BRIEF DESCRIPTION OF PROJECT:

Subjects of project:The construction of 220 kV Soc Trang substation is to meet the power load demand of SocTrang province which is forecasted to increase quickly on next years.Current situations:

* At present Soc Trang province receives electric power via 110 kV Tra Noc- Soc Trangand 110 kV Soc Trang -Bac Lieu transmission lines, they are poor transmission capacityand massive loss.

* Currently the load demands of Soc Trang Province are provided by 110/15 (22 kV) KV -2x40 MVA Soc Trang substation. In case of happening technical problems in Soc Trangsubstation, a large zone of Soc Trang town and nearby areas which are supplied by110kV substation would be failed of power.

Construction phaseSubstation Construction The station is located in a rice-field with elevationimpacts to: from 0.71m -1.42 m.- vegetation There are some cultivated mango and cocornut trees- dwelling zone (four trees) on ricefield patch in the construction area

X of the substation, they are scattered and adjacient tothe fence of expected operation house.The substation is far from dwelling zone, no house isaffected in the substation area.Impact occurs only to the paddy; therefore, impactson vegetation and dwelling zone are in signification.Since the substation area is a rice-field of flat low

Soil source for substation terrain ( 0.71- 1.42 m ), so the substation foundationembankment, X has to be filled to elevation of 2.22m. Espcially, sometransportation of soil for places has to be embanked to elevation of 2.82m. Sosubstation construction that earth work is accounted for great amount.and impacts due to Volume of earthworks including embankment andcorrosion and washout excavation is 101.692 m3.from soil works The embanked earth volume is 95503 m3 (

accounting for 94%).In Soc Trang Province, local authorities have alreadyassigned to five sand exploitation units on Hau riverin Ke Sach, Long Phu District and Cu Lao Dungisland to meet demand of local construction andleveling materials. Sand is exploited and gathered atspecified places in Soc Trang town in order to protectinvironment, and to be convinient for transportationand management.The expoited sand quantity is not only sufficient forlocal construction need of Soc Trang Province butalso for nearby districts.The filled earth volume is 95503 m3, It mainly issand to level ground to elevation of 2.22 m. Thatsand amount will be purchased from sandexploitation units allowed by local authorities.Sand for substation construction can be taken fromIgathering sand field at Ward 9 (Song Dinh) about3km from the substation, sand will be transported byboats along Kenh Thuy Loi (irregation canel) ortrucks depending on economic comparison ofcontractor.Earth will be filled into each layer with its thicknessof 20cm and then showered by water to obtain to

Foundation is paved by M100concrete layer with its thickness of 100.Talus of substation foundation is installed with acontrary filter layer with distance of 5m/layer as soonas commencement until to completion.With above constructing measures and shortconstruction time, filling quantity is greater thanexcavation quantity, moreover, stages ofinvestigation, design for the substation avoids areaswith importatnt drainage system in the region,therefore the construction of Soc Trang 220kVsubstation does not impact to Sedimentation and Soilerosion due to earth works.

Impact to surface water In substation area, water quality is good, does notquality. contaminate with salt and alum. Surveyed result and

digged on and positioned on the surface which wouldbe eroded when caught rain, sunshine or under wateror pumping water from foundation hole when waterin hole is alum water that will cause water problemand land around. The alum, erosion and sediment willbe stronger in rainy and flood days.According to investigation drilling results to depth of12m at substation and agricultural production inregion especially in dry season, alum phenomenon isa little and within limit. In dry season, the rice onpaddy still can grow and develope well. Therefore, itis very difficult to affect to water quality.There are two types of acid sulphate soils -ASS:

Acidify to adjacient land potential ASS and actual ASS. The potential ASS isand water soil containing a high content of pyrite (FeS2).

Normally this ASS is difficulty for developingplanted trees especially the rice. The actual ASS ispotential ASS which is exposed to the sun and water,creating high acid. Due to high acidity (low pH)high content of Fe, Al, low nutrients, actual ASS isnot suitable for cultivation for planted trees. ASSmay cause acidification of ground and surface waters.If potential ASS layer exists in foundation layer inthe construction area of subtation. When earth isexcavated, this may carry acid materials polluting toadjacent river, canal and pond. Water source will beaffected causing the risk and death of aquaticproducts in nearby rivers and canals due to low pHconcentration.However, in the substaition, excavation quantity issmaller than embankment of sand to average heightof 2.2 mActually substation site is paddy, it shows thatpotential ASS in substation area site does not exist onground. For underground, according to drillingresults, ASS is not massive enough to cause efffect tocultivated trees on ground, in addition, analysisresults of water sample at depth of l.Om in thesubstation reveals that cations such as Fe2++ Fe3+ donot exist, pH =8,0 is considerably high. Besides earthworks for construction of the substation is mostly forlelveling substation ground area and constructionscale occupies 51% substation area. Tlhereforeacidification will not occur or if occur, it will be atsmall level in during construction timeDuring construction time, if ASS is found,countermeasures such as powdered lime should becarried out immediately and until it satisfiesrequirements before discharging it. The contractorshould provide sufficiently powdered lime quantity

