Before 1970s, the river was crystal clear to the bottom with numerous fishes, is the breeding base in Zoushi Town. But with the development of the town, large amount of the production and domestic wastewater and sewage have been discharged into the river. Nowadays, the river has become a river of wastewater and sewage, seriously influences people’s life quality and the ecological environment of the town. Meanwhile, Changsha Environmental Protection Vocational College 4 Hunan ECOP for the Riverway Harnessing Works with the acceleration of urban construction, the water surface in the urban area is constantly reduced. The river is 4.8km long in the urban development planning area and 3km long in the urban area in Zoushi Town. This project plans to clean the section of Zouxi River that is 3km long from east to west along the street. After on-site investigation, the riverway in the urban area is 3km long, with mid-low stream about 40m wide and upstream about 30m wide. The upstream boundary of the riverway for treatment is about 200m to the entrance of Zouxi River to Yuan River, and there is no water intake in Zouxi. Therefore, there are no residential water intakes and drinking water reserves in 1000m on the upstream and 2000m on the downstream of the riverway for treatment. Enterprises in the upstream of Zouxi River are mainly Zoushi Oil Factory, Changde Friction Material Factory, State Grain Storage etc. the main pollution sources are sewage produced by residential living around the upstream, a few amount of industrial wastewater and other domestic garbage and sewage. The main reason for the sediments in the inner Zouxi River is the insufficient management. There were no garbage disposal area, and garbage in urban area was poured into the inner river. The urban sewer constructions were not supporting, and the domestic wastewater was discharged into the inner river. The domestic garbage was randomly discarded into the inner river, caused sediments and serious pollution of the inner river. The silt piles for above 1m, main components including domestic garbage, some constriction wastes, rots of river grasses and other sewage. In the compiling process, this Environmental Codes of Practice, the Project Organizations in Zoushi Town have entrusted Changsha Environmental Protection Vocational College Analysis and Testing Center to inspect the bottom sediment in the riverway. The place for sampling was on the downstream of the riverway for transformation, and totally seven indexes have been inspected including pH; Pb; Cd; Hg; As; Cu and Zn. The analysis was Changsha Environmental Protection Vocational College 5 Hunan ECOP for the Riverway Harnessing Works conducted according to the analysis method regulated in the Environmental Quality Standard for Soil GB15618-1995 . According to the inspection results of bed mud in the riverway provided by Changsha Environmental Protection Vocational College, the pH value of silt in this riverway is 5.7, so it belongs to acid soil (<6.5); and the content of pH, Cd, Hg, As, Cu and Zn in the riverway can meet the standard requirements of acid soil specified by the Control Standards for Pollutants of Agricultural Sludge（GB4284-84）, see Table 1-1 for detailed inspection results. Table1-1 Bed Mud Monitoring Results (Unit: mg/kg) Monitoring pH Pb Cd Hg As Cu Zn Items Monitoring Value 5.7 111 0.29 0.17 5.69 77 133 When Standard acid soil Value ( 6.5) 300 5 5 75 250 500 According to properties of the silt, this project plans to treat the silts with the method of covering with earth and greening after drying. And details are shown in the “Environmental Codes of Practice for the Construction Stock Yard�. 1.4.2 Construction Scheme In the Zouxi River harnessing works, the river reach with a length of 3000m will be renovated. The construction content includes the riverway desilting, sewage clearing, establishment of the retaining wall, revetment and banquette on both sides of the riverway, laying of sewage intercepting pipe with a length of 6000m on both sides of the riverway and afforestation with an area of 18000m2. While the available culvert pipes beneath the road which crosses the river will not be renovated. 1.4.3 Engineering Materials The sandstones, steels, woods and other building materials used in the project construction can be purchased from the nearby markets. Changsha Environmental Protection Vocational College 6 Hunan ECOP for the Riverway Harnessing Works Some of the earth used in the project is construction excavated earth, and the insufficient part is excavated from Gaowan Earth-excavated Yard which is the public Earth-excavated Yard located in Zouxi Town, 5.5km to the construction site. The project will not set new Earth-excavated Yard. The stones needed in the building of protective slopes are supplied by existing stone yards in Qinglong Village, Zoushi Town. The project will not set new stone yard, the sandy gravels are outsourced and transported by river. The concretes needed are commodity concretes purchased from Changde Julong Building Materials Co., Ltd., about 2km to the construction site. And no new concrete mixing plants will be set