E628 Volume 2 Yixing Pumped Storage Project Environmental Impact Assessment Report for the Project of Circuit II Transmission Line from the 5OOkV Pumped Storage Power Station to Yili Substation   Executive Summary This project, to be carried out by loan from the World Bank, is currently at the stage of engineering route-option on the map. Environmental impact assessment must be done for power transmission projects according to relevant Chinese environmental protection management laws and regulations. In accordance with Environmnental Assessment Policy (OP) 4.01 of the World Bank, power transmission projects belong to catalogue B which need not complete environmental impact assessment but corresponding environmental impact analysis. The content of the executive summary is listed as follows: 1. Description of the Project 2. Environmental background of the Project 3. Potential environmental impact 4. Suggested mitigating measures 5. Environmental management plan 6. Public participation 1 Description of the Proiect This Project (the Project) is proposed to be the transmission line from the 500kV Tong'guanshan Pumped Storage Power Plant to Yili Substation. Its route is all located within Xinjie Town and Yixing Municipal tree farm, Yixing Municipality, Jiangsu Province. This transmission line (the Line) will be 2 6.3km long and built by double circuit mounting on same tower. 2 Environmental background of the Project The Line is from the 500kV step-up station of Tong'guanshan Pumped Storage Power Plant to the 500kV Ylli Substation. Most section of the Line is located in mountainous area on the south of Yixing Municipality and elevation difference of 2   the terrain the line will go through is quite big. Elevations of the 500kV step-up station of Tong'guanshan Pumped Storage Power Station and the 500kV Yili Substation are separately 300m and 25m. Terrain along the line is generally downland (about 80%)and mountainous region (about 20%). The topography trends lower from south to north. Plants are composed of pinery mostly and some bamboo groves. No resident is required to relocate for the Project. Tower foundations will occupy an area of 0.27ha totally. And The Line crosses over neither any highway presently nor river, but the proposed Ning-Hang highway. There is no residential houses within 200m along the Line. And the Line is 2km away from Yixing Municipal TV station antenna (beyond protective area of the TV station). 3 Potential environmental impact (1) During construction period * Building of the line would produce construction dust and noises, resulting in short-term impact on surroundings. * Access roads of the line construction site will acquire some land where vegetation would be affected in short period and will recover when construction is over. * Due to downland and mountainous region along the line, attention should be paid to impact incurred by soil erosion during construction period on ecological environment. * The Line will go through manual wood yard. As confirmed by investigation of forestry section of Yixing Municipal Forestry-Agriculture-bywork Bureau, there is no plants and animals to be protected. 3  * In case the Line crosses proposed highways, manual wood yard and tea plantation, it should span the area directly as possible according to design requirement so as to reduce impact on ecological environment. * As counted preliminarily, there are total 45 tower foundations for the Line that occupy an area of 0.27ha approximately. The land to be taken up is wood land and has a just small area scattered. The land occupation would produce minor impact on ecological environment. (2) During operation period * Electric field and magnetic field produced outside the line corridor by operation of the Line meet recommended limits. Meanwhile, audible noise is less than 5OdB(A). There is no impact on residential houses incurred because even over 200m away the side lines does not stand any residential house. * The Line is 2km away from the Municipal TV Station beyond the protective area of the TV Station. Radio interference produced by the Line in operation will not affect any radio facility. * During operation of the Line, no impact will produce on highways and existing power lines the Line will intercross. * The Line goes through mountainous area generally. Its construction has been approved by local administration and has no impact on urban and township construction. 4 Suggested mitigating measures (1) During construction period * Part of the line is located in mountainous area and its route-option and positioning should avoid abrupt slopes, places apt to landslide, earth creep and gulch and other bad geological regions. Reasonable tower positions should be 4  selected for this part of the line so as to reduce cubic meters of earth and stone to be excavated, to decrease soil erosion and to mitigate impact incurred by construction of tower foundations on environment. * Historic relics should be handled according to the Antiquity Preservation Law of the People's Republic of China once they are discovered during construction of the line. Construction work should come to a halt in no time and it should be reported to local antiquity preservation department. Meanwhile, shielding measures should be adopted. * No resettlement is involved in construction of the line; however, construction of tower foundations will occupy land. Economic compensation should be made for acquired land strictly according to Land Management Law of People's Republic of China and relevant rules of the World Bank. * When the line goes through manual wood yard, it should be built according to design standards and so minimum woods would be cut. (2) During operation period * Self standing towers (without anchoring cables) are mostly used for transrnission line stringing. Double circuit mounting on same tower is also adopted so that minimum land would be occupied. *The line corridor has been designed to avoid dense residential area. Electric field, magnetic field and audible noise produced by the operational line have no impact on residents. * The Line has sufficient clear height when crossing proposed highway, which would not cause impact on highway traffic. * Strengthen education on electric power to residents near the line corridor so that they can farm safely under the line corridor. See mitigating measures in Table 1. 