2 INTRODUCTION The People's Republic of China has requested a loan from the World Bank to help finance improvements in its inland waterway system. This loan, the Bank's fourth for China's inland waterways, would cover planned investments in Guangdong Province and Guangxi Zhuang Autonomous Region. The Guangdong Provincial Dept. of Communications (Waterway Bureau) (GDWB) has prepared Environment Impact Assessment (EIA) and Environment Action Plan (EAP) documents to meet national policy and administrative requirements for environmental assessment of development projects in China, as well OP 4.1 (Environmental Assessment) of the World Bank. A listing of relevant Chinese laws, regulations and standards, applicable to the three subcomponents, is provided in Annex 1. The Guangdong sub-components are: (1) improvement of Laolonghu Waterway, (2) improvement of Middle Reaches of North River and (3) construction of Xiniu Dadshiplock on Liang River (tributary of the North River). Detailed summary environmental assessments for each sub-component are provided in Annexes 2, 3 and 4. SUB-COMPONENT DESCRIPTIONS LaoLonnHu Waterwav Improvement: This component provides for navigational improvements to an existing 16 km channel, located in the lower reach of Xi River on Jiangmen City at the western side of the Peal River Delta. The component forms part of the Pearl River Delta Master Plan, which was also partially addressed within China 2nd Inland Waterways Project. It will facilitate movement of 1,000 DWT class vessels from Guangxi, Guizhou, and Yunnan to Hong Kong or Macao. The sediments are mostly fine silts and clays. North River (Bei Jiang) Channel Improvement: This component provides for navigational improvements to five sections (75 km) of the River between Shaoguan City and Qingyuan City. It will enable 300 DWT class vessels to navigate the 184 km section during all seasons. The riverbed in the upstream consists of sands, pebbles and some bedrock, in the middle stream of sand and pebbles, and in the lower stream of sands mixed with small pebbles. Xiniu Navigation Complex: This component will be located in the northwest of

3 Guangdong Province on the Lian River, the largest branch of the North River. The project site is located 3.5 km upriver of Xiniu Town and about 20 km from the confluence with the North River. The complex will be constructed between two sandbars in the middle of the river. This component is the last and the most down stream of 12 steps that have been developed along the Lian River. This component includes (1) shiplock for 100 DWT vessels; (2) construction of a dam (8.5 m height) and powerhouse (36 MW capacity); and (3) dredginghegulation of 1.6 km of the Lian River. Construction of the complex will inundate 95 ha of land. BASELINE ENVIRONMENT DESCRIPTION Climatic Conditions. All the sub-components are located in the sub-tropical monsoon zone. The rainy season is from May to October in general, and average rainfall is from 1,100 mm to 2,500 mm. The average annual temperature is from 20 C to 22.7 C. Social Situations. (1) LaoLongHu Waterway: Jiangmen City has a population of 420,000 with an average per capita income of 4,43 1 RMB for farmers and 9,525 RMB for non-farm workers. (2) North River Regulation: The population of Shaoguan City and Qingyuan City are 3.1 and 3.9 million respectively, and average per capita income is 3,300 RMB. (3) Xiniu Navigation Complex: The population of Xiniu Town and surrounding villages is about 20,000 with an average per capita income of 2,500 to 3,120 RMB. The major industry is agriculture. Ecological Environment. LaoLongHu Waterway Improvement. LaoLongHu is located in a relatively undeveloped area near Jiangmen City. Site investigation was conducted along the project site (16 km in total), quarries, and dumping sites. The EIA report identifies no protected area or critical natural habitats within the impact area of the project site, which was confirmed with local authorities as well. North River Channel Improvement. The EIA report identifies the Yebei and HuaNanHu Nature Conservation Areas, but both are more than 100 km away from the projects sites. The project design provides that no civil works will be conducted within or near upstream of the three no-fishing areas in Qingyuan City. Site investigation involving local academic experts identified no critical habitats of fauna and flora and the results were confirmed with local authorities. Xiniu Navigation Complex. The vegetation around the project site is farmland and bamboo bush. The 95 ha area to be inundated is mostly within the existing flood plain and is 90% bush, 5.6% bamboo and 3%. The EL4 report identifies no protected areas or critical natural habitats near the