as required. Alum contaminated water should bechecked its pH level by machine or -colourcomparision papper. Excavated alum soil also can begathered at disposal areas to prevent effects to canals,pounds and paddy. Those soils can be ultilized atfoundation pits.

impact to river and Ihere are two canals of about 10 m in width and 1.5-drainage system 2m in depth about 50 far from the substation in the

north and the south.A small canal connecting 2 above large canals whichis arranged in the middle of the rice field will befilled for construction of the substation. The closureof this small canal doesn't impact to water supply anddrainage of the remaining paddy (see topographymap of substation site - appendix).The remaining paddy is irrigated and drained byexisting remaining canals.Since the substation is as above desbribed (about50m from the remaining canels) and above spokenconstruction measures preventing erosion andwashout are applied, therefore impacts to river anddrainage system are minor and difficult to happen.

Air pollution due to Operating machines, works of earth, mixing concreteemission of vehicle, and transporting materials cause air pollution mainlymachines and dusts during during construction time.construction time Air pollution mainly is dust from earth work, mixing

concrete and harmful gas (SO2, NOx, CO...) frommachinery emission to air in construction area.However, these impacts are in significant becauseearth work is not much, embanked earth is taken for aogreat amount.Soil will be filled into layers with thickness of 20 cm,and then showered and compacted well to obtain tocompression coefficient of 0.85 for substationfoundation and 0.98 for road foundation.

X Constructing time is 7 months (add time forinstalling: 11 months). Construction activities do nothappen simultanously; they are performed step bystep. Construction site is located on the paddy awayfrom residential area. Vehicles and machines arespecialied machine and checked and licensed to meetthe standard of air quality by competent authoritiesbefore for operating. During transportation, materials(sand, concrete...) must be covered carefully tominimize dust. Constructing at foundation pits andleveling earth do not cause a lot of dust because theexcavated earth is strong stick (sediment alluvial soil)Geological characteristics at substation site fromsurface to depth of 12m belongs to mixed river and

Noise due to operation of - Noise pollution during constructing can occur fromvehicle, machines during X materal transportation, construction and installationconstructing time equipments, activities of excavation and embankment

by machine, mixing cement.Some measures should be applied to prevent noisepollution as: Vehicles and machines which are used,should be checked and licensed before operating andchecked regularly and periodically in terms of airemission quality, noise level and horm.- Construction site is away residential areas and onthe paddy but vehicles should run in the daytime andworking hours and avoid working in the night time.- Machines shouldn't concentrate at the same time;

they should be continuous for each work.The construction time is considerably short (about 7months)Therefore impacts are in significant.

Soil, air and water Soil, air and water pollution caused by leakage of oilpollution due to leakage of from vehicles and construction equipments is due tooil, grease from the unmanaged replacement of machines at wrongconstruction vehicle and places or is from leakeage of oil and grease duringmachines operation.

However vehicles and machines are checked andlicensed and meet required standard beforeemploying, after that they should be checkedregularly.

X Since periodical vehicle washing and and lubricatingare carried out at garages. Therefore oil leakagealmost hardly occurs.However, this type of pollution can occur if themanagement is not effective. For example, it isallowable to employ vehicles which are not licensedfrom the Registration Authority, not maintainedregularly or leak oil, replacement of oil and grease iscarried out at wrong places and with unsuitableequipment ... Vehicles and machines do not check

and lubricate regularly and periodically and repairdoes not executed timely. New and used oil andgrease are under loose management and at unsuitableplaces.

