1. General Background

1.1 Project overall

The GMS Rehabilitation of the Railway in Cambodia (RRC) involves two lines, Southern

Line and Northern Line. Southern Line connected from Phnom Penh to Sihanoukville with

total length of 265 km, and Northern Line connected from Phnom Penh to Poipet (Thai

border) with total length of 386 km.

The project is under management of MPWT. The design and construction supervision

consultants is NIPPON KOEI CO.,LTD in association with JARTS. The construction

contractor for RRL1 (Southern Line) and RRL2 (Northern Line) is TSO-AS & NAWARAT

Joint Venture (France and Thailand), but for RRL1, JV partners were changed to TSO-

SPCC Consortium since October 21, 2011).

1.2 Project progress

The project activities include design, platform improvement, bottom ballast relay, sleeper

and track relay, sleeper tamping, top ballast relay, welding (for Southern Line), and

rehabilitation/reconstruction some culverts in both lines, rehabilitation of bridge in SL, and

reconstruction of drainage system in Sihanoukville station.

Based on the monthly progress report No. 62, March 2013, the both project lines (Southern

and Northern Line) rehabilitation work as actual overall progress stand same as last month

due to remedial works after the inspection for the snagging list.

1.3 Purpose of the report

As full implementation of the IEE procedure of the project, the environmental specialists of

Construction Supervision Consultant (CSC) have two main roles as following:

- supervise the monitoring of implementing mitigation measure of the contractor

during the construction stage, and submit the environmental monitoring report to

MPWT-PIU and ADB;

- provide environmental management training (class room and field) to MPWT-PIU

staffs and key persons of contractor who responsible on field of environmental

safeguard.

The environmental monitoring report is to follow up the contractor’s implementation on

environmental mitigation measure in construction stage as stated in EMP and other

environmental safeguards in construction contract documents. Guidance and instruction will

be prepared to enforce the contractor to follow the environmental mitigation measure as

stated in IEE report and construction contract documents.



2. Environmental Monitoring Program

2.1 Scope of works

The major tasks for the environmental monitoring in construction stage include:

Reviewing the environmental report in previous month that prepared by

contractor (TSO/SPCC);

Field monitoring on contractor’s environmental mitigation measure performance

in both project lines (Northern and Southern lines);

Guidance to MPWT’s staff/PIU and TSO’s environmental engineers on

environmental monitoring aspect, in the field practice;

Recommend to TSO to implement all EMP as stated in IEE report and other

environmental safeguards in construction contract documents; and

Instruct TSO/SPCC to take an action to mitigate or rectify on other issues that

find out in the construction stage.

2.2 Methodology

Two simple ways have been applied in this monitoring stage, reviewing the monthly

environmental reports that prepared by TSO/SPCC and site investigation in both project

lines.

Reviewing environmental report of contractor:

- Screen the result of environmental mitigation measure performed by

contractor, and the issues that happened in the field;

- Review the result of rectifying or improvement activities on the environmental

issues; and

- Find out the compliance with EMP in IEE report and Cambodia’s regulation

and law.

Site monitoring: Use environmental monitoring matrix, borrow pit matrix, hearing

(directly ask the question to the project workers and people living nearby the

project sites), and visual: During the field observation on environmental

mitigation measure that implemented or rectified by contractor (TSO/SPCC), the

CSC/Environmental Specialist used the environmental monitoring matrix for

construction phase (Annex 1). Visual and hearing methodology also has been

applied for other environmental monitoring items, and degree of impact have be

recorded and photograph to proof the impacts (good or bad) are used.



3. Results of Environmental Monitoring

3.1 Reviewing on Environmental Report of TSO

In April 6, 2013, CSC/NK received Contractor’s Monthly Progress Reports for December

2012 and January-February 2013 for Southern Line (RRL1: Phnom Penh-Sihanaoukville).

In above three Contractor’s monthly progress report had included of security, safety and

environmental status of the project in appendix E.

There is no TSO’s Monthly Progress Report for the Northern Line (RRL2: Phnom Penh-

Poipet) since July 2012, due to contractor has stopped all site activities at the end of July

2012.

