E-8 ENVIRONMENTAL IMPACTS AND MITIGATION MEASURES
Air Environment
The main point sources will be flue gas emission from the stacks
attached to boilers, thermic fluid heater and hot air generators due to
combustion of bio fuel (Briquettes) and process gas emissions i.e.
ammonia gas, from the two reactor vessels.
Since Bio fuel will be used as fuel, comparatively less pollution will be
generated. However, the unit proposes to install dust collector to each
of the stacks.
SAN Envirotech Pvt. Ltd, Ahmedabad
REIA of Narayan Organics Pvt. Ltd., Unit-II E-6
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. The unit proposes to provide adequate stack height
of 30.0 m and 15.0 m respectively to flue gas stacks and process gas
stacks.
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.
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
prediction on air quality includes steady state Gaussian Plume
Dispersion model designed for multiple point sources.
Air Quality Modelling and Predictions
It is predicted that the maximum contribution in GLCs, with units
operating at full capacity, is 3.469 μg/m3, 0.817 μg/m3 and 0.661
μg/m3 for SPM, SO2 and NOx respectively and for NH3 maximum GLC
will be 1.351 μg/m3. The point of maximum concentration by unit
would be 2.0 km from centre of industry in E direction for SPM, SO2
and NOx and 1.0 km from centre of industry in E direction for NH3.
With this marginal contribution due to the proposal of the project, the
levels of PM, SO2 and NOX well within the permissible limits as
prescribed by CPCB.
Water Environment
The main source of the water will be ground water. The unit will install
its own bore wells within premises to satisfy its fresh water demand.
Necessary permission will also be obtained from CGWA.
SAN Envirotech Pvt. Ltd, Ahmedabad
REIA of Narayan Organics Pvt. Ltd., Unit-II E-7
The fresh water requirement for the proposed project will be
683.0 KLD, out of which 671.0 KLD will be utilized for industrial
purpose and remaining 12.0 KLD will be utilized for domestic and
gardening purpose.
The waste water generation will be from the process, washing, boiler
blow down, cooling bleed off, RO reject, etc. Entire quantity of
industrial effluent will be separated into three streams. Concentrated
acidic stream will be segregated and neutralized. Then neutralized
effluent will be collected and mixed with general stream and treated at
its own effluent treatment plant comprising of primary and secondary
treatment facilities followed by tertiary treatment units. Whereas the
third utility stream will be collected into treated effluent collection
sump. After confirmation of stipulated effluent discharged norms,
entire quantity of treated effluent will be discharged into Mahi River
through ECP channel.
Solid Waste Management
The entire quantity of hazardous waste will be handled and disposed
as per Hazardous Waste (Management, Handling and Trans boundary
Movement) Rules’2008. ETP sludge will be sold to cement
manufacturers or sent to approved TSDF site whereas discarded
barrels/bags will be properly cleaned & sold to approved end users and
if excess then reuse within premises. Spent/waste oil will also be sold
to CPCB approved recyclers.
The unit will provide isolated area for the storage of hazardous waste
having leachate collection system, impervious floor and roof cover.
Thus, hazardous waste management system provided by the unit will
be adequate.
Green Belt Development
The unit will do plantation in around 11220 sq. m, which will be around
33% of total land area.

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.

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.
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 one season i.e. Decemeber-10 to February-10,
supplemented by data collected from various government departments,
census publications etc.

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.
2.9.2 POLLUTION CONTROL STRATEGY
The unit proposes to provide adequate and efficient Environmental
Management System. The details are given hereunder,
A) Effluent Management
San Envirotech Pvt. Ltd-Ahmedabad
REIA of Narayan Organics Pvt. Ltd., Unit-II
2-12
The unit proposes to provide its own Effluent Treatment Plant within
premises comprising of primary and secondary treatment facilities to
treat industrial effluent likely to be generated after proposed project.
After meeting effluent discharge norms, entire quantity of industrial
effluent will be discharged into ECP channel of Mahi River.
The stream wise brief description of effluent treatment scheme is given
hereunder,
(I) Concentrated Streams
The concentrated stream i.e. highly acidic ML will be segregated and
collected in acid proof brick lined tanks. Higher acidic effluent will be
reuse in the production of CPC crude and for production of by products
(Ammonium Sulphate). Dilute Acidic effluent will be taken into ETP
collection tank. The pH of acidic effluent will be raised to 9.5 using
hydrated lime, so as to precipitate out the copper salts in the form of
copper hydroxide and it will be pumped to plate and frame type of filter
press. The filtered from plate and frame filter press will be taken to the
filtered collection tank from there it will be conveyed to collection cum
equalization tank of general stream for further treatment. The sludge will
be removed from filter press at periodically and will store separately and
then will be either sent to the TSDF site or to cement manufacturing
units.
(II) General Stream:
The general stream consisting of wastewater other than concentrated ML
from process will be collected in equalization cum collection tank fitted
with stirring facilities. From where effluent will be pumped to flash mixer
after correcting to desired level of pH. In the flash mixer required
chemical will be added and then it will be taken to flocculation chamber
for effective formation of flocs. The overflow of flocculation will be taken
to primary settling tank for settlement of the flocs. The settled sludge
from the PST will be removed and sent to filter press for dewatering.
San Envirotech Pvt. Ltd-Ahmedabad
REIA of Narayan Organics Pvt. Ltd., Unit-II
2-13
The clear supernatant from PST will be sent to the aeration tank having
floating diffusion aeration system for secondary treatment.
The over flow of aeration tank with biomass will be go to the Secondary
Setting Tank where settled biomass is partly recycled back to the
aeration tank and partly wasted out in sludge sump. The over flow of the
Secondary Settling Tank is collected to final Treated Water Sump and
subjected to the tertiary treatment by passing through sand filter and
carbon filter prior to the final disposal.
After confirmation of effluent discharged norms, entire quantity of
treated effluent will be discharged in to ECP channel to Mahi River.
The details of Effluent Treatment Units are given in Table: 2.5. The
schematic flow diagram of Effluent Treatment Plant is given in Figure:
2.3.
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 and convert it to ammonium sulfate. As the
pH of this filtrate goes from 2 pH towards 7 pH, we will add 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 actuak users.

B) Air Pollution Control
The unit proposes to provide separate dust collector as air pollution
control measures to each of the flue gas stacks. Whereas the unit
proposes to provide adequate scrubbing system for process gases
pollutant comprising of two stages of water or Acidic 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.
Adequate stack height of 30.0 m to each of the flue gas stacks and 15.0
m to each of process gas will be provided for proper dispersion of the
gaseous emission and minimizing the impact of air pollution at ground
level.
C) Hazardous/Solid Waste Management
The entire quantity of hazardous waste will be handled and disposed as
per Hazardous Waste (Management, Handling and Trans boundary)
Rules’2008.
The unit proposes to provide adequate area for the storage of hazardous
waste having leachate collection system, roof cover and impervious floor.
Part of the ETP sludge will be sold to cement industries and remaining
will be disposed to secured landfill site approved by GPCB. 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.
2.9.3 RESOURCE RECOVERY
Ammonium carbonate solution12-15% Conc./Ammonium
Sulphate Recovery system
Main source of Ammonia is air emission from process. This will be
scrubbed by acidic effluent generated from process.
We will isolate acidic effluent stream which contains ammonical nitrogen
and use to scrub the gases (which contain ammonia and carbon dioxide).
San Envirotech Pvt. Ltd-Ahmedabad
REIA of Narayan Organics Pvt. Ltd., Unit-II
2-15
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.
Generated Ammonium Sulphate will be sold to actual users.

