2.1 Need for the project

Proposed command areas Taluks are severely prone to erratic droughts due to lack of south-west monsoons. Drought causes agriculture a risky venture. Due to which people are constantly translocating to adjoining towns and cities. The people of the region have no other employment opportunities except agriculture and there is potential land bank to grow suitable crops in the region. Hence providing irrigation and stabilizing the agricultural production, provides a much needed relief to the people. It improves the per capita income and standard of living of the people. Further it utilizes the water and land resources and substantially improves GDP contribution from agriculture.

The cultivable area of Chadchan village, part of Havinal, Shiradona and other surrounding villages are left out and not getting irrigation water from any of the UKP schemes. These villages fall under Indi taluk of Vijayapura district located in the border of Karnataka and Maharashtra. The lands of these villages are almost at the tail end of Indi Branch Canal. Length of Indi Branch Canal is 172.0 Km and these villages are located at about Ch.168.0 Km.

Initially, as per the Master plan, these villages were proposed to be provided with Irrigation facility from either Indi Branch Canal or Indi Lift Canal. After detailed survey of Indi Branch Canal with designed bed fall these areas were left out as they were low lying elevation. The elevation of these villages is between RL 485.0 to RL 460.0 and bed level of Indi Branch Canal is RL 446.0. The distance from Km 168.0 of IBC to left out area is about 6.0 Km.

Alternatively, the areas of these villages are below the bed level of Indi Lift Canal but due to having achieved contemplated command area, the canal is terminated near Zalki before crossing NH-13. The distance from tail end of Indi Lift Canal to Chadchan area is about 15.0 Km.

The area being near to Bhima River and drought affected, does not receive water from any of the schemes planned under Upper Krishna Project. Farmers of this area and local leaders are pressing hard to provide Irrigation facility to this suffering command area.

2.2 Re-allocation of water for the proposed scheme

It is found that under Indi Branch Canal, the contemplated ICA of 1,31,260 Ha is not achieved physically. The notified command area of IBC as on date is 1,24,109 Ha and there is no scope for further extension of command area under IBC as the canal is tailed off at Maharashtra border. Hence there is a balance of 7150.0 Ha of command area under IBC.

Considering the cropping pattern of IBC (UKP Stage-II), there will be a savings of 47.146 MCM or 1.665 TMC of water under IBC. This balance area along with the left out areas of Chadchan and surrounding villages (2065 ha) are considered for providing irrigation facilities under the present project.

It is not possible to irrigate 9215.0 Ha out of savings of 1.665 TMC from Indi Branch Canal, by adopting the above cropping pattern. Hence, Annual water requirement for the proposed scheme is works out to be 49.305 MCM or 1.741 TMC.

On study of topography of the command area it is found that after delivery chambers the command area is in falling contour and both the branch canals runs in ridge line with several drops. It is proposed to make use of this available natural head and provide the distribution system with closed conduit. This will increase the overall efficiency of project from 51% to 75%. Hence there will be reduction in requirement of water and the water requirement for the proposed scheme will be 33.41 MCM or 1.18 TMC. However, remaining 0.56 TMC of water will be utilised at later stages of the project either for tank filling to recharge the ground water or to supply the drinking water. Hence, the water allocation for the scheme is within the award of KWDT.

2.3 Command area of the project

The command area of 9,215 ha is spread across Indi Taluk of Vijaypura District. 8 villages will be benefitted under this scheme and they are as follows.

3. Description of baseline environment

Collecting the baseline environmental status of the project area helps to ascertain the magnitude of impacts that are likely to be caused due to the proposed project on different environmental components. It also helps to identify critical environmental attributes required to be monitored during and after the proposed development. To assess the baseline environmental status, command area, 10 Km radius from the main project components were considered and the data was collected during the period Monsoon (July 2016 – September 2016). In addition to the baseline environmental monitoring, field inspection in the study area, collection of secondary information for all the environmental components and discussions with the officials and local public were conducted by the experts to establish realistic information on the area with respect to the project.

3.1 Physical Environment

3.1.1 Climate & Meteorology

Air borne pollutants is dispersed by atmospheric motion. Knowledge of these motions, which range in scale from turbulent diffusion to long-range transport by weather systems, is essential to simulate such dispersion and quality of impacts of air pollution on the environment. The purpose of EIA is to determine whether concentrations are likely to encounter at fixed locations (known as the receptor), due to the given sources (locations and rates of emission known) under idealized atmospheric conditions.

Secondary information with respect to meteorological data (Temperature, Relative Humidity, Rainfall, Wind speed and Wind direction etc.) were collected from Vijayapura and Bagalkot meteorological observatory.

