Executive Summary

1. The road condition in Bihar is very poor in terms of coverage and riding quality. The road density in Bihar is only 901 kilometres (km) per million persons compared with the national average of 2,567. About half of the villages lack all-weather road connectivity. Most roads suffer from poor geometry, weak pavement, inadequate capacity, and coupled with lack bridges causes high transport cost and excessive travel time.

2. With the above background, Government of Bihar (GOB) launched an ambitious plan to undertake the State Highway Development Program to rehabilitate and upgrade state highways (SH) to at least two lanes and expand the network by upgrading major district roads (MDR) to two lanes with funding support from Asian Development Bank (ADB). In the first phase, 820 kms of key state highways are now in the final stages of implementation. In the second phase, GOB has initially approached ADB for financial assistance for improving another 4 state highways, namely: SHs78, 81, 90, and 91 with an aggregate length of 173 kms under Bihar State Highways II Project (BSHP II) which was processed for implementation in 2010. During Phase II implementation, prudent financial management has resulted to substantial savings enough to take up another road, SH-89: Siwan-Siswan, which is the subject of this environmental assessment. The Phase II also includes the institutional strengthening of the road sector under separate TA (IND 7130) which will enhance EA‟s capacity for road asset development and management. The road sections details under BSHP II are given in Table 1.

3. The proposed upgrading of the State Highway-89:Siwan-Siswan is located in Siwan District of Bihar. It starts from Aradia Chowk at Siwan on NH-85 and terminates at Siswan where it meets on Tejpur-Majhi-Siswan-Barauli MDR. The total length of the sub-project road is 33.065 km. The subproject is in addition to the 4 state highways under the Bihar State Highways II Project (BSHRP II) which was processed and started implementation in 2010. The Project also includes the institutional strengthening of the road sector under separate TA (TA 7130-IND) which will enhance EA‟s capacity for road asset development and management. Key upgrading components involve the widening of existing intermediate lane road into a 2-lane road with paved shoulders of 1.5m on both sides, improved road geometry, proper and adequate embankment, rehabilitate and construction of new cross drainage structures and side drains, improve juctions/intersections, bus bays, and improved road safety

4. The sub-project‟s environmental impacts were screened using the ADB‟s environmental guidelines and was classified as Category-B consistent with the requirements of ADB Safeguard Policy Statement (2009). The screening of impacts revealed the road section does not pass through or located near any national park, wildlife sanctuary, reserved forests, or any other ecologically sensitive or protected areas. No archaeological/protected monument is located in the project vicinity. All significant impacts are site-specific and co-terminus with the construction phase. The road section, with the exception of two by-passes, are existing alignments and these are proposed to minimize social impacts. The only irreversible impact is the change in landuse along the ROW due to the double-laning of the road section. No significant adverse environmental impacts are anticipated. The Bihar State Environmental Impact Assessment Authority (SEIAA) approved the Bihar State Road Development Corporation‟s, Ltd. (BSRDC) request for exemption from the EIA Notification during its 13.02.2012 meeting since the road section is not located above 1,000 meters above mean sea level and does not pass through notified sanctuaries and parks.

5. The overall terrain is wholly in flat terrain with gradual rise in ground elevations from south to north. Road elevations vary from ground level to typically 1.5 metres. It passes through mostly rural areas. Land use on the project corridor constitutes 45% of urban to semi-urban type with residential and commercial uses while the remaining 55% is under agricultural use. The overall terrain is predominantly flat throughout the stretch. Important settlements along the project road are Siwan, Surapur, Chhapiya, Gopalpur, Sahuli, Nawada, Hasanpura, Jalalpur, Simri, Rajjanpura, Madhawapur, Rampur, Bhagwanpur Ghurghar, Chandpur and Siswan.

6. The Daha River is instrumental for water stagnation in low-lying area due to backwater flow/over flow from the river. The water carrying capacities of the River have reduced over time due to siltation resulting in floods in the basin. The flood affect the subproject road from Hassanpura area up to Ghurghut including the Chainpur main market area.

7. The economy of Bihar is agricultural and service oriented. Bihar has the lowest GDP per capita in India between 1999 and 2008; GDP grew by 5.1% annually, which was below the Indian average of 7.3%. More recently, Bihar's state GDP recorded a growth of 18% in 2006-2007, and stood at 942,510 crores rupees (US $21 billion) which makes Bihar one of the fastest growing major states. About 85% of state's population are dependent on agriculture and allied activities. The major crops of Bihar are: paddy, wheat, lentils. Bihar is also the leading producer of cash crops like tobacco, chillies, turmeric, oilseeds, sugar, and jute. It produces some of the finest varieties of mangoes, litchis, guavas, sapotas, citrus, pineapples and bananas. Bihar is the largest honey producer of India. The state is distinguished as the "Rice Bowl" of East India accounting for 6%, 6%, 11% and 9% share of rice, wheat, maize and jute produced in India, respectively. The major industries located in the area are mainly sugar factories, thermal power station, wagon factory, and pharmaceutical. Small scale industries include saw mill, rice mill, suji (sweets) factory, beverages, cold storage, and plywood. There are no major industries in the sub-project area.

8. The total population of Bihar is 82.8 million, third most populous state in the country. The sub-project district contributes nearly 9 % of the state population. Health facility in the state is weak. Among the project districts, Patna being the state capital, the health care facilities is comparatively better than Nalanda. More than 30% of the hospitals/dispensaries of the state are located alone in Patna. The overall literacy rate of Bihar is 47.53%, which is significantly low compared to country‟s literacy rate of 65.38%.

x

There is also a disparity among male and female literacy with 60.32% and 33.57% respectively. Among the project districts, Patna has the higher literacy rate of 63.4% the highest in the state while Nalanda ranks ninth. Of the total population of 82.88 million people, roughly 28 million people (34% of the population) comprise the workforce in the State. Migration is crucial survival strategy for the rural poor in Bihar. Based on census and National Sample Survey reports, Bihar has the highest rate of gross interstate migration in India. Tribal population in the project area is insignificant. There are no structures or sites of historical, archaeological, paleontological, or architectural significance.

9. All pre-construction, construction, and operation activities that were likely to cause environmental impacts were identified, and evaluated to assess their magnitude, duration, and potential receptors in consultation with the stakeholders. Consultations were made with the government representatives (District Forest Office, State Pollution Control Board, Water Resources Department, Directorate of Economics and Statistics, and the District Rural Development Authority), local communities (Chaata, Chainpur, and Ghurghut), and NGOs (Hassanpura Vikash Manch, Socio Economic Development Society Siswan, Chainpur Vikash Parisad) between March to June 2009.

10. Sections of the SH-89 are prone to flooding particularly near Daha River. Submergence is mainly due to reduced river capacity in the area coupled with drainage congestion.

11. An estimated 972 trees will be cleared needing forest clearance from the Forestry Department. This will be mitigated, among others, through a 1:3 compensatory plantation scheme.

12. The significant impact during construction is mainly associated with minor increase in dust borne air pollution, increased noise level, nuisance due to movement and operation of vehicles, establishment of temporary facilities, hindrance in accessibility to common property resources etc. During operation stage the main impact may be on the surface water hydrology since the construction of a road across several river/rivulets in the flood affected sections can act as impediment to natural flow of water. Other issues relates to road safety including pedestrian and cattles.

13. Other than the permanent change in land use, all identified impacts are short-duration and co-terminus with the construction phase, and are easy to mitigate. All private lands that will be converted, including structures that will be relocated will be justly compensated in compliance to existing laws.

14. In general, the sub-project received immense support from local people with some concerns and apprehensions related to compensation for land and structures. The local people appreciated that besides providing an all weather efficient connectivity to large population and improving the traffic scenario in the region, it will bear out several other positive economic and social benefits which outweights the negative environmental impacts.

15. This initial environmental examination (IEE) ascertains that the sub-project is unlikely to cause any significant environmental impacts. Few impacts were identified attributable to the proposed sub-project, all of which are localized and temporary in nature and can be easily mitigated with minor to negligible residual impacts. No additional studies or need of undertaking detailed EIA is envisaged at this stage.

1. INTRODUCTION

A. Project Background

1. Bihar is one of the economically backward states of India. Judged by the per capita state income of Rs9,765 in the FY2007, Bihar ranks far below the all India average of Rs33,299. The road network in Bihar is very poor in terms of coverage and conditions while demand for road transport is increasing. The road density in Bihar is only 861 km per million population, compared with the national average of 2,828 km. About half of villages lack all-weather road connectivity. Insufficient funding for road maintenance in the past has increased the number of roads beyond maintainable condition.

2. Poor quality of the road infrastructure is one of the major factors constraining the socio-economic development of Bihar. Rapid development and strengthening of the road network will provide momentum in accelerating economic development of the state, enabling Bihar to move from being dependent on subsistence farming to focusing on market-oriented agriculture and tourism. Since Bihar is the third most populous and poorest state in fast-growing India, development of the state is equally important for the country‟s goal of regionally balanced growth.

3. With the above background, Government of Bihar (GOB) launched an ambitious plan to undertake the State Highway Development Program to rehabilitate and upgrade state highways (SH) to at least two lanes and expand the network by upgrading major district roads (MDR) to two lanes with funding support from Asian Development Bank (ADB). In the first phase, 820 kms of key state highways are now in the final stages of implementation. In the second phase, GOB has initially approached ADB for financial assistance for improving another 4 state highways, namely, SHs78, 81, 90, and 91 with an aggregate length of 173 kms under Bihar State Highways II Project (BSHP II) which was processed for implementation in 2010. During Phase II implementation, prudent financial management has resulted to substantial savings enough to take up another road, SH-89: Siwan-Siswan, and considered as the fifth package in BSHP-II. BSHP –II also includes the institutional strengthening of the road sector under separate TA (IND 7130) which will enhance EA‟s capacity for road asset development and management. The road sections details under BSHP II are given in Table below.

B. Executing Agency

4. Executing agency (EA) for the project is Bihar State Road Development Corporation Limited (BSRDC). Road Construction Department (RCD) is the parent organisation responsible for construction and maintenance of roads on behalf of GOB.

2

GOB has recently setup the BSRDC to streamline decision-making and provide more autonomy for project execution and delivery. All powers, functions, and accountability of road agencies in the state have been redefined.

C. Technical Assistance for Environmental Safeguard

5. ADB fielded TA 7773-IND to assist BSRDC in project preparation for possible financing of Additional Financing BSHP. As a part of this TA and safeguard requirement of ADB, environmental assessment has been carried out in accordance with relevant country‟s applicable laws, regulations and in consistent to ADB‟s Environmental Assessment Guidelines, 2003 and Safeguard Policy Statement (SPS), 2009.

6. The present report pertains to Siwan-Siswan (SH-89) sub-project. It has been categorized as Category ‘B’ and hence an initial environmental examination (IEE) has been conducted.

D. Purpose of the Study

7. The purpose of the study is to identify the environmental issues to be considered at project planning and design stages, assess environmental consequences due to project intervention, and suggests measures to avoid, minimize, or mitigate the adverse environmental impacts, if any, associated with construction and operation.

E. Extent of IEE

8. The IEE was conducted based on the most up-to-date detailed project report. Certain changes may occur in the subproject structural components but these changes are unlikely to cause significant environmental impacts. The IEE covered all activities proposed under the project. The core zone of impact is taken as 100 meters either side of the alignment. However, the study area is considered up to 7 km on either side of road alignment for larger analysis of landuse and other environmental features. Assessment is carried out for all components of environment covering terrestrial and aquatic ecology, soil, water, noise and socio economic aspects.

F. IEE Content

9. The IEE has been largely structured in compliance to the ADB Safeguard Policy Statement (SPS) 2009 and ADB’s Environmental Assessment Guidelines (2003). This includes following eight Chapters including this introduction chapter.

3. DESCRIPTION OF THE ENVIRONMENT OF THE PROJECT AND SUB-

PROJECT

A. Project Location

15. The sub-project road section SH-89 is located in Siwan District of Bihar and connects Siswan on Chapra-Manhji, Darauli, Guthani Road in Siwan District. The total length of the sub-project road is 33.065 km. The location map of Bihar State Highway Projects II and sub-project location is given as Map 1.

1. Characteristics of the Existing road

16. Right of Way: The existing right of way along the whole stretch ranges between 8 to 22 m and is generally concentric with the centre line of the existing road.

