Safeguards monitoring (Environment), (vi) reports on the implementation of the environmental mitigating measures and the environmental management and monitoring plans specified in the IEE and EMP are submitted to ADB on an semi-annual basis. This report also corresponds with the IEE, Appendix F Sample Mitigation Compliance Inspection Monitoring Form, and Appendix G Sample Project Environmental Progress and Monitoring Report. PT PLN (Persero) has assigned the Joint Venture of Tractebel Engineering Ltd. and Power Grid International Limited (Thailand), Contract No PJ/041/DIR/2013 of 30th July, 2013, to carry out the monitoring of the project works. The project comprises of design, supply, installation, testing, and commissioning of the works as follows: a) Package 1: 275 kv Transmission Line between Bengkayang substation and the border with Sarawak, East Malaysia (80.26 km). b) Package 2: 275/150 kv Substation at Bengkayang. c) Package 3: 150 kv Transmission Line from Bengkayang substation to the new Ngabang substation (93.34 km), and from there to the existing Tayan substation (46.64 km). d) Package 4: 150/20 kv Substation at Ngabang and Tayan Substation extension. The location of the project is presented on Map 1 and the West Kalimantan Power Grid Strengthening Project is presented on Map 2. The monitoring of the environmental works is carried out for all four packages of the works as mentioned above. Compared to the original schedule mentioned in IEE, there are some route changes due to the relocation of the planned sites for 275/150/20 kv Bengkayang substation and 150/20 kv Ngabang substation. The status report concerning the route changes is presented in Appendix According to the original plan the 275 kv Bengkayang Jagoibabang Transmission Line (Sarawak border) comprised of 199 towers (Tower No 1 in Bengkayang to Tower No. 199 in Jagoibabang). Six towers from No. 1 to 6 had been eliminated, and 4 towers had been added. Moreover, there are an additional 4 intermediate/insertion towers required thus in total there are 201 towers. 2. According to the original plan, 150 kv Bengkayang - Ngabang and 150 kv Tayan - Ngabang transmission line routes comprise of 393 towers (260 towers and 133 towers respectively). There are several modifications to the total number of towers for the Bengkayang Ngabang and Tayan - Ngabang transmission lines to increase to 408 towers (280 towers and 128 towers respectively) as follows: a) Bengkayang Ngabang route The shifting of 275/150 kv Bengkayang Substation to north-eastern direction resulted in the elimination of 3 towers and addition of 7 new towers. Due to site relocation of 150/20 kv Ngabang Substation to south of Ngabang and thus closer to Tayan direction, a number of towers will be relocated and added: Relocation: 7 towers (T.253 up to T.259) Addition: o 3 additional towers (T.260 up to T.262) to connect with the former Ngabang - Tayan route at tower T.128 Page 1 of 71 Fifth Semi Annual Report on Environmental Issues (30/6/2016)

9 o o 13 additional towers as relocated towers from former Ngabang - Tayan route of towers T. 128 up to T additional towers to connect with tower T.116 of former Tayan Ngabang route with the (New) Ngabang substation. There are two towers (T.157 and T.159) to be eliminated due to span condition and one additionally inserted tower (T.24A). b) Ngabang Tayan route The Tayan - Ngabang route has been modified as follows: 5 eliminated towers of former Ngabang - Tayan route at towers T.129 up to T.133, because the Bengkayang Ngabang route will be connected with T eliminated towers which formerly belonged to the Ngabang - Tayan route from towers T. 128 up to T.116 but are now part of the Bengkayang - Ngabang route. Two additional towers (T.114B and T.114C) are required to connect with the remaining planned towers from Tayan direction. The original tower T.115 will be shifted from previous planned location (the number will become T.114A). 9 towers are required to connect to Tayan substation which had been shifted about 2.5 km southward during the planning of 150 kv Tayan-Siantan (Pontianak) transmission line. This route has not been mentioned in the original tower schedule of 150 kv Tayan- Ngabang transmission line. Two additional towers as insert tower at T.04A and T.73A Thereby the Bengkayang Ngabang Tayan transmission lines will comprise of about 408 towers, i.e. 280 towers for the Bengkayang Ngabang section and at least 128 towers for the Tayan - Ngabang section. Detailed information concerning environmental review on relocation of the substations and towers is elaborated in detail in Appendix 5. Map 1.

