To all interested parties: This letter shall serve as a formal notice of the receipt of an application for Section 401 Water Quality Certification by the Indiana Department of Environmental Management (IDEM). The purpose of the notice is to inform the public of active applications submitted for water quality certification under Section 401 of the Clean Water Act (33 U.S.C. § 1341) and to solicit comments and information on any impacts to water quality related to the proposed project. IDEM will evaluate whether the project complies with Indiana’s water quality standards as set forth at 327 IAC 2.

3. Project location: 1097 North 950 West Owensville, Gibson County
4. Affected waterbody: Emergent Wetland
5. Project Description: The applicant proposes to permanently impact 0.39 acre of emergent wetland with the placement of fill materialassociated with modifications to the east and south slopes of the final cover for the RWS II Landfill at the Duke Energy Gibson East Generating Station. To compensate for the permanent wetland impacts, the applicant proposes to purchase 0.78 acre of emergent wetland mitigation credit from the Indiana Stream and Wetland Mitigation Program within the Lower Wabash Service Area. In addition, the applicant proposes to temporarily impact 0.67 acre of emergent wetland for placement of a temporary work pad during construction activities. Upon completion of the project, the work pad will be removed, and the wetland areas will be returned to original grade and seeded with a native emergent wetland seed mix.

Public Hearing: Any person may submit a written request that a public hearing be held to consider issues related to water quality in connection with the project detailed in this notice. The request for a hearing should be submitted within the comment period to be considered timely. The request should also state the reason for the public hearing as specifically as possible to assist IDEM in determining whether a public hearing is warranted.
