INTRODUCTION 1.1 Assessment Origins Shanghai is a city with a glorious revolutionary history. Many revolutionary activities have left behind precious relics and sites. While Shanghai is marching towards an international metropolis and becoming an important center of finance, economy, trading and seaport, these precious relics and sites should be protected satisfactorily as irreproducible historical and cultural recourses. The northern part of Old Hongkou takes up about 83.6ha. In this part, near Duolun Road, Shanyin Road, Liyang Road and Luxun Park, there are lanes of old Shanghai fashions, various contemporary building and precious relics and sites, which is one of the most famous historical culture sites in China as well as in Shanghai. According to the whole layout of Hongkou District, this Project-- Reconstruction of the Contemporary Buildings under Protection near Liyang Road, will pay equal attention on development and historical style and features protection to renovate the old buildings built in 1 920-30s into inimitable ones. After reconstruction through restoration and inner decoration, their dwelling functions and using values will be highly raised. The Project is located at Siping Road, Liyang Road and Baoan Road in the east; Changchun Road in the west; North Xingjiaqiao Rd in the south; 138 Lane of Baoan Road in the north with an area of about 9.36ha. Three Blocks, i.e. A, B, C blocks, are divided in this Project. The total investment is I billion yuan. It is required by the Environmental Protection Law of the People's Republic of China and Management Regulations for Construction Project Environmental Protection to implement environmental impact assessment (EIA) regulation for construction projects that may produce impacts to the environment. According to the Category List for Classifying Management of Construction Project Environmental Protection, an EIA report must be compiled for the present Project. Entrusted by Shanghai Zhongfang Housing Exchange Co., Ltd and Shanghai Hongbo Construction Engineering Co., Ltd, the SEPA-Tongji Research Institute of Environmental Protection Science and Technology, based on the principles and requirements formulated in Technical Guidelines on Environmental Impact Assessment - General Article (HJ/T 2.1 - 1993) and onsite surveying, is responsible for the environmental impact assessment on the Project of Reconstruction of the Protective Contemporary Buildings near Liyang Road.

Based on engineering analysis and analogical comparison with similar projects, to determine the characteristics of pollution sources generated in main production processes, to find major pollutants and emission amounts, and to estimate emission amounts after control measures being implemented. To predict and evaluate the impact level and extent on air quality and noise within the assessment area, during and after the construction project. To evaluate the feasibility of the environmental protection measures, and to provide control methods and suggestions for further pollution control and impact mitigation. 1.4 Scope of Assessment and Pollution Control/Environmental Protection Targets 1.4.1 Assessment Level This Project belongs to a real estate reconstruction program. After reconstruction, the [SEPA-Tongji Research Institute of Environmental Protection Science and Technology] -3 -  EA for Shanghai Hongkou District Liyang Road Old House Protection and Rehabilitation Project major water pollutant -sewerage will be disposed into the Municipal Wastewater Pipelines with daily amount of 192m3/d. There will be no remarkable noise producing sources in this Project. The acoustic environment is mainly affected by traffic noises from North Xingjiaqiao Road in south, Baoan Road in east and Changchun Road in west. According to the character, pollutant discharge amount and environmental sensitive degree in this Project, the assessment levels are determined as following: (I) Atmospheric environment According to the Engineering Analysis, the major air pollutants of the end emission of this Project are NO2 and S02, produced when food cooking and gas burning. Because the emission rate is not high and estimated emission strength is less than 2.5X 109m3/h, the atmospheric environmental impact assessment for this Project is therefore determined as Grade 3. (2) Water Environment The major items to be assessed for the sewerage of this Project are SS, NH3-N, BOD5. CODCr. The sewerage will be drained into the Liyang Road Municipal Wastewater Pipelines at the middle of this Plot and finally be treated to reach the Second Class Emission Standards by the Quyang Wastewater Treatment Plant. Therefore, the present assessment only analyzes the attainment situation of the sewerage to be disposed and as Grade 3. (3) Acoustic Environment This Project is located in a residential and commercial mixing area. According to the classification in the Environmental Noise Pollution Prevention and Control Law of the People's Republic of China, the Second Category is applicable to the present Project. Since there is no remarkable noise producing sources in this Project, the acoustic environmental assessment is determined as Grade 3. 1.4.2 Assessment Area (1) Water Environment The major pollutant is sewerage for the real estate construction project. So the assessment point of wastewater discharge is selected at the discharge outlet of this Project to enter municipal wastewater pipelines. (2) Atmospheric Environment As described, the major air pollutants of the end emission of this Project are NO2 and SO2, produced when food cooking and gas burning. Because the emission amounts is not high and have little effects on surrounding environment, the assessment area for air quality is selected as a 2 X 2 km2 area surrounding the Project site. [SEPA-Tongji Research Institute of Environmental Protection Science and Technology) -4 -  EA for Shanghai Hongkou District Liyang Road Old House Protection and Rehabilitation Project (3) Acoustic Environment The major noise pollutants are from nearby traffic noises and during the period of Project construction. Affected by the traffic noises from Xingjiabei Road in north, Baoan Road in east and Changchun Road in west, the acoustic environmental assessment is determined as the key issue and its assessment area is selected within lOOm extended from the borders of this Project. 1.4.3 Pollution Control and Environmental Protection Targets (1) The objective of water pollution control is to let the sewerage attain the emission standards of the 3rd Grade of Wastewater Synthetic Emission Standards of Shanghai (DB31/199-1997, before entering Quyang road municipal wastewater pipeline and then treated in Quyang Wastewater Treatment Plant.. (2) The objective of air pollution control is to attain the emission standards for Grade 2 (GB3095 - 1996 ) functional zone; the target of environmental protection is the community surrounding the Project. (3) The objective of noise control is to attain the Grade 2(Grade 4 beside main traffic line) in Urban Area Environmental Noise Standards (GB3096-93) and Category II standard of Industrial Enterprise Borderline Noise Standards (GB12348-90) ; the sensitive protection targets are those residents in and surrounding this Project. 1.5 Key Issues of Assessment Respective to the features of this Project and the local environmental setting, the key issues in the present assessment include: (1) Engineering analysis: (2) Existing environmental quality survey for ambient air quality and noise level; (3) Environmental impact assessment for ambient air quality and noise level; (4) Evaluation on pollution control measures and environmental cost and benefits; (5) Public survey; (6) Environmental management and monitoring. The assessment emphases are: engineering analysis, environmental impact assessment, evaluation on pollution control measures (especially on traffic noises and the exhaust gases control plan).