17. Carriageway and Pavement Conditions: Carriageway width is varies from 3.0 m to 5.5m with 1m unpaved shoulder on both sides. Carriageway condition is mainly poor along various section measuring 18 kms to fair the remaining 16 km while riding is in fair condition for 20 km length. For remaining stretch, the pavement condition is poor and has developed fine to medium cracks. The pavement is mostly single/ intermediate lane with 1 m wide earthen shoulder exists along the project road except some reaches. Average speed traversing the entire stretch is only 20-25 kph.

18. Horizontal and Vertical Alignment: The horizontal alignment of the existing road has several sub-standard and sharp curves including reverse S-curves. There is no proper transition length for most of the horizontal curves including the reverse ones to provide for required super elevation reversal for riding safety and comfort. These deficiencies have been corrected by fixing the horizontal alignment for the entire project road to conform to MoSRT&H standards. The vertical alignment of the road is at a flat grade with the height of embankment generally varying from 0.50 to 3.00 m, except for the approaches to major bridges.

19. Cross Drainage (CD) Structures: There are 1 major bridge, 5 minor bridges, and 44 culverts along the entire stretch of the sub-project road.

20. Terrain and Landuse: The overall terrain is wholly in flat terrain with gradual rise in ground elevations from south to north. Road elevations vary from ground level to typically 1.5 metres. It passes through mostly rural areas. Land use on the project corridor constitutes 45% of urban to semi-urban type with residential and commercial uses while the remaining 55% is under agricultural use. The overall terrain is predominantly flat throughout the stretch. Important settlements along the project road are Siwan, Surapur, Chhapiya, Gopalpur, Sahuli, Nawada, Hasanpura, Jalalpur, Simri, Rajjanpura, Madhawapur, Rampur, Bhagwanpur Ghurghar, Chandpur and Siswan.

21. Road Intersections: There are 12 intersections/junctions, and major junctions include the starting point in Siwan with NH-85 which have been designed as at-grade junction.

22. Level Crossing: Only one level crossing is along the sub-project road near Siwan.

2. Category of the Project

23. The sub-project has been evaluated using ADB rapid environmental assessment screening checklist (Appendix 1) for Roads and Highways. The sub-project section does not passes through or located near any wildlife sanctuary, national park, reserved forest, mangrove, estuarine, protected area buffer zone, or any other similar environmental sensitive or protected areas. It traverses agricultural land and some congested urban areas. The anticipated environmental impacts are minimal and most are related with the construction phase. The project has been classified as Category “B” in accordance with ADB‟s Safeguard Policy Statement 2009.

3. Need for the Sub-Project

24. The project road Siwan to Siswan (SH-89) constitutes a very important connection between NH-85 at Aradia Chowk and Tejpur-Majhi-Siswan-Barauli MDR serving as a shorter route for vehicles travelling from NH-85 to Tejpur-Majhi-Siswan-Barauli MDR.

B. Project Components

25. Traffic Scenario: Traffic surveys were carried out at two locations; km 3.00 and at km 27.00. About 60% of total traffic at km 3 is slow moving vehicles and 65% at km 27. Similarly, 25% of total traffic on project road is two wheelers indicating trips on the subproject road are for short distance. The annual average daily traffic (AADT) on the project road as reported below.

Present Traffic Volume at Selected Locations

S.No Location Chainage AADT in PCU

1 Surapur 3+000 5,419

2 Chainpur 27+000 2,321

26. The origin destination survey conducted at km 12.5 and km 81 establishes that local traffic is predominant. Total junction peak hour flow of 5 junctions where intersection turning movement survey was conducted varies from 201 to 2,323 PCU. The speed and delay study conducted along the project gives an average running speed of 35 km/h for section 0 – 22 km; 31.7kmph between 22-50km, and 16.36 for the last section. Low running speed in the last section is attributed to the poor road condition.

27. Projected Traffic: Traffic forecast was carried out considering socio-economic variables such as population, vehicle registrations, and net state domestic product. An optimistic, most likely and a pessimistic scenarios of growth have been estimated for the indicators and the traffic growth rates were established. The following Tables present the projected traffic for both the locations.

C. Key Rehabilitation/Improvement Activities

28. Key activities for sub-project road improvement involves:

widening/strengthening of the road up to 2-lane carriageway configuration with paved shoulders on either side,

improving road geometry,

laying of embankment,

rehabilitation and construction of new bridges and other cross drainage structures,

construction of side drains,

Junctions/intersections improvement, and

provision of underpasses, and way side amenities.

29. Proposed Right of Way: Varying ROW is adopted, from 25 m in built-up areas to a maximum of 30 meters in open areas. In sections with high banks, deep cuts and at intersections, wider land width is required. Proposed formation width is 12m.

30. Road Configuration: It is proposed to convert the present single lane state highway with 2-lane consisting of 7m wide carriageway and 1.5 m wide paved shoulders on both sides. For the structures, new 2 Lane standard configuration with or without footpaths have been proposed for all six locations. Typical cross-section for standard-2 lane road is given in the succeeding Figure.

11

Figure 3-1:Typical cross section of standard 2-lane

31. Geometric Design, Ruling and Design Speed: Geometric design standards are based on the IRC 73-1980 for „plain / rolling‟ terrain as applicable to State Highways. The following other parameters have been used:

Design speed 80 km/h against 100km/h as per IRC

Minimum design speed 40 km/h against 80 km/h as per IRC

The DPR study adopted a reduced ruling and minimum design speeds considering the adverse social impact and economic benefits of utilizing existing road assets. However, alignment can be designed at 100 Km/h wherever possible.

32. Geometric Improvements: The geometry of the existing road is generally satisfactory except at few locations where minor geometric improvement is considered appropriate.

33. Realignment/Bypasses: Two bypasses are recommended with a total length of 3.750 kilometers. The first is between kilometer chainage 0.00 – 2.750 near Siwan to avoid crowded market area and difficulty in improving several existing substandard curves in this section. Further, this section passes through one railway level crossing and construction of ROB at this location is not recommended in the DPR due to low number of gate closures. The same railway line also crosses NH85 about 400m from the project start junction at Km 0+00. The star point of the road section was shifted to avoid construction of separate ROB for NH.

34. Another important realignment is proposed from Km 5+800 to 6+800 near Chatta to avoid heavy built-up area, religious structures, and narrow ROWs. Open land is available on the left side of the project road and realignment of this section on this direction is proposed to avoid the dangerous S-curve.

35. Embankment: Some part of the road is in flood prone area. Overtopping was reported in sections close to Daha River. These stretches are exposed to erosion from floods. Embankment of road in these stretches especially near km 25.850 will be protected by pitching. The final road surface also needs raising at this location with installation of additional culverts are proposed to facilitate cross draining. In order to have more stability to the approach embankments of minor bridges, against erosive

12

attack, as this is a flood prone area, 45 degree splayed wing walls are recommended with rigid aprons, cut-off walls and launching flexible aprons in accordance with practice. Retaining walls will be provided at all required locations for a length of 245m.

36. Bridges and other Cross Drainage Structures: A total of 1 major and 7 minor bridges will be improved under the Project. All 44 culverts will be replaced and an additional 51 culverts will be added to facilitate cross drainage.

37. Roadside Drainage: No proper drainage exists in the entire stretch. Suitable drainage provision shall be designed based on detailed hydrological design from contours, characteristics of catchment, location of outfall points, rain fall intensity and need to furnish the open drainage design and schedule. Provision of 3,150m of drain has been made on both sides. In rural stretches, provisions of longitudinal side drains intercepted by mitre drain are proposed to be constructed to serve as outlet channel.

38. Junctions/intersections Improvement: A total of 5 junctions will be improved in compliance with IRC standards. Layouts will feature separate left and right turning lanes protected by raised (curbed) channelizing islands. The required taper and parallel lane acceleration and deceleration dimensions will conform to the above standards. List of Junctions to be improved are given below.

2 Daranda Andar road 16.995 X Junction

3 Chhapra Road 26.800 T Junction

4 End of the project road 33.221 T Junction Source: Interim Report, PPTA

39. Service Roads and Underpasses: Presently, no provision of service roads has been made. To accommodate the slow moving traffic in the built-up areas and to improve overall safety and level of service in the main carriageway, pedestrian walkways/cycle paths are recommended with following components.

Construction of pedestrian walkway/cycle path (1.0+ 2.0 m wide) on built up sections on both side of the road.

Concrete kerb with CC M20 to separate fast and slow moving traffic to channelize the traffic

Pavement for pedestrian walkways/cycle paths shall be 250mm Granular gravel base course with PCC

40. Utility Shifting: There are a number of amenities and utility services along the project corridor including high and low tension electrical lines, water and telephone lines, and optical fiber cables. All such utilities shall be safely shifted/relocated in coordination with the concerned departments.

41. Plantation/Landscaping: The project highway will have plantation of trees along the highway on both sides based on IRC: SP: 21. Plantation scheme will be reviewed so that it does not affect the road safety including visibility. A range of 10-15 m center-to-center distance is recommended for spacing of trees. Setback distance of trees in different situations shall be as per IRC: SP: 21 and IRC: 66. The distance between the kerb, if any, and the nearest edge of tree trunk shall be at least 2 m.

42. Road Safety Provisions: Adequate road safety features like crash barriers, markings, and signages will be provided in accordance with the requirements of IRC/MOSRTH. The executing agency has developed a road safety unit to institutionalize

13

road safety audits, to ensure that safety elements of IRC standards are incorporated in design and during construction.

43. Material Sourcing: A total of 383,006.82 cu.m. of earth will be borrowed for the proposed road upgrading. Earth can be borrowed from nearby areas along the project road. The soil from the borrow areas are in compliance to MoRTH recommendations for the construction of embankment and earthen shoulder. Identified borrow areas are given below.

44. The coarse aggregates for the construction work will come from the Pakur, Karnwadiha, and Shiekpura quarries. Stone metal and morrum can also be obtained from Shekpura area which is situated at a distance of 273 Km from Siwan. The source of coarse sand is located near Doriganj which is about 80 Km from Siwan. Bitumen and emulsion are obtained from Barauni and Uluberia which are 270 Km and 590 Km, respectively from the sub-project road.

45. NTPC‟s thermal power plant at Kanti is located about 100 km from the Siwan. Fly ash shall be used mandatorily in road construction as per fly ash notification. Since, there is shortage of fly ash due to ongoing construction works of NH-28 and other highways nearby; use of fly ash has not been proposed.

D. Project Implementation Schedule and Cost

46. The project is in the detailed design stage. The Project will be implemented over 3 years, inclusive of procurement, preconstruction activities in 2012. It is expected to be completed by 2015. The estimated cost of the project excluding resettlement and rehabilitation and EMP implementation is 167.96 crores rupees.

4. DESCRIPTION OF THE ENVIRONMENT

47. A description of the existing environment, including its physical and ecological resources, economic development of the region, and issues relating to quality of life are presented in this section.

A. Physical Environment

1. Meteorology and Climate

48. The state has a tropical monsoon climate with three distinct seasons; winter, summer, and rainy. The state can be divided into three climate zones based on physiographic set-up: (a) Sub-Himalayan zone, (b) Ganga plains zone, and (c) parts of Chotanagpur plateau zones of South Bihar.

49. The project district lies in the Ganga plains zone. The district observes hot and damp easterly winds from March to May with afternoon storms accompanied by rain. The summer season experiences “Loo” during May and June having temperature above 400C. Since the district is in the transitional zone, monsoon rain starts late and persists until September. This period provides maximum rain to the area. July and August are oppressive months due to heat and high humidity. The winter season is normally pleasant with low temperature and light rains intensify the cold. The annual rainfall of Siwan for last 3 years is presented in Table below.

2. Natural Hazards

50. Flood: Out of 36 districts in Bihar, 28 districts are susceptible to flood. This constitutes nearly 17% of the total flood affected area in the country affecting 22% of the country‟s total population. The north Bihar plains are drained by a number of rivers viz. Kosi, Gandak, Burhi Gandak, Bagmati, Kamla Balan, Mahananda and Adhwara Group. They originate in Nepal, carry high discharge and very high sediment load and drop it down in the plains of Bihar. About 65% of catchments area of these rivers falls in Nepal/Tibet. The plains of north Bihar have recorded the highest number of floods during the last 30years. In the years 1978, 1987, 1998, 2004 and 2007 Bihar witnessed high magnitudes of flood. Among all, 2004 flood was most severe when the flood level surpassed all time high flood level. At many places, the embankments of north Bihar were breached, resulting in flood inundation in a vast area of North Bihar.

