Lingshui River, the 3rd grade branch of Xiangjiang River and the 1st frade branch of Ningyuan River, merges to Ningyuan River at Caojiatan in lower reaches of the county proper. It is 58.2km in total length and covers the river basin of 691.1 km2, including 552.9km2 or 79.9% of river basin in the county. The fall reaches 1125m, the gradient is 19.3‰, the average flow at estuary is16.8 m3/s, and the average runoff is 529.8 million m3. vi Current Status of Soil and Soil Erosion Ningyuan County is classified to be the low and medium hilly land terrain, with the limestone, sandstone and clay as the main forming-soil parent materials. The landform in the county is relatively flat, and the soil is fertile, with the red soil, paddy soil and yellow soil as the main. According to the Zoning for Water and Soil Conservancy in Hunan Province, the project area is rated as the medium loss area in rolling and mountainous region in south Hunan Province, with the soil erosion module of 2500~5000t/ km2.a. Due to the dense houses in old urban area in construction embankment section, and the gentle gradient of embankment section in development area that is vegetable land or barren, so the loss of water and soil is slight. The project will increase loss area of water and soil to be the 307.5 thousand m2 of ground disturbed by the project construction, so the increased loss of water and soil totals 510.5 thousand ton. vii Biological Resources Located at the evergreen broad-leaved forest region in the north of subtropics, Ningyuan County embraces 596 species in 87 families of arbors and shrubs. According to the species, 218 species are timbers, 96 species are economic trees (33 species are fruit trees), 152 species of protection forest, and 130 species of firewood forest. The dominant tree species include fir, masson pine and oil-tea tree. The lands permanently occupied by the project are located at both banks of Lingshui River, with the farmland, land for urban construction and riverbed beach as the main types and the field vegetation and urban green vegetation as the main vegetation. The temporarily occupied lands (borrow area, spoil site, construction access road, etc.) are mainly the dryland, garden plots and shrubs. The vegetation in economic rehabilitation area is shrub forest and scattered forest. The resettlement area is located in the urban area, so it has less impact on the vegetation. There are no rare protective wild plants and ancient trees in the project impact area. Due to human activities, there is less wild animal resource in urban area and temporary occupation area. The terrestrial animals include artificial breeding animals and wild animals, among which the livestock and poultry are the main artificial breeding animals, and the wild animals mainly live in the deep hillock with less human activities. The main terrestrial vertebrates include goat, wolf, masked civet and otter. The familiar birds and rodents are the main wild animals in the project area, and there is no rare protective wild animal in the project area. The main aquatic organisms in the natural water area are the fishes, with such cyprinid as grass fish, bighead, carp, chub and bream as the main species, in addition to such rare protective species as giant salamander and hilly turtles.

The infectious diseases ranking first five places are phthisis, hepatitis, dysentery, measles and typhoid in turn. iv Relics, Cultural and Recreational Sites Ningyuan County enjoys beautiful natural landscape, long history and many famous cultural relics. Jiuyi Mountain, the national forest park, is one of the six greatest landscape areas and the ten tourist areas in Hunan Province. Emperor Shun’s Temple on Jiuyi Mountain is reputed as the first mausoleum in China. Additionally, the urban areas embrace such historical and natural landscapes as Ningyuan Cultural Temple, Ningyuan Military Temple, General Liumeng’s Temple and Wugong (five-arch) Bridge. Among them, Ningyuan Cultural Temple was built in the Northern Song Dynasty, which is merely inferior to Confucian Temple in Qufu, Shandong Province, among the current cultural temples. With the stone carving as the essence of this temple, the pattern of “five dragons are playing with a ball” was carved on the red step in front of the hall, and 20 carved stones with various birds and beasts are standing around the platform and looking to three pairs of stone lions at Lingxing Door, Chongsheng Temple and red step respectively. Among the carved stones, 20 dragon and phoenix stone columns being 4.6~5m in height and 0.4~0.6m in diameter are the most delicate, which present grand majesty. This cultural temple is close to Chengbei Protection Circle 0+180m and about 50m far away from embankment line. As the second largest Confucian Temple throughout the country, this cultural temple was awarded as the national key cultural protective unit in 1997. v Urban Water Supply Facilities The urban water works of Ningyuan County is located at the upper reaches of Lingshui River in urban area, whose water intake is located at the place 1km of the upper reaches of Hongqi Dam and the catchment capacity reaches 20000t/m3. The water works can only serve 35 thousand residents and units in the urban area. The unreasonable layout of water supply network and the small diameter of tube greatly affect the water supply for old urban area, so it fails to supply water for new urban area currently, and the diffusive ratio of urban water supply is low. The government of Ningyuan County plans to expand the water works, and after expansion the water supply capacity is expected to be 60000t/d from 20000t/d currently. The water intake of Ningyuan County Water Works is situated in the project impact area, so the project construction will bring certain impact to it.

