II. Suggestions, Inputs, and Evaluations from Technical Team and EIA Evaluation

Team, Jakarta Capital Region Provincial Environmental Impact Assessment Evaluation Commission

1. Meeting Chair

a. The public should proactively provide information if environmental management is not carried out by the proponent for the JEDI Project river dredging.

2. Drs. Ramdhani

a) Will there be an effort to empower the local residents by including them in the dredging activities?

b) How will the post operational management be carried out, is there a Guiding Conceptual Framework for this?

c) Technical Methodology in the EIA Document page III-58, Tables 3.24 and 3.25, need to be examined within Resource Formulation, because the community needs to be involved.

d) Environmental Management and Monitoring Plans, page III-20, the need to have Resident-Observers/Inspectors, this needs to be organized so that it is clear in

the documents and the application of it must be accessible to the residents. Within the EIA document there are lines of control, but where are the functional lines?

e) Basic duties and functions of the Community Relations organization need to be established.

3. Dr. Supardio

a) Processes in the operational stage are extremely important, in connection with the Standard Operating Procedures of the activities.

b) Specific information is needed on the activities with creation of dredging SOPs. c) The Disposal Area is extremely important; ensure that continued impacts don’t

arise. d) Attention must be paid to sanitation issues. e) Implementation of the Environmental Management and Monitoring Plans must

be carried out consistently, for example the cleaning of sediments must be carried out routinely.

f) Post-operational management. g) A complaints coordination post is needed.

4. Drs. Ridwan Panjaitan, MSci

a) Activity components should be explained clearly (area, width, volume of sediment) for individual sites. There needs to be a clarification on temporary dumping sites.

b) Ensure there is a Center for Community Complaints established for each site. If there are problems, one must go to whom?

c) Page III-3 shows impacts, but their management is not clear. Where is the matrix of responsibility for impacts?

d) Environmental Management and Monitoring need to be more technically operational, for example for the temporary dumping sites, transportation, turbidity, etc.

e) The organization for implementing environmental management in the construction and operational stages must be clarified among the Directorate General of Human Settlements, Jakarta Public Works, and the Contractor. This needs to be clearly assigned and calibrated within the Organizational Structure. Who is responsible for environmental management?

f) Scope of responsibilities for management/monitoring is where? Does it reach to Ancol? The Environmental Management and Monitoring Plans need to be carried out consistently.

g) Environmental Management and Monitoring needs to be specific (see items 3, 5, and 7 in the Matrix) with respect to traffic, air quality, and sanitation. Don’t generalize it, it is important to be specific.

h) Community input should become part of the research study, and of the environmental management/monitoring.

5. North Rawa Badak Neighborhood Council

a) Next to Rawa Badak Detention Basin, there is vacant land, which could benefit from sediment placement.

b) When will Kapuk and Rawa Badak be dredged?

6. Abdul Rohim (Kartini Neighborhood Council) a) Please carry out real coordination and socialization. b) When will the operational stage socialization be carried out? c) Starting when will recruitment be carried out?

7. Simanjutak (Kapuk Neighborhood Council)

a) How about if there is a community inspection/oversight mechanism, encompassing the block, street, neighborhood, and civil society? This needs to be clarified and the mechanism formed. What about an MOU?

b) The organization responsible for environmental management (Directing Body), should be on standby at the project sites.

8. Drs. Ardian Prahara

a) Manage spills of soil, so that they don’t disturb traffic and [cause] accidents b) Who will be responsible if accidents are a consequence of dredging impacts? c) To accommodate leachate in Ancol, please coordinate with the management

of Ancol.

10.(sic) Drs. Irianto a) Please be really careful in implementation, particularly in establishing a

complaints/grievance mechanism, will this be implemented or not? b) During dredging and transport, please pay attention so that fouling of the

road bed doesn’t occur. c) For the river channel from Gunung Sahari to Ancol, there is extremely dense

traffic, please be careful in transporting sediment, and it is suggested this be done at night.

11. North Jakarta Neighborhood Council

a) Socialization b) We request that the Neighborhood Council be the oversight body to

represent the community. c) Please have a Coordination Post, and station people responsible for

community complaints. d) Public Works should plan the setback distance of residential buildings from

the river channel at approximately 30 meters, to protect the water quality and conserve the river.

12. Regional Water Supply Company Operator AETRA

a) To prevent interference and possible destruction of buried utility water distribution pipes that cross the rivers at the project work sites, it is best to carry out technical coordination in advance between the proponent/contractor and the Regional Water Supply Company (AETRA/PALYJA), because a pipe break will have a direct and destructive impact on the community, both in the vicinity of the site and at other locations.

b) There needs to be a Post Office Box for complaints from the community to anticipate and assist any residents who want to submit complaints.

13. Department of Public Works Response (Bambang Sigit)

a) The dredging activities will be an effort to control flooding, with the methods of; - Empowering the community - Installing disposal bins along the channels/rivers - Implementing solid waste management with the principles of selectivity, inclusion, and concern for the community.

b) The reasons for selecting these five (Phase 1) locations for the JEDI Project are, among others: - Social aspects are not particularly significant - Technical aspects can be implemented.

c) We will form a functional body for community complaints. d) Design planning is being conducted simultaneously with the EIA. e) Contractors will be instructed to establish staffed environmental

management posts.

13. Ir. Hesti D. Nawangsidi, MSP

1. Generally, AMDAL for dredging of river and canal in DKI Jakarta Phase 1, prepared by PT ERM Indonesia with the proponent Directorate general of Water Resource, MPW needs revision that focuses on the following:- In the TOR of the AMDAL (KA - ANDAL), it was agreed that the

AMDAL study will only assess relevant aspect and component. Assessment that has been carried out has not yet been contextual, the study needs to include more detail information and assessment on the dredging and transportation impact. The assessment also needs to be structured to exclude information that is not relevant or necessary.

- The purpose of ANDAL, RKL, and RPL is to support the proponent in carrying out the project, thus the documents produced by the consultants needs to be more practical.

- Impact prediction which is the main part of the AMDAL has not fully included available data and information, more on qualitative assessment based on common sense, therefore not detailed enough information is generated, e.g. what, how, how significant and where the impact will occur. Impact prediction can use analogy approach or logical assumption in case data and information are minimum.

- Environmental management plan should be more practical, considering the urgency of the project.

- Consultant needs to dig out more details data and information related to this project, considering that such source of data is very likely available DKI Jakarta.

- Consultant needs to structure the assessment more integrated and focus, so that the information presented in the document is not such collection of description of environmental component and aspect but should be result of consistent analytical and synthesis process

Assessment has been focused on dredging and only relevant activity

Information in the ANDAL, RKL, RPL has been revised, and now is more practical

Quantitative impact prediction has been included

RKL has been revised

Project description and environmental baseline has been revised

2. If there is no alternative (of the activity) to be assessed, the study should not force to include such alternative (Hal. II-19), in which in the following chapters does not provide further description and assessment of the alternative such as location of dredging, method of dredging and transportation, no-project alternative

Based on guideline of AMDAL preparation (PermenLH No. 08 /2006), the proponent should include project alternative. In the document, proponent has mentioned that there is no project alternative except those provided in the document

II-21

3. The environmental baseline has not provided information on condition and characteristic of the environment relevant to the dredging and material transport such as :- Component on spatial planning (Hal III.1 s/d III.3) has not provided

information on land use plan of the 13 rivers (catchment) following dredging.

- Component on hydrology is one of the most important in this study, generally has been included in sub-section of spatial planning but not detailed enough. Hydrology assessment need to behavior of the flood from time to time, location, size (of flooding area), and duration of the flood; changing of pattern (or return period), cause of floods (change is rain pattern, river slope, sedimentation, land subsidence, high tide (rob), occupation of the river embankment, and garbage load etc.); and effort that has been taken.

- Sub chapter 3.1.2 on system of flood mitigation at municipal level (Hal. III-5 s/d III.7) does not explain the flood mitigation itself but more on wastewater and garbage.

- Component on rain fall (Hal III-7 s/d III-8) does not provide enough information on the pattern and intensity of rainfall that is supposed to be one of important factor in this AMDAL study. Secondary data on rainfall at upper Citarum river catchment area and DKI Jakarta are likely available to support better analysis of this component.

- If the air quality will be affected along the dredged material transportation corridor, then baseline study to describe the current condition should be collected along the corridor (Hal III-10 s/d III-11).

- Explanation on topography and morphology (Hal III-13) should relate to the surface water flow, thus can explain the condition of DKI Jakarta

Land use plan of the surrounding after dredging has been included

Information on hydrology/drainage has been added into ANDAL

Sub chapter 3.1.2 has been revised

Air quality and odor along the corridor has been measured

Has been revised

that is prone to flooding.- Explanation on terrestrial fauna is too much and unnecessary (Hal III-

20). If not relevant, should be excluded.- Explanation of religion and praying facilities(Hal III-28 s/d III-29) is

not relevant.- Component of social and culture (Hal III-33 s/d III.34) is not relevant

The alternative study in Andal: remove, since there will not be further analysis within the next chapter.

Alternative study has been removed

2. Andal Chapter 2 After d) Dredging: Waste Segregation. Add as following: After the dredging, then waste segregation has to be carried out, dredged material is disposed in Bantar Gebang Final Disposal Site, sediment is disposed to West Ancol. The odor will be occurred if segregated waste is not immediately handled.

It has been included into Andal document ANDAL Sub Chapter 2.2.2.2 point e), page II-18

3. Andal Sub Chapter 5.2.2.3

Add dredged waste according to impact prediction matrix. Solid waste impact has been included into impact prediction.

ANDAL, page V-5

4. Andal Page III-12 The term ‘rainfall condition’ is incorrect, it should be ‘rainfall data’, it shows significant difference between wet and dry season. Such kind of information is important as an input for selection of dredging time, within dry seasons.

The term has been revised. ANDAL, page III-12

5. Andal Page V-3 The impact on the city infrastructure, especially related to the presence of drinking water pipes belong to PAM Jaya/AERTA/Palyja lie above the river, should be predicted.

The impact on drinking water pipes lie above the project location has been included.

ANDAL, Sub-Chapter 5.2.2.3 point b.1, page V-5

6. Andal Chapter V Impact prediction is better to be strengthened by environmental baseline data

For instance on page V-4: Impact on Noise and Odor. The baseline data shows that noise level has exceeded the quality standard, whereas odor level is below the quality standard (page III-16). Such data should be the background information for impact prediction.

Another example on page V-4 Impact on Surface Water Quality. The baseline data shows that the parameters which have exceeded the quality standard are COD, BOD, oil and grease, detergent, and organic compound, whereas TSS has not (data shows that the concentration is extremely below the quality standard).

Another example on Andal page V-5: Dredging Impact on People Perception. The data shows that 98.6% of the respondents have positive perception (page III-42) and if any concerns, it’s related to the unclean environment (45%). Therefore, on the impact prediction on page V-5 it should be related to such concern, not about noise.

- Impact prediction can be quantitatively analyzed by looking at the baseline data, and environment change predictions have been delivered in the document.

- The document has been corrected.

CHAPTER I INTRODUCTION

1.1 BACKGROUND

Greater Jakarta is the political and economic center of Indonesia, with an estimated population of over 24 million. The city, with a population of about 9 million, is administered by the Provincial Government of Jakarta (Daerah Khusus Ibukota or DKI). The DKI lies in the delta of the Ciliwung River and about 40% of its area is below sea level. Every year, large parts of the city are flooded during rainy season, from November to April.

The magnitude of the impacts caused by annual flooding in the Capital City has become a national issue due to the large financial losses and the impact on communities in the Jakarta area. To reduce the magnitude of the losses and damage caused by the floods, the Government of Indonesia has identified a series of flood control drainage canals, floodways and retention basins (waduks) that require urgent improvements. The rehabilitation of these structures will reduce the risk of flooding and bring direct benefits to the more than one million people who live and work in the areas prone to flooding.

The Indonesian Government has requested a loan from the World Bank to finance the dredging and rehabilitation of the majority of the existing drainage system in Jakarta. One of the proposed projects is the Jakarta Emergency Dredging Initiative (JEDI) as included in the Jakarta Urgent Flood Mitigation Project (JUFMP), which aims to reduce sediment deposits in flood channels. These sediment deposits have reduced the design capacity of the drainage canals, floodways and waduks by half.

One of the JEDI Project activities is the dredging of 16 drainage structures. The project proponents, the Directorate General of Cipta Karya (DGCK) and the Directorate General of Water Resources (DGWR, Sumber Daya Air = SDA) Department of Public Works (Departemen Pekerjaan Umum = DPU), and DKI Jakarta Government, have responsibility for:

1. Three drainage canals of national importance under DGCK authority: (i) Tanjungan, (ii) Lower Angke, and (iii) Cideng-Thamrin.

2. Three floodways under DGWR authority: (i) Cengkareng, (ii) West Banjir; and (iii) Sunter.

3. Five drainage canals under DKI authority: (i) Ciliwung-Gunung Sahari, (ii) Sentiong-Sunter, (iii) Grogol-Sekretaris, (iv) Pakin-Kali Besar-Jelakeng, and (v) Krukut-Cideng.


I-2

4. Five retention basins (waduks) under DKI authority: (i) Pluit, (ii) North Sunter, (iii) South Sunter, (iv) East Sunter III, and (v) Melati.

For Phase 1 of the JEDI Project, 5 (five) drainage canals/floodways and one waduk have been selected to assess the planning, technical design, and environmental management approach to be implemented in all project sites. These sites have been selected because they are expected to produce relatively small environmental and social impacts but still achieve one of the project activity’s main objectives, and significantly beneficial towards the flood prevention efforts. The sites included in Phase 1 of the JEDI Project (Map I-1) are:

1. Cengkareng Floodway.

2. Ciliwung - Gunung Sahari Drainage Canal.

3. Sentiong – Sunter Drainage Canal.

4. Sunter Floodway.

5. Waduk Melati.

Considering that the dredging activities will have positive and negative impacts to physico-chemical, biological, socio-economic, socio-cultural and public health components, an Environmental Impact Assessment is required for this project (Analisis Mengenai Dampak Lingkungan Hidup , hereafter referred to as AMDAL).

