As seen from the above table, the air monitoring average value per day of monitoring sites satisfies the Class2 standard (GB3095-1996), therefore, the urban air quality in Shuangfeng County is rated as good. III. Current Sound Environmental Quality Shuangfeng County Environmental Monitoring Station set up 100 routine sound monitoring sites in the urban area, and for the sound monitoring statistics results of monitoring sites nearby the affected areas by the construction, please see Table 3-4.

As seen from the above table, the equivalent sound levels of the routine sound monitoring sites in the urban area of Shuangfeng County mostly exceed the standard value, and the traffic sound is the main cause resulting in over-standard sound in monitoring sites. IV. Original Pollution and Main Environmental Problems Related to the Project i. Major Industrial Pollution Sources

It’s known from the investigation that the industrial pollution in Shuangfeng County mainly sources from Fenghua Industrial Co., Ltd. And Metallurgy Machinery Co., Ltd., both of which mainly emit sound and soot, basically no sewage.

ii. Major Domestic Pollution Sources

It’s known from the investigation that there are concentrated pollution sources with big sewage discharge per year in Shuangfeng Urban Ceshui River reach including People’s Hospital, Hospital of TCM and Shuangfeng Hotel, which have the sewage emitted to Ceshui River. In addition, the most of the domestic sewage for the urban residents is directly emitted into Ceshui and Mishui River, thus resulting in certain pollution on the two rivers. The main pollution genes in the domestic sewage in the urban area are total nitrogen, total phosphorus, COD, BOD5 and Faecal coliform group. iii. Major Environmental Problems A. Pollution on water quality of Ceshui and Mishui River by city sewage discharge The urban sewage in Shuangfeng County is mainly domestic sewage, due to no sewage treatment plant in the urban area, the urban sewage is directly emitted into the downstream of Ceshui and Mishui River without complete treatment, therefore, it is the direct factor to result in the water quality problem of Ceshui and Mishui River Urban Section. Owing to the impact by the emitted domestic sewage, the Ammonia and Nitrogen, hypermanganate and five-daybiochemical oxygen demand indices occasionally at the section of Mishui Waterworks are occasionally over standard. The water quality in the river reaches nearby the urban area has been polluted to an extent. B. Urban garbage problems At the two banks of the Chengzhong River in the urban area and partial Ceshui River reaches, there are a lot of garbage stockpiling there. The residents, units and industrial and commercial enterprises at the two banks dump domestic and construction garbage randomly, which affect water flowing from the riverway and the beauty of the urban area; in addition, in flood season, the garbage is washed into Ceshui River to affect the water quality of Ceshui River. C. Flood disasters The urban area of Shuangfeng County is located at the two banks of Ceshui and Mishui Rivers, however, the Ceshui and Mishui River Urban Section, currently, has no any flood control works with riverway flood control capability lower than 10-year-occurrence. Once it meets with the downfall, the lowlands at the two banks of Mishui and Ceshui River Urban Section shall suffer the attack of flood. Especially in the recent years, the annual rainfall was quite abundant, the urban area almost has suffered the flood disaster each year. The domestic sewage and the industrial sewage and waste water emitted from the urban are directly drained into Ceshui River by the Chengzhong River in River West and the Chengdong River in River East, once it rains in flood season each year, the water level of Ceshui River is high, the rainwater, sewage and waste water in the urban cannot be drained into the river, therefore resulting in the urban area in River East and West

Project Analysis

Construction Period of Project I. Construction Process The environment will be affected by Shuangfeng urban flood control project mainly in the construction period. Such construction activities as foundation excavation, transportation by vehicle, land occupied by structures, and waste slag will affect the environment. The construction process is as follows:

i) Flood Embankments: Earth excavation —— soil transportation —— filling of flood embankment —— mortar rubble protection slope —— sodding protection ii) Wave Walls: Form erection by workers —— concrete mix —— concrete transportation —— concrete placement —— concrete curing. iii) Sluices: Earth excavation —— foundation treatment —— concrete mix —— concrete transportation —— concrete placement —— concrete curing. iv) Pump Stations: Foundation excavation —— concrete mix —— concrete transportation —— concrete placement —— concrete curing v) Waste: The unusable material from foundation excavation and house demolishment —— transportation by vehicles —— deposit at spoil sites—— measures for water and soil conservancy II. Main Pollution Process The process of main pollutions during the construction of Shuangfeng urban flood control project is given below: i) The foundation earth excavation for flood embankments, electric drainage stations, sluices, and pump stations, the earth excavation at borrow area, the waste stockpile at spoil site, and the construction of body of flood embankment will generate such unfavorable impacts on environment as the noise, dust, dust emission, tail gas of fuel, leakage of oil stain and loss of water and soil. ii) The exploitation, rinsing and screening of sandy gravel, the precasting of concrete for protection slope of flood embankment, the concrete placement in wave walls, sluices and pump stations, and the curing will generate the noise, dust and wastewater. iii) Such construction processes as the exploitation of borrow area, the waste deposit at spoil site, the waste and material, and the transportation of building materials will generate the noise, dust, dust emission, and water and soil loss. iv) The domestic garbage, sewage and hidden danger to human healthy will be generated in the temporary residential area of construction personnel in construction period. Resettlement Process A total of 362.3mu permanent land will be occupied by Shuangfeng urban flood control project, including 72.3mu of paddy field, 44.2mu dryland, 15.7mu vegetable plot, 1.9mu of fish pond, 24.8mu of rural hosing plot, 1.5mu of residential land, and 201.9mu of flood land. A total of 9 villages, namely Hetang Residential Committee, Wenxing Residential Committee, Hongqi Village, Hengtang Village, Maoping Village, Litou Village, Jingwan Village, Yuanxiao Village and Jingping Village in Yongfeng Town. Additionally, 461 persons form 139 households will be relocated, who need houses of 16014.1m2. No concentrated resettlement sites will be proposed for resettlement, the affected persons will be resettled in their existing village. 461 persons will be relocated by economic rehabilitation and adjusting farmland in the village groups. Since many people will be affected by the

