EXECUTIVE SUMMARY 1. The Government of Karnataka (GoK) through the Karnataka Urban Infrastructure development and Finance Corporation (KUIDFC) is implementing the North Karnataka Urban Sector Investment Programme (NKUSIP) under the assistance ofAsian Development Bank. The goal of the programme is to improve the level, quality and sustainability of basic urban services in selected Urban Local Bodies (ULBs), contributing to improved quality of life among the urban poor. NKUSIP will be implemented over a period of eight years beginning in 2008, and will be funded by a loan via the Multi-tranche Financing Facility (MFF) of the Asian Development Bank (ADB). 2. Karnataka Urban Infrastructure Development & Finance Corporation (KUIDFC) is the nodal executing agency (EA) responsible for implementing NKUSIP. Investment Program implementation activities will be monitored by KUIDFC through a separate Investment Program Management Unit (PMU). The ultimate implementation responsibility lies with ULBs in co ordination with various other Departments of GoK. 3. ADB requires the consideration of environmental issues in all aspects of the Bank‘s operations, and the requirements for Environmental Assessment are described in ADB‘s SPS (2009). This states that ADB requires environmental assessment of all project loans, program loans, sector loans, sector development program loans, loans involving financial intermediaries, and private sector loans. This Initial Environmental Examination (IEE) has been prepared for the Yadgir CMC Tranche III Sub-Project, specifically for Sewer Network and STP for Yadgir Town. An Environmental Management Plan (EMP) is proposed as part of this report which includes (i) mitigation measures for significant environmental impacts during implementation, (ii) environmental monitoring program, and the responsible entities for mitigation, monitoring, and reporting; (iii) public consultation and information disclosure; and grievance redress mechanism. 4. Detailed design began in 2010 and completed in April 2011. Construction may begin in fourth quarter of 2011, and will take around 18 months. All civil works will be completed by 2013. Yadgir town is situated on the bank of Bhima river, which is one of the tributaries of river Krishna. Yadgir is located at an altitude of 370 m above the mean sea level and its geographical coordinates is 17° 7' North latitude and 76° 57' East longitude. The city is about 300 kms from Hyderabad and 115 km from Gulbarga city. The ground levels vary from the maximum of 390.53 m to 362.65 with slopes in all directions. The subproject locations are not located in areas prone to water-logging, salinasation, and flash flood. There are no protected areas, wetlands, mangroves, or estuarines in or near the subproject location. Trees, vegetation (mostly shrubs and grasses), and animals are those commonly found in urban areas. The subproject location are not located in or near any historically-, culturally-, archaeologically- or architecturally-significant or tourists area. 5. Potential negative impacts were identified in relation to construction and operation of the infrastructure. A number of impacts and their significance have already been reduced by amending the designs thus no impacts were identified as being due to the project design or location. Mitigation measures have been developed to reduce all negative impacts to acceptable levels. 6. During the construction phase, impacts mainly arise from the need to dispose of moderate quantities of excess soil; and from the disturbance of residents, businesses, and traffic. These are common impacts of construction in urban areas, and there are well developed methods for their mitigation.
ii
7. Once the Sewer Network and STP system is operating, the facilities will operate with routine maintenance, which should not affect the environment. The impact to nearby environment is minimum. The system will treat the collected waste water as per CPCB standards and will benefit the individuals and public health with improvements in hygiene. This will reduce the incidence of disease associated with poor sanitation. This will also lead to economic gains as people will be less away from diseases, work and indirectly increase their income. 8. There were limited opportunities to provide environmental enhancements, but certain measures were included. For example it is proposed that the project will employ in the workforce people who live in the vicinity of construction sites to provide them with a short-term economic gain; and ensure that people employed in the longer term to maintain and operate the new facilities are residents of nearby communities. Mitigation will be assured by a program of environmental monitoring conducted during construction and operation to ensure that all measures in the EMP are implemented and to determine whether the environment is protected as intended. This will include observations on- and off-site, document checks, and interviews with workers and beneficiaries, and any requirements for remedial action will be reported. The stakeholders were involved in developing the IEE through face-to-face discussions on site and public meeting held at the STP site, after which views expressed were incorporated into the IEE and the planning and development of the project. A grievance redress mechanism involving an NGO and a Grievance Redress Committee at District level has been proposed under the project. 9. Therefore the subproject is unlikely to cause significant adverse impacts. The potential adverse impacts that are associated with design, construction, and operation can be mitigated to standard levels without difficulty through proper engineering design and the incorporation or application of recommended mitigation measures and procedures. Based on the findings of the IEE, the classification of the Project as Category ―B‖ is confirmed. It is concluded that the proposed sub-project should proceed, with appropriate mitigation measures and monitoring programs identified in the IEE.
I. INTRODUCTION
A. Overview
1. The Government of Karnataka (GoK) through the Karnataka Urban Infrastructure Development and Finance Corporation (KUIDFC) has prepared the North Karnataka Urban Sector Investment Programme (NKUSIP) under the Asian Development Bank assistance. The proposed NKUSIP is the logical follow-on investment program to the ongoing Loan 2312-IND. The NKUSIP is being formulated as a sector loan with a multitranche financing facility modality. The project goal is to facilitate economic growth in the five towns of North Karnataka under Package 3 and bring about urban basic services to the citizens that are environmentally sound and operationally sustainable. Outputs from several vital studies, financial assessment and social and Environmental Assessment, etc, have formed the backbone for the programme appraisal leading to approval of loan. Initial Environmental Examination (IEE) Report is considered as an important tool for incorporating environmental concerns at the project level. IEE should be carried out as early as the project planning stage as part of feasibility thus it can assure that the project will be environmentally feasible. 2. Initial Environmental Examination (IEE) of the proposed sub projects in ‗Yadgir Town’ is provided in this section following the guidelines of Asian Development Bank‘s (ADB) Safeguards Policy Statement. As the Sewer Network and STP for Yadgir Town in Trench 3 aims to improve the quality of life by significantly improving the environmental conditions of the city, the environmental impacts are expected to be low and hence a rapid assessment has been performed. The Environmental Assessment is based on reconnaissance surveys, primary and secondary data obtained during actual field surveys, analysis, and from various concerned government departments. The report describes environmental baseline condition of city, existing environmental policies and relevant legislations and administrative framework applicable for the proposed sub component of NKUSIP Package-3. The part covers environmental impacts and mitigation measures for construction and operation phases of the project. Categorisation of project impact has been identified. The Environmental Management Plan and Monitoring Plan are substantiating the IEE report. The IEE report has been prepared as per requirements of ToR of Programme Consultants‘ Services. B. Methodology
3. Environmental Assessment (EA) is the process in which environmental factors are integrated into project planning and decision making in details so as to achieve ecologically sustainable development. It aims at predict environmental impacts at an early stage in project planning and design, find ways and means to reduce adverse impacts, shape projects to suit the local environment and present the predictions and options to decision-makers. By using EA both environmental and economic benefits can be achieved, such as reduction of cost and time of project implementation and design, avoid treatment/clean-up costs and impacts of laws and regulations. The methodology adopted for the preparations of feasibility study for the environmental assessment of these sub project are as follows:
(i) Collection, documentation and analysis of environmental baseline data obtained from secondary sources and also the primary data obtained by conducting survey and field investigation,
(ii) Environmental Screening, (iii) Assessment of Environmental Effects, (iv) Mitigative Measures, (v) Preparation of Environmental Monitoring Plan and
2
(vi) Preparation of Environmental Management Plan.
1. Collection, Documentation and Analysis of Environmental Baseline Data
4. Data was obtained from secondary sources and also the primary data obtained by conducting survey, testing and field investigation
2. Reconnaissance Survey
5. The study team visited the selected alignment of sewer line and proposed Sewerage Treatment Plant. Environmental features are being carried out in this survey.
3. Collection, Collation and Analysis of Data
6. Most of the data collected from the secondary sources. However, primary data field investigation has been drawn. Secondary information was collected from state maps, town maps, census handbooks, Forest Department, Metrological Department, Water Works Deptt and other government publications as well as reports prepared for other projects and the DPR prepared under NKUSIP in 2011 for the town. The data information collected from both primary and secondary sources were collated and analysed.
4. Documentations of Baseline Conditions
7. The documentation of the baseline conditions was completed for Project Influence Zone as per the ADB Guidelines. Primary surveys were carried out for determination of field existing scenario.
5. Environmental Screening
8. Environmental screening is necessary to assess the environmental effects associated with the Project with respect to human health and natural resources. It is also required to categorise the project in terms of its environmental impacts. Environmental screening has been done in line with the guidelines provided in the SPSADB SPS (2009).
6. Assessment of Environmental Effect
9. Potentials and significant impacts were identified on the basis of analytical review of baseline data (both primary and secondary); review of land uses and environmental factors within the Project Influence Zone (PIZ). Identification of the probable environmental effects and needful actions at an early stage of the project facilitate in mitigation of the effects. The environmental effects are therefore, assessed for three stages of implementation of the project i.e. Planning and Design (Pre-Construction), Construction and Post-Construction.
7. Mitigative Measures
10. Environmental effects anticipated from the Project have been identified based on the environmental screening. Appropriate measures are needed to mitigate such effects. The environmental effects and corresponding mitigative measures required during the Pre-Construction, Construction and Post-Construction phases of the project have been identified accordingly.

