Note: Above said Resin products will be used in captive consumption for manufacturing of laminated sheets (1,75,000 sheets/month) as well as for sale purpose.
M/s. RB Polymers Ltd. has a total land area of 10,407.46 m2. Out of the stated land area approximately 3453.21 m2 is green belt area (approx. 33.18 % of the total land area). The industry has been established since 1992 after obtaining NOC from GPCB. Furthermore, they have been granted Consent (CC&A) from GPCB in the year 1995 for manufacturing Paper based Decorative/Industrial Laminated sheets. Since then they were manufacturing Phenol Formaldehyde Resin & Melamine Formaldehyde Resin for production of 25,000 Sheets/Month. Now they would also like to manufacture new resin product i.e. Urea Formaldehyde Resin in their unit.
The total estimated cost of project is Rs. 5.5 Crore out of which the proposed expansion cost is 35 Lakh. Total budget allocation towards Environmental Management Facilities will be approx. Rs. 40 Lakh after total expansion.
M/s. T. R. Associates (NABET Accredited EIA Consultant) was appointed by M/s. RB Polymers Limited to carry out the Environmental Impact Assessment study for their proposed expansion project.
The products like M.F. Resin, P.F. Resin, U.F. Resin (being synthetic organic chemicals) falls under Category 5(f) as stated in Environment Impact Assessment Notification Published on 14th September, 2006. Further, the location of proposed expansion project is outside the notified industrial estate and not fall in Small Scale Industrial Unit criteria as per the Notification dated 25th June 2014. Hence, project proponent has to obtain the Environmental Clearance from the Ministry of Environment, Forests & Climate Change
(MoEF&CC), New Delhi. As a part of this procedure, Public Hearing is required to be carried out as per the notification as well as the TOR granted to the unit by the Expert Appraisal Committee (Industry-2), New Delhi.
This study of Environment Impact assessment (EIA) is based on studies carried out during the month of October 2018 to December 2018. The environmental parameters (ambient air, water, soil, noise, flora and fauna) selected for study are those, which are likely to be most affected by the proposed project. The study area is defined as an area within 10 km radius from center of the project site.
Salient Features within 10 km radius surroundings area as follows:

2. AIR ENVIRONMENT
The base line Ambient Air Quality (AAQ) status within 10 km study area has been assessed through a monitoring network of 8 AAQ sampling stations during October 2018 to December 2018. Design of network for Ambient Air Quality monitoring locations were decided on meteorology & available infrastructure facilities. The base-
line Ambient Air Quality of the study area was monitored for Particulate Matter (PM10 & PM2.5), Sulphur Dioxide (SO2) and Nitrogen Dioxide (NO2), CO & VOC. The result for the same is given as below:
Analysis of ambient air samples revealed that the Air quality is found well within the prescribed limits of National Ambient Air Quality standards.
The main source of gaseous emission is flue gas emission from existing stack attached to Steam Boiler & TFH. D. G. set is provided as an option.
White coal/ Saw dust/ Wood/ Lignite will be used as a fuel & total fuel requirement after proposed expansion will be 4 MT/Day. Adequate stack height will be provided for proper atmosphere dispersion of pollutants. The probable emitted pollutants will be PM, SO2 & NO2. Cyclone separator followed by Bag Filter and Scrubber is already provided with stack attached to boiler as APCM. Also the unit has provided Cyclone separator as APCM for TFH but after proposed expansion unit will use the same cyclone separator but duct line will be passed through the existing bag filter and scrubber also. Since Diesel is used as a fuel for D. G. Set (back–up system) the flue gas emission will also be well within prescribed norms and there is no need of any air pollution control measures for D. G. Set.
3. WATER ENVIRONMENT
Analysis of ground water and surface water samples revealed that it is suitable for domestic activity including agricultural activity. Ground water quality in the area meets the Water Quality Standards (IS 10500) for drinking water except for parameters like Turbidity, EC and Total Hardness whereas surface water quality in the area meets the Water Quality Standards (IS 10500) for drinking water except for parameters like pH, COD, BOD and Total Coliform.
The total fresh water requirement for the project after proposed expansion will be 27.3 kl/day. Out of this said fresh water quantity 3.3 kl/day will be used for domestic purpose, 20.7 kl/day will be used for industrial activities and 3.3 kl/day will be used for greenbelt development purpose. The required water will be obtained through Borewell.
B. Wastewater Generation and its Disposal
The total generation of domestic wastewater after proposed expansion will be 2.7 kl/day. The domestic wastewater generated will be treated in STP and treated water will be reused in gardening.
The total industrial effluent generation after proposed expansion will be 6.2 kl/day, which will be from boiler blow down, cooling tower blow down, process, scrubber and washing. Industrial effluent will be collected in Collection cum Neutralization Tank for neutralizing the effluent characteristics. After that, wastewater will be given Chemical Oxidation Treatment. After completion of chemical treatment, effluent will be taken to Nutch filter/Filter Press for sludge separation. Separated dried sludge will be collected, stored and disposed of at approved TSDF site. Filtrate water from Filter Press will be taken in the holding tank and then effluent will be evaporated using Evaporator through heat energy. Therefore, no effluent will be generated and the stated process would be a ZERO DISCHARGE process.
4. LAND / SOIL ENVIRONMENT
During operation activity the impact of air, water and solid waste pollution on soil causes direct / indirect effect on soil.
As all necessary air pollution control steps are provided and based on the results of the dispersion model for the Ground Level Concentrations of various pollutants after proposed expansion project, there will not be any adverse impact of air pollution on soil.
It may be noted that there will be no disposal of untreated effluent on land. So, there will be no adverse effect on land / soil due to water.
All necessary control steps are provided for handling, storage and disposal of solid/hazardous waste generated from the plant. Thus, there will not be any significant impact of solid/hazardous waste on the soil environment.
5. NOISE ENVIRONMENT Noise level was recorded at 8 locations within the study area to provide the baseline data to describe the existing situations.
From the above Noise results it will be concluded that Noise levels are found within the permissible limit except Iyava location due to continues transportation activity.
6. SOCIO-ECONOMIC ENVIRONMENT An assessment of socio-economic environment forms an integral part of an EIA study. Socio-economic environment – demographic & related socio-economic data was collected from District Census Handbook to assess socio-economic status of the study area.
For proposed expansion project activity, total 30 nos. of skilled and unskilled employees/workers will be required. The indirect employment will be generated by way of transportation, shopkeepers and other casual employment for many people.
Local people will be given preference wherever found suitable for all the jobs in the plant. Economic status of the local people will improve due to the increased business opportunities, thereby, making a positive impact. Educational, medical and housing facilities in the study area will considerably improve.
7. ECOLOGY & BIODIVERSITY
EB study reported a total of 130 plant species, 7 herpetofauna, 38 birds and 6 species of mamamals from the buffer zone of RB POLYMERS LIMITED. However, no threatened biodiversity reported with highest density or richness from the core and buffer zones of the study area. In addition, no true multi species forest type was recorded in the vicinity of the two-five kilometer radii in and around the project site. It clearly indicates the low productive potential of the terrestrial ecosystem. Since the project associated activities do not
required any additional land, the terrestrial ecosystem is considerably free from the project related impacts.
8. SOLID WASTE MANAGEMENT
The main hazardous waste generation is ETP Sludge + Evaporation Residue, Used Oil and Discarded Plastic Bags/Drums.
ETP Sludge + Evaporation Residue is disposed off at approved TSDF site. Used Oil is reused within premises as a lubricant or sold to registered recycler. Discarded Plastic Bags/Drums are sold to authorized vendor. The same methods of solid waste management will be followed after proposed expansion project.
The unit has provided isolated area for the storage of hazardous waste. Thus, hazardous waste management system provided by the unit will be adequate and there will not be any major impact on the environment due to hazardous waste.
9. ENVIRONMENTAL MANAGEMENT PLAN
An Environmental Management Plan has been prepared for mitigation of the adverse impacts. An Environmental Management Cell is formed for effective implementation of Environmental Management Plan.
The Environmental Management Plan describes in brief, the management’s plan for proper and adequate implementation of treatment and control system for pollutants and for maintaining the environment. It also includes maintenance of green belt, proper safety of workers, environmental monitoring plan, rain water harvesting, fire protection system and measures etc. The same methods of environment management plan will be followed for proposed expansion project.
10. ENVIRONMENT MONITORING PROGRAM
Monitoring of environmental factors will enable us to identify the changes in the environmental impacts at various locations and their mitigative measures. To ensure the effective implementation of the EMP, monitoring of ambient air quality, stack emissions, analysis & monitoring of water environment and noise level will be carried out as required / specified by statutory authority. The same methods of environment monitoring will be followed for proposed expansion project.
11. RISK ASSESSMENT
Risk analysis and study have been carried out for identification of hazards, selection of maximum credible scenarios, risk mitigation measures etc. All the hazardous chemicals are stored and handled as per MSDS guidelines. Personal protective equipment’s are
provided to the workers. The same will be continued for the proposed expansion project.
12. GREEN BELT DEVELOPMENT
A greenbelt of approximately 3,453.21 m2 is developed within the project site to minimize the air pollution, noise pollution, balancing eco-environment, soil erosion / protection etc. Greenbelt area is 33 % of the total plot area.
13. PROJECT BENEFITS
The proposed expansion project will become beneficial to the surrounding area or community in terms of infrastructural development, social development, employment and other benefits.
The proposed expansion project has a potential for employment of skilled, semi-skilled and unskilled employees during operation phase. A total 30 persons (14 persons (existing) +16 persons (proposed)) is likely to get employment due to the proposed expansion project. The project gives 1% of project expansion cost for socio-economic development activities in surrounding villages which will be continued further.
14. CONCLUSION
Negligible impacts will occur on air quality. However, all the necessary air pollution control measures will be provided.
No ecological damage will occur. No adverse impacts will occur on water environment. Local employment opportunities will increase. Various other environment parameters like Forest/ National Park/ Sanctuary
and Religious / Historical Places will not be affected. Environment Management Plan has been formulated to control all the pollutant
parameters and Environment Management Cell has been set-up to ensure that these parameters do not exceed the norms set out by the concerned authorities.
After commissioning of the proposed expansion project the Environmental Management Cell will take care of all the pollution control measures.
It can be concluded on a positive note that after the implementation of the mitigation measures and environmental management plan during the construction & operational phase, there will be negligible impact on the environment due to the proposed expansion project.
NA permission has been obtained for this project. The site is already constructed & in operation.

2.6 Manufacturing Process
Manufacturing processes of Phenol Formaldehyde Resin, Melamine Formaldehyde Resin and Urea Formaldehyde Resin including their reaction chemistry, mass balance and process flow diagram are described here below:
2.6.1 Phenol Formaldehyde Resin
A. Manufacturing Process
Take required quantity of Phenol and Formaldehyde (37%) in the reaction vessel and start steam heating until the temperature reaches at 58 °C to 60 °C.
Temperature will increase up to 90 °C. Once the temperature reaches up to 90 °C, cut the steam supply. Reflux process will start at this point to achieve required water tolerance.
After achieving required water tolerance, start cooling to decrease the temperature up to 60 °C. Once the temperature reaches 60 °C, stop cooling and start heating for distillation process for required quantity of resin.
After achieving required amount of resins, add Methanol for viscosity adjustment and start cooling to obtain final product. Final product will be checked for the properties like viscosity, pH, gel time etc.

