The factory was established for a capacity of 2500 TCD sugar, 24 MW cogen plant. The factory had expanded capacity from 2500 to 4500, 24 MW cogen power and 60 KLPD distilleries in year 2008. ASL proposes to expand sugar crushing capacity from 4500 to 12000 TCD, distillery from 60 to 90 KLPD and set up 24 to 54 MW biomass power plant for making RS/ENA/Ethanol. The present sugar, distillery & cogen plant has been constructed over an area of 24 acres (9.71 ha), wherein the proposed expansion will also take place. The company has an additional area of 96.5 acres for plantation, composting, spentwash lagoon & other non-plant activities, thus, having total area of 120.5 acres (48.76 ha) under its ownership. This Environmental Impact Assessment (EIA) / Environment Management Plan (EMP) report has been prepared in line with the Terms of References (TOR) issued by MoEF, New Delhi to obtain environmental clearance for the integrated sugar, cogeneration power project & Distillery.
Environmental clearance is a statutory requirement as per EIA Notification (S.O. 1533) dated 14th September 2006. Since the capacity of the proposed expansion of distillery plant is more than 30 KLD, it is covered under Serial 5 (j) of Schedule and category ‘A’ and the capacity of the proposed expansion of cogen power plant is less than 50 MW, it is covered under Serial No. 1(d) of Schedule and category ‘B’ of the EIA Notification. All molasses based distillery and cane juice/non-molasses based distillery (>30 KLD) are listed at S.N. 5(g) (i) (ii) under category ‘A’ and appraised at Central level. It is also required to get the Consent to Establish from Karnataka State Pollution Control Board (KSPCB).
Form-1, Pre-feasibility report for Sugar, cogen power plant & Distillery unit was submitted vide letter no. ASL/MoEF/3016/2013-14 dated 06.11.2013 for consideration of EAC, Industries (MOEF&CC). The proposal was considered by the Reconstituted Expert Appraisal Committee (Industry) (EAC (I)) in its 16th Meeting held on 20th-21st February 2014. The Terms of Reference (TOR) for preparation of EIA/EMP were issued vide letter no. J-11011/373 /2013 –IAII (I) dated April 30, 2014. (copy given in Annexure I)
Thereafter, conforming with MOEF circular dated 24.12.2010, EIA/EMP report was prepared and public hearing was conducted on 22.08.2014. Being a Category ‘A’ project due to the presence of distillery, although the co-gen unit & sugar unit is Category ‘B’, the EIA report is being submitted for clearance to MOEF, New Delhi.

1.3 PROJECT PROPONENT
M/s. Athani Sugars Ltd. (ASL) is a limited company registered under the Companies Act, 1956 under registration no. 08/17806 of 1995 dated 12th May 1995.
Shri Shrimant Balasaheb Patil is the Chairman and Managing Director of the Factory. He initially devoted himself towards establishment of Co-op Lift irrigation Schemes and brought hundreds of acres of dry land under irrigation, enabling the farmers to grow commercial and food crops and raise their standard of living. During the year 1993- 94 & 94-95, he observed that the abundant quantity of cane grown in Athani Taluka was not entirely crushed by Ugar Sugar Works Ltd, as a result the farmers were terribly suffering to find alternative sugar factory to send their cane. To overcome this problem he boldly took the decision to establish a sugar factory in Athani Taluka. Mr. Patil, with the kind co-operation of the farmers and with the help of devoted workers successfully established a 2500 TCD sugar plant at Madbhavi in Athani Taluka during 2001.

1.4.5 Importance to country & region
National Scenario- Integrated Cogen And Ethanol Project
The Govt. of India has acknowledged the overall deficiency of power supply and quality in the country. The importance of decentralized energy generation from renewable sources of fuel, for complimenting centralized fossil fuel based power generation, has been accepted as a way to improve the situation.
The Electricity Bill 2003 approved by the both houses of Parliament, provides de-licensing of power generation and distribution, throughout the country. The renewable energy sources and power generation from renewable sources have been focused in this bill and the States have been guided to increase their share up to minimum 10%.
The fiscal incentives offered for renewable energy generation will continue in the coming period. They primarily include accelerated depreciation, income tax holiday (5 year tax holiday with 30% exemption for next 5 years), customs duty concessions, exemption of Central excise duty & Central sales tax.
The Central Electricity Regulatory Commission and State Electricity Regulatory Commission have come into force to establish tariffs and oversee the electricity sector. The regulatory commissions fixed tariffs for the purchase of electricity by SEBs from all sources including renewable, based on the guide lines from the Ministry of Power and the MNRE, State policies and inputs from the public hearings. The Govt. of India, through the Ministry of Non Conventional Energy Sources (MNRE), encourages all the existing and new sugar units to set up co-gen power plants. In order to achieve the potential of about 5000 MW from sugar mill cogeneration in India, the Ministry has been undertaking promotional efforts under the National Program on Biomass / Cogeneration Power since 1994-95. Apart from providing guide lines to the States for purchase of exportable power from such projects, the Ministry has been offering several promotional and fiscal incentives to this sector.
The specific incentives from the Ministry include interest subsidy for commercial projects from 1-3% depending on the temperature and pressure configuration, subsidy for preparation of detailed project reports and assistance in syndication of loans, financial assistance for State Nodal Agencies, consultants, industry associations for undertaking promotional efforts, etc.
As of April 30, 2007, the power generation capacity in Karnataka was 18061 MW, 56% contributed from the state sector, 20% contributed by the private sector and balance from the Central sector. The T&D losses have been about 35%, compared to average 33% for the country.
Growth of sugar industry in the State started prior to independence in the private sector and in the co-operative sector since 1950 onwards. The policy for sugar industry in Karnataka is in line with the Central Govt. Sugar cane has been the major cash crop growth in the state due to conductive environmental conditions for sugar cane growing, good quality of soil for cultivation and adequate irrigation facilities.

As of March 2006, a total of 1189 Lols/licenses were issued in different parts of the State (between 1998 till 2006) for expanding their existing capabilities and / or for installing new sugar factories.
In India, after protection granted to the sugar industry in 1932, a large number of sugar factories were established in the country. Increase in sugar production resulted in accumulation of molasses, caused unmanageable environmental problem. In 1938 UP and Bihar established a joint committee to overcome this problem by developing alcohol based industries. Today, the distillery industry of India uses only molasses for the manufacturing of alcohol.
Future demand & sugar pricing
A sugar mill of 5000 TCD capacity, will be installed for manufacture of refined sugar of good quality. The sugar market in India is quite up-beat and is expected to continue for a foreseeable future. The current net price of sugar for the factories has been around Rs. 22.00 per Kg. Command area has excellent sugar cane availability with about 11.5% sugar recovery. ASL has also in process to make tie-ups with the big malls in the metro cities along with Mumbai for sale of branded sugar and also exploring possibilities of exporting refined sugar.
Objectives for sugar manufacturing
The objectives of the sugar plant of the proposed integrated project are mainly to manufacture quality sugar for national & international markets at optimum operating and energy efficiency, as well as to provide raw materials for cogen power plant. The integrated project will push the product, which has highest realization in the market at any given time, either sugar or power. The design of the sugar mill and the cogen power plant would match the latest and modern technologies being employed. At the same time, the flexibility of operation, expansion and diversification, also will be available.
1.4.6 Justification for the site
The promoters have extensively and carefully analyzed the present and future scenario of sugar, ethanol and power industries. They studied carefully the present irrigation facilities and surplus cane availability in the command area, as well as future potential of irrigation and additional cane availability.
By virtue of company’s business sugar manufacturing, the company is closely associated with the farmers in the surrounding area. The company’s growth and progress largely depends on the growth and progress of these farmers. This project will further add value to the sugarcane and will assist the company in sustaining and improving the cane price.
Most of the villages in the study area are in Athani Taluka of Belgaum district. The existing sugar cane availability in the study area, existing and proposed irrigation facilities, cane development program underway, as well as agro-climatic conditions, are considered adequate for sustained cane supply for the envisaged capacity

utilization levels, except for draught periods. It is essential for ASL to accelerate cane development in the study area. The proposed state-of -art equipment in the sugar plant will ensure the performance in terms of recovery, plant efficiencies and lowest steam & power consumption for the sugar process. Due to Electricity Act, 2003 opportunities for trade of power are available and ASL should explore them to sell power at higher tariff and improve economic viability of the project. Hence, ASL will have no problems to market all its surplus power.
The plant is already present at the site and it has been selected keeping the various factors in view viz. vicinity to the source of raw material and availability of other infrastructural facilities e.g. land, power, water, transport, communication, approach road and access distances from the nearest highway, railway station, etc. The plant is established in 24 acres from the total Athani owned area of 120.5 acres. The open land will be used to grow sugarcane for the plant.
1.5 SCOPE OF STUDY- DETAILS OF REGULATORY SCOPING CARRIED OUT AS PER TERMS OF REFERENCE
The Environmental Impact Assessment and Environment Management Plan for the project addressing the environment related issues are prepared in accordance with the requirements of terms of reference prescribed by Ministry of Environment and Forest, Govt. of India.
The study evaluates the prevailing environmental conditions. The adverse impacts have been identified and possible mitigation measures have been drawn in order to protect the environment. In order to carry out the study, the baseline environmental scenario has been established at the first instance.
The main objectives of the present EIA study are briefly summarized below:
To establish the baseline environmental scenario.
To identify, predict and assess the impacts of proposed expansion project on the environment.
To prepare a detailed action plan for implementation of mitigative measures.
To suggest preventive measures to minimize adverse impacts and to maximize beneficial impacts.
To suggest a monitoring programme to evaluate the effectiveness of mitigative measures.
To suggest the formation of a core group responsible for implementation of the EMP.
To prepare a capital cost estimate for environment management plan.
To address the concerns of disaster management, CSR and points raised in public hearing.
Any industrial project is expected to cause environmental impacts near the project site during its operation phase. The type and intensity of impacts on various
Athani Sugars Limited
EIA/EMP for Expansion of Sugar, Distillery & Cogen Plant in Dist. Belgaun, Karnataka 1-9
components of the environment vary depending upon the nature and size of the project as well as its geographical location. The net impacts from individual project can be quantified through Environmental Impact Assessment studies of various components of environment such as noise, air, water, land, biological and socio-economic aspects. EIA studies form a basis for preparing an Environment Management Plan (EMP) to conserve the environment of the area. The total EIA study for a particular project site can be divided into three phases. The first is identification of significant environmental parameters and then assessing the existing (pre-project/ pre-expansion) status within the impact zone with respect to environmental descriptors. The second phase is prediction of impacts from proposed project/ expansion on identified environmental parameters based on experience of other projects. The third phase includes the evaluation of total impacts after superimposing the predicted impacts over baseline data. This helps in incorporating proper mitigation measures wherever necessary for preventing deterioration in environmental quality.
The scope of the present study is to conduct EIA covering all the disciplines of environment and field monitoring in relevant disciplines over one full season of 3 (three) months (excluding monsoon months). The draft EIA report is prepared as per the MoEF Notification dated 14.09.2006. After completion of the Public Consultation, all the environmental concerns expressed during the Public Consultation process have been addressed and appropriate changes in the draft EIA Report have been made accordingly to formulate the Final EIA Report. The final EIA Report is being submitted to be presented to the Expert Committee (EC) of MoEF. Any queries raised by will be clarified and replies will be submitted to them.
The project area is termed as "core zone". The area within 10 km radius around the periphery of the project boundary has been considered as the “buffer zone” for identifying and assessing impact with respect to air, water, noise, land use, ecology and socio-economic environment. The core zone and buffer zone together comprise the "study area". The studies covering all individual components of environment are described in detail in subsequent chapters. The preparation of the EIA/EMP was proposed as per the generic structure prescribed in EIA Notification dated 14th September 2006, as follows:

2.3 PROCESS DESCRIPTION
2.3.1 Sugar alcohol and cogeneration process
Cane from nearby area will be crushed to get sugar cane juice which will further be concentrated to get quality sugar crystals. Uncrystallised sugar collected in molasses will be fermented to form alcohol with Yeast cells.
C12H22O11 + H2 O Enzyme Invertase 2 C6H12O6C6H12O6 Enzyme zymase 2 C2H5OH + 2 CO2
On a theoretical basis 342 kg of sugar yields 184 kg of 100% alcohol and 176 kg of CO2.Usual commercial efficiency obtained are in the range of 85% fermentation and 98 to 99% distillation, contributing to a total efficiency of 83 to 84%.
Ethanol or ethyl alcohol, CH3-CH2-OH is a volatile, flammable, clear, colourless liquid which finds many applications as a raw material for acetone, acetaldehyde, acetic acid, acetic anhydride, ethyl acetate, other esters, and syntheses along with its main use due to associated oxygen from hydroxyl group in fuel blending in gasoline.
Alcohol distillation will yield quality rectified alcohol. Spent wash will be used along with press mud for composting. Bagasse from cane crushing will be burnt in 130 T/H boiler for cogeneration of 24 MW power with turbo generator. Press mud from cane juice filtration will be used in composting and the same will be supplied to cane farmers. Ash from boiler will be sold to brick producers or used in Biocopmposting.
Following parameters and their basis are considered while designing the plant. as indicated in the following Table 2.2.

2.3.2 Manufacturing process for sugar
2.3.2.1 Sugarcane
Cane is harvested at the field quality cleaned cane is transported to the factory cane yard.
2.3.2.2 Cane Yard
Cane is weighed at the yard without error. Yard balance is maintained as equal to 2-3 hours crushing rate with respect to the factory capacity. Spillage of cane may be avoided. If tops are more, it may be removed. If there is any error in cane weighment, it should be corrected then and there.
2.3.2.3 Cane Carrier
Weighed cane is unloading into the cane carrier by mechanical means. Overload to the cane carrier may be avoided by using feeder table for uniform feeding.
2.3.2.4 Mill House
The weighed cane is fed to cane carrier with the help of cane un loaders. The cane carrier takes the cane to milling units via kicker, chopper, leveler, and fibrizor. The kicker controls the height of cane blanket in the carrier. The chopper and leveler cut the cane in to small pieces. And finally the fibrizor or shreds the cane pieces. This is called prepared cane. The milling unit has four mill tandem each mill consist of three rollers namely feed, top and the discharge. Prepared cane is fed to first mill and from first mill primary juice (without any addition of water) is extracted. The bagasse coming out from the first mill is fed to second mill and so on.

The last but one mill the imbibition water at the rate of 250-275% on fiber with temperature 65-70 °C is added. The lighter juice extracted from the last mill is added to previous mill and the juice extracted in that mill is passed to the previous mill. Thus the system is known as compound imbibition system is followed for getting good mill extraction. The roller RPM is maintained 4.5 5.00 and the hydraulic pressure is maintained at 108 200 kg/cm2 g for better extraction. About 95-96% of sucrose is extracted in the mill juice from the cane. The final solid called Bagasse goes to boilers and juice goes to processing section through DSM screens. The final output bagasse from fourth mill contains 2.2% of sugar and 50% moisture. This bagasse is supplied to the boiler unit through rake elevators.
2.3.2.5 Boiling house
Clarification, Evaporation and Crystallizations are taking place in the Boiling House.
1. Clarification:
a) Juice Weighing Scale:
Mixed juice form the mills is weighed accurately with automatic juice weighing scale and discharged into raw juice receiving time. Filtered juice from vacuum filter is also added with raw juice in the raw juice tank.
1. Mixed juice pH -5.2 5.4 2. Mixed juice dirt % -0.30-0.40%
To correct the error in weighment of juice weight of juice per tip is checked every day. Clarification is nothing but removal of maximum and coloring matter from raw juice to getclear juice to produce better quality sugar minimum final molasses purity. Whenever the time permit apart from clearing period, raw juice tank should be washed and sand deposited in the raw juice tank should be removed to avoid carryover of the sand to the process. Ortho phosphoric acid is added to maintain 275-325 ppm of phosphate in raw juice before clarification.
b) Raw juice heater (Primary juice heater):
Raw juice is heated to 65 - 70°C. by second or third vapor in order to avoid Inversion, to kill microorganisms and for better reaction with of lime and SO2 gas at the reaction vessel i.e., maximum formation if calcium sulphate may be more at this temperature and thereby maximum absorption of coloring matter and other non-sugar with calcium sulphate may be more.
c) Juice Sulphiter (Reaction Vessel):
Raw juice at 65-70°C is mixed with milk of lime to raise the pH to 9.2 - 9.5 and then SO2 gas is passed to reduce the pH to 7.3 - 7.4. This condition should be maintained to remove maximum non-sugar and coloring matter from the juice. The retention time of the juice sulphitation may be in the range of 10-12 minutes. Brix of the milk of the lime added into the juice may be in the range of 8-10 brix. Milk of lime should be free from grid. Calcium oxide content in burnt lime should be above 70%. Grit should be below 2%.
Athani Sugars Limited
EIA/EMP for Expansion of Sugar, Distillery & Cogen Plant in Dist. Belgaun, Karnataka 2-10
d) Treated juice heater (secondary juice heater):
Treated juice from juice sulphiter is again heated to 1.2 - 1.4°C to get its point at the treated juice heater by vapor from SK 1 and if necessary by exhaust as correction heater. Depending upon the brix % of the mixed juice, the temperature may be maintained in the juice heater.
e) Clarifier (Dorr):
Juice from treated juice heater is pumped through splitter box into the clarifier for setting is nothing but removal of coloring matters and non-sugar as solids (Flocks) from juice to get clear juice. Splitter box is used to reduce the velocity of juice before going to the clarifier and to release the air from the juice. Settling aid 0.4-0.8 ppm (magno flock) is also added into the clarifier to increase the settling rate of mud and to get the better quality clear juice. Clear juice is taken as overflow method to avoid the carryover of mud through the clear juice. Outlet clear juice pH may be maintained 7.0 - 7.1 with the temperature of 97-98°C. Clear juice should be free from colloids (suspended matter) and bagacillio (or) any mud particles and it may be highly transparent and golden yellow color.
If phosphate content is below 100 ppm in clear juice, Ortho phosphoric acid may be added externally in the clear juice to maintain 100 - 110 ppm of phosphate in order to get spongy nature of scales in the evaporations, for easy removal.
Muddy juice from the bottom of the clarifier may be taken continuously to the vacuum filter mud level in the clarifier should not be above 2 cores. When the setting problem occurs in the clarifier, rate of crushing should be reduced and after satisfying the settling problem, crushing may be continued.
f) Vacuum Filter:
Muddy juice is taken to the vacuum filter to remove juice and mud as filter cake. This is done by proper washing with hot water of 65-70 °C and with 16-20 inches of vacuum. The filter juice is turbid in nature and taken to raw juice tank for processing. The moisture % filter cake may be 70-75% and pol% may be 1.8 - 22% addition of bagacillo to the muddy juice should be free from sucrose.
2. Evaporation:
Evaporation is nothing but the maximum removal of wash water from clear juice to concentrate the clear juice from 12-13 brix to 55-60° brix %. Clear juice is having 12.5-13.5% solids and 86.5-87.5% water. Out of 87% water nearly 75-80% of water has to be removed as vapors in the evaporators which consist as follows:
Double effect vapor cell - quadruple effect evaporator (or) Quadruple effect evaporator (or) Quintuple effect evaporators.
It is possible to evaporate nearly 80% water from clear juice only when juice evaporated in multistage evaporators in a serious manner.

a) Clear juice Heater:
Clear juice is at 97-98 °C is heated in clear juice heater to 110-115 °C. by exhaust before taken to semikestner in order to maintain before evaporation i.e. semikestner to produce maximum vapors at higher temperature 110-112 °C to using for juice heater and pan boiling without using exhaust. It is for better steam economy.
b) Semi-kestner (1):
Clear juice from clear juice heater is heated by exhaust to around 120°C and the vapor produced in SK-1 may be having 0.3-0.4 Kg/cm2 g. pressure at 110-112 °C. This vapor is taken for C massecuite boiling in pars and for treated juice heater nearly 28-30% water is evaporated in SK-1.
c) Quadruple Evaporators:
i. Evaporator: SK juice is heated in first evaporator by exhaust. The temperature of vapor inside the body may be 102-103 °C nearly 12-14% of water is evaporator in first evaporator. This vapor is used to heat the juice from second evaporator.
ii. Evaporator: Juice form first evaporator is heated in II evaporator by first evaporator vapor. The vapor temperature in second evaporator may be 92-94 °C. This vapor is again used to heat the juice in third evaporator. Nearly 12-14% water is evaporated here.
iii. Evaporator: Juice from second evaporator is heated in third evaporator by the vapor from second evaporator. The temperature of vapor in the third evaporator may 82-83 °C. The vacuum in the body may be 12-14 inches. The vapor is used to heat the juice from fourth body. Nearly 12-14% water is evaporated in third evaporator.
iv. Evaporator (Last Body): The juice from third evaporator is heated in fourth evaporator at 25-26 inches Vacuum to reduce the boiling point of syrup thereby to reduce the color formation and to reduce inversion losses. Third evaporator vapor is used to heat the juice in fourth evaporator. The concentrated juice from fourth evaporator is called as un-sulphited syrup.Brix % un sulphited syrup may be 55-60° Brix pH of un sulphited syrup may be 6.4-6.6 pH. The vapor at 56-60 °C from fourth body evaporator is going to condenser to condense and thereby to spray pond through injection pit.
To avoid the entrainment of juice, nearly 1:3rd calendria level (tube light) may be the boiling level in all the evaporators.
Retention time of the evaporators may be 25-35 mts.
d) Syrup Sulphitation:
Un-sulphited syrup may be having high coloring matter and coloring content. In order to reduce this to the minimum un-sulphited syrup should be sulphited by SO2 gas as double sulphitation for better bleaching. The sulphited syrup should be with pH 4.6-4.8, Brix 55-60% and color - Golden yellow, free from colloids (or) any suspended matter to be highly transparent. The retention time of syrup sulphitor may be 8-10 mts for better

bleaching. In order to have uniform bleaching of syrup chocking of SO2 gas lines if occurs should be cleaned then and there. Sulphited syrup is taken to supply tank for storage before use it for pan boiling. Sulphur purity should be above 99.5%.
3. Crystalisation: Crystallization is nothing but the formation and developing of purse sucrose Crystals by taking sucrose molasses from the syrup (or) any other molasses. In order to get pure sugar crystals to the required grade and to get the minimum final molasses purity multi massecuite boiling is practiced. Based on crystal size massecuite purity. A-massecuite, B-massecuite and C-massecuite are boiled as standard three massecuite boiling.
(i) A-Massecuite Boiling: It consists of two steps a) A-Footing preparation b) A-Massecuite preparation
a) A-Footing preparation: A-Light molasses, melt, syrup and B-Seed magma is taken to prepared A-Footing material while curing A-Footing may be having Brix 88-90%, Purity 88-90 and Crystal Size of 350-450 microns with uniform crystal size. A - Footing may be prepared for boiling three (or) four A - Massecuite Boiling.