8. Preparation of the Environmental Monitoring Plan and Management Plan
11. Timely actions are needed to help in mitigating the environmental effects. Consultants have therefore prepared an Environmental Monitoring Plan and Environmental Management Plan (EMP) covering environmental issues, mitigative measures and actions required. Actions required for various agencies have also been identified in the EMP. The EMP has been prepared for three phases of the project namely Pre-Construction, Construction and Post Construction phases. C. Environmental Regulatory Compliance:
12. The section discusses the existing environmental policies, relevant legislations with respect to the Sewerage sub projects and the administrative frameworks for the supervision and implementation of the provisions stipulated therein. The environmental guidelines and procedures of Asian Development Bank (ADB) have also been discussed in this section.
D. Asian Development Bank Requirements
13. ADB confirms that project proponents must include appropriate environmental and social considerations, through various measures, so as to prevent or minimize the impact on the environment and local communities which may be caused by the projects for which ADB provides funding, and not to bring about unacceptable effects. It will thus contribute to the sustainable development of regions. In making its funding decisions, ADB conducts screenings and reviews of environmental and social considerations to confirm that the requirements are duly satisfied. E. Procedures for Confirmation of Environmental Considerations
1. Screening and Categorisation
14. The sub project was screened using Rapid Environmental Assessment (REA). Checklist (Appendix 1). Given the sector and scale of the project, the substance, and degree of potential environmental impact within the environmental and social context of the proposed project site and surrounding areas, the sub project is considered Category B, requiring an IEE (Table 1)