Hunan Hydro and Power Design Institute 16 Environmental Assessment Report Table of Shuangfeng County Urban Flood Control Project

Shuangfeng urban flood control project and large area of houses shall be demolished, so the house construction and economic rehabilitation will bring inconvenience to the relocatees and the influence to production and livelihood of relocatees. Operating Period of Project

During operating period of Shuangfeng urban flood control project, such works as embankments, sluices and pump stations will not pollute the environment, but make favorable effect to improve the current scattered sewage drainage along urban riverside, and the partial scattered sewage drainage outlet will be changed into concentrated drainage outlet. Meanwhile, the operation of sluices can drain the water pollutant in urban area to Ceshui River in time. Furthermore, Shuangfeng urban flood control project will greatly improve the flood control standard and the waterlogging harness standard in the seat of Shuangfeng County. It is proposed that the urban flood control standard will be improved from less than 1-in-ten-year occurrence to 1-in-20-year occurrence, and the waterlogging harness standard is that the 1-in-ten-year occurrence storm for 24 hours will be drained out in 24 hours during the gate close period. After completion of this project, the flood risk to Shuangfeng County will be greatly eased, and the property loss due to flood will be reduced, and consequently ensure a peaceful and content livelihood and career to the residents.

Hunan Hydro and Power Design Institute 17 Environmental Assessment Report Table of Shuangfeng County Urban Flood Control Project

Environmental Impact Analysis Environmental Impact Analysis during Construction Phase: i. Impact on Water Quality by Construction Wastewater Discharge The project construction wastewater mainly refers to that from sand and stone washing, that from concrete prefabrication and curing in the precast yard, and that from vehicle and mechanical equipment washing. The finished products from Xiangxiang could be purchased for required sand and stones of the project, wastewater containing oil produced in the sand and stone washing process would be treated by the sand and stone manufacturers, accordingly, water quality of river reach within the construction area will not be impacted by wastewater from sand and stone washing. The water quality of the river reach within the construction area will not be impacted by wastewater from sand and stone washing. Regarding the project, the concrete and reinforced concrete are 31100 m3, main pollutants produced from concrete mixing and curing process are suspended solids and alkalescent water, generally, SS concentration of wastewater is about 2000mg/L, and pH is 11~12. Calculate based on that 1m3 concrete curing will produce 1m3 wastewater, concrete wastewater of 1100 m3 will be produced during the construction period totally, about 50m3/s on average. After wastewater from concrete curing is discharged, SS concentration of local river reaches will rise and pH value will rise too, thus, contaminated zone alongshore near the sewage discharge mouth would be formed. The concrete curing wastewater is produced during the concrete curing process, with considerably scattered distribution. Restricted by wastewater production characteristics, the concentrated concrete wastewater treatment is difficult, thus, the project management shall be reinforced, try to reduce amount of wastewater from concrete curing. There are 60 fuel construction machines in the project totally, compared with similar projects, calculate based on that each kind of machinery will produce 0.8m3 of wastewater daily, then, machinery washing wastewater is 48.0m3 daily, and content of petroleum in the wastewater is about 40mg/L. After oil-containing wastewater flows into rivers, it will form a layer of oil film on the water surface, arrest re-oxygen process of water body, affect sense character of water body, or even damage aquatic lives, and impact water quality and aquatic lives reversely in a certain degree. Accordingly, the construction machinery shall be equipped with concentrated overhaul sites, carry out the oil-insulation treatment to oil-containing wastewater, and ensure that it is discharged after reaching standards. ii. Impact on Water Quality of Water Catchment of Shuangfeng County Waterworks The water catchment of Shuangfeng County Waterworks is situated at the upper reaches of Mishui River in the urban area of Shuangfeng County, near Hexi protection area stake number 3+800m of the project. The designed water catchment capacity of the waterworks is 40000t/d, and the water supply area is the urban area and adjacent villages and groups. The intake nozzle of the intake pump room is embedded in the river bottom, with a distance between the banks of about 50m. During construction process of the flood control embankment, embankment line stripping, earth material filling, concrete prefabrication, and other construction processes will produce loss of water and soil or discharge construction wastewater, with the main pollutants of mud and sand and suspended solids, and they will be discharged at the bank generally. Restricted by the construction characteristics, the feasibility to treat SS produced in the foundation stripping process is considerably small, while earth material filling, concrete prefabrication, and other processes could be mitigated by conservation of water and soil and wastewater harnessing measures. Accordingly, embankment line stripping is the main working procedure polluting water quality of water catchment of Shuangfeng County Waterworks. As the water catchment of Shuangfeng County Waterworks is situated at Mishui River, close to the end of Hexi flood control area basically, the length of river reach of the upper reaches which shall be built with flood control embankment is about 1km, while, as the

