E-4 DESCRIPTION OF ENVIRONMENT

To predict the impact of the proposed activities on the surrounding

environment the current base line environmental status was studied

by collecting the data and carrying out monitoring for the period of

December-10 to February-11. The environmental quality has been

analyzed with respect to ambient air quality, water quality, noise

levels, soil characteristics, flora & fauna and parameters concerning

human interest. Based on the data, the relevant impacts on various

environmental components were also predicted by using appropriate

mathematical models as well as impact assessment techniques. An

appropriate environmental management plan was also delineated to

minimize the adverse impacts.

E-5 Air Environment

The ambient air quality monitoring was carried out at 6 AAQM

locations including project site, with a frequency of twice a week, to

assess the existing sub-regional air quality status for Winter Season

i.e. December-10 to February-11. The Respirable Dust Sampler along

with the analytical methods prescribed by CPCB was used for

carrying out air quality monitoring. At all these sampling locations;

PM10, SO2 and NOx were monitored on 24-hourly basis and grab

sample were collected and analyzed for the HC and VOC to enable

the comparison with ambient air quality standards prescribed by

CPCB.

The data on concentrations of various pollutants were processed for

different statistical parameters like arithmetic mean, standard

deviation, minimum and maximum concentration and various

percentile values.



Respirable Suspended Particulate Matter (PM10)

The arithmetic mean and 98th percentile value of 24-hourly PM10

values at all the locations ranged between and 60-73 μg/m3 and 64-

79 μg/m3 respectively, meeting the CPCB standards of 100 μg/m3.

The 24-hourly concentration values show that the values are well

within the prescribed limit.

Sulphur Dioxide (SO2)

The arithmetic mean and 98th percentile value of 24-hourly SO2 at

all the locations ranged between 15-20 μg/m3 and 17-22 μg/m3

respectively, which are well within the stipulated standards of 80

μg/m3 for residential areas.

Oxides of Nitrogen (NOx)

The arithmetic mean and 98th percentile value of 24-hourly NOx at

all the locations ranged between 14-21 μg/m3 and 17-25 μg/m3

respectively, which are much lower than the standards of 80 μg/m3,

stipulated by CPCB for residential areas.

E-6 Water Environment

Ground water quality

267 mg/l to 408 mg/l), and Iron (ranges from 0.16 mg/l to 0.29

mg/l). Samples were also analyzed for Phenolic compound (less than

0.001 mg/l in all samples).

Conclusions: Ground water samples from villages meets the

permissible limit set by the authority (BIS). Indian standard

specification for drinking water.

E-7 Noise Environment

The Leq values of noise levels during day-time varied between 53.5

to 61.5 dB(A) Highest Leq daytime value was recorded Project Site,

however it is less than the prescribed limit for the residential (75

dB(A)). The Leq values of noise levels during night time varied

between 39.5 to 57.4 dB (A). Highest Leq night time value was

recorded Nr. Project Site which is less than prescribed limit (70 dB

(A)).



E-8 Environmental Impacts and Mitigation Measures

Air Environment

Since M/s. Asahi Songwon Colors Ltd. is the main source of air

pollution is from flue gas stacks and process gas stack. However, the

unit has already provided adequate air pollution control measure.

After proposed expansion there will one boiler and Six thermic fluid heaters

& Five Spin Flash Dryer will be added.

Unit has proposed to install Bag Filter to flue gas stack and two stage

water scrubber to the process gas stack, which will also be adequate

to meet stipulated norms. Adequate stack height will also be

provided for proper dispersion of gaseous emission.

The unit has provided all the precautionary measures to control the

fugitive emission.

Air Quality Modelling and Predictions

It is predicted that the maximum contribution in GLCs, with units

operating at full capacity, is 3.205 μg/m3, 1.472 μg/m3 and 0.485

μg/m3 for SPM, SO2 and NOx respectively 2km away from Project

Site in N direction Where as NH3, HCl , Cl2 were 2.397, 0.291, and

0.125 respectively 1 km away from centre of industry in N direction.

With this marginal contribution due to the expansion of the project,

the levels of SPM, SO2 and NOX will be below residential area limit

prescribed by CPCB.

Water Environment

The additional water requirement for the proposed expansion will be

2105 KL/day, which will be satisfied through own bore well. Source of

water is existing bore well. The main industrial water requirement

will be for the process & washing, utilities, Domestic and gardening.

At present the industrial wastewater generation is 1482 KL/day which

will be reduce up to 1174 KL/day after proposed expansion.

The Company has already installed a full-fledged ETP plant which

comprises of neutralization, equalization, settling, aeration, filtration

through Carbon and sand filters to remove suspended particles. With



minor modifications in existing ETP plant to reduce the water

consumption. After treatment and meeting GPCB norms entire

quantity of treated industrial effluent will be discharged into Mahi

Creek through ECP channel.

The unit proposed ground water recharging sump at low lying area

which will be connected to the storm water drainage system. To

recharging the ground water during the rain, unit will be balanced

ground water.

Hazardous/Solid Waste Management

The main source of hazardous waste generation will be ETP sludge,

which will be sent to TSDF site operated by M/s. Naroda Enviro

Projects Ltd. (NEPL), Naroda-Ahmedabad for final disposal. The other

sources will be generation of discarded drums/barrels/liners/bags

and waste/spent oil respectively from the material handling and

storage and plant & machinery. The discarded

drums/barrels/liners/bags will be decontaminated and reused/sold to

approved scrap vendors whereas spent/waste oil will be reused

within premises as lubricant or sold to MoEF approved scrap vendors.

The unit has also provided isolated area within premises for the

storage and handling of hazardous waste with impervious floor and

roof cover.

Green Belt Development

The unit has already developed green belt on the area of 5475 sq mt.

which will be increased up to 29850 sq. mt. Thus, total area allotted

for the green belt development after proposed expansion will be @

35% of the total industrial area.

E-9 ENVIRONMENT MONITORING

CHAPTER-1

Introduction

1.1 BACKGROUND OF THE COMPANY

M/s. Asahi Songwon Colors Ltd. is the existing unit located at Survey

No. 429 to 432, Village: Dudhwada, Taluka: Padra, Dist.: Vadodara,

State: Gujarat. The unit has been established in the year April, 2005.

Unit has been involved in manufacturing of CPC Blue Crude & Pigment

Beta Blue-A/B with 850 MT/month & 100 MT/month production

capacities.

Now, Unit envisage to increase the production capacity of CPC Blue

from 850 MT/month to 1000 MT/month, Pigment Beta Blue-A/B from

100 MT/month to 500 MT/month with introduce of three new products

– Pigment Alpha Blue: 15/15.1 with 60 MT/month, Pigment Violet-23

with 25 MT/month and Pigment Green-7/36 with 200 MT/month

production capacities.

The promoter Mr. Munjal M. Jaykrishna, Managing Director of the

company, A young and dynamic MBA has very good business

experience in the same field since last 15 years. The company is also

supported by other senior personal including Mr. S. R. Dhoble, a

Chemical Engineer and Vice President have more than 25 year

experience in the chemical industries and overall controlled by the

Executive Directors. The quality of the product has been dramatically

improved and the product has been accepted in the domestic and

international market. Since the unit also believes in the sustainable

development with production and product quality, the unit is equally

concern with the environment preservation and pollution control.

1.2 PURPOSE & NEED OF E.I.A

Environmental Impact Assessment (E.I.A) is a formal document

prepared by independent Environmental consultant, based on the



details/documents provided by the project. The EIA report summarizes

the process and results of the environmental analysis of a project

having the potential for significant and diverse impacts.

Environmental analysis is the process of evaluating the environmental

impact of a project and identifying ways to improve the project

environmentally by preventing, minimizing, mitigating and/ or

compensating for adverse impacts.

M/s. Asahi Songwon Colors Ltd. falls under the category of 5(f) of

schedule of EIA Notification, 2006 “Synthetic Organic Chemical

Industries (Dyes & Dye intermediates; bulk drugs and intermediates

excluding drug formulations; synthetic rubbers; basic organic

chemicals, other synthetic organic chemicals and chemical

intermediates)” and categorized under “A” because unit is located

outside the notified industrial area and appraised at centre level.

Therefore, units require EC for proposed activities.

In view of the above, monitoring work has been carried out for all the

environmental attributers by M/s. San Envirotech Pvt. Ltd. -

Ahmedabad.

The Environmental (Protection) Act-1986 (Environmental Impact

Assessment Notification, 2006) established the requirements for

preparing Environmental Impact Assessment (EIA) in India. The EIAs

subsequently have been prepared, on an individual basis for

new/expansion of project. While the project specific EIAs have been

successful to varying extent in the incorporation of environmental

objectives in the project design, several experiments have been done

to address the issue of cumulative environmental impacts by carrying

out Regional Environmental Impact studies. This has given a basis for

evaluating total environmental impacts of the region and hence helped

in planning at the regional level. Other uses of EIA tool have been in

the Strategic Environmental Assessment (SEA), now mandatory in

many industrialized countries, to evaluate environmental impacts of

policies and programs. Hence, EIA tool has been improvised and used



innovatively for assisting decision-makers in assessment of

environmental impacts and considering alternative mitigation

measures in a variety of situations.

Environmental Impact Assessment (EIA) is required to be carried out

only for certain categories of projects and the criteria for screening

have been provided in the Act. Thus, EIA is essentially made applicable

to industrial and developmental projects, which are more likely to have

significant environmental impacts. Different criteria have been used for

screening. Indian regulation utilizes project category based on the

Scale of Impact, Sensitivity of Impact and Nature of locations as the

primary criteria for deciding on the requirement of EIA for approval.

1.3 STATUTORY REQUIREMENTS

As per the Environment Impact Assessment (EIA) notification issued

by Ministry of Environment and Forests (MoEF), New Delhi dated 14th

September 2006, setting up a new projects or activities, or on the

expansion or modernization of existing projects or activities based on

their potential environmental impacts as indicated in the Schedule to

the notification, being undertaken in any part of India, unless prior

environmental clearance has been accorded.

The proposed expansion of M/s. Asahi Songwon Colors Ltd. is for CPC

crude and CPC Beta Blue with addition of three new products i.e.

Pigment Alpha Blue: 15/15.1, Pigment Violet-23, Pigment Green-7,

which are covered under the said EIA notification and require to carry

out Environmental Impact assessment for its proposed project and

also, require to prepare the report on the same for the perusal of MoEF

for judging the environmental compatibility of the project as discussed

during the presentation of Terms of Reference to Expert committee of

MoEF on dated 22nd October, 2010.



In view of the same, the monitoring/analysis as well EIA-Report

preparation work for the proposed expansion project of M/s. Asahi

Songwon Colors Ltd. has been carried out by M/s. San Envirotech Pvt.

Ltd., Ahmedabad- a reputed Environmental Consultant.

1.4 Regulatory Framework

The MoEF, CPCB and SPCBs together form the regulatory and

administrative core of the sector. Legislation for environmental

protection in India for chemical industry is mainly EIA Notification-

2006, water (Prevention & control of pollution) act-1974, Air

(Prevention & control of pollution) act-1981, Water (Prevention and

Control of Pollution) Cess Act, 1977; Hazardous Wastes (Management

and Handling) Rules, amended time to time etc are major

Act/rules/notification applicable to industry.

1.5 Terms of reference accepted/issued by MoEF on 26/11/10.

As per the discussion during 15th meeting of the Expert Appraisal

Committee (Industry) held on 22nd and 23rd October, 2010 for the

preparation of EIA/EMP, the TOR has been finalized for the proposed

expansion of M/s. Asahi Songwon Colors Ltd. as given hereunder,

1.8 THE STUDY AREA

Project Site

The existing unit of Asahi Songwon Colors Ltd. is located at Survey

No.: 429 to 432, Village: Dudhwada, Taluka: Padra, Dist.: Vadodara,

Gujarat. Since the unit has adequate land for the expansion and site

location is preferable, the proposed project will be carried out in the

same premises.

