1.0 INTRODUCTION

Existing Rajkot airport spreads over 250 acres and has a single runway 05/23 suitable for
operation of B737 type aircraft. Presently A320 type of aircraft is operating with load penalty.
The airport is surrounded by a railway line and a state highway on the eastern side and
residential development all around the airport. Since the existing runway length cannot be
extended, the chances for operating wide bodied aircrafts from the current facility is ruled out.
The main approach road to the airport passes through densely populated residential zones and
is narrow and congested.

Rajkot Urban Development Authority and Rajkot Municipal Corporation had proposed a plan to
extend Rajkot airport runway from current 5,400 feet (1,600 m) to 6,000 feet (1,800 m) to
accommodate larger aircrafts so as to provide better connectivity to major cities besides
Mumbai and to cater to a large demand from the manufacturing companies located in Rajkot.
The Airports Authority of India (AAI) and Ministry of Civil Aviation (MOCA) could not negotiate
land acquisition price with Western Railways, thereby nullifying the only possibility of expansion
of existing airport. Thus, Govt of Gujarat intends for the construction of an altogether new
Greenfield Airport for the city of Rajkot.

As per AAI traffic forecast, all airports in Gujarat have a moderate air-traffic growth of 5-8% with
exceptions of Ahmedabad and Vadodara where traffic growth is between 8-10 %. The holistic
development of Hirasar airport shall not only serve the demand generated by the city Rajkot
but also, cater to the demand created on account of development in the neighbouring states.
Over a due course of time, the airport shall also meet the spillover needs to Ahmedabad.

Continued robust growth in the region and broader Indian economy are expected to be the
primary drivers of domestic air travel at Rajkot. Also, the historical and architecturally rich
cultural heritage of Gujarat and of the surrounding regions attracts international visitors
throughout the year. To aid the development of trade and tourism and improve regional
connectivity Gujarat needs additional aviation infrastructure. Considering the factor and the
potential growth around the city, the airport is anticipated to have a considerable increase in air
traffic. Owing to this, state government of Gujarat is desirous to develop a new green field
international airport at Rajkot.

Ministry of Environment and Forest & Climate change (MoEF & CC) has approved terms of
reference (TOR) for EIA study wide letter no. 10-12/2017.IA.III dated 7th June 2017.
Accordingly Govt. of Gujarat has entrusted the task of carrying out EIA to Engineers India
Limited (EIL) as per approved TOR.

The proposed site is accessible from State highway no.8A i.e. Ahmedabad- Rajkot state
highway. An area of 1025.5 ha acres is envisaged for project development. The expected cost
of the project in phase 1 excluding airport city is INR 1405 crores.

The components in phase I includes Proposed Airport Size of Single Runway of Length 3040 m
x Width (45 m), Single Runway for operation of C category aircrafts, Two number of parallel
taxi tracks, Separation distance as per C category Aircrafts, Apron Layout, Rapid Exist Taxi
Track, Development of Passenger Terminal Building, Cargo Terminal Building, MRO/Hangars,
Six lane approach road to airport and boundary for new airport, Utilities and other
miscellaneous facilities are envisaged.

A study area of 10 km radius around the proposed airport at Hirasar village is considered for
assessment and evaluation of impacts on various components of environment during both

construction and operational phases of the project. M/s Pragati Laboratories Private Limited
(PLPL), an NABL Accredited Lab collected environmental baseline data in terms of various
parameters during the period April to June 2017.

2.0 BASELINE ENVIRONMENT

It can be seen fromt the above that within project site also wastelands occupy predominant
land use. Administratively the proposed site falls within Doshalighuna (46.9%), Garida (29.8%),
Hirasar (20.4%), Loma Kotadi (2.3%), and Bamanbore (0.7%).
Meteorology– The temperature varied between 27 – 44oC in the months of April to June 2017.
The predominant wind directions were west, south west, west south west and south-south
west.

Air environment: Ambient air quality was monitored at 8 locations. 98 Percentile concentrations
of PM ranged from 54.7 to 62.5 µg/m3 and for and PM ranged from 24.7 to 32.7 µg/m3
10 2.5
respectively. The concentrations of SO & NOx were in the range of 10.8 – 14.7 µg/m3, and
2
12.3 – 18.8 µg/m3, respectively. The concentrations of PM & PM , SO , NOx, CO are found
10 2.5 2
to be well within the NAAQS limits.

Noise environment: Noise levels were monitored at 6 locations. Noise levels ranged between
48.5 – 69.0 dB (A) during day time and 39.9 – 58.9 dB (A) during night time and the levels were
found to be well within limits.

Land environment: Waste lands is the predominant land use in the study area. Soil samples
were collected from 8 locations. The pH values ranged from 6.94 – 8.07, indicating moderate
alkaline property. The nitrogen content present in the soil samples is sufficient. The soil
samples for all locations are low to high in range of phosphorous. The potassium values in soil
samples for all locations are mostly high.
.
Water environment: Three surface and four ground water samples were collected. In the
ground water samples, pH, total dissolved solids, hardness, chlorides and sulphates ranged
from 7.2 -7.5, 210 - 2348 mg/l, 128-450 mg/l, 36 - 930 mg/l and 25 - 350 mg/l respectively. At
all locations these were within the permissible limits as per IS: 10500.

Biological environment: A total of 203 plant species, 74 birds, 32 butterflies, 6 amphibians, 16
reptiles and 12 mammals are identified and enumerated in the surrounding areas. There are no
National Park and Wildlife Sanctuary present in the 10 km radius from the proposed Rajkot
airport.

Socio-economic conditions: As per Census data (2011), study area of 10 km radius comprises
of 30 villages with a total population of 47039. The perception of project affected persons is
conditionally favourable for the proposed project as they are reluctant to relocate to an
alternate land without same amount of agricultural and gauchar land for their cattle and
provision of employment opportunities, and better public infrastructure facilities.

The work of acquisition of Private land is given to Gujarat Industrial Development of
Corporation by the Industries and Mines Government of Gujarat. For that, administrative
approval is given to allocate of Rs. 10 Crore to the GIDC. The Government of Gujarat will
suitably consider rehabilitation and resettlement if some families are to be relocated