4 project site. This finding was confirmed with local authorities. Water Quality. The proposed projects sites are remote from large populated areas or major industrial sources of pollution. According to the monitoring data during past several years, all the project sites in general comply with Class I1 or I11 water quality standards; water quality at the Xiniu Navigation Complex is as good as Class I. There is a drinking-water intake at Xiniu Town. Sediment Quality. The proposed projects sites are relatively remote from populated areas or major industrial sources of pollution. Sediments are acceptable for disposal on land as fill materials. Existing Noise and Air Quality. The noise levels at villages around the Xiniu Navigation Complex have almost reached the maximum allowed under the national standard because of existing commercial activities. Noise mitigation measures and monitoring to address this situation will be implemented. Air quality measurements are within appropriate national standards. Cultural Relics. Archeological authorities conducted investigations using both document reviews and site inspections. At LaoLongHu, four sunken ships from the Tang Dynasty were found within the Waterway, but not in the actual project areas. The provincial antiquities bureau concluded that the proposed project would not impact the sunken ships due to distance. POTENTIAL ENVIRONMENTAL IMPACTS AND MITIGATION MEASURES LaoLongHu Waterway Improvement. Analysis of Alternatives. Three alternatives for routes, two alternatives for changes to the channel alignment, two alternative sources for quarries, and the no-project alternative were analyzed. The selected route and alignment provide the best benefits in terms of both engineering and environment. The selected channel alignment also provided for the best curvature providing for the minimum of excavation and therefore environmental impacts. Both quarries satisfy the needs of the project and the one with the poorer existing vegetation was selected. Construction Phase. The identified major environmental issues during construction are: (1) water pollution, (2) waste material dumping, (3) nearby residential area, and (4) the aquatic ecological environment. Proposed mitigation measures are as follows: The major source of suspended soliddturbidity will be the actual clamshell dredging and upland disposal. Multi-cell sedimentation ponds will be constructed for each

5 dumping site, with a discharge control of 70 mg/l for suspended solids. Waste material dumping sites were selected in consultation with local governments. They are a combination of an unused river channel and borrow pits from earlier town construction. Dredged materials will be hydraulically pumped to each dumping site. (a) Sediments proposed for dredging are relatively uncontaminated due to the limited industrialization or urbanization of the general waterway area. (b) A large portion of the proposed excavation (channel bend re-alignment) will be conducted in the dry to significantly reduce impacts to the aquatic environment. (c ) Noise and dust prevention measures related to bridge re-construction near a residential area, will include limiting the construction schedule and spraying water. (d) Blasting and regulation work will avoid fish reproduction seasons. All disturbed vegetation will be rehabilitated including the quarry and dumping sites. Operation phase. This component would rehabilitate the existing waterway and enable it to be used by larger ships. While a higher volume of traffic is expected, there will be a decrease in the chance of accidents causing oil spills. The risks associated with the project works are considered to be minor, and no major environmental issues are identified for the Operation Phase. North River Channel Improvements Analysis of Alternatives. Five sections of the river will be dredged and regulated. For sections A, B, and E, there are options in terms of engineering specification of regulation. Combining these options, three alternatives were developed. The three alternatives and the no-project alternative were analyzed. The recommended alternative minimizes the extent of construction of spurs and groins, reduces the need for blasting of shoals to none and minimizes the amount of dredging. The EL4 report concludes the recommended alternative is the best from both the environmental and engineering viewpoints. Construction Phase. The potential major environmental issues during construction are: (1) water pollution due to increased suspended soliddturbidity, particularly in water protection and no fishing areas; (2) dumping of dredged materials and (3) protection of fish and other aquatic organisms. Because there are no terrestrial aspects of this component, no major impacts to terrestrial vegetation are expected. No residential areas were identified within the project impact zone. Proposed mitigation measures are: (1) During dredging, silt curtains will be deployed to contain waters with elevated concentrations of suspended soliddturbidity. The dredged materials will be dumped by pump-style equipment to minimize dispersion. (2) Sediments proposed for dredging are relatively uncontaminated as much of the material is medium to coarse sand and fine to medium cobble. (3) Dredged materials will be dumped at designated dumping areas either in deep off-channel