(ii) B-Massecuite Boiling: It consists of two steps
a) B-grain preparation b) B-Massecuite preparation
a) B-Grain Preparation: A - heavy molasses is taken through conditioner and concentrated to 86-88 Brix and calculated quantity of slurry is fed into the pans. Sucrose nuclear form may be developed as grains. After forming grains, graining should be established and should be hardened with movement water. Movement water may be hot water at 75-80°C or calendria water at 95-98° C. During hardening feeding materials except hot water should be avoided. After hardening movement water should be stopped. Feeding material of A-heavy molasses may be taking for further boiling. After attaining the required grain size 160 - 180 microns and after reaching the capacity of the pan, the mass is to be concentrated to 90-92-brix%. Then two third of grain may be transferred into B-Vacuum crystallizer for further boiling and one third of the grain may be kept in the same pan for B-massecuite boiling.
b) B - Massecuite Boiling: A-heavy molasses may be cut as mother liquor to develop the B-grain to the required size of B-massecuite crystals to 275-325 microns. After getting the required size of the crystals after reaching the pan capacity-feeding materials may be stopped and the moss may be concentrated to 96-98-brix%. Then B-assecuite may be developed into B- Massecuite Cristalisers. B-Massecuite may be having Brix 96-98%, Purity 68-70 and Crystal Size 275-325 microns.

(iii) C-Massecuite Boiling: It contains two steps.
a) C-Grain preparation b) C-Massecuite Boiling
a) C-Grain Preparation: One third of A-heavy molasses and two third of C-light molasses may be taken through molasses conditioner and may be concentrated in the pans to 86-88 Brix%. After attaining the concentration required quantity of slurry may be introduced into the pall sucrose nuclio seed from the slurry may be formed as grain and the formed grain is to be harden. After establishing the grains, movement water (hot water or calendria water) is to be fed until the grains are to be well harder. Movement water is used to maintain the same super saturation co-efficient in the meta-stable zone throughout the hardening the process. During hardening except movement other molasses should not be given to the pans. After hardening the grains, C-light molasses if available or B-heavy molasses may be fed. After getting the required C-grain size 80-100 microns and after reaching the capacity of the pan the feeding material is to be stopped. The moss is to be concentrated to 90-92 brix%. Then two third of C-grain may be transferred into C-Vacuum crystaliser. One third of C-grain may be kept in the same C - pan for further boiling. The cutting grain should have Brix 90-92%, purity 50-52 and grain size 80-100 microns with uniform grains.
(b) C-Massecuite Boiling : One-third the C-grain in the C-pan may be developed further by taking B-heavy molasses to 140 -160 microns. After attaining 140-160 microns crystals, B-heavy should be stopped and the boiling moss may be concentrated to 100 - 101 brix% then the C-massecuite may be dropped into receiving C-massecuite crystallizer. The C - massecuite is having Brix 100-101%, purity 48-50% and Grain size 140-160 microns with uniform grains.
Note:
1. Pan boiling should be done only in meta-stable zone.
2. If falls grains are formed during, it should be dissolved by water and then boiling should be continued.
3. Required quantity of C-grain from vacuum crystallizers may be again taken to C- pan to boil C - massecuite.
4. Required quantity of B- grain from vacuum crystallizers may be again taken to B-pan to boil B - massecuite.
5. Required quantity of A- grain from vacuum crystallizers may be again taken to A-pan to boil A - massecuite.
6. Crystal % A - massecuite may be 50-52%
7. Crystal % B - massecuite may be 40-42%
8. Crystal % C - massecuite may be 30-35%
Athani Sugars Limited
EIA/EMP for Expansion of Sugar, Distillery & Cogen Plant in Dist. Belgaun, Karnataka 2-14
2.3.2.6 Crystallizers
Massecuite dropped from pans are having 62-65°C, which contains more sucrose in mother liquor. The sucrose from the mother liquor has to be defused and deposit on the exiting crystals for the further growth of crystals in order to get more crystal yield and minimum molasses purity.
A-Massecuite Crystallizers : A-Massecuite Crystallizers from pan is dropped as 60-65 °C in to A-massecuite crystallizer and cooled by air to 56-58°C for 4-5 hours. Then the cooled massecuite is taken to A-centrifugal. During cooling of massecuite sterring should be there. A-massecuite cooling is done to increase the bagging % massecuite and to reduce the A - heavy molasses purity.
B-Massecuite Crystallizers : A -Massecuite from B - pan at 62-65°C is dropped into B - massecuite crystallizer and cooled by air cum cooled water to increase exhaustion i.e., to increase crystal yield and to reduce the heavy molasses purity in order to avoid re-circulation of molasses. B - massecuite may be cooled to around 8 hours to get the temperature of B - massecuite to 52-54 °C stirring should be continued.
C-Massecuite Crystallizers : Massecuite from pans at 60-65°C is dropped into receiving C-massecuite crystallizer for air-cooling to 6-8 hours to get 56-58°C. Then this massecuite is pumped to vertical srystaliser for further cooling. Stirring should be continued.
Vertical Crystallizer: Vertical is used to cool the C-massecuite further to 40-42°C by cold water in order to improve exhaustion i.e. to get more crystallizers and to reduce final molasses purity to the minimum. Stirring should be continued.
2.3.2.7 Centrifugal Section
Centrifugal are used to separate the molasses from massecuite, to wash the sugar crystals and to dry the sugar crystals.
Based on massecuite quality different types of centrifugal are used for curing.
(i) A-Heavy massecuite curing: Single curing is adopted in A-massecuite boiling first superheated wash water at 120 - 125°C with 5-6 kg/cm2 g. Crusher is used for complete washing of molasses layer around the sucrose crystals. The molasses obtained by washing is known as A-light molasses. A-light and A-heavy molasses separator should be all right. Otherwise mixing of these molasses finally take place. This may affect the quality of B - massecuite or A-massecuite. Superheated wash water is used not only for washing and purifying of crystals but also self-drying of sucrose crystals. The sugar discharge from the A-machine may be having the temperature of 75 - 80°C and massecuite of 0.5 - 2.0%.
(ii) B-Massecuite Curing: Continuous centrifugal is used at around 1600 RPM. Hot water at 75 - 80°C superheated wash water at 115 - 120°C for washing of sucrose crystal. B - heavy molasses purity may be maintained in the range of 46 - 48 and B - seed purity may be maintained above 98 nearly 25% of B - seed may be used for A- boiling and remaining 75% of B - seed may be crystallized completely and taken for A - massecuite boiling. Mesh size used for B - centrifugal may be 0.06 mm or 0.09 mm. Now a days, single curing is
Athani Sugars Limited
EIA/EMP for Expansion of Sugar, Distillery & Cogen Plant in Dist. Belgaun, Karnataka 2-15
adopted in B - massecuite curing. According to the quality load may be adjusted. A - heavy molasses is separated then.
(iii) C-Massecuite for curing: Cooled C-massecuite from vertical crystaliser at 40-42°C is re-heated by transient heated before curing to its saturation temperature 52-54°C. This is for better purging (Separation) of final molasses from the crystals. Continuous centrifugal is used at 2000 RPM to separate final molasses from the crystal. Hot water at 50-55°C or diluted final molasses at 20-25° brix or cold water at 30°C is used as lubrication for C-massecuite curing. In order to separate the final molasses in a better manner and to get better quality C-fore sugar and minimum final molasses purity.
Optimum load may be maintained for better purging. C-fore sugar at 78-80 purity is mixed with C-light molasses at 56-58 purity to get C-fore magma mixture for C - after curing. Mesh size used may be 0.05 to 0.06 mm for C-fore centrifugal machine.
C - After curing: Continuous centrifugal is used at around 1800 RPM to separate C - light molasses from magma and to get C seed purity above 97. Hot water at 75 - 80°C or superheated wash water at 115 - 120°C is used to wash the sucrose crystals completely and easily to maintain the C- seed purity to above 97. C light molasses may be in the range of 56 - 58. Mesh size used for after centrifugal may be 0.06 mm.
C - Seed obtained may be completely melt and taken for A - massecuite boiling.
2.3.2.8 Sugar Hopper
Sugar discharged from the machine is having higher temperature and moisture content. This may not be bagged as it is. Hence, this sugar is to be dried and cooled to 38 - 40°C. Hot air blower at 90 - 95°C is used to dry the sugar crystal and cold air blower is used to cool the sugar to 38 - 40°C. Lumps breaker is used in the second hopper to break the lump sugar is there, it should be removed from the end of the hopper before going to the sugar elevator.
2.3.2.9 Sugar Elevator
Cooled sugar from the hopper is taken to the sugar grader by sugar elevator buckets.
2.3.2.10 Sugar Grader
Sugar is distributed over distribution box and sieved through grader to get different size of crystals for bagging separately with respect to its grade. Mesh size 8, 14, 20, 26 or 28 mesh may be used in the grader.
2.3.2.11 Sugar Bin
Sugar from the grader is grader is stored in the sugar bin before bagging.
2.3.2.12 Sugar Weighment
Sugar from the sugar bin is weighed automatically and bagged. The bagged sugar is stitched and taken to sugar go-down.

2.5.1 Raw materials, products, waste formation in alcohol fermentation
A. Raw Material Handling
Molasses from the bulk storage tank located in the sugar manufacturing unit premises is pumped into a molasses day storage tank T- .Between the passages of these two tanks it is filtered to remove any grit or macro size foreign substances by a basket filter/strainer. T-108 tank bottom is connected to the suction of a pump no. P 101-A/B via lines 13016-MOL no.13018-MOL, 13019-MOL. It is delivered to tank no.T-109 by this pump via lines.13023-MOL, 13024-MOL. T-108 has a dedicated bottom drain via line no.13016-MOL.
Tank T-109 is meant for weighing the molasses in batches before it is delivered in the process. The 24 hours count of molasses used and alcohol produced will give us the figure of overall process efficiency. A flow control valve FCV-1 is located on this delivery lines. This valve shall switch ON/OFF to deliver a determined quantity of molasses in the tank no.T-109 / process per hour. From tank T-109 weighed quantity of molasses shall be sent to Tank T-11O called weighed molasses receiving tank via line 13025-MOL.
The bottom of the tank T-110 is connected to the suction of the pump P-101 C via a line no.13026-MOL. By this pump the weighed molasses shall be served in the process via line no.13027-MOL. This line joins a common header line 13028-MOL which distributes molasses to yeast propagation section and line 13027-MOL meeting the molasses demand of fermentation section.
B. Yeast Propagation Section
As explained earlier that the molasses is diluted with water to achieve a specific desired sugar concentration and it is subjected to the action of yeast in the fermenters. Yeast cells secret enzymes which convert these sugars in molasses to ethyl alcohol. In order to fulfil the fullest capacity of a given alcohol plant the yeast employed has to process many tonnes of molasses into alcohol in shortest time. The width of a single yeast cell is around 1-5 microns and the length is around 20-30 microns. It is practically found that we have to maintain a population of around 300-450 million live and viable yeast cells per mili-litre of molasses broth in the fermenters. It is not feasible and economic to add the required huge mass of yeast externally on day to day basis.
Yeast cell has got an inherent property to multiply (reproduce) itself asexually by forming buds on its cell wall in shortest time. These buds detach, form a new adult cell and give rise to multiple cells by budding. This property of yeast to meet the required yeast population in molasses broth in the fermenters is utilized.
Athani Sugars Limited
EIA/EMP for Expansion of Sugar, Distillery & Cogen Plant in Dist. Belgaun, Karnataka 2-21
The yeast propagation section is meant for generating an active yeast biomass of selective yeast breed by way of reproductive multiplication.
This section serves as yeast catering unit for fermenters. The section includes a set of four vessels progressively connected in series namely yeast culture propagation vessel number 1, vessel number 2, number 3 and fourth and final vessel called a pre-fermenter. All of these vessels are equipped with supply of clean sterile air, water and molasses feed. All these utilities are to be added in a measured quantity to each vessel as the vessels are equipped with individual flow metres for the same. Also a cooling jacket and plate heat cooler is provided to cool the contents of these vessels. Yeast acts best at temperature range 27 c to 32 c in our case.
Pure and cultured yeast of precisely defined characteristic grown/preserved in the test tubes holding slanted synthetic media is used. The yeast formed as colonies on this slanted medium is further propagated in the laboratory under strict sterile condition successively in a 500 ml, 1000 ml and 2500 ml. culture flasks using an ideal synthetic medium. The final and finished culture flask from the laboratory culture preparation is transferred aseptically to the yeast culture vessel no.1 in the plant which is holding around 100 litres of clean and low sugar content molasses medium. Clean and sterile air is passed through the vessel content continuously as yeast needs oxygen for reproduction process. Yeast multiplies in this vessel. After around 12 to 18 hours it can obtain the desired concentration of yeast cells in the molasses broth say some 300-450 million cells per ml of broth. The broth rich in cell mass from vessel no.1 is now transferred to culture vessel no.2 holding around 750 litres of clean and low sugar content molasses medium. Clean and sterile air is passed through the vessel content continuously. After around 12 to 18 hours it can obtain the desired concentration of yeast cells in the molasses broth say some 300-450 million cells per ml of broth. The vessel no.2 contents are now transferred to culture vessel no.3 having capacity around 1500 litres. Clean and sterile air is passed through the vessel content continuously. After around 12 to 18 hours we can obtain the desired concentration of yeast cells in the molasses broth say some 300-450 million cells per ml of broth. Finally the contents of third vessel are passed to the prefermenter to achieve similar cell concentration. Prefermenter volume is around 18000 litres. The loaded prefermenter rich with fresh yeast cell mass is transferred to the main fermenter. The cell mass continuous to grow in fermenter and attains a desired cell concentration. This cell mass is maintained in the fermenter throughout during the continuous cascade fermentation mode operation. Propagation in this mode is carried out only at the initial start up or inception of the process or after a prolong shut down resulting in emptying of fermenters.
During the batch fermentation mode we can distribute the finished pre-fermenter between 2 main fermenters. We can recharge the pre-fermenter again immediately and cater the next two fermenters.

FIG 2.8: CONTINUOUS CASCADE FERMENTATION SYSTEM
=
In the outset itself we have discussed what fermentation section stands for. Four no. fermenters T-104, T-105, T-106 and T-107 have been installed in series. Each fermenter is equipped with sloping bottom and bottom drain, bottom and top manhole, sight glass, breather valve to release excess pressure, vent to release the gases evolved during fermentation process, individual plate heat cooler with pump to cool the fermenter contents and nozzles to feed molasses, water, air (in metered quantity through flow metres), antifoaming agent, nutrient etc. Fermenter section is connected to a yeast propagation section to receive the propagated yeast mass. The fermentation tanks are in progressive series, that is, the contents of first fermenter T-104 flow to T-105 to T-106 so on. However a provision is made to isolate these four tanks from each other to use each tank in a standalone status.
The fermentation process can be brought about in two modes. (We have made this provision in the design) By continuous cascade type (recommended and preferred) or by batch type (route chosen if raw material molasses, water etc. is scanty)
Continuous Cascade Method
In this mode the substrate i.e. molasses is fed and fermented continuously into the first three of four fermenters placed in series and the outflow of one fermenter is allowed to flow in the next fermenter progressively. Yeast mass is generated continuously in the first two fermenters. The diagram shown on the previous page illustrates this mode.

The fermenters are cleaned and kept ready. The first fermenter T-104 is filled 1/10th of its total volume with dilute molasses of around 1040 S.G. Now the matured pre-fermenter is transferred to this T-104.The contents of the fermenter are kept undisturbed for around 2 hours to allow the nascent yeast cells of pre-fermenter to adapt itself. This is called as log phase. After two hours we start feeding this fermenter with molasses and water slowly. Yeast starts fermenting the molasses and simultaneously growing and multiplying itself now. The feed of molasses and water is so adjusted that around 4-5% residual sugar concentration is maintained thought in the fermenter broth. Air is supplied to the propagation broth continuously. The rate of feed is so employed that it shall take around 26-30 hours to fill the tank to its full capacity. This retention is given to generate the yeast mass to the desired count of 400-600 million cells per ml. of broth in all the fermenters. The contents of T-104 are now with slow rate transferred to T-105 with adopting the same procedure followed for first fermenter. This is followed till the last fermenter (except the last fermenter is not fed with substrate).
From the last fermenter the final wash is drawn in the wash holding tank. After filling the wash holding tank the wash is sent for distillation at slow feed rate. This rate is gradually increased and set to desired feed rate for full capacity production. Concurrently the dilute molasses feed to the first three fermenters is increased to keep the fermenters and wash holding tank full to the capacity throughout. The sugar concentration of the molasses feed is so selected that it shall generate around 5.5% v/v alcohol in T-104 and around 2% v/v in T-105 and around 1.5%v/v alcohol in the third T-106 fermenter. Final wash shall have around 8.5%v/v alcohol concentration. Please note that contents of each fermenter are overflown to next fermenter. This operation of generation of yeast cells in the fermenter broth and
We shall corroborate the yeast population by serving intermittent doses of matured prefermenter to the T-104.
Additives like urea and Di- ammonium Phosphate as a source of nitrogen are added in the fermenter as and when required. Nitrogen addition favours fermentation rate and also prevents formation of impurities like higher alcohol during the fermentation. The upsurge of foam in the fermenter head space is controlled by addition of surfactants like surface tension. Every litre of alcohol produced generates about 270 Kcal of heat in the fermenters. This excess heat is removed by continuous circulation of the fermenting wash through external plate heat exchangers PHE 102/3/4/5 called the Fermenter Cooler. The fermenter temperature is always maintained between 32°C, and 34°C, the range optimum for efficient fermentation.
The carbon Dioxide which is generated in the fermentation process carries along traces of ethyl alcohol up to 0.8% to 1% v/v. Before letting it in the atmosphere or recovering by purification it is passed through a carbon dioxide scrubber C-11 whereby it is scrubbed by water. This water containing ethyl alcohol is returned back to the fermenter. This minimises the alcohol loss in the atmosphere via carbon dioxide evolution.

Batch fermentation
This is the old and out-dated method of fermentation. However it is followed under some exceptional conditions even now.
We have made our fermentation section design versatile. It can handle the batch mode also.
A clean and standalone fermenter is filled with dilute molasses to its around 1/10th capacity. A matured pre-fermenter is transferred to this. Contents are left undisturbed for around 1-2 hours. Then the fermenter is filled rapidly to its full capacity within a span of 3-4 hours maintaining molasses gravity 1100 SG throughout, the fermenter is left alone. The fermentation will conclude within a span of 32 to 38 hours producing 8.5% v/v alcohol. This fermenter is distilled by drawing the wash directly to distillation.
C. Fermentation
Cane Molasses, a waste generated from cane sugar manufacturing process is used for the production of ethyl alcohol. Molasses contains about 50% total sugars, of which 30 to 33% is cane sugar & the rest are other reducing sugar. These sugars present in the molasses are subjected to the action of yeast of the species Saccharomyces cerevisiae, a living unicellular microorganism belonging to class fungi. Diameric sucrose undergoes decomposition due to metabolic activities of yeast and monomeric invert sugars such as glucose and fructose are produced in inversion process. Fermentation of these total invert sugars in the molasses broth gives ethyl alcohol and carbon dioxide. This is an exothermic (heat evolving), biochemical reaction brought about by the action of certain enzymes secreted by the yeast. For bringing out above biochemical reaction requires proper & careful handling of yeast, optimum parameters like pH, temperature & substrate concentration to be maintained in the fermenter vessels which results into effective conversion of sugars to alcohol.
D. Post clarification system of fermented wash by gravity settling system and decanter
The post clarification of fermented wash is brought about by well-designed gravity settlers system. The fermented wash from the last fermenter (in case of continuous cascade fermentation) is collected in a sludge settling tank no.T-111.This.tank has large conical bottom. The sludge and used yeast in the wash settles at the bottom cone of T-111. The clear wash is drawn by overflow from the top of this tank (leaving the bottom contents of tank undisturbed) to a buffer tank to send to distillation section. The settled mass at the bottom of T-111 is diluted with water and sent to a sludge washing tank T-112.From this tank it is fed to a sludge decanter centrifuge D-101. The decanter separates the sludge mass which is discarded. The sludge free liquid from decanter recycled in the system for alcohol recovery.
This helps in reducing the sludge in fermented wash allowing clear liquid to enter the distillation. This will minimize the scaling of the distillation columns as well as other equipment. This also avoids a caramalisation and charring of wash under distillation which imparts burnt and other off flavors to final product.