Baseline Environmental Status 3.1 PRELUDE
Any developmental activities related to industrial sector are expected to
cause impacts on environmental quality in surrounding area of the
respective project locations. However, the intensity of environmental
impacts from a specific project depends on several factors such as type of
process (physical, chemical, fuel combustion etc.) involved in the project,
processing capacity (scale/size of the project), type and extent of pollution
control measures, project location, surrounding geomorphology,
demography, quality of life, etc. To assess environmental impacts from
proposed project at a specific location, it is essential to monitor the
environmental quality prevailing in the surrounding area prior to
implementation of the proposed project. The environmental status within
the impact zone could be used for identification of significant
environmental issues to be addressed in the impact assessment study.
The impacts from an existing industrial project on its surrounding
environment are mainly regulated by the nature of pollutants, their
quantities discharged to the environment, existing environmental quality,
assimilative capacity of the surrounding environment and topography and
terrain of the project site (its location) as well as the surrounding area.
In order to identify and establish the extent of likely impacts, it is essential
to gather information on existing environmental quality with regard to
various components of the environment.
3.2 AIR ENVIRONMENT
The impact on air environment would depend and has been identified on
the basis of identification of sources of air pollution from various process
operations; the nature of pollutants and their quantities likely to be
San Envirotech Pvt. Ltd - Ahmedabad
REIA of Narayan Organics Pvt. Ltd.-Unit-II 3-2
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
(NAAQ) 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
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 NAAQ
survey, within 05-km radial study area around the plant, was to establish
the existing ambient air quality levels. Six Ambient Air Quality Monitoring
(AAQM) stations were selected based on the criteria used for designing the
network. The locations (relative directions and distances) of these stations
with respect to project site are given in Figure 3.5 and details of these
stations are described in Table 3.1.
The Particulate Matter (PM10), Particulate Matter (PM2.5), Sulphur Dioxide
(SO2) and Oxides of Nitrogen (NOx), HC and VOCs were identified as
significant parameters for ambient air quality monitoring, particularly
because these are likely to be emitted from the industries and for which
ambient air quality standards are prescribed.
San Envirotech Pvt. Ltd - Ahmedabad
REIA of Narayan Organics Pvt. Ltd.-Unit-II 3-3
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. 05-Km radial distance from project site as per the
latest regulatory guidelines.
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 (hourly average wind
speed and direction) in the study area were collected during 1st week of
December-2010 to February-2011 using automatic weather monitoring
station placed at Industry site. 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.
Windrose
The 24 hourly wind rose was prepared using the data on wind direction
and speed collected for winter season in the study area. The same, as
depicted in Figure 3.6, shows the predominant wind directions are NNW,
NW, N, NNE, and 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 32.0 %, 6-10 kmph about 18.47 %, 11-15 kmph 13.89 %
and above 15 kmph and below 35 kmph occurred for 9.46 % of the study
duration and of the time. The calm condition (below 1 kmph) observed is
26.18 % of the time. The wind data generated at site were also compared
with the climatological data obtained from the closest Indian
Meteorological Department (IMD) station at Ahmedabad. The local
prevailing wind pattern during the study period is in conformity with the
San Envirotech Pvt. Ltd - Ahmedabad
REIA of Narayan Organics Pvt. Ltd.-Unit-II 3-4
climatological normal of the region. The average wind speed recorded is
6.1 kmph during the study period.
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
During study period at project site during study period, the maximum
relative humidity was recorded as 73.1% and minimum as 15.3%.
Rainfall
No rainfall during the study period at project site.
3.2.4 Ambient Air Quality Survey
The ambient air quality monitoring was carried out at Six AAQM locations,
with a frequency of twice a week continuously for three months, to assess
the existing sub-regional air quality status in winter season. The
Respirable Dust Sampler and Fine particulate sampler along with the
analytical methods prescribed by CPCB were used for carrying out air
quality monitoring. At all these sampling locations; PM10, PM2.5, SO2 and
NOx were monitored on 24-hourly basis to enable the comparison with
ambient air quality standards prescribed by the Central Pollution Control
Board.
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.
3.2.5 Baseline Status
The existing baseline levels with respect to PM10, PM2.5, SO2, NOx, HC and
VOCs are presented in Tables 3.2 to 3.7 along with statistical analysis;
represent the cross sectional distribution of baseline air quality status of
the study region.
San Envirotech Pvt. Ltd - Ahmedabad
REIA of Narayan Organics Pvt. Ltd.-Unit-II 3-5
Respirable Suspended Particulate Matter (PM10)
An average and 98th percentile value of 24-hourly PM10 values at all the
locations ranged between 44-59 μg/m3 and 62-78 μg/m3 whereas the
stipulated standards of CPCB for industrial areas 100 μg/m3.
Particulate Matter (PM2.5)
An average and 98th percentile value of 24-hourly concentrations of SPM
value at all the locations ranged between 25-34 μg/m3 and 36-47 μg/m3
respectively. The stipulated standard of PM2.5 for industrial area is 60
μg/m3 for residential area.
Sulphur Dioxide (SO2)
An average and 98th percentile value of 24-hourly SO2 value of arithmetic
mean at all the locations ranged between 10-15 μg/m3 and 14-22 μg/m3
respectively, which are well within the stipulated standards 80 μg/m3 for
industrial areas.
Oxides of Nitrogen (NOx)
An average and 98th percentile value of 24 hourly NOx value of arithmetic
mean at all the locations ranged between 09-17 μg/m3 and 14-23 μg/m3
respectively, which are much lower than the standards stipulated by CPCB
for industrial areas 80 μg/m3.
3.2.6 Identification of Impacts
The identification of impacts with regard to air environment involves a
careful consideration of all the major process operations, burning of fuel
required for generating the energy in terms of steam, hot air generator
and other activities that may lead to generation and discharge of air
pollutants to the atmosphere. The main source of air pollution will be flue
gas emission and process gas emission. The flue gas emission will from
the boilers, Thermic fluid heaters and hot air generators where biofuel
(Briquettes) will be used. Ammonia will be liberated as process gas.
However, adequate air pollution control measures will be provided to meet
gaseous emission norms recognized by GPCB.