Traffic disruption due to Before executing transportation activities,construction activities X transportation agencies have to discuss withnearby pubiic traffic road management units about related matters such as

transportation time (eg. transportation shall belimitted or stopped during rush hours in order toarchieve transporation safety and environmentprotection), transporter should comply with regulatedloads in transporation and covers with cavaspreventing dust and drop during transporatationprocess.Sand transportation road is traffic roads from sandgathering fields of ward 9 (Dinh river) namely LyThuong Kiet street, 30/4 and section of National roadIA crossing ward 9 and 10. In general, this roadsection is in good condition and low traffice density.Residental area along the road is scattered and lesspopulated than the town center, it is very difficult tooccur traffic distruption due to sand transportation oftrucks.Because the substation will be built on the paddytherefore it is necessary to construct a temporary roador use exist road of local or canal for materialtransportation. The construction of those roads couldlead to several social and invironmental impacts.However in F/s documents, which is used to analyze,did not show any details of expected temporary road.Detailed assessment of this matter has not performed.But based on map of location of the Soc Trangsubstation, volume of materials, implement time andworks at substation show that the above impacts areinsignificant.Because according to construction method,construction shall be devided into phases clearly,minimizing temporary occupied land, equipment andvehicles which are employed are specialized one andchecked carefully and in compliance with regulationson transportation safety and transportation. Whenheavy materials are transported, it is required todiscuss and gain approval of relative offices andarrange notice boardsThe road accessing the substation is paved byconcrete. With 170m length Distance from thesubstation to Nation Road IA. transportation distanceof electric equipments and alloy steel are short aselectric equipments : 209 m , alloy steel: 300 mThlerefore, the traffic disruption is neglegable

Impact to public health Because the project is located away from residentaland safety in construction X area and in a scattered region, therefore canips willcamps be arranged at substation site ground, it does not

affect to local people's houses. It is expected toarrange one material gathering field and store at areabetween foundation of standby transformer andcontrol building with total area of store and assessroad of 250 m2, local workers can be ultilized forsimple works, professional workers are estimated ofabout 65 people. According to standard (2m2 /people),housing area should be 100m2. Waste matters anddomestic sewage from camps will be collected bygeneral system of the town or treated at siteaccording to hygenie regulation. The number ofworkers (65 people) does not account for largequantity, construction activities are carried out inphases as mentioned in above part. Sanitzing worksof the camp should be signed with environmentalsanitary unit in ward 10 to collect waste matters.The health and safety for workers during constructingtime must be carried out in accordance withregulations. Construction units should have discusionwith relative local authorities about health and safetymeasures with before deployment.On construction site, workers should be devided intogroups according to their professional and livetogether as: iron team, concrete team, vehicle teamect. The leader of each team would manage anddirect the members in works and daily activities.

The each group implements their works one afterI another. The technical workers, the duty person ofsafety and health must attend regularly atconstruction site, to direct workers and to ensuresafety, health and epidemic prevention (as if),therefore, public health and labor safety fromconstruction process is minor.

Impacts to historical and X No relics of culture and history in area of the projectcultural monuments construction.

In the course of construction, in case of discoveringvaluable relics of culture and history, the contractorwill inform immediately to relative officers andmutually give a proper solution.110kV Soc Trang substation which is located in ward10 of Soc Trang province is about 5km far from ChuaDoi temple of ward 4 so that there is almost no effecton that temple.

Impacts to local peoples X The required land area for constructing project isdue to required land for 32.043 m2.constructing substation Construction area of the project is a paddy, houses of

IApriL2007 Pape 10

PECC2

local people does not affect since in course ofselecting substation location and routing thetransmission line, this location has been consideredand calculated both in ecomomic and suitabilityviewpoints in oder to avoid crossing local people'shouse and minimize land reclaimation. The selectedsubstation location is regarded suitable with currentand furture masterplan of local authorities.The land reclaimation of 32.043m2 for constructionof the substation just affect to six (06) households fortheir rice cultivated area. This household numberdoes not account for large quantity.The project affected households will be compensatedaccording to current regulations of state and localauthorities (such as Land Law, Decree No.197/2004/ND-CP of Government dated 03/12/2004on compensation, assistance and resettlement in caseof land reclaimation by state) and local people hadagreed with land reclaimation and compensationmethod (refer to Record of Public Consultation-Public consultation). Assistance alternatives for landacquisation are also executed for affected householdsin accordance with current regulations.Therefore, the impact to PAHs due to required land isnot much.

Operation phaseImpacts due to It is very difficult to occur environmentalsuperinfection of superinfection of electromagnetic field higher thanElectromagnetic field allowable standard for following reasons:(EMF) higher than When the project is designed, PECC2 have alreadyallowable standard. considered the magnetic intensity for 220kV

transmission line and substation and followed thedesign standard applied to magnetic field of highvoltage transmission line as regulated in VietnamPower sector Standard 11-TCN-21-84, 1l-TCN-19-84 and TCVN 2737-1995 ect.

