State environmental officials are scheduled Thursday to hear Somerville’s appeal of a waterfront permit for a $1.7 billion casino in Everett, a challenge that has forced Wynn Resorts to delay construction.

The hearing will be held by the Department of Environmental Protection at 1 p.m. in Boston.

Somerville officials filed the appeal last month, drawing an angry response from the casino company. Wynn Resorts denounced the legal challenge as a “selfish, blatant attempt” by Somerville’s mayor, Joseph Curtatone, to politicize the casino issue for his personal benefit.

Curtatone contends the casino project is too large and would draw too much traffic to the waterfront area to qualify for the permit.


On Tuesday, Wynn Resorts announced it will halt cleanup work at the casino site because of Somerville’s appeal. The company has spent months removing arsenic, lead, and other pollutants from a portion of the 33-acre property along the Mystic River.
