EXECUTIVE SUMMARY

1. INTRODUCTION

Chennai Petroleum Corporation Limited, formerly known as MRL (Madras Refineries

Limited); is one of the largest and most integrated refineries in south India producing fuel

products, lubricants & additives.

CPCL's product range is wide and varied; providing fuel like Diesel, Kerosene, LPG, ATF and

Bitumen. CPCL also provides high quality feedstock's for other industries like Propylene,

Superior Kerosene, Butylenes, Naphtha, Paraffin Wax and Sulphur.

1.1. MANALI REFINERY

The Manali refinery was originally designed for processing 2.5 MMTPA (Million Metric

Tonnes per Annum) of Darius Crude from Iran. The construction of the refinery was

completed in a record time of 27 months, at a cost of Rs.43 crore. It was constructed

without any cost or time overrun. The refinery was commissioned in the year 1969 and has

consistently been making profits from the second year of operations, and paying dividends

from the third year.

The capacity of CPCL's Manali refinery was increased from 2.5 MMTPA to 2.8 MMTPA in

1980, through de-bottlenecking steps. Subsequently, the refining capacity was doubled to

5.6 MMTPA in 1984-85 at a cost of Rs.170 crore. Amoco Inc. disinvested its equity holding

in favour of the GoI in 1985. In March 1993, the overall refining capacity at Manali was

enhanced further to 6.5 MMTPA. The company has commissioned most part of the 3

MMTPA refinery expansion cum modernization project in March 2004. Presently Refining

capacity of Manali Refinery stands at 10.5 MMTPA.

1.2. NEED FOR THE PROJECT

Presently CPCL receives its crude oil from oil tankers berthed at Chennai Port Trust

through a 30” pipeline commissioned in 1969. In 1996, Engineers India Limited (EIL) had

done a study on the operational health of this existing 30” crude oil pipeline from Chennai

Port Trust to its Manali refinery. The study by M/s. EIL in 2008, in had indicated that

there is no significant corrosion damage on the external surface of the pipeline. Considering

Page 3: FOR PROPOSED 42’’ CRUDE OIL PIPELINE PROJECT FROM … · Executive Summary- CPCL Pipeline Project E - 2 the densly populated Built up area through which the pipeline passes, the

Executive Summary- CPCL Pipeline Project

E - 2

the densly populated Built up area through which the pipeline passes, the presence of busy

railway line in close vicinity and finally extreme difficulty in taking up repairs or corrective

maintenance in the event of any failure, EIL has advised that pipeline be rerouted having

ROU/ROW.

1.3. PROPOSED PIPELINE CONVEYING SYSTEM

To meet the requirements of the Manali Refinery and considering the recommendation of

EIL, a new 42” crude oil pipeline is proposed to be laid from Chennai Port to Manali

Refinery along the route of the proposed Port Connectivity Project. The detailed route

alignment survey has been completed; soil geo-tech studies and other pre-project activities

are carried out. CPCL is closely co-ordinating with Chennai Port Trust, Tamilnadu Road

Development Corporation, Indian Oil Corporation (Pipelines Division) and other agencies

for this project. The new pipeline is expected to be laid within 12 months of obtaining right

of way. The indicative project cost is about Rs.126 crores.

In order to augment this Scenario, M/S. Chennai Petroleum Corporation Limited (CPCL) has

appointed M/S. Hubert Enviro Care Systems Pvt Ltd (HECS), Chennai to assess the likely

impacts arising out of proposed project activities and to prepare an Environmental Impact

Assessment & Management plan report for their proposed program. The study was

completed earlier in the year 2005, and on the submission of the same to the Ministry,

CPCL was directed to update the EIA incorporating the present baseline data via their letter

dated 7th August, 2008. One season (post monsoon) baseline data was collected during the

months of January to March 2009, and the EIA report was updated based on the collected

primary and secondary data. It was advised by the State CRZ committee to conduct studies

on PM 2.5 and PM 10 levels prescribed by Govt. of India (through recent Gazette

notification on national Ambient Air Quality Standards dated 18th November 2009). One

season (Pre monsoon) baseline data was collected during the months of April to June 2010,

and the EIA report was updated based on the collected primary and secondary data.

1.4. OBJECTIVE AND NEED FOR EIA

The proposed project attracts EIA, as per CRZ Notification 1991/2011. The distinct features

of the methodology for the EMP project were as follows,

Page 4: FOR PROPOSED 42’’ CRUDE OIL PIPELINE PROJECT FROM … · Executive Summary- CPCL Pipeline Project E - 2 the densly populated Built up area through which the pipeline passes, the

Executive Summary- CPCL Pipeline Project

E - 3

1. The existing environmental quality was assessed based on primary and secondary data.

Wherever data was not available to make fair assessment, actual monitoring in the field

was carried out.

