7 1. INTRODUCTION In accordance with the Project Administration Manual of the loan agreements with ADB and AFD of July 2013 of West Kalimantan Power Grid Strengthening Project of Item D. Consultant's Terms of Reference sub item 1. Scope of Services for Project Implementation Consultants (Firm) paragraph 62, that the consultant shall prepare the Quarterly progress reports to be submitted to PLN. 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: Package 1: 275 kv Transmission Line between Bengkayang substation and the border with Sarawak, East Malaysia (80.26 km). Package 2: 275/150 kv Substation at Bengkayang. Package 3: 150 kv Transmission Lines from Bengkayang substation to the new Ngabang substation (93.34 km), and from there to the existing Tayan substation (46.64 km). 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. The report on occupational health and safety (OHS) is presented separately. 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 5. According to the original plan of the 275 kv Bengkayang Jagoibabang Transmission Line (Sarawak border) that comprises of 199 towers (extended from Tower No 1 in Bengkayang to Tower No. 199 in Jagoibabang). Six towers from No. 1 to 6 had been eliminated; instead of new 4 towers had been added. Besides, there are more addition of 4 inserted towers resulted 201 towers in total. The original plan of 150 kv Bengkayang - Ngabang and 150 kv Tayan - Ngabang transmission lines comprise of 393 towers in total (260 towers and 133 towers respectively). There are several modifications have been made to the total number of towers of the Bengkayang Ngabang and Tayan - Ngabang transmission lines. The total towers finally increase to 408 towers (there are 280 towers and 128 towers respectively). The detail is as follows: Bengkayang Ngabang route a) The shifting of 275/150 kv Bengkayang Substation position to north-eastern direction resulted in the elimination of 3 towers and addition of 7 new towers. b) 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: Page 1 of 76

8 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 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. c) There are two towers (T.157 and T.159) to be eliminated due to span condition and one additionally inserted tower (T.24A). 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. In June 2016 PLN had acquired the land for eight locations. Two additional towers as insert tower at T.04A and 73/1. Thereby the Bengkayang Ngabang - Tayan transmission lines will comprise of 408 towers, i.e. 280 towers for the Bengkayang Ngabang section and 128 towers for the Tayan - Ngabang section. Detailed information concerning the environmental review on relocation of the substations and towers is elaborated in detail in Appendix 5. Map 1.

17 4. ENVIRONMENTAL MITIGATIONS AND LAND ACQUISITION IMPLEMENTED 4.1. Environmental Mitigations a) Air Quality: Air quality deterioration could be caused by exhaust gas of construction machines (truck, car, motor cycle), operation of concrete mixer, drilling/pilling machineries and heavy vehicles for land preparation (these are mostly utilized for substation works; rarely for tower works). Concrete mixer Concreate mixer equipped with small diesel engines used intermittently about 8 hours a day for pouring concrete at each tower pad. This machine is considered producing few emission then assumed no air pollution occurred. In addition, there are no people affected since the locations are away from villages. Drilling and excavation Man power are mostly used in excavation works. There are two method in soil excavation works depends on the soil condition. At a low bearing soil capacity (soft soil), holes were excavated by a drilling machine. While at a better soil condition (hard soil), either the foundation holes dig manualy or drilled by pile driver machine. The use of drilling machine assumed to generate more air pollution but not significant. Erection of towers No machinery used, so there is no air pollution. Transportation of material. Construction material was transported in two ways from store house. First, material transported directly to the site if the location can be accessed by truck (i.e. substation or tower sites that located just at roadside). Second, if the tower site is far from main road or cannot be accessed by truck, then the material carried to the roadside that closest point from the tower site. From this point the material transported manualy by labour or motorcycle to the tower sites. No significant air pollution assumed from this activity. Land preparation of the substations. The land preparation works is to clear and levelling the undulated ground of the Ngabang substation. But this works is not for the Tayan substation since the land has been ready for construction. The higher ground level in the site was cut to fill lower ground using bulldozer and backhoe. No outside quarry needed to produce soil embankment. Further, there is no transporting soil from outside, then generated dust can be minimized. b) Water Quality Water quality deterioration may be caused by soil works, concrete works, spilled diesel/oil. Soil works may generate turbid water and sedimentation in water body. Concrete works usually produce alkaline water and turbid water due to the cement deposit. In addition, spilled diesel/oil could be occured due to negligence, misconduct and or accident, further it may pollute into soil and water. Water pollution may be also from acid soil encountered during the excavation works. It may produce acid water that pollute the water body. Page 11 of 76