The location map is shown at Figure 1.1.



Study Area Features

Longitude: 22011’35.47” N

Latitude: 72053’55.47” E


Project Components

The proposed expansion will be in the existing premises located at

Survey No. 429 to 432, Village: Dudhwada, Taluka: Padra, Dist.:

Vadodara, State: Gujarat, having all basic necessary facilities like

infrastructure, communication, medical facilities, power, natural gas,

communication system, well design effluent management facilities

(Water+ Hazardous /solid), raw material availability as well market for

the finished products etc.

The project location is mentioned in the location map attached as

Figure: 1.1.A useful way of identifying many of the potential impacts

of a project is to consider all the aspects of the projects and its

receiving environment and systematically identify the potential for

interactions between them. The first step is to draw up a list of all

project components and activities during each phase of its

implementation. The possible components of proposed project could

lead to environmental impacts are described in this section based on

the understanding of Chemical industry.



Environmental Components

Defining all the possible aspects of the environment is essential for

identification of potential impacts. This may cover features of the

environment (e.g. habitats, settlements, and historic sites); aspects of

environmental quality (e.g. air quality, water quality, noise, physical

conditions, soil stability and hydrology) and uses of the environment

(e.g. agriculture, recreation and fishing). This will be done with

generation of base line data.

1.9 SITE SELECTION CRITERIA

The unit is an existing unit, located at Survey No. 429 to 432, Village:

Dudhwada, Taluka: Padra, Dist.: Vadodara, State: Gujarat. The unit

has been already in existence and the unit is good familiar with the

surrounding environment, therefore, it becomes easy for the unit to

expand the project in the same premises. However, the base of

selection of site was primarily based on the availability of the following

amenities:

Availability of all basic facilities like fuel, water, power,

manpower, raw materials, etc.

The nearest town Baroda is only 30 km away from the project

site which is very well connected with other parts of the country

by road, rail and air.

Good communication and transportation facilities

A treated Effluent disposal facility is also very near to project site

i.e. Effluent Channel Projects.

No R & R will be required

No national park or wildlife Habitats falls within 10 km radial

distance from proposed project site.

1.10 OBJECTIVES OF EIA

EIA is a policy and management tool for both planning and decision

making. EIA assists in identification, prediction and evaluation of the



foreseeable environmental consequences of proposed developmental

and industrial projects.

The objectives of the present EIA Study is to assess the impacts on

various environmental components due to the proposed project and to

recommend appropriate environmental management plant for the unit

to ensure that the adverse impacts if any will be minimized. Moreover

to prepare an Environmental Statement to indicate conclusively if the

overall impacts are positive or negative.

1.11 SCOPE OF EIA

The scope of present Environment Impact Assessment includes

following studies,

Collection and evaluation of project details and related documents

Analysis of the quality of gaseous emission, wastewater analysis,

hazardous waste generation based on the monitoring results for

the last one year

Assessment of pollution potential due to proposed project

Collection and evaluation of present environmental baseline status

within an impact zone of 5-km radial distance from the project

site on environmental parameters/attributes considering the

proposed activities like,

Ambient Air quality

Water quality and surrounding environmental water bodies.

Soil quality

Noise levels

Meteorology and climates.

Land use pattern and socio-economic status

Identification, assessment and evaluation of the beneficial and

adverse impacts on surrounding environment due to proposed

project activities considering the existing baseline status along

with compilation of other information

Identify the sources and impact of hazards, if any



Base on the same suggest and design risk assessment plant and

disaster management plant to prevent any hazard

Preparation of final Environmental Impact Statement & EMP

1.12 METHODOLOGY FOR EIA

Environmental Assessment (EA), another term used in the

environmental studies, refers to an understanding of the present

status of environment and a study of how to manage them.

Keeping in view the nature and size of the proposed project and

industrial area and various guidelines available, it was decided to

cover an area of 5-km radius from the center of proposed plant

site for the purpose of environmental impact assessment study.

The methodology is briefly reported below and has been described

in this section.

Baseline data Collection

The baseline data for the impact zone have been generated for the

following environmental parameters:

Ambient Air Quality

Micrometeorology

Noise Levels

Surface and ground water quality

Soil Quality

Flora and fauna

Land use pattern

Occupational structure and socio-economics

The baseline status of the above environmental parameters has

been worked out based on the rapid monitoring/analysis carried out

during the study period of December-10 to February-11 supplemented

by data collected from various government departments, census

publications etc.

Evaluation of Impact from Project Activities The environmental

Impact resulting from the various project activities, have been



identified, predicted and evaluated based on the study of

manufacturing process and other project related activities as well as

correlating the same with existing base line status.

Preparation of Environmental Management Plan

Environmental Management plan has been prepared covering pollution

prevention measures at source in terms of air and water pollution

control measures, solid waste/hazardous waste management, safety

management, green belt development, environmental surveillance and

environmental management team.

Finally, the detailed assessment of the resultant environmental

impacts have been made based on the impacts identification and

evaluated from the activities over the baseline status of various

environmental components.

2.8 GENERATION OF POLLUTANTS

2.8.1 EXISTING MANUFACTURING ACTIVITIES

A) Process Effluents from Existing Products

The main source of the industrial wastewater generation is process,

washing and utilities. The entire quantity of the industrial wastewater

is segregated in to three parts as per the concentration,

(i) concentrated stream (i.e. ML of acidic treatment of CPC Blue)

(ii) general/weak stream from manufacturing activities of other

product from Manufacturing stream

(iii) Effluent from the utility section i.e. RO reject, DM plant

regeneration, cooling bleed off, boiler blow down etc.

The unit has also provided its own Effluent Treatment Plant

comprising of primary and secondary treatment units to treat the

industrial effluent being generated from the existing production

activities and, then after finally treated industrial effluent is

discharged into ECP channel.

The details of the wastewater generation and Effluent Treatment

plant are depicted in Table-2.4.

B) Gaseous Emissions

The main sources of the air pollution from the existing industrial

activities are flue gas emission and process gas emission. The flue

gas emission is from the common stack attached to steam boiler and

Six nos. of thermic fluid heaters due to combustion of fuel which are

attached to three stack.

Whereas the process gas emission is from the one process gas stack

attached to process vessels (1 to 4), second process stack attached

to Process Vessel (5 to 6) and three process stack attached to spin

flash dryers. Details of pollutant with stack height and APCM

measures are summarized in Table No. 2.8.



C) Fugitive Emission

There are also chances of the fugitive emission due to handling of

process gas emission and hazardous chemicals as well as due to

liberation of the excess solvents from the reactors.

However, to prevent the same the unit takes all the precautionary

measures like adequate scrubbing system to absorb the process gas

and to carry out entire process in the closed reactors, etc. Work

place environment for existing activities are given in Table No.

2.10.

D) Hazardous/Solid waste

The main source of hazardous waste generation is ETP sludge from

the Effluent Treatment facilities. The other sources are discarded

barrels/bags/liners/drums and spent/waste oil from the material

handling and storage and plant & machinery.

The details of the hazardous waste are given Table-2.11 & 2.12.

E) Noise

Noise can be defined as an unwanted sound. It interferes with speech

and hearing and is intense enough to damage hearing or is otherwise

annoying. The definition of noise as unwanted sound implies that it

has an adverse effect on human beings and their environment. Noise

can also disturb natural wildlife and ecological system. Sound is

mechanical energy from a vibrating surface, transmitted by cyclic

series of compression and rarefaction of molecules of the materials

through which it passes.

Sound can be transmitted through gases, liquids and solids. The

number of compressions and rarefactions of the air molecules in the

unit of time is described as its frequency. Frequency is expressed in

hertz (Hz), which is the same as the number of cycles per second.

Noise monitoring for existing plant activities ate given in Table No.

2.13.



2.8.2 PROPOSED EXPANDED CAPACITY

Since the unit proposes to enhance the production capacity of its

existing product with introduction of three new products, there will

be increased in the pollution load due to proposed expansion. The

details are given hereunder,

Liquid Effluents-After proposed capacity

Since most of the industrial activities will be remained same after

proposed expansion, except increased in wastewater generation from

process & utilities. However, after proposed expansion the industrial

wastewater generation will be reduce due to recycling of treated

wastewater.

The unit is also going to continue its current practice of the

wastewater management and entire quantity of the industrial

wastewater will be segregated into three parts depending upon the

concentration. Entire quantity of industrial waste water will be

treated at its own ETP after and finally discharged into ECP channel

which convey the treated effluent into river Mahi Creek.

At present our wastewater discharge is tune around 1482 KL/day

which will be reduced up to 1174 after proposed expansion.

Justification of wastewater reduction after expansion is given in

Figure-2.1(c). (Recycling of water).

The details of the wastewater generation after proposed expansion

and Effluent Treatment plant are depicted in Table-2.4 and Table-

2.5.

To maintain or reduce the wastewater discharge into ECP channel

which convey the treated effluent into river Mahi Creek, unit

proposed to install a RO & Multi effect evaporation systems. The



details of recycling systems are summarized in point no-2.8 and

water balance diagram is work out as per figure-2.1 (b).

B) Gaseous Emissions

In addition to existing sources of air pollutions, there will be one

stack of flue gases (steam boiler and six nos. of thermic fluid

heaters), two process gases and four vents for Spin flash dryers will be

added. Details of pollutant with stack height and APCM measures are

summarized in table no-2.8.

C) Hazardous/ Solid waste

The sources of hazardous waste generation will also be remained

unchanged after proposed expansion however, there will be

increased in the quantity of the hazardous waste generation. Details

of existing source and quantity and addition after proposed

expansion are summarized in Table-2.11.

D) Noise

Power plant will be the major source of noise pollution generation in

addition to existing noise level.

2.8.3 POLLUTION CONTROL STRATEGY

A) Effluent Management

After proposed expansion, industrial effluent treat/handle in our

existing ETP, this is adequate after reduction of industrial

wastewater. The detail of effluent treatment scheme is given

hereunder.

There will be mainly three streams generated during the

manufacturing process (i) concentrated stream (i.e ML of acidic

treatment of CPC Blue) (ii) general/weak stream from manufacturing

activities of other product from Manufacturing stream and (iii)

effluent from the utility section i.e. RO reject, DM, plant

regeneration, cooling bleed off, boiler blow down etc. The effluent



treatment plant is based on segregation system of difference

streams.

ETP Description: The Company has planned to reuse 1837 KL

water per day therefore the amount of Fresh water need will be

around 2105 KL. for processing, steam generation, cooling owers

evaporation, drinking, sanitation, gardening, etc. Details are shown

in Figure No- 2.1 (b) & (c). It is estimated that almost 3100 KL/d

of waste water shall be generated from various processes. Part of the

waste water shall be highly acidic in nature and it will be consumed

in the unit itself and/or sold to end user. This load may further

dropped down if RO rejected is further refined in RO plant to get

good quality of water and further followed with reuse membrane

technology to reduce the load on discharged to ECP Channel. Thus

total load on ETP will be 1174 KL/d. The Company has already

installed a full-fledged ETP plant which comprises of neutralization,

equalization, settling, aeration, filtration through Carbon and sand

filters to remove suspended particles. With minor modifications in

existing ETP plant and taking more efforts to reduce the water

consumption, unit can treat its waste water in existing facility with

some additions of the other equipments.

Copper Removal:

Since the unit is using Cuprous Chloride in the process and hence

Copper is coming in the effluent. Copper is removed by adding

chemical `x’ to the effluent and removed by filtration. The Copper

free effluent is taken to ETP plant for further treatment. The

recovered copper sludge will be sold in the market for recovery of

Copper by manifest mechanism and taking care to sell only

CPCB/GPCB registered recycler which has registration Certificate-

cum-Pass Book for Re-refining/Recycling of Hazardous Wastes.



