Without stricter checks, directive to ‘utilise’ fly ash may prove futile

Joseph B. Hash

The hottest federal government try to be certain the secure and sustainable disposal of fly ash–a poisonous residue remaining about from burning coal–could conclusion up harming India’s farmlands, water bodies and fragile habitats, say scientists and activists. Fly ash is recognized to induce air and water pollution.

Coal and lignite-primarily based thermal energy plants should “be certain 100% utilisation of ash generated by it in an eco-welcoming fashion”, explained an April 22, 2021 notification of the Ministry of Ecosystem, Forest and Local weather Improve (MoEFCC).

About the final two decades, the Indian federal government has been issuing very similar notifications on the disposal and utilisation of fly ash. Its recommendations have diverse: use it to manufacture building substance and in design work use it as soil conditioner in farms and use it to reclaim low-lying parts and empty mines. Nonetheless, about 50% of industries continue to be non-compliant, typically dumping the ash in the open, in water bodies and in unlined and uncovered pits.

There have been eight important incidents involving coal ash in India concerning August 2019 and May 2021, as for every a standing report by Fly Ash Watch Group, a collective of activist men and women and organisations throughout India. The Singrauli region unfold throughout Singrauli district in Madhya Pradesh and Sonbhadra district in Uttar Pradesh accounted for fifty percent of these.

In 2019-twenty, 197 thermal plants in India generated 226 million tonnes of fly ash. And virtually one.six billion tonnes of it are scattered about 65,000 acres of land, as of 2019.

Accidents take place typically when fly ash overflows or breaks by the embankment of ash ponds wherever it has been dumped. An ash pond is made with an embankment all close to and an inside and external drainage system. It wants to be constantly monitored for protection and spillage.

Environmentalists have been urging the federal government to delete “filling of low lying location” as an acknowledged use of fly ash. “There are no apparent recommendations on what constitutes a ‘low-lying area’,” explained Rahul Choudhary, Supreme Court docket advocate and founding member of the Authorized Initiative for Forest and Ecosystem (Daily life). Even riverine stretches and wetlands can be thought of low-lying, he pointed out.

Little action has been taken towards erring units, as we depth afterwards. We achieved out to the MoEFCC for feedback on fly ash mismanagement. This posting will be up-to-date as and when we obtain a response.

Coal-primarily based energy plants are amongst the most polluting industries in India, significantly liable for its dire air pollution stages, research have demonstrated. Coal-primarily based thermal energy plants are water intense, employing additional water than permitted, IndiaSpend has described in September 2019.

Policies diluted about the a long time

About 76 fly ash accidents have been described in mainstream English media in the final ten years, killing persons and thoroughly harming water sources, air and soil, explained a joint 2020 review by the Healthful Electricity Initiative and Community Environmental Monitoring, a thoroughly clean power advocacy. Madhya Pradesh, Odisha, Tamil Nadu and West Bengal have the optimum selection of coal-primarily based thermal energy plants and report the most fly ash accidents, according to the review.

Fly ash spillage is tough to resolve and polluters and authorities have demonstrated no fascination in cleansing up, observed industry experts. “The moment water is contaminated there is no undoing [the contamination], but even for the obvious places of ash spillage there is no thoroughly clean-up carried out by plant authorities,” explained Shripad Dharmadhikary, analyst at the exploration organisation Manthan Adhyayan Kendra, who also co-authored the Fly Ash Watch report. “The eight important incidents [August 2019 – May 2021] you should not consider into account the ash spill that transpires routinely.”

The federal government has been making an attempt to deal with the problem due to the fact 1999.

The 1st formal notification on the subject arrived in 1999 and it outlined some techniques for the constructive use of fly ash–to manufacture cement, concrete blocks and bricks and in the design of roadways and embankments within a 100-km radius of thermal energy plants.

Nonetheless, subsequent notifications–in 2003, 2009, 2014, 2016, 2019, 2020 and the hottest, in 2021–diluted the definition of and deadline for ash utilisation by polluters. They allowed the reclamation of low-lying parts and abandoned mines employing ash, prolonged deadlines for polluters, raised the distance about which fly ash can be transported and did away with the ash content material cap in coal.

In 2019-twenty, the energy sector consumed 678 million tons of coal and generated 226 million tonnes of ash. Of this, only 187 million tonnes (eighty two%) was put to use in a variety of approaches. The remaining squander piled up, harming the natural environment.

The Centre for Science and Ecosystem analysed condition smart-info on ash technology and utilisation concerning 2010 and 2019 and observed Chhattisgarh and Uttar Pradesh had gathered the most ash throughout this period. And Madhya Pradesh, Andhra Pradesh, Maharashtra and Odisha have large ash backlogs. In buy to minimise this pollution, urgent actions are desired, explained industry experts.

On the draft notification, the Manthan Adhyayan Kendra commented that it “seems to prioritise total disposal of fly ash with out satisfactory things to consider of the protection of well being and natural environment”. The assume-tank Centre for Plan Investigation also pointed out the have to have to consider into account “non-compliance induced breaches of ash dykes and ponds and existing preventive and restitutive actions for the exact”. Apart from authorized troubles, it pointed to “serious impacts this kind of as contamination of farmlands, prevalent use parts, water bodies and air, for a long time”.