Local contractor as subcontractors and local people as labour were hired. 3. ENVIRONMENTAL MITIGATIONS AND LAND ACQUISITION IMPLEMENTED 3.1. Environmental Mitigations a) Air Quality: Air quality deterioration could be caused by exhaust gas of construction vehicles (truck, car, motor cycle), operation of concrete mixer, drilling/pilling machineries and heavy vehicles for land preparation (mostly utilized for substation areas; for tower sites it is very rare). Concrete mixer: For concrete pouring of each tower pad, contractor applied small unit of concrete mixer for intermittent use for about 2-3 hours a day (in average 8 machinedays) to complete concrete pouring for the foundations of each tower. Mostly, it generated insignificant impact on air quality due to short duration and most towers are located away from dwelling areas. Drilling and excavation: Contractor applied high intensive manual labour for excavation of tower pads so no air pollution for this activity. Drilling holes for concrete piles was conducted for the tower site with low bearing capacity of soil. In wet soil drilling machine was used, while in the dry soil manual drilling was used. In the tower site with good soil condition no drilling to be conducted. The air pollution impact due to drilling was considered moderate. Erection of towers: Contractor applied manual winch/pulley for elevating the assembled steel member of tower erection development. No machinery used, so there is no air pollution. Transportation of material. From warehouse to roadside near the sites, contractor applied trucks in good condition. Air quality deterioration caused by the fugitive dust can be neglected because there were no significant fugitive dust. From roadside to tower sites, contractor mostly used labour and motor cycles or used small trucks wherever possible. Air pollution was very small and dispersed. Land preparation of the substations. The land preparation was conducted at Bengkayang and Ngabang substations but not for Tayan substation (the site had been ready). The original area was undulating land, so it needed soil works to level the site. The higher soil level was excavated to fill the lower level using bulldozer and backhoe. No quarry from outside was needed for the embankment, all soil for embankment comes from the same area, in consequence no truck was going in and out to public road or other places concerning this activity, thus there was no fugitive dust in the surrounding area during the land preparation. b) Water Quality Water quality deterioration could be caused by soil works, concrete works, oil spill (oily water). Soil works may generate sedimentation and turbid water in water body. In tower pad area, where the excavation encountered the soil acid in nature, it also may produce acid water. Concrete works usually produce alkaline water and turbid water due to the cement Page 13 of 71 Fifth Semi Annual Report on Environmental Issues (30/6/2016)

21 deposit. Oil spill could occur due to negligence, misconduct and accident, further it may cause oil pollution on soil and later oily water in water body. Drillings and excavations. In area of tower pad where the soil is classified as soft soil it shall be drilled to develop holes for concrete piles. Where the soil was considered good enough, no drilling was applied. Excavation was conducted in all tower pads with varied dimension, depending on topography and type of tower. The drillings and excavations generated muddy soil and brown water with high soil sediment. When it rains, and no barrier exists, the bare soil and soil sediment may wash away. In general, the contractor did not apply the protection measures to trap the sedimentation. Fortunately, most towers are located in areas where natural sediment screening is provided by grass, bushes and litter of foliage. In general this activity generated insignificant soil erosion. At the time being, there was no suspected acid sulphate soil, so no acidity soil and water pollution happened. Land preparation. The land preparation of Bengkayang, Ngabang and Tayan substations cover an area of about 6.6 ha, 1 ha and 1 ha respectively. The areas are undulating and needed soil works to level the sites. The higher soil level was excavated to fill the lower level using bulldozer. Bare land may cause soil erosion and sedimentation, but fortunately there is no creek nor river in the adjacent area so sediment settled in the substation areas. To protect soil from land slide and erosion, a retaining wall covering the entire boundary area was constructed at Bengkayang substation.. At Ngabang the retaining wall in the surrounding boundary areas have been constructed. The drainage water siphon has been repaired so no flooding anymore in the adjacent area. An open drainage ditch was constructed between main road and substation so that there is no flooding of the road anymore. The same applies to the adjacent area behind the control building. At Tayan substation the required retaining wall was completed. Concrete works. Most impact of concrete works usually happens during the cleaning/washing of the concrete mixer machine and other apparatus. It produces alkaline water and turbid water due to the cement deposit. In many instances, contractor dumped the waste water on ground within tower area. Due to small volume of each event, the waste water could be easily absorbed by the soil in the tower s area. There was insignificant impact caused by this activity. Oil uses. Other than transportation of material for the construction works of each tower, the contractor used diesel oil for powering the concrete mixer only. It is contained in tight jerry cans, and no oil spill was observed during the works. c) Noise Quality The common noisy equipment used was concrete mixer. Contractor applied concrete mixer for intermittent use and only for 2-3 hours a day (in average 8 machine-days) to complete concrete pouring for the foundations of each tower. There are very limited tower sites which used very loud machinery such as pile machine, rock breaker, i.e. four towers of the 275 kv Bengkayang transmission line for which Steel Mortar Composite Foundations (SMCF) system was used (approx. 4-6 days for each tower foundation) which produced very loud noise, and at 150 kv Bengkayang - Ngabang transmission line at towers 172 and 174 for which rock breaker was used for excavation. The tower sites were located away from the inhabitant area and the works were conducted during daytime so the noise impact was insignificant. d) Pollution Prevention Page 14 of 71 Fifth Semi Annual Report on Environmental Issues (30/6/2016)

