams with identified deficiencies, including Jatiluhur Dam. During 1992 and 1993, about 36 MPW-owned dams were inspected and evaluated by consultants. Subsequently, designs for remedial works have been prepared for 13 dams, including Jatiluhur. Issues and Lessons Learned 2.4 While dam safety measures have been addressed in past Bank-funded projects with dams, available evidence suggests that maintenance programs have declined over time resulting mainly from financial constraints. There are no mandatory government policies and procedures requiring continuation of timely monitoring, analysis and evaluations of the safety status of dams. Many of the staff that had been trained for these activities have by now left for other organizations, taken jobs in the private sector, or have been given other assignments. Consequently, the degree of attention now being given to each dam varies considerably and is quite inconsistent. The large dams, especially PLN's revenue earning power dams which can support good maintenance programs, appear to have been cared for quite well and have good monitoring and record systems in place. However, on irrigation projects with older dams, scant financial resources have been applied toward maintenance and as a result many of them show deterioration and signs of distress. The lesson learned in countries with well established dam safety programs is that regulatory agencies responsible for overseeing the programs are indispensable. Government Strategy 2.5 The Government wishes to upgrade its capability to manage the country's water resources in order to: (a) ensure adequate supplies for human consumption; (b) maintain food security; (c) relieve poverty; (d) balance regional development; and (e) utilize water resources efficiently and in an integrated and sustainable manner. With the increasing demands for water, Government gives priority to upgrading operations of existing infrastructure. The Government proposes to establish a regulatory body to ensure safety of existing and future dams, starting with those owned and operated by MPW/PWRS and eventually expanding the oversight function to cover all dams in Indonesia. Bank Strategy and Rationale for Bank Involvement 2.6 The Bank is in broad agreement with the Government's objectives for irrigation and water resources development. The project is fully consistent with the Bank's Country Assistance Strategy discussed by the Board on April 12, The project would: (a) strengthen public sector management by establishing regulatory institutions to protect the country against the risk of dam failures; and (b) contribute to effective management of water resources through the provision of basic safety facilities and implementation of remedial works at Indonesia's existing large dams to enhance their

15 -6 - safety status. The project is part of a coordinated lending program for water resources development, with each operation focussed on important and complementary objectives. The other projects are: (a) (b) (c) the approved Groundwater Development Project (Loan 3588-IND) and the appraised Integrated Swamps Development Project (FY94) would both exploit the natural resources in less developed regions and promote the objectives of regional equity and poverty; the approved Watershed Conservation Project (Loan 3658-IND) focuses on natural resources management in critical watersheds; and the appraised Java Irrigation Improvement and Water Management Project (FY94) would focus on efficient water resource utilization in selected Java basins and improve the productivity of existing infrastructure. Due to its close association with water resources related programs in Indonesia, and given its support for the establishment of dam safety institutions in several other borrowing countries, the Bank is well placed to assist Indonesia with the development of a national dam safety program.

17 -8- CEHAPER 3 TIE PROJECT Project Objectives 3.1 The main objective of the project is to reduce the risk of dam failures in Indonesia through: (a) establishment of dam safety institutions; (b) periodic inspections and safety evaluations of all large dams; (c) provision of basic safety facilities at existing dams where such provisions are now lacking; and (d) implementation of remedial works at dams with safety deficiencies. The dam safety program would start with inspection, evaluation and remedial work on the MPW dams and in due course be expanded into a national program covering all dams in Indonesia. Project Area 3.2 The project area encompasses the entire country of Indonesia. Due to the concentration of the population and extensive agricultural operations in Java, over 80 percent of the large dams are located there, with the remainder scattered geographically around the country (Annex 1). Project Description 3.3 The proposed project would be implemented over a six-year period ( ) and support the recently established Dam Safety Commission (DSC) and a Dam Safety Unit (DSU), and one central and about 11 local Dam Monitoring Units (DMU). Equipment, staff training and technical assistance would be provided by the project in support of this effort. The project would also provide basic safety facilities for all existing dams now lacking such facilities, and carry out remedial works at Jatiluhur Dam and other MPW dams with safety deficiencies. Detailed Features 3.4 Dam Safety Institutions (Base Cost US$2.6 million, see Annex 2). The project would provide office space, computers, printers, files, technical reference materials, transport and basic office and field equipment for the operation of the following dam safety institutions: (a) Dam Safety Commission, consisting of representatives of all dam owners, Indonesia's Commission of Large Dams, and other agencies with public safety interests; the DSC would oversee the activities of the DSU, review

18 9- and approve dam safety guidelines and standards, and supervise enforcement of dam safety legislation; (b) (c) (d) Dam Safety Unit, established initially as an entity within DGWRD under the new Directorate of Water Utilization and Conservation and which eventually would evolve into an independent regulatory agency; the DSU, with an initial technical staff of about 20 persons would conduct inspections and evaluate the safety status of all dams in Indonesia, prepare guidelines and standards for dam safety requirements, and provide technical training and guidance to owners' staff in charge of operation and maintenance of the dams. central Dam Monitoring Unit in Jakarta, to be established within DGWRD under the new Directorate of Technical Guidance and which would consist of three technical staff; the central DMU would direct the routine safety inspections and evaluations for all MPW/PWRS dams, keep basic records for the dams as specified by DSU, and liaise with DSU on all safety matters; and about eleven local Dam Monitoring Units, of which about eight in the provinces and three for large schemes (i.e., Jatiluhur, Solo and Brantas); the local DMUs would have about two to four technical staff each and be responsible for routine surveillance, inspection and accurate reporting of all required information. 3.5 Training (Base Cost US$1.2 million, Annex 3). The training would include on-the-job training by consultants during the early years of the project, formal workshops, seminars and instruction provided by visiting specialists, and study tours for the selected engineering personnel to other countries that have active and effective dam safety programs and agencies that manage them. Training equipment and materials would be provided by the project. The training activities would be more prominent in the early years of the project but would continue throughout the project period. 3.6 Basic Safety Facilities (Base Cost US$7.2 million, see Annex 4). The project would provide basic safety facilities for all dams where such facilities are now lacking. This would include: (a) (b) (c) carrying out of surveys of all dams and associated structures to provide information for detailed inspection; installation of communications equipment to improve routine operational communications and ensure advance notice of flood conditions; installation of instrumentation, including seepage recorders, stand pipe piezometers, reservoir level gauges and recorders, and rain gauges, in order to improve the recording of basic data relevant to the safe operation of the dam and reservoir;

19 - 10- (d) (e) clearance of dam and surrounding areas to allow detailed inspection of dam and associated structures; and emergency actions, where required, to ensure safety of dam and associated structures. The central DMU would collaborate with dam operating units and/or consultants to collect the required information and to procure and install the needed basic safety facilities. The basic facilities would be identified and installed early in the project period in order to assist in the collection of data needed to determine if any major remedial works are required. 3.7 Remedial Works (Base Cost US$59.5 million, see Annex 5). Following detailed safety inspections carried out in 1992 and 1993, the project would provide for remedial works on 22 dams in order to upgrade their safety condition. The largest portion of the identified work is for the Jatiluhur Dam and adjacent facilities (base cost of about US$19.5 million). The works would include strengthening of the main dam, raising and strengthening of the reservoir embankments, repair of two tail race conduits, and improving access roads. Under the Central and West Java Irrigation Development Project (Loan 2649-IND) and West Tarum Canal Improvement Project (Loan 2560-IND) final or preliminary designs have been prepared for remedial works at another 11 dams (Category A), and preliminary cost estimates following detailed inspection have been prepared for another 10 dams (Category B). During project implementation inventories and hazard rankings would be prepared, safety inspections conducted, and remedial works requirements identified, at all other large MPW/PWRS dams (Category C). A provision equal to about 40 percent of the total cost of the remedial works has been made for works at the Category C dams. 3.8 Project Management (Base Cost US$0.3 million). The project would provide for office space, equipment, transport, and other facilities for a small project management team, comprising about ten staff, which would be located in a new Subdirectorate of Large Structures under the Directorate of Technical Guidance. 3.9 Consultants Services (Annex 6). The project would provide for the following consultants services: (a) (b) for institutional capacity building: assistance in establishing dam safety institutions and training of staff, requiring about 150 foreign and 280 local staff months (base cost US$4.7 million); for implementation support: (i) (ii) construction supervision of remedial works at Jatiluhur Dam, requiring about 65 foreign and 150 local staff months (base cost US$1.8 million); and surveys, investigations, designs and supervision of installation of basic dam safety facilities, and design and construction supervision for remedial works at dams other than Jatiluhur; DGWRD's own staff are expected to perform up to 25 percent of this work while

