Rapid EIA Studies of 3 Pre-identified Hazardous Waste Disposal Sites in NCT - Delhi: No.15 (c) Flood Plain: Page No landfill shall be constructed within a 100-year flood plain. A landfill may be built within the flood plains of secondary streams if an embankment is built along the stream side to avoid flooding of the area. However, landfills must not be built within the flood plains of major rivers unless properly designed protection embankments are constructed around the landfills. (d) Highway: No landfill shall be constructed within 500 m of the "right-of-way" of any state or national highway. (e) Habitation: A landfill site shall be at least 500 m from a notified habitate area. A zone of 500 m around a landfill boundary should be declared a no-development buffer zone after the landfill location is finalized. (f) Public parks: No landfill shall be constructed within 500 m of a public park. (g) Critical Habitat Area: No landfill shall be constructed within critical habitat areas including reserved forest areas. A critical habitat area is defined as the area in which one or more endangered species live. It is sometimes difficult to identify a critical habitat area. If there is any doubt then the DPCC shall be consulted for clarification. (h) Wetlands: No landfill shall be constructed within wetlands. It is often difficult to identify a wetland area. Maps may be available for some wetlands, but in many cases such maps are absent or are incorrect. If there is any doubt, then the DPCC shall be consulted for clarification. (i) Airports: No landfill shall be constructed within a zone around Airports as notified by the regulatory authority or the aviation authority. (J) Water Supply Well: No landfill shall be constructed within 500 m of any water supply well. (j) Coastal Regulation Zone: No landfill shall be sited in a coastal regulation zone. (k) Ground water table: No landfill shall be located in areas where the ground water table will be less than 2 m below the base of the landfill. 3.2.3 Site Selection Hazardous waste landfills should preferably be located in areas of low population density, low alternative land use value, low ground water contamination potential and at sites having high clay content in the subsoil.

Rapid EIA Studies of 3 Pre-identified Hazardous Waste Disposal Sites in NCT - Delhi: Page No.16 A HW landfill will be selected following the guidelines published by MOEF. The step by step procedure will be as follows: (i) (ii) Earmarking a 'search area' taking 'into account the location of the waste generation units and a 'search radius' (typically 5 to 250 km). The search area will be so chosen that it minimises the number of HW landfills in any region or state. Identification of a list of potential sites on the basis of: (a) (b) availability of land collection of preliminary data (c) restrictions listed in the locational criteria (section 3.2.2). (iii) Collection of preliminary data as follows: (a) (b) (c) (d) (e) (f) (g) (h) (i) Topographic Maps: A topographic map will help find sites that are not on natural surface water drains or flood plains. Topographical maps may be procured from Survey of India. Soil Maps: These maps, primarily meant for agricultural use, will show the types of soil near the surface. They are of limited use as they do not show types of soil a few meter below the surface. They may be procured from Indian Agricultural Research Institute. Land Use Plans: These plans are useful in delineating areas with definite zoning restrictions. There may be restrictions on the use of agricultural land or on the use of forest land for landfill purposes. Such maps are available with the Town Planning Authority or the Municipality. Transportation Maps: These maps, which indicate roads and railways and locations of airports, are used to determine the transportation needs in developing a site. Water Use Plans: Such maps are usually not readily available. A plan indicating the following items should be developed: private and public tubewells indicating the capacity of each well, major and minor drinking water supply line(s), water intake wells located on surface water bodies, and open wells. Flood Plain Maps: These maps are used to delineate areas that are within a 100 year flood plain. Landfill siting must be avoided within the flood plains of major rivers. Geologic Maps: These maps will indicate geologic features and bedrock levels. A general idea about soil type can be developed from a geological map. Such maps can be procured from Geological Survey of India. , Aerial Photographs / Satellite Imagery: Aerial photographs or satellite imageries may not exist for the entire search area. However such information may prove to be extremely helpful. Surface features such as small lakes, intermittent stream beds and current land use, which may not have been identified in earlier map searches, can be easily identified using aerial photographs. Ground Water Maps: Ground water contour maps are available in various regions which indicate the depth to ground water below the land surface as well as regional ground water flow patterns. Such maps should be collected from Ground water Boards or Minor Irrigation Tubewell Corporations, (j) Rainfall Data The monthly rainfall data for the region should be collected from the Indian Meteorological Department.