Hunan Hydro and Power Design Institute 18 Environmental Assessment Report Table of Shuangfeng County Urban Flood Control Project

embankment line stripping is conducted along river banks, it is distributed scatteredly, the intensity of pollutant source produced from the embankment line stripping is considerably small, and SS output is considerably small as well. Zhengjia dam is at 500m place at lower reaches of the water intake of Shuangfeng County Waterworks, with a height of about 3m. The obstructed river water would slow down flow velocity of water body, accordingly, the dam will impact the self purification capacity of water quality of riverway of Mishui River in a certain degree. Compared with natural rivers, after pollutants are discharged into Mishui River, the contaminated zone produced by it is considerably wide and short. Accordingly, water quality of water catchment of the Waterworks will be impacted probably. While, as the suspended solid removal is comparatively simple in tap water processing technique, the suspended solid concentration of effluent water could be effectively reduced by prolonging sedimentation time and adding flocculant. iii. Impact on Air Quality by Construction Impact of project construction on the environment are mainly produced in the following processes: exploitation of soil and stone material yard, production process of the construction camp, and conveyance of soil and stone, concrete aggregate, and concrete. i) Impact of soil and stone material yard exploitation on surrounding air quality Regarding the project, soil of 0.2883 million m3 and block stone of 0.1654 million m3 are required totally. The soil material yard is located in the County Gardening Yard in Chengxi, and the block stone yard is located in Shanjiajin at the place of 18km in the southwest part of the county. During construction of soil and stones, if the measures of conservation of water and soil can not keep up with it, and surface dust will be raised in dry and gale weather, and it will also largely impact air quality of the leeward area. The soil material yard and stone material yard of the project are all located in the suburb, few residents are distributed in the area around it, and it is also way from the material yard construction area, accordingly, the exploitation of soil and stone has considerably small impact on the residents around. ii) Impact of construction camp construction on surrounding air quality The construction camp is mainly responsible for concrete mixing, if sealing measures do not reach the designated aim during concrete mixing, partial particles will raising during cement adding process, thus, it will reversely impact the ambient air quality. As no residents are distributed in the area around the construction camp, construction will not bring adverse impact on air quality of residential areas around. iii) Impact of conveyance of soil and stone, concrete aggregate, and concrete on surrounding air quality The conveyance of soil and stone, concrete aggregate, and concrete shall pass the urban area, in normal conditions, they will be sealed and covered during the transportation, while, if sealing measures are not tight, partial materials will fall onto the ground during transportation, and dust will be raised once vehicles pass there. In addition, as trucks with high power are selected to convey materials required for the project, fuel motors will discharge a lot of tail gas, if overload happens during conveyance, the pollution due to tail gas will be more serious. Compared to construction situations of similar projects, dust pollution will diffuse along both sides of roads generally, when the distance between the subgrade and the ground is less than 3m, the max. dust appears at both sides of the road. With increased distance away from the roadside, the concentration will decrease gradually and tend towards the background value, in general conditions, the affected area is within 30m at both sides of the roadside. The main pollutants of tail gas from fuel of construction vehicles are NO2 and CO. The tail gas discharge belongs to line source and surface source one, the discharge capacity of its pollutants is comparatively low, the overall impact of tail gas discharge on the local air environment is considerably small. When conveyance vehicles pass partial road sections in the urban area, as there are numerous residential

