2. Environmental Monitoring Program
2.1 Scope of works
The construction, operation, and maintenance of MV sub-transmission lines along
rural roads in Cambodia will have an insignificant impact on the local environment.
Environmental mitigation measures normally associated with internationally
recognized good engineering practice will be implemented to ensure that potential
environmental impacts of the Project are avoided or minimized to acceptable levels.
Mitigation measures are presented: The major tasks for the environmental
monitoring in construction stage include:
· Field monitoring on contractor’s environmental mitigation measure
performance to avoid and minimize negative social and environmental
impacts;
· Potential environmental impacts that could occur during each Project
stage;
· Guidance to Contractor’s personnel on environmental monitoring aspect,
in the field practice;
· Recommend to contractor to implement all EMP recommendation and
other environmental safeguards in construction contract documents;
2.2 Methodology
In the construction stage, site observations are conducted for monitoring the
implementation of environmental mitigation measures. Site monitoring is carried out
using environmental monitoring matrix and public perception interview (directly
asking the questions to the project workers and people living nearby the project
sites). This EMP Monitoring Report presents overall assessment of the Project’s
compliance with the EMP and also provides conclusion and recommendations going
forward.
Environmental monitoring consisted of routine systematic checking to verify whether
appropriate mitigation measures have been implemented effectively during each
Medium Voltage Sub-Transmission ELECTRICITÉ DU CAMBODGE Expansion Sector Project, Package 1&2
Monitoring Report #2 3
stage of the Project. The Environmental Safeguard Specialists of Project
Implementation Consultant (PIC), with support from EDC’s Social, Environment and
Public Relations Office (SEPRO) monitors the implementation status of the EMP,
including identifying any non-compliance, proposing actions and a timeline for
rectifying deficiencies and following up on the status of previous corrective actions.
Throughout the construction period, the PIC Environmental Specialists in
consultation with SEPRO have prepared quarterly environmental monitoring reports
to check the performance of compliance with ADB’s guideline and applicable
government laws and supervise implementation of environmental mitigation
measures carried out by contractor and the reports are submitted to EDC and ADB,
The reports includes a summary of the results of site inspections and provides
recommendations on key issues or concerns that need to be resolved.
The monitoring program will be done monthly in order to make the quarterly report.
So, every 3 months will submit one report.

3.3 Summary of Inspection Activities
The EDC-SEPRO/PIC personnel for environmental and technical supervision regularly
visit the construction sites and monitor the safeguard compliance of the contractor. The
monitoring activities were as followings:
· Assess their performance of environmental safeguards implementation on
site;
· Examine, request, and supervise the Contractor in its implementation of traffic
management methods within the site and at the road crossings;
· Instruct and supervise the Contractor to carry out the environmental and
social management plans in accordance with the mitigation measures listed in
the EMP;
· Monitor and document dust and noise mitigation measures, solid waste
management and site clean-up carried out by the Contractor.
The contractual agreement between EDC and the contractor indicates that the
contractor shall undertake mitigation measures to avoid and minimize negative social
and environmental impacts. The Environment Management Plan was therefore
enclosed in the contractual agreement of civil works.
The Bidding Documents and the Contractual Agreement include provisions of safeguard
requirements to ensure that EMP and the Environmental Protection Commitment (EPC)
are being adhered to during the design and construction stage as following monitoring

Monitoring Report #2 22
a.3 Surface and Ground Water quality
During field observation, no significant water body was found along the ROW. No
impact on surface and groundwater quality occurred as most earthworks were carried
out during the dry season.
a.4 Soil erosion
No soil erosion due to planting of poles occurred during the monitoring period. On the
other hand, the contractor properly reinstated the sites by backfilling and compacting
the foundation of poles and underground cable trenches.
B. Natural resource
Installation of underground cable was carried out in accordance with requirements of
APSARA authority to minimize impact on existing physical cultural resource in the
Angkor Protected Landscape where trees are not allowed to be cut or trimmed and no
machineries are to be used. Digging and lying of cables are done using manual labor.
Some trees that are located in ROW in front of residential properties were trimmed and
cut to obtain minimum safety clearance with consent from owners who signed voluntary
contribution forms.
C. Waste management
c1. Solid waste
Construction debris were found at some sites, however site cleanup was done soon
after works completed.

c2. Liquid waste
No liquid wasted is generated from both underground and overhead construction
activities.
D. Social Resource
d1. Cultural Heritage
Experienced site manager is staffed by Electricity of Siem Reap to supervise the
construction of underground cable in Siem Reap. No chance find was encountered
during the reporting period. Extra efforts have been made by EDC to avoid impact on
physical cultural resources within Angkor Protected Landscape.
d2. Traffic
During site visit, no traffic congestion and accidents were caused by construction
activities. However, inadequate warning by placing traffic diversion signs were noted
especially around crane truck during offloading concrete poles along the roads at some
sites. On-coming traffic was affected and created risks of accidents. Therefore, PIC
recommended contractor to put appropriate warning signs such as construction cones
around work sites and warning light at dusk to prevent any accident.
Figure 3.5.2 (d2): Construction Cones used as Traffic Signs
d3. Safety
Adherence to Health and Safety was observed at most sites where workers were found
properly wearing Personal Protective Equipment (PPE) such as hard hats, reflective
vests. However, this measure still needs to be enforced at some sites. PIC will