on the construction site. 1.4.4 Construction Machinery The main construction machineries include excavators, bulldozers, vibrating rollers, trucks (including damp trucks), mortar mixer etc. 1.4.5 Project Construction 1.4.5.1 Demolition of Dangerous Buildings Zouxi River harnessing works involve the demolition of a few dangerous buildings, including 1~3 storey(s) brick-concrete buildings and other auxiliary structures such as the terrace with an total demolition area of 3630.94m2. The demolition of dangerous buildings will generate dust, construction waste slag and noise, of which: the wet method operation can be adopted to effectively reduce the dust; proper arrangement of the construction time can effectively alleviate the impact of the noise on residents’ living; and the construction waste slag can be recycled by choosing proper area; if it’s difficult to operate, the waste slag can be transported to the designated slag yard for disposal. And the requirements on selection of the waste slag yard are shown in Table 4-3. 1.4.5.2 Riverway Desilting and Sewage Disposal The riverbed of Zouxi River is relatively narrow and the current flow is extremely small, thus the method of drying dredging is suitable. Numerous machineries can be equipped in the dry desilting to enlarge the operation Changsha Environmental Protection Vocational College 7 Hunan ECOP for the Riverway Harnessing Works simultaneously and shorten the operation period. The disposal construction is visual and clear, occupies less lands and silts produced in the desilting have low water contents. Conduct the construction diversion through cofferdam method, set the construction cofferdam at the center of the riverway and divide the riverway into two sides, one side for construction and the other side for diversion of original riverway. After the construction diversion, dispose the garbage on the construction surface firstly, dry the garbage for several days after disposal to reduce the operation with water, and then conduct the mechanical excavation. Adopt sacked earth for the cofferdam structures, use earth excavated in the construction as possible. The riverway desilting and sewage disposal shall be conducted in dry seasons, and whole-line dredging shall be conducted on the riverway due to the whole-line construction. When having the construction conditions, dispose sewages on the upper layer of side slope on riverway steps according to riverway prototype to facilitate the operation of construction machineries and safety in construction under on low riverway layer, and then use backdiggers to excavate earth and silt. Since the riverway is in the urban area of Zoushi Town, there are no conditions for temporary waste silt yard and garbage station set along the line, therefore the disposed garbage shall be timely disposed by the Environmental Department of the Town. No temporary storage yard will be set, disposed silt shall not be piled on the sides, but transported to regulated waste silt yard directly by closed tankers. 1.4.5.3 Filling of Retaining Walls and Building of Protective Slopes Construction of retaining walls and protective slopes shall be conducted with the cofferdams of desilting equipments after the desilting. The clay materials for the filling of retaining walls are transported by trucks from the earth- excavating yard to the filling operation surface, and are discharged. The manual labors coordinates with the bulldozers to level materials, then Changsha Environmental Protection Vocational College 8 Hunan ECOP for the Riverway Harnessing Works compact them with rollers, conduct the building of protective slopes after the completion of retaining walls. 1.4.5.4 Sewage Intercepting Pipe Works The sewage intercepting pipes are paved along the riverway. The earth construction is synchronically conducted with the riverway disposal construction, and there is no independent excavation. Discharge the pipe, fix the pipe, and connect the joint, conduct closed water test, quality inspection and acceptance after treatment on riverway basement. 1.4.5.5 Passage Hardening and Greening The riverway section after treatment is 24m wide, among which, the water surface is 15m wide and 4m deep. 1m wide greening belts and 3m wide concrete pavements will be set on two sides. The construction will be conducted after the silt displacement, sewage displacement, building of protective slopes with rocks and embedment of sewage intercepting pipe. The pavements, greening earth construction and the filling of retaining walls are constructed synchronically. Only vegetations are planted and concrete roads are paved in this stage. 1.4.6 Construction Organization The riverway harnessing, sewage intercepting pipe construction on the horizontal and vertical construction areas in the treatment project are basically arranged independently, therefore they can be conducted in parallel to short the construction time. The project is located in the urban area of Zoushi Town with convenient transportation. There is highway connecting the project area and the waste silt yard, and it is generally no need to construct temporary construction roads.

