Boston - MGM Resorts International is nearing a final ruling on its bid to become Massachusetts' first licensed casino operator, with a proposed $800 million project in Springfield.

Starting Tuesday, the Massachusetts Gaming Commission will hold a series of meetings in Springfield and Boston leading up to a Friday vote in Springfield on who receives the western region casino license.

MGM, which owns the Mirage, Bellagio, MGM Grand and other casinos, is the lone operator standing in a once-crowded field.

Plans by Penn National Gaming and Ameristar Casinos never went before Springfield voters, while proposals by Mohegan Sun in Palmer and Hard Rock International in West Springfield were defeated in local referendums.

MGM's plan for a casino, hotel, shopping and entertainment complex on 14½ acres straddling the city's downtown and South End neighborhood was approved by Springfield voters last July.

Still, commission members have been reluctant to describe MGM as a shoe-in, noting the panel has reserved the right to not issue a license now or to impose stipulations or conditions on issuing the license.

Stephen Crosby, chairman of the Massachusetts Gaming Commission, said recently he doesn't expect the five-member commission will need all four days to make its decision. Each commission member is expected to present findings on one of five areas of MGM's 236-page application that they have been tasked to review.

Crosby, for example, will give an overview of the proposal, including how it "manifests an appreciation" for the Massachusetts "brand," "leverages Massachusetts' existing assets" and enhances the state's existing tourism and leisure venues, according to the commission's evaluation guidelines.

Other commissioners will look at the project's finances, economic impacts, building and site design and impacts on local traffic patterns, gambling addiction and the state lottery.