2.6.2 Melamine Formaldehyde Resin
A. Manufacturing Process The Formaldehyde (37%) is charged into reaction vessel and its pH is raised up
to 8.5 – 9.0 by adding NaOH solution. After that Melamine is charged into vessel thoroughly to maintain the pH up to
8.5– 9.0. Heat is supplied and temperature is raised up to 82 °C. Maintain 82 °C at pH 8.5 – 9.0 for 90 minutes till the precipitation is observed.
Check the flow time in hot condition with B4 cup till it is around 14.5 sec. Then take reaction at pH 9.0 by adding NaOH solution. The mixture is cooled at 60 °C and cooling is continued up to 40 °C by circulating cold water.
Finally check the viscosity, tolerance, pH, turbidity etc. to obtain the desired product property.

2.6.3 Urea Formaldehyde Resin
A. Manufacturing Process The polymerization reaction of Urea Formaldehyde Resin takes place in two
stages. The first stage is an addition polymerization in which Urea & Formaldehyde (37%) undergo addition reaction, which takes place in neutral condition at elevated temperature i.e., 95 °C to 100°C.
Methyl Urea formed in the first stage is allowed to reach further by lowering pH 4 to 6 where reaction takes place faster and leads to the formation of long chain polymer.
The reaction is allowed to proceed further up to the desired viscosity and the reaction is arrested midway by raising the pH of the resin solution to 7.5 to 8.0 and then the reaction is cooled down to the room temperature and stored in sealed container.
Check viscosity, tolerance, pH, gel time of the required batch of the resin.

Fly ash generation has been calculated considering maximum ash generation scenario considering the use of Lignite.
Ash content in Lignite : 10.41 %
Total Ash generation = 0.1041 x 4.0 MT/day
= 0.4164 MT/day
Considering 50% Ash to be collected from bottom,
Bottom Ash = 0.5 x 0.4164 MT/day
= 0.2082 MT/day [A]
Considering 50 % Ash to be carried away with flue gas as fly ash which will be further trapped in dust collector (Efficiency: 60 %) and bag filter (Efficiency: 90 %)(40% left out)
Fly ash trapped in Air pollution control units = 0.6 x (0.5 x 0.4164) + 0.9 x {0.4 x (0.5 x 0.4164)}
= 0.1998 MT/day [B]
Total Maximum Ash to be generated using coal = 0.408 MT/day [A + B]
Total Ash to be generated will be stored into silo with proper care and sold to bricks manufacturer.
2.9.4 Noise & Vibration
Noise is generated sometimes due to the operation of D. G. set in the existing project. However, D. G. set is kept as standby and there is no other source of noise and vibration from the manufacturing activity except plant machineries. However, unit has taken following adequate precautionary measures for noise and vibration control;
Latest technology based low noise D.G. set with acoustic enclosures is installed. All the vibrating parts are checked periodically and serviced to reduce the noise
generation. The equipment, which generates excessive noise, is provided with enclosures.
Proper and timely oiling, lubrication and preventive maintenance is carried out for the machineries and equipments to reduce noise generation.
Ear muffs/ earplugs are also provided to the workers working under high noise area to minimize the adverse effect on the health.
To reduce the noise generation during the transportation activities; the transport
contractor is instructed to keep vehicle periodically serviced and maintain as per the requirement of latest trend in automobile industry. Only those vehicles with PUC’s are allowed for the transportation.
The transport contractor is also informed to avoid unnecessary speeding of vehicles inside the premises.
Noise monitoring is done regularly at prominent places in the plant. The existing greenbelt area helps to prevent the noise pollution outside the
premises.
2.9.5 Odor Control Plan
Odor can be defined as “perception of smell”. Odorous substances emitted from industrial sources can be due to both inorganic and organic gases and particulates. Many odorous compounds result from process activities. There exists perceived connection between odors and their health effects. Thus, it is important to propose mitigation measures for minimizing odor nuisance. [2] Odor sources due to proposed expansion project are given in the Table 2.25.
Table 2.25 – Details of Probable Odor Sources & Control Measures
Probable Odor Sources Control Measures Emissions from formaldehyde storage area Ensuring that storage tanks are always in
closed condition and it is transferred to process area through leak proof pipelines.
Wastewater treatment plant Ensuring that the operation is being/will be carried out under the best management practices.
Emissions from phenolic resin and melamine resin storage areas
Ensuring that resins are stored in closed tanks and suction hoods are provided above the resin storage tanks while it is being used for manufacturing of laminated sheets.
2.9.6 Potential Impacts & Mitigation Measures
Brief description of potential environmental impacts and mitigation measures is provided in the Table 2.26 below.
3.1 Introduction Preparation of Environmental Impact Assessment (EIA) report requires identifying potential environmental impacts due to the proposed expansion of the project and that needs a datum on which the impact identification can be done. For generating baseline conditions, it is necessary to collect primary and secondary data for different environmental components like air, noise, water, land, socio-economic factors, ecology & biodiversity which will be affected by the operation of any project activity. The objective of establishing baseline conditions is “To compile authentic and relevant information on the environmental components in the study area, which are likely to undergo change due to the project-related activities in both the short as well as long term and have potential of causing environmental impacts.” This necessitates ensuring focus on capturing the information which is relevant, appropriate, authentic and credible. The elaborate monitoring for generating baseline scenario is generally preceded by a well-planned desk work and reconnaissance survey of the study area by the concerned functional professionals in consultation with the EIA team leader and proper documentation of the observations/findings. An effective methodology is important for baseline data collection and impacts prediction to develop an efficient Environmental Management Plan. In this regard, it is important to understand the ground realities of the core zone and buffer zone by the experts involved in baseline studies. Accordingly, a team of experts visited the proposed expansion project site to understand the site surrounding and possible impacts from the activities of the proposed expansion project. The EIA coordinators in consultation with the respective functional area experts selected the sampling locations as per the TOR prescribed by the EAC, New Delhi. An attempt has been made to collect the relevant and authentic information about existing environmental conditions concerning the below mentioned six major environmental attributes:
Air Environment Noise Environment Water Environment Soil, Landscape and Visual Environment Ecological Environment
Social Environment Subsequently, the field monitoring was undertaken during October to December, 2018 by the team of T. R. Associates’ Laboratory. The collected data are analyzed and interpreted. The same is represented below under various sections. 3.1.1 Baseline Study Area To carry out Environment Baseline Monitoring and to generate baseline environmental data, study area of 10 km radial distance from existing project site has been selected. Base line data of ambient air quality, water quality, land use & land cover, topography, ecology as well as socio economic status was collected for study area of 10 km. 3.1.2 Methodology of Baseline Study For the generation of baseline data, guidelines proposed by MoEF&CC as well as generic TORs issued by Expert Appraisal Committee (EAC) of MoEF&CC has been taken into consideration. Relevant secondary data available for different environmental components were collected and analyzed. Baseline planning has been described in Table 3.1 in brief.

