2 1. PROJECT BACKGROUND Airports play a significant role in globalization, connecting cities and countries. Airports are a major part of a country s infrastructure and foster economic activities by encouraging international commerce and tourism and generating employment. Arunachal Pradesh is the largest state in the North Eastern region and is without any airport. So far Naharlagun, which is about 15 km from Itanagar, is connected by helicopter service. The state capital of Itanagar is, therefore, neither connected to other states by air and nor by rail. For better connectivity and overall development of the state, the Government of Arunachal Pradesh has decided to place the state capital i.e. Itanagar on the country s map in respect of airports by constructing a new airport at Itanagar. Five sites namely Nirjuli, Gumto, Imchi, Banderdeva and Holongi were examined for setting up the airport. After examining all the sites, Holongi site was found suitable because of the following topographical/geo-graphical and operational advantages: Approach and take off area is free from natural obstacle; Involvement of lesser earthwork; Less development cost in comparison to earlier site of Banderdeva; Possibility of all weather operation by A-321 class of aircraft; The faster accessibility through existing NH-52 A from Itanagar; and Least interference to airspace of existing operational airports in the vicinity. In addition to construction of airport, it has been decided that the project will include provision for commercial activities such as hotel and a convention center at the airport. 1.1 Project Proponent Airports Authority of India (AAI) was constituted by an Act of Parliament and came into being on 1st April Currently, it manages a total of 125 Airports, which include 11 International Airports, 08 Customs Airports, 81 Domestic Airports and 25 Civil Enclaves at Defence Airfields. AAI also provides Air Traffic Management Services (ATMS) over entire Indian Air Space and adjoining oceanic areas with ground installations at all Airports and 25 other locations to ensure safety of Aircraft operations. 2. PROJECT DESCRIPTION 2.1 Type of Aircraft The proposed project is a green field airport project which involves construction of a new runway, a new terminal building and other aviation facilities including provision for commercial activities such as hotel, convention center etc. 2.2 Location 33

3 The proposed site is located in village Holongi, Baliajan tehsil, Papum Pare district, Arunachal Pradesh. The site lies between Kokila and Holongi water streams and is approachable from NH-52A. The proposed site falls in Survey of India Toposheet No. 83 E/12, 83 E/16, 83 F/19 and 83 F/13. The location map and 10 km radius study area map are given in Figure-1 and Figure-2 respectively.

Distance from Itanagar 25 Km in east direction 20 Km in the South west direction Both sites connected by NH 52A 3. Topography Terrain Hilly terrain, for setting up of the airport, heavy cutting as high as 50m and filling as deep as 40 m approx involved. Heavy river training work involved for diversion of two streams from site and need to pass through box culvert under the proposed runway. Plain area, minimum cutting filling involved, in fact only filling is involved for 1-2 m height. Two streams are passing at the ends of proposed runway; hence Heavy river training work may not be required. 4. Accessibility New approach road is required from NH52 A to reach the proposed site. Approach road to site is already available, only need to be widen. 5. Level difference between runway/airport site and main road Airport site would be about 20 m above general terrain level. Airport elevation: 190m Airport site would be practically on same level as connecting NH 52A. Airport elevation: 100m 6 Instrument approach procedures Need to be assessed in view of the obstacles around the airport. Instrument approach possible for both ends of proposed runway. 7 Runway Orientation 08/26 08/26 (true bearing 078/258 degrees) 8 Airport elevation 190 m Approx. 100 m Approx. 35