18 So far there was no water pollution indicated significantly at the sites; So there is no need specific measures applied. There are several sources of impact predicted to cause water pollution, as follows: Drillings and excavations. If soft soil indicated in a tower pad area, foundation holes shall be dig by manual drill equipment to locate concrete piles. But some drilling machine may be limited used at some specific locations. Where the soil was considered harder (better condition), no drilling method was applied. Instead of this, manual excavation was conducted in all tower pads. Both of drillings and excavations generated heap of soil and bare surface. Once the concreating finished, the soils were backfilled to the foundation holes. Further, the bare land and soil heaps may be sensitive to be washed away by storm water when it rains. The strom water that containing much soil sediment will be drained and pollute into water body surrounding areas. The soil heaps will be backfilled to the fondoution holes. Fortunately, most towers are surrounded by natural grass, bushes and litter of foliage. These will screen naturaly the soil sediment carried by storm water. So far, these activities generated insignificant soil erosion. Land preparation. Substations of Ngabang and Tayan The land preparation of Ngabang and Tayan substations cover an area of about 1 ha each. The clearing and levelling the ground surface, done prior to civil works begun. Acces roads in the substations are paved by asphalt, and ground surface at the switch yards covered by gravel to prevent from soil erosion. Also, surround retaining walls were constructed at substations to protect soil from erosion and land sliding. Open ditches were constructed inside of the plant area and between main/access road and the substations to control run-off water from in-beetwen area that may cause a local flooding. Tower Pads of Bengkayang Ngabang - Tayan Transmission Lines Final contour of tower pads were carried out following the each tower designs. Levelling the ground of the tower pads was done to reduce run off. Decreassing the slope is necessary to prevent soil erosion. In particular, the tower pads locate at steep slope need to develop retaining wall to protect tower pads from land slide. Concrete works. The concreate works wastes such as spilled cement liquid and alkaline/turbid waters from equipment cleaning were assumed a little amount that generated insignificantly impacts to the soil and water surrounding project sites. Oil uses. The contractor used diesel oil for powering the concrete mixer only. It is contained in jerry cans securely, and no signiificant oil spill was indicated during the works. c) Noise Pollution Page 12 of 76

19 The noise sources are mainly from concrete mixer, drilling and excavator or bulldozer machines. But the most equipment used during construction works was concrete mixer. While, the drilling machine, excavator and bulldozer are temporarily used in sub station works. Drilling pile machine and rock breaker also used but in limited time under specific circumstances at some tower sites. The rock breaker machine Steel Mortar Composite Foundations (SMCF) was previously used approximately 4-6 days for four towers of the 275 kv Bengkayang transmission lines and at 150 kv Bengkayang - Ngabang transmission line at towers no. 172 and 174. But, the noise impact was considered minimum since the tower sites were located away from inhabitant area, and the works were conducted during day time. d) Pollution Prevention Air Pollution See the review of item a) Water Pollution and Soil Pollution See the review of item b) Land Pollution Sources of this impact are the construction and domestic wastes. In most cases, the contractor have removed the large size of the construction and domestic wastes but some smaller pieces found scattered at many tower sites. The construction wastes of paper cement containers, broken hemp sacks, plastic wraps and chunks of wood is found in development areas of most towers. The domestic wastes produced by the construction workers who throw the garbage (plastic bottles, plastic wrap) carelessly to the surrounding environment. The woods for pouring concreate were reused in further concreate works. e) Biodiversity and Natural Resources The project passes some forest lands, that not categorized into the conservation/protected forest. It means, there are no protected or endangered plants affected by project. The most vegetations affected by project are plantation crops such as rubber, palm oil, seasonal crops and bushes. There are several public forest lands (but the lands owned by government) affected by project but they are mostly not well maintained which grown by shrubs and bushes. The workers were allowed to use woods resulting from clearing for construction purposes in limited amount. But entering into the forest out of the ROW cutting area for personal purposes is prohibited. f) Physical Cultural Resources Until now, the cultural heritage resources was not indicated during surveillance monitoring. g) Employment opportunities Local subcontractors with local labours have been hired to do project works such as substations works, tower works, tree cutting and stringing. These works have provided benefits for local peoples. h) Capacity Building Page 13 of 76

20 There is no any capacity building taken place during this period. Previously, a workshop on capacity building of environment, health & safety, and social issues in Bengkayang was commenced on 16 th October 2014 which attended by : The contractors of four packages works as follows: o PT.