3.2 Air Environment Dispersion of different air pollutants released into the atmosphere have significant impacts on the neighborhood air environment of an industrial project and forms an important part of impact assessment studies. The ambient air quality status with respect to the study area of 10 km radius from the plant site will form the baseline information over which the predicted impacts due to the proposed expansion of plant can be super imposed to find out the net (final) impacts on air environment. From the final impacts a viable Environmental Management Plan (EMP) can be prepared based on the impact statement for the air environment. The baseline status of the ambient air quality can be assessed thorough scientifically designed ambient air quality monitoring network. The design of monitoring
network in the air quality surveillance program has to be based on the following considerations.
Meteorological conditions on synoptic scale. Topography of the study area. Representation of regional background levels. Representation of plant site. Representation of cross sectional distribution in the downwind direction. Inclusion of major distinct villages to generate the baseline status.

Also stack monitoring of existing unit was carried out. Results of it are presented below in Table 3.9. AAQ results are attached as Annexure – 3.
3.3 Noise Environment Noise can be defined as any sound that is undesirable because it interferes with speech and hearing, and is intense enough to damage hearing, or is otherwise annoying.
3.3.1 Sampling Methodology
Pre-project noise levels have been monitored at different points within the study area using on the spot measurement device manufactured by LUTRON SL 4033-SD having range of 30 to 130 dB (A).
Equivalent sound levels were then calculated from the recorded values of noise levels for the day and night time. Then Leq values of noise levels are compared with the noise standards prescribed by CPCB2.
3.3.2 Sampling Frequency
Noise levels of selected locations were monitored on hourly basis for 24 hours, once during the study period.
3.3.3 Selection of Monitoring Locations and Results
To study noise levels in 10 km study area, sensitive receptors were identified and noise monitoring was carried out at a distance more than 100 m from the identified location. As this is existing project site, noise monitoring was carried out within the industry premises and other 7 locations keeping in view various other activities such as; residential activities, industrial activities and traffic pattern.
Selected noise monitoring locations (Figure 3.6) along with justification for selection have been described in Table 3.10 below. Recorded noise levels are presented in Table 3.11.

The minimum noise level measured in the study area was 51.95 dB (A) in day time at Khoda village and 41.13 dB (A) at Motipura village in night time. The maximum noise level measured in the study area was 67.7 dB (A) in daytime and 61.9 dB (A) in night time, both at project site. Based on the noise monitoring results it can be concluded that in day time noise levels are higher than the permissible limit at Iyava village where transportation
activities are on higher side. Also, during night time noise monitoring results are slightly higher than the permissible limit at Iyava village which is also due to vehicular movements during night time. 3.4 Water Environment Studies on Water Environment aspects of ecosystem is important for EIA studies to identify sensitive issues and take appropriate action by maintaining ‘ecological homeostasis’ in the early stages of development of the project. The objective of this report is to define the present environment in which the proposed expansion is to occur, to evaluate all possible eventualities, to ensure that all negative impacts are minimized, and to demonstrate that proposed expansion project has been appropriately announced to all interested parties so that their concerns can be considered. Water of high quality is essential to human life, and water of acceptable quality is essential for agricultural, industrial, domestic and commercial uses. So, water quality studies have been carried out in the study area to understand the availability of water resources, possibility of water contamination and existing water quality.
3.4.1 Sampling and Analysis Methodology
Water samples were collected from 16 locations; out of which 8 were from surface water sources and other 8 were from ground water sources. They were analyzed for physico-chemical, biological and microbiological parameters. Parameters like pH, Temperature and DO were analysed onsite.
For sampling, preservation and transportation of water samples; guidelines prescribed by CPCB3 were followed. Other water quality parameters were analysed as per the procedures specified in APHA [1] / IS 3025.
Method of Water Sampling
Washing the bottles/cans with distilled water prior to the sampling. Before collection of water, the bottles/cans are again washed 2-3 times with the same water. For surface water, bottles were lowered to a minimum depth of 30 cm below water surface. At each point different sets of water samples were collected to cover all the parameters. Proper attention is taken into proper numbering at the site. Sterilized bottles were used for the samples that are to be analysed for bacteria.
3 Guidelines for Water Quality Monitoring (MINARS/27/2007-08)
Civil supply water pipeline taps are sterilized before collection for bacteriological analysis. Parameters like pH, conductivity and temperature were analysed in the field conditions and
the results were reconfirmed after getting to the laboratory. DO is fixed in the field itself. Appropriate preservatives are added, depending upon the elements to be analysed and marked accordingly [IS: 3025 (part I) 1987].
All the water samples collected in the ice box were immediately transported to the laboratory and froze at < 5 °C for analysis.
Field observations were noted in the field notebook. As far as possible photographs were taken at almost all sampling points.
3.4.2 Sampling Frequency
The water quality sampling and survey was carried-out once during the study period in October-2018, within the 10 km radius from the project site.
3.4.3 Selection of Monitoring Locations and Results
Locations for SW and GW monitoring were selected based on the guidelines for water quality monitoring issued by CPCB in 2008. Surface Water
Google image showing surface water monitoring locations and photographs showing SW sampling are attached as Figure 3.8 & Figure 3.9 respectively. Table 3.12 shows all the locations selected for SW sampling & monitoring.

