  • Draft Small Dock and Pier General License

    Response to Comments - General License pdf format of Response to Comments - General License

    Notice of Appeal Rights - Small Dock and Pier General License pdf format of Notice of Appeal Rights - General License

    The Legislature amended M.G.L Chapter 91 in 2011 with the new Section 18C allowing MassDEP to create the General License for non-commercial, water-dependent, small scale docks, piers and similar structures. MassDEP amended waterways regulations in spring 2014, creating eligibility criteria, general performance standards, and procedures for certification and renewal. The new certification process streamlines state review and eliminates Governor signature of individual licenses. The review process and public comment period allowed for the division of the General License into two separate licenses for Coastal and Inland Structures. These two licenses will be issued once the twenty-one (21) day appeal period ends and upon signature of the Governor. The licenses will then be recorded at all of the Registries in the Commonwealth, and the Department's Certification of an applicant's eligibility shall also be recorded against the title of the property on which the authorized structure is located.