ECOP for the Management of the Construction Site and Equipments Management of the Construction Site 5.1 Management of the Construction Site Construction sites mainly include the main works construction area, construction production areas and construction access road. 5.1.1 Main Works Construction Area 5.1.1.1 Analysis on pollution sources of the main works construction area Construction of main works mainly include the demolition of dangerous buildings, riverway desilting, sewage clearing, retaining wall filling, rip-rap slope protection and intercepting sewer works as well as passage hardening and afforestation, of which, the intercepting sewer is laid along the river-way, the earth-rock works ad river-way desilting are carried out synchronously but not excavated separately. The environmental impacts and river-way dredging and desilting works will be analyzed together. (1) Demolition of dangerous buildings Zouxi River harnessing works involve the demolition of a few dangerous buildings and the demolition process will generate dust, construction waste slag and noise. (2) Riverway desilting and sewage disposal Conduct the construction diversion through cofferdam method. After the construction diversion, dispose the garbage on the construction surface firstly, then conduct the mechanical excavation. The disposed garbage shall be timely disposed by the Environmental Department of the Town, no temporary storage yard will be set, disposed silt shall not be piled on the sides, but transported to regulated Waste silt yard directly by closed tankers. The main environmental influencing factors in the construction process are mainly reflected in the following aspects: The disturbance at the river bottom in the cofferdam construction process will make the suspended matters such as sand, silts and others in some water Changsha Environmental Protection Vocational College 34 Hunan ECOP for the Riverway Harnessing Works bodies increase, at the same time, cause impact on the living environment of aquatic life. Construction machinery and reduced oil in the machinery repair process will cause oil pollution to the water body. The excavation of silt in the riverway desilting project will diffuse odor. A large amount of garbage, silt and other solid wastes will be disposed in the riverway desilting project. The operation of construction equipments will give off intense noises, and some equipments might produce vibration. The riverbed and bare earth surface caused by excavation of earth will cause relatively intense water erosion in short time. (3) Filling of retaining walls, building of protective slopes and sewage intercepting pipe construction Construction of retaining walls and protective slopes shall be conducted with the cofferdams of desilting equipments after the desilting. The clay materials for the filling of retaining walls are transported by trucks from the earth- excavating yard to the filling operation surface, and are discharged. The manual labors coordinates with the bulldozers to level materials, then compact them with rollers, conduct the building of protective slopes after the completion of retaining walls. The main environmental influencing factors in the construction process are mainly reflected in the following aspects: The blocking, waterproof or other temporary constructions are not conducted on time, causing dust pollution. The earth construction destroys vegetations along the line, and causes bare earth surface, thus makes partial ecological structures in areas along the line changed accelerates the water erosion. Improper protection on vehicles for earth transportation will cause dust pollution. The operation of construction equipments will give off intense noises, and some equipments might produce vibration. Changsha Environmental Protection Vocational College 35 Hunan ECOP for the Riverway Harnessing Works (4) Roads hardening and greening The pavements, greening earth construction and the filling of retaining walls are constructed synchronically. Only vegetations are planted and concrete roads are paved in this stage. Among them, the concretes are purchased commodity concretes and not mixed on the site. Therefore, the main environmental influencing factors in the construction process are the noise and vibration produced by operation of construction mechanical equipments. 5.1.1.2 Pollution control measures of the main works construction area (1) Demolition of dangerous buildings Wet method operation can be adopted to reduce dust. Proper arrangement of the construction time can effectively mitigate the impact of noise on residents’ living.