22 Air Pollution See the review of item a) Water Pollution and Soil Pollution See the review of item b) Land Pollution To protect the land from pollution caused by the construction and domestic waste, in most cases, the contractors have been removing the bigger pieces of the construction and domestic waste but neglected the smaller pieces, frequently found scattered at many tower sites. The construction waste of paper cement containers, broken hemp sacks, plastic wraps and chunks of wood is found in development areas of most towers. As the majority of towers are inaccessible by car, most material is transported by motorcycle or carried by people. Sand and gravel were contained in hemp sacks and transported either by motorcycle or by human from roadside to tower sites. Cement of 50 kg each was transported in fabricated paper containers. The domestic waste associated with the construction works was also encountered at most tower construction locations and its adjacent areas. Those wastes were produced by the construction workers who throw the garbage (plastic bottles, plastic wrap) carelessly to the surrounding environment. The form work for casting concrete is made of wood and at some places as metal formwork, and is repeatedly used for concrete works at other tower locations. e) Biodiversity and Natural Resources The awareness of contractor/subcontractor/workers not to disturb the surrounding forest trees was low during construction of foundations and towers of transmission lines. Subcontractor/workers frequently cut the small to medium sized trees in surrounding forest for fixing the form work for concrete works and other uses. f) Physical Cultural Resources Until now, the finding of physical cultural resources was not reported or observed during surveillance monitoring. g) Employment opportunities The construction of foundations and erection of towers needs labours for carrying materials from roadside to tower site. The contractor recruited local people to conduct this work. It provided mutual benefit for the local people and the contractors. Especially in Seluas and Jagoibabang area the contractor for the 275 kv Bengkayang - Jagoibabang transmission line assigned local people as subcontractors for constructing the tower foundations. h) Capacity Building Workshop on capacity building had been conducted for environment, health & safety, and social issues in Bengkayang on 16 th October 2014 which was attended by Contractors of four packages of design, supply, installation, testing, and commissioning of the works as the follows: o PT.