3.4.4 Interpretation of Water Quality Results Surface Water
The physico-chemical and microbiological characteristics of surface water is summarized in Table 3.13.
pH of water at Chekhla pond, Gadhiya lake and Goraj pond are found slightly higher than the permissible limit.
Values of COD & BOD at Bol pond are found at higher side w.r.t CPCB standards. That may be because of decay of benthic organisms.
Overall, water quality of all the ponds is found good for irrigation purpose. Water of some locations may be suitable for drinking and domestic activities after necessary treatment.
Canal near Vasna Iyava and Gadhiya Lake has odor problem. The value of total coliform exceeds the tolerance limit at Bol pond & Iyava pond. Iyava pond was having mild eutrophication which may be due to runoff from
agricultural fields.
Ground Water
The physico-chemical and microbiological characteristics of ground water is summarized in Table 3.15.
Turbidity is found to be higher than permissible limit at Vasna Iyava and Chekhla. Total hardness is found higher than the permissible limit at Chandrasan, Vasna Iyava
and Sanand. Electrical conductivity of GW samples varies from 806 μS to 2618 μS, which indicates
high mineralization of ground water. These water samples can be classified as hard. So, it needs to be softened before domestic or industrial use.
Overall, water quality of all the ponds is found good for irrigation purpose and it may also be used for domestic and drinking purposes after necessary treatment.
3.5 Soil Environment Natural soils are the product of physical and chemical weathering of rocks. The physical properties are formed during the course of formation and the subsequent existence is depending upon the topography, hydro meteorological condition and human interference. Soil characteristics of a terrain are more important aspects since they play a major role in ground water recharge and meet the basic needs of all agricultural production.
3.5.1 Soil Type
Medium black soils are found in some areas of Sanand taluka which are suitable for growing bajri, jowar and cotton. Goradu soils vary from fertile brown to sandy loam and are found in parts of Sanand taluka which is mostly fertile and responds very well to irrigation and manuring. Practically all kinds of crops can grow on this soil. Kyari soils are found in several parts of Sanand which is the most fertile soil with very good moisture and retentive capacity. Well known varieties of paddy such as Pankali, kamod, Jirasar, Sukhvel, Sutarsal and Basumati are grown on this soil4.
3.5.2 Sampling Methodology
Disturbed soil samples were collected with the help of the rotary cuttings and bailers and also from split spoon samplers. Un-disturbed soil samples were collected using thin walled tubes. Soil samples were collected in such a way that structure and moisture content of the soil do not get altered. In accordance with IS: 2720, split samples were carefully extracted from the samplers.
More Attention was paid to collect adequate amount of composite soil samples for analysis. The samples were packed in dependable, waterproof containers and marked accurately and distinctly. All the soil samples and core boxes were carefully transported to the testing laboratory. Soil sampling and analysis has been done as per the Indian Standard IS – 2720.
3.5.3 Sampling Frequency
The soil sampling was carried-out once during the study period in October-2018, within the 10 km radius from the project site.