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 Eight locations including
the plant site is shown in Figure 3.8.
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 3.12
depicts these standards in respect of noise.
San Envirotech Pvt. Ltd - Ahmedabad
REIA of Narayan Organics Pvt. Ltd.-Unit-II 3-8
3.4.4 Day-Time and Night-Time Noise Levels
The Leq values of noise levels during daytime (Ld) varied between 53.1 to
61.9 dB (A). Highest Ld value was recorded near Bus stop Vavadi (61.9 dB
(A)) while the Leq values of noise levels during night time (Ln) varied
between40.0 to 53.2 dB (A). Highest Ln value was recorded at Bus stop
Vavadi (53.2 dB (A)).
3.4.5 Conclusions
The hourly Leq noise levels recorded at various locations in the study area
show considerable fluctuations because of changes in traffic movement,

3.5 SOIL ENVIRONMENT
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 genetic and
environmental factors. Soils serve as a reservoir of nutrients for plants
and crops and also provide mechanical anchorage and favorable tilth.
The study area has primarily Grey Brown Aridisols type of soil. The soils of
this type basically originate from alluvium rocks. According to texture
classification, this belongs to Clay Loam category. This type of soil has
moderate permeability and water retention capacity. This soil has
moderate erosion potential.
The study area has following physical and chemical characteristics.

3.5.2 Soil Characteristics
Samples of soils were done at 6 locations (Nr. Industry, Piludrara, Vedach,
Gajera, Dabha, Abhol). During the study period and these locations are
shown in Figure 3.9.
The values of important physical and chemical parameters of these soil
samples are depicted in Table 3.13. From the tabulated values, the
following conclusions can be made about the physical and chemical
characteristics of these soil samples.
3.5.3 Corollaries
Physical Parameters
Particle Size: A Particle size of the different constituents (clay, silt, sand
and gravel) controls the porosity and water holding characteristic of the
soil. Clay (size < 0.002 mm) amount in the soil samples ranges from 19%
to 25%; Silt (size 0.002 to 0.075 mm) in the soil samples is 25% to 37%
and Sand (size 0.075 to 0.475 mm) in the soil samples is 23% to 31%.
While Gravel (size > 4.75 mm) in the soil samples is 19% to 31%.
Analysis shows that the soil is sandy soil with less 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 40.3 to 42.1%.
Water Holding Capacity (WHC): Water holding capacity (WHC) of soil
samples of the study area ranges between 49.3 to 56.1 % and these being
sandy soils are not 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 1.43 to 1.49 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.

3.6 Terrestrial Ecology (Flora)
The structure and type of vegetation depends on climatic conditions and
physiography of an area. Climate of the study area is arid to semi arid and
suited for the growth of selected variety of vegetation.
The contents of this subsection are based secondary data obtain from local
forest department. List of floral diversity is presented in Table 3.14.
3.6.1 Common Crop Plants
Common cultivated crop plants in the study area include: Rabi season

REIA of Narayan Organics Pvt. Ltd.-Unit-II 3-11
gram and Kharif (July to October) - paddy; Sugar cane and vegetables are
also grown at some places.
3.6.2 Ecological Stresses
Human needs for settlement and commercial activities like farming,
industries, infrastructure (roads, canals, power lines, railways etc.) have
forced him to encroach on natural vegetation i.e. forests. Even the open
areas left for plantation/green cover at times have been occupied by
encroachers/slums resulting in stress on environment.
3.6.3 Terrestrial Wild Life
Because of being in arid / semi arid zone and lack of well developed forest
cover, the study area lacks in mammalian life and is the home of dry,
scrub jungle loving animals, best suited to the climate of arid and open
land. Avifauna and reptiles found in the study area and area around it.
This is compiled on the basis of sighting during field survey in the area
and also from the information collected from villagers and forest personnel
working in the area.

Table 3.15 depicts the zoological name and abundance rating of wild
animals found in the study area and its adjoining area.
3.7 SOCIO ECONOMIC AND LAND USE
3.7.1 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 a degree of inter play between
these two. 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; Forests, Culturable
land, Culturable waste land and area not available for cultivation.
Culturable land is further classified as: irrigated and unirrigated. Area not

Anticipated Environmental Impacts & Mitigation Measures
4.1 GENERAL
Predicting the net contribution on overall qualitative environmental
indicators require environmental impact assessment study for the proposed
units. Prediction of impacts 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. Depending on the nature of the impact,
suitable management plans are devised.
Proposed unit is for dyes and dyes intermediate manufacturing. As such it
becomes important to estimate the peak incremental concentrations of
pollutants caused due to the emissions from the proposed Narayan
Organics plant. Section 2.9 in Chapter 2 of this report discusses the
pollution sources from the proposed plant.
Mathematical models are the best tools to quantitatively describe the
cause- effect relationship between source of pollution and different
components of environment.