Hunan Hydro and Power Design Institute 19 Environmental Assessment Report Table of Shuangfeng County Urban Flood Control Project

areas on both sides of roads of the urban area, the discharge of fuel tail gas will impact residents and units nearby in a certain degree. There are a lot of vehicles for transportation in the construction camp, dust arising from vehicle traveling and discharged fuel tail gas will impact the ambient environment in a certain degree. As the construction camp is selected in the suburb, construction camps on the left and right bank are far away from residential areas and sensitive spots. Accordingly, dust from the construction camp and vehicle tail gas will have considerably small impact on residential areas and sensitive spots, and establishment and removal of construction camp will also have a considerably small impact on air quality of residential areas and sensitive spots. The pollution of dust, tail gas, and local atmospheric environment will be largely impacted by the climate. Shuangfeng County belongs to the subtropical monsoon climate, the wind direction is of obvious seasonality. During summer and winter, the prevalent wind direction is north wind and northwest wind, and in spring and summer, it is the southeast wind. In the project area, changes of wind direction of small range obey the prevalent wind direction of the district. Based on the overall construction arrangement, the conveyance lines and flood control project construction sites are distributed along river banks of Ceshui River, and the main construction period is concentrated in autumn and winter. The main urban area of Shuangfeng County is located on the north bank of Ceshui River, namely, the upper drift, accordingly, the project construction has considerably small impact on Hexin protective area, and large impact on Hedong protective area. Shuangfeng No. 1 Middle School and Yongfeng Erwan Primary School are all located in the leeward direction, and the distance between these two schools and the construction embankment line is about 30m, and these two sensitive spots are all located in the side of the important communication lines currently. When vehicles to convey materials of the flood control project pass the sensitive spots, dust and tail gas arising from transportation will impact the air quality further. iv. Impact on Sound Environment by Construction Few residents are distributed near the soil and stone material yard and the construction camp of the project, accordingly, the impact of the project construction on the environment is comparatively small. When conveying construction materials of the project and constructing the flood control project, the above phenomena will be impacted in a certain degree owing to close to the residential areas and sensitive spots in the urban area. Noise produced by vehicle transportation belongs to the line source one, and noise from the machinery construction belongs to the point source. As the flood control project is conducted along Ceshui River and Mishui River, only construction of river reach near the sensitive spots will impact the sound environment sensitive spots. With completion of construction of the flood control project in the section, the impact on the sound environment will become zero. Accordingly, the impact period of noises is comparatively short. Based on the project scale and construction strength during the construction peak, the synthetical sound level of noise from the construction site is about 80dB (A) generally. Without regard to landform, barrier, plant sound absorption, and other additive attenuations, the impact of construction noises on sound environment of the residential area could be predicted by the distance decline mode of point sound source in the free sound field. Based on the site investigation, residential areas are concentrated near both banks of Ceshui River in the urban area of Shuangfeng County, with a distance between the construction site of 10~30m more or less, and bounding walls of sound environment sensitive spots, such as, Shuangfeng No.1 Middle School and Yongfeng Erwan Primary School are located at the bank of Ceshui River basically, and the distance between the classroom and the construction line is about 50m. The noise value is 64.4dB(A), 60.0dB(A), 54.0dB(A), 50.5dB(A), and 48.0dB(A) at the place of 30m, 50m, 100m, 150m, and 200m respectively. The normal monitoring data show that, the noise monitoring value of Shuangfeng No.1 Middle School and Yongfeng Erwan Primary School is 70.8dB(A) and 58.1dB(A) respectively, see table 6.1 for details of noise predication value of sensitive

The construction noise will impact acoustic environment of residential areas and units along Ceshui River in a certain degree, while the added value of noises is comparatively small, and main factors of overlimit predicted value of sensitive spots are that the noise background value of sensitive spots is considerably high, especially the noise background value of Shuangfeng No.1 Middle School reaches 70.8dB. v. Impact of Solid Waste on Environment The solid waste during the construction period mainly includes construction slag and domestic rubbishes, construction slag rises from temporary piling of excavated foundation earthworks, and main part of slag is mud and sand and stone. Regarding the project, the slag is 0.1653 million m3, and construction slag will occupy the land of 62000 m2 totally. If measures of conservation of water and soil are not powerful when throwing slag, serious loss of water and soil will occur. Therefore, spoil area must be protected. Try to combine engineering and plant measures to effectively control loss of water and soil of the spoil area, and prevent polluting the environment. Domestic rubbish for construction area is relatively fewer. Average construction workers in the period of construction per day are 360 persons or so. Calculating at 1.0kg of rubbish produced per capita, average produced rubbish is 360kg. If the domestic rubbishes are piled freely, not only scenery and air are affected, at some climate condition, but also the mosquitoes, flies and rats will reproduce much in quantity, accordingly, various infectious diseases will transmit among the construction personnel. In order to prevent environment being polluted by domestic rubbishes, domestic rubbishes shall be piled concentratedly, cleared and conveyed by special persons periodically. In addition, domestic rubbishes shall be embedded, and it is forbidden to throw rubbishes randomly, for it will pollute the environment. vi. Impact of Soil Erosion

Hunan Hydro and Power Design Institute 21 Environmental Assessment Report Table of Shuangfeng County Urban Flood Control Project

