EXECUTIVE SUMMARY

The Transmission Line Project is part of the Greater Mekong Sub-region (GMS) Power Project that will be made possible through the financial assistance of the World Bank. This project will provide a reliable supply of electricity to Kampong Cham and Stung Treng Provinces.

Two 115kV double circuit transmission lines are to be constructed by Electricit6 Du Cambodge (EDC). One 115 kV transmission line will extend 66 km. within from the Vietnamese Border to Kampong Cham crossing Tbong Kmum District and Pohnea Kraek District running through 10 Communes primarily on the western/southern side of National Road (NR) No. 7. Substations on this line will be constructed in Kraek, Suong, and Kampong Cham. The other 115 kV transmission line will extend 56 km. passing through from the Laotian Border to Stung Treng crossing Stung Treng District and passing through one Commune as it runs along the west/south side of NR No. 7 with a substation in Strung Treng.

The settlement and land use pattern along the proposed route is primarily rural composed of villages of between 200-250 households with small areas of urban settlement. The local economy is characterized by rural production and provision of basic goods and services. The primary occupation among the Affected Persons (APs) is farming (38% of AP respondents) with rice as the main source of income. There are a total of 30 villages with a total of 7,851 households and a total population of 36,830.

To effectively evaluate potential impacts socioeconomic surveys have been conducted. The Korean Electric Power Corporation (KEPCO) has formulated a Resettlement Action Plan (RAP) for the relocation of households and other structures and land use restrictions within the Transmission Line Right of Way (ROW) and the four substations to identify impacts on the affected population and provide proper compensation. A detailed survey of the route will be carried out to finalize and peg the transmission line centerline, ROW, and tower locations to identify the people affected by construction and substation sites, and to inform APs what aspects and what extent of their physical and non-physical assets are affected. This expected to occur sometime in 2007.

The Consulting firm Social and Business Khmer Research and Development (SBK) has conducted socioeconomic surveys of Affected Persons at proposed Substation locations, as well as a Resettlement Cost Study to determine the costs of resettlement compensation as part of the RAP to ensure that the rates reflect accurate replacement costs for losses at current market value. These are independent and objective studies in the current Feasibility Study Phase of the Project to determine value of land, structures, perennial and annual crops, and other non-land based income (e.g., businesses, fishponds). This maximizes the economic and social benefits of the investment. These rates will be updated by a professional asset valuer during the Detailed Design Phase when final compensation rates acceptable to both APs and the Government.

The mitigation of impacts during construction will be based on selection of construction techniques and machinery that function with a minimum of ground disturbance. Construction activities on crop land will be timed to avoid the disturbance of field crops within one month of harvest wherever possible.

An ongoing process of information exchange through community participation of affected villagers and venders with agriculture specialists, contractors and builders, and officials of the Ministry of Agriculture, Forestry and Fishery facilitates the work of agencies and stakeholders involved and reduces potential conflicts, minimizes risks of project delays, and

Ministry of Industry, Mines and Energy vii Korea Electric Power Corporation Resettlement Plan Rural Electrification and Transmission Line Project enables a comprehensive development program design of resettlement and rehabilitation that prioritizes the needs of the affected villagers.

An Income Restoration Strategy has been developed if effects or losses on land, houses, structures, crops, trees, and communal properties cannot be avoided. APs will be compensated in cash or in kind at replacement cost to maintain or improve their livelihood and socioeconomic foundation. A crop value of US$ 200/t has been established as the cost estimate for rice, as well as a 5 year loss in productivity for trees. Severely affected farmers losing 20% or more of total productive landholding and vulnerable groups will be entitled to other rehabilitation assistance, including extension and technical assistance to improve productivity on remaining land or to develop alternative livelihoods.

Lack of formal legal rights to land does not prevent APs from receiving compensation and rehabilitation assistance. Those APs in possession of user's rights or any form of written or verbal agreements with Provincial, District, or Commune authorities to utilize the land are entitled to compensation and assistance. Tenants are also entitled to compensation and assistance. Rehabilitation assistance will be provided to those requiring relocation and to recover social and economic networks to pre-project levels or better. A Housing Relocation Allowance and Transportation Allowance will be provided to relocating APs to enable the transport of affected households' building materials and other affected properties to new sites. A cash payment of US$40 per house. A Cost of Disruption Allowance in the amount of US$40 will be paid to every relocating household and households severely affected by loss of 10% or more of productive, income-generating assets.

