PROJECT IMPACTS ON ENVIRONMENT

The project does not cause big impact on physical environment ecological system.Impact on human life is also limited. To this project the environment issues arespecifically as follow:

THE IMPACTS ON PHYSICAL ENVIRONMENT

The kinds of impact on the physical environment examined here is the impacts of theproject on hydrosphere, atmosphere. and geosphere.

According to the properties and scope of the project which is described above, theproject has no impacts or inconsiderable impacts on physical environment forms.

The project docs not cause waste which have ability to pollute or contaminate waterquality (surface and underground water), air and ground quality around theconstruction. The construction in time of bein- constructed and put into operationdoes not change properties or value of land. water and air.

However, in the construction phase, the project can have affects on land formsmainly because of foundation construction. In addition, dust, noise and wastescreated in constructioni jobs can disturb to human and animal population around thesite. Vehicles can also destrov crops and trees.

IMPACTS ON BIOLOGY ENVIRONMENT AND ECOSYSTEM

According to Decree No.54/1999/ND-CP issued by GOV on the safety protection ofHV svstem, to 110 kV transmission line, the ROW is limited by 2 straight planes on2 sides of the line, parallel with the line. with distance to the external line when theline is quietly stay is 4 in. trees which are out of ROW must ensure so that whentrees fall, the distance from parts of the tree to conductor is 0.5 m and the straightdistance from conductor to top of the tree is not smaller than 3 m. Therefore, if thetree can grow and reach the conductor at the distance less than 3 m, then that tree hasto be cut down.

Tree-cutting will have impacts on biology resource and ecosystem.

However, the project is located in an exposed area with rice fields, and does not runacross forest or valuable natural resource. It does not also have impacts to anycritical llora and fauna. It does not cause erosion or loss of any exotic vegetables orhabitat.

IMPACTS ON HUMAN LIFE

Impacts on resideential area

Ihe impacts on residential areas, including status of PAPs. proposed solutions forcompensation and recovery for PAHs living have been described in details in theResettlement Action Plan (RAP). According to the baseline surveys, there are 4fully affected house and 4 partially affected house with total permanently acquiredland of 1041 m2. Hence it can be said that the impacts of the project on theresidential areas is small.

Impact of electromagneticfield on healthi of hItman and animals

According to the national criteria on limits of industrial-frequency electric fieldintensity and regulations on working environment regarding limits of electric fieldintensitv for people working in the affected areas. the permissive level of industrial-frequenicy electric field strength for people working or walking in the affected fieldin a days and night depends on electric field strength as given in Table 6.

Table 6:

Electric field strenoth <5 5 8 10 12 15 18 20 20<E<25 >25(kV/m)

The permissive Not 8 4 3 2 1 .8 .5 1/6 0working time in a day limitedand night (h)

Thus, the affected area of electric field is the space in whlich the industrial-frequencyelectric field strength larger than 5 kV/m. I-lowever, in the typical design used, thedistance from conductors to the ground shall be bigger than 7 m ( in high densityarea) or 6m (in low density area). At these distancse. the electric field strength isvery low in the level of around 2.5 kV/m. Therefore. for the residents who live underthe line route, electric field will not affect on their health.

Impacts on comminication projects anrd aircraft hazartds

There is no wireless communicating constructions near the line route. The projecttransmission connections will cause no aircraft hazards.

Impacts on thte lan(dscape, historic relic zone, temples, pagodas

The substation and associated transmission line connection are located in a suburbanarea. So the project site has been selected and designed with special attention toavoid impacts oin the existing landscape, military region. airport. historic relic.temple, pagodas. Therefore, the selected sites as agreed with the local authority hasno impacts on these sites.

Impacts fromn thte bombs mines remainiedfront thieformer wars

The substation and the ROW of transmission line connections are located in the areafree from the former wars' objects such as: bombs, mines. etc.

Project: South Saigon 220kV Substation and Associated 220-llOkV TL Connections /Page 18


Impactsfromfire or explosion

Explosivc substances will not be uscd in construction. There will be only excavation.There could be harzard of fire caused by cooking during construction period. Thisfact should be taken into consideration.