The results of soil analysis along with testing procedure used are tabulated in Table 3.17.
3.5.5 Interpretation of Soil Quality Results Interpretation of the physico-chemical characteristics of soil are summarized in Table 3.17 is described below:
The soil pH of project site, Goraj and Sanand villages indicate that the soils are moderately alkaline. The soil pH of Chharodi, Khoda. Anadej, Chharal and Iyava villages reveal that the soils are highly alkaline.
EC values of all soil samples except project site are normal & moderate. Organic carbon content of all soil samples is high (0.82 to 2.25 %). Available P2O5 is found to be low in all soil samples. The soils of project site, Goraj, Iyava and Khoda villages are having low K2O content,
soils of Chharodi, Sanand and Anadej villages are having medium K2O content and soil of Chharal village is having high K2O content.
Calcium & magnesium salts are more than critical levels in all soil samples. The WHC is very good of all soil samples because of black clayey soil. As organic matter content in all soil samples is high, potential of soil to supply nitrogen
to plants is high. CEC is pH dependent. As pH of soils is moderate to high, CEC is considerably more. As soils of all villages including project site is moderate to highly alkaline in nature,
gypsum application is recommended to remove excess content of sodium to make soil neutral in reaction.
Rapid urban growth and its continuous expansion around Sanand Taluka, Dist. Ahmedabad has created problems related to water supply. Sewerage/Effluent disposal is leading to ground water depletion and pollution. The present report incorporates hydrogeology and ground water scenario based on the scientific information with special reference to Recharge Activity in Sanand Taluka to envisage appropriate remedial measures keeping environmental impact of Sanand Taluka development in view.
General Information of Taluka - Sanand
Total number of villages = 67 Total area of Taluka in Sq. Kms.= 800 Saline area = 240 Sq.Kms. Fresh water area = 460 Sq.Kms. Hard rock area = NIL. Aluminum area = 800 Sq.Kms Feasibility =Deep Tubewell Quality of Groundwater = Potable water & Partly Saline
Climate & Rainfall
The climate of the area is semi-arid and is characterized by hot summers and general dryness except during the South West monsoon between the months June and September. There is a meteorological observatory at Ahmedabad managed by IMD. May is the hottest month with mean daily maximum temperature of 41.3 °C and the mean daily minimum temperature of 26.3 °C. The maximum and minimum temperatures recorded at Ahmedabad are 47.8 °C (1961) and 2.2 °C respectively. The area has semi-arid climate with drought frequency of 34%.
Dependable Rainfall = 857 mm = 0.857 m Last 30 year average Rainfall = 778 mm
Geology
The area forms part of North Gujarat Alluvial Plain with elevations ranging from 40 to 50 m MSL. The area is under lain by post Miocene alluvium comprising sand, gravel, silt and clay. The alluvium is about 400 m thick under lain by tertiary formation. The alluvium mainly
consists of palaeo deltaic, fluvial and Aeolian sediments, comprising alternate bands of fine to course grained sand, gravel and yellowish brownish sticky clay. Hydrogeology
The lithological logs of exploratory bore holes, electrical logging results by govt. agencies in and around Sanand Taluka have been studied to understand the subsurface geology and the aquifer system. These bore holes have penetrated the thick sequence of post Miocene sediments down to 300+ m depth.
The hydro geological cross sections have been prepared by CGWB to study the subsurface geology and aquifer system in the area. It is revealed that there exists multilayered aquifer system, within a depth of 300+ m below ground level.
Drainage Pattern
The area has a drainage pattern which is of the parallel and trellis type and which is controlled by the topography and structure and tectonics of the region. All the small streams flow from the higher grounds and meet ultimately Sabarmati River which flow from South-North direction to South-West direction near project area. The area drainage ultimately meets with Gulf of Khambhat.
Area has diverse landscape made up of alluvium plain. Two-three rain water ranges are passing from nearby project area. The terrain slope is towards South in the North and towards West in the South. Due to terrain constraint it is necessary to adopt proper soil conservation and sand water development and management practice for w/s in sustained basis. Because of short span of monsoon season and limited storage capacity and rapid cut flow for alluvium aquifers, it is needed to provide ground water recharge facilities to supplement its withdrawal at a time of summer.
As various components of the hydrologic system - catchment runoff, base flow and ground water are integrated at the level of river basins, river basin should be the unit of governance and management of water resource. Such a system of governance will ensure integration of physical sustainability consideration and the social, economical and environmental consideration in water resources management planning which ultimately results in good governance. Depth of Ground Water
Shallow aquifer (Phreatic) development (up to 30 m depth) in the area is limited due to rapid urbanization, inferior quality and low yields. Depth of water level in these tube wells
ranges from 10 to 20 m. Yield of wells is moderate and quality of ground water is variable and ranges from fresh to saline. 3.6.2 Feasibility of Source at Iyava, Taluka: Sanand Surroundings of Sanand Taluka is checked on ground water prospect map, prepared by National Remote Sensing Agency, Dept. of Space, G.O.I, Hyderabad; map sheet no 46A08 for feasibility of source. The details are as under.

The land-use & land cover map of the 10 km radius study area from the project site has been prepared using Sentinel Satellite image procured from NRSC (National Remote Sensing Centre), Hyderabad. Land use pattern of the study area as well as the catchment area was carried out by standard methods of analysis of remotely sensed data and followed by ground truth collection (Benchmark) and interpretation of satellite data. The outcome of land use study has been presented below in subsequent table and figures. The data was processed through Q-GIS Software tools available with ESRI Package. The land use map of the 10 km study area is presented in Figure 3.15.
3.7.2 Land Use & Land Cover Classification Results
The present Land use/Land cover map for the proposed project activity is prepared by current vintage of satellite image. This report thus will enable assessing the impact on land use pattern in the study area due to the proposed project activity.
(A) Data Used
Current vintage data of Indian Remote Sensing satellite sentinel image FCC (False Color Composite) has been used for preparation of Land use/ Land cover thematic map of study area. Survey of India toposheet as a reference map on 1:50,000 scale has been used for preparation of base layer data like road, rail network, village and mine site and for geo referencing of satellite image.
Technical Details Satellite Image - Sentinel Satellite image. Satellite Data Source - NRSC, Hyderabad Software Used - Earth Resources Data Analysis System (ERDAS) Imagine and Q-Gis.
(B) Methodology
Land use / Land cover map preparation, Base map creation; Geometric and Radiometric correction of satellite image has been processed using ERDAS Imagine Software.
Salient features of the adopted methodology are given below: Acquisition of satellite data. Preparation of base map from Survey of India toposheets.
Data analysis using visual interpretation techniques. Ground truth studies or field checks. Finalization of the map. Digitization using heads up vectorisation method. Area calculation for statistics generation.
(C) Interpretation of Remote Sensing Data
Satellite images are composed of array of grid, each grid has a numeric value that is known as digital number. Smallest unit of this grid is known as a pixel that captures reflectance of ground features represented in terms of Digital number, each representing specific land features. Using image classification technique, the satellite data is converted into thematic information, map based on the user’s knowledge about the ground area. Hybrid technique has been used i.e. visual interpretation and digital image processing for identification of different land use and vegetation cover classes based on spectral signature of geographic feature.
Spectral signature represents various land use classes. Image interpretation keys are developed based on image characteristics like color, tone, size, shape, texture, pattern, shadow, association etc, which enables interpretation of satellite images for ground feature. Training sites are then assigned based on their spectral signature and interpretation elements. Using image classification algorithm land use map is generated.
A total of seven land use/land cover classes have been demarcated in the study area following Level I, II and III classification (Table 3.19). A thematic map suitable for 1:25,000 scale map generation incorporating these classified categories has been prepared and considering that the area of the project is considerably small a large scale map is prepared (Figure 3.15). The area as a whole represents plain area with very gentle sloping to nearly level area & to the north of area flowing from south to north and it is also observed that the major stream (Iyava reservoir) are linked with these two main drainage that debouche into the Gulf of Khambhat. Medium level industrial zone covered for 15.71 sq. km., the total land area of scrub land covered 17.09 sq. km. and 261.00 sq. km. area covered under agriculture land as well as agriculture plantation 0.32 sq. km. has developed mainly in the area adjacent to the rivers.
The adjoining area of project site is totally agricultural land including Kharif, Rabi and Summer crop, constitute the dominant category of land use covering as much as 261.00 sq. km. of the total area. Active river canal forming the perennial water body together with the numerous open & wastelands form a major and minor land cover category. Active river and its tributaries flowing into it cover about 2.71 sq. km. of the total project area. Due to large
seasonal variation in discharge of these rivers, the area coverage of this category various in space and time. The consistently shifting nature of the river and consequent bank migration has resulted in large uncultivated & rural settlement along the active plain area towards the site location. These areas (4.65 sq. km.) are village pond and waterbody in the development area of the project site and are located within the uncultivated land areas significant distribution. The land use for settlement is mostly confined to the ‘rural and urban settlement’ (built up-rural) 8.74 sq. km. and land without scrub feature 2.88 sq. km. of the total area & as such there is no current fallow land because the satellite used is of March month when most of the crop is towards senence or maturity.

