1.0 Introduction

1.1 Project description

The Ceylon Electricity Board (CEB) is planning to build and operate a semi-dispatchable wind farm of 100 MW capacity and associated 220 kV transmission line (29.1 km) in the Mannar region under financial assistance of the Asian Development Bank (ADB) under (i) Wind Power Generation Project, and (ii) Green Power Development and Energy Efficiency Improvement Investment Program – Tranche 2. The wind energy conversion systems (WECS) would be selected for the proposed wind farm to generate clean electrical energy sustainably. The proposed Wind Power Park will be located in the southern part of Mannar Island from Thoddaveli for a length of about 12 km along the coast. A row of 30 (+3 locations set aside for the time being) turbines will be installed parallel to the shoreline. The proposed wind farm has excluded the areas belongs to Adam’s Bridge Marine National Park which has been declared in 2015. The nearest village is located about 800 m away from the second row of wind turbines. Also, several Navy camps/ Navy observation points, boat landing sites, Ma-del hauling sites, and fishermen vaadi/camps (seasonal) and a tourist hotel are found within the wind farm block.

1.2 Objectives of the project

The components of the project are as follows:

1. Sri Lanka: Wind Power Generation Project (Project No. 49345-002): Integrate the 100 MW power from the Mannar Wind Power Generation Project to National Grid network of Sri Lanka.

2. Green Power Development and Energy Efficiency Improvement Investment Program (GPD&EEIIP) - Tranche 2 (Project No. 47037-005)

- Package 2: Lot A - Construction of Nadukuda 220/33 kV Grid Substation & Augmentation at Mannar 220/33kV Grid Substation

- Package 2: Lot B1 - Construction of 30 km long Mannar–Nadukuda 220 kV transmission line

The impact of the investment project will be increased access to clean and reliable power supply enhanced by 2025. The outcome will be clean power generation increased. The outputs of the investment project are:

(i) Wind power generation increased. This output consists of three subcomponents: (i) 100 MW wind farm constructed in Mannar Island in the Northern Province; (ii) wind park infrastructure developed that involves construction of the wind park's internal medium voltage infrastructure, internal cabling, access roads, and other arrangements; and (iii) a renewable energy dispatch control center established to forecast, control, and manage intermittent 100 MW wind power generation.

(ii) System reactive power management improved. This includes installation of 100 megavolt-ampere reactive (MVAr) reactors at the 220 kilovolt (kV) level at the Anuradhapura grid substation in the North Central Province and a 50 MVAr reactor at the 220 kV level at the Mannar grid substation in the Northern Province to manage voltage levels within the planning limits and practical operational requirements, and ensure reliable operation of the wind park.

(iii) The capacity of CEB in project engineering design review and supervision strengthened. Expert consultancy services will be procured to strengthen CEB's capacity in project engineering design, review, and supervision. These advisory consultancy services will assist CEB in ensuring engineering oversight of wind turbine installation, commissioning and testing activities, and technical certification of contractor's activities throughout the construction period.

1.3 Environmental category as per ADB Safeguard Policy Statement (2009)

ADB is extending loan assistance to Sri Lanka’s power sector for Green Power Development and Energy Efficiency Improvement Investment Program with a focus to identify the transmission and distribution projects for the evacuation of renewable energy (wind and solar) parks/ projects and overall improvement of network efficiency. The following are the Project Categorization based on the ADB SPS (2009):

Safeguard Categories

Environment A

Involuntary Resettlement B

Indigenous Peoples C

1.4 Monitoring requirement

The proposed project is located close to the three protected areas: viz., Vankalai Sanctuary, Adams Bridge Marine National Park and Vidathalathivu Nature Reserve. The transmission line passes through Vankalai Sanctuary (7.5 km) which is legally protected under the Fauna and Flora Protection Ordinance and is also designated as a wetland of international importance (Ramsar Sites) under the Ramsar Convention. Due to the location sensitivity of the proposed project, it is considered as a ‘Category A’ project under the ADB Environmental Safeguard project categorization (ADB SPS, 2009). Accordingly, an Environmental Impact Assessment (EIA) was carried out by the Ceylon Electricity Board (CEB), who is the project proponent. In the EIA report, applicable laws/legislation and policy framework have been reviewed, and environmental mitigation measures have been recommended for implementation during construction and operation stages of the project and its associated facilities. Accordingly, a comprehensive Environmental Management Plan (EMP), and Environmental Monitoring Plan (EMoP) were provided with guidelines for detailed construction method statement to be prepared by the Contractor (and sub-contractors). Also, a Biodiversity Management Plan (BMP) has been formulated to ensure no net loss of biodiversity. This Biodiversity Management Plan (BMP) falls under the EMP and is a part of the package of activities designed to meet the requirements of ADB’s Safeguards Policy Statement (SPS) 2009.

