Chief Minister J Jayalalithaa said that there was no clarity over the continuance of Centre's subsidy scheme in this matter beyond the financial year 2014-15.
At present, levy sugar released to Tamil Nadu by Centre was 10835 MT per month which met only one third of the total requirement for distribution under PDS.
Her government was already incurring heavy expenditure towards providing subsidy for supply of sugar through the PDS, she said in a letter to Prime Minister Manmohan Singh.
The state had been informed this subsidy by Government of India will be available only for the financial years 2013-2014 and 2014-2015, adding "there is no clarity whether this arrangement will continue beyond 2014-2015."
"The sudden withdrawal of levy obligation on sugar mills will expose the supply of PDS sugar to the vagaries of the market and the resultant volatility. Further, any price fluctuation over Rs 32 per kg in the open market will have to be borne by the State, which is already saddled with a huge subsidy burden," she said.
