Introduction 1. This Environmental Impact Assessment Report (Project EIA) for the Integrated Yunnan Road Network Development Project (the Project) was prepared by Yunnan Provincial Department of Transport (YPDOT). It is based on Environmental Impact Assessment for Longling to Ruili Expressway Project.1 (Expressway EIA) and No. 12 East to West Expressway of National Highway Trunk Network System Hongzou to Ruili Expressway Longling Ruili Section Feasibility Study Report 2 (Feasibility Study Report). Project EIA also includes contents of Asian Development Bank (ADB) financed Project Preparatory Technical Assistance final report3 (PPTA Final Report) and on going Preliminary Design for the Longling to Ruili expressway4. The author greatly appreciates Yunnan Provincial Department of Transport, Environmental Protection Bureau, Yunnan Highway Administration Bureau, Yunnan Longrui Expressway Company, Dehong Prefecture Communication Bureau, Dehong Prefecture Forest Bureau, Yunnan Communications Design Institute, Wanding Economic Development Zone, Wanding Construction Bureau, Wanding Environmental Protection Bureau, and Wanding Planning Bureau for information provided by them. 2. The Project has four components: (i) construction of Longling-Ruili expressway,5 including class II highway (linking road) from Ruili to Nongdao and interchange linking roads, (ii) Yunnan Local Road Rehabilitation, 6 (iii) Maintenance subproject and Gender and Development (GAD) Rural Road Maintenance component,7 and (iv) Enhance performance by capacity building. The Project’s Environment Management Plan (EMP, Appendix 1) was prepared incorporating measures described in the Project EIA. For Local Road Rehabilitation and GAD, environmental assessment and review framework (EARF, Appendix 2) was prepared by the PPTA consultants. Detailed environmental assessment information such as expressway plan, vegetation map, list of environmentally sensitive points, and list of flora and fauna is in Appendix 3. a) Expressway EIA Preparation 3. Complying with the Regulation on the Administration of Construction Project Environmental Protection (State Council Order 253, 29 Nov 1998), Dehong Prefecture Communication Bureau (DPCB), as the representative of Yunnan Provincial Department of Transport (YPDOT), contracted Chongqing Communication Research Institute as the consultant to conduct the Expressway EIA for Longling to Ruili in November 2007. The expressway component includs 123.79 km of expressway from Longling to Ruili and 34.38 km of Class II 1 Chongqing Communications Design and Research Institute. 2009.

With the assistance of the YPDOT and other relevant government departments, the Expressway EIA team undertook field work including site investigations and data collection between November 2007 and May 2008. During the period, public consultation and information disclosure was conducted. Further public consultation was conducted in June and July 2008 and again in September 2008. A draft EIA report was submitted in March 2009 to PRC Ministry of Environmental Protection (MEP) for review and the full approval was received from MEP in November 2009 following the reviews by a MEP’s expert panel and by Environmental Protection Office of MOT. 5.
