WYNN RESORTS is expected to move ahead with construction of its $2.1 billion hotel-casino complex in Everett this week after Somerville decided not to seek reconsideration of an environmental  permit awarded to the project.

Denise Taylor, a spokeswoman for Somerville Mayor Joseph Curtatone, said the city does not intend to ask the state Department of Environmental Protection to reconsider its decision awarding the permit it awarded to Wynn Resorts. The decision means DEP will probably formally award the permit as early as tomorrow, allowing Wynn Resorts to begin construction of the complex.

Construction was halted in February when Curtatone appealed an earlier DEP decision granting Wynn Resorts a waterways permit for its casino complex on the Mystic River. Steve Wynn himself has dismissed the Somerville challenge as “superficial and groundless,” but the appeal nevertheless prevented the Las Vegas developer from moving forward on the project.

Taylor cautioned that Somerville’s battle against the casino may not be over. She said the city is continuing to evaluate the DEP decision and is trying to decide whether to challenge it in the courts.

Wynn Resorts officials say they will proceed with construction even if Curtatone goes to court.
