From the press release:
 
Today, the Office of the Attorney General (OAG) and Maine Department of Health and Human Services (DHHS) issued guidance to businesses and other organizations which interact with the public detailing these enforcement options. The guidance clearly states that the Governors Executive Orders have the force of law and spells out face covering requirements for individuals and establishments, including which establishments must enforce wearing of face coverings, and the potential consequences for noncompliance.
 
The joint OAG-DHHS guidance explains the Executive Order on face coverings and the requirements and expectations it places on individuals and establishments. These include:
 
 

• The definition of public settings as places like stores, restaurants, and government buildings

• Clarification that all businesses may, and some businesses must enforce face covering usage, and further clarification on which businesses are legally required to do so

• Recommendations for businesses and other establishments to work with law enforcement in order to protect frontline workers who encounter individuals refusing to comply

• A reminder that individuals can be charged criminally for not wearing a face covering in a public setting after being warned by a law enforcement officer to do so
