1 INTRODUCTION
Government of India in association with Government of Japan is developing a
Multi Model High Axle Load Dedicated Freight Corridor (DFC) between Delhi and
Mumbai, covering an overall length of 1483 km, with end terminals at Tughlakabad
and Dadri in the National Capital Region of Delhi and Jawaharlal Nehru Port at
Mumbai. This Dedicated Freight Corridor offers high-speed connectivity for High Axle
Load Wagons (25 Tonne) of Double Stacked Container Trains supported by high
power locomotives. The envisaged alignment of freight corridor passes through six
states viz. Uttar Pradesh, NCR of Delhi, Haryana, Rajasthan, Gujarat and
Maharashtra. The Delhi- Mumbai leg of the Golden Quadrilateral National Highway
also runs almost parallel to the Freight Corridor.
M/s Delhi Mumbai Industrial Corridor Development Corporation Limited
(DMICDC), was incorporated on 7th January, 2008, as the Project Development
Agency for Delhi Mumbai Industrial Corridor (DMIC). The Government of India holds
49% equity in M/s DMICDC. DMICDC acts as a facilitator for the development of all
basic infrastructure in investment regions / industrial areas/ economic regions/
industrial nodes and townships in the region including roads, ports, freight corridor,
power and airports.
M/s DMICDC Ltd. had been suggested three potential sites by Energy
Department, Government of Gujarat and Gujarat Infrastructure Development Board
(GIDB) for establishment of the proposed gas based power project. Thereafter a
joint team with representatives from DMICDC Energy Department, GoG and GIDB
visited the potential sites and collected information for assessing the suitability of the
sites. Based on the above information and site selection criteria, the site near to
Vaghel village, in Sami taluka of Patan District, was found to be suitable for
development of the proposed gas based power project.
M/s DMICDC Vaghel Power Company Limited Ltd. A dedicated project SPV
has been incorporated by M/s DMICDC Ltd. to develop the proposed 1300 MW Gas
based power plant at Vaghel village, Sami Taluka in the Patan District of Gujarat
State.
M/s Detox Corporation Private Ltd., (Detox), a QCI/ NBRT (Quality Council of
India) accredited environmental consulting agency has been entrusted to undertake
this EIA study. Subsequently, Detox has carried out baseline environmental studies
Detox
Executive summary for DMICDC Vaghel Power Company Limited 4
during the summer 2010 and developed this Environmental Impact Assessment
(EIA) report as per the guidelines and best practices suggested by Ministry of
Environment and Forests (MoEF).
The project was placed before the Expert Appraisal Committee of Ministry of
Environment & Forests (MoEF) for approval of ToR for the EIA study. The project
received the approval for carryout EIA study from MoEF and the copy of Terms of
Reference approval letter issued by MoEF is placed at annexure-1 of EIA report.
2 NEED OF PROJECT
The proposed high-speed connectivity between Delhi and Mumbai offers
immense opportunities for development of an Industrial corridor along the alignment
of the connecting infrastructure. A band of 150 km to 200km (Influence region) has
been chosen on both sides of the Dedicated Freight corridor to be developed as the
Delhi-Mumbai Industrial Corridor. This corridor will be equipped with an array of
infrastructure facilities such as power facilities, rail connectivity etc. Several
industrial estates and clusters, industrial hubs, with top-of-the-line infrastructure
would be developed along this corridor to attract more foreign investment.
In order to support these developments in the Delhi Mumbai Industrial Corridor
(DMIC) region and to attract investors (global and domestic); it is essential to supply
reliable and uninterrupted power. Given the current and projected peak load demand
and using the indexation of electricity ratio of electricity to industrial growth rate
anticipated in the plan, the peak power demand for the DMIC region is expected to
reach 27,200 MW by year 2013-14 and rise up to 71,000 MW by 2039. The proposed
power project would be able to meet partial power requirement of the upcoming
industries in the DMIC region.