Power Requirement 40

10 Power required for the entire airport would be 1000 KW by construction of independent 33 KV line upto airport as suggested by State Government. 2.6 Waste water Generation & management The wastewater generation mainly consists of sanitary waste, sewage from airport terminal, flight kitchen, effluent from the workshop etc. The sewage and sanitary waste from the buildings and airport terminal will be treated in Sewage Treatment Plant (STP) comprising primary, secondary and tertiary treatment facilities. The treated wastewater from the STP will be used for air conditioning, cooling water make-up and green belt development. It is estimated that about 72 KLD of wastewater will be generated from the proposed airport. The entire wastewater that is generated from the airport will be recycled and reused for non potable purposes. 2.7 Solid Waste Management 3. SITE ANALYSIS Solid waste generated from the proposed airport mainly comprises of food waste and garbage waste. Further, small quantities of sludge from STP, medical waste and other waste will be generated. Collection and handling of domestic solid waste would be done in line with the provisions of the Municipal Solid Waste Rules 2000 (as amended). 3.1 Connectivity The proposed site at Holongi is located approximately at a distance of 20 Km in South West of NH-52 A. The proposed site measuring 320 hectares approximately is mainly a plain land and lies between two rivers i.e. Kokila and Holongi. The site lies in the foothills. It s size is approx 3.00 KM in length and 1.30 KM width, adjacent to NH-52A near Holongi Check post. 3.2 Land form, Land use & Land ownership The airport is proposed on Hectares land out of which at present 320 Hectares land will be developed for proposed airport and is being acquired by State Government. State Government is additionally acquired another Hectares for R&R. A brief about the findings & analysis of the proposed site is mentioned below: Operations of the aircraft: As per the initial assessment of the Holongi site, the approach funnel of both the runway 08 and 26 are clear of natural terrain and instrument approaches are possible for both the runways. 41

11 3.2.2 Safety Issues: Rescue operations will be easier, in the approach and take off path. The Airport proposed on the flat land, will be less prone to earthquake disasters Construction Issues: The site being the flat land, it will be easier to develop the airport. The site is easily approachable by NH-52 and NH-52A. The site will require filling of 2 to 3 m (approx.), earth can be made available from the nearby foothills Future Expansion: Expansion will be easier, if so desired, the land required for future extensions/expansion may be acquired in the beginning itself Land Issues: The site reported to be mostly private land, but other version as mentioned earlier also, the land forms the part of Drupong reserved forest and part of which has been notified for the established of the Chakma refugees. It was reported that land acquisition is likely to pose following difficulties: - Rehabilitation & Resettlement of Chakmas - Acquisition of land - Issue of cost of land Chakmas being a sensitive issue, the State Government is to give consideration for the resettlement of Chakmas refugees. 3.3 Topography The proposed site is almost flat cultivable land. The site is inhabitated by a few Kachha hut settlement. It was informed that the Chakma refugees have been settled in this area and these huts belong to them. The other version was that this land forms the part of Drupong Reserved Forests, part of which (under consideration for the Airport) has been notified for the settlement of Chakma refugees. However, the land required for the airport, needs acquisition by the State Govt. as per the existing provisions. The level of Holongi site is below the NH-52A level by 2 to 3 m and will require earthfilling. The water streams at both the sides would require to be trained. Approach path of proposed runway are clear of obstacles except the HT lines. In the northern side, there is a chain of hills which may form obstacles in the transition surface and need to be addressed. The HT power lines, observed in the approach path of the proposed runway, will need shifting. 42

12 3.4 Proposed Land use pattern The site proposed for Airport development is along the National Highway 52A. The runway orientation is angled to the longitudinal length of the site thus dividing the site into two distinct areas. The area towards the NH 52A is the area being considered for the development of the airport Operational Land Use The runway orientation being the deciding factor, the land along the runway is to be maintained as essentially required as mandated by ICAO. The same applies to the land along the approach funnels. Maintaining mandated distances for an apron/ taxi way and apron parking for Code C aircraft, the location of the passenger terminal building is to be planned. The terminal building is, therefore, proposed towards hill side on the proposed approach road to NH 52A Terminal Complex & Other Facilities It is proposed to construct Main Terminal Building, ATC cum Technical Block, Fire Station, Sub-station and other Ancillary buildings for the optimum utilization of the land in phases Commercial Land Use There is proposal to construct hotels and convention centre near to the Main Road, NH- 52A, for convenience to the passengers and other users by State Govt Residential Land Use A residential complex for the essential operational and other staff is also proposed within the airport boundary. The site being flat, various types of houses like Type A, B, C & D are proposed for officers and staff as per their entitlement. 3.5 Existing Infrastructure Presently, the site is devoid of any infrastructure, except few settlements, and transmission lines. 3.6 Social Infrastructure Available The existing social infrastructure in the Itanagar which is located at about 15 km from the site is: Hospital with ambulance; 43

13 Banks; Post office; Bus station; Fire station; Secondary school; Police station; Shopping complex; Sports infrastructure (Stadium & Camps etc); Community halls; Cinema halls; and Primary health care centres. 4. REHABILITATION & RESETTLEMENT About 156 families would be affected due to the proposed project. Tentatively, Rs. 36 Crores is being allocated for the rehabilitation of 156 chakma families from the proposed project. 5.