Flexibility:
This process accords tremendous flexibility to the operator. Process conditions and plant design can be varied to suit individual requirements of alcohol quality, effluent concentration and characteristics. This unit can give spent wash suitable for use in any effluent treatment process. More details of this feature of process flexibility can be supplied on request.
E. Multi Pressure, Multi-Product Distillation (EQRS, EQENA, AA Molecular Sieve)
The Distillation Plant offered is a Multi pressure Multi product distillation system with all prescribed auxiliary equipment and services as required to produce, as a minimum, the desired ethanol quality. The system consists of total 4 nos. column along with related condenser, coolers, pump, piping, etc.
The distillation columns provided are as follows:
Analyser column
Extractive distillation (Hydroselection) column
Rectifier column & Recovery column
The above distillation system is run as below for following products:
Export Quality RS : Analyzer Column (Atmospheric) Hydroselection column (Atmospheric) Rectifier (Pressure) Recovery column (Atmospheric)
While producing Export Quality RS, the hydroselection column is run at lower dilution. The analyser and Extractive Distillation column are run in vacuum. The overhead vapours of Rectifier are fed to the Analyzer re-boiler. The product is drawn from the top of the Rectifier Column. The operation of Rectifier under pressure enables to operate the Analyzer under vacuum. The direct benefit of such Pressure Vacuum system results in energy saving and reduces down time in plant operation (cleaning of scales in Analyser Column). This further ensures very good quality of product.
ENA Column: Analyzer Column (Atmospheric) Hydroselection column (Atmospheric) Rectifier (Pressure)
The system is operated in the same manner as detailed for EQRS operation. However, the Extractive column is operated under higher dilution rate. In order to ensure the ENA quality, the refining column is used in the system for further removal of traces of impurities.
Recovery column is used in the system for further removal of traces of impurities.
Athani Sugars Limited
EIA/EMP for Expansion of Sugar, Distillery & Cogen Plant in Dist. Belgaun, Karnataka 2-26
Anhydrous Alcohol: Analyzer Column (Atmospheric) Rectifier (Atmospheric)
The rectifier is operated under pressure. The overhead vapours of the Rectifier are used to heat the reboiler of the Analyzer. Part of the vapours of the rectifier are sent to the superheater of the Molecular sieve plant. Superheated vapours are passed through the molecular sieve plant. Superheated vapours are passed through the molecular sieve beds for dehydration.
The vapour passes through a bed of molecular sieve beds and water in the incoming vapour stream is adsorbed on the molecular sieve material and anhydrous ethanol vapour exists from the Mol Sieve Unit.
Hot anhydrous ethanol vapour from the Mol Sieve Units is condensed in the Mol Sieve Condenser. The anhydrous ethanol product is then further cooled down in the product cooler, to bring it close to the ambient temperature.
The two Mol Sieve Units operate sequentially and are cycled so that one is under regeneration while the other is under operation, adsorbing water from the vapour stream. The regeneration is accomplished by applying vacuum to the bed undergoing regeneration. The adsorbed water from the molecular sieve material desorbs and evaporates into the ethanol vapour stream. The mixture of ethanol and water is condensed and cooled against cooling tower water in the Mol Sieve Regenerant Condenser. Any uncondensed vapour and entrained liquid leaving the Mol Sieve Regenerant Condenser enters the Mol Sieve Regenerant Drum, where it is contacted with cooled regenerant liquid.
The cooled regenerant liquid is weak in ethanol concentration, as it contains all the water desrobed from the Molecular Sieve Beds. This low strength liquid is recycled back to the Stripper / Rectifier Column for recovering the ethanol. The water leaves from the bottom of the column and contains only traces of alcohol.
Bio-fertiliser
This process has been specifically developed to treat distillery effluent- spent wash with organic matter like press mud. This process not only helps you in solving your effluent treatment problem, but also produces valuable Biofertilizer. The process does not give any liquid discharge after the treatment. This is a zero pollution process in real terms. This process produces good quality compost which is a valuable product for farmers.
The process mainly uses a machine called which is manufactured by Alfa Laval in India. The machine aerates the mass of press mud and spent wash to treat the mixture aerobically. Alfa Laval also supply bioculture, namely, Micro 110 for speedy decomposition of organic matter. Besides this, they supply complete knowhow for practicing Bioearth Scientific Composting process.
This process has been approved by Pollution Control Boards in Maharashtra, Andhra Pradesh, Tamil Nadu and Maharashtra. There is also a consent from Central Pollution Control Board for this process. There are 16 plants in India who have been quite successfully practicing this process and have also generated sizeable revenue from the sale of Biofertilizer.

2.6 PROCESS MODIFICATIONS IN ALCOHOL FERMENTATION FOR BETTER YIELD
Special features, Performance and Efficiencies of the project based on this process are as follows :
a) Distillery project
Truly continuous fermentation process with yeast recycling
Higher yields yield of 247 ltrs of alcohol per ton of molasses containing 45% F.S. is guaranteed
Lower effluent generation the process generates only 8 to 10 ltrs of effluent per ltr of alcohol produced (as against 14 to 15 ltrs per ltr of alcohol produced in case of other conventional processes)
Yeast recycle In this process, the yeast is efficiently separated and fed back to fermenter. Therefore no fresh yeast is required to add every day. This also avoids loss of sugar due to yeast growth.
Weak beer recycle this unique feature allows higher dissolved solid level in the fermenter broth which not only makes process infection resistant but also reduces water and steam consumption.
Requires only on fermenter and hence very less floor area for the plan
Performance and Efficiencies
The capacity offered will produce min. 81000 lit of spirit (94.68% v/v) per 24 hrs, conforming to IS 323, 1959 grade I. Impure sprit production will not exceed 4050 ltrs per 24 hours. The total spirit production shall be 76950 ltrs per 24 hrs.
Fermentation efficiency will be between 90% and the distillation efficiency will be 98.5%. These efficiencies are based on stable operating conditions and quality of raw material used.
Extra Neutral Alcohol
The ENA produced will be of quality better than IS 6613-1972, specs for neutral spirit for alcoholic drinks. Rectified spirit as per IS 323 Grade I will be the raw material. Re-distillation efficiency will be 98.5%.
Anhydrous Alcohol
It is a mature and reliable technology capable of producing a very dry product. However, its high capital cost, energy consumption, reliance on toxic chemicals like benzene, and sensitivity to feedstock impurities, has virtually eliminated the use of azeotropic distillation in modern ethanol plants. Benzene has been used as entrainer of choice for ethanol dehydration but it is now known to be a powerful carcinogen.
Athani Sugars Limited
EIA/EMP for Expansion of Sugar, Distillery & Cogen Plant in Dist. Belgaun, Karnataka 2-28
Some of the advantages of Molecular sieve technology for ethanol dehydration are as follows:-
The basic process if very simple, making it easy to automate which reduces labour and training requirements,
The process is inert. Since no chemicals are used, there are no material handling or liability problems which might endanger workers,
Molecular sieves can easily process ethanol-containing contaminants, which would cause immediate upset in an azeotropic distillation system. In addition to ethanol, a properly designed sieve can dehydrate a wide variety of other chemicals, thereby providing added flexibility in future operating options,
The molecular sieve desiccant material has a very long potential service life, with failure occurring only due to fouling of the media or by mechanical destruction. A properly designed system should exhibit a desiccant service life in excess of 5 years,
It can be configured to function as a stand-alone system or to be integrated with the distillation system. This lets the customer make the trade-off between maximum operating flexibility versus maximum energy efficiency,
If fully integrated with the distillation system, a steam consumption rate only slightly above the absolute theoretical minimum for the separation can be achieved,
A properly designed molecular sieve can reliably dehydrate 160 proof ethanol to 190 + proof, making strict control of rectifier overhead product quality unnecessary.
Advantages of System:
Minimal Labour.
Stable operation.
Near theoretical recovery.
Steam consumption minimized by multi-stage preheating to permit substantial heat recovery and reuse.
An advanced control system, developed through years of experience, to provide sustained, stable, automatic operation.
Consistent excellent product quality maintain
The AA produced will be of quality 99.8% v/v.
The feedstock quality, ethanol 95% v/v.

CHAPTER 3
DESCRIPTION OF THE ENVIRONMENT
3.1 GENERAL
3.1.1 Sources of environmental data
The baseline information on micro-meteorological data, ambient air quality, water quality, noise levels, soil quality, floristic descriptions and traffic density have been generated by M/s JV Analytical Services, Pune. Long term meteorological data available from the nearest IMD station at Belgaum, about 108 km aerial distance from plant site towards SSW direction. Apart from these, secondary data have been collected from Census Handbook, Revenue Records, Forest Department, etc. The generation of primary data as well as collection of secondary data and information from the site and surroundings was carried out during summer season from March to May 2014. The data was generated after the receipt of the Terms of Reference from Ministry of Environment and Forests in line with the requirements of the MoEF.
3.1.2 Study area
For the description of baseline environmental scenario, the plant area has been considered as the core zone. The area falling within a distance of 10 km from the boundary of the core zone has been considered as the buffer zone. It falls within Maharashtra & Belgaum District of Karnataka. The core zone and the buffer zone, combined together, form the study area for determination of baseline status and for assessment of impacts.
Belgaum district is located in the north-western part of Karnataka state. It is a frontier district of the State and is bounded on the south-west by Goa, on the west north-west and north by the district of the Ratnagiri, Kolhapur and Sangli of Maharashtra State, on the east by Belgaum district, and on the south by the district of Dharwad and Uttar Kannad. It may be incidentally noted that the jurisdiction of this district extends over 2 villages (of Belgaum taluka) which are located a few kilometers away from the district borders.
3.2 TOPOGRAPHY & DRAINAGE
The landscape of Belgaum district mainly consist of vast stretches of plains studded with solitary hills, most of which are flat topped and are adorned with fortifications. The western fringe particularly in the south is at a relatively higher elevations. The district may be divided into four natural divisions. The western belt which is quite narrow, is characterized by rugged terrain. The extreme west is in fact a succession of valleys running between the spurs that stretch out from the Sahyadri range. In this zone, the rainfall is moderate to heavy and the climate is damp and cool and the vegetation is abundant. The northern belt consists of plateau of poor soils and is characterized by a dry climate. Amidst the plains there are some low rolling hills which are generally devoid of tree growth. The banks of the rivers and streams are however flanked with rich black cotton soil. The central belt is separated by the Belgaum hills on the west and further east by succession low sand stone ranges. The Ghatprapha valley which has its origin in the Western Ghat changes here into the waving plains broken by lines of low hills.
Athani Sugars Limited
EIA/EMP for Expansion of Sugar, Distillery & Cogen Plant in Dist. Belgaun, Karnataka 3-2
The southern belt presents a mixed landscape, while the lands of west of Maharashtra valley are covered by rugged hills and forest, the lands in the eastern zone are more open and consist of level ground broken by gentle slopes and an occasional mass of granite. Black cotton soil is the predominant type of soil noticeable in this belt. Towards the east the terrain is broken by low hills on which stand the remnants of old forts. The slopes of most of these hills are covered with brush wood and prickly pear and at several places these slopes have been brought under cultivation as well.
3.2.1 Topography
Core zone: The topography of the proposed plant location area is plain and already having industrial structure. The average elevation of the plant area is 590 m above mean sea level, as seen in google earth. The slope is towards South. The site superimposed on the digitized topographical and drainage map of Survey of India (which cannot be reproduced since it is restricted) is shown in Fig 3.1.
Buffer zone: The topography of the study area is generally plain with less undulation. The general slope in the study area is towards the drainage channels, which are spread out across the study area as seen in Fig 3.2. The elevation of the study area varies between 532 m to 640 m above MSL. The topography of the region is such that it has well developed drainage system. The Digital Elevation Map of 10 km radius is given in Fig 3.3.
3.2.2 Drainage
Core zone: As per the toposheet, no stream is passing or originating from the plant area. There are no water bodies within the plant site area. Rain water run off is through sheet flow from plot area joining the natural drainage.
Buffer zone: There are few water bodies present in the study area. Drainage of the study area is dendritic.
Streams/ Water bodies present in 10 km radius are given in Table 3.1.

Beyond Buffer Zone: The Krishna, the Ghataprabha and the Malalprabha are the principal rivers which flow across the district from west to east and drain the waters in its northern, central and southern tracts respectively. The river, which has a total length of 1400 traverses through the States of Maharashtra, Karnataka and Andhra Pradesh. Within Belgaum district, however, the river flows for a distance of about 70 km only. On entering the district near the north-eastern corner of Yedur village, the river flows south-west and then takes a U turn, receives the waters of the Dudhganga flows from the west and flows eastwards along the southern borders of Yedur, Manjari and Ingali villages of Chikodi taluka. Thereafter, the river forms the natural boundary between the taluks and Athani and Raybag cuts across Athni taluka and the again it forms the natural boundary between Athni taluka and then again it forms the natural boundary between Athni taluk and Jamakhandi taluk of Belgaum district.
3.3 CLIMATE
Belgaum is well known for its pleasant climate throughout the year, but the last few years, summers (April through June) have been warmer than usual. It is at its coldest in winter (November through February), and experiences continuous monsoon of medium intensity during July to September. The annual average rainfall is 50". The climate of Belgaum district is, by and large, quite healthy and agreeable. Within the district, the eastern zone has a dry climate characterized by a hot summer. The Khanapur-Belgaum zone has a more moist climate. The year is usually divided into four seasons.
The period from March to May is reckoned as the summer season and usually April happens to be the hottest month. During this month, the mean maximum temperature reaches 35.7 degrees Celsius and the mean minimum touches 19.5 degrees Celsius. On individual days, at times the mercury touches the mark of 41 degrees Celsius. During May, the oppressive heat is relieved by sharp showers. The rainy season starts during June and lasts till the end of September. During May and June, the nights are warmer than in April. The months of October and November are regarded as the months constituting the post-monsoon season which is noted for heavy fogs and misty mornings. Winter sets in during December and lasts till the end of February. December is the coldest month of the year and on individual days the minimum temperature would be as low as 7 degrees Celsius. This period coincides with the driest part of the year and the skies are usually bright and clear. The data in respect of various parameters are briefly discussed in the following paragraphs.

cent of the annual rainfall precipitates during the south-west monsoon season which lasts from June to September, July happens to be the month with the heaviest downpour. In the western portion of the district the rainfall is reliable and the seasonal conditions are fairly god and are helpful to agriculturists. In the eastern sector, however, the rainfall is not only scarce but also capricious. A redeeming feature is that these tracts are endowed with black soils which have a high moisture-retentive capacity. Furthermore, in these parts, under the Ghataklprabha and the Malaprabha projects, large tracts of lands have, in recent years, been provided with assured canal irrigation facilities. Monthly average rainfall at IMD station Belgaum is given in Table 3.3 and shown in Fig 3.5.

3.5.3 Methodology
Respirable Particulate Matter (PM 10)
The sampling of ambient air was performed with Respirable Dust Sampler, which is primarily a High Volume Sampler fitted with a cyclone separator for pre-separation of particles larger than 10 microns diameter. Air exiting from the separator is drawn at a measured rate through the separator followed by a pre-weighed glass fibre sheet of 20 cm x 25 cm sizes (Whatman, EPM-2000). The RPM concentrations are determined gravimetrically from the average airflow rate, sampling period and the mass of particulate matter collected over the GF filter surface.
Fine Particulate Matter (PM 2.5)
The sampling of ambient air was performed with Fine Particulate Sampler for particles less than 2.5 microns diameter. The PM concentrations are determined gravimetrically from the average airflow rate, sampling period and the mass of particulate matter collected over the PTFE filter surface.
Sulphur dioxide
The sampling of ambient air for evaluating SO2 concentrations was performed with a Multigas Sampler, using the vacuum created by the Respirable Dust Sampler for drawing the air samples through the impingers. Air is drawn at a measured and controlled rate of 300 ml/min through a solution of sodium tetra-chloromercurate.
After completion of the sampling, the used absorbing reagent is treated with dilute solutions of sulfamic acid, formaldehyde and para rosaniline hydrochloride. The absorbance of the intensely coloured para rosaniline methyl sulphonic acid is measured and the amount of SO2 in the sample is computed from graphs prepared with standard solutions. The ambient SO2 concentrations were computed from the amount of SO2 collected and the volume of air sampled.
Oxides of Nitrogen
The sampling of ambient air for evaluating NOx concentrations was performed with a Multigas Sampler, using the vacuum created by the Respirable Dust Sampler for drawing the air samples through the impingers. Air is drawn at a measured and controlled rate of about 300 ml/minute through an orifice-tipped impinger containing solutions of sodium hydroxide and sodium arsenite. After completion of the sampling, an aliquot of the used absorbing solution was treated with solutions of H2O2, sulphanilamide and NEDA. The nitrite ion present in the impinger was calculated from the absorbance of the resulting solution and from the graphs prepared with standard solutions. The ambient NOx concentrations were computed from the total nitrite ion present in the impingers, overall efficiency of the impinger and the procedure, and the volume of air sampled.

Twenty four hour average PM10 level was found to range from 30.2 to 62.3 μg/m3, PM 2.5 was found to vary from 7.5 to 28.6 μg/m3, SO2 from 4.2 to 15.3 μg/m3 and NOx from 5.6 to 20.3 to μg/m3. CO is found to be lower than < 3 μg/m3 at all the locations. All the values are on the lower side at all the locations.
The National Ambient Air Quality Standards dated 18th November 2009, which give the limits for industrial as well as residential & rural area is attached in Annexure VII. Results of monitoring are compared with the standards laid down by Central Pollution Control Board in Table 3.9.

From the above table it can be concluded that the maximum value of ambient air quality monitored in the study area does not exceed the limit laid down by CPCB for all the parameters. The concentrations of SO2 and NOx are considerably low compared to the 80 μg/m3 NAAQS permissible limit for residential, rural and other areas. The concentrations of PM2.5 are within limits of 60 μg/m3 as per National Ambient Air Quality Standard.
One PM 10 sample from the core zone has been analysed for presence of PAH. Particulate laden PAH sample have been collected on Whatman glass fibre filter (EPM 2000) using Respirable Dust Sampler at a flow rate of more than one meter cube per minute for a period of 24 hours. Sample was extracted with toluene using soxhlet extraction apparatus for about 8 hours. Extracted sample was pooled & concentrated using rotary evaporator and analysed on gas chromatograph (GC) using capillary column and flame ionisation detector (FID). The total PAH was found to be below detectable limit.
3.6 WATER RESOURCES
3.6.1 Surface water
The Krishna, the Ghataprabha and the Malalprabha are the principal rivers which flow across the district from west to east and drain the waters in its northern, central and southern tracts respectively.
The Krishna river has its fountain head in the temple of Mahadev at the foot of the steep hills that form the Mahadev range in the range in the Western Ghats north of Mahabaleshvar. In addition to these three major rivers, the district has several small rivers and streams of considerable importance. Markandeya river which rises near Bailur in Khannakpur taluka is an important tributary of the Ghataprabha. Dudhganga which originates in the Western Ghats in joined by Vedganga and finally flows into the Krishan near Yedur.
Athani Sugars Limited
EIA/EMP for Expansion of Sugar, Distillery & Cogen Plant in Dist. Belgaun, Karnataka 3-19
The Sogal stream rises near Sogal in Parasgad taluka, passes through a depression in quartzite ridge and forms what is popularly know as the Sogal Falls before it joins the Malaprabha. Mahadayi is the only west-flowing river of the district. It has its origin near Degaon village of Khanapur taluka, receives the waters of Bhandurnala before it enters the Goa territory, where it assumes the name Mandovi and finally flows into the Arabian Sea. The distance and direction of various water bodies in the study area is already given in Table 3.1.
Flood hazard zonation : A perusal of Fig 3.1 shows that there are only seasonal drainage in around the plant and the nearest Lingnur Minor is at a distance of 6 km from the project site. Krishna river is at a distance of approximately 13 km. Thus, there is no risk of flooding due to inundation of surface streams and river during normal monsoons.
3.6.2 Geology
The rock formations of the district chiefly consist of the Dharwars, gneisses, Kaladgi series and the Deccan trap. The Dharwars are mostly seen in the western parts of Khanapur and also in the taluka of Belgaum and Sampgaon. These rocks are represented by schists, phyllites, quartzites and banded ferrugenours quartzites. The gneissic system consists of different types of granite and gneisses which ultimately give rise to clay. Rock formations belonging to this system are found in the southern parts of the district.
The Kaladgi series are represented by sandstone, quartzite, conglomerates, haematite, dolomite and lime stone. Sandstone and quartzite are particularly noticeable in the taluka of Ramdurg, Parasgad, Gokak and Belgaum in the form of low ridges. The Deccan Traps occupy a major portion of the district, especially in the northern and eastern parts. The chief varieties found here are the basalt, amygdaloid trap, vasicular trap and the clayey trap.
The upper layers of the trap are generally capped by beds of laterite and clay. The economic minerals found in the district include iron, manganese, bauxite, limestone and clay besides sand and stone which too are being commercially exploited.
3.6.3 Hydrogeology
Water table generally follows the topography of the area and is at greater depths in the water divides and topographic highs, but becomes shallower in the valleys and topographic lows and therefore, groundwater moves down and follows the gradient from the higher to lower elevations, that is, from recharge area to discharge area. Therefore, locally direction of flow from higher elevations is towards the rivers. Overall, the general flow direction of ground water in the district is generally towards the east.
The district is underlain by gneisses, schist, limestone, sandstone, basalts, alluvium, etc. of Archaean to Recent age. Deccan basalts cover an area of 7,650 Sq.Kms. in the northern part of the district and have a maximum thickness of around 256 m, which gradually thins out in the southern direction as shown in Fig 3.11.

FIG 3.11: HYDROGEOLOGY IN BELGAUM
(Source: http://cgwb.gov.in/district_profile/karnataka/belgaum_brochure.pdf)
The percentage of safe area in the district is 39.5% and the rest 60.5% is the over exploited area. No area comes under the category of semi-critical or critical stage of development.
In the major parts of the district, the decadal mean of depth to water level generally ranged between 5 to 20 m bgl (Fig 3.12). During pre-monsoon period i.e. May 2014, 8%, 28%, 37%, and 27% of the wells had depth to water level ranges between 0-2, 2-5, 5-10 and 10-20m bgl respectively (Fig 3.13). There was a rise of water level in 30%, 20% and 30% of the wells during post monsoon period i.e. in the range of 0-2, 2-4 and more than 4m respectively.

On the other hand 12%, 5% and 3% of the wells showed a fall in water levels in the ranges of 0-2, 2-4 and more than 4m respectively. Therefore, more than half of the district had depth to water level between 2-5m bgl during post-monsoon period and the overall depth to water level in the district was between 0 to 10m bgl, except in a small strip towards southern part of Ramdurg taluk where it is more than 10m bgl.
The long-term pre-monsoon water level trend (1996-2010) shows a rise in 53% of the wells, while there is a fall in 47% of the wells. On the other hand during post-monsoon period, 68% of the wells show falling trend, while there is a rising trend in 32% of the wells. Over all the annualised trend shows a fall in 61% of the wells and rise in 39% of the wells.
Belgaum District can be categorized as a low to moderately yielding area (1000 lph to 8000 lph) 72.2% of district falling in this category. From considerable part of the district (9%) poor yielding (less than 1000 lph sources) or non feasible areas have been reported. The talukas having largest poor yielding area, are Muddebihal (19%) followed by Indi (15%), Belgaum and sindagi (13% each), Basavan Bagewadi (4%). Low yielding areas (1000lph to 4000lph source) in the district constitute about 40% of the district, with the largest being Basavan Bagewadi (54%) and smallest in Indi taluka Moderate yields (4000 lph to 8000 lph source ) are reported from 36% of the district, highest being in Belgaum with 70% of the area, and lowest being in Sindagi with 19% of the taluka. High yielding areas (more than 8000 lph sources) over 15% of the district. The smallest area under this category are in Sindagi Taluka (2% each) and largest is in muddebihal (29% each) where very lengthy contact zones occurs between traps and other formations.
The ground water recharge potential in the area has been estimated by using rainfall-infiltration and water table fluctuation methods.
A. By rainfall infiltration method
Total study area - 438.47 Sq.km. Annual Average Rainfall (IMD Belgaum 1961-1990)
- 1330.8 mm
Rainfall infiltration index as per GEC recommendation for alluvial area (Areas with higher clay content)
- 15%
Monsoon groundwater recharge - 87.52 MCM
B. By water table fluctuation method
Total study area - 438.47 Sq.km Average seasonal change of water table - 4 m Specific yield - 5%Monsoon groundwater recharge - 87.69 MCM
As per the recommendations on ground water resource estimation methodology, if the difference between the above two, expressed as a percentage of the rainfall infiltration method, is greater than or equal to -20%, and less than or equal to +20%, then the recharge is taken as the value estimated by the water table fluctuation method. If it is less than -20%, then it is taken as 0.8 times the value estimated by the rainfall infiltration factor

method. If it is greater than +20%, then recharge is taken as equal to 1.2 times the value estimated by the rainfall infiltration factor method.
The difference between the two is 0.2%, thus, recharge is taken as the value estimated by the water table fluctuation method. Thus, 87.69 MCM per annum is the estimated annual ground water resource.
Ground water use There are three major consumer of ground water in the area (i) Domestic (ii) Irrigation (iii) Livestock. The ground water use by the three users is worked out as under
A. Domestic
Total population as per Census 2011 - 105413
Per capita domestic need - 70 LPD
Total annual ground water use - 2.69 MCM
B. Irrigation
Total area irrigated by ground water - 11330.91 Ha
Gross irrigation (50 cm/ha) - 5665.4 ha m
Annual consumption - 56.65 MCM
Ground water is used for 6353.24 ha i.e. 56.07% of irrigation, thus, ground water used for irrigation is i.e. 31.76 MCM.
C. Livestock
The water consumption for livestock has been empirically considered as 5% of human consumption, which comes to 0.13 MCM.