2. Potential sources of pollution were identified and anticipated pollution was quantified.

3. Potential environmental impacts including potential benefits were identified and

assessed.

4. An EMP, comprising proposed environmental management strategies and appropriate

further enhancements recommended by HECS, was formulated to maintain and

enhance the environmental quality around the project site.

Keeping in view the nature of activities envisaged, size of the project and the various

environmental guidelines available, it was decided to cover an area of 10 km radius from

the center of the proposed unit for the purpose of Environmental Management Studies

(EMS).

2. PROJECT DESCRIPTION

3-1. At the selected sites, soil samples were collected using Auger/core cutter into the

soil at a depth of 90 cm. The soil texture was brownish sand. pH of 10% solution varied

from 6.63 to 6.98. The infiltration rate varied from 15.3 – 16.6. The organic content

were in the range of 2.02- 2.12%., available nitrogen was observed in the range of 0.4-

0.48%, phosphorus 0.24- 0.32% and potassium 0.2-0.3%

3.8. SOCIO ECONOMIC ENVIRONMENT

Predominantly the socio economic is typical urbanized mixed industrial community

with typical below average social indicators. The amenities like drinking water supply,

power supply, and medical facilities are available within the study area.

3.9. ECOLOGICAL RESOURCES

The core zone area is devoid of endangered species while the buffer zone contains

private agricultural lands and wastelands. The buffer zone area contains common

varieties of flora, but no endangered species. The biotic data indicates normal arid

Page 15: FOR PROPOSED 42’’ CRUDE OIL PIPELINE PROJECT FROM … · Executive Summary- CPCL Pipeline Project E - 2 the densly populated Built up area through which the pipeline passes, the

Executive Summary- CPCL Pipeline Project

E - 14

conditions and absence of any special or endangered species. Also the tourist spot or

any historical monuments or forest reserves are not present.

4. IMPACT PREDICTION

For proper assessment of impact it becomes essential to understand various activities

which may result in environmental pollution during construction and operation of the

proposed pipeline. The Study of Impact is necessary to identify and assess various

environmental impacts caused on the existing environs by the proposed scheme, with a

view to arrive at an objective assessment of the possible harmful fall-outs and to plan

necessary corrective and remedial measures well in advance to contain these within the

prescribed limits set by Ministry of Environment and Forests (MOEF) and Tamil Nadu

Pollution Control Board (TNPCB).

4.1. CONSTRUCTION PHASE

Dust generated during excavation of pipeline in the ROW may affect

communities in the immediate vicinity of construction sites

As the pipeline is not crossing any surface water bodies and only crosses

navigational canal viz. Buckingham canal, no impact is envisaged on the

surface water body along the pipeline alignment during the operational

phase.

As evident during construction phase, the excavation, laying and other

works will create noise sources.

4.2. OPERATION PHASE

Spillage is possible in case of pipeline failure. However adequate safety

measures are built in to prevent spillage and contain any damage.

4.3. IMPACT ON COASTAL REGULATION ZONE (CRZ)

Proposed pipeline alignment will fall within 500 m from the tidal area and as per the

CRZ notification 2011, the stretch of the project alongside the Bay of Bengal comes

under the category of Classification II (CRZ II), which means the areas that have

Page 16: FOR PROPOSED 42’’ CRUDE OIL PIPELINE PROJECT FROM … · Executive Summary- CPCL Pipeline Project E - 2 the densly populated Built up area through which the pipeline passes, the

Executive Summary- CPCL Pipeline Project

E - 15

already been developed up to or close to the shoreline. Hence the proposed project

comes under CRZ II.

4.4. PROPOSED MITIGATION MEASURES

To safeguard the pipeline and facilities routine activities, there will be

some restriction on the land use within the ROW strip. No permanent

structure and deep-rooted trees will be allowed.

Distinctly colored stake markers will be placed on both sides of the ROW

at a regular interval of every 10m.

Corner stones will be laid to demarcate the pipeline route in the ROW.

The quality of welds will be done by the radio-graphical examination with

the help of X-ray / Gamma radiation.

The entire pipeline will be subjected to “Holiday Testing” for checking the

soundness of coating. Any damages, coating defects can be detected by

holiday testing.

Leak detection system in the pipeline is proposed, so as to immediately

identify the leakage;

Remote Control Valves would be provided for stoppage of pipeline

operation and isolation.

Regular patrolling of the pipeline is proposed.

Cathode protection is proposed to prevent corrosion.

