1. DESCRIPTION OF THE SHIEMEN SUBPROJECT

1.1. Subproject Overview

Flood protection will be provided by constructing dikes, gated drainage culverts, drainage channels, pumping stations, and through river course dredging and rehabilitation.

The Subproject will establish protection zones according to the Overall Layout of Shimen Urban Development and in combination with the distribution of water system and natural terrace: Dikes for the East City Protection Zone (Chengdong) starts in the west from the harbor of Shimen Management Harbor Management in Yanjia Dam, by Tujiahe, Shejiaxi to the City Oil Plant, 6.55km long in all; dikes for the Baofeng District Protection zone start in the west from Xinjiekou, by Shizinao, Majiahe, Daxing to Qinglong, 13.25km long in all.

Flood control scope: This subproject establishes two protection zones namely Dongcheng Area and Baofeng Area. After alternatives compared, it is decided to remove interdikes and upgrade the existing section between Shenjiaxi to Yishi to expand the protection zone from Yangjia Dam by Yonggu, Shenjiaxi to Wuliping and Yishi, from 5.6km

2to 6.4km

2 in area, while Baofeng District

Protection Zone will be expanded by removing interdikes and upgrading the existing dikes between Majiahe and Qilong, from Xinjiekou by Majiahe to Qinglong, and thus the acreage increases from 17.7km

2 to 21.6km

2, and consequently the total protection area of the two

protection zones will reach 28.0km2.

Overall layout of waterlogging control: Considering the existing drainage system, and the flood and terrace characteristics of the mountainous area, the waterlogging relief area will be controlled by sections, adopting high drainage for high lands and low drainage for low lands, integrating flood relieving and gravity drainage, gravity drainage and pumping station, and structural measures and non-structural measures to attain effective drainage according to different situations.

The main works are: I) flood control works i) Construction of 7.63km new earth dikes, including 1.9.km in the Dongcheng Protection

Zone and 5.73 in the Baofeng Protection Zone; ii) Upgrading dikes, 9.41km, including 7.8km earth dikes and 1.61km flood wall. iii) Construction of revetment for dikes 14.8km and riprapping 0.4km. iv) Construction of 9 new culvert gates; II) Waterlogging relieving i) Construction of one new pumping station with 3 pumps (555kw) ii) Construction of one new flood diversion channel, 3.97km long; iii) Rehabilitation of two drainage channels, 3.77km in all.

1.2. Location

Shimen County is situated in the northwest of Hunan Province, at the border of Hunan Province and Hubei Province, bordered by Li County, Linli to the east, Cili and Taoyuan to the south, Sangzhi and Hefeng to the west and Wufeng and Songzi to the north. It is between 110°29 to 111°33 longitude east and 29°16 to 30°08 latitude north, with a total area of 3973km

2, 12.1%of

which is farmland. The proper city is located on the upper reach of the Lishui River, which divides the county into two parts, one in the south and the other in the north. The north city area includes the old urban area and east city area, and the southern part is called Baofeng District. Both parts belong to Lishui I grade alluvial terrace.

The overall Subproject Study Area (SSA) is defined as the flood protection zone, which has an area of approximately 5.2 km

2. For the purposes of this environmental evaluation the Subproject

Environmental Impact Area (SEIA) is defined as including:

- a zone approximately 100 m wide measured from the average perpendicular trend of both bank of the Lishui River, commencing 200 meters upstream of the start of dike construction and ending 200 meter downstream of terminus of dike construction;

- a zone approximately 100 m wide measured from the average perpendicular trend of the route for the flood diversion channel;

- a zone approximately 100 m wide measured from the average perpendicular trend of the drainage pipe.

The above zones will encompass the direct impact zones from most of the Subproject activities, including the creation or upgrading of dikes, the construction of the flood diversion works, and the construction of drainage and pumping works. In addition, according to the requirements of

Page 10: Initial Environmental Examination - adb.org · PDF fileInitial Environmental Examination June 2007

HUNAN FLOOD MANAGEMENT PROJECT

SHIMEN COUNTY INITIAL ENVIRONMENTAL EXAMINATION (IEE)

JUNE 2007 PAGE 2

National Environmental Impact Assessment Technical Guidelines, the SIEE is also defined as including:

- the area within a 100 m radius of the edge of the borrow pits;

- the area within a 100 m radius of the edge of the sites for spoil disposal; and

- the areas within a 100 m radius of the edge of the sites where displaced persons will be resettled.

1.3. Detailed Description

1.3.1. Dikes

The Shimen County has no existing dikes along both sides of Lishui except 5.49km in the old urban area on the north bank, and 1.163km in the Baofeng District. The existing dike between Sanjiangkou to Xinjiekou on the north bank will not been taken into consideration for distance comparasion to both banks since the south bank is a mountain slope. The banks from Xinjiekou to Shizinao is 4820m long, and the width of the existing watercourse is between 294m to 630m, which will be balanced by 500m; the banks from Shizinao to Shenjiaxi is 5000m, and the existing watercourse is between 450m to 800m in width, which will be balanced by 500m.

Type of dikes: New earth dikes are more suitable economically in the Dongcheng Area and Baofeng Area since not many house appropriations are involved. The existing dikes in the old urban area will be upgraded and reinforced by constructing earth and rock dikes with 1 meter height wave wall. In these two areas dikes lower than the standard are all earth embankments, 9.14km, which will be upgraded by earth dikes, and the section from Pile No. D0+000 to D1+610 in the Dongcheng Area will adopt wave walls.

Dike crest elevation: The dike crest elevation will be ascertained by design water level in keeping with the Design Sepecifications for Dike Works (50286-98). See Table 1-2 for dike crest elevations.

1.3.6. Borrow Pits and Spoil Piles

Block stone borrow pits: Block stones will be used mainly in grouted stone bottom and flood wall and Xinguanzhen block stone quarry will be the main provider. The block stones in this quarry are dolomites and limestone with sound rigidity and high quality, and will be delivered by 8t dump cars with an average delivery distance of 5 to 18km.

Sandstone borrow pit: The Lishui section in the project area has an abundant reservers of sandstone, and there are three sandstone borrow pits at Zhongdu, Chengjiahe and Shenjiaxi, who provides mainly quartz sandstone, sandstone and silty sandstone of high quality with relatively sound roundness, low mud content and abundant reserves. The average delivery distance is between 2km to 8km with convenient communication.