4.2 IMPACT DURING CONSTRUCTION AND OPERATION PHASE
The impact assessment has been addressed for the following attributes,
which may get affected due to the proposed activities of the project.
Impact on topography;
Impact on Air Environment;
Impact on Water Environment;
Impact on Noise;
Impact due to solid waste generation;
Impact on terrestrial ecology;
Impact on aquatic ecology
4.3 IMPACT ON TOPOGRAPHY
The project activities include excavation of soil in the plant area and
construction of the plant and storage facilities. The area of the proposed
plant is flat. Very minor or no Leveling would be required for the
construction of the proposed plant. No tree plantation affected since plant
will be come in industrial area. During the construction, excavated soil will
be restored to its original shape. Thus the impact during the construction is
reversible, for short terms and insignificant.
During the operation phase of the project, no impact is envisaged on the
topography.
4.4 AIR ENVIRONMENT
4.4.1 Construction Phase
The source of air emission during the construction will include dust from
site cleaning and construction activity and dust from excavation of the
plant area. These emissions are expected to result in change in baseline air
San Envirotech Pvt. Ltd-Ahmedabad
REIA of Narayan Organics Pvt. Ltd., Unit-II 4-3
quality, primarily in the working area only. 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 protect workers. To mitigate the impact due to Suspended Particulate
Matter (SPM), regular sprinkling of the water will be done along with the
construction activities.
4.4.2 Operational phase
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.
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. Apart
from the above, other activities associated with any project, viz.,
transportation of raw materials and finished products, storage facilities and
material handling within the plant premises may also contribute to air
pollution.
4.4.3 Sources of air pollution
In the proposed project of pigment manufacturing, point sources emitting
gaseous pollutants include three nos. of flue gas stacks and two nos. of
process gas stacks. The major air pollutants, identified from this industry,
are SPM, SO2 and NOx from flue gas stacks and ammonia (NH3) from
process gas stacks.
4.4.4 Emissions
In the operational unit Bio Fuel (Briquettes) will be used for Boiler, Thermic
fluid heater and Hot air generator. The rate of fuel consumption and other
details are shown in Table 4.1.
San Envirotech Pvt. Ltd-Ahmedabad
REIA of Narayan Organics Pvt. Ltd., Unit-II 4-4
Since the bio fuel will be used, the gaseous emission will be well within
GPCB norms and simultaneously, there will be less impact on the air
Environment due to fuel combustion. The unit also proposes to provide
adequate scrubbing system to the reactors so that ammonia emission will
also be well within the GPCB norms. However, similar types of stacks were
monitored to get the information about emission characteristics including
the emission rates of SPM, SO2 and NOx. The emission rates of SPM, SO2
and NOx and effluent gas characteristics as well as stack details for the
proposed units are presented in Table 4.1. A built-in scrubber will be
installed with spray dryer system. Fugitive emissions of organic gases may
occur through the leaks from pumps, valves etc. However, the industry
being of small scale the fugitive emissions and their impacts would be
negligible.
4.4.5 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
San Envirotech Pvt. Ltd-Ahmedabad
REIA of Narayan Organics Pvt. Ltd., Unit-II 4-5
- 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 B class during Day time and D
class during Night time. The mean mixing height considered for prediction
is 180 m as mean minimum and 1500 m as mean maximum. Average
micro meteorological data of December-2010 to February-2011 is
presented in Table 4.2.
4.4.6 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.
San Envirotech Pvt. Ltd-Ahmedabad
REIA of Narayan Organics Pvt. Ltd., Unit-II 4-6
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
- Stack-tip downwash
- Gradual plume rise
- Buoyancy-induced dispersion, and
- Complex terrain treatment and consideration of partial reflection
- Plume reflection off elevated terrain
- Building down wash
- Partial penetration of elevated inversions is accounted for Hourly source emission rates, exit velocity, and stack gas temperature
In the present case, prediction of impacts has been carried out December-
2010 to February-2011 on 24-hourly basis in the entire study area of 10
km radius using the Gaussian model.
Gaussian air dispersion models were used to estimate the ambient air
quality levels at different monitoring stations due to stack emissions. Only
two stability conditions based on the meteorology aspects were used to
calculate the theoretical maximum ground level concentration. Comparing
the actual data and data generated from mathematical modeling, it
San Envirotech Pvt. Ltd-Ahmedabad
REIA of Narayan Organics Pvt. Ltd., Unit-II 4-7
highlights that the stability condition E & A-B were predominant in the
region. The maximum ground level concentration of SPM, SO2, NOX & NH3
were away from the source. Using the estimated stack emission data and
wind speed directions, a mathematical model was prepared to establish the
ground level concentration in the region.
4.4.7 Predicted GLCs of proposed dyes plant
It is predicted that the maximum contribution in GLCs, with units operating
at full capacity, is 3.469 μg/m3, 0.817 μg/m3 and 0.661 μg/m3 for SPM, SO2
and NOx respectively and for NH3 maximum GLC will be 1.351 μg/m3. The
point of maximum concentration by unit would be 2.0 km from centre of
industry in E direction for SPM, SO2 and NOx and 1.0 km from centre of
industry in E direction for NH3.
4.5 WATER ENVIRONMENT
Impact on water environment due to the proposed dyes project will be
1. Due to demand for raw water and
2. Due to disposal of treated effluent from the plant.
These are discussed below:
4.5.1 Water Demand
Construction phase
During the construction activities there will be no adverse impact on the
quality of water. No disposal of construction waste outside the plant and no
leaching are anticipated.
Operational Phase
The main source of the water will be ground water. The unit will install its
own bore wells within premises to satisfy its fresh water demand.
Necessary permission will be obtained from CGWA.
San Envirotech Pvt. Ltd-Ahmedabad
REIA of Narayan Organics Pvt. Ltd., Unit-II 4-8
The fresh water demand will be for domestic, gardening and industrial
purpose. Industrial purpose includes water demand for boiler, cooling,
process, washing and RO reject, etc.
The estimated total quantity of the fresh water requirement will be 683.0
KLD. Figure-2.1 in Chapter 2 provides water balance of the proposed
project. However, efforts have to be made to conserve water as much as
possible. Also Chapter 5 proposes some additional mitigation measures to
minimise the raw water consumption. In view of these factors the impact
on water environment due to water use is assessed to be insignificant.
4.5.2 Wastewater Generation – Operational Phase
The industrial wastewater generation from the proposed project will be
about 448.0 KLD. The unit proposes to install its own Effluent Treatment
Plant comprising of primary and secondary treatment units followed by
tertiary treatment facilities. After meeting GPCB norms, the treated effluent
will be disposed to ECP channel to Mahi River.
4.5.3 Effluent Treatment within Unit
Narayan Organics proposes a well-designed Effluent Treatment Plant
providing three stages Physico-Chemical followed by aeration and pressure
sand filter and activated carbon filter treatment.
Wastewater stream is divided into two parts (i) concentrated stream and
(ii) General stream.
Concentrated stream will be neutralized and then treated at Effluent
Treatment Plant along with general stream. After meeting effluent
discharge norms, entire quantity of treated effluent will be discharge to
ECP channel to Mahi River. Whereas the utility stream will not contain any
kind of pollutant load and directly use for plantation and gardening or
mixed with treated effluent.
San Envirotech Pvt. Ltd-Ahmedabad
REIA of Narayan Organics Pvt. Ltd., Unit-II 4-9
The COD/BOD concentration in the influent of the plant ETP will be about
2000-2500 mg/L and 800-1000 mg/L respectively. After treatment COD/
BOD concentration in the effluent becomes COD: 150-250 mg/L and BOD:
40-50 mg/L whereas the TDS in the influent is reduced by approximately
10% in the effluent. Details of effluent quality are given in Table 2.6. The
ETP flow diagram is given in Fig. 2.2 of chapter-2.
Impact on Water Environment
The unit will make all efforts to minimize the quantity of wastewater
generation by adopting proper segregation, collection and treatment
philosophy to ensure that the effluent disposal shall have minimal impacts
on the receiving environment. Thus, considering the treatment facilities
proposes by the unit, it can be said that there would be chances of minor
impact on the water environment.
4.6 NOISE LEVEL IMPACT
4.6.1 Construction Phase
The noise produced during construction may have significant impact on the
existing ambient noise levels. The major work will be carried out during the
daytime. The construction equipment may generate high noise, which can
affect the personnel operating the machines. Use of proper personal
protective equipments will mitigate any adverse impact of noise generated
by such equipment.
The noise level in the working environment is compared with standards
prescribed by ISO 3746. The acceptable limit for each shift being of 8-hour
duration, the equivalent noise level exposure during the shift is 90 dB(A).
Hence noise generation due to excavation may affect workers, if equivalent
8 hours exposure is more then the safety limit. The noise level likely to be
generated during excavation, loading, transportation of construction
San Envirotech Pvt. Ltd-Ahmedabad
REIA of Narayan Organics Pvt. Ltd., Unit-II 4-10
materials will be in the range of 90-100 dB(A) and this will occur only when
all the equipment operate together and simultaneously. This will be a
remote possibility. The worker in general are likely to be exposed to an
equipment noise level of 80-90 dB(A) in an 8 hour shift for which all
statutory precautions as per laws will be taken into consideration.
4.6.2 Operational Phase
The main sources of noise within the plants are: boiler and spray dryer
blower. 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 other sources of noise are the movement of
vehicles along the road. The typical industrial noise sources are given in
Table 4.4.
The results of monitoring carried out in the region have been presented in
Chapter-3. The permissible levels in the ambient environment as well as
industrial environment are also presented in Chapter 3. The results are
below the standards prescribed for Industrial environment. It can be
concluded that the impact on noise environment will be long term but
insignificant. The noise standards specified by regulations shall be met. The
mitigation measures being followed / proposed for minimising impacts on
noise quality are provided in chapter 5.
4.7 SOLID WASTE MANAGEMENT
The main source of hazardous waste generation will be ETP sludge. Other
sources will be discarded barrels/bags and spent/waste oil. As discussed in
Chapter-2, the unit proposes to provide adequate area i.e. 800 sqm. for
the storage of hazardous waste having roof cover, impervious floor and
leachate collection system. ETP sludge will be sold to cement
manufacturers or sent to approved TSDF site whereas discarded
barrels/bags will be properly cleaned and sold to approved end users and if
San Envirotech Pvt. Ltd-Ahmedabad
REIA of Narayan Organics Pvt. Ltd., Unit-II 4-11
excess then reuse within premises. Spent/waste oil will also be sold to
CPCB approved recyclers.
Thus, after taking adequate steps for the hazardous waste storage, there
will be minor impact on the environment due to proposed project activities.
4.8 SOCIO-ECONOMIC IMPACTS: CONSTRUCTION & OPERATIONAL PHASE
Operational phase of the units covers the entire life span of the plant.
Hence the impacts of the operational phase extend over a long period of
time. These impacts include employment generation, effects on basic
infrastructure etc.
The development of industrial area will result in overall prosperity in the
area in terms of infrastructure development, employment generation,
indirect employment communications, medical facilities etc.
The unit will have direct employment of about 90 persons, which will
increase further. It will provide indirect employment as well as
development of well developed road network connecting nearby villages,
faster development of communication facilities and medical facilities.
Pigment manufacturing industry may impose some occupational health
effect on the workers. However, adequate preventive and protective
measures will be assured by the management to avoid the same.
In view of the above the overall impacts on socio-economic environment
due to the pigment manufacturing unit is long term and positive in nature.