R.O Regeneration of effluent water & Multi effect evaporator

B) Air Pollution Control

The unit has already provided separate dust collector as air pollution

control measures to the flue gas stack. The unit has also provided

adequate scrubbing system comprising of three stages of water

scrubbers to absorb the process gas generating from the process

reactors for recovery of by-products and controlling the emission

levels as per GPCB norms.

After proposed expansion, as mentioned in above section there will

also be increased in the flue gas stacks due to installation of one new

steam boiler where the unit proposes to install Dust collector-Bag

filter as air pollution control measures.

There will also addition of process gas stack where the unit proposes

to continue its current practice of scrubbing system and will install

the three stage of water scrubbing system, which will be adequate to

meet gaseous emission norms recognized by GPCB.

The unit has already provided adequate stack height of 32.0 m for

flue gas stacks and 15.0 m to process gas emission for the proper

dispersion of the gaseous emission and minimizing the impact of air

pollution at ground level. Now, the unit also proposes to provide

stack height of @ 32.0 m to the proposed steam boiler and 15.0 to

process gas stack, which will also be adequate considering the worse

scenario of Sulphur contents at the rate of 2.4 % in the fuel

proposed to used after proposed expansion.

C) Hazardous/Solid Waste Management

Entire quantity of hazardous waste will be handled and disposed as

per Hazardous Waste (Management, Handling & Trans Boundary

Movement) Rules -2008.

The ETP sludge will be disposed to secured landfill site operated by

M/s. NEPL, Naroda-Ahmedabad. Whereas discarded/ barrels/bags/

drums /liners will be decontaminated and reused/sold to approved

vendors. The spent/waste oil will be sold to CPCB approved recyclers.

D) Ash Disposal

Around 30 % ash of total ash generation will be utilized for bricks

manufacturing and balance ash will be sold off to cement

manufacturer for use in PPC cement, to hollow concrete brick

manufacturer etc., and also will be supplied to the company for land

leveling, conditioning and road construction, etc.



2.8.4 RESOURCE RECOVERY

Liq. Ammonia/Ammonium Carbonate Recovery system

Main source of Ammonical Nitrogen is reaction of Phthalic Anhydride,

Urea, CuCl and acid treatment for purification of products. Second

source is air pollutant-Ammonia scrub by water.

The process emission containing Ammonia and Carbon dioxide

mainly. The Ammonia gas gets absorbed in the water and results in

Liq. Ammonia solution (12–15%). This Ammonia solution is

recovered as By- Product and sold to actual users or converted it to

(NH4)2SO4. Proposed process to generate (NH4)2SO4 and control of

Ammonia and Amonical Nitrogen is summarized below.

Generated acidic water contains (NH4)2SO4 and some part of urea

which is responsible for Ammonical nitrogen in the effluent.

We will isolate acidic effluent stream which contains ammonical

nitrogen, and use to scrub the gases (which contain ammonia and

carbon dioxide). This acidic filtrate will absorb ammonia as

ammonium sulfate. As the pH of this filtrate goes from 2 towards 7

we will go on adding more sulfuric acid for faster reaction.

This will resulted in about 20% ammonium sulfate solution which we

will recover as by product by concentrating through multiple effect

evaporators. There by the effluent stream containing ammonical

nitrogen will be dealt separately and will not go to our effluent

treatment plant.

Generated Ammonium Sulphate will be sold to actual users.



2.9 RESOURCE CONSERVATION

2.9.1 GROUND WATER RECHARGING SYSTEM

The unit proposed ground water recharging sump at low lying area

which will be connected to the storm water drainage system. To

recharging the ground water during the rain, unit will be balanced

ground water.

2.9.2 GREEN BELT DEVELOPMENT

The unit has done extensive plantation in 24375sqm and will be

added some more area for greenbelt development and it will be

around 5475 sqm. After expansion greenbelt will be in 29850 sq. mt.

areas and it will be around 35% of total land area.

2.10 FIRE FIGHTING SYSTEMS

The fire fighting system will be designed by incorporating the

recommendations of the Tariff Advisory Committee of Insurance

Association of India. During the design of such system, codes and

standards of National Fire Protection Association (NFPA), USA will be

taken in to consideration and the same would be applied. Fire

fighting system will consist of hydrant system, water spray system,

foam system, emulsifier system, portable fire extinguishers and fire

alarm system.

The water will be taken from the product water storage tank for fire

water pumps of hydrant network and water spray. Fire water pumps

and fire water storage tanks shall be provided as per regulations.

2.11 RAIN WATER HARVESTING

Rain Water Harvesting is a method of utilizing rain water for

domestic and agricultural use is already widely used throughout the

world. It is a method which has been used since ancient times and is

increasingly being accepted as a practical method of providing

potable water in development projects throughout the world.



Improve the ground water in Industrial area is one of the main

problems which is being faced by developed countries of the world.

In Industrial area the charging of underground water in natural way

like rural areas is not taking place due to large sprawl of Industrial

activities. But it is feasible by inject the water by percolating wells.

To considering the Industrial area and various types of activities may

contaminate the rain water, recharging the rain water by inject the

rain water to underground aquifers is not advisable. Asahi Songwon

Colors Ltd. will reuse the rain water collect from rooftop during the

rainy season.

The average long-term rainfall, out of which 20% of the rainfall is

considered to go to the ground as a natural recharge and remaining

rainfall runoff and this, is available for the artificial recharge after

accounting for soil moisture storage and evaporation.

We proposed two artificial water recharge well in our premises in low

lying are with due considering to avoid any contamination.

CHAPTER-3

Description of the Environment 3.1 Introduction

Any development activities related to industrial sector are expected

to cause impacts on environmental quality in surrounding area of the

respective project locations.

However, the assessment of environmental impacts from proposed

project at a specific location needs a datum on which the evaluation

can be done. It is necessary to collect data about different

environmental attributes that are being affected by the operation of

project activity, which in turn defines an existing environmental

quality to serve as the datum.

Baseline data requirement is also necessary to identify

environmentally significant issues as well as to enumerate the critical

environmental changes that are likely to occur due to proposed

project activity.

Here, in this chapter the baseline status for the surrounding

environment has been determined considering the following

environmental attributes and as per MoEF guidance in approved

Terms of Reference (TORs).

(i) Air Environment

(II) Water Environment

(III) Noise Environment

(IV) Soil Environment

(V) Socio Economic and Land use

(VI) Ecology



3.2 Air Environment

The impact on air environment would depend on identification of

sources of air pollution from various process operations; the nature

of pollutants and their quantities likely to be discharged to the

atmosphere; and the baseline data on air quality.

The baseline data on air quality and micrometeorological conditions

of the area surrounding the project site have been generated through

an appropriately designed network for and monitoring of ambient air

quality (AAQ) within the zone of likely impacts.

3.2.1 Design of Network for Ambient Air Quality Monitoring Stations

The following criteria were taken into account while designing the

ambient air quality-monitoring network:

Topography/Terrain of the study area

Populated areas within the region

Prediction of maximum concentrations and distances of their likely

Occurrence under prevailing meteorological conditions

Representation of regional background

Representation of valid cross sectional distribution in downwind

Direction

Availability of infrastructure facilities like electricity, approach,

safety of equipments etc.

3.2.2 Reconnaissance

Reconnaissance survey was undertaken to establish the baseline

status of air environment in the study region. The prime objective of

the AAQ survey, within 5 km radial study area around the industry at

Survey No. 429 to 432, Village: Dudhwada, Taluka: Padra, Dist:

Vadodara, Gujarat. The terrain of the study area surrounding the

industries is plain. Six Ambient Air Quality Monitoring (AAQM)

stations (One is fixed at Industrial location and five stations were

located in villages in the study area and were change based on the



wind direction. The locations (relative directions and distances) of

these stations with respect to project site are given in Figure 3.6.

The Respirable Particulate Matter (PM10), Sulphur Dioxide (SO2), and

Oxides of Nitrogen (NOx), were identified as significant parameters

for ambient air quality monitoring, particularly because these are

likely to be emitted from the industry and for which ambient air

quality standards are prescribed. Hydrocarbon (HC) and VOC were

sampled and analyze as grab near by industry.

The micrometeorological data on wind speed; wind direction,

temperature and relative humidity were collected through a weather

monitoring station for the study period. The baseline status of air

quality is monitored within the study area i.e. 5 Km radial distance

from project site.

3.2.3 Micrometeorology of the Area

The micrometeorological conditions at the project site will regulate

the transport and diffusion of air pollutants released into the

atmosphere. The principle meteorological variables are horizontal

convective transport (average wind speed and direction), vertical

convective transport (atmospheric stability, mixing height) and

topography of the area. The data on surface meteorological

parameters (wind speed and direction) in the study area were

collected from December-2010 to February-2011 using weather

monitoring station placed at location of Industry. The sensors of this

equipment were kept at about 10 m above ground level with free

exposure to the atmosphere all through the study period in winter

season.

Wind rose

The 24 hour wind rose was prepared using the data on wind direction

and speed collected for December-2010 to February-2011 in the

study area. The same, as depicted in Figure 3.7, shows the



predominant wind directions are N, NNW, NNE, NW & ESE implying

that winds come from these directions for most of the time during

the period. The wind speed class 1-5 kmph occurred for 32.06 % and

6-10 kmph is 18.47 %, 11-15 kmph is 13.88 %, 16-20 is 6.22 % and

more than 20 kmph is observed around 3.19 % of the time during

study period. The calm condition (below 1 kmph) observed is 26.18

% of the time. The local prevailing wind pattern during the study

period is in conformity with the climatologically normal of the region.

The average wind speed recorded is 5.7 kmph during the study

period (December-2010 to February-2011).

Temperature

During the study period the maximum and minimum temperatures

recorded at project site were recorded as 33.8OC and 12.7OC

respectively.

Relative Humidity

At project site during study period, the maximum relative humidity

was recorded as 73.1% and minimum as 15.3%.

For the study area, the year can be broadly divided into following seasons:

Winter Season (November to February)

Summer Season (March to May)

Monsoon Season (June to September)

Transition Month (October)

Winter is mostly cool and pleasant season. Sky is clear with stray

high clouds, winds blowing mainly towards South – West direction.

December and January are the coolest months. April and May are the

hottest months.

The monsoon sets in by about the second week of June. South-west

winds blow from May and last till the end of September. About 95%

of the annual rainfall in the area occurs during the months of June to



September. The normal annual rainfall in this region is 850 mm to

900 mm.

3.2.4 Ambient Air Quality Survey

The ambient air quality monitoring was carried out at 6 AAQM

locations, with a frequency of twice a week continuously for three

months i.e. December-2010 to February-2011, to assess the existing

sub-regional air quality status. The Respirable Dust Sampler along

with the analytical methods prescribed by CPCB was used for

carrying out air quality monitoring. At all these sampling locations;

PM10, SO2, and NOx were monitored on 24-hourly basis and grab

sample were collected and analyzed for the HC and VOC to enable

the comparison with ambient air quality standards prescribed by

CPCB. The data on concentrations of various pollutants were

processed for different statistical parameters like arithmetic mean,

3.4 NOISE ENVIRONMENT

3.4.1 Introduction

Noise can be defined as an unwanted sound. It interferes with speech

and hearing and is intense enough to damage hearing or is otherwise

annoying. The definition of noise as unwanted sound implies that it

has an adverse effect on human beings and their environment. Noise

can also disturb natural wildlife and ecological system.

Sound is mechanical energy from a vibrating surface, transmitted by

cyclic series of compression and rarefaction of molecules of the

materials through which it passes. Sound can be transmitted through



gases, liquids and solids. The number of compressions and

rarefaction’s of the air molecules in the unit of time is described as its

frequency. Frequency is expressed in hertz (Hz), which is the same

as the number of cycles per second.

3.4.2 Methodology

To understand the noise environment in the study area, a survey was

conducted using Sound Level Meter at each of the locations (Figure

3.9).