3.1.2 Ambient air quality

According to preliminary investigations, the ambient air quality in the study area is found to be good, in the absence of industrial growth in the command area. However, as part of the baseline data collection and in order to understand the status of ambient air quality during the study area, 2 ambient air quality monitoring stations were established and continuously monitored during the study period. AAQM was carried out on 24hrly basis on weekly twice mode continuously for one single month in Monsoon season (July 2016 – September 2016).

The results of ambient air quality reveal that, PM10 was in the range between 56.58 – 62.72g/m3,

PM2.5 was in the range between 20.86 -22.86g/m3. SO2 and NO2 are in the range between 3.67 –

3.81g/m3 and 10.34 – 11.19g/m3 respectively. Whereas NH3 ranged between 14.89 –

14.91g/m3, CO and O3 were 0.82 – 0.84g/m3 and 1.38 -1.51g/m3 respectively. The air quality index in the study area is found to be satisfactory for PM10 and for PM2.5, NO2, SO2, NH3, CO and O3 it was found to be good. Benzene, Benzo(a) Pyrene and all heavy metals were found to be BDL.

3.1.3 Ambient Noise levels

The results of ambient noise levels were compared with Residential standards and results reveal that, the noise levels in the study area ranging from 43.97 – 47.8 dB (A) for day time and 36.53 – 38.81 dB (A) for night time during Monsoon season. Overall, the noise levels in all the seasons



were observed to be within the CPCB standards. Overall, the noise levels in the seasons were observed to be well within the CPCB standards.

3.1.4 Geology and Minerals

The main rock type observed in the command area is Basalt belonging to Deccan Traps of various flows belonging to Upper Cretaceous to Lower Eocene Age. Geology map is given below.

3.1.5 Soil characteristics

Geographically, the district lies in the tract of the Deccan Plateau. The upland soil being shallow, the villagers are generally confined to the banks of the streams and are far away from one another. The Bhima Valley has plains and consists of rich tracts of deep black soil stretching from west to east.

Deep to very deep black soils (Vertisols) - more than 90cm depth

Medium Black soils (Vertisols and inceptisols) - 22.5 cm to 90 cm depth

Red sandy loam - (22.5 cm to 90cm depth)

Shallow heavy or fine textured.

3.1.6 Hydrology

Bhima River forms Northern boundary with the Maharashtra State. Southern part of the Vijayapura District forms a catchment area of the Krishna while northern part of the catchment area of Bhima. Bhima River is an important tributary of Krishna River. A Major Dam has been constructed across the Krishna River near Almatti in the district. Don River is the tributary of the Krishna River and flows for about 160 Kms in a meandering course from west to east in the central part of the District. The water of this river is generally brackish. Drainage pattern is sub - dendritic to sub-parallel in nature and the drainage density varies from 0.49 to 1.02 Km/ Sq.Km. Average rainfall of the district is 578 mm. Climate varies from 20° C to 42.0°C.

3.1.7 Surface Water

The surface water quality analysis results reveal that, Conductivity and Total Hardness of the samples varied from 550 µs /cm at Lift Point near Holisankh -1073 µs /cm at Bori River and 164 mg/L at Downstream of Lift Point -368 mg/L at Bori River respectively. BOD of surface water ranges from 6 mg/L at Upstream of Lift Point -14 mg/L at Downstream of Lift Point. Sulphate and Chloride results varied from 57.8 mg/L at Doddahalla - 94.3 mg/L at Bori River and 43.9 mg/L at Upstream of Lift Point -131.9 mg/L at Bori River respectively. Total coliform was detected in all locations except Doddahalla. E.coli was detected in downstream area of lift point. Overall, the physic-chemical parameters of the surface water were found to be within the standards except for the Total Coliform and E.coli content in certain samples.

3.1.8 Ground Water

The Physico-chemical parameters for the Ground Water are within the standards. Conductivity values were found to be 1273 µs /cm at Chadchan Village and 1642 µs /cm at Bardol Village. Total Hardness detected was 508 mg/L and 532 mg/L at Chadchan Village and Bardol Village respectively. Sulphate values were found to be 181.6 mg/L and 177.4 mg/L at Chadchan Village and Bardol Village respectively. Total coliform and E. coli were absent in the ground water samples collected.

No rare, endangered and threatened species found in the region.

4. Anticipated Environmental Impacts & Mitigation Measures

Due to the activities of the project, there will be potential impacts on the environment of varying magnitude. Most of the impacts are likely to occur during the construction phase of the project. The following sections reveal the impacts due to the project on the physical, biological and social environment. Impacts have been assessed based on the information collected from the screening and feasibility study reports, field surveys and additional secondary data collected as part of the study. The majority of the impacts are confined only during the construction stage.



