Towards achieving the objective of remediation of legacy landfill sites in a time-bound manner, the Centre has approved projects worth Rs 776 crore to remediate 253 lakh metric tonnes of waste spanning 186 acres of land across Delhi, officials said on Monday. A high-level meeting was held on Monday by the Union Ministry of Housing and Urban Affairs (MoHUA) to discuss the progress made in the remediation of the three legacy dumpsites in areas -- Okhla, Ghazipur and Bhalswa -- under the three municipal corporations in Delhi. The meeting, chaired by the MoHUA secretary, was attended by senior officials of various ministries and organisations, Delhi Development Authority vice chairman, commissioners of all three corporations, representatives from Central Pollution Control Board, National Thermal Power Corporation, and National Highways Authority of India, the ministry said in a statement. The issue of legacy dumpsites across cities in India is a source of continuing environmental concern. The Swachh Bharat Mission-Urban (2.0) or SBM-U 2.0, being implemented by MoHUA, has taken up the challenge in a targeted manner, in a first of its kind initiative in the country.
