Executive Summary

1. Introduction

Indian Oil Corporation Limited (IOCL) operates one of its largest oil refineries at Koyali

(near Vadodara) in Gujarat, Western India. The refinery was commissioned in the year

1965 with a capacity of 3.0 MMTPA. Over the years, the capacity of the refinery has

gradually been increased to 13.7 MMTPA with augmentation of old primary Atmospheric

Units (AU-I, AU-II and AU-III) and addition of new primary units viz. Atmospheric Unit-IV

in 1978 and AU-V in 1999 as well as augmentation of AU-IV in 2000.

Gujarat refinery IOCL owned a land of 434 Acres at survey no 771 to 795 at Dumad

with Existing facilities of LPG marketing terminal commissioned during Nov 2002 and

IOTL white oil terminal commissioned in the year 2012.

LPG marketing Terminal occupies land of approximately 62 Acres in 434 Acres at

Dumad Village, Vadodara Savili Road, Dumad. It is about 3 Km from Dumad Approx ~8

Kms away from Gujarat Refinery (GR) of IOCL and situated between Vadodara-Savli

Road. The operating processes carried out at the Terminal are receipt of LPG bulk, its

storage in 6 mounded storage vessels having max storage capacity of 8300 MT,

distribution of bulk LPG by loading Tank trucks and filled LPG cylinder after their filling

at carousel machines. The quantity of LPG to be handled in existing facility is 0.50

MMTPA. The existing plant is under operation with GPCB consent obtained vide: AWH

68449, valid up to 18/11/2019 & PESO license obtained vide S/HO/GJ/03/498(S2126),

Valid up to 31 March 2019.

IOTL Terminal occupies approximately 48 Acres of 434 Acres land. The existing

terminal obtained EC in 2001 from MoEF vide: J-11011/8/2001-IA-II (I).The facility

comprises of storage tanks for 5 No Gasoline Tanks, 4 No Diesel tanks, 3 No Kerosene

Tank, 3 No Ethanol Tanks. The nearest railway station is Pilol 1.4 km towards NNE.The

existing plant is under operation with GPCB consent obtained vide: AWH 65930, valid

Summary of analytical results of soil quality monitored at 8 locations are presentedbelow:

The pH of the soil samples ranged from 7.25-8.22. Indicating that the soils

are almost neutral in nature.

Conductivity of the soil samples ranged from 100.5-245 μS/cm. As the EC

value is less than 2000 μS/cm, the soil is found to be non-saline in nature

VI. Biological Environment

Trees and shrubs play an essential role in maintaining an ecological equilibrium and

improving the livelihood of people in the dry regions. Vegetation of a particular area

depends upon the interaction of various natural biotic and abiotic factors including

Temperature, Rain fall, Humidity, Soil type, plants, animals, micro-organisms of that

particular area in which they grow live and influence one another. The study area is

moderately rich in vegetation. The review of the study area indicated that 174 floral

species have been identified within the vicinity of the project site (refer Table 3-20 of

EIA report). The bio diversity richness map of the study area is given in Figure-7.

VII. Socio Economic Environment

Vadodara District is a district in the eastern part of the state of Gujarat in western

India. The city of Vadodara (Baroda), in the western part of the district, is the

administrative headquarters. Vadodara District covers an area of 7526 km². It had a

population of 3,641,802 with population growth of 19.87% as of 2001 census. As of

Draft EIA Report

24

2011 it is the third most populous district of Gujarat (out of 33) with 4,165,626, after

Ahmadabad (7,214,225) and Surat (6,081,322). The district is bounded by

Panchmahal and Dahod districts to the North, Anand and Kheda districts to the West,

Bharuch and Narmada districts to the South and Chhota Udaipur to the East.

A socio-economic study was undertaken in assessing aspects which are dealing with

social and cultural conditions, and economic status in the study area. The study

provides information such as demographic structure, population dynamics,

infrastructure resources, and the status of human health and economic attributes like

employment, per-capita income, agriculture, trade, and industrial development in the

study area. The study of these characteristic helps in identification, prediction and

evaluation of impacts on socio-economic and parameters of human interest due to

proposed project developments. The parameters are:

Demographic structure

Infrastructure Facility

Economic Status

Health status

Cultural attributes

Awareness and opinion of people about the project and Industries in the area.

VIII. Anticipated Environmental Impacts

a. Water Environment

The total raw water requirement is 560 TPH (considering the requirement of

integrated project at Dumad). Raw water storage pond of total 10 days storage of

water was considered for sizing the pond. Raw water treatment facilities include:

chemical dosing system, multi grade filter, activated carbon filter and Reverse

Osmosis plant.

Total 211.7 KLD of effluent of is anticipated and will be treated in dedicated proposed

combined ETP’s of 190 KLPH and 150 KLPH. Treated water will be passed through

RO and Permeate is used for Cooling tower and greenbelt.

b. Air Environment

Adequate measures will be taken to control Air Pollution through installation of

Electrostatic Precipitators and Fuel Gas Desulphurisation (FGD) as a part of CPP

system. Following will be measured through installation of online analysers to

measure SOx, NOx, CO, Hydrocarbons and Particulate Matter.Total Maximum GLCs

from the proposed Stack Emissions are given in Table-12.

It was observed that the maximum incremental concentration observed due to

proposed expansion for PM, SO2 and NOx are 2.108 µg/m3, 7.031 µg/m3 and 7.301

µg/m3. So it can be concluded that even after the expansion of the plant the impact

envisaged is minimum. Vehicular modelling was also carried out but since the

number of vehicles increased is marginal per day and no major impact envisaged on

Air environment.

c. Noise Environment

All equipment in the plant produce 40 to 55 dB(A) after control measures and

equipment are designed/operated to have a noise level not exceeding 85 to 90 dB(A)

as per the requirement of Occupational Health and Safety Administration Standard

(OHSAS). In addition, since most of the noise generating equipment would be in

closed structures, the noise transmitted outside would be still lower and for any other

case of higher noise sufficient safety ear plugs and ear muffs will be provided to the

employees.

d. Land Use

The proposed expansion is within the existing IOCl Dumad complex and the

proposed activity doesn’t change the land use classification of the site.

IX. Environmental Monitoring ProgramA monitoring schedule with respect to AAQ, Water, Wastewater quality, Noise Quality

as per CPCB/MoEF&CC/GPCB shall be maintained.

X. Pollution Control Measures

Fugitive air emissions from captive power plant will be controlled by ESP & FGD will

be provided to meet the norms as required by CPCB. Adequate stack height will be

provided.

Municipal solid waste will be composted within the facility.

Hazardous waste will be stored and disposed off to authorized vendors for landfill.

Fly ash will be disposed off to cement manufacturing processes.

The Industrial effluent generated will be treated in inhouse ETP. The sewage from

domestic use will be treated in ETP and treated water will be recycled back into the

system.

The proposed wastewater treatment system will be a Zero Liquid Discharge (ZLD).Hence, there will be no discharge to land environment.

XI. Greenbelt Development

Project site is an existing unit with shrubs and small trees. There will be clearance of

land envisaged for proposed projects. Existing Green belt is over a stretch of 33

Acres with approx 25000-30000 trees and adequate measures will be taken to

maintain the greenbelt of 111 Acres for the proposed expansion. The lists of species

suggested for green belt is given in Table-13. Green belt development scheme is

given in Table-14.
