PREFACE
Sino-Singapore Tianjin Eco-city is located in northern part of Tianjin Binhai New Area, between Hangu District and Tanggu District to the north of Yongding New River and to the east of Jiyun River. The project covers a total area of 34.2 km2. It’s a strategic cooperation project between the two governments of China and Singapore. Sino-Singapore Tianjin Eco-city is designed as an innovation platform of China's environment protection, energy-saving and discharge reducing, and green building technologies etc. , as an Eco-industrial base and the National-level Center of Environmental education research and development, and exhibition exchange, and the ecological industry, as a window for participating in international eco-environment development issues ,and as a livable Eco-Pilot town .
In order to implement the orientation of eco-city and implement Green Building Pilot, eco-city, on the basis of practical experience in Singapore, makes the decision to construct green building Pilot Project, including Public Housing Pilot Project and Middle School Pilot Project, where Public Housing Pilot Project will be first built soon. In addition to the role of green house model features, eco-city public housing is a non-profit policy-oriented housing, with the goal to resolve the housing problem of low-income families in the eco-city and promote the steady development of the housing market. As this project has a good Pilot effect on green building, the Global Environment Facility (GEF) grants 3.66 million dollars, and the project is required to implement the relevant provisions of the World Bank.
According to the policy requirements of Environmental Impact Assessment Law of PRC, Regulation of Environmental Protection Management of Construction Project (State Council Order No. 253), and other Chinese laws and regulations, and the World Bank OP 4.01, the green building Pilot Project in Sino-Singapore Tianjin Eco-city shall conduct an environmental impact assessment and prepare the environmental impact report. So the construction unit of this project, Tianjin Eco-City Investment and Development Co., Ltd. commissioned Environmental Planning and Assessment of Nankai University to conduct an environmental impact assessment. On the basis of data research, sector advisory and field survey, evaluators prepared a draft environmental assessment report of the project. Now submit it to environmental protection administrative departments and the World Bank to review.

1.2 EVALUATION LEVEL AND SCOPE
By the classification methods of the World Bank OP4.01 (Environmental Assessment), according to pollution characteristics，source strong，and the environmental conditions of the construction project, the project of environmental impact assessment for Public Housing Pilot of Sino-Singapore Tianjin Eco-city is classified as Class B.
The project mainly includes Public Housing Pilot Project and Middle School Pilot project，and will be construct in different stages, where Public Housing Pilot Project will be first built, which has entered into the design phase; While, the Middle School Pilot Project has less environmental impact. According to Category List of Construction Project environmental impact assessment (The Environmental Protection Department Order No. 2) ，because of the designed number of pupils and teachers，only the environmental impact registration form needs to be filled, so there is no need to conduct an environmental impact assessment. Meanwhile, in consideration that the location of public housing Pilot projects is close to middle school Pilot project, environmental impact also has similarities; the content of this report is mainly for Public Housing Pilot Project. Only in the environmental management plan, according to the characteristics of Middle School Pilot Project, propose additional recommendations of environmental management measures during operating phase.
Evaluation period includes construction phase and operation phase. Environmental impact assessment of atmosphere during construction period and operation period refer to 200m around the project. Environmental impact assessment of water achieves the sewage treatment plant of Sino-Singapore Tianjin Eco-city. Environmental impact assessment of noise during construction period refers to 200m around the project. The main considerations during operation period are that the water pump and other sound source have impact on the project itself.
1.3 EVALUATION FOCUS
According to the characteristics and the surrounding environmental conditions of the project, the assessment focuses on the environmental impact and prevention measures of dust and noises during the period of construction, and domestic sewage during operation period, environmental impact of residential garbage.
1.4 EVALUATION FACTOR
(1) Atmosphere Environment
Status evaluation factors: PM10, SO2, NO2
Prediction factors of environmental impact during construction period: TSP
Prediction factors of environmental impact during operation period: Dust, SO2, NOx, CO and THC (only accounting for emissions)
(2)Water Environment
Prediction factors of environmental impact: BOD5, CODCr, SS, NH3-N, TP (accounting for emissions and analysis of emission standards)
(3) Acoustic Environment
Status evaluation factor and prediction factor of environmental impact both are LeqdB(A).
(4) Solid Waste
Prediction factors of environmental impact during construction period: Construction waste, MSW
Prediction factors of environmental impact during operation period: MSW
1.5 EVALUATION STANDARD
The sewage of the project gets into the Ying-city sewage treatment plant and recycled water plant of Sino-Singapore Tianjin Eco-city where the sewage can be processed and recycled, and has no effect on the environmental quality of surface water. Therefore, environmental quality standards mainly refer to the atmospheric environment and acoustic environment quality standards. Among them, quality assessment of ambient air adopts the second class standard of Ambient Air Quality Standard (GB3095-1996), as shown in Table 1-1. Quality assessment of acoustic environmental adopts the second class standard of Environmental quality Standard for noise (GB3096-2008). Implement the standard for Class 4a within 30m on both sides of trunk roads, as shown in Table 1-2.

Description: The main purpose of A class room is to sleep，it is necessary to ensure a quiet room at night，this project mainly refers to residential bedroom; B class room will primarily be used in the daytime, it ensures that the spirit of thought and concentration, and speech will not be disturbed, this project mainly refers to rooms away from bedroom, and neighborhood committees and so on..
1.6 ENVIRONMENTAL SENSITIVE TARGETS
The project is located at Plot No. 15 of the Eco-city start-Area, now it is a piece of land to be built; there are no residential areas, schools, hospitals and other environmentally sensitive targets within the surrounding 300m. And as the public housing Pilot projects of Sino-Singapore Tianjin Eco-city, the project is the first construction of residential projects, during the construction process there are no residential areas, schools, hospitals and other environmentally sensitive targets within the surrounding 300m either. Therefore, this evaluation does not set the environmental sensitive targets.