A Business Relocation Allowance will be provided for businesses required to close for relocation of US$40 if their businesses are not registered. The 94 affected shops will be compensated at full replacement cost depending on the type of structure without deduction for depreciation or salvageable materials for affected structures and other fixed assets. Disruption allowance during the relocation period will be provided at US$40 or the equivalent of 40kg of rice per household for businesses. Compensation for loss of business will be in accordance with the income loss for registered businesses. Employees are entitled to a cash compensation for lost wages while the business is reorganizing to its new site. Residential land acquisition (easement fee) without structures along the transmission line ROW will be compensated at 15% of replacement cost of residential land, and APs are entitled to use residential land for agricultural purposes.

Special Assistance for Socially or Economically Vulnerable Households such as the very poor, households headed by the aged, women, and the disabled, as well as ethnic minorities will be provided so they may improve their socio-economic conditions based on identified needs and priorities. This includes assistance for landless households to obtain land, assistance to the poor to improve their housing, as well as skills training to learn a trade.

Total estimated costs of implementation of the RP are US$ 538,382.13 including all entitlements, implementation, contingencies, and Incremental Administrative Costs. The incremental costs of administration related to the preparation and implementation of the RP including External Monitoring are estimated at 20% of the total resettlement cost or US$ 69,023.35. The total costs of compensation for the Project including a 30% contingency are estimated at US$469,358.78.

From project inception and as an ongoing process of the RP, monitoring and evaluation of Person's Affected by the Project (PAP's) will be carried out to insure that appropriate compensation is received, that community participation and grievance procedures are in accordance with a the RAP, and that restoration of public facilities and infrastructure is

1. PROJECT BACKGROUND

With financial support from World Bank, EDC has launched the construction project of two transmission lines from the Laotian Border to Stung Treng and from the Vietnamese Border to Kampong Cham. This project is a part of the Greater Mekong Sub-region (GMS) Power Project. As clearly defined by the Ministry of Environment the project is going to be carried out with taking into serious consideration the environmental sustainability of the affected areas along the Right of Way (ROW).

To effectively evaluate the impact of the project KEPCO has carried out an Initial Environmental Examination (IEE) in an attempt to identify the number of local residents affected by the project, the nature and degree of the impact on them, measures taken to minimize the effects and compensation, and other assistance to be delivered to affected people for unavoidable impacts.

The social impacts from the transmission lines will be the relocation of households and dwellings and other buildings within the ROW during construction, and land use restrictions within the ROW during operation.

The primary bio-physical impacts associated with transmission line construction and operations are land use change, vegetation loss, minor habitat loss, wildlife death, and minor erosion.

1.1. PURPOSE OF THE PROJECT

The purpose of this Resettlement Plan is to:

- Identify the design, construction, and maintenance measures to avoid or mitigate potential adverse impacts that will be taken into consideration for the final design of the project.

- Identify the people affected by both the construction of the transmission line and all substation sites as those who stand to lose all or part of their physical and non- physical assets, including homes, homesteads, productive lands, commercial properties, tenancy, income-earning opportunities, social and cultural activities and relationships, and other losses.

- Assist to develop their social and economic potential in order to improve or at least restore their incomes and living standards to pre-project level so as not to be worse off than they would have been without the project being undertaken.

1.2. LEGAL AND POLICY FRAMEWORK

There is no specific government policy relating to the details of resettlement and compensation in Cambodia other than the general requirements for compensation to be provided. A policy has been developed for the project taking into account relevant Cambodian and World Bank Laws and Policies.

1.2.1 Cambodian Relevant Laws Cambodian laws relating to resettlement and compensation are included in the constitution of Cambodia issued on September 24, 1993, Land Law, Electricity Law, Decrees and sub- decrees.

Ministry of Industry, Mines and Energy 1 Korea Electric Power Corporation Resettlement Plan Rural Electrification and Transmission Line Project

1.2.1 World Bank Operational Policy The World Bank requires that land acquisition and resettlement be minimized as much as possible, and compensation/resettlement be carried out so as to maintain or improve the standards of living of project-affected people.

World Bank policy in relation to resettlement and compensation are set out in Operational Policy (O.P.) 4.12: Involuntary Resettlement and are included later in this report.

2.2. SCOPE OF THE PROJECT

The followings is the scope and extent of the project:

* A 11 5kV double circuit transmission line from the Vietnamese Border containing the Kraek Substation, Suong Substation, and Kampong Chain Substation, 66 km of concrete poles.

* A 11 5kV double circuit transmission line from the Laotian Border to Stung Treng Substation, 56 km of steel lattice towers. To contain four substations, located in Kraek, Soung, Kompong Chain, and Stung Treng. Ministry of Industry, Mines and Energy 3 Korea Electric Power Corporation Resettlement Plan Rural Electrification and Transmission Line Project

* The tree clearance of a 30 m wide path along the transmission line route (15m on either side from the central line).

