A new plan for cleaning up paper mill pollution streaming into Perdido Bay at the western end of the Florida Panhandle is being questioned by Alabama's attorney general.
Federal fisheries officials are also raising questions.
The 61-(m)-million-dollar project would send effluent from the International Paper Company mill to a new municipal sewage plant for treatment.
More than 37 million gallons of treated wastewater then would piped daily into a 1,500 acre wetland. The wetland would act as a natural filter as it flows toward the bay on the Florida-Alabama state line.
Alabama Attorney General Troy King expressed reservations in a letter to the Florida agency.
The Florida Department of Environmental Protection has let the mill operate although its effluent fails to meet state water quality standards while the company tries to come up with a solution.
