It is one of the three main sections of "The National Artery Highway Configuration Planning"approved by the state council. The total length of the proposed highway is 237.588km, including 140.733kmof expressway, 97.182km of class-two highway. The total estimated cost is 4,117,000,000 RMB yuan with inclusion of 1,660,000,000RMB yuan of the WorldBank Loan. In recent years, the regional economy in the study section grows rapidly and commodities in inland provinces of Southwest are put into the world markets more and more through seaports. In addition,the poorer regions in the northwest of Guangxi need to get rid of poverty and become rich. However,the existing Shui-Nan Highway is operating well below an acceptable level of service for the above mentioned purposes. Therefore, a new high class highway is urgently needed. Wuming, Mashan, Duan and other counties require that the proposed highway pass through their territories to bring the advantages of the fast efficient and comfortable high class highway into full play. The projected highway will also promote the regionaleconomy to overcomepoverty and get better off. In July 1993, Xian Highway University, entrusted by Guangxi Communication Division (GCD) compiled the EIA of the project. In August and September 1996, the EIA panel made the first field reconnaissance and survey and collected the data concemed, based on which the outline of EIA was compiled. In June 1997, the assessment center of the State EnvironmentalProtection Administration (SEPA) evaluated the outline from technology perspective. Afterwards, a reply on the review of the outline from the SEPA was received.In September 1998, the IdentificationMission of the World Bank offered technical guidance about the outline of EIA. In the same month, the panel made the second survey and investigation. Late November, 1998, the panel of assessment,based on the commentsof the specialists of the Bank, introducedthe outline of the EIS to the public along the study area, pointing out the major potential impacts of the construction on the environment,and also had the hearings of the public, and based on it the panel worked out the EIA. Early December, 1998, the EnvironmentalProtection Agency of the MOC held a prereview meeting on the EIA in Nanning. In the end of December, 1998, the panel made an introduction to the EIA to the public in the areas affected by the proposed project. As a result, the public concerned was informedof the mitigative measures as well as the potential impacts resulting fiom the projected highway. After collected the opinions from the masses again, and based on the co,mmentsof the specialists of the prereview meeting and the new edition of the "Project Feasibility Study Report of the HechiFJ(Shuiren)ODuanONanningHighway" of Dec. 1998, the panel of EIA completed the Statement of EIA (Edition for Review & Approval)in January, 1999 to submit to the State Environmental Protection Bureau and the World Bank for examination. In March and August, 1999, We have received some good recommendations in contents from The World Bank EP experts before our new revision. We have had generous help from various departments or local govemments for which we express our genuine thanks. (g£) . ..