7.3 WATER ENVIRONMENT
Baseline data
The existing water quality of surface and ground water in the study area was
evaluated. Samples were collected from the surface water (village ponds) in the
nearby region around 10 Km radius of the project site. Ground water samples from
the existing bore wells were collected. Total 6 nos. of sample for ground water and 9
nos. of sample for surface water were evaluated.
Ground water
To evaluate the ground water quality in the study area six bore wells were selected
from nearby villages of the project site. From the analytical results it was found out
that TDS level near the project locality is very high; except at one well location in
Vaghel village having TDS value of 240mg/L, which is due to its location in close
proximity to the large village pond and there is possible recharge from this well.
TDS level from other wells are varying from 1410 mg/L to 4188 mg/L. with the
highest at one well sampled in Aritha village, which is clearly indicating high saline
ground water in this region . The chloride level, and Conductivity are also supporting
the high saline ground water conditions in the study area, which were found to be
varies between 851 mg/L to 2269 mg/L and 3280µS/ to9740 µS respectively, but at
the well located at Vaghel village Chloride content and conductivity level was found
to be only 56.72 mg/L and 560 µS due to the recharge from the large village pond.
Fluoride content was found out at all the wells, sampled except one at Aritha village.
The fluoride level was varying from 0.72-1.07 mg/. Mercury level in all the sampled
wells was below the detectable limit.
Surface water
In order to evaluate the surface water quality of the study area, nine village ponds
were sampled. The surface water quality of these rain water fed ponds are of good
quality water with the TDS level varying from 86-680 mg/L, with maximum at one
pond in Harij village. The total alkalinity varies from 140 mg/l to 380 mg/l with
maximum at Harij village. Chloride level was varying from 16.07 – 284 mg/L with
maximum at Harij. Sulphate content was detected only in two ponds sampled.
Detox
Executive summary for DMICDC Vaghel Power Company Limited 15
Nitrate content of the pond at harij was slightly higher with 33.82 mg/L. which may
be due to the agricultural runoff or other anthropogenic activities in/from the
surrounding areas of this pond. The analytical result indicates the availability of good
quality surface water in this region.
The detail water balance diagram for the project showing the water consumption in
various plant activities and waste water generation from the project is as given in
Figure below.
7.4 Waste water Generated
Effluents from the main plant drains, oily waste, etc. would be treated in the local
treatment facilities provided within the respective plants and recycled wherever
possible. Oily waste would be treated using oil separator/skimmer. Oil separator
would be designed for treating the run-off water in the oil facility area during
rainstorm. Clear water would be led to sump.

Impact study with mitigation measures
It has been estimated that about 8424 m3/day of wastewater will be generated from
the proposed power plant and about 80 M3/ day STP treated water from colony and
plant premises. 80 m3/day STP treated waste water would be utilized for plantation
and green belt in the plant/ colony area. An attempt was being made to explore the
possibility of recycling and reuse of the excess wastewater generated by RO
treatment. In this way about 5054 m3/Day can be recycled back to the system. Only
about 3370 m3/day RO reject has to be reused in green belt and landscape
development. Blow down from Cooling tower System can also be used as makeup to
Plant service water and as well as makeup supply to Fire water storage tanks. Excess
CW blow down water shall be led to the Guard pond. Provision shall be made for
diverting complete Cooling tower blow down water to the Central Guard pond which
can be recycled or reused after RO treatment. Blow down drain from HRSG/Power
Detox
Executive summary for DMICDC Vaghel Power Company Limited 17
Cycle, and other Condensate drains etc. which are relatively of pure quality shall be
collected in central guard pond and shall be reused or recycled on continuous basis.
Total land available for the project is about 226 Acres. About 101.56 Acre land
demarcated for greenbelt development and landscape within the plant premises.
Rainwater Harvesting
Geologically the area study area comprises of Alluvium soil. It comprises of
alternate beds of sand, clay and Kankar. It has been proposed to adopt Rainwater
Harvesting system in the proposed project by adopting storm water collection and
reuse program during monsoon period. Rainwater harvesting structure shall be
provided to recharge the groundwater resources in the region. During monsoon
period, the runoff water from the roof of the structure and paved areas shall be
collected through storm water drainage system and initially led to underground raw-
water storage and surplus water in the rain water harvesting structure. With an
average monthly rainfall of about 128.8 mm/month (~12.8 mm/day with 10 rainy
days) during peak monsoon period, it has been estimated that about 6000 to 10000
m3/day of runoff would be generated from the project. With a raw-water reservoir
capacity of 2, 39,568 m3, significant quantities of run-off from the plant site can be
stored and reused for plant cooling applications. Several recharge well will be located
at strategic locations within the plant and will be interconnected to the storm water
drain network system. This will ensure the recharging of the ground water table. The
ground water table at the project site is 5.3 m and as the site is closely located
Narmada Canal Command Area. As per the hydro-geological information available for
the project site, the ground water in and around the study area is mainly confined in
unconfined and semi confined conditions.
7.5 NOISE ENVIRONMENT
Baseline data
The noise generation at the site and in the surrounding areas was mainly due to
vehicular transportations and normal village activities. Due to crop cutting season in
nearby field and new road making activities the noise level was slightly higher in
some locations; however all these activities are of temporary in nature.
Detox
Executive summary for DMICDC Vaghel Power Company Limited 18
Impact study
During the construction phase the major noise generation will be from the
mechanical equipment installed at site for the construction work and noise due to
vehicular movement.
During operation phase the major noise generation will be from the mechanical
equipments at the plant site mainly gas engine and compressors.
Mitigation measures

8 GREEN BELT DEVELOPMENT
In order to reduce the pollutant dispersion in the atmosphere, to resist the noise
generated due to plant activity and to uptake the wastewater generated to some
extent, it is recommended to develop green belt around the periphery of the plant
road side area. The total green belt area proposed to be developed is about 101.56
acres which is about 45 % of the total plot area. It is proposed to develop green belt
of about 50 meter width, consisting of three tiers of trees species, around the project
boundary with a tree density not less than 2500 tress per hectare. It also entrusted
to maintain at least 75 % survival rate. In addition to development of green belt
within the premises the company is committed to carry out afforestation and
biodiversity improvement programme in the surrounding villages.
