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.

It is one of the economical functional regions that will mainly develop in the future, viz. the organic constituent of the functional region which included Sichuanbei Road-Duolun Road-Hongkou soccer stadium. 3.1.2 Topography and River Several riverway such as the branches of Huangpu River(Yujingpu, Shajing port, Hongkou port) wander across Hongkou District making up of the advantaged natural resource. The river system of Hongkou port is the maternal river of Hongkou. It is 21.6km long and 376500 m2 wide within the district and comes across throughout the nine streets and the one town in the whole district. At the same time, it is the main channel taking up the task of flood prevention and waterlog exclusion in Hongkou, Zhabei and Baoshan district. The cut-current project in two port was started-up completely last year. The rain-sewage [SEPA-Tongji Research Institute of Environmental Protection Science and Technology] -17 - EA for Shanghai Hongkou District Liyang Road Old House Protection and Rehabilitation Project combination pumping station was built in Hengbang and Huachang and silt which were about 350000m3 were dredged up in the Riverways. 2100t floats were dredged and this made Hongkou port had almost no floats. The survey of water pollution source was also put forward at the same time. The water quality in the whole water system was improved obviously and eliminated black and odour. Now the water quality is between 3-D according to the surface water environment quality standard. 3.1.3 Climate and Weather Located in middle latitude zone to the east bank of Eurasia Shanghai city is extrusive part of the seaside in eastern china.

It is about 23.48km2 wide and has permanent population about 860,000 along with floating population about 140,000. There are 9 streets and one town in the district. The foundation of historical culture in Hongkou is profound. There are 72 literal sights in the district. Around Luxun park and Shanyin Road seated former residences of the top ten culture celebrities Luxun, Guo moruo, Maodun, Dingling etc. in modem times, art gallery of Zhu jiuzhan, memorial of the five left-union marties and memorial of martyr Limai. Hongkou stadium that was rebuilt from Hongkou palaestra 46 years old becomes the one and only specialty soccer stadium. The integrity functions including shopping, traveling, compete, entertainment and life fallow are emerged step by step owning to the stadium linking with Sichuanbei Road and Duolun Road. Many buildings of latter-day internal or external in different style distribute along the sides of Duolun Road which is 500m long. The road is developing primarily to be a characteristic culture and celebrity one famous for "past lane in Shanghai, former residence of celebrity, street market of culture relic, community for life fallow". Hongkou district always lists in front of central district in Shanghai regarding the economic construct as the central task, insisting on deepen the reform, widening open both to inner and outer. Integrete economy strengths boost up notably. Finance income of the district arrived at 1.710 billion yuan, increasing 20.4% lFoL Industry in Hongkou developes quickly and forms the urban industry pattern mainly about chest and bag, costume, lamps and lanterns, automobile fittings, processing to bullion accouterment. Sichuanbei Road that is 3.7km long has been one of the most flourishing shopping center and most attractive entertainment district in Shanghai. There are more than 40 specialty market in the region such as the famous market Quyang domestic electric [SEPA-Tongji Research Institute of Environmental Protection Science and Technology] -20 - EA for Shanghai Hongkou District Liyang Road Old House Protection and Rehabilitation Project apparatus center and Shanghai lamps mall. Based on Shanghai commerce center, Dabaishu trade region is actively in exchange of manufacture materials. There are 25 different specialty market and bargain amount is more than 15 billion yuan per year. Seven foreingn trade company such as Shanghai craftwork imports and exports company and Shanghai textile imports and exports company locate along Wusong Road and Siping Road. Zhapu Road is famous for its cate street. Recently, Hongkou district government endeavors in building the publicity, impartiality and righteous market environment for all kinds of enterprises by optimizing invest environment, improving government work efficiency and perfecting policies. These acts made rapid progress in the district. Inner invest enterprises about 2952 were introduced into in 2001 increasing 61.9% compared with the same time in history. The register capital is 3.11 billion yuan increasing 18.1% compared with the same time in history. About 46 foreign capital items were authorized the whole year with increasing about 53.3%. Hongkou is one of the large education district in Shanghai. There are several famous schools such as Fuxing middle school, the first affiliated middle school of East China Normal University and Beijiao middle school etc. There also famous university such as Shanghai Foreign Language University and Shanghai Financial University. Hongkou is the only one culture old district that was granted national culture model district. It has bring up many super athletes for the nation and Shanghai. Hongkou was entitled home of swim and home of Wushu. Facing with the challenging new century that is full of chance, Hongkou is planed