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
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,

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

private agricultural lands and wastelands. The buffer zone area contains common
varieties of flora, but no endangered species. The biotic data indicates normal arid
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
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:
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.

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.