6 areas or between river regulation groins. (4) No blasting will be conducted and regulation work will avoid fish reproduction seasons. The project will cooperate with the fishery authority to release fry to the river. Operation Phase. This component will rehabilitate the existing waterway and enable it to be used by larger ships. While there will be higher volume of traffic, there will be a decrease in the chance of accidents causing oil spills. The risks associated with the project are considered to be minor, and no major environmental issues are identified for the Operation Phase. Xiniu Navigation Complex Analyses of Alternatives. As this component is the last of 12 dams/shiplocks modifying the Lian River, final site alternatives were limited. Three alternatives for the location and the no-project alternative were analyzed. The EIA concluded that the proposed location is good for the engineering and the environmental because it requires the least amount of civil works. The reservoir water level was determined at the minimum to ensure year-round navigation for 100 DWT vessels to the next step up the river. Construction Phase. The potential major environmental issues during construction are: (1) water pollution due to increased suspended solids, particularly with respect to the drinking water intake at Xiniu Town, (2) waste material dumping, (3) protection of residential areas, and (4) protection of the ecological environment. Proposed mitigation measures are: During construction of the cofferdams and excavation of the facility foundation, the project will coordinate with Xiniu Town water utility to protect the quality of water at the intake. Settling ponds will be constructed to control the concentration of suspended solids in the discharges within the national standard of 70 mg/l. Sewage wastewater from the construction camp will be subject to both chemical and biological treatments before discharge. Soil and rock from construction of the complex will be reused at the construction site. Material dredged from the river will be dumped into the river to augment river regulation. No waste material dumping sites will be established outside of the construction area. The transportation routes for the quarried rock were surveyed and one school was identified as an environmentally sensitive site. Noise and dust prevention measures will be taken. With respect to the ecological environment, the EIA report does not predict significant impacts for aquatic fauna and flora because of the small size of the complex and that this is the last and the most downstream step of 12 that regulate the flow of the Lian River.

7 To rehabilitate fish resources, the Waterway Bureau proposes to introduce a variety of fish species. In addition, all disturbed vegetation will be rehabilitated. Operation Phase. No major environmental issues are identified. Oil leakage from the vessels during normal operation will be monitored by the Dept. of Communications. An action program and placement of necessary response equipment for accidents will be prepared. CUMULATIVE AND INDIRECT IMPACTS LaoLonnHu Waterway Improvement. The Pearl River Delta is one of three major areas within China that have a significant potential for transportation improvement through the use of inland waterways. The Delta is being developed within a Master Plan with improvements to three major north-south and three major east-west waterways. The China 2nd Inland Waterway Project (Loan CHA 4328), currently being implemented, will enhance two of the other waterways. The major cumulative impacts of these developments are alteration of riverbanks, increased water pollution from shipping and changes in waterway hydraulics. The EIA concludes that good protection works of the riverbanks, installation and good management of wastewater-collection tanks in ships and good treatment of wastewaters at land-based facilities will be able to control the pollution. Further, the changes in waterway hydraulics were modeled and the channel designed to address issues of siltation. The EIA report predicts limited induced environmental impacts associated with the expansion of port and terminal facilities located on other or adjacent waterways as their design will address impacts related to land use and highways. Industrial development of the Tan River valley is and will occur irrespective of the waterway project. There will be a beneficial induced impact as shipping traffic to Hong Kong will be able to use a shorter and more protected waterway than the current South China Sea route outside the delta. North River Waterway Improvement. The EIA report analyses cumulative impacts related to the existing three dams/shiplocks and their reservoirs and earlier modifications to the lower section of the River. The major issue will be water pollution caused by suspended sediments and its secondary impact to aquatic ecology. The impact will be short-term based on occurrence only during construction and will be controlled through timing of construction and the use of silt curtains. As to the indirect impacts, which are significant threats to the existing water quality and fish protection zones, the proposed improvement will reduce navigation problems and reduce riverbank erosion through the use of river regulation groins.

