Stream of ash

Residents of Bikuthanda tribal village in Andhra Pradesh’s Khammam district are a worried lot. The village’s only water stream, which was till recently their primary source of drinking water, has turned grey because of polluting industries nearby. Residents say water from the Bhoodidavagu stream, which means stream of ash, causes itching and skin diseases. ‘We are scared of even touching the water. Cattle have died after drinking water from this stream,’ says 40-year-old resident Sona B.
Bikuthanda is one of the villages in the Paloncha block that falls under the integrated tribal development programme that was created to develop the tribes in the area. But in reality, Paloncha, along with neighbouring Kothagudem block, is home to highly polluting industries, including the Kothagudem thermal power station (KTPS), Nava Bharat Ferro Alloys, Sponge Iron India Limited and the coal mines of the National Mineral Development Corporation. The projects are affecting residents in 27 villages, including Bikuthanda.

Waste water and fly ash from the coal-based KTPS, located three kilometres from Bikuthanda, has contaminated the Bhoodidavagu stream. The 12 chimneys of the station emit thick black smoke day and night, and the plant discharges effluents directly into the water body, say the residents.
The contamination of the stream has forced the residents to dig bore wells. ‘But most of them are dry because water level has gone down by 100-120 metres,’ says K Ramulu, sarpanch of Somalagudem grama panchayat, which has nine villages including Bikuthanda. Residents also say the quality of groundwater has deteriorated because of stream contamination. The condition of Suranam, another affected village in Paloncha, is worse. The village, which is hardly 500 metres from the ash pond of the plant, is always under a thick cover of fly ash. ‘We can’t grow anything,’ says J Lakshmamma, a 60-year-old tribal woman suffering from severe asthma and skin allergies. Her husband J Veeranna is a chronic bronchitis patient. ‘Please help us,’ they plead with folded hands.

KTPS is one of the six coal-based thermal power plants owned by the Andhra Pradesh Power Generation Corporation, the third largest power generation utility in the country. KTPS was started in July 1966 with 60 MW installed capacity. Within one year, the installed capacity was increased four times. At present, the station has 11 units operating with a total installed capacity of 1,720 MW. Eight of the units are 36 to 48 years old, and are highly inefficient and polluting.

‘The authorities went on adding capacity without doing anything to control pollution,’ says Ramesh Rathode of Green Earth Society, a non-profit in Paloncha. Officials at the state pollution control board’s (PCB) regional office in Kothagudem, 10 km from the thermal station, confirm high levels of air and water pollution. ‘The level of suspended particulate matter emission should not exceed 150 milligram per normal cubic metre (mg/Nm3). However, our random inspections of KTPS units have revealed that suspended particulate matter level at times has gone up to 1,000 mg/Nm3,’ says M Narayana, environmental engineer, PCB. ‘KTPS is using inferior quality coal with 50-60 per cent ash content. The facilities were designed for coal with ash content up to 35 per cent,’ says Narayana.

PCB issued over 10 show-cause notices to KTPS between 2007 and 2014 for violating provisions of the Water (Prevention and Control of Pollution) Act 1974 and the Air (Prevention and Control of Pollution) Act 1981. It has also issued specific directions to the company to take time-bound actions to comply with the regulations. The last notice was sent in January this year.

In a notice to KTPS in 2008, the PCB observed that the industry was letting out the ash slurry into Karakavagu, a fresh water stream (Bhoodidavagu is a part of Karakavagu). The stream, after getting contaminated, merges with the Kinnersani river, a major tributary of the Godavari.

The river passes through the Kinnersani Wildlife Sanctuary before joining the Godavari. The water stream, from Bhoodidavagu to Godavari, is getting polluted due to the direct discharge of ash slurry by KTPS. Ideally, the ash slurry should be safely disposed in an ash pond.