Impacts of noise, vibration, pollutionl

In the constructing phase, machine and vehicle operations could cause noise.vibration and dusts. In the operating phase, the noise of coronla charge for the 220kV and 110 kV line is neglectable.

Impacts on safety and health of workers

The safety methods in working for constructing workers as well as operatingworkers must be strictly applied according to the laws on safety for workingenvironment of Vietnam. The constractors and operaters should follow safetyprocedures to protect lifes and health of during different stages of construction suchas:

* Disarm of explosives before construction (if required)

* Safety requirements for transporting of equipment and materials

* Safety measures during excavation and erecting steel tower foundation

* During erection of pole and insulators installation.

* During conductor installing. stringing, sag taking and other accessoriesinstallation.

Besides, in the process of construction. the methods of hygiene and health servicemust be considered in order to prevent and treat diseases such as: malaria, typhoid.diarrhea... To have positive measure in order to reduce impacts on the health ofworkers.

CHAPTER 6: MITIGATION MEASURES

Mitigation measures for negative impacts of project will carry out on the selection ofsubstation location and line route and happen in 3 phases: design, construction and operation.

IN THE DESIGN PHASE

In the design phase. the selected alternative must guarantee the eco-technology of the project.and consider the project's inmpacts on environmnent and search for the methiods to reduce, limitthe negative impacts, particularly is:

a. With the ecosystem

With trees which are in the ROW. that means trees can affect the line route, must be cutdown. According to forest-protecting law of Vietnam, tree-cutting can affect the environmentis strictly controlled. Therefore the chosen of position for substation and T/L connections istried to avoid going through bushy forest. The selected substation and associated T/Lconnections are located in rice fields and lotus and fish ponds. so tree cutting cansubstantially avoided.

The substation are located in exposcd area, within its fence. Underneath the transformerlocation, it is arranged a concrete oil pit, large enough to absorb complete content oftransformer oil in the case of spillage.

The transformer shall be isolated and cooled by oil without PCBs.

b. With the residential area and with safety issues

The process of chosen the substation's location and drawing the line route is considered andcalculated in a best way in order to avoid peoplc's houscs. For the line that compels to runthrough resident area, the route has been selected to avoid cutting houses by turning the linesso that minimumn impacts on houses was achieved.

The technical solutions was selected in design to ensure minimum impacts on houses,constructions as well as safely to local residents and workers as described below:

Conductor: cross-section of conductor is chosen by economic current density is 1, lA/mm2

and calculated based on limited pressure regime with air temperature and highest internalloading capacity (wind).

Insulators: is chosen according to current regulations. The area which is passed by the lineroute is far from sea, not to go through dusty and poison-gas area. Therefore the impacts onatmosphere pollution with insulator is calculated at low-polluted level ([EC standards).Insulator of substation and line route is used with porcelain or tempered-glass insulator.Accessories is chosen to fit the size of conductor, insulator and to ensure the safe factoraccording to regulation.

Earthing. the substation and line route is earthed according to branch's procedures to ensurefor safe operation as well as people at residential area.

Pole, Ibundation.:

* TUse galvanized steel tower on the whole of line routes.

* Use reinforced concrete foundation on the spot.

The calculation and selection of solutions of line structure is based on climate condition inthe current electric-equipped procedure TCN- 19-84.

In design calculation, if the conductor arrangement on the poles which have the distance fromconductor to the ground is calculated 12m for lowest and the other safety distance are carried



out pursuant the norm, the electric strength under conductor from heart of the line out has themuch smaller value compared with the standard of WIO and norm promulgated by thebranch is < 5 kV/m. Therefore, worker can work under the line route normally.

c. With the telecommunitication projects and otter constructionts

The line route is designcd to go far from important wireless communicating constructionstherefore the problem of interference and dangerous impactss on the communicating line isnot considered.