The preparation of AMDAL documents adheres to the requirements of the Environmental Management Act No. 23/1997, specifically Article 15 on the AMDAL requirement for any activity or project with potential significant environmental impacts. In response to this law, the Indonesian Government enacts a Government Regulation (Peraturan Pemerintah) No. 27/1999 regarding process to conduct AMDAL. Furthermore, the Ministry of Environment (MoE) Decree No. 11/2006 lists specific activities that require AMDAL and the MoE Decree No. 8/2006 provides guidelines for AMDAL process. During the course of this project, the Environmental Management Act has been replaced by Environmental Protection and Management Act No. 32/2009 (relevant articles are 22-32). However, subsequent regulations to implement the Act No. 32/2009 have not been published. Therefore, the regulations adhered to in this study still refer to the Act No. 23/1997.

In relation to the dredging works, MoE Decree No. 11/2006 specifies that any maintenance dredging activity in a city area will require an AMDAL if the dredged volume exceed 500,000 m3. The requirement is in line with the regional law (i.e. Governor of Jakarta Decree No. 2863/2001 on type and list of specific business and activities in Jakarta that require an AMDAL. The Decree states that any dredging activities with a volume more than 50,000 m3 must have an AMDAL. The anticipated volume of dredged materials from Phase 1 JEDI Project is 2,080,000 m3.

The AMDAL documents have been prepared based on MoE Decree No. 8/2006 on Guidance on AMDAL preparation, and the AMDAL Terms of


I-3

Reference Dredging of Floodways/Drainage Canals and Waduks Phase 1 (JUFMP/JEDI) approved by DKI Jakarta AMDAL Evaluation Committee based on Decision Letter No. 48/KA/-1774.151 on 9 November 2009. To date, the project activities have not started.

1.2 PURPOSES AND BENEFITS OF THE PROJECT

1.2.1 Purposes

The purposes of the projects are to: (i) increase the capacity of JEDI Phase 1 floodways, drainage canals and waduk through dredging work, (ii) minimize the impacts of annual flooding in DKI through the prioritization on rehabilitation and dredging of existing floodways, drainage canals and waduks, and (ii) provide technical expertise through the on-the-job training that strengthen the capacity of DKI and DPU to operate and maintain the flood control system, in accordance with international standards.

The dredging activity Phase 1 is the preparation of the project, and will test the design technique of removing sediment deposits, transport and disposal of the dredged material, also monitoring and managing the anticipated environmental impacts.

1.2.2 Benefits of the Project

The main benefit of Phase 1 dredging activity is to reduce the extent of loss caused by annual flooding in the most highly populated areas in West Jakarta, Central Jakarta and North Jakarta. Other benefit is the rehabilitation of the overall function of the drainage system.

1.3 APPLICABLE ENVIRONMENTAL LAWS AND REGULATIONS

Applicable environmental policies, laws and regulations used as the bases of the preparation of this AMDAL are listed in Table I-1.

2.2 PROJECT DESCRIPTION

Based on Western Java Environmental Management Program (WJEMP) studies DKI 3-81 and centre 3-102, floodways, drainage canals and waduks (including drains and pumping stations) are in urgent need of rehabilitation through dredging and embankment works. Dredging activities will remove sediment that has occupied half of the designed capacity and reduced operational design from 25 to 2 years. In addition to dredging, improvement works on embankments and pumps are necessary. In 2004, surveys of the four major floodways indicated high levels of sedimentation and found urgent need to rehabilitate parts of embankment. In a number of places, embankment crest levels need to be raised to retain floodwaters. In other places, watercourses should be normalized, or embankments should be strengthened to prevent soil erosion entering the newly-dredged channels.

II-3

Phase 1 of JEDI is a pilot project to minimize the impacts of annual flooding in DKI and to restore the design capacity of the existing floodways, drainage canals and waduks. The Phase 1 will concentrate on 4 (four) selected floodways/rivers/drainage canals and 1 (one) waduk, in Jakarta area, whereby the dredged materials will be disposed of in a designated disposal area. The locations are:

• Floodways under DGWR: (i) Cengkareng Drain, and (ii) Sunter (lower section).

• Drainage canals under DPU DKI Jakarta: (i) Ciliwung-Gunung Sahari, (ii) Sentiong-Sunter.

• Retention basin (waduk) under DPU DKI Jakarta: (i) Waduk Melati.

Dredging activities will include dredging of the sediment, transport to the disposal site and disposal of the dredged material. Dredging activities implemented in various locations will have different types and/or size of dredging equipment due to the wide variety of conditions presented by this project.

Constraints that might affect the process and the selection of dredging method are the number of bridges crossing over each floodway and drainage canals. Based on inventory result, the total number of bridges which affect the project locations is shown on Table II-2.

Essentially, dredging is an act of excavating submerged or saturated sediment from one location and transporting it to another location. There are two main categories of dredging method (i.e. mechanical and hydraulic) with various configurations of each - from dredging the sediment from the bottom of the canal, and transporting the sediment to the disposal site. The following is a brief description of each dredging method:

• Mechanical Dredging:

Mechanical dredging generally uses type of bucket for the excavation of the under water sediment and bringing the sediment to the surface. Mechanical dredges are generally rated by the size of their bucket and can range from less than 1 m3 to greater than 40 m3. This method can excavate most types of material with the exception of the most cohesive consolidated sediments, coral, and rock. Figure II-1 shows a backhoe on a floating pontoon, used to dredge Jakarta’s canals under contract of DKI Jakarta. Figure II-2 shows a crane with clamshell bucket to remove waste from Lower Angke Canal. This type of equipment could be, in appropriate conditions, used for mechanical dredging to excavate material from the bottom of the canal. Mechanical dredges dump the bucket load within swing radius directly into a floating barge, or into a truck for haulage to the disposal site.


II-5

Figure II-1 Mechanical Dredging: Backhoe

A special type of mechanical dredging often used in the smaller urban canals is the floating bulldozer. Figure II-3 shows a floating bulldozer working in Jakarta. The floating bulldozer pushes the mud towards a land based excavator, which takes the sediment out of the canal and puts it in a dump truck.

• Hydraulic Dredging:

The most common hydraulic method is a centrifugal pump to create water flow that erodes and entrains sediment into slurry (water and sediment mixture). Hydraulic pipeline dredges are rated by the size of their discharge pipeline diameter and generally can range from 200 to 1000 mm. Sub-classes of pipeline dredges are defined by the mechanical and/or hydraulic attachments used to loosen and convey the materials at the bottom into the suction mouth. Plain suction dredges have no attachments on the suction mouth, while cutter suction dredges use a rotating array of cutters over the suction mouth, as shown in Figure II-4.


II-6

Figure II-2 Mechanical Dredging: Crane-Mounted Clamshell Bucket Removing Waste

Figure II-3 Mechanical Dredging: Floating Bulldozer


II-7

Cutter suction dredges (Figure II-4) are typically comprised of a hull, main pump and engine, ladder, suction pipe, cutter head, spuds, and hoisting and hauling equipment. The cutter head rotates to dislodge material from the bottom and water flowing into the suction mouth conveys sediment into the suction pipe. After flowing up the suction pipe and through the pump, the dredged material flows through a discharge pipeline to the placement site.

Figure II-4 Hydraulic Dredging: Portable Cutter Suction Dredge

For dredging the floodways, drainage canals and waduk of the JEDI Phase 1 project, most likely only mechanical dredging techniques will be used, considering the condition of the canals and waduk, and the sediment to be dredged.

2.2.2 Project Phase

Dredging works of floodways/drainage canals/waduk in DKI Jakarta will be divided into 3 (three) phases, i.e. pre-operations, operations and post-operations. Descriptions of each phase are as follows:

2.2.2.1 Pre-operations

In this phase, activities will cover:

a) Technical Design

This AMDAL report is written while the technical design of the dredging works is still ongoing. Therefore it might be necessary during the AMDAL procedure to adapt the report based on new, progressing information received from the technical design team.

b) Consultation

Public consultation involving affected communities, private and non-governmental institutions were undertaken on 19 August, 16 September and 29 December 2009. More details information on the public consultation is provided in Section 4.1.1.2 (Public Consultation) and Appendix 1.

2.2.2.2 Operations

In this phase, activities will cover:

a) Workers Mobilization

In the operational dredging activity, there will be approximately 31-41 persons required for each location. Staff, both from contractor or sub-contractor, does not stay in the project locations and they mobilize every day, while daily workers stay in a base camp on/around the project locations. Details of workers needed, can be seen in Table II-5.

Hiring process for dredging activities will be done by contractors, and will involve local resources if qualifications and skills meet the requirement.

c) Transportation/Traffic Arrangement

Traffic arrangement starts when heavy equipment is mobilized to the project locations. Once the dredging begins, trucks will be entering the dredging locations and trucks with dredged materials will go to the disposal site. In addition, parking arrangement for trucks and other project vehicles around project locations will be needed (while waiting for dredged materials).

d) Dredging

Dredging of floodways/drainage canals/waduk will most probably use mechanical equipment e.g. excavator on pontoon and barges (as shown in Figure II-7) with a small tugboat in the water and in the smaller canals a floating bulldozer.

Dredging methods that will be implemented in each location will be adapted based on the characteristic of each location. Details are shown on Table II-7.

II-18

e) Separating Bulk Refuse

Prior to transporting the dredged materials to the designated disposal area in West Ancol, it is necessary to undertake separation of bulk refuse materials such as large timber blocks. Separated bulk refuse will be transported to landfill facilities (i.e. Bantar Gebang) to avoid stench at dredging locations. Transporting bulk refuse to Bantar Gebang will be carried out in cooperation with private sectors as well as Dinas Kebersihan (Sanitation Agency) of DKI Jakarta and Sudin Kebersihan (Sanitation Sub-agencies) Central, West, and North Jakarta.

f) Transporting Dredged Materials

After loading the sediment directly into watertight dump trucks the sediment will be transported by dump truck to the disposal area. The distance between disposal area and dredging locations varies, generally up to 20 km. JEDI is responsible for transportation and dumping into the disposal area (see Figure II-8 for the illustration of dumping in land based disposal area) in the Ancol area, while the overall management of the disposal area will be under PT Pembangunan Jaya Ancol, Tbk.

Transportation of sediment will be carried out by watertight trucks to prevent mud spilling onto the roads. Furthermore, fixed trucks routes will be arranged to and from the five locations. Predicted routes for each dredging location are as follows:

• Cengkareng Drain; Jalan Daan Mogot Tol Jl. Laks. R.E. Martadinata Ancol

• Ciliwung River – Gn Sahari; Jalan Gunung Sahari Jl. Laks. R.E. Martadinata Ancol

• Sentiong River – Sunter; Jalan Utan Panjang Jl. Bunyamin Sueb Jl. Laks. R.E. Martadinata Ancol

• Lower Sunter Drain Jl. Perintis Kemerdekaan Jl. Yos Sudarso Jl. Laks. R.E. Martadinata Ancol

• Waduk Melati; Jl. Kebon Kacang Jl. KH. Mas Mansyur Jalan Cideng Jl. KH. Hasyim Ashari Jl. Juanda Jl. Gunung Sahari Jl. Laks. R.E. Martadinata Ancol.


II-19

Figure II-8 Dumping with Dump Truck in Land Based Disposal Area

g) Disposal Area

Based on previous studies, the most viable option for Confined Disposal Facilities is at the eastern of West Ancol Stage I with an area of ± 119 Ha. The Government of DKI Jakarta through Governor’s Letter No. 1776/-1.793.43 dated 25 August 2009 regarding Dumping Site of Dredged Materials from 13 Rivers/Retention Basins in DKI Jakarta established the reclamation area in the eastern side of West Ancol as the Dumping Site/Disposal Area to receive dredged materials from 13 rivers and 6 waduks in DKI Jakarta. The Regional Environmental Agency (BPLHD) of DKI Jakarta has approved the Updating of RKL and RPL on the Development of Eastern Side of West Ancol of ±119 Ha based on the letter No. 02/Andal/-1.774.151 dated 30 March 2009.

h) Land Cleaning and Rehabilitation

During the dredging period, the locations for loading the dump trucks will be cleaned daily to remove any sediment spilled during the loading. After the dredging and transportation of the sediment are completed, any damages will be repaired and temporary removed infrastructure (e.g. fences) will be replaced as part of land rehabilitation activities.


II-20

2.2.2.3 Post-operations

This stage covers the following activities:

a) Heavy Equipment Demobilization

Vehicles and equipment demobilization will be implemented in several phases from dredging location to disposal area, as set by the contractors.

b) Workers Demobilization

Before workers demobilizations starts, contractors need to notify all the workers. Demobilization can only be implemented after all parties fulfill each of their responsibilities.

c) Dredging Maintenance

The canals and waduk will be routinely maintained, considering the sedimentation rate in the canals, and especially the waduk, can be very fast. Therefore if the canals and waduk are not maintained routinely, the flow capacity of the canals and retention capacity of the waduk will become less than the design capacity which will mean an increased risk of flooding.

2.3 ALTERNATIVE ASSESSMENT

This section presents an alternative assessment in dredging activities in floodways/drainage canals/waduk to mitigate flood in Jakarta. The alternatives will be selected based on environmental, technology and economic aspects. All alternatives will be considered before selecting the most beneficial and effective in terms of management, design and reducing impacts.

• Alternative Dredging Locations

Selections of floodways/drainage canals/waduk location which will be dredged in Phase 1 DKI Jakarta with regards to flood mitigation are based on the relatively minimum environmental and social impacts.

• Alternative Dredging Method

Selection of dredging method will consider the condition of dredging location and its surroundings (site specific). On some locations with less plastic garbage in the sediment like near the estuary of the Cengkareng Drain, dredging works might be executed with a cutter suction dredging equipment.


II-21

• Alternative to Transport Dredged Materials

For transporting the dredged materials watertight dump trucks will be used in order to prevent soil/mud spilling on the roads or environment. Routes of the trucks will observe the road level and spots of traffics.

• No-project Alternative

If the dredging of floodways/drainage canals/waduk in DKI Jakarta to mitigate flooding is not implemented, flood risk will increase. The water capacity of the rivers in Jakarta will no longer be available to receive waters from upstream. This is also affected by sea level condition which can block the waterway to the sea. Meanwhile, if the dredging is implemented, the rivers capacity will increase to 50% from the existing capacity, therefore an expected alleviation of flood areas in DKI can be accomplished.

2.4 OTHER ACTIVITIES

In general, other activities around study areas that will be affected are informal business activities such as transportation to cross the river (’eretan’), worm collectors (for fishing bait or fish food), horticulture on riverbanks, scavengers, motorcycle taxi drivers, etc). These informal activities include businesses along the river channels. Out of these activities, there are also fishermen and fish processing industries around the floodplains.