The main reasons of loss of water and soil of Shuangfeng County Urban Flood Control Project is excavation of main works foundation, land leveling of construction site, excavation of soil in the material yard, slag piling in the spoil area, and other construction activities. Generally, the loss of water and soil is comparatively serious at the beginning of construction, with progress of the project construction, implementation of slope protection, vegetation restoration, sodding afforestation measures, the loss of water and soil could be controlled and stabilized at a lower level. The area with loss of water and soil due to project construction includes: main works area, soil material yard, and temporary construction site, spoil area, etc. The area of newly-increase loss of water and soil is 45.03hm2, with a total amount of 36362t probably. vii. Impact of Land Acquisition and Demolition of the Project The land occupation of Shuangfeng County Urban Flood Control Project will impact Hetang Residential Committee of Yongfeng Town, Wenxin Residential Committee, Hongqi Village, Hengtang Village, Maoping Village, Litou Village, Jingwan Village, Yuanxiao Village, and Jingping Village. The cultivated land acquisition of the project will impact seven villages and groups, the cultivated land per capita is 0.72 mu, after project land acquisition, the cultivated land per capita is 0.63 mu, decreased by 0.09 mu per capita, and the land holding proportion is 11.9%. After project land acquisition, the cultivated land per capita of all affected villages and groups is above 0.5 mu, Yuanxiao Village and Hengtang Village occupy the most part, with a cultivated land per capita of 0.77 mu. Accordingly, the impact of land occupation of the project on cultivated land per capita is comparatively small. As the area of cultivated land per capita in the project land occupation area is considerably large, the cultivated land resources are abundant, during the economic rehabilitation, it is planned to carry out the resettlement of readjustment of cultivated land within the village, and 461 relocatees need resettlement. Accordingly, after resettlement, the production mode is the same as that before resettlement, and lives will not change largely, it is easily to carry out the production development. The resettlement in their existing village will be taken for relocatees, 461 relocatees need resettlement. After they are completely scattered, they will be resettled to the place over 50m from the embankment line, with convenient traffic, convenient power supply, and good water resources. In addition, they will build new houses with compensation funds, and lighting, ventilation, and environmental hygiene shall be taken into consideration. viii. Impact on Vegetation by Project Implementation The embankments and dams, counterpart projects, earth borrow yards, spoil areas, and other areas in Shuangfeng County Urban Flood Control Project will occupy some land. Based on the investigation data of current state of vegetation in the affected area, the top plant on the cultivated land in the project-affected area is the economic crop generally, and general group plant on the wasteland is celery wormwood, and shrubbery is the low firewood forest. No original vegetation in the project affected area, and no rare plants. As for the whole area, the impact of the project construction on the local vegetation is comparatively small. The forestry is temporarily occupied during the project construction period, as the project-affected area is featured by rich rainwater, suitable climate, and good soil quality, it is suitable for plant growth. After completion of the project, the vegetation on the temporary land occupation could be restored in a certain degree by manual vegetation covering measures. Compared with the similar hydraulic works, by means of manual vegetation measures, recovery of vegetation on temporarily occupied land normally takes three to five years. The original appearance of the forestry vegetation could be restored about 10 years. In addition, the implementation of the project could protect the urban ecological environment largely, prevent various vegetations in the protective area being attacked by flood, therefore, it will play an active role in restoration of the vegetation in the area.

ix. Impact on Human Health by Construction With mobilization of construction workers into the construction area, they will bring hidden troubles to the original living environment and human health. On the one hand, with mobilization of construction workers into the construction area, the population density and fluidness will increase, accordingly, the ratio of disease prevalence will increase too. On the other hand, as construction workers live in the temporary living quarters or residential area near the construction area, domestic services and facilities as well as hygiene and disease control measures of the construction area are hard to keep up with temporarily, in addition, due to large labor strength of construction workers, their immunity from disease will decline, if they do not pay attention to diet and living environment hygiene, infectious diseases will happen and prevail easily. Environmental Impact Analysis during Operation Phase i. Impact on Urban Water Quality The 20-year-occurrence standard is adopted for the flood control standards of Shuangfeng County Urban Flood Control Project. After the project is completed, ability of flood control and waterlogging drainage of Shuangfeng County will be reinforced so as to avoid inundated flood in the urban area resulting in destroyed urban environment and deteriorated water quality, therefore, it will do good to improvement of water quality in and out of the urban area. Regarding the internal river water body within the urban area, the implementation of waterlogging drainage project makes rainwater, sewage, and waterlogging in the urban area drained into Ceshui River by electric drainage stations and sluices of all drainage areas, reduces accumulated contamination in the water body of the internal river, as well as avoids polluted water body of the internal river due to obstructed discharge of contaminations. Therefore, the implementation of the flood control project will give positive effect to water quality of the water body in the urban area. ii. Impact on Social Economy After implementation of the flood control project, it could effectively resist flood attack to the city, avoid or largely mitigate large economic loss due to flood, and lighten the heavy economic burden arising from input of manpower, materials, and financial resources for flood control and disaster relief. Therefore, it will do good to sustainable development of urban economic construction, improve the investment environment, so as to create a superior condition for economic development of Shuangfeng County and a stable society. iii. Impact on Urban Construction After implementation of the flood control project, the urban flood control project will plan the rivershore embankments unifiedly, fully consider construction demand of the rivershore scenic belt. Together with forestry, grasses, and other scenic measures, the rivershore appearance will take on an entirely new look, and it will be propitious to urban development and construction. With the progress of the flood control project, traffic conditions and other infrastructures of the north part of the urban area shall keep up with it correspondingly, thus, it will accelerate development of the north part of the urban area. iv. Impact on Human Health by Project Implementation The inundant flood seriously pollutes the city, result in prevalent disease, as well as threaten person health of residents badly. After implementation of Shuangfeng County Urban Flood Control Project, the urban flood control capacity would be improved, it will also avoid or lighten pollution by flood disasters, as well as protect the ecological environment of the city and guarantee health of residents. Meanwhile, the establishment of the flood control project could eliminate the psychological burden of urban residents during the flood season, as well as create a peaceful and satisfactory production and living environment, which is beneficial to physical and mental health of residents.

