Over the last twenty years, rapid industrial expansion, population growth, and urbanization in cities, particularly since the Develop China's West initiative, have created urgent needs to develop new urban areas and to improve and upgrade existing urban and environmental infrastructure and municipal services. The urban and infrastructure constraints incities have limited cities' growth (e.g., Suining and Panzhihua) and industrial expansion (e.g., Mianyang), resulted in urban transportation bottlenecks (e.g., Panzhihua and Yibin), as well as constrained general economic development, improvements in quality o f life, and the ability to protect city residents and assets from flood hazards and environmental pollution. Municipal governments have been taking actions to address these development issues over the last five years through investment in infrastructure upgrading and developments. The proposed World Bank financed Sichuan Urban Development Project (SUDP) is designed to be integrated into and supplement locally financed efforts inthe four cities. The objective o f SUDP is to support urban renewal of the project cities to facilitate their economic development and to improve environmental conditions and quality o f life, through a mix of priority infrastructure investments in urban development, urban transport, and environmental improvement, as well as contributions to capacity building within the four municipal governments. The SUDP would also support development of new urban areas to accommodate rapid population growth and urbanization and continue attracting outside investments inindustries. Sichuan Academy o f Environmental Sciences (SCES) and Chengdu Hydropower Investigation & Research Insitutute (CHIRI) have been engaged to conduct the environmental assessment (EA) for SUDP. Each o f the EA teams are responsible for two cities: Mianyang and Suining by SCES, andPanzhihua and Yibin by CHIRI, respectively. The EA is to identify potential environmental benefits and consequences o f the project, propose measuresto avoid, mitigate or otherwise compensate for negative environmental impacts during construction and operation, and allow incorporation o f appropriate measures into the design to minimize negative impacts to an acceptable level. This document is a summary o f the EA documentation, compiled based on the four city EIA reports and four EMPs. 1.2 Basisfor the EA The legal and technical basis for the EAis: Environmental Protection Laws o f PRC (December, 1989); and other state laws and Chengdu Hydropower Investigation Design and ResearchInstitute 4 SichuanAcademy of Environmental Sciences  Sichuan Urban Develoument Proiect EA SummumReuort regulations for water, air, soil, ocean, and solid waste pollution control; General City Plans of Mianyang, Panzhihua, Suining,Yibin (2001-2020); Tenth Five Year Plans for Environmental Protection for Mianyang, Panzhihua, Suining, and Yibin (2001-2005); 0 Terms of Reference (TOR) for Environmental Impact Assessment for Sichuan UrbanDevelopmentProject (May 2005); Notice on Strengthening Management on Environmental Assessment for Construction Projects funded by International Financial Organizations, NEPA, SPC, the Ministry Financeandthe People's Bank of China, No. [1993]324; Operational Policies, Bank Procedure and Good Practices OP/BP/GP4.01: Environment Assessment, the World Bank, (January, 1999) and other safeguard policies where they are applicable; and 0 Feasibility study reports for the Mianyang, Panzhihua and Suining components by Southwest Municipal Design and Research Institute and for the Yibin components by ChengduMunicipal Engineering DesignInstitute, respectively. The environmentalquality anddischarge standards appliedinthis EA are determinedbasedon the functions, the impacted areas and as designated by relevant environmental authorities. These standards are: Surface Water Quality Standards, Class I11for the project arearivers; Ambient Air Quality, Class I1for project areas; Noise Standards, Class Ifor the most sensitive receptors such as hospitals and schools, Class I1 other sensitive receptors such as residents and Class I V for areas adjacent to trunk roads; 0 Wastewater Discharge Standards, Class ICategoryB; Construction Standardof UrbanWastewater Treatment Project; and 0 IdentificationStandard for Hazardous Wastes for river sediment. 2. Project Description The SUDP includes area development, sewer line construction, flood control through river embankment, road development and environmental improvement components in four secondary cities in Sichuan province. These components are summarized in Table 2-1 through Table 2-4 Chengdu Hydropower Investigation Design and ResearchInstitute 5 SichuanAcademy ofEnvironmenta1 Sciences  Sichuan Urban DevelopmentProject EA Summary Report Table2-1 MainComDonentsof MianvangProiect I Item I Contents Scale I 22 road sections II 21.23 km long; 9-50 mwide I Pioneer Park Storm and sanitary sewers 91.79 km 1 interchange and 1 flyover Lighting and traffic management system Along the roads Economic 17 road sections 24.53 km long; 14-80 mwide Development Storm and sanitary sewers 74.56 km Zone 1interchange, 4 flyovers Flood control embankment 4600 m Table 2-2 Main Comr>onentsof Panzhihua Proiect Item Contents Scales I Embankment Bankenforcement andupgrading Totaling 85.54 km River sideroad I New roads I 2.68 km I Bridge 0.93 km Landscaping Lawns andscenery Along the river side Sanitarv sewer Sewer pipeline 38.9 km Item Contents Scales Roads 3 segment upgrading and 19 new roads Total 35.68 km Bridges 9 new bridges Total 288 m River rehabilitation Expandinddredginglembankment 4.73 km Sanitary sewer pipe D300-800 pipes, 3 mbelow new roads 21 km Storm sewer DiDe D400-800,2 mbelow grade along new roads 21 km Item Contents Scales Road LineA Road 6.9 km Bridgeand culvert 10 units Embankment 2910 m Landscaping Along the river Road Line B Road 3.5 km Embankment 3521 m Landscaping Along the river The specific component locations are shown inFigures 2-1 through 2-4.

EnvironmentalBaseline 3.1 GeographicPosition Mianyang, Suining and Yibin are to the north, east, and southeast of the Sichuan basin while Panzhihua is inthe deep mountains at the SichuadYunan provincial border (Figure 1-1). More specific locations of the four cities are presentedinTable 3-1. The project area topography is basically plain to mild undulation inMianyang, Suining and Yibin but high mountains and deep valleys inPanzhihua.