Adequate temporary canopies and sprinkling of water on surface areas

alongside the construction works would be done. These measures would

control the dust pollutions.

Protective measures like earplug / ear muffs will be provided in high

level of noise generating areas and this would mitigate impacts on

construction workers.

5. RISK ASSESSMENT

Risk assessment is a tool to help in the analysis of the risk posed by the different

project activities to the surrounding population and also quantification of the same.

The objectives of the risk assessment are

Assessing risk levels due to the operations

Identification of the risk mitigation measures to bring the potential risk within

acceptable range

To suggest general safety improvement measures for the facility.

To help generate accident free hours that in turn increase production

To identify emergency scenarios and suggest mitigation measures.

5.1. HAZARD IDENTIFICATION

This is a tool that is very useful for conducting a risk assessment as it helps in

identification and detailing of hazards that exist in a given project. Crude oil is a

naturally occurring flammable liquid consisting of a complex mixture

of hydrocarbons of various molecular weights and other liquid organic

compounds. On release of crude oil jet fire, flash fire and vapour cloud explosion

may occur.

5.2. RISK MITIGATION MEASURES

The important risk mitigation measures for pipeline system are given below:

Buried crude oil pipelines in same ROW should be provided with suitable

coating, wrapping and cathodic protection system for corrosion

prevention.

SCADA system should be installed to monitor pipelines during operation.

Pipeline should be pressure tested at 1.5 times the maximum pressure

once in a year. Test pressure should be held at least for 24 hours:

Page 18: FOR PROPOSED 42’’ CRUDE OIL PIPELINE PROJECT FROM … · Executive Summary- CPCL Pipeline Project E - 2 the densly populated Built up area through which the pipeline passes, the

Executive Summary- CPCL Pipeline Project

E - 17

Ground patrolling by walking in ROW should be done regularly by

personal survey to reduce chances of sabotage of pipeline and

encroachment of ROW.

Communication system should be properly tested before commencing

pipeline operation.

Periodic intelligent pigging and pipe-to-soil potential survey should be

carried out in accordance with codes and best industry practice to

monitor pipeline health.

Pig launching and receiving facilities provided at the beginning and end of

each pipeline should be suitable for intelligent pigging.

All welds in the pipelines should be radio graphed.

Pipeline marker signs should be placed in ROW and especially where

pipeline crosses highway and water body.

6. DISASTER MANAGEMENT PLAN

Due to the large volumes of flammable fluids formed on liquid spillage, the emergency

scenarios envisaged require initial action to stop the transfer operation in a quick, safe

and controlled manner.

6.1. ONSITE EMERGENCY PLAN

Workers would be provided earplugs, safety shoes and goggles as

protective devices during construction.

7.2. OPERATION PHASE

The pipeline design will strictly follow the protocols laid down by the

OISD.

Thickness of soil cover will be decided and also keeping in view the land

use pattern along the alignment as well as population distribution. This

will ensure the safety of the population

The pipeline would be subjected to quality control through pressure

testing during construction and operational phase. The pipeline would be

monitored and controlled from Station Control Center (SCC).

Warning signs will be placed at road crossings and other appropriate

locations as required.

Temporary traffic control will be established where necessary at road

crossings and junctions.

To monitor status of the pipeline with respect to corrosion / erosion,

intelligent pig will be used.

Development of a green belt in and around the pipeline area is an

effective way to check pollutants and their dispersion into the

surrounding areas.

Impressed current based cathodic protection system will be provided in

order to mitigate external corrosion of the main lines.

Corrosion inhibitor chemical will be injected in the pipeline during its

operation to prevent internal corrosion.

To monitor the extent of environmental impact of the proposed project,

periodical monitoring of pollutant loads generated from the pipeline will

be done.

An environmental management cell (EMC) will be looking after all the

environment-related activities in the pipeline route.

Training shall be provided to all personnel for promoting awareness

among the employees with respect to emergency scenarios.

Identifying and evaluating the environmental impacts caused during

emergency situations.

8. PROJECT BENEFITS

The proposed pipeline project will be beneficial for the environment. The project will

result in the following benefits:

Pipeline transport is more eco-friendly than rail / road. Due to the pipeline project,

the level of pollution would be reduced compared to road / rail transport, the

pollution level would be more.

The cost of the pipeline is less as compared to the cost augmenting road and rail

transport. The operational cost of the pipeline is less than the cost of transporting

fuel by trucks and tank wagons.

Transportation problems associated rail movement such as non-availability of

wagons; spillage losses and derailment delays would be eliminated.

Pipeline transportation reduces the fuel required for transporting products by road

and rail, and also reduces handling and transport losses.

The pipeline would bring about savings in Capital as well as recurring costs.