The topographic feature & drainage pattern of the study area have been studied from SRTM3, 2008 data having resolution of 3 arc seconds. The toposheet have been analysed using QGIS application to generate the contour line at interval of 10 kms considering one elevated area in the study region. Further, the digital elevation data have been analysed to determine the slope & elevation profiles of the each individual villages of the study area as well as whole study area to ascertain the landform of the villages and study area.
It has been observed that the major area of study area is levelled plain to nearly level with small slopes. Two areas in the study region have been noticed with considerably gentle slope near Village Iyava making the landform of small slopes indicating small plain with the elevation profile. Over all slope direction of the study area is noticed towards south to north. The maximum elevation and higher slope is found near northern part of Vasna Iyava and Khoda village where a medium height is situated. The generated streams indicated that the most of the area are covered by Iyava reservoir flowing East to North. Topography of the area is characterized by dominating plain area with very gentle sloping to nearly level area.
Digital Elevation Model
Digital Elevation Models are data files that contain the elevation of the terrain over a specified area, usually at a fixed grid interval over the "Bare Earth". The intervals between each grid points will always be referenced to some geographical coordinate system. This is usually either latitude-longitude or UTM (Universal Transverse Mercator) coordinate systems. The closer are together the grid points, more detailed information will be in the file. The details of the peaks and valleys in the terrain will be better modelled with small grid spacing than when the grid intervals are very large. Elevations other than at the specific grid point locations are not contained in the file. As a result peak points and valley points not coinciding with the grid will not be recorded in the file. For practical purpose this "Bare Earth" DEM is generally synonymous with a Digital Terrain Model (DTM)
Data Used
DEM Data: Shuttle Radar Topographic Mission (SRTM) data Software Used: ERDAS Imagine & Q-GIS.
Physiography and Drainage Pattern
Topography of the area is characterized by very gentle sloping area to level to nearly level. An Iyava reservoir drains through the study area and merges into Gulf of Khambhat.
In order to understand the status of biodiversity (flora and fauna) in different habitats in and around the RB Polymers Ltd. project area, the field work was carried out during October 2018.
3.8.1 Macro Level Approach- Secondary Data Collection
Collection and collation of project related secondary information. Rapid survey of the project area to identify existing major habitat types within it
(i.e., Wilderness area, Agriculture, Wasteland and Wetlands, i.e., village ponds, tanks, reservoirs and riverine).
3.8.2 Micro Level Approach- Field Data Collection
Micro level field approach involved mainly the survey-based primary data collection on various biodiversity components of the project objectives.
The field data collection mainly included biodiversity assessment of different life forms of floral species such as; trees, shrubs, herbs and grass.
Faunal diversity was also assessed by inventorying the major group like herpetofauna, birds and mammals.
3.8.2.1 Floral Status
Status of floral diversity was assessed in representative habitats of each type like; wastelands which include: open scrub forest and Prosopis juliflora thickets, semi-wilderness area, agricultural hedge, near human habitation, plantation, stream and river beds and wetlands (inland).
3.8.2.2 Faunal Status
Herpetofauna
Status of herpetofauna was assessed using Intensive Time Constrained Search Method covering different micro habitats (Welsh, 1987, Welsh and Lind 1991). This intensive search was made in different habitat types randomly selected. Birds
Avifaunal status was assessed both in terrestrial and aquatic habitats. Total count or flock count method was adopted to assess the status of aquatic birds in the existing water bodies (Sridharan 1989 and Bhupathy 1991). Point count method was used to assess the status of
terrestrial birds (Bibby et al., 1992 and Hutto et al., 1986). The second technique adopted was area search method (Dieni and Jones 2002), a time area constrained survey technique that has been widely and commonly used in several bird monitoring programs. Mammals
Status and distribution of different mammal species was quantified using Direct count Vehicle transects (travelling between the sampling location) (Burnham et al. 1980) and indirect evidences within the survey areas (Rodgers 1988 and Sale and Berkmuller, 1988). Indirect evidences like, Pellet, dung, tracks (Thommpson et al 1989, Allen et al 1996), scat count (Henke and knowlton 1995) and other signs were enumerated using standered method for nocturnal species (Daniels 1992). Presence of different faunal species was also substantiated by interviewing the local people and experts with pictorial representation.

