1. Introduction

The expansion proposal involves expansion of command area from 42,500 ha to 52,700 ha with

an additional water allocation of 2.473 TMC of water (totaling to 6.273 TMC) benefitting 31

more villages. Total land requirement is about 2419 ha. About 0.73 ha of forest land is involved.

An intake channel for a length of 2.0 km is proposed to draw 6.273 TMC of water to irrigate

52,700 ha. The Government of Karnataka vide GO No. WRD-20 KBN-2016 dated 31.08.2017

accorded revised administrative approval for the project. The estimated project cost is about Rs.

3572 Crores.

2. Project Description

The proposed lift irrigation scheme near Kavatagi village requires 6.273 TMC of water from River

Krishna to provide irrigation facilities to an area of 52,700 Ha. It is proposed to lift water near

Old Kavatagi village in Jamakhandi taluk of Bagalkot Dist. The intake structure is located on fore

shore of Almatti Reservoir. There will be sufficient water available from 15th June to October

15th (Khariff Season). Hence no separate arrangement is required for impounding water for

lifting. Water allocation for Almatti Reservoir will not be affected. The report is prepared

considering the present allocation of 3.8 TMC and the additional allocation of 2.5 TMC to

provide irrigation to 52,700 Ha through flow irrigation by Gravity canal.

2.1 Need for the project

The project was accorded Environmental Clearance by the Ministry of Environment, Forest and

Climate Change, New Delhi on 31.07.2017 to irrigate 42, 000 ha of command area by utilizing 3.8

TMC of water from Krishna River to benefit 36 villages of Vijayapura, Bagalkot and Belagavi

Districts. Copy of Environmental Clearance enclosed as Annexure-1. The project invoves diversion

of 0.73 ha of forest land for which stage-I Forest Clearance has been accorded by the Ministry on

15.06.2017.

The expansion proposal of Tubachi-Bableshwara Lift Irrigation Scheme involves expansion of

command area from 42,500 ha to 52,700 ha with an additional water allocation of 2.473 TMC of

water (totaling to 6.273 TMC) benefitting 31 more villages. The present proposed expansion

project falls under 1(c) of schedule of EIA Notification, 2006. The command area of the project is

>50,000 Ha and therefore according to EIA Notification, 2006 and its subsequent amendments in

2018, the proposed project is categorized as 'A' and requires Environmental Clearance from

MOEF&CC, New Delhi. The Terms of reference (ToRs) for the project was accorded by the

MoEF&CC vide letter No. J-12011/5/2015-IA-I(R) on 29.11.2017.

2.2 Water availability

The catchment area of river Krishna at Vijayawada gauge site is 2,51,360 Sq.km. Earlier the Yield

Series was built up by considering the Flow series at Vijayawada from 1894 to 1972 as agreed to

by the Party States before the Krishna Water Disputes Tribunal which determined that for the

purpose of the case of the Krishna Water Dispute, the 75% dependable flow of river Krishna upto

Vijayawada is 58339.2 Mcum (2060 TMC). The yield as adopted in the KWDT-II which is

reproduced has been the basis for working out the yield at Almatti and Narayanpur dams.

2.3 Command area of the project

The expansion proposal of Tubachi-Bableshwara Lift Irrigation Scheme involves expansion of

command area from 42,500 ha to 52,700 ha with an additional water allocation of 2.473 TMC of

water (totaling to 6.273 TMC) benefitting 31 more villages.

that, the noise levels in the study area ranging from 46.5-49.6 dB (A) for day time and 36.12–38.84

dB(A) for night time during Monsoon. In post – monsoon season, values ranged from 41.92 –

44.16 dB (A) for day time and 35.66 – 36.12 dB (A) for night time. Values were found to be 42.24

– 43.38 dB (A) for day and 34.88 – 37.22 dB (A) for night during pre-monsoon season. Whereas,

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

3.1.4 Seismicity

The Karnataka state is categorized as moderate to low seismic risk zone. The following Districts

are falling in Zone III (Moderate Damage Risk Zone (MSK VII) viz., Bidar, Gulbarga, Vijayapura,

Bagalkot, Belgaum, Dharwad, Uttar kannada, Shimoga, Udupi, Dakshina Kannada, Kodagu. All

other Districts are falling under Zone II( Low Damage Risk zone MSK VI).Even though the parts of

Belgaum, Vijayapura and Bagalkot district area under Zone -III, the proposed lift location and

command area falls in 'low damage risk zone'. Hence, chances of earthquakes are very less.