25 4. SUMMARY OF ENVIRONMENTAL COMPLIANCE MONITORING 4.1. Summary of Inspection Activities a) Vegetation clearing. At many tower site locations and the substations the contractor conducted vegetation clearing confined to the tower and substation sites, except for the locations where there was no pathway, it has been practiced to clear the vegetation for access. Clearing vegetation of tress higher than 3 m, within right of way (ROW) have been conducted for of the entire 275 kv Bengkayang-Jagoibabang transmission line. In several places the branches and leaves of the cut trees were left scattered along the ROW. During the rainy season it was fine, but might be caught by fires during dry season. b) Soil erosion. In tower sites located in steep slope with high potential for erosion, the contractor shall provide soil erosion protection. The contractor may propose additional cost for this matter as stated in the contract document (1).After foundation construction finished, contractor conducted backfilling the holes of the tower s legs and levelized the soil in the tower area and smoothed the steep slope. This treatment will reduce the soil erosion. It can be tolerated not to apply soil erosion protection in non-critical sites such as a flat area or the site and its surrounding could naturally absorb the sedimentation. At tower sites located in steep slope with high potential for land slide or erosion some towers shall be provided with the retaining wall for land slide or soil erosion protection e.g. T.43, 91, 115, 116, 191 and 201 of 275 kv Bengkayang-Jagoibabang transmission line. The retaining wall in the entire boundary area of Bengkayang substation was completed. At Ngabang substation the retaining wall was completed at the front side and the left hand side, while the construction works on the right hand side and the rear retaining wall were in progress. c) Drainage. During the tower construction works, the construction of drainage was not practised at most tower sites, except in certain area where it is considered required e.g. very steep slope, near the flowing water area, etc. At Bengkayang substation the drainage was almost completed, leaving only small portion in the entrance area. The drainage siphon at left side of Ngabang substation has been normalized, the rain water can drain easily by undercrossing the road. d) Acid sulphate soils. No such soil was observed. No action required to be done. e) Water quality impacts. For tower foundation works, the use of water was for drilling and concrete works, and these activities generated waste water. Most of the waste water from such activities is relatively small, and although it is directly dumped to the soil it usually could be absorbed by the soil at the tower sites. The Contractor did not provide a suitable barrier to prevent such waste water to escape from the tower site. Although it rarely happened, it could be observed that such water of drilling works spilled to surrounding tower area, but only few meters from the tower site and the volume was small and it could be absorbed by the surrounding soil and create insignificant impact caused by this high soil sediment waste water. f) Air quality impacts. Contractor applied high intensive labour to conduct various works, i.e. transportation, drilling, elevating steel parts that in nature will not cause air quality impacts. g) Construction waste management. Contractor cleaned most of the construction waste, although some remaining chunk of woods, broken hemp sacks and cement paper containers remained to be removed. 1 Contract document Volume 1, Section 6: Employer s Requirements, Sub Section 6.2.3: Technical Specification item 3.12 Payments for Towers and Foundations. In this contract is stated that Additional work which may be required to secure foundations against the effects of soil erosion will be paid for at the rates to be agreed Page 18 of 71 Fifth Semi Annual Report on Environmental Issues (30/6/2016)

26 h) Domestic waste management. The waste originated mainly from the construction workers and other waste originated from local people who were hired to transport the materials from roadsides to the tower sites. In several places the domestic waste was scattered within the tower sites, temporary shelter areas and along the temporary access pathway. i) Roads and infrastructure impacts. No impact was observed in such facilities. j) Encroachment into protected forests, hunting, wood collection. No encroachment was observed. The works have started in the state forest land, but most land are bush or grass. No firewood collection from the forest was observed. No hunting activity by the workers was observed. k) Community health and safety i. Prevention of HIV/AIDS. The contractor did not provide the awareness or providing the measures in preventing the community and their workers safety concerning the sexually transmitted diseases. ii. iii. iv. Safety line and notice. The contractor generally did not provide this kind of OSH requirement in the unloading zone of materials at road sites and working areas for preventing the community entering the non-safety zone. The mobilization of materials. The transport of metal parts for the towers is of concern from the OSH point of view. Loading and unloading works in the warehouse and at the roadside carried out with the front loader machine is considered not safe enough for conducting this kind of works and may endanger the community passing by. The stringing of conductors. During stringing activities for the 275 kv Bengkayang - Jagoibabang transmission line the contractor installed scaffolding at the sites of the public utilities such as road, electrical distribution lines etc. for public safety wherever the transmission line is crossing them. l) Employment opportunities. Contractor employed local people at most tower sites for transporting the construction materials from roadside to the tower site. The local subcontractors were also employed for foundation construction of 275 kv Bengkayang - Jagoibabang transmission line and for some works of substation project activities. Local people also enjoyed indirect employment benefit from providing services such as lodging, meals, etc. for the construction employees and workers. m) Physical cultural resources. Until now no physical cultural resources were found and observed Mitigation Compliance a) Vegetation clearing. In most locations the contractor complied with the mitigation requirement except the clearing of trees along the right of way on some places, where the dry branches and foliage were left behind, scattered in some part of the right of way. The dry material will be susceptible to spread fires. b) Soil erosion. Contractor has not fully complied with the requirement. Contractor is supposed to apply soil erosion protection at the tower site which has high erosion rate such as steep slope location. At each tower location after foundation construction was finished, the contractor conducted backfilling the holes of the tower legs and levelized the soil in the tower area and smoothed the steep slope. This treatment reduced the soil erosion although it was not optimal. The vegetation cover is supposed to be planted to reduce soil erosion. Based on monitoring at many tower sites it took 3 to 6 months for the exposed soil in the tower construction area to naturally recover and revegetate by Page 19 of 71 Fifth Semi Annual Report on Environmental Issues (30/6/2016)