ECOP of the Construction Stock Yard Materials such as sandstone, steels and wood for project construction use can be bought from the surrounding market. Soil needed in the project is partially from excavation. The insufficient part is taken from Gaowan borrow pit, where is located in Zoushi and belongs to public borrow pit. No new borrow pit is built. The load distance of Gaowan borrow pit is 5.5km. Building rocks needed in the rock protective slope are provided by the rock stock yard of Qingshi Village, Zoushi Town. No new rock yard is built. Sand pebbles are outsourced and adopt river transportation. Concrete required should be commercial concrete and purchased from Changde Julong Building Materials Co., Ltd. The haul distance is about 2km, so the concrete mixing plant will not be set on the construction site. Therefore, the construction stock yards needed by the project are mainly waste slag yard and waste silt yard. 7.1 Waste Slag Yard 7.1.1 Analysis on Environmental Impact Factors of the Waste Slag Yard The riverway harnessing works construction process may produce certain quantity of construction waste slag, mainly including the excavated spoil, waste road building materials, and waste stones and silt due to site clearing. Following environmental impacts may be brought about if they are improperly disposed. (1) The ground surface exposure of the waste slag yard will bring about serious dust pollution if proper measures are not taken. (2) If retaining works or temporary water proof works for the waste slag yard are not well done, soil erosion will happen. (3) The destruction of the ground vegetation will bring negative impacts to the ecological environment. Changsha Environmental Protection Vocational College 48 Hunan ECOP for the Riverway Harnessing Works (4) Ground vegetation destruction and ground surface exposure due to earthwork excavation will bring negative impacts to the local landscape. 7.1.2 Environmental Impact Control of the Waste slag yard To avoid negative environmental impact caused by the setting of the waste slag yard, the environmental codes of practice puts forward the following environmental protection measures: (1) General requirements: Select the site in strict accordance with the requirements of “Part 4 ECOP on the Preparation Stage of the Construction Site� and transact relevant formalities. If abandoned earthwork is produced, firstly consider recycling it on the original site or other construction sites, or reusing it for the borrow pit vegetation recovery. Avoid setting the spoil pit separately, which can eliminate the impact of the borrow pit on environment fundamentally. If it cannot be recycled, firstly investigate if there is designated local building muck disposal site; if any, transact the muck clearing formalities and transport it to the designated disposal site as specified. (2) Dust control measures: The waste slag yard should be compacted layer by layer, effectively suppressing the dust. Sprinkle water and suppress dust, reducing the dust pollution caused by surface exposure. (3) Soil erosion measures: Take corresponding water and soil conservation measures in accordance with the requirements in “Part 9 Soil Erosion Control� to prevent soil erosion. (4) Ecological impact control: Before the construction of the waste slag yard is commenced, the topsoil shall be excavated for land reclamation. The topsoil should be piled on a relatively flat area within the construction site, and blocked by building up a Changsha Environmental Protection Vocational College 49 Hunan ECOP for the Riverway Harnessing Works temporary block with bagged soil. Meanwhile, set temporary drainage ditches and sand sedimentation measures around it and cover it with dust screen.