According to the estimate by Ningyuan County Environmental Protection Dept., the overall county has an industrial waste water discharge of 1.0054 million t/a including 504.54t/a SS, 1067.36t/a chemical oxygen demand, 3.9721t/a sulfide in addition to harmful substances of arsenic and Hg. The main pollution sources involve Lengjiang Paper Making Plant, Lengjiang Yarn-dyed Factory and a number of mine processing and smelting enterprises with the pollutants chroma of emitted waste water exceeding the standard specified by the state. The emission exits of industrial waste water are mainly distributed along the Lengshui River section in the county proper flood control circle and all pollutants in the county proper shall be drained into Ningyuan River through Lingshui River and then coverged into Xiaoshui, finally into Xiangjiang River. The emission of domestic sewage in Ningyuan County proper is about 0.876 million t/a, mostly directly drained into Lingshui River. The emission exits are distributed dispersedly along the two banks of the river in the urban area, and the domestic sewage mainly contains pollutants such as nitrogen, phosphorus nourishment substance and COD. ii Current Water Quality of River Sections In line with the Hunan Provincial Main Surface Water System Ambient Water Functional Zoning (Hunan Provincial local standard DB43-2004), the ambient water functional zoning of Lengshui River within the affected scope of Ningyuan County urban flood control project is as follows: the river section of 4.7km between Macaoping to Hongqi Dam is potable water source protective area and executes Class criteria of Surface Ambient Water Quality Standard; the river section of 7.5km between Hongqi Dam to the junction of Jiuyi River is agricultural water use protective area and executes Class criteria.

According to the statistical data from Ningyuan County Environmental Monitoring Dept., the water quality of Ningyuan County Waterworks Water Catchment is 100% up to the standard, and satisfies the Class criteria of Surface Ambient Water Quality Standard (GB3838-2002); the water quality of the urban area and the lower reaches river section is over the standard due to the impact by the domestic sewage emitted from the urban area. II Current Atmospheric Environmental Quality The ambient air pollution source in Ningyuan County Urban Area is mainly the domestic, industrial pollution source and tail gas emission by the vehicles. The pollutants impacting the ambient air quality in the urban area are mainly TSP and SO2, their pollution types are mainly soot pollutants caused by fuel coal and granule pollutants emitted by the industrial enterprises. According to the monitoring data on the environment of Ningyuan County, the content of SO2 and TSP in the urban area exceeds the Grade 2 national standard, for some places, for an instance, the peripheral area of County Cement Plant has quite poor air quality with 918.96t harmful substance content in waste gas (543.30t soot and 148t dust), 25.88mg/m3 air chroma, more than 85 times of the national standard. III Current Sound Environmental Quality The ambient sound quality of Ningyuan County proper is as usual, has little change in total compared with the last year and the average equivalent sound level is classified as the medium pollution. The main noise source affecting the ambient sound quality in the urban area is domestic noise, and the noise with the most strength is traffic noise source. With the adjustment of the industrial structure and layout as well as the strict management on

Hunan Hydro and Power Design Institute 10 Environmental Impact Report Table of Ningyuan County Urban Flood Control Project

construction noise, the scope affected by the industrial and construction noise sources is gradually decreased. However, the scope affected by the domestic noise keeps stably high, and the ambient sound in over 60% urban area suffers from the impact by the domestic noise source.