F. Indian Environmental Law & Regulations
1. The Environmental (Protect) Act, 1986 and the EIA Notification, 2006
15. The Environmental (Protection) Act, 1986 is the umbrella legislation providing for the protection of environment in the country. This act provides the Environment (Protection) Rules, which were formulated in 1986. The Environmental Impact Assessment Notification, 2006 and
5
the various amendments thereto have been notified under this act. As per the Amendment, formal Environmental Clearance from the ministry is not required for any sewerage, drainage or water supply project
2. The Water and Air (Prevention and Control of Pollution) Acts
16. The Water (Prevention and Control of Pollution) Act, 1974 resulted in the establishment of the Central and State Level Pollution Control Boards (CPCB and SPCB) whose responsibilities include managing water quality and effluent standards, as well as monitoring water quality, prosecuting offenders and issuing licenses for construction and operational of certain facilities similarly. The Air (Prevention and Control of Pollution) Act, 1981, empowers the SPCBs to enforce air quality standards set by the CPCB. 17. The Environment (Protection) Act, 1986. The EP Act is umbrella legislation and supplements the existing environmental regulations, the Water Act and the Air Act. As per the Act, ―Central Government shall have the power to take all such measures as it deems necessary or expedient for purpose of protecting and improving the quality of environment and preventing, controlling and abating environmental pollution‖. The Act empowers the regulatory authority to ―restriction of areas in which any industries, operations or processes or class of industries shall not be carried out or shall be carried out subject to certain safe guards‖. Under this act Consent for Establishment (CFE) - Form XIII is applicable for siting STP at any place. In this project STP site is applicable for Green Category (only domestic sewage). Under this act State Pollution Control Board plays as regulatory authority to provide No Objection Certificate (NOC) for establishment of STP at particular site. 18. The Project requires the obtaining of clearances from the State Pollution Board of Karnataka pursuant to the Water (Prevention and Control of Pollution) act of 1974, the Cess Act of 1977 and Air (Prevention and Control of Pollution) Act of 1981.
3. The Ancient Monument and Archeological Sites and Remains Act, 1958
19. According to this act, area within radii of 100 m and 300 m from the protected property are designated as ―Protected area‖ and ―Controlled area‖ respectively. No development activity (Including building, mining, excavating, blasting) is permitted in the ―protected area‖ and development activities likely to damage the protected property are not permitted in the ―controlled area‖ without prior permission of the Archeological Survey of India (ASI) if the site/remains/monuments are protected by ASI or the protected by the State. The Proposed alignment is not close to any protected property and therefore, this act will not be applicable for the project.
4. Yadgir Municipal Council
20. Yadgir Municipal Council is mainly responsible for handling key responsibilities like supply of portable water, sanitation and public hygiene, public lighting, sustainable urban growth, regulation of building construction and licensing of commercial activities, etc. 21. With special reference to the sewerage system, the Yadgir Municipal Council is involved in:
(i) Operation and maintenance of proposed sewerage systems. (ii) Construction and maintenance of Sewerage lines along the road and STP within
municipal maintenance.