to be a modern district corresponding with Shanghai city by building prosperous commerce and shopping region, comfortable inhabitation, advanced culture and education district during the tenth five year 3.3 Compatibility of project implement 3.3.1 Programming function of the region related to the project This project locates in north part of the former Hongkou. The region is one of integrate service center in Shanghai and is the main part of public service and activity center in Hongkou. It is a multifunctional district with culture life fallow, sightseeing and traveling, commerce and food service. At the same time it is the characteristic region organic combining the history with present and integrated service with middle and top grade inhabitation. [SEPA-Tongji Research Institute of Environmental Protection Science and Technology] -21 - EA for Shanghai Hongkou District Liyang Road Old House Protection and Rehabilitation Project According to the general programming to north part of former Hongkou, Shanyin Road and Liyang Road are mainly functioned as inhabitation and keep intact historic style and space overall arragement. Lots of lanes in different style of different periods and many independent and coexistence garden style house were preserved and should act as the exposition of modem time house in Shanghai. The develop tactic in this region focus on combining preservation and repair. Improve the inhabitancy environment based on preserving and continuing the existing pattern and historical style. Aims to make it a characteristic top grade inhabitation region mainly functioning as dwell giving attention to culture and service industry at the same time. 3.3.2 Analysis on compatibility of environment programming There is no industry pollution source around the project and uptowns and public establishments that had already built locate nearby. The old buildings in the east of Baoan Road are being removed and rebilt. The reconstruction and protection of the latter-day buildings in Liyang Road is on the premise of preserving the primary construction style and the view of the community. The disordered buildings will be removed in order to improve environmental quality and increase the green ratio. In a word, the project is compatible with both surrounding environment and programming. 3.3.3 Partition to environmental functions of the region related to the project The air environment is in the range of 2nd grade and the noise environment is in the range of 2nd urban noise grade.

Flue will diffusion from top of the buildings through exhaust canal in buildings after purified by flue-exhauster. (3) Solid waste Living solid waste will be up to 480 kg/d. They will be put in bags and collected in 12 garbage boxes set beside roads then sent to transfer station. 4.2 Waste water drainage and analysis of its control steps (I) Estimate to the amount of water supply and drainage The amount of water supply and drainage is 364.4 t/d and 252.1 t/d respectively. They are listed in table 2-3. [SEPA-Tongji Research Institute of Environmental Protection Science and Technology] -24 - EA for Shanghai Hongkou District Liyang Road Old House Protection and Rehabilitation Project (2) Waste water drainage amount and qulity Concentration and amount of pollutants in drainage are listed in table 4-3. The drainage amount of waster water is 252.1 t/d and pollutants such as CODCr, BOD5s NH3-N, SS, propagation oil is75.6, 37.8, 6.3, 88.2, 7.6kg/d respectively. (3) Sewage management steps Living sewage produced by dwelling house public building will tally with the third class diffusion standard of Shanghai after collection and sent to municipal sewage pipeline in Liyang. At last it will go to Quyang water quality purify factory and drainage to water body in city after reaching drainage standard. (4) Feasibility analysis of sewage canal Sewage can not let liberty restricted by sewage quality and construction status of surrounding sewage pipeline. It must ensure that sewage be treated effectively without letting to the freshwater riverway directly. Currently the living sewage let in pipeline directly and sent to Quyang water quality purify factory. Living sewage amount will decrease after rebuilt and water quality will be improved because some offices in the region would move away and living habitual of tenements would change. At the same time the sewage let to municipal pipeline through district sewage pipeline will be treated efficiently in Quyang water quality purify factory. Since the situation provide objective conditions for pipeline the exploiter should apply to related government department for draining water to the municipal sewage pipeline directly. Compared the two treatment methods the sewage pipeline has less influence to surrounding environment. It helps alleviating fume diffusion from sewage treatment station and solving the problem of residual sludge treatment. Furthermore, from the point of view of engineer economy it is more reasonable of treating centralize than separately. 4.3 Waste gas diffusion and analysis of its control steps Waste gas from kitchen Natural gas is used in kitchens in this region. The most amount consumed in city is 200m3 /hr, average at about 100 m3 /hr. Diffusion amount is estimated in the basis of 12.8 kg NO,(in which, 6.3 kg NO2). 1.0 kg SO2, 2.4 kg flue being diffused with burning 104 m3 gas( diffusion parameter is cited from Environment Practical Data Handbook). Pollutants produced by burning gas are listed in table 4-4.

