In 2017, the Senate voted to impose an amendment which makes 50 milliliter and smaller liquor bottles "subject to a refund value of not more than 5¢." All wine/liquor containers larger than 50 milliliters remain at deposit values of no less than 15¢.
Distributors who initiate deposits have the obligation to pick up containers from the dealers they deliver to or from the licensed redemption center that serves those dealers. There is a per container fine of $100 for accepting containers purchased out of state for redemption.
To prevent out-of-state redemption fraud, rules were added in 2009, requiring people wishing to redeem more than 2,500 beverage containers at a time to provide their name, license plate number, and address each time they return containers in bulk. Exceptions are made for nonprofit organizations. Other changes made at this time include a limit on the number of redemption centers in a municipality, based on population, and a requirement for dealers or redemption centers to accept plastic wrap used for beverage containers.
In 2019, the law was revised to prohibit the Department of Environmental Protection (DEP) from issuing new redemption center licenses from May 2, 2019 to January 15, 2020.
Provisions for "commingling agreements" exist in the Maine legislation to increase the efficiency of the redemption process. The following information from a study by the Maine Department of Agriculture. 
"Commingling groups” which represent approximately 2/3 of the beverage industry are 2 or more initiators of deposit (distributors) of beverage containers for which they have initiated deposits to be commingled by dealers and redemption centers. The advantages of comingling agreements allow for the commingling of beverage containers by like product group (beer, wine, spirits and soft drinks etc.) material and size.
Distributors who are members of a commingling agreement pick up all other beverage containers subject to the agreement in assigned geographical locations. The end result is less sorting for redemption centers and less handling and transportation costs for distributors.
By default all unclaimed deposits must be transferred monthly to the state of Maine, but this does not apply to containers that are subject to a commingling agreement. 
Redemption information in Maine has been historically difficult to track down. A 2007 survey by the Maine Department of Agriculture contains some redemption and sales information, but was unable to find any "reliable conclusions" due to lack of participation. In 2017, beverage industry sources reported a redemption rate of 84% . In 2019, the law was revised to require deposit initiators to report the number of beverage containers picked up in 2018.