5  5. Environmental management plan The mitigating measures of the Line have been presented according to environmental analysis results. The environmental management plan has been prepared for construction and operation periods of the Project. Refer to Table 2 (Page 16) monitoring plan of the environmental management plan. 6. Public participation Local government, all administrations and the masses on the Project site supporting construction of the Project consider it beneficial to development of local industry and to enhancement of local living quality.

Introduction In order to support electric delivery from Three Gorges to east China and requirement of Yixing Pumped Storage Power Station to be connected with the system, Jiangsu Provincial Electric Power Company intends to use World Bank loan to construct the Line from the 500kV Tong'guanshan Pumped Storage Power Station to Yili Substation. This environmental impact assessment (EIA) report describes direct and potential environmental impact incurred by construction of this transmission line project (called "the Project" below). The report is composed of: (1) Introduction (2) Description of the Project (3) Environmental background of the Project (4) Environmental impact during construction period (5)Environmental impact during operation period (6) Scheme analysis (7)Environmental management plan and mitigating measures (8) Public participation 1.1 Necessity of construction of the Proiect The Project will make use of loan from the World Bank. Jiangsu power grid is the receiver end of east China power network to which Three Gorges transmit electric power. And purpose of construction of the Project is exactly to support electric delivery from Three Gorges to East of China and requirement of Yixing Pumped Storage Power Station to be connected with the system. The Project will play a part in peak regulation, making up low peak, systematic frequency adjustment and phase regulation. It will be quite beneficial to improving reliability of the power grid for supplying power. Therefore, it is necessary to accelerate construction of the Project. 8  1.2Basis of environmental impact assessment for the Proiect 1.2.1 The law and regulation system in China Since the promulgation of environmental protection law in 1989, China has developed a comprehensive environmental protection law system. There have established environmental protection organizations at state level, province level and municipality level with sufficient scale. The following Chinese regulations are the basis of environmental impact assessment (EIA) for the Project. (1) Environmental Protection Law of the People's Republic of China (2) Land Management Law of the People's Republic of China (3) Antiquity Preservation Law of the People's Republic of China (4) The 253 decree State Council, Management Regulations for Environmental Protection of Construction Project (5) The 18 decree (1997) SEPB, Management Method for Environmental Protection of Electro-magnetic Radiation (6) Document Huanfa[2001]17 SEPA, the Notice on Annunciation (the first) of Directory of Classified Management of Environmental Protection for Construction Projects (7) Document GJ324 (1993) SEPB, the notice on strengthening the management of environmental impact assessment for construction project funded by internationalfinancial institutions (8) SEPA HJ/T24-1998 Technical regulations on environmental impact assessment of electromagnetic radiation produced by 500kV ultrahigh voltage transmission and transfer power engineering 1.2.2 Relevant standards * Environmental noise GB3096-93 Standard of Environment Noise of Urban Area, class 2 [55dB (A) at daytime, 45 dB (A) at nighttime] for environmental noise * Electric field intensity limits In case the transmission line stands close to dwelling, the electric field limit of the undistorted electric field is 4kV/m at the height of 1.5m in the residential area, 9  which is deemed to be the recommended assessment standard for electric field. * Magnetic field intensity limits The limit O.1mT of International Radiant Protection Association for the public radiation in one day is used as the recommended assessment standard of magnetic induction intensity. * Radio interference GB 15707-1995 Radio Interference Limits of Aerial High-voltage AC Transmission Lines: allowable value of radio interference at 20m away from side transmission lines is 55dB( i- V/m) under the condition----it is sunny, frequency is 0.5MHz and relative humidity is not more than 80%. 1.2.3 Requirements for power transmission project by the World Bank The World Bank comments that power transmission project as one with provision of extensive environmental risk that depends on project scale and position. The incurred impacts are relevant to construction of the substation and risk of electro-magnetic field (EMF). Power transmission projects belong to catalogue B according to the World Bank Environmental Assessment Policy (OP) 4.01 for environmental assessment. The Project need not complete environmental impact assessment but some environmental analysis. 