Environmental Protection Measures I Water Environmental Protection Measure i. Design Standard The waste water produced by this project is mainly from construction sewage and temporary domestic wastewater. The main pollutant in construction sewage is SS, and that of the domestic wastewater is BOD5 and COD. The discharge thickness control index is as follows: i) Contruction sewage: In keep with the first level control standard prescribed by Comprehensive Effluent Standard for Sewage (GB 8978-1996), the discharge thickness of SS shall be controlled below 70mg/L, and that of petroleum-like products shall be below 5mg/L, but it is forbidden to discharge in the first level water source. ii) Domestic sewage: The main pollutants in the domestic sewage are BOD5 and COD, whose discharge thickness shall be controlled below 20mg/L and 100mg/L respectively and are forbidden in the first level water source in the protected zone in keeping with the Comprehensive Effluent Standard for Sewage (GB 8978-1996). ii. Disposal of Production Waste Water i) Wastewater sources and its components The production waste water is mainly from concrete mixing, concrete curing, and waste discharge with oil from machines since where there are no machine repairing plants and the waste can not be collectively disposed. The main pollutant caused by concrete mixing and concrete curing sewage is SS, whose thickness is approximately 2000mg/L. ii) Disposal technology and facilities arrangement During the construction period, this project will establish two construction sites where sewage from concrete mixing is produced. Concrete curing is relatively dispersedly laid along the dike lines. A. The two construction sites of this project are located near the urban area where there are drainage facilities that work well, therefore, the sewage from concrete mixing can be discharged into underground pipework after precipitation treatment and can not be directly drained into side water. The precipitation process shall be at least 2 hours and two rectangle-structured settling tanks shall be used for a daily sewage volume of about 100m3/d, 5×3×2m( length×width×height). The tanks shall be used alternatively. When one tank is full, use the other. After precipitation, the clean water on the top will be discharged into the pipework nearby, and the predicated sludge will be delivered by dredging pumps to sludge fields and cleaned by excavators if dried and delivered to the waste piles. B. Since the concrete curing places are dispersed and thus the waste water is difficult to dispose, management approaches shall be adopted, including controlling the water volume and curing times to reduce the water that flows outward to the minimum as required. iii. Disposal of Domestic Wastewater i) Wastewater sources and its components Domestic sewage produced in this project is mainly from daily washing and soil. Two living places are established for the project, and the people at construction peak that lives in the temporary residential places will reach 360, which will produce 43.2m3/d at most. The main pollutants are COD and BOD5. ii) Disposal technology and facilities arrangement

Hunan Hydro and Power Design Institute 24 Environmental Assessment Report Table of Shuangfeng County Urban Flood Control Project

