While the district administration had directed the notified area council (NAC) to enforce the restriction on the environmentally-hazardous material, the civic body recently made a resolution to this effect to ban polythene which came into force yesterday, officials said.
Gopalpur will be taken as a pilot project in the district to ban the use of polythene bags.
"We will take similar steps in other towns and tourist places of the district depending on the the success of Gopalpur," said Ganjam district Collector, P C Chaudhary.
Higher education minister Pradeep Panigrahi, who represents Gopalpur assembly constituency in the assembly, hailed the decision of the district administration.
The civic authorities in Gopalpur used loud speakers to educate people about the decision. "Besides, we will soon distribute leaflets in the city while hotels and tea-stall owners are told not to use polythene," said KK Sahu, executive officer, Gopalpur NAC.