1.5 Objectives of the Assignment

The objective of this assignment is to monitor the implementation of relevant mitigation measures recommended by the EMPs/EMoPs and implementation of measures proposed in the BMP for three years during construction and further two years during the operations.

1.6 Objectives of this Report

The Environmental Specialist and the Biodiversity Specialist have now mobilized and commenced the work on External Monitoring of implementing the EMP, BMP and the EMoP by the Project Proponent, Contractors, and sub-contractors of the Mannar Wind Power Generation Project and Package 2 Lot A and Lot B1 of the GPD&EEIIP. The Consultants first met the officials of the Ceylon Electricity Board and collected the documents prepared which described the EMP, BMP and the EMoP for each of the main components of the project. Subsequently, they visited the project areas in Mannar on 19th and 20th October 2019.

This report serves as the Quarterly Report No. 2 (covering the period of 1 July 2019 to 30 September 2019) of the External Monitoring of the implementation of the EMP, BMP and EMoP. The Quarterly report submitted for 1 April 2019 to 21 June 2019 mainly concerned

Executive Summary

The Environmental Impact Assessment (EIA) of this project has carefully reviewed by the Vestas. As

first step to comply the EIA recommendations, the Construction Method Statement (CMS) has

prepared and submitted to the CEB. Further, the SEMP submitted to CEB.

This monthly report is prepared as per the request and outline provided by the contractor for civil

activities for the month of July 2019. An environmental and social safeguard officer with the HSE

team has established to perform this task. Around 65 site induction meetings have conducted to the

staffs during this period. One collective program conducted to a sub-contractor on the

environmental and social safeguard aspects, ten staff officers has participated.

Preparatory works of main access road, accommodation building and admin building area and soil

stocking were the main civil activities during July 2019. No any exceedance of environmental

standards was identified.



1.0 Introduction

1.1 Brief Project Description

Ceylon Electricity Board is implementing a semi-dispatchable 100 MW wind power project in Mannar

with the loan assistance of Asian Development Bank. The main benefit from the project is electricity

generation from wind power of about 345 gigawatt hours (GWh) per year, which will be avoiding

electricity generation from conventional power plants such as thermal power.

The project is comprised the construction of the following major components:

1. A total of 30 wind turbines with a turbine specification and layout to comply with

environmental and social aspects;

2. A collector substation and control building;

3. The collector cables, step-up transformers and switchgears and accessories;

4. Supporting infrastructure will consist of access roads, temporary storage facilities, building

and staff accommodation facilities, etc.

The proposed wind power farm is in the southern part of Mannar Island from Thoddaveli to Pesalai

South, with a length of about 12.5 kilometers (km) along the coast. The first row of up to 30 turbines

will be placed about 150 meters (m) to 160 m from the shoreline. The proposed wind farm has

excluded the areas coming under the Adam’s Bridge Marine National Park (by approximately 1 km)

declared in 2015 by the Government of Sri Lanka (GoSL). The nearest village is about 800 m away

from the second row of wind turbines. Several Navy camps and Navy observation points, boat

landing sites, ma-del hauling sites, and fishermen vaadi/camps (seasonal), two investment cabanas,

and a tourist hotel are found within the wind farm block. Access roads to the Navy camps, fishermen

camps and fish landing sites from Mannar- Thalaimannar highway, and roads parallel to the coastline

are also found within the wind farm.

VESTAS ASIA PACIFIC A/S as a main contractor has awarded to construct the wind farm in Mannar by

the CEB during November 2018.

1.2 Project Progress Status and Implementation Schedule

Implementation Schedule

The Implementation period of the MWPP is from March 2019 to September 2020. The major activity

of this project includes, construction of access roads, rehabilitation of roads, construction of 30 nos.