3.4.3 Ambient Air Quality Standards in Respect of Noise

Ministry of Environment and Forest has notified the ambient

standards in respect of noise in Gazette of India on February 14,

2000. Table 3.11 gives these standards in respect of noise.

3.4.4 Day-Time and Night-Time Noise Levels

Considering the site specificity with respect to settlements, silent

zones (like hospitals, schools) Heavy traffic movements (like state

highways) and the source. Seven locations are selected for Noise

Survey in the day-and night time during the study period. Table

3.10 gives Lday, Lnight noise levels for all locations.

3.4.5 Ambient Noise Levels in Study Area

The Leq values of noise levels during day-time varied between 53.5

to 61.5 dB(A). Highest Leq daytime value was recorded Nr. project

site, However it is less than the prescribed limit for the residential

(75 dB(A)). The Leq values of noise levels during night time varied

between 39.5 to 57.4 dB(A). Highest Leq night time value was

recorded Nr. Project Site which is less than prescribed limit (70 dB

(A)).

3.4.6 Conclusions

The hourly Leq noise levels recorded at various locations in the study

area show considerable fluctuations because of changes in traffic

movement, commercial and industrial activities in the study area.



Though the noise levels found within the prescribed limit both during

day time as well as night time, however the noise level (Leq daytime

as well as Leq night time) found at all locations within limit.

3.5 SOILS

3.5.1 Introduction

Soils may be defined as a thin layer of earth’s crust that serves as a

natural medium for the growth of plants. It is the unconsolidated

mineral matter that has been subjected to and influenced by natural

as well as anthropogenic factors. Soil serves as a reservoir of

nutrients for plants and crops and also provides mechanical

anchorage and favorable tilth.

The study area has primarily Black type of soil. The soils of this type

basically originate from alluvium rocks. According to texture

classification, this belongs to Clay & Clay slit category. This type of

soil has moderate permeability and water retention capacity.

3.5.2 Soil Characteristics

Samples of soils were collected from five locations viz. Project Site,

Village Dudhvada, Village Gametha, Village Karkhadi & Village

Kahanva during the study period and these locations are shown in

Figure 3.10.

The values of important physical and chemical parameters of these

soil samples are given in Table 3.12. From the tabulated values, the

following conclusions can be drawn about the physical and chemical

characteristics of these soil samples.

3.5.3 Findings

Physical Parameters

Particle Size: Particle sizes of the different constituents (clay, silt,

and sand) control the porosity and water holding characteristic of the

soil. Clay (size <0.002 mm) amount in the soil samples ranges from

21% to 29%; Silt (size 0.002 to 0.075 mm) in the soil samples is



30% to 35%; Sand (size 0.075 to 0.475 mm) in the soil samples is

21% to 28% and Gravel (size >4.75 mm) in the soil samples ranges

from 14% to 18%. Analysis shows it is clay loamy soil with moderate

water holding capacity.

Porosity: Porosity is a measure of space in between soil particles

caused by structural conditions and determined under identical

conditions. Porosity of soil samples of the study area ranges from

40.1 to 42.5%.

Water Holding Capacity (WHC): Water holding capacity (WHC) of

soil samples of the study area ranges between 39 to 46% and these

being clay loamy soils are capable of retaining sufficient water during

irrigation for facilitating the plant growth.

Bulk Density: Bulk Density of soils in the study area is found to be

in the range from 1.42 to 1.48 g/cm3. Bulk density is of greater

importance for characterizing the physical behavior of soils. Generally

soils with low bulk density have favorable physical conditions

(porosity and permeability) whereas those with high bulk density

exhibit poor physical conditions.

Chemical Parameters

pH: pH was determined by taking 1:5 ratio of soil and distilled water.

pH of soils in the study area is found to be in the range of 7.4 to 7.9.

The soils of the study area are neutral in nature.

Chloride: Chloride content in soils of the study area is found to be in

the range of 76 to 110 mg/kg.

Calcium: The soluble calcium as CaCO3 in soil samples is found to be

in the range 79 to 109 mg/kg.

Magnesium: Magnesium content in soil samples of the study area

ranges from 43 to 47 mg/kg.

Available Phosphorus: Available Phosphorus content in soil

samples of the study area ranges from 110 to 127 mg/kg.



Available Nitrogen content in soil samples of the study area is

found to be in the range from 149 to 179 mg/mg.

Potassium: Potassium content in soil samples of the study area is

found to be in the range from 50 to 90 mg/kg.

Sodium: Sodium content in soil samples of the study area is found

to be in the range from 72 to 104 mg/kg.

This type of soil is good for agricultural uses.

3.6 SOCIO ECONOMIC AND LAND USE

3.6.1 Land use pattern and infrastructure

The land use pattern indicates the manner in which different parts of

land in an area is being utilized or non - utilized. It is an important

indicator of environmental health; human activity and degree of inter

play between them. Even though the soil quality, water availability

and climate have strong influence on agriculture and vegetation, the

human activity may alter the natural environment to a large extent

to suit human needs. Unnatural land use often triggers rapid

environmental deterioration and disturbs ecological balance.

In census records, major land use classifications are; cultivable area,

cultivable wasteland and area not available for cultivation. Cultivable

land is further classified as: irrigated and unirrigated. Area not

available for cultivation includes lands put to non-agriculture uses as

well as barren and uncultivable lands.

The main land use in urban area is for dwellings, infrastructure and

related activities. These are primarily based on 2001 Census are

presented in Table 3.13.

CHAPTER-4 ANTICIPATED ENVIRONMENTAL IMPACTS &

MITIGATION MEASURES 4.1 GENERAL

Environmental Impact can be defined as any change in

environmental conditions which may be adverse or beneficial

occurred due to action or set of actions under consideration.

Environmental impact can be assessed by identifying the sources of

the impact and predicting the same. The identification of

environmental impacts has been made by co relating the relationship

between project activity and environmental parameters. The project

activities of the proposed project are usually divided into two phases:

Construction Phase and Operation Phase. The activities like mining,

excavation, erosion, building construction, transportation of

construction material, etc. are usually consider in the construction

phase. While in the operation phase the activities like transportation

and storage of raw materials and finished products, manufacturing

process, resource consumption, emergency disaster and green belt

development has been considered.

The next step is prediction of impacts, which is an important

component in environmental impact assessment process. Several

techniques and methodologies are in vogue for predicting the

impacts due to existing and proposed industrial development on

physical, chemical, biological and socio-economic components of

environment. Such predictions delineate contribution in existing

baseline condition for the proposed project. The additional impacts

due to proposed activities are analyzed keeping in mind the baseline

status. This helps assess the assimilative capacity of the environment

and in turn the gravity of the impacts.

The third important component of the environmental assessment is

the evaluation. Based on the identification and prediction of the



nature of impact the environment, the impact can be evaluated

qualitatively and quantitatively.

The environment impact due to proposed activities will be evaluated

considering the following parameters,

• Air Environment

• Water Environment

• Noise Environment

• Land Environment

• Ecology

• Socio-Economic Environment

4.2 AIR ENVIRONMENT

Sources of Impact

There are chances of impact on the air environment due to

installation of new machinery during construction phase and due to

gaseous emission from the flue and process gas stacks during

operational phase.

4.2.1 Prediction of impact

Construction Phase

Since the proposed expansion will be carried out in the existing

premises, no major construction activities will be carried out.

However, there will be chances of dust emission from site cleaning

and construction activity and minor excavation activities. This will be

limited only up to working area. Dust and other emissions are not

likely to spread in wider area, which would affect homes and other

properties. Dust will generate within working areas and measures will

need to taken to protect workers.

However, to mitigate the impact due to Suspended Particulate Matter

(SPM), regular sprinkling of the water will be done along with the

construction activities.

4.2.2 Operational Phase

The impacts on air quality from any project depend on various

factors like design capacity, configuration, process technology, raw



material, fuel to be used, air pollution control measures, operation

and maintenance.

4.2.3 Source of Air Pollution

The main point sources of air pollution due to proposed expansion

project will be of additional flue gas stacks & process gas stacks.

Flue gas stack will be attached to boiler and Thermic fluid heater

where as three process stacks attached to process vessel and third

process stack attached to spin flash dryers.

Flue gas will be mainly due to the combustion of coal/lignite.

However, the unit has provided cyclone separator followed by bag

filter as air pollution control system which will be adequate to meet

the recognized gaseous emission norms. The unit also proposes to

provide proper stack height to all the stacks. Chimney heights have

been chosen such that the generated pollutants disperse effectively

and ensure that the ground level concentrations of pollutants in the

surrounding environment remain well within the permissible limits.

There are also chances of process gas emission- mainly HCl/Cl2 from

the manufacturing of pigment Green-7, where the unit will provide

multistage scrubbing system to reduce emissions of HCl/Cl2.

In Blue Crude plant, NH3 gas will be generated. The unit is already

having scrubbing system in place which is working efficiently and

effectively. The unit proposes to install scrubbing system as per

existing system.

The unit will provide adequate stacks heights of 32 m for the flue gas

stacks (Boiler & Thermic Fluid Heater) and 15-18 m for process gas

stacks, which is adequate for the proper dispersion of the gaseous

emission.

To minimize fugitive emission the unit has adopted the practice of

carrying out entire manufacturing process into closed vessel as well

as provided adequate scrubbing system for efficient absorption of

process gas. Unit also takes special care while solvent recovery.



Special care is also taken while material handling and storage. To

reduce the pollutant emission during transportation, the unit has

adopted the practice of regular check up and maintenance of

vehicular engines for complete combustion of the fuel.

In the present study, the mathematical model that has been used for

predictions on air quality includes steady state Gaussian Plume

Dispersion model designed for multiple point sources.

4.2.4 Air Emissions

The results for gaseous emission for existing flue gas stack as well as

for the process gas stacks are summarized in Table: 4.1.

Gas Stack and process Emission Standard Details for Industry give in

Table: 4.2

The results show that all parameters are well within the stipulated

standards.

4.2.5 Micrometeorology

The hourly wind speed, solar insolation and total cloudiness during

day time and wind speed and total cloudiness during night time were

used to determine the hourly atmospheric stability classes (defined

by Pasquill and Gifford as A to F, A being most unstable and F being

most stable).The hourly stability classes were determined based on

the technique suggested by Turner.

Turner’s system used for determining the stability classes is as

follows:

- For day or night: If total cloud cover (TC) = 10/10 and

ceiling <7000 ft (2134 m), NR=0

- For night-time (defined as period from one hour before

sunset to one hour after sunrise):

a) If TC<4/10, use NR = -2

b) If TC>4/10, use NR = -1

- For daytime: determine isolation class number (IN)

a) If TC<5/10, use NR=IN



b) If TC>5/10, modify IN by the sum of the following

applicable criteria

If ceiling<7000 ft (2134m), modification = -2

If ceiling>7000 ft but <16000 ft (4877 m), modification

= -1

If TC=10/10 and ceiling>7000 ft, modification = -1, and let modified

value of IN=NR, except for day-time NR cannot be <+1.

During the study period stability calculated based on above-

mentioned Turner method gives average stability as A-B class during

Day time and E class during Night time. The mean mixing height

considered for prediction is 100 m as mean minimum and 1000 m as

mean maximum. Average micro meteorological data of December-10

to February-11 is used.

4.2.6 Air Quality Modeling and Predictions using the Gaussian Model

The impact on air quality due to emissions from single source or

group of sources is evaluated by use of mathematical models. When

air pollutants are emitted into the atmosphere, they are immediately

diffused into surrounding atmosphere, transported and diluted due to

winds. The air quality models are designed to simulate these

processes mathematically and to relate emissions of primary

pollutants to the resulting downwind air quality. The inputs include

emissions, meteorology and surrounding topographic details to

predict the impacts of conservative pollutants.

The impacts of air pollutants were predicted using Gaussian air

dispersion model, which is selected on the basis of existence of

multiple point sources within the industrial complex and the plain

terrain at the project site.