IV Main Environmental Problems Related to the Project: i The Overall Environment in the County Proper is Bad With the gradual increasing of population and fast development of economics (mainly the industry), the quality of ambient air in the urban area is becoming bad: one is the serious soot pollution incurred by the burning of the main energy, coal in the development of industrial enterprises; another is waste air and noise emitted by the increasing vehicles with the fast development of traffic automobile industry, which seriously affect the ambient air and sound quality with the noise exceeding the national standard. The fundamental facilities are not complete and the domestic garbage encircles the city seriously. The current drainage system in the city is in disorder and cannot satisfy the demands.

ii Low Wastewater Treatment Rate in the County proper The waste water and domestic sewage emitted from the industrial and mine enterprises without purification treatment can result in pollution on water quality after directly drained into water. For an instance, Ningyuan County has a number of mine resources, the industrial waste water and domestic sewage produced during the development and production process as well as the sulfide produced result in certain pollution on water. If the water consumption of residents at the two banks of Lingshui River is calculated in 150L/person per day, the waste water coefficient takes 80%, the annual discharge of domestic sewage is 1.314 million t, if the discharge of COD is calculated in 100g/person per day, the annual discharge of COD is 1314t. The industrial waste water and domestic sewage emitted by Lingjiang River Paper Mill and Yarn-dyed Plant as well as the chemical plant at river side not only affect the natural scenery but also do harm to the public health of residents at two banks. iii Air Pollution in the Urban Area Affected by the dust emission by the County Cement Factory, the dust in Ningyuan County urban area is over the standard, and in some places, the dust chroma in the air is seriously over the standard. iv Flood Disasters The urban flood control project construction in Ningyuan County has never been carried out, thus the flood and waterlogging disasters burst out frequently, when the incoming of flood season each year, water can overflow on streets, especially have boats sailing in the urban area. The shutdown or stop production incurred by floods exceeds 10 days every year, especially in 1973, exceeding 20 days, when the whole county was caught with rainstorm, resulting in several houndreds of houses collapsed and the direct economic losses mounting up to RMB 10 million yuan. The most serious in recent years was the flood occurred on July 7, 1994, which resulted in the direct economic loss mounting up to more than RMB 20 million yuan. According to the statistics, after our country was founded, 22 times flood and waterlogging disasters befall in the county proper within 14 years. It’s known form these that the occurrence of flood and waterlogging disasters is more and more frequent, and the losses incurred by floods are bigger and bigger, with the gradual expansion of the county proper scale and the fast development of the economics, the demand on resisting flood is becoming higher and higher, and more and more urgent.

v Blockage of River Course The increasing of population and the economic development of the overall county for many years result in over cultivation of Ningyuan River Water Basin, and promotion of riverbed year after year due to soil and water loss, where it is difficult to let boat sailing over it. In addition, the management on the river course is slacked, so that a lot of units

Hunan Hydro and Power Design Institute 11 Environmental Impact Report Table of Ningyuan County Urban Flood Control Project

and individuals occupy or even destroy the river course. Currently, the sewage emission, exploitation and construction without permission are quite serious, nearly 20 factories and mineries along the river emit over 11 million m3 waste water and 20000 m3 into the river each year, additionally, some units take liberty to occupy the river course for building of riverside structures, as result in reduction of flood passing capability of river course. Main environmental protection objectives (list name and protection level): i Environmental Protection Objectives Water environment: requiring the waters of various affected river sections to maintain their original environmental functions. Atmospheric environment: requiring that the atmospheric environment within the assessment scope is not polluted because of the project construction and that the air quality meets Grade 2 assessment criteria of Ambient Air Quality Standard (GB3095-96). Sound environment: The protection subjects are inhabitants and construction workers in the project affected area, requiring that the sound environmental quality meets Class 2 criteria of Ambient Noise Standard in Urban Areas (GB3096-93). Ecological environment: requiring to minimize the destruction on vegetation caused by immigration resettlement area, construction area, newly-built construction hauling road, borrow pits, and spoil pits, requiring to restore as soon as possible the destroyed vegetation and to adopt measures for compensating or mitigating the impact on aquatic ecological environment of reservoir area and dam during the project construction and operation phases, requiring to reduce as much as possible the destruction degree on ecological environment of the project area and peripheral areas caused by this engineering construction. Objectives of Social Environmental Protection: ensure the resettlement funds timely prepared and the domestic standard of the resettlers not worse than that before relocation. ii Main Sensitive Locations of Environmental Protection within the Scope of Assessment Table 3-4 Main Sensitive Locations of Environmental Protection for the Project