Along the selected line route. by practical investigation. there is no area of historic, culturalrelic, not going through military zone. temple. pagodas, airports and not cause impacts onarea landscape, corresponds strategy of reducing impacts of the project on the environment.

d. With the area affected bJy thieformer wars:

In the site selection for the substation's and routes of T/L connections, one of highetstconcern is the former wvar consequences such as: bombs, mines, elc. which could be in theROW and in substation location. Hlowever, for this project. according to the exitingconditions, this possibility is not considerable and can be neglected.

IN THE CONSTRUCTION STAGE

In the process of construction. the mitigationi strategies are proposed as below:

Alethods of constructing management

2.2.1. C'onstructioni. . IArr/7ge't1enJt:

Rational arrangement. appropriate time schedule for implementing projectcomponents and the line sections would minimize temporary requisition of land.

Construction activities such as tree cutting, site clearance, foundation excavation.material transportation; tower erection, wire tensioning. etc. would have certain impactson the environment. Therefore, concrete mitigation measures proposed are:

Tree cuttin<g. rouite clearance

Apply measures of soil filling, tree and grass planting after construction, minimize theimpact of tree cutting to mitigate future impacts. For land supposed to erosion, maintaintrees with the allowable height in the ROW after cutting high trees to keep soil.

C'onstrzuction of acccss roads

Access roads for construction have been considered in the designl stage and specifiedbefore commencement. The main mitigation measures are:

Access road would originate from existing roads: main transportation roads (and asclose to the nearest line as possible.

Grade roads to retard erosion: compensate for lost farm production, industrial trees.and land used temporarily or permanentlv for the lie operations.

All of temporary roads for construction w-ill be destroyed when the project iscompleted and carried out recovery methods such as lcecliii . grass growing, and treegrowving. etc.

Sqt/e4 7eacsures:

Safety measures for construction must fully respect the safety regulations and procedures:

Project: South Saigon 220kV Substation and Associated 220-110kV T/L Connections iPage 21


+ Use specialized machines for transportation of tools, materials or heavy equipments.Check the machines before use. Ligament must be strong. Respect all regulations ontransportation safety.

+ Foundation cxcavation must comply all safety measures. Since the tower foundationsare small. there would not be much excavation. Foundation works would be carried outmainly by manual methods. The maximum unused soil volume of < Im3 as a result ofexcavation, would be left in the surrounding areas as agreed with the local authorities.

Any water pipes, underground sewers, communication or power cables found duringexcavation must be reported to the concerned agency. Strictly follow instructions of theagency.

+ Apply safety measures for tower erection, arm and insulator installation, wire worksand installation of other fittings.

Workers must respect the regulations on works, safety. labor protection and concentrateon their works. They will be given training on their jobs anid safety procedures.

Besides, conductor tensioning and tower transportation would be carried out right afterharvest of the annual crops to minimize the impact on crops in the ROW.

Constructioni camps

During construction. the works will be carried out mainly in open fields so workers camps-will be located close to villages for the convenient of food, drinking water andcommunications. However, workers should not allowed to live together with local residentsto avoid interfering their lifes.

Health care and protection for workers during project construction will strictly follow healthand sanitary regulations. Each construction team group will have a medical specialist to takecare of health service and to prevent and cure common and infection diseases.

Safetyfromfire, explosive

The construction method of line route and substation does not use explosives but manualexcavation. There should be regulations to contractors on cookings by construction workersto prevent fire.

Pollution caused bY noise, vibrationt, duist an^d wastes

During process of construction, there could be noise, vibration. polution because of dusts andwastes. To avoid these impacts. the following measure are applied:

- Since the constructioni is not very far from villages, working time for machiniery, vehicles should belimited during day time and normal working hours. Night slhift will he avoided.

- The machinle and vehicles for construction) anid transportation should lhave acceptable level of noiseand vibration. The requirements will be incorporated into bidding specification for selectionof contractors.

- To minimize impacts of wastes. construction wastes and wastes caused by workers' campswill be disposed in proper areas. acceptable by local communities. Waste from constructionand camp should not be discharged into water but should be treated before drainineT out;

- To reduce pollution by dusts. the construction site will be watered. Trucks withconstruction materials or wastes will be covered. Prefabricated mixture concrete will bepreferred if possible.