* The Resettlement of Affected Persons along the path of clearance of the power transmission line (6.5-8m on either side from the central power line).

* The land for three substations at Kampong Cham Province to be cleared with the dimensions of about 70m x 70m and one substation at Stung Treng to be cleared being about 50m x 70 m.

2.3. AMOUNT OF LAND REQUIRED FOR CONSTRUCTION

In general the project will require the following areas of land:

* 0.26 ha of land for pole footing based transmission line from the Vietnamese Border to Kampong Cham Province.

* 1.73 ha of land for tower footing based transmission line from the Laotian Border to Stung Treng Province.

* 2.1 ha of land for the four substations including the access roads for the four substations.

The construction of 115 kV transmission lines and substations will require the acquisition of land, or in the case of transmission lines, restriction of land use below the power lines. All substation sites have been identified. The four substations are located on private lands. Towers for the transmission lines include standard lattice towers for which an area of 25 m2 is required per tower. The number and location of towers were determined during the detailed design phase; however, land owners will lose only a small area for each tower.

There is not much agricultural land within the proposed alignments. When it is necessary to construct transmission lines across agricultural land the EdC will permanently acquire the land on which the tower is to be situated. In the unlikely event that it is necessary to acquire land for towers, compensation will be provided to the affected persons (APs) on whose land the tower(s) will be located.

2.4. TRANSMISSION LINE ROUTE

- Transmission line from the Vietnamese Border to Kampong Cham: It is a 66 km route running mainly on the southern side of National Road 7 (NR7) and parallel to the road in a direct line from Kampong Cham substation to the border. The route is generally set back 15 - 25 m from NR 7 to avoid houses near the roadside and minimize line length. There is a major change in direction at a cross line heading towards the border and then the route turns southeast and runs along the road 72.

- Transmission line from the Laos Border to Stung Treng: This route from the Laotian Border to Stung Treng is approximately 56 km and runs along the west side of NR7. It would be set back from the road by 15 - 25m in order to reduce environmental impact. Most trees and plants along the west side of the road have already been pruned so that the necessary conductor clearance distance will be provided. There are few settlements and individual houses along the route.

- From the Vietnamese Border to Kampong Cham The chosen nominal voltage level of the 115 kV corresponds to the intended voltage of the interconnection with Vietnam.

This transmission line would be essential to supply power to many customers; therefore it is necessary to determine if a double circuit transmission line need be constructed. A double circuit transmission line will be is under consideration i) to maintain N-1 level reliability in the case of the loss of one element of the power system so that the security of the system should not be compromised ii) to save 10% in construction costs iii) to avoid a forced outage (one - two months during construction) the installation of an additional circuit in the future which would affect many households, factories, and the public.

- From the Laos Border to Stung Treng The chosen nominal voltage level of the 115kV corresponds to the intended voltage of interconnection with Laos.

Although demand at Stung Treng may currently be low, The Ministry of Industry, Mines, and Energy (MIME) has emphasized the importance of Stung Treng as the hub in the northeast which is a focus area of a regional development triangle between Cambodia, Laos, and Vietnam. Therefore, double circuit transmission lines will be installed to satisfy the above reasons as those stated for Kompong Cham.

2.6. TREE CLEARANCE

Trees will be either removed or periodically pruned to provide necessary line clearance, whilst minor pruning will be required for insulated distribution lines. The SWER alignment will avoid palm trees (primarily sugar palms) in preference to trees grown for wood and smaller fruit trees as many of these trees can be pruned to provide the necessary line clearance without killing the trees. If the growing tip of palm is removed then the tree dies.

Vegetation clearance distances will be maintained by pruning regrowth every 1-2 years. Cuttings will be offered to the local resident if the pruned tree is privately owned, or offered to the community for communal trees. However, if cuttings are not required then the contractor will be responsible for their disposal. It is proposed that pruning contracts be awarded to local people to maintain line clearances.

In transmission line construction the conductor usually comprises 20% to 30% of the material and labor costs. The selection of conductors is critical since the wind and tension loads that the supporting structures must withstand are dependent on the size and type of conductors used. Structure heights are also largely dependent on the conductors selected since maximum sag of phase conductors under maximum ice or maximum temperature conditions is governed by certain

Ministry of Industry, Mines and Energy 10 Korea Electric Power Corporation Resettlement Plan Rural Electrification and Transmission Line Project physical, mechanical, and dimensional properties of the conductor. Even environmental effects such as radio noise and audible noise are heavily influenced by the conductors themselves.

2.9. Substation Design

Transmission lines connected to other country's substations will be operated under the voltage of 115 kV with double circuits. Three s