Earth borrow pit: The low hill land near the south railway station in the Baofeng Area and Hanyang earth pit in the Dongcheng Protection Area are selected to be earth borrow pits because of short delivery distance and convenience in exploiting;

Spoil piles: The overall volume of spoils of this project is 392,800m3. Based on the principle that

the corrie and bottom land shall be utilized as much as possible and small number of residents live around, three spoil piles will be established, one on the left bank and two on the right bank covering 12.09hm

2. DESCRIPTION OF THE ENVIRONMENT

2.1. PHYSICAL RESOURCES

2.1.1. TOPOGRAPHY

Hunan Province is enclosed by mountains and hills to the east, south and west, and drains northwards to the Yangtze River. Mountains and hills occupy approximately 75% of the province, and the remaining low lying area (Dongting Lakes) is part of the Yangtze River floodplain. The majority of Hunan Province is formed by the mountainous natural catchments of the four major tributary rivers which flow into the Yangtze River. The center and northern parts of the province are generally low, forming a U-shaped basin with Dongting Lake at its center. Shimen County is located at the northwest of Hunan Province and the border of Hunan and Hubei. Shimen County borders Li County and Linli on its east; Cili and Taoyuan on its south, Sangzhi and Hefeng on its west; and Wufeng and Songzi on its north. Located between E110°29’— E111°33’ and N29°16’—N30°08’, the area Shimen County totaled 3973km

2, and the

area of cultivated land accounts for 12.1 percent of total area. Shimen County seat is located at the middle and low reaches of Lishui River, whose protective area amount to 28.5 km

2, and with

the total population of 0.1316 million. Lishui River passes through Shimen County seat from west to north, which divides the county seat into south and north urban areas. The urban areas on north bank include old urban area and east urban area, while the south bank is Baofeng area with both banks on the alluvial terrace I. The Baofeng area is flat, while the urban areas on north bank (east and old urban areas) are fluctuant.

2.1.2. GEOLOGY AND SEISMOLOGY

Located at the northwest edge of Dongtinghu Basin, Shimen County witnesses the Lishui River passing through urban area and forming an alluvial plain. Hills and low mountains are erecting at both sides of valley, forming an obvious landscape of stepped landforms. Located at the left (north) bank of Lishui River, Baiyun Mountain is sinuous and connected with the northern mountainous area in Shimen County. Located at the right (south) bank, Shijiufeng Mountain extends from west to east like a belt, and the mountain range is meandering and fluctuant. The altitude reaches 300~400m with the difference of 200~300m. The front edge of low mountain is hills, which alternates with valley and is 150~100m in altitude and over 50m in altitude difference. The stratum in urban area of Shimen County includes Jialingjiang Group of Triassic (T2j), Cretaceous (K), Quaternary, and manual earth filling (from old to new). According to the China Zoning Map of Seismic Intensity with the scale of 1: 4,000,000 issued by state earthquake bureau, the basic seismic intensity of this district is rated at Grade VI.

2.1.3. CLIMATE

Located in the subtropical monsoon climate region, Shimen County enjoys a moderate climate, four distinctive seasons, sufficient precipitation, great humidity, much sunlight, and short frost period. According to the statistics of 1960~1995 observation data of Shimen County weather station, the climate characteristics of this district are shown in the Table 2-1.

2.1.4. SURFACE WATER

2.1.4.1. HYDROLOGY AND FLOODING

Located at the lower reaches of Lishui River, Shimen County controls catchment area of 15113km

2. Two large-scale hydraulic works of Jiangya and Yutan at the upper reaches in Shimen,

together with Zaoshi Reservoir under construction, have the effect on the flood and runoff at this section.

Shimen Hydrologic Station (originally Sanjiangkou Hydrologic Station) was built in the urban area of Shimen County along the basin of Lishui River in Feb. 1950, and removed to Yueliangyan reach on Jan. 1, 1951 with the catchment area of 15053km

2. On Jan. 1, 1980, it was relocated in

Chengguan Town of Shimen County, and renamed as Shimen Hydrologic Station with the catchment area of 15113km

2.

According to the observation data of Shimen Hydrologic Station, the flood frequently occurs at the river basin of Lishui River, and the flood with the flux at peak over 12000m

3/s amounted to

one in three years on average. Sometimes, there were several times in one year. For example, five floods occurred in 1980. The large flood at the basin of Lishui River generally happens between the last ten-day of June and the first ten-day of August. The historical floods and those with the actual flux at the peak surpassing 14000m

3/s checked by Shimen Station all

occurred in such period. The ebb and flow of flood endured 2 ~ 4 days, most with single flood peak, few with complex peaks. The historical maximum flux at flood peak in Shimen Station is observed to be 19900m

3/s (July 23, 1998), and the maximum flux in 72 hours amounts to 3.33

billion m3.

According to the analysis on observation data of each control station along Lishui River, the following three representative combinations will create the flood in Shimen County: the centers of storms in August 1980 and June 1991 were located at the upper reaches of Loushui River and Xieshui River respectively, which were the main source; the centers of storms in June 1954 and July 1998 were situated at the middle and upper reaches of trunk stream, which resulted in the flood in Shimen County; and in July 1964, there was widespread rain in the river basin, and the complex flood with the main peak in Shimen followed was formed due to equal water from trunk stream and branches.