Formal businesses affected include trading and traditional markets, offices, industries and warehouse are usually managed by employees who reside around or outside the project areas. To support formal activities, either for public or goods transportation, road access for transportation is necessary. Each area is also a trading area for other surrounding areas. The formal business activities can last for 24 hours a day.

Communities around the project locations are potentially impacted by project activities. Generally, daily activities include working, going to schools, trading, industrial, etc.

• Cengkareng Drain

Based on preliminary assessment, there are approximately 824 affected people residing in 535 buildings in Cengkareng Drain area. Based on the building usage, activities around the location includes trading (55%), housing (24%), public facilities (3%) and a combined use like shop houses, office houses (18%). Specific activities along the riverbanks that will be affected include Kemiri traditional market, informal business, i.e. fishing baits collectors, crossing-the-river boats, and horticultures farming.


II-22

• Ciliwung – Gunung Sahari

There are permanent and semi-permanent buildings along Ciliwung Gunung Sahari River which mostly are used for trading/business and offices. Therefore, community’s activities vary from businessmen to workers. Numbers of affected people in this area are relatively small and they are located around North and South Gunung Sahari, and West Pademangan.

• Sunter – Sentiong River

This is a relatively crowded location, where estimated numbers of affected-people are around 3,264 with around 816 units building which mostly are residences. Building use around project locations are for business/trading (1%), housing (69%), public facilities (3%) and combined use as shop houses and office-houses (27%). People activities around the project location include workers, technicians, and traders in local traditional markets, e.g. Sunter, Serdang and Sunter Mas. Other businesses in the area include bean curd (tofu) industry, building materials and florists.

• Lower Sunter

Based on its location, this river is split into three sections i.e. (a) Kelapa Gading residential gate at Jl. Perintis Kemerdekaan – Jl. Laksmana Yos Sudarso, (b) Cempaka Putih Intersection– Jl. Laksamana Yos Sudarso to Plumpang intersection, and (c) between Simpang Plumpang – Jalan Cilincing Raya. Many activities occur here especially in sections (b) and (c). Spaces between river block with inspection trails are mostly used for gardens, chicken farms, RT/RW Offices/Pos security or backyards. On several locations, there are also areas used as disposal sites.

• Waduk Melati

The location is surrounded by tall office buildings, hotels and trade centers. 78% of economic activities around the project are trading, while the rests are civic officials and workers. There are no social issues in this location.


III-1

CHAPTER III ENVIRONMENTAL BASELINE

Locations of Phase 1 of the JEDI Project are in 3 (three) administrative cities i.e. Central Jakarta (Sentiong-Sunter, Ciliwung-Gn. Sahari, and Waduk Melati), North Jakarta (Ciliwung-Gn. Sahari, and Lower Sunter), and West Jakarta (Cengkareng Drain). Environmental baseline conditions in these locations are described in this chapter.

3.1 SPATIAL PLANNING COMPONENTS

Geographically, Indonesia’s Capital Jakarta is crossed by many rivers such as Mokervart, Angke, Pasanggrahan, Ciliwung, Cideng, Krukut, Grogol, Sekretaris, Cipinang, Sunter, Buaran, Cakung as well as swamps such as Badak, Buaya, Jati, and Mangun. The low land areas with elevation of -1.0 to + 3.0 occupy much of Central and North Jakarta, are natural retention basins.

Watersheds of the above rivers form a river area in the shape of a mountain with Ciliwung Watershed at its peak (Figure III-1) (an area of approximately 150 km2). The geomorphology indicates that in natural conditions the large upland areas of Jakarta should not be flooded, as runoff from the upper basin spreads into large wetlands in the lower basin. This fact allowed the area to be the center of activities of Jayakarta Kingdom, later known as Batavia (during the Dutch colonial era), and currently known as Jakarta.

In its present form, Jakarta no longer has sufficient number of deltaic wetlands and freshwater swamps. The remaining swamps have been converted into mixed-use residential and business centers, such as Pantai Indah Kapuk and Kelapa Gading. Jakarta also has no riverbanks as the main river channel has been narrowed due to its residents’ activities. The bottom line is that Jakarta does not have a proper drainage system.

At the center of the basin where rivers enclosed Jakarta is the City of Depok, Regency/City of Bogor, which also has a large population, and extensive residential areas such as Cibubur, Sawangan, and Bekasi. Rapid and widespread residential developments in the mid-basin river area caused the disappearance of lakes, flood plains, and open/protected lands (water infiltration areas).

Large areas in the upper Ciliwung River Basin include Bogor, Puncak and Cianjur districts (BOPUNJUR) have been converted to villas and other housing purposes (1000 new villas since 2000). This resulted in a further reduction of river catchment areas as flood control system in DKI.


III-2

From the above descriptions, it can be concluded that geographically Jakarta is a strategic area, close to the sea, and can serve as center of activities (residential, government and business) with easy access. However, due to uncontrolled land use planning Jakarta has no flood control capacity.

Jakarta experience major floods in 1621, 1654, and 1918, and further in 1976, 1996, 2002, and 2007. Flooding in 1996 covered almost all parts of Jakarta and became a national tragedy that attracted international attention. Major floods are expected to occur every 5 years. In early 2002 and 2007, Jakarta experienced major flooding covering more and more area.

• Basically, Jakarta has become a flood-sensitive area due to:

• Influx of water that exceeds the discharge capacity of the rivers.

• Insufficient drainage capacity and lack of water catchment areas in Jakarta.

• Difficulties in rivers maintenance as most riverbanks have been converted to residential areas.

• Poor waste management system and lack of public awareness in environmental hygiene.

• Environmental deterioration in catchment areas due to uncontrolled land use.

Cengkareng System

At the western area of DKI Jakarta, Grogol, Angke and Pesanggarahan floodways join together and flow to Cengkareng Drain which ends in Java Sea. In addition to the above mentioned floodways, Kali Mookervart, a tributary of Cisadane River also flows to Cengkareng Drain.

West Canal Floodways System

Almost all water from Ciliwung River is directed to West Canal Floodway trough Manggarai floodgate. Rivers from Krukut Dam and upstream area of Kali Angke is also directed to the West Canal.

The responsibility for Ciliwung River at the upstream area of Manggarai Dam including the West Canal Floodway is fall under Central Government (PIPWS-CC), while the downstream area of Ciliwung River from Manggarai Dam to the North is a drainage system directing local flood water to Java Sea. This section is fall under the responsibility of DKI Jakarta Government.


III-9

Sunter System

Kali Cipinang connects with Kali Sunter in the lower area and flow to Java Sea trough Tanjung Priok Port. To maintain the water level during rainy and dry seasons, water level at this system is monitored and managed through various water gates.

Cakung System

The Jati Kramat and Buaran Rivers merged to form Kali Buaran which also merges with Cakung Drain, which is a man-made river to channel down Cakung Lama River. Cakung Drain also flows to Java Sea.

Currently East Canal Floodway is under construction. In the future, the Floodway will accommodate water flow from upstream area of East Jakarta such as Kali Cipinang, Kali Sunter, Kali BUaran, Kali Jati Kramat and Kali Cakung, and discharge it to the Java Sea.

3.2.2.2 Odor

Odor measurement results of NH3 (ammonia), H2S (Hydrogen sulphide), CH3SH (Methyl mercaptan) and (CH3)2S (Methyl sulphide) were compared to the standards prescribed in Minister of Environment Decree No. 50 of 1996 concerning Odor Level Standards. The results indicated that odor quality in the five study areas were within the standards. Measured methyl mercaptan concentrations were from 0.00095 to 0.00182 ppm whilst methyl sulphides were from 0.00098 to 0.00505 ppm. Details of odor measurement result are showed in Table III-11.

3.2.4 Topography

Topography of DKI Jakarta area is categorized as both flat and sloping areas. Altitudes from the coastal area to the flood canal range from 0 to 10 m above sea level (asl) measured from the zero point in Tanjung Priok. While from the flood canal to the southern border of DKI Jakarta, the altitudes range from 5 to 50 meter asl.

The coastal area is a marsh area or permanently flooded area during the rainy season. To the south of the flood canal is lowland area with altitudes between 50 to 75 m.

There are six rivers flowing through DKI Jakarta area, namely Ciliwung, Grogol, Krukut, Angke, Pesanggrahan and Sunter.

3.2.5 Geological Formation and Soil

DKI Jakarta region consists of alluvial deposits from Pleistocene Era with ± 50m thickness. The southern region consists of alluvial layer extending from east to west at approximately 10 km distance from the coastal area. Underneath this layer lie older sediments layers. Soil stability in DKI Jakarta region follows the same pattern as the depth of the bed rock in the northern region (10 - 25 m depth). Further south, the bed rock becomes shallower (8 - 15 m).

3.2.6 Surface Water Quality

Water quality assessment is classified into physical, chemical and microbiological characteristics. The results of water quality measurements are compared with DKI Jakarta Governor Decree No. 582 of 1995 concerning Usage and Water Quality Standards for River/ Water Body and Wastewater in DKI Jakarta.

Surface water quality sampling campaign was conducted at each dredging site i.e. Waduk Melati (WMA 1 and WMA 2), Cengkareng Drain (SCA 1, SCA 2 and SCA 3), Ciliwung–Gn. Sahari River (GSA 1 , 2 GSA, and GSA 3), Lower Sunter (KSA 1, KSA 2, and KSA 3) and Sentiong-Sunter (SSA 1, 2 SSA, and SSA 3). The results are shown in Table III-13 to Table III-17.

III-23

As shown in Table III-13 to Table III-17 measurements of a number of parameters i.e. COD, BOD, oil and grease, detergent and organic substances at certain sampling locations exceeded the standards prescribed by DKI Jakarta Governor Decree No. 582 of 1995.

Measurements of pH in all sampling locations showed values within the standards. This indicated normal acidity levels.

COD standard set by the 1995 Decree is 30 mg/L. The laboratory results showed that the value in almost all sampling locations exceeded the standard, except at the SCA 1 and SCA 2 (Cengkareng Drain). BOD values were still within the specified standards of 20 mg/L in almost all sampling locations except at Waduk Melati and SSA-3 (Sentiong-Sunter River). The analytical results of organic matter contents indicated that the permanganates value was higher than the standard of 25 mg/L in almost all sampling locations. The high organic content may be caused by the accumulation of domestic waste or other activities around the sampling location.

Microbiological analysis showed compliance with the standards by the 1995 Decree.

TSS (Total Suspended Solid) is one of the water quality indicators associated with the physical appearance and turbidity. TSS can be defined as the suspended solids in water in forms of organic and inorganic materials that can be filtered with a filter of 0.45 μm. The suspended material has adverse effects on water quality because it reduces the penetration of sunlight into the water body, increases water turbidity that limits organisms’ growth. Turbidity is closely related to the concentrations of suspended materials in the water. Suspended materials in the water are typically composed of silt, clay and mud as natural inorganic materials or in the form of organic material floating in the water as natural sources and waste resulted from human activities such as industrial activities, agriculture, or household activities. TSS analysis results in all sampling sites showed compliance with the specified standards.

3.2.7 Sediment Quality

Sediment quality data presented here is based on Preliminary studies of Sediment Quality Assessment Study undertaken by the World Bank on 18 rivers / channels and reservoirs in Jakarta in 2008.

Laboratory analyses include physico-chemical characteristics such as particle distribution, total metal, hydrocarbon contents and TCLP.

There is currently no national standards for sediment quality and therefore the results were compared to the United States Environmental Protection Agency standards (USEPA R9 PRG) for soil quality in residential and


III-24

industrial areas, Dutch Environmental Quality Guidelines for soil quality in residential area, South Korean Government standards for soil in industrial area, and Australian and New Zealand’s National Ocean Disposal Guidelines for Dredged Material.

Sediment characteristics, based on particle distribution criteria, showed that the majority of sediments were silty clay with sand (Table III-18).

Metal contents in the sediment were generally below the standards (Table III-19).

TCLP results revealed that all parameters were below the standards prescribed in the Government Regulation No. 18 of 1999. This indicated that sediments from the five study areas would not cause environmental pollution in the events of leaching (Table III-20 and Table III-21).

In addition to the study conducted in 2008, the Jakarta Flood Management-Pilot Dredging Project assisted by the Dutch Government conducted similar analysis of eight (8) composite sediment samples collected from nine sampling points (six in the Kali Mati and three in the Pademangan Channel).

Based on the laboratory result, the sediment does not have characteristic of explosive, flammable, reactive, reaction with water, potential H2S, CN-, NH3, physical and color forming and corrosive.

TCLP result of the samples is below the laboratory detection limit. Zinc is the only parameter which was detected during the test. Zinc concentration in the leaching is below regulation limit. The highest detected zinc concentration is 4.92 mg/l. In general, concentration of zinc in the Kali Mati is higher compared to concentration of zinc in the Pademangan Channel. The present of zinc indicates that the Kali Mati and Pademangan Channel have been contaminated by domestic wastes.

The toxicity level of the samples based on value of LD50 (122,000 mg/kg – 139,000 mg/kg of body weight) is categorized as relatively harmless according to Government Regulation No. 74 of 2001.

Based on the above mentioned analysis (characteristic test, TCLP and LD50), sediment from the Kali Mati and Pademangan Channel are not categorized as hazardous waste according to the Indonesian regulation. Acute toxicity level of the sediment for human health is identified as relatively harmless. High concentration of total coliform and organic matter in the water gives indication of domestic wastes pollution in the Kali Mati and Pademangan Channel.

3.3 BIOLOGICAL COMPONENTS

Crops are generally found in the study areas as well as canopy plants along the streets and city parks, and decorative plants in residential houses.

Typical species of canopy plants are angsana (Pterocarpus indicus), mahogany (Swietania macrophylla), acacia (Acacia auriculiformis), johar (Cassia siamea), bamboo (Bambusa sp), red dadap (Erythrina sp), bintaro (Carbera odallam), coconut (Cocos nucifera), banyan (Ficus benyamina), capes (Mimosops elengi), long strip umbrella (Filicium decipens), glodogan pole (Polyalthia longifolia), and ketapang (Terminalia catappa).

3.4.2.2 Education

Education in DKI Jakarta is available from kindergarten to university level. The quality of education is highly variable from the luxurious air conditioned building to near-collapse building, generally found in primary and junior secondary schools.

In the past few years, schools with curriculum from other countries such as Singapore and Australia have also come to existence. Another option is schools with Indonesian curriculum but with different teaching methods to a more traditional teaching method that is generally applied.