3.8 TRAFFIC DENSITY
3.8.1 Monitoring locations
A traffic density survey was conducted round the clock from 19-20.04.2014 on Purshottam Road at a distance of about 2.0 km, S from the project site. The traffic monitoring station is shown in Fig 3.10.
3.8.2 Methodology
Traffic density measurements were made continuously for 24 hours by visual observation and counting of vehicles under four categories, viz., heavy motor vehicles, light motor vehicles, two/three wheelers and others. As traffic density on the road is low, one skilled person was deployed simultaneously during each shift for counting the traffic. At the end of each hour, fresh counting and recording was undertaken. Thus, the total number of vehicles per hour under the four categories was determined.
3.8.3 Observations

3.10 SOIL QUALITY
3.10.1 Soil of Belgaum District
The district is occupied by three types of soils viz. Black soils, Red sandy soils and mixed soils. Formation of various types of soils is a complex function of chemical weathering of bedrocks, vegetative decay and circulation of precipitated water. Soils are mostly in situ in nature.
Black soils are derived from basaltic bedrock. These soils in upland areas are shallower and are deeper in valley portions. The Don River valley has plains and consisting of rich tracks of deep black cotton soils stretching from west to east in the central part of the district. The infiltration characteristics are poor to moderate. The constant rate of infiltration in these soils varies from 0.75 to 2.5 cm/hr. These soils are alkaline in nature, low in potassium and nitrogen.
Black cotton soils with high clay and humus content in low-lying areas. They have high moisture holding capacity and on drying up these soils develop open cracks.
Red soils, which are sandy in nature derived from granites, gneisses and sandstones, are found in southern part of Muddebial taluk of the district. The infiltration rates of these soils range from 2.6 to 3.8 cm/hr.
Mixed soils are derived from the fringe areas of Deccan traps and granites, gneisses, limestones and sandstones in Muddebial and Basavana Bagewadi taluks of Belgaum district. These are dark greyish brown and dark brown to dark reddish brown in colour. Their texture varies from loam to clay. The infiltration characteristics of these soils are moderate to good in nature.
Black soils constitute 90% of the area with 400,000 ha of medium black soils, 262,000 ha of shallow black soils and 234,000 ha deep black soils.

3.11 ECOLOGY
An ecological assessment was conducted in and around the proposed site for assessing the diversity pattern of the floral species. Faunistic pattern of the area was studied based on inquiries from the local population, personal observation and forest officials.
The specific aims of the Ecological Assessment component are to provide: Account of the Flora and Fauna types present within the project area and within 10
km radius of buffer zone, including significance status under The Wildlife (Protection) Act, 1972, if necessary, recommendations for conservation plan for Schedule I species;
Evaluation and comment on the presence or absence of any at-risk, migratory or otherwise significant species of flora and fauna of the area;
Assessment and comment on any significant habitats within the project site, including their contribution to faunal movement corridors;
3.11.1 Flora
The vegetation of Belgaum district is of two types. The moist occurs in the south-western portion where the district touches the crest line of the western ghats. The second, found towards the east of Belgaum city stretches from the northern areas around Athani, Chikodi and Gokak right down to Sampagaon and Saundatti in the south. It is of the dry type.
The moist vegetation is sustained by the heavy seasonal precipitation from the south-west monsoon which is active from June to October. The duration of the monsoon decreases from south to north. As there is a long dry spell from late October to early June the plant cover has to survive despite the rainless period.
Natural moist forests in Belgaum district have felt the pressure of over exploitation especially in recent years. The natural vegetation has been replaced by forest plantations. The eastern part of the district is crossed by three main rivers, the Krishna, the Ghataprabha & the Malaprabha. Ridges of sandstone hills separate the three river basins. It is mostly on these hills that remnants of the native flora continue to survive. Dry forest is made up of small trees, mostly slow growing, with either broad or reduced leaves. Similarly there are no important medicinal plants that are uncommon to other areas.
(a) Flora in core zone
In the project area, sugarcane is grown. Besides this plantation of trees such as Mango, Neem, Karanj, Gulmohar, Kaner etc. are also done in the project area.
(b) Flora in buffer zone
In the study area trees like Mango, Ashok, Coconut, Cassia, Gulmohar etc. are commonly observed. The ecological study was undertaken to understand the present status of ecosystem of the area, to predict changes as a result of proposed activities and to suggest measures for maintaining the conditions. This was carried through secondary data collected from various Govt. agencies like Forest Department, Agriculture Department etc.
Athani Sugars Limited
EIA/EMP for Expansion of Sugar, Distillery & Cogen Plant in Dist. Belgaun, Karnataka 3-35
As the plants are static, they have been identified based on their specific diagonistic characters of Family, Genus and Species using available floral, other related literature and herbarium Botanical Survey of India.
Besides the collection of plant species, information is collected on the vernacular names and uses of plants made by local inhabitants.
Qualitative analysis of vegetation is made by floristic method (by simple studying various genera and species of various plant groups i.e. herbs, shrubs, trees and climbers etc).
List of flora in the buffer zone is given in Table 3.19.

Economically important Flora of the study area
Agricultural crops: There are 25% irrigation facility in the area and the agriculture in the area is predominantly rain fed- 66%. The principal agricultural crop is Paddy. But other crops like maize and vegetables are also grown in pockets, where water is available for irrigation. Sugarcane is the preferred crop around sugar mill. The soil is mostly red.
Minor forest produce: Most of the population depends on the forest for raw material for their traditional occupation apart from fodder, honey and wood. There is less modern cooking energy source and the villagers mainly depend on fuel wood.
Medicinal plant species: The nearby area is also endowed with several medicinal plants which are commonly available in the shrub forest and waste lands. The common medicinal plants of the region are Eucalyptus globulus (Nilgiri), Ocimum basilicum (Ban Tulsi), etc.
Fuel wood plant species: Forest is a major source of fuel wood for the local villagers. They use to collect dry leaves, stems and log to fulfill their daily need for fuel wood requirement. Polyalthia longifolia (Ashok), Mangifera indica (Mango) etc. are the species used for fuel wood collection from the surrounding forest area.
Rare and endangered floral species: During the vegetation survey of both core zone and buffer zones of the plant area did not encounter any such species which are endangered or threatened under IUCN (International Union for Conservation of Nature and Natural resources) guidelines.
Vegetation in the hamlets: The species composition near the hamlets is different from those found in the natural environmental conditions. The vegetation structure surrounding the hamlets reflects a typical character of habitation. The trees in the settlement area are catering to the needs of local population such as fodder, fuel-wood, fruit, and timber and for religious purposes. Some of the common species found in the hamlets comprise Mangifera indica, Ficus religiosa, Zizyphus jujuba etc.
3.11.2 Forests
There is no forest in the core zone. There is no National Park/ Wildlife Sanctuary/ Tiger Reserve within 10 km radius of proposed plant site. The nearest National Park is Bhagwan Mahavir National Park at a distance of 176 km, SSW and nearest Wildlife sanctuary is Ghataprabha at a distance of 105 km, SSW from the project Site.
Athani Sugars Limited
EIA/EMP for Expansion of Sugar, Distillery & Cogen Plant in Dist. Belgaun, Karnataka 3-37
Classification of Forest Types study has been observed as sub group 3C/C2 as Sal bearing forest under the major sub group 3C as Tropical Dry Deciduous Forest. Forests within revenue villages account for only 0.31% of the study area. There is only one Reserve Forest at a distance of 13.0 km, NNW within the study area.
Cultivation crops
In Athani agricuture is the main occupation the main crops are Jawar, Wheat, Sunflower, toordal, kushbi, etc are cultivated. The commercial crops are grapes, cotton are cultivated here the main commercial crop is Sugarcane. Most of the farmers cultivates Sugarcane. Athani is one of largest sugarcane cultivation taluk in Karnataka Irrigation facilities of Hipparagi berrage of Upper krishna project is their in Athani taluk. It is very helpful for cultivation sugarcane and grapes. The most part of taluk is fertile land. By Hipparagi project there were canals constructed in Athani which are useful for agriculture.
Belgaum district as such was described as cultivated area from the view of agricultural. At the beginning the crops like, Jawar, Wheat, Bajara, Groundnut, Chilli, were grown. Due to availability of river water the sugarcane growers increased to the large extent. The survey conducted in the project area indicated that there is no competing crop for sugarcane. High value crops like chillies, fruits and vegetables are grown in few villages. However, area under these crops is very meager. Jawar, wheat, bajra, safflower, sunflower and groundnut are other important crops that provide a source of income. Farmers reported that they are not happy with private traders about the payment received and the price offered to them for these products. Moreover, there is an certainty of the payment from traders and is generally delayed. In case of sugarcane, the first installment is assured within the first 15 days from the date of sugar cane supplied to the sugar factory. Farmers also feel that soyabean, jawar, groundnut, sunflower and wheat fetch less income as compared to sugarcane. Soyabean and groundnut crops are also affected due to rains during September and late August. Moreover, in spite of adopting recommended package of practices, the entire crop is lost most of the time leading to loss of income. The agro- climatic conditions and soil type prevailing in the operational area of ASL are very much congenial for healthy growth of good quality sugarcane. Sufficient irrigation facility is also available from irrigation Schemes as well as tube wells existing in the area. Water level of existing wells are reportedly increased because of regular monsoon during past few years and hence there is considerable scope to improve the cultivation practices and shift over to sugarcane. It is also observed that cultivators in command area are progressive and are aware of sugarcane cultivation practices. In view of above, local farmers other crops wish to switch over to sugarcane cultivation.

CHAPTER 4
ANTICIPATED ENVIRONMENTAL IMPACTS & MITIGATION MEASURES
4.1 GENERAL ASPECTS
Environment management plan has been prepared for the proposed Sugar plant expansion from 4500 to 12000 TCD, Distillery plant Expansion from 60 to 90 KLPD and Cogeneration plant expansion from 24 to 54 MW at Vishnuanna Nagar, Post- Navalihal, Tal. Athani, Dist Belgaum, Karnataka as per the EIA Notification 2006 issued by Ministry of Environment & Forests, Government of India. The plant will have an impact on land, air, water, noise, soil, ecology, socio-economics, etc.
The environment management plan includes the evaluation of total impacts after superimposing the project activities over base line data. This helps in incorporating proper mitigation measures wherever necessary for preventing deterioration in environmental quality. Keeping in mind the environmental baseline scenario as detailed in Chapter 3 and the proposed project activities described in Chapter 2, it is attempted to assess the likely impact and its extent on various environmental parameters in this chapter.
The important environmental parameters likely to be affected due to industrial projects and which have been incorporated into this chapter are as follows:
- Topography and drainage
- Climate
- Air environment
- Noise environment
- Traffic density
- Water environment
- Land environment
- Solid waste
- Ecology
- Socio-economic environment
- Occupational health and safety
- Other industries
Athani Sugars Ltd.
EIA/EMP for Expansion of Sugar, Distillery & Cogen Plant in Dist. Belgaun, Karnataka 4-2
- Places of archaelogical, religious or tourist interest
The beneficial impacts anticipated from an industrial project, irrespective of their relevance to the proposed project, would be the employment opportunity available.
4.2 TOPOGRAPHY AND DRAINAGE
4.2.1 Topography - impact & mitigation
Impact: The topography of the proposed site is plane with gentle slope and slightly undulation. The agriculture land was converted to industrial purpose at the first stage of installation of the plant.Thereafter an expansion was undertaken and currently a second expansion is proposed in this report in the same premises and area. Thus, no significant changes in topography in the core zone are anticipated since majority of the construction of the buildings such as walls, buildings, stock yards etc. have already occurred. The ground has already achieved a requisite level during previous construction phases. There will be no impact on topography of the buffer zone.
Management: The additional change in topography in the core zone will not lead to additional changes in the sheet flow pattern of rain water within the core zone since most of the construction has been carried out in the previous phases of construction. Moreover, a network of planned storm water drainage is provided and maintained. The additional construction is expected to be completed in one year.
4.2.2 Drainage - impact & mitigation
Impact: The nearest water body from project site is Lingnur Minor at distance of 6 km in North West Direction. As no stream or water body is traversing through or originating from the plant site area, therefore no impact on stream flow will be there due to the project. As discussed in the section related to topography, the sheet flow of rain water shall not get additionally affected within the core zone since most installations & buildings are already existing. As the sheet flow runoff from plant site is going into natural drain at present, there will be marginal change in the volume of flow as some of the water from the plant area will get captured and harvested and recharged to ground.
Impact on the drainage in the buffer zone is not anticipated as no construction will be taking place outside plant boundary.
Management: As explained in topography, the sheet flow will be managed through the storm water drainage. Rain water Harvesting will be carried out to reduce the load on fresh water uptake from river. It will also recharge & raise the ground water table.

4.3 CLIMATE
4.3.1 Impact on climate
The climatic conditions including temperature variations, wind direction and speed, rainfall and humidity are governed by regional factors and the monsoons. As such plant operations and other allied activities will not tend to influence the climate. Further, carbon dioxide (green house gas) contributing fuel in the form of bagasse in boilers will be used and diesel to operate the trucks and tractors, which will be a necessity.
During the construction phase, the activities will be restricted to construction of additional buildings and erection of structures, plants and machinery. Due to the existing & proposed construction of buildings, an urban heat island effect will get created locally which raises the temperature at the buildings and its immediate vicinity.
The major impact on global scenario of climate change will be in terms of contribution of carbon dioxide into the atmosphere during operation. Carbon dioxide is formed due to combustion of the bagasse which contains carbon and releases CO2 as a combustion product.
In case of cogen plant, the carbon dioxide emissions are a global concern since it is a green house gas (GHG). The CO2 emissions anticipated per MWH of energy has been calculated as follows:
For 54 MW X 330 days X 24 hours = 4,27,680 MWH energy, bagasse required is 576000 MTPA
For 1 MWH energy, bagasse required is 1.35 T.
Based on the techno economic feasibility report of proposed Plant, the analysis of bagasse fixed carbon is 22.7%. One tonne of bagasse contains 227 kg of carbon. Therefore, 1.35 T contains 306.45 kgs of carbon
Molecular weight of carbon = 12 and of CO2=44
Hence, for generating 1 MWH energy, CO2 emitted = 1306.45 X 44/12 = 1123.65 kg or 1.12 T/MWH
As such, there is no viable and feasible technology to sequester this CO2 at present although pilot research projects have been undertaken in China and Europe. However, research underway across the world and any such technology available in the future shall be taken up. Plantation is a suitable method to sequester carbon and 48 acres of plantation has been carried out outside the plant area.

EIA/EMP for Expansion of Sugar, Distillery & Cogen Plant in Dist. Belgaun, Karnataka 4-4
4.3.2 Mitigation measures
The operations are to be carried out in a limited area, as a result no large scale climatological impacts are anticipated. Development of greenbelt in the plant area will contribute in a positive manner towards mitigation of greenhouse gases as well as reducing temperature due to the urban heat island effect. Global warming is a global concern and hence, the company will be undertaking all possible measures to minimise the CO2 emissions. Since part of the transportation is through trucks, it will be ensured that the vehcertificates. The trucks will be maintained in order to ensure optimum fuel utilization.
Urban heat island can be reduced by using environment friendly building material. Plantation of trees, low heat gain layouts of the buildings and creation of shades and water bodies over which wind can blow to cool down, are some measures to reduce the impact of urban heat island effect.
4.3.3 Micro climate
In the project site, the micro climate at different parts of the plot will not be same. The area of green belt will be cooler than the infrastructure area and remaining part of the plant. The boiler and associated area will be hotter as compared to other areas of the plant. The storage yard for the cane would have warm and humid climate. The emission sources like stack will also be hot due to release of gases.
Micro-climate modification involves the best use of structural and landscape design elements to maximize or limit sunlight, shade and air movement. Structural modifications involve the design of the building and associated construction (driveway, walkways, fences, etc). Landscape modifications involve the use of plants to further increase or decrease the impact of sun and wind upon the local environment. This will decrease the energy costs associated with maintaining interior comfort. These are components of building design and as such have been incorporated in the architecture and layout of the plant & buildings passively.
4.4 AIR ENVIRONMENT
4.4.1 Impact on air quality
A. Construction Phase
Sources of air pollution, during the construction phase will be:
- Vehicle exhausts for transport of materials
- Dust generation during construction due to excavation work, shifting of construction materials (cement, sand and gravel), vehicle movement on unpaved roads and concrete preparation plant.
- Exhaust from construction equipment like compressors, DG sets, etc.
Primary impact from these sources on air quality will be high dust generation resulting into increased SPM levels in the surrounding areas. Possibility of
Athani Sugars Ltd.
EIA/EMP for Expansion of Sugar, Distillery & Cogen Plant in Dist. Belgaun, Karnataka 4-5
impairment of visibility of the dust may arise if control measures are not implemented. Further movement of construction equipment for these operations as well as for transport of material will lead to increased level of SPM, SO2, NOx and CO in the surrounding areas. Thus, adverse impacts on air quality are envisaged. The secondary impacts of air emissions dust as well as other emission will be the effect on the health of the labour force working in close vicinity. Secondary impacts of air emission could also effect the flora, crops and nearby residents due to dust deposition, if proper control measures are not adopted.
B. Operation Phase
The project has air pollution point source in the form of boiler stack. The air environment gets polluted due to emission of suspended particulate matter having particle size less than 50 microns. It can also affect the crops grown in the nearby areas. So it can have negative impact on the health of people.
Due to existing state highways & less distances for carts, tractors & trucks to reach mill site the suspended particulate matter generation is anticipated to be within specified limits.
During operation phase, emissions from various types of industries vary from one another in terms of quality and quantity of emissions, production capacity of the plant, type of fuel used, type and complexity of the process employed, use of air pollution control measures and degree of maintenance enforced. The cogen power generation will be proposed to expand capacity. Presently 24 MW power generation exist at the plant, the fuel for boiler is bagasse it requires 2,16,000 TPA. The proposed cogen power project is planned to be implemented as 54 MW, bagasse requirement for proposed unit is 3,60,000 TPA. Total requirement for bagasse for plant is 5,76,000 TPA. This cogen project meets the heat & power needs of ASL and exports balance power to the grid.
i. Air Emissions from Cogen plant
Air quality modeling has been carried out for both existing and proposed scenarios. The major pollutant from the activity is PM. In the present study, the major source has been considered as the stack attached to boiler. The estimation of emission rates based on rate of fuel consumption and characteristics has been calculated. Also, the meteorological data at the site has been collected during study period. After calculation and collection of data, assessment of impact on ambient air quality using ISCST3 model of USEPA for emissions from existing 24 MW power plant and proposed 54 MW power plant have been carried out. The bagasse is used as fuel in the plant.

ii. Transportation
As a matter of fact of Co-generation Power Plant does not invite heavy vehicular traffic at the site, however due to sugar production activities at ASL, there will be an increase in the traffic to and from the site. Vehicles used for transportation of sugar cane as well as finished product would be a bullock cart, Tractors and Trucks where as, utility vehicles used for various purposes would be buses, Jeeps, cars and cycles. The transportation route will be the highway and the connecting road from the highway to the plant for the purpose of the evacuation of sugar while the bullock carts will bring raw material (cane) through internal roads of ASL and village roads from nearby fields.
All trucks proposed to be used for transportation will be covered with tarpaulin, maintained, optimally loaded and have PUC certificates.
In order to predict the possible impacts of vehicular transportation, CALINE4 model has been used. It is based on the Gaussian diffusion equation and employs a mixing zone concept to characterize pollutant dispersion over the roadway. The purpose of the model is to assess air quality impacts near transportation facilities. Given source strength, meteorology and site geometry, CALINE4 can predict pollutant concentrations for receptors located within 500 meters of the roadway. In addition to predicting concentrations of relatively inert pollutants such as carbon monoxide (CO), the model can predict nitrogen dioxide (NO2) and suspended particle concentrations. It also has special options for modeling air quality near intersections, street canyons and parking facilities. The findings of the predicted incremental cumulative impact are given in Table 4.4. The detailed calculations, assumptions and results are given in Annexure XVI.

It can be seen that the resultant GLCs will remain within the stipulated norms after expansion of the plants. The operation of the proposed DG set during emergency will release emissions into air, however, they will be low concentration and temporary.
4.4.2 Mitigation measures
A. Construction phase
During construction phase certain mitigating measures need to be adopted to reduce the primary impact on air environment to the minimum. Water spraying on material to be handled before beginning work and spraying on unpaved surfaces twice a day will improve the working conditions and minimise dust pollution. The designated areas for roads and parking spaces shall be black topped at the earliest. Welding operations shall be carried out within cordoned areas.
During dry weather condition, the dust created by excavation, leveling and transportation activities will be easily controllable by sprinkling of water. Construction equipment and transport vehicle will be maintained properly to minimize source emissions and spillage. Regular maintenance schedule will be adopted.
As per AP-42 of US EPA, the recommended measures for various activities during construction phase are summarised in Table 4.5.