27 itself. c) Drainage. Most tower sites do not need the construction of a drainage system. Drainage system is needed in certain areas e.g. very steep slope, near the flowing water area. Generally contractors comply with the requirement, except for the holes of some tower legs (excavated holes or unfinished backfilling) which were inundated by rain water. d) Acid sulphate soils. Up to now this type of soil was not found. e) Water quality impacts. Most towers are surrounded by the landscape (grasses, and falling foliage) which screen the suspended solid contained in waste water generated from drilling and concrete works in the tower construction area. Although the contractor did not provide special treatment, according to observations the water quality impact seemed to comply with the requirement. f) Air quality impacts. Contractor complied with the requirement. g) Construction waste management. Contractor partly complied with the requirement but in many cases it must be improved,since the construction waste still could be found at many tower locations. h) Domestic waste management. Contractor did not fully comply with the requirement. Garbage originated from construction workers scattered in several tower locations. Almost all of the subcontractor s workers ignored this requirement. Some workers were observed to burn domestic garbage, even it was small volume but it contributed the pollution of the ambient air in the surrounding area. i) Roads and infrastructure impacts. Contractor complied with the requirements. j) Encroachment into protected forests, hunting, wood collection. Contractor complied with the requirements. k) Community health and safety. Contractor did not fully comply with the requirement, e.g. warning signs were not installed. l) Employment opportunities. Contractor complied with the requirement. The local people were hired to transport the materials from roadside to the tower locations. m) Physical cultural resources. Until present no physical cultural resources were found or observed Mitigation Effectiveness The mitigation effectiveness is low due to the following reasons: a) Lack of understanding and lack of awareness of environmental mitigation that is required to be accomplished by the contractors and their subcontractors. The environmental and safety personnel who are supposed to enforce the environmental requirement came from the contractors head office and were only appointed for short duration at the site, no fulltime officers were appointed in the site office to implement the Environmental Management Plan (EMP) 2. 2 The EMP is mentioned in the IEE (Initial Environment Examination) of 275 kv Regional Interconnection Transmission Line Mambong (Sarawak) to Bengkayang and 150 kv Transmission Lines Bengkayang to Tayan (West Kalimantan) published in 2011, in RKL (Rencana Pengelolaan Lingkungan) or Environmental Management Plan, Kegiatan Pembangunan SUTET 275 kv GI Bengkayang Perbatasan Sarawak published in 2010 and in UKL-UPL (Upaya Pengelolaan dan Pemantauan Lingkungan) of 150 kv Bengkayang-Ngabang-Tayan transmission lines Page 20 of 71 Fifth Semi Annual Report on Environmental Issues (30/6/2016)

28 The previous EMP was considered to be too stringent for several environmental mitigation measures to be implemented in scattered places and relatively very small areas. In June 2015 it had been adjusted by revising the EMP without jeopardizing the purpose of environmental impact mitigation. 5. KEY ENVIRONMENTAL ISSUES 5.1. Environmental key Issues Identified The compliance of the EMP requirement is low due to lack of awareness concerning the environmental management among the contractors, subcontractors and their workers. The root cause is that there is no personnel in charge for the site works to enforce the EMP requirements Action to be taken The four main contractors (i) PT Bukaka Teknik Utama of Package 1: 275 kv Bengkayang - Jagoibabang Transmission Lines, (ii) CG Consortium for Package 2: 275/150 kv Bengkayang substation, (iii) Consortium of KEC International Limited and Mitsubishi Corporation of Package 3: 150 kv Bengkayang Ngabang - Tayan Transmission Lines, and (iv) Siemens for Package 4: 150/20 kv Ngabang and Tayan substation, shall commit to the EMP and OSH requirements and appoint officer(s) to enforce them. Among other, they shall include: to continuously provide awareness to the main contractors personnel, subcontractors and labours concerning Environmental Management Plan requirement. to provide instruction to the labours to apply proper procedure concerning Environmental Management Plan. 6. CONCLUSION 6.1. Overall Progress of Implementation of Environmental Management Measures The contractors implementation of environmental management measures varied between good and poor as follows: In general the impact mitigation is good and fair for the following issues: Air quality impact, employment opportunities, and roads and infrastructure impacts. The issues of cleaning the construction waste is considered fair, the contractor has removed most of the construction waste but some waste remains to be removed from the sites. The issues of erosion is considered fair, the contractor has levelized most disposal and excavation soil and constructed retaining walls to protect from landslide and erosion. The implementation of environmental management measures of the following issues are considered poor: Management of protecting soil and water pollution in the oil storage and working areas by providing leakage prevention. Management of waste, especially disposed materials wrap Management of cut trees (removal of dry branches and foliage) along the right of way Page 21 of 71 Fifth Semi Annual Report on Environmental Issues (30/6/2016)

