SPRINGFIELD, Mass. (AP) — Springfield Mayor Domenic Sarno is set to announce the city’s deal or deals for a casino community host agreement.

The announcement set for Tuesday morning is the first step toward a local referendum on which casino application to support.

Springfield has been in talks with MGM Resorts International and Penn National Gaming, each of which has proposed $800 million projects. MGM has a plan to build in the South End, and Penn National in the North End.

The state’s casino law allows the state gambling commission to award one license for western Massachusetts. Besides Springfield, casinos have been proposed in Palmer by Mohegan Sun, and in West Springfield by Hard Rock International.
