PRE-FEASIBILITY REPORT FOR

CONSTRUCTION OF PARALLEL TAXI TRACK AT DABOLIM AIRPORT, GOA

1.0 EXECUTIVE SUMMARY In order to meet the growing Air Traffic in Goa AAI, has constructed and commissioned New Integrated Terminal Building in March 2014 with peak hour capacity of 2750 Pax. (2000 Domestic and 750 International) having 5 Nos. Aerobridges. Presently, the parking of Aircraft capacity is 2 Nos. B category and 8 Nos. C category or 2 Nos. B category plus 5 Nos. C category and 2 Nos. D/E category. Dabolim Airport is a Naval Airport wherein the ATC is handled by Indian Navy. CNS facilities are also handled by Indian Navy. Airport Authority of India (AAI) handles Aircraft on Civil Apron, Terminal Building and City side facilities. Due to the absence of Parallel Taxi Track on the northern side of Runway 08 - 26, landed Aircraft has to backtrack on the runway to reach the Civil Apron using the Taxiways N1/N2, N4, N5 or using curtailed Parallel Taxi Track on the southern side involving crossing of runway. This process limits the runway capacity of handling Aircraft. With the present arrangement/procedure of Aircraft movement during takeoff and landing, due to the absence of Parallel Taxi Track on the northern side of the Runway, it has negative effect on the turnaround time of the Aircraft. The runway efficiency is also getting limited due to backtracking of Aircraft after landing using either Taxiway N4 & N5 or using southern side part Taxi Track involving crossing of runway. In order to reduce the runway occupancy time by Civil Flights, a full length parallel taxi track suitable for B747 type of Aircraft is required to be constructed. AAI and Indian Navy entered into a MOU for the same as AAI and Indian Navy to share the cost of construction 50:50. It is proposed to modify the existing layout to accommodate parallel taxiway and associated facilities to improve runway capacity and comfort of passengers. The schedule of project is envisaged as 30 months with an estimated cost of Rs.183 crores. There will be no addition of water requirement and generation of wastewater, solid waste after modification of layout.

2.0 INTRODUCTION Goa Airport at Dabolim is in existence since 1966 serving the civilian flights apart from meeting the defence requirements (Indian Navy). The Airport has seen gradual expansion in line with the Air Traffic Growth. The Apron capacity as well as Terminal capacity (Old) has been expanded in the past. In the year 2009, Apron capacity has been augmented to park total 10 Nos. Aircraft of C category. Dabolim Airport at Goa has seen phenomenal growth in the Air Traffic since 2007 which has been shown in the graphical form. Goa has the distinction of attracting foreign tourists who visit by Charter flights. In the year 2013-14, the number of Domestic passengers were 31,53,302 Nos., International passengers were 7,36,340 Nos., number of Domestic flights were 25,376 Nos., International flights were 4,420 Nos. and Chartered Flights were 1,141 Nos. In order to meet the growing Air Traffic in Goa AAI, has constructed and commissioned New Integrated Terminal Building in March 2014 with peak hour capacity of 2750 Pax. (2000 Domestic and 750 International) having 5Nos. Aerobridges. Presently, the parking of Aircraft capacity is 2Nos. B category and 8Nos. C category or 2Nos. B category plus 5Nos.

4.3 LAND FORM/TOPOGRAPHY/SOIL

The proposed project site is situated around 73049058.90o’ East longitude and 15o22o48.940’ North latitude. The study area is generally flat terrain. The general slope of the area from North-West to East -South. These are low-laying lands reclaimed from the sea around the coastal and river line stretches. Midland plateau sandwiched between the mountains and the coasts are plateaus of iron-rich red soil (leterite) that comprise the core of Goa’s topography. The soil cover is generally thin and cannot sustain forests. The main plateau vegetation is grasses, shrubs and wild flowers. However, low-laying areas like gullies and river basins have deeper soil and patches of monsoon forest occur there. The rivers transport a lot of rich fine soil from the highlands into the coast, forming very fertile alluvial lowlands. Major river-line plains are those of the Mandovi, Zuari, Chapora, Kushavati and Sal river. The approx. level of the area is 44.2 m above MSL. The topography of the study area is undulatory.

4.4 CLIMATE The climate of the region is characterised as tropical. The climate and wind pattern are governed by the annually monsoons and transition periods warmer towards interior and cools down in the hilly areas on account of elevation and vegetation. Only during the three monsoon months July, August and September the area experiences increased humidity, cloudiness and precipitation are observed. The year can broadly be divided into four seasons. The cold season starts from late November and extends to about the beginning of March. This is followed by the hot season which lasts till about middle of June when the monsoon arrives. The monsoon continues to the last week of September. The two post monsoon months October and November constitute a transition period from monsoon to winter conditions. Climatological normal data for the nearest station i.e. Panjim has been presented in Tables 12 -14. Rainfall & Humidity Climatological Normal Data on rainfall & humidity and cloudiness for the period 1951-1980 are presented in Table 12. The normal annual rainfall in the area is 2932.0 mm of which south-west monsoon accounts for the major part of the normal rain while North – East monsoon contributes around 25%. The air over the area is humid during the non-monsoon months and relative humidity is comparatively high. April and May are the hottest months of year with relative humidity of about 70.5% and 71.5% respectively. Other months, excepting May to October, it is practically rainless.

Micrometeorology The micrometeorological data generated during the study period are very useful for proper interpretation of the baseline information and it provides an input for prediction models for air quality dispersion. The transport and diffusion of the pollutants in the atmosphere are governed by meteorological factors. Factors like wind velocity, wind direction and atmospheric stability are known as primary/basic meteorological parameters since the dispersion and diffusion of pollutants depend mainly on these factors. Factors like ambient temperature, humidity, rainfall, atmospheric pressure, etc. are known as secondary meteorological parameters as these factors control the dispersion of the pollutants indirectly by affecting the primary factors. Thus, to assess the air pollution impact it becomes imperative to collect the above mentioned micrometeorological parameters in the project area.

4.5 SOCIAL INFRASTRUCTURE

As the Project site is located at a distance of about 10 km. from the heart of the Goa city, which is the capital of the state. All the amenities such as Hospitals, Schools, and Colleges etc. are naturally available. Medical facilities in the form of hospitals and dispensaries operated by the state government as well as private practitioners are adequate. Hospitals, PHC, and many private hospitals are present in the study area. Educational facilities available in the area are also adequate consist of engineering collages, medical & dental collages, degree collages, management collages and many more educational institution are present in Goa city. Thus, no impact on basic amenities is envisaged. Salient features of the basic amenities profile of the study area this presented in Table. 15.

10.0 BENEFITS OF PROJECT Due to the absence of Parallel Taxi Track on the northern side of Runway 08 - 26, landed Aircraft has to backtrack on the runway to reach the Civil Apron using the Taxiways N1/N2, N4, N5 or using curtailed Parallel Taxi Track on the southern side involving crossing of runway. This process limits the runway capacity of handling Aircraft. With the present arrangement/procedure of Aircraft movement during takeoff and landing, due to the absence of Parallel Taxi Track on the northern side of the Runway, it has negative effect on the turnaround time of the Aircraft. The runway efficiency is also getting limited due to backtracking of Aircraft after landing using either Taxiway N4 & N5 or using southern side part Taxi Track involving crossing of runway. Thus the proposed project will improve the runway capacity and comfort of passengers.