Living garbage mainly come from kitchen and other living ways. The produce amount of living garbage is about l.Okg/d.p based on present living standard of Shanghai and statistical data recent years. There are 96 tenements in the region and about 480 residents in the premise of 5 person every tenement. Garbage amount calculate based on this situation is listed in table 4-5. Components of living garbage are listed in table 4-6.

(2) Analysis of solid waste treatment According to the set principle of solid waste management ordinance the waste produced by the project is living garbage and belongs to common solid waste. [SEPA-Tongji Research Institute of Environmental Protection Science and Technology] -26 - EA for Shanghai Hongkou District Liyang Road Old House Protection and Rehabilitation Project The amount of solid waste produced by residents after the project finished is 182.5 t/a based on the engineer analysis. Living solid waste will be put in bags and collected in 12 garbage boxes set beside roads then sent to transfer station at Baoan road and treated together by environment protect department. 4.5 Analysis of main surrounding pollution source 4.5.1 Main waste gas pollution source There is no industry waste gas pollution source around the project. The gas source is tail gas from Xingjiaqiaobei Road in the north, Liyang Road across mid-part of the region, Baoan Road in the east and Changchun Road in the west of the region. Among these places, Baoan and Changchun Road are so narrow and so many stalls and simple buildings distribute alongside the pavements that people have to walk on the drive-lane. This makes the traffic is heavy so the tail gas pollution of automobiles is serious. Liyang Road will rebuild to be the interior street in the community and it will help reducing vehicle flux greatly resulting in alleviating pollution. But with the degenerating of traffic function of Liyang Road will certainly increase the vehicle flux in the other three streets. They will be the main pollution resource in the future. Sichuanbei Road locates 40m to the west of Changchun Road which is the west boundary of the region and is almost parallel with it. Siping Road locates 50m to the east of Baoan Road and Liyang Road which are the east boundary of the region and is almost parallel with them. Because these two streets being the main traffic artery in north-south direction, the vehicle tail gas has some influence in the project. But the influence is not so great for the streets are kept away by buildings from the community. 4.5.2 Noise source At present, the main noise source comes from traffic in Liyang Road, Xingjiaqiaobei Road and Changchun Road. It will come from Xingjiaqiaobei Road and Changchun Road and Baoan Road after the rebuild being finished. The nearest distance from Xingjiaqiaobei Road to the north part of the project is about 24m. The traffic flux will increase as a result of widening the street and it will influence residents in the north part greatly. Changchun Road and Baoan Road is close to boundary of the community and they will take the traffic pressure breakaway from Liyang Road after rebuild. This part of the region will still be influenced by the noise regardless of putting up with greenbelt between the buildings and streets. [SEPA-Tongji Research Institute of Environmental Protection Science and Technology] -27 - EA for Shanghai Hongkou District Liyang Road Old House Protection and Rehabilitation Project 4.6 Environment analysis of plane arrangement In view of architecture arrangement this project pays much attention to architecture arrangement and environmental sight design. Greenbelt, racket court, waterscape and club are built centralized in the community. Greenbelt ratio reaches 60%. Various dwelling houses distribute properly in the community. All these establishments provide comfortable and convenient dwelling environment. The dwelling houses are kept away from surrounding streets that produce great noise by greenbelt. This has some effects to the residents dwell along the streets but the effects are not in evidence because of the restrict of former construct arrangement. Circular pump in the water area is going to use submersible pump. It is anticipated that circulate noise would not affect residents nearby. Since the garbage boxes being arranged in greenbelt besides roads in the community and the garbage being collected and transferred on schedule, they will have almost no influence to residents and sight. Analyses in general the plane arrangements of the project have no serious environment problems except traffic noise. Suggestion: Because the project is oriented to be a top grade uptown so the doors and windows in all rooms should be sound insulation. In order to cut down the influence to residents at the best, signs of no-homing and speed-limiting at I5km should be set in the community.

