Raichur: Members of the district unit of the Karnataka Rakshana Vedike took out a procession and staged a dharna here on Wednesday in protest against the establishment of super-critical thermal plants at Yermarus and Yedlapur villages near Raichur. The activists led by Ashok Kumar, president of the district unit of the vedike, went in a procession from Netaji Circle to the Deputy Commissioner's office and staged a silent dharna. Mr. Kumar, who submitted a memorandum to the authorities, said the existing Raichur Thermal Power Station at Shakthinagar had continuously threatened the environment by way of pollution from its coal and fly-ash. Despite this, the State Government had implemented the super-critical thermal power stations at Yermarus and Yedlapur villages near Raichur against the interests of the public.The new thermal plants, with an installed capacity of 2,400 MW, might pose additional environmental problems such as pollution of Krishna water and fertile land along the banks of the river. The people and several social organisations had expressed their opposition to such projects, but unfortunately Karnataka Power Corporation Ltd. had gone ahead with the work.