20 local consultants, in some instances assisted by foreign consultants, would perform the balance through a series of annual contracts (base cost US$4.7 million). In order to expedite the start of project activities after project approval, the consultants referred to under (a) and (b)(i) above should be employed by January 15, An assurance to that effect has been obtained from GOI during negotiations. Status of Preparation and Implementation Schedule 3.10 The project has been prepared by DGWRD assisted by several teams of consultants. The draft preparation report covering institutional strengthening, basic dam safety facilities, and remedial works for dams, other than Jatiluhur, was issued in September 1993 and formed the basis for the appraisal. Designs for remedial works for 11 dams have been completed while the detailed inspection has been completed for another 10 dams. With regard to Jatiluhur Dam, the draft tender documents for remedial works were completed in December 1993 and are now being finalized following comments by the Bank. Prequalification of contractors has been completed. Remedial works at Jatiluhur Dam are scheduled to start in mid-95. Terms of Reference for the two main consultancies have been reviewed by the Bank and are now finalized. The short lists of firms have been approved by the Bank. The project implementation schedule is at Annex 10. Environmental Impact 3.11 The project would help protect the environment through the establishment of permanent dam safety institutions and by raising the safety level of the country's existing dams. The Subdirectorate of Large Structures of DGWRD would conduct a field review and environmental screening, to be documented in a brief report, for each dam to be included in the remedial works program. If the screening would reveal potential negative environmental impacts, an Environmental Impact Assessment (EIA) would be prepared in accordance with MPW standard procedures (PP51) and processed through the Environmental Control Agency (BAPEDAL). Any mitigation measures required would be performed prior to signing of the remedial works contract, or made a part of the remedial works contract and performed by the contractor The remedial works on the dams are not expected to necessitate the acquisition of additional land for new rights-of-way, and therefore the issue of resettlement of people is not expected to arise. However, should land acquisition be required, GOI would notify the Bank on the acreage of acquisition, the present use and ownership of the land, and the effects on people, including relocation, if needed. A determination would be made at that time of the necessity for MWP to prepare a resettlement plan. GOI has agreed that such plan, if needed, would be prepared in accordance with policies, planning principles, institutional arrangements, and design criteria agreed with the Bank (see Annex 5) and would be subject to review and approval by the Bank. Assurances to this effect have been obtained from GOI during negotiations.

21 CHAPTER 4 PROJECT COSTS AND FINANCING Project Costs 4.1 Total project cost, including contingencies, is estimated at US$97.4 million of which US$27.9 million would be foreign exchange and US$7.6 million duties and taxes. Base costs are expressed in 1994 values. Physical contingencies are estimated at 5 percent for remedial works at the Jatiluhur main dam, 15 percent for identified but as yet not fully studied remedial works at ten dams, and 10 percent for all other civil works and for equipment and vehicles. No physical contingency has been added to the global cost estimate for unidentified civil works (Category C dams). Price contingencies are based on an estimated annual local inflation rate of 5.5 percent and a foreign inflation rate of 2.5 percent from FY95. Project costs are summarized in Table 4.1 below and detailed in Annex 7.

GOI would finance the balance of US$42.4 million equivalent, or 44 percent of project cost. The project financing plan is summarized in Table 4.2 below and detailed in Annex 9, Table 1.

22 Table 4.2: PROJECr FINANCING PLAN (US$ million) Source of Finance Local Foreign Taxes Total Percentage GOI Bank Total C. 27M9 Li 22 s Procurement 4.3 General. Procurement of goods, works and services, with the exception of vehicles, would be undertaken by DGWRD units at the national and provincial levels in accordance with procedures acceptable to the Bank. GOI would use its own resources to fund the purchase of vehicles (US$0.5 million) in accordance with a schedule agreed with the Bank. An assurance to that effect has been obtained from GOI during negotiations. 4.4 Civil Works. International competitive bidding (ICB) procedures would be used for the award of three separate contracts for the remedial works at Jatiluhur Dam and reservoir (US$23.0 million). Prequalification of contractors for these works has been completed which was acceptable to the Bank. Remedial works at the other dams (US$43.6 million) and the provision of basic dam safety facilities (US$7.2 million) would be individually much smaller in scope than the works at Jatiluhur. Also, these works would be geographically dispersed and thus unlikely to attract interest from foreign contractors. Therefore the works would be awarded under local competitive bidding (LCB) procedures acceptable to the Bank and open to foreign contractors. However, ICB procedures would be followed when the cost estimate of the works would exceed US$3.0 million per contract. Where feasible, remedial works at adjacent dam sites would be combined in one contract. For bid comparisons under ICB procedures, local contractors would be allowed a 7.5 percent margin of preference. Small remedial works and provision of basic safety facilities up to a maximum of US$50,000 for each dam may be executed by the owners' own maintenance crews on force account. The Bank's standard bidding documents would be used for ICB contracts and GOI's standard bidding documents, acceptable to the Bank, would be used for LCB contracts. 4.5 Equipment. Equipment (US$0.7 million) would be procured following LCB procedures acceptable to the Bank, or on the basis of international and for local shopping for items estimated to cost less than US$50,000 per contract up to an aggregate amount of US$500,000. In the latter case at least three quotations from foreign and/or local suppliers would be obtained. 4.6 Training and Consultants Services. All training activities (US$1.3 million) would be carried out by direct contracting, or within existing Government training facilities. Consultants providing technical assistance for the establishment of dam safety institutions (US$5.2 million) and for construction supervision of remedial works at Jatiluhur Dam (US$1.8 million) would be selected after inviting proposals from international and national firms which already have been shortlisted by GOI, and are

23 acceptable to the Bank. Other consulting services for surveys, investigations, designs and construction supervision (US$6.1 million) are relatively small in size and scheme specific and would be arranged primarily through national consultants. An assurance has been obtained from GOI during negotiations that all consultants would be selected in accordance with the Bank's Guidelines and engaged according to the Bank's Standard Conditions of Contract for Consultants. 4.7 Review of Procurement.