51. In 2008, there was an unprecedented flood due to breach of Eastern Kosi Afflux Embankment with catastrophic results in Sunsari and Saptari districts of Nepal and Supaul, Madhepura, Araria, Saharsa, Katihar and purnea districts of Bihar. The River Kosi entirely changed its course from earlier one which was again tamed to its original course by Water Resources Department.

15

52. Drought: In Bihar, the districts usually affected by drought are Kaimur, Rohtas, Aurangabad, Jehanabad, Gaya, Nawada, Jamui, and Banka. Most part of the project area is not subjected to drought.

53. Seismicity: Bihar being close to seismically active Himalayas, is prone to seismic hazards. According to Seismic Zonal Map of India prepared by Bureau of Indian Standard, Bihar lies partially in Zones IV and V. The project district is located in the Zone IV denoting higher damage risk. A multi-hazard zone map, shown in the succeeding Table, prepared by United Nation Development Program (UNDP) indicates that both the project districts fall under moderate zone with respect to earthquakes, flood and cyclones.

Figure 4-1: Multi Hazard Zone Map of Bihar

3. Air and Noise Quality

54. In absence of secondary data on ambient air quality and noise levels at the project area, onsite monitoring was conducted at few select locations. Most of the project area lies in vast open agricultural land largely free from air pollution and noise generating sources other than traffic and few brick kilns. These brick-kilns are equipped with smokestack, located in open area, and operate only for few months. Ambient air monitoring was carried out at two locations, at 100 meter away from highways in urban and rural areas.

Air Quality

55. The ambient air quality levels with respect to suspended particulate matter (SPM), respirable particulate matter (RSPM), sulfur oxides (SOx), and nitrogen oxides

16

(NOx) range from 345 to 420 µg/m3, 145-162 µg/m3, 213.5-14.5 µg/m3,8.5 to 7.2 µg/m3 and 13.5-14.5 µg/m3 , respectively in the project area. These ambient air quality levels conform to the prescribed National Ambient Air Quality Standards (NAAQS) appended as Appendix 4.1 except for PM 10 at both the sampling site due to heavy traffic, unpaved shoulders and inadequate road capacity.

4. Landforms/Physiography and Topography

Based on broad geomorphic parameters, Bihar may be divided into three geomorphic domains. They are: (i) uplifted block of hilly southern highlands (ii) Ganga foredeep of the North Bihar Plains bounded by the rising Himalaya in the north and the Ganga R. in the south and (ii) The transition zone between the southern highlands the Great Ganga Plains, constituting the central Bihar Plains. The subproject area lies in Central Bihar Plains. This geomorphic/physiographic unit has been further categorised into three land systems e.g. (i) Alluvial upland (ii) Older Flood Plain, and (iii) Present Flood Plains.

57. The project district lies in an alluvial landscape shaped by the Himalayan and Sub-Himalayan Rivers Gandaki and Ghaghara. The district is also navigated by few small rivers like Jharahi, Daha, Gandaki, Dhamati or Dhamahi, Siahi, Nikari, and Sona. Among these, Ghaghara is the perennial river, which flows alongside the district's boundary. The project road connects the centre to southern end of Siwan district and is situated at about 120 meters above MSL.

17

5. Geology

58. The State of Bihar exhibits diverse geological formations ranging in age from

Archean to Holocene. Geologically, Bihar represents the extreme northern front of Indian sub-continent. These include: (i) belt of Himalayan foothills in the northern fringe (ii) vast Ganga Plains, (iii) Vindhyan (Kaimur) Plateau (iv) sporadic and small Gondwana basin outliers in Banka district, (v) Satpura Range extending into large part of the area north of Chotanagpur Plateau, (vi) parts of Bihar Mica belt in Nawada, Jamui and Banka districts and (vii) Granite Gneissic complex of Chotanagpur plateau.

59. The project district is situated in the western part of North Bihar and Ganga basin. Lithostratigraphically, the project area is part of Magadh Formation characterized by silt, clay, and sand of quaternary period transgressing over the alluvial upland and spreading along the valley sides of river drainage systems.

Figure 4-2: Geological Map of Bihar

6. Soil

60. There are three major types of soils in Bihar, namely: (i) Piedmont Swamp Soil found in north-western part of west Champaran district, (ii) Terai Soil found in northern part of the state along the border of Nepal, and (iii) Gangetic Alluvium is spread along the plain of Bihar. The district of Siwan falls between Bhanger plain of Uttar Pradesh and Khader plain of West Bengal. „Bhanger‟ or Banger is an older alluvium containing heavier soil with greater clay proportion, while Khader is the newer alluvial deposit by river floods, both types of soils are found in the district, but Khader is limited to the vicinity of the rivers where it is periodically renewed by fresh deposits, especially in “Diara” areas. Khader is locally termed as 'Domat' and „Bhanger‟ as 'Balsundari'.

9. Surface water

a. River System and Water bodies of the Project Area

65. The major river in the project area is Daha. It lies in the western side of the subproject road, finally crossed it after Chainpur market at 29.8km Chainage. The Daha River is perennial in nature. It originates from Nepal with its outfall at River Ganga. List of water bodies along the corridor is given below.

Table 4-8: List of Water Bodies Along/across Project Corridor

b. Siltation and other Hydrological Attributes of Rivers of the project area

66. The Daha River is instrumental for water stagnation in low-lying area due to backwater flow/over flow from the river. The water carrying capacities of the River have reduced over time due to siltation resulting in floods in the basin. The flood affected sections of the project road is from Hassanpura area up to Ghurghut including the Chainpur main market area.

c. Surface Water Quality

67. Surface water sample taken from the Daha River have been compared with the standards prescribed by Central Pollution Control Board (CPCB) for Irrigation- Class D and propagation of wild life and fisheries -Class-E (Appendix 4). The results of the samples conforms their suitability for both these purposes. Results of the surface water quality in the project area have been summarized below.

C. Ecological Resources

1. Terrestrial Ecology

a. Forests

68. Forest Areas: The state of Bihar has only 6.9% of forest cover to its total geographic area. Legally this area has been classified into "Reserved Forest, Protected Forests, and Unclassified Forest" and their areas are 693 sq. km (0.75%), 5779 sq. km (6.14%) and 1 sq. km (0%) respectively. Per capita forest area in the state is 0.01 ha against the national average of 0.07 ha. The latest estimates of Forest Survey of India (FSI), published in the State of Forest Report (SFR) 2003, suggest that the total forest cover of Bihar is 5,558 sq. km., which is 5.9% of the land area.

69. Forest Types and its Spatial Extent: There are three forest types in the state dry and wet deciduous, and Tarai. Dry deciduous found in northeastern of Kishanganj district and particularly in the water logged area with annual rainfall more than 120 cm. Density of vegetation is very high. The major vegetation type are Sal, Assam, Semal, Ghaura, Caham, Kend, Mango ,and Jamun. The wet deciduous forest is found in hills of Kanpur and Chotanagpur plateau and in few parts of Raxual, Purnia and Araria districts where the annual rainfall is less than 120 cm. They are not dense forest and categorized as open forest. The major vegetation type is Sal, Bamboo, Khair, Pal, Shisham, Mahua and Kend.

3. Economic Development

74. The economy of Bihar is largely service oriented, but it also has a significant agricultural base. There is also a small industrial sector. As of 2008, agriculture accounts for 35%, industry 9% and service 55% of the economy of the state. Bihar has the lowest GDP per capita in India, although there are pockets of higher than the average per capita income. Between 1999 and 2008, GDP grew by 5.1% a year, which was below the Indian average of 7.3%. More recently, Bihar's state GDP recorded a growth of 18% between 2006-2007, and stood at 942510 Crores Rupees ($21 billion nominal GDP).

24

This makes Bihar the fastest growing major state. In actual terms, Bihar state GDP is ranked 14th out of 28 states in India. Various facets of socio-economic environment of the state and the project district are described in following paragraphs.

a. Industries

75. Contribution of industrial sector to the state‟s economy is insignificant. This is mainly due to poor investment climate. Key industries in the state include food processing/beverages fibres/textile, jute, leather, mines and minerals, tobacco, dairy, tea, petroleum products, cement etc. Unregistered units dominate the overall industrial sector, accounting for more than half of its total income. There are 259 large and medium industries involved in food, beverages, tobacco, and petroleum products accounting for more than 85% of the total industrial income. Total value of output of agro-based industries is less than 1% of the national output, despite the fact that Bihar produces about 10% of India‟s total output of common fruits and vegetables.

76. The project district is mainly characterized by agro-based small-scale cottage industries; light engineering, food, and food processing are the major industrial activities. Major industries located in the area are mainly sugar factories, thermal power station, wagon factory, and pharmaceutical. Small-scale industries include saw mill, rice mill, suji factory, beverages, cold storage, plywood etc. Project area is largely devoid of any major industries.

77. Contribution of industrial sector to the state‟s economy is insignificant, mainly due to poor investment climate.

Total value of output of agro-based industries is less than 1% of the national output, despite the fact that Bihar produces about 10% of India‟s total output of common fruits and vegetables. Project area is largely devoid of industries.

4. Infrastructure Facilities

a. Water Supply

78. Bihar ranks among top states in accessibility and availability of safe drinking water supply. Nearly 90% of the total population gets safe drinking water. Projects districts are also richly endowed by groundwater and surface water resources. Groundwater is principally used for drinking and domestic purposes in the project influence area.

b. Transportation

79. Roads: The State is serviced by 2318 kms. of national highways, 4192 kms. of state highways, 12,579 kms. of district roads and over 69000 kms. of other roads. Only

25

50% of the other roads are surfaced. The total road length per 100 sq km is 77 km and the road density in is only 901 km per million populations. About half of villages lack all-weather road connectivity.

80. Railways: Bihar‟s railway network is fairly well developed, with the railway route density (route kilometers per 1000 sq km) in the state being 30.15, compared to 19.09 for All-India. Total rail length in the state is 5,400 km.

81. Waterways: Bihar is traversed by several rivers. Some of the major rivers are the Ganges, Ghaghra, Gandak, Kosi, Damodar, Sone and Swarnarekha. Total length of rivers in Bihar is 4,414 kmsnavigable length of rivers is 1,325 kms. Farakka to Buxar in the river Ganges has been declared as National Water Ways No.1. It is presently operative from Haldia to Patna. This provides access to Calcutta Seaport (417Kms) and Haldia (517 Kms). 82. Civil Aviation: Patna, Gaya, Muzaffarpur, Raxoul and Jogbani have domestic airports Patna International Airport is directly connected with Kathmandu (Nepal), and important destinations of the country. 39 district Head Quarters have air strips/aerodromes. The state government has plans to set up Air Cargo Complex in Patna that will be promoted by Bihar Industrial Area Development Authority and Airport Authority of India.

c. Power Sources and Availability

83. After bifurcation of Bihar with a newly carved state Jharkhand, 70% of the generation capacity of erstwhile Bihar has gone to the jurisdiction of the state of Jharkhand, but 70% of the load is left with present Bihar. Bihar‟s power generating capacities stand at 540 MW of capacity in thermal plants in Barauni (320 MW) and Muzaffarpur (220MW) with a limited amount of power (25 MW) available from the hydel power sources. With 41% of its villages electrified, power is being viewed as a focus area with new projects in the pipeline involving a total estimated cost of US$ 4.4 billion with a targeted capacity of 4820 MW.

d. Agriculture

84. About 85% of state's population are dependent on agriculture and allied. The major crops of Bihar are paddy, wheat, lentils. Bihar is also the leading producer of cash crops like tobacco, chillies, turmeric, oilseeds, sugar, and jute. It produces some of the finest varieties of mangoes, litchis, guavas, sapotas, citrus, pineapples, and bananas. Bihar is the largest honey producer of India. The state is distinguished as the "Rice Bowl" of East India. It has 6%, 6%, 11% and 9% share of rice, wheat, maize, and jute respectively, produced in India. Bihar is one of the largest vegetables producers.

85. The sub-roject districts produces several of major crops like rice, wheat, maize, and barley; pulses like gram, masoor, arhar, and khesari peas; and cash crops like sugarcane, potato, tobacco, jute, and chillis.