Project Analysis Construction Period of Project: I Construction Process The environmental impacts produced by Ningyuan County Urban Flood Control Project exist throughout the construction phase, during which the major impacts on environment caused by the project come from foundation excavation, vehicle transportation, land occupation of building, spoil disposal, and other engineering activities. Its construction technique process is as follows: A Flood prevention dike: earthworks excavation - -> earth material transportation - -> flood prevention dike filling - -> masonry grouted rubble revetment (slope protection)- -> sod revetment - -> concrete pavement or clay-bound macadam pavement. B Culvert gate and flood diversion channel works: foundation earthworks excavation ----→ cement soil filling—→ concrete casting —→ mortar rubble masonry→ earth backfilling→ installation of metal structures and electromechanical equipment. C Concrete works: Sand and gravel mining, flushing, and screening - -> concrete mixing - -> concrete transportation - -> concrete casting - -> artificial water spraying and curing. D Waste earth and spoil construction: unusable materials from foundation excavation and house demolition - -> vehicle transport - -> stockpile in spoil pits II Main Pollution Process The main pollution processes during the construction of Ningyuan urban flood control project is given below: (i) The foundation earth excavation for flood embankments, culvert gates, and flood diversion channels, 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) Such construction processes as the concrete precasting in sodding protection works for flood embankment, and the concrete placement and curing in culvert gate works 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 loss of water and soil. (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 406 persons in 65 households in 6 villages will be affected by Ningyuan Urban Flood Control Project, and 7150m2 houses shall be demolished. The demolition and economic rehabilitation will bring inconvenience to the relocatees and influence to the production and livelihood of relocatees. Operation Period of Project During operating period of Ningyuan Urban Flood Control Project, such works as embankments, culvert gates and flood diversion channels will not pollute the environment, but make favorable effect to improve the current scattered sewage drainage along urban

Hunan Hydro and Power Design Institute 15 Environmental Impact Report Table of Ningyuan County Urban Flood Control Project

riverside, and the partial scattered sewage drainage outlet will be changed into concentrated drainage outlet. Meanwhile, the operation of culvert gates can drain the water pollutant in urban area to Ningyuan River in time. Furthermore, Ningyuan Urban Flood Control Project will greatly improve the flood control standard and the waterlogging harnessing standard in the seat of Ningyuan County. It is proposed that the urban flood control standard will be improved to 1-in-20-year occurrence, the waterlogging harnessing standard to 1-in-ten-year occurrence, and the huge storm for 24 hours will be drained out in 24 hours. After completion of this project, the flood risk to Ningyuan 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.

Environmental Impact Analysis I Environmental impact analysis during construction phase: i Impact on Water Quality of Downstream River Section by Wastewater Discharge during Construction Phase The finished products in Daoxian County sand pit are purchased for sand and stone for the project, no wastewater produced by sand and stone washing will be drained in the construction area, and production wastewater which is drained in the construction area mainly includes concrete mixing and curing wastewater and vehicle and mechanical equipment washing wastewater. Generally, the SS concentration density of sand and stone washing wastewater is about 15000mg/l, and SS discharge concentration of wastewater produced from the concrete precast product curing is about 2000mg/L, and pH value is about 11~12. The total engineering quantities of concrete prefabrication and placing are 53840 m3, and the construction wastewater output is 600~800m3/d. The project area belongs to the river corrosive deposit relief, it is high in the east and low in the west, river runs off from east to the west, starts from the waterworks eastwards, and ends in Hongqi dam westwards. The topography is considerably flat, riverways are curving mostly, riverbed is narrow (river water erosion and man-made destroy), and the gradient ratio of the riverway is large (19.5‰). The flow of riverway in this river section is comparatively torrential, which will do good to diffusion and dilution of pollutants. If construction wastewater is drained into the lower reaches of the discharge mouth directly, it will affect its water quality, the river section with large pollution is situated within the place about 500m at the sewage drainage mouth, and concentration of suspended solid in the water body alongshore will increase largely. After wastewater from concrete curing is discharged, SS concentration of local river sections will rise and pH value will rise too, thus, contaminated zone alongshore near the sewage discharge mouth would be formed. The concrete mixing wastewater is produced by concrete mixing station in the construction camp, and it will be discharged concentratedly. 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 should be reinforced, try to reduce amount of wastewater from concrete curing. The project mechanical equipment includes excavator, loader, bulldozer, crane, and other vehicles, with an amount of about 80. Compared with similar projects, calculate wastewater from mechanical equipment washing by 0.8m3/piece.day, the daily discharge capacity of wastewater from mechanical equipment washing is about 64m3/d, and the oil pollution concentration of wastewater is about 40mg/L generally. 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 should 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. During project implementation, the domestic sewage is produced by construction workers mostly. The construction workers during the project construction peak is 850 persons/d, calculating water consumption of 150L/person.d (its wastewater coefficient is 80%), daily wastewater amount is 70t; its COD concentration will reach 300~400mg/L generally, thus, organic pollution will be produced. ii Impact on Water Quality of Water Intake of Ningyuan County Waterworks There is one waterworks under Ningyuan County Waterworks currently, its water intake is situated at the upper reaches of the urban area, within the construction area of the embankment line of protective circles of left bank and right bank of Lengshui River under Ningyuan County Urban Flood Control Project. While, the pollution during the construction

