Under attack on the issue of waste management, Delhi's Lieutenant Governor today told the Supreme Court that he was regularly monitoring the situation and efforts were on to tackle the problem of "legacy mounds" at three landfill sites of the national capital in a comprehensive, safe and scientific manner.
The top court sought a report of experts and environmentalist on reducing the gigantic mounds of garbage at the sites at Ghazipur, Bhalswa and Okhla.
The court had last week castigated the LG over his attitude of being "a superman" but doing nothing to get the "mountains of garbage" of the city cleared, with one of the dumping sites even reaching a height close to that of the Qutub Minar.
In an affidavit filed on his behalf, Lt Gov Anil Baijal said "Immediately after assuming office on December 31, 2016, the LG visited the Bhalswa landfill site in January 2017, Okhla landfill site in February 2017, Ghazipur landfill site in later part of the year".
Additional Solicitor General Pinky Anand, appearing for LG's Office, said he had also visited Construction and Demolition Waste Plants (C&D Waste) at Burari in February 2017 and Shastri Park in July 2017 and December 2017.
"He directed all three (municipal) corporations to augment capacities of Waste-to-Energy plants for scientific disposal of current waste to reduce waste disposal at landfill sites and simultaneously take measures to tackle the problem of legacy mounds in a comprehensive, safe and scientific manner," Anand said.
She said that Delhi currently faced major issues with respect to waste management, including "management of legacy mounds and processing of daily waste generated".

"A scientific advisory committee comprising high level experts from premier institute of IITs, CSIR and TERI was set up on September 22, 2017 to manage the 34 million metric tonnes of garbage in the form of legacy mounds at the three landfill sites by adoption of scientfic methods," Anand said.
She said the committee has highlighted various problems in managing these mounds, including that the height at all the three sites was excessive, there were steep slopes, accumulation of waste and occurence of internal and external fires along the slopes of the landfills at Bhalswa and Ghazipur.
"There was high production of methane inside the landfills. Attempts to douse these fires by conventional fire fighting techniques (using fire brigades) have not been successful," she said.
Anand said that by acting on the advice of project team of IIT, till July 2018, about 30 to 40 per cent of short-term slope stabilisation has been achieved at the Okhla site.
The bench, after perusing the photographs of the work done at the landfill sites, expressed unhappiness and said that it seems that mud has been splattered all around.
Anand said that work was being done as per the recommendation of the scientific advisory committee as this was the only viable and feasible solution. "We have only this solution looking at the challenges of shortage of land, landfill sites and daily waste accumulation," she said.
The bench said that as per records of the LG office, the garbage mound at Ghazipur had come down from 55 to 45 metres, but "what will happen to the plastic beneath 45 metres. Are you going to drill it 45 meters and then take it out. This can't be the solution."