1.2.4 Design reports of the Proiect Engineering Programming Route-option Report of the 500kV Pumped Storage Power Station-Yili Substation Circuit II Line, Jiangsu Provincial Electric Power Design Institute, March 2000 1.2.5 Project commitment In accordance with relevant environmental protection rules of China and the World 10  Bank, on May 21, 2001 the Jiangsu Provincial Electric Power Company entrust State Power Corporation Environmental Protection Research Institute (SPEPRI) (holding class A environmental impact assessment certificate) to carry out EIA for the Project. The SPEPRI, a science research institute directly affiliated to State Power Corporation of China, has one after another undertake the EIA for many projects funded by Chinese government and international financial organization. Major power transmission line projects are: * East China (Jiangsu) 500kV Power Transmission Project funded by the World Bank * Environmental supervision and monitoring for the Environmental Management Plan of the East China (Jiangsu) 500kV Power Transmission Project * Power transmission project of Beijing urban grid reconstruction funded by the World Bank *Jiangsu Provincial 220kV and 11OkV Power Transmission Projects in the year of 2002 * Nanjing 1 lOkV Power Transmission Project * Zhenjiang llOkV Dashikou and Jingshan Power Transmission Project * Wuxi 1 lOkV Power Transmission Project * Nantong lOkV Power Transmission Project * Lianyungang 1 lOkV Maopingxian Power Transmission Project The Project has not gone into final survey phase of the routes yet. Through design information and site survey, we know physical and social background of places the Line may pass by and the living quality environment and have conducted public participation and background measurement of electric field, magnetic field and noise level. This EIA report for the Project has been prepared based on the said work.  2.Description of the Proiect The Line passes by Xinjie Town and the municipal tree farm, Yixing Municipality. Terrain along the line is generally downland and mountainous region; the former occupies about 80% and the latter about 20%. In figure 2-1 route layout of the 500kV Pumped Storage Power Station-Yili Substation circuit II line, we can see the Line route.Coming northward from the Storage Power Station, the line turns left and goes westward through Nanmen Mountain and Shanhua Mountain, spans programmed upper reservoir area of Storage Power Station Phase II; and then turns right, passes through Jinshanwu, crosses again upper reservoir area of Storage Power Station Phase II (the above route has an elevation of 252m) and reaches west of Zhupo Mountain; the line then spans northward proposed Ning-Hang highway and 220kV Yitao circuit I and II lines, gets to west of Minnan Village, Xinjie Town and goes into the Yili Substation. With a type of LGJ 4 X 400 the Line is 6.3km long and will be built by double circuit mounting on same tower. Number of towers: 45 Land area to be occupied by tower foundations: 0.27ha Refer to figure 2-1 route layout of the 500kV Pumped Storage Power Station-Yili Substation circuit II line. 12  3 Environmental background situation 3.1 Physical environment The route is located on south bank of Yangtze Delta and west of Taihu Lake drainage area. The whole line is within hilly region on south of Yixing and does not pass by rivers. Hilly region of south of Yixing stands on east of Yili low mountain hilly area. It is generally downland and mountain land along the Line and mountain land occupies about 80% in terms of the line's length. The line mainly crosses over Nanmen Mountain, Shanhua Mountain, Jingshanwu and Zhupo Mountain; their elevations are 436.5-70.0m. Downland about 20% spreads generally at north foot of Zhupo and Taohua Mountains and it has an elevation of approximately 70.0-25.0m. Topography along the line is complicated with obvious fluctuation. Terrain along the line is high and most section is not affected by flood in rainy seasons. However, due to high mountains and abrupt slopes along the line, runoff might gather fast in ditches and valleys when rainstorm falls continuously so that mountain torrents would happen at high speed. Towers should be set up far away torrent gulches. Refer to Figure 3-1(a) and Figure 3-1(b) physical background layout along the Line. Meteorological conditions of the Project are listed in Table 3-1 below. 13  Table 3-1 Meteorological conditions of the Project Meteorological elements Data Meteorological elements Data Average temperature of a few years ( ) 15.7 Average wind speed of a few years 3.0 mls Lowest average month temperature( ) -0.6 Corresponding prevailing wind SE direction Lowest temperature in extreme -13.1 Average of highest wind speeds of 13.8 condition( ) a few years m/s Highest average month temperature( ) 30.8 Corresponding prevailing wind SE direction Highest temperature in extreme 39.6 Highest wind speed of a few years 17.7 condition( ) m/s Average annual rainfall of a few years 1241.2 Corresponding prevailing wind SSW (mm) direction Highest annual rainfall (mm) 1738.4 Average evaporation capacity of 879.1 water surfaces of a few years mm Lowest annual rainfall (mm) 679.1 Highest annual evaporation 1223.3 capacity of water surfaces mm Average precipitation days of a few 133.4 Lowest annual evaporation 703.6 years (d) capacity of water surfaces mm Average fog days of a few years (d) 27.0 Frostfree period d 322.5 Average relative humidity of a few 80 years (%) 3.2 Social environment At north latitude of 31 07 -31 37 and east longitude of 119 31 -120 03',Yixing Municipality located in south of Jiangsu Province is center of the delta formed by Shanghai, Ningbo and Hangzhou, at the juncture of Jiangsu, Zhejiang and Anhui Provinces. As recorded in Yixing Municipal Statistical Yearbook of 2001, at the end of 1999 the whole municipality had an area of 2038.7km2 and a population of 1,082,400 with an average population density of 531 persons/km2. In 1999, the municipality gained 17.5 billion Yuan of GDP and 42.28 billion Yuan of total output value of industry and agriculture, of which total output value in industry was 39.26 billion Yuan and in farming, forestry and animal husbandry was 3.02 billion Yuan. 14  Yixing Municipal High-tech Garden of Environmental Protection involved in the Project, with programmed area of 38km2, had a population of 17394, GDP of 31.64 million Yuan, total industrial and agricultural output value of 71.4 million Yixing Municipality has 75773.3ha of cultivated land and 40000ha of wood land. And the High-tech Garden of Environmental Protection has 718. lha cultivated land and 170.5ha of wood land. There is no nature conservation area and natural habitat in the garden. 