II. DESCRIPTION OF THE INVESTMENT PROGRAMME COMPONENT
A. NKUISIP Investment Programme Goal
26. Government of Karnataka (GoK) through the Karnataka Urban Infrastructure Development and Finance Corporation (KUIDFC) has prepared the North Karnataka Urban Sector Investment Programme (NKUSIP) under the Asian Development Bank assistance. The goal of the programme is to improve the level, quality and sustainability of basic urban services in selected Urban Local bodies (ULBs) contributing to improve quality of life among the urban Poor. The NKUSIP is consistent with GOIs urban reform objective for the Tenth Plan Period (2002-2007), which entails a reform agenda to initiate the process of:
(i) Enhancing the capacity of Urban Local bodies (ULBs) to assume their functions in accordance with the 74th Constitutional Amendments, with greater sustainability and accountability.
(ii) Strengthening local finance through rationalising and improvement of property tax, and levy of sufficient user charges;
8
(iii) Ensuring improved maintenance of existing assets; and (iv) Introducing better accounting and financial management practices.
27. The NKUSIP would provide the momentum for the overall reform by supporting these objectives in Karnataka and promoting the emergence of better functioning cities.
28. The development purpose is designed to assist Urban Local Bodies (ULBs) to ―promote good urban management, and develop and expand urban infrastructure to increase economic opportunities and to reduce vulnerability to environmental degradation and urban poverty‖. Outputs from several vital studies, financial assessment and social and Environmental Assessment, etc, have formed the backbone for the programme appraisal leading to approval of loan. B. Need for Infrastructure Improvement:
29. At present there is no hygienic system for sewage collection, treatment or disposal in Yadgir. Septic tanks are prevalent and those without septic tanks discharge effluents to open drains. Population density is very high so the septic tanks are not functioning properly. Sewage flowing through the roadside drains is visible, it is flowing into the open channels and polluting the surrounding water bodies. Solid waste is also dumped on road side drains. Most of the drains are choked. Nine public latrines have been constructed and they serve approximately 9,000 population. In areas where no public latrines are provided many people defecate on the streets or in open plots. 30. Total sewage generation within the existing municipal council has been derived by considering projected population within the CMC boundary covering 31 wards. Total sewage generation in Yadgir in the Intermediate stage (2029) and Ultimate Stage (2044) has been estimated as follows:

C. Subproject Description
31. Yadgir town is situated on the bank of Bhima river, which is one of the tributaries of river Krishna. Yadgir is located at an altitude of 370 m above the mean sea level and its geographical coordinates is 17° 7' North latitude and 76° 57' East longitude. The city is about 300 kms from Hyderabad and 115 km from Gulbarga city. It is also famous for its laminated limestone which is known as Yadgir stones. There are large deposits of limestone in and around Yadgir. The town has come into prominence on account of its big cement factory owned and run by the Associated Cement companies Limited (today under the aegis of Zawar cement). In 1954, the Yadgir Town Municipal Council (TMC) was constituted and upgraded to second grade City Municipal Council (CMC) in 2002. The town is divided into 31 wards spreading across an area of 14.95 sq. km and as per census 2001 population was 58,811 with the density of 3,933 person per sq km. Map 1 Shows the Project Area. The project area is the area under jurisdiction of Yadgir CMC.
32. The entire Yadgir town is divided in two sewerage zones. Zone I which is proposed to be implemented under NKUSIP is drainable by gravity to southern part of the city. This project includes sewerage pipeline, pumping stations and treatment plant near Hossalli Village under this Phase II Trench 3. The Proposed sewerage system is divided into two sewerage zones, out of which Zone I is planned to be implemented under Tranche 3.