24 Disbursements 4.8 All project activities are expected to be completed by March 31, 2000, and the Loan closing date would be September 30, Disbursements from the Loan would be made for: (a) (b) (c) 55 percent of expenditures on civil works; 100 percent of foreign expenditures (CIF) for directly imported equipment and materials, 100 percent of local expenditures (ex-factory) for locally manufactured equipment and materials, and 65 percent of locally procured items; and 100 percent of expenditures on consultants services and training. 4.9 Disbursements under the project would be made against Statement of Expenditures (SOE) for contracts for works valued at less than US$1,000,000, equipment valued at less than US$100,000, consultants services valued at less than US$100,000 for firms and US$50,000 for individuals, and for training activities. Contracts disbursed under SOEs would be based on model bid documentation approved by the Bank. Disbursement for all other expenditures would be on the basis of full documentation. Documentation for SOE expenditures would be retained by implementing agencies and the Directorate General of Budget (Ministry of Finance) and be made available for review by Bank supervision missions Special Account. To facilitate disbursements, a Special Account would be established in the Bank of Indonesia to be maintained by the Director General Budget in the Ministry of Finance (MOF). The Special Account would be maintained in US dollars with an initial deposit of US$3.0 million (equivalent to the average disbursements during a four month period). The Special Account would be for withdrawals, in all categories, relating to all foreign and local currency expenditures as long as the withdrawals do not substantially deplete the balance in the Special Account. The Government would request once per month replenishment of the Special Account or if its balance falls below 80 percent of the initial deposit, whichever occurs first. Accounts and Audits 4.11 The Project Manager in the new Subdirectorate of Large Structures in DGWRD would have overall responsibility for setting up and monitoring the use of an uniform project accounting system for all project expenditures incurred at the national and provincial levels. The Subdirectorate in Large Structures would maintain accounts for equipment procured on behalf of the project and for training and technical assistance. The Kanwil offices of MPW in the provinces would maintain accounts of project related expenditures incurred on the various dam schemes, and transmit accounts reports to the Subdirectorate of Large Structures on a regular basis. Assurances have been obtained from GOI during negotiations that: (a) the project's records and accounts, including the SOEs and Special Account, would be audited annually by the Government Audit Agency (BPKP), or another qualified auditor acceptable to the Bank; and (b) certified copies of the audit reports would be submitted to the Bank starting December 31, 1995 for fiscal year 1994/95, and subsequently no later than six months after the end of each fiscal year. The

25 audit reports would contain a separate opinion as to whether the SOEs submitted during each fiscal year, together with the procedures and internal controls involved in their preparation, can be relied upon to support the related withdrawals DGWRD would carry out technical audits of the remedial works, basic safety facilities and training components of the project. The terms of reference for these audits would be prepared, and organizational arrangements proposed, by GOI not later than June 1, The technical audits, acceptable to the Bank, would be carried out every twelve months during the implementation of the project, commencing not later than April 1, 1996, and copies of the audit reports would be furnished to the Bank for information commencing not later than October 1, Assurances to this effect have been obtained from GOI during negotiations.

27 CHAPTER 5 ORGANIZATION AND MANAGEMENT Organization and Management 5.1 The Directorate General of Water Resource Development (DGWRD) in the Ministry of Public Works would be the executing agency for the project. A major reorganization of DGWRD is currently underway and is scheduled to be completed by June 15, Understandings were reached during project appraisal, and confirmed during negotiations, that the new Dam Safety Unit (DSU) would be located in a different DGWRD directorate than the central Dam Monitoring Unit (DMU) and project management. The DSU, together with the Dam Safety Commission (DSC) were established under a Public Works Ministerial Decree issued in February The two entities would constitute the nucleus for an independent public dam regulatory agency covering all dams in Indonesia and is expected to be located initially within the new Directorate of Water Utilization and Conservation of DGWRD. An assurance has been obtained from GOI during negotiations that not later than April 1, 1997 GOI would establish a national dam safety regulatory agency with jurisdiction over all dams in Indonesia. Eventually, it is expected that the dam regulatory agency would be organizationally separated from DGWRD. The central DMU would monitor all MPW/PWRS dams on behalf of the owner and, together with project management, be located in a proposed new Subdirectorate of Large Structures in the new Directorate of Technical Guidance of DGWRD (see Chart 1). 5.2 The DSC would have a membership of about persons and serve as the advisory board for the dam safety program. The Chairman and members of the DSC have been appointed under a Decree of the Minister of Public Works issued in April The Chief of the DSU would be the Secretary of the DSC and the Director General of DGWRD would initially be the Chairman. The DSC would meet at least quarterly. 5.3 The DSU is the technical agency responsible for carrying out the inspections, evaluations, reviews, preparation of guidelines and standards, safety training for the dam owners' O&M staff and preparation of annual program reports. The DSU would be organized in four sections, i.e., field monitoring and inspection, dam design and review, data and records, and training coordination. Its staff of about 20 technical persons would be assigned on a project basis according to experience and availability (see Chart 2). An assurance has been obtained from GOI during negotiations that operational guidelines for DSC and DSU, acceptable to the Bank, would be issued not later than May 31, 1995.

28 The central DMU and project management would be located in the proposed new Subdirectorate of Large Structures in the Directorate of Technical Guidance. The Chief of the subdirectorate would be the Project Manager (PIMPRO) and be responsible for the planning and implementation of all project components, including contracting of remedial works, procurement and installation of basic dam safety facilities, and organization of the staff training program. He would direct the project consultants, coordinate work programming and reporting, and would be the primary liaison with the Bank (see Chart 3). The Chief of the DSU and the Project Manager were appointed in April The DGWRD has a good record in the execution of works. The main objective of the ongoing reorganization is to strengthen and integrate planning and design of water resources at the regional level. As a result, DGWRD is likely to emerge stronger once the process has been completed. Monitoring and Evaluation 5.5 During project implementation, and also thereafter, DSU would keep detailed records of the dam safety program activities. Annually, the DSU would prepare a report summarizing the year's activities, progress made, and details on the dams requiring remedial work still to be carried out. The records system would include the key information on remedial work performed along with the inspection records. One of DSU's primary activities is to continually evaluate the effectiveness and impact of the dam safety program. As development below dams increases and the dams age, risks would need to be assessed continuously and policies possibly adjusted. The DSC would evaluate these data and the DSU's overall performance and decide on any adjustments in the program that may be needed. Annual Work Plan and Budgets 5.6 Project activities would be financed in accordance with existing GOI procedures for financing Bank-assisted projects. Budget allocations for project activities would be based on annual work programs prepared by DGWRD and agreed to by BAPPENAS. To ensure that adequate funds would be provided for planned project activities, GOI would submit to the Bank for its review and comments: (a) not later than September 30 each year, a work program and cost estimates for the following fiscal year; and (b) by December 31 each year, budget proposals for the agreed work programs. Budget allocations would be based on the agreed work programs taking into account the Bank's comments. Assurances to this effect have been obtained from GOI during negotiations. 5.7 During the project period, the operating cost of the DSU and the DSC would be covered under MPW's annual budget. Eventually, when the DSU would have developed into a national dam regulatory agency, the possibility of establishing an independent source of funding for its operating cost, preferably by the dam owners, would be determined. A transparent fee structure for certification of new dams or reissuance of inspection certificates for existing dams, would help ensure the independence and sustainability of the regulatory agency and indicate to present and future owners the costs and risks of operating their dams. Assurances have been obtained from GOI at negotiations that by March 31, 1998 a proposal for a funding structure for the operation

29 of the national dam safety program would be sent to the Bank for review and comment, and that thereafter an action plan would be prepared and carried out taking into account the comments of the Bank. 5.8 The large majority of the dams, where remedial works would be carried out under the project, are used for irrigation. Recovery of capital cost is as yet not considered a feasible proposition. Priority is being given to the financing of the cost of system operation and maintenance through the introduction of a user fee system. A major portion of the remedial works would be carried out at the multi-purpose Jatiluhur Dam and reservoir which, in addition to supplying at present some 260,000 ha with irrigation water, generates about 900 Gwh annually and supplies raw water to the Jakarta Metropolitan area. The facilities at Jatiluhur are operated and maintained by the parastatal Jatiluhur Authority. This Authority owns the power station, offices, staff houses and O&M facilities, while GOI owns the main dam, dikes and access roads. The Authority sells raw water to Jakarta and power to PLN at contracted rates and cost sharing arrangements which do not include depreciation or capital cost of the GOI-owned facilities at Jatiluhur. Taking into account these existing arrangements, the Bank agrees that the Government funds the remedial works at Jatiluhur at 100 percent equity, as for all other Government-owned irrigation dams. Supervision Missions 5.9 The Bank would supervise the project semi-annually. Details on timing and proposed composition of the missions is presented in Annex 11.