3.3 Ecological environment The area of Jiangsu Province has developed for more than 6000 years with cultivated land and manual river network. Nowadays selected substation sites mostly cover cultivated farm field. There is no primary forest, wetland and variety and species in inmminent danger. Area'the Line goes through is mountainous region and downland with flourish plants: mainly pines (massons pines, black pines and exotic pines), firs (cedar, slash pines and Chisong pine) and vegetations in tea plantations. There are some Mao bamboo woods, chestnut trees and teas scattered around the Line. As confirmed by investigation of forestry section of Yixing Municipal Forestry-Agriculture-bywork Bureau, there is no rare wildlife or creature belonging to national key protection in wood yard the Line goes through. 15  4 The environmental impact during construction period 4.1 Identification of environmental impact Identification of environmental impact during construction period of the Project is listed in Table 4-1 below. Table 4-1 Identification of environmental impact during construction period Order Item Environmental impact 1 Land occupation tower foundation occupation interim occupation for construction (see 4.2.5) 2 Mineral resources No impact (see 4.2.4) 3 Hydrological conditions and flood Not affected by flood generally (see 4.2.7) 4 Construction dust Short-term impact on ambient air around construction site (see 4.2.2) 5 Construction noise Short-term impact on constructors and acoustic environment (see 4.2.3) 6 Sanitary water during construction No impact (see 4.2.1) 7 Vegetation Vegetation damaged in occupied land; some trees cut under the route through low hills (see 4.3.1) 8 Wetland ecology No impact on wetland (see 4.3.3) 9 Scenic view Affected a little (see 4.5.3) 10 Highway Short-term (half a day) impact (see 4.4) 11 Influx of construction teams * no cultural conflict * to increase residential incomes (see 4.5.4) 12 Cultural relics No impact (see 4.5.1) 13 Scenery and places of interest No impact (see 4.5.2) 14 Resettlement No resettlement required (see 4.5.5) 15 Water and soil conservation Only a little of soil would be excavated during construction of tower foundations, with minor impact. Such impact will disappear when construction is finished. See 4.3 16 Post and telecom communication No impact on the communication wires due wires, power transmission lines and to a long distance away in design (see 4.4) radio apparatus 16  4.2 Impact on physical environment 4.2.1 Impact on waters Construction of tower foundations will be carried out in different areas along the Line. Nearly 40 persons will be involved living in residential houses nearby or temporary work shed. A little sanitary water would be produced. During construction of tower foundations, mixing concrete needs water and so attention should be paid to stopping turbid water from running off to affect water bodies around. The Project does not cross rivers and manual river net, the line does not span water bodies and its construction has no impact on waters. 4.2.2 Impact on environmental air During construction of tower foundation, little localized secondary fly dust caused by naked soil may affect residents nearby temporarily. Such impact will disappear when construction is completed. 4.2.3 Impact on acoustic environment During construction of tower foundations, noise mainly comes from construction machines and windlass for stringing. However, it has just minor impact at daytime. 4.2.4 Impact on geologic resources From collected information and the geologic prospecting report for tower foundations, there is no mine around, which would not affect exploration of mineral resources. 4.2.5 Impact on land function Land occupation of tower foundations will change the land function into industrial land. During construction of tower foundations, it is necessary to acquire some land temporarily, which would be cleared up. However, the acquired land will recover when construction is over. 17  4.3 Ecological environment The Line crosses over downland and mountainous land where trees are mainly composed of manually planted pine trees with bamboo woods and tea plantations scattered on some hillside and both sides of valleys. Hence, construction of the line corridor needs clearing plants around tower foundations. There is no aboriginal natural area or wild environment along the line. Construction of the Line need acquire some land at interim such as equipment transportation roads and walking paths etc.. All the occupied land will recover after construction. Tower foundations will take up an area of 0.27ha. As construction begins, the existing vegetations would be cleared up. A little of soil would be excavated temporarily during construction of tower foundations and will be filled again when construction is completed. High-low feet tower foundations and maintenance of naked soil should be applied according to actual situation so as to conserve water and soil. 4.4 Impact on social environment Construction of the Project does not cross highway and has no impact on highway traffic. A little localized dust would be incurred by construction of tower foundations and has no impact on surroundings generally. The Line does not intercross or be parallel with important lines of communication and so has no impact on communication facility. 