The Project is currently at the stage of engineering site-option (to substations) and route-option on the map (to transmission lines). Environmental impact assessment must be done for power transmission projects according to relevant Chinese environmental protection management laws and regulations for construction projects. In accordance with Environmental 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 original version of this report was delivered to the World Bank on May 30, 2002. On June 20, 2002, Mr. Baratz, principal expert of environmental protection from the World Bank, reviewed the report and provided comments. The following is updated content modified in accordance with the comments. The content of the executive summary is listed as follows: 1. Description of the Project 2.

Till end of 2001, it had owned 26 of 500kV transmission lines with the length of 3207km (including inter-provincial connection lines); 10 of 500kV substations (including switching stations) and 12 sets of transformers, with the capacity of 8000MVA. Currently, 220kV power grid is still main network in Jiangsu Province. The whole network has 142 of 220kV substations with 231 sets of step-down transformers and the transferred capacity of 29549MVA and 319 of 220kV transmission lines 8062.6km long totally (including inter-provincial connection lines). In order to improve the 500 kV network structure in Jiangsu Province, to meet the demand of growth in power consumption and social economy, to lower the cost of power transmission, to enhance the reliability of transmission in the power network, Jiangsu Province will necessarily construct the Project. The Project includes two proposed 500kV substations, one 500kV substation to be expanded, a transferred capacity of 2500MVA to be increased and 102km of 500kV transmission lines to be built. The new lines are composed of two sections----2xlkm Tianwan Power Station-Shanghe Substation line cut into the 500kV Lianyungang Substation and 2xSOkm of the 500kV Longtan - 500kV Dongshanqiao substations; they will be built by double circuit mounting on same tower. The expansion 500kV Yancheng Substation is to add another one main transformer, which would not cause any problem of ingoing and outgoing lines. One proposed substation is located in Xiabutou, Dongliu Village and Yuanjiabian Village, Qilin Town, Jiangning County, Nanjing Municipal. The other proposed substation, in Hexingzhuang of Yuchan Village, Yilu - 7 -  EIA report for the extension Project of East China (Jiangsu) 5OOkV Power Transmission Project Township, Guanyun County, Lianyungang Municipal, lies at the farm field juncture of Beiwei Group, Hexing Village and Datangwei Village. And the expansion substation is in Tangchen Village, Guomeng Township, Yandu County, Yancheng Municipal. 2 Environmental background of the Proiect The proposed 500kV substations, at the engineering site-option stage currently, are open and wide around from site investigation, will not cause resident relocation but farmland occupation and no dwelling stands within 150m away the substations' boundaries. The substation to be expanded does not need to acquire land. Through Jiangning and Xixia districts of Nanjing Municipal, Jiangsu Province, the 500kV transmission line between Dongshanqiao and Longtan substations goes over rolling low downy (ground elevation: 13.00-120.00m) with low hills and cols as well as even and relatively low-lying terrain (usual ground elevation: 6.90-13.00). There are dwellers along the line and they should be relocated. Tower foundations will occupy farmland. The following high-grade highways will be crossed by the line: Nanjing airport highway, Ning-Hang highway, Ning-Hu highway, National Highway number 104, Nanjing second ring road and third ring road. It will also cross two navigable rivers----Qinhuai River and Jiuxiang River. With farmland along, the 500kV transmission line Tianwan Power Station-Shanghe Substation line cut into the 500kV Lianyungang Substation passes through Datangwei, Xiaotangwei and Pengzhuang Village, Yilu Township, Guanyun County, Lianyungang Municipal. No houses, highways or rivers will be relocated or crossed over. Nanjing area and Lianyungang area to be passed through by the new lines are separately developed and underdeveloped economically. - 8 -  EIA report for the extension Project of East China (Jiangsu) 500kV Power Transmission Project 3 Potential environmental impact (1) During construction period Access road during construction period will take up some farmland temporarily causing short-term impact on crop planting. Planting will recover when construction is over. The Project sites are on the farmland. Building of the Project will have to clear all the crops in the land and occupy the land permanently. This will cause certain loss in agricultural production. Some farmland will be acquired temporarily for the Project during construction period, which would influence crop planting for a short term. However, crop planting will recover when construction work is finished. Building of the Project would produce construction dust and noises, resulting in short-term impact on surroundings. In case the transmission line crosses highways, railways, rivers and existing power lines, attention should be paid to impact incurred by the line on transportation traffic and the power lines' safe operation. (2) During operation period To the substations: PCBs are no longer used in compliance with Chinese rules and there will be no any impact incurred by PCBs on the environment. The Project's involving farmland would affect agricultural production, leading to annual decrease of 198.9t/a in local grain output. The Project will occupy total land of 17.33 ha. No house is required to remove but economic compensation and land reallocation should be done -9-  EIA report for the extension Project of East China (Jiangsu) 5OOkV Power Transmission Project with some inhabitants. * In design, the Project has been isolated far from urban and township programming areas. No impact would occur to construction of the areas. * In operation of the Project, the electro-magnetic field (EM1F) intensity produced under the design conditions meet the recommended standard. In