III. DESCRIPTION OF THE ENVIRONMENT
A. Environmental Profile of Yadgir
40. The baseline environmental status of the project influence area is based on available secondary information and collection of primary data by conducting field survey within proposed sewer line and other components within project influence zone. It will help in assessing the magnitude of potential effect both beneficial as well as adverse due to the proposed project
12
activities on the environment. In order to assess the baseline environment conditions of the project area, the following aspects have been considered.
1. Topography & Geology
41. Yadgir is characterized by small hillocks near the centre with its top at an elevation of 539 m. From the foot of the hill, the ground slopes in all directions. However, the town slopes are towards the direction from west and south. The ground levels in the inhabited areas of the town range from 390.53 m above mean sea level to elevation 362.65 m above mean sea level. 42. Yadgir town is famous for its laminated lime stone which is known as Yadgir stones. There are large deposits of lime stone in and around Yadgir town.
2. Soil
43. The predominant soil in this town is silty-clay in nature. The top layer of soil, up to 2 m of depth consists of silt/silty clay followed by soft disintegrated rock and then hard rock. In some areas the soft layer extends up to 4 m, followed by hard strata. The size of clay is less than 0.002 mm in this region. The depth of ground water table extends between 7.5 m to 35 m below ground level. The physiochemical properties of Yadgir soil is drawn in following table:

44. The physicochemical condition of soil is not very productive. Organic component is moderate but soil is mainly acidic in nature. Moisture content is very low. The NPK value is on lower side. Even micro nutrients are almost lower end.
3. Climate
45. Yadgir town lies in the dry and arid zones. As a result of which the climate is generally dry and the mercury level rises to 41ºC or 44ºC during summers and goes as low as 12.0 ºC or 13.30 ºC during December – January in winters. The hot summer begins by the middle of February and extends up to the mid June. The town is classified as moderate to low rainfall-receiving area. Consequently, drought and scarcity conditions haunt the people of the region. The average annual rainfall in Yadgir is 728 mm with 55 rainy days, as against 720 mm of annual rainfall with 48 rainy days in Gulbarga district. The wind generally blows from south west to north east direction and north east to south west.

4. Land Use Pattern (LUP)
46. Town are mainly divided into old and an around railway station area. The total developed area is 647.00 ha of which 43.27% is the total municipal area. Nearly 20% of the total municipal land is under vacant land and 5% of land is under hillocks and water sheet. The existing LUP is shown in Table 8
Table 8: Existing Land Use Pattern

5. Water Quality
a. Surface Water
47. Both surface and subsurface sources meet water supply requirement of Yadgir. River Bhima (originating in Maharashtra) is the main surface source of water supply, which accounts for over 90 percent of the town‘s water supply. Water abstraction from Doddahalla, a natural stream, also provides surface water. Sub surface sources comprising 90 borewells and 20 open wells supplement surface source supply to some habitat concentrations, which are not covered by the water supply scheme. The yield of these sources started going down and was insufficient to meet the requirements of the Town. Flow of water of river water is not good. As a result the homeostatic mechanism of water itself becomes poor along with the course of stretch. As per CPCB Norm the standard of water quality of surface water is as follows:

49. Viewing above data it is revealed that the turbidity of water is very high. The flow of water is very poor and subsequently TDS value of water has increased. But, BOD level is within permissible limit. Even chloride is also less than limit. Overall determined factor of area is good.
b. Lake Water Quality:
50. Inland lake is another important environmental feature in Deccan Trap area. Natural lake has huge catchments area and in earlier period it was another source of drinking water. But presently, this inland water accumulated drainage water from adjacent area. Eutrophication is common feature now. In Yadgir Sannakere is another major lake in town. Overall water quality is not vey poor. PH value is within limit. Only dissolve solis is more than desirable limit and total iron content is high. But content of DO is within limit.

