Residents of Massachusetts will reportedly lose $660 million annually if the delay to Wynn Resort’s casino plans for Everett continues.

State media outlets reported that the casino operator warned the state of a “dark cloud” that Somerville’s appeal of its environmental permit would bring. In a press release, Wynn Resorts said the figure includes some $242 million the casino would pay in annual taxes and fees, as well as the $170 million in payroll and the $248 million for casino operations.

In addition, “the delay will reportedly put 4,000 union construction jobs, 4,000 permanent jobs and $30 million cleanup of the former Monsanto chemical factory at risk,” Patch.com reported.

Last week, Somerville Mayor Joseph Curtatone filed an administrative appeal that questions the environmental permit that Wynn Everett received from the Department of Environmental Protection in January of this year. Curtatone believes the casino project will seriously affect “the health of city residents as an estimated 18,000 people per day are expected to drive to the casino.”