Biodiversity Status - Fauna A. Herpetofauna
The buffer zone area covering 10 km radius reported overall 7 species belong to 7 genus and 6 families. Within the buffer zone, among the habitats types maximum of five species were recorded along the villages (discussed and collected information from local people) followed by three species in agriculture areas and two species in other habitats (Table 3.25).
Table 3.25 - Taxonomical Status of Herpetofauna Family & Species name Common and Local Name IUCN Status
Status of terrestrial and aquatic birds was assessed during latter part of winter and summer and reported a total of 38 species belongs to 37 genera and 31 families in the buffer zone of study area (Table 3.26). Habitat specific abundance resulted more contribution was from agriculture and habitation areas; and there is no any permanent aquatic habitat existing within it, therefore during the study period aquatic avifauna was reported from the nearby wetland and reservoir.

3.8.4 Conclusion
This study reported a total of 130 plant species, 7 herpetofauna, 38 birds and 6 species of mamamals from the buffer zone of RB POLYMERS LIMITED. However, no threatened biodiversity reported with highest density or richness from the core and buffer zones of the study area.
In addition, no true multi species forest type was recorded in the vicinity of the two-five kilometer radii in and around the project site. It clearly indicates the low productive potential of the terrestrial ecosystem. Since the project associated activities do not required any additional land, the terrestrial ecosystem is considerably free from the project related impacts.
3.9 Socio Economic Environment 3.9.1 Introduction
Any developmental activity will influence the socioeconomic conditions of the population in the region and thus the Quality of Life (QOL). Socioeconomic survey is necessary in EIA/EMP report preparation to predict the changes on social and economic status. Hence baseline data for demographic characteristics, education, health, amenities and sensitive locations existing in and around the project area have been studied in the study area. For the study of socioeconomics 10 km radius around the site is selected.
The study area is mostly agricultural land. The major language is Gujarati, Hindi and English with an accumulation of different cultures like the Hindus, Muslims and the Christians. It is the centre of Gujarati cultural activities and diverse traditions of different ethnic and religious communities

3.9.2 Socioeconomics
Village/town wise population, households, Occupation and Literacy status have been collected based on Census, 2011 in the following aspects:
A 'household' is usually a group of persons who normally live together and take their meals from a common kitchen unless the exigencies of work prevent any of them from doing so. Persons in a household may be related or unrelated or a mix of both. However, if a group of unrelated persons live in a census house but do not take their meals from the common kitchen, then they are not constituent of a common household. Each such person was to be
treated as separate households. The important link is finding out whether it was a household or not was a common kitchen. There may be one member households, two member households or multi-member households.
There are nearly 25,631 House Holds (HH) found in the study area. The details of Households are given in Table 3.29. 3.9.4 Population
Village/ town wise population composition as per 2011 census is listed in Table 3.29. The total population of villages covered in 10 km radius is 1,26,230. The male & female population is 65,772 and 60,458 respectively.
The summarized data of population distribution is given in Table 3.29 and represented in Figure 3.21.

3.9.5 Occupational Structure
Work is defined as participation in any economically productive activity with or without compensation, wages or profit. Such participation may be physical and/or mental in nature. Work involves not only actual work but also includes effective supervision and direction of work. It even includes part time help or unpaid work on farm, family enterprise or in any other economic activity. All persons engaged in 'work' as defined above are workers. Persons who are engaged in cultivation or milk production even solely for domestic consumption are also treated as workers. Occupational structure is divided in to 3 categories viz., Main workers, Marginal workers and Non workers. The distribution data for workers and non workers is given in Table 3.30 and Figure 3.22.
Main workers: Those workers who had worked for the major part of the reference period (i.e., 6 months or more) are termed as Main Workers. Marginal workers: Those workers who have not worked for the major part of the reference period (i.e. less than 6 months) are termed as marginal workers. Non workers: All workers, i.e., those who have been engaged in some economic activity during the last one-year, but are not cultivators or agricultural laborers or in Household Industry, are 'Other-Workers (OW)'. The type of workers that come under this category of 'OW' include all government servants, municipal employees, teachers, factory workers, plantation workers, those engaged in trade, commerce, business, transport banking, mining, construction, political or social work, priests, entertainment artists, etc. In effect, all those workers other than cultivators or agricultural laborers or household industry workers are other workers.
3.9.7 Amenities Education, Medical, Water availability, Post & Telegraph, Communication, Banking facilities and Power supply are considered for the study. Village wise list of amenities are given in Table 3.32 (as per 2001 Census).

3.9.8 Conclusion The socio economic studies has been conducted in order to study the present Socio- Economic conditions prevailing around the plant site for the establishment of an interactive environment between the residents of the area with the proponent which would be helpful for the proponent for the assessment of the required developments of the area.
This study was done by looking and maintaining a good understanding of that locality as well as their socio-economic status which can help in the assessment of their Socio-Economic status, costumes, and requirements for the development etc. Based on the study carried out it can be interpreted that proposed project would contribute to improvement in the Quality Of Life (QOL) in the region to some extent in following manner.
Industrial growth will improve economic status of the people either directly or indirectly.
Creation of employment is another positive impact anticipated from this plant. The development of infrastructure (roads, lighting etc.) may not only helpful for
transportation but also to improve aesthetic value of the site. Non-workers comprises of 59% of the total population in the study area. This intense
unemployment fate can be reduced to some extent.
3.10 Traffic Survey Traffic counts are important to calculate the existing and proposed load on the existing road due to upcoming expansion of project.
Project site is to be located near to Sanand-Viramgam Road (State Highway 17). The industry will utilize the stated highway for transportation purpose. Thus, traffic survey has been carried out on above stated highway. Studied route is shown in figure 3.24.
Details regarding the traffic survey are: Traffic counts were collected and recorded in 4 hours intervals. Morning period (pick hours) survey was carried out from 10.00 to 14.00 hrs. Evening period (pick hours) survey was carried out from 16:00 to 20:00 hrs.
Traffic counts observed during the above survey are tabulated below:
