EXECUTIVE SUMMARY

I. PROJECT DESCRIPTION

M/s IndianOil Petronas Pvt. Ltd. has commissioned a LPG Import/Export Terminal at Ennore

in the year 2012 to meet the LPG requirements of Tamil Nadu, Karnataka and Andhra

Pradesh. The Terminal was set up with the aim of increasing LPG availability and

eliminating transportation costs by bullet trucks. Blended LPG from the terminal caters to the

LPG demand in the southern region of India.

Propane/Butane is pumped from Ennore Jetty to the Terminal, blended to produce LPG, The

LPG is transferred to bullet tankers & Indane Bottling Plant, Athipattu for distribution. The

Terminal is operated on a single shift production basis to produce 5,76,000 TPA of LPG. The

present project proposal is to expand the production capacity to 23,04,000 TPA by increasing

the shifts of operation from one to three and by installing four additional Truck Loading

Filling (TLF) bays.

Need For the Project and Its Importance

India is the fourth largest consumer of LPG (15 million tonnes per year) in the world

following USA, China and Japan. With home deliveries of 3 million LPG cylinders per day

(900 Million/year), India is also the third largest domestic consumer of LPG.

With a combined bottling capacity of 0.4 million TPA, Tamil Nadu was facing a LPG deficit

of 0.8 million TPA and this shortfall was met by transporting LPG from Mangalore by road.

IPPL has commenced operations at Ennore to meet the LPG requirements of Tamil Nadu,

Karnataka and Andhra Pradesh. The IPPL facility at Ennore was set up with the aim of

increasing LPG availability.

The results of the monitored data indicate that the ambient air quality of the region in general

is in conformity with respect to the norms of National Ambient Air Quality standards

(NAAQS) of CPCB, with present level of activities.

Noise Environment - The noise monitoring has been conducted at six (6) locations in the

study area. The highest noise level was found to be 52.8 dB (A) during day time. The

lowest noise level was found to be 41.1 dB (A) during night time. However the noise

levels are found to be well within the CPCB standards.

Water Environment - Six (6) groundwater samples and one (1) surface water sample

within the study area were considered for assessment. The water samples were collected

and analyzed during 2015. The analysis of ground water results indicate that the average

pH ranges in between 7.28 -8.12, TDS ranges from 424 mg/l - 1225 mg/l, Total Hardness

ranges from 190 mg/l - 710 mg/l, iron content ranges from 0.07mg/l – 0.16mg/l, nitrate

content ranges from 5 mg /l – 42 mg/l was observed.

The analysis of Surface water results indicate that the pH of 8.06, TDS of 31304 mg/l,

Total Hardness 5400 mg/l, DO 6.1 mg/l was observed. Total Coliform of 542/100 ml and

Faecal Coliforms of 358/100 ml was observed.

Soil Environment - Six locations within the study area were selected for soil sampling. It

has been observed that the pH of the soil was ranging from 7.52 to 8.52, Conductivity of

the soil ranges from 0.066 to 0.824 mS/cm. Since the EC value is less than 2000 µS/cm,

the soil is said to be non-saline in nature. Soil organic content varied from 0.51 to 0.96 %

which indicates the very low level of organic matter.

Ecological Environment - There are no endemic and endangered species of flora and

fauna within the study region. There is no wild life sanctuary, national park or bird

sanctuary with in the 15 km radius of the project site.

Socio-Economic Environment - According to 2011 census, Tiruvallur district had a

population of 37,28,104. With a sex-ratio of 987 females for every 1,000 males, much

above the national average of 929. A total of 4,05,669 were under the age of six,

constituting 2,08,449 males and 1,97,220 females. Scheduled Castes and Scheduled

Tribes accounted for 8, 21,646 and 47,243 of the population respectively. Average

literacy rate of Tiruvallur district in 2011 were 84.03 compared to 76.94 of 2001. The

district had a total of 9,46,949 households. There were a total of 12,47,918 main workers,

comprising 60,436 main cultivators, 1,73,150 main agricultural laborer’s, 9,72,590 other

workers, 2,90,136 marginal workers, 13,008 marginal cultivators, 97,436 marginal

agricultural laborers.

III. ANTICIPATED ENVIRONMENTAL IMPACTS & MITIGATION MEASURES

Ambient Air Environment - No emissions will be generated during the operations as the

entire process will be carried out through close circuit piping from storage area to filling

shed. The only point sources of emissions will Boiler, D.G sets & Fire Engines, they have

been fitted with stacks of adequate height to disperse the pollutants.

Impact on Water Environment - Total water requirement for M/s IPPL during proposed

expansion is 187 KLD, which will be sourced through CMWSSB, for the existing operation

water is sourced through CMWSSB. There is no requirement for drawl of surface /

groundwater or diversion from other sources.

