Chapter 3 Environmental Mitigation

The status and outcomes of the environmental mitigation conducted for Packages 3, 5, 6 and 7 in

the period of January - June 2018 is described in the following sub-chapters of this report.

The environmental mitigation measures defined in Table 9.1 Environmental Management Plan of

the Project’s Initial Environmental Examination or IEE (2011) should be conducted for construction phase under Package 3 (Bengkayang – Ngabang – Tayan power transmission lines). The mitigation measures implemented by the Project for Package 3 is reported in Sub-chapter 3.1

The Project’s IEE (2016) applies for Packages 5, 6 and 7. The construction activity currently underway is the 150 kV Sanggau and Sekadau substations and extension of Tayan substation for

Package 5, 150 kV Tayan – Sanggau power transmission lines for Package 6, and Sanggau – Sekadau power transmission line for Package 7. Therefore, the environmental mitigation defined in

Construction Phase section of Table 28 Environmental Management Plan of the IEE should be

conducted. The mitigation measures implemented by the Project for Packages 5 to 7 are reported

in Sub-chapters 3.2 to 3.4.


3.1 Package 3: 150 kV Bengkayang – Ngabang – Tayan Power Transmission Lines (Construction)

The Bengkayang – Ngabang – Tayan transmission lines were in the construction phase with stringing of the power lines as the primary activity in the Semester 1/2018 period. The progress of the construction phase is reported 100% as of the end of June 2018. Table 2 describes the mitigation

measures implemented by the Project for this construction activity, including its compliance level against the mitigation requirements defined in the

IEE (2011).

Table 2 Environmental Mitigation Status of Package 3

No Potential Impacts / Mitigation Requirements per IEE

(2011) Mitigation Implemented Compliance Status / Remarks

1. Vegetation Clearing (HVTL alignment)

The RoW is sited so as to avoid high value plantation trees and mature secondary forest trees as practical

as possible.

The alignment of transmission line routes has considered avoiding plantation and forestry areas as

indicated in tower schedule. However, several towers

pass through the forest area as this situation cannot

be avoided. For this reason, PLN has secured the

Head of Capital Investment Coordinating Board

Decree No. 6/1/IPPKH/PMDH/2017 (dated on

January 16, 2017) on Forestry Permits (Izin Pinjam

Pakai Kawasan Hutan or IPPKH) to enable

construction and operation of parts of the

transmission line crossing the forest area. The copy of

this permit is included in Appendix 2.a.

Based on this IPPKH permit, PLN will conduct reclamation and re-vegetation in 2018 – 2021 for forest areas that have been disturbed by the

construction of the transmission line.

The mitigation implemented with this

regard is compliant with its

requirement.

Vegetation removal will only be allowed within the designated width of the RoW and the minimum area

required for other infrastructure and activities.

Vegetation cutting within the RoW will be undertaken to achieve the required clearances.

Vegetation cutting within the RoW was conducted to

achieve the required clearance in accordance with the

requirements of the MEMR Regulation No. 18/2015.



requirement.

Tree removal and trimming will only be undertaken by hand tools, including chain saws.

No tree removal was undertaken during the Semester

1/2018 period.

Not applicable.

The use of herbicides will be strictly prohibited. The prohibition on the use of herbicides has been stated in the monthly MoM on February 15, 2018, although

vegetation removal is not conducted during the reporting



requirement.




period, as shown of Appendix 2.a.

Local people will be allowed access to cleared vegetation for the collection of building materials and

firewood.

No vegetation clearing was conducted during the

reporting period. Therefore, this mitigation requirement

not conducted.

Not applicable.

Burning of cleared vegetation will not be allowed; instead this material will be used to protect the soil

from erosion, particularly in steeper slope areas, until

more permanent soil protection measures are in

place.

No vegetation clearing conducted during the reporting

period. However, the contractor has provided the

warning sign that the burning of cleared vegetation is

prohibited during this project (as shown in Appendix

2.a)



requirement.