2.1.4.2. WATER QUALITY

The water intake of Yanglinggang Water Works is set up at 500m of lower reaches of Sanjiangkou Hydropower Plant, which is supplied to the most residents in urban area as the domestic and industrial water. The river reach (stake No.: old urban area 1+000 to 2+010) is evaluated as the Class I protection zone for water source, whose water quality shall comply with

VEGETATION The soil vegetation in Shimen County belongs to Huazhong vegetation zone system, and the vegetation zone is classified as subtropical typical evergreen broad-leaved forest region, and vegetation zone at mountainous plain, hilly land and valley basin at northwest Hunan Province (evergreen chinquapin forest, Liangyeshuiqinggang forest, masson pine forest, cypress forest, and tung tree forest). The vegetation can be classified into 5 types, namely coniferous forest, broad-leaved forest, deciduous broad-leaved forest, shrub and artificial vegetation. Coniferous forest: With masson pine and fir forest as the main; Broad-leaved Forest: With many tree breeds and in a status of complex existence in multi-layer Deciduous broad-leaved forest: With sawtooth oak, hornbeam, grandifoliate poplar and linden as the main; Shrub and brushwood: With Indian azalea, cogongrass, Xunzi, China-cane and herbage of the grass family; Artificial vegetation: With such timbers as fir, masson pine and common sassafras, in addition to such economic forest as tung tree, tea-oil tree and as the main. The development trend of forest vegetation in the county: the vegetation is developing to the simple and unstable phytocoenosis, and with the obvious trend of inverted development, the virgin shady vegetation (evergreen chinquapin, Nanmu wood, chestnut, etc.) are gradually replaced with masculine vegetation (masson pine, sawtooth oak and maple). The loose and residual forest in Kuzhou area with such tree breeds as pinaster, fir, tung and tea-oil tree as the main is replaced by the timber forest with fir, masson pine and common sassafras as the main and the economic forest with the tung tree and tea-oil tree as the main. The virgin secondary forest of small group still exists in partial zone. There is few natural vegetation in subproject investigated are and affected area. According to the planning and statistics of public forest and commercial forest in Shimen County, currently, there is forest land of 30942mu in Chujiang Town of Shimen County, including timber forest of 15507mu, shrub of 15006mu, forestation land of 387mu and suitable forest land of 42mu. Additionally, there is protection forest of 19806mu, timber forest of 1601mu, and economic forest of 9535mu in the county seat. The vegetation in the suburbs includes plant in plot, scattered masson pine, grassplot, wasteland and abandoned land with small shrub intermixed. The natural vegetation was completely replaced by houses, commercial buildings, and roads around the urban area. The vegetation in urban area includes economic tree and landscaping tree. There is no record or report about the rare or endangered flora, or historical famous trees in the subproject investigated area and subproject affected area.

3. SCREENING OF POTENTIAL IMPACTS AND MITIGATION

3.1. APPROACH TO ENVIRONMENTAL SCREENING

This chapter assesses potential environmental impacts associated with the proposed Subproject and recommends appropriate mitigation measures where necessary. Potential environmental impacts are analyzed by examining the impact of each stage of the Subproject implementation on the natural and human environment. Each component identified as having the potential for negative impacts is assessed in detail, including a review of potential impacts, recommendations for appropriate mitigation measures, recommendations for additional environmental analysis (if required), and analysis of residual impacts, if any.

The environmental screening is based on:

– a review of Government of China (GOC) publications, scientific literature, and previous technical and environmental impact studies;

– a review of available information on the Subproject design;

– consultation with local subproject Project Management Offices (PMOs), Environmental Protection Bureaus (EPBs) and other agencies;

– relevant guidelines and policies of the Asian Development Bank (see Section 2.2);

– Study from TA social evaluation

– field visits and surveys.

The result of the screening of potential environmental impacts is summarized in Table 3-1.

3.2.1.2 RECOMMENDED MITIGATION MEASURES

The Shimen Subproject SPIA and Resettlement Plan (RP) have been prepared in accordance with the standards and requirements of the PRC Land Administration Law (1998) and the associated Hunan Provincial Implementation Decree (2000), as well as the ADB’s Policy on Involuntary Resettlement. All recommendations for compensation and resettlement presented in the SPIA and RP should be fully implemented. If done appropriately the relocation will provide an opportunity to improve current housing condition for the affected persons. Affected rural households will be moved a short distance to another site within their original villages.

A Shimen Subproject Facilities Siting Plan (FSP) should be developed which appropriately locates temporary worker camps, construction facilities, etc, so as to minimize social and environmental impacts. Emphasis should be placed on siting these facilities in areas that have minimal existing settlements and productive systems. The FSP should be submitted to the Shimen EPB for approval. If the plan indicates facilities are sited inappropriately and may result in excessive social impacts then the plan should be modified until Shimen EPB approval is obtained.

3.2.1.3 RESIDUAL IMPACT

During the project implementation process, the relocatees have been compensated and resettledbased on relevant polices and compensations. Implementation of the recommendations in the SPIA and the RP, and appropriate siting of the facilities should ensure that the living standards of the relatively small number of affected persons are maintained and/or improved, accordingly, the residual impact of the project is small.

3.2.2 AGRICULTURE PRODUCTION

3.2.2.1 POTENTIAL IMPACT

Project permanent farmland acquisition is 29.6 ha. The temporary land acquisition may also include some farmland. Although the amount of farmland being acquired is small there may be some decrease in income for the affected farmers.

3.2.2.2 RECOMMENDED MITIGATION MEASURES

All recommendations for compensation and resettlement presented in the Shimen SPIA and RP should be fully implemented.

The FSP should emphasize the appropriate siting of worker camps, construction facilities, etc, so as to minimize temporary farmland acquisition. The FSP should be submitted to the Shimen EPB for approval. If the plan indicates facilities are sited inappropriately and may result in unnecessary temporary farmland loss then the plan should be modified until Shimen EPB approval is obtained.

3.2.2.3 RESIDUAL IMPACT

As the project-affected area is located in the urban suburb, the rural economy is considerably active, the farmers have experiences in the secondary and tertiary industries. Therefore, relying on the geography and communication advantages, they will keep and improve the living

conditions by the individual commerce, service industry, and agricultural byproduct processing industry.

3.2.3 ECOLOGICAL RESOURCES

3.2.3.1 POTENTIAL IMPACT

The flood control embankment line land occupation, earth borrowing, waste soil and slag arising from the construction of the flood project will destroy vegetation in the original section, disturb the original earth surface, as well as produce new loss of water and soil. Based on the site investigation, there are few vegetations in the embankment-located section, with the scattered shrubbery and protection forest as the main part, material of the project mainly come from the barren hills, no mass forests, therefore, project construction will destroy the local vegetation little; in addition, destroyed vegetation would be restored by means of scenic forests along the river, protection forest, sodding protection, and other measures in the late stage of the project. Additionally, the project will protect the urban ecological environment in a certain degree, thus, various vegetations in the area will not be attacked by flood. Therefore, the potential impact of the project on the environment is considerably small.