B. Operation Phase During operation phase assessment the mitigation of air pollution emissions and their control are outlined below:
The only major source of air pollution from the ASL manufacturing process is emission from stack attached to boilers used for steam generation and subsequently power. However, has chimney of 3.5 diameter up to 75 m height and the stack height designed on the basis of CPCB guidelines to ensure proper disposal of gas emissions.
Fugitive emissions from raw material storage yards, loading and unloading operations, will be controlled water sprinkling system, if applicable.
Electrostatic precipitator (ESP) will be provided in the additional boiler stack.
Water sprinkling system will also be provided in strategic area for control of fugitive emissions.
Use of bullock carts, which are environmental friendly, for transportation of sugarcane from the villages to the plant site as far as possible.
Ensure that all vehicles (trucks & tractors) used in transportation have PUC Certificate.
As far as possible all internal roads shall be constructed as tar roads and regular water sprinkling shall be carried out on all the kucha roads for preventing fugitive dust emissions.
Construction of speed breakers on roads at regular intervals all over the plant area and / or attachment of speed locking system to the accelerators of all vehicles used for maintaining a speed limit of 20 km/h.Construction of vehicle parking area having at least brick on edge flooring.
No overloading of trucks used in transporting sugar from the plant.
Carry out tree plantation around plant area for minimizing environmental impacts of the proposed activities over a period of time. Plantation program shall be designed and a budget should be allocated for this purpose every year. 33% of the area owned by ASL is planned for greening.
Moreover, the garden development and tree plantation activities of ASL during operational face would ensure minimal impact of fugitive dust emissions.
In addition to above, ASL promised to maintain good house-keeping in all the departments of their sugar manufacturing and power generation departments in order to keep the entire complex clean and free of dust.

During Construction phase: Noise levels in the vicinity of any construction activity increase due to running of bull-dozers, excavators, transport vehicles, pile drivers, portable generators, mechanical machinery such as cranes, riveting machines, hammering etc. These activities will run round the clock. Noise pollution thus

created, particularly during the night, could affect the human habitation. The primary impact of noise level would be mainly on workers engaged on high noise generating machines.
During operation phase: The noise levels near the sources such as Sugarcane cutting, Crushing, Lime addition, Clarification, Evaporation, Sugar separation, Steam Production, Noise making Equipments such as cutters, crushers, mixers, pumps, boilers etc. will be higher. The traffic involved for transportation of raw material and finished product by road will also cause noise pollution and affect habitation along the roads.
The noise levels at machinery sources are anticipated to go as high as 100-105 dB(A) based on experience of similar plants. The general noise levels within core zone are expected to remain below 75 dB(A).
Noise propagation have been studied by mathematical model and impacts of noise on surrounding area have been brought out below. As the equipment generate noise generally not higher than 100 dB(A) at source it can be safely assumed that the ambient noise levels on any point of boundary line of the plant are not higher than 100 dB(A). It has, also been assumed that the area within the core zone within an imaginary line running at a distance of 3-5 m (say) from noise generating machines will be termed as point noise source to avoid complication in the absence of availability of exact location of various noise generating units, their arrangements and shapes. Taking extreme case of two machines each generating 100 dB(A) working at a point will add upto 103 dB(A) overall noise level. Such source noise level has been considered here for anticipating the impacts. Noise attenuation with distance in all directions over flat open bare ground is given by
Sound level dB(A) = Lw 20 log r2/r1
Where : LW = Sound level of source, dB(A) assumed 100 dB(A) r1,r2 = distance from source(m)
The same has been plotted in Fig 4.4. Assuming source noise level as 103 dB(A)
FIG 4.4: NOISE ATTENUATION WITH DISTANCE IN ALL DIRECTIONS OVER FLAT OPEN BARE GROUND
Athani Sugars Ltd.
EIA/EMP for Expansion of Sugar, Distillery & Cogen Plant in Dist. Belgaun, Karnataka 4-14
A perusal of graph shows that the sound levels attenuate to value as shown in Table4.6.
TABLE 4.6 NOISE ATTENUATION WITH DISTANCE ON FLAT BARE GROUND WITHOUT
AND WITH GREEN BELT COMBINED NOISE OF MORE THAN ONE SOURCE = 103 dB(A)
Distance from source (m)
Noise level reduced from 103 dB(A) Without green belt, dB(A) With green belt, dB(A)
20 70.0 68.5 60 60.0 55.5
100 56.0 49.0 150 52.0 41.0 180 50.0 33.0 300 45.0 <33.0
It means that after distance of about 300 m, the machine noise will merge into the background noise in the day time average around 45 dB(A). This noise level is same as the limit [ 45 dB(A) ] prescribed by GSR 742 (E) dt. 30th August 1990 at night time for residential areas. With plantation around the plant site, it will be possible to further lower the noise levels below the prescribed limits. It may be noted that the combined noise from all the three plants cannot be more than 103 dB(A) at any point considering the distance between their relative locations.
Several noise suppression and attenuation features shall be designed in the plant for the protection of personnel at all normally accessible locations within the plant boundary, both inside and outside different buildings, and for the protection of the inhabitants living in the vicinity of the plant.
The damage risk criteria as enforced by OSHA and CPCB to reduce hearing loss, stipulates the noise levels up to 90 dB(A) as acceptable limits for 8 hour working shift per day. Noise levels may, however, exceed the prescribed limits in certain work places. At these work places, workers will be posted for shorter durations only. Operations and maintenance personnel will not be exposed to the high levels for reasons of the control operations conducted from sealed cabins. The OSHA damage risk criteria are reproduced in Annexure XI and the Ambient Air Quality Standard in respect of noise is given in Annexure X. 4.5.2 Mitigation measures
The following measures will be taken up to keep the noise levels with in permissible limits:
a. Provision and maintenance of green belt. The proposed green belt will also help to prevent noise generated within the plant from spreading beyond the plant boundary.
b. Proper maintenance of noise generating machinery including transportation vehicles
Athani Sugars Ltd.
EIA/EMP for Expansion of Sugar, Distillery & Cogen Plant in Dist. Belgaun, Karnataka 4-15
c. The noise generation will be reduced at source by erecting noise dampening enclosures, by maintaining the machines and greasing them regularly.
d. Provision of air silencers to modulate the noise generated by the machines/equipments
e. The equipments will be provided with acoustic shields or enclosures to limit the sound level inside the plant.
f. Provision made for special vibration dampness and monitoring to prevent propagation of vibration to surrounding areas.
g. Use rubber packing in the foundations of machineries to prevent noise transmission to the surrounding.
h. Noise from safety valves, start up vents, steam jet ejectors of condenser etc. will be reduced by providing silencers at the outlet of down steam piping.
i. All the workers engaged at and around high noise generating sources will be provided with ear protection devices like ear mufflers/plugs. Their place of attending the work will be changed regularly so as to reduce their exposure duration to high levels. They will be regularly subjected to medical check-up for detecting any adverse impact on the ears.Proper encasement of noise generating sources to control noise level. Besides, ear muffs/plugs provided to the workers in the close vicinity of noise source.
4.6 TRAFFIC DENSITY
4.6.1 Impact on traffic density
Incoming raw material is sugarcane only, grown in the adjoining area of the plant. These plantations are owned by the company itself and hence, no public road will be used to transfer the sugarcane from the field to the plant. The transportation shall be carried out by bullock cart. If case of any shortfall, due to unforeseen circumstance, it will be fulfilled from nearby farms using bullock carts. Hence, additional impact on air due to vehicular emission for incoming raw material is not anticipated.
However, there will be increase in trucks, tractors as well as bullock carts due to the evacuation of sugar. The pathway of transportation is given in Annexure XVI. The additional peak traffic load anticipated is 50 trucks per hours and 42 tractors per hour on a peak work day besides bullock carts whose numbers will vary due to varying individual carrying capacity. The bullock carts are anticipated to transport 3000 TPD. Impacts on Air Quality due to vehicle transportation is already given in Table 4.4above, which shows that increase in number of trucks and tractors would lead to increase in the concentration of pollutants at ground level, however, on adding to the existing highest concentrations observed in study area, the resultant GLCs still shall remain within permissible limits.

4.7 WATER ENVIRONMENT
4.7.1 Impact
A. Construction Phase
During construction phase the requirement of water will be on account of concrete mixing, curing and tank preparation, usage in sprays and sprinklers for dust suppression, irrigation for plantation and for landscaping with decorative plants and lawns. During construction hardly 35 m3 water will be required for curing. The construction activity will not have any effect on ground as well as surface water.Even the domestic waste water generated in the labour camp is also very low. The fresh water requirement during the construction phase will be procured from nearby water sources. There shall be approximately 80 workers requiring 15 l/capita/day i.e. 1.2 KLD. It is assumed about 50% of the labour will stay at site in temporary structures and with both parents working and two children, a family of four would require 160 X 135 = 21.6 KLD. Thus, daily construction phase domestic water requirement shall be to the tune of 22.8 KLD.
B. Operation Phase
The plant will derive its water from the Krishna River, which is located at distance of about 13 km. The water requirement will be increased from 850 cum/day to 1298 cum/day after expansion for sugar plant. However, total water requirement on annual basis will be reducing by 22.78% from 245360 KL/A to 189472 KL/A. Necessary

pumping and piping system has been installed for water withdrawal from the proposed source. Water will be stored in a surface water reservoir for the plant and in an overhead (OH) tank for potable purposes. The copy of the water withdrawal permission is given in Annexure XVII. This raw water will be used as a make up for the losses in the process steam, boiler blow down, auxiliary cooling tower blow down, service water, etc. As the sugar plant is an already operating unit, the complete raw water supply system from the reservoir to the sugar mill already exists. After expansion, ASL will need 4268 KLD of water during season and 2337.6 KLD during off-season to fulfill the needs of mill, distillery & co-generation plant, residential colony. Out of this, the fresh water requirement of 448 KLD during season and 1472.6 KLD during off-season shall be drawn from River Krishna, while the rest shall be recycled water from evaporator condensate of Sugar and distillery units. Air Cooled Condenser has been proposed, hence, the water requirement for Cogen Plant is also going to reduce. The spent wash generated shall be 720 KLD then fed to Biodigester for biomethanazation followed by evaporation( seven effect) to reduce and concentrate biomethanated spent wash to 180 KLD . This spent wash is further bio methanated send to seven effect multiple Evaporator and then converted to bio compost using press mud available from the sugar factory. Hence impact on surface and ground water is negligible as zero discharge scheme is planned. Septic tank has been provided to treat domestic effluent. Treated effluent will be used for green belt development, sprinkling, etc. Currently 500 employees are working in sugar factory and 300 employees need for expansion plant. Accommodation is available in total of 140 rooms, out of which 100 rooms are for family and 40 rooms for bachelors. The domestic requirement shall be approximately 73 cum of fresh water per day. Septic tank and soaking pit provided to treat the domestic waste generated from colony. Sources of waste water: During operation of power plant, there shall be various effluents. Acidic and alkaline effluents will be generated during regeneration of various ion exchange units in the RO water plant. Cooling water system for auxiliary circuit operates in a closed cycle with a cooling tower for heat rejection. In order to keep the concentration of dissolved solids within the limits a blow down is maintained from the system. For inhibition of corrosion/ scaling in the circulating cooling water system, a chemical treatment system for dozing of inhibiting chemical shall be provided. Since waste waters from plant are proposed for reutilisation within plant for sprinkling and irrigation, no discharge is anticipated from the plant premises to outside on normal working days. Hence, no impact is envisaged on the surface water bodies and on the fresh water eco-system and ground water.

4.7.2 Impact of drawl of water on the nearby River during lean season
The lean season for Krishna river is in the month of May. However, sugar factory crushing season is closed in the April end. The other unit like distillery which is running requires only 534.8 m3/day drawl of water. For cogen 937.6 m3/day water is required. During the lean season Krishna river is never dried as it is perennial and the water flow in the river near drawl point always more than 5 cum per secs (0.432 MCD). Hence there is no significant impact on drawl of water during April and May month i.e. lean season since the total water withdrawal of 1472.4 cum/day is 0.34 % of the total flow.
4.7.3 Mitigation measures
A. Construction Phase
Waste water generated during construction is insignificant. Proper sanitation facility will be provided with septic tank so that there will be no negative impact on water.
B. Operation Phase
(i) Sugar Mill
Wastewater from Sugar mill will not have significant BOD/ COD levels. All waste water will be collected in effluent treatment chambers and neutralized prior to discharge in the existing sugar plants. The treatment scheme incorporates Aerobic treatment method for the wastewater with state of the art Bio-Aeration Technologies. The flow diagram of the ETP is given in Fig 4.5. In sugar mill maximum due water conservation will be achieved with precise equipment selection.
(ii) Cogen plant
In co-generation also precise design parameters will enhance target of water conservation & power production. Maximum attention is paid to recycle the water in each unit/equipment.

(iii) Distillery
Single stage evaporation technology during alcohol concentration & recovery reduces spent wash quantity. Thus, spent wash generation will be minimum. The treated wastewater will be utilized for plant floor washing, make up water for cooling tower, green belt in the area and captive irrigation. Thus, impact on ground & surface water shall be negligible and zero wastewater discharge scheme involves conversion of spent wash after evaporation to bio-compost using press mud.

(c) Seven Effect Falling Film Evaporation Unit
The suggested treatment scheme is a SEVEN EFFECT Evaporation Plant for Bio- Methanated Spent Wash Evaporation. The following points will elucidate the basic working principle:
Shell & Tube type Evaporators with highly efficient liquid distributor working on the principle of Falling Film Evaporation have been used, with Shell & Tube type Preheaters for preheating of FEED stream which serves the purpose of energy conservation.
Steam is fed to the first effect evaporator shell side at the given pressure and temperature as the heating medium.
Athani Sugars Ltd.
EIA/EMP for Expansion of Sugar, Distillery & Cogen Plant in Dist. Belgaun, Karnataka 4-22
The Feed from the Feed balance tank is taken to the High Heater for removal of non-condensible gases and passing to PHE-1 to make the best heat recovery.
The Feed after getting heated to the predetermined temperature in preheater is fed from the of the second effect evaporator which is Falling Film Evaporator -1
Then the feed from High heater is given to first effect evaporator and follows the flow path given below.
Inlet Feed -HH- HE Flash Vessel- E1 - E2 - E3 Outlet
Vapors generated in 1st effect VLS (Vapor Liquid Separator) are used as heat source in the 2nd effect.
Vapors generated in the 2nd effect VLS are subsequently used as heat source for 3rd effect.
Finally Vapors from 3rd effect are condensed on shell side of Surface Condenser for Evaporator.
The product at the desired concentration of 24 - 25 % w/w TS is obtained at the outlet of the third effect, which is a Falling Film evaporator.
A Shell & tube type Multi-pass Surface condenser is employed for condensing the shell side vapors.
The Pure and the process condensate are collected in receiving vessels. Highly efficient operating pumps have been provided for pumping the required fluid.
The operation of the plant is under vacuum. Vacuum is created with the help of a water ring vacuum pump.
The plant is having high level of automation to get consistent output at required concentration.
The system operates under vacuum. Water-ring vacuum pumps are used to maintain a desired vacuum.
Cooling water from cooling tower is used in the surface condensers for condensing the vapors.

Total Land area Provided = 10.00 acres
Leakages will be collected from molasses tank will be collected in small pits. Cooling tower used is having closed system hence only make up water is required. 4.7.4 Rain water harvesting
There are number of ways recharging the ground water such as-
Recharging of bore wells
Recharge pits
Recharge trenches
Roof top rain water harvesting
Roof top rain water harvesting has been considered for the present case for recharge into pits. The typical rainwater harvesting structure layout at the building is proposed as given in Fig 4.6. It should be noted that process of recharging is a continuous and slow process. The results can be observed after a period of 3 to 4 years. The rain water likely to be recharge is calculated below:
Athani Sugars Ltd.
EIA/EMP for Expansion of Sugar, Distillery & Cogen Plant in Dist. Belgaun, Karnataka 4-26
Annual Rainfall in the area is = 0.5 m/year
Available roof top area for rainwater harvesting = 1279.24 m2
Roof Run off coefficient = 0.8
S = R x A x Cr = 0.5 x 1279.24 x 0.8 = 511.69 m3 / season Where, S = Mean rainwater supply in m3
R = Annual rainfall in mm/year A = Surface area of catchment in m2
Cr = Run-off coefficient
FIG 4.6: TYPICAL RAIN WATER HARVESTING STRUCTURE AT BUILDINGS In addition to the above, surface run off water harvesting from plant premises will be done into surface water reservoir. The surface water harvesting into surface reservoir will decrease water requirement during rainy days. Prior to entering into the surface water reservoir, a silt trap shall be provided in the storm water drain. Surface run off from roads, green and open area shall be led to the surface water reservoir. The water shall be passing through settling chambers before reaching the reservoir to reduce suspended particulate load. The mechanism of settlement of contaminants from rain water prior to reaching the surface reservoir is shown in Fig 4.7.

FIG 4.7: RAIN WATER OIL TRAP AND DESILTING CHAMBER PRIOR TO SURFACE RESERVOIR
4.7.5 Water conservation measures
Methods to be adopted for water conservation are:
Recycle of process water including vapor condensate and reuse of treated water
Evaporator condensate available from Sugar Plant will be reused in sugar plant and co gen plant
From Evaporate condensate from Distillery Unit will be reused in distillery unit itself
Effluent generated by cogen plant will be treated in existing sugar Plant having Preliminary and Secondary treatment. In the secondary treatment stage wise activated sludge treatment process will be carried out. Each stage consist of the aeration tank with fixed aerators and secondary clarifiers. The clear effluent from clarifier will be collected in polishing pond and water will be used for irrigation.
Rain water harvesting
4.8 LAND ENVIRONMENT - IMPACT & MITIGATION
During construction, some excavation, land filling and development aspects may be needed for leveling of the ground. During site clearance there may also be some accumulation of boulders at site. However, this disturbance be done only on temporary basis. At the end of the construction, the soil will be stabilized at the unpaved areas with the help of plantation activities. More than 33% of the 120.5 acres land owned by ASL has been envisaged to be covered with plantation including green belt. Since the plant species will be capable of checking soil erosion, the soil will be fully stabilised without any adverse change in erosion potential of the area.
Athani Sugars Ltd.
EIA/EMP for Expansion of Sugar, Distillery & Cogen Plant in Dist. Belgaun, Karnataka 4-28
The existing integrated sugar plant is already in operation and is spread over an area of 24 acres. No additional area is proposed. The company owns a total of 120.4 acres where plantation, composting, etc is carried out. So, there is no change in the land use of the core area since the expansion units will come up in the existing plant area of 24 acres. The resultant land uses within the plot is shown in Table 4.7.

The plant layout with proposed units, colony, greenbelt, utilities, etc. is shown in Fig 2.1. Photographs of the plant site are shown in Fig 2.2.
During operation phase, the landuse pattern will remain same as constructed/ used. The quality can land & soil degradation can be a matter of concern due to waste water & solid waste disposal on land. The same shall be addressed as follows:
There shall be waste water from the power plant will be neutralised and used for sprinkling and horticulture. The quality of the water shall be monitored to ensure that it is within norms for disposal land.
The solid waste generation for disposal will be negligible and will be stored in designated areas with impervious bases, thus, the impact on land shall be minimal.
The majority of the solid waste i.e. fly shall be used composting since it is rich in potash.
4.9 SOLID WASTE - IMPACT AND MANAGEMENT
A. Construction Phase
During Construction phase, there will be development of a shanty town with temporary establishment of residential and commercial nature. Therefore, there will be generation of solid waste. For, say, 500 persons involved in construction, it is assumed that both parents of a family would work while on an average two children would be non-working. Therefore, for 2000 persons residing/ visiting the site, at an
Athani Sugars Ltd.
EIA/EMP for Expansion of Sugar, Distillery & Cogen Plant in Dist. Belgaun, Karnataka 4-29
average rate of 100 gm/capita/day, atleast 0.2 TPD of solid waste will get generated. These will have to be segregated. The organic matter can be composted and non-biodegradables can be incincerated in the boiler. The recyclable will be sold to recycling vendors although components like paper & plastic serve as high calorific wastes for incineration in boiler.
B. Operation Phase
The various types of solid waste along with their impact and management is summarised in Table 4.8.
TABLE 4.8 SOLID WASTE - IMPACT AND MANAGEMENT

Hence, it can be see that in this plant as all solid wastes generated will be recycled in the process or composted and given/ sold to farmers due to high nutrient content. No net-solid wastes generated will be available for disposal. Fly ash, press mud and yeast sludge management are described below:
i. Ash handling and storage : Fly ash collected from the ESP hoppers and the air-heater hoppers and the ash collected from the furnace bottom hoppers can be used as landfill, during the seasonal operation of the plant, when bagasse will be the main and only fuel for the operation. The ash content in bagasse is less than two percent. In cane trash and the other biomass fuels proposed to be used the ash percentage will not exceed 10%. The total fly ash collected during off season could be used as a landfill. The high potash content in the bagasse ash makes the ash, a good manure. As the filter press mud from the sugar plant also has a good land nutrient value, it is possible to mix the ash and the press mud and sell the same to the farmers to be used in the cane fields. The maximum ash generated using bagasse, biomass and cane trash as fuels will be about 8640 M TPA.
This ash generated will be given freely to entrepreneur to convert to Bio compost as well as it will be used with press mud to convert to compost in own distillery.

ii. Pressmud Storage Yard : The pressmud storage yard of 75 m x 50 m will be made impervious by constructing it with 300 mm thick stone soling. 200 mm thick base garland canal to collect any leachate are rainy days water. The same water will be collected in a collection tank of 10 m x 10 m x 5 m and the same will be recycled.
iii) Yeast sludge management : ASL will adopt the state of the art continuous fermentation process with Multipressure Vacumn Distillation such that the generation of solid waste such as, yeast sludge is very less as compared to conventional batch process. The volume of sludge is only 0.5 1% of the total quantity of fermented wash. For 90 KLPD Rectified Spirit Plant the maximum quantity of sludge produced is 2,500 5,000Lt./day (wet basis). The sludge is dried and will be used for composting. iv) Details of waste generated other than Fly ash Boiler ash generated in co- generation used in biocompositing and some quantity sold to brick manufacture. Yeast sludge and ETP Generation sludge also mixed with press mud for bio composting.