Availability of facilities and resources in education indicates the level of human resources development. Education is essential to improve intellectual level, and to develop capability and personality. The availability of facilities and numbers of teachers in the project area is considered as adequate (see Table III-24).

Almost each sub-district has educational facilities either privately or government owned, especially from primary school level to senior high school level. Therefore, residents of Jakarta should at least be able to have senior high school education. Furthermore, DKI Jakarta Government applies no school fee policy for its residents to participate in compulsory education.

f. Dredging and refuse clearing should be carried out on a regular basis to reduce frequency of flooding in their areas.

3.4.4.6 Transportation

Baseline information on current traffic conditions at project locations are provided below:

• Cengkareng Drain

The traffic around the project location (Daan Mogot Street) was considered as heavy traffic due to mass rapid transit (busway) line. Existing research report revealed the V/C ratios during morning and evening rush hours were between 0.82 – 0.90. Daan Mogot Street consisted of 2 major lanes divided by a road separator whereby each major lane had 3 lanes and one lane was used as Transjakarta Bus lane. The road conditions were generally in good shape. Heavy Goods Vehicles (HGVs) used Daan Mogot Street to deliver goods outside Jakarta from factories across the street.

• Ciliwung-Gn. Sahari Drain

The traffic around the project location (Gn. Sahari Street) was considered as heavy traffic due to mass rapid transit (busway) line. Existing research report revealed the V/C ratios during morning and evening rush hours were between 0.78 – 0.88. Similar to Daan Mogot Street, Gn. Sahari Street also consisted of 2 major lanes divided by a road separator whereby each major lane had 3 lanes and one lane was used as Transjakarta Bus.

Kartini Road is situated to the west of Ciliwung-Gn. Sahari Drain. The road is 6 m wide with 2 lanes. It is a popular area for tropical fish kiosks (89 kiosks) which potentially cause high number of vehicles.

• Sentiong-Sunter Drain

The traffic around the project location (Suprapto – Kemayoran – Sunter route) was considered as heavy traffic due to mass rapid transit (busway) lines across parts of the project location. Existing research report revealed the V/C ratios during morning and evening rush hours were between 0.70– 0.85.


III-42

• Lower Sunter Canal

The traffic around the project location (Kelapa Gading Street – Priok route) was considered as heavy traffic due to mass rapid transit (busway) lines across parts of the project location. Existing research report revealed the V/C ratios during morning and evening rush hours were between 0.72 – 0.94. Parts of the canal include Pasar Ular, Tanjung Priok which is a major shopping area with narrow road. Therefore, high level of vehicles could potentially create even heavier traffic during dredging equipment operation.

• Waduk Melati

The traffic around the project location (Kebun Kacang Street –Cideng – Pasar Baru route) was considered as heavy traffic due to mass rapid transit (busway) line. Existing research report revealed the V/C ratios during morning and evening rush hours were between 0.74 – 0.90. Waduk Melati is surrounded by shopping centers and apartments at certain locations there are areas to place dredging materials and to park dredging equipment.

Details v/c calculations around the study areas are provided in Table III-31.

CHAPTER IV SCOPE OF STUDY

4.1 SIGNIFICANT IMPACT ASSESSMENT

4.1.1 Scoping Process

Scoping is necessary to ensure that all potential and hypothetical impacts are identified so that they can be reviewed within the AMDAL process. The scoping process is to identify the potential impacts from the proposed activities, to assess and prioritize the hypothetical impacts (MoE Decree No. 08/2006). The process is illustrated in Figure IV-1 below.

Figure IV-1 Scoping Process

Scoping is conducted to focus the different aspects of the proposed activity and environmental components on the significant impacts. The scoping is conducted in three stages i.e.:


IV-2

1. Identification of potential impacts.

2. Evaluation of potential impacts to establish hypothetical significant impacts.

3. Prioritization of the hypothetical significant impacts.

Identification of Potential Impacts

Identification of potential impacts was conducted using a simple matrix method. The identification process included collection of all potential impacts, regardless of magnitude and importance. The potential impacts were identified based on experts’ opinions and inputs received from public consultation events (see Section 4.1.1.2). At this point, there was no assessment to determine whether the impact was significant. Potential impacts that may occur are as follows (see Table IV-1):

1. Transportation/Traffic. In the operations phase, the impacts on traffic are related to street closure due to mobilization of heavy equipment and transport of dredged materials. Furthermore, equipment mobilization can cause disruption to road surface due to spillage and negligence.

2. Air quality. Impacts on air quality during the operations phase due to equipment mobilization and operations of machineries and heavy equipment, and the land transport using trucks from dredging locations to Ancol.

3. Noise. Disruptions to noise levels during the operations phase due to equipment mobilization and operations of machineries and heavy equipment, and the land transport using trucks from dredging locations to Ancol.

4. Odor. Odor impacts due to the dredging of sediment.

5. Water discharge rate. Impacts on water discharge rate in the operations phase due to dredging activities that will increase the capacities of floodways/drainage canals and waduks, which consequently increase discharge rate and reduce the risk of flooding. In the post-operations phase, maintenance dredging will maintain the holding capacities of floodways/drainage canals and waduk in order to continue reducing flood risk.

6. Surface water quality. Impacts on water quality in the operations phase due to dredging activities that will increase Total Suspended Solids content and consequently may disturb water biota.

7. Sea water quality. Changes to sea water quality are considered as a derivative impact of the change of water quality upstream during dredging activities.

8. Solid waste. Potential impacts on solid waste in the operations phase are due to dredging and transport of dredged materials which may cause sediment and solid waste spills around the project locations. This could


IV-3

consequently impact public health and lead to negative public perceptions of the dredging activities.

9. Terrestrial biota. Impacts on terrestrial vegetation may occur during workers and heavy equipment mobilization prior to the commencement of the dredging activities. Once the dredging is completed and the areas will be rehabilitated.

10. Aquatic biota. Disturbance to aquatic biota is a derivative impact from the changes to surface water quality.

11. Employment and business opportunities. Impacts on employment and business opportunities are due to workers mobilization in the operations phase. The employment opportunities are limited to 31-41 workers at each location.

12. Urban infrastructure and facilities. In the operations phase, impacts on the city’s infrastructure and facilities may due to mobilization of heavy equipment and transport of dredged materials.

13. Community order and security. Impacts on community order and security may potentially occur during the pre-operations phase (public consultation) and the operations phase (during workers mobilization, heavy equipment mobilization, dredging and transport of dredged materials). The impacts are the derivative impacts of impacts on other environmental components.

14. Community perception. Impacts on community perception can potentially occur in the pre-operations phase (public consultation) and the operations phase (during workers mobilization, heavy equipment mobilization, dredging and transport of dredged materials). All activities during the operations phase may generate the environmental impacts on air quality, noise level, odor, surface water quality and solid waste. The environmental impacts can potentially impact community perception on the dredging activities. Dredging maintenance can have positive impacts toward community perception.

15. Public health. Public health impacts during the operations phase are due to dredging activities and transport of dredged materials to the disposal area.

16. Environmental aesthetics. Similar to the impacts on community such impacts can potentially occur during the operations phase i.e. dredging and transport of dredged materials to the disposal area. Land cleaning and rehabilitation will be a positive impact on environmental aesthetics.

17. Environmental sanitation. Similar to the impacts on public health, impacts on environmental sanitation will occur during the operations phase (dredging and transport of dredged materials). Land cleaning and rehabilitation will be a positive impact on environmental sanitation.

4.1.1.2 Public Consultation

Community involvement and information transparency is crucial for the continuation of the dredging of floodways/drainage canals and waduks in DKI. Continuous dialogue with the affected communities is expected to occur directly and indirectly while the project is implemented. Referring to Head of Environmental Impact Management Agency (Bapedal) Decree No. 08/2000 on Community Involvement and Information Disclosure in the EIA process, the Project Management Unit (PMU), Directorate General of Water Resources and Ministry of Public Works as the project proponent issued an announcement about the Phase 1 dredging activities in Warta Kota Newspaper on 19 July 2009. A copy of the announcement is provided in Appendix 1. Following the announcement a public consultation event was held on 19 August to disseminate information about the project to the public. On 16 September 2009, the project proponent carried out another consultation event concerning the Terms of Reference of the Phase 1 dredging activities. As the AMDAL study progressed, another consultation event was held on 29 December 2009 in order to discuss in more details the impacts of the proposed activities on physico-chemical, biological, socio-economic, cultural and public health components, as well as the proposed management measures and monitoring. Minutes of meetings, lists of attendance and presentations delivered at the consultation events are available in Appendix 1.

The public consultation events were to fulfill the requirements on involving the community and disseminate environmental information as stipulated by the Head of Environmental Impact Management Agency (Bapedal) Decree No. 08/2000 on Community Involvement and Information Disclosure in the EIA process. The events were attended by the affected communities (represented by sub-district representatives, village chiefs and representatives of the district council), the AMDAL Evaluation Commission, relevant government agencies, and regional Ministry of Environment offices of West Jakarta, North Jakarta, and Central Jakarta. The events were held at the DKI Jakarta Environmental Impact Management Agency office.

4.1.1.3 Evaluation of Potential Impacts

The evaluation of potential impacts aims to eliminate potential impacts that are considered irrelevant/unimportant, in order to identify hypothetical significant impacts that require more in-depth examinations. The results of the hypothetical significant impact are shown in Table IV-2.

The methods used to evaluate the hypothetical significant impacts included discussions between the AMDAL study team members and the project proponent, literature studies, field observations, and discussions and comments received during the public consultation events. Relationships


IV-6

between the various environmental, social and other components determine whether the impacts are primary, secondary, or tertiary.

The criteria for identifying hypothetical significant impacts are based on Head of Bapedal Decree No. Kep-056/1994 regarding Guidelines on Significant Impact Determination, and considering the inputs from received from consultations with the public and AMDAL Evaluation Committee. Evaluation outcomes on the potential impacts the dredging activities are as follows:

1. Transportation/Traffic. In the operations phase, the impacts on traffic are related to street closure due to mobilization of heavy equipment and transport of dredged materials. Furthermore, equipment mobilization can cause disruption to road surface due to spillage and negligence.

2. Noise. Disruptions to noise levels during the operations phase due to equipment mobilization and operations of machineries and heavy equipment, and the land transport using trucks from dredging locations to Ancol.

3. Odor. Odor impacts due to the dredging of sediment.

4. Water discharge rate. Impacts on water discharge rate in the operations phase due to dredging activities that will increase the capacities of floodways/drainage canals and waduks, which consequently increase discharge rate and reduce the risk of flooding. In the post-operations phase, maintenance dredging will maintain the holding capacities of floodways/drainage canals and waduk in order to continue reducing flood risk.

5. Surface water quality. Impacts on water quality in the operations phase due to dredging activities that will increase Total Suspended Solids content and consequently may disturb water biota.

6. Employment and business opportunities. Impacts on employment and business opportunities are due to workers mobilization in the operations phase. The employment opportunities are limited to 31-41 workers at each location.

7. Urban infrastructure and facilities. In the operations phase, impacts on the city’s infrastructure and facilities may due to mobilization of heavy equipment and transport of dredged materials.

8. Community order and security. Impacts on community order and security may potentially occur during the pre-operations phase (public consultation) and the operations phase (during workers mobilization, heavy equipment mobilization, dredging and transport of dredged materials). The impacts are the derivative impacts of impacts on other environmental components.

9. Community perception. Impacts on community perception can potentially occur in the pre-operations phase (public consultation) and the


IV-7

operations phase (during workers mobilization, heavy equipment mobilization, dredging and transport of dredged materials). All activities during the operations phase may generate the environmental impacts on air quality, noise level, odor, surface water quality and solid waste. The environmental impacts can potentially impact community perception on the dredging activities. Dredging maintenance can have positive impacts toward community perception.

Figure IV-2 illustrates the scoping process implemented in this study from the determination of potential impacts to prioritization of hypothetical significant impacts.

4.1.1.4 Hypothetically Significant Impact Priorities

The objective of the scoping of significant impacts is to categorize the significant impacts which were identified in the previous phase to ensure their classification and impact prioritization. The method used is the analysis of the relationships between activity components and the environmental components, where each component affects and depends on one another. In this section, hypothetical significant impacts as identified previously are categorized and ranked by priority for detailed assessment later in the ANDAL. Table IV-3 lists the hypothetical significant impacts and ranks them from the highest to the lowest priority. Figure IV-2 illustrates the scoping process implemented in this study from the determination of potential impacts to prioritization of hypothetical significant impacts.

CHAPTER V SIGNIFICANT IMPACT PREDICTIONS

5.1 IMPACT IDENTIFICATION

Based on the project description of the dredging of floodways/drainage canals and waduks in Phase I of the JEDI Project, as outlined in Chapter II, the activity components of pre-operations, operations and post-operations phases with potential to cause impacts on physico-chemical, biological, socio-economic, socio-cultural and public health components were identified. The identification used an impact identification matrix (checklist) as illustrated in Table V-1 with (-) for negative and (+) for positive impacts, and (IS) for insignificant and (S) for significant impacts.

5.2 PREDICTION OF SIGNIFICANT IMPACTS

5.2.1 Pre-Operations Phase

5.2.1.1 Technical Design

The technical design activity for the dredging of floodways/drainage canals and waduks in the Phase 1 of the JEDI Project will not affect any environmental components.

5.2.1.2 Consultation

Public consultation regarding the dredging of floodways/drainage canals and waduks in the Phase 1 of the JEDI Project is predicted to have both positive and negative impacts on community perception. Positive perceptions will arise from the expectations of the affected community that the dredging activities will minimize the risk of flooding in their areas. On the other hand, negative perception will arise from concerns due to the project impacts such as traffic, urban infrastructure disruption, disruptions to community activities, environmental contamination, excessive waste, noise and other impacts.

The impact on community perceptions during the pre-operations phase will be of high intensity but only affect limited numbers of people, and a short-term and reversible impacts; therefore this impact is categorized as either positive and negative significant (+/-S).


V-2

5.2.2 Operations Phase

5.2.2.1 Workforce Mobilization

A. Impacts on Socio-economic, Socio-cultural, and Public Health Components

1. Employment and Business Opportunities

Workforce recruitment in the operations phase will have positive impact in terms of employment and business opportunities. Dredging activities are predicted to have as many as 31-41 workers for each location and whenever possible workforce will be recruited locally, and therefore reduce the number of unemployment. Furthermore, the employment will bring positive impacts in terms of business opportunities for local communities, e.g. canteen/food stalls, etc.