31 Benefilts and Justification CHAPTER 6 PROJECT JUSTIFICATION AND RISKS 6.1 The project would increase efficiency in the safe operation and maintenance of dams. The main benefit would be a reduction of risks of dam failure. Such a failure would result in: (a) damage to downstream property and environment; (b) possible loss of life; (c) sudden loss of benefits from the reservoir supply; and (d) replacement cost of the dam itself or construction of an alternate water supply. The project provides public safety and to postulate benefits on the basis of the probabilistic computation for the potential of a dam failure is not common practice. However, during the final design, alternatives would be compared and least cost solutions would be sought for the needed remedial works. Project Sustainability 6.2 The Dam Safety Unit to be established under the project would evolve into a public regulatory agency and require continuous funding by GOI of its recurrent costs. The annual operating expenses would be relatively small when compared to the potential losses due to dam failures in the absence of a national dam safety program. The owner agencies would remain legally responsible for the performance of their dams. They would have the obligation to fund remedial works, either from their revenues (PLN, private owners) or through annual budget allocations (MPW), as deficiencies are discovered by the safety inspections and evaluations. Project Risks 6.3 There are no major risks for the project. The introduction of a formal dam safety program would reduce the probability of dam failure and the associated loss of life and property. There is a relatively small risk that it may take longer than at present anticipated for the new dam safety institutions to become fully operational and for their staff to be trained to the level required to manage a nation-wide program. However, Government fully recognizes the importance of setting up a regulatory body to enhance the safety of the nation's dams. There is no reason to expect GOI to reduce its support. The Dam Safety Commission would be the key body to guide the dam safety program toward a national level with clear public accountability for safety while leaving operational accountability with the dam owners. Proper orientation and training of the members of the Dam Safety Commission would be a critical element of the project during the first one or two years of its implementation.

32 CHAPTER 7 AGREEMENTS REACHED AND RECOMMENDATION Asurances 7.1 Assurances have been obtained from GOI during negotiations that: (a) (b) (c) (d) (e) consultants for institutional strengthening and training and for construction supervision of Jatiluhur Dam remedial works would be employed by January 15, 1995 (para. 3.9); GOI would submit resettlement plans to the Bank for review and approval for any works requiring the resettlement of people (para. 3.12); vehicles required for the project would be procured from Government budgetary resources under a schedule agreed with the Bank (para. 4.3); all consultants would be selected in accordance with the Bank's Guidelines and engaged according to the Bank's Standard Conditions of Contract for Consultants (para. 4.6); GOI and its agencies would comply with the reporting and auditing requirements specified in para. 4.11; (f) GOI would carry out, every 12 months starting not later than April 1, 1996, technical audits acceptable to the Bank, and send copies of the audit reports to the Bank for review and comments, commencing not later than October 1, 1996; to that end GOI would submit to the Bank for review and comments not later than June 1, 1995, draft terms of reference and proposed organizational arrangements for the performance of technical audits (para. 4.12); (g) (h) GOI would establish, not later than April 1, 1997 a national dam safety regulatory agency with jurisdiction over all dams in Indonesia (para. 5.1); GOI would, not later than May 31, 1995, issue operational guidelines for the Dam Safety Commission and Dam Safety Unit, acceptable to the Bank (para. 5.3);

33 (i) (j) GOI would submit to the Bank for its review and comments: (i) not later than September 30 each year, a work program and cost estimates for the following fiscal year; and (ii) by December 31 each year, budget proposals for the agreed work program, taking into account the Bank's comments (para. 5.6); GOI would submit to the Bank for review and comments not later than March 31, 1998, a proposal for a funding structure for operation of the national dam safety program, by the designated authority, and thereafter prepare and carry out an action plan taking into account the comments by the Bank (para. 5.7). Recommendation 7.2 Subject to the above agreements, the project would be suitable for a loan of US$55.0 million equivalent to the Republic of Indonesia for 20 years, including a grace period of 5 years, at the Bank's standard variable interest rate.

35 ANNEX 1 INDONESIA DAM SAFETY PROJECT BACKGROuND OF DAMs IN INDONEsiA 1. Dams for storing water have been built in Indonesia since the early 1900s, with the older dams primarily serving irrigation schemes. Today there are more than 120 large and numerous small dams and weirs in Indonesia. Of these about 60 are greater than 15 meters in height and are considered to be large dams by the International Commission on Large Dams (ICOLD). Another 60 dams with a height of less than 15 meters have a gross reservoir capacity of at least 500,000 cubic meters. Approximately one-third of the 60 large dams were constructed prior to Almost all of the older dams were earthfill or rockfill and most were single purpose for irrigation. During the post-1970 period however, several multipurpose dams have been constructed. Figure 1 below shows the age distribution of the 60 large dams and illustrates that more than half of the large dams in Indonesia are older that 15 years. Figure 1: Age Distribution of Large Dams in Indonesia D15 U. 0 z TIME IN DECADES (4 DAMS UNDER CONSTRUCTION)

36 ANNEX 1 2. For much of the 1970's Indonesia was the world's largest importer of rice, but by the mid-1980's it had achieved self sufficiency in rice production. Dry season irrigation has significantly contributed to this expanded production and reliable water storage facilities are now critically important for sustaining agricultural production. In addition, the country depends on dams for hydropower production, flood control and municipal and industrial water supplies. With a rapid expansion of the urban population, the need increases for reallocation of water from irrigation to municipal use, as well as expansion of storage capacity to serve all users. The safe condition of the country's dams is of major importance and has been receiving increased attention by the Ministry of Public Works over the past few years. 3. Indonesia has not as yet experienced major dam failures. However, it is acknowledged that the safety status of dams often change over time and frequent checks are needed to confirm their condition. The country is located in a region of active seismicity which contributes to the difficulty of estimating the forces to apply in the original designs and in the assessment an existing dam's stability. It is not uncommon for technical methods of analysis to change with time, based on experiences in other seismic regions, and new criteria should be used. Although the dams are subject to routine surveillance by the operating personnel, there is no formal consistent and comprehensive system of inspection, reporting and evaluation. The valleys downstream of the dams continue to attract additional population and in many river basins, large numbers of people are now exposed to the risk of dam failure. The hazard level below most of the dams has increased over the last two to three decades and this trend will continue in the future. Some dams represented only small hazard levels when initially constructed but are now positioned above considerable property and business development and populations. The combination of increased hazard and the natural tendency for dams to deteriorate structurally with time, results in an increased risk of greater potential loss of life and property due to dam failures. 4. ICOLD has produced international standards for dam safety, guidelines for governig legislation and descriptions of dam safety programs. Indonesia is represented in ICOLD and normally sends representatives to conferences and annual ICOLD meetings. These representatives have become very supportive of a national dam safety program. 5. The larger dams associated with the expansion of hydropower and the large irrigation projects have typically been designed by foreign consulting firms. There is, however, an expanding technical expertise within the country of engineers with technical training and experience of working with foreign engineers on projects with dams. This project targets that base of technical expertise for the selection of staff for the dam safety unit. 6. The following Table 1 presents pertinent data on the location, type, size, function, spillway capacity and ownership of Indonesia's large dams.