3.2.3.2 RECOMMENDED MITIGATION MEASURES

1) Ecological protection for borrow yard: after exploitation of the soil material yard, the construction site should be scaling and leveled duly, meanwhile, the earth surface afforestation measures should be adopted, so as to ensure that it would restore to its original scenery or better improvement;

2) Ecological protection for spoil yard: in order to prevent landslip of slag or occupy cultivated land or roads, certain measures for prevention of loss of water and soil should be adopted;

3) Ecological protection for embankment works: during design and construction process of the embankment project, try to adopt the afforestation measures in combination with the demand of the urban scenic and ecological development to shape the flood control embankment project as an urban rivershore scenic belt.

The FSP should be submitted to the Shimen EPB for approval. If the plan indicates facilities are sited inappropriately and may result in serious impacts on any identified ecological resources then the plan should be modified until Shimen EPB approval is obtained.

3.2.3.3 RESIDUAL IMPACT

No significant residual impact is predicted.

3.2.4 HISTORICAL AND CULTURAL VALUES

3.2.4.1 POTENTIAL IMPACT

As there are no historical and cultural relics in the environment impact area of the component, no impact of the project on the historical and cultural relics.

3.2.5 TRANSPORTATION

3.2.5.1 POTENTIAL IMPACT

The building of the dike may cause some localized and short-term traffic disruptions.

3.2.5.2 RECOMMENDED MITIGATION MEASURES

The Public Roads and Transportation Administration Bureau should be consulted to ensure that access routes are not unduly affected and that if necessary alternative routes are provided that are sufficient to meet the needs of the affected persons.

3.2.5.3 RESIDUAL IMPACT

The transportation negative impacts will be minimal and short-term. No significant residual impact is anticipated.

3.2.6 MINERAL RESOURCES

3.2.6.1 POTENTIAL IMPACT

The Subproject will not cause the loss of mineral resources. The temporary land acquisition in the borrow pits and spoil area will have no significant effect on the exploitation of any identified or potential mineral resources.

3.2.7 PUBLIC FACILITIES

3.2.7.1 POTENTIAL IMPACT

The building of the dike project may affect some public facilities, including 1.0 km of high voltage line, 2.9 km of low voltage line, and 2.3 km of telecommunication line.

3.2.7.2 RECOMMENDED MITIGATION MEASURES

As part of the implementation of the civil works any affected public facilities will be replaced or repaired. In addition appropriate compensation should be provided to affected persons or enterprises.

3.3 CONSTRUCTION

3.3.1 HYDROLOGY

3.3.1.1 POTENTIAL IMPACT

The construction of the 15.574km of dikes and associated works along the both banks of the Lishui River will not involve any significant in-channel activities and will not cause any significant impact on the Lishui hydrology.

Dredging activities may have some very localized short-term impacts to hydrology, but overall will lead to increased flow capacity.

The construction of the drainage channels will not involve any Lishui River in channel activities and will not significantly affect the hydrology of the river.

3.3.2 WATER QUALITY

3.3.2.1 POTENTIAL IMPACT

Domestic sewage from temporary living quarters of construction workers will be collected centralizedly, after having been preliminarily process by the septic tank, wastewater after processing will be drained into the urban sewer networks. Wastewater containing sand produced during the project construction period will be deposited initially by the sedimentation tank, and then it will be drained into the urban sewer networks. Regarding Shimen flood control projects along the urban drinking water resources protective zone of counties and cities, the construction wastewater is forbidden to drain into the river course, after construction wastewater produced from the flood control project in this section has been processed initially, it will be drained into the urban sewer networks; as for flood control projects in other sections, the wastewater treatment could be carried out according to concentrated pollution sites, such as, electric drainage station and sluice, the areas for washing and repairing vehicles will be established concentratedly, after oil insulation treatment has been conducted to waste water and oil, they could be drained out of the city.

As Yangjialinggan waterworks of Shimen County is located at 300m place of Sanjiangkou dam at the upper reaches, after wastewater and sewage produced by project construction has been treated, they will be drained into the water intake lower reaches of the waterworks, accordingly, the impact of the project on safety of drinking water of residents in the county is not big.

3.3.2.2 RECOMMENDED MITIGATION MEASURES

A Shimen Subproject construction EMP will be developed which will specify best-practice construction phase water quality protection measures as follows:

Conservation of Water and Soil

Based on characteristics of each district, the engineering and plant measures are adopted for prevention respectively.

i) Main Project Area

During design of the main works, the measures of slope and bank protection, renovation of

Page 38: Initial Environmental Examination - adb.org · PDF fileInitial Environmental Examination June 2007

HUNAN FLOOD MANAGEMENT PROJECT

SHIMEN COUNTY INITIAL ENVIRONMENTAL EXAMINATION (IEE)

JUNE 2007 PAGE 30

drainage ditches, and sodding protection are considered for the embankment body, accordingly, the measures of conservation of water and soil of main prevention area is not required for the design.

ii) Spoil Area

Before piling, the drainage system around the spoil yard should be perfected, so as to prevent the surface being eroded by rainstorm or flood. Additionally, the retaining facilities are built in the spoil area.

During piling, the piling procedures should be strictly controlled, slag surface should be levelled by the tractor, and then be compacted 3~4 times by layers. The slope ratio of side slope of the spoil area should meet the stabilization requirement of the side slope of the spoil area, and the designed side slope of the spoil area will take 1:2.5.