During the proposed expansion, 51.2 KLD sewage will be generated, which will be treated in

the existing Sewage Treatment Plant (treatment capacity 60 KLD). DM Plant and Cooling

Tower blowdown (13.422 KLD) will be treated using RO plant & permeate (10.47 KLD) will

be recycled to DM plant (8.182 KLD) and the Cooling Tower (2.288 KLD). RO reject (2.95

KLD) & Boiler Blow Down (1 KLD) will be diverted to solar evaporation ponds.

Impact on Ambient Noise Environment - Activities within the Terminal (loading /

unloading operations) will not cause any disturbances to people living in the proximate areas

outside the plant boundary. The only source of noise within the Terminal is DG operation.

DG sets are placed within acoustic enclosures. Necessary greenbelt with total area of 39.29%

has been provided to contain the noise emissions.

Solid and Hazardous Waste Generation – STP sludge generated will be used as manure for

green belt development. Used oil generated from DG set operation will be disposed to

TNPCB Authorized Used Oil Recyclers.

Details on Fire Protection System and Safety Measures – The Propane/Butane/LPG

import-export terminal of IPPL has an extensive network of pressurized fire hydrant system.

This system enables to fight fire anywhere within Terminal and to cool vessels and structures

to ensure their safety during an incident involving incidents of dangerous heat flux from a

burning fire. Fire Fighting Facility Alarms have been provided to display in Fire Pump House

and Main Control Room for operation of firefighting pumps, deluge valves, MV sprayers, fire

hydrants and monitors. A dedicated Fire Alarm network with manual call point type fire

alarm in the hazardous as well as in non-hazardous area has been provided. Adequate number

of Dry Chemical powder, CO2 Extinguishers and Fire Buckets are installed within the

terminal. State of the art Quartzite Bulb, Gas, Flame, Laser, Heat and Smoke detectors are

also installed throughout the terminal. Combination of Fire Detectors, Fire Alarm, Fire

Extinguishers and Fire hydrant system will ensure that conditions for major accident hazards

are never allowed to occur.

Impact on Socio-economic Environment - The present proposal is aimed at meeting the

LPG demand of the South India by increasing the throughput of LPG. Once the increased

throughput is achieved, the daily fuel requirements of people residing in Tamil Nadu,

Karnataka & Andhra Pradesh will be met and penetration of LPG supply in rural areas to the

tune of 75% can be achieved. It has positive impact on the social-economic conditions of the

area.

IV. ENVIRONMENTAL MONITORING PROGRAMME

Environmental monitoring plan for operation phases of the proposed increase of LPG

throughput has been prepared to ensure efficiency of implemented mitigation measures. In

order to implement the proposed environmental management program efficiently within the

organization, periodical monitoring as per statutory guidelines and mid course

corrections/actions, environmental cell will be established for successful implementation of

monitoring plan.

12


V. BENEFITS OF PROPOSED PROJECT

The proposed project shall yield following benefits:

• Increase in production of LPG will aid in meeting the demands of various LPG

bottling plants spread across the states of Tamil Nadu, Andhra Pradesh and

Karnataka .

• Improved penetration of LPG in rural areas will help in replacing the use of

biomass fuels like fire wood, cow dung, etc., with LPG which will in turn improve

the air quality, the health and quality of life of people.

• To help in raising LPG coverage in rural areas to 75%.

• To meet the demands of industrial sector and also in complementing the various

measures taken by Government of India, like Make in India Campaign.

• LPG can be used as a substitute by industries instead of other fossil fuels like coal,

diesel, furnace oil etc, which emit more pollutants and greenhouse gases thereby

protecting the environment.

• Auto Gas is currently marketed as an economical & environment friendly fuel.

The current Auto Gas price in Chennai is 36.65 Rs/Ltr as opposed to Petrol (60.08

Rs/Ltr) & Diesel (47.28Rs/Ltr). Increasing its availability will remove bottle-

necks in its demand versus sales scenario & pave way for India to become one of

the leading Auto LPG markets of the world in the next few years.

• At present LPG is supplied to neighboring Indane Bottling Plant at 400MT/day.

Tripling the throughput at the Terminal will increase the quantity of LPG pumped

to the Indane Bottling Plant thereby increasing the availability of domestic LPG to

the populace residing in Chennai.

• No land acquisition is required for construction of proposed LPG filling facilities.

The socio-economic impacts linked to the acquisition of land and structures will

not appear in the project.

• During construction phase of the project no significant impact on environment are

anticipated.

• The proposed project will generate direct and indirect employment opportunities

mainly during the construction phase. Local semi-skilled and unskilled laborers

will get direct employment in the construction phase. This is a positive impact of

the proposed project.

13


• The proposed LPG increase in LPG throughput will provide cleaner fuel, which

will create healthy environmental conditions.

VI. ENVIRONMENT MANAGEMENT PLAN