44 Detailed Description of Dam Safety Commission Activities ANNEX 2 3. Preparation of Guidelines. The guidelines would be prepared as early as possible and issued by the Minister of Public Works. The guidelines must be sufficiently flexible to allow the DSC to adjust to its role. Elements to be included are: (a) a statement of the charter creating the DSC; (b) a statement of goals and objectives for the DSC; (c) a definition of the DSC's structure; (d) meeting locations and frequency; (e) procedures for administrative support; (f) compensation of DSC members; (g) requirements for attendance; (h) procedures for the conduct of DSC meetings; (i) meeting formats; (j) recurring items to be reported upon by DSU; (k) working relationships with DSU; (1) procedures for reimbursement of expenses; (m) travel procedures and regulations; (n) reporting requirements to the Minister of Public Works; (o) procedures for the adoption of regulations; (p) availability of technical assistance; and (q) availability of legal assistance. 4. Appointment of Members. The proposed membership of the DSC would consist of one person from each of the following agencies or organizations: (a) Ministry of Public Works (DGWRD), (Chairman of DSC); (b) Ministry of Home Affairs (Civil Defense Agency); (c) Ministry of Mining and Energy; (d) Ministry of Industry; (e) Ministry of Environment; (f) State Electricity Corporation PLN (Perusahaan Umum Listrik National); (g) Asahan River Authority (PT Inalum); (h) Indonesian National Committee on Large Dams (INACOLD/KNIBB); (i) Research Institute of Water Resources Development (RIWRD/IHE); () Legal Advisor (Dept. of Justice); (k) Law Enforcement Agency; and (l) Chief, Dam Safety Unit, (Secretary of DSC). 5. The Chairman, members and Secretary of the DSC have been be appointed under a Decree of the Minister of Public Works issued in April The Chief of the Dam Safety Unit will be the permanent secretary of the DSC. In the early stages, the Chairmanship would be held by the Director General of Water Resources Development (DGWRD).

45 ANNEX 2 6. Establishment of Quarterly Meeting and Training Schedules. The DSC members will receive extensive training both in Indonesia and in foreign countries. Training topics will include: (a) (b) (c) (d) the importance of dam safety; the causes and consequences of dam failures; the responsibilities of dam owners, dam safety officials and government officials; public safety considerations; and the elements of an effective dam safety programn; guidance on the requirements and resources necessary to establish an effective dam safety program; the importance of dam maintenance and its relationship to dam safety; the development of dam operations and maintenance procedures necessary to ensure dam safety; and the necessity for dam inspection programs; the critical importance of emergency action plans and the numerous and varied governmental entities involved in the successful development and implementation of such plans; and the procedures involved in the promulgation of dam safety regulations and legislation necessary for the implementation of the national dam safety program; the responsibilities and liabilities inherent in the role of dam owner; and the legal consequences of dam failures. 7. Commencement of Training. Training activities will commence upon establishment of the full DSC membership and will be conducted at periodic intervals in order to orient new DSC members and to keep established DSC members current on the latest dam safety concepts. 8. Review of Dam Safety Unit Activities. The DSC will establish the general guidelines that govern DSU operations and will review DSU activities for compliance with established national dam safety goals; approve proposals from the DSU for regulations and guidelines; provide advice and recommendations to the Minister for Public Works on suggested resource allocation requests developed by the DSU; and, in general, be responsible to the Minister for the achievement of national dam safety goals. 9. Approval of Dam Safety Guidelines Prepared by the Dam Safety Unit. Upon receipt of draft regulations and guidelines from the DSU, the DSC will conduct a complete review to ensure compliance with established dam safety policies. Such review will not only utilize the broad professional experience and knowledge of the DSC members themselves, but may utilize special skills from legal advisers and technical consultants that are made available on an ad-hoc basis to deal with a particular technical issue. 10. Development and Approval of National Dam Safety Regulations (PERMEN) and National Legislation. As the dam safety program develops from the initial start through the integration and incorporation of all darns throughout the nation it will be necessary to draft and implement regulations and legislation at the national level. This process will begin in the DSU with identification of needs that become evident as

46 ANNEX 2 DSU develops its regulatory capacity. These needs may range from establishing technical criteria that are applicable to all dam owners and which will provide uniform standards throughout the country to establishing regulatory criteria which set forth what legal authorities exist to enforce dam safety laws and decrees and what sanctions should be imposed upon dam owners that do not comply with findings of the DSU and/or DSC. 11. Based upon operational experience the Chief, DSU, will draft proposed regulations or legislation. These proposals will be presented to the full Dam Safety Commission with a request for adoption. The DSC will evaluate the proposal and may choose to seek outside technical assistance. The DSC may also conduct hearings or other fact finding activities in order to be more fully advised on the impact and need for the proposed regulations. Along with technical and legal considerations, the DSC will consider economic and environmental impacts and implications of the proposal. Once all relevant facts are considered, the DSC may recommend that the proposed regulations or legislation be enacted as drafted, or amend the proposal to conform more closely with the national interest, or return the proposal to the Chief, DSU, for further evaluation, or simply choose not to proceed with the proposal at the present time. 12. Develop the National Program for Dam Safety Awareness. Due to the high visibility of the DSC and its ability to access the national government at the decisionmaking level, the DSC is uniquely positioned to have a major impact on dam safety awareness. Dams play a very important role in the economic life of Indonesia by providing irrigation water for crop production, water for the industrial sector, electricity generated by hydro-electric facilities and used for private and industrial purposes, drinking water supplies to major cities and towns, flood control benefits, and, recreation opportunities. Yet, dams if left poorly maintained can be serious threats to life and property. These facts must be made known to the general population of Indonesia through a well-planned and executed public awareness program. The DSC, utilizing the technical proficiency of the DSU and by calling upon public relations specialists within the government and the private sector, will develop an integrated national dam safety awareness program that can be used in the school system, the public and private work force and the national media. B. DAM SAFETY UNrr 13. The Dam Safety Unit (DSU) is a regulatory agency and, as such, must remain separated, as much as possible, from dam owner agencies in order to provide an unbiased and objective assessment of the true status of the dams within the jurisdiction of the program. With regulatory responsibility comes enforcement authority. The DSU will be expected to provide the necessary technical evidence that will be the basis for sanctions against dam owners in the event of non-compliance with program mandates. 14. The proposed DSU structure comprises five sections as follows: (a) (b) (c) Field Monitoring and Inspection; Dam Design Review; Data and Records;

47 ANNEX 2 (d) (e) Training Coordination; and Administration. 15. In operational terms, the DSU would adopt a matrix organizational structure with project teams selected for specific duties on the basis of technical requirements of specific tasks. The specific technical capabilities of the DSU staff would be expected to fall within the following main categories: (a) (b) (c) (d) Hydraulics and Hydrology; Geotechnical and Geological Engineering; Mechanical and Electrical Engineering; and Materials and Construction Engineering. Staffing levels are projected to be 16 full-time equivalents during the first 3-4 years of the progran with these levels expanding to approximately 20 full-time equivalents as the programn assumes true national level status and begins to conduct its regulatory role over all jurisdictional dams within Indonesia (see Charts 1 and 2). Summary of Dam Safety Unit Activities 16. The DSU will participate in the following activities: (a) initial establishment of the dam safety progran; (b) development of the dam inventory and records management progrun; (c) preparation of hazard classification and inspection priority; (d) carry out dam safety inspection program; (e) development of dam safety assessments; (f) owner notification of required actions; (g) review and approval of remediation plans; (h) review and approval of final plans and specifications; (i) construction inspection; (j) enforcement actions; (k) development and approval of emergency action plans; (1) preparation of guidelines and procedures; (m) budgeting and programming; (n) reporting; (o) training; and (p) development of a public awareness strategy. Detailed Description of Dam Safety Unit Activities 17. Initial Establishment of the Dam Safety Unit. The DSU must be viewed by dam owners as being extremely competent from a technical standpoint in order to gain the respect of the community that it is expected to regulate. Selection of highly qualified technical personnel who are then provided additional training, in-country as well as overseas, is a key requiremento ensure the necessary level of expertise. A strong sense of technical competence combined with a high 'esprit de corps" will enable the DSU to