3.1.1 Summary of Contractor’s Environmental Report

In Contractor’s Monthly Environmental Report for February 2013 had been described some

points in following:

- Security Guards;

- Safeties and Environment issue; and

- HIV & Human Trafficking.

Security Guards: There are 38 security guards in total to maintain security in storage

areas, workshops, and project office.

Safety and Environmental Issues: The report described that the PPE include safety

shoes, rain coats, working gloves, safety glasses, and high reflector vest. Report also

showed some bar-charts on safety training that the workers gained including first aid

training.

HSE manager reminded to TSO to replace or refill the fire extinguishers that equipped in

workshop at Kampot and Sihanoukville station. Also reminded to supervisors, site

managers as well as engineers do not allow the workers who not wearing PPE.

HIV & Human Trafficking

The training on HIV/AIDS and Human Trafficking awareness had been provided to

workers and community memebers in Trapaing Raing village, Angkor Chey district,

Kampot province. The training was conducted by SUN SHINE ORGANIZATION on 15-

16 February 2013. The total attendant is 129 persons. The topics have been used in the

training are:

- Mode of transmission of HIV/AIDS

- Mode of not transmission of HIV/AIDS

- Prevention measures

- Suspected signs of HIV/AIDS

- Condom use demonstration

- Migration and human trafficking in relation to HIV/AIDS

- Drug use and HIV/AIDS

- Role of construction workers and community members in HIV/AIDS

prevention



3.2 Field monitoring by CSC/Local Environmental Specialist

The task work includes follow up on the environmental issues and corrective action by the

Contractor (TSO/SPCC) in SL lines, and investigation on other environmental items that

had been occurred by the project construction activities.

The field observation had been done on 19 and 21 April, 2013 for Southern Line from Touk

Meas to Sihanoukville port. Some reports from NK’s site inspectors were collected during

field monitoring.

The environmental issues and environmental mitigation measure were described in

following paragraph, and the field recorded is included environmental monitoring matrix

(Annex 1) and borrow pits matrix (Annex 2).

3.2.1 Southern Line

The field monitoring in Southern Line was carried out from Touk Meas station to

Sihanoukville port (as phase 2 of the RRL1). The result of environmental condition can be

described in following:

1. Leaks and spills of hazardous material: The fuel storage facilities at Kampot and

Sihanoukville station are very good installation (concrete platform and wall, and

security equipment and fence), see figure 3.2.1-1a. Both stations had an incharged

person for daily operation and maintain including security and safety.

The monitoring work in this month found that the fuel storage places in Sihanoukville

and Kampot stations are well managed of leakage fuel, no sign of spillage on the

ground and on the concrete floor.

at Kampot station at Sihnoukvile station

Figure 3.2.1-1a: Fuel storage facilities

TSO not provide yet the spilling kit to both fuel storage places, this issue was

happened since September 2012. The incharged persons in both fuel storage areas

used second-hand clothes to maintain spilling oil and grease in place.



2. Soil erosion: In generally no sign of soil erosion during the site monitoring in this

month, most of the embankment are covered by vegetation that naturally grew and

grass planted by contractor since July and August 2012. On the other hand there had

not earth work along the embankment at all.

3. Borrow pits/quarries:

TSO had been improved some borrow pits as recommended and instruction in many

month including last month. For instance the borrow pits PK140+600, PK140+650,

PK141+000, and PK168+950 are re-fenced, figure 3.2.1-3a. The borrow pit at

PK119+780 (behind Touk Meas high school) and the borrow pit at PK168+960 are re-

filled, figure 3.2.1-3b. The detail of the improvement borrow pits are described in

borrow pit matrix Annex 2.

4. Water quality

During field observation there was not signed of water laden into the rice field or

water body nearby the embankment of the railway, due to very small track work, level

crossing and in front of the Sihanoukville port, no earth work activities at all.

5. Air pollution

In this month there is very small construction activity, only level crossing construction

in front of the Sihanoukville port and track work in this place. So polluted air and dust

come from construction machineries and relay track are minor.

