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


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.

3 COST OF PROJECT

Total capital investment for the proposed power plant project is approximately Rs.

3800 Crores.

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


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


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


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

Noise generating equipment shall be place in enclosed area equipped with silencers.

The operators working in the high-noise areas shall be strictly instructed to use ear-

muffs/ear-plugs.

Green belt shall be developed to attenuate noise and the extent of green belt shall

be as per CPCB guidelines.

Training of personnel is recommended to create awareness about the damaging

effects of vibrations; if PPEs are not used as regular practice while on duty.

Regular noise monitoring on weekly basis will be carried out at the noise generating

sources and the entry - exit gates of the plant.

7.6 FLORA AND FAUNA

No threatened flora and fauna observed in the study area.

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.

15 CONCLUSIONS

After carrying out the Environment Impact Assessment studies, it has been

concluded that by adopting a robust environmental management plan and risk

mitigation measures as presented in the EIA report, the proposed project would

exhibit very insignificant environmental impacts. However, the implementation of

proposed massive plantation, green belt area and community development programs

under CSR activities would bring significant positive impacts to the entire region.