26

e. Mineral Resources

86. Unbifurcated Bihar had vast mineral reserves. About 90% of the important minerals

are now left with Jharkhand after separation. Still some more important minerals are located in the state contributing in states revenue though insignificant. Minerals found in the states are Limestone, Pyrite, Magnetite, Steatite, Mica, China clay, Soapstone, Slate, Felspar, Galena, Sandstone, Saltpetre, etc. None of the mineral deposits is located in the project districts.

5. Social and Cultural Resources

a. Population and Communities

87. The total population of Bihar is 82.8 million, third most populous state in the country. The project district contributes nearly 4 % of the state population. The decennial growth rate of population of Bihar during 1991-01 was 28.43%. The sex ratio in the State i.e. number of females per 1,000 males marginally increased from 971 in 1991 to 972 in 2001 as compared to the all India average, which increased from 927 to 933 during the same period. The density of population, which was 685 persons per sq km in 1991, increased to 880 per sq km in 2001. The urban population of 13.38% in 1991 increased to 14.47 % in 2001. According to the census 2001, the state of Bihar and the project district have following facts on Population

8. Occupational Status and Migration

90. Of the total population of 82.88 million people, roughly 28 million people (34% of the population) comprise the workforce in the state. Though Bihar is the third largest populated state in India, it accounts for about 7% of the total organized sector employment in the public sector. In the private sector, the share of Bihar is still lower at about 3%. There has been a large increase of subsidiary status workers in the state, pointing to the presence of a high degree of disguised unemployment as well as temporary/casual labour. Maximum percentage of the workers is in the agriculture sector as a cultivator or agricultural labourers. More than 80% of the rural population is engaged in the agriculture sector. The National Sample Survey Organisation (NSSO) data shows that wage employment in the agricultural labour accounted for nearly 40% of the rural work force in Bihar in 1999-00. Agriculture labour and cultivation together account for around 80% of occupations in 1999-00. In urban areas, more than 40% households are self-employed. Around 30% have regular employment in 1999-00. Percentage of main workers to total population and distribution of working populations under various categories of subproject distritcs and types of workers are provided in the Table below.

91. Migration is crucial survival strategy for the rural poor in Bihar. The National Survey Sample reported that Bihar has the highest rate of gross interstate migration in the India. Most of the migrants are male (95%) and that of poor section.

9. Current use of lands and resources for traditional purposes by Indigenous Peoples

92. Tribal population in the project area is insignificant. Those living, are in the mainstream of the society and do not depend on forest and its resources for any purpose. Moreover, there is no forest resource in the project area.

a. Structures or sites of historical, archaeological, paleontological, or architectural significance

93. There is no such site of significance either impacted or in the close vicinity of the project area.

b. Areas of Eco-Sensitivity/Protected Area/Restricted Area legislative and others

94. No such eco-sensitivity areas, protected area, restricted area and legislative and others were found in the sub project area.

29

5. ANTICIPATED ENVIRONMENTAL IMPACTS AND ITS MITIGATION MEASURES

95. Environmental impacts have been assessed considering present environmental setting of the project area, nature, and extent of the proposed activities. Suitable approach and methodology was adopted to ascertain likely impacts both during design and construction and operation stage. Valued Environmental Components were identified during initial site visit followed by its detailed investigation during later stage of the study.

A. Impacts and Mitigation Measures on Physical Environment

1. Climate

a. Design and Construction Phase

96. Cutting of approximately 972 trees will have minor to negligible impact on microclimate of the region. The compensatory plantation, involving 2,916 trees, will improve the micro climate of the region.

Mitigation Measures

97. All efforts shall be made by the contractor to minimize cutting of the trees up to final stage of project implementation. The project envisaged plantation of approximately 2,916 trees as a compensatory plantation as in compliance to prevailing guidelines of State‟s Forest Department on 1:3 basis. The contractor will be responsible to coordinate with the authorities about compensatory plantation that will include meetings, actions and discussions with concerned authorities. Besides, additional plantation is recommended near sensitive locations, riverbanks and wherever additional land is available with PWD.

Operation Stage

98. The sub-project road is mostly located in open agricultural land which will provide adequate dispersion of gaseous emission from vehicle. Further, extensive plantation will ameliorate/enhance the micro climate. No adverse climatic changes/impacts are anticipated during operation stage other than CO2 emission from vehicles.

2. Natural Hazard

99. Some parts of the project alignment have evidences of overtopping during monsoon period, requiring raised formation level of the proposed road. This may aggravate the flood situation if adequate engineering solutions are not included in the design considering the local/regional hydrology of the area.

100. The project area is located in seismic zone IV which is high damage risk zone. This may cause failure of civil structures in the event of earthquake if design consideration related to seismicity is not taken into consideration.

Mitigation Measures

101. Provisions of adequate cross drainage structures, like culverts/balancing culverts/causeways and roadside drainage shall be made to avoid flooding/water logging. The height of embankment shall be adequately raised at least 1 meter above highest flood level. The design discharge shall be evaluated for flood of 50-year return period for calculation of waterway and design of foundations.

30

102. Earthquakes may cause failure of civil structures if inadequately considered in the design stage. Related to seismicity is not adequately taken into consideration. Relevant IS codes shall be adopted while designing the civil structures to sustain the earthquake of highest magnitude in Seismic zone IV.

103. Following IRC guidelines have been followed in the design for construction and protection of embankment in the flood affected stretches.

IRC: 34-1970: Recommendations for road construction in waterlogged areas

IRC: 75-1979: Guidelines for Design of High Embankments

IRC: 56-1974: Recommended Practice for Treatment of Embankment Slopes for Erosion control

104. Key provisions are

Provisions of adequate cross drainage structures, like culverts/balancing culverts/causeways and roadside. The height of embankment adequately raised above highest flood level with 1 m free board. The design discharge has been evaluated for flood of 50-year return period for calculation of waterway and design of foundations.

Retaining walls, Toe walls near water bodies for protection of embankment.

Turfing with sods along slope of embankment to prevent erosion of embankment material.

Floor aprons on upstream and downstream of culverts and minor bridges

3. Air Quality

Design and Construction Phase

105. The potential sources of air emission during the construction phase of the project are: (i) dust from earth works during site preparation; (ii) emissions from the operation of construction equipment and machines; (iii) fugitive emissions from vehicles plying unpaved roads; (iv) fugitive emissions during the transport of construction materials; (v) air emissions other than dust arise from combustion of hydrocarbons particularly from the hot mix plants, and (vi) localised increased traffic congestion in construction areas.

Most of the emissions will be in the form of coarse particulate matter which will settle down in close vicinity of construction site. Installation of crusher unit will also lead to air pollution. Hot mix plant will generate carbon monoxide (CO), un-burnt hydrocarbon, sulphur dioxide, particulate matters, and nitrogen oxides (NOx) emissions. This may affect the air quality of nearby areas especially due to emission discharge from low height stack. However, this will be a temporary phase and hence, no significant adverse impact is envisaged.

Mitigation Measures

106. The following mitigation measures to minimize impacts on air quality:

Vehicles delivering loose and fine materials like sand and aggregates shall be covered.

31

Loading and unloading of construction materials in covered area or provisions of water fogging around these locations.

Storage areas should be located downwind of the habitation area.

Water shall be sprayed on earthworks periodically

Regular maintenance of machinery and equipment. Vehicular pollution check shall be made mandatory.

Mixing plants and asphalt (hot mix) plants shall be located at least 1 km downwind of the human settlements. The asphalt plants, crushers and the batching plants shall be sited at least 500m in the downwind direction from the nearest settlement and after securing a No-Objection Certificate (NOC) from the SPCB. Hot mix plant shall be fitted with stack of adequate height as may be prescribed by SPCB to ensure enough dispersion of exit gases.

Bitumen emulsion and bitumen heaters should be used to extent feasible.

Only crushers licensed by PCB shall be used.LPG should be used as fuel source in construction camps instead of wood. Tree cutting shall be restricted.

Regular Water sprinkling of unpaved haulage roads.

Mask and other PPE shall be provided to the construction workers

Diesel Generating (DG) sets shall be fitted with adequate height as per

regulations (Height of stack = height of the building + 0.2 KVA.

Low sulphur diesel shall be used in DG sets as well as machineries.

Air quality monitoring should be carried out during construction phase. If monitored parameters are above the prescribed limit, suitable control measures must be taken.

Operation Phase

107. Vehicular emission will be the principal source of pollution during operation stage. The sub-project road is mostly located in open agricultural land which will provide adequate dispersion dynamics of gaseous pollutants. Moreover, majority of the traffic on the sub-project will be diverted traffic from the existing highways.

Mitigation Measures

108. Plantation is one of the preferred solutions to check air pollution. Plants serve as a sink for pollutants, and reduce the dispersion of dust. Tree plantation along roadsides and other places shall include pollution absorbent species.

109. Road signs shall be provided reminding the motorist to properly maintain their vehicles to economize on fuel consumption and protect the environment.

110. Driver education will be promoted on the benefits of driving practices that can reduce fuel consumption and promote safety when driving within the speed limits and avoiding sudden acceleration.

4. Noise

Design and Construction Phase

111. Ambient noise level may increase temporarily in the close vicinity of various construction activities, maintenance workshops, vehicles and earthmoving equipment. These construction activities are expected to produce noise levels in the range of 80 –

32

95 dB(A) at a distance of about 5 m from the source. Although this level of noise is higher than the permissible limit for ambient noise level for residential/commercial levels, these are expected to be short term episodes rather than sustained exceedance. Impact due to noise during construction activities will be minimal to inhabitants since most of the built-up areas are either bypassed or located at safer distance from the road. However, there are few noise sensitive locations especially schools close to the alignment sa shown below.

Table 5-1 List of Some Noise- Sensitive Locations along the Alignment

S. No Structures Chainage Remarks

1 School (RHS) (14.3) Partially impacted

2 School (LHS) (19.4) Partially Impacted

3 School (LHS) (21.9) Partially impacted

4 School (LHS) (26.6) Partially impacted

5 School(LHS) (28) Impacted

6 School (RHS) (30.8) Partially Impacted

7 School(RHS) (33.2 ) Impacted Likely to be relocated

Mitigation Measures

112. The following mitigation measures will be implemented to minimize or avoid impacts due to elevated noise level:

All equipment shall be timely serviced and properly maintained to minimize its operational noise. Noise level will be one of the considerations in equipment selection which will favour lower sound power levels

Stationary noise making equipments shall be placed along un-inhabited stretches.

On areas near schools, several approaches to reduce noise will be employed by the Contractor to ensure compliance with noise standards. These approaches include the timing of noisy construction activities during night time and weekends when there are minimal activities near by the sensitive receptor, concurrent noisy operations may be separated to reduce the total noise generated, and if possible re-route traffic during construction to avoid the accumulation of noise beyond standards.

If the above mentioned schemes prove to be inadequate, the provision of temporary noise barrier shall be made near identified sensitive locations re near the noise source during construction. If temporary noise barriers are not feasible then timing for construction activities shall be regulated.

Protection devices (ear plugs or ear muffs) shall be provided to the workers operating in the vicinity of high noise generating machines.

Construction equipment and machinery shall be fitted with silencers and maintained properly.

Noise measurements should be carried out to ensure the effectiveness of mitigation measures.

Develop a mechanism to record and respond to complaints on noise

33

Operaton Phase

113. During the operational phase, movement of traffic will be the prime source of noise. Traffic congestion and pedestrian interferences increase the use of horns. This may result in increase noise levels at at nearby schools and religious place.

Mitigation Measures

Effective traffic management and good riding conditions shall be maintained to reduce the noise level throughout the stretch and speed limitation and honking restrictions may be enforced near sensitive locations.

The effectiveness of the multilayered plantation should be monitored and if need be, solid noise barrier shall be placed.

Create awareness amongst the residents about likely noise levels from road operation at different distances, the safe ambient noise limits and easy to implement noise reduction measures while constructing a building close to the road.

5. Impact on Land and Soil

a. Loss of Productive Soil and Change in Land use

Design and Construction Phase

114. The sub-project road improvement will require conversion of some agricultural lands. The exact requirement of land is being assessed during the preparation of this report. No sensitive area like forest or any other sensitive land, including their buffer zones will be involved.. Minor impact on agricultural yield is anticipated due to the sub-project but the benefits to the individual farmers accrued against reduced yield may get compensated through enhanced accessibility to the commercial market.

