Pertinent departments in Guangdong province commenced the preparatory work of the project from 1994, and the feasibility studies for the waterway regulation projects of the lower Xijiang river and Liansharong waterway had been fulfilled in sequence. In May of 1995, Environmental Assessment Report for Zhaoqing-Hutiaomen Waterway Regulation Project in the Lower Xijiang River (2nd phase) was completed by the Scientific Institute of Pearl River Water Resource Protection, and was approved by Guangdong Provincial Environmental Protection Bureau. In March of 1996, the project put forward the application for the World Bank loan. Based on the negotiation memorandum formulated between the World Bank preparatory group and Chinese side, Guangdong Provincial Waterway Bureau in April of 1996 commissioned the Scientific Institute of Pearl River Water Resources Protection to carry out environmental impact assessment work for Liansharong waterway regulation project, and to supplement and improve the Environmental Assessment Report for Zhaoqing-Hutiaomen Waterway Regulation Project in the lower Xijiang River based on the requirement of World Bank, which aims to mitigate the adverse environmental effects arising from the project, and to guide the environmental protection design and to satisfy the requirement of World Bank on the environmental protection. The objectives to prepare the environmental assessment report for the proposed project include: identifying environmental effects, putting forward environmental protection measures, supplementing environmental monitoring plan, answering the main environmental concerns by public and working out environmental action plan. 1.2 Basis for the Report Preparation (1) Commission Letter of Environmental Impact Assessment issued by Guangdong Provincial Waterway Bureau (the first party), and Technical Service Contract on the Environmental Impact Assessment Work for Zhaoqing-Hutiaomen and Liansharong 5  Waterways Regulation Project in the Lower Xijiang River signed by Guangdong Provincial Waterway Bureau and the Scientific Institute of Pearl River Water Resources Protection (the second party). (2) TOR of Environmental Impact Assessment of Waterway Regulation Project for the Lower Xijiang River (World Bank loan project), prepared by Scientific Institute of Pearl River Water Resources Protection. (3) Reply Correspondence of Review Opinions on the TOR of Environmental Impact Assessment for Waterway Regulation Project in the Lower Xijiang River (World Bank loan project) issued by National Environmental Protection Agency, and its annex Review Opinions on the TOR of Environmental Impact Assessment for Waterway Regulation Project in the Lower Xijiang River (World Bank loan project). (4) The First Screening Group of the World Bank, Memorandum on the Inland Waterway Project in Guangdong Province of China (1996.4.30-5.5), and its Appendix No.3 Environmental Documents to be Submitted to World Bank before 1996.8.30. (5) The Second Screening Group of the World Bank, Memorandum on the Inland Waterway Project in Guangdong Province of China (1996.5.20-5.21). (6) Guangdong Provincial Environmental Protection Bureau, Reply Correspondence on the Assessment Standards of Environmental Impact Assessment of Waterway Regulation Project in the Lower Xijiang River (World Bank loan project). 1.3 Grade, Scope and Standards of Assessment 1.3.1 Grade of Assessment According to the classification principle specified in the World Bank's Environmental Assessment Guidelines (OD4.01), the environmental assessment grade of this project is classified as Class A. 1.3.2 Scope of Assessment (1) The extent of water environmental assessment: the whole regulation waterway, that is, Zhaoqing-Hutiaomen waterway and Liansharong waterway (Nanhua-Lianhuashan). (2) The extent of assessment of noise, vibration and terrestrial plants: the regions within the distance of 200 m away from both banks of the waterway. 6  1.4 Working Procedure and NMethods The working procedure of this assessment is shown in Figure 1. 1. laccept co'mmisssuon |negotiation with preparation group of World Bank| |field surev, data collection and consultation| r |~~~~~~preparation o O environmental quality investigation, data collection, and chemical analysis r~eviwn approvall analysis of exsitingj ipbi atcpto of TOR leinvironmental stat.us i I impact prediction and analysis anendment suDolement |control or mitigation measures] preparation of environmental action plan preparation of EA repotsnmy submit to review and approve Figure 1-1 Working procedure of environmental impact assessment  2 Description of the Project 2.1 Location of the Waterway The waterway in the lower Xijiang river refers to the seagoing waterway from Zhaoqing to Hutiaomen in the western part of the Pearl River Delta, of which the section from Zhaoqing to Baikingtou with a total length of 12; km is called as the lower reach section of Xijiang river, and the section from Baikingtou to Hutiaomen (through Maxi channel) with a total length of 45 km is called as Hutiaomen waterway. Liansharong waterway, with a total length of 90 km, situates in the river network of Pearl River Delta, which reaches Xizhiyang to the east and connects with the mainstream of Xijiang river to the west, and is currently one of the important waterways from Guangzhou to Pearl River Delta, the coastal areas in the west of Guangdong Province and the mainstream of Xijiang river. (For details, see Figures 2-1, 2-2 and 2-3 in the EA report). 2.2 Existing Maintenance Dimensions of the Waterway (Tables 2.1 and 2.2) Table 2.1 Existing maintenance dimensions of the waterway in lower Xijiang river (Zhaoq ing-Hutiaomen) *Length Maintenance dimensions {m} Channel From To ((km) :Depth *Width Curvature radius Lower Xjjian.g R ..!iver .Zhaoi.ng (!nui iiao .45.0 2.5 80 _500 Lower Xijiang River Sixianjiao !Baiqingtou .78.0 .2.5 *50 *360 Hutiaomen Waterway *Baigingtou Hutiaomen *'45.0 .2.5 .50 *360 Table 2.2 Existing maintenance dimensions of Liansharong waterway . *..-..------.... iLength .Maintenancc dimcnsions (m) ... _.. _.... .. _ . _ ....... ........ ..... ...... . ......................................... _ . . .............. ..
