02/18/2015: Due to the reinstatement of five (5) Nationwide Permits by the Army Corps of Engineers, IDEM has modified the Section 401 Water Quality Certification which authorizes the use of the Nationwide Permits [PDF] in the state of Indiana. These five (5) Nationwide Permits have been approved and conditions have been placed on the activities to ensure compliance with Indiana’s water quality standards.
