General

1.1 Background and Scope of the Project

The Shaying River has a very long history of water transport. Since antiquity, its water transport has been in a constant process of suspension, improvement and resumption. From 2012 onwards, a three-year-long improvement effort began for the length of the Shaying River in Anhui. As the last ship lock in the downstream navigation channel, the Yingshang Ship Lock passed the EIA acceptance test of the Anhui Provincial Environmental Protection Department in July 2012. With the completion and commissioning of the Fuyang Ship Lock, navigation for the whole stretch of the Shaying River has resumed. As the existing Yingshang Ship Lock is inadequate to meet the navigation requirements, a new bottleneck problem stands in the way of greater transport capacities. In order to cope with the pressing demand for inland navigation, Anhui Provincial Port & Shipping Construction Investment Group (hereinafter referred to as “APPSCI”) has proposed to expand the capacity of the existing Yingshang Ship Lock. The proposed Yingshang 2nd Waterway Ship Lock Project (hereinafter referred to as “the Project”, “the Proposed Project” or “the Work”) is an extension of the existing Ship Lock as well as a subproject of the Shaying river channel improvement project financed by a World Bank loan. Anhui Provincial Department of Transport has included the Project in its 12th Five-Year Water Transport Development Programme and the Anhui Provincial Development & Reform Commission has officially approved the proposal submitted by APPSCI.

The Proposed Project is to be sited on the right of the existing Yingshang Suice Gate of the Shaying River channel, or more precisely, on the diversion dam between the Yingshang Sluice Gate and the existing Yingshang Ship Lock. It is located 80km from the upstream Fuyang Ship Lock and 45km from the downstream Mohekou Town. The geographical location of the Project is shown in Att. 1 and Fig. 1-1.

The Project is to be built against Grade IV navigation channel standards, with a design tonnage of 500t (up to 1,000t) and a maximum annual unidirectional navigation tonnage of 12 million tons. The lock chamber has a dimension of 200×23×4.0m (Length*Width*Water Depth at Lock Sill). The upstream and downstream approach channels have a length of respectively 540m and 760m. The upstream approach channel, measuring 80m across at the bottom, is shared with the Single Waterway Ship Lock. The downstream approach channel is built independently and measures 40m across. A new ship lock management facility will be built. 300.34m of bridge renovation work will also be involved. The total area of the Project is 50.26hm2, including an additional 49.45 hm2 for the Work. The additional area includes 9.90hm2 for permanent uses (intended primarily for hydraulic engineering purposes; it comprises 0.81hm2 for the Single Waterway Ship Lock and an additional 9.09 hm2) and 40.36hm2 for temporary uses (dominated by tidal flats, arable land and construction-purpose land for the Single Waterway Ship Lock).

The Project involves 2.1169 million cubic meters of cut work (including 118,300m3 of overburden soil stripping and 2,400m3 of rubble generated by the demolition of the existing management facility and the renovation of a bridge), a total backfill work of 644,400m3 and a total spoil work of 1.4725 million cubic meters. 13,500m3 of overburden soil will be dumped in two temporary spoil areas, 3,300m3 of overburden soil will be dumped in a corner of the Site of the Project (hereinafter referred to as “the Site”), 101,500m3 of overburden soil will be dumped in a corner of the spoil areas, 2,400 m3 of rubble will be used for subgrade fill and the remaining 1.3518 million cubic meters of spoil will be transported to the spoil areas. The actual total spoil work is 1.3518 million cubic meters, which will be transported to the spoil areas. The planned construction period is 30 months and the total investment is RMB274.3706 million.

1.2 Environmental Protection

As stipulated by construction project environmental management procedures and applicable national environmental protection laws and regulations, APPSCI employed Beijing Zhongzi-Huayu Environmental Technology Co., Ltd. (hereinafter referred to as “ZHET”) to prepare the Environmental Impact Assessment Report on the Shaying River Yingshang 2nd Waterway Ship Lock Project (domestic edition; hereinafter referred to as “the EIA Report” or “Report”) in March, 2013 at the feasibility study stage of the Project. The EIA Report was approved by Environmental Protection Department of Anhui Province. In order to further control the quality of the Report and fulfill the World Bank’s requirements, ZHET made further changes, supplements and revisions to the Environmental Impact Assessment Report on the Yingshang 2nd Ship Lock Project as a Subproject of the Shaying River Channel Improvement Project in compliance with the requirements of the World Bank’s procedures. World Bank’s experts reviewed the Report in January 2014, making comments on the basis of which ZHET made further revisions.