Although this will be an ongoing process during the operations phase, only a small number of people will be employed by the project compared to the number of people who live in the area. Furthermore, the impact is of low intensity, cumulative, and only affecting a small number of other environmental components. Therefore this impact can be categorized as positive significant (+S).

5.2.2.2 Heavy Equipment Mobilization

a) Impacts on Transportation/Traffic

The mobilization of heavy equipment required for dredging will affect the traffic flow in each road in the project locations and the surrounding areas as the traffic volume will increase. Affected areas include Ciliwung River – Gn. Sahari due to numerous ornamental fish businesses (on Jl. Kartini) and the nearby Pasar Ular (Snake Market), and Sentiong Sunter where the Port of Tanjung Priok is close to the area.

The impact will be of low intensity, limited distribution at each location. However it will be accumulative and other environmental components may be impacted. The impacts will be temporary during the transport of heavy equipment and will be reversible. Therefore, the impact is considered as negative significant (-S).


V-3

b) Impacts on Socio-economic, Socio-cultural, and Public Health Components

1. Urban Infrastructure and Facilities

Mobilization of heavy equipment can potentially has impact on existing urban infrastructure and facilities at each project location, which can cause disruption and damage to those facilities.

Although the impact is limited to areas within each project location and reversible, it will be of high intensity, affect relatively large number of people and other environmental components. Therefore, the impact is considered as negative significant (-S).

2. Community Order and Security

Mobilization of heavy equipment can also potentially impact community order and security around the project locations i.e. the community and the project itself. The community may be affected in the case of disruptive movements of the equipment due to dust and noise whilst the project can be affected if there is theft and vandalism in the project locations.

Such impact is of low intensity, only limited to project locations but will affect a large number of people and may impact other environmental components during the heavy equipment mobilization. Therefore, the impact is considered as negative significant (-S).

3. Community Perception

Mobilization of heavy equipment during the dredging period will impact community perception around the project locations. The impact on public perceptions may occur due to noise and traffic disruption during the mobilization process.

This will be a low intensity impact, with limited distribution to the vicinity of each dredging location. The number of affected people is relatively large, reversible during the mobilization process and therefore this impact can be categorized as negative significant (-S).

5.2.2.3 Dredging

a) Impacts on Physico-Chemical Components

1) Noise

The dredging activities will have an impact on noise level around the project locations. The dredging activities are expected to be carried out during the night, so not to worsen the traffic congestion but this can potentially cause


V-4

opposite impacts on the noise level. The impacts have to be managed carefully due to the proximity of a number o f Phase 1 dredging locations to residential areas. Based on the noise measurements at project locations, the noise level during day time exceeded the prescribed standard for residential area. Hence, an increase of noise level at the vicinity of project locations is expected during dredging.

Impacts will occur at low intensity and will have a distribution limited to the vicinity of the project sites. There will be a large number of people and other environmental components that will be affected. The impacts will be during the project duration but reversible. This impact is categorized as negative significant (-S).

2) Air Quality and Odor

Dredging and separating bulk refuse materials in JEDI Phase 1 are predicted to reduce air quality and to increase odor level. Without proper management, the dredging materials may make the environment surrounding the project locations unhygienic and stench. As the dredging locations are mostly in densely populated areas (residential, trading, etc), the impacts on air quality and odor require particular attention.

The impact is of high intensity, affecting a large number of people and other environmental components. There will only be limited impacts that are cumulative in nature and of short duration during the dredging and separating of bulk material. Therefore, the impact is classified as negative significant (-S).

3) Water Discharge Rate

Dredging will impact water discharge rate of the dredged floodways/drainage canals and waduks. The anticipated dredging volume of ± 2,080,000 m3 will cause a minimum of 50% increase in each of the water bodies’ capacity, which will consequently increase water flows by ± 50%. Therefore, the risk of flooding will be reduced.

This will be a high-intensity and long-term impact until the post-operations phase, and the impacts will not be limited to each project area. Large numbers of people and other environmental components will be impacted. Therefore this impact can be categorized as positive significant (+S).

4) Surface Water Quality

Due to the nature of dredging activities, the surface water quality at each location will be impacted in the form of Total Suspended Solid increase. Baseline TSS concentrations indicated achievements of prescribed standard and the dredging activities may increase the TSS concentrations.


V-5

This impact will occur at low intensity with a distribution limited to each project location and reversible. It will affect a large number of people and other environmental components. If not managed properly, other environmental components will be affected and may last longer than the dredging period itself. This impact can be categorized as negative significant (-S).

5) Solid Waste

Dredging and separating bulk refuse materials in JEDI Phase 1 are predicted to increase solid waste. Without proper management, the dredging materials may make the environment surrounding the project locations unhygienic and stench. As the dredging locations are mostly in densely populated areas (residential, trading, etc), the impacts on solid waste require particular attention.

The impact is of high intensity, affecting a large number of people and other environmental components. There will only be limited impacts that are cumulative in nature and of short duration during the dredging and separating of bulk material. Therefore, the impact is classified as negative significant (-S).


1) Urban Infrastructure and Facilities

Operations phase of JEDI Phase 1 is predicted to impact urban infrastructure and facilities such as water pipe passing through floodways/drainage canals where dredging will occur. Without careful management, dredging activities can cause disruption and damage to those facilities.

Although the impact is limited to areas within each project location and reversible, it will be of high intensity, affect relatively large number of people and other environmental components. Therefore, the impact is considered as negative significant (-S).

2) Community Order and Security

Dredging activities with a total volume of ± 2,080,000 m3 will impact community order and security around the project location. The activity can potentially cause environmental disturbance to public activities due to noise from heavy equipment, sediment spills, increased in traffic volume, and in community order and security issues. As the dredging locations are mostly in densely populated areas (residential, trading, etc), the impacts on community order and security require particular attention.


V-6

Such impact is predicted to be of high intensity, only limited to project locations but will affect a large number of people and may impact other environmental components during the heavy equipment mobilization. Therefore, the impact is considered as negative significant (-S).

3) Community Perception

Dredging activities will have impact on community perception towards the activities, which potentially caused by environmental disturbance around the dredging locations, increased of noise levels due to the use of heavy equipment, and sediment spills. As the dredging locations are mostly in densely populated areas (residential, trading, etc), the impacts on community perception require particular attention.

The impact on community perception is predicted to be of high intensity, only limited to project locations but will affect a large number of people and may impact other environmental components during the heavy equipment mobilization. Therefore, the impact is considered as negative significant (-S).

5.2.2.4 Transporting Dredged Materials


The transportation of dredged materials from floodways/drainage canals and waduks in Phase 1 of the JEDI Project will impact the traffic flow on each road leading to the disposal area in Ancol.

Taking into account heavy traffic conditions around each dredging location (V/C ratios at Daan Mogot = 0.82-0.90, at Gunung Sahari = 0.788-0.88, Suprapto = 0.70-0.85, Perintis Kemerdekaan = 0.72-0.94, and Kebon Kacang = 0.74-0.90, assessments on increased of number of trucks from each dredging location to the designated disposal area are as follow:

- Cengkareng Drain:

Dredged materials = 1,300,000 m3 Truck capacity = 20 m3

Duration = 360 days Number of rotation per day = 104 trucks Dredging period = 12 hours Number of rotation per hour = 8 trucks

- Ciliwung-Gn. Sahari

Dredged materials = 160,000 m3 Truck capacity = 20 m3



V-7

- Sentiong-Sunter



- Lower Sunter



- Waduk Melati



It can be concluded from the above assessments that dredging activities in the Phase 1 of the JEDI project will increase vehicle rotation per hour, for 360 days, by 2-8 trucks per hour.

Such impact is predicted to be of high intensity, wide coverage area from the dredging location to the designated disposal area, cumulative in nature, reversible, and will impact other environmental components. Therefore, the impact is considered as negative significant (-S).



The transporting dredged materials activity along the roads from the project site to the disposal area will have impact on community perception towards the activities due to the potential environmental disturbance such as sediment spills and increased of noise levels due to heavy equipment mobilization, as well as more traffic congestion. As the dredging locations are mostly in densely populated areas (residential, trading, etc), the impacts on community perception require particular attention.

Such impact is predicted to be of high intensity, not only limited to project locations (as identified in Map IV-1 to Map IV-5) and will affect a large


V-8

number of people and may impact other environmental components during the transporting of dredged materials. Therefore, the impact is considered as negative significant (-S).

5.2.3 Post-Operations Phase

5.2.3.1 Heavy Equipment Demobilization


The demobilization of heavy equipment required for dredging will affect the traffic flow in each road in the project locations and the surrounding areas as the traffic volume will increase. Affected areas include Ciliwung River – Gn. Sahari due to numerous ornamental fish businesses (on Jl. Kartini) and the nearby Pasar Ular (Snake Market), and Sentiong Sunter where the Port of Tanjung Priok is close to the area. The same impact prediction applies to activity component transportation and traffic arrangement.

This will be an impact of low intensity, with limited distribution to each location, however it will be accumulative and other environmental components may be impacted. The impacts will be temporary during the transport of heavy equipment and will be reversible. Therefore, the impact is considered as negative significant (-S).

5.2.3.2 Maintenance Dredging

a) Impacts on Physico-Chemical Components


Maintenance dredging of floodways/drainage canals and waduks in the Phase 1 of JEDI Project will affect the water discharge rate. With maintenance, dredging capacity of floodways/drainage canals and waduks will be maintained and the risk of flooding will be minimized further throughout a period of time.

This will be a high-intensity and long-term impact, and the impacts will not be limited to each project area. Large numbers of people and other environmental components will be impacted. Therefore this impact can be categorized as positive significant (+S).



The dredging activity will have impact on community perception towards the activities due to the potential environmental disturbance such as sediment


V-9

spills and increased of noise levels due to heavy equipment mobilization, as well as more traffic congestion. As the dredging locations are mostly in densely populated areas (residential, trading, etc), the impacts on community perception require particular attention.

Such impact is predicted to be of medium intensity, not only limited to project locations, reversible and will affect a large number of people and may impact other environmental components during the dredging maintenance. Therefore, the impact is considered as either positive or negative significant (-/+S).

CHAPTER VI SIGNIFICANT IMPACT EVALUATION

6.1 SIGNIFICANT IMPACT ASSESSMENT

6.1.1 Pre-Operations Phase

6.1.1.1 Impacts on Socio-economic, Socio-cultural and Public Health Components


Public consultation designed to inform the affected community about the dredging activities is expected to have positive and negative impacts on community perceptions. Positive perceptions will arise from the community expectations that the dredging activities will reduce the risk of flooding in their areas. Negative perceptions will be due to concerns about potential negative impacts from dredging perceived by the community such as traffic, disruption to urban infrastructure and daily activities, odor, and noise.

Environmental management procedures:

• Consultation with the community at the dredging locations concerning the purposes and benefits of the project before commencement of dredging activities.

• Coordination with community leaders before the commencement of dredging activities.

6.1.2 Operations Phase

6.1.2.1 Impacts on Physico-Chemical Components

1) Noise

Dredging activity and transporting of dredged materials during the operations phase will significantly impact air quality and odor concentrations. Increased in noise level may further create negative perception in the community who live close to the dredging locations.

Considering the proximity of dredging activity to residential area, the high intensity of the impact i.e. limited within ± radius 100 m, and the plan to dredge during the night time period, the impacts on noise and odor require particular attention.

Environmental management procedure:

• Carry out the dredging in an efficient manner to minimize the impacts on noise and odor.


VI-12

• Follow standard operating procedures for the operation and preventive maintenance of equipment and vehicle.

• Use of watertight dump trucks to prevent mud spilling onto the roads to prevent further odor problem.

• Assign maximum speed limits for vehicle operating at dredging sites and for dump trucks transporting the dredged material.

2) Air Quality and Odor

Dredging activity and transporting of dredged materials during the operations phase will significantly impact air quality and odor concentrations. Worsening air quality and odor may further create negative perception in the community who live close to the dredging locations.

Considering the proximity of dredging activity to residential area, the high intensity of the impact i.e. limited within ± radius 100 m, and the plan to dredge during the night time period, the impacts on air quality and odor require particular attention.


• To expedite the transporting of the dredged materials (dredged sediment and bulk refuse materials) to the designated disposal area on a daily basis.

• The transporting of the dredged materials (dredged sediment and bulk refuse materials) using watertight dump trucks should not exceed the truck capacity to avoid spillage onto the road and carried out during the night time period (e.g. 21.00 to 05.00).

• To avoid spillage onto the road, the trucks transporting the dredged materials do not exceed a maximum speed of ± 40 km/hour.

• To use trucks that are properly maintained and passed emission testing to minimize vehicle emissions.

• To regularly check the watertight cover to avoid leakage.


Dredging will impact water discharge rate of the dredged floodways/drainage canals and waduks. The anticipated dredging volume of ± 2,080,000 m3 will likely to double the floodways/drainage canals and waduks’ capacities. Therefore, the risk of flooding will be reduced. This will be a positive high-intensity and long-term impact not limited to particular dredging site. Environmental management procedure shall be implemented to enhance the positive impact, and manage community expectation and perception.


VI-13


• Providing information and education to local communities in each project location concerning keeping their floodways/drainage canals and waduks clean.

• Regular maintenance of floodways/drainage canals and waduks.

4) Surface Water Quality

Due to the nature of dredging activities, the surface water quality at each location will be impacted in the form of Total Suspended Solid increase. If not managed properly, other environmental components will be affected and may last longer than the dredging period itself.


• This impact is unavoidable due to the nature of the activities, and therefore can only be monitored.

5) Solid Waste

Dredging, separating the dredged materials and transporting of the dredged materials have significant impacts on the amount of solid waste. Without proper management the dredged solid waste will cause environmental disturbance, which consequently will affect community perception. Considering the proximity of the dredged locations to densely populated areas (e.g. residential, trade), this impact requires particular attention.

The impact is of high intensity, limited to ± 50 m radius, and reversible. However, there are potentially other impacted environmental components such as community perception, environmental sanitation affecting communities and workers.


• To collect the dredged materials in order to avoid spillage.

• To expedite the transporting of the dredged materials (both sediment and bulk refuse materials) to the designated disposal areas.

• To assign an environmental sanitation officer at the dredging locations during the JEDI Phase 1 dredging period and to supervise.