115. In addition to above, land may be required for access road and construction camp for the duration of construction period. This will also result in loss of soil productivity.

Mitigation Measures

116. The top soil from the productive land shall be preserved and reused for plantation purposes. It shall also be used as top cover of embankment slope for growing vegetation to protect soil erosion.

117. It shall be ensured that the land taken on lease for access road and construction camp is restored back to its original land use before handing it over back to land owner.

Operation Phase

118. Improved access can lead to conversion of agriculture land for residential and commercial purposes close to road resulting to further loss of productive land and agricultural produce.

Mitigation Measures

34

119. The EA may explore the feasibility of restricting about 50 m-100 m area either side of the road as no development zone on the line restriction are imposed for National Highways in India.

i. Soil Erosion

120. Soil erosion is mainly anticipated near bridge locations, along steep &and uncompacted embankment slope, earth stock piles, and wherever vegetation is cleared. Soil erosion may have cumulative effect like siltation, embankment damage, and drainage problem. The intensity of soil erosion at different locations will be influenced by the lithology, topography, soil type and climatic condition (mainly rainfall) and drainage pattern.

Mitigation Measures

Bank protection measures shall be taken at erosion prone areas. The protection measures may include use of geo-textiles matting.

Provision of side drain to guide the water to natural outfalls.

Stone pitching wherever necessary.

When soil is spread on slopes for permanent disposal, it shall be buttressed at the toe by retaining walls.

Side slopes of the embankment shall not be steeper than 2H:1V. Turfing of embankment slopes shall be done along the stretch.

Though terrain is flat all through the stretch. However, all steep cuts shall be flattened and benched. Retaining wall on both sides shall be provided. Shrubs shall be planted in loose soil area.

In rural stretches, longitudinal side drains shall be intercepted by „mitre‟ drains serving as outlet channels to reduce the erosion.

IRC: 56 -1974 recommended practice for treatment of embankment slopes for erosion control shall be taken into consideration.

Soil erosion shall be visually checked on slopes and high embankment areas. In case soil erosion is found, suitable measures shall be taken to control the soil erosion further including bio-turfing.

Operation Phase

121. Soil of steep slopes of embankment and near bridge approaches may erode the embankment formation due to unexpected rainfall. Soil erosion condition may arise if borrow area are not stabilized/restored properly. Regular monitoring for effectiveness of soil erosion measures like turfing and stone pitching shall form part of the environmental monitoring during project operation. Suitable strengthening measures shall be taken to prevent reoccurrence of soil erosion at existing erosion prone locations and prevent erosion at newer locations.

b. Borrow Areas and Quarries

122. The sub-project area is located in a flat terrain with some depressed sections. All borrow identified by the DPR team is located nearby the subproject road. Local farmers were ready to provide earth from their field up to certain depth on adequate compensation. However, it is recommended that borrowing from agricultural land shall be minimized and borrowing from already low lying areas. Local people suggested that

35

river bed material can be utilized in embankment if found suitable to help in improving river carrying capacity and reduce need of sourcing borrow earth from agriculture fields. The dredging and use of dredged material if involved may have its impact in terms of localised sedimentation level increase and dispersion of pollutants present in the dredged material in the river water.

123. Borrow areas if left un-rehabilitated may pose risk to people, particularly children and animals of accidentally falling into it as well as become potential breeding ground for mosquitoes and vector born disease

124. Illegal quarrying may lead to unstable soil condition; destroy the landscape of the terrain, air and noise pollution. Opening of new quarries is not envisaged due to the proposed project. Quarry material will be sourced from existing nearby quarries.

Mitigation Measures

Borrow pits shall be selected from barren land/wasteland to the extent possible. Borrow areas should not be located on cultivable lands except in the situations where land owners desires to level the land. The top soil shall be preserved and depth shall be restricted to the desired level.

Borrow areas should be excavated as per the intended end use by the owner. The Indian Road Congress (IRC):10-1961 guideline should be used for selection of borrow pits and amount that can be borrowed.

The dredged material from the river bank shall be tested for presence of heavy metals and other pollutants before its reuse.

The depths in borrow pits to be regulated so that the sides shall not be steeper than 25%, To the extent possible, borrow areas shall be sited away from habitated areas. Borrow areas shall be levelled with salvaged material or other filling materials which do not pose contamination of soil. Else, it shall be converted into fishpond in consultation with fishery department and land owner/community.

Monitoring of rehabilitation plan of borrow areas in tune with proposed rehabilitation plan has been appended as Appendix 5.1.

c. Compaction and Contamination of Soil

125. Soil in the adjoining productive lands beyond the ROW, haulage roads, and construction camp area may be compacted due to movement of construction vehicles, machineries and equipment, and due to sitting of construction camps and workshops. Approach road either paved or unpaved is available for most the bridge approaches. However, for some bridges approach road has to be constructed.

126. Soil may get contaminated due to inappropriate disposal of liquid waste, (lubricating oil and fuel spills, waste oil and lubricant and vehicle/equipment washing effluent) and solid waste (fuel filters, oily rags) likely to be generated from repair and maintenance of transport vehicles, construction equipment and machinery. Soil may get contaminated due to inappropriate disposal of domestic solid waste and sewage from construction camps.

Mitigation Measures

Fuel and lubricants shall be stored in a paved area with gentle slope to a corner and connected with a chamber to collect any spills of the oils.

36

All efforts shall be made to minimise the waste generation. Unavoidable waste shall be stored at the designated place prior to disposal. To avoid soil contamination at the wash-down and re-fuelling areas, “oil interceptors” shall be provided. Oil and grease spill and oil soaked materials are to be collected and stored in labelled containers (Labelled: WASTE OIL; and hazardous sign be displayed) and sold off to SPCB/ MoEF authorized re-refiners.

To prevent soil compaction in the adjoining productive lands beyond the ROW, the movement of construction vehicles, machinery and equipment shall be restricted to the designated haulage route.

Approach roads shall be designed along the barren and hard soil area to reduce the compaction induced impact on soil.

The productive land shall be reclaimed after construction activity.

Septic tank or mobile toilets fitted with anaerobic treatment facility shall be provided at construction camp.

Domestic solid waste at construction camp shall be segregated into biodegradable and non-biodegradable waste. The non-biodegradable and recyclable waste shall be sold off. Efforts shall be made that bio-degradable waste shall be composted in the mechanised and movable composter3 by the contractor. Non biodegradable and non saleable waste shall be disposed off to authorised land fill site. If land fill site not available then burial of the waste in a secured manner shall be ensured.

Operation Stage

127. No impact on soil is anticipated during operation phase of the project except (i) near low lying areas and near bridge approaches where unexpected rainfall may erode the embankment formation and deterioration of borrow areas if not rehabilitated properly.

Mitigation measures

128. Monitoring of borrow areas rehabilitation is provided in Appendix 5.1.

129. Regular monitoring of side drains and cross drainage structures to check blockade situation.

6. Groundwater

Design and Construction Stage

130. Water will mainly required for compaction of formation and for domestic purpose in the workers camp. Water for construction purpose and domestic water requirement for workers camp will be mainly sourced from groundwater. Groundwater resources are not scarce in the project area. But, the depth to water table in some part is depleting annually. Hence, uncontrolled abstraction can further deteriorate the situation. Contamination of groundwater is not envisaged since all construction camps will have septic tanks or mobile toilets depending on the number of workers in each camp.

Mitigation Measures

131. Permission shall be obtained for abstraction of groundwater.

3 The low costs and small capacity and size composter are available in India which can be used to disposed of bio-

degradable waste effectively.

37

132. The contractor shall make arrangements for water required for construction in such a way that the water availability and supply to nearby communities remain unaffected.

Operation Stage

133. No impact is anticipated on groundwater due to the project during operation phase of the project hence no specific mitigation is proposed.

7. Impact on Surface Water Bodies

Design and Construction Stage

134. Only the River Daha and a canal is being crossed by the project road. Ponds with water for significant part of the year are located safely from proposed right- of way. Surface water bodies are used only for cattle bathing and washing. Less water was observed in the ponds/water bodies likely to be affected during study period.

Mitigation Measure

135. River Daha crossing the project road is likely to be effected during the construction period. Efforts shall be made to increase the water holding capacity of the River and all the ponds by using the bed material as borrow earth4. Additionally, the borrow areas can be converted into ponds with the concurrence of the land owners.

8. Siltation and Surface Water Quality of Rivers and Other Water Bodies

Design and Construction Stage

136. The Daha River is perennial in nature. During the construction period construction debris/other waste along the river must be cleared immediately after construction. The temporary pollution of water bodies from spillage of chemicals and oil at construction sites and waste from construction camps may occur. Soil erosion has direct bearing on siltation. The siltation likely to be caused due to bank erosion has already been addressed above in soil erosion section.

Mitigation Measure

Required mitigation as suggested in soil erosion section shall be taken into consideration.

Bridge construction activity including piling is recommended during non monsoon (mid September to mid June) period.

Silt fencing and/or brush barrier shall be installed for collecting sediments before letting them into the water body. Silt/sediment should be collected and stockpiled for possible reuse as surfacing of slopes where they have to be re-vegetated.

All wastes arising from the construction should be disposed in an environmentally accepted manner so as not to block the flow of water in the channels. The wastes should be collected, stored and transported to the approved disposal sites.

4 Over the period, the depth of pond due to recurring deposition after flood becomes shallow. Hence it suggested that

the deposited material may be utilised as borrow material. As a result, the depth will increase resulting in increased water holding capacity of the pond.

38

No vehicles or equipment should be parked or refuelled near water-bodies, to avoid contamination from fuel and lubricants

The slopes of embankments leading to water bodies should be modified and rechannelised to prevent entry of contaminants.

Chute drains shall be provided to drain surface runoff and prevent erosion from slopes.

Substructure construction should be limited to the dry season and cofferdams may be constructed and utilized to lift the spoil directly out of it and carried to the river bank for land disposal.

Large construction camps shall be avoided along the alignment and located away from habitation and water bodies. Construction labourers shall be preferable from local population. Sewage from labour camps will be treated through septic tanks. No untreated sanitary wastewater shall be discharged into surface water bodies.

Operation Stage

137. No major or long-term impact is anticipated during the operation phase on the surface water bodies due to the project implementation activities. Oil-contaminated runoff from the road during monsoon will have minimal impacts considering their low concentration However, regular checks shall be done along the alignment to ensure that flow of water is maintained through cross drains and other channels to avoid their blockade/ choking.

9. Hydrology and Drainage

Design and Construction Stage

138. Some parts of the project road passes through areas liable to submergence. Overtopping was reported in sections close to Daha River. Submergence is mainly due to reduced river capacity in the area coupled with drainage congestion. Flooding may get aggravated due to construction of high embankment road acting as impediment to flood flow particularly in the absence of adequate cross drainage/side drain structures and other engineering measures. Water logging along the road will also have ill effect on the stability of embankment especially in the area of shallow water table.

139. Diversion of water channels during construction of cross drainage structures or otherwise is not envisaged.

Mitigation Measures

Adequate cross drainage structures shall be provided to facilitate natural flow of water. Additional balancing culverts shall be provided in flood prone areas. The embankment height shall be designed consistent with the existing topography of the region.

The design of drainage system such as surface and sub-surface drainage shall be carried out as per IRC: SP: 42 and IRC: SP: 50. Surface runoff from the main highway, embankment slopes and the service roads shall be discharged through longitudinal drains, designed for adequate cross section, bed slopes, invert levels and the outfalls. If necessary, the walls of the drains shall be designed to retain the adjoining earth.

39

Bridge site shall not be selected on sharp bends and unprotected banks. Otherwise adequate bank protection/river training structures shall be provided to avoid meandering.

IRC: 34-1970: Recommendations for road construction in waterlogged area and IRC: 75 and MOSRTH guidelines for Design of High Embankments shall be referred.

The height of the embankment based on the final road levels. The following principles shall be followed for fixing the road level: (i) top of sub-grade is at least 1.0m above the high flood level/high water table/pond level and in exceptional circumstances a minimum difference of 0.6 m between the top of sub-grade and HFL/high water table/pond level. (ii) road level of the new two-lane carriageway not lower than the existing carriageway unless it improves vertical profile and also satisfies all other requirements set out in the Manual. (iii) fulfill the minimum free board requirement and provide smooth vertical profile for portions forming approaches to structures. (iv) raise the level of stretches of the existing road from drainage considerations.