The domestic sewage will be treated with septic tanks for a sewage ration of 120L/d, with a design population of 180 persons. The treatment process lasts 12hours, and the sludge will be excavated once every ninety days. The septic tanks shall be built with bricks for both waste water and soil, with earth covered at the tank top for the consideration of ground water. According to the parameters above, the selected volume of the standarded septic tanks is numbered 5, whose effective capacity is 12m3, and the type is 5-12A11 with a dimension of 6.81m×2.88m. The septic tanks are to be built near the temporary residential places, one in each construction site. The treated clean water on the top shall be drained to the underground pipes and the sludge on the bottom is to be manually excavated and delivered to the field as fertilizer. II Preventing and Controlling Measures for Air Pollution: i) Design Standard The air quality in the project area will adopt the Class II standards specified in Quality Standards for Environmental Atmosphere (GB3095-1996), and the exhaust air release will adopt the Class II standards specified in Comprehensive Effluent Standards for Atmospheric Pollutants (GB 16297-1996). ii) Prevention Measures According to the characteristics of the air pollution in Shuangfeng during the flood control project and the main air pollutants are dust, dirt and engine exhaust gas, the prevention approaches are made as the table below. Table 7-1 Atmospheric Environment Quality Protection Measures of Shuangfeng County Urban Flood Control Project Project Item Protection Measures Concrete mixing and Concrete shall be delivered with canning cementing truck and sent directly by delivery pumps to dust concrete mixers. prevention The constructed dike shall be immediately compacted and cured to prevent dust. When it is dry, Dike more water shall be used more frequently. The dike slope shall also be watered. Construction along banks The dike sections that are located at the densely populated area shall be fenced out with a supported fiber cloth to avoid pollution to the residents. Canning cementing trucks and exclusive cement deliver pumps shall be used in delivering the Concrete cement to concrete mixers, and more dust preventing measures shall be adopted. Watering mixing shall be adopted regularly. When it is dry, more water shall be used more frequently to protect station the works and other personnel from air pollution. The roads in the construction area shall be hardened and regularly cured, cleaned and watered to control the dust volume. One watering cart and four operators shall be arranged to water 4-6times every day at regular Road dust time, and more times when it is dry or in very high temperature and none if it rains. The road prevention sections to be watered are those paved with earth and rock, or delivery lines for construction materials and spoils. The water shall be pumped from the river in the construction area and sprinkled by 1.5L/m2 Trucks delivering cement, lime, rubbish and spoil shall be covered to avoid dusting. Domestic The temporary residential area and administrative area are laid near the road trunks of the fuels urban area, therefore canning liquefied gas or electrical appliances are preferable for air exhaust protection. control Management of constructing machines and vehicles shall be enhanced; clarifier shall be installed for large-sized machines and carrying vehicles and regularly checked and repaired to Other ensure the engine exhaust gas meets the environmental standards. Burning toxicants and substances that emits fetidity are forbidden

i) Waste Soil and Spoils Waste materials from construction (both temporary and permanent wastes included) shall be carried to spoil piles, and can not be piled along the construction line at will. Appropriate water and soil conservations measures shall be adopted accordingly. ii) Domestic Garbage Temporary garbage storage facilities shall be laid by the Contractor and the other units in operation. And one garbage station shall be constructed in the temporary residential area of the construction personnel, and regularly cleaned by persons in charge, 3-4 times a week, and the garbage shall be carried to and buried in the spoil piles and covered with earth to avoid flies. IV Prevention for Noise i) Design Standard The noise shall be controlled in keeping with Noise Limits in Construction Field (GB12523-90). ii) Prevention Measures a) Noise source control Noise source shall be well controlled in the construction area; machines shall be carefully checked before operation to reduce noise caused by abnormal operation. Strong noise sources such as aggregate screening and concrete mixing shall be laid away from the residential areas and temporary administrative area as far as possible. Advanced construction technology and low noise equipments and process shall be adopted, for instance, using polyurethane grindings for sand stone screening. Power-driven vehicles with low noise bugles shall be used and times of using bugles shall be reduced to the possible minimum. Those machines that cause very loud noise shall be used at some appropriate time, and night shifts shall be reduced as possible and installed with damping device. More repairing and curing shall be done for roads and machines to avoid potholes on roads. The carrying vehicles shall be controlled within relative speeds limits, and in the urban area especially in sensitive areas, the speed limit is 15m/h, and tooting is forbidden, since the impact of construction noise on the sound environment is significant. High noise mechanical construction is forbidden during the construction period from 10:00 p.m. to 6:00 a.m. Structural measures such as sound proof wall or economic compensation shall be adopted for areas seriously affected by noise so as to reduce or eliminate the impact. During the construction period, the equipments shall be regularly examined for reducing noise produced by equipments under normal operation. Properly arrange the time of using machines, reduce the construction at night and the transportation peak shall be arranged in the daytime. All the measures above can effectively reduce the intensity of sound sources. b) Noise spread path control The administrative and residential areas and construction sites shall be well laid, and the construction sites producing very loud noise shall be distributed far away from the residential area or blocked away. The fixed noise source that produce noises louder than 100dB shall adopt porosity sound absorption material to set up sound barriers to break the noise transmission route. Planting is also an effective way to reduce noise, thus more trees and grass shall be planted, which is also good for water and soil conservation. c) Protection of constructors and other noise receptors Labor protection shall be enhanced by improving working conditions and controlling the operating time in high noise environment within 6hours, and issuing protection appliances such as earplugs and noise-prevented helmets.