After completing piling slag: carry out scaling, upgrading, and levelling to the spoil area, newly build the drainage ditch for the slag piling surface, and the surface of the side slope and spoil area should be protected with plants.

iii) Earth Material Yard Area

Regarding this works, earth of 0.5363 million m3 should be borrowed from the earth material yard,

3 earth material yards are planned to build, with a total area of 17.53hm2. For preventing loss of

water and soil in the earth material yard, the retaining ridge should be built outside of the earth material yard before exploiting it. In addition, the catchwater should be constructed at 3m place out of the top of the excavated slope surface, and the excavated surface should be spread with grass seeds after completing borrowing earth. The drainage ditches should be built on the excavated surface, and it should also be levelled, restored, or planted with soil and water conservation forest.

iv) Land Temporarily Occupied by Construction

The land occupation area is 4.34hm2. After completion, it should be levelled, and the soil and

water conservation forest should be restored. The species of trees is Yulan, with a density of plantation of 2500 trees/hm

2, and row spacing of 2×2.0m. In winter, the land should be levelled in

scrobiculalus, with a specification of 0.6×0.6×0.6m, and it will be planted in spring. The tree planting and afforestation method is adopted, and the perennial grade I seedlings are selected, water them duly after plantation. The “two-two-one” system is taken for the fostering mode, that is, breeding two times in the first year, and once in the second and third year respectively. The land with an area of 4.34hm

2 should be levelled, the water conservation forest of 4.34 hm

2

should be established, with 10850 trees in total.

v) Temporary Construction Road

The temporary road of 4000m should be built in the project, after completion of the project, it would be used as the rural roads. In the main works, the macadam hardening measures for the pavement and the drainage measures for both sides of the subgrade have been considered. In the design, the sodding protection measures would be taken for inner excavated slope surface and outer filling slope surface of the road, and the slope surface needs the sodding protection of 6500m

2.

vi) Resettlement Area

148 households of 464 persons should be relocated in the project. The resettlement of building houses occupies land of 2.24hm

2. The gardening and afforestation of 1.42 hm

2 is planned for the

district. In addition, the mode combining arbores, shrubberies, and grasses is adopted. The green trees and lawns will be built around the living quarters of the relocatees, together with the scenic forests, shrubberies, and flowers, a natural living space characterized by warm, harmony, and beautification will be forged for all relocatees.

Construction Wastewater Control

HUNAN FLOOD MANAGEMENT PROJECT

SHIMEN COUNTY INITIAL ENVIRONMENTAL EXAMINATION (IEE)

JUNE 2007 PAGE 31

- Wastewater from concrete washing and curing should only be directed to the local sewer system or local drainage channels near the construction site and not directly to the Lishui River.

- Wastewater containing sand produced during the project construction period will be deposited initially by the sedimentation tank, and then it will be drained into the urban sewer networks and local drainage channels, it is forbidden to drain it into Lishui River directly;

- Water from vehicle and equipment washing should be directed to the local sewer system or local drainage channels near the construction site and not directly to the Lishui River. Oils should be removed first as much as practical.

- Receiving drainage ditches should be equipped with a bioswale and siltation traps prior to their discharge to any major receiving water body.

Sewage - Temporary toilets will be provided at a rate of 1 for every twenty workers. - All domestic wastewater from the workers camps should be discharged to the municipal

sewerage system. - On-site sewage will be collected as necessary by the Shimen Health and Sanitation

Company and treated or discharged to the municipal sewerage system. - Regular cleaning and disinfection of the toilets should be undertaken so as to avoid

breeding of flies and mosquitoes.

Safety - Best practice on and off site safety practices to be implemented, including limiting vehicle

speeds, fencing unsafe sites, etc.

3.3.2.3 RESIDUAL IMPACT

With the implementation of appropriate mitigations measures the impact on water quality will be limited.

3.3.3 SOLID WASTE

3.3.3.1 POTENTIAL IMPACT

The solid waste during construction period mainly includes construction slag and domestic rubbishes, construction slag mainly comes from temporary piling of earthwork in the foundation excavation, slag mainly includes mud, sand and stone, etc. The Sunjiabao and Yangmingshan spoil areas are established in two protective zones in the project, and the total planned area of the spoil area reaches about 12.09hm

2. During construction process, if construction slag is piled

randomly, serious loss of water and soil will be produced, accordingly, the protection measures should be adopted for the spoil area, effectively control loss of water and soil of the spoil area by means of combination of project and plantation, so as to prevent environmental pollution.

The domestic rubbishes of the construction area are considerably small, there are 712 construction workers during the construction peak, calculate based on the daily rubbish production capacity of 0.5kg per capita, the daily highest production capacity is 356kg. If domestic rubbishes are piled randomly, they will not only affect the scenery, but also pollute the air, in certain climate, mosquitoes, flies, and rats will largely breed, therefore, they will diffuse various diseases among construction workers. In order to prevent environment being polluted by domestic rubbishes, domestic rubbishes should be piled concentratedly, special persons should be appointed to clearly, fill, and bury them periodically.

3.3.3.2 RECOMMENDED MITIGATION MEASURES The EMP will specify waste management procedures as follows:

Page 40: Initial Environmental Examination - adb.org · PDF fileInitial Environmental Examination June 2007

HUNAN FLOOD MANAGEMENT PROJECT

SHIMEN COUNTY INITIAL ENVIRONMENTAL EXAMINATION (IEE)

JUNE 2007 PAGE 32

Spoils From Earthworks - Maximum use should be made of on site excavated materials so as to minimize spoil

production - The disposal sites should be identified in the FSP, and should not be in or near any

sensitive areas. - Spoil disposal should only be allowed in designated sites. - Erosion protection measures such as silt fences and covering the spoil mounds should be

implemented. - Upon completion of construction the spoil deposits should be re-vegetated with appropriate

native grasses and shrubs.

Construction Wastes and Rubble - Maximum use should be made of construction rubble as fill where/ if appropriate. - Rubble should only be stored on sites temporarily, and should be land filled if space is

available, or disposed of in a designated construction waste disposal site as approved by the Shimen EPB.

Dredgate - The dredgate disposal sites should be identified in the FSP, and should not be in or near

any sensitive areas. - Disposal should only be allowed in designated sites. - Erosion protection measures such as silt fences and covering the spoil mounds should be

implemented. - Upon completion of construction the spoil deposits should be vegetated with appropriate

native grasses and shrubs.

Domestic Waste - Waste containers will be provided in certain spots at a rate of 1 for every twenty workers. - Domestic solid waste produced by construction workers must be deposited into waste

containers. - Collection and disposal of domestic solid waste will be undertaken by the Shimen Health

and Sanitation Company. Waste disposal will only be allowed at the Shimen domestic solid waste deposit site.

3.3.3.3 RESIDUAL IMPACT

No significant residual impact is predicted.

3.3.4 AIR QUALITY

3.3.4.1 POTENTIAL IMPACT

The primary atmospheric pollutants generated during construction are dust and particulate matter produced during vehicle transport, cement mixing, and wind-generated soil erosion; and emissions from transport vehicles and heavy machinery, dust from vehicle transportation and tail gas produced by the fuel machinery.