3.1.5 Geology and Minerals

Study area is comprises two simple ‘ahoea’ flows and is occurring between 530 m to 618 m above

msl. Each flow is characterized by a meter thick basal klinkery horizon, a middle massive part, and

a fragmentary or brecciated zone at the top.

Road Metal and few dimensional Colored Granite are reported in the District. Laterite occurrences

were observed during the field traverses which are not being exploited due to sporadic

occurrence.

3.1.6 Soil characteristics

In the study area the soil types found in the command area are predominantly shallow to deep

black, moderately well drained, clay soils with slow permeability. Vertisol, Entisol and Incept sols

are found in the proposed command. The black cotton soil is rich in bases (alkaline condition) and

has a very high water holding capacity. Major area is covered by black, clay soils constitute

roughly 95 percent, and are shallow to moderately deep (22.5 to 90 cm), clayey, with 45 to 55 per

cent clay and contain free calcium carbonate throughout the profile. There is generally a zone of

calcium nodules and gypsum in the soil profile at a depth of 45 to 90 cm, the principal salt being

gypsum. Below the gypsum layer disintegrated impermeable murrum layer exists, the internal

drainage of the soil is lateral rather than vertical within the profile.

3.1.7 Hydrology

The study area and its environs are underlain with Basalt. This hard rock is devoid of primary

porosity. However, weathering, Fissures / Fractures, joints and fault zones act as conduits for

movement and storage of groundwater and yield water in abstraction structures. Groundwater

occurs under phreatic conditions in weathered zone and undersemi-confined to confined

conditions in jointed and fractured formations of hard rocks. Surface water occurrence is

negligible and tanks were observed to be dry during pre-monsoon period.

The study area forms a part of Vijayapura district which is a part of Krishna River Catchment /

Basin. Gujganj Halla, Dhukarwadi Nala and Yargatti Halla and their small tributaries and Bor River

and Don River are the other major tributaries of River Krishna in the study area. Most of these are

seasonal rivers which drain in to River Krishna.



15

3.1.8 Surface Water

In the entire study area 3 surface water samples were collected in each season, totaling to 9 SW

samples (for three seasons), of which all the three samples collected in post monsoon conforms to

class ‘C’ which is represented as Drinking water source with conventional treatment followed by

disinfection, three samples collected in pre monsoon conforms to ‘D’ which is fit for Propagation

of wildlife, fishes and the three samples collected in the monsoon season falls in category ‘E’

which is fit for irrigation, industrial, cooling controlled waste disposal.

3.1.9 Ground Water

The ground water quality analysis results for post monsoon season (Dec, 2017 – Feb, 2018)

revealed that, the Total Hardness ranged from 272 mg/L near Takkalaki village to 1040 mg/L near

Kanamadi village, Electrical Conductivity was 33.73 µs /cm in Kanamadi village to 1025 µs /cm

near Takkalaki village. Total Coliform was <1.8 MPN/100 mL.

During Pre – Monsoon season (March – May 2018) Total Hardness ranged from 216 mg/L near

Takkalaki village to 996 mg/L near Kanamadi village, Electrical Conductivity was 1016 µs /cm in

Takkalaki village to 5620 µs /cm near Kanamadi village. Total Coliform was <1.8 MPN/100 mL.

During Monsoon season (June – August 2018) Total Hardness ranged from 428 mg/L near

Takkalaki village to 1372 mg/L near Kanamadi village, Electrical Conductivity was 1672 µs /cm in

Takkalaki village to 4407 µs /cm near Kanamadi village. Overall, the groundwater quality results

were compared with IS 10500:2012 (second revision) in all the seasons and the results were

observed to be well within the standards.

3.2 Biological Environment

3.2.1 Flora and Fauna

The study area supports wide range of floral, avifaunal and mega faunal species as it

predominantly involves agricultural, Horticulture, Plantation and Forest landscapes. Horticulture

crops like Pomegranate, Grapes and Mango are grown in most of the study area. River Krishna in

its bank supports a wide range of Avifaunal and faunal diversity.

A total of 13 tree species were recorded during the study. In addition to this, 65 species of herbs,

30 species of shrubs and 11 species of climbers were recorded during Post Monsoon season. A

total of 69 species of herbs, 30 species of shrubs and 13 species of climbers were recorded during

Pre Monsoon season. Similarly, 75 species of herbs, 30 species of shrubs and 14 species of

climbers were recorded during Monsoon season. All the species recorded were common to the

region and no RET species were observed during the study. Family Poaceae, Fabaceae and

Cucurbitaceae are the dominant families in Herbs, Shrubs and Climbers respectively.

