WYNN RESORTS on Wednesday filed its latest application seeking a key state environmental permit for its proposed Everett casino, which suggests the Las Vegas company is ignoring Attorney General Maura Healey’s call on Monday for a new, independent study of transportation needs in the area.

Wynn officials said they filed the application late Wednesday; they said state officials will decide when to release it to the public. They declined further comment.

Wynn’s last application was rejected in April by Matthew Beaton, the state secretary of energy and environmental affairs, who said he wanted the casino developer to provide an annual subsidy for the Orange Line, to address the improper acquisition from the MBTA of a parcel of land next door to the casino site, and to work with Boston and state officials to develop a long-term solution to congestion in the Sullivan Square area of Charlestown.

In a recently compiled summary of transportation and mitigation efforts put together by Wynn, the company indicated it plans to offer a $380,900 annual subsidy to the MBTA for the Orange Line.

After the rejection of its last application, Wynn put the land it purchased for $6 million from the MBTA into escrow. Beaton had said the law barred the MBTA from transferring the land until after the environmental review process is completed.

On Sullivan Square, little progress has been accomplished, in part because Boston officials have refused to meet with Wynn and state transportation officials. Boston is currently suing the Massachusetts Gaming Commission, claiming Wynn obtained its license through a “corrupt process.”

Healey earlier this week sent a letter to the Department of Transportation urging the agency to require Wynn to initiate a new study of traffic demand in the area before moving ahead with the environmental permitting process. The attorney general said a study done by a Wynn consultant was not sufficient.

Healey is an outspoken opponent of casino gambling who lives in Charlestown, the Boston neighborhood that abuts the casino property.
