Chandigarh/Shimla: The one-day northern zone chief ministers' conference will be held here tomorrow amidst tight security. The Chief Ministers of six northern states and the UT Administrator will participate in the conference that will begin with Union Home Minister P Chidambaram's address at 10 am. The conference will aim at boosting regional cooperation and iron out differences between the states. Hotel Mountview, the conference venue, has been sanitised. The teams of dignitaries that started arriving this morning have been put up in areas that have been cordoned off. According to Punjab Chief Minister Parkash Singh Badal, the northern states will discuss issues pertaining to inter-state problems and raise their demands before the Union Home Minister. Punjab has come out with a coloured booklet highlighting achievements of the SAD-BJP government in fields like infrastructure, industry, environment, power projects, education, health care, etc. Haryana is also preparing an agenda that was yet to be finalised till the filing of this report. It is expected that the state will raise the issue of water sharing between the two riparian states. Chief Ministers of Himachal Pradesh, Punjab, Haryana, Delhi, Rajasthan and Jammu and Kashmir will represent their states, while Chandigarh will be represented by Administrator Shivraj Patil. The event is out of bounds for all, except the chief ministers and official delegations accompanying them. The media is expected to be briefed about the deliberations at a meeting in the afternoon. Badal said Punjab had taken the initiative to host the conference and hoped such conference would be held regularly in future. The last such conference, he said, was held in 2005. Punjab is expected to raise the issue of water sharing with Haryana. Hansi Butana Canal and flow of water from the Ghaggar are expected to be raised by both Punjab and Haryana. Punjab is also likely to take up with the Union Home Minister the issue of posting of officers in Chandigarh in a 60:40 ratio as per the original agreement. Since the UT Administrator will represent Chandigarh in the conference, the three states could reach some agreement. Himachal Pradesh has been demanding a cess on electricity produced there and supplied to neighbouring states. It is likely to raise the issue again. The state will raise the issue of transfer of the 120-MW Sanan power project which should have been given to Himachal on "as is where is" basis under the Punjab State Reorganisation Act. The responsibility of implementation of the Act is on the Centre. It will also press for expeditious payment of arrears amounting to Rs 3,996 crore towards its share in the BBMB in accordance with the Supreme Court verdict. The court had directed the centre to settle matter in six months, but more than nine months have passed since then. The arrears are to be paid by Punjab and Haryana. The state will also take up the issue of construction of new rail line from Bhanupali to Leh via Bilaspur and Manali and early completion of the Nangal Talwara rail line. Chidambaram is likely to suggest ways for better information-sharing between the northern states as Jammu and Kashmir is facing a direct onslaught of terrorism that has direct fallout on adjoining Himachal and Punjab.