Similarly, a total of 40 avifaunal species and 22 butterfly species were recorded during Post

monsoon season, 43 avifaunal species and 20 butterfly species were recorded during Pre

monsoon season and 31 avifaunal species and 16 butterfly species were recorded during the

Monsoon season. All the recorded avifaunal species belonging to Least Concerned category as per

IUCN conservation status 2018. Indian peafowl is the only avifaunal species belonging to Schedule

I of Wildlife (Protection) Act, 1972. Common Crow is the only Butterfly species belonging to

Schedule IV of Wildlife (Protection) Act, 1972. All other species are common to region.

Many local people and shepherds expressed that mega faunal species such as, Cobra, Common

Indian Hare, Wild boar; Bengal Fox, Porcupine, etc are the commonly found species in the study

area. Indian Fan throated Lizard and Monitor Lizard ate the two reptile species found during the

inventory. Common Indian Monitor, Indian cobra, Bonnet macaque, Jungle Cat and Bengal Fox

belongs to Schedule-II of Wildlife (Protection) Act, 1972 respectively. As per IUCN Conservation

status-2018 all the recorded species least concerned to the region.

3.2.2 Protected Areas

No rare, threatened, endangered plant or animal species are found in the region as there are no

protected areas or ecologically sensitive areas within 10 Km radius from the proposed project

components.

3.2.3 Aquatic Ecology

Detailed Physico-chemical and Biological studies carried-out in the river Krishna, in and around

the project site, presents ‘optimum’ features to support/sustain varieties of aquatic life present.

The river is found to be ‘free’ from pollution threat.



17

The Plankton community, Phyto- and the Zooplankton constituents, in effect, presented ‘low’

status, by diversity and numerical density. However, scores of planktivores fish species recorded

subsists on the food available presently which, during the prime season (monsoon and thereafter)

is likely to improve for the resident and migrating fish germplasm. The littoral fauna also were in

‘low’ concentrations, constituted by Insects and Molluscs: the latter group had a fairly good

representation by Castrapods and Bivalves and members belonging to the Crustacean group.

Fish species constituted by Carps and Predatory fish species presented a ‘poor’ picture – could be

on account of the low-level of water in the river and on-set of lean season when even the fishing

activity was quite minimal, as reported. The Immigrant African Catfish ,Clarias gariepinus, recorded

in the upper reaches may migrate to other parts of the said lotic water body, may establishes

itself dominating the fishery as a whole. The situation is quite alarming which calls for initiating

concrete steps for its total elimination from the area/river as such.

Fish stocking and its augmentation has been highlighted which should be taken-up with all

sincerity and seriousness in order to enhance the fish production to facilitate scores of local and

migratory fishermen to ekk-out their livelihood.

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 section reveals the prediction of impacts due to the project on the physical,

biological and social environment. Impacts have been assessed based on the information collected

from the primary and secondary data.

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.

• 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.



18

• Emissions due to usage 1

• Due to operation of DG sets and excavation labours are prone to health

problems.

of firewood for cooking at labor camps.

• Fugitive dust emissions during excavation for main canal, branch canals and

distributaries.

Mitigation measures

• HSD with low sulphur content will be used for the DG sets construction

equipments/ vehicles which have low ash content

• Unpaved roads in the project construction site are watered twice a day to

prevent fugitive dust. All vehicles carrying construction materials are covered

with tarpaulin to avoid spillage of construction materials.

• All the trucks carrying construction materials to the site shall be inspected

regularly for having Pollution under Control (PUC) certificate.

• Labors camps shall be provided with LPG facilities (10 LPG Cylinders per

month).

• PPEs like nose masks will be provided.

• During excavation, regular water sprinkling will be undertaken twice a day to

avoid fugitive dust.

4.2 Ambient Noise Level

Sources of noise pollution

• During construction phase, various sources of noise pollution arises due to

operation of Concrete Batching Plant, Crane, Generator, Vibrating Hopper etc.,

this will increase ambient noise levels (75-85 dB (A) and causes discomfort in

residents of Tikota village located at 0.63 km.

• 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).

• Increase noise levels (75-85 dB (A)) will create mental stress in construction

laborers (125) due to continuous exposure to various construction activities.

Mitigation measures

1 https://www.tandfonline.com/doi/pdf/10.1080/00022470.1975.10470150



19

• DG sets will be 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.

• Ear plugs will be provided to all employees and laborers while working,

irrespective of the noise levels as protection, to receive the noise and as well as

exposure of the same for a longer period.

• 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

will be instructed with sign boards and not to uses shrill horns for any purpose.