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

of the flood control embankment is mainly produced by loss of water and soil, embankment line stripping, and layout of gentle slope, its main pollutants are mud and suspended solid (SS). As the removal of SS in the water body is comparatively simple in the running water processing technique, the impact of suspended solid produced by construction on the water quality of the running water is considerably small. It is only required to extend sedimentation time for water intake during construction of river sections in the upper reaches, the water quality of water outlet could be restored to the original level. Regarding domestic sewage and oil sewage produced from construction, they should be discharged in the lower reaches of the water intake concentratedly, or, after corresponding environmental protection measures have been adopted to process it to reach the standards, it could e discharged, in order to reduce discharge capacity of pollutants, it is forbidden to discharge it in the protective area. (After it has been processed correspondingly, it could be drained into the urban networks), therefore, its impact on water quality of the water intake of the waterworks is comparatively small. iii Impact on Local 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 Besides the excavated materials of 0.1097 million m3 should be utilized, soil materials of 0.1725 million m3 and block stones of 72000 m3 are required for the project. The soil material yard is located in Lijiadong soil material yard at the southwest suburb of the urban area, and block stones come from Lianhuatang stone material yard near Lianhuatang Cement Plant at the east suburb of the urban area mostly. 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 basically, few residents are distributed in the area around it, 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 1# and 2# construction camps are located in the urban area, numerous persons are distributed around them, and the distance between construction camps and the residential area is about 30~50m; as 3# and 4# construction camps are located in the suburb, few persons are distributed around them. 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. Based on analysis on the crowd distribution around four construction camps, the impact of 1# and 2# construction camps on the air environment quality of residential areas is comparatively large, and impact of 3# and 4# construction camps on the air environment quality of residential areas is comparatively small. 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 should 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

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

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 and surface source one, the discharge capacity of its pollutants is comparatively low, and the 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 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. Affected by dust from vehicles on the conveyance roads and tail gas pollution, the air environment of sensitive spots in the urban area, such as, Wenmiao Temple, County No. 1 Middle School, County No. 3 Middle School, and County People’s Hospital, will be affected in a certain degree, while the distance is out of 30m, the impact could be mitigated. 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 distance between 1# and 2# construction camps and residential areas is 30~50m, and they are located out of the impact area basically. 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. As Ningyuan County belongs to the subtropical monsoon climate area, the wind direction owns obvious seasonal changes. The north and northwest wind is prevailing in autumn and winter, and southeast wind is prevailing in spring and summer. 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 Ningyuan River, and the main construction period is concentrated in autumn and winter. Therefore, the impact of the project construction on Chengnan area of Ningyuan County is comparatively big, while that on the residents in Chengbei area at the windward direction is comparatively small. iv Impact on Sound Environment in Construction Area and Peripheral Areas Regarding environment around the soil and earth material yard and construction camp, the area near 1# and 2# construction camps belongs to the urban area, dense residential areas are distributed in there; the sound environment sensitive spots which are distributed along the embankment line of the flood control project include: Wenmiao Temple, County People’s Hospital, County No. 1 Middle School, County No. 2 Middle School, and County No. 3 Middle School. During conveyance of materials required for the project and construction of the flood control project, as residential areas in the urban area and the sensitive spots are nearby, the above mentions places will be impacted a certain extent. Noises from vehicle conveyance belong to the line source, and noises from machinery construction belong to the point source. 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. Based on the site investigation, there are dense residential areas and units near the project construction area. The distance between residential areas, units, and schools and the construction site varies from 30~200m. Thereinto:

As Wenmiao Temple, County No. 1 Middle School, and County People’s Hospital are close to the embankment line, about 20-60m, noises produced by the embankment project construction all exceed Class-II Standard stipulated in Urban Regional Noise Standards (GB3096-93), it will bring adverse impact to its normal entertainment and amusement, learning, treatment and recreation of patients. Therefore, corresponding measures to manage and control noises should be taken, as the noise from construction in night exceeds the standard badly, the construction in the afternoon and night should be

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

controlled strictly, and it is forbidden to operate the equipment with loud noise.