Chapter - 5 Environment 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, off set or reduce impacts to acceptable levels
during implementation and operation of projects. The integration of such
measures in to 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 there will be almost minor
impact on the surrounding environment due to proposed project.
However, for the abatement of environmental pollution, M/s. Narayan
Organics Pvt. Ltd., Unit-II would adopt several measures, which are
summarized in this chapter.
M/s. Narayan Organics Pvt. Ltd., Unit-II is equally concern for production
as well as pollution control. The unit has already done the homework to
develop the efficient Environmental Management Plan for its proposed
project. This will be put in to existence as per the requirement after the
execution of the proposal.
San Envirotech Pvt. Ltd-Ahmedabad
REIA of Narayan Organics Pvt. Ltd., Unit-II 5-2
5.2 OBJECTIVES OF EMP
The objectives of the Environmental Management Plan are summarized
here under,
• 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 project of M/s. Narayan Organics Pvt. Ltd. covers
following aspects:
• Description of proposed mitigation measures 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.
5.4 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.
San Envirotech Pvt. Ltd-Ahmedabad
REIA of Narayan Organics Pvt. Ltd., Unit-II 5-3
This model EHS system as suggested 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 of change
- 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 Narayan Organics
would be able to integrate the requirements of ISO-14001 into the overall
management system.
5.5 AIR ENVIRONMENT
Environmental management plan for an industrial activity is an integral
part of EIA and has been proved to be an effective tool to mitigate the
adverse environmental impacts arising due to the establishment and
operational phase of the industry. This gives a sequential approach with
feasible options to ensure that the mitigation/control measures overcome
the adverse impacts of the industrial activity and thus achieve the
sustainable operation.
In order to mitigate the adverse environmental impact due to the
operation of the proposed unit following measures are recommended.
San Envirotech Pvt. Ltd-Ahmedabad
REIA of Narayan Organics Pvt. Ltd., Unit-II 5-4
5.5.1Measures for reducing stack emissions
Narayan Organics proposes to establish five stacks to meet the emission
requirement due to various operations. Out of the same three will be flue
gas stacks attached individually to boilers, thermic fluid heaters and hot
air generators. Whereas process gas stacks are attached to process
reactors from where ammonia gas will be liberated. Adequate stack height
of 30.0 m and 15.0 m will be provided to flue gas stacks and process
stacks respectively.
Since biofuel/Coal proposed to be used, less pollution will be generated.
However, on the precautionary bases the unit proposes to install dust
collector as air pollution control measures.
The unit also proposes to install two stage water scrubber followed by acid
scrubber as air pollution control measures to absorb ammonia gas likely to
be generated as process gas.
Thus, air pollution control measures proposed by the unit will be adequate
to obtain gaseous emission norms recognized by GPCB.
Moreover, Narayan Organic’s maximum contribution in ambient air quality
will be 3.469 μg/m3, 0.817 μg/m3 and 0.661 μg/m3 for SPM, SO2 and NOx
respectively and for NH3 maximum GLC will be 1.351 μg/m3. The point of
maximum concentration by unit would be 2.0 km from centre of industry
in E direction for SPM, SO2 and NOx and 1.0 km from centre of industry in
E direction for NH3. As per the analysis of similar type facilities, emissions
coming out from the stack of boilers, heaters and also on the basis of
characteristics of the fuel, it is observed that SO2, NOx and PM emissions
are well within the permissible limits (as prescribed by CPCB). However, in
order to achieve further reduction, it is suggested that regular
maintenance and periodic tuning of the burner system should be done to
San Envirotech Pvt. Ltd-Ahmedabad
REIA of Narayan Organics Pvt. Ltd., Unit-II 5-5
ensure proper atomization and subsequent minimization of any unburned
combustibles. Besides reduction in particulate emissions, it would also
result in better operating efficiency. For this, combustion process may be
further improved by adopting following measures:
Optimization of combustion aerodynamics should be done using a flame
retention device.
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 may also implement energy conservation measures through
installation of heat recovery systems. This would reduce the fuel
consumption and in turn the emissions.
Injury Symptoms and Pollutant Dose Thresholds of Tolerance by
Sensitive Species of Plants
Pollutant Threshold Dose Plant Injury Symptoms
Sulphur Dioxide (SO2)
0.70 ppm (1820 μg/m3) for 1 hr.; 0.18 ppm (468 μg/m3) for 8 hr.; 0.008 – 0.017 ppm (21/44 μg/m3) for growing season
Interveinal necrotic blotches Red brown dieback or banding in pines
Nitrogen Oxides (NOX)
20 ppm (38 x 103 μg/m3) for 1 hr.; 1.6 – 2.6 ppm (3000-5000 μg/m3) for 48 hr.; 1 ppm (1900 μg/m3) for 100 hr.
Interveinal necrotic blotches similar to those by SO2