29 There are two issues which were not yet implemented, so no evaluation was conducted. These issues are in conditional matters, for which the environmental management measures shall be implemented when they are encountered during implementation: Acid sulphate soils Physical cultural resources 6.2. Problems Identified and Actions Recommended a. The four main contractors to deploy their Environmental and OSH personnel to be in charge of daily works. b. The four main contractors to assign the fulltime Environmental and OSH officer(s) to enforce the EMP and OSH requirement and always provide the awareness on EMP and OSH requirement to labours and providing instruction for the subcontractors and their labours to apply proper procedures Revised EMP The PIC has revised the EMP to adapt it to the conditions prevailing at the construction sites and it has been submitted to PLN on 30 June Page 22 of 71 Fifth Semi Annual Report on Environmental Issues (30/6/2016)

72 APPENDIX: A-5. STATUS OF THE TOWER CHANGES AND ENVIRONMENTAL REVIEW Comparing with the original schedule mentioned in IEE, there are some route changes due to relocation of the planned sites for 275/150kV Bengkayang substation and 150/20 kv Ngabang substation. The routes location are highlighted in the Map A-1 and the addition or elimination of towers as consequence of the site changes of both substations are discussed in the following paragraphs: Map A-1 Situation map of re-routing of 275 kv Bengkayang Jagoibabang and 150 kv Bengkayang Ngabang Tayan Transmission Lines e) Tower reroutes and changes of tower locations of 275 kv Bengkayang Jagoibabang Transmission Line According to the original planning, this route comprised of 199 towers (Tower No 1 in Bengkayang to Tower No 199 in Jagoibabang). For the sake of synchronizing with the route of the 150 kv Singkawang-Bengkayang transmission line, the planned 275/150kV Bengkayang substation which was originally located at the left hand side of road into direction to Jagoibabang, had been shifted to north-eastern direction at right hand side of the road, located adjacent to the 150/20 kv Bengkayang substation which is under construction and where the 150 kv Singkawang - Bengkayang Transmission Line will be terminated. Now this line comprises of 201 towers as described below: a.1) Six towers from No.1 to 6 had been eliminated, and replaced through four towers of No. A, B, C, D which had been erected to connect the 275 kv Bengkayang Substation (see Map A-1) with tower No. 7 (Coordinate X= , Y= ). For the sake of mitigating of insufficient ground clearance of Page 65 of 71 Fifth Semi Annual Report on Environmental Issues (30/6/2016)

73 conductors, an additional four intermediate/insertion towers of No. 76A, 99A, 110A, and 158A had been constructed. So in total, there are 201 towers, or two additional towers on the 275 kv Bengkayang-Jagoibabang route. Table A.1.1 Tower Changes of 275 kv Bengkayang Jagoibabang Transmission Line TOWER NUMBERS A B C D A A A A Tower inserted The 275/150kV Bengkayang substation has been shifted to North-Eastern direction at right hand side of the road, located adjacent to 150/20 kv Bengkayang substation to connect with Singkawang. The towers connecting to it were relocated (4 sites) and eliminated 2 sites. Map A-2 Tower re-routing of 275 kv Bengkayang Jagoibabang and 150 kv Bengkayang - Ngabang Transmission Lines Environmental review: The route to the new substation location at Bengkayang had less impact on forest land due to shorter distance of the Right of Way (ROW) but slightly more impact on rubber and palm oil plantation, and it also added one more crossing of the main National Road of Bengkayang - Jagoibabang and medium voltage lines. No major impact and no special environmental management measures were encountered. During the construction of towers and stringing activities the environmental standard protection measures had been applied and thereby eliminated the expected associated impact. Regarding land use of the alignment which was rubber and palm oil plantation, in general, the prediction of potential impacts to be experienced by affected households due to the permanent land acquisition for the tower bases were minor. The towers in West Kalimantan have been constructed higher than those of Page 66 of 71 Fifth Semi Annual Report on Environmental Issues (30/6/2016)

