47. Description Of Environment Study area includes places of historical importance such as: The Elephanta Caves. Karnala Bird Sanctuary. Matheran Eco-sensitive Zone. 4/27/2011 27
48. Project Activites Project area s about 2054 Ha. Airport zone is about 1615 Ha. Consisting of 1200 Ha. For aeronautical activity and 415 Ha. For non- aeronautical activity. Remaining area is there for utility services. 4/27/2011 28
49. Project activities involves: Development of Airport in four phases Training of Gadhi river Diversion of Ulve river Shifting of EHT Lines Development of off-airport site (non-aeronautical area) Approach roads, railways, interchanges, water transport service to airport zone in the vicinity and far Re-settlement and Rehabilitation Development of various Utilities in the airport zone 4/27/2011 29
50.
51. sewage treatment plant based on the SBR technology will treat aeronautical area will have 15 MLD capacity and non-aeronautical area 30 MLD installed capacity.
52. The solid waste generated to the tune of 10 tones/day initially and finally 40 tones/day will be treated at plant at Chaal, Taloja.
55. Positive Impacts Project will facilitate the fast movement of man and materials, thereby fostering trade and commerce. support employment generation, CM outlined that around 1lakh direct jobs and around 4lakh indirect jobs due to this project. Pressure on other airport at Santacruz will be eased. offer increased accessibility, which in turn fuels the tourism sector which causes more money flows into the local economy. raising the standard of living of the people in the region. provides a thrust to the GDP of the local region, having a positively impact on the national economy. it will handle 60 million passengers/year which is much smaller than the international standard of 100 million passengers/year so there is always possibilities of expansion. 4/27/2011 32
57. Impacts due to NMIA Location Removal of Mangroves & Biodiversity: With the project intervention, A total of 161.50 ha of mangroves (though in degraded form) will be lost due to the project. Tree clearance: There is no forest in the project site area, though there are naturally growing trees/plants/vegetation in the area. This project will result in loss of all vegetation in the project site. Roads and infrastruture: two impacts namely the over concretizationand diversion of agricultural land leading to issues of land use change and food security. Though the surface soil is being stripped off for brick making. Water ways connectivity: stress on the surrounding marine ecosystem and fishing. Rehabilitation: Ten settlements approx 15000 people will be affected due to the project. 4/27/2011 34
58. Impacts due to NMIA Project Design Training of Gadhi River: Channelization leads to altering of original dimensions of the rivers along with extreme physical disturbances, alterations in river bed morphology, change in flow characteristics and elimination of bank cover. The impacts of channelization on the aquatic community mainly arise due to channel excavation, dredging, clearing and removal of vegetation. Siltation affects aquatic vegetation by increasing the turbidity of water. loss and reduction in the number of organisms. Diversion of Ulwe River: he impacts of diversion is similar to that ‘ Training of Gadhi river” 4/27/2011 35
60. Hill Cutting (Quarrying / Blasting): Generation of heavy quantity of dust which raises the SPM levels in the vicinity. noise levels also will increase occasionally. Reclamation of marshy lands: the rise in the water levels will be slightly over 1.5 m river training would take place on existing land cover. studies indicate marginal rise in the water levels in the Panvel creek reach along the proposed airport boundary. 4/27/2011 37
61. Impact Due To Construction Phase Employment, Migration and Settlement: stress in the area surrounding the project in terms of water requirement, power, increased ecological footprint, increased requirement for health and educational facilities and changes in the land use pattern and local culture. Siting of construction camp for construction: stress on the local ecological resources Leveling of site: leveling process would lead to an intense / heavy quantity of dust which would raises the SPM levels in the vicinity. the noise levels would be high due to the machinery used for leveling. Safety of Workers Construction Activity 4/27/2011 38
63. Impacts during Operation Phase of NMIA Operation of airport: two major impacts include that of air emissions and noise. Surface Traffic: air quality is affected Noise also is affected Employment, Migration & Settlement: 4/27/2011 40
66. Air sector Appropriate dust suppression measures will be implemented within the project site. Use of asbestos will be prohibited. Background air quality of all transport corridors will be maintained by reducing idling time and control on emissions. Aerobridges would be used for passenger transportation 4/27/2011 43
67. Biodiversity and Forests CIDCO has planned to take up approx 350 Ha. of plantation of mangroves against the 161.50 Ha. Loss. The channelization activities are designed to keep flow characteristics as close to the original natural flow. compensatory vegetation and plantation programme will be undertaken within the airport area contamination of estuarine body would occur mostly during the construction phase due to resuspension of sediments or dust from construction site, both of which are temporary. There was no wildlife, observed during the field survey. 4/27/2011 44
68. Ecosystem and Land Impact of dredging and channelization can be reduced by proper routing of alignment to maintain a proper flow. The proposed project activity does not involve clearing of any forest areas The proposed site and the study area do not include any migratory route of animals. he excavated material/construction debris would be used for land development of marshy land in the project site area. The project area lies in Deccan trap composed of hard massive basalt rock and will not initiate any instability problems – landslide/subsidence etc The predicted water levels at different locations with and without the proposed airport are practically same. And as stated earlier STP and landfill sites are available in near by area to treat waste generated from the airport. 4/27/2011 45
69. Disaster management plan Natural Disasters: earthquake flood storms/cyclone cloud burst/lightning/extreme weather conditions Fire Terror Attack, Plane Hijack, Sabotage A highly equiped airport is developed to counter all the calamities and disasters. Aircraft Accident Related Disasters: aircraft accident at airport aircraft accident off airport Hazardous material emergency, hydrocarbon spills (ATF) followed by vapour dispersion and pool fire fire 4/27/2011 46
70. Conclusion The project is necessary and should be given a nod. Development is necessary, but development along with environment is acceptable. So adopt sustainable development. Human imagination is touching sky, sky is part of environment so better preserve for imagination hence future. Go green. 4/27/2011 47
