EXECUTIVE SUMMARY

I. PROJECT DESCRIPTION

Bharat Petroleum Corporation Limited (BPCL) has an oil receiving terminal at Karur in

Karur district of Tamil Nadu for the purpose of receipt, storage and dispatch of

petroleum products such as Motor Spirit (MS), High-Speed Diesel (HSD) and Superior

Kerosene (SKO). The Karur oil receiving terminal receives petroleum products from

PETRONET CCK (Cochin - Coimbatore - Karur) pipeline distribution network. The

existing storage units consist of different types of aboveground and underground

storage tanks. Dispatch from the installation is done by road tankers and train

wagons. Oil receiving terminal with an existing capacity of 136770 KL and now

proposes to install 4 nos. of above ground tanks with aggregate storage capacity of

6916 KL (2 x 858 KL for Ethanol and 2 x 2600 KL for Biodiesel). After expansion, the

storage capacity will increase to 143686 KL.

NEED FOR THE PROJECT AND ITS IMPORTANCE

The Government plans to increase the ethanol blend ratio from 5% to 10% and

Biodiesel in many different concentrations. The most common are: B6 to B20 (6% to

20% biodiesel blended with petroleum diesel) and B5 (5% biodiesel, 95% petroleum

diesel). In compliance with the directives of the Govt. of India, the company has

undertaken to supply blended fuels that serve to reduce the import burden on account

of crude petroleum and also to reduce vehicle exhaust emissions. Petrol is to be blended

with ethanol and diesel with biodiesel for supply to retail outlets in accordance with

appropriate BIS standards. To this end, BPCL proposes to increase the onsite storage

capacity of ethanol and introduce storage of biodiesel within the site.

The project will directly generate some employment both during construction and

operation phase and some indirect employment is also likely to be generated due to this

project. This will help to enhance the economic condition of this region. The project will

help for the further development of infrastructure facilities in the region. The project

will also provide indirect employment to unskilled, semi-skilled and skilled categories.

II. DESCRIPTION OF THE ENVIRONMENT

Primary baseline environmental monitoring studies were conducted during 19 June

2017 to 17 July 2017 and details are as follows:

Meteorology - The predominant wind direction during the study period was from West

Southwest to East Northeast direction with average wind speed of 2.29 m/s. Maximum

relative humidity is around 92%. The minimum temperature recorded is 39°C while

maximum temperature is 41°C.

Air Environment- The maximum and minimum concentrations of PM10 were recorded as

80.2 µg/m3 and 28.1 µg/m3 respectively. The maximum concentration was recorded at the

Vaiyapuri Nagar -Karur and the minimum concentration was recorded at Nochipalayam.

The maximum and minimum concentrations for PM2.5 were recorded as 41.4 µg/m3 and

10.4 µg/m3 respectively. The maximum concentration was recorded at the Vaiyapuri Nagar

-Karur and the minimum concentration was recorded at Nochipalayam. The maximum and

minimum SO2 concentrations were recorded as 13.6 µg/m3 and <5.0. The maximum

concentration was recorded at Vaiyapuri Nagar -Karur. The maximum and minimum NOx

concentrations were recorded as 28.1 µg/m3 and 8.3 µg/m3. The maximum concentration

was recorded at Vaiyapuri Nagar -Karur and the minimum concentration was recorded at

Nochipalayam. The maximum CO concentrations were recorded as 0.53 mg/m3 and the

minimum was BDL (<0.1). The Lead concentrations were recorded as BDL (<0.1) in all

locations. The maximum THC concentrations were recorded as 24 µg/m3.

Noise Environment - Noise levels during daytime were found to be in the range 49.1 to

58.3 dB (A). The maximum noise level was observed to be 58.3 dB (A) at Vaiyapuri Nagar

– Karur and a minimum of 49.1 dB (A) were observed at Nochipalayam. Noise levels

observed to fall in the range 37.9 to 46.8 dB (A) during the night time. A maximum of 46.8

dB (A) was observed at Vaiyapuri Nagar – Karur and a minimum of 37.9 dB (A) were

observed at Nochipalayam. Measured noise levels are observed to be in compliance with

prescribed standards for ambient noise for the respective applicable categories.


x

Water Environment - The analysis of groundwater results indicate that the average pH

ranges in between 6.92 – 7.95, TDS ranges from 804 mg/l - 6735 mg/l, Total Hardness

ranges from 270 mg/l - 1660 mg/l, iron content BDL(<0.05), nitrate content ranges from

2.7 mg /l – 57 mg/l was observed.

Soil Environment: The soil results were compared with soil standards. It has been

observed that the pH of the soil was ranging from 7.59 to 9.21 indicating the soils are basic

in nature. The conductivity of the soil ranges from 0.073 to 0.533 mS/cm. Since the EC value

is less than 2000 µS/cm, the soil is said to be Non-saline in nature. The texture of the soil

sample is predominantly loam. Soil organic content varied from 1.22 to 2.04 % which

indicates the very low level of organic matter. The available nitrogen content ranges

between 158 to 236 mg/kg in the locality and the value of phosphorus content varies

between 29.6 to 65.8 mg/kg. This indicates that the soil has very high quantities of Nitrogen

and Phosphorus. The potassium content varies from 146 to 218 mg/kg which indicates that

the soils have high quantities of potassium. From the above observations, it was found that

the soil in the Study area shows moderate fertility.

Ecological Environment: There is no Wildlife Sanctuary / National Park found in the

study area. There are no endemic and endangered species of flora and fauna within the

study region.

Socio-Economic Environment: As per 2011 census, the study area consists of 43,510

persons inhabited. The literacy level of the study area is 73.22%. As per 2011 census

records, altogether the main workers works out to be 52.54% of the total population.