6. Noise disturbance

Noise disturbance is happened from the construction machinery such as excavator,

bulldozer, ballast regulator, sleeper tamping machine, and transportation trucks of the

project. In this month, there are small amount of construction machineries on the

platform for track work and level crossing construction in front of Sihanoukville port.

Noise disturbance was found at breaking concrete road site for construction level

crossing in front of Sihanoukville port, and no significant impact to local community

except operator of rock breaking machine.





7. Waste management

The workshops and storage areas in Kampot and Sihanoukville station have been

improved and equipped with garbage bin, figure 3.2.1-7a. Most of the construction

sites are well managed of solid waste as well as spoil soil, during site observation in

April 2013.

The solid waste at workers camp at railway pile in Sihanoukville station and at

PK263+780 near level crossings had been improved and garbage bin and camp

representative have been provided. In figure 3.2.1-7b shows the condition of solid

waste management in both workers camps.

8. Liquid waste generation/Drainage

The liquid waste generation from the project is wastewater from the bathing and

flushing toilet. Generally, the workers camps shall be equipped with bathing room and

toilet. The bathing water shall be drained into the small channel nearby the camps or

connected to the public sewer or open ditch along the road ways. The toilet is built

with storage flushing water concrete ring (two concrete rings with diameter 1meter).

Same as last month CSC found that the worker camps at rail storage/pile in

Sinaoukville station have not drainage system, figure 3.2.1-8a. All bathing waters are

flushed on the open space surround the water tank, so some muddy during bathing

was happened.

9. Traffic problem

On date of the field observation, the monitoring team did not see any traffic

congestion as well as accident that caused by the project activities. Most of the

construction activities are on the platform of railway at PK215, in front of Warehouse,

and at PK264 level crossing in front of Sihanoukville port.

On the other hand, the level crossing sign and barrier are not yet put in

implementation for the phase 2 of RRL1 project (Touk Meas to Sihanoukville port).

The contractor TSO&SPCC just provide facilitator and traffic sign at advance and

behind the construction site where across the level crossing.

10. Damage road and bridge

Damaged culvert or bridge was not found on date of field environmental monitoring.

11. Adequacy of facilities/equipment for workers

As normal provision, the workers camps shall be provided with wooden shelf/bed,

good plastic roof and wall, water tank, garbage bin, lighting (battery + lamp), and

toilet.

During the field monitoring in April 2013, found that the workers camps at rail pile in

Sihanoukville station and at PK263+780 had garbage bin and camp representative to

take care security and keep camp clean, figure 3.2.1-7b. However TSO not yet

provide lighting facilities, first aid kit, and latrine. The workers camp at PK263+780

had one latrine but not function due to improperly installation and wrong location.

Workers camp at Trapeang Rpov station (PK198+500) ready removed on 7 April 2013

due to finish the works in place.



12. Safety

The TSO’s workers of who are working on track-worked and at level crossing

construction in front of the Sihanoukville port equipped with boots and light jacket,

figure 3.2.1-12a.

However two workers whom work for breaking concrete/bitumen for building level

crossing at PK 0+220 (in front of Sihaoukville warehouse) had not dust musk,

goggles, and ear plug, and they complained that TSO did not provide these kind of

PPE to them, figure 3.2.1-12b. Concerning to this issue CSC had instruct TSO in last

month to provide properly PPE to workers in appropriate type of work, but TSO did

not implement yet.

All the workshops and storage places have been equipped with extinguisher capacity

of 8kg (at least 2 bottles), figure 3.2.1-12c.

13. Construction-related complaint

There is no construction related complaint in this month (April 2013). The procedure

of weekly salary of the workers had been improved, worked 3 weeks paid 2 weeks.

Moreover the people who living close to the borrow pits at PK168+950, PK168+960,

PK119+750, and PK119+780 are happy due to those pits were improved (re-filled and

re-fenced) by Contractor before Khmer New Year as promising.



3.2.2 Northern Line

There is not activity in the Northern Line, TSO stopped all the activities and moved all

project’s equipment from the site since 21 July 2012. The environmental condition is

same as September 2012.