I .0 INTRODUCTION

With a national goal to increase the share of the nonconventional energy in S ·

Lanka by about 20%- of"the total generated power by 2020, Ceylon Electrici-

Board initiated the construction and operation of a semi-dispatchable wind farm

of lOOMW capacity along with the financial assistance of ADB funding.

Launched as the first phase of harnessing the wing electric potential in the

Mannar region, this electrical power generating project of 375 MW capacity will

be developed under four phases. The engineering, procurement and construction

(EPC) of the project was awarded to Vestas Wind Systems A/S; a Danish

manufacturer, seller, installer, and servicer of wind turbines. Vestas is to provide

the delivery, installation and commissioning of 30 V126-3.45 Mw wind turbines

as well as civil and electrical works.

The civil works of the plant is subcontracted to Access Engineering PLC b

Vestas and the scope of the project includes dilapidation survey and geo-

technical investigations, architectural and structural design of buildings, roads

and tower foundation, pilling, construction of foundation for wind turbines,

installation of medium voltage cables, design, supply and installation of optical

fibre cables, CCTV and intercom systems, road infrastructure works, etc.

The undersigned was requested by Access Engineering PLC to provide the Site

investigation reports and to propose foundation recommendations.

2. STRUCTURE INFORMATION AND SITE DESCRIPTION

Windmills will be installed in Mannar region in beach sandy soil. Foundation will comprise -,

of Cast in-situ bored piles of 800mm diameter.

3.0 FIELD INVESTIGATIONS I

.Field investigation consisted of drilling at least one borehole at each "\vindIT'ill

location. The boreholes were advanced down to the hanuner bounce level (SPT >50)

for at least 3 continuous layers. Mobilization of drilling rigs, equipment and

personnel to the site was borne by ACCESS Engineering PLC and the undersigned

observed the investigation procedure at those sites on random basis. ACCESS

Engineering PLC was responsible to present the BH records to the undersigned with

core boxes for sample observations and further investigations.

In all overburden formations Standard Penetration Test (SPT) was conducted at an

interval of 1.5m. In those soil formations, the visual classification was carried out for

each soil type encountered.

4.0 SUBSURFACE CONDITIONS

Details descriptions of subsurface condition encountered in the site during the field

investigation is presented in the borehole longs of BH 22at 726767.254,341844.321(Appendix

A). From the results of the borehole investigations at borehole location BH 22, five major soil

layers could be identified depending on the particle size distribution and SPT values as

shown in Figure 1.

Five basic layers were identified as follows.

Layer 1 - Fine to medium sand with shell

Layer 2 - Clayey sand with shell

Layer 3 -Fine to medium clayey sand with sandstone

Layer 4 - Fine to medium clayey sand

Layer 5 - Fine to medium clayey sand with limestone

Idealized profile and assumed properties are discussed in chapter 6.

·-.o LABORATORY TESTS

ils Mechanics Laboratory of University of Moratuwa conducted the laboratory tests on the

core boxes handed over to the laboratory. All the samples handed over were tested on

_ article size distribution, natural moisture content and specific gravity tests. Those results

e attached as Appendix B. It was noted that all the samples do not contain more than 5 %

::mes. Therefore, the general classification for the entire stratum would be sand.

16.0 INTERPRET A TI ON OF THE RES UL TS OF THE SITE INVESTIGATIONS

6.1 Soil Properties

6.1.1 Soil strength and compressibility parameters

To estimate the soil strength parameters of the soil layers, ' the energy method of SPT

correction was used (Bowels, 2002). The standard blow count Nf0

can be computes as

follows.

CN = (95

T/c Modification factors (Bowels, 1996)

T/l = Er Er - Efficiency of the hammer used (taken as 55 % ) 70

Nj 0- Adjusted N using the subscript for the standard energy ratio

The estimated Nf0 together with particle size could be used to estimate the soil strength

parameters at respective depths. The estimated parameters are drained parameters for sand

and undrained parameters for clay. Conservatively the cohesion of sand arid friction angle

of clay is assumed as 0 as the above method as well as most of the other methods have been

developed either for the estimation of friction angle in sandy soil or cohesion in clayey

soil.For the soils with SPT greater than 50 (hammer rebounding soils), the field SPT N was

assumed as 50. The estimated shear strength parameters for the soil at borehole BH 22 is

given in the Ta"Qle 1.

