1. General Introduction
To strengthen the infrastructure construction, improve the heating service quality, solve the regional environmental pollution problem and increase people’s living standard, Liaoning Provincial Government is planning to enhance the infrastructure construction under the Third Liaoning Medium Cities Infrastructure Project (LMC3) to be partially financed by the World Bank. This project has been included in the Chinese Government program for utilizing the loan from World Bank in 2006. The project includes construction of district heating infrastructure works in 6 cities such as Anshan, Fushun, Benxi, Liaoyang, Yingkou and Huludao. Totally included are 11 sub-projects after the primary screening and identification. The total investment of this project is about 2,79945 billion RMB Yuan, equivalent to USD 373,26million, of which187 million US dollars will be from the World Bank, and the rest will be covered by the local governments .

1.1 Project Background
1.1.1 Relevant policies of Liaoning Province
Liaoning Provincial Government has been supportive of the application for the World Bank loan which will be used for funding the sub-projects. A coordination group for the implementation of LMC3 to use the World Bank loan has been organized by the General Office of Liaoning Provincial People’s Government, which is primarily in charge of examining and determining the master plan, organizing and coordinating the implementation of initiatives to address key problems encountered in the development of policies, and institutions. The group consists of representatives from Liaoning Provincial Government, Financial Department of Liaoning Province, Liaoning Provincial Environmental Protection Bureau, Construction Department of Liaoning Province, Liaoning Provincial Price Bureau, Development and Reform Commission of Liaoning Province, Price Control Administration of Liaoning Province, Department of Audit of Liaoning Province, the Land and Resources Department of Liaoning Province. The Office of Utilizing the Foreign Capital and Urban Construction is in charge of the daily management under the leadership of the coordination group.

(Hai
cheng) / Central Heating Project in the North of Yong’an Road Tiedong District Haicheng City / （1）A Large number of scattered small boiler rooms with small capacity, low heating efficiency, serious energy loss and environmental pollution, excessive working loads for operators.
（2）Most of the boiler are running under overload without meeting heating supply requirements. The number of houses with an indoor temperature ranging from 10 to 14℃ within the service area accounts for 30% of the total.
（3）Too simple smoke and dust removal equipment, absent of desulphurization devices, severe environmental pollution; piping network out of repair, water loss rate up to 4%～8%; the pipelines are elevated over the urban districts in some cities, which cause passive impact on the landscape..
（4）the service areas are not reasonably planned, leading to overlapping of the service area to be serviced by different plants.
（5）Numerous of small heating enterprises with poor management and service.

situation of gas supply / Ying
kou / Rehabilitation and Expansion Project for Gas Facilities of Yingkou City / （1）Natural gas pipelines are not well repaired and maintained for the past 30 years. Particularly after the impressed current cathodic protection system for the pipeline were removed in 1990’, the degradation of the pipelines has be enhanced, which leads to a serious leakage of the gas. In some are, the pipeline can merely transmit the gas under low pressure, which consequently neither meet the requirement of gas transfusion nor reduce the operational cost.
（2） There are two wet gas storage tank with the capacity of 20,000 m3 and 50,000 m3 respectively, which were put in use in 1989 and 1995 without any overhaul in the gas source plant.
（3）The medium pressure pipeline in Yingkou city has been operating for over 10 years, and the mechanical flexible joints on some sections have get loose with slight leakage. The consequence would be disastrous if the gas spreads to the building or the sewers. In addition, with the constant expansion of urban area, occupation of the buried pipeline by other structures and buried depth changes can be found everywhere. The valve well on the pipeline, and most of the condense cylinders are damaged to various degree.
（4）Besides, Yingkou city is located in Liaohe estuary with low-lying terrain, high acidity and alkalinity and serious chemical and electro-chemical corrosion in some parts. With too limited corrosion proof method, and shortage of electro-chemical countermeasures, auxiliary facilities such as the condense cylinders are being damaged at a rather fast speed, resulting in the increased management cost and safety risks.
1.1.2 Heating and Gas Supply Situation and Problems in Central Cities of Liaoning Province
Cities applying for the loan from the World Bank are Anshan, Fushun, Benxi, Liaoyang, Yingkou and Huludao. At present, problems such as plenty of small boiler houses, poor heating quality and serious environmental pollution, aged gas supply systems without repair exist in all cities. Please refer to the environmental management plans of all sub-projects for details.
1.1.3 EA Category
According to the World Bank’s safeguard policy, Environmental Assessment OP4.01, this project has been classified into Category B, as it has short construction period, mature and reliable technique, controllable pollutants discharge and the confined scale of environmental impact.
Notice of the General Office of the SDRC of Certain Issues Regarding Handling Confirmation for Debt from International Financial Organizations and Foreign Governments
In accordance with the Notification on Strengthening the Supervision of Environmental Impact Assessment of the Projects Funded by Loans from International Financial Institutions (No. 324) [1993] promulgated by State Environmental Protection Administration, State Planning Commission, Ministry of Finance and The People’s Bank of China in June 1993, the adverse environmental impact from this project is less than that from category A project, and can only act on the work site, which can be reversed in most cases. With the effective relief measures on environmental impact, waste gas pollutants emitted from this project have conformed to the regulations of Emission Standard for Air Pollutants from Boilers （GB13271-2001）and Integrated Emission Standard of Air Pollutants （GB16297-1996）; waste water pollutants discharge have conformed to the Integrated wastewater discharge standard （GB8978-1996）and Liaoning Local Standard on Discharge of Wastewater and Exhaust Gases（DB21-60-89）; Solid wastes have been utilized and disposed in a multipurpose and orderly way, forbidden to discharge. By doing this, both the degree and scope of the impact from this project will be restrictive.