Project: South Saigon 220kV Substation and Associated 220-11 OkV TIL Connections (Page 22


DURING OPERATION

Management, operation, repair, and maintenance of the project.

The operation and maintenance of the project after commissioning will be carried out bv thePower Transmission Company No.4. The main works include operation, regularmaintenance and repair.

During the operation stages the following impacts could be on project environment: noisecaused by operating equipment, pollution caused by fuels or lubricants spillagc, elcctricitycutting and fires.

To reduce the above negative impacts, the following measures should be applied:

- Use equipment with permitted noise and vibration level;

- Build pit to treat leaking fuel or lubricants before draining out. There should be proceduresand regulations for collecting and disposing oil leakage at substation

- Maintain fence for safety; install warning signs to avoid electricity hazards to operators andlocal residents. During operation and imainitenianice, operator mnust obey strictly andsufficiently regulations of safety methods for management. operation, repair of high and lowvoltage lines and equipment. There must be task-ticket regime, operation ticket andpermissive procedures according to regulations. Operation should strictly follow the specificregulations of main safety methods as belowv:

Safety methods wvhen working at substation.

Safety methods wlhile touching electrical equipment.

Safety methods while taking the work of management. operation. repair the high.low voltage line route.

MVanagement of latd, trees tl7at violate thte ROW

PTC4 will have to inspect. to control land under the ROW belongs to substation and lineconnection area in order to timely find out violations of houses. trees.

Cutting trees wvhich violate the ROW is carried out aftcr informing owner organizations, localauthorities. and individuals at least 10 days. PTC4 has to cut trees. branches out from ROWand areas belonged to the substation. The owners of trees will supervise tree-cutting and theuse of trees and braches which are cut. The abuse of power network safety regulations onoperation and clerance of ROW to cut trees unruly is strictly prohibited.



CHAPTER 7: ANALYSIS OF ALTERNATIVES

During selection of line route and substation location. PECC2 engineers had carefully studieddifferent alternatives on map and at site and then carried out thorough investigation. Twoalternatives were considered for comparison.

Criteria for selection of substation sites and line connection route are:

- Closeness to load center:

- Convenience to connect the substation to the existing network:,

- Lowest impacts on environment and local people:

- In accordance with local planning and landscape.

Regarding the environment impacts. two alternatives are not different significantly.

So, the selected alternative is optimum not only in term of technical but also in term ofenvironment.

CHAPTER 8: DISPOSAL OF POLYCHLORINATED BIPHENYLS (PCB's)

This project is a new one.

Now aday. the power sector finished using PCBWs in electrical equipment.

Therefore, the disposal of PCB's is not a problenm for this project.

CHAPTER 9: PUBLIC PARTICIPATION AND DISCLOSUTRE

World Bank (the Bank) policy regarding community involvement provided in detailin the WB Environmental Assessment Source Book. Vol. 1 (1991). It is summarized asfollows.

Bank policy directs the borrower to publicly solicit, hear and considcr the concerns ofthe local community. other affected groups and local NGOs (non-governmentalorganizations) and to fully incorporate into the design and implementation of the project andthe Environmental Assessment (EA). The rationale for consideration and incorporation of theconcerns affected parties is to assure community acceptance and enhance the viability of theproject. The Bank has found that where such views have been successfully incorporated intothe design and plan of implementation, the projects are more likely to be successful. TheBank has not found community participation to be an impediment to proj ect execution. Onthe contrary. projects in which affected parties views have been excluded are more likely tosuffer from delay and issues resulting from community resistance.

Vietnam is a socialist country. The State is determined by the fundamental principle "ofpeople, ftont people and for people". The democratic approach to the social management ofGOY is expressed in the basic principle of principle 'people knoii', people dliscuss anc peoplecontr ol" all activities of the Government.

To avoid negative impacts on project affected people. Governmental Decree N175/CP issued on 1S April 1994 requires that all projects in the development of industry:energy. transport, water resource, agriculture, etc. should conduct a compliant EIA studymeeting the requirements of the environmental management authorities and the contents oflIA reports include predicted impacts and mitigation measures mutst be discussed with the

PAP.