The structural features and design of embankment considerations are: (i) embankment designed to ensure the stability of the roadway incorporating only those materials, which are suitable for embankment construction as per Section 5 of the Manual. ii) Side slopes not be steeper than 2H:1V unless duly designed slope protection measures are provided. iii) where the embankment is supported on a weak stratum necessary special design of the embankment done and also adopts appropriate remedial / ground improvement measures. iv) high embankments (height 6 m or above) in all soils designed from stability considerations as per IRC: 75 and MOSRTH – Guidelines for Design of High Embankments. v) The side slopes protected against erosion by providing turfing/vegetative cover, stone/Cement Concrete block pitching, geo-synthetics, gabion walls or any other measures depending on the height of the embankment, type of soil involved and susceptibility of soil to erosion as pr IRC: 56. Pitching works on slopes shall be as per MOST Specifications.

Operation Stage

140. Regular removal/cleaning of deposited silt shall be done from drainage channels and outlet points before the monsoon season. Rejuvenation of the drainage system by removing encroachments/ congestions will be regularly conducted.

B. Impact on Biological Environment

1. Terrestrial Ecology

141. There are no national parks, wildlife sanctuaries or any other similar eco-sensitive areas in the project area. However, some trees are likely to be affected. The impact and mitigation due to tree cutting has been discussed in following paragraphs.

Design and Construction Stage

142. One month before the construction starts, clearing and grubbing will be performed by the contractor. All trees within the ROW with 300mm diameter at 1m

40

above the ground will be cut, including the removal of stumps. All stumps and roots of trees of girth more than 33 mm at above 1 m from the ground level will be culled.

143. There are 821 trees likely to be affected due to the project. Most of the roadside trees are non-fruit bearing in nature. The cutting of trees will have minor to negligible impact on local environment. Moreover, this will be temporary since large number of trees have been planned to be planted on both sides of the road. This will improve the local climatic conditions in long term.

Mitigation Measures

144. Requisite permission from forest department shall be obtained for cutting of roadside trees.

145. The project envisages plantation of approximately 2,463 trees along both sides of road as per IRC SP: 21 specifications. This will include the compensatory plantation as per prevailing guidelines of State‟s forest department on 1:3 basis replacement rate. Besides, additional plantation shall be done on river banks near bridge sites to enhance the aesthetics and check soil erosion. All tree plantations will be carried out in close consultation with forest department.

146. A range of 10-15 m center-to-center is recommended for spacing of trees. Setback distance of trees in different situations shall be based on IRC: SP: 21 and IRC: 66. The distance between the kerb, if any, and the nearest edge of tree trunk shall be at least 2 m. The plantation in median shall comprise shrubs whose height would normally not exceed 1-1.5 m and shall be as per IRC SP: 21.

147. For safe traffic operation, vertical clearance between the crown of the carriageway and lowest part of overhang of the tree available across the roadway shall conform to the standards laid down in IRC: SP: 21. The pit size, fencing, watering and manuring requirements shall also conform to the above standard. Excess use of pesticides shall be restricted. Planting shall be such that it does not obstruct the visibility of traffic from any side and shall be pleasing in appearance.

Operation Stage

148. No direct impact is anticipated during operation stage except accidental damages or absence of proper tree management.

Mitigation Measures

149. Arrangement shall be made to ensure survivability of the tree plantation. The Social Forest Department or Divisional Forest Offices shall be consulted or involved in this programme. The tree survivability audit shall also be conducted at least once in a year to assess the effectiveness of the programme.

2. Aquatic Ecology

Design and Construction Stage

150. Large scale/organised fishing was not observed in the rivers/water bodies of the project area. However, small scale fishing is being carried out in Daha River and some ponds in the subproject area. There is no breeding or spawning ground in the river of the project road area.

151. Temporary sedimentation and water quality deterioration is expected from the project during the construction stage. Improvement of existing embankments particularly

41

along the waterways will increase silt while accidental spill of materials, chemicals, and fuels will deteriorate receiving water quality.

Mitigation Measures

Construction of bridge is recommended during summer season.

Best construction practices shall be adopted to prevent increase in siltation level of the water.

Siltation shall be avoided by measures suggested above.

Operation Stage

152. No impact is envisaged during operation phase of the project and hence no mitigation proposed.

C. Management of Construction Debris/Waste

153. Construction debris will be generated from pavement dismantling, quarry dust, unused iron bars, damaged support structures. Mitigation for solid waste from construction camp has been given in construction camp section.

Mitigation measures

The existing bitumen surface can be utilized for paving of cross roads, access roads, and paving works in construction sites and camps, temporary traffic diversions, haulage routes etc.

All excavated materials from roadway, shoulders, verges, drains, cross drainage and the like will be the property of the BRCDL and will be used for backfilling embankments, filling pits, and landscaping.

Unusable debris material should be suitably disposed off at pre-designated disposal locations, with approval of the concerned authority. The bituminous wastes shall be disposed in secure landfill sites only in environmentally accepted manner. For removal of debris, wastes and its disposal MOSRT and H guidelines should be followed.

Unusable and surplus materials, as determined by the Project Engineer, will be removed and disposed off-site.

154. The locations of dumping sites should be selected with following considerations.

Unproductive/wastelands shall be selected for dumping sites.

Away from residential areas and located at least 1,000 m downwind side of these locations,

Dumping sites do not contaminate any water sources, rivers etc, and

Dumping sites have adequate capacity equal to the amount of debris generated.

Public perception and consent from the village Panchayats about the location of debris disposal site has to be obtained before finalizing the location.

155. Form works will be re-used to the extent possible, more than 20 times as dictated by good practice. All stripped formworks will be examined for any damage and rectified in the workshop for re-use. Rectification includes plugging holes, and straightening bent steel props.

42

D. Socio-Economic Impact

156. Assessment of project impact on socio-economic conditions point to the conclusions that positive benefits are many fold compared to its adverse impact with the only irreversible impact is loss of some agricultural land. Other negative impacts are loss of common property resources, problem in accessibility and community linkage, health and safety during and after construction, and temporary change in demographic configuration which are readily mitigated with minor to negligible residual impacts.

1. Impacts due to Construction Camp and Immigration of Workers

157. Poor sitting and improper management of construction camp may lead to several adverse impacts on environment to include: (i) loss of vegetation due to use of wood as fuel source for cooking (ii) deterioration in nearby surface water bodies‟ quality (iii) compaction and contamination of soil due to uncontrolled disposal of solid waste (iv) poor sanitation may result to transmission of communicable diseases among the workers and the host communities. This include the possible spread of sexually transmitted disease, diseases from improper handling and supply of foodstuffs, poor water supply, insect-borne diseases, and alcoholic and drug.

Mitigation measures

158. Limited productive land should be utilised for construction camp. All sites must be graded, ditched and rendered free from depressions to avoid water stagnation. Accommodation and ancillary facilities including recreational facility for workers shall be erected and maintained to standards and scales approved by the resident engineer. All camps should maintain minimum distance of 500 m from habitation and water bodies.

159. All construction camps shall be provided sanitary latrines and urinals with provision of septic tanks attached with soak pits.

162. The Contractor will ensure that sufficient supply of suitable and hygienically prepared food at reasonsable price is available to the workers.

43

163. The Contractor will provide adequate and safe water supply for the use of the workers.

164. The Contractor will ensure that all precautions to protect the workers from insect and pest to reduce the risk to health. This include the use of insecticides which should comply with local regulations.

165. No alcoholic liquor or prohibited drugs will be imported to, sell, give, and barter to the workers of host community.

166. Migrant workers may be the potential carriers of various diseases. Local community may get exposed to the diseases carried by migrant workers. Regular health check-up and immunization camps shall also be organized for the workers and nearby population.

2. Safety of Construction Workers and Accident Risk to Local Community

Design and Construction Stage

167. Road campsites where heavy equipment and plant operations are undertaken and active road construction fronts provide hazardous environments to workers, road users, and host villages.

Mitigation measures

contractors shall be required to adopt and maintain safe working practices. Internationally accepted and widely used safety procedures should be followed during: (i) road works (ii) handling of large construction equipment and machineries, (iii) handling of chemicals and hazardous materials and inflammable substances (iii) welding, and (iv) electrical works. A set of mitigation measures for construction workers have been provided in EMP matrix table.

Contractor shall arrange all PPEs for workers, first aid and firefighting equipment at construction sites. An emergency plan shall be prepared duly approved by engineer in charge to respond to any instance of safety hazard. The contractor will be required to appoint an Accident Prevention Officer (APO) who will conduct regular safety inspections at construction sites. The APO will have the authority to issue instructions and take protectective measures to prevent accidents.

Grade separated intersections/junctions shall be provided at all major intersections in consistent to IRC: 92

Pedestrian/cyclist and cattle passageways shall be provided near identified locations. These facilities shall be planned in accordance with the relevant provisions contained in IRC-11, IRC-17 and IRC-103. The crossing facilities can be designed either in conjunction with grade intersections or through underpasses. The road embankment will be high in most of its reaches hence, the cross drainage structures can be designed such that it can be utilised as underpass by pedestrians/ cattles/animal driven vehicles/tractors

To avoid disruption of the existing traffic due to construction activities, comprehensive traffic management plan shall be drawn up by the concessionaire. Traffic in construction zones shall be managed as per the provisions of IRC SP 55.

44

After construction is completed in a particular zone, it shall be opened for normal operation. All diversions/access roads should l be closed before start of normal operation.

Use of retro-reflectorized traffic signs, and cantilever/gantry types overhead signs, thermoplastic road marking paints, delineators, traffic cones, empty bitumen drums, barricades, and flagmen will be used to ensure traffic management and safety. Conduct of regular safety audit on safety measures adopted during construction. The audit will cover manpower and their safty, machinery, temporary works, equipment and vehicles, materials storage and handling, construction procedures, environment, site safety guidelines, and miscellaneous services.

171. The Project Highway shall be provided with crane(s) with capacity to tow-away the breakdown vehicles.

172. In case of budgetary constraints, the executing agency can coordinate with operating agency of intersecting Highways to have common facilities and can bear the cost on shared basis.

3. Obstruction and Disruption of Traffic

Construction Phase

173. Disruption of access to infrastructure or social resource due to construction activity will cause nuisance and to a certain extent additional cost to the public in terms of longer travel period due to diversion or heavier traffic. It will also pose risk of accident to motorist at night if these blockages and disruption are not clearly demarcated.

Mitigation Measures

The contractor will submit a Traffic Plan to the Project Engineer at least two weeks before the construction starts that will result to obstruction. The plan will include a drawing of temporary diversions and details of arrangement. A section of the Traffic Plan will be a Control Plan that details how the safety of the pedestrians and workers and delineation of the roadway at night. This Plan will recommend for approval the safe and convenient temporary diversion of traffic during construction, design of barricades, delineators, signs, markings, lights, and flagmen, among others.

45

For widening of existing carriageway and part of it will be used for passage of traffic, paved shoulder will be provided on one side of the existing road by the contractor with the following minimum requirements:

At least one 3.5 m lane to remain to traffic at all times.

The surface used by the through traffic will be firm bituminous compacted surface free of defect

The maximum continuous length over which construction under traffic may take place is limited to 750 meters.

Construction activity will be restricted to only one side of the existing road.

On stretches where it is not possible to pass the traffic on the part width of existing carriageway, temporary paved diversions will be constructed. These paved diversions will comply with standards on junctions and temporary cross drainage.

Transportation of quarry material to the construction sites through heavy vehicles shall be done through existing major roads to the extent possible. This will restrict wear and tear to the village/minor roads. Small vehicles/unmotorised vehicle can also be used for its further transportation to the construction sites from temporary storage areas.

4. Transports and Storage of Materials

174. The construction material primarily will consist off aggregate, sand, cement, bitumen, lubricating oil and fuel for vehicle and construction equipment. These will be primarily stored temporarily at construction camps. Oils, fuels and chemicals will be stored on concreted platform with spills collection pits. Cement will be stored under cover. All these temporary storage areas will be located at least 150 M away from the habitat. The likely impacts due to transportation and storage including fugitive emission have already been covered under different section above.

5. Impact on Land and Private Properties

175. The assessment made by the resettlement expert shall be referred for exact loss of private properties and measures to compensate such losses. Environmental screening of resettlement sites, if required for the project, shall be carried out. Besides monetary compensation for any loss of private trees, compensatory afforestation and extensive plantation has been incorporated in the EMP to have long-term environmental benefits.