case some electro-magnetic intensity data under outgoing and ingoing lines of the substation are more than 4kV/m, there is no dwelling in the area though, without impact incurred on residents. * In operation of the Project, noise produced by the substation meet II standard---- (60dB (A), 50dB (A)) ) *The substation's operation will bring production and sanitary wastewater. There will be 830 tons of sanitary water annually to be treated and then discharged. Sanitary water will meet the requirement---- BOD 30mg/L, SS 150mg/LU oil 10mg/L. To the transmission lines: * During operation of the transmission lines, no impact will produce under the design conditions if the lines intercross highways, railways, rivers and existing power lines. * Tower foundations occupy farmland and affect agricultural production, making an annual decrease of 27.0t/a in crop harvest. * As estimated preliminarily, tower foundations will take up 2.37ha land, 10800m houses need to be removed. There are 12 families, about 45 persons. That will bring some impact on residents. * The transmission lines have been designed to shun urban and township programming area. Thus they have no impact on urban and township building. - 10-  EIA report for the extension Project of East China (Jiangsu) 500kV Power Transmission Project * Tower foundations will affect agricultural mechanized farming a little. * The residential house area should be returned to farmland when houses are removed so as to minimize impact on agricultural production. 4 Suggested mitigating measures (1) During construction period * Construction machinery is used during construction of the substation causing construction noise. Therefore, low noise (less than 85dB(A)) construction machines should be applied. Construction will be done at daytime and avoided at nighttime as possible to mitigate environmental impact incurred by construction noise. * Guard fence should be established during construction of the substation. Periodic water spray should be done with excavated naked earth within the substation; soil-transporting vehicles should also be flushed and covered with surface cloth so as to prevent dust from affecting surroundings. * 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 substation. 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. * Sanitary water of construction staff will be treated and discharged complying with the standard to prevent drainage of runoff water. * In design of the substation, proper distance away residential and sensitive areas have been taken into consideration to meet associated - 11 -  EIA report for the extension Project of East China (Jiangsu) 500kV Power 'rransmission lProject design regulations and environmental protection requirements. * The transmission line intercrossing highways and rivers should avoid construction at traffic rush time. * For the land to be occupied by tower foundations and substations, economic compensation will be provided for farmland, houses and crops in strict accordance with Land Management Law of China and requirement of the World Bank. Refer to Table 1 (Page 15) about mitigating measures of the substation. (2) During operation period To the substations: * Use low noise (less than 85dB(A)) equipment as possible. Low noise (less than 85dB(A)) means the noise level is less than 85dB(A). * Make general arrangement of the substation reasonably and arrange the main transformer at center of the substation to minimize environmental impact incurred by operation noise. * In orcler to prevent transformer oil leakage, the accident oil pond (capacity of which is designed to be larger than the transformer's oil volume) has been designed in the substation. Transformer oil can run into the pond directly as any accident happens to the transformer and will be recycled together and reused. *One operational 500kV substation will produce sanitary water of 830t/a, which would be discharged after being disposed through the buried second biochemical sewage treatment system, and meet the standard. * Promote propagation and education on electric equipment safety - 12 -  EIA report for the extension Project of East China (,iangsu) 500kV Power Transmission Project knowledge among the masses near the substation and advise residents close to the substation of the way to do agricultural production safely. * Stand a warning sign near outgoing lines of the substation with high electric field intensity to advise residents not to stay there or do farming for a long time. To the transmission lines: * Self standing towers (without anchoring cables) are mostly used for transmission line stringing. Double circuit mounting on same tower is also adopted so that minimum farmland would be occupied. * The transmission line corridor has been designed to avoid dense residential area. * Dwelling to be removed should be relocated to ensure affected residents have houses and their living standard will not decrease. * The transmission line has sufficient clear height when crossing highways and rivers, which would not cause impact on land traffic and water navigation. * Strengthen education on electric power to residents near the line corridor so that they can farm safely under the line corridor. Refer to Table 1 about mitigating measures of the substation. 5. Environmental management plan The mitigating measures of the proposed and expansion substations have been presented according to environmental analysis results. The environmental management plan has been prepared for construction and operation periods of the Project. Environmental management during construction and operation periods is to be implemented by State Power - 13 -  EIA report for the extension Project of East China (Jiangsu) 500kV Power Transmission Project East China Company and Jiangsu Provincial Electric Power Company; local Environmental Protection Bureau is the supervisor for the work. And State Power Environmental Protection Research Institute is responsible for monitoring and measurement of operation period. Refer to Table 2 (Page 16) monitoring plan of the environmental management plan. 6. Public participation Public participation was carried out by means of holding talks and sending out investigation forms.