4.10 ECOLOGY
4.10.1 Impacts
A. During Construction
During construction phase, there will be less negative impacts on terrestrial eco-system comprising birds and animals as the area proposed for construction has less trees. Despite attempts to minimise the cutting / felling to the extent possible, if trees will have to be felled, due permission will be taken from the Forest Department and compensatory tree plantation undertaken within the plant premises. With progressive growth of greenery, terrestrial eco-system will improve in course of time. Presence of water and food wastes during day time will attract some birds and small animals (squirrels, mongoose, etc) towards the site.
B. During Operation During operation phase, the impact zone is part of landscape involving rural areas. Impacts on biological environment in the buffer zone will be low during the operational phase as the overall emissions shall remain well within the permissible limits.
The general adverse impacts, usually in case of such an industry are:
Dust emission from plant and due to transportation, which affects the effective photosynthesis by covering the plant/tree leaves by thin dust layer during dry months which however will be washed away in rainy months.
Roadkill due to traffic
Athani Sugars Ltd.
EIA/EMP for Expansion of Sugar, Distillery & Cogen Plant in Dist. Belgaun, Karnataka 4-31
Disturbance to birds and animals due to bright light and unusual noise during operation activity.
Contamination of water bodies on which animals and birds are dependent or contamination of ground water due to effluents and sewage. However, in this case, the waste water from domestic and and industrial sources will be treated in septic tanks and ETP, respectively, and will be used for irrigation of plantation areas. Thus, there will not be any discharge of effluent from the plant. So, no impact is envisaged on the surface water bodies and on the fresh water eco-system or ground water quality.
C. Impact on cropping pattern
Belgaum District as such was described as cultivated area from the view of agriculture. At the beginning the crops like, Jawar, Wheat, Bajara, Groundnut, Chilli, were grown. Due to availability of river water the sugarcane growers increased to a large extent. The survey conducted in the project area indicated that there is no competing crop for sugarcane. High value crops like chillies, fruits and vegetables are grown in few villages. However, area under these crops is very meager. Jawar, wheat, bajra, safflower, sunflower and groundnut are other important crops that provide a source of income. Farmers reported that they are not happy with private traders about the payment received and the price offered to them for these products. Moreover, there is an certainty of the payment from traders and is generally delayed. In case of sugarcane, the first installment is assured within the first 15 days from the date of sugar cane supplied to the sugar factory. Farmers also feel that soyabean, jawar, groundnut, sunflower and wheat fetch less income as compared to sugarcane. Soyabean and groundnut crops are also affected due to rains during September and late August. Moreover, in spite of adopting recommended package of practices, the entire crop is lost most of the time leading to loss of income. The agro- climatic conditions and soil type prevailing in the operational area of ASL are very much congenial for healthy growth of good quality sugarcane. sufficient irrigation facility is also available from irrigation Schemes as well as Tube wells existing in the area. Water level of existing wells are reportedly increased because of regular monsoon during past few years and, hence, there is considerable scope to improve the cultivation practices and shift over to sugarcane. It is also observed that cultivators in command area are progressive and are aware of sugarcane cultivation practices. In view of above, local farmers other crops wish to switch over to sugarcane cultivation.
4.10.2 Mitigation measures
Although the impacts are very limited or negligible, it is proposed to improve the general ecology within the plant premises. Therefore, the following measures are proposed:
i. Plantation programme
To reduce the impact of air pollution, particularly the PM content, the creation and maintenance of a green belt and plantations within and around the plant is being and will be undertaken.
Athani Sugars Ltd.
EIA/EMP for Expansion of Sugar, Distillery & Cogen Plant in Dist. Belgaun, Karnataka 4-32
Company has planted several trees around factory premises No. Scientific name of tree Common Name No. of trees 1 Azadirachta indica Neem 100
2 Tamarindus indica. Linn Gulmohor 70
3 Manilkara zapota Chikko 50
4 Pongamia pinnata Karanj 100
5 Magnifera indica Mango 500
6 Saraca asoca Ashoka 100
7 Tamarindus indica. Linn Chinch 160
8 Cocos nucifera coconut tree 350
Total 1430
In addition to the trees, a variety of small flowering shrubs and plants will be planted in the gardens and lawns. These flowering plants will improve the aesthetics of the area. The selection of trees for plantation will be done judiciously keeping in mind the adaptability of trees to the climate of the region. Consultation with the forest officers and experts in the field will be done to identify the exact species to be planted. Thus, a positive impact will be there due to plantation within the plant premises. The green belt is proposed to constitute of fast growing native species.
33% of the total 120.0 acres land under the ownership of ASL is proposed for plantation.
ii. Wildlife protection measures
There is no Schedule-I species in the study area. As regards fauna is concerned, Squirrel, Mangoose, Indian Hare etc. are the mammals besides various species of ambhipians, aves and reptiles. The plant in the centre does not intend to interfere with the fauna. However, precautionary measures can be taken as mentioned below:
1. Construction of boundary or fence along the plant perimeter to prevent wild animals from straying into the plant area and getting harmed.
2. Establishment of greenbelt along the facilities periphery to act as a natural buffer between the surrounding area and the facilities. The greenbelt establishment around facilities and along roads will result in small sized fauna such as squirrels, hare, etc., reptiles and birds in finding a favorable habitat.
3. The roads leading to and from the plant shall be having caution boards warning drivers to slow down for animal crossings, if any develop in the future
4. The drivers shall be sensitized not to hit stray animals on the road. 5. The emissions from the plant shall always be kept within the norms so the
surrounding environment is always clean and comfortable for human and wildlife vegetation.
6. Care shall be taken that no food or degradable waste is openly disposed. This could attract wild animals near to human habitation and create man-animal conflict. Hence, disposal of wastes shall always be on the designated and protected place.
Athani Sugars Ltd.
EIA/EMP for Expansion of Sugar, Distillery & Cogen Plant in Dist. Belgaun, Karnataka 4-33
7. The company shall interact with the Divisional Forest Officer and find out whether any schemes are ongoing for the protection of the wildlife. If such schemes are ongoing, then monetary or logistic support shall be extended by the company. For example, the company can supply water to watering holes in the forests in study area during dry season Plantation in the forest blanks to increase the fodder availability in the forest.
8. While carrying out social welfare activities, awareness about the variety of faunal species, their status of protection and awareness of their behavior will be spread through posters/ seminars or discussions to sensitize the villagers. By gaining correct scientific information, the villagers will be in a better position to protect themselves from animals and in return not harm them. Such situation reduces man-animal conflict, which usually arise due to myths and fear or hatred of animals.
9. Plantation in the villages is also a part of the social welfare proposal, which may be done in a manner that it acts as a natural buffer between the villages and surrounding areas. Also, the choice of the species to be planted can not only be natural but also economic yielding trees such as those for firewood, fruits, gum, leaves, seeds or timber. Such schemes would be called social-forestry schemes and create a community resource due to which villagers need not go further to the jungles to get firewood, fruit, etc. When their visits to the forests reduce, the pressure on the forests reduces and makes it not only safer for the flora but also fauna. The impacts therefore can be mitigated with appropriate control measures
10. Water sprinklers and fire hydrants of adequate specification will be provisioned at strategic locations to deal with any emergency.
11. The treated effluent released from the plant will be utilized for raising plantation and maintenance of garden.
12. It will be ensured and monitored that noise level is not exceeded beyond 60 dBA. Noise level beyond work place will be reduced by planting green belt around the plant.
13. Air pollution will be kept minimum at work place and negligible beyond the plant premises by providing green belt in plant area, sprinkling water, etc.
14. Company has earmarked separate budget for environmental protection. 15. Plantation of fodder grass can b
nearby forests, as per directions of the Forest Department so that the animals stay back in the forests and do not enter the villages in search of food.
16. Awareness programmes will be conducted with the help of different voluntary organizations involved in conservation through various means like film, video shows, street plays, story telling etc.
iii. Command Area Development
The availability of bagasse is entirely placed on the quantity of sugarcane present in the ASL area. Although the project is based on the bagasse which is sourced from sugar unit. It may be foreseen that due to marginal rainfall quantity of bagasse shall be reduced. As a consequence power plant may have acute shortage of fuel. having
Athani Sugars Ltd.
EIA/EMP for Expansion of Sugar, Distillery & Cogen Plant in Dist. Belgaun, Karnataka 4-34
plan to plant fuel wood or other biomass plantation in the area of the factory can cover this. This can be a stopgap arrangement for the fuel for boilers to produce power for around 300 days in the year.
Based on the farmers survey carried out in the command area, it is recommended to undertake following activities in order to ensure uninterrupted sugarcane supply during the crushing season:
Development of Seed Nursery : It is recommended to develop seed nursery for sugar cane and fuel wood or other biomass varieties for distribution of the same to the farmers in the command area Seed Distribution : ASL will have to raise quality seed material and meet the demand so that old seed is replaced after every five years. Sufficient seeds of new high yielding varieties should also be multiplied in the seed farm. These varieties should be systematically distributed to help the farmers to plan their cropping pattern and cultivation of early / mid late / late varietiesWater Management : ASL will have to take due care to water management especially in the heavy soil region. Care should also be taken for proper drainage system. The region has natural slope and the higher region is free from water logging.
The inputs like pesticide, insecticide, fungicide, micro nutrient fertilizers, seeds of green manure, organic compost are easily available. There is no difficulty in procuring crop loans and M T Loans from PACs.
For implementing the above mentioned programs in the command area, training programs, Kisan-mela etc. could be conducted in various parts of the operational area. Thus, the gap between potential yield actual yield could be reduced.
It is to be noted that due to the developmental activities already introduced by ASL, sugarcane cultivation has improved. Many new cane varieties have been introduced and hence it can be concluded that systematic as well as sustained efforts would help to increase the yields of sugarcane.
Ultimately, farmers would undertake sugarcane cultivation and the responsibility of the promotional activity of cane cultivation has to be played effectively by the proposed ASL. Farmers are anxious about ASL expanding the sugar factory at the proposed site. Non-member of ASL should be attended to properly and even better than the present SSKs. Farmers are of the view that the area of sugarcane has been increasing steadily for the last few years as some irrigation projects have come up in the command area. However, following expectations from the proposed ASL shall be taken care of:
1. Cane price should be paid as per FRP calculations.
2. Good quality seed material of sugarcane should be provided by ASL, as there is no source for good seed material in the command area.
3. At the time of plantation, crop loan and basal dose of fertilizer should be linked so that farmers apply the basal dose of fertilizer
Athani Sugars Ltd.
EIA/EMP for Expansion of Sugar, Distillery & Cogen Plant in Dist. Belgaun, Karnataka 4-35
4. ASL should make arrangement for soil testing and accordingly fertilizer doses should be recommended. It should be done not only for members of SSK but also for all farmers who supply sugarcane to ASL
5. ASL should provide the seeds of green manure. It is reported by a number of farmers that organic fertilizer coupled with chemical fertilizers if applied in balanced quantity, give a considerably higher yield of sugarcane particularly in medium and light soils. Thus, it is necessary that organic fertilizer be utilized to increase the sugar yield.
6. Presently sugarcane growers face great difficulty due to lack of road facility from the main road to farm. These roads are small in breadth and during rainy seas, these roads become unsuitable for transportation of sugarcane vehicles every year. Thus, there is concerted demand from the farmers that small roads should be developed into pacca roads.
7. Due to benefits accrued from the irrigation project, the number of electric pumps operating in the area as well as new pump connections would increase and there would be a long waiting list for electricity shortage and low voltage problems. SSSKL would ensure constant and continuous electricity supply for agricultural operations.
8. Farmers should be imparted training in sugarcane cultivation.
9. All studies, which are made available by the existing SSKs to their own members, should be provided to other sugarcane growers also.
10. Press mud and bio- field.
11. Interest rates on NRD and RD should be uniform in case of non-members as well as members.
12. In some of the villages, new lift irrigations schemes should be promoted.
13. Timely payment should be made to farmers.
4.11 SOCIO-ECONOMIC ENVIRONMENT
Like other sugar factories ASL is located in an isolated area. ASL management thought that it would be advantageous to improve the living conditions of people in and around the plant site. It also proposes to employ local skilled and unskilled workers for expansion stage also. It will therefore generate additional employment in the local area. ASL is also planning to setup additional 30 MW cogeneration plant for power production. It will resolve power crisis and will enhance earnings for village people. In turn local people can avoid uncertainty of job, raise their living standard, do supplementary jobs of cane & other farming, cattle, poultry, brick making unit etc. thus to stabilize & prosper in life. This will surely be a positive impact.
The existing production of sugarcane is much more than the requirement of these sugar factories. The balance sugarcane is presently sold to different sugar units in Belgaum district. In view of more availability of sugarcane than the demand of existing sugar factories, there is no certainty of getting a good price for the can and the sale price keeps varying. Moreover farmers are also not very happy about its
Athani Sugars Ltd.
EIA/EMP for Expansion of Sugar, Distillery & Cogen Plant in Dist. Belgaun, Karnataka 4-36
timely harvesting, as they have to wait till their round of harvesting comes because of which they loose time and cannot take up another crop. With the setting up of ASL, the demand of sugarcane will increase in the local area because of which there would be timely harvesting of sugarcane and the farmers are also likely to get a better price to the existing one thereby improving the economy of the local area projected in the proposals, ASL will be able to supply 12 MW surplus power generated in Phase I and 12 MW at the end of Phase II implementation to KV MSEB substation, from ASL site location. The production of power will resolve power crises and will enhance earning to village people. The consumption of bagasse for power generation will make ASL free from its disposal. The adjoining sugar factories marginal bagasse shall be diverted to ASL, which will reduce the load of its proper disposal. Encouraging the farmers in the ASL vicinity to plant more and more of fuel wood for cogeneration unit will substantially increase income level of the farmers.
The socio-economic benefits shall be as follows:
Ample power will be available from local grid due to decentralization of power generation
Power from grid on no charge basis or low charge basis can be available in this area.
This can be an initiative for many units to start.
Many sorts of direct as well as indirect job opportunities will be on the horizon due to expansion sugar, distillery and co-generation complex.
This will result in an increase in income level of the employees, subsequent commercial as well as social infrastructure establishment.
Supplementary type units can be initiated in the area like cattle preservation & protection, poultry, herbal medicinal plants, spices, pickles, papad and other food items, milk producer group co-operative small saving groups.
A detailed CSR plan has been prepared by the company to improve the socio-economic status of the surrounding people and is given in Chapter 9.
4.12 OCCUPATIONAL HEALTH AND SAFETY Occupational safety and health is very closely related to productivity and good employer employee relationship. The main factors of occupational health in proposed site are fugitive dust and noise. To avoid any adverse affects on the health of workers due to dust, heat, noise sufficient measures have been provided in the proposed project. These include:
Provision of rest shelters for workers with amenities like drinking water, fans, toilets, etc.
Provision of personal protection devices to the workers.
First-aid facilities on the site

jute, meat, fish, slaughter, paper, dry biomass etc. They affect whole body and can cause death. Remedy is to isolate, kill and avoid them to enter in body.
4.12.2 Guidelines on Specific Occupational Health Issues- prevention & protective measures
Persons working in bagasse based power generation plant are always exposed to solids, particularly fine dust of bagasse, trash and other fuel components. PM10 and PM2.5 enter air sacks after entering respiratory track where they settle. Due to precise size they are difficult to be removed from there. Moisture in fresh air and constant body temperature make them to build microbial colonies. Treatment in such cases to curtail the infection in respiratory track is a hail of a job for medical experts. Micro organisms have short life span and have to adopt consistently for the survival. Thus they develop capability to resist the drugs / therapeutic agents / antibiotics etc. It is a battle at global level for decades together. No correct curing agent / exact or permanent solution exist.
Persons working in bagasse based power generation area can get exposed to :
1. Excess air pressure zones and SPM prone area.
2. Higher temperature to follow heat exhaustion, cramps, stress, stroke
3. Moist / humid and dry weather area where skin damage may occur
4. Lifting of excess load can lead to damage to bones & spinal cord
5.
6. To lessen SPM, sprinkled water can lead to moist air. Such condition can lead to growth of mosquito, insects, flies population to lead to Malaria & other epidemic diseases
7. Electric shocks in case of short circuit
Various extents of the damages to different body parts can be:
1. Permanent or temporary deafness 2. Slight or severe damage to bones & spinal cord, joints 3. Anemic condition due to less RBC, WBC & lacking of new blood formation 4. Affect initial correct vision due to poor light as well as due to small particles 5. Damage to skin due to humid climate & water sprinkling, dermatitis / soricis,
cracks to skin, dry skin 6. Damage to respiratory track to lead to businosis, pneumokosis, pneumonia 7. Heat exhaustion, fatigue, stroke, rash, cramps, damage to muscles 8. Excess heat exposure may lead to damage to reproductive system 9. Electric shocks can lead to partial paralysis 10. Damage to eye due to incident light particles.
Athani Sugars Ltd.
EIA/EMP for Expansion of Sugar, Distillery & Cogen Plant in Dist. Belgaun, Karnataka 4-40
Thus probable routes to mitigate such damages can be:
1. Precise man power selection
2. Adequate pre employment training
3. Optimum supervision at all levels
4. Precise equipment selection
5. Periodic and exact lubrication of the equipment, machines.
6. Advance planning of substitution of equipment
7. Prevention of solids to enter in respiratory track.
8. As far as possible closed condition operation.
9. Use of natural and forced fresh air supply at work place
10. Adequate natural and forced air circulation as per needs
11. Proper bonding and earthing of the machinery
12. Proper insulation & core cover for power supply cables
13. Proper selection for material movement
14. Provision for cages, trolleys, carts, fork lifts, cranes, shuttles for movement of material and men
15. Automation of material handling
16. Sprinkling of enough water to mitigate SPM
17. Sufficient enlightening in work area when persons are inside
18. Provision to keep shop floor dry
19. Provision of enough drinking water when needed.
20. Provision of rest rooms / shelters to working staff
21. Prevention of fly, mosquito, insects in spread water to mitigate SPM
22. Provision of primary health center / first aid booths with adequate drugs, lotions, eye washers etc. and attendants.
23. Strict control to follow use of personal protective equipment like goggles, ear plugs, air muffs, aprons, helmets, rain coats, respiratory kits / air pipes, safety belts etc.
24. Periodic replacement of new / fresh teams to complete time scheduled task
Athani Sugars Ltd.
EIA/EMP for Expansion of Sugar, Distillery & Cogen Plant in Dist. Belgaun, Karnataka 4-41
Noise and Vibration
Relevant noise emitters at ASL are noise-making equipments such as Cutters, Crushers, Mixers, Compressors, Pumps, Centrifuges, Heat exchangers, Vacuum Filters, Boilers, and Turbines, D.G. Sets etc. All the equipments produce continuous noise. As deliberated in Chapter IV, noise level impacts of ASL operations are significant only on the operators of machinery and are negligible within buffer zone. This is because the noise produced by these machinery gets dissipated due to wave divergence, atmospheric absorption and absorption by noise barriers before being even felt in the buffer zone.
The continuous hammering of noise on the ears of the staff working in the factory premises may lead to some health problem, it can be circumvented by having small cabins with polycarbonate sheet or glass partition where in officers can carry out day-to-day work peacefully.
Following measures are proposed for controlling noise level impacts on machinery operators and within core and buffer zone of ASL.
Proper lubrication and regular maintenance of all the machinery used. Development of greenery / barriers / landscaping of trees/ bushes and shrubs. Reduced noise exposure to the operators of machinery by work scheduling
and by providing ear protective equipment. Use rubber packing in the foundations of machineries to prevent noise
transmission to the surrounding.
4.12.3 Safety hazards along with prevention & protective measures

affected persons and if the number increases with time attention would be required to improve the working environment.
Spirometry Test: Spirometry (meaning the measuring of breath) is the most common of the Pulmonary Function Tests (PFTs), measuring lung function, specifically the measurement of the amount (volume) and/or speed (flow) of air that can be inhaled and exhaled. Pulmonary function tests are done to diagnose certain types of lung disease (especially asthma, bronchitis, and emphysema), find the cause of shortness of breath, measure whether exposure to contaminants at work affects lung function, assess the effect of medication, measure progress in disease treatment etc.
Electrocardiogram (ECG) Test: The ECG is a diagnostic tool that measures and records the electrical activity of the heart in exquisite detail. The annual analysis helps in keeping track of heart related illness caused due to several occupational reasons.
Audiometry Test: Audiometry is the testing of hearing ability, involving thresh-holds and differing frequencies. Results of audiometric tests are used to diagnose hearing loss or diseases of the ear, and often make use of an Audiogram.
Vision Test: Eye examinations may detect potentially treatable blinding eye diseases, ocular manifestations of systemic disease, or signs of tumours or other anomalies of the brain.
4.13 EXPOSURE PATHWAYS
Exposure pathway is the path due to which exposure of the receptor takes place.
the process by which an organism acquires a dose. Table 4.9 identifies some of the major exposure pathways. There is are effluent and solid waste generated in the plant which is managed by using for irrigation and as manure, respectively.
TABLE 4.9 EXPOSURE PATHWAYS
Media Pathways Comment
Air- Gases and Aerosols
Respiration Assuming accurate fate model estimates, exposure is relatively predictable based on assumption of homogenous distribution in air. The air quality prediction model shows that this exposure pathway will be low impact for emissions from boiler.
Water- Soluble Chemicals
Respiration Assuming accurate fate model estimates, exposure is relatively predictable based on assumption of homogenous distribution in water. However, these will not be applicable in proposed plant due to absence of heavily contaminated effluents
Athani Sugars Ltd.
EIA/EMP for Expansion of Sugar, Distillery & Cogen Plant in Dist. Belgaun, Karnataka 4-46
Media Pathways Comment
Sediment (solids and pore water)
Benthic animals absorb chemicals, respire pore water or food or food from the water column. Plants rooted in the sediment may take up material from sediments, surface water and air
Processes are very complicated and usually simplifying assumptions are required. However, these will not be applicable in proposed plant due absence of heavily contaminated effluents
Soil (solids, pore water and pore air)
Organisms in soils may absorb material from soil, pore water, pore air, ingest soil, soil- associated food
Processes are very complicated and usually simplifying assumptions are required. The solid waste is all compostable and even the fly ash is rich in potash, thereby increasing the nutrient value of the soil on which this compost & flyash shall be used. The air emissions anticipated are also so low that they will have negligible impact
Ingested Food and Water
Consumption by fish and wildlife
Assume the test animal consumption rates in laboratory for a given availability of food or water are the same as those occuring naturally in the environment. In case of this plant, there will be no discharges to a surface water body, thus, fish and wildlife are not anticipated to get affected
Multimedia More than one of the above pathways
It is often possible to assume one pathway is dominant. In some cases, it will be necessary to estimate the combined dosage. In this project, such a pathway will be through the use of composted solid waste and use of treated effluent for irrigation, both on soil.
Source : Adapted from Table 3-5, Technical EIA Guidance Manual (COP) by IL&FS Ecosmart Limited, Hyderabad
Emissions from sugar mill and cogeneration plant can cause damage to human health, aquatic and terrestrial ecology as well as material due to mainly the soil exposure routes For example, adverse effects of the plants on human health can derive from the direct impact of suspended particulate matter and combustion gases emission on the organism and/ or their direct impact via the food chain and changes in the environment. But this impact will not be as high in comparison to any contamination that might occur due to contaminated effluent or comtaminated solid waste applied on soil and thereafter, on uptake by plants, finding its way into the animal food chain. The duration of exposure is decisive. Injurious heavy metals (e.g. lead, mercury, cadmium, etc) can enter the food chain and thereafter, the human organism by way of drinking water and consuming vegetables and animal products. Thus, monitoring of both effluent as well as solid waste quality shall be done, even though both are well extablished as nutrient rich and beneficial to plant growth.