From the results of the borehole investigations at borehole location BH 22, five major soil

layers could be identified depending on the particle size distribution and SPT values as

shown in Figure 1. The different sublayer thicknesses and properties for the borehole BH 22

are given in Table 2. The elastic modulus and the Poisson's ratio were from the local field

experience and using empirical correlations given in Bowels (2002) based on SPT values.

Furthermore, soil strength parameters for each layer depending on the local experience and

SPT values are r-ecommended for a conservative design in Table 2.

Layer 1 - Fine to medium sand with shell

Layer 2 - Clayey sand with shell

6.2Foundation Recommendations I

Due to the lateral forces and pull-out forces on the foundation due to wind forces acting on

the. blades and the tower of the windmill, when designing a foundation significant attribute

should be given to the resistance against lateral forces. Therefore, shallow foundations are

not suitable under these conditions. Hence, bored and cast in-situ piles may be used to

support the structure. ACCESS Engineering PLC further informed that the pile construction

would be cast in-situ bored piles.

6.2.1 Deep Foundations

6. 2.1.1 Estimation of static pile capacity

The general expression to determine the ultimate load capacity of a single pile in

compressionPu, canbe given according to the equation given below (Poulos& Davis, 1980).

Pu = P su + Pbu - W

Psu - ultimate shaft resistance Pbu - ultimate base resistance W -weight of the pile

where,

C -pile perimeter Ca - adhesion <Jv- vertical stress Ks- coefficient of lateral earth pressure 4>a- angle of friction between soil and pile L -length of pile shaft

Ab- area of pile base c- cohesion of soil <Jvb-vertical stress at the level of pile base y-unit weight d-pile diameter N0 Nq and Ny- bearing capacity factors

The allowable pile capacity can be obtained from the following relationship:

Ps Pbu p =~+

a SFs SFb

9

where, I

SF- safety factor commonly ranging from 2-4 or more depending on the uncertainty

The recommended design parameters (ultimate skin friction coefficient, fu and net allowable

bearing capacity, qa11) for the piles near the borehole BH 22 are presented in Table 3.The piles

shall be terminated in a strong soil layer considering the applied loads. In calculating the

skin friction in sandy soils, the overburden reduction closer to the pile due to soil arching

was considered beyond a critical depth. The calculation of the critical depth was done

considering a depth of 15B wherea pile having a diameter (B) of 0.8 m was considered in this

regard. No safety factors were considered in providing the ultimate skin friction coefficient

(f u) in Table 3. A safety factor of 1.5 for the ultimate shaft resistance is recommended. A

safety factor of 3 has been utilized in calculating the allowable base resistance from the

ultimate base resistance.

6. 2.1.2. Estimation of settlements in deep foundations

The elastic settlement of deep foundations due to the load at the tip of the pile can be

determined based on the elastic theory. The settlement at the top of an incompressible pile in

half space pile can be expressed to a sufficient accuracy using the equation below according

to Poulos & Davis (1980).

7.0 RECOMMENDATIONS

Due to the lateral forces and pull-out forces on the foundation due to wind forces acting on

the blades and the tower of the windmill, when designing a foundation, a significant

attribute should be given to the resistance against lateral forces. Therefore, shallow

foundations are not suitable under these conditions. Hence, bored and cast in-situ piles may

be used to support the structure.

During the site investigation, there was some evidence of presence of limestone fragments in

the sandy soil. However, at the depth of hammer bounce with more than SPT N 50 for three

consecutive layers, the site investigation process was terminated. At that level, there was no

such continuous presence of limestone layers with problematic cavities. In such case, design

and construction of foundations in limestone areas can possess various problems such as

subsidence and sinkholes.

Since there was no indication of very loose sandy soils and no presence of soft clay la ers in

the site, the potential for negative skin friction would be minimal.

Due to the huge bending moments and lateral forcesfrom the wind, when desi<:> g e

foundation,tensile forces and lateral forces on piles should also be taken into considera ·a

Pile testing is recommended and depending on the results recommended values ma be

revised.