1) Employment and Business Opportunities

The operations phase the Phase 1 of the JEDI project that will impact business employment and business opportunities is workers mobilization for


VI-14

dredging, transporting dredged materials, for the disposal area, and office use. In the operational dredging activity, there will be approximately 31-41 persons required for each location. Hiring process will be done by contractors, and will utilize local resources if qualifications and skills meet the requirement. The utilization of local resources will reduce the number of unemployment. This is in line with community expectations during field survey whereby 100% of respondents anticipated benefits from the dredging activities, particularly in relation to flood reduction and employment opportunities. Furthermore, the employment will bring positive impacts in terms of business opportunities for local communities, e.g. canteen/food stalls, etc.

This will be a low intensity impact as few people will be affected in comparison of the population in each dredging site. It is a cumulative impact with other activities around the project and will be continuously ongoing during the operational dredging activity.


• Advertising employment opportunities in the dredging project to local communities through the District and Sub-District Offices and Manpower Offices.

• Prioritizing the employment of local people during the dredging works as along as they fulfill the requirements and qualifications.


Activities within the operations phase of dredging of floodways/drainage canals and waduks in Phase 1 JEDI Project that will affect community perception are workforce mobilization, heavy equipment mobilization, dredging, and transport of dredged material. The impact can either be a direct or secondary impact resulting from worsening of other environmental components such as noise and odor, and disruption to urban infrastructure and facilities.


• Managing the anticipated significant impacts on physico-chemical, biological, and socio-economic, socio-cultural and public health components from each project component activity.

• Continue liaison with community leaders as the dredging activities progress in order to maintain community support.

• Continue to provide information to relevant stakeholders and potentially affected communities throughout the dredging period.

• Advertising employment opportunities in the dredging project to local communities through the District and Sub-District Offices and Manpower Offices.


VI-15

• Prioritizing the employment of local people during the dredging works as along as they fulfill the requirements and qualifications.

• Provide adequate training for staff at dredging sites to operate heavy equipment, to carry out dredging, and to transport dredged material.

• Educate staff to conduct appropriate behavior at dredging sites at all times.

3) Community Order and Security

Activities within the operations phase of dredging of floodways/drainage canals and waduks in Phase 1 JEDI Project that will affect community order and security are heavy equipment mobilization and dredging. The community may be affected in the case of disruptive movements of the equipment due to operator negligence, noise and odor. To anticipate potential disruption to community order and security e.g. theft and vandalism in the project locations, security measures are required.

Particular locations i.e. nearby trading area (Pasar Ular and ornamental fish market) where traffic level may increase significantly due to the activities also require attention.

The impact will be of high intensity and will last during the Phase 1 dredging period. It will be reversible, cover a wide area and affect a large number of people.


• Managing the anticipated significant impacts on physico-chemical, biological, and socio-economic, cultural and public health components from each project component activity.

• Provide adequate training for staff at dredging site to operate heavy equipment and to carry out dredging.

• Provide adequate security at each dredging site.

4) Urban Infrastructure and Facilities

Activities within the operations phase of dredging of floodways/drainage canals and waduks in Phase 1 JEDI Project that will affect urban infrastructure and facilities are mobilization of heavy equipment. The activity can potentially cause damages to urban infrastructure in each location.

Although the impact is limited to areas within each project location and the damage can be repaired, the temporary disruption will affect relatively large numbers of people t.


• Appropriate placement of heavy equipment.


VI-16

• Provide adequate training for staff at dredging site to operate heavy equipment.

• Coordination with relevant stakeholders, including at district and sub-district levels, responsible for urban infrastructure and facilities throughout the dredging period.

6.1.2.3 Impacts on Transportation/Traffic

Activities within the operations phase of dredging of floodways/drainage canals and waduks in Phase 1 JEDI Project that will affect transportation/traffic are mobilization of heavy equipment, dredging and transporting the dredged materials. Such activities can potentially cause an increase of traffic volumes in the vicinity of project locations. Considering high density of traffic at the dredging locations, (V/C ratios at Daan Mogot = 0.82-0.90, at Gunung Sahari = 0.788-0.88, Suprapto = 0.70-0.85, Perintis Kemerdekaan = 0.72-0.94, and Kebon Kacang = 0.74-0.90), the dredging activities in the Phase 1 of the JEDI project will likely to increase vehicle rotation per hour, for 360 days, by 2-8 trucks per hour. Consequently, the increase of traffic can cause deterioration of air quality, increased of noise level, negative community perception and disruption of community order and security.


• Provide notification about the dredging activities at roads that will be and currently affected by the activities.

• Provide notification at appropriate locations in each dredging site to minimize safety risk.

• Assigning a traffic officer at each dredging location.


• Maintain cleanliness of trucks for transporting dredged materials.


• Carry out dredging and transporting the dredged materials during off-peak period.

• Coordination with relevant stakeholders, including at district and sub-district levels, throughout the dredging period.


VI-17

6.1.3 Post-Operations Phase

6.1.3.1 Impacts on Physical and Chemical Components


Maintenance dredging of floodways/drainage canals and waduks in the Phase 1 of JEDI Project will affect the water discharge rate. With maintenance, dredging capacity of floodways/drainage canals and waduks will be maintained and the risk of flooding will be minimized further throughout a period of time. The anticipated dredging volume of ± 2,080,000 m3 will increase the capacities of floodways/drainage canals and waduks. Reductions of number of flooding in each dredging location will consequently have impacts on community perception and public health.

This will be a positive high-intensity and long-term impact not limited to particular dredging site (radius ± 200 m). Large numbers of people and other environmental components will be impacted. Environmental management procedure is implemented to enhance the positive impact, and manage community expectation and perception.


• Providing information and education to local communities in each project location concerning keeping their floodways/drainage canals and waduks clean.

• Routinely cleaning waste in floodways/drainage canals and waduks, and undertake routine maintenance dredging.



Maintenance dredging of floodways/drainage canals and waduks in the Phase 1 JEDI Project will affect public perception towards the dredging activities. The community perception in the post-operations phase is highly dependent upon the success of the Phase 1 Project implementation. If during dredging period, the anticipated negative impacts on physico-chemical, biological, and socio-economic, socio-cultural and public health components i.e. deterioration of air quality, increased of noise level, solid waste, traffic, and community order and security disruptions, are not well managed, the community will perceive the dredging activities with negative attitude. If the negative impacts are successfully managed, the community will perceive the activities with positive attitude.


VI-18

The impact is of medium intensity, throughout the Phase 1 JEDI project duration.


• Managing the anticipated significant impacts on physico-chemical, biological, and socio-economic, socio-cultural and public health components from each project component activity throughout the dredging period.

• To give sufficient notification period prior to workforce release.

• Continue liaison with community leaders in the post-operations phase in order to maintain community support as the maintenance dredging will be a routine activity.

6.1.3.3 Impacts on Transportation/Traffic

The demobilization of heavy equipment required for dredging will affect the traffic flow in each road in the project locations and the surrounding areas as the traffic volume will increase.


• Provide notification about the dredging activities at roads that will be and currently affected by the demobilization activity.

• Provide notification at appropriate locations in each dredging site to minimize safety risk.

• Assigning a traffic officer at each dredging location.



6.2 BASIS FOR ENVIRONMENTAL MANAGEMENT PLAN

Based on the significant impact evaluation results, impact management and monitoring is needed to prevent and minimize the negative impacts and maximize the positive impacts. Environmental Management Plan (Rencana Pengelolaan Lingkungan = RKL) and Environmental Monitoring Plan (Rencana Pemantauan Lingkungan = RPL) provide detailed discussion on the activity components that require management and monitoring.

6.2.1 Objectives of Environmental Management Plan (RKL)

The RKL is prepared to maintain the balance of environmental components in the project area, which will be implemented by:


VI-19

• Preventing, managing and controlling the negative impacts, and enhancing the positive impacts from the dredging activities of floodways/drainage canals and waduks in Phase 1 of the JEDI project.

• Involving relevant institutions in the implementation of the management and monitoring of the dredging activities of floodways/drainage canals and waduks in Phase 1 of the JEDI project.

6.2.2 Approach for the Preparation of the Environment Management Plan

• Institutional Approach

In coordination with relevant components, local government and other institutions, the implementation of regulations and good cooperation with local government requires particular attention, especially concerning the provision of labor and environmental management regulations, i.e.:

Government Regulation (PP) No. 82/2001 on Water Quality and Water Pollution Management.

Governor of DKI Jakarta Decree No. 582/1995 on Establishment of Use and Standard of River Water Quality and Wastewater in DKI Jakarta.

Governor of DKI Jakarta Decree No. 551/2001 on Establishment of Standard of Air Quality Ambience and Noise in DKI Jakarta.

• Economic Approach

This approach uses shall prioritize local employment and advertise work opportunities for residents who live nearby the dredging sites.

• Technological Approach

Technological approach provides a simple and effective alternative of technology application to prevent/minimize the negative impacts, e.g. operating dredging equipment and the types of vehicles used to transport dredged material.

6.3 BASIS FOR ENVIRONMENTAL MONITORING PLAN

As Environmental Management Plan, the Environmental Monitoring Plan is a guideline for the implementation of environmental monitoring in detail. Components being monitored based on the results of significant impact evaluation and environmental management plan.

6.3.1 Objectives of Environmental Monitoring Plan (RPL)

The objective of the RPL is to provide a guideline for the various stakeholders involved in the implementation of environmental monitoring for the


VI-20

dredging activities of floodways/drainage canals and waduks in Phase 1 of the JEDI project i.e.:

• To examine the technology used in the prevention and control of negative impacts in environmental management.

• To reveal if there are any unexpected changes to the environment to ensure effective implementation of impact management.

• To collect relevant data in the case of environmental pollution due the proposed activities in order to prevent it in the future.

Monitored components are based on the impact evaluation results and environmental management plan.

6.3.2 Environmental Monitoring Institutions

Institutions relevant to monitoring activities include:

• DKI Jakarta Regional Environmental Impact Management Agency (BPLHD).

• Environmental Offices of North Jakarta, West Jakarta and Central Jakarta.

EIA of Dredging of Rivers and Waduks Phase 1 (JUFMP/JEDI)

19 August, 2009

Opening by Mrs. A. Endah Wahyuningsih, ST. MT, Environment Management Agency Regional DKI Jakarta Province:

• Development process to be conducted involving participation in environmental management, especially with environmental conditions DKI Jakarta which was already declining.

• Proponent with the assistance of the consultant, authors of the EIA study, is expected to be positive and negative impacts of the plan of activities to be conducted.

• Hopefully with this socialization, community can receive good information of the activity and can be used as a means to provide input so that the proponent can carry out the activity by considering the needs of the people around him.

Presentation of material dredging activities by Ir. Bambang Sigit, MSc, Deputy of the Project Management Unit of the Department of Public Works:

• This dredging activity plan is a very important activity to do improvements include dredging and filling in overcoming the existing flooding problems in Jakarta.

• Dredging will be done in several infrastructures such as drainage channels, flood canals and reservoirs that are under the authority of the Directorate General of Cipta Karya, the Directorate General of Water Resources and administration.

• This dredging process will be divided into two phases, namely Phase I and Phase II. The current EIA study that will be conducted is a study of EIA for Phase I, which includes dredging of sediment in the infrastructure of the West Flood Canal, Lower Angke, Ciliwung-Gunung Sahari, Grogol-Sekretaris, Sentiong-Sunter, Waduk Melati and dredging material transportation to disposal area in Ancol.

• Of the proposed locations mentioned above, the preliminary studies indicated some social problems in areas such as Kali Adem, where there are issues concerning the relocation of 600 people. This lead to the delay of

development process in Kali Angke and Grogol-Sekretaris that caused a few priorities changes of the activity plan in Ciliwung-Gunung Sahari, Sentiong-Sunter, Waduk Melati, Sunter and Cengkareng drain. The first priority will be done on two sites, namely: Ciliwung-Gunung Sahari and Cengkareng or other alternatives and the rest will be done later.

• The Phase II will include Cideng-Thamrin, West Jakarta Flood Canal, Krukut-Cideng, North Sunter Reservoir, South, East III, Kamal, etc.

• Dredging method will be done by accommodating the location and surrounding conditions and also considering the types of activities, the condition of river embankments and bridges, that will be combined in dredging operations plan.

• Efforts to reduce the impact will be performed by the use of jumbo geobag as a sack replacement to place the dredging materials. The material is inserted into the jumbo bag, let to slightly dry and then kept in disposal area at Ancol (for Phase I activities).

• Equipment that will be used will be adjusted to the location of river or reservoir to be dredged, for example for a wide rivers dredging activity will use floating excavator or excavator trench, this equipment will be used as well as for the reservoir area. While for small rivers the dredging activity will use excavators on a pontoon and the existence of bridge. The equipment will be different for each location.

• Transportation of dry dredged materials in the jumbo bag to disposal area in Ancol will be done using trucks that have been covered to prevent material leakage or scattered.

• The process of this activity will be examined further in the EIA study in order to obtain consideration that can reduce the effects of which will be generated from the activity.

Presentation of environmental side of dredging activities by Susanto Kusumahadi, PT ERM Indonesia:

• PT ERM is commenced to prepare the EIA study, in this public socialization will present the dredging activity that will be carried out by the proponent, the Department of Public Works and Government of DKI.

• This activity plan is national and regional concerns due to several locations are under the authority of Jakarta Government, which can be stated that this activity plan is a governmental activity.

• The JEDI activity plan is plan which are usually somewhat different since usually the profit of the activity become the benefits of the proponent, but the JEDI project is a project that will benefit the community with great interest to the affected communities.

• The study of this EIA will be conducted to JEDI Phase I, with a priority to the location of the most urgent. The study will include social and technical issues.

• Dredging process is expected to minimize problems caused by the floods. This can be achieved by active participation from the community as stake holders to contribute and to ensure the sustainability and existence of this infrastructure. This can be achieved, for example by changing the behavior of not throwing garbage into the river so that the government can focus on flood mitigation efforts in Jakarta.

• This socialization process is a must before any activity begins and regulated by Minister of the Environment, Head of Environmental Impact Agency and Governor Decree. This step is to convey information about planned activities in order to gather feedback that can be incorporated into the preparation of EIA documents and included in the Appendix of Terms of Reference document.

• Dredging activities will include five locations and also disposal area of dredged material in Ancol considering the technical reasons, environmental and social impacts.

• Impacts that may arise from these dredging activities include solid waste (the dredged material), transport, odor, and other water quality; these impacts will be assessed further in the EIA study.

Responses and suggestions from participants

a. Dady Arsan, Kamal Muara District Council, North Jakarta

• We welcomed the dredging activities plan to overcome the flood problem in the area, but the bigger concern is tidal flood that happens nearly every month.