SUMMARY OF ENVIRONMENTAL COMPLIANCE MONITORING The Environmental Management Plan (EMP) has been updated on June 2015 to consider the national and local standards. This updated EMP is enclosed on the Appendix A-6 of the report. The following environmental management reviews, therefore, refer to the updated EMP Summary of Inspection Activities a) Vegetation clearing Vegetation clearing was done by local sub contractors after the compensation completed. Clearences area followed the designed drawings of tower sites and routes of ROW of Bekayang Ngabang Tayan Transmission Lines. All tree cutting and clearances were used hand tools (including chain saw) without any heavy machines used as well as no burning applied. Tree cutting in particular addressed to the trees that higher than 3 m. All dry vegetation cut were left at the sites along the ROW lines. There were no any woods collected from the clearing sites for personal uses except for the construction purposes, such as temporary retaining wall, scaffolding works, temporary hut etc. Making fire in the clearing sites is strictly prohibited since the dried cut easily burned. But limited fires for cooking may be made by workers. b) Soil erosion Soil erosion might be generated from foundation works at substations and towers sites. The foundation holes resulted from excavation works were backfilled by the dig soil during finalization of the works. To control soil erosion, area of the sites of substations and towers have been levelled following the designs. In particular, the substation sites have been facilitated by drainages to drain off the storm water and reducing soil erosion. However, at the tower sites, the uses of drainange depend on the need of the sites. The uses of retaining walls, especially at steep sites is necessary to retain soil erosion and land sliding. c) Drainage Most of tower sites were not facilitated by drainages, except in certain area where it is considered required. But drainages have been constructed at the substations sites to drain off the storm water. d) Acid sulphate soils. No such soil was observed. No action required to be done. Page 16 of 76

23 e) Water quality impacts Source of impacts are run-off water and oil/diesel spill. The run-off water has been controlled by drainages construction at the substations sites. But there is no drainage made at tower sites. The spill diesel from machines uses are considered minimal and no significant impact on water quality. During tower foundation works, the water for drilling and concrete works may generate waste water. But this is considered small amount and will be absorbed by soil surrounding tower sites. f) Air quality impacts The machine are very limited used in the construction process. Thus air quality are not significantly affected. g) Construction waste management The construction wastes were cleaned by contractors. But some still remained there such as small portion chunk of woods, broken hemp sacks and cement paper containers. h) Domestic waste management The garbages (plastic bottles, plastic wrap) produced by the construction workers thrown carelessly to the surrounding environment. The wastes were scattered within the tower sites, surrounding their huts/temporary shelters and along the temporary access/footpath. i) Roads and infrastructure impacts No impact was observed in such facilities. j) Encroachment into protected forests, hunting, wood collection No encroachment was observed. Some transmission lines passed the public state forest lands, but most lands are grown by bushes or grasses. No firewood collection from the forest was observed. Also, no hunting activity by the workers indicated. k) Community health and safety Prevention of HIV/AIDS. o The contractor have campaigned the awareness of the sexually transmitted diseases to the their workers. Safety line and notice. o Safety lines and notices were not apllied by the contractor to prevent the people entering unsafe zones during unloading the steel materials at roadsides and or storehouse area. The mobilization of materials. o The use of front loader equipment to load and unload the materials at both of Page 17 of 76

24 roadsides and warehouse is considered unsafe for people passing by. Neen more sufficient safety notices and lines applied. The stringing of conductors. o Scaffoldings are used during stringing activities for the 150 kv Bengkayang Ngabang - Tayan transmission lines which crossing public utilities. The affected public utilities such as road, electric lines etc were protected by scaffoldings made of bamboo or woods to prevent the community affected by the stringing process. l) Employment opportunities The contractor hired local subcontractors that also employed local people to execute the construction works such as foundation, tower erection, tree cutting and stringing etc. Surrounding people also had benefit by selling meals or foods or other daily needs to the workers. m) Physical cultural resources. Until now no physical cultural resources were found and observed Mitigation Compliance a) Vegetation clearing In general, the clearing process can be handled adequately by the contractor. There are no serious impacts that considered to endanger the environment. Also, there are no protected plants affected by the cutting. But, it must be concerned that the dried cut likes woods, branches, leaves remained at the location must be protected from fire. b) Soil erosion Measures in soil protection have been made by the contractor to reduce soil erosion such as paving the substasion roads, finalizing the ground surface referring to the designs, decreasing the slope of tower pads, backfilling the foundation holes, establishing retaining walls surrounding the substations, gravel covering on the swith yards area. c) Drainage Most tower sites do not need to construct a rigid drainage system. Open drain may be necessary for some towers, especially located at concave sites to drain off storm water. All substations have been facilitated by open drains to control storm water. d) Acid sulphate soils Up to now, this type of soil was not found. e) Water quality impacts There is no special measures provided to control water quality. The construction Page 18 of 76