What type of plants should be planted?
There are certain plants that are sensitive to certain air pollutants, e.g.
gladiolus is sensitive to HF. However, it is difficult to identify species that
are selectively tolerant to certain air pollutants. Moreover, an industrial
area invariably emits several pollutants rather than a single one. Green
belts as a pollution sink hence, should aim at cultivating plants that are
tolerant to air pollutants in general, rather than tolerant to SO2, to HF or
to O3, etc. Scattering of a few known sensitive plants (including selectively
sensitive species for SPM, SO2, and NOX) within a green belt however, do
carry out an important function of indicating the presence of pollutants,
which the tolerant would not indicate.
Characters of plant including shapes of crowns considered necessary for
effective absorption of pollutant gases and removal of dust particles are as
follows:
For absorption of gases
1. Tolerance towards pollutants in question, at concentrations, that are
not too high to be instantaneously lethal;
2. Longer duration of foliage;
3. Freely exposed foliage, through
a. adequate height of crown,
b. openness of foliage in canopy,
c. big leaves (long and broad laminar surfaces, with larger leaf area
index),
d. large number of stomatal apertures,
e. Stomata well exposed (in level with the general epidermal surface).
For removal of suspended particulate matter
1. Height and spread of crown;
San Envirotech Pvt. Ltd-Ahmedabad
REIA of Narayan Organics Pvt. Ltd., Unit-II 5-7
2. Leaves supported on firm petioles;
3. Abundance of surfaces on bark and foliage, through
a. roughness of bark,
b. epidermal outgrowths on petioles,
c. abundance of auxiliary hairs,
d. hairs or scales on laminar surfaces,
e. Stomata protected (by wax, arches / rings, hairs, etc.).
Note: All tolerant plants are not necessarily good for green belts, e.g.
Xerophytes with sunken stomata can withstand pollution by avoidance but
are poor absorbers of pollutants due to low gaseous exchange capacity.
While making choice of plant species for cultivation in green belts,
weightage has to be given to the natural factor of bio-climate. Moreover,
the species should be indigenous to that area and most of them should be
quick growing. Attention should also be focused to their economic or
aesthetic value. A good green belt should have a well-proportioned mix of
trees and shrubs of different heights, and evergreen and deciduous.
Hence, considering the bio-climatic characteristics of the project region,
the following plants might be used for green belt development:

How and Where to be planted: The standard practice for green belt
development involves planting of saplings in pits of substantial dimensions
i.e. 1m x 1m x 1m for big trees and almost half of these dimensions for
smaller trees and shrubs. The pits should then be filled with earth, sand,
silt and manure in the pre-determined proportions. Saplings planted in
such pits are to be watered liberally. The growing plants should be
nurtured for three years and should be cared and protected against any
damage caused by domestic elements.
For effective removal of pollutants, it is necessary that
1. Plants grow under conditions of adequate nutritional supply (for
health and vigour of growth);
2. Absence of water stress (to maintain openness of stomatal apertures
and form of epidermal structures); and
3. Plants are well-exposed to atmospheric conditions of light and
breeze (i.e. away from engineering structures hindering free flow of
air) to maintain free interaction with gases.
Industry has sufficient space to systemically develop green belt, the above
mentioned plant species should be planted wherever the space and
conditions permit. In order to increase efficiency of the green belt, shrubs
should be inserted between big trees. If space permits for more than one
row, smaller trees should be planted inside while taller trees on the
outside with respect to emission sources.
5.5.2 Measures for fugitive emissions
The fugitive emissions of organic chemicals and VOCs come from leakage
through valves, fittings, pumps, etc. Though this is not expected to be
significant, adopting the following measures may reduce it further:
San Envirotech Pvt. Ltd-Ahmedabad
REIA of Narayan Organics Pvt. Ltd., Unit-II 5-10
Regular maintenance of valves, pumps and other equipment should be
undertaken to prevent leakage and thus minimize the fugitive emissions of
VOCs.
In case the units undertake modernization, design features as suggested
in Table 5.1 for new equipment may be considered.
5.6 WATER ENVIRONMENT
The mitigative measures for minimizing the impacts on water environment
in general includes following:
- Minimization of water use
- Segregation and collection philosophy for effluent to minimize waste
generation and facilitate treatment as well as recycle
- Treatment philosophy to achieve mandated standards
- Reuse/recycle and disposal
Some of the measures, which are to be implemented, include:
- Use equipment wash down waters as makeup solutions for subsequent
batches.
- Use high-pressure air-water jet for equipment cleaning to reduce the
amount of wastewater generated.
- Reducing the actual process water consumption by way of improvement
in operation of processing units
- Ensuring proper operation and maintenance schedule for the ETP.
- Artificial recharge of water.
5.6.1 Segregation and Collection Philosophy
A segregated drainage system is suggested wherever feasible to achieve
following objectives:
- Optimise the treatment process
San Envirotech Pvt. Ltd-Ahmedabad
REIA of Narayan Organics Pvt. Ltd., Unit-II 5-11
- Minimise generation of secondary wastes such as sludge
- Facilitate reuse/ recycle of process effluents and consequently minimise
impacts associated with disposal
The segregation of effluents in small units is not always practical and
feasible. It has to be implemented after careful study of effluents at each
unit. The emphasis has to be on resource recovery potential. The units
shall utilize the concept of waste minimization circles. The suggestions
provided in Comprehensive Industry Document by CPCB should also be
applied depending on technical feasibility.
5.6.2 Wastewater Treatment
Entire effluent will be divided into three streams (i) Concentrated stream
and (ii) General stream. The unit proposes to provide its own Effluent
Treatment Plant comprising of primary and secondary treatment units
followed by tertiary treatment units.
Concentrated stream will be separated and then neutralized. After
neutralization, it will be mixed with general stream and treated at Effluent
Treatment Plant. Whereas third stream i.e. utility stream which will not
contain any kind of pollution load, will be used for gardening or plantation
within premises and/or stored in treated effluent collection sump. Entire
effluent after confirming effluent discharge norms will be discharged to
ECP channel to Mahi River.
5.6.3 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.
San Envirotech Pvt. Ltd-Ahmedabad
REIA of Narayan Organics Pvt. Ltd., Unit-II 5-12
Thus approximately 100% of the water use for the factory is available for
artificial recharge from rainfall which can be put into the ground water
reservoir directly by construction of “Injection tube well”. The opener
must be fitted with filter pit.
The location of such injection bore well must be decided considering the
slope of the ground in the factory premises so that the accumulated
flowing rain water can be injected in to bore well.
Surface Geology and Geohydrolocal condition is prime importance in
successful implementation of artificial recharge scheme. The regional
hydro geological map provide details of ground water aquifer system,
ground water potential, ground water flow and chemical analysis of water
in different aquifers. It is suggested to do above survey before deciding
the location of such inject bore well. It will helpful for selection of location
and proper designing of artificial injection bore wells.
5.7 SOLID WASTE MANAGEMENT
Solid Waste management includes following:
- Measures to minimize waste generation
- Operation of waste handling, treatment and disposal facilities
As discussed in Chapter-2, adequate area for the storage of hazardous
waste will be provided having roof covered impervious floor and leachate
collection system. The ETP sludge will be sent to cement manufacturers or
sent to approved TSDF site for the disposal whereas discarded
bags/drums/liners will be sold to approved reusers or reused within
premises for the storage of sludge and spent/waste oil will be sold to CPCB
approved recyclers. Thus, hazardous waste management plan proposed by
the unit will be adequate.
However, the Waste Management plan should also include:
San Envirotech Pvt. Ltd-Ahmedabad
REIA of Narayan Organics Pvt. Ltd., Unit-II 5-13
- Waste Inventory
- Classification of waste
- Packaging, Storing and Transporting Wastes to Disposal site
- Selecting a Hazardous Waste Management Facility – Final Disposal
- Data Management and Reporting
- Contingency Plan
- Personnel Training
- Waste Minimization
The condition specified in the Authorization from GPCB shall be followed.
The manifest system shall be implemented for control and record keeping.
5.8 NOISE ENVIRONMENT
The main sources of noise within the plant are: boiler, manufacturing
activities, transferring pumps and material handling systems. Additional
noise will be generated due to installation of new machineries and
equipments however, these impacts will be very minor and temporary in
nature. The impact on the environment during the operational phase will
be long term but, of insignificant quantity.
To minimize the noise pollution, the unit proposes the following noise
control measures:
• Noise suppression measures such as enclosures, buffers and/or