The Gaussian air dispersion model has been developed to simulate

the effect of emissions from point sources on air quality. Gaussian

model extensively used for predicting the Ground Level

Concentrations (GLCs) of conservative pollutants from point, area

and volume sources. The impacts of primary air pollutants are



predicted using this air quality model keeping in view the plain

terrain at the project site. The micrometeorological data monitored at

project site during study period have been used in this model.

The Gaussian model provides estimates of pollutant concentrations at

various receptor locations. It is an hour-by-hour steady state

Gaussian model which takes into account the following:

- Terrain adjustments

A Gaussian air dispersion models were used to estimate the ambient

air quality levels at the different monitoring stations due to stack

emissions from Asahi Songwon. Only two stability conditions based

on the meteorology aspects were used to calculate the theoretical

maximum ground level concentration is comparing the actual data

and data generated from mathematical modeling, it highlights that

the stability condition E & A-B were predominant in the region. The

maximum ground level concentration of SPM, SO2 and NOx were

2000 m & HCl, Cl2, NH3 were 1000 m away from the source Using

the existing stack emission data and wind speed directions, a

mathematical model was prepared to establish the ground level

concentration in the region.

4.2.7 Predicted GLCs of proposed Chemicals Plant

It is predicted that the maximum contribution in GLCs, with units

operating at full capacity, is 3.205 μg/m3, 1.472 μg/m3 and 0.485



μg/m3 for SPM, SO2 and NOx respectively 2 km away from Project

Site (Source) in N direction. Whereas NH3, HCl, Cl2 were 2.397,

0.291, and 0.125 respectively 1 km away from centre of industry in

N direction.

With this marginal contribution due to the expansion of the project,

the levels of SPM, SO2 and NOX will be below residential area limit

prescribed by CPCB.

4.3 WATER ENVIRONMENT

Sources of Impacts

The main sources of impact on water environment will be due to

withdrawal of additional fresh water from the ground during

construction and operation phase and treated waste water discharge.

Prediction of Impact

Construction Phase

Since the proposed expansion will be in the existing premises and no

major construction activities will be carried out, there will not be any

adverse impact on the quality of water because very small quantities

of water will be used. No disposal of construction waste outside the

plant and no leaching are anticipated.

Operational Phase

The unit has provided its own bore well to satisfy the water

requirement within premises. At present the total water requirement

is 2188 KL/day for domestic and industrial purpose which will be

reduced up to 2105 KL/day after proposed expansion. This is due to

recycling of treated wastewater.

The main source of industrial wastewater generation will remain

same after proposed expansion, except increase in waste water

generation from process & utilities and it will be control by recycling

of treated water in process.

Impact Assessment

Since fresh water will be required for the proposed expansion, there

will be insignificant impact on the ground water table. However it will



be balanced by recharge ground water during the monsoon season.

For that, Industry proposed to develop recharging sump at low lying

area which will be connected to the storm water drainage system to

recharging the ground water during the rain.

The entire quantity of industrial wastewater will also be treated at its

modified Effluent Treatment Plant and after meeting effluent

discharge norms recognized by GPCB, entire quantity of the treated

effluent will be finally disposed off into sea through ECP project.

To reduce the wastewater discharge into ECP channel which convey

the treated effluent into river Mahi Creek, unit proposed to install a

RO & Multi effect evaporation systems for recycling of treated

effluent and maintain/minimize the discharge to ECP compare to

current consented capacity.

4.4 NOISE LEVEL IMPACT

During construction phase the impact on noise environment will be

due to installation of new mechanical equipments and machineries

while during the operational phase the impact on noise environment

will be due to manufacturing activities, boilers and transportation

activities.

4.4.1 Construction Phase

The noise produced during construction may have significant impact

on the existing ambient noise levels. However, the proposed

expansion of M/s. Asahi Songwon Colors Ltd. is in the existing

premises and there will not be any major construction activities will

be carried out. Minor quantity of noise will be generated due to

installation of new machineries and equipments. The impact will be

very minor and temporary in nature.

4.4.2 Operational Phase

The main sources of noise within the plants are: boiler, Turbine,

transferring pumps and material handling systems. Suitable noise

control system will be provided to ensure that noise at the ventilation



openings does not exceed 90 dB(A) at 1 m distance in conformity

with ISO 3746. The noise level shall, however, exceed the above

limits for a short period during start-up of equipments.

The continuous source of noise during plant operation will be boilers,

turbine, transferring pumps and equipment. The other sources of

noise are the movement of vehicles along the road.

However, proper noise preventive measures have been taken to

minimize the noise pollution like ear plugs, dampers to the boilers,

efficient silencers to the vehicles, etc.

The results of monitoring carried out in the region have been

presented in Chapter-3. The permissible levels in the ambient

environment are presented in Chapter 3. The results are below the

standards prescribed for Industrial environment.

Thus, impact on the environment during the operation phase will be

long term but, insignificant quantity.

4.5 LAND/SOIL ENVIRONMENT

The main source of impact on land and soil environment will be due

to construction activities and hazardous waste disposal.

Construction Phase

Since the proposed project activities will be carried out in the existing

premises. All the existing infrastructure facilities will be utilized with

addition of some new machinery. Therefore, no major construction

activities will be carried out for the proposed project. Further, the

area of the plant is flat. Leveling would not be required. Thus,

topography will also be remained unchanged after proposed

expansion.

Thus, the impact on the land/soil during the construction is for short

terms and insignificant.

Operation Phase

Entire quantity of the hazardous waste will be stored in the isolated

hazardous waste storage area within premises having leachate

collection system and roof cover.



Entire quantity of ETP sludge generated from the Effluent Treatment

Facilities will be sent to TSDF site operated by M/s. Naroda Enviro

Projects Ltd. (NEPL), Ahmedabad for final disposal.

Whereas, discarded barrels/bags/drums/liners will be

decontaminated and reuse/sold to approve vendors and waste/spent

oil will be reused as lubricant within premises or sold to MoEF

approved registered recyclers.

4.6 SOCIO-ECONOMIC ENVIRONMENT

The proposed expansion will be in the existing premises and no

additional land will be required. Therefore, no displacement of person

is envisaged.

The plant is most modern and will require educated and trained

manpower. The surrounding area has got good educational facilities

at Vadodara & Padra. So employment will be satisfied from

surrounding area.

However, some persons with requisite experience is come from

outside also, but most of them may stay at Vadodara.

The operation of the existing plant requires a workforce of 225

persons and after expansion it will be increased up to 350. Thus,

increasing industrial activity will boost up the commercial and

economical status of the locality to some extent.

Thus, overall impacts on socio-economic environment due to the

existence of plant are long term and positive in nature.



4.7 ECOLOGICAL IMPACTS

Impacts of the proposed expansion on the ecological environment

like natural vegetation, crops, fisheries and aquatic life, species

diversity, which is summarized hereunder,

Since the proposed expansion will be in the existing premises, there

will not be any cutting of natural vegetation.

On the contrary, the unit proposes to develop green belt on and

around the premises.

The areas around the premises consist of a dense growth of

vegetation. Various trees, shrubs and herbs are found in and around

it, a list of which is given in Chapter 3. None of the plants are in the

list of Endangered Plant Species.

The high Stomatal Index of Azadirachta indica, makes them

susceptible to SO2. However, the SO2 emissions from the industry

will within limits and proper disperse at the stack height of 32

meters. Hence, no major adverse impact is expected on these plants

with the increased emissions.

The high SPM levels may harm leaves by blocking stomata and thus

interfering with exchange of gases during photosynthesis and

respiration and also cause abrasion of plant surfaces when the wind

blows. But the site is not subjected to high-speed winds and the

plants can be expected to be free from any major impacts of SPM on

plants.

Thus, there will not be any significant impact on ecological

environment due to proposed project activities.

Chapter-5 Environnent Management Plan

5.1 Introduction

Assessment of environmental and social impacts arising due to

implementation of the proposed project activities is at the technical

heart of EIA process. An equally essential element of this process is

to develop measures to eliminate, offset or reduce impacts to

acceptable levels during implementation and operation of projects.

The integration of such measures into project implementation and

operation is supported by clearly defining the environmental

requirements within an Environmental Management Plan (EMP).

From the previous chapter it can be said that the proposed expansion

project of M/s. Asahi Songwon Colors Ltd. has significantly less

pollution potential. For abatement of environmental pollution, the

unit would adopt several measures, which are summarized under in

this chapter.

Since M/s. Asahi Songwon Colors Ltd. is the existing unit and already

have well developed and efficient Environmental Management Plan.

This will be modified/ upgraded as per requirement after the

proposed expansion.

5.2 Objective of Environmental Management Plan

The objective of the Environmental Management Plant is summarized

hereunder,

• To limit/reduce the degree, extent, magnitude or duration of

adverse impacts

• To treat all the pollutants i.e. liquid effluent, air emissions and

hazardous waste with adoption of adequate and efficient

technology

• To comply with all the norms and standards stipulated by

Gujarat Pollution Control Board / Central Pollution Control Board



• To create good working conditions

• To reduce any risk hazards and design the disaster management

plan

• Continuous development and search for innovative technologies

for a cleaner and better environment

5.3 Components of EMP

EMP for the proposed expansion project of Asahi Songwon Colors Ltd.

covers following aspects:

• Description of mitigation measures which are proposed for

proposed operation phase only

• Description of monitoring program

• Institutional arrangements

• Implementation schedule and reporting procedures

All above aspects and objectives are kept in the view and considering

the same EMP is prepared for two major fields,

5.3.1 Environmental Management systems

M/s. Asahi Songwon Colors Ltd. is well aware of environmental

requirements for planning and implementation of the project and set

up a department with trained personnel headed under the qualified

environmental manager. As indicated in the impact and mitigation

chapter of this report, the environmental impact due to the proposed

expansion is very marginal release of pollutants due to proposed

expansion.

5.3.2 Environmental, Health and Safety Management System

Chemical Industries prefer an integrated approach and make

environmental management a part of overall Environment, Health

and Safety (EHS) Management system.

This model EHS system suggests and addresses EMS issues such as:

- Management system expectation

- Management leadership, responsibilities and accountability



- Risk assessment and management

- Compliance and other requirements

- Personnel, training and contractor services

- Documentation and communications

- Facilities design and construction

- Operation, maintenance and management

- Community awareness and emergency response

- EHS performance monitoring and measurement

- Incident investigation reporting and analysis

- EHS management system audit

- Management review and audit

With this type of EHS management approach, proposed expansion of

project would be able to integrate the requirements of ISO-14001

into the overall management system.

5.4 Environmental Management during Construction Phase

Since M/s. Asahi Songwon Colors Ltd. is the existing unit and

proposed expansion will be carried out in the same premises. No

major excavation work will be carried out. Minor activities for the

installation of new additional machineries/equipments will be carried

out. Thus, impact will be temporary and negligible.

Minor construction for installation work shall generate noise and dust

will generate within working areas. Therefore, measures will need to

taken to protect workers.

In order to mitigate the adverse environment impact due to the

construction phase, regular sprinkling of the water will be

recommended along with the construction activities.

5.5 Environmental Management during the Operational Phase

5.5.1 Air Environment

The main Sources of the Air Pollution from the existing industrial

activities are flue gas emission and process gas emission. After

proposed expansion there will one boiler and two thermic fluid



heaters will be added. The flue gas emission is from the common

stack attached to steam boiler and Six nos. of thermic fluid heaters

due to combustion of fuel which are attached to three stack. Whereas

the process gas emission is from the one process gas stack attached

to process vessels (1 to 4), second process stack attached to Process

Vessel (5 to 6) and three process stack attached to spin flash dryers.

The major air pollutants, identified from this industry, will be PM, SO2

and NOx due to flue gas emission & NH3, Cl2 & HCl from process

vent. Generated Ammonium Carbonate and HCl as by products will

be sold to actual users as per the guideline of GPCB.

However, in order to achieve the reduction, it is suggested that

during operational phase regular maintenance and periodic tuning of

the burner system should be done to ensure proper atomization and

subsequent minimization of any unburned combustibles. Besides

reduction in particulate emissions, it would also result in better

operating efficiency of Bag Filter

For this, combustion process may be further improved by adopting

following measures:

I. Optimization of combustion aerodynamics should be done using

a flame retention device.

