Haryana Chief Secretary Dharam Vir said on Wednesday that there was no ban on purchase of wheat by private traders or big companies in the State. However, the companies purchasing wheat above 10,000 tonnes would have to file returns to the State Government. Addressing media persons, he disclosed that earlier the limit for filing the returns to the Central Government on purchase of wheat was 50,000 tonnes which had now been reduced to 25,000 tonnes. The farmers were free to sell their products to private parties in case they got better prices, he added. Replying to a question on the State Government's "hesitation' in paying its share for the international airport at Chandigarh, he clarified that the question of backing out did not arise and the payment would be made by the Haryana Urban Development Authority. On the proposal that metro railway be introduced in the three satellite cities of Panchkula, Chandigarh and Mohali, he said a meeting was held recently and it was decided to first prepare a Comprehensive Mobility Plan which would identify the different routes and quantify the quantum of traffic on these routes. Based on this plan, the consultants would advise which technology would be best suited for this area. The consultants would also chalk out the cost effectiveness, durability and sustainability of the metro system. He said two upcoming projects, the Delhi-Mumbai Industrial Corridor and the Delhi-Ambala-Amritsar fast rail track, would be very beneficial for increasing both rail and road connectivity in Haryana.