176. Income restoration measures/livelihood options for vulnerable group/resource poor sections and other affected persons as recommended by social development/resettlement expert shall be implemented.

6. Impact on Common Property Resources

177. There are various types of community structures/ facilities/utilities along the proposed alignment. Geometric adjustments have been made to minimize the loss to any such facilities. Any such structures even falling within ROW but out of required formation width shall be saved. Alternate access has to be provided to these structures during construction stage. All community structures likely to be dismantled shall be suitably relocated. The list of school and ponds has already been mentioned earlier in

46

this chapter. Besides, there are few hand pumps also likely to be affected. The impact on other community properties has been provided in the Table below. For exact extent of impact on these structures and mode of compensation, resettlement/land acquisition plan shall be referred.

6. PUBLIC CONSULTATION AND INFORMATION DISCLOSURE

A. Consultation Method and Information Disclosed

178. Consultations were held with all stakeholders‟ viz. beneficiaries, local and affected people, government bodies, and non-governmental organizations with intent to understand their concerns, apprehensions, and overall opinion. Informal meetings and interviews were organized covering the entire project stretch. The informal consultation generally started with explaining the subprojects, followed by an explanation to potential impacts. Participants‟ views were gathered with regard to loss of agricultural land, borrow areas, air and noise quality of the area due to traffic, water availability, and accident risk. The discussions were primarily focussed on to receiving maximum inputs from the participants regarding their acceptability and environmental concerns arising out of the project. They were given the brief outline of the project to which their opinion was sought. Suggestions were also sought for mitigating any potential adverse impact.

B. Compliance with Relevant Regulatory Requirements

179. In India, public consultation is mandatory in case of Category A and B1 category projects5 in select conditions. Public hearing is required for the proposed project which shall be conducted by Bihar State Pollution Control Board once BSRDCL applies to SEIAA/MoEF for granting of environmental clearance. However, being a Category B project based on ADB Environmental Guidelines 2009, meaningful consultation was carried out during the early stage of IEE report preparation. The requirement of public consultation during the implementation of the project has been proposed as part of the mitigation plan.

180. Public consultation was undertaken consistent with the ADB requirements. All the five principles of information dissemination, information solicitation, integration, co-ordination and engagement into dialogue were incorporated in the consultation process. A framework of different environmental impacts likely from the project was strengthened and modified based on opinions of all those consulted, especially in the micro level by setting up dialogues with the village people from whom information on site facts and prevailing conditions were collected.

C. Consultation with Executing Agency

181. Following the successful awards of 4 civil works packages under BSHP-II, Loan No. 2663-IND, substantial amount was saved and upon ADB Mission‟s suggestion SH-89:Siwan-Siswan was included as the fifth package based on preparedness. Officials of executing agency provided technical information‟s about the project. All issues related to effective implementation of EMP, grievance redressal mechanism, various clearances/consent and permission required prior to and during implementation were discussed.

5 As per schedule I of EIA notification number S.O. 1533, dated 14

th September 2006. This notification also defines when

a public consultation is mandatory.

48

D. Consultation with other Government Departments

182. All relevant government departments/agencies, which include forest, pollution control board, water resources and flood control were consulted for collection of available information their views/ comments and suggestions about the project.

183. Forest officials informed that the road side linear plantation is under protected status in its intermittent stretches. Hence, permission/forest clearance for felling of roadside trees and diversion of forest must be obtained prior to civil works. Compensatory afforestation shall be done on 1:3 basis However, the project area does not comprise any endangered floral and fauna species. Official expressed their willingness to extend all cooperation in compensatory afforestation work.

184. Pollution control board officials informed that the project area is largely devoid of industries. Hence, baseline information of the area is not available. They mentioned about need for obtaining necessary clearances from concerned authorities and NOC from pollution control board and emphasized that all conditions of such clearances shall be implemented strictly both during construction and operation phase of the project.

185. Directorate of Economics and statistics was consulted for obtaining latest facts and figures especially on socioeconomic aspects of the state and project districts.

186. The list of government officials contacted, along with purpose/objective has been summarized below.

7. ENVIRONMENTAL MANAGEMENT PLAN AND GRIEVANCE ADDRESSAL MECHANISM

A. Environmental Management Plan

191. The project specific Environment Management plan has been formulated with an aim to avoid, reduce, mitigate, or compensate for adverse environmental impacts/risks and propose enhancement measures. This includes: (i) mitigation of potentially adverse impacts; (ii) monitoring of impacts and mitigation measures during project implementation and operation; (iii) institutional capacity building and training; (iv) compliance to statutory requirements; and (v) integration of EMP with Project planning, design, construction and operation.

192. The environmental management plan highlighting potential impacts, mitigation measures, legislative requirements, time frame and institutional responsibility are given in Appendix 7.1.

B. Other Mitigation Plans

1. Resettlement Plan

193. Similarly, resettlement plan is being prepared to address issues related to involuntary resettlement. The interlinked concern, which has direct bearing on environment, has also been captured in environmental assessment and mitigation plan.

2. Emergency Response Plan

194. Assessment of nature, type, and extent of project activities establishes that accidents on paved roads and consequent spillage can be the more frequent emergency. Other emergent situation includes breach in the embankment due to heavy flood, vehicular accidents, and spills. It is suggested to develop a communication and response system to minimize the response time. The project authorities shall be prepared to counteract against such emergency either by developing in-house capabilities or by associating with any competent agency.

3. Environmental Monitoring Program (EMoP)

195. The environmental monitoring programme is devised with the objectives to: (i) evaluate the effectiveness of the proposed mitigation measures and the protection of the ambient environment as per prescribed standards, (ii) suggest improvements in the management plans, if required, (iii) verify the statutory compliance and community obligations, and (iv) use as tool to compare the monitored data against the baseline condition collected during the study period and assess the changes in environmental quality in the project area. This will be used as performance indicators for the project. This shall not only help in assessing the change due to the project activities, but also the potential impacts due to project activities.

52

a. Performance Indicators and monitoring schedule

196. Physical, biological and environmental management components identified as of particular significance have been suggested as indicators. A comprehensive monitoring plan for all performance indicators has been prepared for all stages of subproject and provided as Appendix 7.2. This includes parameters to be measured, methods to be used, sampling locations, frequency of measurements, detection limits, cost and responsibility for implementation and supervision.

b. Reporting Mechanism for Environmental Monitoring Program

197. Reporting system provides the necessary feedback for subproject management to ensure quality and timely implementation of the works. It is essential to prepare the reporting system such that flow of information from field to the BSRDCL headquarters and to the funding agency is at regular intervals. The rationale for a reporting system is based on accountability to ensure that the measures proposed as part of the Environmental Management Plan are implemented in the project.

198. Before the civil works starts, the environmental engineer of supervision consultant shall devise format for reporting the status and progress of environmental monitoring. Format shall be designed keeping in mind the compliance conditions of environmental clearance and consent to establish also. The duly filled up reporting form shall be submitted by the contractor on monthly basis to supervision consultant except for setting up of temporary facilities which shall be submitted once before start of the road construction works. The report on pollution monitoring for air, noise, soil, and water shall be submitted quarterly as envisaged in the monitoring plan. The accident report is desirable only in case of its occurrence. The supervision consultant after verifying its compliance will send his report to CGM at HQ with a copy to PIU. The Manager (Technical) for Social and Environment will monitor the effectiveness of EMP implementation.

199. The quarterly reports of the management measures will form an integral part of Quarterly Progress Reports that may be submitted to the funding agency. As per the requirements of ADB for category B projects an annual monitoring report will be prepared for disclosure on the ADB website. Additional compliance reports to MoEF regional office and SPCB required as a part of environmental clearance process and consent to establish shall also be prepared and submitted based on these monitoring and reporting formats.

c. Institutional Setting and Proposed Implementation Arrangement

200. GOB has recently setup the Bihar State Road Development Corporation Limited (BSRDCL) to streamline decision-making and provide more autonomy for project execution and delivery. This will act as Project Management Unit fully dedicated for the Bihar State Highways Project. The technical wing of BSRDCL is headed by Chief General Manager (CGM) supported by a technical advisor at Head Office. General Managers (Projects) will have overall responsibility for implementation of projects. For implementation of EMP/RP, an environment, social development and resettlement cell (ESDRC) has been set up in BSRDCL. The cell is headed by a Deputy General

53

Manager (DGM) and will consist of two managers supported by secretarial staffs. DGM (Environment and Social) is responsible for coordinating the environmental related work of the corporation and coordinate with ADB to monitor all environmental requirement of this project.

201. For subproject planning and implementation, Project Implementation Unit/s (PIUs) has been established. This is headed by Project Director (PD)/Deputy General Manager (Tech) at the subproject level. He is supported by Manager (Technical) (social and environment). PIU will supervise contractors engaged for execution of civil works under their jurisdiction. The manager Technical at PIU is responsible for managing environmental concerns of the project and implementing the EMP. The monitoring of EMP implementation in field will be carried out by the field officers of BSRDCL and supervision consultants (SC). Pollution Monitoring shall be conducted by contractor through approved monitoring agency after consent from DGM (Environment and Social) from HQ. Operation stage monitoring will be conducted by PMU through Pollution Control Board or any approved monitoring agency.

202. The EMP (mitigation plan) will be included in the construction contract and the contractor will be responsible for its implementation. BSRDCL will monitor the implementation of these mitigation measures by the contractors through environmental officer of its SC and Engineer in charge at site. These site engineers are responsible for the field level monitoring of projects.

203. The roles and duties of various agencies responsible for Monitoring have been outlined in the succeeding Table. The flow diagram depicting the institutional arrangement for implementation EMP and EMoP has been given in the following Table.

8. CONCLUSIONS AND RECOMMENDATIONS

A. Conclusions

208. Environmental Assessment of the subproject ascertains that the project is unlikely to cause any significant environmental impacts and hence categorized as category B. Most of the impacts are localized and temporary in nature and can be mitigated with minor to negligible residual impacts. The project received immense support from local people with some concern and apprehension related to compensation for land and structures. The local people appreciated that besides providing an all-weather efficient connectivity to large populations (majority of them are rural and in flood-affected areas) and improving the traffic scenario in the region, it will bear out several other positive benefits.

209. The alignment does not pass through or located nearby any national park, wildlife sanctuary, reserved forest or any other ecologically sensitive or protected areas. No archaeological/protected monument is located in the project vicinity. The land use pattern around the alignment is predominantly agricultural.

210. Sections of the SH-89 are prone to flooding particularly near Daha River. Submergence is mainly due to reduced river capacity in the area coupled with drainage congestion.

211. An estimated 972 trees will be cleared needing forest clearance from the Forestry Department. This will be mitigated, among others, through a 1:3 compensatory plantation scheme.

212. The significant impact during construction is mainly associated with minor increase in dust borne air pollution, increased noise level, nuisance due to movement and operation of vehicles, establishment of temporary facilities, hindrance in accessibility to common property resources etc. During operation stage the main impact may be on the surface water hydrology since the construction of a road across several river/rivulets in the flood affected sections can act as impediment to natural flow of water. Other issues relates to road safety including pedestrian and cattles.

213. Other than the permanent change in land use, all identified impacts are short-duration and co-terminus with the construction phase, and are easy to mitigate. All private lands that will be converted, including structures that will be relocated will be justly compensated in compliance to existing laws.

214. In general, the sub-project received immense support from local people. The local people appreciated that besides providing an all weather efficient connectivity to large populations (majority of them are rural and in flood affected areas) and improving the traffic scenario in the region, it will bear out several other positive benefits.

215. The initial environmental examination of the sub-project ascertains that the project is unlikely to cause any significant environmental impacts. No additional studies or need of undertaking detailed EIA is envisaged at this stage. The Executing Agency shall ensure that EMP and EMoP is included in Bill of Quantity (BOQ) and forms part of bid document and civil works contract. The same shall be revised if necessary during project implementation or if there is any change in the project design and with approval of ADB.

INDIA/Bihar State Highway Project: SH-89: Siwan-Siswan

SARD/SATC

59

Screening Questions Yes No Remarks

encroachment on historical/cultural areas; disfiguration of landscape by road embankments, cuts, fills, and quarries?