Allowable level of EMF intensity at industrialX frequency per working and walking time in

electromagnetic affected area and allowable workingtime of one day and night depends on EMF tensity asfollows:

EMF1intensity

Soc Trang 220 kVSubstation - Environment Management Plan -EMPPECC2

which EMP intensity at industrial tensity is >5kV/m.However, distance from conductor to ground surfaceshould be > 12 m, in that distance, rated EMFintensity is low ( about 2.5 kV/m ).According to above calculation, electromagnetic fieldwill not affect to people's health.In addition, the substation is located far from theresidental area. Therefore EPM may not cause healthimpact on human

Interference with X There is not any interference with othercommunications lines communications, since substation location is not(Telephone, radio close to existing broastcasting and transmittingtelevision and other) stations, communication medium of local region.

The design follows safety standards of interferencewith radio, television and other communicationmedium

Effect to community's Effect to community's health and safety includinghealth and safety electrical shock is hardly to occur since dueincluding electrical shock attensions have been paid to safety measures andis hardly codes of electric power setor from design,

construction and operation. In addition, area nearbyX the substation is scattered and the substation has a

guard fence. Operators of the substation stricklyfollow safety regulations of high voltage transmissionline and are trained electrical safety operation.Safety and electric shock, fire and explosionprevention and protection aslo have been consideredand countermeasures have been introduced,prevention and protection works are checked andimplemented continuously and strictly.Howeve, public health and safety impacts includingrisk of electric shock can occur if these process andnorm of electric safety are violated.

Impacts to water quality Because substation location has already existed adue to domestic sewage of system of collecting domestic waste underproject operators management of a municipal environmental company

in Soc Trang town. Therefore the substationmanagement unit should sign a contract with thelocal environmental sanitary unit to collect the waste.In design of the substation, water supply and drainagesystems of substation operators aslso were desinged,

X water and solid waste treatment system also wasconsidered. It is proposed to take domesic water fromwater supply system of the town in group 3, ward 10(if it is available) or use drilled water which ispumped to filter tank via PVCD34 pipe to controlbuilding, guard house and rest house. After testing, ifwater does not meet domestic water standard.filtering and treatment system is required to satisfyrequirements of domestic water. According to testing

April/2007 Pape 1

+< Soc Trang 220 kV Substation - Environment Management Plan -EMP

PECC2

results of water sample in the expected substation

show that water quality in the substation- is quite

good( pH=8 ).Domestic sewage will be collected to a septic tank or

discharge to tank under to W.C and then connect to

general water drainage of the substation.Rain water flows along the slope of substation to the

collection pitch and then runs to general drainage

system of the substation.Sewage water of the substation will be treated before

draining to outside planned system of group 3.

Therefore, it is very difficult to happen effect towater quality due to sewage and waste matters of the

substation.

Air, water and soil During operation process, the substation will own

pollutions due to oil emmergency oil tanks, and it will be treated before

leakage (including PCBs) discharging to environment. Pressure transformer is

an oil immersed transformer, oil leakage does nothappen in normal operation regime.However, in case of oil failure, oil will be collected

to a seperation tank through cast or procelain pipe t'

200. Storage capacity of immergency oil tank should

X be adequate for containing oil volume of transformersinstalled at the substation. One pump will be equiped

at the immergency oil tank and operates

automatically when there is water in the tank, so that

the tank lways is in ready condition, pollution risk of

oil leakage is minorThe transformers do not use coolant with any fluid

containing PCBs, there is not any impact from this

substance.Noise pollution from Transformers which are used in the substation have

substation activities X noise level within permitted noise limit. With

substation, the noise mostly is from 50 HZ vibrationfrequency generating from pressure transformer.

However noise from this level load often is below

80dB, and this requirement have already noted intender document of equipment supply.The substation site is located far from dwelling area

with a distance of about 200m, so that effect is

insignificant.Explosive and fire Explosive and fire hazard can happen because of

cautions X cooling oil leakage or failure of transformer.However, that risk is minor. Since the substation is

operated according to specific regulations on

explosion and fire safety of substation as:Safety method when operating transformerSafety measures when contacting with electricequipmentSafety measures in managing, operating, repairing

regulations on substation.

Conflict between X Not happen because Substation site is isolated and

commissioning far from existing local dwelling area.

Staffs and local peoples The substation has fences and guard house to prevent

strangers and no duty peoples entering substationduring 24/24The commisioning staffs and workers work