The argumentation of the countermeasure to control pollution in the operating period 9.1 The commentary of the countermeasure for pollution control In the project, the water, electricity and coal gas were switched in through municipal pipeline. The mainly sewage is domestic discharges. The sewage was brought into municipal waste pipe through the pipe in the block and was treated in the Quyang effluent plant finally. There are not underground parking lots, transformer substation and fan facilities house in the community. So the countermeasure to control pollution is seldom took into account. In the design at present, the disposal of the domestic waste is mainly considered. It is planned to setup some waste collection point. The different domestic waste will be classified and collected by bags and piled in different garbage bins respectively. The waste in garbage bins was transported to the collection point by the realty management staff everyday and was disposed by the environmental sanitation department. The waste in the community will be cleaned up everyday. 9.2 The measures for farther pollution control The mainly environmental problem of the project is the traffic noise pollution from the circumjacent roads such as Liyang road, Changchun road, Siping road and Xingjiaqiao north road. The measures as follows is planned to adopted to settle these questions. (I) Only the dillies can pass through the Liyang road which past across the middle of the community and the heavy traffics' passing is forbidden. To install conspicuous hooting forbidden sign at the road section which pass the community can alleviate the influence of noise to the residents in the community. (2) When designed, sufficient frontage of the first row of the building would be left beforehand to landscaping or build earth slope. It can beautify the community and ameliorate the environment by reducing noise. (3) The windows and doors of the houses facing the street should adopt the sound insulation measure.

[SEPA-Tongji Research Institute of Environmental Protection Science and Technology] -60 - EA for Shanghai Hongkou District Liyang Road Old House Protection and Rehabilitation Project 9.3 The environment profit and loss analysis Fixing the sound insulation windows and doors on the first row of the building near the Xingjiaqiao north road, Changchun road. Bao'an road and Liyang road will increase the investment for about Y300,000. Furthermore, the landscaping and construction of waterscape need more investment too. [SEPA-Tongji Research Institute of Environmental Protection Science and Technology) -61 - EA for Shanghai Hongkou District Liyang Road Old Flouse Protection and Rehabilitation Project 10. Conclusions and Suggestions 10.1 Main Conclusions I.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 1920-30s 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 Road 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. 2 The Project covers total construction area of about 94430m , among which Block A of 56190.3m2, Block B of 16806.5 m 2and Block C of 14859.5 m 2. The assorted public facilities area is about nm and the capacity rati. is 0.36 with total investment of I billion yuan. This project locates in north part of the former Hongkou. The region is one of integrate service center in Shanghai and is the main part of public service and activity center in Hongkou. It is a multifunctional district with culture life fallow, sightseeing and traveling, commerce and food service. At the same time it is the characteristic region organic combining the history with present and integrated service with middle and top grade inhabitation. The reconstruction and the Protection is on the premise of preserving the primary construction style and the view of the community. The disordered buildings will be removed in order to improve environmental quality and increase the green ratio. In a word, the project is compatible with both surrounding environment and programming. 