II. Re-circulation of flue gas may be considered to achieve the

triple goals of low PM emissions, low NOx emissions and high

thermal efficiency.

III. Primary flame zone O2 level should be decreased by decreasing

overall O2 level, controlling (delaying) mixing of fuel and air,

and use of fuel-rich primary flame zone.

Flue gas volume should be checked for amount of air needed for the

complete combustion of the fuel.

The unit during operation phase may also implement energy

conservation measures through installation of heat recovery systems.

This would reduce the fuel consumption and in turn the emissions.



The unit proposes to install Beg Filter to the steam boiler whereas

three stage water scrubber to the process gas stack as air pollution

control system, which will be adequate to meet the stipulated

gaseous emission norms.

The unit will also provide adequate stack monitoring facilities for the

periodic monitoring of the stack to verify the compliance of the

stipulated norms.

5.5.2 Action plan to control ambient air quality:-

Following measures taken by us to control the air quality as per the

NAAQES standards notified by the Ministry on 16th September, 2009.

• Effective implementation of air pollution control measures and

monitoring.

• Ammonia recovery by cooling systems to reduce fugitive

emission.

• Effective scrubbing systems will be installed to control un-

recovered ammonia.

• Proper air pollution control systems like dust collector-bag filter

are installed.

• Material handling systems will be designed to avoid any

spillage.

• Development of greenbelt.

• Improve internal road condition etc.

5.5.3 Green Belt

In order to minimize the air pollution the unit has already developed

green belt on and around its premises. And, now proposes to expand

its green belt area considering the following guidelines,

i) Green cover should be created at all the available open spaces.

ii) To make green belt dense more trees are to be planted at all

patches where plantations already exists.

iii) Strict surveillance is made to increase the survival rate of the

trees.



iv) Plants with higher height, medium and low height should be

planted to ensure thick belt for attenuation of fugitive emission.

This activity demands expert advice and guidance.

5.5.4 Measures to control the fugitive emissions

The fugitive emissions of VOCs emitted from leakage through valves,

fittings, pumps, etc. Excess use of solvent may also results in the

fugitive emission from the process vessels.

Since this is the existing unit it can be seen that there is no major

source of fugitive emission from the process plant. However, the unit

has adopted adequate measures for the minimization/prevention of

the fugitive emission.

The unit has adopted following measures, which will be continued

after proposed expansion.

• Regular maintenance of valves, pumps and other equipment to

prevent leakage and thus minimize the fugitive emissions of

VOCs.

• Entire process is carried out in the closed reactors with proper

maintenance of pressure and temperature.

• Regular periodic monitoring of work area to check the fugitive

emission.

In case modernisation is undertaken by Asahi Songwon Colours Ltd.,

design features as suggested in Table 5.1 for new equipment may

be considered.

5.5.5 Water Environment

Since most of the industrial activities will be remained same after

proposed expansion, except increased in wastewater generation from

process & utilities. However, after proposed expansion the industrial

wastewater generation will be reduce due to recycling of treated

wastewater.

The unit is also going to continue its current practice of the

wastewater management and entire quantity of the industrial



wastewater will be segregated into three parts depending upon the

concentration. Entire quantity of industrial waste water will be

treated at its own ETP after and finally discharged into ECP channel

which convey the treated effluent into river Mahi Creek.

At present our wastewater discharge is tune around 1482 KL/day

which will be reduced up to 1174 after proposed expansion.

Justification of wastewater reduction after expansion is given in

Figure-2.1(c). (Recycling of water).

The details of the wastewater generation after proposed expansion

and Effluent Treatment plant are depicted in Table-2.4 and Table-

2.5.

To maintain or reduce the wastewater discharge into ECP channel

which convey the treated effluent into river Mahi Creek, unit

proposed to install a RO & Multi effect evaporation systems. The

details of recycling systems are summarized in point no-2.8 and

water balance diagram is work out as per figure-2.1 (b).

5.5.6 Artificial water recharge

The average long-term rainfall, out of which 20% of the rainfall is

considered to go to the ground as a natural recharge and remaining

rainfall runoff and this, is available for the artificial recharge after

accounting for soil moisture storage and evaporation.

We proposed two artificial water recharge well in our premises in low

lying are with due considering to avoid any contamination.

5.5.7 Hazardous/Solid Waste Management

Hazardous/Solid Waste management includes following:

- Measures to minimize waste generation

- Operation of waste handling, treatment and disposal facilities

The Waste Management plan includes:

- Waste Inventory



- Classification of waste

- Packaging, Storing and Transporting Wastes to Disposal site

- Data Management and Reporting

- Personnel Training

- Waste Minimization

Since the unit is the existing unit and there will not any major

change in industrial activities after proposed expansion. The unit has

also provided adequate hazardous waste management system, which

will be continued after proposed expansion. The ETP sludge will be

sent to TSDF site operated by M/s. Naroda Enviro Projects Ltd.

(NEPL), Ahmedabad for final disposal.

Whereas discarded bags/liners/drums/barrels will be decontaminated

and reused/sold to approve vendors and spent/waste oil will be

reused as lubricant/sold to MoEF approved registered recyclers.

The unit has also provided isolated area for the storage of hazardous

waste with roof cover and impervious floor.

The unit also maintains the records for the hazardous waste storage

and disposal.

Entire quantity of hazardous is handled as per Hazardous Waste

(Management, Handling & Transboundary Movement) Rules 2008.

5.5.8 Noise Control Technique

At present the main source of noise pollution is boiler/Thermic fluid

heater, vehicular transportation and plant & machinery.

There will be slight increase in noise level due to proposed

manufacturing activities, due to installation of some new additional

mechanical equipment required for the proposed expansion including

power plant.

However, to minimize the noise pollution the unit proposes the

following noise control measures,

Noise suppression measures such as enclosures, buffers and/or

protective measures should be provided (wherever noise level is

more than 90 dB(A).



Employees should be provided with ear protection measures like

earplugs or earmuffs. Earplug should be provided to all workers

where exposure is 85 dB (A) or more.

The transportation contractor shall be informed to avoid unnecessary

speeding of the vehicles inside the premises.

Extensive oiling, lubrication and preventive maintenance will be

carried out for the machineries and equipments to reduce noise

generation.

The selection of any new plant equipment will be made with

specification of low noise levels.

Areas with high noise levels will be identified and segregated where

possible and will include prominently displayed caution boards.

The green belt area will be developed within industrial premises and

around the periphery to prevent the noise pollution in surrounding

area.

Monitoring of noise levels is essential to assess the efficacy of

maintenance schedules undertaken to reduce noise levels and noise

protection measures. A good quality digital sound pressure level

meter is essential for this purpose.

5.5.9 Green Belt Development

Tree plantation is one of the effective remedial measures to control

the air pollution and noise pollution. It also causes aesthetics

improvement of the area as well as sustains and supports the

biosphere.

Plantation around the pollution sources control the air pollution by

filtering the air particulate and interacting with gaseous pollutant

before reaches the ground.

Each plant shows different air pollution tolerance level depending

upon number of factors. In green belt area about 1000 trees per acre

of land as prescribed by Gujarat Pollution Control Board shall

planted. The selection of tree species suitable for plantation at the

industry shall be governed by following factors,



• The trees should be tolerant to air pollutants present in the

area

• The trees should be able to grow and thrive on soil of the area,

be evergreen, inhabitant, having minimum of leaf fall.

• The trees should be tall in peripheral curtain plantation and

with large and spreading canopy in primary and secondary

attenuation zone

• It is also recommended to plant few trees, which are sensitive

to air pollution as air pollution indicator.

The unit has already developed the green belt on 5475 sq mt. area

which will be increased up to 29850 sq. mt. after proposed

expansion.

5.6 RESOURCE CONSERVATION/ WASTE MINIMIZATION

The units shall also implement the concept of waste minimization

circle including:

• By-products recovered and reused.

• Good House Keeping: Proper house keeping practices makes the

system easier and less costly. Some of these are as follows:

• Solid wastes e.g. powders, spills, etc. in process, and packaging

are to be separately collected and disposed off instead of allowing

these to effluent streams. This will reduce load and increase the

efficiency of treatment system.

• Liquid wastes from various sections should be collected and treat

with effluents.

• Rain water harvesting system shall be adopted to reduce the fresh

water requirement.

• Cleaner production technology shall be adopted for the resource

conservation and pollution control.

5.7 HEALTH & SAFETY

M/s. Asahi Songwon Colors Ltd. has followed occupational health

program right from the start of production.



Health hazards associated with occupation are called occupational

hazard. The following check-ups shall be carried out regularly to

avoid occupational hazard,

• Pre-employment medical check-up at the time of employment

• Provision of periodic medical check up for all the employees

• To provide necessary first aid facilities. The first aid training

shall also be given to the employees

• Monitoring of occupational hazards like noise, ventilation,

chemical exposure shall be carried out at frequent intervals.

• The unit will be appoint the medical officer for the regular

medical examination and treatment of the employee

The following precautions shall be taken to avoid foreseeable

accident like spillage, fire and explosion hazards and to minimize the

effect of any such accident and to combat the emergency at site level

in case of emergency.

• Various emergency spots in plant area will be identified and

kept in sharp and alert watch.

• Protective equipments will be regularly checked and will be

kept easily accessible and easily workable during emergency

• Safety installations like available quantity of running water will

be regularly watched.

• Fire bucket and hose reels will be provided to withstand the fire

or explosion conditions

• Various types of fire extinguishers such as (Foam type, water

CO2 type, CO2 type) will be provide inside the factory premises

• Every pressure vessel will be provided with minimum one or

more pressure relief devices. The design of the valve is made

in such a way that the breakage of any part will not obstruct

force discharge of the liquid under pressure. Moreover, relief

valves are tested and a periodic schedule for their testing shall

be maintained. The defective valves will be removed if found

unsafe for the operation



5.7.1 Possibility of occupational health hazard & its control

Following are major health hazards involve in our proposed

activities mainly

Chemical agents: There are possibility to generate gases,

vapours, liquids and aerosols (dusts, fumes, mists). We will take

care to reduce it at optimum minimum level and advices to workers

to use PPE who work in such identify area.

Noise & Heat: Noise is considered as any unwanted sound that

may adversely affect the health and well-being of individuals or

populations. Aspects of noise hazards include total energy of the

sound, frequency distribution, duration of exposure and impulsive

noise. Hearing acuity is generally affected first with a loss or dip at

4000 Hz followed by losses in the frequency range from 2000 to

6000 Hz. Noise might result in acute effects like communication

problems, decreased concentration, sleepiness and as a

consequence interference with job performance. Exposure to high

levels of noise (usually above 85 dB(A)) over a significant period of

time may cause both temporary and chronic hearing loss.

Permanent hearing loss is the most common occupational disease

in compensation claims.

In our case there will be no high noise level issue or heat or

radiation. However we will identify such are like D.G. Sets, utilities

area and advice to workers to not enter without PPE.

Occupational surveillance involves active programmes to anticipate,

observe, measure, evaluate and control exposures to potential

health hazards in the workplace. Depending upon the occupational

environment and problem, two surveillance methods can be

employed: medical and environmental. Medical surveillance is used

to detect the presence or absence of adverse health effects for an

individual from occupational exposure to contaminants, by

performing medical examinations and appropriate tests.



Environmental surveillance is used to document potential exposure

to contaminants for a group of employees, by measuring the

concentration of contaminants in the air, in bulk samples of

materials, and on surfaces.

Medical surveillance is performed because diseases can be caused

or exacerbated by exposure to hazardous substances. We will

appoint part time doctor who are knowledgeable about occupational

diseases, diagnoses and treatment.