18  4.5 Impact on living quality environment 4.5.1 Impact on cultural resource (1) Culture&education, sanitary and recreation locations There is no hospital, school, sanatorium or reaction location even over 200m away both sides of the Line; so there does not exist impact on culture&education, sanitary and recreation locations. (2) Impact on historic relics From collected information and as confirmed by local cultural relic authority, there are no cultural relics within the Project area. 4.5.2 Impact on scenic spots and places of interest There is no scenic spots or places of interest in the area involved in the Project. And so no impact could be produced on such spots. 4.5.3 Impact on scenic view in the Line area Construction of the Line would incur temporary impact on scenic view around. 4.5.4 Influx of labor force (1) Principal work of the Line's construction is undertaken by professional staff who have been trained on special technology usually from electric construction companies within Jiangsu Province territory. Due to specialty of their work, they cannot be replaced by locals. However, some local staff may be hired to take up foundation excavation, transportation of cubic meter of earth and stone, conveyance of building materials and road building and repair etc.. That can offer locals some temporary work opportunities. 19  (2) The mass of construction people will locally increase the consumption and demand of social commodities and services. (3) Demand of a great deal of building and constructing materials for the Project's building will promote development of local building material industry, initiate direct or indirect employment opportunities for the locals and forward the development of local economy and enhancement of living standard of local people. (4) For the construction team, its company has prepared stringent regulations and management methods. All staff must observe the regulations and will not affect social order much. 4.5.5 Land occupation and resettlement & rehabilitation (1) From initial statistic results of present progress of the Project, tower foundations of the line occupy 0.27ha. (2) The Project does not involve house relocation and so there is no issue associated with resettlement. (3) During construction period, some land would be acquired temporarily and should recover planting or afforestation when construction is completed. (4) In terms of land occupation and compensation, the project-constructing unit-Jiangsu Provincial Electric Power Company has trusted East China Reconnaissance Design Institute (ECRDI) with this task. This report explains the issue only in principle. Refer to the RAP for the Project by ECRDI about relevant details. (5) The ownership of land belongs to the state as prescribed in Chinese laws. Farmers etc. natural persons and enterprises just own right to use land. The state conducts uniform programming and management of land usage. For land requisition activity by the project-constructing unit, associated requisition procedures must be implemented stringently in compliance with Land 20  Management Law and other relevant laws of China. Existing land users will be compensated according to the above laws for their right of land use and for crops. 5 Potential environmental impact during operation period 5.1 Identification of environmental impact Identification of environmental impact during operation period is listed in Table 5-1. Table 5-1 Identification of environmental impact during operation period Order Item Environmental impact 1 Land occupation The Lines' permanent occupation, land function damaged, see 5.3.2 2 Electro-magnetic field Minor impact, see 5.2.4 3 Noise Certain impact on acoustic environment see 5.2.3 4 Wetland ecology No impact see 5.3.4 5 Vegetation Some vegetation would be cleared up by the tower foundations 6 Rare animal No impact, see 5.3.1 7 Highway Designed in compliance with Design Technical Code of Aerial Transmission Line etc., no impact see 5.4.1 8 Wire and radio communication No impact see 5.2.4 9 Cultural relics No impact see 5.4.5 10 Scenic view No impact see 5.4.6 11 Human health No impact see 5.4.4 12 Influx of operators no cultural conflict commercial income increased See 5.4.7 5.2 Impact on physical environment 5.2.1 Impact on waters The Line does not cross over rivers and so has no impact on waters. 21  5.2.2 Impact on environmental air Transmission lines during operation period have no impact on air environment. 5.2.3 Impact on acoustic environment Noise level of right-of-way abroad or at home is usually below 5OdB(A). The actual measurement results of audible noise for East China 500kV transmission lines (Renzhuang-Huaiying, Huaiying-Jiangdu, Jiangdu-Wunan, Doushan-Huangdu and Shipai-Shengpu) show: noise value under right-of-way is 40.2-48.8 dB(A); it is estimated that noise level under corridor of newly built transmission lines will be less than 5OdB(A) under normal power frequency. Noise cause by the Line will not affect residents because there is no residential houses within 200m away the Line. 5.2.4 Impact on radiation environment (1) Transmission lines * Electric field intensity and magnetic field intensity of the Project is separately 0.850-0.910V/m and 0.023 104_0.019 104mT, far less than recommended limits of 4kV/m and 0.1 mT. -From actual measurement results for transmission lines under operation, it can be estimated that electric field intensity within 40m wide belt area under the proposed 500kV transmission line (two circuits) corridor is between 3.802-7.807kV/m and high values occur below ingoing and outgoing line generally. By means of analog monitoring, it is estimated that electric field intensity within 40m wide belt area under the newly built 500kV transmission line (two circuits) corridor borders upon actual measurement results. The analog monitoring results shows: ground electric field intensities (at 1.5m high) outside the Line corridor in operation are almost less than the limit 4kV/m. Magnetic field intensity produced by operational 500kV transmission lines is 4.928 10-3 6.888 10-3mT, far less than recommended limit of O. lmT. It can be estimated that magnetic field produced by the Project will be far less than the recommended limit of O. lmT. (2) Radio interference 22  Based on collected relevant information and actual measurement results, radio interference level of 5OOkV transmission lines is known less than 44-46 dB( V/m), below standard limit of 55 dB V/m . It can be estimated that radio interference produced by the proposed 5OOkV Line will meet relevant standard. The Line, 2km away from television antenna of Yixing Municipal TV Station, is beyond protective area of the station without impact incurred on the station. 5.3 Imipact on ecological environment 5.3.1 Impact on rare birds There is no migration route of rare birds around the Line and so no impact on rare birds will be incurred by the Project. 5.3.2 ImDpact on ecology Tower foundations will occupy down land and mountainous area and some trees will be cut, which would damage vegetation around the foundations. High trees near the line corridor will be cut; the Line should be built strictly according to design requirements for sake of minimum trees to be cut. The line will be built up by double circuits and direct spanning. 5.3.3 Impact on ecological environment incurred by electric field and noise (1) Electric field will not affect growth of crops and other plants. (2) It has not been found that electric field is likely to bring any harmful influence to wilcl animals in their action or health. When the electric field intensity is up to 12kV/in, domestic animals' health and action are not affected at all. 23  (3) Operational electric field intensity of the Line will not have impact on bird activity. (4) All kinds of poultry or wild animals can live as usual under or near the transmission lines. Some research results show that audible noise of right-of-way have no impact on wild animal habitat. 5.3.4 Impact on ecological environment of wetland Tower foundations of the line does not occupy wetland without impact incurred on wetland 5.4 Impact on social environment 5.4.1 Impact on traffic incurred by transmission line operation The Line has been designed in accordance with Technical Regulation on Design of Aerial Transmission Lines, SDJ3-97 and other relevant technical specifications for aerial transmission lines intercrossing highways and rules concerned. The line intercrossing highways have sufficient headroom without impact on traffic. The line of the Project will cross over proposed Ning-Hang Highway and its potential impact on the highway has been taken into consideration in design. It can be estimated that operation of the Line will not affect traffic. 5.4.2 Intercrossed transmission lines'impact The Line has been designed in accordance with Technical Regulation on Design of Aerial Transmission Lines, SDJ3-97 and other relevant technical specifications and rules. This proposed 500kV transmission line, crossing over the 220kV Yitao circuit I and II, will increase towers' height. Therefore, the Line over the 220kV ones have no impact on them. 24  5.4.3 Impact on environmental sensitive areas There is no sensitive areas within 200m away the Line such as residential quarters, schools and hospitals etc.. It will not affect residents nearby. The Line is 2km away from the Municipal TV Station beyond the protective area of the Station. In design, the Line has been far away or passed by radio communication facilities, for which radio interference level incurred will meet recommended limit. 5.4.4 Impact on cultural resources, scenic spots and places of interest There are no schools, hospitals, cultural relics and scenic spots and places of interest even over 200m away the Line. Hence, no impact would be produced on them when the Line is in operation. 5.4.5 Impact on scenic views The Line has been designed to avoid resident gathering areas, towns and township programming area as far as possible. There will be no harmful impact on scenic views. 5.4.6 Iiiflux of labor force It is mainly professionally trained technicians that conduct routine operation when the Project is completed. Similar with influence of the labor influx during construction period, the operating personnel would not generate inflict with locals in employment and culture. 25  6 Scheme analysis 6.1 Impact with no newly built substations and power transmission lines (1) Jiangsu Province lacks of available water resources and has no much exploitable coal resources. Consequently, with the coal fired thermal power plant for main electric power supply, Jiangsu power grid needs to transport coal from other regions, which meanwhile increases pressure of environmental protection in the provincial area. The State Environmental Protection Administration performs total amount control of environmental capacity, for which it is quite difficult to set up another new electric power supply point on both sides of Yangtze River. (2) Tong'guanshan Pumped Storage Power Station is a project of environmental protection and energy conservation. Electric power supply is generally coal-fired power plants because there is no hydroelectric power plant and only a few oil-fired power plant within Jiangsu power grid. Due to single power supply structure of the power network, the units' function of peak regulation is weak, which causes peak regulation capacity of units in the whole province to be insufficient seriously. play a part in peak regulation, making up low peak, systematic frequency adjustment and phase regulation. In conclusion, it is quite necessary to construct the Project. 6.2 Schemes comparison The 500kV Storage Power Station-Yili Station circuit H line had four rout-option schemes: the recommended scheme, east scheme, mid scheme and west scheme. East scheme: the line comes northward from the Storage Power Station and turn right, passes by the upper reservoir area of programmed Storage Power Station Phase II, stretches down north edge of mountainous area being parallel with Ning-Hang Highway along and goes westward into Yili Substation. Mid scheme: the line comes northward from the Storage Power Station and turns left, passes through Shishi Nunnery relics and Dahanka, goes northwest along the 26  airline between the Storage Power Station and Yili Substation into the Substation finally. West scheme: the line comes northward from the Storage Power Station and turns left, goes westward through Shanhua Mountain from south and west of the mountain and passes by upper reservoir area of programmed Storage Power Station Phase II, crosses over Luohan Mountain and turn right, goes northward through Taohua Mountain till Yili Substation. Due to upper reservoir area of programmed Storage Power Station Phase II and its water level limit, mid scheme was eliminated. West scheme's total route and route through mountainous area are both long. This scheme has no obvious advantages and was not considered any more. The final selected scheme and east scheme have their own advantages. The recomnmlended scheme's advantage is its total route and route through mountainous area are both short and has minor impact on programmed Storage Power Station Phase II; while its disadvantage is construction and operation conditions are poor and it crosses over upper reservoir of the Storage Power Station several times. East scheme's advantage is route through mountainous area is short with obvious environmental protection advantage and good construction & operation conditions; while it has a disadvantage of bringing a certain impact on programmed Storage Power Station Phase II. However, these two schemes can meet requirements for building 500kV transmission lines. For sake of impact on construction of Storage Power Station Phase II, recomnumended scheme is adopted finally. 27  7 Environmental management plan and mitigating measures This report puts forward correspondingly environmental controlling and monitoring program and mitigating measures according to environmental impact produced by the substation. 7.1 During construction period (1) In design, some distance between transmission lines and residential quarters/sensitive areas has been taken into account, meeting relevant design regulations and environmental requirements, to ensure safety of residents around. (2) Stringing of transmission lines when crossing highways and rivers should shun traffic rush time; in design, headroom distance of conducting wires has been considered fully so as to ensure highway traffic safety and transmission line operation safety. Refer to Table 7-1 about mitigating measures of the substation (page 33). 7.2 During operation period (1) Promote propagation and education on electric equipment safety knowledge among the masses near the Line, and advise residents close to the substation of the way to do agricultural production safely. (2) Fix warning signs on tower foundations of the Line to advise residents not to stay under the line corridor for a long time or climb towers. Refer to Table 7-1 about mitigating measures of the substation (Page 33). 7.3 Land occupation and compensation Tower foundations would occupy certain amount of land. The mitigating and compensating measures to be made are as below: 28  (1) Construction sites and entry roads occupied by the tower foundations during construction period should be used as short and small (time----about half a year and area) as possible. Besides, corresponding economic crop outputs should be compensated when using the land as well as paying land rent. (2) The following actions should be taken for the land to be occupied permanently by the tower foundations: The project-constructing unit ought to give compensation according to area of occupied land-paying requisition compensation charge according to Land Management Law. 7.4 Resettlement and rehabilitation The Project does not involve resettlement but land occupation and so economic compensation should be made for acquired land according to Land Management Law. Refer to the Resettlement Action Plan (RAP) for the Project by ECRDI about relevant details. 7.5 Cliltural resources In case something is found by constructors during construction of the tower foundations, the site should be protected and construction work must be halted according to Chinese law. After the find is reported to local antiquity protection department, the department will make an assessment on it. Construction cannot be continued until the department grants permission. 7.6 Scenic views The Line trend, approved by local administration, avoids urban and township programming areas. Besides the Line is located in downland and mountainous region; tlierefore, it does not affect scenic views along the Line. 29  7.7 Protection of ecological environment (1) Access roads of the tower foundations would damage plants on the ground surface for a short term. The occupied land and production should recover in time in order to maintain ecological environment when construction is finished. (2) Design of the Line route should be optimized: under design conditions, towers of the line going over low hills should be designed strictly in compliance with design requirements and the Line should cross over the area as possible to minimize tree lop and keep ecologic environment balanced. JPEPC is responsible for this work. (3) High-low feet tower foundations and maintenance of naked soil should be applied according to actual situation so as to conserve water and soil. 7.8 Labor safety and protection Labor safety and protection of the Project during construction and