NMMC - Environmental Status Report 2003 -2004 10 Roads and Transport 10.1 Present Status National Highway 4 (NH-4) passes through the NMMC area. Navi Mumbai is connected by road and rail to Thane, Kalyan, Mumbai, JNPT, Uran and Panvel. The work of Thane-Belapur railway is in progress, the construction of railway stations is complete and rail link shall be commissioned soon. Navi Mumbai is close to Sahara International and Chhatrapati Shivaji domestic airport. A new airport is planned in Navi Mumbai. There is a network of roads about 327 km in length in NMMC area. (Table 10.1.1). There are footpaths and pathways along major roads. Total length of footpaths and walkways is over 47.24 km. (Table 10.1.2). Navi Mumbai has six rail corridors, 157 km railway system and an independent mainline rail terminal connecting the city directly to other parts of the country. Vashi, Sanpada, Juinagar, Nerul and Belapur in Navi Mumbai are on Harbour line of the central railway. Plan to develop a domestic airport i n Navi Mumbai is in the offering. The proposed trans-harbor link between Mumbai and Navi Mumbai is further expected to enhance the status of this city by forming yet another link with Mumbai.

NMMC has its own bus service. In addition the buses of BEST and Maharashtra State Road Transport Corporation ply through Navi Mumbai. NMMC Transport undertaking has 176 buses catering to 44,50,009 per month (Table 10.1.3). There are over 6.41 lakh vehicles registered in Thane district of which NMMC area forms part for vehicle registration (Table 10.1.4). This has resulted in traffic problems in cert ain areas. NMMC has undertaken programme for improvement of internal roads to reduce the problem by providing additional lane for left turn, creating turning lane, parking space and signalised traffic to decongest the traffic movement. However, the major concern in traffic is increasing number of road accidents and deaths due to accidents.

Foot paths are important since they are used by pedestrians which form the large cross- section of the society. Besides well maintained foot paths relieve traffic congestion problem on the road surface area thereby minimizing vehicular emission which is mainly responsible for deterioration of air quality. After handing over the area to NMMC, maintenance, repairs as well as providing additional foot paths is entrusted to NMMC. The details are in Table 10.1.6. It can be seen that construction of additional footpaths at Koparkhairne and Airoli area has been planned. Including providing slopes to the footpath for creating access to physically challanged persons. Whereas for other areas expenditure that proposed to be incurred is mainly required for repairs, maintenance and improvement. It would be seen that for Nerul area cost of maintenance and repairs is on the higher side mainly because of work of laying optical fibre cable and other utility services is under taken.

A chemical species foreign to the clean atmosphere is called a contaminant. A contaminant that can cause adverse effect to the receptor (human being, animals, vegetation etc) and which occurs in atmosphere in concentrations sufficiently high to cause the adverse effect is called a pollutant. Air quality is negatively affected by emissions from mobile and point sources; these are directly linked to energy consumption, environmental policy, city density, and transport by motor vehicles and concentration of industries. The main environmental problems associated with air emissions are harm to human health (eye irritation, pulmonary problems, etc) problems, the acidification and eutrophication of water and soils, and damage to natural ecosystems, cultural heritage and crops. Often these are transboundary effects, as pollutants in the air can travel a considerable distance away from their sources. In addition, emissions from sources in urban areas can have a significant local impact on human health. In India, standards have been stipulated by the Ministry of Environment and Forests under Environment Protection Act 1986 for both sources of pollution (emission) and ambient air quality. Industries are required to meet their obligations of controlling pollution under Air (Prevention and Control of Pollution) Act, 1981. Motor Vehicles Rules 1989 require vehicles to comply with emission norms and obtain pollution under control certificate. Results of air quality monitoring carried out during May-June 2004 (Table 10.2.1) reveal that air pollutant levels in residential areas in NMMC are within the standards for respirable suspended particulate matter (RSPM), sulphur dioxide (SO2) and nitrogen dioxide (NOx). However, values of suspended particulate matter and carbon monoxide are above standards. This is mainly due to traffic pollution. This is further confirmed by the monitoring carried out at the traffic junctions (Table 10.2.2). Concentrations of RSPM, SO2 and NOx were found alarming. 52 NMMC - Environmental Status Report 2003 -2004 Table 10.2.1: Ambient Air Quality in NMMC Area 3 3 Location RSPM TSPM SO 2 mg/m NOx mg/m CO mg/m 3 mg/m 3 mg/m 3 CBD Belapur 54 202 10.3 22.7 5.2 Nerul 64 194 11.5 21.5 4.7 Vashi 60 179 11.0 22.8 4.9 Turbhe 86 230 13.3 28.5 6.1 Koparkhairne Dumpin ground 83 250 18.3 18.5 4.8 Ghansoli 74 196 13.7 21.4 4.7 Airoli 65 240 13.2 28.6 4.5 Digha 65 219 17.6 30.6 6.2 Standards 100 200 80 80 4.0 Note: All standards are for 24 hours except for CO, which is for 1 hour.

Two types of indices have been used to assess air quality in NMMC area. First air quality index AQI1 based on total suspended matter, sulphur dioxide, and nitrogen. The second AQI2 is based on respirable particulate matter, sulphur dioxide and nitrogen dioxide reveals that air quality is fair (AQI 49-53).