8 Xiniu Navigation Complex. From 1959 to1974, 11 water resources dams were constructed on the Lian River with provision of shiplocks to enhance river navigation. The major deleterious cumulative impact has been the interference to migratory fish species; however, as the proposed component will be the last in the Lian River, additional cumulative impacts are not expected. Local communities have been taking various measures to recover fish resources, including stocking of headponds. The component is part of a larger economic development and poverty-reduction effort in the northeastern part of the Province. The proposed improvement of river transportation will enhance such resource industries as coal, cement, metallic substances, construction materials and local agricultural products, as well as improve irrigation capacity and contribute to agricultural productivity. ENVIRONMENTAL MONITORING Monitoring will be carried out to verify predicted impacts, identify unexpected environmental problems at an early stage and implement/adjust mitigative measures, as appropriate. For example, the concentration of suspended solids in the effluent from sedimentation ponds will be monitored at least twice per week, with the rate of discharge adjusted to comply with the national standard. Monitoring will cover both pollutionrelated and ecological environment issues. Monitoring will be conducted by independent monitoring institutions to be selected through a bidding process. The results of monitoring will be reported both quarterly and annually to the Bank and to relevant local authorities. An example of the environmental monitoring plans is provided in a table below. INSTITUTIONAL ARRANGEMENTS AND TRAINING The Department of Communication will assign staff to be responsible for the implementation of environmental protection. An organization will be or has already been established to implement the project. The implementing organizations will have a department in charge of environmental protection and full-time or part-time staff will be assigned. At local levels, supervision groups will be set up for each contract. One of the members of each group will be assigned for environmental supervision. Rules on reporting of findings and recording of actions will be established to facilitate effective supervision. Local environmental authorities continue to work on the project. They and their field offices will independently oversee the compliance issues. The project will provide the results of the environmental monitoring to them.

9 Implementation of the EAP will be a part of the contract between the Department of Communication and contractors. Each contractor will be required to assign one or more staff members to the project for environment protection activities. To enhance environmental protection knowledge and skill, staff in charge of environmental protection will receive training. The training program is proposed to include lectures by experts, site visits to similar projects and national and international training. A training budget of US$398,000 has been allocated. PUBLIC CONSULTATION AND INFORMATION DISCLOSURE Public Consultation and Feedback. During preparation of the TOR and the EM, people within the project areas were intensively consulted. Apart from the resettlement-related issues, the public showed a wide range of concerns from water quality at drinking water intakes to noise impacts to schools. Their opinions have been reflected in the final project design and mitigation measures; e.g., upgrading the level of wastewater treatment at the construction camp, avoiding shoal blasting within a fish protection zone, location of a new bridge, and planting of trees within the reservoir catchment area. A two-stage public consultation was carried out according to the World Banks guideline: (a) shortly after environmental screening and before the terms of reference for the EA were finalized; and (b) after the draft EA report was prepared. The consultations were conducted through meetings and surveys, with questionnaires at towns and villages near the project sites. The number of people consulted at the last stage is estimated as 3,68 1 including individual citizens, organizations of concerned villagers, and village committees. A summary of consultation activities appears in the tabie below.