As the distance between County People’s Hospital, County No. 2 Middle School, and County No. 3 Middle School, and several sensitive sites and the embankment line are about 100m, which are further relatively, while, the construction noise exceeds the standards still, therefore, the noises from construction of the embankment line will impact these sensitive sites still, and it is required to reinforce management and controlling during the construction process. In addition, the construction noise will largely impact construction workers, accordingly, the construction unit should try to allocate construction machinery feasibly, and adopt corresponding measures for sound insulation and absorption, so as to protect construction workers. v Impact of Solid Waste on Environment The solid waste of the construction period mainly includes construction slag and domestic rubbishes from the temporary living quarters. The construction slag mainly comes from temporary pile of the excavated earthworks of foundations, with the main parts of clay and sand and stone. One spoil area is planned in the project, with a total slag amount of 0.2324 million m3 and with a land occupation area of 2.9hm2. During construction, if construction slag is piled randomly, it will produce comparatively serious loss of water and soil, therefore, prevention measures should be taken for the spoil area. By means of engineering and plant measures, the loss of water and soil of the spoil area could be controlled effectively, in addition, environment pollution could be prevented. Domestic rubbish for construction area is relatively fewer. Average construction workers in the period of construction per day are 850 persons or so. Calculating at 0.8kg of rubbish produced per capita, average produced rubbish is 680kg daily. 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 should be piled concentratedly, cleared and conveyed by special persons periodically. In addition, domestic rubbishes should be embedded, and it is forbidden to throw rubbishes randomly, for it will pollute the environment. vi Impact of Soil Erosion The main reasons of loss of water and soil 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, and the area of loss of water and soil is mainly concentrated in the local construction area. 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, and other water and soil conservation measures, the loss of water and soil could be controlled and stabilized at a lower level. The area of loss of water and soil due to the project construction mainly includes exposed earth surface due to topsoil excavation of main works and earth borrowing yard, land occupation of temporary facilities in the temporary construction site, slag pile in the spoil area, and new exposed earth surface and side slope after completion of the main works of the flood control embankment, and its newly-increased area of loss of water and soil is 0.3075 million m2 probably. The newly-increased loss of water and soil of the project mainly includes that from earth surface excavation, land occupation of temporary facilities, construction waste soil and slag, and new exposed earth surface of main works. Calculating according to the construction period of three years, the newly-increased loss of water and soil of Ningyuan County Urban Flood Control Project is about 0.5105 million t, of which, without any

Hunan Hydro and Power Design Institute 20 Environmental Impact Report Table of Ningyuan County Urban Flood Control Project

preventive measures, the loss produced by slag is 0.4729 million t, and loss of water and soil from temporary topsoil pile during exploitation of the soil material yard is 37600 t. vii Impact of Land Acquisition and Demolition of the Project Ningyuan County Urban Flood Control Project will impact 6 villages of Chengguan Town, 406 persons of 65 households should be relocated, houses of 7150m2 should be demolished, thereinto, brick-concrete, 4800 m2, brick-wood, 1500 m2, sundry house, 850 m2; bounding wall, 715 m2, sunning ground, 780m2, 6 wells, 11 scattered fruit trees; temporary land occupation of 216mu, of which, cultivated land, 125 mu, pond, 0.90 mu, wasteland, 25 mu, and rural housing plot, 4.6 mu. Accordingly, from the overall analysis, the impact of project land occupation on local land utilization and reduced cultivated land per capita is not big. Based on the demolition and land occupation resettlement plan of the project, after economic rehabilitation of residents, their environment will not change, and their living habits and production conditions are kept same as before. In addition, as few persons need economic rehabilitation and they are close to the urban area, it is easy to carry out economic rehabilitation and development. Through the resettlement of shed vegetables and reasonable development of the secondary and tertiary industry and other measures, as well as supported by production and development funds and various preferential policies, the production and living conditions of residents will be higher than the original level. viii Impact on Vegetation by the Project Implementation The embankment line arrangement, counterpart projects, earth borrow yards, spoil areas, and other areas in Ningyuan 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, and main varieties of chopped vegetations due to woodland acquisition are manual economic forest, shrubbery, and weeds. As the percentage of coverage of local forestry vegetation is comparatively large, the woodland resources are rich, compared to the area of project affected area with woodland, the impact of reduce woodland and chopped forests due to project land acquisition on the regional 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 personal 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.