operation periods will be carried out according to requirements of two rules-Interim Provisions On Occupational Safety and Health Supervision of Producibility Construction Engineering Projects (Labor Administration) and Interim Provisions of Implementing "Three Synchronousness" for Labor Safety and Industrial Health of Producibility Construction Engineering Projects (Energy Administration). This work will be in the charge of construction unit. 7.9 Monitoring management (1) During construction period Impact on ecological environment on the temporary occupied land will be monitored for construction of the substation. And the construction unit will be supervised for the purpose of occupying little cultivated field as possible and reverting ecological environment timely on the temporary occupied land. 30  (2) During operation period Environmental pollution should be monitored aperiodically along the Line. (3) Monitoring during construction period The assessment institute----State Power Environmental Protection Research Institute will monitor environmental impact during construction period of the Line. The major monitoring factors are construction fly dust and ecological environment. Construction dust will be monitored twice during construction period. Ecological environment will be monitored once during construction period. Monitoring methods: construction dust and ecological environment will be monitored generally by observation for assessment of damaged vegetation. Monitoring places: selected 5-10 tower foundations along the line. (4) Monitoring during operation period The assessment institute----State Power Environmental Protection Research Institute will monitor environmental impact during construction period of the Line. During operation period of the substation, the major monitoring factors are operational noise and electromagnetic field. Monitoring frequency: operation noise ----one time per year and electric field intensity and magnetic field intensity----one time per year. In case local residents complain, measurement should be made additionally. Monitoring methods: noise level is measured as required in relevant regulations of 31  Measuring Method of Environment Noise of Urban Area (GB/T14623-93) and Method of Measuring Noise at Boundary of Industrial Enterprises (GB 12349-90); and electromagnetic radiation is monitored according to the recommended method in Monitoring Apparatus and Method of Electromagnetic Radiation HJ/T1O.2-1996. Monitoring device: adopt noise, electric and magnetic field apparatuses in compliance with monitoring rules same as those ever used in monitoring for the East China (Jiangsu) 500kV Power Transmission Project----environmental noise is measured with a HS5670 integral sound level meter and electric field and magnetic field will be measured with an American Holaday 1H-3604 field intensity meter. Environmental monitoring in the Project will adopt apparatuses and equipment Detail cost is listed in Table 7-2 (page 34) 7.10 Mraining plan (1) During construction period Constructors' training on environmental protection and construction safety will be carried out by the construction unit and constructor company to enhance their consciousness of environmental protection. Constructors are educated by means of holding talks and paper publicity. The constructor company and Jiangsu Provincial Electric Power Company will be responsible for the training. (2) During operation period Operators' training on environmental protection and construction safety will be carried out. Environmental training's subject is mainly environmental protection and 32  safety----environmental impact assessment of transmission line projects and prevenitative and protective measures for electromagnetic radiation of transmission lines. The constructor company and Jiangsu Provincial Electric Power Company will be responisilble for the training. The Project has not begun yet and so detailed training schedule could not be decided inicluding training time, venue and staff. Jiangsu Provincial Electric Power Company has set up special environmental protection posts in Power Supply Bureaus of each city. Environmental protection speci; lists are assigned to these posts as full-time managers, responsible for actual environmental protection work of power supply Ullits.

ENIF and operational noise impact on Cl]'jrcl-nent cause by the 500kV subst,' ion was concerned much by the public ind 1 scussed ardently. Persons of relev;a' specifics made detail introduction of reicvw issues and dissolved worries of the - iblic. In response to problems put forward by the mass. coi;cerning professionals made a 39  detail explanation to residential representatives in terms of potential enviroiinental impact caused by power transmission construction. The acquired land must be compensated stringently according to relevant national regulations (including land occupation and young crops compensation). Electromagnetic field of the transmission lines in service was described in detail to the representati\es in addition to some respects to be cared about in future life and production. As long as residents keep far away the substation and transmission lines, electromagnetic field around them can meet the limit value. From investigation of the route, the 5OOkV Line is more than 200m away residential houses. The residential representatives thought that construction of the Project would not bring impact on them in terms of the Ling route. 8.2 Public participation investigation results Local government, all functional departments and the masses on the Projcct sites supporting construction of the Project consider it beneficial to development of local industry and traffic and to enhancement of local living quality; long-term and short-term occupied land should be compensated in accordance with Chinese standards. 40  Contents Executive Summary 1.
