The St. Pauls Board of Commissioners voted Thursday to apply for a grant to study the feasibility of Lumberton treating the town's sewage, although some commissioners have reservations about giving up control of the sewer system. St. Pauls Administrator J.R. Steigerwald said Lumberton requested that the town sign-on to the effort to secure a state Department of Environmental Quality grant to study the feasibility of a regional sewer treatment.
