The Effingham Industrial Development Authority may have taken a substantial step forward in the future of its I-16 holdings. The IDA has approved submitting its 404 wetlands permit application to the U.S. Army Corps of Engineers, which the IDA needs before it can start work on the northern tract of its I-16 property. IDA members could receive a decision on their application within 90 days and also have begun the steps to purchase wetlands mitigation credits.