4. Summary and recommendations

4.1 Summary

The result on environmental monitoring in April 2013 can be summarized as following:

(1) CSC/NK received Contractor’s Monthly Progress Reports for December 2012 and

January-February 2013 for Southern Line (RRL1: Phnom Penh-Sihanaoukville) on 6

April 2013. In monthly progress report had been included monthly environmental

report as Appendix E.

(2) Good fuel storage facilities had been provided/installed (concrete platform and wall,

and security equipment and fence) with security fencing, and not sign of

leakage/spillage. The incharged persons in both fuel storage areas used second-

hand clothes to maintain spilling oil and grease in place. TSO not provide yet the

spilling kit to both fuel storage places, this issue was happened since September

2012.

(3) 6 borrow pits which are recommended to improve as described in borrow pit matrix

in EMR for March 2013, TSO had implement as following:

Borrow pits PK140+600, PK140+650, PK141+000, and PK168+950 are re-

fenced.

The borrow pit at PK119+780 (behind Touk Meas high school) and the

borrow pit at PK168+960 are re-filled.

(4) No sign of soil erosion during the site monitoring during this month and on the

other hand there is small track work and level crossing construction.

(5) No sign of water laden into the rice field or water body nearby the embankment of

the railway.

(6) During field observation CSC not meet the workers work in tamping machine and

ballast regulator, but noise disturbance was found at breaking concrete road site for

construction level crossing in front of Sihanoukville port, and no significant impact

to local community except operator of rock breaking machine.

(7) Most of the construction sites are well managed of solid waste as well as spoil soil,

during site observation in April 2013. The solid waste at workers camp at railway



pile in Sihanoukville station and at PK263+780 near level crossings had been

improved and garbage bin and camp representative have been provided.

(8) The drainage system in Sihanoukville station is improved, but some workers camp

have not provide drainage trench at all. Same as last month CSC found that the

worker camps have not drainage system. All bathing waters are flushed on the open

space surround the water tank, so some muddy during bathing was happened.

(9) There is not traffic problem during site monitoring as well as the report from site

inspector in April 2013.

(10) There is not damaged road and culvert by project construction activities.

(11) In April, the workers camps at rail pile in Sihanoukville station and at PK263+780

had garbage bin and camp representative to care security and keep camp clean.

However TSO not yet provide lighting facilities, first aid kit, and latrine. The workers

camp at PK263+780 had one latrine but not function due to improperly installation

and wrong location.

(12) Most of TSO’s workers are equipped with PPE (boots, light reflection jacket, and

helmet. However two workers whom work for breaking concrete/bitumen for

building level crossing at PK 0+220 (in front of Sihaoukville warehouse) had not

dust musk, goggles, and ear plug, and they complained that TSO did not provide

these kind of PPE to them. Actually this issue CSC had instruct TSO in last month to

provide properly PPE to workers in appropriate type of work, but TSO did not

implement yet. All the workshops and storage places have been equipped with

extinguisher capacity of 8kg (at least 2 bottles).

(13) There is no construction related complaint in this month (April 2013). The

procedure of weekly salary of the workers had been improved, worked 3 weeks

paid 2 weeks. Moreover the borrow pits at PK168+950, PK168+960, PK119+750,

and PK119+780 were completely improved before Khmer New Year.

4.2 Recommendations

As requirement of the EMP in IEE report and issue founding during environmental monitoring in this month, the CSC’s environmental specialist recommends in following points:

1. Contractor must immediately provide spilling kit to instead of used-cloth to incharged

person in each fuel storage station. 2. Contractor must immediately provide latrine, first aid, and lighting facilities to all

workers camps of the RRL1 project. In case of Contractor fail to comply requirement measure as stated above MPWT will deduct cost value from Contractor’s interim payment certificate (IPC).

3. Contractor must provide immediately eye glass, ear plug, and musk to workers are

working to break rock/concrete/bitumen.



4. Contractor must properly implement all environmental mitigation measure in construction stage as setting IEE report and other environmental safeguards that stated in construction contract. In following paragraph are some mitigation measures have been described in EMP (construction phase) in Appendix A of IEE report, November 2006, page 58-73.
