    Draft Small Dock and Pier General License for Inland Structures  pdf format of Draft General License for Inland Structures

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

    M.G.L Chapter 91 S. 18C, enacted in 2011, authorized MassDEP to create a General License for non-commercial, water-dependent, small scale docks, piers and similar structures. The May 2014 revisions to the Waterways regulation created 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 General License is divided 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.