Carry out vegetation recovery in accordance with the requirements in “Part 11 Ecological Restoration� after the soil borrowing. (5) Landscape impact control: Take corresponding environmental protection measures in accordance with the requirements in “Part 16 Landscape Impact Control�. 7.2 Waste silt yard 7.2.1 Analysis on Environmental Impact Factors of the Waste Silt Yard A great number of silts might be excavated in construction process of the riverway harnessing works, according to the inspection results of bed mud in the riverway provided by Changsha Environmental Protection Vocational College Analysis and Testing Center, the pH value of silt in this riverway is 5.7, so it belongs to acid soil (<6.5); and the contents of pH; Cd; Hg; As; Cu and Zn in the riverway can meet the standard requirements of acid soil specified by the Control Standards for Pollutant of Agricultural Sludge (GB4284- 84). In the riverway harnessing project, after silts are transported by closed tanker to the Waste silt yard, silts should be treated with method of covering with earth and greening after drying. Therefore, it has great significant to do the environmental protection work of the Waste silt yard. The natural drying refers to transport the silt with closed tankers directly to the waste silt yard, and the water in the silt will be drained out through evaporation and automatic flow. After analysis, the impacts caused by drying of silt and setting of the waste silt yard are mainly reflected in the following aspects: (1) The organic contents of silt in riverbed are relatively high and under anerobic condition for long time. If exposed, odorous gases diffuse. Changsha Environmental Protection Vocational College 50 Hunan ECOP for the Riverway Harnessing Works (2) The water content of the silt is relatively high, and wastewater will be drained during the piling process. (3) The rain wash will caused erosion of silt, causing secondary pollution. (4) The covering earth is not restored timely after embedment of silt, causing dust pollution. (5) The damage of vegetation on earth surface will caused adverse impact on the ecological environment. (6) Insufficient temporary blocking or waterproof construction will cause water erosion. (7) The damage on vegetation on earth surface and bare earth surface caused by land occupation of the waste silt yard will cause adverse impact on some landscape areas. 7.2.2 Environmental Impact Control of the Waste silt yard To avoid the adverse impacts caused by the treatment of silt and setting of the waste silt yard, the following environmental protection measures are proposed in this Environmental Codes of Practice: (1) General requirements: Select the site in strict accordance with the requirements of “Part 4 ECOP on the Preparation Stage of the Construction Site� and transact relevant formalities. (2) Fetor control measures Take protective measures for the construction personnel, for example wearing protective respirator and masks etc. Spray deodorants during in construction process to reduce defusing of dust and fetor gases. (3) Waste water control measures Set several barriers in the waste silt yard, prolong the residence time of the remained water of the waste silt yard in the piling sites, increase tail water drainage flows and intensify the natural sedimentation effects. Set a sedimentation basin at the discharge outlet of the waste silt yard Changsha Environmental Protection Vocational College 51 Hunan ECOP for the Riverway Harnessing Works to conduct medical sedimentation and reduce the pollutant content of the remained water in the piling site, then drain the wasted water. (3) Silt erosion prevention and control measures: Build cofferdams around the waste silt yard, do basement treatment of the waste silt yard well, adopt natural clay to prevent seepage and set the drainage channels. (5) Dust pollution prevention and control measures: Compact timely to effectively control dust generation. Sprinkle water and suppress dust to reduce the dust pollution caused by ground surface exposure. (6) Soil erosion control: Take corresponding soil erosion control measures in accordance with the requirements in “Part 9 Soil erosion Control� to prevent soil erosion. (7) Ecological impact control: Before the construction of the waste silt yard is commenced, the topsoil shall be excavated for lad reclamation. The topsoil should be piled on a relatively flat area within the construction site, and blocked by building up a temporary block with bagged soil. Meanwhile, set temporary drainage ditches and sand sedimentation measures around it and cover it with dust screen. It can be used for the ecological recovery of the campsite after the construction has been completed. Carry out vegetation recovery in accordance with the requirements in “Part 11 Ecological Restoration� after the silt has been desiccated. (8) Landscape Impact Control Take corresponding environmental protection measures in accordance with the requirements in “Part 16 Landscape Impact Control� after the project completion. Changsha Environmental Protection Vocational College 52 Hunan ECOP for the Riverway Harnessing Works 8. Environmental Quality Management 8.1 Water Environment Quality Management The impact of riverway harnessing on the water body along the line mainly includes: the impact of riverway desilting on the surface water quality, and impact on water environment by the domestic wastewater of the construction campsite, oil stains dripped and leaked by the construction machinery and stacking of construction materials and earthwork. To mitigate the impact of the riverway harnessing on water environment, the environmental codes of practice mainly adopts the following environmental protection measures, detailed in Table 8-1.

