high (4.5 x 10- 4 to 6.3 x 10- 6 cm/sec) Executive Summary Page No 6(9) settlements in the region. (iii) The fresh water is available below 30 - 40 m bgl. Site IV (Old Bawana Site) Area available is 60 Hectares (i) The site is under protected Forest land. (ii) The site is within groundwater recharge zone by western Yamuna canal. Also it has shallow groundwater table. (i) The site has sufficient land area for developing a landfill facility for more than 20 years. (iii) The site is about 500m from Bawana - Narela road. Permeability of the soil is comparatively high ( 5.1 to 32.4 x 10 -7 cm/sec). Based on the ranking of MOEF as well as internationally followed criteria, Site III located near village Guman Hera is proposed for development of SLF for disposal of hazardous waste. The environmental impacts of developing and operating the SLF at the proposed site near village Guman Hera were assessed. In order to mitigate the adverse environmental impacts, mitigation measures have been proposed. Accordingly, Environmental Management Plan (EMP) has been prepared which shall be followed at the sites for disposal of hazardous waste in environmentally sound manner. The mitigation measures to be taken are summarised in the following action points: - Κ Κ Κ Κ Provide Protective Gears (such as Full sleeve apron, gumboots, mask, Gloves etc) to workers Training to workers for safe handling of wastes. Leachate collection, treatment and disposal (systematic collection and treatment of the leachate generated in the landfill facility). Periodic Environmental Quality monitoring for ground water and ambient air around site. Environment Division, National Productivity Council, New Delhi
Κ Κ Executive Summary Page No 7(9) Green belt development surrounding the facility in order to abate air & noise pollution and to reduce the storm water drainage. Periodic water spray in order to suppress dust while carrying out excavation and construction activities After implementation of proposed EMP and mitigation measures, the disposal of hazardous waste at the recommended site shall be considered as environmentally sound process as it will take care of the following: • Ground water and soil protection through the provisions of an impermeable base of the facility, lined drain and disposal of non compatible waste in different cells. • Surface water protection through diversion of surface run-on and installation of leachate treatment plant. The Environmental Impact Statement for the site at Guman Hera is as given below: 1. The total area of the site is reported to be 56 hectares (140 acres). However, the area required for developing SLF for 20 years is only 26.35 hectares. The land has been acquired by Municipal Corporation of Delhi, Govt. of NCT - Delhi. 2. The site lies in the salt affected area with scattered shrub grass vegetation, amidst patches of brick Kiln relics and small temporary water pools. The site falls in structural sag zone. It is located in wastelands within a dominantly agricultural landuse. 3. There is no human population within 1 km distance of the site. The nearest village is Guman Hera, which is 1 km away. The site is adjacent to a "Gaushala" (Cow shelter). However, there is no regular use by inhabitants in the Gaushala. 4. The nearest surface water body is Najafgarh drain, which is about 500 m away from the site. 5. The groundwater table is available at 4.5 m b.g.l. The base of the landfill should be atleast 2 m above the groundwater table. So a Double Composite Liner system is proposed to be installed at the bottom of the landfill to prevent the percolation of leachate to the ground water. The quality of water at this level is however, saline. The fresh water aquifer in this area is available at a depth beyond 35 m bgl. 6. As reported, the proposed site does not fall under any notified forest. 7. There is no navigable river or stream within the 100 m distance of the site. 8. As reported, the proposed site does not fall under flood prone area of the Yamuna River. Therefore, developing the secured landfill facility at the proposed site is not having the risk of flood.