Compared with construction situation of similar projects, road dust pollution from vehicles will be diffused from both sides of the road mainly, when the subgrade is 3m higher than the ground, the max. dust appears at both sides of the road. With increased distance away from the roadside, the concentration will decrease gradually and tend towards the background value, in general conditions, the affected area is within 30m at both sides of the roadside. Area affected by dust from cement mixing and dust pile will be determined by grain size of materials, wind direction, and wind power. The main pollutants in construction vehicle emissions include NO2, CO, and SO2, the tail gas discharge belongs to a surface source one, the discharge capacity of its

Page 41: Initial Environmental Examination - adb.org · PDF fileInitial Environmental Examination June 2007

HUNAN FLOOD MANAGEMENT PROJECT

SHIMEN COUNTY INITIAL ENVIRONMENTAL EXAMINATION (IEE)

JUNE 2007 PAGE 33

contamination is considerably low, the impact of tail gas on the local atmospheric environment is considerably small.

The impact of dust and tail gas on the atmospheric environment of the district will be affected by the climate largely. Based on the overall layout of the project construction, the conveyance lines and project construction are mainly distributed along both banks of Lishui River. As the project is mainly constructed in the low-water period, that is, summer, impacted by the wind direction, the air pollution due to construction of the flood control project will bring a certain adverse impact on air quality of Dongcheng district and Baofeng district near the construction area.

3.3.4.2 RECOMMENDED MITIGATION MEASURES

The transportation roads within the construction site should be hardened, and the transportation roads within the construction site and the surrounding urban area should be regularly sprayed with water so as to control dust. Truck loads should be covered with an awning to prevent dust emissions.

The cement transport and mixing process should be carried out under closed conditions. Cement should be transported by closed tankers, and should be conveyed to the concrete mixer by a closed cement pump.

Soil piles should be covered unless being actively used. Piles should be sprayed with water when not covered. Spoil piles should also be covered unless being actively used, and should be sprayed with water when not covered.

For construction of dikes close to dense residential areas fiber texture protection fences should be installed on the urban side of the dike to reduce air and noise pollution.

All construction machinery and transportation vehicles should be equipped with exhaust emission systems that meet relevant PRC emission standards. Vehicle emission systems should be inspected at construction outset and then on a bi-annual basis.

3.3.4.3 RESIDUAL IMPACT

Few significant residual impacts are identified after implementation of the measures.

3.3.5 NOISE

3.3.5.1 POTENTIAL IMPACT Noise will be generated during the construction period from machinery and conveyance vehicles, such as, excavators, bulldozers, loaders, concrete mixers, and other large-scale conveyance vehicles according to the project scale, construction strength during the peak, the complex sound level of noise from the construction site is about 80dB (A) generally. Based on the Class II Standard (the continuous equivalent sound level in A scale shall not exceed 60 dB in the daytime and 50 dB in the night time) as specified in The National Standards for Environmental Noises in Urban Areas (GB 3096-93), the impact of the project on the adjacent environment will be evaluated. Obviously, the noise from the construction process exceeds the standards, which will negatively impact schools and residential areas close to the construction sites. Construction noises during the construction period include mechanical construction noise and conveyance vehicle noise, main construction machinery and conveyance vehicles include bulldozer, concrete mixer, and large-scale conveyance vehicles. Based on the project scale, the sound level arising from the construction intensity during the peak and noise from the construction site is about 80dB (A) generally. The impact of construction noises on the residential area could be predicted by the decline mode by the distance of the point sound source in the free

Based on the site investigation, residential areas and units are concentrated near the project construction area, with a distance between the worksite of 30~200m. As the distance between the embankment is short, noises in daytime and night all exceed limits, accordingly, corresponding measures should be adopted to manage and control noises, so as to reduce adverse impact of construction noise on residents.

In addition, construction noises will largely impact construction workers, accordingly, during construction, the construction unit should try to reasonably allocate the construction machinery, adopt corresponding measures for sound insulation and sound absorption, and take labour protection for construction workers.

3.3.5.2 RECOMMENDED MITIGATION MEASURES

Noise from Transport Vehicles - vehicle overloading is prohibited; - horn operation in urban areas is prohibited; and - all vehicles should have functioning mufflers that meet relevant standards.

Noise from Heavy Machinery - all construction machinery should be in full compliance with the PRC Standards of

Environmental Noise of Urban Areas (GB3096-93); - low noise construction methods should be adopted wherever possible; - regular maintenance of machinery should be undertaken to reduce operational noises. - construction personnel working in high noise level situations should be provided with

protective equipment and should not work continuously in such situations for more than 6 hours per day.

Dike Construction: - construction of dikes in urban areas is prohibited between from 10:00 pm to 6:00 am daily; - in areas that are particularly sensitive to noise (e.g. within 200 m of schools and hospitals),

structural measures such as sound separation walls should be implemented. Compensation for high noise levels may also be required.

HUNAN FLOOD MANAGEMENT PROJECT

SHIMEN COUNTY INITIAL ENVIRONMENTAL EXAMINATION (IEE)

JUNE 2007 PAGE 35

3.3.5.3 RESIDUAL IMPACT

With the implementation of the mitigation measures the residual impacts are localized and relatively short term.

3.3.6 FLORA

3.3.6.1 POTENTIAL IMPACT

In terms of investigation, within area affected by project construction, the ground plant is the economic crop generally, and some weeds and shrubberies are on the wasteland, no native vegetation and rare plants are distributed in the area affected by the project construction. Large part of the project construction area will occupy shrubbery and wasteland temporarily, as the subproject area has high rainfall, a good climate and comparatively good soil quality that is favourable for vegetation growth it is anticipated that re-vegetation of spoil areas will not be difficult. Based on experience with similar water resources projects, supported 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 Shimen County Urban Flood Control Project could 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.

3.3.6.2 RECOMMENDED MITIGATION MEASURES

As noted previously an FSP will be developed and submitted to the Shimen EPB for approval. If the plan indicates facilities are sited inappropriately and may result in impacts on any identified precious ecological resources then the plan should be modified until Shimen EPB approval is obtained.

