A rally and a public meeting were held here on Monday to protest against the Centre's plan to construct a dam at Tipaimukh at the trijunction of Manipur, Mizoram and Assam. The Action Committee Against the Tipaimukh Dam (ACATD), formed by 25 civil organisations, organised the protest on the eve of the opening of global tenders by the North-Eastern Electric Power Corporation (NEEPCO). It was alleged that the NEEPCO had not obtained forest and environmental clearance for the Rs. 10,000-crore dam. At a public hearing in Mizoram, the people opposed the project. However, no such session was held in Manipur. A NEEPCO official told reporters that a hearing would soon be conducted in Manipur. As all sections are against the project, the Government proposes to deploy three battalions of security forces to give protection to dam officials and workers.