This environmental impact assessment (EIA) report describes direct and potential environmental impact incurred by construction of the extension project (called "the Project" below). The report is composed of: (1) Introduction and background (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 Status quo of Jiangsu power grid In coastland of east China, Jiangsu Province is located at Yangtze River down stream delta neighboring Shandong, Anhui, Zhejiang provinces and Shanhi municipality and is one of the most economically developed provinces in China. - 19-  EIA report for the extension Project of East China (Jiangsu) 500kV Power Transmission Project Jiangsu power grid is at the center of and also an important component of east China power grid. Jiangsu Province has jurisdiction over total 13 municipals: Nanjing, Zhenjiang, Changzhou, Wuxi, Suzhou, Xuzhou, Suqian, Lianyungang, Huaiyin, Yancheng, Yanzhou, Taizhou and Nantong etc.. In 2001, all the social power consumption of the province up to 107.844 billion kWh and the highest load 18000MW increased 11.03% and 9.0% separately compared with that of the last year. Till end of 2001, the total installed capacity of T-G sets (above 50MW) in the province had gone up to 21300MW and generating capacity of that year had become 104.012 billion kW-h. The highest voltage level of Jiangsu power grid in operation is 500kV. Till end of 2001, it had owned 26 of 500kV transmission lines with the length of 3207km (including inter-provincial connection lines); 10 of 500kV substations (including switching stations) and 12 sets of transformers, with the capacity of 8000MVA. Currently, 220kV power grid is still main network in Jiangsu Province. The whole network has 142 of 220kV substations with 231 sets of step-down transformers and the transferred capacity of 29549MVA and 319 of 220kV transmission lines 8062.6km long totally (including inter-provincial connection lines). See Figure 1-1 sketch map of the 500kV power grid in Jiangsu Province, East China 1.2 Necessity of construction of the Proiect Although Jiangsu provincial 500kV power grid has developed fast making use of loan from the World Bank recent years, it is still relatively weak. Besides, as the receiver end of east China power network to which Three Gorges transmit electric power, Jiangsu power grid will be - 20 -  EIA report for the extension Project of East China (Jiangsu) 500kV Power Transmission Project beneficial to, by constructing the Project, resolving the said bottleneck problems, strengthening the receiver end network to alleviate pressure on the existing 5OOkV substations for supplying power and improving reliability of the power grid for supplying power. Therefore, it is necessary to accelerate construction of the Project. 1.3 Basis of environmental impact assessment for the Project 1.3.1 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 international financial institutions (8) SEPA HJ/T24 - 1998 Technical regulations on environmental impact assessment of electromagnetic radiation produced by 5OOkV ultrahigh voltage transmission and transfer power engineering - 21 -  EIA report for the extension Project of East China (Jiangsu) 5OOkV Power Transmission Project 1.3.2 Relevant standards The environmental standards to be performed during construction and operation of the substations: (1) GB8978-88 Standard of Wastewater Comprehensive Effluent for wastewater effluent (BOD 30mg/L, SS 150mg/L, oil 10mg/L) (2) GB 12523-90 Noise Limits for Construction Site for construction noise (3) GB3096-93 Standard of Environment Noise of Urban Area, class 2 [60dB (A) at daytime, 50 dB (A) at nighttime] for environmental noise (4) GB12348-90 Standard of Noise at Boundary of Industrial Enterprises, class II [60dB (A) at daytime, 50 dB (A) at nighttime] for noise at the boundary (5) Radio interference The tolerance of radio interference level at 20m (not in outgoing direction) outside the substation enclosure is 55dB ( 1- V/m) (frequency: 0.5MHz) in fine days with relative humidity no more than 80%. (6) Electro-magnetic field (EMF) limits * In case the substation 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, which is deemed to be the recommended assessment standard for electric field. * Magnetic induction intensity limits The limit 0. limT of International Radiant Protection Association for all-day radiation is used as the recommended assessment standard of magnetic induction intensity. 