2. Soil Erosion (HVTL alignments)

Soil erosion control measures have been incorporated into the engineering design, including

the use of tower legs with adjustable height which

allow the tower to conform to the slope of the site,

thereby reducing land cutting and erosion.

In addition, mitigations designed in accordance with relevant guidelines and good construction practices,

adapted to suit the requirements at each site, will

include:

Minimizing the extent and duration of land

disturbance on steep slopes;

Using sandbags, banks or channels to divert

water flows from upslope around the disturbed

area;

Using vegetation cut during the establishment of

the RoW to protect the disturbed ground on a

temporary basis; and

The soil erosion control measures will be

regularly inspected and maintained during

construction and until the area is stabilized and

re-vegetated.

This mitigation requirement is not applicable for the

reporting period as the stringing works of the power

transmission lines do not cause soil disturbance.

Photo showing the stringing activity is included in

Appendix 2.b.

Not applicable.

3. Drainage (Substation)

The mitigation requirements for drainage are intended for the operation of transmission lines. Therefore, it is not

applicable for the operation of substation reported in this table.

Not applicable

4. Acid Sulphate Soils (HVTL alignments, Substations)




No areas of potentially acid forming soil have been

identified in the Project alignment. However, if such

conditions are encountered, the following mitigations

will apply:

If possible, excavation (such as for tower bases) should be avoided in areas with permanently

saturated soil, peat and swamp (if such are

encountered).

If it is not possible to avoid these areas, then care should be taken to minimize the exposure to air and

drying of saturated soil. The purpose is to minimize

oxidation, for instance: minimize the time in which the

excavation is left open; If possible, soil that is

saturated at the time of excavation should be

returned to the excavation on completion so that it

remains saturated thus preventing oxidation;

excavated soil which is saturated at the time of

excavation should be mixed with lime to neutralize

acidity, especially in the surface layers; and excess

oil should be mixed with lime and buried.

The construction of tower bases and sub-stations has been designed to avoid areas with permanently

saturated soil, peat and swamp, and hence

minimizing the potential for encountering acid

sulphate soil conditions.

Nevertheless, the Project reportedly does not have formal procedures to anticipate acid sulphate soil

conditions or have communicated this precaution to

the Contractors.


regard is not compliant with its

requirement.

5. Water Quality Impacts (HVTL alignments, substation)

To protect against impacts on water quality arising

from the spillage of oil, fuel and other hazardous

materials, good international practices will be

adopted, including:

Fuel, oil and hazardous materials will be stored in designated areas with temporary impermeable

bunds in accordance with international standards

and at distance of at least 100 m from any water

course.

Refueling of machinery, equipment and vehicles will be undertaken at distance of at least 100 m

from any water course.

Any major work including oil changing and engine maintenance with the potential for oil to be spilled

will be done in designated areas at distance of at

least 100 m from any water course with

Fuel, oil and hazardous materials and wastes were stored in the contractor's warehouse without proper

segregation.

Refueling of vehicles was undertaken at the gas station. However, refueling of the stringing machine

was carried out at the construction site at adequate

distance from water courses.


was conducted at the workshop.

Relevant evident related to the above descriptions is

shown in Appendix 2.c.

The mitigation implemented with this regard is partially compliant with its

requirements.




containment to prevent any oil spills

Waste oil shall be collected and taken away for recycling.

Oil contaminated material shall be disposed of at designated waste disposal facilities.

Herbicides will not be used in the Project. The prohibition on the use of herbicides has been stated in the monthly MoM on February 15, 2018, although

vegetation removal is not conducted during the reporting

period, as shown earlier in Appendix 2.a.



requirement.

6. Air Quality Impact

Substation construction sites and access roads should be sprayed with water as necessary to

suppress dust.

Accumulated soil and debris should be cleaned from the adjacent tarmac roads as required.

Trucks should pass through a water pit when leaving the site, and excessively muddy trucks

should be washed prior to departure from site.

Truckloads should be covered, with the exception of on-site or local trips.