• Silent Zone boards will be installed at Tikota village where human activities are

there along with proper training to them to handle various equipments, tools

and other related items.

• Supervisory staff will check and monitor to ensure the workers to follow all the

above said measures while at work.

• Controlled blasting will be undertaken wherever necessary to minimize the

noise even though it is cost effective.

• Construction activities will be carried out only between 6 am to 6 pm and

completely suspended during night time.

4.3 Water Environment

Sources of water pollution;

• Improper treatment of sewage from labor camps leads to infiltration into the

subsurface soil and finally affects the quality of ground water. Labors camp is

expected to generate 8 KLD of sewage (considering 75 lpcd for 100 labors)

which is likely to pollute ground water in an area of 1 ha from the source at

60-70 m bgl2

• There will be creation of anaesthetic conditions in the site if sewage is

unscientifically treated thereby, attracts mosquitoes/flies, thus creates chances

of deterioration of health of the workers in unhygienic conditions affecting

productivity at work.

if improperly treated/handled. Further, the source of pollution is

at a distance of 800 m to the Kavatagi village.

• Improper disposal/unscientific handlingof construction debris/muck, used oil

from DG sets will result in ground water contamination through

20

seepage/infiltration factors and in turn affecting the ground water quality of

the area, resulting health concerns of the nearby Kavatagi village on long term.

• Spillage of excavated earth during construction of intake canal leads to

turbidity of Krishna river water, thus leading to siltation at the banks causing

effects on photosynthetic activity of aquatic planktons due to poor sunlight

penetration.

• As the agricultural practices flourish with availability of water, usage of

pesticides and application of fertilizers will naturally increase, thereby the water

quality of Krishna River gets deteriorated due to addition of pesticidal residues

due to natural gradient/drainage and infiltration/seepage factors.

• Improper handling & disposal off excavated earth (39,52,500 cum) and

dumping of muck, boulders into the nearby river affects natural flow regime.

• Improper management towards handling and disposal of domestic solid waste

(35 Kgs/day) from labour camps area & also due to dumping of solid wastes

near river banks leads to pollution of Krishna River causing threat to aquatic

ecosystem due to gradual organic pollution with reduced DO levels.

The mitigation measures include;

• The sewage generated from the labour camps will be treated in the Septic Tank

and Soak Pits designed and constructed as per IS 2470 Part-I & Part-II

guidelines.

• There will be no open discharge of sewage from labour camps and the labour

camps will be provided with sufficient bathrooms (6 No’s) and toilets (10 No’s)

to maintain standards of hygiene. Periodical health check-ups (atleast 6

monthly once) will be conducted for labours.

• Labour camps will be located at 1Km away from the river course and domestic

solid waste from labour camps will be collected in different bins and handed

over to nearby municipal authorities. Further, awareness will be given to

labourers towards avoiding open defection and dumping of solid wastes near

river banks/any water bodies nearby.

• Construction debris will be reused at site; used oil generated from the DG sets

will be stored separately in leak proof drums and will be 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.



21

• The leakages of oil spills from machinery will be be collected in leak proof

containers and then disposed off to KSPCB authorized dealers.

• The recharge to aquifer will be boosted once extensive agriculture is practiced,

a portion of water will be infiltrated into ground recharging the aquifers.

• BOD and COD limits of the water shall be checked regularly as part of EMP to

monitor eutrophication.

• Restrictions on time, method and rate of application of fertilizers and pesticides

shall be imposed to avoid surface run-off and leaching on to the groundwater

regime.

• Artificial recharge of the aquifers by construction of suitable harvesting

structures like farm ponds, nala bunds, check dams and also desilting of tanks.

• Implementing Muck Disposal Plan involving various reuse in construction works

such as inspection path, stabilization of embankment, land levelling helps in

safeguarding the drainage pattern of the area and avoids turbid

condition/siltation of nearby Krishna River/any water bodies.

4.4 Soil Environment

4.4.1 Impacts during construction phase:

• Temporary loss of soil will be envisaged during the construction of temporary

offices, workers camps, stockyards, haul roads, borrow areas etc on fertile areas.

• Leachate generated from the unscientific handling and disposal of solid waste

will create acidification of soil which will possibly affect the nutrient supply to

the plants and increase in soil micro-nutrients toxic for the growth of crops.

• Leakage of used oil from DG sets on the land will impact the soil biota. Oil spill

affects plants negatively by creating conditions which makes essential nutrients

like nitrogen, Oxygen etc needs for plant growth unavailable to them from the

spilled affected soil3

• Movements of heavy machinery will create hard pan thereby affecting crop

growth.

