E2008 v4 Public Disclosure Authorized Adjustment to New Guiyang-Guangzhou Railway Project Environmental Impact Report Public Disclosure Authorized Abstract Public Disclosure Authorized Public Disclosure Authorized China Railway Eryuan Engineering Group Co., Ltd. June 2012, Chengdu I Project Overview (I) Overview of the original project The New Guiyang-Guangzhou Railway Project starts from the North Guiyang Railway Station and ends at the South Guangzhou Railway Station, via Guiyang City, Qiannan Autonomous Prefecture and Qiandongnan Autonomous Prefecture in Guizhou Province, Liuzhou City, Guizhou City and Hezhou City in Guangxi Autonomous Region, and Foshan City, Zhaoqing City and Guangzhou City in Guangdong Province. The length of main line is 857.300km. The Project is designed as a Class I double-track railway, with a design speed of 200km/h, employing electric traction. In the original plan, there are 317 bridges of 171,411 linear meters, 240 tunnels of 476,660 linear meters and 35 stations. The floor area of the Project totals as 4472.46 ha., including permanent land occupation of 2484.72 ha. and temporary land occupation of 1987.74 ha. The debris volume is 95,562,500m3 and the soil borrow volume is 3,411,800m3. The estimated total investment amount of the Project is 79.9711 billion yuan. The Project is planned to commence in 2008 and complete in 2013, with a construction period of 6 years. In July 2008, the Environmental Protection Department gave reply on the Project with Official Reply on Environmental Impact Report of New Guiyang-Guangzhou Railway Project (HS [2008] No.258). In September 2008, the National Development and Reform Commission gave reply on the feasibility study report of the Project with FGJC [2008] No.2526 Document. In December 2008, the Project was formally commenced. However, in December 2009, variations were made for functional orientation and main technical standards of the New Guiyang-Guangzhou Railway Project. (II) Status of variation of the original project Variations of the New Guiyang-Guangzhou Railway Project mainly include: The railway was changed from a Class I railway to a passenger dedicated line, the design speed was increased from 200km/h to 250km/h, the originally designed freight transportation facilities were deleted, the quality and level of passenger transportation service were improved and the track structure of the whole line was changed from ballasted track to ballastless track. See Table 1, 2 and 3 for details of main changes. 1 Table 1 Comparison on project scope and construction scale Item In the original After adjustment to the Added or reduced environmental scope of feasibility assessment scheme study From CK0+000 to From DK0+000 to CK823+513: The DK829+433.79: The Mileage scope Main line: 3.87km added. length of the main length of main line is line is 857.300km. 861.17km.