Cut and fill should be balanced to the maximum extent possible at each site in order to minimize

the need for fill and for spoil disposal.

Soil and temporary spoil piles should be covered or sprayed if generating dust. Piles that are not going to

be used in the short term should be allowed to

develop vegetation cover.

The main activity conducted for Package 3 is stringing of

the transmission line involving the use of stringing

machine, light vehicles, and the cable itself. This activity

does not cause major dust generation, soil and debris,

cut and fill, muddy trucks, and spoil piles. Therefore, the

mitigation requirements as defined herein are not

relevant during the reporting period.

Not applicable.

7. Construction Waste Management (HVTL alignments, Substations)

Solid wastes generated from construction activities

should not be haphazardly left around construction

sites:

Construction waste will be contained in a designated area on each site (tower site, substation or

substation access road).

Wastes will be routinely collected and disposed of at

The contractor has provided trash bags placed at

designed areas within the construction site. Trash

bags that have been full of construction garbage on a

regular basis have been disposed to Tebedak final

disposal owned by Sanggau District. Supporting

documents related to this mitigation are shown in

Appendix 2.d.



requirements.




licensed waste disposal facilities.

8. Domestic Waste Management (Worker Camps)

Temporary worker camps will be required to be provided with appropriate sanitation facilities,

including water supply, washing facilities,

temporary toilets, and waste containers.

Based on ADB mission in December 2017 related to the

workers camp conditions that are still not feasible, on

March 2018 the contractor has increased the number of

worker camp into 2 houses rented from the local people

and improved the sanitation facilities, including water

supply, washing facilities, temporary toilets, and waste

containers.

Supporting documents related to this mitigation are

shown in Appendix 2.e.



requirements.

Toilets should either by of a pit type that are at least 20 m from any water body, or porta-potty

type. If the latter, toilets should be emptied on a

regular or as needed basis, and the effluent

disposed of at an approved waste disposal facility.

As stated earlier the contractor has improved the

sanitation facilities of worker camp as shown in

Appendix 2.e.

Worker camp sanitation facilities should be developed in consultation with relevant local

authorities and has all required local, province and

national approvals.

The contractor does not develop the sanitation facilities.

Therefore this mitigation requirement is not applicable.

All worker camps should be decommissioned at the moment it is no longer required and restored to

their natural condition.

Since the temporary worker camp is rented local

people’s houses, so there is no requirement to conduct the mentioned restoration. Therefore, this

mitigation requirement is not applicable.

9. Roads and Infrastructure (Roads adjacent to HVTL alignments, substations)

A survey will be done at the commencement of the Project to determine the initial condition of such

assets and infrastructure.

No survey was undertaken as the construction activity

during the reporting period was primarily stringing

works. Therefore, this mitigation requirement is not

applicable.

Not applicable.

Any damaged infrastructure will be repaired to at least the same standard and condition on

completion of the Project.

Based on observation, at this stringing phase there is

no significant road damage occurred (as shown in

Appendix 2.f)

regard are compliant with its

requirements.

11. Occupational Health and Safety (HVTL alignments, substations)

Prior to the commencement of civil works a

construction phase Occupational Health and Safety

Plan (OHSP) will be developed. The OHSP should:

identify and minimize, so far as reasonably practicable, the causes of potential hazards to

workers, including communicable diseases such as

HIV/AIDs and vector borne diseases;

provide preventive and protective measures, including modification, substitution, or elimination

of hazardous conditions, with particular attention to

live power lines, working at height, EMFs, and

exposure to chemicals;

provide measures for the management and appropriate disposal of hazardous wastes to

ensure protection of the workforce and the

prevention and control of releases and accidents;

provide for the provision of appropriate personal protective equipment (PPE) to minimize risks;

provide training for workers, and establish appropriate incentives to use and comply with

health and safety procedures and utilize PPE;

include procedures for documenting and reporting occupational accidents, diseases, and incidents;

and

Include emergency prevention, preparedness, and response arrangements in place.