4.1 Ambient Air Quality

The construction of the project is expected to last approximately in 24 months. The initial site clearing will be followed by site preparation activities

Sources of air pollution

Pollution due to fuel combustion in equipments: The operation of construction equipments requires combustion fuel. Normally, diesel is used for such equipments. The major pollutant which gets emitted as a result of combustion of diesel is CO & HC.

Dust pollution: The operation of the trucks carrying construction materials to the site, batching plants during the construction phase is likely to generate fugitive emissions, which can move even up to 100 m in predominant wind direction.

Emissions due to usage of firewood for cooking at labor camps.

Due to operation of DG sets and excavation, laborers are prone to health problems.

The following mitigation measures will be followed to control potential emissions of fugitive dust during construction of the project:

High speed diesel (HSD) with low sulphur content will be used for the construction equipments/ vehicles which has low ash content.

Unpaved roads in the project construction site are watered frequently as necessary to prevent fugitive dust. All vehicles carrying construction materials are covered with tarpaulin to avoid spillage of construction materials. Regular water sprinkling will be undertaken (3 times a day) to avoid fugitive dust emissions.

All the trucks carrying construction materials to the site shall be inspected regularly and shall have valid Pollution under Control (PUC) certificate.

Labours camps shall be provided with LPG facilities.

Usage of PPEs like nose masks will be provided for construction labours.

4.2 Ambient Noise Level

During construction phase, various sources of noise pollution arise due to operation of machineries like concrete plant, cranes, batch plants, Crane, Generator, Tractor, Welder/Torch, Vibrating Hopper etc.,

Other source of noise pollution includes movement of vehicles for unloading of construction materials, fabrication, handling of equipments.

Construction activities are expected to produce noise levels in the range of 80 – 95 dB (A).

Various measures proposed in spite of noise levels are lower than the prescribed standard values as per CPCB, are presented below.

DG sets are placed on the rubber cushion padding, enclosed and maintained well in good condition. It is encased and barricaded & taken to all places where it will be used. This reduces the noise level in and around the source by 4 dB.

Construction activities shall be restricted only to day time and there should not be any construction during evening and night hours to avoid the psychological effects on surrounding population and biota.

During construction time, possible chances of number of trucks coming to the project area is more carrying debris, muck etc and the drivers of these vehicles must be instructed with sign boards and not to use shrill horns for any purpose.

Controlled blasting will be undertaken wherever necessary to minimize the noise even though it is cost effective.

PPEs such as, ear plugs and ear muffs will be provided to the workers.



Periodic maintenance and servicing of construction equipments/ vehicles.

Acoustic enclosures will be provided for DG sets

4.3 Water Environment

The quality of water resources both surface and ground water may also deteriorate if solid waste management practices are not adopted in the labour camps of the project during peak construction phase.

Improper treatment of sewage from labor camps leads to infiltration into the subsurface soil and finally affects the ground water of the region. This will create unaesthetic conditions in the site, attracts mosquitoes/flies, thereby chances of deteriorating the health of the workers in unhygienic conditions. Improper disposal of construction debris, used oil, diesel for DG sets, etc will result in ground water contamination and in turn affecting drainage of the area.

The mitigation measures include;

The sewage generated from the labour camps shall be treated in the Septic Tank and Soak Pits designed and constructed as per IS 2470 Part-I & Part-II.

There will be no open discharge of sewage from labour camps and the labour camps will be provided with sufficient bathrooms and toilets. Periodical health check-ups for labors will be done.

Construction debris will be reused at site, used oil generated from the DG sets will be stored separately and handed over to KSPCB authorized recyclers.

During construction of intake canal, the river course and the point of contact of intake canal will be provided with sand bags

4.4 Biological Environment

During construction, due to the fugitive dust, photosynthetic activity would be reduced and leads of wilting of plants.

Use of river water for domestic needs by labors will bear riverine water pollution and affects aquatic biota.

Use of fire wood for labor camps results in cutting of trees.

Construction equipment / vehicles washing leads to oil spillages into river and leads to reduction in dissolved oxygen levels.

Improper disposal of construction materials and domestic wastes leads eutrophication.

Mitigation measures:

Periodical water sprinkling in and around the construction areas including access roads to avoid fugitive dust generation.

Labor camps shall be located 1 Km away from the river course and imposing restrictions for not using the river water for domestic purpose.

Labors camps shall be provided with LPG facilities.

Construction equipment / vehicles washing shall be undertaken at authorized service stations.

Security personnel near river course and sign boards will be erected to educate the labors.

