This document is the summary of the environment impact assessment of the WB loan application project – Jiangxi Shihutang Shipping and Hydropower Pivotal Project at the Kan River, providing the main conclusions of the environment impact assessment and environment management plan of the project, including related laws, law framework, applicable standards, important adverse impacts on natural and socio-economic environment, substitute scheme comparison and selection, mitigating measure design, public consultation procedure, and the environment management plan of the project. This Summary can be submitted to the board of executive directors of the World Bank for review and approval and can be provided to the environment protection authorities, affected groups, non-governmental organizations and wide public as a brief report too.
1.1 Background of the Project
The Jiangxi Kan River Drainage Area Planning Report approved by the Chinese Government recommends two trunk stream cascade development plans I and V through analysis on antiflood, hydropower generation, shipping, water resource application, construction condition, investment, cost and benefit etc. Plan I is an eight-step development plan (Xiashan High Elevation Plan), from upstream to downstream is Xiashan, Maodian, Wanan, Taihe, Shihutang, Xiajiang, Yongtai and Longtoushan. Plan V is a ten-step development plan (Xiashan Low Elevation Plan), from upstream to downstream is Bai’e, Baikoutang, Xiashan, Maodian, Wanan, Taihe, Shihutang, Xiajiang, Yongtai and Longtoushan. The two plans are the same just at the river section downstream Ganzhou, i.e. six steps of Wanan, Taihe, Shihutang, Xiajiang, Yongtai and Longtoushan are arranged. The planned preliminarily selected projects that will be implemented in the near future are the three steps of Taihe, Shihutang and Xiajiang.
The Kan River is the main tributary at the middle reaches of the Yangtze River, and it is one of the key passages for shipping of Jiangxi province and has been listed into the state high-rank waterway network. As per the “Approval of Technical Grade of Inland River Waterway” (Document No. 659) issued by the Ministry of Communications, the Ministry of Water Conservancy and the State Trade and Economic Relation Commission in 1998, the 525km long section of the Kan River (Ganzhou to Wucheng) is graded as Grade III inland river waterway.
From the angle of comprehensive benefits, completion of the Project will channelize 38km long waterway (Grade III), making the Grade III waterway of the Kan River to further extend to upstream, and to finally reach the planned waterway objective; Shihutang hydropower station will participate in peak regulation of the Jiangxi power grid together with the upstream Wan’an hydropower station, it will play an important role in lessening the contradiction of power shortage of Jiangxi Province and will increase hydropower proportion over the Jiangxi power grid, and help to improve the energy structure of Jiangxi province. The project geographical location is shown in DRAWING NO.01.
1.2 Preparation Basis
1.2.1 World Bank Requirements
The World Bank requirements include primarily the Bank’s ten safeguard policies, including Operational Policies (OP), Best Procedure (BP), Good Practice (GP) and Operational Directives (OD). These safeguard policies are:
Environmental Assessment (OP/BP/GP4.01);
Natural Habitats (OP/BP4.04);
Safety of Dams (OP/BP4.37);
Pest Management (OP4.09);
Involuntary Resettlement (OP4.12);
Indigenous People (OD4.20);
Cultural Property (OP4.11);
Projects in Disputed Areas (OP/BP/GP7.60); and
Projects on International Waterways (OP/BP/GP7.50).
Among these safeguards policies, Environmental Assessment (OP4.01) is the primary requirements and thus will be fully applied in this report and other EA documentation. In addition, other safeguard policies will first be screened during the EA and fully applied if triggered by the screening. Safety of Dams (OP/BP4.37), Natural Habitats (OP/BP4.04), Pest Management (OP4.09) and Forestry (OP/GP4.36) will be applied in this Report too. Involuntary Resettlement (OP4.12) and Cultural Property (OP4.11) will be applied in by two separate teams, but the major findings and subsequent assessment will be included in the EIA process and the EIA reports.
Since there are no project components that involve international waterways (OP/BP/GP7.50), indigenous people (OD4.20) or disputed areas ( OP/BP/GP7.60), policies related to these subjects will not be applied in the EIA.

2.0 BRIEF INTRODUCTION TO THE PROJECT
The Project is between the Ji’an City proper and Taihe County seat at the middle reaches of Kan River, the dam site is situated at the Kan River nearby Shihutang Village, 26km downstream the Taihe County Seat Road Bridge. It is a multipurpose project, which takes shipping as the main purpose, gives consideration to power generation and flood control. The project belongs to second-class large (2) type project, with normal impounding level of 56.50m, total reservoir capacity of about 632 million m3, the reservoir area at normal level of 29.2km2，backwater length of 38km，6 water turbine power generating sets, installed capacity of 117MW，annual average power generating capacity of 4.8×108kW·h，belonging to low head building.
The main buildings of the pivot are flood discharge scouring sluice, ship lock, hydropower station, earth rockfill dam at left and right banks and the dam bridge; The engineering contractor recommends the arrangement plan of the right ship lock and left powerhouse as follows: Ship lock is arranged at the right bank so as to apply the concave bank to arrange approach channel; At the trunk channel at the left close to the ship lock are respectively arranged 21-hole flood gate and 3-hole scouring sluice; At the left bank close to scouring sluice are arranged 6-power-generating-set powerhouse dam section, earth rockfill dam section at both banks are connected with the bank slopes.
The total length of the scouring sluice is 584m. The internal and external approach walls of upstream approach channel of the ship lock are 135m and 240m long respectively，the internal and external approach walls of downstream approach channel are 118m and 240m long respectively，all in gravity type or semi-gravity type structure. The main machine room (dam section) of the hydropower station is 145.02m long in total, total downstream width is 88.89m. The voltage grade of substation is 220kV.