74 International standard, so the farmers may cultivate along the ROW area with the annual or perennial crops with its canopy up to 3 m in height. The impact on traffic due to main road crossing could be neglected because no traffic congestion had been encountered caused by stringing activities. Scaffolding as temporary protection made of bamboo at both sides of the road eliminated the traffic disturbance. a.2) The new 275/150 kv Bengkayang substation is being developed adjacent to the new 150/20 kv substation of Bengkayang where it will connect with the 150 kv Bengkayang - Singkawang Transmission Line, but its construction was stagnant for a long period due to financial matters. The landuse of the substation area was rubber plantation. The planned area was undulating and so it needed soil works to level the site. The higher soil level had been excavated to fill the lower level. No quarry from outside was needed for the embankment, all soil for embankment came from the same area. Environmental review: Impact on erosion and polluting the water body was minimal because there was no significant creek or river in that area. No embankment for land preparation using soil/material from other location outside, thus no hauling truck going in/out carrying soil that might cause an impact on air quality such as fugitive dust and exhaust gas. No wild animal affected, since the area was rubber plantation and bushes. Close to the substation area at approximately 100 m, there is an elementary school, but without impact on children since there is no access for them to go to the site. The substation area is fenced to protect anybody from entering the site without permission. f) Tower re-routes of 150 kv Bengkayang - Ngabang Transmission Line According to the original plan, this route would comprise of 260 towers (Tower No 1 in Bengkayang to Tower 260 in Ngabang). The total number of towers became 280 after several modifications to the number of the towers: Due to 275/150/20 kv Bengkayang Substation shifted north-eastern, it had been decided to eliminate three towers (number 1 to 3) and add of seven new towers (1A, 2A, 3A, 4A, 5A, 6A, and 7A). Tower 1A (X=332798, Y=100065); Tower 7A (X=333493, Y=98504) (see Map A-2). According to recalculation of the design regarding the conductor ground clearance, it had been decided to eliminate three towers (Tower No. 126, 157 and 158), but in addition one insert tower (Tower No. 24A) will be required. Recent consideration of land acquisition and span clearance, that Tower No 126 and 127 will still be constructed. Seven towers to be shifted due to relocation of 150/20 kv Ngabang Substation (see Map A-3.1). Eight towers will be added to connect T.1 to Tayan substation Page 67 of 71 Fifth Semi Annual Report on Environmental Issues (30/6/2016)

75 Table A.1.2. TOWER CHANGES OF 150 KV BENGKAYANG NGABANG TRANSMISSION LINE TOWER NUMBERS 1A 2A 3A 4A 5A 6A 7A A Note: Tower Changes Due to landuse problem on previously proposed Ngabang Substation, the towers connecting to it have been planned to be relocated. (The new route survey and design had been completed). As the new Ngabang substation is now closer to Tayan direction, tower No. 117 up to 133 of Tayan - Ngabang Transmission Line has been added to Bengkayang - Ngabang Transmission Line. Accordingly, the total number of towers of Bengkayang - Ngabang Transmission Line will become 280. b.1) Re-routes and addition of 7 new towers (1A, 2A, 3A, 4A, 5A, 6A, and 7A). Environmental review: Of the seven additional tower sites of 150 kv Bengkayang Ngabang Transmission Line, there are four towers which will be constructed in parallel route to the completed 150 kv Bengkayang - Singkawang Transmission Line. The later route is on the western side and the Bengkayang - Ngabang Transmission Line route is on the eastern side. The landuse of the new alignment is palm oil, rubber plant and bushes. There is no protected wild animal in the area, so the impact on flora and fauna is considered insignificant. The new route is far from the river and other water bodies, impact on sedimentation and water quality caused by new alignment can be neglected. b.2) Re-routes due to relocation of originally proposed Ngabang substation. Nine new towers will be constructed due to the relocation of the originally planned Ngabang substation site, of which seven towers will belong to the previous Bengkayang - Ngabang alignment and two towers belong to the previous Ngabang - Tayan alignment. The footprint of the proposed tower sites has been surveyed and the tower types have been designed. Page 68 of 71 Fifth Semi Annual Report on Environmental Issues (30/6/2016)