5.7.2 Preventive Measures

The methods of protecting the work force from exposure to toxic

agents in the workplace apply to the use of solvents:

• Segregation of processes using solvents;

• Enclosures or special ventilator control of processes;

• Good general ventilation — particularly important if the solvent

is used in a confined space;

• Personal protection — Protective clothing should be worn,

including gloves, where there is a possibility of absorption

through the skin. Suitable respiratory protection is necessary

like Panorama gas mask with cartridge suitable for the

chemicals we will be handling, Breathing Air Apparatus and Air

Hood with instrument air connection.

• Gas detector with emergency alarm systems in confined area.

Emergency preparedness plan

5.7.3 Occupational Health Programme

Some of the philosophies underlining the occupational health

programme are discussed below:

Asahi Songwon Colors Ltd. has employed well qualified and

experienced safety Manager and makes arrangement for part time

doctor for regular checking of health of the employees. Also, plans

to become member of any local hospital for emergency need.

Annual health check for employees will be carried out and record



will be maintained. Regular training to plant personnel in safety fire

fighting and first aid will be provided.

Unit will maintain a healthy work environment. This will be

accomplished through the identification, evaluation and control of

workplace environmental factors which may cause sickness,

impaired health or significant discomfort and inefficiency among

workers. Environmental factors such as noise, physical hazards

toxicity/ chemical hazard and ergonomic hazards will be monitored

on a periodic basis to assist in maintaining a healthy work

environment. Workers exposed to noise and toxic materials will be

evaluated against applicable recognised exposure levels in the

Factories Act. Hearing protection aid will be provided to workers

who work in the high noise areas, during construction of the

proposed facilities and also to those who will continue through the

life of the facility.

5.7.4 Hazard Communication and Chemical Safety

Asahi Songwon Colors Ltd. proposed expansion project will

communicate to its workers information on hazards of the materials

used to its workers.

A hazardous chemical directory is being developed to maintain

information on the hazards associated with each chemical used.

Copies of Material Safety Data Sheets for all hazardous materials at

the existing/proposed facility will be kept at the unit and will be

available for employee review. Specific programs and procedures

for the control of health hazards associated with potentially harmful

materials such as Acids, Alkali and volatile chemicals etc. Will

follow the guiding principles established for Occupational Health.

The hazard communication program will serve as the basis for

selection of personal protective equipment such as gloves, goggles,

face shields, etc. A select group of employees at the proposed



facilities will receive first aid training to provide an immediate

response and medical care for injuries.

5.8 POST-PROJECT ENVIRONMENTAL MONITORING

The post – project environmental monitoring suggested herewith

should be as per the following guideline. The highlights of the

integrated environmental monitoring plan are:

• The stack monitoring facilities like ladder, platform and port –

hole of all the stacks maintained in good condition.

• Regular monitoring of all gaseous emissions from stacks/ vents

and all fugitive emissions in the process areas.

• The performance of air pollution control equipment evaluated

based on these monitoring results.

• Water consumption in the complex recorded daily.

• Analysis of untreated and treated effluent, before discharge

into the final disposal pipeline carried out regularly.

• Performance of effluent treatment plant units evaluated based

on these analysis results.

• As far as possible, noise curbed at its source, with the help of

acoustic hoods and other such noise reducing equipment.

Regular noise level monitoring carried out.

• Green belt properly maintained and new plantation

programmes undertaken frequently.

• Continued environmental awareness programmes carried out

within the employees and also in the surrounding villages.

• Rain water harvesting ponds will be developed within the

industrial premises and encouraged in the surrounding villages

too. All possible back–up and support provided to them.



Ambient Air Quality Monitoring

Schemes for monitoring ambient air quality stack emissions and

fugitive emissions are proposed. The ambient air quality monitoring

systems are recommended for monitoring the ground level

concentrations and fugitive emissions around the plant. Asahi

Sogwon should install three monitoring stations around its battery

limit (at 1200 as per guideline) for monitoring SPM, SO2 and NOx.

The combined data will provide overall characteristic and emission

from the industry. For this, the following equipment is recommended

to be procured or can higher the services from Environmental

consultant by the project proponent for implementing the above

mentioned monitoring schemes:

Respirable Dust sampler

Blower -1.0-1.3 m3/min capacity with adapter for uniform suction

through filter and a properly calibrated manometer assembly for the

determination of flow rate through filter paper

Rota meter- For gaseous sampling, calibrated Rota meter (0-5 LPM)

for maintaining flow rate should be provided

Main housing-The main housing should be rectangular with a stand

of about 1.25 m height.

Besides this, stack emissions monitoring as per GPCB guidelines shall

be carried out.

Noise Environment

Monitoring of noise levels is essential to assess the efficacy of

maintenance schedules undertaken to reduce noise levels and noise

protection measures. A good quality digital sound pressure level

meter is essential for this purpose.

Water Environment

Wastewater is being analyzed at the ETP discharge regularly and

should continue after the expansion also.

Quantitative Risk Assessment 6.1 Introduction

The risk assessment studies have been conducted for identification of

hazards, to calculate damage distances and to spell out risk

mitigation measures.

Asahi Songwon Colors Ltd. is the existing unit located at survey no.

429 to 432, village: Dhudhwada, Taluka: Padra, Dist.: Vadodara,

State: Gujarat. Now, the unit proposes to expand its production

capacity of CPC Blue and Pigment Beta Blue-A/B in existing product

with capacity of 850 MT/month & 100 Mt/Month respectively. Now

Unit envisage to increase the production capacity of CPC Blue from

850 Mt/Month to 1000 MT/month, Pigment Beta Blue from 100

Mt/Month to 500 Mt/Month with introduce of three new product –

Pigment Alpha Blue with 60 MT/month, Pigment Violet–23 with 25

Mt/Month and Pigment Green–7/36 with 200 Mt/Month.

6.1.1 Scope Of Study

The scope of work is to carry out risk analysis for the proposed

expansion of plant covering all the hazardous chemicals to be

handled and stored at the plant after expansion.

6.1.2 Study Objective

The objective of the risk analysis includes the following:

• Identification of hazards

• Selection of credible scenarios

• Consequences Analysis of selected accidents scenarios

• Risk Mitigation Measures

6.1.3 The Study Approach

The risk assessment study broadly comprised of the following steps:

• System Description

• Identification of Hazards



• Selection of Credible Accident Scenarios

• Consequence Analysis

• Risk Mitigation Measures

6.1.4 System Description

This step comprised the compilation of the location, design and

operational information needed for the risk analysis.

6.1.5 Identification of Hazards

Hazards associated with the plant after expansion was identified.

Summary of relevant accident cases was reviewed.

6.1.6 Risk Reduction Measures

Based on hazard identification and consequence analysis, risk

reduction measures were suggested to reduce risk and enhance

safety at the plant.

6.2 PROBABLE HAZARDS & RISK

Hazard identification and risk assessment is carried out through

careful study of plant process. Following this various scenarios by

which an accident can occur are then determined. Concurrent study

of both probability and the consequences of an accident are carried

out and the final risk assessment is made. Since chemical & fuel

posses’ different kind of hazard, both have been separately

associated. The chemicals poses more of Occupational Health Hazard,

while fuel posses more of safety / accidental hazards. Hazard & risk

assessment has been carried out for exposure to harmful dust /

vapors, liquid pool evaporation or boiling and leakage’s in confined

space.

6.3 HAZARDOUS IDENTIFICATION

Hazard is defined as a chemical or physical conditions those have the

potential for causing damage to people, property or the environment.

Hazard identification is the first step in the risk analysis and entails

the process of collecting information on:

• The types and quantities of hazardous substances stored and

handled,



• The location of storage tanks & other facilities,

• Potential hazards associated with the spillage and release of

hazardous chemicals.

6.3.1 Hazardous Substances to be handled at Asahi Songwon

Colors Ltd.

M/s Asahi Songwon Colors Ltd. has been engaged in handling and storage of

various flammable and toxic hazardous materials. Important characteristic of

these hazardous materials are described in details below:

Chlorine gas

Chlorine is a toxic gas (B. P. is -34oC). In liquefied form chlorine is a

clear amber dense liquid. The gas is greenish-yellow, about 2.5 times

as dense as air, and non-flammable. Liquid chlorine causes severe

irritation and blistering of skin. The gas has a pungent suffocating

Odour and is irritant to the nose and throat. It is an extremely

powerful vesicant and respiratory irritant.

Typically, exposure to chlorine concentrations of 3 - 6 ppm results in

a stinging and burning sensation in the eyes. Exposures for 0.5 -1

hour to concentrations of 14-21ppm cause pulmonary oedema,

pneumonitis emphysema and bronchitis. This is usually associated

with marked bronchospasm, muscular soreness and headache. Whilst

there is inevitably a variation in individual susceptibility, typically 4

ppm is the maximum concentration that can be breathed for one

hour without any damage, 40-60 ppm is dangerous for a 30-minute

exposure and a concentration of 1000 ppm is likely to be fatal after a

few breaths. IDLH (immediately Dangerous to Life and Health) value

for chlorine is 10 ppm. Permissible limit in exposure of chlorine in

work environment under Factories Act, 1948 is 1 ppm Time Weighted

Average (TWA) Concentration (8 hours).

used and stored at the plant in small to large quantities as per

requirement. As per Manufacture, storage and Import of Hazardous

Chemicals rules 1989 and amendment subsequently, there will be

only few hazardous chemicals, which have potential for creating risk

to life and property in an unlikely event of leakage or spillage

followed by fire.

The hazardous chemicals are stored at the plant in tank with

adequate dyke. Other chemicals will be stored in cylindrical tanks,

barrels and carboys. Details of storage of hazardous materials are

given in Table - 6.1.

6.4.1 Probable Hazards & Risk

From the preliminary risk assessment study carried out for Asahi

Songwon unit some of the possible hazards have been identified. The

likely accident scenarios considered are given below:

S. No.

Scenario Vulnerability Zone

Remarks

1. Spill of Solvent

Area close to spill area

Isolate the area immediately and ensure no ignition source



/Acids comes nearby. Reclaim the material if possible or cover the spill with sand/mud /foam (to be safely disposed off later)

2. Toxic Liquid Leakage/ Spillage in Confined Space

Confined Area Spillage to be mopped up, decontaminated (if required) and disposed of as per norms. Fresh Air inlet / Ventilation System to be fully opened. Ventilation Exhaust will carry harmful vapors. Personnel to avoid contact with exhaust vapors. Exhaust to be released at safe elevation.

3. Flammable liquid tank in tank farm on fire

Area adjoining to tank periphery/ other tanks in tank farm

Deluge all adjoining tanks till fire stops and heat is dissipated. Transfer/neutralize the spillage (if any).

The above mentioned hazards scenarios can further aggravate into

much more serious incidents if not intercepted in time. The fire in

one tank of tank farm can spread to adjoining tanks and may result

in explosions. The vulnerability zone will be considerably enlarged.

The vapors of toxic fluids/dust if carried away by wind above TLV

concentrations may further enlarge the vulnerability zone. Similarly,

toxic fluid spillage and all wastes leaving the live processing zone if

not decontaminated properly can cause serious health hazard to

plant personnel and persons in nearby area.

6.4.2 Hazards Due to Loss of Containment

In the event of leakage or accidental release of above mentioned

hazardous chemicals, it will create localized effects within the short

distances in side the plant. Adequate safety measures including fire

fighting facilities will be provided to attend any emergency for these

hazardous chemicals. Among the hazardous inventories, Ammonia

gas from process is toxic gas and in unlikely event of release, toxic

vapour cloud may form and move on site or even off site of the plant.



6.4.3 Release of Chlorine

In the event of release of chlorine from 900 kg cylinders, cloud of

toxic gas will be formed and moved towards wind direction. The IDLH

(Immediately Dangerous to Life and Health) concentration value for

10 minutes exposure has been taken as the criteria for the ‘wounded’

category.

6.4.4 Release of Flammable Materials

Solvents and flammable materials will be stored in tanks of various

sizes at the plant to meet the process requirements. Suitable dyke

have been provided for loss of containment. At the time of leakage,

pool will be form in dyke and in an unlikely event of fire thermal

radiation may cause damage to life and property.