KEC International Limited as the contractor of the power transmission lines of Package 3 has

developed an environment, health and safety (EHS)

plan. The plan is signed but not scheduled yet, and

therefore its validity is unknown as shown in Appendix 2.h.

The EHS plan provides guidance and procedures primarily for safety aspects and few for environment

aspects which area considered adequate for

implementation by the Project, including:

EHS Policy

Organization structure

Project safety committee

Organization and responsibility

Personnel protective equipment, including rules

and training for fall protection; belt inspection; and

lanyard inspection.

First aid procedures

Safety rules for store area, maintenance personal,

transmission line construction

rules and use APD properly;

submitting monthly reports including documenting

and reporting occupational accidents, diseases,

and incidents; and

Establishing emergency response procedures

including provision of first-aid kids, fire

extinguishers, and emergency call lists at

construction sites.

Relevant evident of these mitigation measures are

included in Appendix 2.h.

However, the EHS plan does not provide procedures for risk identification and minimization of

potential hazards to worker including corresponding

preventive and protective measures.

12. Community Health and Safety (HVTL alignments, substations)

Prior to the commencement of civil works, a

construction phase Community Health and Safety

Plan (CHSP) will be developed. The CHSP should

include:

procedures to identify and minimize, so far as reasonably practicable, the causes of potential

Project related hazards to local communities,

including communicable diseases such as

HIV/AIDs and vector borne diseases;

specific emergency response procedures;

emergency contacts and communication systems/ protocols;

procedures for interaction with local and regional emergency and health authorities;

emergency equipment and facilities (e.g. first aid stations, fire extinguishers/hoses, sprinkler

systems);

protocols for fire truck, ambulance and other emergency vehicle services;

evacuation routes and meeting points; and drills.

KEC International Limited (KEC) does not have a specific CHSP for the construction of power

transmission lines of Package 3, although some

elements required for it are included in the existing

EHS plan described in the OHS plan described

earlier, as follow:

establishing and providing emergency response

procedures and emergency response equipment

and facilities including provision of first-aid kids,

fire extinguishers, and emergency call lists at

construction sites.

providing emergency contact and communication

system/procedures.

providing the evacuation routes, meeting point

and drills.

local and regional emergency and health authorities;

13. Employment Opportunities (HVTL alignments, substations)

The requirements defined to mitigate impacts arising from the employment opportunities are defined and

reported in the social monitoring report submitted separately from this report.

Not applicable.

14. Physical Cultural Resources (HVTL alignments, Substations)

A chance find procedure will be in place:

If physical cultural resources are encountered during the construction phase, all works at the find

site should be immediately halted.

The find should be assessed by a competent expert, and procedures to avoid, minimize or

mitigate impacts to the physical cultural resources

should be developed by the expert in cooperation

with the relevant local heritage authority,

proportionate to the value of the resource in

question and the nature and scale of the Project’s potential adverse impacts on it.

Work should not begin until the procedures to avoid, minimize or mitigate impacts to the physical

cultural resources have been implemented.

When avoidance is not feasible, no alternatives to removal exist, and the Project benefits outweigh

the anticipated cultural heritage loss from removal,

the physical cultural resource should be removed

and preserved according to the best available

technique.

Any removal should be conducted in accordance with relevant provisions of national and/or local

laws.

Records should be maintained of all finds, including chain of custody instructions for movable

finds.

All Project workers and staff should be made aware of the chance find procedure.

There have been no reports conveyed or reported by

the contractor related to physical cultural resources

within the construction site of the transmission line

within this reporting period. However, the chance find

procedure has not been developed by the Project.

The Project is not compliant with the

mitigation requirement as the chance

find procedure has not been

developed.

a temporary fence construction. In order to prevent

erosion, in the early construction phase, compaction

has been carried out in the embankment area at the

location of the Sanggau substation as shown in

Appendix 3.b



Construction of slope protection (e.g. retaining wall, gabions etc). And planting of vegetation strips

shrubs and grasses across contours of exposed

slopes.

As stated earlier, there is no construction of slope

protection yet; therefore this mitigation is not applicable

during S1/2018.

Not Applicable




Under the outdoor equipment there will be deployed gravel over the land; the unused open

area will be covered with grass and small plants.

There will be very limited erosion problem.

As stated earlier, therefore this mitigation is not

applicable during S1/2018.

Not Applicable

The soil erosion control measures will be regularly inspected and maintained during construction and

until the area is stabilized or re-vegetated.

Soil erosion control have been carried out and

monitored regularly during this construction until

completion period.

The implementation of soil erosion control measure has

been reported in the HSE monthly report by the

contractor.

The documentation related to this mitigation is shown in Appendix 3.b

Site drainage plans will be developed in accordance

with good drainage practices management for each

substation, including constructing above flood levels

and ensuring drainage around the site is provided for

high storm flows.

The final drainage design drawing have not been

submitted by the contractor, therefore the mitigation

steps by constructed drainage above the flood level and

ensured drainage around the site provided for high

storm flow have not been implemented yet.

The mitigation measures implemented by the Project are not compliant with

its mitigation requirement.

4. Water Quality Impacts (HVTL alignments, substations)

Mitigation measures to protect water quality from

erosion are the same as “Vegetation Clearing” and “Soil Erosion, above. To protect against impacts on water quality arising

from spillage of oil, fuel and other hazardous

materials, good international practices will be

adopted, including:


bunds in accordance with international standards

and at distance of at least 100 m from any water

course.



Any major work including oil changing and engine

Fuel, oil and hazardous materials and wastes were stored in the contractor's warehouse without proper

segregation.

According to PLN DIVK3L letter No.0199/KLH.01.02/KDIVK3L/2017 (dated 15 May

2017) on Repairing and Organizing Material

therefore this mitigation are not applicable.

Not Applicable

Accumulated soil and debris should be cleaned from adjacent asphalt roads in the entrance of

substation.

Accumulated soil and debris has been cleaned from

adjacent asphalt roads in the entrance of substation as

shown in Appendix 3.d



Truckloads with dusty soil should be covered, with the exception of on-site or local trips.

Trucks operating in this period transported vegetation

cleared waste to the final disposal which located near

the substation's location (local trips). Therefore this

mitigation measures are not applicable in this period.

Not Applicable

Cut and fill should be balanced to the maximum extent possible at each site in order to minimize the

need for fill and spoil disposal.

The cut and fill volume corresponds to Bill of Quantity

(BoQ) contract and drawing design. The current

activities on substation are only site clearing work and

a temporary fence construction. There is no cut and fill

activities yet. Therefore this mitigation measure is not

applicable during this reporting period.

Not Applicable

Construction waste and garbage burning are prohibited.

PLN has already conveyed a prohibition on burning of

construction waste and garbage during construction in

monthly meetings with contractors.

There is a visual management related to the prohibition

on waste burning at the construction site as shown in

Appendix 3.d






6. Construction Waste Management (HVTL alignments, substations)

Solid wastes generated from construction activities should not be haphazardly left around construction

sites.

Construction waste will be contained in a designated area on each site (tower site,

substation).

Wastes will be routinely collected and disposed of at safe waste disposal facilities indicated by the

District Environmental agencies

The remaining clearing materials in the form of wood

and tree roots are collected at the temporary disposal in

the construction site. Then it’s stored into the empty land owned by residents who are willing to be used as

the location of waste disposal of site clearing materials

as shown in Appendix 3.e



Construction waste burning is prohibited PLN has already conveyed a prohibition on burning of construction waste and garbage during construction in


In the implementation, there is a visual management

related to the prohibition on waste burning at the

construction site as shown in Appendix 3.e.



7. Domestic Waste Management (HVTL alignments, substations)

Temporary worker camps will be required to be provided with appropriate sanitation facilities,

including water supply, and washing facilities,

temporary toilets, and waste containers.

The temporary worker of the contractor’s camp is a rented house from the local people, which has been

equipped with good sanitation facilities including

adequate water supply obtained from groundwater,

washing and toilet facilities, and a trash bag to collect

domestic waste as shown in Appendix 3.f.



Domestic waste will be routinely collected and disposed of at safe waste disposal facilities

Domestic garbage of workers collected in trash bag has

been discharged to the nearest final disposal from the

worker camp ie; Sei Kosak and Sanggau final disposal

as shown in Appendix 3.f

Toilets should either by of a pit type that are at least 20 m from any water body, or porta-potty

type. If the latter, toilets should be emptied on a

regular or as needed basis, and the effluent

disposed of at an approved waste disposal facility.

The Contractor does not develop the sanitation

facilities, and therefore this mitigation requirement is not

applicable.

Worker camp sanitation facilities should developed in consultation with relevant local authorities and

has all required local, province and national

The rented house has sanitation facilities; therefore the

requirement of this mitigation is not applicable.




approvals

All worker camps should be decommissioned when it is no longer required and restored to their natural

condition.

Since the temporary worker camp is renting local

people house, so, there is no requirement to conduct

the mentioned restoration. Therefore, this mitigation

requirement is not applicable.

Garbage burning is prohibited. PLN has already conveyed a prohibition on burning of construction waste and garbage during construction in


In the implementation there is a visual management

related to the prohibition on waste burning in the project

as shown in Appendix 3.f

8. Roads and Infrastructure Impacts (HVTL alignments, substations)

A mapping of the locations of expected heavy equipment mobilization is needed versus

settlement area locations. This needs inventory and

monitors the potential damage to existing roads.

The using of heavy equipment only applied to the

open storage area. Its location is far away from

settlement area.



Any damaged infrastructure, after heavy equipment mobilization, will be repaired to at least the same

standard and condition on completion of the

Project, especially caused by the transportation of

heavy equipment e.g. 150 kV power transformer.

In the site clearing phase there is no heavy

equipment mobilization, therefore there is no road damage during this period as shown in Appendix 3.g



9. Encroachment into Protected Forests, Hunting, Wood Collection (HVTL alignments, substations)

Hunting extraction by workers of forest products such

as firewood, and keeping of firearms on the Project,

will be prohibited. To avoid impact on ecological

valuable sites, habitats, natural forest, flora and fauna,

this risk should be particularly be monitored along the

ecologically sensitive alignments of the Transmission

line: along the 35 km between Tayan and Sosok where

the alignment passes close by secondary forest within

production forest reserves; along the alignment which

runs close (3.5. and 11 km) to the primary forest within

Gunung Tiong Kandang and Gunung Sanggau; and

along the alignment which passes close (1.5 km

In accordance with letter from the Ministry of Forestry

No.S386 / BPKH.III-2/2015 dated May 13, 2015

regarding the Result of Technical Review of the

Function of Forest Areas Against the location of SUTT,

West Kalimantan Province stated that the location of

the Tayan – Sanggau – Sekadau – Sintang HVTL plan is entirely Other Use Areas.

The Tayan, Sanggau and Sekadau substations is

located on the land owned by local residents.

In the implementation there is a visual management

related to the prohibition on encroachment into

Recreation Reserve.

project site as shown in Appendix 3.h

10. Impacts on Cultural Heritage Sites(HVTL alignments, substations)

The Project area falls closely adjacent several notable

heritage sites:

Although, it is unlikely to suffer impact from Project due to separation distance (as a mitigation

measure for these sites), Project workers should be

made aware that these sites should not be

disturbed or material extracted if visited. Project

construction traffic and heavy equipment should

also not be routed anywhere near these sites to

avoid vibration damage.

During site clearing, there is no heavy equipment

transportation activity such as transformers that have

the potential to cause vibration that can damage the

nearest cultural heritage site. Therefore mitigation

measures in this period are not applicable.

Not Applicable

The Project Transmission Line construction should also take care not to make impact on the

potential un- mapped locally important cultural

sites, such as community sacred forest groves

(Hutan Adat) and sacred grave sites (tempat

keramat). Consultation should be conducted with

local Traditional Leaders (Temengung) for each

indigenous ethnic group to identify and avoid any

such sites prior to construction of all project works.