Excavated materials should be used as much as possible as fill in the construction in order to reduce the quantities of spoil and the size of the spoil deposition sites. Spoil should only be disposed at sites designated in the FSR.

Compensation vegetation should be planted at all suitable locations. Specifically: - native grasses should be planted along dikes slopes in order to provide slope protection; - all borrow pit areas should be fully re-vegetated with appropriate native species of grass,

shrubs or trees in order to replicate local natural vegetation cover; - all spoil disposal sites should be fully re-vegetated with grasses, shrubs or trees in order to

replicate local natural vegetation cover;

3.3.6.3 RESIDUAL IMPACT

With the implementation of the mitigation measures the residual impacts from permanent land occupation are small, localized and long-term, and residual impacts from temporary land occupation are small, localized and relatively short term.

HUNAN FLOOD MANAGEMENT PROJECT

SHIMEN COUNTY INITIAL ENVIRONMENTAL EXAMINATION (IEE)

JUNE 2007 PAGE 36

3.3.7 FAUNA

3.3.7.1 POTENTIAL IMPACT

As noted above the Subproject will permanently occupy 279.13 mu of land, of which, cultivated land is 171.8 mu. These areas are within an urbanized or semi-urbanized landscape, and do not contain significant areas of animal habitat or any rare or endangered fauna. The only impact will be on a limited area of habitat and feeding grounds for reptiles and rodents and small animals.

3.3.7.2 RECOMMENDED MITIGATION MEASURES

As noted previously an FSP will be developed and submitted to the Shimen EPB for approval. If the plan indicates facilities are sited inappropriately and may result in impacts on any identified precious ecological resources then the plan should be modified until Shimen EPB approval is obtained.

Vegetation on land that is temporarily occupied (e.g. borrow pits, spoil disposal sites, etc) will be replanted, replacing the habitat that is lost.

3.3.7.3 RESIDUAL IMPACT

With the implementation of the mitigation measures and given the limited local animals and plants the residual impacts from permanent land occupation are small and localized.

3.3.8 AQUATIC LIFE

3.3.8.1 POTENTIAL IMPACT

The relevant reaches of the Lishui River contain little moderate or good quality aquatic habitat, and there are no reports of economically important fishing activities or rare and endangered aquatic life. If the project erosion and pollution control measure are implemented properly there will be little or no impacts on aquatic life in the Lishui from the construction of the dikes and associated works.

3.3.9 PUBLIC SAFETY

3.3.9.1 POTENTIAL IMPACT

The establishment of the worker camps poses public health safety risks through infectious disease propagation if sanitation (sewage and solid waste management) is not appropriate. For example, as noted previously, a lot of domestic solid waste will be generated during the construction period. This will be produced over a large area, and if not collected and disposed of appropriately will result in a reduction in overall environmental quality.

3.3.9.2 RECOMMENDED MITIGATION MEASURES

A Health and Safety plan will be developed that will specify the Health and Safety obligations of the contractor.

Health of Workers

Page 45: Initial Environmental Examination - adb.org · PDF fileInitial Environmental Examination June 2007

HUNAN FLOOD MANAGEMENT PROJECT

SHIMEN COUNTY INITIAL ENVIRONMENTAL EXAMINATION (IEE)

JUNE 2007 PAGE 37

- Workers should be healthy and free of infectious diseases when joining the construction phase.

- Any worker who develops an infectious disease should receive adequate medical care, and should be quarantined during the infectious period.

- Any disease out break shall be reported to the relevant health authorities immediately. All instructions issued by the health authorities to deal with the outbreak shall be immediately implemented.

- Workers must be provided with protective gear as required by the PRC Labor Law (1994) and relevant Hunan provincial regulations.

- The maximum working shift is 8 hours per day. - In high noise conditions a maximum of 6 hours per day only is permitted.

Domestic Rubbish: - Domestic solid waste produced by construction workers must be disposed into waste

containers. - Waste containers should be provided at a rate of 1 for every twenty workers. - Collection and disposal of domestic solid waste will be undertaken by the Shimen Health

and Sanitation Company. Waste disposal will only be allowed at the Shimen landfill site.

Sewage - Temporary toilets will be provided at a rate of 1 for every twenty workers. - Sewage will be collected as necessary by the Shimen Health and Sanitation Company and

treated or discharged to the municipal sewerage system. - Regular cleaning and disinfection should be done so as to avoid breeding of flies and

mosquitoes.

3.3.9.3 RESIDUAL IMPACT

With the implementation of appropriate mitigations measures the negative public safety impacts will be minimal. The positive health and safety impacts of the flood protection provided by the Subproject will be significant and long-term.

3.4 OPERATION

3.4.1 HYDROLOGY

3.4.1.1 POTENTIAL IMPACT

An analysis was undertaken of the water surface profile through Huaihua with and without the new dikes and other civil works (Table 3-3). The analysis shows that with the inclusion of dikes to prevent the city from being flooded with a 1 in 20 year return period event the actual change in the water surface profile is very small (maximum 0.25 m). The main reason for such a small change is because the Lishui River section at Shimen is wide and the dikes will be set approximately 420 m apart. Although without dikes the flood would spread into the city flood plain, the volume of discharge through the city area is small when compared against the majority of discharge that remains in the river channel. Therefore, the dike operation will not have a significant impact upon flood discharge or water surface profile levels. However, operation of the dykes and other civil works will lead to a significant reduction in flooding in the Subproject flood protection zones.

3.4.2 WATER QUALITY

3.4.2.1 POTENTIAL IMPACT

Overall operation of the Subproject will not produce any pollutants and will not bring about any negative impact on the quality of the urban waters. Further, implementation of the Subproject will improve the flood control standards and drainage capacity of Shimen, which will reduce ecological damages and water pollution that occurs during urban flood events.

3.4.3 FLORA AND FAUNA

Operation of the Subproject will not negatively impact flora or fauna. Re-vegetation of temporary sites impacted during the construction phase will take three to five years, so will extend in to the operation phase, but these are not new impacts and have been addressed previously.

Implementation of the Subproject will protect the urban ecological environment, shielding flora and fauna within the protection zone from flood associated damages.

4 PUBLIC PARTICIPATION

4.1. BENEFICIARY IDENTIFICATION

The major beneficiaries of the proposed Shimen Flood Control Subproject will include urban residents, rural village residents, enterprises, government institutions, and businesses. There is an estimated 34,786 people in the flood protection zone who will directly benefit.