x Impact on Cultural Relics and Landscape Wenmiao Temple is located at the north side of Chengwenmiao Road of Ningyuan County, with a distance about 50m between the embankment line, and main activities of the project, which impact it, are vehicle transportation and embankment construction near river sections. Dust from construction, tail gas from vehicles transportation, and construction noises will impact ambient environment of Wenmiao Temple adversely. Therefore, corresponding measures (such as, establishing barriers, watering, utilizing plants, etc.) should be taken to mitigate or eliminate its impact. II Environmental Impact Analysis during Operation Phase i Impact on Urban Water Quality Regarding Ningyuan County Urban Flood Control Project, the flood control standard could be improved to 20-year-occurrence, and the waterlogging harnessing standard could be improved to 10-year-occurrence. The ability of flood control and waterlogging drainage 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 Ningyuan River by electric drainage stations and culvert gates 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. In addition, if waterlogging in the embankment as one supplies of groundwater is drained into the external river immediately, it will obviously reduce water level of local groundwater, therefore, it will reduce waterlogging in the urban area to penetrate and pollute water quality of groundwater in the superficial layer, accordingly, its positive impact is obvious. ii Impact on Social Economy The construction of Ningyuan County Urban Flood Control Project could guarantee security of lives and properties of the people, and create a peaceful environment for normal production and livelihood of urban residents and all sectors. Try to avoid direct economic loss by flood disasters, in addition, the implementation of the project could avoid various potential or indirect economic losses by production halt due to inundated flood, emergency service, or disaster relief, as well as 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, accordingly, it is significant to stable economy and sustainable development of Ningyuan County. iii Impact on Urban Construction The road-embankment combination principles are adopted for embankment in the flood control project, concrete is paved on the crest pavement, and prolongation, straightening, and connection of partial embankment sections will improve urban traffic. With the implementation of the flood control project, the buildings against rules along the riverway are cleared, and old and broken houses in low-lying section are rebuilt. In addition, enlarge the embankment with grass and engineering measures, and form a rivershore scenic belt, therefore, the urban landscape will be improved largely. In the project, the culvert gate and flood diversion channel will be newly built or rebuilt, and it will improve the existing waterlogging drainage capacity of Ningyuan County, therefore, discharge problems of sewage, rainwater, and wastewater in the urban area could be solved basically. In a word, integration of the flood control and waterlogging drainage project and municipal

Hunan Hydro and Power Design Institute 22 Environmental Impact Report Table of Ningyuan County Urban Flood Control Project

construction will beautify appearance of a city and environment of both banks along the river. iv Impact on Ecological Environment The favorable impact of the flood control project on the ecological environment mainly reflects in that it reduces ratios of flood and waterlogging during the flood seasons as well as it well protect the ecological environment of the prevention area. It is because of that once flood and waterlogging happens, urban houses, suburb farmland, water areas, trees, and grassplots will be inundated, ecological environment of the protective area will be destroyed seriously; moreover, flood contains a lot of noxious substances generally, it will bring potential adverse impact to fauna and flora after its disappearance. v Impact on Human Health by the Project Implementation With flood and waterlogging disasters, various germinas will breed and diffuse, living environment of residents will be destroyed, and it will cause prevalence of various diseases easily. Secondly, frequent flood and waterlogging disasters will bring adverse impact to psychology of the people, once in the flood season, the urban residents who are threatened by flood will become high-strung, and with high incidence of a disease, in addition, flood and waterlogging disasters will make the city power cut, break off the communication and information, cause an intense supply of materials, and disturb normal living orderliness of the people. Accordingly, these will induce worrying feeling of the people, and do harm to their health. After implementation of the 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.

