The government on Thursday unveiled steps including re-introduction of a chemical marker in kerosene to reduce opportunities of the subsidized fuel being diverted for adulteration. Speaking to reporters in New Delhi, Petroleum minister Jaipal Reddy said there is a need to respond to the problem of kerosene being used for adulteration in systematic term. He said an improved chemical marker will be doped in kerosene to make its mixing with diesel near impossible. The minister said the kerosene marker system which was withdrawn in 2009 will be reintroduced in the next six months. Mr. Reddy had convened a high level meeting to take stock of the situation in the backdrop of the killing of Additional District Collector of Malegaon Yashwant Sonawane allegedly by oil mafia. Mr Reddy also suggested that the states use GPS-based vehicular tracking system like the one being used for vehicles transporting petrol and diesel to track the movement, any route deviations being taken or long stoppages. Mr Reddy said oil companies would provide technological and institutional support to the state governments for installing GPS on tank trucks transporting kerosene.The minister also said oil companies will provide online real-time information on loading of kerosene trucks, quantity and time of departure from their depots so that state authorities can check any route diversion. He urged state governments to use GSP to check pilferage, dilution and adulteration. He said government will also introduce the system of online updates. The quantity, time of departure of the truck will be uploaded online.