.

• Improper handling of excavated earth while constructing canal line, pump

house, delivery chamber and while lying pipelines etc., will create crop loss.

• Natural drainage will be affected due to excessive soil erosion during

excavation and pipe laying activities.

22

• Improper disposal of excavated earth (39,52,500 cum) will have impact on

agricultural lands affecting productivity.

The mitigation measures include;

• Organic farming related agricultural extension activities will be undertaken with

the support of Agriculture Dept and University of Agricultural sciences., to

ensure optimal use of Fertilizers and Pesticides in the command area in

conjunction with organics.

• Catchment Area Treatment measures will be implemented to reduce soil

erosion and to improve the surface water runoff.

• Restoration of agricultural/open lands utilized as construction site, temporary

offices, workers camps, stockyards will be undertaken soon after the completion

of construction activities.

• Reclamation of salt affected soils and management of saline and sodic soils.

Providing adequate drainage system.

4.5 Impact on Biological Environment

No rare, threatened, endangered plant or animal species are found in the region as there are no

protected areas or ecologically sensitive areas within 10 Km radius from the proposed project

components. The trees situated on the bunds of agricultural plantations and in Government lands

(if any) will be removed with prior approval.

A total 2314.39 Ha area is going to be acquired for the proposed project area, sparse vegetation

observe in study area because of intensive agriculture landscape and involves no forest area.

Hence it can be concluded that there will be no significant impact on the biodiversity of the area.

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;

5. Analysis of Alternatives

The proposed area is deprived of irrigation facilities. This area is neither covered under Savalgi-Tungal LIS coming under Hippargi Project nor in Mulwad

Lift irrigation scheme under KBJNL (formerly Upper Krishna Project). Thus there is a need to extend irrigation facilities to the above mentioned areas for

the benefit and upliftment of the farmers and to mitigate the regional imbalance. The farmers who have been deprived of irrigation facilities in the said

area are demanding for providing them with water for irrigation purpose.

6. Environmental Monitoring Program

The purpose of the monitoring programme 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.

7.2 Positive and Negative impact of the project

• The command area of the project is proposed to be increased from 42,500 ha

to 52,700 Ha (+10,200 ha) with an additional water allocation of 2.473 TMC of

water (totaling to 6.273 TMC) to benefit 61 (+25 villages) in Bagalkot,

Belagavi and Vijayapura Districts. This project will help to increase the

agricultural production which in turn will raise their economic status and

standard of living. This will have major positive impact on the area; especially

entire population in this region depends on agriculture for their livelihood.

• The project requires 2419 Ha of dry and agricultural land owned by some of

titleholders will be lost for the project construction (Canals) purposes, but

they will be sufficiently compensated as per the 2013 Right to Fair

Compensation and Transparency in Land Acquisition, Rehabilitation and

Resettlement Act (2015 Karnataka LA Rules) applicable in the State. None of

the residential or commercial properties are impacted and there is no R&R

and displacement of Project affected peoples.

8. Project Benefits

The proposed expansion Scheme is proposed to accelerate the development of backward, and

drought prone areas. Irrigation is important to the health of the agricultural industry. Some of

the important project benefits are given below:



Ecological benefits:

• Agro forestry will be taken up in command area and it improves the

ecosystem services.

• Canal Bank plantation improves local biological diversity.

Financial benefits:

• 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.

• Extensive agricultural production supplies raw materials to the nearby small

scale industries thereby increasing the economy in the region.

Social benefits:

• No Rehabilitation and Resettlement.

• Altogether 14,015 households in the command area will be benefitted directly

under the scheme.

• The project requires only 2419 Ha for implementation of the scheme and the

scheme does not envisage rehabilitation and resettlement.

• Direct employment opportunities for 350 peoples (50 Technical and 300

construction labourers) are expected to get employment for the construction

of intake channel, jack well cum pump house, raising main, delivery chambers

and distribution network consisting of Lift cum Flow Irrigation System. During

operation phase indirectly labourers will be appointed operation and

maintenance of the jack well.

9. Environmental Management Plan

EMP provides a delivery mechanism to address the adverse environmental impacts of a

project during its execution, to enhance project benefits, and to introduce standards of

good practice to be adopted for all project related work4

Integrated approach during project planning, design, construction and operation work

acts as a better tool for implementation of Environmental Management Plan. The EMP

measures include mitigation or enhancement measures as appropriate to the nature of

impacts and are explained in the following sections. These include:

9.1 Green belt development plan/afforestation

9.1.1 Agro forestry activities 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 programs. 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.
