Indoor mask mandates for two Maine cities take effect on Monday.South Portland's mandate was adopted after the City Council last week directed the city manager to issue the emergency mask mandate for everyone older than 2.Businesses will be required to post signs by Wednesday that masks are required.The city said it will work on providing masks to businesses so they can offer them to customers who might not have one.Officials said that while businesses are the first line of defense in enforcing the mandate, people can report violations through the city’s reporting website or by calling the city manager’s office at 207-767-7606.The city said the mask mandate will remain in effect until it is either rescinded by the city manager or the emergency proclamation is terminated by the mayor.Bath is also implementing a mask mandate for indoor public spaces effective Monday. The Bath City Council unanimously approved the mandate last week and it lasts for 60 days.South Portland and Bath join Portland and Brunswick in adopting mask mandates amid the surge of the omicron variant in the state.