Monitoring Report #2 25
a.2 Noise disturbance and Vibration
According to the project activities, noise and vibration were not identified. Noise from
construction vehicles and installation works is limited to a particular time and space. PIC
advised the contractor to minimize/avoid stationing equipment that generates noise near
health center, school, pagoda and residential areas.
However, machinery operator for cable wire installation shall have the ear protected
tools due to the noise level over 70 dB(A). So, contractor shall consider to find the
machineries with noise and vibration protection and provide the noise protected tool to
workers who work close to this. Moreover, it shall teach them how to use this, too.

a.3 Surface and Ground Water quality
According to project nature, it may not affect the surface and ground water quality in
and surrounding the project sites. In reality, due to field observation, no significant water
bodies were found along the ROW of overhead and underground MV. No impact on
surface and groundwater quality occurred as most earthworks were carried out during
the dry season.

a.4 Soil erosion
As shown in figure 3.5.2 (a3) above, soil erosion may not have much concerned due to
planting of poles occurred during the monitoring period. On the other hand, the
contractor properly reinstated the sites by backfilling and compacting the foundation of
poles and underground cable trenches.

After works, contractor did the good job to compress well to avoid any eroding by wind
and rain as above figure.
B. Natural resource
Digging and lying of cables are done using manual labor. The route line of underground
was flexible due to the condition of trees along the road side. Thus, there was no
changes for installation of underground cable was carried out in accordance with
requirements of APSARA authority to minimize impact on existing physical cultural
resource in the Angkor Protected Landscape where trees are not allowed to be cut or
trimmed and no machineries are to be used. Some trees that are located in ROW in
front of residential properties were trimmed and cut to obtain minimum safety clearance
with consent from owners who signed voluntary contribution forms.

C. Waste management
c1. Solid waste
Construction debris were found at some sites, however site cleanup was done soon
after works completed.

c2. Liquid waste
No liquid wasted is generated from both underground and overhead construction
activities.
D. Social Resource
d1. Cultural Heritage
As the previous, experienced site manager is staffed by Electricity of Siem Reap to
supervise the construction of underground cable in Siem Reap. No chance find was
encountered during the reporting period. Extra efforts have been made by EDC to avoid
impact on physical cultural resources within Angkor Protected Landscape. So, EDC,
PIC and Contractor is working very closed for all of dredging works and other works in
the location of ASARA area.
d2. Traffic
The boat signs of Worksite were installed in the worksite to alert local people, drivers,
and tourists know for purpose of avoiding any accident to them because of the project
activities. Also, during site visit, no traffic congestion and accidents were caused by
construction activities. However, inadequate warning by placing traffic diversion signs
Medium Voltage Sub-Transmission ELECTRICITÉ DU CAMBODGE Expansion Sector Project, Package 1&2
Monitoring Report #2 29
were noted especially around crane truck during offloading concrete poles along the
roads at some sites. On-coming traffic was affected and created risks of accidents.
Therefore, PIC recommended contractor to put appropriate warning signs such as
construction cones around work sites and warning light at dusk to prevent any accident.
Figure 3.5.2 (d2): Construction Cones used as Traffic Signs (Jan 2017 in Siem Reap province)
d3. Safety
Contractor carried out the good job after PIC advised for Personal Protective Equipment
(PPE). Health and Safety was observed at most sites where workers were found
properly wearing Personal Protective Equipment (PPE) such as hard hats, reflective
vests. However, this measure still needs to be enforced at some sites. PIC will
continuously check the use of safety equipment and improve compliance to Health and
Safety at all sites. Site inspector from EDC was working much closed with contractor for
patrolling on the PPE too.

4. Conclusion and Recommendations
4.1 Conclusion
Contractor was working on the good practice for most implementation work for this
Package. However, all of changes and updated route lines and types of wires shall
inform to PIC and EDC to avoid any late to implement the work.
4.2 Recommendations
As the results of site inspection on environmental issues based on the Environmental
Monitoring Matrix, the environmental safeguard specialist recommends in following
points to the contractor to take action for the next month:
1. The contractor should practice a simple, common-sense traffic management
plan. This should include: 1) placing traffic/warning signs i.e. “Construction in
Progress” and creating temporary fences or enclosures by placing traffic cones,
also called pylons around parked construction vehicles providing visibility to on-
coming motorists; 2) employ traffic control persons to direct traffic during
offloading of poles, especially in areas of Angkor Protected Landscape (APL).
2. all of the safety tools must immediately provide to all project workers/staffs in
the working to ensure all the workers are properly use ( as safety hats, safety
boots, gloves…) during working time.
3. Contractor should adequately provide PPEs to workers; and enforce the H&S
guidelines as specified in the EMP. Foreman/Site Manager to regularly give
toolbox talk on H&S, site cleanup to workers before works begin.
4. Contractor should follow and regularly implement a simple Waste
Management Plan. This should include: 1) site clean-up soon after works are
finished; 2) regular toolbox talk which includes site cleanup and chance find
procedure to be followed at underground cable sites in APL; 3) upon completion
of construction works, ROWs should be restored to its original or better
condition.

5. Machinery operator for cable wire installation shall have the ear protected
tools due to the noise level over 70 dB(A). Also, contractor shall teach them
how to use this, too.
6. Contractor shall work very closed with EDC before and after energize the
electricity to the project for testing or any to avoid any accentual matter from this.