4.2. PUBLIC CONSULTATION

Table 4-1 summarizes the public consultation activities that have been undertaken.

During the social surveys small group discussions were held among groups of individuals in select communities. Based on their experience individuals identified a range of benefits to be brought by the Subproject, summarized in Table 6-2. A range of potential negative impacts to be brought by the proposed Subproject were also identified. Of these land acquisition, demolition of houses and relocation of people were considered the major negative impacts of the Subproject. However, as most participants did not have a clear idea about the Subproject and its related potential land acquisition and resettlement impact, they were unable to express their concerns with regard to potential negative impacts. It is recommended that during next stage of Subproject preparation more meaningful participation and disclosure should be carried out in order to improve basic understanding of the Subproject and address concerns raised by the Subproject affected people.

Overall, all focus groups, including both urban and rural populations, expressed positive attitudes towards the proposed Subproject. Of the 95 individuals interviewed no one expressed opposition to the Subproject.

6. FINDINGS AND RECOMMENDATIONS

6.1. FINDINGS

The Shimen County Subproject will result in both socio-economic and environmental impacts.

The socio-economic impacts are primarily related to the construction-phase resettlement. The permanently- occupied land will be in 2 conservation districts: Dongcheng District, Baofeng District and 45 groups of 12 villages in 4 towns: Chujiang Town, Baofeng Development District, Erdu Village and Yijiadu. Farmland acquisition will affect a total of 148 households and 464 persons. A total of 23135m

2 of buildings will be demolished. 279.13 mu will be occupied, which

includes 171.8mu of farmland. Approximately 557.5 mu of land will be occupied temporarily during the construction phase, which affects partly electric power, telecommunications, and broadcast television.

A Shimen Subproject Social/Poverty Impact Assessment (SPIA) and a Resettlement Plan (RP) have been prepared in accordance with the standards and requirements of the PRC Land Administration Law (1998) and the associated Hunan Provincial Implementation Decree (2000), as well as the ADB’s Policy on Involuntary Resettlement. All recommendations for compensation and resettlement presented in the SPIA and RP should be fully implemented. If done appropriately the relocation will provide an opportunity to improve housing conditions for the affected persons.

Construction of the project is not anticipated to have any significant terrestrial ecological impacts as the project area is generally a heavily modified urbanized/rural farmland mosaic and no sensitive terrestrial resources or rare and endangered flora and fauna have been identified in the Subproject Environmental Impact Area (SEIA). Dike construction will not affect hydrology of the Lishui River. Erosion from construction sites and source rock and soil piles as well as other construction pollution sources may reduce water quality in the Lishui River, as will dredging. Dredging will have to be implemented carefully to minimize impacts. Other potential impacts include solid waste and noise pollution issues during construction, especially in the urban areas. Overall however, environmental impacts are localized and temporary, and can be adequately mitigated.

Operation of the Shimen dikes will have no significant negative impacts on the Lishui River water level, water quality, or on terrestrial or aquatic flora and fauna.

The main impacts that require special measures are associated with the construction phase, including:

- soil erosion and runoff from exposed earthwork sites;

- the rehabilitation of borrow areas and spoil sites;

- construction wastewater and domestic wastewater from construction camps;

- construction solid wastes and domestic waste from construction camps;

Page 72: Initial Environmental Examination - adb.org · PDF fileInitial Environmental Examination June 2007

HUNAN FLOOD MANAGEMENT PROJECT

SHIMEN COUNTY INITIAL ENVIRONMENTAL EXAMINATION (IEE)

JUNE 2007 PAGE 64

- air pollution from traffic and construction site dust;

- noise pollution from construction activities and heavy machinery;

- dredging; and,

- Public safety.

A comprehensive program of mitigation measures, environmental motoring and compliance inspections has been designed to address these issues. The estimated budget for environmental protection and monitoring during the construction stage is US$ 283,007 (CNY 2,343,300). If the mitigations are appropriately implemented the project should have minimal negative impacts and should result in overwhelming positive benefits brought about by the flood protection it will provide.

6.2. RECOMMENDATIONS

1. All resettlement and compensation recommendations in the SPIA and the RP should be strictly followed.

2. All mitigations recommended in this report and in the stand-alone EMP should be implemented.

3. The training and capacity building recommended in this report and in the stand-alone EMP should be implemented.

4. The environmental monitoring and compliance inspections recommended in this report and in the stand-alone EMP should be implemented.

7. CONCLUSION

The Shimen County Subproject will improve flood protection in the Shimen urban area through the construction of dikes, drainage works and river dredging.

The most significant socio-economic impacts are primarily related to the construction-phase resettlement. All recommendations for compensation and resettlement presented in the SPIA and RP should be fully implemented. If done appropriately the relocation will provide an opportunity to improve housing conditions for the affected persons.

Potential environmental impacts are associated with construction phase solid and liquid wastes, noise and air pollution and dredging. Negative environmental impacts are generally localized, short-term, and can be fully mitigated or minimized.

A range of mitigation measures has been recommended to address the environmental issues raised in this report. The mitigations relate to the rehabilitation of borrow areas, control of soil erosion and runoff from earthworks, prevention of water, air and solid waste pollution, reduction of impacts from dredging, noise reduction and public safety. The estimated budget for environmental protection and monitoring is US$ 283,007 (CNY 2,343,300).

A separate and stand alone environmental management plan (EMP) is being developed which will guide the implementation of the recommended mitigation measures; present an environmental monitoring program; facilitate institutional arrangements for the implementation of mitigation measures and the environmental monitoring; and, ensure compliance with the environmental requirements of the People’s Republic of China (PRC) and the Asian Development Bank (ADB).

With the implementation of the recommended mitigation and monitoring measures the Subproject is not expected to have any significant negative environmental impacts. Overall the flood protection provided by the Subproject will significantly enhancing the safety and quality of life of the residents living and working in the protection zones.

Given the limited environmental impacts identified in this IEE the Subproject’s tentative designation as Category B under the ADB’s environmental guidelines has been confirmed. As no significant residual environmental impacts are expected, and all minor impacts predicted during construction and operation can be fully mitigated, no additional studies or EIA is required.
