Chennai: Seeking to assert Tamil Nadu's rights over Mullaperiyar dam, Chief Minister Jayalalithaa on Sunday said a special Assembly session would be convened on December five to pass a resolution that the state will not give up rights over it due to 'imaginary threats' on its safety and security.

"A special Assembly session will be convened on December 15 at 11 AM to pass a resolution that this state will not give up our rights over Mullaperiyar because of the imaginary threat to the safety and security of the dam," she said in a statement.

Jayalalithaa said her government believed the "solution to this problem lies in presenting sound technical and scientific data to the Supreme Court and convincing it about the justness of our stand."

"With regard to the present issue, neither my people nor I and my government have got anything against the people of Kerala or their government. We have no quarrel with the people of Kerala."

"Therefore, destroying their (Keralites' in Tamil Nadu) property or causing injury to them and in the process also causing ourselves pain and hardship is not a solution," she said.

Urging the public to allow the government to handle the issue scientifically and logically and not get carried away emotionally, Jayalalithaa asked people of border areas not to precipitate the situation and to disperse immmediately.

The two states have been at loggerheads over the issue for long.

Tamil Nadu, which receives water from the dam in Kerala's Idukki district for irrigation in its southern districts, is opposed to any move to decommission the 116-year-old structure, saying it is safe.

The Kerala Assembly had on Dec 9 unanimously adopted a resolution to build a new dam to replace the reservoir and lowering the water level to 120 feet in the existing structure over which the state and Tamil Nadu are locked in a dispute.

Jayalalithaa had on December 4 written to Prime Minister Manmohan Singh to order deployment of CISF at Mullaperiyar dam site "to avoid any man made catastrophic consequences" in view of violent activities reported there.

"In view of violent activities reported at the dam site, it is imperative that Central forces be deployed at the dam immediately. I therefore, request you to order deployment of Central Industrial Security Force at the site to avert any man made catastrophic consequences immediately", she had said in the letter.

Security tightened near TN, Kerala border

Tension over the Mullaperiyar dam issue mounted in the border town of Kumili and adjoining areas as marchers from Tamil Nadu side threatened to cross into the state, prompting police to further tighten security.

Road to Theni area in Tamil Nadu remained closed and a large police contingent, including Rapid Action Force personnel, had been deployed to prevent the marchers from crossing over and brewing trouble.

On Tamil Nadu side, police blocked roads to check marchers from pushing to Kerala. Senior police officials from both sides were in constant touch with each other to keep the situation tightly under control.

Inspector General of Police R Sreelekha, who was here to review the situation, said additonal forces were deployed in the area on Sunday.

Vigil also heightened in alternate routes, by-lanes and forest trekking paths as well in view of the possibility of protesters filtering in through them, police sources said.

Kumali town, which has an array of curio and spices shops normally busy with tourists coming to the close by lake-side resort Thekkady on the banks of the river Periyar, wore a deserted look. Police asked shops to down shutters and put up metal barricades across the road and sealed the border check post, halting to and fro traffic totally.

Police said so far no untoward incident had been reported from any part of the area, where prohibitory orders have been in force since early last week.

Opposition leader and CPI(M) stalwart V S Achuthanandan wanted all national parties to formulate their stand on the dam issue by taking into account the spirit of the unanimous resolution passed by Kerala Assembly last week, which called for a new dam and lowering the water level in the existing reservoir to 120 feet.

Talking to reporters in Palakkad, Achuthanandan said he would join Chief Minister Oommen Chandy to meet Prime Minister Manmohan Sing to press for the state's demand.