The PAP should submit their comments and concerns to the project proponentsh.hio '-.1 their authorized representatives. e.g. governmental agencies (the people Committee.

People Council) and/or socio-political organizations (Fatherland Front, Farmers Association,Women UJnion etc.) or non-governmental organizations (e.g. Vietnam Association for theConservation of the Nature and Environment. Biological Association. Economic Association.Foresters Association etc.). These organizations should collect all comments from the localpeople and send them to the environmental management authorities (DOS'TE at provinciallevel or MOSTE at central level) or even to provincial People's Council or NationalAssembly. During the environmental review process. all comments and requirements of thePAP should be discussed and conclusions reported to the project proponents. so that theproject can develop proper alternatives and implement measures for mitigation of thenegative impacts. The, project will receive an investment license. only after appropriatemodification of location, design, capacity and/or teclnology of the project to meet therequirement of environmental protection and resettlement.

Involving affected people, especially the poor. often requires additional expenditures.The costs include travel and subsistence for attendance at meetings. Translation and expertadvice that the community needs to help to formulate a response to the proposal. etc. Suchcosts should be systematically budgeted. The EA team must ensure that issues raised inaffected communities are communicated to the other participants in the EA process. includingvarious public agencies and NGOs that may be in the larger process pf public consultation.

As the I.A proceeds, the people in the affected area should be kept informed routinelyand systematically. Written material must be translated into local languages. Where many areunable to read, oral discussion and visual presentations sessions (often. by the resident social

Monitoring, supervising the carrying out of mitigation of the environmentimpacts during the process of construction and operation of the project.

* Managing and checking health status of construction and operation workersand inhabitants.

* Managing and checking plants and animals under or neighboring the lineswhich may be affected by the lines.

The PTC4 during the project operation, has following responsibilities:

* Carrying out the regimes of checking and controlling periodically andsuddenly the operation status of the power network, especially atier raining,storming in order to have reasonable treatment measures. ensuring for goodoperation of the network. The checking and controlling also help finding andpreventing the construction of other works xwhich located in the line's corridorand violate the electrical safety regulations and ensure health and life ofinhabitants.

* Monitoring, recording break-downs, accidents caused annually by thenetwork. Considering abnormal weather and climate changes bv relevantareas. Thereby, having prevention and overcoming measures suitably, in timeand to restrain negative inpacts to environmient.

* Guiding. supervising agencies. localities, individualities to carry out correctlythe government's regulations on safety and protection of the power network.Simultaneously, suspending violating behaviors, requiring the formercondition restoration of the network. carrying out measures to stop violatingbehaviors and having necessary procedures to submit to the authorities forpenalty.

For the transnmission network, the contlens of periodical checking include:

* Checking conductors. grounding wires whether they are scratch or break.

* Checking insulators whether they are crack or break.

* Checking pole foundation for landslide or violated.

* Checking poles whether missed parts (due to be stolen), physical formchanged (due to clash) or corroded (due to weather, chemicals).

* Checking for invasion, invalid housing construction in the line's corridor.

* Checking for planting growth in the line's corridor, carrying out to cut off ifnecessary.

After checking. it must to set up reports and recommend for process measurcs (ifhaving).

4. IMPLEMENTATION PLAN AND FINANCIAL ESTIMATE

Implemenitation plan:

The mitigation of the environmental impacts by the project will be carried out fromthe beginning of the project establishment. In the primary design, this business hasbeen done by the consulting company with examined and approved by the investorbased on the Process and Norm by Electricity Sector and the environmentalregulations. During the construction period, this will be obeyed by the constructionunit, together with the supervision of the relevant authorities. During the operationperiod, the mitigation of the environmental impacts will be charged by specializedagencies.

The supervision and controlling will be frequently implemented during the projectprogress since design phase to operation phase. The supervision is based on thepresent mechanism.

It is better to be trained before the project implementation. However, as pointedabove, the training is not only to serve privately for this project, but also for allprojects in the areas where thev will manage. thus. if it is impossible to train soon,the training after that is not also useless.