To anticipate the existence of the potential un- mapped

locally important cultural sites, prior to the start of

construction; the contractor has coordinated with the

customary head in the Ngudas event and ascertained

no construction site that passes through this location

as shown in Appendix 3.i



11. Occupational Health and Safety (HVTL alignments, substations)


construction phase Occupational Health and Safety

Plan (OHSP) will be developed. The OHSP should:

identify and minimize, so far as reasonably practicable, the causes of potential

hazards to workers, including communicable

diseases and vector borne diseases;

provide preventive and protective measures, including modification, substitution, or

elimination of hazardous conditions, with

particular attention to live power lines, working at

height, working during thunderstorms (lightning

strikes), EMFs, and exposure to chemicals;

Provide measures for the management and

providing appropriate personal protective devices

(PPE) to minimize the risk;

submitting monthly reports including documenting

and reporting occupational accidents, diseases,

and incidents; and




Establishing emergency response procedures

including provision of first-aid kids, fire

extinguishers, and emergency call lists at

construction sites.

Relevant evident of these mitigation measures are included in Appendix 3.j

However, the EHS plan does not provide identification and minimization of potential

hazards to worker including corresponding

preventive and protective measures.

12. Community Health and Safety (HVTL alignments, substations)


construction phase Community Health and Safety Plan

(CHSP) will be developed. The CHSP should include:

procedures to identify and minimize, so far as reasonably practicable, the causes of

potential Project related hazards to local

communities, including communicable

diseases such as HIV/AIDs and vector borne

diseases;

The houses and settlements in close

Location from the Transmission line should be clearly spatially mapped in order to better

inventory and address the EMF (electro-

magnetic fields) health and safety impact risk.

An effective socialization program should

follow in this at the mapped locations to

address community concerns in regard to the

EMF effects of Transmission line operation.

specific emergency response procedures;

Relevant emergency equipment.

Protocols for emergency vehicle services;

Put safety sign.

PT Siemens does not have a separate health and safety plan for managing health and safety

risks to the community. Some health and safety

provisions as described in the OHSP (above)

are applicable for managing these risks

including of :

- Providing specific emergency response

procedures, emergency equipment. and

vehicles;

- Providing the safety sign

Relevant evident of these mitigation measures are

included in Appendix 3.j

However, the EHS plan does not cover the

procedures to identify and minimize, so far as

reasonably practicable, the causes of potential Project

related hazards to local communities, including

communicable diseases such as HIV/AIDs and vector

borne diseases.

The mitigation implemented with this regard is partially compliant with the

mitigation requirements.

14. Physical Cultural Resources (HVTL alignments, substations)

. Awareness to all workers concerning chance find

physical cultural resources during construction

implementation:

If physical cultural resources are encountered during the construction phase, all works at the find

site should be immediately halted.

The find should be assessed by a competent expert, and procedures to avoid, minimize or

mitigate impacts to the physical cultural resources

should be developed by the expert in cooperation

with the relevant local heritage authority,

proportionate to the value of the resource in

question and the nature and scale of the Project’s potential adverse impacts on it.

The find should be assessed in consultation with local Traditional Leaders

(Temenggung) for each indigenous ethnic group

to identify the local cultural significance and

obtain guidance on what follow-up actions to

conduct under supervision of local communities.

Work should not begin until the procedures to avoid, minimize or mitigate impacts

to the physical cultural resources have been

implemented.

In case avoidance is not feasible, no alternatives to removal exist, and the Project benefits outweigh

the anticipated cultural heritage loss from removal;

the physical cultural resource should be

removed and preserved according to the best

available technique.

A chance find procedure from PT Siemens has been

developed on EHSP document page 50 chapter 5.32

about Unexpected discovery. But the contractor has

not conducted the awareness to the employee yet

regarding this procedure.

Relevant documents related to this mitigation are

shown on Appendix 3.k