48 ANNEX 2 resist the inevitable pressures brought about by vigorous enforcement of the dam safety regulations. 18. Development of the Dam Inventory and Records Management Program. A complete inventory of dams must be conducted nation-wide. This inventory will form the basis for all further actions relating to dam-safety. During the inventory process the physical parameters of the dams will be ascertained, estimates of hazard-classification made, initial assessment of conditions and need for rehabilitation developed, and a priority for comprehensive safety inspections established. The inventory will rely upon dam owners to furnish as much information as is available for each dam and the physical site visit should be conducted jointly by DSU personnel and owner staff. 19. Of parallel importance to the inventory process is the development of a complete records maintenance program that logically catalogs all information pertaining to a particular dam and makes the information readily available. This records maintenance system will consist of computerized data bases as well as hard-copy material that must be preserved. Before each dam safety inspection, the inspection team will review all documents pertaining to the dam that are relevant to the inspection including previous inspection notes and reports. These files are not simply archival in nature but are a dynamic history of each dam that grows and changes with each event that affects the structure itself or creates knowledge about the structure. Photographs should be taken during construction and inventory inspections and included in the record files. 20. Hazard Classification and Priority Listing. To assist in the ranking of dams for inspection and to determine the various technical criteria that are to be applied to dams, it is necessary that a hazard classification be assigned. The hazard classification is developed, predicated upon what results would occur in terms of loss of life and property damage if the reservoir were full and the dam failed under non-storm event conditions. Hazard rating does not refer to the present condition of the dam. 21. Normal hazard classification ratings are as follows: (a) High Hazard: Normally utilized when failure of the structure can reasonably be expected to cause significant loss of life and create severe property damage and economic dislocation. (b) Moderate Hazard: Utilized when failure of the structure is expected to cause minimal loss of life, but substantial property damage. (c) Low Hazard: Assigned to dams whose failure will not cause loss of life and the property damage and economic consequences of failure are small. 22. The hazard classification is a subjective assessment based upon evaluation of the downstream conditions and the determination of the economic consequences of loss of the use of the dam. Hazard classification is the primary indicator of priority for dam safety inspections as well as for allocation of fiscal resources needed for remedial work for the dam.

49 ANNEX Dam Safety Inspection Program. Periodic safety inspections are conducted by DSU experts independently of the inspections performed by the dam owner staff. The dam owner is encouraged to have personnel accompany the DSU staff as a training opportunity and to allow face-to-face communication at the site. The frequency of inspection for each dam is controlled by the hazard classification and the condition of the structure itself. The goal of the dam safety program is to inspect all dams on the inventory at least once every five years but dams in the high hazard category may need to be inspected more frequently. If the dam has certain features that require skills not existent in the DSU, a special consultant will be retained to provide the necessary technical evaluation. During the initial start-up period for the DSU, consultants will be required on all inspections as a way to train the DSU staff and to assess the skill acquisition process of the individual staff members. 24. Development of Dam Safety Assessments. Upon completion of the Report of Inspection, the DSU staff must develop a documented assessment report of all actions required to be taken to bring the dam into compliance with established policies and guidelines. The recommendations must be broadly written so as to allow the owner the flexibility of utilizing all acceptable engineering solutions but must be precise in stating what must be achieved. An implementation schedule must be provided notifying the owner of the latest times that certain activities must be accomplished. The assessment report is forwarded to the Chief, DSU, for his review and concurrence in the findings and recommendations. 25. Owner Notification of Required Actions. Upon completion of the Dam Safety Assessment Report by the DSU, it must be forwarded immediately to the dam owner for implementation. The implementation schedule may be negotiated if the owner can demonstrate cogent reasons that prevent completion of work items on the schedule set out in the report. 26. Review and Approval of Remediation Plans. Upon receipt of the Dam Safety Assessment Report, the owner will develop a comprehensive remediation plan to implement the dam safety measures required. This plan must accompany preliminary designs for structural remediation and will include procedures and schedules to ensure compliance within the time-frame set out in the assessment report. The DSU review remains broadly focused on dam safety goals and objectives and does not dictate how the task will be done. This allows maximum flexibility for the owners to develop innovative and cost-effective solutions. When the DSU determines that the remediation plan meets all relevant dam safety guidelines, written approval is forwarded to the owner authorizing preparation of final designs and specifications and implementation of other remedial actions. 27. Review and Approval of Final Plans and Specifications. The DSU has the responsibility to review and approve all final designs and specifications for work that affects the structural integrity of any jurisdictional dam, whether the work contemplated is remediation of an existing dam or construction of a new one. Standards for review should be established early in the development of the DSU in order to provide dam owners with guidelines within which to operate.

50 -37 - ANNEX Construction Inspection. Construction supervision and inspection is the responsibility of the dam owner but the DSU has the obligation, in its regulatory role, to monitor construction activities. This monitoring role should be performed by members of the DSU that have been involved in the inspection of the dan and in the review and approval of the plans and specifications because of the in-depth knowledge that these staff members possess with respect to the dam. Construction inspection activities performed by the DSU are not continuous in nature but are performed periodically as time and resources permit. Often they are guided by critical construction activities that are important to observe. 29. Enforcement Actions. As a regulatory agency, the DSU will be required to enforce the various regulations that are promulgated by the Darn Safety Commission as well as those which originate from the DSU. Because of this requirement it is very important that the DSU personnel be well qualified in their respective fields of expertise in order to have credibility with owners and with the court as they can be expected to give expert testimony in any action brought against owners. 30. Development and Approval of Emergency Action Plans. Even though the probability of dam failures is usually small, planning is required to: (a) (b) identify conditions that could lead to failure and initiate emergency measures to prevent such failure; and, if this is not possible, identify ways to minimize the extent and effects of such failures. Tlhe operating and mobilizing procedures to be followed upon indication of an impending dam failure or major flood should be carefully predetermined and documented. 31. An Emergency Action Plan (EAP) commensurate with the dam size, location and hazard classification should be formulated for each dam. The plan should require an evaluation of the damage potential created from a postulated dam failure by use of flood inundation maps, should develop a sequential list of emergency actions, coordinated with local civil preparedness and law enforcement officials, and should contain a formal procedure to detect, evaluate and mitigate any potential safety problem. Owners of dams should evaluate the possible modes of failure for each dam, be aware of indicators or precursors of failure for each mode, and consider the possible emergency actions appropriate for each mode and the effects on downstream areas of failure by each mode. Evaluation should recognize the possibility of failure during flood events as well as during normal operating conditions and should provide a basis for emergency planning actions in terms of notification and evacuation procedures where failure would pose a significant danger to human life and property. Plans should be prepared in a degree of detail commensurate with the hazard and instructions should be provided to dam operators and attendants regarding the actions to be taken in an emergency. Planning must be coordinated with local civil defense and police officials to enable those officials to become aware of the catastrophic nature of dam failures and to develop workable plans for notification and evacuation of local communities when conditions threatening dam failure become apparent.

51 ANNEX While development of EAPs is a responsibility of the dam owner, the DSU must provide guidelines for their development and should be available to assist with technical advice during the plan formulation. Once the plan is developed to the satisfaction of the owner, including coordination with local officials, it should be submitted to the DSU for formal approval. 33. Preparation of Guidelines and Procedures. An important aspect of the DSU function will be to prepare guidelines and procedures in support of the various dam safety related activities. These documents are essential in order to provide uniform implementation of dam safety policy and will ensure that the information and procedures established during the development of the national program can be readily reviewed and amended as the dam safety program develops. 34. As a minimum, guidelines covering the following topics will be developed: (a) (b) (c) (d) (e) (f) (g) inspection and reporting guidelines; instrumentation and monitoring guidelines; stability requirements for design loads; operation and maintenance guidelines; emergency action plan guidelines; inflow design flood and seismic criteria; and other technical guidelines and criteria relating to dam design and dam safety. Documentation will include procedures, guidelines, forms of records, reporting form formats and standard forms and checklists as required to enable the DSU to perform its mission. 35. Budgeting and Programming. As the executive arm for the national dam safety program, it will be the responsibility of the DSU to develop a comprehensive annual budget to ensure full implementation of the program. This budget must cover the operational requirements of the DSU staff as well as the needs of the DSU. 36. Reporting. The DSU will be involved in substantial reporting requirements to the DSC to other elements of the Government, to the general public, and to the national and international dam safety community. Periodic reports will be required from the DSU by the DSC in order to allow the DSC to perform its oversight function of the dam safety programn. Budget, personnel, and other administrative reporting will be required of the DSU from the Ministry of Public Works. Additional reports will be necessary to inform the general public of the dam safety assurance program and because of the high level of technical expertise of the DSU staff, technical reports on various technical matters will be of great interest to the consulting and academic communities on both a national and international level. 37. Training. The DSU will be responsible for arranging for, and in some cases conducting, training for the DSC members, dam owners staff, provincial dam safety personnel, DSU's own staff, and consultants. The objective of the training program is to upgrade the expertise of all those involved in dam safety by presenting courses dealing