• Dredging activity should be carried out in the right procedures therefore the dredged material will not scatter.

• The dredging process and transportation schedule should be conducted in such manner so that it will not interfere daily activity of the surrounding community.

b. Muh. Amri, Forum Pemukiman Jakarta

• Suggestion to use public service ad slots in private television to broadcast the information. This had been already used by the Office of Population and Civil, City Administration Office etc.

• The proponent should provide a hotline number in each dredging location that can be accessed by the public.

• Explanation of Governors Regulation No. 28 of 2009 concerning EIA, is still relevant for this dredging activity.

c. Mat Sani, North Kedoya District Council

• Boundary aArea of Kali Sekretaris, is the Kali Pesing Koneng area market will also be dredged.

• The Kali Pesing-Kali Angke had changed its name to Karimun Kepar, with a width of 25 m and 7 meters, the height limit now is about 1 meter and never been dredged before.

d. Chairil Anwar, Karang Anyar District Council

• Dredging activity along the Ciliwung- Gunung Sahari in Kartini area should pay attention to the activity of fish traders during the day and food stall at night.

• The efficiency of the activity, consider there is drying process of dredged material, so that it will not to disrupt the activities around it, for example schools and channels construction around Jl. Kartini.

e. Ahmad Dahlan, Dekel Ancol

• Related to the management in order not only to build but more importantly to maintain the infrastructures, the socialization of these activities has often done and hopefully people participation can be actively carried out.

• Dredging will be conducted in low areas, beside the concern of depth of the river, is there any embankment construction activity.

• In impact assessment section, maintenance issue is not listed as discussion matter in EIA documents.

• Ancol area not only received but also experienced tidal flooding, assessment and consideration of the impact that will occur due to Ancol as dredging material storage areas should be made in the activity planning.

• The socialization of this activity should be made until the lowest level i.e the village community.

• So that the plan is not only effective to manage the flood problem but also have an added value to the surrounding community, the area near the reservoir can be converted to a recreation site.

• Please advice the timeline of the cancelled reservoir development plan.

f. Iman Rohadi, Rawa Buaya District Council

• Some time ago in Cengkareng drain dredging has been done, but the dredged material is still pilled up in the Kel. Rawa Buara near the Pertamina area. Is this a draining process period? It is expected not to happen in the JEDI process.

• The existing inspection road in Cengkareng Drain is in damaged condition, Coordinated with the associated institution if the damage is repaired so that the activities will not damage the repaired roads.

g. Erman, Mangga Dua Selatan District Council

• At present time flood occur in the Ciliwung tributary, but it is not included in the dredging plan, why.

h. Jarkoni, Sunter Agung District Council

• Basically the community is gladly respond to the dredging plan, but because it involves two villages in the area please the socialization is conducted to officials and residents in both villages so that they knew about the plan of activities to be conducted.

• There are economic activities near the dredging location, please conduct socialization in such manner so that the activity will not disrupt the traders.

i. Sukirno, Community of Ancol District

• This project is a good step, and is an implementation of the Governor of Jakarta promise to overcome the flood.

• From what allocation is the source of funding for this activity, is it from regional budget, national budget or loans from foreign financing institution

• What is the impact of approximately 2 million cubic meters sediment transportation?

• Technical implementation, problems occur with contractors and director, lack of coordination and information with village/community official.

• The delay of reservoir development plan should be informed further to the public

j. Irianto, KLH Central Jakarta

• In impact assessment, please put on the initial depth and the depth after dredging.

k. H. A. Sangir, Dekel Bungur

• When will this project conducted?

• Sustainability of the project, because in the Bungur area flow Kali Baru, tributary of Sentiong River, which flood in the rainy season.

l. Fera, Central Jakarta

• When dredging conducted during the rainy season the water level will be increased, and will disrupt the dredging process.

m. Bambang S, Kebon Kosong

• Is dredging program have its certain schedule, because in each district there is fund for river normalization

• Dredged material disposal to coastal area in Ancol, will there be an impact on reclamation and mangrove

• Sediment in the dredging location comes from domestic waste and garbage disposal directly to the river or from garbage dump that located near the river, while there are rules and clear sanctions about the action, no action and follow-up come from the officers. Are this garbage dump will be dredged also.

n. Bangsa Malau, Rawa Badak Selatan District Council

• Before the socialization to the community, the contractor should field survey, because in our area there are several populated areas that can not be passed by vehicle

• Anticipation assessment of contractor work in terms of dredging procedures and dredging material disposal.

• Is Rawa Badak Reservoirs similar with East Sunter Reservoir

• The impact of the activities associated with the preparation of Adipura assessment.

The response from the proponent and the EIA Consultant

• Grogol-Sekretaris-Angke included in West Flood Canal was originally the first priority, but based on results of preliminary studies that mention a social problem in Kali Adem concerning relocation of approximately 600 people who previously had been relocate but have returned to the same location. The problem is caused delayed in dredging activities of Grogol-Sekretaris-Angke which will go into the West Flood Canal.

• Ciliwung-Gunung Sahari is the first priority, with the information regarding trading activities near the site and also found bridges across the river, the dredging method will be conducted using the appropriate equipment, including floating bulldozers that currently used in the pilot project. For the draining process of dredged materials, they will not be placed on the ground but in decks.

• JEDI activities will use standards that can be implemented by local contractors, because this activity is the beginning of a routine activity in the future.

• For Ancol, the activities of flood prevention activities will be carried out in several stages; first stage is the dredging and sea defense to cope with abrasion from the sea. There are suggestions from the community to build a sea dike in the north of Jakarta, but this needs to be considered carefully concerning the impact that will occur to harbor line and marina, and the drainage system of flood water from the mainland to the sea. Even though there is example implemented in Singapore by using water gauge equipped with a pump in every river but I will be costly.

• Socialization in village level will be discussed with the consultant.

• Design review and EIA study of Ancol disposal site has been completed. Currently is waiting for the implementation. The dredged material that will be disposed is already packed in bags so that the possibility of scattered will be suppressed. This plan has been discussed further with the authorities Ancol.

• Regarding existing activities in Jl. Kartini, these points will be documented in the EIA study and documented in the EIA document, although the mitigation plan has been described by the proponent.

• Impact of dredging location up to dredged material disposal will assessed in JEDI EIA, but at the time the material placed into the disposal area in Ancol, the impact will be assessed by another EIA, The Ancol EIA, so that there will be a clear differentiation of responsibilities to ensure the prevention of impact is well handled by the appropriate parties.

• Maintenance as post activities is conducted to ensure that the activity can be beneficial for the long term.

• The project is funded by a $ 150 million loan from the World Bank, the proposal currently is being prepared.

• The five location is included in the first stage. The EIA consultant is ERM. There will be another consultant to assess EIA of the remaining locations.

• The 2 million cubic meters is the volume of the first phase; the overall volume of sediment disposal is as much as 8-9 million and will be placed in Ancol and if possible be disposed in Muara Kali Adem and also in near the estuary area of East Flood Canal in Marunda.

• Transportation schedule will be limited to the amount of rotation and the volume transported.

• Technical implementation will be regulated by the local government administration and other PMU so that the activity will be well informed to the public up to the village and district level.

• Reservoirs are not under DKI Jakarta administration, dredging activity gradually will be implemented to reservoir to the dam.

• The design is in the finalization process, the depth of the river is also under study, so that the volume mentioned in the presentation is still an estimate.

• Tributaries that will go into the rivers of JEDI projects will be handled by each regional administration in DKI Jakarta in a different EIA. This is a preparation for loans proposal submission to the World Bank that hopefully could be realized in the middle of next year.

• Different characteristics of the river will be affected to the equipment and method used in the dredging process so that each location will have specific methods and timeline.

• For the implementation of the first phase of JEDI, DKI Jakarta government have secured an agreement with Ancol regarding the Confined Disposal Area with clay liner, for dredged material that have been packed in the bag that later can be used for expansion of reclamation.

• The main origin of river sediment comes from the domestic waste and garbage, the dredging process will not stop once the first phase is finished but will become a routine activity.

• Notification to carry out socialization will be inform to authorities such as Directorate General of Cipta Karya, DKI Jakarta administration, and SDA to be forwarded to the contractor listed in the contract.

• The rivers that were impassable by car will use a small tool or other alternative will be sought

• The calculation of the volume will be easier with the inclusion into the sack and also can reduce the impact of scattered during transporation.

• Reservoir Rawa Badak is Sunter III Reservoir and was included in the JEDI program

• In connection with Adipura, dredged material will be placed in bags and allowed to seep to avoid scattered.

Document authorizer: Dr. K. Susanto Kusumahadi

II. Suggestions, Feedback from the DKI Jakarta Province AMDAL Assessment Commission Team

1. Ir. Hesti Nawangsidi a. The DKI Jakarta river and dam activities are categorized as an urgent/emergency project, related to flood control efforts in Jakarta. Therefore, the required AMDAL studies should focus on the “urgent” nature of the activitiesconcerned.

b. Areas of Urgency: Time frame of the dredging activities. There has been no explanation of

the time span or timing of the dredging activities or of the transportation to the disposal area for the 5 dredging locations. The ANDAL TOR statesthat the technical feasibility study is being prepared. However, becausethe technical feasibility study is under review, the ANDAL TOR should provide long term design initiatives that are more appropriate for the dredging, draining, and transportation activities, with regards to rainfall patterns, puddling and flooding conditions, tidal flood, traffic patterns, amongst others concerns.

Rainfall data from II.33 shows that the months from December to February have the highest rainfall. January to February generally experiences puddles and tidal flood. In these conditions, there is a need to consider how the sorting, draining, and transportation activities may or may not be conducted.

c. Based on Figure II.11, the resultant materials from the dredging ofCengkareng drain are not disposed of in the West Ancol area. There is no information about this so far. If there are no plans, then environmental impact studies on the water surrounding the dredging disposal sites must be done.

d. The ANDAL TOR appears too conservative, as it reviews many aspects but lacks focus on the dredging, sorting, Geobag draining, or transportation. Although the technical feasibility study is being conducted, the ANDAL TOR should include an inventory area around the river and the dam segments to be dredged, so that it can be used to sort, use Geobags, and so on.

e. It is recommended that the ANDAL TOR include more focus on the impacts of the events and activities that are relatively clear: the procurement of dredging equipment, dredging, sorting, Geobag use, and transportation. The activities are not widespread but are localized and intense, because the amount to be dredged totals about 2 million m3. The scope and methods must be adjusted, so they do not include studies are not that relevant.

2. Drs. Ramdhan a. Information was explained by the study authors b. Explanation of the scope of unfinished activities c. Information about employment such as what? d. Questionnaire (social issues) are reviewed

e. Methodology is tailored to the repair of environmental damagef. Correction/clarification: A quantitative approach not quantity, triangulation is without observation g. The number of samples has not been determined

3. Ir. Suryadharma a. Explanation of job description is unfinished (dredging s/d landfill) b. Scope is to be reviewed, with just observing primary impactsc. Rona environment: completed with measurements of the mud qualityd. The delineation of each study site should give an explanation/description (not just a display of images)

4. Dr. Melati Ferianita a. There needs to be an explanation of the structure/construction of the Disposal area/dumping site, for the dredging. b. Analysis needs to be done on the quality of the resultant dredged mud c. There needs to be an explanation of the transportation system to the disposal area locationd. How will rainfall events in the rubbish/mud TPS area be anticipated?

5. Bureau of Planning and the Environment: a. Treatment of the city infrastructure has not been informed b. Implementation schedule has not been clarified, whether it will occur simultaneously or in stages c. Laboratory test results are not yet includedd. Transport routes to the dumping site location has not yet been informed

6. Prov. DKI Jakarta Sanitation Office: Waste management will be discarded (not dumped) – how and who will execute this? Need this information in order to explain the mechanism

7. KLH North Jakarta: a. With regards to the activities interacting with the community, what is it’s management impact (economics)? b. Traffic problems particularly at Jl. RE Martadinata need more attention

8. KLH West Jakarta: There is not to be material buildups on the edge of the road

9. South Mangga Dua Kelurahan: It is recommended that if field surveys are conducted they be done on weekdays and they coordinate with local community elements (District Council)

10. Prevention of Field Impacts and PSDP: Should be equipped with information to estimate the amount (volume) of

run off that will be reduced, as a positive impact of these activities Information should be provided about traffic problems to be complete

11. World Bank: a. General: ANDAL TOR for the dredging project plan phase 1 JUFMP is generally accepted as in accordance with the guidelines of World Bank policy OP 4:01

Environmental Studies. It is expected that the ANDAL study, RKL and RPL will be arranged to meet the requirements of OP 4:01 Environmental Assessment in relation to the determination (appraisal) of the acceptance of the World Bank loans for the JUFMP projects.

b. Alternative Study (Assessment of Alternatives): The TOR explains that there are no alternative studies in the preparation of the environmental assessmentstudy (ANDAL). Indonesia Regulation (MoE No. 8 of 2006) and the World Bank's Policy Manual OP 4:01 requires alternative studies in environmental impact assessment studies. Activity components should have several alternatives, such as alternative locations, designs, transportation, transportation routes, methods, processes and support facilities, etc. Alternative studies can be explored for the alternatives that are originally planned or generated during the EIA study. OP 4:01 specifically requires that the study also include alternatives for 'no project' or without the project. This must include predictions of what couldhappen if the dredging activity plan is not carried out. Important aspects to consider are also the possibilities of community or private sector reactions if the dredging activities are not conducted.

c. Institutional aspects: The TOR should identify the capacity of institutions to implement the environmental assessment recommendations by conducting a review of the responsibility and capacity of the agencies and institutions, and recommend steps to strengthen or increase their capacity so that the management plan and environmental monitoring can be implementedappropriately with the environmental assessment (ANDAL). Examples of recommendations can be extended to setting inter-sectoral organization rules, management procedures, management of personnel structure, and financial management.

d. RKL and RPL: The management plan for this project must (a) identify the actions (responses) against potential negative impacts; (b) determine the agreements/guidelines (requirements) to ensure that such actions are done effectively and in the appropriate time, and (c) discuss the efforts that need to be done to reach these agreements. Environmental monitoring will provide key environmental aspect information about the project, particularly the environmental impacts of the project and the effectiveness of mitigation measures. This information will assist the project team in evaluating the success of mitigation measures as part of project supervision, and can provide room for corrective actions when needed. Environmental monitoring will include: (a) specific descriptions and technical details about the actions or plans, including monitoring parameters to be measured, methods to be used, sampling locations, monitoring frequency and a definition of the limits that indicate corrective action needs to be taken; and (b) monitoring and reporting guidelines that will (i) ensure early detection of conditions that require mitigation measures or specific management, and (ii) complement the information about the progress and management of the results.

e. RKL integration in the project: It is expected that the identified plans are specific enough in the description of the management and monitoring plans, and

in the assignment of responsible institutions; the plan should also be integrated into the overall project planning, design, finance, and implementation. This integration can be achieved by including the RKL and RPL documents in the project documents so that the plans mentioned above will be budgeted in terms of costs, supervision and other components of the project.

f. Public Participation: Directing AMDAL coordination with other government agencies in obtaining the views or perceptions of the groups affected by the project, and documenting all meeting activities, communications, opinions, input, and positions.Consultations need to be prepared as early as possible. For Category A World Bank projects (as apply to the JUFMP project), proponent party consultation with the project-affected groups must be done at least 2 times including (a) after environmental screening and before the ANDAL TOR are finalized and (b) whenthe drafts of the ANDAL, RKL and RPL are arranged. To accommodate theANDAL-related topics that will impact on these groups, consultations should also be done during project implementation, if necessary. Copies of meeting notes should be attached to the main ANDAL document.

g. Information regarding Community: The draft ANDAL document must be available in public locations in a form and language that is understandable and accessible to the community groups affected by the project and local NGOs. An executive summary of the ANDAL must be translated into English for theinformational benefit of the World Bank Infoshop.