2. The latest monitoring data of air quality were collected from the Environmental Protection Monitoring Station near the project. It is shown that the hourly concentration ranges, daily average concentrations and percentages beyond standard of SO2 and NO2 are all under the assessment criterion while those of PM1o changed a lot and the percentage beyond standard is 40%. In general, the ambient air quality in assessment area is fine. Because east ,south, west, and middle of the plot affected by traffic noise of Liyang and Baoan Road, North North Xingjiaqiao Road, Changchun Road, and Liyang Road respectively, the existing environmental quality of this Plot is worse than the assessment standards, especially at night except site 1 which is not affected by surrounding traffic noises.. [SEPA-Tongji Research Institute of Environmental Protection Science and Technology] -62 - EA for Shanghai Hongkou District Liyang Road Old House Protection and Rehabilitation Project 3. The water source will be not changed after reconstruction and the tap water will be taken in from the municipal tap pipeline under the Liyang Road at middle of the Plot. Now the water consumption amount isl364m3/d and discharge amount is 1091.2m3/d. After reconstruction, the maximum water consumption amount will be 364.4m3/d.The drainage amount of waste water of this project is 252.1 t/d and pollutants such as CODcr BOD5, NH3-N, SS, propagation oil is75.6. 37.& 6.3. 88.2 7.6kg/d respectively. Living sewage produced by dwelling house public building will tally with the third class diffusion standard of Shanghai after collection and sent to municipal sewage pipeline in Liyang. According regulations referred to environmental protection on Shanghai, sewage will go to Quyang water quality purify factory at last. 4. The noisy sources around the project are mainly from nearby traffic noise. According to the existing monitoring and prediction results, Relatively great effects are from Liyang Road and Baoan Road at the east, North Xingjiaqiao Road at the south, Changchun Road at the west and Liyang Road at the middle of the community. After reconstruction, only mini cars can pass through the Liyang Road which past across the middle of the community and the heavy traffics' passing is forbidden, which is benefit to the sound environment inside the community. The buildings next to North Xingjiaqiao Rd is rather affected by traffic noise and so necessary noise protection measures must be applied. 5. The impact of automotive emissions is acceptable, and the environmental air quality will be still under the standard. Moreover, the route of the No. 47, 592 and 863 buses, which pass the single-way Liyang road every day, are going to be changed for the reconstruction project. As the result, only small vehicles will be allowed on Liyang road in the future, which will obviously improve the environmental air quality in this community. 6. The amount of solid waste produced by residents after the project finished is 182.5 t/a. Living solid waste will be put in bags and collected in 12 garbage boxes set beside roads then sent to transfer station at Baoan road and treated together by environment protect department. 7.The waterscape in this Project should meet the standards of GradeVin "Surface Water Environment Quality Standard". To avoid water quality deterioration, a water pump system will be adopted to make water recycle flowing while fountains are set to supplement oxygen into water. Forbidden to throw and no wastewater enter into the water through rain pipes by strengthening management measures. 8.The comprehensive score of ecological suitability is 84, corresponding to high quality housing area and near the villa area, indicating that the Project has good ecological suitability. indicating that the Project has good ecological suitability. [SEPA-Tongji Research Institute of Environmental Protection Science and Technology] -63 - EA for Shanghai Hongkou District Liyang Road Old House Protection and Rehabilitation Project The development of real estate can promote the development of commerce as well as the development of local economy. Above all, this Project is acceptable. 10.2 Suggestions 1. The restaurant in the business building should be arranged in direction of downwind of the main wind direction. 2. After reconstruction, only mini cars can pass through the Liyang Road which past across the middle of the community and the heavy traffics' passing is forbidden. And conspicuous "No homing " signs will be set on the nearby road section. This will reduce the impact on the residents in this Project. When designed, sufficient frontage of the first row of the building would be left beforehand to landscaping or build earth slope. It can beautify the community and ameliorate the environment by reducing noise. 3. The windows and doors of the houses facing the street should adopt the sound insulation measure. The chamber facing the street can't be designed as bedroom. It will be only used as accessorial chamber. 4. Homing is forbidden when the vehicles pass in and out the community. The speed of the vehicles passing through the community is governed. [SEPA-Tongji Research Institute of Environmental Protection Science and Technology] -64 -