4.6 Evaluation Impacts

Matrix method was used to identify interactions between various project activities and environmental parameters and components. Later, a weightage of 1-10 shall be given to the impacts based on the significance of the impacts. The impacts are quantified „with‟ and „without‟ EMP. The criteria adopted for weightage are given below;

Chadchan lift irrigation scheme in Executive summary Vijayapura, Karnataka of Draft EIA report


5. Analysis of Alternatives

The cultivable area of Chadchan village, part of Havinal, Shiradona and other surrounding villages are left out and not getting irrigation water from UKP scheme.

These villages fall under Indi taluk of Vijayapura district located in the border of Karnataka and Maharashtra. The lands of these villages are almost at the tail end of Indi Branch Canal.

Length of Indi Branch Canal is 172.0 km and these villages are located at about Ch 168.0 km. Initially, as per the Master plan, these villages are proposed to be provided with Irrigation facility from either Indi Branch Canal or Indi Lift Canal.

After detailed survey of Indi Branch Canal with designed bed fall these area were left out due to higher elevation. The elevation of these villages is between RL 485.0 to RL 460.0 and bed level of Indi Branch Canal is RL 446.0.

The distance from km 168.0 of IBC to this left out area is about 6.0km. Alternatively, the areas of these villages are below the bed level of Indi Lift Canal but due to having achieved contemplated command area, the canal is terminated near Zalki before crossing NH-13.

The distance from tail end of Indi Lift Canal to Chadchan area is about 15.0 km. The area being near to Bhima River and drought affected do not receive water from any of the schemes planned under Upper Krishna Project.

Therefore, Chadchan LIS is proposed to irrigate 9215 Ha of dry land by utilizing 1.2 TMC of water.

6. Environmental Monitoring Program

The purpose of the monitoring program is to ensure that the objectives of the project is achieved through the mitigation measures and result in desired benefits to environment and local population of the region.

7. Social Impact Assessment

Chadchan Lift Irrigation Scheme is proposed to irrigate an area of 9,215Ha by lifting 1.20 T.M.C of water from Bhima River during Khariff and Rabi season. The project aims at providing irrigation facility to 8 villages of Indi taluk. Benefiting villages include Chadchan, Havinahala, Godihala, Halahalli, Baradol, Shiradona, Revatagoan and Neevaragi.

7.1 Demographic profile of the villages

The total population of the eight villages is 40871. Out of which, 21017 is male and 19854 is female.

Total 40871 21017 19854

7.2 Impact of the project

During the project construction phase and operation-management phase additional employment will be generated.

The only negative impact is that 288 acres of agricultural land spreading across 8 villages will be lost for the project construction purposes and they will be sufficiently compensated as per rules. Since no residential or commercial properties affected, there is no need for any displacement and hence resettlement /rehabilitation is not involved.

Villagers have some additional demands for construction of linking roads, sanitation facilities etc which will also be duly attended by the Govt., especially since this backward villages are in the hit list for the developmental interventions.

So overall impact of the project is positive which will bring long term development/ growth in the development map of these villages.



8. Project Benefits

The CLIS is proposed to provide economically viable and socially acceptable irrigation practices for the command area. Irrigation is important to the health of the agricultural industry. Improving the viability of individual farming and increasing the efficiency and economic stability of the command area taluks and also contributing to the economic and social objectives of the Karnataka State are the expected outcomes of the proposed scheme. Some of the important project benefits are given below:

Agricultural linkages will be considerably improved.

The project improves total farm output and hence raises farm income.

Project improves yields through reduced crop loss due to erratic, unreliable or insufficient rainfall. The details before and after the advent of irrigation is given below.

It allows a greater area of land to be used for crops in areas where rain fed production is impossible or marginal. Due to the implementation of the scheme 9215 Ha will be under irrigation.

Extensive agricultural production supplies raw materials to the nearby small scale industries thereby increasing the economy in the region.

Altogether, population of 40,871 belongs to 7945 families in the command area will be benefitted directly under the scheme.

Direct employment opportunities for 150 members during construction phase and 30 members during operation phase of the project. Further, indirectly labor opportunities will be substantially improved since larger area will be brought under irrigation.

It improves fodder crops and in turn dairy farming in the command area.

Increased benefits of water conservation through closed conduit irrigation for the entire 9215 Ha of command area.

The project requires only 108.4 Ha for implementation of the scheme and does not envisage rehabilitation and resettlement.

No tree cutting involved and no forest land required for implementation of the scheme. Agro forestry shall be taken up in command area and it improves the ecosystem services.