Changsha Environmental Protection Vocational College 60 Hunan ECOP for the Riverway Harnessing Works 9. Soil Erosion Control 9.1 Causes of Soil erosion Causes of soil erosion mainly include: (1) Heavy and concentrated rainfall is an external force for soil erosion of the project area. (2) The filled sub-grade is piled and cushioned by sand soil and stone material, and formed by compaction in layers. Though the internal structure is tight, the surface structure of the side slope is still loose, and such forms of soil erosion as sheet erosion and shallow gully erosion are easily to happen. (3) Damaged side slopes (such as new domes and side slopes caused by sub-grade excavation) are steep, or even up-right. The side slopes are made of soil, stone or mixture of soil and stone. As the side slope gradient is large, violent water erosion is easily to happen in case of rainstorm. Meanwhile, rainfall may bring about small-scale collapse and landslide easily, resulting in serious soil erosion. Therefore, the erosion intensity is extremely strong. (4) The dome structure of the topsoil stacking area is loose, with poor stability and weak erosion resistance. The erosion is in forms of sheet erosion and rill erosion, etc; the erosion intensity is strong or violent. (5) The construction of most construction access roads adopts the half- excavated and half-filled method, which reduced the soil consolidation capacity and increased the land exposure area. The clearing, compacting, burying and damage of the vegetation along the line reduced the soil and water conservation function of the original landform. (6) The site leveling, clearing or excavating process of the construction production and living area resulted in large-area exposure of ground surface, damage of vegetation and loss of the soil and water conservation function. However, the laying of buildings will include the aggregate washing, concrete mixing and construction equipment cleaning, and all these processes will Changsha Environmental Protection Vocational College 61 Hunan ECOP for the Riverway Harnessing Works produce construction waste water, which may bring about new soil erosion. In addition, after the construction has been completed, dismantling of temporary structures, and site leveling and loosing will also produce violent soil erosion. (7) Stripping the topsoil vegetation to form the borrow pit or borrow dome may disturb the stability of the original land and form large-area exposure surface, all of which may bring severe soil erosion. (8) The waste slag yard is generally made of stone or mixture, and is stacked in the form of dome or filling the concave. And the top surface is usually flat or has certain slope. The soil erosion forms include sheet erosion and rill erosion, and the erosion intensity is moderate or strong. The stability of the naturally formed loose side slope is poor, the gradient is steep, usually , 30° 40° and erosion resistance is extremely poor. The soil erosion form is surface erosion or gulley erosion, and the erosion intensity is violent. The waste slag is an important soil erosion area in road construction. 9.2 Soil Erosion Prevention and Control Schemes Soil erosion mainly takes place in such areas as the main works construction area, construction production area, construction access road area, construction campsite, borrow pit and waste slag yard. The soil erosion is mainly caused by the damage of the ground vegetation and exposure of ground surface. To mitigate the soil erosion brought by construction, the environmental codes of practice puts forward the following soil erosion control measures. 9.2.1 Construction Area of the Main Works The topsoil shall not be piled at the surface runoff collecting area and in the areas affecting construction or with smooth traffic as well. Instead, it shall be temporarily piled within the land acquisition area on both sides of the sub- grade. To avoid the collapse of the earthwork, temporary weaved soil bag block shall be set around the topsoil. And the temporarily piled topsoil will be used as the covering soil of greening later. Changsha Environmental Protection Vocational College 62 Hunan ECOP for the Riverway Harnessing Works The disposed silts shall be cleaned and removed timely. Set blocks for temporarily packed earthwork for preventing rain wash. Timely carry out the side slope protection of the retaining wall. 9.2.2 Construction Production Prevention and Control Area Construction production area mainly includes lime soil mixing station and stacking yard of construction materials. Control focus is soil erosion. Harden the cement on the site due to frequent traffic and the needs of piling materials. Set temporary retaining ditches beyond low-lying project area in case rain washing. Conduct dust prevention cover to topsoil and piled materials, prevent rain washing and polluting surrounding environment. Arrange construction period properly, shorten temporary land occupation time, recover vegetation or conduct reclamation upon construction completion. 9.2.3 Prevention and Control Area of the Construction Access Road Protection and drainage works shall be done well for the newly-built construction access roads. Arrange construction period properly, shorten temporary land occupation time, and recover vegetation or carry out reclamation upon construction completion. 