EXECUTIVE SUMMARY

In the efforts to harness renewable energy in the country, wind has been identified as a source of significant

potential to generate electricity. Studies carried out by both local and international experts envisaged that 375

MW of wind capacity with 35~45% plant factor could easily be developed in the Mannar island. Accordingly,

CEB has planned to set up a 220/33kV GSS at Nadukuda in the Mannar island and a 220kV transmission line

from Nadukuda to Mannar in order to evacuate the wind power generation in the Mannar island under the

Green Power Development and Energy Efficiency Improvement Program (Tranche II) which will be funded by

ADB.

Under this project component, it is proposed; (1) to construct 220/33kV Grid Substation (GSS) at Nadukuda in

Mannar island and the augmentation of Mannar GSS. This GSS will able to absorb entire 375 MW of wind power

at this stage only 2 X 63MVA capacity transformers will be installed with the provision to install further 4 X

63MVA transformers in the future. (2) to construct a 30km of 220kV transmission line from Nadukuda GSS to

the Mannar GSS. The Nadukuda GSS will interconnect the clusters of wind plants at 33kV level and transmit the

power & energy to Mannar Grid Substation via the 30km long 220kV transmission Line.

Green Power Development and Energy Efficiency Improvement Investment Program (Tranche II) has been

launched with a focus to develop transmission and distribution projects for evacuation of renewable energy

(wind) parks/ projects and overall improvement of energy efficiency and capacity development.

Green Power Development and Energy Efficiency Improvement Investment Program is

intended to finance a series of investments in Sri Lanka. It includes generation capacity enhancement,

transmission capacity addition and distribution system strengthening installation energy efficiency measures.

The Investment Program will also finance a number of “softer” activities, including operational capacity

building and implementation supervision. The objective of the investment is to achieve increased adequacy

and efficiency of power system, including renewable energy in Sri Lanka.

Site Photos of Construction of Mannar – Nadukuda 220kV Transmission Line


Note: Completion of foundation in most of the locations acquired more time than estimated due

to heavy rainfall in the northern region. Hence the work progress is slightly low during this

quarter.

Construction in vankalai bird sanctuary

The work has been started in the Vankalai from Febreuary 2019 onwards. The Progress was slow and

Contractor unsuccessful to finnish the all construction activities due to collapsible soil, more time taken

to manual excavation process ( removal of existing foundation at N1 & O0 locations taken additional

time) and delay in obtaining the transport facilities from Sri Lanka Railways as schedule to transfort the

Materials inside the Vankalai. All construction activities are under strict supervission of CEB as per the

BMP.

7.0 Conclusions and Recommendations.

The Green Power Development and Energy Efficiency Improvement Investment Programme

(Tranche 2) Package 2 which consists of two major projects components namely Lot B1

Construction of Mannar – Nadukuda 220kV Transmission Line and: Lot A Construction of

Nadukuda 220/33 kV Grid Substation & Augmentation at Mannar 220/33kV Grid Substation

are already commenced. It has been identified the project activities associated with the

environment during implementation phase as clearing of trees along the route alignment,

excavation for installation of towers, erection of towers, civil works related to transmission

line and line stringing, excavation for building and equipment foundations in substations, civil

works and erection of equipment especially in the Vankalai sanctuary.

The impacts on the environment from aforesaid activities of the project can be categorised

as follows:

• Impact on Physical Resources (Impact on Topography, Impact on Climate)

• Impact on Environmental Resources (Impact on Air Quality, Impact on Noise Levels,

Impact on Surface Water Quality, Impact on Ground Water Quality, Impact on Soils and

Geology)

• Impact on Ecological Resources (Terrestrial Ecology, Aquatic Ecology, Ornithology)

• Impact on Human Environment (Health and Safety, Agriculture, Socio-economics,

Resettlement and Rehabilitation Cultural sites, Traffic and Transport, Interference with

other utilises and traffic)

• Waste Disposal (Solid waste disposal, Liquid waste disposal)

Environmental Safeguard Measures are being adopted to mitigate the aforementioned

impacts during the construction period in compliance with the applicable acts and the

legislation to this Project.

Comments on Environmental Safeguard Monitoring Report

Reporting Period: Q3 of 2019 (From July 01, 2019 to September 30,2019)

1. Section 1.2: The progress status of the project is given for October 2018 – December

2018. It is more appropriate to provide the progress at the end of the period that is

reported in the Environmental Safeguard Monitoring Report, i.e., end of Q3 of 2019.

