M/s. Enerrgia Skyi Developers proposes developing a quality residential township “NEST” at Bhugaon in Pune, India by converting the existing land to an evergreen piece of environmentally friendly settlement without displacing any of the present population. The proposed scheme consists of 20 towers of 12 floors with parking and 38 town houses spanning a total plot area of 172,282 sq. m. including a green belt of 85,766 sq. m. It will support environmentally viable activities like rainwater harvesting, 35% energy conservation plans, recycling of waste water and debris, etc. Also, the project proponent proposes developing a green belt to maintain the existing bio-diversity and minimize the air pollution that may arise during the operational phase. Out of the total existing 196 trees, 24 would be transplanted and 3100 more would be planted to enhance the ecosystem of this region. EIA was conducted by Fine Envirotech Engineers on this project, taking into account the important environmental parameters. BES and impact assessments were conducted in the area of 10 km around the proposed site. Depending on the spatial relationship of various land use along the project road and wind direction, quality monitoring of major parameters were performed at 5 different locations. The average readings of all important parameters like air, water, noise, socio-economic, biodiversity, etc. were found to be within permissible values stipulated by CPCB. Mitigating measures, environmental management plans, disaster management plans, and risk assessments will be adopted and conducted suitably. Thus, based on EIA, this project is environmentally sustainable and with effective EMP and DMP; it would have a major positive impact in the area on the whole.

A complete assessment of the impacts caused due to widening of a National Highway on the air, water and soil environment in the nearest vicinity and 10 kms study area has been carried out and results presented. The Pune–Solapur National Highway-9 from km 144.00 to km 249.00 chainage has to be widened from existing 2 lane carriageway to 4/6 lane carriageway. The said project has been accorded Environmental Clearance from the Ministry of Environment and Forests (MoEF), Govt. of India, in the month of September 2011. The baseline study of the site comprising ambient air, noise, surface/ ground water, soil, landuse, ecological biodiversity and socio-economic factors of the area in 10 kms from the proposed widening site was carried out. Since the proposed project is a highway project, major air pollutants from the widening shall be vehicular exhaust emission from the increased traffic. This being a line source can be predicted through CALINE software. Study of ambient level of existing carbon monoxide (CO) concentration has been carried out in the EIA report. Predicted increased levels of air pollutant CO for worst-case scenario was projected based on the existing baseline data. The input parameters required for the CALINE software such as, traffic volume, meteorological parameters (wind speed, wind direction, stability class, mixing height), emission parameters, road geometry, terrain type, background pollutant concentration and receptor location are incorporated after carrying out site-specific study. The maximum concentration of Carbon Monoxide (CO) was found to be in the southwest direction of the proposed development. This ground level concentration of CO is very meagre and even after summing up with the existing ambient air level shall cause very negligible impact on the existing ambient air of the study area as assessed from the software results. Moreover, it is planned that vehicles plying in the area shall Air Pollution XX 47 doi:10.2495/AIR120051 www.witpress.com, ISSN 1743-3541 (on-line) WIT Transactions on Ecology and The Environment, Vol 1 , © 2012 WIT Press 57 be fitted with the EURO engines complying with the emission standards of India so as to reduce emissions during operational phase of the highway after widening. The detailed impact assessment as well as mitigation measures and the environmental management plan for the proposed project have been prepared.