76 Map A-3.1 Tower re-routes of 150 kv Bengkayang - Ngabang Transmission Line at originally proposed Ngabang substation Note: The green mark (T.259) was planned for Ngabang substation, but now it is used as dwelling area, so it had been decided to relocate the substation to the South-East of Ngabang (see Map No. A-3.2) Tower of Tayan Ngabang shifted to become Bengkayang-Ngabang Ngabang SS Tayan Ngabang route shifted to Bengkayang- Relocated Bengkayang Ngabang Ngabang route Connected route to 116B 116A Due to (New) Ngabang substation shifted southward, towers (yellow mark) are to be relocated. Environmental review: The new alignment of the 150 kv transmission line passes through gentle area with landuse of rubber plantation and mixed garden. The area is far from the water body, so erosion and sedimentation will be insignificant. There is no protected wild animal, so the impact on flora and fauna is considered insignificant. Tower T.252 toward tower T.259 as the end tower of 150 kv Bengkayang - Ngabang route were shifted by approximately 700 m southern of original route to connect with the Ngabang Tayan Transmission Line. It will overpass the regency road and the green area along the creek in between the fast growing residential area. No significant impact is anticipated along this relocated route. g) Tower re-routing of 150 kv Ngabang Tayan Transmission Line The planned number of towers of the original plan for 150 kv Tayan Ngabang Transmission Line was 133, counting starts from Tayan substation. The total tower will become 128 due to relocation of Ngabang and Tayan substations. c.1) Towers changes to connect 150 kv Ngabang substation. The new 150/20 kv Ngabang Substation is under construction near to the previous tower No T.116 of the 150 kv Tayan - Ngabang Transmission Line (x= ; y= ). This tower was located adjacent to and on the right hand side of the main road of Pontianak Tayan - Ngabang in the village of Tebedak, Ngabang Subdistrict, Landak Regency (see Map A-3.2). Page 69 of 71 Fifth Semi Annual Report on Environmental Issues (30/6/2016)

77 Map A-3.2 Tower re-routes of 150 kv Bengkayang - Ngabang Transmission Line Environmental review: The area of the New Ngabang substation is approximately 1 ha. The topography was undulating and the level of the area about 1 to 4 m higher than the main road. There is no major settlement close to the area. To level the site, soil works had been conducted in March - April No quarry was needed for embankment and no excess soil to be moved in/out from the site, so there was no major impact on traffic caused by the land preparation. Impact on water quality during the land preparation was insignificant, since the river is about 1.5 km away. The landuse of the proposed new substation was mixed vegetation that consisted of bamboo, rubber trees and other wood trees. No protected fauna was found in that area. The Tayan - Ngabang transmission line was relocated from T.114 up to T115. In the alignment of those towers are oil palm plantations for which no significant environmental impact is expected. c.2) Tower additions to connect with 150 kv Tayan substation In the original tower schedule, the first tower (T.01) of Tayan is not adjacent to the existing Tayan substation, because the originally planned Tayan substation was relocated about 2.5 km southward due to land acquisition and other consideration of the Siantan-Tayan transmission line route. The Tayan- Ngabang transmission line needs nine additional towers (1A, 1B, 1C, 1C1 1D, 1D1, 1E, 1F and 1G). Environmental review: The direct route will cross the national road that connects Pontianak with several regencies in eastern part of West Kalimantan and in the future to southern part of West Kalimantan after the Kapuas (1.5 km) bridge will be completed. The crossing point of the transmission lines with that important road will be in the area which is very close to the cross junction road connecting Tayan Sosok. That area is a new high value commercial area where several buildings (some of them with two storey floors) have been built along this road, leaving relatively narrow corridors in between that could be used as the route for the transmission line.