CHAPTER 5
ANALYSIS OF ALTERNATIVES
5.1 SITE ALTERNATIVES
M/s. Athani Sugars Ltd. (ASL) proposes to expand its integrated sugar, cogeneration power project & Distillery at Kempwad village, Taluka Athani Dist. Belgaum, Karnataka in existing units. The proposed project is an expansion of sugar crushing capacity from 4500 to 12000 TCD, distillery from 60 to 90 KLPD and set up 24 to 54 MW biomass power plant for making RS/ENA/Ethanol. The expansion plant is being set up in the existing 120.5 acres of land.
The site had been selected because of the following reasons:
Availability of uninhabited, non-forest land at reasonable cost; Proximity to water source; Proximity to raw material source and cost-effective transportation logistics; Availability of infrastructural facility including road connection;
No alternative site was considered for the proposed expansion phase as the plant exist at the present site. There are no eco-sensitive locations such as bio-sphere, mangrove, protected forest, National parks etc. or environmental sensitive locations such as protected monuments, historical places within 10 km from the site.
5.2 TECHNOLOGY ALTERNATIVES
The process selection is done based on the following considerations:
i. Least stress on resources including raw materials and utilities ii. Reduce, Recycle and Reuse of wastes iii. Least or no pollution from the industry iv. Least or no risk to human and property v. Least or no adverse impacts on environment
The technology options for the proposed plant were considered based on efficient utilization of raw materials, fuel and water along with efficiency in power generation.
5.2.1 Cogeneration process
Cogeneration is a process that simultaneously produces two or more forms of useful energy, such as electric power and steam. It harnesses the thermal and electrical energy that is released as part of the production process in various industries. When a fuel is burnt to generate heat, and that heat is exploited in a thermo dynamic cycle to produce electricity, a great deal of energy is wasted. This wasted energy (which can be up to two-thirds of the energy content of the fuel) emerges as heat. If that heat can be utilized for space heating, for making hot water or in a manufacturing process, it could reduce the amount of additional energy needed for those purposes. This makes the economics of cogeneration extremely favorable.

EIA/EMP for Expansion of Sugar, Distillery & Cogen Plant in Dist. Belgaun, Karnataka 5-2
Benefits of Cogeneration
Cogeneration offers higher efficiency and lower waste on the one hand, and greater fuel flexibility and lower costs on the other. However, with the benefit of new technology a much wider range of industries, from sugar to chemicals to textiles, is employing cogeneration. Its potential is just beginning to be realized.
Cogeneration utilize the available energy in more than one form, they use significantly less fuel input. The cogeneration reduces energy costs and offers fuel flexibility. It also protects a company from the effects of power cuts and improves the quality of power. And finally, it reduces wastes.
Technologies of Cogeneration
Cogeneration can be implemented in many ways. Small diesel engines, gas turbine plants with waste heat boilers, combined cycle cogeneration stations, biomass-based plants can be used to provide heat as well as generate electricity. There are two types of cogeneration plants.
Topping cycle: Primary fuel is used to produce electricity, and thermal energy which is the by-product is then used for process heating.
Bottoming cycle: Primary fuel is used to produce heat which is required for the process at high temperatures and hence, power is generated through a suitable waste heat recovery system.
5.2.2 Distillery
Fermentation process is Hi-Ferm GR. continuous fermentation with two-fermenter system various input raw molasses, process water, nutrient solution and concentrated sulphuric acid are feed to the fermenter in a fixed proportion.
Carbon dioxide gas generated during reaction is scrubbed in a carbon dioxide scrubber is fitting with sieve trays and scrubbing is done with process water. Using anti-foaming agent TRO controls foaming during fermentation. Anti foam is continuously circulated with the help of pumps. The temperature of fermentation wash is maintained by plate type heat exchanger by cooling water.
The fermented wash overflows line given to fermenter No. 1 to fermenter No. 2. 30 % spent wash recycle to fermentation process and remaining spent wash is send to composting. In this process yeast activation tank is plays an important role. This is used for an aerobic condition for maximum growth of yeast side. Then continuously feed to fermenter No.1 for yeast activation tank Sp. Gr. is adjusted at 1.050.
In fermentation section 2 nos of fermenters are in series having capacity 340m3 each. Fresh biomass propagated in yeast propagation section is seeded in first fermenter. Then start 25 % (of flow chart) molasses and process water feeding to the fermenter the feedings of molasses and process water increases up to 100 % by observing & maintaining the fermenters parameters. After filling of the first fermenter, overflow of this fermenter is transferred to second fermenter. Here also given molasses and process water feeding as

per the flow charts. Yeast converts fermentable sugars to alcohol and carbon dioxide under optimum conditions. As alcohol fermentation is exothermic process, heat is released during the process. Dedicated forced re-circulation fermented wash coolers for each fermenter cools the wash to maintain optimum temperature in between 30 - 32 C, which is required for yeast activity. The fermented wash is then transferred to the yeast settling tank. Fermented wash from wash charger is feed to analyzer column with centrifugal pump.
Manufacturing process of wash to ENA on Multipressure Vacuum Distillation with DCS ccontrol system plant
After completion of fermentation process the next stage in the manufacture of wash to ENA is to separate alcohol from fermented wash and to concentrate it upto 96% alcohol by removing all traces of impurities like aldehydes, ketones & higher alcohols etc. is called as
following equipments.
Analyser Column
The main purpose of this column is to extract total alcohol from the fermented wash. The fermented wash first feeds to analyzer through spent wash PHE (Plate type heat exchanger) where fermented wash is heated by means of spent wash. Hot fermented wash from PHE goes to Analyzer column top tray. Analyzer column operates under vacuum. The top alcohol & water vapours of this column feeds to Pre-rectifier column bottom. Rest of the fermented wash flows down & it is drain as spent wash from Analyzer column bottom.
Pre-rectifier column
The top vapours of Analyser column having temperature 73 C are feed to bottom of pre- rectifier column. Pre-rectifier bottom liquid is heated by these vapours. The Pre-rectifier column operates under vacuum. The vacuum is created in second condenser through alcohol scrubber. During creation of vacuum some alcohol vapours are sucked in the Alcohol scrubber. In this scrubber, alcohol from the vapours are scrubbed by using soft water & scrubbed alcohol mix in the water is collected in to fusel oil washing tank. The top vapors of Pre-rectifier column are condensate & reflux through Ist, IInd & IIIrd condensers. The Technical Alcohol cut is drawn from same condensers. Low boiling impurities are concentrated in the Pre-rectifier column. The Alcohol water liquid from bottom of Pre-rectifier column is sent to stripper. Fusel oil build up is avoided in the Pre-rectifier column by withdrawing out side streams of Fusel oil as LFO & HFO. The Rectified spirit drawn from Pre-rectifier column is fed to Extractive Distillation column.
Stripper column
Stripper column is fitted with thermo-siphon reboiler. The steam applied to the stripper column through reboiler. Stripper column also operates under vacuum. The Alcohol water liquid from bottom of Pre-rectifier column is sent to stripper. The top vapours of this column feeds to Pre-rectifier column bottom. Stripper column bottom liquid drain as spent lees which is alcohol free.
Athani Sugars Limited
EIA/EMP for Expansion of Sugar, Distillery & Cogen Plant in Dist. Belgaun, Karnataka 5-4
Extractive Distillation Column (E.D.)
Alcohol drawn from Pre-rectifier column is feed to Extractive Distillation column (ED) middle plate. To remove low boiling point impurities from alcohol deminarilised water (D.M water) + spent lees (1:3) feed to ED column mixing bottle. ED column liquid is heated through steam by thermo-siphon reboiler. The top vapors of ED column goes to simmering column reboiler & bottom liquid of ED column is pre-heated in PHE by spent lees of rectifier column & goes to Rectifier column. E.D. column is operates at atmospheric pressure.
Rectifier cum Exhaust Column
Rectifier cum Exhaust column is operated under pressure (2.1 to 2.2 A). Top vapours of rectifier goes to analyzer reboiler shell side. Here, these vapours are exchange heat to analyzer spent wash. Then spent wash vapours are collected in flash tank. These vapours reheats analyser column bottom. The reboiler shell side condensate are collects in the rectifier reflux tank & refeed to the rectifier column top plate No.72 by pump. Alcohol is enriched on plate No. 68 & is drawn out as Rectified spirit (96%). This RS feeds to simmering column middle plate. This column liquid is heated through steam by thermo-siphon reboiler. Fusel oil build up is avoided in the Rectifier column by withdrawing out side streams of Fusel oil LFO & HFO. These LFO & HFO feeds to fusel oil concentration column.
Simmering Column
The simmering column is most important column in ENA production. This column helps to minimize the volatile acids contents from R.S. which is drawn from Rectifier column. This column is totally fabricated in de-oxidized copper. The principle behind that to react the impurities in the alcohol with copper & neutralize it. This column is operates at atmospheric pressure. This column liquid is heated by top vapors of ED column through reboiler which is situated at bottom of simmering column. The top vapors of this column are reflux through Ist & IInd condensers. The technical alcohol cut is drawn from same condensers. Condensed alcohol water liquid from reboiler fed to recovery column. The salient pure Extra Neutral alcohol (ENA) product is drawn from bottom of simmering column & sent to tester through ENA cooler. This column is operates at atmospheric pressure.
Fusel Oil Concentration Column / Recovery Column
Fusel Oil Concentration (FOC) column basically works for concentrating the fusel oil received from the rectifier column, Pre-rectifier column so as have effective separation of heavy fusel oils and recovering the alcohol from the FO decanter. Simmering column reboiler condensed liquid is also fed to this column. Steam is given to this column through reboiler. The top vapors of recovery column are refluxed through Ist & IInd condensers, Technical alcohol cut is drawn from same condensers. LFO & HFO drawn from same column & which cooled through double pipe heat exchanger & sent to decanter for further separation the fusel oil wash water is fed to stripping column. This column is operates at atmospheric pressure.

CHAPTER 7
ADDITIONAL STUDIES: DISASTER MANAGEMENT PLAN
SUMMARY OF PUBLIC CONSULTATION
Additional study on disaster management plan has been included out in this chapter along with summary of public consultation.
7.1 RISK ANALYSIS AND DISASTER MANAGEMENT PLAN
ASL will be a new growth oriented center in the Athani taluka. Such unit can pose threat of danger / hazard due to storage of hazardous materials. The power plant also poses electrocution, fire, and explosion hazards. When the full fledged activities of sugar, alcohol & co-generation will gear up, they will have to follow Factories Act 1948 with all amendments till today and any directives from Director Safety, Health & Environment [SHE] will automatically be binding on ASL. In such condition to appoint a qualified Safety Officer is a must & will be an adequate, wise step in such direction. On site and off site disaster control plans and their perfect implementation will be part and parcel of the management & such safety officer. To lessen the probability of hazard to occur & avoid the consequent damage, a disaster management and control plan has to be worked out for whole complex in anticipation to the threat.
7.2 RISK ASSESSMENT
The main objective of the risk assessment study is to propose a comprehensive but simple approach to carry out risk analysis and conducting feasibility studies for industries and planning and management of industrial prototype hazard analysis study in Indian context.
Risk analysis and risk assessment should provide details on Quantitative Risk Assessment (QRA) techniques used world-over to determine risk posed to people who work inside or live near hazardous facilities, and to aid in preparing effective emergency response plans by delineating a Disaster Management Plan (DMP) to handle onsite and offsite emergencies. Hence, QRA is an invaluable method for making informed risk-based process safety and environmental impact planning decisions, as well as being fundamental to any facility-siting decision-making. QRA whether, site-specific or risk-specific for any plant is complex and needs extensive study that involves process understanding, hazard identification, consequence modeling, probability data, vulnerability models/data, local weather and terrain conditions and local population data. QRA may be carried out to serve the following objectives.
1. Identification of safety areas
2. Identification of hazard sources
3. Generation of accidental release scenarios for escape of hazardous materials from the facility
4. Identification of vulnerable units with recourse to hazard indices
Athani Sugars Limited
EIA/EMP for Expansion of Sugar, Distillery & Cogen Plant in Dist. Belgaun, Karnataka 7-2
5. Estimation of damage distances for the accidental release scenarios with recourse to Maximum Credible Accident (MCA) analysis
6. Hazard and Operability studies (HAZOP) in order to identify potential failure cases of significant consequences
7. Estimation of probability of occurrences of hazardous event through fault tree analysis and computation of reliability of various control paths
8. Assessment of risk on the basis of above evaluation against the risk acceptability criteria relevant to the situation
9. Suggest risk mitigation measures based on engineering judgement, reliability and risk analysis approaches
10. Delineation / up-gradation of Disaster Management Plan (DMP).
11. Safety Reports: with external safety report/ occupational safety report
7.3 DISASTER MANAGEMENT PLAN
Disaster can occur as on site or off site variety i.e. disaster on campus or disaster in nearby area causing indirect damage to site area & the complex.
Disaster may occur due to two categories, natural and manmade calamities:
Natural calamities cover Flood, Storm / typhoon, Earthquake, Heavy mist, fog, hail storm, Land slide
Man made calamities involve Fire & Explosion, All types of leakages & spillage, Electrocution, excavation, construction, erection, Sabotage, rail & road accidents, mass agitation, Looting, Morcha, war
The identified hazardous areas in the complex are :
1. Boiler area - Explosion
2. Turbine section - Explosion
3. Electrical rooms - Fire and electrocution
4. Transformer area - Fire and electrocution
5. Cable - Fire and electrocution
6. Storage facilities Fire / spillage for alcohol
Considering various probabilities the management & safety department has to create safety awareness & preparedness in all employees and people in vicinity area in case of any sort of emergency to occur & a chalked out attempt to surely overcome the disaster in time. This includes preparation of onsite and offsite disaster control plans, their mock drills at least 2
Athani Sugars Limited
EIA/EMP for Expansion of Sugar, Distillery & Cogen Plant in Dist. Belgaun, Karnataka 7-3
times in a calendar year, reports for the same to DISH & due amendments for the perfect implementation.
7.3.1 Level of Accident
If there is any disaster in any part of plant/work place due to any reason the level of accidents from damage point of view may vary. Accordingly accident prevention program will have to be initiated by safety department simultaneously.
7.3.2 Critical Targets During Emergency
Level I Accidents
Under this level disaster may happen due to electrocution, fire explosion, alcohol spillage and spontaneous ignition of combustible material. This level has probability of occurrence affecting persons inside the plant. Various hazardous areas identified in the plant are potential areas to be affected due to level I accidents.
Level II Accidents
Disaster of this level can occur in case of sabotage and complete failure of all automatic control/warning systems, and also if the alcohol stored in tank and covered by tank bunds leaks out. However, probability of occurrence of this is very low due to the proposed adequate security training, and education level of plant personnel for the captive power plant.
7.3.3 Site Emergency Control Room (SECR) & Site Main Controller
In each segment of work, from domestic level to war fighting team level approach always helps. If the concerned man is aware of his duty at his place & need of the time, he can complement the huge task of lessening the damage of the disaster. To overcome the emergency in its occurrence, the strategy is to be prepared in advance, plan for the team effort, educate others and reduce all effects of disaster.
In case of any disaster main responsibility lies with the Chairman and Board of Directors, where they can nominate one fellow to be responsible person who will be Chief Incidence Controller (IC). In case of disaster key person like Chief engineer, Chief chemist, Distillery manager will be the site main incidence controller and will commence respective duties in that capacity to curtail the emergency & minimize the losses may be occurring.
People in all departments can assist in contacting external persons, district, state & central authorities, hospital & ambulance contact and evacuation, if needed, for people in the vicinity with assistance of state transport buses. People from maintenance department can help in rectifying the fault in system. Security persons assist in fire fighting & material movement operation to avoid losses. It is utmost necessary to prepare the control plan & to involve all staff in factory to get any sort of external help / assistance in time to lessen all sorts of damage.
To assist the disaster control more effectively a site emergency control room (SECR) will be established at the plant site. The SECR may be provided with following sections:

7.3.6 Alarm System to be followed During Disaster
ILIbroad cast disaster message through public address system. On receiving the message of
m system will be explained to one and all to avoid panic or misunderstanding during disaster.
It is necessary to take one trial for perfect functioning of the siren at least once in one week with prior intimation to Belgaum District Collector.
7.3.7 Storage of Flammable Liquids
The Dangerous Substances and Explosive Atmospheres create risks from the indoor storage of Dangerous Substances to be controlled by elimination or by reducing the quantities of such substances in the workplace to a minimum and providing mitigation to protect against foreseeable incidents.
These should be located in designated areas that are wherever possible away from the immediate processing area and do not jeopardise the means of escape from the workroom/working area. The flammable liquids should be stored separately from other dangerous substances that may enhance the risk of fire or compromise the integrity of the container.
The ethanol is flammable liquid and to handle properly as per the guidelines. This project is having storage of ethanol of about 90 KLPD. The storage involves 4 no of bulk storage available. The plant having capacity of 330 days storage capacity.
i. Handling: Wash thoroughly after handling. Use only in a well-ventilated area. Ground and bond containers when transferring material. Use spark-proof tools and explosion proof equipment. Avoid contact with eyes, skin, and clothing. Empty containers retain product residue, (liquid and/or vapor), and can be dangerous. Keep container tightly closed. Avoid

contact with heat, sparks and flame. Avoid ingestion and inhalation. Do not pressurize, cut, weld, braze, solder, drill, grind, or expose empty containers to heat, sparks or open flames.
ii. Storage: Keep away from heat, sparks, and flame. Keep away from sources of ignition. Store in a tightly closed container. Keep from contact with oxidizing materials. Store in a cool, dry, well-ventilated area away from incompatible substances. Flammables-area. Do not store near perchlorates, peroxides, chromic acid or nitric acid. 7.3.8 Emission Mechanisms And Control Considering Storage Tanks Emissions from organic liquids in storage occur because of evaporative loss of the liquid during its storage and as a result of changes in the liquid level. The emission sources vary with tank design, as does the relative contribution of each type of emission source. Emissions from fixed roof tanks are a result of evaporative losses during storage (known as breathing losses or standing storage losses) and evaporative losses during filling and emptying operations (known as working losses). External and internal floating roof tanks are emission sources because of evaporative losses that occur during standing storage and withdrawal of liquid from the tank. Standing storage losses are a result of evaporative losses through rim seals, deck fittings, and/or deck seams. The loss mechanisms for fixed roof and external and internal floating roof tanks are described in more detail in this section. Variable vapor space tanks are also emission sources because of evaporative losses that result during filling operations.
i. Fixed Roof Tanks: A typical vertical fixed roof tank is type of tank consists of a cylindrical steel shell with a permanently affixed roof, which may vary in design from cone- or domeshaped to flat. Losses from fixed roof tanks are caused by changes in temperature, pressure, and liquid level. Fixed roof tanks are either freely vented or equipped with a pressure/vacuum vent. The latter allows the tanks to operate at a slight internal pressure or vacuum to prevent the release of vapors during very small changes in temperature, pressure, or liquid level. Of current tank designs, the fixed roof tank is the least expensive to construct and is generally considered the minimum acceptable equipment for storing organic liquids.
ii. Floating Roof Tanks : There are two types of floating roof tanks External and Internal. A typical external floating roof tank (EFRT) consists of an open- topped cylindrical steel shell equipped with a roof that floats on the surface of the stored liquid. The floating roof consists of a deck, fittings, and rim seal system. Floating decks that are currently in use are constructed of welded steel plate and are of two general types: pontoon or double-deck. An internal floating roof tank (IFRT) has both a permanent fixed roof and a floating roof inside. There are two basic types of internal floating roof tanks: tanks in which the fixed roof is supported by vertical columns within the tank, and tanks with a self-supporting fixed roof and no internal support columns. Accidental Release Measures
General Information: Use proper personal protective equipment as mentioned below:
Eyes: Wear appropriate protective eyeglasses or chemical safety goggles as described by OSHA's eye and face protection regulations in 29 CFR 1910.133 or European Standard EN166.
Athani Sugars Limited
EIA/EMP for Expansion of Sugar, Distillery & Cogen Plant in Dist. Belgaun, Karnataka 7-8
Skin: Wear appropriate protective gloves to prevent skin exposure.
Clothing: Wear appropriate protective clothing to prevent skin exposure.
Respirators: A respiratory protection program that meets OSHA's 29 CFR 1910.134 and ANSI Z88.2 requirements or European Standard EN 149 must be followed whenever workplace conditions warrant a respirator's use.
Spills/Leaks: Absorb spill with inert material (e.g. vermiculite, sand or earth), then place in suitable container. Remove all sources of ignition. Use a spark-proof tool. Provide ventilation. A vapor suppressing foam may be used to reduce vapors.
Fire Fighting Measures :
General Information: Containers can build up pressure if exposed to heat and/or fire. As in any fire, wear a self-contained breathing apparatus in pressure-demand, MSHA/NIOSH (approved or equivalent), and full protective gear. Vapors may form an explosive mixture with air. Vapors can travel to a source of ignition and flash back. Will burn if involved in a fire. Flammable Liquid Can release vapors that form explosive mixtures at temperatures above the flashpoint. Use water spray to keep fire-exposed containers cool. Containers may explode in the heat of a fire.
Extinguishing Media: For small fires, use dry chemical, carbon dioxide, water spray or alcohol resistant foam. For large fires, use water spray, fog, or alcohol-resistant foam. Use water spray to cool fire-exposed containers. Water may be ineffective. Do NOT use straight streams of water.
Flash Point: 16.6 deg C ( 61.88 deg F) Autoignition Temperature: 363 deg C ( 685.40 deg F) Explosion Limits, Lower:3.3 vol % Upper: 19.0 vol %