2. Site Photos of Construction of Mannar – Nadukuda 220kV Transmission Line: It is

always good to provide a short description for each photograph (location, tower

number, what is the main feature that is intended to be highlighted, etc.), and the

date the photo was taken.

3. Page 5 (bottom): Indicate the number of days lost due to inclement weather, and the

implication of such incidents on the environment (e.g., flooding of the footings,

trenches, drainage problems, erosion of topsoil, etc.). Then describe what the

contracts have done to mitigate such environmental incidents.

4. Page 6 (top): Progress status of the GS: the comment (#1) that has been given

above for Section 1.2 applies here, too.

5. Site photos of the construction of the Nadukuda GS: comment #2 given above

applies here.

6. Table 2.0: Applicable Acts and Legislations to the Project:

₋ The Compliance Schedule to be corrected as the Compliance Status.

₋ It had been indicated that the Act/Rule/Notification has ‘being complied’ for all

the entries (other than for felling of trees). More explanation is required for

each entry as to how each Regulation has being complied with.

7. Section 4.0: Compliance to Environmental Management Plan

Check whether all the Project Activities and Potential Impacts for both Pre-construction and Construction Periods match with the EMP given in the EIA Report approved by the ADB.

If they do not match, please add all other entries given in the EMP proposed in the EIA Report.

8. EMP and EMoP – Pre-construction

The following are missing (baseline monitoring reports):

• Water Quality

62

• Air Quality

• Noise and Vibration Levels

• Soil testing results

Include the following:

₋ The location where the samples were taken

₋ Who collected, and who tested the samples

₋ Test Reports to be attached to the Report.

9. Explosions/Fire as included in the EMP

Check whether the following statement needs any updating:

‘Provision of firefighting equipment has been planned. This has to be verified prior to commissioning’

10. Equipment layout and installation, Noise and vibrations included in the EMP

Check whether the following statement needs any updating:

‘Disturbances have been kept to a minimum. No significant noise and vibration impacts recorded and no complaints.’

11. Transportation and storage of materials: Nuisance to the general public as included

in the EMP

It has been stated that:

“the contractor has failed to cover construction material at the grid substation site. Air borne dust emissions were observed during the site visit.”

It is advisable to provide proper guidance and directions for the contractor to mitigate this impact.

Subsequent monitoring is also needed.

12. Avian Collision as included in the EMP.

It has been stated that:

“Construction work of the transmission line is too early to consider the proposed activities”

It has to be noted that the stringing is now in progress. Therefore, bird collisions monitoring should be commenced without any further delay.

13. Check whether the Safeguard Monitoring is followed according to the EMoP

proposed in the EIA Report. Check the locations, frequency, parameters, etc.

14. EMoP – Monitoring Reports for Grid Sub-station

(i) Air Quality monitoring report conducted by the NBRO

Air Quality measurement report received for the period from July 01,2019 to September 30, 2019, For Grid Substation (GSS);

(Measured parameters are CO, PM10, PM2.5, Pb); TSPM has not been measured.

According to the report, data was measured on 18th & 19th Sep 2019, but the results table

63

in the same report depicts CO was measured on 10/04/2019 and analyzed on 10/04/2019 whereas PM 10, PM 2.S, Pb were measured on 09-10/04/2019 and analyzed on 12/04/2019. Therefore, these dates are contradicting.

(ii) Water Quality report not received

(iii) Noise measurement report received Noise report has been received. Noise measurement was taken on 19th Sep 2019 at four locations identified by the client. Vibration levels have not been measured.

(iv) Soil report received. Location 1: Inside GSS

Location 2: Outside GSS The sample was collected on 10/04/2019 but tested on 02/10/2019 according to the report. Samples have not been collected during July–September period. The report that has been sent is for a soil sample collected in April!

15. Add a section on Unanticipated Impacts

16. Add a short write-up on any deviations from the EMP, and the EMoP as suggested in

the EIA Report.

17. Add a section on any ‘Lessons Learnt.’

18. It is not clear how you have received any Environmental Reports from the Contractor.

It is suggested that the Contractors are advised to maintain environmental monitoring

records to comply with the procedures using a standard template.