Hunan Hydro and Power Design Institute 23 Environmental Impact Report Table of Ningyuan County Urban Flood Control Project

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) Construction 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 Wastewater i) Wastewater sources and its components The production waste water are mainly from concrete mixing, concrete curing, and waste discharge with oil from machines since where there is no machine repairing plants and the waste can not be collectively disposed. The main pollutants caused by concrete mixing and concrete curing sewage are SS, whose thickness is approximately 2000mg/L., Ph value is generally from 11 to 12 and the petroleum content of the machine sewage discharged at construction intervals is about 40mg/L. ii) Disposal technology and facilities arrangement During the construction period, this project will establish four construction sites where sewage from concrete mixing is produced. Concrete curing is relatively dispersedly laid along the dike lines. A The four 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 pipelines 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 pipelines 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. C The waste water containing petroleum will be treated at the machine repairing field. Collecting channels and separation tanks will be constructed to collect and treat the oily wastewater, and the separated oil on the top will be recycled and the clear water will be released. iii Disposal of Domestic Wastewater

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

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 850, which will produce 102m3/d at most. The main pollutants are COD and BOD5. ii) Disposal technology and facilities arrangement The domestic sewage will be treated with septic tanks for a sewage ration of 120L/d, with a design population of 200 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 standard septic tanks is numbered 5, whose effective capacity is 12m3, and the type is 5-12A11 with an outline dimension of 6.81m×2.88m. The septic tanks are to be built near the temporary residential places, and four tanks will be constructed. 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 Ningyuan 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. Table7-1 Protection Measures for Atmospheric Environmental Quality of Ningyuan County Urban Flood Control Project

Environmental Management I Environmental Management Principle The main purpose of an environmental management plan ( EMP) on Ningyuan County city flood control 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 Ningyuan County subproject. required by Environmental Impact Assessment Report on Hunan Plain Area City Flood Control Project, II Environmental Management Scope

The area of environmental management is Ningyuan County flood control project area, including dike alignment project, culvert gate project，waste soil disposal sites, the borrow pit areas and temporary life camp etc. during construction. III Environmental Management Organization

Environmental management office of Ningyuan 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

About the important environmental problems existed in construction area or life camp, EIEsEnvironmental Inspection Engineerswill 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 inspection 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 31 Environmental Impact Report Table of Ningyuan 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. Ningyuan flood control EMOEnvironmental Management Officecan 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 construction inspection engineers on site.

Relevant opinions and suggestions

1. To answer these questions, please mark “√”. 2. All questions can be answered with multi-choices. Remarks 3. For opinions and suggestions not addressed by these questions, please fill in the column “Other opinions and suggestions”. Investigator: Time: The main opinions of the local fisheries administration department are: Because there are not natural fish eggs-laying ground, nursery ground and over wintering ground in Lingshui River in Ningyuan County, this project will have little effect on aquatic organism in river stretch of water gage. But foundation stripping in flood control project will influence on aquatic organism, changing partly the place for survival, inhabitance and foraging, and bringing some negative effects on grown-up and distribution of aquatic organism. The ideas from department of cultural relics are:: Ningyuan is an old city, with long history. During building dike distribution areas and construction sites, there hiding some cultural relics and historical sites under the earth, it must enhance protection and management work, guarding against destroying cultural relics, during construction. During construction, Wen Temple must be protected. 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) Mass Opinions Through public consultation, the public know about the feature, positive and negative effects of flood control project. Most of them are of opinions that this project will be social project, and hope that it will be started at an early time, in order to reduce hidden trouble from flood. At the same time, they are also aware that this project will have some negative effects on natural, social and ecological environment, especially the large-scale housing removal. The most attentions are: If carrying on resettlement appropriately, and increasing living standard after resettlement; They also hope that this project can make them gain material interests, and consider ecological protection and establish the scenic view around construction areas.

Hunan Hydro and Power Design Institute 35 Environmental Impact Report Table of Ningyuan County Urban Flood Control Project

In the questionnaires, there is 1 copy which disapproves this project; 2 copies of questionnaire are ambiguous about this project. The main reasons of these 3 copies disapproving the project: during project investment and choice of contractors, the secretive process will result in corruption, which will waste government investment, and bring about damage of project safety, flood control safety. The loss of materials and property will be great. The resettlers are not sure if compensation fee can be given on time and will be equivalent to their loss, and worry about the lowering of living standard.