Periodic disasters, no action

“In the final two decades due to the fact the notification was 1st released, the problem of fly ash has escalated. The subsequent notifications have allowed violations which have led to fly ash breach accidents and the regulatory authorities are clueless on how to cope with it,” explained Shweta Narayan, an environmental justice activist and campaigner for local climate and well being with Health Care Devoid of Damage in India.

In June 2021, a fly ash breach accident was described in Chattisgarh’s Korba thermal energy plant, explained Savita Rath, a neighborhood activist and attorney. “Only three plants–Jindal’s Raigarh energy plant, Korba West plant and DB energy plant–have ponds to dispose of ash. So several other plants in Chhattisgarh you should not have any system in location. And, even in these ponds, ash is piled up like small hills. Is there no limit to how much one particular can accumulate in the ponds?”

Earlier, in April 2020, the wall of the Reliance Thermal Plant’s ash pond in Singrauli district of Madhya Pradesh collapsed claiming at least two lives, destroying agricultural land and contaminating groundwater. The Singrauli region houses ten thermal energy plants. It is a chosen industrial area mainly because it gives quick accessibility to coal and water from the nearby Rihand reservoir. In the final two a long time alone, four of the eight important ash pond breach incidents took location in the region.

“About 6 months just before the collapse of the [ash pond] wall, neighborhood villagers and gram panchayat associates had protested and warned that the wall of the pond could collapse whenever,” explained Sandeep Sahu, a neighborhood activist, on the Reliance Plant accident. “This was [the consequence of] very long-phrase negligence.” The district collector’s office had also warned plant officials about the precariousness of the ash dyke but no action was taken, explained a Newsclick report.

Truant units undeterred by strictures

Given that 2013, Supreme Court docket advocate and environmentalist Ashwani Kumar Dubey has submitted quite a few petitions in the National Environmentally friendly Tribunal (NGT) on fly ash disposal in the Rihand reservoir. All the thermal plants in the region are positioned on the banking institutions of the reservoir, he instructed IndiaSpend. “The reservoir is the only supply of drinking water for the persons of Singrauli and Sonbhadra districts and the total water overall body has been contaminated, producing it unfit for intake,” Dubey explained. In quite a few instances, the NGT has reprimanded plant authorities but that does not surface to work as a deterrent.

The North Chennai Thermal Electricity Plant is a circumstance in place. The litigation on ash slurry leaks has been likely on for a long time. In 2017, the NGT had warned the plant of overall closure if it failed to include the discharge. In January 2020, the tribunal even imposed a penalty of Rs 8.34 crore. Irrespective of this, the pollution continues.

Fly ash transportation is also harmful. India exports substantial portions of fly ash to Bangladesh, wherever it is used to make cement and it is transported by the Sundarbans by barges. 5 incidents of capsizing of this kind of barges occurred in 2020, according to the reply to a Right-to-Information and facts request submitted by the Manthan Adhyayan Kendra.

“That contains the unfold of pollutants is additional difficult in the water and when mixed with hefty rains or cyclones, it is dispersed to a for a longer time and wider stretch of the water bodies,” Avli Verma, an analyst at the Manthan Adhyayan Kendra, instructed IndiaSpend. There are no research in the general public domain to evaluate the injury brought about by fly ash to water bodies in a variety of accidents.

We achieved out to the Inland Waterways Authority of India on irrespective of whether any injury assessment is carried out when fly ash barrages capsize. We will update when we obtain a response.

Considered non-harmful squander

In 2000, the ministry reclassified fly ash as strong squander from “harmful industrial squander”, and put it in the exact group as residence squander. As strong squander, fly ash is subject to various and significantly a lot less stringent restrictions on how it should be managed in contrast to harmful squander, explained Narayan of Health Care Devoid of Damage.

Given that 2009, the Skilled Appraisal Committee–which assesses the environmental effects of a job for the MoEFCC–has been directing plant authorities to not dispose of ash in low-lying parts in their natural environment clearance circumstances (see right here, right here and right here). Nonetheless, the 2019 office memorandum by the ministry deleted this condition with retrospective result.

In the circumstance of Neyveli Uttar Pradesh Electricity Ltd Plant in Ghatampur, Kanpur Nagar, the natural environment clearance directed the plant authorities to put in location mechanisms for the constant checking of radioactivity and hefty metals in fly ash.

“None of the orders have been complied [with]. The condition businesses are also in denial method,” explained SC advocate Dubey. He approached the Supreme Court docket on non-compliance in the Rihand reservoir circumstance, but the make a difference is pending mainly because of the ongoing pandemic.

The NGT has been imposing penalties on erring plants in quite a few instances but it does not element in the ongoing contamination and the injury this causes to the lives and livelihoods of these residing in the vicinity and to its very long-phrase ecological effects, Choudhary explained.

Fears about greater coal production

About the a long time, with an enhance in energy technology, India has been looking at an enhance in coal ash technology. As the total of fly ash greater, the natural environment ministry introduced in, as we explained, quite a few notifications and amendments to the notifications aiming to accomplish 100% utilisation of fly ash within a specified deadline.

“Utilisation targets are difficult to accomplish,” explained Dharmadhikary of the Manthan Adhyayan Kendra. Legacy ash–unused about a long time–and the freshly generated ash piles up in ash ponds or open fields. Devoid of satisfactory authorized action towards violators and weak compliance, breaches will go on undeterred, explained activists.

With the opening up of the coal sector for commercial mining by personal players in 2018, and with reduced oversight, there will be even further enhance in ash technology, it is feared.
