Dams; prohibited vegetation, certain wetland vegetation allowed.

Exempts wetland vegetation growing on certain regulated impounding structures from the requirement that all vegetation be removed from such dams. The bill exempts vegetation associated with a wetland mitigation bank or in-lieu fee site that has regulatory approval and is the subject of a recorded, permanent instrument protecting the vegetation from removal. The bill allows the Department of Conservation and Recreation to require the dam owner to remove trees by flush cutting unless the Department determines on the basis of site-specific information that the grubbing of roots is necessary to protect the integrity of the dam.
