DRAFT EIA REPORT SUMMARY For Expansion of Dabolim Airport, Goa in Respect of Extension of Existing Integrated Terminal Building & Existing Apron at Dabolim Village, South Goa EIA District in Goa SUMMARY OF EIA PROJECT DESCRIPTION Goa Airport belongs to Ministry of Defence (Indian Navy) and Airports Authority of India (AAI) maintains an International Civil Enclave for facilitation of civil aircraft operation. Indian Navy provides air traffic services for the airport. Goa civil enclave is connected to several domestic and international destinations including all major cities in India like Mumbai, Bengaluru, Hyderabad, Chennai, Delhi, Srinagar, Kolkata, Pune, Patna, Ahmedabad, Cochin, Chandigarh, Indore and International destinations like Kuwait, Dubai, Sharjah, Doha, Muscat, Abu Dhabi, Kuala Lumpur, Moscow etc. The airport was built, in 1955, by the Government of the Estado da Índia Portuguesa, on 249 acres (101 ha) of land, as the Aeroporto de Dabolim, which was later officially renamed to Aeroporto General Bénard Guedes. Until 1961, the airport served as the main hub of the Portuguese India's airline TAIP (Transportes Aéreos da Índia Portuguesa). In April 1962, it was occupied by the Indian Navy's air wing when Major General K.P. Candeth, who had led the successful military operation into Goa, "handed over" the airport to the Indian Navy before relinquishing charge as its military governor to a Lieutenant Governor of the then Union Territory of Goa, Daman and Diu in June 1962. In 2006, the Indian Civil Aviation Ministry announced a plan to upgrade Dabolim Airport. This involved constructing a new international passenger terminal (after converting the existing one to domestic) and adding several more aircraft stands. The environmental clearance for the same was obtained on 15th March, 2008. To increase the handling capacity of runway, a parallel taxiway has been proposed to be constructed jointly by AAI and Indian Navy, for which Environmental Clearance was obtained on 3rd January, 2018. The present proposal is for extension of existing Integrated Terminal Building towards East by demolition of old Terminal Building, internal modification of existing Integrated Terminal Building and extension of existing Apron towards East to facilitate 3 no. code C Aircraft (AB-321/B739-900) parking.

The existing integrated terminal building which handles both domestic and international passengers is near saturated, therefore it is proposed to expand the existing integrated terminal building by demolishing the old terminal building to cater to the passengers’ convenience in future growth of Goa Airport. The airport is expected to handle 11.22 million passengers by 2020-21 and this may increase in the future. The proposal involves construction of 18,300m2 of centrally air conditioned as extension of existing integrated terminal building. The extended terminal building shall be capable of handling at least 3450 (domestic-2700 + international-750) passengers during peak hour. The proposal is also for expansion of existing Apron to the eastern side having an area of 15000 m2 to accommodate 3 numbers of AB- 321/B-737 type of aircrafts in power-in push out configuration space for Ground Support Equipments. ToR has been granted to Airports Authority of India, Goa proposal number IA/GA/MIS/73586/2018 dated on 15th May 2018 by Expert Appraisal Committee (EAC) and then applied for ToR Amendment as the area was mentioned as 35,500m² while after the engineering drawings were made, it was noted that area to be extended would by 18,300m² instead of 35,500m². The Amendment ToR has been granted to Airport Authority of India, Goa proposal number IA/GA/MIS/114951/2019 dated on 23rd September 2019. The site selected for proposed expansion lies within the existing airport premises. The site is located in Dabolim village, South Goa District. The site is approachable by NH-17 which is adjacent to the site in Northern direction. Dabolim Railway Station is located at a distance of 1 km in NE direction. Existing Features: The existing airport comprise of old and new terminal building, run way, apron, Parallel taxi track, taxy way, sewage treatment plant, multi-level car parking, fire station, fuel farm and other ancillary facilities etc. Proposed Features: It is proposed to expand the existing integrated terminal building by demolishing the old terminal building to cater to the passenger’s convenience in future growth of Goa Airport. The airport is expected to handle 11.22million passengers by 2020-22. The proposal also involves expansion of the existing Apron to the eastern side having an area of 15000m² to accommodate 3 nos AB-321/b-737 type of aircrafts. 1 Baggage handling system 2 Passenger boarding bridges 3 Flight information and displays Environment Consultant: PAGE Project Proponent: Greencindia Consulting Private Airports Authority of India Limited 2 DRAFT EIA REPORT SUMMARY For Expansion of Dabolim Airport, Goa in Respect of Extension of Existing Integrated Terminal Building & Existing Apron at Dabolim Village, South Goa EIA District in Goa 4 Sewage treatment facility 5 Fire fighting system 6 Security equipments 7 Book shop 8 Restaurant Land: The proposed project is a modernization/expansion project of domestic airport at Dabolim, Goa. Total land under AAI is 6.2 ha and expansion is planned in 1.83ha area for Terminal Building and 15000m2 for Apron. The entire land is under possession of AAI. Water Source and Demand: At present, Dabolim Airport at Goa requires 350KLD of fresh water which is sourced from PWD, Goa. After expansion, the fresh water requirement will be 700KLD which also will be sourced from PWD, Goa. During the construction stage, water will be sourced primarily through tankers arranged by the contractors as per specifications. Power Supply and Backup: The present power requirement of the airport is 3.5MVA which aster expansion will be 6MVA and is sourced from Goa Electricity Department.

It has been proposed that rainwater harvesting shall be done from roof top area of terminal building only. Total volume of rainwater available for RWH is 21.87 m³/hr. Manpower Requirement: The direct employment during construction phase in proposed project will be 200 skilled, unskilled and professional workforce including temporary and permanent employees shall be required. These workforces shall be hired locally in order to generate the employment to the local people. While during the project operation stage for the purposes of day-today professional and maintenance works about 1200 staff is existing in the airport which is sufficient for operation. DESCRIPTION OF ENVIRONMENT Topography: The project site more or less flat with elevation ranging from 44 - 47m amsl. The general slope is towards South. Seismology: The project site falls under seismic zone III which is a moderate damage risk zone. Soil • The soil is neutral to slightly alkaline, with pH ranging from 5.7 to 7.7 in the study area. The texture of the soil is dominantly sandy clay loam and clay loam in nature. • The moisture content of the soil samples is found to be low and ranges from 2.44% to 4.81%. This is due to low water holding capacity of the soil. • Organic carbon, a major nutrient for soil fertility, was ranged average (less to medium) in the study area. Overall, the NPK content was not found to be satisfactory for growth of plants. Therefore, it can be concluded that the soil quality in terms of fertility is not very good for growth of vegetation. Air: The Air Quality monitoring has been conducted for 7 sites in and around the project site. Particulate Matter (PM10& PM2.5): Maximum concentration of PM10 was recorded in AAQ1 (Project site- 76.1 μg/m3) while the minimum concentration was recorded in AAQ6, Mundvel (59.1 μg/m3). The higher concentration of PM10 in project site and some other locations may be attributed to high traffic density, construction activities in the vicinity and presence of commercial activities. PM2.5 ranges between 38.5 μg/m3 in project site (AAQ1) to 25.9 μg/m3 in BIT’s Pilani Campus (AAQ6).