52. The ground water quality of Yadgir town is stated above. The hardness is very high. It may be due to geological formation of underneath aquifer. Rest parameters are permissible in this case. The overall the water quality is poor for this town . Maximum water is saline. Whole area‘s porosity is very high level. As a result the siltation process is also very high. The after effect of water TDS is more. Lots of silt and mud are coming from bore wells. Due to absence of sewer line proper drainage facility ground water is become polluted. Total hardness of water is also high it may be due to Aquifer chemical composition of area. Although, aquifer condition is basically determining factor of physical characteristics of water but the needful treatment is needed for drinking purpose over here.
d. Waste Water:
53. There is one time data available to assess the waste water of quality of Yadgir. The Environmental quality of waste water is as follow

54. Viewing above data it is reveleaded that the turbidity of water is vey high. Although, the flow of water is very poor and subsequently TDS value of water has incresed. But BOD level is more than 60 times more than permissible limit.
6. Ambient Air Quality:
55. The ambient air quality is one of the most significant indicators of environmental health of a Town. Ambient air quality monitoring has not been carried out at any point in the Yadgir Town. During site visit it is observed that SPM level is very high due to poor road side condition and very high vehicular emmission rate. To make pollution free zone there is need to control the vehicular emmission in town with proper system of fuel and proper maintenannce of road side berms. As per CPCB norms the standard for Ambient Air Quality of any particular area is as follows:

7. Ambient Noise Quality:
56. Noise can disturb our work, rest, sleep and communication. It can damage his hearing and evoke other psychological and possibly pathological reactions. This fact has been experienced widely and is a serious concern to every one. The Govt. of India has timely included noise as an air pollutant in the amended act of 1997 for which has lie down as following:
19
57. The Central Pollution Control Board in exercise of its powers under section 16 (2) (h) of the Air (Prevention and Control of Pollution) Act, 1981, notified the ambient air quality standard in response as:
Table 15: Standard of Noise Level

Industrial Area 75 70
Commercial Area 65 55
Residential Area 55 45
Sensitive Zone 50 40
Source: CPCB.
58. There is not a single monitoring station to monitor and assess the Noise level of Town. The scenario of the commercial zones is as other towns of NKUSIP – Pkg III. None of the areas are very crowded and noisy. At present no noise buffering system is provided on road side or sensitive area or even residential area.
8. Social Environment
Ethnic Minorities and Indigenous Peoples
59. No communities of ethnic minorities and indigenous people have been reported within the project area.
9. Health and Hygiene
(i) No safe disposal method does presently exist. A large number of dry latrines still exist but the night soil freely flows in the open causing serious unsanitary conditions and health hazard. The problem needs immediate attention as it pollutes the public water courses also.
(ii) The absence of municipal taps and non-availability of staff for maintenance have
resulted in the poor state of the public latrines, which are largely being used by the slum population.
10. Protected Areas
60. There are several religious monuments protected by the Archaeological Survey of India (ASI) as well as Karnataka Government and falling under the project area. The listed monuments under ASI and GoK are:
(i) Mailarlinga Temple (ii) Jama Mosque (iii) Yadgir Fort, etc
61. There is no excavation and proposed Sewer works are within the controlled area of these protected area.
20
11. Forest & Biodiversity:
62. There is no forest area demarcated within Yadgir Town limit. But some big trees are found on road and open land. There is no endangered species found. There are approximately 20 trees in total vacant land and all of them are Neem (Azadirachta Indica) category. Other than total trees throny bushes present. Overall there is no loss of precious trees. 63. There are no endangered species found within site and as peripheral areas.
12. Demographic Characteristics:
64. Population Growth: The total population of CMC is 58,811 as per census 2001. The town has experienced tremendous population growth during the last decade (34.68 % from 1991 to 2001) compared to the consistently increasing growth rate since 1930‘s. .By the yea r2029 it is estimated to grow 98,122 and for ultimate design period 2044 it will become 1,31,068. 65. The total number of households in the CMC according to the census 1991 is 9,610. The household size for Yadgir is 6.31, compared to the average national household size of 6.3 (Census 2001).
13. Socio Economic Characteristics:
66. The share of working population also known as workers participation rate (WPR) in Yadgir is 35.23 percent (2002) as against 36 percent of thr State Urban WPR. B. Environmental Setting of Investment Programme Component Sites:
Site Selection for Sewerage Treatment Plant at Hossalli Village 67. The location of the sewerage treatment plant is selected based on the natural slopes of city to provide the gravity flow till the disposal plant. The city follows the natural slope from west towards south and therefore STP location is chosen as southern site. 68. The flow for ultimate period is estimated to be 11 Mld. It has been estimated that the land requirement per Mld of sewage is 2 acres. So the total land requirement is to be 22 acre 10 Guntas. Land of 22 acre, 10 Guntas is under acquisition by KUWS & DB. 69. The Topography of the town is predominantly flat. The environmental condition is as same as city general. There is no environmental sensitive area is prevalent within project area not even 100 m of project influence zone. STP will be constructed sufficiently away from the settlement area. The sites selection has been justified because the treated effluent from the plant will be used in agriculture purposes. The sludge can be extensively used for manure process and solid waste will be dumped at disposal site.
IV. ENVIRONMENTAL SCREENING OF SUB COMPONENTS:
70. The proposed sewerage system consists of trunk mains, sub trunk mains and laterals connected to the main sewers. Old town area is congested but new area is planned. The impacts of proposed works are site- specific, and few are irreversible. In most cases, mitigation measures can be designed to minimize the impact. So this sewerage sub project will be categorized as Category B project. The detail REA checklist for sub components of sewerage sub project for Yadgir is appended in Appendix 1.

V. POTENTIAL ENVIRONMENTAL IMPACTS AND MITIGATION MEASURES
A. Overview
71. This section identifies and assesses the probable impacts on different environmental parameters during planning, construction and the operation of the proposed development. After studying the existing baseline environmental scenario, initial field surveys, reviewing the process and related statutory norms, the major impacts have been identified and assessed for the design, construction and the operation phases. Potential positive impacts or improvements are also reviewed. 72. Planning and Design covers the construction details, materials of construction etc. that ultimately decides the impact during later phases. Most of the impacts are during construction and operation phase. While some of the construction phase impacts are temporary, some are permanent. The permanent impacts would be positive in nature such as increase in business & employment opportunities, reduction in accidents, and comfort in journey. 73. Screening of environmental impacts has been based on the impact magnitude (negligible/moderate/severe – in the order of increasing degree) and impact duration (temporary/permanent). The following table shows the screening of impacts; N/T represents the lowest impact while S/P represents the highest impact. Numerator represents the Degree of Impact and denominator represents the Duration of impact.

VIII. PUBLIC CONSULTATION AND INFORMATION DISCLOSURE
A. Overview
94. A checklist of questions was kept ready and responses were elicited from people and guidelines were issued to field assistants for the purpose. The questions were kept simple for people to comprehend. Notes were made for the responses and viewpoints presented by people. The following table shows the details of it. Further Focus Group Discussions were carried out with the houses located at the nearest vicinity of STP Site. The issues raised during Public Consultation and the mitigation measures incorporated in design and IEE and presented in Table 21.
Table 21: Issues Addressed during Public Consultation along Project Area in Yadgir
S.NO Issues Raised during
Focus Group Discussion Mitigation Measures
1. Loss of Livelihood and Income restoration Options
This issue was raised by maximum number of villagers as loss of fertile land will deteriorate their income sources. Instead of lump sum money they were more interested for limited regular income. Particularly those persons whose land belongs to land. Though land is not very fertile land, so consultant was discussed and actual requirement has been told. It was discussed that there is no loss of livelihood or any displacement. But leakage and open drain intercepts sewer affects the health problem and vice versa agricultural land.
2. Water Logging and
Drainage
Participants had a fear that during construction widening and alignment of sewer, water a pipeline will alter natural drainage pattern in the area and may cause un ease situation for local people.
3. Odour and Mosquito Breeding
which will raise disease of Nandikur Village
The community raised concern on odor nuisance. The STP technology has been revised from ASP to FAL. It was also emphasized to the community that the distance of the STP is 1.8 km from the nearest habitation therefore odor nuisance is not anticipated. Regular cleaning and periodical sludge removal does not poses any health disease over area. Provision of buffer zone and landscaping has been Integrated as a part of STP which will effectively control the nuisance to the immediate surrounding.
4. Over flowing of untreated Sewage and polluting agricultural lands and
affecting livelihood of public.
STP unit is adequately sized to handle the sewage and desirable discharge limit. It won‘t affect the irrigation potentiality and not will hamper the productivity of land.
5. Safety Measure for any leakage of
gas which will affect the local people
Proper safety measure are in build in design and proper operation and maintenance no anticipated gas leakage is predicted. But still during O&M proper safety measure to control any leakage will be taken care of.

B. Grievance Redressal Mechanisms
95. A District Level Project Steering Committee (DLPSC) headed by the Concerned District Commissioner (DC) has been established under the NKUSIP project vide GO: No N. A. E. 45 PRJ 04 dated 18/06/04 for 21 towns, in addition to the functions of the committee, Grievance redress was included as additional function vide GO: No N. A. E. 167 PRJ 05 dated 22/09/05 for the same towns and for the additional four towns of Yadgir, Nipanni, Illkal & Sindhanur which were included later the DLPSC was established along the function of grievance redress vide Go No N. A. E124 PRJ 2007, dated 29/11/07, hence a grievance redress mechanism is in place for the project. 96. A Grievance Redressal Committee (GRC) is formed to ensure that grievances are addressed in a timely manner, facilitating timely project implementation. The GRC will comprise representatives from APs (ensuring representation of vulnerable households), local government/Yadgir ULB, Investment Program Officials – Deputy Project Director of NKUSIP, and NGOs/ community based organizations (CBOs). The GRC redresses grievances at the local-level in a consultative manner and with the participation of the affected households, or their representatives. GRC meetings will be convened as necessary to address complaints as they arise. The time and date of GRC meetings will be announced to APs by the implementing NGO and RO a week in advance. The Process of Grievances Redressal Mechanism is as follows:
37
IX. ENVIRONMENTAL MANAGEMENT PLAN
A. Overview:
97. In order to address the impacts predicted in the earlier sections, mitigation measures are discussed in this section and an Environmental Management Plan (EMP) is recommended. EMP also identifies the role of various agencies in the implementation of these measures. 98. No major environmental or social issues are anticipated due to the implementation of the proposed waste water works. The critical issues will however be to minimise air and noise quality impacts during the execution of this project. 99. While, the impacts are not very severe and permanent, care has to be taken to ensure that the ambient environmental conditions do not deteriorate. The project on the whole will improve the health and sanitary conditions, water portability and drainage system of the project area.

X. FINDINGS AND RECOMMENDATIONS
A. Prioritization based on Environmental Issues
100. The present study is an attempt to highlight important environmental considerations undertaken in study of construction of new sewage system under NKUSIP and use finding from this study to determine the nature and focus under the IEE. 101. Environmental indicators are developed based on the severity of negative impacts produced by the sewage improvement program. An indicator so selected has been assigned depending upon the nature and severity of externalities
Environmental Screening Matrix / Results for Sewerage Work 102. A matrix of environmental impacts, as shown below in Table: 23 was developed from examination of potential environmental impacts and mitigation measures discussed in earlier Sections

103. As evidenced from the above matrix, the project is not expected to cause any irreversible impact on the area. However, most of the environmental impacts that are likely will occur for a short period of time during construction phase. The project upon completion would realize several positive impacts, most significant of which being the improved environmental quality and centralized waste water system.

(i) The Environmental ManagementPlan (EMP) along with monitoring plan should be ensured for proper implementation from contractor.
(ii) Since the city does not have any sewerage system, the CMC should take appropriate action for commissioning of 11.00 MLD STP to promptly solve the unsanitary conditions prevailing in the city.
(iii) It may be emphasized that, owning to : (i) scale of activity, (ii) location of the proposed sub-project component, and (iii) ‗no environmental sensitivity‘ of the
(iv) sub-project town, none of the components required to go through the process of EIA. It may be emphasized that the present IEE, which identifies potential impacts and suggests appropriate mitigation measures, is sufficient enough to safeguard the environment. There are no significant adverse impacts, which are irreversible or may lead to considerable loss/destruction of environment, envisaged. All the impacts are simple and moreover proven mitigation measures exists to minimize/mitigate the same. Hence, no further study such as an EIA is required.

Could changes in temperature, precipitation, or extreme
events patterns over the Project lifespan affect technical or
financial sustainability (e.g., increased extreme rainfall
increases flooding, damaging proposed infrastructure)?
Are there any demographic or socio-economic aspects of the
Project area that are already vulnerable (e.g., high incidence
of marginalized populations, rural-urban migrants, illegal
settlements, ethnic minorities, women or children)?
Proposed project will not impact any
marginalized population, rural-urban migrants,
illegal settlement, etc.
Could the Project potentially increase the climate or disaster
vulnerability of the surrounding area (e.g., by paving
vulnerable groundwater recharge areas, or using water from
a vulnerable source that is relied upon by many user groups,
or encouraging settlement in earthquake zones)?
