Public Notices

  • NWO-2019-00616-DEN

    Expiration date: 3/3/2021

    SEMSWA is proposing an amendment to the original permit that includes extending the downstream limits of construction to address bank erosion that has occurred since the original plan was drafted and the permit was reviewed.

  • NWO-2020-02252-DEN

    Expiration date: 2/15/2021

    The proposed South Platte Mitigation Bank would be a private, commercial wetland mitigation bank which would allow the bank sponsor (SCP Conservation) to sell wetland and stream mitigation credits within a defined service area. Wetland credits would be created through re-establishment of historic wetlands and restoration and enhancement of existing wetlands at the project site. Stream credits would be created through the restoration and enhancement of the South Platte River. The wetland and stream mitigation credits could be used to offset compensatory mitigation requirements associated with impacts to waters of the United States authorized by Department of the Army (DA) permit requirements.