6.4.5 Effect & Consequence Analysis

As a part of risk assessment study maximum credible accident

analysis (MCA) is carried out to determine the maximum loss

scenario from this analysis. It is an eventuality which is possible and

will have maximum consequential distances for the particular

hazardous chemicals under evaluation.

The selection of the accident scenarios is based on the engineering

and professional judgment, accident descriptions of the past in

similar type of plants & the expertise in risk analysis studies.

6.4.6 Maximum Credible Accident Scenarios

M/s. Asahi Songwon Colors Limited is dealing with many hazardous

substances. Most of hazardous chemicals are solvents and will not

create major threat to life and property in the event of spillage as

dykes have been provided for full containment. Subsequently their

consequence will be confined within short distances.

Chlorine is major toxic hazardous. Chlorine is stored in 900 kg

cylinders. In an unlikely event of accidental release of chlorine, toxic

cloud will be formed and moved to towards wind directions.

For the selection of maximum credible accident scenarios following

methodology have been adopted:



6.4.7 Methodology for Selection of Accident Scenarios

In this study the following steps were followed for scenario selection

for risk analysis study:

• The hazardous materials handled at Asahi Songwon Colors Limited

6.6 GENERAL SAFETY PRECAUTIONS & OCCUPATIONAL HEALTH:

Safety of plant personnel and equipment’s is of utmost importance

irrespective of plant size. Units should bring its environment, health

and safety policy and follow it. Proper safety procedures are being

followed as far as possible including the use of personal protective

gadgets (hand gloves, dust masks, face shield, goggles, apron etc. as

required) by the workers while charging material manually (if

required) in reaction/purification/washing/storage vessel, operating

filter; flushing the equipment or pipe line; and drawing samples for

analysis to prevent hazardous exposure to worker and to avoid spill

of inflammable chemicals. Avoid contact with the raw materials

(touch, inhale or oral route) with the use of Personal protective

equipment. Prevention is better than cure. Safety of plant personnel

and equipment’s is of utmost importance irrespective of plant size.

Units should bring its environment, health and safety policy and

follow it. Proper safety procedures are being followed as far as

possible including the use of personal protective gadgets (hand

gloves, dust masks, face shield, goggles, apron etc. as required) by

the workers while charging material manually (if required) in

reaction/purification/washing/storage vessel, operating filter;

flushing the equipment or pipe line; and drawing samples for analysis

to prevent hazardous exposure to worker and to avoid spill of

inflammable chemicals. Avoid contact with the raw materials (touch,

inhale or oral route) with the use of Personal protective equipment.

Prevention is better than cure. A schedule has been drawn up for

regular preventive maintenance of each unit and the same needs to

be faithfully followed as far as possible. All the valves, which are

prone to open and spill inflammable / toxic material due to accident

impact, must be placed with suitable guard. The unit's management

should ensure that all rotating machines and moving parts are

provided with appropriate guards and the guards are put back in the

position after check up and maintenance.



All the control systems are being periodically checked for their

reliability and accuracy.

Ventilation has been provided in process area where chances of build

up of concentration of hazardous chemicals are high to prevent

fire/toxic hazard.

Electrical grounding of all equipment is ensured.

Units' management has identified all hazardous chemicals in use in

the plant and prepared Safety Data Sheets for most of them. Safety

Data Sheets are quite comprehensive and provide important

data/information on physical and chemical properties, fire and

explosive hazards, toxic limits, emergency and first aid measures etc.

6.6.1 Occupational Health and First aid Measures

Units are using a number of chemicals, which if handled in safe ways

with all precautions (as detailed in respective MSDS) will not cause

harm to employees. However in rare case of exposures, immediate

action is to be taken to save life and reduce the extent of damage.

Unit has first aid facilities and calling base ambulance facilities as and

when required. Industry has appointed part time doctor for

periodically health check.

Instructions for immediate actions to exposures to some of the

chemicals will be given to employees.

6.6.2 Risk Reduction Measures

For risk mitigation / reduction, attempts should be made to either

reduce inventories that could get released in the event of loss of

containment or failure likelihood’s or both as feasible. Risk analysis

identifies the major risk contributors, which enables prioritization of

the plant that deserve special attention in terms of inspection and

maintenance in particular and over all safety management as a

whole.

For the risk reduction at Asahi, the following salient suggestions and

recommendations are made:



• On site and off site emergency response plan should be prepared

and circulated to concern persons.

• Personnel at the proposed plant and public in surrounding area

should be made aware about the hazardous substance stored at

the plant and risk associated with them.

should be provided at strategic locations in the plant and

indication of detectors/sensors should be provided in main control

room.

• A system of checking testing/sealing of relief valves during major

plant overhauls should be instituted for plant equipment,

wherever it is applicable.

• Predictive and preventive maintenance schedule should be

prepared for equipment, piping, etc. and thickness survey should

be done periodically as per standard practices.

• A written procedure (Management of Change) must be developed

to manage changes to process chemicals, technology, equipment

and procedures that affect a covered process.

• Safe work practices should be developed to provide for the control

of hazards during operation and maintenance such as: i. lockout



/tag out ii. Confined space entry iii. Opening process equipment or

piping iv. Control over entrance into a facility by maintenance,

contractor, laboratory, or other support personnel.

• Personnel engaged in handling of hazardous chemicals should be

trained to respond in an unlikely event of emergencies.

• The plant should check and ensure that all instruments provided in

the plant are in good condition and documented.

• Close loop type fire hydrant system pressurised at 7 kg/cm2 with

jockey pumps should be provided in flammable chemical storage.

• Safety measures in the form of DO and Don’t Do should be

displayed at strategic locations especially in local language and

English.

• Regular mock drills should be carried out once in every 3 months

and shortcomings should be recorded and rectified. Records

should be maintained for the response of Mock Drills and

corrective actions should listed and taken accordingly.

6.6.3 Safe Guards for Storage and Handling of Hazardous

Chemicals

Personal Protective Equipment

Personal protective equipment is devices that are fitted and issued to

each worker personally for his or her exclusive use. They are

intended for temporary use and emergency response action only. If a

worker must enter a contaminated area, he must wear adequate

protective equipment suitable for chlorine service. Employees should

be taught when and how to use respiratory apparatus provided, and

how to recognize defects in the equipment. Full dress escape drills

should be conducted at least once a year. If such safety equipment is

not available, entry into the contaminated area should not be

attempted.

• Keep personal protective equipment where it can be accessed

quickly, outside the chlorine storage area and away from areas of

likely contamination.



• Employees who work near chlorine must be issued a properly

fitting cartridge type or canister type escape respirator.

• Facial hair should not be permitted for those who are issued

escape-type or self-contained respirators because it prevents a

proper seal.

• Workers should always carry escape type respirators while

working around chlorine.

• Each employee should maintain his/her personal protective

equipment in clean, working condition at all times.

• All equipment should be used and maintained in accordance with

the manufacturer’s instructions.

CHAPTER-7

Onsite Disaster Management Plan

7.1 INTRODUCTION

An emergency is said to have arisen when operators in the plant are

not able to cope with a potential hazardous situation i.e. loss of

control of an incident causes the plant to go beyond its normal

operating conditions, thus creating danger. When such an emergency

evolves, chain of events which affect the normal working within the

factory area and/or which, may cause injuries, loss of life, substantial

damage to property and environment both inside and around the

factory take place and a DISASTER is said to have occurred.

M/s. Asahi Songwon Colors Ltd. is the existing unit, involved in

manufacturing of CPC blue crude & Pigment Beta Blue. Now, unit

proposed to expand its production capacity of existing products with

introduce of three new products i.e. Pigment Alpha Blue: 15/15.1,

Pigment Violet – 23 and Pigment Green – 7/36.

As described in previous chapter-6, the risk assessment studies have

been conducted for identification of hazards, to calculate damage

distances and to spell out risk mitigation measures.

Despite of our best efforts in the way of managing an emergency

situation lies in the prevention of the any risk hazards from the

manufacturing process or material handling, things can go wrong.

Therefore, it is essential to plan and develop the support system,

which will be required in case an emergency arises.

7.2 PROBABLE HAZARDS & RISK

From the preliminary risk assessment study presented in Chapter 6

of this report, some of the possible hazards have been identified.



7.3 OBJECTIVES OF THE PLAN

Following are the Objectives of the disaster management plan:

• To define and assess emergencies, including risk and environment

impact assessment.

• To reduce possibilities of accident

• To safeguard employees, visitors and other people in the vicinity.

• To minimize damage to property and / or the environment.

• To inform employees, general public and the authorities about the

hazards/risk assessed, safeguard provided, residual risk if any and

the role to be played by them in the event of emergency.

• To be ready for the mutual aid if need rises to help the

neighboring unit. Normal jurisdiction of an On-site Emergency

Plan is the own premises only, but looking to the time factor in the

arriving the external help of off-site plan agency, the jurisdiction

must be extended outside to the extent possible incase of

emergency occurring outside.

• To inform authorities and mutual aid centers to come for help.

• To affect rescue and treatment of casualties to count injured.

• To identify and list any dead.

• To inform and help relatives.

• To secure the safe rehabilitation of affected area and to restore

normalcy.

• To provide authoritative information to the news media.

• To preserve records, equipment, etc., and to organize

investigation into the cause of the emergency and preventive

measure to stop its recurrence.

• To insure safety of the works before personal re-enter and resume

work.

• To work out a plan with all provisions to handle emergencies and

to provide for emergency preparedness and the periodical

rehearsal of the plan.



The structure of the plan may vary depending on number of

employees, materials and processes, availability of resources,

location of site, size and complexity of work.

The plan should not be complicated. Instructions should not overlap

or create any confusion. Responsibilities should be clearly assigned

and should be workable smoothly. For clear understanding and quick

action, the action (Role) by each individual (his emergency duty)

should be prepared in a booklet or card size and given to him.

7.4 IDENTIFICATION OF MAJOR HAZARDS

The major hazardous field where disaster management plant is

required are as under,

• Bursting of high-pressure steam pipe, vessels, etc. due to

abnormal pressure rise

• Fire hazard due to ignition of fuel

• Inhalation of any hazardous chemical

7.5 SCOPE OF PLAN

• The plan will set into action immediately after a fire or other

hazard occurs in and around the plant

• Fuel storage facility is situated away from the manufacturing plant

and fulfilling all rules and regulations

• All the electrical fittings are of explosion proof fitting

• All necessary fire-fighting arrangements have been provided near

the storage area

7.6 THE AVAILIBILITY, ORGANIZATION AND UTILIZATION OF

RESOURCES AND FACILITIES FOR EMERGENCIES

In order to maintain an emergency response capability, certain

facilities must be kept in a state of readiness and sufficient supplies

and equipment must be available. In some cases, it may be

impossible to maintain all of the equipment necessary for all possible

emergencies. In these cases, agreements have to be made with



neighboring facilities to provide additional support as and when

necessary.

Where the local police or private agencies may be called upon, such

as volunteer fire companies and ambulance associations, agreements

have to be developed ahead of time. Emergency hardware can be

classified according to its use during the response operations.

Typical examples are:

• Emergency operation centers

• Communication equipment

• Alarm system

• Personal protection equipment

• Fire fighting facilities, equipment and supplies

• Spill and vapor release control equipment and supplies

• Medical facilities, equipment and supplies

• Monitoring systems

• A media Center

• Transportation system

• Security and access control equipment

Some of these resources will also be available in the local

municipalities. It is the responsibility of the plant management to

ensure that the appropriate equipments and materials are available

to respond to their very hazard-specific emergencies at the facilities,

independently from external resources. These resources can be

extremely valuable, but should be used mainly in support of the main

response actions that the facility personnel will have to implement in

case of a serious emergency.

In any case, the availability of resources within the community must

be determined beforehand, so that these resources can be mobilized,

if the time comes to do so.