9. Environmental Management Plan

Although agriculture is usually associated with its positive impacts on human life, irrigation practices may be associated with impacts on environmental conditions, which may eventually curtail the sustainability of irrigation projects. For this reason, Environmental Impact Assessment (EIA) has been recognized as an integral part of the early planning studies of irrigation projects in order to identify any expected negative impacts and suggest the necessary mitigation plans to curb these impacts through formation of Environmental Management Plan (EMP).

9.1 Command Area Development Plan

9.1.1 Catchment Area Treatment (CAT) plan

Karnataka is a pioneer in implementing watershed program since 1983.Dry land development boards were constituted at in the divisional level, model watersheds, district level macro watershed programs, DPAP, DDP, IWDP, WGDP, RVP, NWDPRA and more recently from April 2008 Integrated Watershed Development program (IWMP).A state level perspective and Strategic Plan (SPSP) is prepared for the state and entire area (120.85 lakh ha) is contemplated to be treated by the end of XIV the plan period, on 90:10 ratio between center and state. Further, all programs aimed at enhancing irrigation use efficiency are brought under PMKSY to provide her kheth KO Pani and to increase crop yield per drop of water. As a result all the watershed programs are implemented under this activity.

In the district of Vijayapura, soil and moisture conservation program are being implemented since 1970s and some of the areas are revisited to take up post bund maintenance and similar activities. Desert Development program is implemented to saturate the rain fed areas for sustainable crop production activities.

Some of the methods suggested for soil conservation for CLIS catchment area are given below.

1. Broad based contour bunding on slopes (1-8%)

Outward cross slope of 1-8%

Longitudinal slope of 8%

Length of terrace, 20-35 m

Width of terrace, 3 to 5.5 m

2. Riser (earthen or stone)

Steep batters of, 0.25:1 3 Earthen shoulder bund

0.5 m base, 0.3 m height,01 m top

3. Stone bunding or fencing when stone is easily available.

0.3 m base, 0.2 m height, 0.1 m top

Followed by earthen bund of 0.1 m top

4. Land leveling

Low (bottom) flat deep areas leveled.

Bench terraces are also leveled by cut and fill.

5. Land slide control

Vegetative means

6.Goole

Water channels conveying water from natural springs as well as rainwater.

Same design delivers 5-50 liters/min in winter and 100-500 liters/min during rainy season.

Needs improvement in regulation.

7.Khatta/khala

Earthen ponds collecting discharge water of & seepage water.



9.1.1.1 Cost Estimates as per Soil conservation treatments suggested

Area to Treated (ha) – 9210 ha

No. of Check dams (ha) – 35

Cost (Rs. Lakhs) – 175

Plantations (ha) – 9215

Cost (Rs. Lakh) – 297

9.1.2 Water Users’ Association (WUA)

The modern irrigation management aims at high efficiency of water conveyance and appropriate methods of water application, through participatory irrigation management at each stage of irrigation development. In Karnataka, it is essential to promote and implement the theme of participatory irrigation management in all the Irrigation projects through formation of Water Users‟ Association. The construction of OFD works will be taken up after formation of WUAs under the supervision of CADA, Belgaum.

The efficient management of irrigation water for maximizing productivity requires, firstly the efficient on farm water management and secondly the optimization of the use of water and land, through appropriate methods of water application. The efficient on-farm water management is related to water delivery system and allied works in the command area, which distributes the water to each farm. The items of works pertaining to on farm water management are termed as “On Farm Development Works”.

The On Farm Development works comprise of the following,

Maintenance of disnets, sumps

Control structures

Maintenance of Automation

Surface Drainage system

Farm roads

Land forming (Smoothening / grading/leveling)

9.1.2.1 Green belt development plan

9.1.2.1.1 Plantation around intake canal and jack well cum pump house

Green belt development activities will be taken up on either side of the intake canal and in and around jack well cum pump house along with canal bank plantation.

9.1.2.1.2 Agro forestry activates in command area

Agro-forestry refers to the practice of Agriculture and Forestry in the same piece of land. The Karnataka Forest Department (KFD) has accorded high emphasis on farm forestry as a component in the afforestation program. The sector of Agro-forestry or Farm Forestry has a good potential as most of the agriculture lands are devoid of any trees, in the district. The trees if planted on the bunds and on the boundary of the lands protect the crops from the desiccating high winds and also provide additional income from the trees to the farmer apart from providing him fodder and fuel as well.

Silvi-Pasture refers to the planting of the trees in a predominately grassland so as to provide fodder all the year round. This afforestation is aimed at not only addition of tree species, but also addition of highly nutritive and palatable grass species in the area, thereby providing much needed nutritious fodder to the livestock population.