25 works did not significantly generate pollution to affect the surrounding water body. f) Air quality impacts Contractor complied with the requirement. g) Construction waste management In general the contractor clean the construction wastes after the works completed. But some construction wastes likes woods, cement sacs, plastic bags are still remained. The cleaning works need to be improved. h) Domestic waste management Similarly with the point (g) above, the workers did not adequately manage their wastes after finishing the construction. The wastes such as plastic bags, papers are scattered at some towers sites. 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 During the stringing works, contractor installed scaffolding that passing at the public sites to protect communities from dangerous activities. Unfortunately, there are no warning signs included. 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 Up to now, there are no physical cultural resources indicated Mitigation Effectiveness Some notes in the mitigation review are as follows: In general environmental mitigation measures have been fairly done; but some are still insufficient applied sush as in managing of construction and domestic wastes; Eventhough the environment/osh officer has been hired by KEC but the final inspection of wastes cleaning after the construction finished was not adequately controled; Lack of monthly environmental monitoring report from the contractor submitted to the PLN causing insufficient control in environmental mitigation compliance. Page 19 of 76

26 6. KEY ENVIRONMENTAL ISSUES 6.1. Environmental key Issues Identified To increase in imposing of the EMP by the contractor to their subcontractor and their workers Action to be taken The contractor (KEC Int. consorcium) shall commit with the EMP and OSH requirements to enforce the EMP to both of the contractor employees and the sub contractors as well as their workers. The tasks must be concerned as follows: The environmental mitigation measures should be imposed following the EMP to whole involved personnels; To control adequately the apllied environmental mitigation measures during the construction works; To provide monthly environmental monitoring reports that submitted to the PLN and copied to the consultant; 7. CONCLUSION 7.1. Overall Progress of Implementation of Environmental Management Measures In general, the environmental management measures are fairly applied. However, some mitigation measures that insufficient applied are as follows: The wastes of construction and trashes cleaning were not adequately carried out after the works finished. The unused woodens, paper cement bags, plastic bags, plastic food wraps scattered surrounding the sites; The soil heaps located at outsite of sub station area (Tayan) was not managed well. The storm water washed the soils away and may generate polluted water coming into the surrounding water body; Fire for cooking made by workers around their hut must be concerned well, since it be able to burn easily the dry leaves and woods; 7.2. Problems Identified and Actions Recommended a. The main contractors should assign the Environmental and OSH personnel to be more active in controlling environmental works; b. The main contractor shall adequately imposing the EMP and OSH requirements to the sub contractors and their employees c. The main contractors shall establish routine monthly environmental monitoring report to be submitted to the PLN and the consultant Updated EMP The EMP has been updated to adapt the local and national regulations aswell as the conditions prevailing at the construction sites. This updated EMP has been submitted to PLN on 30 June The updated EMP is shown in Appendix A-6. Page 20 of 76

70 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 a) 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 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 conductors, there are an additional four intermediate/insertion towers of No. 76A, Page 64 of 76

71 99A, 110A, and 158A had been constructed. So in total, there will be 201 towers, or more 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 electricity 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. Page 65 of 76 Regarding land use of the alignment which was rubber and palm oil plantation, in general, the 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 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.

72 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 very slow 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. The 275/150 kv Bengkayang substation has been operated for receiving electric energy from Mambong substation in Sarawak. The energy is transmitted using 150 kv Ngabang bay (as temporary service) to Singkawang transmission lines. This temporary solution had to be taken because the 150 kv Bengkayang- Ngabang transmission line is not completed yet and at the time being the construction works for the 150 kv Bengkayang switchyard for the 150 kv Bengkayang-Singkawang transmission line is still ongoing. 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 to 300 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 have been fenced to prevent anybody from entering the site without permission. b) 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 tower will become 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 seven new towers (1A, 2A, 3A, 4A, 5A, 6A, and 7A), see Map A-2. According to recalculation of the design regarding the conductor ground clearance, it had been decided to eliminate two towers (Tower No. 157 and 158), but in addition one insert tower (Tower No. 24A) will be required. Seven towers to be shifted due to relocation of 150/20 kv Ngabang Substation (see Map A-3.1). It is planned that nine towers will be added to connect T.1 to Tayan substation. Page 66 of 76

73 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 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 new 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 latter 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, 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, out 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 67 of 76

74 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 Connected Ngabang route route to 116B 116A Page 68 of 76 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 had been decided to be shifted by approximately 700 m southern of original route to connect with the tower of the Ngabang Tayan Transmission Line. It will overpass the regency road and the green area along the creek in between the highly growing residential area. No significant impact is anticipated along this relocated route. c) 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 number of towers will become 128 due to relocation of Ngabang and Tayan substations. c.1) Tower 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 with 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).

75 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 at 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 will be relocated from T.114 up to T115. In the alignment of those towers are palm oil 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 previous 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 needed 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 length) bridge has been 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 those road, leaving relatively very narrow corridors that could be used as the route for the transmission line.