10 advertisement in local and provincial newspapers. LESSONS LEARNED FROM EARLIER WATERWAY PROJECTS The GDWB is currently implementing the Second Inland Waterway Project financed by the Bank and has gained several lessons from that experience: Impact on environment by construction activities. From evaluation of the environmental monitoring program, it was learned that during the construction of the waterway project, apart from the excessive suspended solids/turbidity, the concentrations of petroleum hydrocarbons within the project area also surpassed the COD and BOD standards compared to outside the construction area. It was concluded that petroleum hydrocarbons from the construction ship and sanitary sewage from the construction site drained into the water body requiring that collection and/or treatment equipment should be r improved. Although dredged sediments were dumped in specific confined disposal facilities, concentrations of suspended solids in excess of standards sometimes occurred downstream of the disposal sites. This was attributed to an inadequate retention time. Fortunately no disposal areas were located upstream of potable water intakes. In future projects of the same type, strict management of the disposal process and discharge water retention time is key to protection of water quality The impact of blasting of shoals and rock outcrops on inland water transportation is limited in duration. While the blasting noise exerted some impact to adjacent riverbanks and nearby vessels, other construction noise posed no impact to residential areas. Function of Environmental Protection Action Plan. Within the context of the general water quality issue within the Pearl River delta area, impacts associated with waterway upgrading projects are much less significant or severe. When GDWB submits an EIA, it also commits to the State and Guangdong Provincial Environmental Protection Administration to implement the associated EAP. The combination of commitments forms a solid foundation for effective water environmental protection and management during construction, as well as providing reference for future environmental protection activities during the operation period. The EAP identifies the project environment management organization, their responsibilities and operating processes, targets for protection in the construction phase,

11 environmental protection measures in the design, construction and operation phases, an environment monitoring plan for the construction and operation phases and the estimated cost of environmental protection. The EAP not only ensures a smooth relationship between different environmental protection works during construction, but also defines the procedures and tasks in each step. For the Fourth Inland Waterway project, the functional components of the EAP s for the 2nd Inland Waterway Project shall be adopted with the EAP s being legally binding and the key items of the EAP s being incorporated into the contracts, all with the objective of reducing impacts of construction and operation to the receiving environment. Function of Management Program. To exert effectively environmental protection management during construction, specific project organization elements with responsibility for environmental protection have been established. Specific responsibilities and rights have been assigned to persons representing the owners, as well the supervisors. A set of management guidelines have been stipulated, aimed at protecting the environment, including overall construction management guidelines, management of waste collection from construction ships, management of dredging and sediment disposal, as well as other correspondent supervision guidelines. Strict enforcement of the guidelines and practices ensures that all environmental protection measures have been carefully carried out and environmental impacts related to the construction have been kept to the minimum level. Use of Appropriate Construction Techniques and Procedures. To minimize environmental impacts related to waterway construction, the construction teams have optimized their construction pladschedule and adopted the latest methods. This included reducing the quantities to be dredged and the amount of the rock blasting. Other procedures included: tried to methods of reducing the impact of suspended solids released to the waterway; use of highly explosive detonators to lessen the amount of the explosives; using mechanical methods to replace blasting; not blasting during fish migration periods; optimizing dredge practices to reduce channel slopes and therefore mitigated the influence of the flood discharge to the river. In future construction, GPWB shall ensure the construction team adopts the appropriate techniques and procedures to further optimize the construction program. Function of Construction Monitoring. As described in the EAP s, the Owner contracts with qualified organizations to undertake the environmental monitoring and mitigative measures, associated with the construction phase. Maintenance of water quality, river ecological environmental quality, noise levels, dust and other environmental factors were implemented according to the EAP s, augmented by specific activities during construction. By means of the environmental supervision activities, the impact of

12 construction on the environment could be identified in a comprehensive and timely manner. As problems occurred, effective measures were taken and results reported to the parties concerned. In this way, a scientific basis has been provided for environmental management during the construction of the waterway. Rational budget. After the construction began, the work burden for environmental management was significant, covering many departments and requiring significant amounts of human and material resources. As the cost of environmental management in the project was allocated when the action plan was drafted, sufficient funding was provided to enable proper implementation of all environmental protection measures. This enabled GPWB to fulfill the tasks in accordance with timing of the plan and provide a guarantee for the implementation of all the environmental protection measures. Using the lessons learned from the earlier project, GPWB believes that it can fully implement a complete environmental protection program in the proposed fourth inland waterway project and hence further enhance its capacity in the environmental protection of waterways.