DKI JAKARTA PROVINCE AMDAL ASSESSMENT TECHNICAL TEAM DISCUSSION MINUTES

Day/Date: Thursday/16 September 2009 Time: 13.00 WIB - finish Venue:BLPHD Meeting Room, Nyi Ageng Serang Building, Floor.10, Jl.HR Rasuna Said, Kav.C.22, Kuningan, South Jakarta

No. Description of issues to be Addressed Answer Page

Ir. Hesti Nawangsidi1. The DKI Jakarta river and dam activities are an urgent /emergency

project since it is related with flood control effort in Jakarta. Therefore, the required AMDAL study must focus on the ‘urgent’ feature from respective activity.

The amdal study which is going to be prepared will focus on the activity urgency.

2. The urgencies are related to:- Dredging activity time frame. There has been no explanation on

duration or dredging activity time frame and also the transportation to disposal area for the 5 (five) dredging locations. It is stated at ANDAL TOR that technical feasibility study are being prepared. Since the technical feasibility study is being prepared, ANDAL TOR should offer the initiative for scheming the more accurate duration for dredging, draining and transporting, associated with rainfall pattern, flood and inundation condition, rob, traffic pattern and so on.

- From rainfall data on page II.33, it is shown that December-February is the months of highly rainfall. In general January-February experiences inundation and rob. At such condition, whether the separation, draining, and transporting activity are able to be conducted should be considered.

- Since t ANDAL TOR document and technical design are prepared at the same time, so the detail schedule could not be presented in TOR document. The detail dredging implementation activity and transporting to the disposal area to the 5 (five) dredging areas will be delivered in the ANDAL document.

- The separation, draining, and dredging material transporting during wet season (inundation and rob) will be considered at Andal, RKL, and RPL study. The explanation has been included in the TOR document.

Page II-22

Page II-19 to II-20

3. Based on figure II-11, the resultant materials from the dredging activity of Cengkareng Drain are not disposed to West Ancol disposal area. There has not been information regarding such thing. If there is no plan, it is necessary to undertake the impact study on water body in the vicinity of dredging disposal location.

The meaning of Map II-1. Disposal area location for Cengkareng Drain dredging resultant will be disposed in West Ancol with the other 5 (five) locations.Map II-1 has been corrected.

Page II-12

4. The proposed ANDAL TOR appears so conservative, too many aspects to be studied, but it lacks focus on the dredging, separating, draining and transporting. Although the study about

technical feasibility is being conducted, it is better if ANDAL TOR has had the inventory on the vicinity area of the river and dam which will be dredged. Therefore it that can be used for separating, filling the geobag and so forth.

and dam location which will be dredged as the result of the team early survey has been included and will be explained in more detail in the andal document (after field survey has been conducted).

5. It is recommended that ANDAL TOR more focus on the relatively obvious activity impact such as: dredging equipment provision, dredging, separating, filling geobag, and transporting. Those activities are not wide-ranging, instead of localized but intensive, because the area that will be dredged is about 2 million m3. The scope and method must be adjusted, so they better not to include studies that are not relevant.

The activity description and activity impact that will be studied have been focused according to the main activity of the project (dredging equipment provision, dredging, separating, filling geobag, and transporting).The scope and method have been corrected.

The alternative study has been included. Page II-24 to II-25


Manual OP 4:01 requires alternative studies in environmental impact assessment studies. Activity components should have several alternatives, such as alternative locations, designs, transportations, transportation routes, methods, processes and support facilities, etc. Alternative studies can be explored for the alternatives that are originally planned or generated during the EIA study.

- OP 4:01 specifically requires that the study also include alternatives for 'no project' or without the project. This must include predictions of what could happen if the dredging activity plan is not carried out. Important aspects to consider are also the possibilities of community or private sector reactions if the dredging activities are not conducted.

FOREWORD

Project Management Unit (PMU), Directorate General of Water Resources, Ministry of Public Works as the implementing agency for the Dredging Works for Rivers and Waduks in DKI Jakarta in Phase 1 of Jakarta Urgent Flood Mitigation Project/Jakarta Emergency Dredging Initiative Project (JUFMP/JEDIP) is committed to achieving sustainable development.

The environmental impact assessment has identified significant impacts of dredging activity, both in the operational and post operational stages, which need to be managed to achieve the highest level of environmental protection. Efforts towards the management of these impacts are described in detail in the Environmental Management Plan (EMgP / RKL = Rencana Pengelolaan Lingkungan) and this Environmental Monitoring Plan (EMnP/ RPL = Rencana Pemantauan Lingkungan).

RKL and RPL are expected to prevent and/or minimize the anticipated negative impacts, and to enhance and/or maximize the anticipated positive impacts.

We thank the DKI Jakarta technical team and AMDAL committee, and all related parties, for their cooperation that has allowed for the completion of the RKL and RPL.

CHAPTER IINTRODUCTION

1.1 BACKGROUND


The magnitude of the impacts caused by annual flooding in the Capital City has become a national issue due to the large financial losses and the impact on communities in the Jakarta area. To reduce the magnitude of the losses and damage caused by the floods, the Government of Indonesia has identified a series of flood control drainage canals, floodways and retention basins (waduks) that require urgent improvements. The rehabilitation of these structures will reduce the risk of flooding and bring direct benefits to the more than one million people who live and work in the areas prone to flooding.

The Indonesian Government has requested a loan from the World Bank to finance the dredging and rehabilitation of the majority of the existing drainage system in Jakarta. One of the proposed projects is the Jakarta Emergency Dredging Initiative (JEDI) as included in the Jakarta Urgent Flood Mitigation Project (JUFMP), which aims to reduce sediment deposits in the flood channels. These sediment deposits have reduced the design capacity of the drainage canals, floodways and waduks by half.

One of the JEDI Project activities is the dredging of 16 drainage structures. The project proponents, the Directorate General of Cipta Karya (DGCK) and the Directorate General of Water Resources (DGWR, Sumber Daya Air = SDA) Department of Public Works, and DKI Jakarta Government, have responsibility for:

1) Three drainage canals of national importance under DGCK authority: (i) Tanjungan, (ii) Lower Angke, and (iii) Cideng-Thamrin.

2) Three floodways under DGWR authority: (i) Cengkareng, (ii) West Banjir Canal; and (iii) Sunter.

3) Five drainage canals under DKI authority: (i) Ciliwung-Gunung Sahari, (ii) Sentiong-Sunter, (iii) Grogol-Sekretaris, (iv) Pakin-Kali Besar-Jelakeng, and (v) Krukut.

4) Five retention basins (waduks) under DKI authority: (i) Pluit, (ii) North Sunter, (iii) South Sunter, (iv) East Sunter III, and (v) Melati.

For Phase 1 of the JEDI Project, 5 (five) drainage canals/floodways and one waduk have been selected to assess the planning, technical design, and environmental management approach to be implemented in all project sites. These sites have been selected because they are expected to produce relatively small environmental and social impacts; however the dredging work must meet one of the project activity’s main objectives, and must be significantly beneficial towards the flood prevention efforts. The sites included in Phase 1 of the JEDI Project are:

1) Cengkareng Floodway.

2) Ciliwung - Gunung Sahari Drainage Canal.

3) Sentiong – Sunter Drainage Canal.

4) Sunter Floodway.

5) Waduk Melati.

Based on the Environmental Impact Statement (ANDAL) the Dredging of Floodways/Drainage Canals and Waduks Phase 1 JEDI, it is predicted that there will be significant impacts on the physico-chemical, biological and socio-economic components and therefore an Environmental Management Plan (RKL) and Environmental Monitoring Plan (RPL) are necessary to provide additional guidelines for the project activities and subsequent environmental management and monitoring efforts. This is to be executed by the project proponent, with regards to all environmental preservation activities, as outlined in Law No.32/2009 regarding Environmental Protection and Management.

This Environmental Monitoring Plan (RPL) was developed in accordance with the management activities outlined in the Environmental Management Plan (RKL), to be used to identify and evaluate the management measures that are implemented. It is also to be used to provide feedback to the project proponent and other related agencies/institutions/parties, to prepare guidelines for environmental management and monitoring policies.

1.2 POLICIES ON ENVIRONMENTAL MANAGEMENT IMPLEMENTATION

Environmental management is a holistic effort to preserve the environment function. For this project it involves environmental policy, utilization, anddevelopment, maintenance, rehabilitation, monitoring and control. Managing the environment is a joint responsibility between the government, community and the private sector. Proper understanding of the sharing of responsibility is critical to the success of environmental management in all areas of Jakarta. Various studies have reported a decrease in the quality of the physical environment in Jakarta, a result of environmental destruction and pollution.

Since the establishment of the Environmental Management Act No. 23/1997, the Government has committed to promote sustainable development policies. Sustainable development is an environmentally-conscious, transparent and planned effort that integrates the environment and its resources in the development process to ensure the capability, well-being and quality of life of present and future generations. Therefore, it is important to understand the function of natural resources and prioritize the classification of natural resources that must be preserved, particularly air quality, water quality and biodiversity. Additionally, development must, in principle, become the driving force behind the creation of employment opportunities, income generation and improvements in health.

Accordingly, there are several environmental management policies that are relevant to dredging of floodways/drainage canals and waduks Phase 1 JEDIi.e.:

a) Maintenance of the balance between the natural and built environment.

b) Traffic management.

c) Minimization potential environmental pollution due to the dredging activities e.g. noise and odor pollution.

d) Attempts to balance the interactions between project activities and thesurrounding environment, particularly community social interactions.

DREDGING OF FLOODWAYS/DRAINAGE CANALS& WADUKS PHASE 1(JUFMP/JEDI)

[ I-1 ]

CHAPTER IINTRODUCTION

1.1 BACKGROUND


The magnitude of the impacts caused by annual flooding in the Capital City has become a national issue due to the large financial losses and the impact on communities in the Jakarta area. To reduce the magnitude of the losses and damage caused by the floods, the Government of Indonesia has identified a series of flood control drainage canals, floodways and retention basins (waduks) that require urgent improvements. The rehabilitation of these structures will reduce the risk of flooding and bring direct benefits to the more than one million people who live and work in the areas prone toflooding.

The Indonesian Government has requested a loan from the World Bank to finance the dredging and rehabilitation of the majority of the existing drainage system in Jakarta. One of the proposed projects is the Jakarta Emergency Dredging Initiative (JEDI) as included in the Jakarta Urgent Flood Mitigation Project (JUFMP), which aims to reduce sediment deposits in the flood channels. These sediment deposits have reduced the design capacity of the drainage canals, floodways and waduks by half.

One of the JEDI Project activities is the dredging of 16 drainage structures. The project proponents, the Directorate General of Cipta Karya (DGCK) and the Directorate General of Water Resources (DGWR, Sumber Daya Air = SDA) Department of Public Works, and DKI Jakarta Government, have responsibility for:

1) Three drainage canals of national importance under DGCK authority: (i) Tanjungan, (ii) Lower Angke, and (iii) Cideng-Thamrin.

2) Three floodways under DGWR authority: (i) Cengkareng, (ii) West Banjir Canal; and (iii) Sunter.

3) Five drainage canals under DKI authority: (i) Ciliwung-Gunung Sahari, (ii) Sentiong-Sunter, (iii) Grogol-Sekretaris, (iv) Pakin-Kali Besar-Jelakeng, and (v) Krukut.


[ I-2 ]

4) Five retention basins (waduks) under DKI authority: (i) Pluit, (ii) North Sunter, (iii) South Sunter, (iv) East Sunter III, and (v) Melati.

For Phase 1 of the JEDI Project, 5 (five) drainage canals/floodways and one waduk have been selected to assess the planning, technical design, and environmental management approach to be implemented in all project sites. These sites have been selected because they are expected to produce relatively small environmental and social impacts; however the dredging work must meet one of the project activity’s main objectives, and must be significantly beneficial towards the flood prevention efforts. The sites included in Phase 1 of the JEDI Project are:

1) Cengkareng Floodway.

2) Ciliwung - Gunung Sahari Drainage Canal.

3) Sentiong – Sunter Drainage Canal.

4) Sunter Floodway.

5) Waduk Melati.

Based on the Environmental Impact Statement (ANDAL) the Dredging of Floodways/Drainage Canals and Waduks Phase 1 JEDI, it is predicted that there will be significant impacts on the physico-chemical, biological and socio-economic components and therefore an Environmental ManagementPlan (RKL) and Environmental Monitoring Plan (RPL) are necessary to provide additional guidelines for the project activities and subsequent environmental management and monitoring efforts. This is to be executed by the project proponent, with regards to all environmental preservationactivities, as outlined in Law No.32/2009 regarding Environmental Protection and Management.

This Environmental Monitoring Plan (RPL) was developed in accordance with the management activities outlined in the Environmental Management Plan (RKL), to be used to identify and evaluate the management measures that are implemented. It is also to be used to provide feedback to the project proponent and other related agencies/institutions/parties, to prepare guidelines for environmental management and monitoring policies.