1.3.3 Requirements for power transmission project by the World Bank The World Bank comments that power transmission project as one with - 22 -  EIA report for the extension Project of East China (Jiangsu) 500kV Power Transniission Project provision of extensive environmental risk which depends on engineering scale and position. The incurred impacts are relevant to construction of the substation and risk of electro-magnetic field (EMF). The power line or substation of small capacity need not overall EIA while that of large capacity does. 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. Associated environmental impact analysis has been carried out in compliance with the Framework of EIA Report for the Project (November 2001) discussed and recognized by environmental experts of the World Bank. 1.3.4 Design reports of the Project (1) Feasibility study of the 500kV Longtan Substation project by the East China Electric Power Design Institute, State Power Corporation (ECEPD:[), December 2001; (2) Substation site option report of the 500kV Lianyungang Substation project by the JPEPDI, July 2001; (3) Report of the 500kV Yancheng Substation expansion project by the JPEPDI, October 2001.

At that time, the Project was at the stage of selecting proposed substation site and some engineering designs had not been confirmed. However, we compiled on September 2001 the Framework of Environmental Impact Assessment Report for the Extension Project of East China (Jiangsu) 5OOkV Power Transmission Project so that persons concerned of the World Bank could know our work status, conception and progress as soon as possible. Between 8-9 Nov. 2001, Mr. Baratz, the principal expert of the World Bank, reviewed - 25 -  EIA report for the extension Project of East China (Jiangsu) 500kV Power Transniission Project and put forward modification suggestions on the above framework and investigated the recommended substation sites. SPEPRI has performed EIA based on the framework. The Project at the engineering site-option stage currently has been reviewed and approved by the State Power Corporation East China Company (SPECC). SPEPRI carried out site investigation, environmental investigation (physical, ecological, social and living quality environment), public participation and ambient background measurement (of electric field intensity, magnetic field intensity and noise levels) on the recommended two proposed substation sites, on the expansion site and along the transmission lines. For the reason that the 500kV transmission line is still at indoor route-option stage instead of investigation stage, we know physical environment of areas the line may pass through. This environmental impact assessment report has been compiled on the above basis. The EIA report was delivered to environmental experts of the World Bank at the end of Feb. 2002. The environmental experts offered suggestions on April 25 and we modified and submitted updated repot again according to the suggestions on May 30, 2002. On June 20, 2002, Mr. Baratz, principal expert of environmental protection from the World Bank, went to Shanghai and reviewed that report and provided comments. This EIA report is updated version modified carefully in accordance with the comments. - 26 -  Beijing,* Yan h ~~~~~~~~~~~~~~~~~~Jangsu Yangven<;;, Shandong Province / t 5irovincc u > - *. wt 5 w S~~~~~~~ ~~~ ~~Tian%%an 0 m '(,othe Yellow Sea I / n Che Li teanygcan u X 'tang > ReZ .X5 Yancheng 1 C.) engchen h~~~~~~~ Xutang ~~(I x 750)( , * N~w1y built,~.xpand~d ~kV 5UbSt~ti@I1Yancheng < ~ ~~~~~~~~~~~~~~~ x 750) A nhui Provincevince i h hapohaVg or giangu r h } i i , .1 | I ~~~~~ianshenizeang >;( t It iV050ndon neng andtan _ t . / c} (2x~~~1750) jn (fx 70