EIA/EMP for Expansion of Sugar, Distillery & Cogen Plant in Dist. Belgaun, Karnataka 8-1
CHAPTER 8
PROJECT BENEFITS
All organisations have an impact on the society and the environment through their operations, products or services, and through their interactions with key stakeholder groups including employees, customers/clients, suppliers, investors and the local community. Generally speaking, it can be stated that Corporate Social Responsibility (CSR) was born as a response to a growing gap between two societies in terms of economic, social and environmental development.
ASL has identified 6 key principles of CSR, as follows:
Must take care of their employees and investors
Must satisfy market demands and gain new customers
Must improve their relationships with providers
Must listen to community expectations
Must be concerned about the environment
Must promote and facilitate intercultural dialogue
In order to incorporate each of those principles into their everyday activities, ASL shall include them in every project activity as well.
8.1 EMPLOYMENT POTENTIAL
Currently 500 employees are working and additional 300 will get employment during expansion. In addition to these, indirect workers will be several times and the farmers supplying sugarcane is surrounding areas will benefit. For employment, preference will be given to local population for employment in the semi-skilled and unskilled category. Hence, the company has also envisaged various skill-building programmes for locals. Therefore, the significant positive impact on employment and occupation is envisaged on account of better economic status of the community due to better earnings, higher inputs towards infrastructural facilities due to establishment of plant and enhancement of literacy due to educational facilities available in the surroundings.
8.1.1 Employee youth for training in skill
Employee youth for training in skill relevant to the project for eventual employment in the project itself shall be as under ASL will continuously have interactions with Schools, Junior Colleges, Industrial Training Schools located in Athani taluka. Training Division of ASL will have campus interview in the Schools, Junior College, Industrial training Schools located in Athani taluka.
Athani Sugars Limited
EIA/EMP for Expansion of Sugar, Distillery & Cogen Plant in Dist. Belgaun, Karnataka 8-2
After selecting the youth they will be provided ITI training in the following areas
1. Fitters 2. Welders 3. Carpenters 4. bar bending 5. Mason 6. Maintenance of Pumps and other mechanical equipments 7. Electrical Maintenance 8. Environment Monitoring 9. Green belt Development ( Gardner Training) 10. Laboratory Chemist (Water Testing) 11. Brick Manufacturing 12. Vehicle Driver
After successful training the youths will be appointed at appropriate position in ASL.
8.1.2 Capacity Building and Training for vocational Courses
ASL will provide the vocational training for youth as per their qualification and interest. This will enable them to get employment at proposed power plant. It will increase their social and economical status.
ASL will implement this by hiring the proper and renowned institute from near by area (possibly Nagpur) to arrange the trainings. ASL will form a supervisory committee to inspect all the activities and also take care of the requirement for the training program.
8.2 PHYSICAL & SOCIAL INFRASTRUCTURE
The amenities within the plant and residential units such as drinking water, sanitation, STP, solid waste management, first etc have been provided. The same are available for the employees to avail. In the surrounding villages, CSR activities have been undertaken in the past for social and physical infrastructure development.
ASL shall support villagers in Road, sanitation facilities, shopping centers, solar lighting, community development, construct school building, primary health centers etc. Due to the establishment of the proposed plant, there will be development of communication facilities in the area. The plant office and workers rest shelters will be equipped with sufficient infrastructural facilities including drinking water, toilets, sanitation facilities, health centre, etc. Education and medical facilities will be provided to the employees and to their family members and will also be extended to the villagers. Shopping complex and banks will come up in the locality, which will be beneficial for local villagers also.
Athani Sugars Limited
EIA/EMP for Expansion of Sugar, Distillery & Cogen Plant in Dist. Belgaun, Karnataka 8-3
Drinking water facility : ASL has proposed to make provision for drinking water at the said villages. ASL will meet this requirement by constructing water storage tank, bore wells and hand pumps.
8.3 CSR PROVISION BY ASL
In addition to the above, ASL is planning for the following:
ASL is planning for developing nearby villages as per the identified requirement of the region under CSR activity. This will increase the social and economical sector of the region. ASL has decided to adopt three near by villages to implement CSR. The identified villages are Kempwad, Madhbhavi, Khatav ,Siddhewadi. These villages were selected on the basis of shortfall of basic amenities. Majorly these villages are depending on the agriculture. Following are the identified provision for the area:
Capacity Building and Training for vocational Courses
Village infrastructure
Sustainable power development
Drinking water facility
Women Empowerment trough training and financial support
Education Support through Extension of Building, Scholarship, Books
Primary Health Centers through health camps, upgradation of Building, New Building etc
Agriculture Development Program
8.3.1 Women Empowerment trough training and financial support
ASL has proposed to develop the training center as handy craft making, household goods making, tailoring etc. It will increase the economic level of the region.
8.3.2 Education Support through Extension of Building, Scholarship, Books
ASL is planning to improve educational level of the region. It will be implemented by helping school building construction, providing books to poor student, scholarship to financially poor students per year as per their previous academic record. This will motivate the student in education. ASL will give opportunity to educated youth to work in plant.
8.3.3 Primary Health Centers through health camps, up-gradation of Building, New Building etc. ASL is willing to help in setup of primary health center, running free checkup camps, help in building hospitals and buying machineries, funding to health centers etc.

EIA/EMP for Expansion of Sugar, Distillery & Cogen Plant in Dist. Belgaun, Karnataka 8-4
8.3.4 Agriculture Development Program
Training on agriculture extension service e.g fertilizer application, paste management, agri clinic, and will regularly be conducted by reputed agriculture institutes.
8.3.5 Other benefits from the project
Near the Navanihal and other areas in Athani Taluka the irrigation schemes and sugarcane growing will be sufficient to fulfill the requirement of ASL.
This project will have long run benefits in Indi taluka of Bijapur district. Sugar mill is an agro based project using Sugar cane as sole raw material. Sugar cane cultivators i.e. Farmers will receive many benefits such as transport, education, community center etc.
In the first stroke due to less distance from the farms they will get good price for cane. Next, farmers will get compost from waste streams to be used as nutrients on farms. Thus, they will achieve good returns for cane.
At the same time utilizing conservation plan they will get precious nutrients at merely throw away price. In this area crops like cotton, tur, jawar, bajra are cultivated, which will also fetch profits to the farmers.
Waste of sugar mill i. e Bagasse and imported coal are useful for power generation and molasses is utilized for Ethanol production.
There will be remarkable reduction in the waste from the complex. Thus such an attempt of use of waste material will also provide ASL an opportunity to pay higher price to sugarcane grower.
ASL plans to produce anhydrous ethanol to provide precious fuel to automobiles and contribute to save Petrol, thereby foreign exchange. Indian Oil sector obtains fuel ethanol from sugar sector with good price.
Power shortage is a crucial issue in the Country. A decision to opt for co-generation by ASL using bagasse will provide power for self consumption and also other parts of villages under rural electrification plan.
This will raise funds to pay good price to farmers. This industry will provide revenue to State and Central Government.
At village Athani of Belgaum district, good scope exists to provide facilities like road, power, health care centers and educational institutes in the area. MSPSL has already initiated socioeconomic development of the nearby villages.
It will be a nucleus for forecasted accelerated growth in the region. As cash money will be available to the farmers cooperative supplementary units to farms like poultry, cattle growing and milk products and other food items, silkworm growing and silk weaving, Edible seeds crushing to yield oils, hand made paper units can be initiated. ASL decides profoundly to initiate this plan amongst the villagers and farmers jointly.
Athani Sugars Limited
EIA/EMP for Expansion of Sugar, Distillery & Cogen Plant in Dist. Belgaun, Karnataka 8-5
Both direct and indirect employment is next important issue at the door step. ASL has initiated recruitment of senior staff and persons needed in construction phase to minimize migration from village to city.
At the national and the state levels the benefits include decentralized power generation, reduction in T&D loss, reduced emissions, reduction in the imports of petroleum products, increased tax revenues and reduction in the transportation cost. The project will have excellent multiplier effect and will become truly a win-win situation for all the stakeholders and for local people.

Athani Sugars Ltd.
EIA/EMP for Expansion of Sugar, Distillery & Cogen Plant in Dist. Belgaun, Karnataka 11-2
On a theoretical basis 342 kg of sugar yields 184 kg of 100% alcohol and 176 kg of CO2.Usual commercial efficiency obtained are in the range of 85% fermentation and 98 to 99% distillation, contributing to a total efficiency of 83 to 84%.
Ethanol or ethyl alcohol, CH3-CH2-OH is a volatile, flammable, clear, colourless liquid which finds many applications as a raw material for acetone, acetaldehyde, acetic acid, acetic anhydride, ethyl acetate, other esters, and syntheses along with its main use due to associated oxygen from hydroxyl group in fuel blending in gasoline. Alcohol distillation will yield quality rectified alcohol. Spent wash will be used along with press mud for composting.
Bagasse from cane crushing and coal will be burnt in 130 T/H boiler for cogeneration of 24 MW power with turbo generator. Press mud from cane juice filtration will be used in composting and the same will be supplied to cane farmers. Ash from boiler will be sold to brick producers or used in land filling.
11.2.3 Raw material, power and water
500 TCH of sugarcane required for sugar plant will be from own farms and any shortfall to be met from the nearby farmers for the sugar plant whereas the molasses (76800 MT or 351.5 TPD) and bagasse (150 TPH) will be used from within the plant. The transportation shall be done through tractor trolleys, trucks and carts, as per the mode available with the farmer.
Company proposes to have power supply from 440 V, 50 cycles from in house captive power plant of sugar mill. Hence the power supply from the grid is not proposed as the power supply will be available from the cogen power plant. The estimated power requirement will be 130 kwh/KL for RS, 139 kwh/KL for ENA and 140 kwh/KL for Ethanol.It is inclusive of power consumption in plant, off-site equipment, factory lighting, etc. Backup generator of 1250 KVA is also provisioned for future.
Total fresh water requirement shall reduce to 1,89,472 KL/annum after expansion from the existing 2,45,360 KL/annum. The reduction will be 55888 KL/ annum i.e. by 22.78%. The water will be sourced from Krishna river for which the permission has been obtained.
11.2.4 Manpower
Total existing manpower the sugar factory is 500 and additional proposed manpower is 300 for expansion.

11.4 ENVIRONMENTAL IMPACT ASSESSMENT AND MITIGATION
11.4.1 Topography and drainage
Impact: The topography of the proposed site is plain with gentle slope and slightly undulation. The agriculture land was converted to industrial purpose at the first stage of installation of the plant.Thereafter an expansion was undertaken and currently a second expansion is proposed in this report in the same premises and area. Thus, no significant changes in topography in the core zone are anticipated since majority of the construction of the buildings such as walls, buildings, stock yards etc. have already occurred. The ground has already achieved a requisite level during previous construction phases. There will be no impact on topography of the buffer zone.
Mitigation: The additional change in topography in the core zone will not lead to additional changes in the sheet flow pattern of rain water within the core zone since most of the construction has been carried out in the previous phases of construction. Moreover, a network of planned storm water drainage is provided and maintained. The additional construction is expected to be completed in one year.
11.4.2 Air environment
Impact: During the construction phase, sources of air pollution will be vehicle exhausts, dust generation due to excavation work and exhaust from construction equipment like compressors, DG sets, etc.
Primary impact will be high dust generation resulting into increased SPM levels in the surrounding areas. The project has air pollution point source in the form of boiler stack. The air environment gets polluted due to emission of suspended particulate matter having particle size less than 50 microns and can have secondary impacts, if not managed.
The major pollutant from the activity is PM. In the present study, the major source has been considered as the stack attached to boiler. The maximum GLCs is calculated for existing scenario is 0.0086 3 NE Direction. Incremental rise due to proposed unit power plant will be 0.011 3 NE Direction. The cumulative impact due to existing and proposed operation will be 0.014 3 NE Direction.
Due to existing state highways & less distances for carts, tractors & trucks to reach mill site the suspended particulate matter generation is anticipated to be within specified limits.
Mitigation: During construction, welding operations shall be carried out within cordoned areas. During dry weather condition, the dust created by excavation, leveling and transportation activities will be easily controllable by sprinkling of water. Construction equipment and transport vehicle will be maintained properly to minimize source emissions and spillage. Regular maintenance schedule will be adopted.
During operation, Electrostatic precipitator (ESP) will be provided in the additional boiler stack. Use of bullock carts, which are environmental friendly, for transportation of sugarcane from the villages to the plant site as far as possible. Carry out tree plantation around plant area for minimizing environmental impacts of the proposed activities over a
Athani Sugars Ltd.
EIA/EMP for Expansion of Sugar, Distillery & Cogen Plant in Dist. Belgaun, Karnataka 11-7
period of time. Plantation program shall be designed and a budget should be allocated for this purpose every year. 33% of the area owned by ASL is planned for greening. Moreover, the garden development and tree plantation activities of ASL during operational face would ensure minimal impact of fugitive dust emissions. In addition to above, ASL promised to maintain good house-keeping in all the departments of their sugar manufacturing and power generation departments in order to keep the entire complex clean and free of dust.
11.4.3 Noise and traffic density
Impact: During construction phase, noise levels in the vicinity of any construction activity increase due to running of bull-dozers, excavators, transport vehicles, pile drivers, portable generators, mechanical machinery such as cranes, riveting machines, hammering etc. During operation phase, the noise levels near the sources such as Sugarcane cutting, Crushing, Lime addition, Clarification, Evaporation, Sugar separation, Steam Production, cutters, crushers, mixers, pumps, boilers etc. will be higher. The traffic involved for transportation by road will also cause noise pollution and affect habitation along the roads.
Mitigation: Provision and maintenance of green belt. Proper maintenance of noise generating machinery including transportation vehicles. The noise generation will be reduced at source by erecting noise dampening enclosures, by maintaining the machines and greasing them regularly. Provision of air silencers to modulate the noise generated by the machines/ equipments. The equipment will be provided with acoustic shields or enclosures to limit the sound level inside the plant. Use of rubber packing in the foundations of machineries to prevent noise transmission to the surrounding. Noise from safety valves, start up vents, steam jet ejectors of condenser etc. will be reduced by providing silencers at the outlet of down steam piping. Ear muffs/plugs provided to the workers in the close vicinity of noise source.
11.4.4 Water environment
Impact: During construction phase the requirement of water will be on account of concrete mixing, curing and tank preparation, usage in sprays and sprinklers for dust suppression, irrigation for plantation and for landscaping with decorative plants and lawns. During construction hardly 35 m3 water will be required for curing. The construction activity will not have any effect on ground as well as surface water. The plant will derive its water from the Krishna River, which is located at distance of about 13 km. The water requirement will be increased from 850 cum/day to 1298 cum/day after expansion for sugar plant. However, total water requirement on annual basis will be reducing by 22.78% from 245360 KL/A to 189472 KL/A. necessary pumping and piping system has been installed for water withdrawal from the proposed source. The lean season for Krishna river is in the month of May. However, sugar factory crushing season is closed in the April end. Total fresh water requirement for cogen and distillery plant will be 850 cum/day in season and 1367 cum/day in off season. Treated water will be used for the sugar plant. During the lean season Krishna river is never dried as it is perennial and the water flow in the river near drawl point always more than 5 cum. Hence there is no significant impact on drawl of water during April and May month i.e. lean season.
Mitigation: Waste water generated during construction is insignificant. Proper sanitation facility will be provided with septic tank so that there will be no negative impact on water.
Athani Sugars Ltd.
EIA/EMP for Expansion of Sugar, Distillery & Cogen Plant in Dist. Belgaun, Karnataka 11-8
Wastewater from Sugar mill will not have significant BOD/ COD levels. All waste water will be collected in effluent treatment chambers and neutralized prior to discharge in the existing sugar plants. The treatment scheme incorporates Aerobic treatment method for the wastewater with state of the art Bio-Aeration Technologies. In co-generation also precise design parameters will enhance target of water conservation & power production. Maximum attention is paid to recycle the water in each unit/equipment.
Effluent generated by cogen plant will be treated in existing sugar Plant having Preliminary and Secondary treatment. In the secondary treatment stage wise activated sludge treatment process will be carried out. Each stage consist of the aeration tank with fixed aerators and secondary clarifiers. The clear effluent from clarifier will be collected in polishing pond and water will be used for irrigation.
Single stage evaporation technology during alcohol concentration & recovery reduces spent wash quantity. Thus, spent wash generation will be minimum. The treated wastewater will be utilized for plant floor washing, make up water for cooling tower, green belt and plantation in the area and captive irrigation. Thus, impact on ground & surface water shall be negligible and zero wastewater discharge scheme involves conversion of spent wash after evaporation to bio-compost using press mud.
11.4.5 Land use
Impact & Management: During construction, some excavation, land filling and development aspects may be needed for leveling of the ground. However, this disturbance be done only on temporary basis. At the end of the construction, the soil will be stabilized at the unpaved areas with the help of plantation activities. More than 33% of the 120.5 acres land owned by ASL has been envisaged to be covered with plantation including green belt. Since the plant species will be capable of checking soil erosion, the soil will be fully stabilised without any adverse change in erosion potential of the area.
During operation phase, the landuse pattern will remain same as constructed/ used. The quality of land & soil degradation can be a matter of concern due to waste water & solid waste disposal on land. The same shall be addressed as follows:
There shall be waste water from the power plant, will be neutralised and used for sprinkling and horticulture. The quality of the water shall be monitored to ensure that it is within norms for disposal land.
The solid waste generation for disposal will be negligible and will be stored in designated areas with impervious bases, thus, the impact on land shall be minimal.
The majority of the solid waste i.e. fly shall be used in composting since it is rich in potash.
11.4.6 Solid waste management
Impact & Mitigation: During Construction phase, there will be development of a shanty town with temporary establishment of residential and commercial nature. Therefore, there will be generation of solid waste to the tune of 0.2 TPD for, say, 500 persons involved
Athani Sugars Ltd.
EIA/EMP for Expansion of Sugar, Distillery & Cogen Plant in Dist. Belgaun, Karnataka 11-9
in construction (& two more family members). These will have to be segregated. The organic matter can be composted and non-biodegradables can be incincerated in the boiler. The recyclable will be sold to recycling vendors although components like paper & plastic serve as high calorific wastes for incineration in boiler.
During operation phase, Bagasse, Press mud and Biological Sludge will be generated form sugar plant. Bagasse will be used in boiler and press mud and biological sludge will be composted.
Boiler ash will be generated from cogen which due to high potash content, will be used with press mud to convert to compost. And yeast sludge which will be generated from the distillery will be composted.
114.7 Ecology
Impact: During construction phase, there will be less negative impacts on terrestrial eco-system comprising birds and animals as the area proposed for construction has less trees. Despite attempts to minimise the cutting / felling to the extent possible, if trees will have to be felled, due permission will be taken from the Forest Department and compensatory tree plantation undertaken within the plant premises. With progressive growth of greenery, terrestrial eco-system will improve in course of time. Presence of water and food wastes during day time will attract some birds and small animals (squirrels, mongoose, etc) towards the site. During operation phase, dust emission from plant and due to transportation, affects the effective photosynthesis by covering the plant/tree leaves by thin dust layer during dry months which however will be washed away in rainy months. There can be roadkill due to traffic, disturbance to birds and animals due to bright light and unusual noise during operation activity and contamination of water bodies on which animals and birds are dependent or contamination of ground water due to effluents and sewage, if mitigation measures are not implemented.
Mitigation: Company has planted several trees around factory premises such as in front of guest house- 50 chiku trees, near cane yard- 70 Gulmor plants, 200 wind trees and 500 mango trees in front of main gate and admin block. 100 ashok trees and 160 tamarind have been planted both sides of road leading to factory. Establishment of greenbelt along the facilities periphery to act as a natural buffer between the surrounding area and the facilities. Construction of boundary or fence along the plant perimeter to prevent wild animals from straying into the plant area and getting harmed.
11.4.8 Socio-economics
There will be additional 300 employment available with the expansion of the plant. Further indirect job opportunities will be on the horizon due to expansion sugar, distillery and co-generation complex. This will result in an increase in income level of the employees, subsequent commercial as well as social infrastructure establishment. Several socio-economic benefits shall be there. Ample power will be available from local grid due to decentralization of power generation and power from grid on no charge basis or low charge basis can be available in this area. This can be an initiative for many units to start. Supplementary type units can be initiated in the area like cattle preservation & protection, poultry, herbal medicinal plants, spices, pickles, papad and other food items, milk producer group co-operative small saving groups.

EIA/EMP for Expansion of Sugar, Distillery & Cogen Plant in Dist. Belgaun, Karnataka 11-10
11.5 ANALYSIS OF ALTERNATIVES
No alternative site was considered for the proposed expansion phase as the plant exist at the present site. The process selection is done based on the following considerations:
i. Least stress on resources including raw materials and utilities
ii. Reduce, Recycle and Reuse of wastes
iii. Least or no pollution from the industry
iv. Least or no risk to human and property
v. Least or no adverse impacts on environment
The technology options for the proposed plant were considered based on efficient utilization of raw materials, fuel and water along with efficiency in power generation. 11.6 ENVIRONMENTAL CONTROL AND MONITORING ORGANISATION
A environmental management department is existing to take care of pollution monitoring aspects and implementation of control measures headed by an EMC coordinator and supported by Environmental Engineer. A schedule has been spelt out for periodical monitoring of the important environmental parameters. The total initial capital investment on environmental improvement works is envisaged as Rs. 673 lakhs while the recurring expenditure during the stage of production is envisaged as Rs. 179 lakhs per year.
11.7 DISASTER MANAGEMENT PLAN
When the full fledged activities of sugar, alcohol & co-generation will gear up, they will have to follow Factories Act 1948 with all amendments till today and any directives from Director Safety, Health & Environment [SHE] will automatically be binding on ASL. In such condition to appoint a qualified Safety Officer is a must & will be an adequate, wise step in such direction. On site and off site disaster control plans and their implementation will be part and parcel of the management & such safety officer. To lessen the probability of hazard to occur & avoid the consequent damage, a disaster management and control plan has to be worked out for whole complex in anticipation to the threat.
To tackle the situation, a site emergency control room will be set up having links with all control rooms of the factory. An upto date communication facility will be provided to control rooms. The emergency organisation shall be headed by emergency leader called Site Main Controller (SMC) who will be factory manager.
11.8 PROJECT BENEFITS
Currently 500 employees are working and additional 300 will get employment during expansion. In addition to these, indirect workers will be several times and the farmers supplying sugarcane is surrounding areas will benefit. For employment, preference will be given to local population for employment in the semi-skilled and unskilled category. Hence, the company has also envisaged various skill-building programmes for locals. Therefore,
