The problem of disposal of hazardous wastes generated by industrial activities is being studied by environmentalists, planners, policy makers. This paper showcases the land use/ land cover analysis of a part of the National Capital Region, India, which was carried out in order to analyse the feasibility of a suitable site for hazardous waste in the NCR
The problems of disposal of hazardous wastes generated by industrial activities is being studied by the environmentalists, planners, policy and decision makers. The issue of its disposal/dumping poses serious challenge to the civic authorities and has worried the planners, as it threatened the social and environmental settings.
In Delhi, a secured landfill site was identified at Bawana for disposal of hazardous waste generated. However, this site could not be developed into landfill due to public opposition. In absence of any secured landfill site most of the hazardous waste at present finds place in municipal waste dumpsites and pose environmental hazard. A site for developing ‘common hazardous waste treatment and disposal facility (CHWTDF)’ should therefore be identified and developed without delay so that scientific disposal of hazardous waste can be initiated. In order to identify possible sites for development of common hazardous waste treatment and disposal facility for disposal of hazardous waste generated in Delhi in the NCR, discussions were held with concerned officials of state pollution control boards in UP and Haryana at district as well as capital HQ levels. During the discussions with concerned officers following points emerged:
- In Ghaziabad/Noida area, Government of UP has identified land of around 16 acres to be developed as common hazardous waste disposal site for waste generated from Ghaziabad – Noida region
- In Faridabad/Gurgaon area, Government of Haryana has identified a piece of land of around 32 acres near Village Pali on Gurgaon – Faridabad Road to be developed as common hazardous waste disposal site for waste generated from entire Haryana State.
For the purpose of ranking the various sites identified for disposal of hazardous waste in the region, a ranking criteria published by Ministry of Environment and Forests (MoEF) in 1991 addressing Management and Handling of Hazardous Wastes for (a) generators, (b) transport of hazardous waste, and (c) owners/operators of hazardous waste storage, treatment and disposal facility. The guidelines provide attribute given in Table 1 below. For each of these attributes, a four-level sensitivity scale has been considered ranging from 0 (indicating no potential hazard) to 1 (indicating highest potential hazard).
In this ranking the site with the least score is less sensitive, i.e. there will not be significant impact on environmental quality due to locating hazardous waste treatment and disposal facility on this site.
In addition, Central Pollution Control Board (CPCB) has also developed locational criteria for siting hazardous waste landfills as follows
No landfill shall be constructed
- Within 200 m of any lake or pond
- Within 100 m of navigable river or stream
- Within 500 m of the right of way on highway
- Within critical habitat areas including reserved forest
- Within wetlands
- Within a zone around airport as notified by regulatory authority or airport authority
- In a coastal regulatory zone and
- In areas where groundwater is less than 2 m below the base of the landfill
