Sections of National Roads (NR) 1, 6, and 67 that will be rehabilitated by RAMP-II are located in Figure 1. The rehabilitation and upgrading designs for the roads meet the requirements of the Environmental and Social Safeguard Policy (ESSP) of the MPWT as well as the safeguard policy (SPS 2009) of the ADB. The rehabilitation of the three national roads will become a loan to the Government for RAMP-II which will be implemented by the Ministry of Public Works and Transport (MPWT). Project Summary The roads to be rehabilitated by RAMP-II in Cambodia at the feasibility design stage are summarized below1. Section Surface National Province Districts length (km) type Road Prey Veng, Kampong Trabek, Preah Sdach 1 100 asphalt Svay Rieng Svay Chrum 6 Siem Reap Puok, Kraluch 50 asphalt Siem Reap, Prasat Bakong, Banteay Srey, Varin 67 134 DBST Oddar Meanchey Anlong Veng Potential Impacts The RAMP-II is Category B for environment because the potential impacts are short-term and reversible. The notable feature of RAMP-II with respect to potential environmental impacts is the rehabilitation and improvements to the three roads will not widen the existing carriage ways or road shoulders. Thus, the impact footprints of NR-1, NR-6, and NR-67 already exist, and were laid down when the roads were last widened between 4 and 14 years ago. The potential environmental impacts of the rehabilitation of the three roads will be primarily from construction phase disturbances. Common impacts of the civil works along the three roads will consist of for example, reduced and/or blocked public access to areas, disrupted business and recreation, noise, dust caused by increased truck traffic and heavy equipment use, soil and surface water pollution caused by equipment operation and maintenance, public and worker accidents, increased traffic congestion & traffic accidents, land erosion and sedimentation of adjacent rice paddy and streams and rivers that are traversed by the roads. Localized drainage and flooding problems can arise. Solid waste and domestic pollution from temporary worker camps can occur, as well as potential communicable disease and local community problems caused by migrant workers. These short-term impacts and disturbances will occur at different levels of magnitude depending on the civil works activity and the road section site. These impacts were also identified by commune leaders and officials at the provincial DOEs. Conclusions 1 From PEC Project Report 7/15, and RAMP-II Inception Report 2 The IEE concludes that the description of the feasibility designs of RAMP-II for NR-1, NR-6, and NR-67 combined with available information on the affected environments is sufficient to identify the scope of potential environmental impacts of RAMP-II. Providing significant changes do not occur to the design of one or more of three road upgrades, and that new sensitive environmental or social receptor data are not discovered, RAMP-II will remain Category B for environment and will not require further detailed environmental impact assessment (EIA). The rehabilitation of sections of NR-67 that are inside the three Protected Areas requires particular care and attention to ensure all construction disturbances and potential impacts are absolutely minimized. The specific impact mitigation subplan of the Mitigation Plan of EMP which keeps all roadwork activity inside the Park to a minimum must be followed closely. The EMP developed for RAMP-II provides impact mitigation plans, environmental monitoring plans, and specify the institutional responsibilities and capacity needs for the environmental management of RAMP-II. The EMP will need to be reviewed and updated at the detailed design phase to ensure that EMP fully addresses the potential impacts of the final road rehabilitation designs. 3 Table of Contents EXECUTIVE SUMMARY 2 Project Summary 2 Potential Impacts 2 Conclusions 2 I.
