Beginning May 14, fuel outlets in eight states will be shut every Sunday following Prime Minister Modi's call to conserve oil, a fuel pump owners' body said in Chennai on Tuesday.

"We had planned to shut our outlets on Sundays a few years back. But marketing companies (OMCs) had then requested us to reconsider our decision. Now we have decided to shut the outlets on Sundays," said Suresh Kumar, an executive committee member of the consortium of Indian

He said the association's decision was made in view of the Prime Minister's call during his recent 'Mann ki baat' programme to to save the environment.

Kumar, also the vice-president of Association, said nearly 20,000 outlets in Tamil Nadu, Kerala, Karnataka, Puducherry, Andhra Pradesh, Telangana, and would be shut for 24 hours on Sundays, starting May 14.

"In Tamil Nadu, we expect a business loss of Rs 150 crore if we do not operate on a Sunday. But we have been seeing a decline in sales on Sundays by upto 40 per cent," he said.

Asked if the association's decision was supported by the OMCs, he said, "We will communicate our decision to them shortly."

Kumar said the fuel outlets which normally have about 15 staff each would have one staff member on the holidays to provide fuel if there was an emergency situation.

On the issue of hiking the margins to petroleum outlets, he said the association was discussing it and would soon make an announcement in this regard.

"That struggle is going on. We are meeting our association members shortly. We will announce our decision soon," he said.
