Forms

  • ePermits
    • The Notice of Intent (NOI) for this General Permit is submitted electronically through the ePermits website, as are Notices of Termination, Transfers, and the Declaration of Intent (DOI).
    • The NOI and DOI must be electronically signed by the person in authority from the developer or builder; however, the system will allow agents and consultants to prepare any part of the NOI necessary, then send it to the person who will submit it as the responsible party.
    • Federal regulations require that applicants must submit certain information to MDE to validate their authorization to submit an NOI on behalf of a responsible party.  To meet this requirement, MDE developed a Subscriber Agreement Template Form (.docpdf).
    • Technical issues with the system should be submitted to the technical support team via the 24/7 Support link at the top of the system screen.
    • Public Notification Period - When NOIs with a signed Declaration of Intent (DOI) are submitted to MDE, a 14 day Public Notification Period​ is initiated and information is published on MDE's website.  Interested parties may review NOIs during the public notification period.  Please contact the appropriate Erosion and Sediment Control (E&SC) authority to review plans.  Interested parties may submit concerns about the E&SC to the approval authority and to MDE.  Concerns should be supported by a detailed, written explanation as to why the E&SC Plan fails to meet State standards.
