1.General Introduction

1.1Project background

The proposed Nanning-Guangzhou Railway Project (Nan-Guang Line) is a new466.734km double track railway line starting from Nanningin Guangxi Zhuang Autonomous Region, and ending at Guangzhou in Guangdong province in south China. The construction period is expected to be 4.5years, commencing in late 2008 and the line is proposed to be commissioned by end of2012.

According to both Chinese EA laws/regulations and the World Bank Operation Policies 4.01 Environmental Assessment, the proposed project is a Category A project due to its scale of potential environmental and social impact and the sensitivity of the project areas, and full environmental impact assessment report is required.

The EMP specifies project activities, potential impacts, mitigation measures, implementation entities, monitoring entities, budget allocation, monitoring indicators, as well as environmental management and supervision institutional setup and capacity building training program.

This EMP will be part of contractual documents for contractors and supervision engineers. The mitigation measures developed in EMP will be incorporated into preliminary design and detail design, and will be fully implemented by contractors under contractual obligations.

Under Chinese EIA law, an EIA is based on the Feasibility Study (FS) and, after being approved, should not be changed unless there are fundamental changes in the project scope. Because of the rapid design progress, the RAP of NanGuang Railway has been prepared based on the Preliminary Design (PD), which is more detailed than the FS. Compared to the FS, the NanGuang PD reduced the total land acquisition by 4.59% and demolition by 12.10%. In the PD, there are 20 stations, two more than in the FS. Minor adjustments to route alignment have also reduced the total length from 466 km in the FS to the latest estimate of 462 km. The potential impact is assessed and concluded that this will cause little change to the overall impact of the project assuming mitigation measures are implemented effectively during construction.