X The topography of the SH-89 is predominantly flat throughout the stretch. Important settlements along the project road are Siwan, Surapur, Chhapiya, Gopalpur, Sahuli, Nawada, Hasanpura, Jalalpur, Simri, Rajjanpura, Madhawapur, Rampur, Bhagwanpur Ghurghar, Chandpur and Siswan. Minor impacts on landscape due to road embankment repair and upgrading. No encroachment of historical place will occur. However, some temples and shrines exist along the road which may get impacted. No new quarries will be opened. Earth material will be sourced from the side of the road within the ROW with provision of adequate drainage. All borrow areas will be rehabilitated in accordance with applicable IRC guidelines.

encroachment on precious ecology (e.g. sensitive or protected areas)?

X There are no national parks, wildlife sanctuaries, or any similar eco-sensitive areas in the project area. A total of 821 trees will be cleared along the ROW. These avenues (both sides), are classified as forestland.

alteration of surface water hydrology of waterways crossed by roads, resulting in increased sediment in streams affected by increased soil erosion at construction site?

X The proposed road section will cross the Daha River, the only perennial river in the area at the northern end of Chainpur. No impacts on the river are expected as the existing bridge is adequate and will not be the subject of upgrading under this project. Ponds located between 26

o9‟43.10”N,

84o21‟48.72”E and 29

o9‟39.84”N,

84o21‟48.05E, and 26

o8‟54.72N,

84o21‟41.51E and 26

o8‟36.82‟N and

84o21‟38.88E are at risk of getting silted

due to earth filling to increase final road surface elevation. All drainage courses will be maintained to avoid alteration in surface hydrology. All temporary top soil stockpiles will be designed so that runoff will not induce sedimentation of waterways and ponds.

deterioration of surface water quality due to silt runoff and sanitary wastes from worker-based camps and chemicals used in construction?

Adequate sanitary facilities and drainage in the workers camps will help avoid this risk. As the construction will contain limited amount of hazardous substances and are located away from water bodies, the risk of water quality deterioration is minimized.

60

Screening Questions Yes No Remarks

increased local air pollution due to rock crushing, cutting and filling works, and chemicals from asphalt processing?

X Local air quality is expected to deterioration during construction stage particularly in dry season, and along active construction fronts and construction camps. Appropriate distance from settlement areas and dominant wind directions will be considered in locating camp site, storage areas, and construction plants (hot mix, concrete batching, and rock crusher) that generate dust and fumes.

risks and vulnerabilities related to occupational health and safety due to physical, chemical, biological, and radiological hazards during project construction and operation during project construction and operation?

X Road construction offers a variety of occupational hazards due to workers activities near rotating and moving parts, vibration and noise, electrical, welding and hot work, and site driving. The most hazardous of which are along the active road construction fronts and plants operation. The construction camps where workers eat, sleep, and rest also provides health hazards from communicable diseases. Mitigation measures include the maintenance workplace integrity, fire precautions (HMP and vehicle repair shop), provision of potable water supply, clean eating area, adequate lavatories and showers, clear delineation of safe access inside the camp, and provision of first aid. The contractor‟s safety and environment officer(s) will ensure that each worker receives adequate OHS training, equipment and hazardous materials are properly labeled, hazard codes are communicated, and area signages are maintained inside the camp.

61

Screening Questions Yes No Remarks

noise and vibration due to blasting and other civil works?

X Blasting is not involved.

Ambient noise level is expected to increase in the range of 80-90 dB(A) due to various construction activities, maintenance workshops, and earthmoving equipment. Although this level of noise exceeds National Standards, their occurrence will be intermittent and coterminous with the project construction. Impact due to noise during construction activities will be minimal to inhabitants since most of the built-up areas are located at safer distance from the road. However, there are few noise sensitive locations especially schools close to the alignment that will be affected. Impact due to noise to the workers and local community will be avoided/minimized by adequate mitigation measures which include maintenance of buffer distance, scheduling of noisy activities, and installation of sound barriers.

dislocation or involuntary resettlement of people?

X No off-site (beyond ROW) dislocation will take place

dislocation and compulsory resettlement of people living in right-of-way?

X Minor, since expansion is mostly within existing ROW.

disproportionate impacts on the poor, women and children, Indigenous Peoples or other vulnerable groups?

X None. The proposed road will assure equal pay to women. Women, poor, and dislocated people will be given priority in hiring laborers. No children/minors will be employed by the Project. During project operation, the proposed road will provide better accessibility and increase opportunity for women to establish transport related livelihood, transport their products to Siwan, and have better access to health services. Children will also benefit from easier access to tertiary-level schools.

other social concerns relating to inconveniences in living conditions in the project areas that may trigger cases of upper respiratory problems and stress?

X Deterioration in ambient air quality will be localized and temporary during construction activity. The project area is largely located in vast open areas and air dispersion characteristics are enough to avoid the generation of air quality “hot spots.”

hazardous driving conditions where construction interferes with pre-existing roads?

X To minimized the impact suitable traffic management plan will be designed and implement by the contractor

poor sanitation and solid waste disposal in construction camps and work sites, and possible transmission of communicable diseases (such as STI's and HIV/AIDS) from workers to local populations?

X Proper provisions for sanitation, health care and solid waste disposal facilities will be available in the contract documents to avoid such possibility. Workers will be made aware about the prevention of communicable diseases.

62

Screening Questions Yes No Remarks

creation of temporary breeding habitats for diseases such as those transmitted by mosquitoes and rodents?

X No such condition is anticipated, All borrow pit areas will comply with national standards. Borrow areas, will be promoted for fish culture and will naturally control mosquitoes. Incidence of malaria will be monitored.

accident risks associated with increased vehicular traffic, leading to accidental spills of toxic materials?

X Adequate safety measures will be adopted to avoid such conditions

increased noise and air pollution resulting from traffic volume?

X Increase in noise and air pollution is expected during construction phase. Adequate mitigation measures will be adopted to minimize them. During operation phase, the main source of noise and air will be the motorized road users. Improved road conditions, extensive plantation including multilayered plantation near sensitive locations will help reduce the noise and air impact.

increased risk of water pollution from oil, grease and fuel spills, and other materials from vehicles using the road?

X Controlled construction activities and proper drainage system will reduce this possibility.

social conflicts if workers from other regions or countries are hired?

X Laborers will be sourced primarily from local communities to reduce conflict.

large population influx during project construction and operation that causes increased burden on social infrastructure and services (such as water supply and sanitation systems)?

X The size of the constructions camp, similar to the previous BSHPs, will not be expansive as labor and materials will be primarily sources locally. All water extraction will be covered by necessary permits to avoid negative impacts to the host communities.

risks to community health and safety due to the transport, storage, and use and/or disposal of materials such as explosives, fuel and other chemicals during construction and operation?

X 3rd

party supplier and transporters of bitumen and fuel will be required to demonstrate capability to contain accidental spills especially during transport.

Within the construction camp, all loading and unloading of these materials will be supervised by the safety officer and only in designated areas

community safety risks due to both accidental and natural causes, especially where the structural elements or components of the project are accessible to members of the affected community or where their failure could result in injury to the community throughout project construction, operation and decommissioning.

X Natural causes of structural failures will involve extreme flooding and earthquake. The flood prone section in the entire SH-89 is from Hassanpura area up to Ghurghut including the Chainpur main market area. The entire SH is under Zone IV seismicity category having high damage risk to earthquakes. Adequate sizing of cross drains will be made in Hassanpur to Ghurghut and Chainpur market, while road design has incorporated corresponding ground acceleration to protect against strong earthquake.

63

Note: Hazards are potentially damaging physical events.

Climate Change and Disaster Risk Questions

The following questions are not for environmental categorization. They are included in this checklist to help identify potential climate and disaster risks.

Yes No REMARKS

Is the Project area subject to hazards such as earthquakes, floods, landslides, tropical cyclone winds, storm surges, tsunami or volcanic eruptions and climate changes (see Appendix I)

X Project area is located in high damage risk zone w.r.t seismicity (Zone IV) All civil structures have been designed as per relevant IS Codes corresponding to seismic zones.

Could changes in temperature, precipitation, or extreme events patterns over the Project lifespan affect technical or financial sustainability (eg., increased erosion or landslides could increase maintenance costs, permafrost melting or increased soil moisture content could affect sub0-grade).

X Increase in marginalization is not expected. Project will cause upliftment of socio-economic conditions including reduction of migration.

Are there any demographic or socio-economic aspects of the Project area that are already vulnerable (eg., high incidence of marginalized populations, rural-urban migrants, illegal settlements, ethnic minorities, women or children)?

X Although now considered as one of the fastest growing state, Bihar has the lowest per capita income, 14

th lowest gross

domestic product, low literary rate, highest gross interstate migration, and weak health service.

Could the Project potentially increase the climate or disaster vulnerability of the surrounding area (e.g., by encouraging settlement in areas that will be more affected by floods in the future, or encouraging settlement in earthquake zones)?

X The project will improve existing road. This will enhance resiliency of the villagers to climate change risk, particularly to flooding as higher and reinforced embankments and properly sized side/cross drains will be constructed on sections that has experience flooding.

1. SELECTION OF BORROW AREAS

Location of borrow areas shall be finalized as per IRC: 10-1961guidlines. The finalization of locations in case of borrows areas identified in private land shall depend upon the formal agreement between landowners and contractor. If, agreement is not reached between the contractor and landowners for the identified borrow areas sites, arrangement for locating the source of supply of material for embankment and sub-grade as well as compliance to environment requirements in respect of excavation and borrow areas as stipulated from time to time by the Ministry of Environment and Forests, Government of India, and local bodies, as applicable shall be the sole responsibility of the contractor.

The contractor in addition to the established practices, rules and regulation will also consider following criteria before finalizing the locations.

The borrow area should not be located in agriculture field unless unavoidable i.e. barren land is not available.

The borrow pits preferably should not be located along the roads.

The loss of productive and agriculture soil should be minimum.

The loss of vegetation is almost nil or minimum.

The Contractor will ensure that suitable earth is available.

2. CONTRACTOR’S RESPONSIBILTY

The Contractor shall obtain representative samples from each of the identified borrow areas and have these tested at the site laboratory following a testing programme approved by the Engineer. It shall be ensured that the sub-grade material when compacted to the density requirements shall yield the design CBR value of the sub-grade. Contractor shall begin operations keeping in mind following;

(1) Haulage of material to embankments or other areas of fill shall proceed only when sufficient spreading and compaction plants is operating at the place of deposition.

(2) No excavated acceptable material other than surplus to requirements of the Contract shall be removed from the site. Contractor should be permitted to remove acceptable material from the site to suit his operational procedure, then shall make consequent deficit of material arising there from.

(3) Where the excavation reveals a combination of acceptable and un-acceptable materials, the Contractor shall, unless otherwise agreed by the Engineer, carry out the excavation in such a manner that the acceptable materials are excavated separately for use in the permanent works without contamination by the un-acceptable materials. The acceptable material shall be stockpiled separately.

(4) The Contractor shall ensure that he does not adversely affect the stability of excavation or fills by the methods of stockpiling materials, use of plants are siting of temporary buildings or structures.

71

3. BORROWING FROM DIFFERENT LAND-FORMS

(vi) Also, no pit shall be dug within the offset width from the toe of the embankment required as per the consideration of stability with a minimum width of 10m.

4. REHABILITATION OF BORROW AREAS

The objective of the rehabilitation programme is to return the borrow pit sites to a safe and secure area, which the general public should be able to safely enter and enjoy. Securing borrow pits in a stable condition is fundamental requirement of the rehabilitation process. This could be achieved by filling the borrow pit floor to approximately the access road level.

Re-development plan shall be prepared by the Contractor before the start of work inline with the owners will require and to the satisfaction of owner. The Borrow Areas shall be rehabilitated as per following;

Borrow pits shall be backfilled with rejected construction wastes and will be given a vegetative cover. If this is not possible, then excavation sloped will be smoothed and depression will be filled in such a way that it looks more or less like the original round surface.

Borrow areas might be used for aquaculture in case landowner wants such development. In that case, such borrow area will be photographed after their

73

post use restoration and Environment Expert of Supervision Consultant will certify the post use redevelopment.

The Contractor will keep record of photographs of various stages i.e., before using materials from the location (pre-project), for the period borrowing activities (construction Phase) and after rehabilitation (post development), to ascertain the pre and post borrowing status of the area.
