New England Farm of Wareham has filed plans to build an automobile service station on the site of the Delta Gas & Service Center at 303 Tremont St. in South Carver. The company operates a service station on Route 28 in Wareham. Its proposal to build a station in Carver requires a site plan approval and special permit from the Planning Board. Town Planner Jack Hunter said the board will schedule a public hearing, probably for its April 16 meeting. The company is also weighing the possibility of operating a store attached to the service station on the Tremont Street property.