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.
5.9 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 it 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 be 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 and having minimum of leaf fall.
San Envirotech Pvt. Ltd-Ahmedabad
REIA of Narayan Organics Pvt. Ltd., Unit-II 5-15
• 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 have extensive greenbelt plantation in 11220 sqm, which is
around 33% of total land area. Local spices are planted and survival rate
is more than 65%.
5.10 RESOURCE CONSERVATION / WASTE MINIMIZATION
The units shall also implement the concept of waste minimization circle.
Good Housekeeping or proper housekeeping practice makes the system
easier and less costly. Some of these are as follows:
• 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.
The process emission containing Ammonia mainly. The Ammonia gas gets
absorbed in the water and results in Liq. Ammonia solution (12–15%) or
reaction with spent sulfuric acid and convent to Ammonium Sulphate as by
products. This Ammonia solution will be recovered as By- Product and sold
to actual end users. Thus, this is the step towards waste minimization and
resource conservation.
5.11 HEALTH & SAFETY

San Envirotech Pvt. Ltd-Ahmedabad
REIA of Narayan Organics Pvt. Ltd., Unit-II 5-17
5.11.1Possibility 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 advice 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
San Envirotech Pvt. Ltd-Ahmedabad
REIA of Narayan Organics Pvt. Ltd., Unit-II 5-18
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.
5.11.2Preventive 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.
5.12 OCCUPATIONAL HEALTH PROGRAMME
Some of the philosophies underlining the occupational health programme
are discussed below.
San Envirotech Pvt. Ltd-Ahmedabad
REIA of Narayan Organics Pvt. Ltd., Unit-II 5-19
M/s. Narayan Organics Pvt. Ltd. will employ well qualified and experienced
safety Manager and make 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.
5.12.1Hazard Communication and Chemical Safety
The information on the hazards of the materials to be used will be
provided to the workers for the proposed project of M/s. Narayan Organics
Pvt. Ltd. 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 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
San Envirotech Pvt. Ltd-Ahmedabad
REIA of Narayan Organics Pvt. Ltd., Unit-II 5-20
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 selected group of employees at the proposed
facility will receive first aid training to provide an immediate response and
medical care for injuries.
5.13 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:

REIA of Narayan Organics Pvt. Ltd., Unit-II 6-3
& other facilities, potential hazards associated with the spillage and
release of hazardous chemicals.
The assessment of vulnerable zones resulting from an accidental release
of hazardous substance into the environment is one of the key elements
of risk analysis. Quantification of the effects of such releases requires,
data of the chemicals stored or handled in the area, quantities stored,
operating parameters, quantity that would be released in case of an
accident, meteorological conditions and physical attributes of the area.
The starting point of risk analysis study is the identification of hazards
and selection of scenarios that are then addressed for further
consequence analysis.