The marginal workers constitute to 2.83% of the total population respectively.

III. ANTICIPATED ENVIRONMENTAL IMPACTS & MITIGATION MEASURES

Ambient Air Environment - Particulate and gaseous emissions from vehicle movement

will be reduced by the Proper maintenance of internal roads, Green Belt Development

on the periphery and open areas. DG sets & fire engines are the only point sources of

emission, which will be operated intermittently at emergency conditions. DG sets have

been fitted with stacks of adequate height as per CPCB guidelines to provide a natural

dispersion of pollutants.

Impact on Water Environment - Minimal quantity of sewage will be generated, it will

be treated through a septic tank and soak pit within the project premises. Stormwater


xi

management will be provided.

Impact on Ambient Noise Environment - The source of noise generation within

the terminal are DG sets operation and vehicular traffic. DG sets are fitted with

acoustic enclosures and will be operated during power shutdown. Greenbelt has been

developed around the terminal, which works as a noise barrier for noise.

Solid and Hazardous Waste Generation - Municipal solid waste generated from

the BPCL terminal, which is disposed of as per provision of Municipal Solid

Waste Management & Handling Rule, 2000. Oily sludge will be generated at the

time of cleaning of tanks once in every 5 years. It will be treated through

bioremediation technique. Other hazardous wastes like spent batteries, waste oil,

empty drums of oil/chemicals, fluorescent tubing etc. are disposed of in accordance

with approved safe procedures.

Details on Fire Protection System and Safety Measures - The existing

firefighting facilities at the tank farm will be extended to the proposed new tanks as

per OISD STD 117. The automatic medium velocity sprinkler system will be provided

for all fixed roof tanks. The operational activities for normal operations as well as

emergency services for the new tanks will be integrated within the existing terminal

management system. The proposed tanks for Biodiesel and Ethanol will tie-in to the

existing hydrocarbon receiving and transfer suction lines.

Impact on Socioeconomic Environment - The existing BPCL Terminal after expansion

shall meet increased demand for Petroleum products in nearby districts of Karur, Tamil

Nadu. It will have a positive impact on the socio-economic conditions of the area.

IV. ENVIRONMENTAL MONITORING PROGRAMME

Environmental monitoring plan for operation phases of the proposed expansion of

Karur terminal 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, the environmental cell is established for successful

implementation of the monitoring plan.

V. BENEFITS OF PROPOSED EXPANSION

The project will improve supply position of the Petroleum products in Tamil Nadu,

which is vital for economic growth as well as improving the quality of life. The

improved petroleum supply will have strong logistical support for delivering the

products to customers at better quality and better price. Availability of product in the

vicinity of demand location will be reduced price. Delivery distance by tankers which in

turn will reduce trucks on the road reducing the vehicular load on the already strained

public roads, thereby reducing the noise pollution as well as air pollution at local levels

and also reduced the probability of accidents on the roads due to less movement of

tank trucks. Establishment of large developmental projects improves the availability of

the physical infrastructures like approach roads, drainage, communication and

transportation facilities etc.

VI. ENVIRONMENT MANAGEMENT PLAN

Air Environment Management - Adequate greenbelt has been developed within the

existing terminal to mitigate the air and noise pollution arising due to movement of


xiii

vehicles at the existing terminal. Regular monitoring of DG stack and ambient air

quality monitoring will be carried out.

Water Environment Management - Sewage generated from the terminal will be

disposed of through septic tank & soak pit. Oily wastewater from the washing of the

facilities will be treated in the Oil Water Separator (OWS). No wastewater will

be discharged outside the premises.

Noise Environment Management - The source of noise generation within the

terminal are DG sets operation and vehicular traffic. DG sets are fitted with acoustic

enclosures. Greenbelt has been developed around the terminal, which works as a noise

barrier.

Solid & Hazardous Waste Management - Municipal solid waste generated at

the terminal will be disposed of through the local body. Oily Sludge is generated during

tank cleaning in every five years. It will be treated through bioremediation

technique. Other hazardous wastes like spent batteries, waste oil, empty drums of

oil/chemicals, fluorescent tubing etc. are disposed of in accordance with approved safe

procedures.

GREENBELT DEVELOPMENT

The terminal has a well-developed greenbelt area of about 33 % in total plot area.

RISK ASSESSMENT AND DISASTER MANAGEMENT PLAN

Hazard Identification, Risk Assessment and Disaster Management Plan of existing BPCL

terminal at Karur have been carried to ensure acceptability of the on-site and off-site

risk exposures as per Petroleum & Natural Gas Regulatory Board (PNGRB) guidelines.

ENVIRONMENTAL MANAGEMENT PLAN BUDGET – The budget for implementation of

mitigation measures and environmental management plan to mitigate the potential

adverse environmental impacts during operation phase has been estimated as capital

cost Rs. 5 Lakhs and recurring expenditure as Rs. 9 Lakhs.

CORPORATE SOCIAL RESPONSIBILITY - Bharat Petroleum Corporation Limited

(BPCL) is a Public Sector Company. Therefore, Corporate Social Responsibility program

in the area is undertaken as per Government of India guidelines.


xiv

VII. CONCLUSION

Based on the environmental assessment, all possible environmental aspects have been

adequately assessed and necessary control measures have been formulated to meet

with statutory requirements, in the preparation of the EIA-EMP. The proposed

expansion in capacity is very much essential to meet the increasing demands in nearby

districts of Karur which consists of both rural and urban areas. Further, M/s. BPCL will

also meet the basic requirements of nearby villages like conducting health camps,

construction of basic facilities, drinking water supply etc. in the form of CSR activities.