9.2.4 Prevention and Control Area of the Construction Campsite Carry out temporary greening by planting grass and shrubbery for the work shed and part outside the hardening area so as to beautify the campsite environment. Build the brick-up drainage ditch so as to eliminate the site water log quickly. In the late period of the project, dismantle the work shed and remove the hardening area, and carry out land remediation and vegetation recovery. Changsha Environmental Protection Vocational College 63 Hunan ECOP for the Riverway Harnessing Works 9.2.5 Prevention and Control Area of the Waste Slag Yard If it is difficult to implement the earthwork balance, it’s required to set the waste slag yard; and the lap and low-lying areas should be selected as the waste slag yard. The slag retaining wall shall be set at the underside of the waste slag yard before discarding slag according to the topographic features, and the building of the slag retaining wall shall be set according to the stacking position and topographic features of waste slag, which shall be economical, safe and reasonable. Water intercepting ditches shall be built on the waste slag yard for blocking the sheet flow, and sedimentation basins shall be built up on both ends. When the gradient ratio of the intercepting ditch is large, energy dissipation facilities shall be set. The waste slag shall be rolled timely and drainage ditch shall be set after the waste slag has been rolled level. Ecological restoration of the waste slag yard shall be carried out after the project has been completed. 9.2.6 Prevention and Control Area of the Waste Silt Yard Select col or low-lying land as the waste slag yard, and the site selection shall meet the requirements listed in Table 4-2. Build cofferdams around the waste silt yard, do basement treatment of the waste silt yard well, adopt natural clay to prevent seepage and set the drainage channels. Water intercepting ditches shall be built on the waste silt yard for blocking the sheet flow, and sedimentation basins shall be built up on both ends. When the gradient ratio of the intercepting ditch is large, energy dissipation facilities shall be set. The silt shall be rolled timely after desiccation and drainage ditch shall be set after the waste slag has been rolled level. Ecological restoration of the waste silt yard shall be carried out after the Changsha Environmental Protection Vocational College 64 Hunan ECOP for the Riverway Harnessing Works project has been completed. Changsha Environmental Protection Vocational College 65 Hunan ECOP for the Riverway Harnessing Works 10. Storage of Chemicals and Risk Prevention 10.1 Overview The storage facilities for chemicals shall be located in the construction production area, and the site selection shall strictly conform to regulations in “Table 4-1 Requirements on Site Selection of the Production Construction Area�. There are various chemicals, among which many explosive, toxic and irritant chemicals are harmful to environment and human bodies, therefore it is significant to standardize the storage of chemicals and formulate the risk prevention plan. See Table 10-1 for the danger marks of common chemicals. Figure 10-1 Danger Marks of Common Chemicals Changsha Environmental Protection Vocational College 66 Hunan ECOP for the Riverway Harnessing Works Chemicals usually used in the road construction process are mainly diesel oil, engine oil, coating and others. If leakage happens, they will pollute the soil and water bodies on ground surface, and may cause fire and other accidents. Therefore, the Environmental Codes of Practice put forward the management requirements from such 2 aspects as the storage of chemicals and risk emergency plan. The chemicals shown in Table 6-1 (if any) shall be managed according to requirements of the Code. 10.2 Requirements on storage of chemicals When coating, gasoline and diesel oil are delivered into the construction sites, the acceptance personnel shall carefully check whether the packages are in good condition and oil leakage exists. If oil leakage happens, the coating, gasoline or diesel oil shall be refused and sent back. Special warehouses shall be set for oil and chemical solvents and other items stored in the construction production areas and warning signs shall also be set. The leakage resistance treatment shall be carried out on the ground and emergency accident-handling materials such as absorption packages/sand/sawdust shall be prepared. Formulate the accident emergency plan and provide training to the workers before they enter the construction sites. 10.3 Requirements on Risk Prevention The construction unit shall formulate the accident emergency plan in advance, arrange corresponding responsible persons who shall timely handle the accident and notify it to the environmental supervision unit and town project organization agency once an accident happens. The risk and accident emergency plan shall include the following contents: (1) Fire disaster prevention management measures Carefully implement relevant laws, regulations and clauses on fire safety management issued by the state and government, and conform to the Changsha Environmental Protection Vocational College 67 Hunan ECOP for the Riverway Harnessing Works operation standards made by the enterprises.