6.3 QUANTITIES OF HAZARDOUS MATERIALS
As mentioned in Section-6.2, various hazardous chemicals will be 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.
Table - 6.1: Facilities for Storage of Chemicals
Name of Chemical Quantity, MT/month Storage Facility
Sulphuric Acid (98%) 30 MSRL
Spent Acid (20-22%) 25 MSRL
6.4 HAZARDS DUE TO LEAKAGE OR CONTAINMENT
Since the proposed project is for the manufacturing of dyes and dyes
intermediates, various hazardous chemicals will be required to be
handled.
SAN Envirotech Pvt. Ltd, Ahmedabad
REIA of Narayan Organics Pvt. Ltd., Unit-II 6-11
Hazardous chemical to be handled and stored at the plant is in liquid
form. In the event of leakage or accidental release of these chemicals, it
will create only localized effects within the short distances from fixed or
spread pool in case of fire. There is possibility that release of some
hazardous chemicals may form vapour cloud which can move towards
wind direction and may explode in the event of fire if mass and
concentration of air and vapour mixture is within the LEL and UEL limits.
However, mass of vapour and air mixture may not be adequate to
generate explosive mass.
Storage and handling of hazardous chemical will not pose any hazardous
situation if these are handled or stored correctly with adequate safety
provisions and fire fighting facilities. Therefore, suitable safety measures
including fire fighting facilities will be provided at the plant to attend any
emergency due to accidental release of these hazardous chemicals.
Among the hazardous inventories, there are few potential toxic
materials that can form toxic vapour cloud in unlikely event of release.
6.5 MAXIMUM CREDIBLE ACCIDENT SCENARIOS
The plant will be dealing with some hazardous substances i.e. Sulphuric
Acid, Ortho Nitro Benzene, Iso butyl alcohol described in details. This is
in the form of liquid and considered as odorous. Subsequently, their
consequence due to thermal radiation will be confined within short
distances. If released quantities are not ignited, therefore, vapour
formation can result in vapour and air mixture and may generate
explosive mass which can explode if it gets the source of ignition. Toxic
cloud of hazardous chemicals may also be formed and moved towards
wind direction.
6.5.1 Methodology For Selection of Accident Scenarios
In this study, following steps are followed for scenario selection for risk
analysis study:
SAN Envirotech Pvt. Ltd, Ahmedabad
REIA of Narayan Organics Pvt. Ltd., Unit-II 6-12
• The hazardous materials to be handled at the plant and the
associated hazards have been identified and assessed.
• Operating and storage conditions of handling and storage of
hazardous materials are studied.
• An assessment is made of what inventories can get released
accidentally.
• Release rates are calculated considering different cases. For further
analysis of selected release sources, representative failure modes
and failure sizes are identified.
6.5.2 Maximum Credible Accident Scenarios Following maximum credible scenarios have been selected for
consequence analysis as a result of accidental releases:
Sr. No.
Type of Release Outcome Cases Considered
Formation of pool and thermal radiation due to fire Vapour cloud explosion 1. Release of Solvent Dispersion of toxic cloud of vapours Vapour cloud explosion
2 Acid leakages Dispersion of toxic cloud of vapours
6.5.3 Consequence Analysis
Consequence analysis for the selected accident scenarios has been
carried to estimate the vulnerable zones. Thermal radiation distances
have been computed based on various heat flux values vulnerable to
men and materials at the plant, while modelling of dispersion cloud is
based on IDLH (Immediately Dangerous for Life and Health) values. On
identification of vulnerable zones for failure cases, measures can be
taken for risk mitigation and to eliminate or minimize damage to the
plant and injury to personal.
SAN Envirotech Pvt. Ltd, Ahmedabad
REIA of Narayan Organics Pvt. Ltd., Unit-II 6-13
6.6 PROBABLE HAZARDS & RISK
From the preliminary risk assessment study carried out for Narayan
Organics Pvt. Ltd. Some of the possible hazards have been identified.
The likely accident scenarios considered are given below:
Sr. No.
Scenario Vulnerability Zone
Remarks
1. 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.
2. 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.
6.7 METHODOLOGY, APPROACH AND DAMAGE CRITERIA FOR RISK
ASSESSMENT
Consequence analysis is that part of risk analysis, which considers
individual failure cases and the damage, caused by each failure case. It
is done to predict the outcome of potentially serious hazardous
SAN Envirotech Pvt. Ltd, Ahmedabad
REIA of Narayan Organics Pvt. Ltd., Unit-II 6-14
accidents to man and material in and around the plant boundary limits.
The advantages of carrying out consequence analysis are given below:
• To improve plant layout (for new projects and for expansion of
existing one)
• To meet statutory requirements
• Protection of public in the nearby areas (no residential/ inhabited
near by)
• Disaster management planning
• Training tool
The findings of a consequence analysis provide information about
hazardous effects resulting from an accident scenario. In addition,
Methods for dealing with possible catastrophic events are also provided.
6.7.1 HAZARDS EVALUATION: EXPOSURE To TOXIC DUSTS / VAPORS
Leakage in process plant from failure of nozzles, joints (flange joint),
welding failures or dripping from non-holding valves/glands or dusts
generation during charging of solids at times goes unnoticed. If the
leaky dust or fluids being toxic and odorless it is a potential source of
risk, which may cause fatal/serious hazards.
Liquids with high saturation vapor pressures evaporate faster because
the evaporation rate (mass/time) is essentially proportional to the
saturation vapor pressure. In the case of vaporization into stagnant air,
the vaporization rate is proportional to the difference between the
saturation vapor pressure and the partial pressure in the stagnant air.
6.7.2 LIQUID POOL EVAPORATION OR BOILING
The pool boiling cases may be encountered during heavy leakage in
enclosed area (dyke wall of tanks) and with heat source nearby
(ambient or fire) the vapor can explode or catch fire (in case the
material is flammable and sparks/flame contact is made).
6.7.3 PLANT LEAKAGE IN CONFINED SPACE
A chemical fluid spill is a common type of process incident and can lead
to potentially serious accident. If the spilled material gives rise to
SAN Envirotech Pvt. Ltd, Ahmedabad
REIA of Narayan Organics Pvt. Ltd., Unit-II 6-15
hazardous vapor or aerosol these may interact with plant environment
resulting in explosion or harm to plant’s personnel/ damage to plant
equipment/machinery (if vapors are toxic/ corrosive/inflammable). Most
chemical spills do not have such dramatic sequences but they must all
be handled carefully and correctly. Plant of Narayan Organics Pvt. Ltd.
will open with natural ventilation.
6.7.4 DAMAGE CRITERIA
In order to appreciate the extent of damage produced by various
accident scenarios, it is appropriate to discuss the physiological/
physical effects of toxic fluid exposure/thermal radiation intensities due
to spillage causing subsequent fire. The thermal radiation usually results
in burn on the human body and damage to plantation. Furthermore,
inanimate objects like equipment, piping, cables, etc. may be affected
and may aggravate the situation further.
Consequence analysis has been carried out for selected failure cases.
Consequence analysis quantifies vulnerable zones for a likely incident
and once the vulnerable zone is identified for an incident, measures are
proposed to eliminate damage to plant and potential injury to personnel.
6.8 RISK MITIGATION MEASURES
For risk mitigation/reduction, attempts should be made either to reduce
inventories that could get released in the event of loss of containment
or failure likelihoods 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 the plant, the following salient suggestions and
recommendations are made:
• On site and off site emergency response plan should be prepared
and circulated to concern persons.

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, then the DISASTER is said
to have occurred.
M/s. Narayan Organics Pvt. Ltd., Unit-II is the proposed unit for pigment
manufacturing. The unit proposes to manufacture Copper Pthalocyanine
Blue (CPC Blue), Pigment Alpha Blue and Pigment Beta Blue of 700.0 TPM,
75.0 TPM and 200.0 TPM capacity respectively. There will also be
generation of Ammonium Carbonate Solution (12-15%) as by-product up
to 600.0 TPM. Thus, total production capacity of the unit including by-
product will be 1575.0 TPM.
As described in 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 best efforts to manage an emergency situation in the prevention
of 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.
SAN Envirotech Pvt. Ltd, Ahmedabad
REIA of Narayan Organics Pvt. Ltd.,Unit-II 7-2
7.2 PROBABLE HAZARDS AND 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 an 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 on the
hazards/risk assessed, safeguards provided, residual risks, if any, and
the role to be played by them in the event of an emergency.
• To be ready for the mutual aid if need rises to help the neighbouring
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 in case of an emergency
occurring outside.
• To inform authorities and mutual aid centres 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
normality.
• 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 measures to stop its
reoccurrence.
SAN Envirotech Pvt. Ltd, Ahmedabad
REIA of Narayan Organics Pvt. Ltd.,Unit-II 7-3
• To ensure safety of the work force before they 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 plan 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 THE PLAN
• The plan will set into action immediately after a fire or other hazard
occurs in and/or around the plant
• Fuel storage facility will be situated away from the manufacturing plant
and will follow all rules and regulation
• All the electrical fittings will be of explosion proof fitting
• All necessary fire-fighting arrangements will be provided near the
storage area
SAN Envirotech Pvt. Ltd, Ahmedabad
REIA of Narayan Organics Pvt. Ltd.,Unit-II 7-4
7.6 THE UTILITY, 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 neighbouring 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 centres
• Communication equipment
• Alarm system
• Personal protection equipment
• Fire fighting facilities, equipment and supplies
• Spill and vapour release control equipment and supplies
• Medical facilities, equipment and supplies
• Monitoring systems
• A media Centre
• 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
SAN Envirotech Pvt. Ltd, Ahmedabad
REIA of Narayan Organics Pvt. Ltd.,Unit-II 7-5
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 before hand, so that these resources can be mobilized, if the
time comes to do so.