16 1. INTRODUCTION 1.I Project Overview The Report on Planning for Comprehensive Utilization of Yujiang River of Xijiang River Water System of Pearl River Basin identified the need to improve the navigability of the Yu River/Xi River system to facilitate passenger and freight traffic from interior southwestern China to Guangzhou, HongKong and other coastal communities. The Report evaluated various alternatives and recommended construction of 10 steps, each to consist of a dam and shiplock ( navigation complex ) with a resultant navigable headpond. The proposed Naji Navigation Complex would form the fourth of the 10 steps. The Guigang Navigational Complex constructed in the late 1990 s as part of the China 1 Inland Waterway Project financed by the World Bank formed the third step. The proposed Complex will be located near Naji Village, 4.5 km from Nap0 town, Tianyang County. Geographic location is E N. The damsite is 61.8 km from the Baise Dam (more formally known as the Baise Water Conservation Junction) and 55.6 km from Dongsun Dam (refer to Map NO. 1-1). The project will consist of three key aspects: (a) Naji Navigation Complex, (b) river channel improvements from Baise to Nanning, and (c) construction of associated roads and bridges. 1.2 Project Description: Naji Navigation Complex Immediately after completion of construction (2010), the navigation capacity will be 500 DWT vessels, with long-term plans (by 2030) to provide for 1000 DWT capacity. The adopted design will provide for the ship lock on left bank (proceeding downstream) and power and other associated buildings on right bank. The shiplock will be a Class Ill structure, with effective size of 190 m (length) X 12 m (width) X 3.5 m (water depth). The normal water level at Naji is 115 m above sea level with low water at 114.4m. The planned storage capacity will be 103 million cu m, which will inundate ha of farmland and displace 369 people. The flood control structure (concrete gravity structure) incorporates a low-weir open-type large orifice gate format with 10 gates each of 16 m size. The recommended crest level is 104 m. The length of the dam is 97 m, with a maximum height of 22 m. The hydropower station will consist of a recommended 57 MW installed capacity, with the annual average electric generation of million kw.h. 1.3 Project Description: Channel Dredging and Regulation The river channel from the Baise Dam to Nanning (Yongjiang Bridge) is Km of which Km is natural river channel. The Baise Dam to Nanning 1

17 contains 135 dangerous shoals, of which 100 will need to be addressed to meet proposed navigational requirements. The river channel from the proposed dam to the approach channel of the Baise Dam is 56.0 Km This section contains 9 dangerous shoals that will need to be addressed to meet proposed navigation requirements. All materials will be dredged or blasted and dredged. It is proposed to dispose of the dredged materials in deeper sections of the River or in off-channel sections. 1.4 Project Description: Roads and Bridges Two sections of new roadway will be constructed to Class Ill National Standards: Km on the left-bank and Km on the right-bank. The Project will also include construction of the 450 m Naji Youjiang Bridge. This will be located 200 m upstream from the proposed dam. Within the region affected by the new reservoir, Km of Class IV road needs to be constructed and 4 Km need to be upgraded. In addition, three new bridges (25m Dameitun-Baifendi bridge; 5.0m Baigutun-Bake Sugar Factory bridge; 70m Natang Pumping Station bridge) will need to be constructed Identification of Environmental Impacts According to the principle of classification of the works of environmental impact assessment for World Bank projects, this project shall be evaluated as Category A. The applicable standards and classes for monitoring and discharge are summarized in Table 1-1. See Annex 1 for more details.