Environmental Management I Environmental Management Principle The main purpose of an environmental management plan ( EMP) on Shuangfeng County city flood management is to : Ensure the effective implementation of state and local environmental protection laws , regulations, standards and contract clauses during construction; Ensure that environmental protection measures, management plan and monitoring plan are implemented during the construction of Shuangfeng County subproject. required by Environmental Impact Assessment Report on Hunan Plain Area Urban Flood Control Project, II Environmental Management Scope

The scope of environmental management mainly refers to Shuangfeng County urban flood control project construction area, including dike alignment project, culvert gate project, soil disposal sites, and temporary life camp and resettlement etc. during construction. III Environmental Management Organization

Environmental management office of Shuangfeng County flood control project is responsible for managing this project environmental protection. Entrusted by environmental management office, environmental inspection engineers (EIEs) supervise environment when construction units exercise their building activity during construction period. IV Environmental Management Methods As regards to the important environmental problems existed in construction area or life camp, EIEs Environmental Inspection Engineers will issue The Notice about Environmental Problems through site inspection engineers, and require contractors to deal with problems within time limit. In accordance with the requirement of The Notice about Environmental Problems, The contractors must take any effective measures to solve problems on time and inform environmental engineer. For demanded Problems-solving in The Notice about Environmental Problems, the contractors cannot deal with them, or not tackle them after expiration. After consulting with environmental management office (EMO), EIEs will issue the notice about environmental action to contractors through construction inspection engineers. After 14 days of issuing the notice (after 7 days under special conditions), EMO or employed qualified persons can enter the site for handling environmental problems. Because of this, contractors need pay the increase of owners’ costs or loss. From next month, the loss will be deducted from contractors’ monthly payment. All written documents between EIEs and contractors must be officially signed and issued by construction inspection engineers. Every contractor and other units in operation ought to enhance environmental protection education to employees, increase consciousness for environmental protection, and abide by laws, legislations, standards, contract clauses and all requirements relating to environmental protection. For all actions against environmental protection laws, legislations, standards, contract clauses and this regulation, every contractor and other units in operation will be investigated accordingly. In accordance with specific condition of contract and current account, every contractor in construction area and large-sized units in operation must commission specialized environmental protection officials to establish environmental protection system and be totally responsible for environmental protection work of their own units (under EIEs’

Hunan Hydro and Power Design Institute 30 Environmental Assessment Report Table of Shuangfeng County Urban Flood Control Project

guidance). The specialized officials monitor periodically environmental items and parameters about environment (based on environmental monitoring plan or requirements of EIEs). They must submit a monthly newspaper about environment to EIEs every month, which reports this month’s work and monitoring conclusion. Shuangfeng flood management EMO Environmental Management Office can commission relative units or organizations to specifically inspect and monitor construction area and life camp periodically and aperiodically. Construction inspection engineers on site arrange monitoring work. The relative units or organization need notify contractors or other units in advance, and all units must coordinate with great efforts on the above-mentioned monitoring work. Every contractor and unit must ensure that measures of preventing pollution keep in step with the contracted items, or else, EIEs do the job by ways of written instruction of site construction inspection engineers.

Investigator： Time： III. Public Opinion i. Local Government ‘s Opinion The suggestions from Water Resources Bureau, Bureau of Finance, and City Governments are : The construction of this project is favorable for enhancing the capacity-controlling flood, accelerating economic development of Shuangfeng County. After completion of the project, the social, economic and environmental benefit will be great. The negative impacts on environment will be few. The affected scopes are limited to construction area, periphery partial areas. The affected period is mainly in construction phase. The project must be implemented as soon as possible. At present, the main environmental problem is that the dike construction makes more houses be demolished, so the compensation and resettlement must be coped. The main opinions of the local fisheries administration are: Because there are no natural fish eggs-laying ground, nursery ground and over wintering ground in Ceshui River of Shuangfeng County, and, no dredging channel and changing its course in flood control project, this project will have little effect on aquatic life in river stretch of water gage. The ideas from department of cultural relics are: In the scope of constructing flood control project in Shuangfeng County, there are no distributions of cultural relics and historical sites, so the cultural relics and historical sites will be affected. The Water Works considers: According to the manufacturing technique and disposal degree of water extracting and purifying, although suspended substances, sand have effects on water quality, the quality will be better after disposal. During construction process in flood control project, sanitary sewage drain cannot be established in protection areas for drinking water resource. And old sewage drain must be transformed and cannot be drained into the protection areas. ii. Public Opinion

The most attentions are : If paying for compensation on time and in full; If dealing with problem of employment; If advancing the standard of living. They also hope that this project can make them gain material interests, and make good use of ecological protection around construction areas. IV. Treatment of Public Opinion In the questionnaires, there is one copy, which disapproves this project. The reason is unwillingness of removal. The basic reason is: he doubts if resettlement fund can be on time and in full, 5 copies of questionnaire are ambiguous about this project. In the process of removal, it shall be in accordance with national regulations, resettlement funds must be on time and in full, so that the households will no have doubt. About ecological quality and environmental protection, the measures for preventing negative impacts must be put forward in EMP as far as possible. The comments and suggestions about construction quality, process must be told to project construction departments for reference through related channels. Project Office must inform the public of first-phase job, inviting and submitting a bid, the information of contractors and investment progress by ways of newspaper, TV and news briefing.