52 ANNEX 2 with dam safety assurance and organization, dam safety inspections, design aspects of dams including hydrology and geotechnical issues, construction techniques, instrumentation of dams, maintenance and operational aspects of dams, and design and monitoring of dam remedial works. 38. It is essential that a comprehensive long-term training plan be developed that will enable those concerned with dam safety to remain current with accepted technical procedures pertaining to dam safety and to provide training for new personnel entering the arena of dam safety. 39. Development of a Public Awareness Strategy. The DSC is responsible for developing a national dam safety awareness program designed to inform the general population of the importance of dams to the economic well-being of Indonesia and to advise the public of dam safety procedures and activities. The responsibility of the DSU will be to assist the DSC in these activities by providing technical assistance where needed and by conducting training programs that benefit all segments of society. C. DAM MoNIToRING UNITS 40. There is a need to strengthen the owners' capacity to implement the necessary remedial works. The inspections and evaluations of the DSU would identify the items that are deficient and it then becomes the owners' responsibility to respond. MPW agencies need more capacity to carry out the surveys, investigations, designs of remedial works, contract administration and construction supervision. A proposed new Subdirectorate of Large Structures would be in charge of implementing the remedial works program for MPW dams. In addition, a central Dam Monitoring Unit (DMU) to be located in this subdirectorate, and a number of provincial DMUs, would assist in coordinating the initial inventory of MPW dams, gathering data, selecting basic safety facilities and collecting and evaluating field monitoring information. After the project is completed, this monitoring activity will continue under the direction of the central DMU. 41. For the duration of the implementation period of this project, the Head of the proposed new Subdirectorate of Large Structures would be the Project Manager. This person would direct the entire range of activities from establishing the dam safety institutions, arranging for dam inspections and evaluations, to the implementation of the remedial works program. The Project Manager would also direct the procurement of associated equipment for the project and be the primary contact person with the Bank. The DSU on the regulatory side would be separate organizationally from the proposed new Subdirectorate of Large Structures charged with handling of construction and maintenance. The Subdirectorate of Large Structures would be responsible for construction of new dam projects as well as implementation of remedial works on existing dams. The proposed organizational arrangements are shown in Charts 1 and The proposed new Subdirectorate of Large Structures would be responsible for environmental screening of dams, and for preparation of Environmental Impact Assessments, Environmental Action Plans and Resettlement Plans, should they be required.

53 ANNEX 3 INDONESIA DAM SAFETY PROJECr TRAINING 1. The objective of the proposed training program is to develop a high level of expertise in the dam safety institutions (DSC and DSU) and to upgrade the expertise of Ministry of Public Works and other dam owners' staff capability in dam safety assurance matters. Training of the members of the DSC and the staff of the DSU and the dam owners is considered to be of fundamental importance both in terms of the immediate requirement for inspection and safety assessments of dams and in terms of the programs' long-term sustainability. The strategy, approach and methodology proposed for the training program include extensive over-seas and in-country training, broad coverage of all technical disciplines in a class-room environment, and extensive hands-on field experiences guided by experienced international consultants. Training topics include dam safety inspections, design aspects of dams (structural, hydrologic and hydraulic), construction techniques, instrumentation, and design and monitoring of dam remedial works. 2. Technology for design, construction and inspection of dams continues to develop. Staff engaged in dam safety matters must be educated in new techniques and trained in their use as an on-going activity. The strategic aim of the proposed training program, therefore, is to promote a shift from dependency on external expertise across the range of dam inspection, surveillance and operation and maintenance activities to a position of greater self-sufficiency and capability of MPW staff to address the longer term needs of the dam safety program. The selection and retention of skilled individuals is the most critical factor in the successful implementation of this strategy. 3. The key elements of the training program will include the following topics: (a) (b) (c) (d) (e) (f) (g) (h) (i) (j) (k) dam safety program establishment, including the organization, function and responsibilities of the DSC, DSU and DMUs; inventory, registration and hazard classification; detailed site inspections; stability evaluations; hydrologic assessment and evaluation of flood handling capability; dam design and construction; dam rehabilitation; emergency action planning; operation, maintenance and surveillance; environmental screening; and resettlement plans.

54 - 41- ANNEX 3 The consultants for institutional strengthening and training will prepare and arrange for the delivery of the training programs. 4. Figure 1 presents the timeframe for conducting the key training activities. This includes the more formal courses, seminars and study tours, and also includes the element of on-the-job training. The on-the-job training will be provided by working alongside the consultant team. Table 1 indicates the approximate number of recipients and their organizations, who will be trained over the course of the project.

57 ANNEX 4 INDONESIA DAM SAFETY PROJECT BASIC DAM SAFErY FACIxITIES 1. Many of the older dams in Indonesia were not originally equipped with features that are now considered indispensable. In addition, after long use with minimal maintenance and care, there is frequently very little left of the original records and drawings that define the dam's physical characteristics. In other cases, erosion, wear and tear, and deterioration of portions of dams have modified the basic conditions of the dam over the years. An assessment will be made of missing basic facilities and basic data of the dam and appurtenances early in the project period. A program will then be initiated to add these basic facilities and to gather the technical data prior to the more formal safety inspections and design of remedial work. Most common deficiencies are measuring devices and instrumentation, communications equipment, back-up operations equipment, the original drawings of the dam, and records of past physical modifications. The needs for each dam will vary and it will require a process of careful inventory, prioritization and allocation of funds to implement this component of the project. The objective is to start with the activities which can reduce the risk of dam failure, prior to the time more extensive remedial works can be carried out. In some cases the addition of the basic safety facilities may be the only action required for an existing dam. 2. Early in the project period, one of the primary activities will be the overall inventory of dams throughout the country. This inventory will be conducted under the direction of the Dam Safety Unit (DSU) in close cooperation with the Dam Monitoring Unit (DMU), the operations staff at each dam and the consultants. The inventory will involve a visit to each dam and collection of as much information as possible on the dam's physical features from the existing operating personnel at the dam site. These inventory inspections will not make a full evaluation of the dam's safety status but will determine the additional information needed, and will outline the basic facilities needed for future detailed inspections and evaluations. 3. Once the inventory process is nearly complete, the DSU and DMUs will consult to determine the priority of sites to receive the basic safety facilities and to outline a program for implementation. The new Subdirectorate of Large Structures will be in charge of implementing the program and may use a series of consultancy contracts to assist in this process. These facilities should be in place and the data collection initiated prior to the formal inspection by the DSU. Any additional facilities that may be required would be included in the subsequent dam remedial work for the inspected dam. The Dam Safety Unit will also give the dam operations and maintenance staff advice and guidance on monitoring and protection of the instrumentation or equipment provided.

58 ANNEX 4 4. The basic dam safety facilities are broadly defined as items that assist the operation and maintenance personnel at the dam to assess emergency situations and to respond with timely actions that can often mean the difference between failure or saving a dam. One of the more critical aspects of most dams is to be able to monitor and control the flow releases during a major flood. Thus equipment that can assure that the operator has access to information at this time and can quickly respond is important. Reservoir level markers, data on the storage volume for every increment of reservoir rise, backup operator devices such as handwheels, gate motor operators, standby power supplies for flood gates, and communications equipment to allow those at the site to report and coordinate critical actions during flood operations. 5. Another type of basic facilities is adequate instrumentation for monitoring the dam's performance. The most common items needed to be measured at a dam are the seepage and main dam section movement or settlement. Sudden changes in these two elements are very positive indicators that something is happening to the dam that requires either investigation or remedial action. During the inspection for the inventory, an assessment will be made of the instrumentation for seepage flow measurements. Probable measuring points and size of the measuring devise will be noted. In larger earth embankments, peizometers may be needed to measure hydrostatic pressures within the embankment at various locations. These will be noted and added under basic safety facilities. A system for establishing an elevation control and measuring the dam settlements, crest erosion or structural deformation will often be required. In some cases it may be practical to install this only after remedial work is performed if such remedial work requires major additions or raising of the embankment sections. In all cases the furnishing and installation of these additional measuring devices will be provided if they do not presently exist in the dams. 6. Table 1 of this Annex presents a categorization of the types of equipment and actions that would be provided under this component of work. It is estimated that basic facilities would be provided, or additional survey and data gathering performed, for about 60 percent of the dams within the project period.

61 -47- ANNEX 5 INDONESIA DAM SAFETY PROJECT REMEDIAL WORKS Nature of Works 1. Many of the dams in Indonesia have not received the needed level of maintenance and care to keep the facilities in top working and safety conditions. With water resources utilization and management becoming more vital to the future development of the country, it is imperative that the country's dams be made safe and upgraded to provide continued service. The process of inventory and prioritization of the inspection and evaluation program by the Dam Safety Unit will be dependent on the hazard classification and the initially noted deficiencies. There may be a number of dams which have been neglected in regard to maintenance but still are stable and effective in their function. While lack of maintenance will eventually weaken a dam's performance capability, it may still pose only a small risk from the standpoint of dam safety. The project purpose is not to rehabilitate all dams to their original condition but to assess their safety and assure they do not present a high public risk due to their condition. It will be difficult to separate items of work on the dams between what is rehabilitative and what is remedial for the purpose of safety. 2. The remedial work to upgrade dams for safety reasons most commonly involve their structural elements or their capability to safely pass the appropriate flood events. The proper functioning of control valves and other electrical and mechanical equipment is also important as is the capability of the dam operation and maintenance staff to know the physical condition of their dam at all times. The nature of the remedial work to be performed under the project will vary considerably from dam to dam and the specific design is determined only after detailed investigations, analysis and evaluation by competent dam engineers. The project therefore includes a provision for consultant services in regard to detailed surveys, field investigations (and possible field exploration and materials testing), and professional dam engineering analysis. The preparation of the remedial designs is often as difficult as the preparation of the original dam design. In some cases the technical analysis may require the services of highly specialized dam engineers, available only from foreign sources. It is therefore expected that foreign engineers, local engineers and in-house MPW staff will all participate in preparation of remedial works designs and contract documentation preparation. Implementation 3. Implementation of the remedial works component may take a variety of forms. The most common will be to prepare a civil works type contract and solicit bids from firms with the capacity and experience to carry out the remedial work. This will

62 ANNEX 5 require professional construction supervision by DGWRD and in most cases close cooperation with the dam operations staff. In addition the continuing operational requirements of the dam often limits or restricts the actions that can be taken or requires the remedial work to be spread over a longer time period to avoid serious disruption of water deliveries. On the construction side there is the possibility that the maintenance crews can implement some of the desired work. Under this project the general dam safety consultant will need to provide guidance to the Subdirectorate of Large Structures in determining how each remedial work should be carried out. There will also be situations where the survey, investigations and designs for three to five dams might be contracted to one consultant. In other cases the work may be highly complex and of a high level of importance and thus require the services of an experienced international consultant firm. Readiness for Implementation 4. The most prominent dam to receive remedial action is the Jatiluhur Dam which is located on the Citarum River, approximately 150 kilometers upstream of Jakarta. All other dams have been placed in categories by degree of readiness for implementation of remedial works (Categories A, B, and C). Remedial works for Jatiluhur and 11 other dams have been designed. These 'Category A" dams are the following: Cacaban Malayahu Penjalin Nglangon Darma Ngancar Cengklik Greneng Simo Batok Sanggeh It is expected that the remedial works for these dams could be tendered and placed under contract within the first six months of the project. Construction periods will be different for each but the average time for completion after start of work is estimated to be approximately nine months. Due to these dams having near final designs backed by field surveys, a physical contingency factor of 10 percent has been applied to the cost estimates. For Jatiluhur Dam, the main contract for the strengthened rockfill section has been prepared following detailed surveys and estimates, thus a 5 percent physical contingency factor was used in the cost estimate. For the two other contracts at Jatiluhur, a 10 percent factor was employed. 5. In April-June 1992, 25 dams were inspected by the project preparation consultant team. Ten of those dams were deemed to be in need of remedial work in advance of the others and conceptual designs were outlined and rough cost estimates prepared. Additional investigations and design work will be needed at such sites. The following dams have been placed in 'Category B" in regard to the degree of readiness: Gembong Krisak Batujai Pacal Gondang Ketro Klego Embung Bringe Sampean Baru Setu Patok

63 -49- ANNEX 5 Due to the need for more investigations and designs for these dams, a 15 percent physical contingency factor was used in the cost estimates. It is estimated that four of these dams could be investigated, surveyed, designed and remedial works performed within a year of project initiation. The other six are estimated to require two years for complete implementation. The location of the Category A and B dams is shown in Map attached to this report. 6. About 70 dams have been classified as 'Category C" dams. Some 20 ICOLD dams are included in this category. Subject to inspection, investigation and completion of design, required remedial works would be undertaken from FY1996/97 through FY 1999/2000. Land Acquisition and Resettlement 7. The remedial works are not expected to necessitate the acquisition of addidonal land for new rights-of-way, and therefore the issue of resettlement of people is not expected to arise. No additional land is required for Jatiluhur or any of the Category A dams for which works designs have been completed. 8. Should land be needed for any of the Category B and C dams, a plan would be prepared in accordance with the following requirements to be agreed at negotiations: (a) (b) (c) (d) (e) (f) Remedial works will be designed in a manner which will help minimize displacement and adverse effect on incomes of affected people. All remedial works requiring resettlement/relocation will provide for appropriate compensation for assets based on market value (including logistical support for moving, and relocation as required). Action plans will provide for all measures and compensation required to restore the standard of living of all affected people, as fairly and equally as possible, whether their land rights are customary or formal. Preparation of these action plans will be based, inter alia, on consultation of affected people, surveys of land titles and ownership of dwellings and of affected residents. The action plans will have a clear implementation timeframe and construction works will not start within or adjacent to the relocation area before required resettlement has been completed. The process will be transparent. Information relating to the people affected, the compensation they are entitled to, the available options or alternatives and the grievance and appeals procedures will be provided by the project manager and made readily available to the executing agency and the Bank.

64 ANNEX 5 (g) (h) The action plans will specify the organizational responsibilities for implementation and supervision and measures needed to strengthen the capabilities of agencies involved in accordance with the requirements of the prevailing GOI laws and regulations. The final cost estimates will include all costs required for the satisfactory implementation, and the management and monitoring of the land acquisition and resettlement/relocation plans and Bank approval will be subject to all necessary funds having been budgeted for. 9. With regard to the question of appropriate compensation based on market value [item (b) above], before developing methodologies to be used for establishing market value of properties, DGWRD will seek relevant information from the Bureau of Statistics, the taxation authorities and the Land Agency, and will exchange views with the Bank on the findings and proposals developed based on these findings.
